Definitions

  • the present invention relates to the field of flexible tubes comprising a cap sealing the neck prior to the first use of the tube, and a perforating plug adapted to perform the piercing of the cap.
  • Tubes provided with a cap associated with a perforating plug comprising a punch adapted to perforate said cap.
  • the seal makes it possible to keep the product contained in the tube hermetically during storage before its first use, which represents a very important part of the overall service life of the tube.
  • plugs in which the punch is disposed in the plug and protrudes from it so as to perforate the cap when the cap is screwed on the tube head.
  • a ring is disposed between the cap and the shoulder of the tube head, so as to keep the punch away from the cap when the cap is screwed on the neck.
  • the user To pierce and / or cut the lid, the user must first unscrew the cap, then remove the ring and finally screw the cap until the lid is pierced and / or cut.
  • the number of steps is binding for the user who often does not understand what the ring is for and does not necessarily understand that a cap must be pierced before a first use of the tube.
  • Such an assembly allows the cap to be held in the waiting position without having to use an additional piece other than the neck and the stopper.
  • the free end of the punch protruding from the plug is kept away from the seal closing the neck and the seal is thus preserved from any perforation or cutting prior to the first use of the tube by a user simply and reliably without complicating the closure assembly.
  • such an assembly makes it possible to refrain from using the spacer ring generally used in such a system to keep the punch away from the lid.
  • Plug means an object for sealing a receptacle, in particular an outlet opening of a product, in a reversible manner.
  • a plug according to the invention can thus move from an open position to a closed position and vice versa, mainly by a screwing movement or the like.
  • the present invention does not include closure assemblies, such as a hinged service capsule, permanently fixed on opening and comprising a passage opening for the outlet of the product and a folding cap for closing said orifice.
  • the invention also relates to a tube comprising an assembly as described above.
  • the tube head 5 a variant of which is presented on the figures 1 and 3 to 8 , comprises the neck 7 defining a longitudinal axis ZZ, a shoulder 11 and a solid insert 13 forming a cap 15 closing said neck 7, at the bottom of the latter.
  • said neck 7 and said shoulder 11 are designed in one piece and are continuously continuous.
  • the insert 13 is located against a lower face of the shoulder 11, intended to be oriented towards the inside of the tube.
  • Said neck 7 is here in the form of a cylinder extending from an upper end located towards the outside of said tube 3 towards a lower end opposite to the upper end and directed towards the inside of said tube 3.
  • Said upper end has an outlet port 7a for the output of said product contained in the tube.
  • the lower end is adjacent to said shoulder 11.
  • Said shoulder 11 extends from the lower end of said neck to an outer periphery, here cylindrical, in a direction substantially perpendicular to the axis ZZ, that is to say the portion of the tube head going to flaring from said neck 7.
  • Said shoulder 11 is configured so that a tube skirt can be fixed, particularly at its periphery, to form said tube 3.
  • the insert 13 comprises a peripheral section, typically of frustoconical or disc shape, and a central section forming said cap 15, whose diameter typically corresponds to the internal diameter of the neck 7.
  • the plug 9, an example of which is illustrated in FIG. figure 2 comprises a punch 17 projecting from said plug 9.
  • Said punch 17 is notably derived from the material of said plug 9.
  • Said punch 17 is configured to be inserted inside the neck 7 of the tube head 5 when the plug 9 is fixed on said neck 7. It defines a longitudinal direction of the cap 9, corresponding to the longitudinal axis ZZ of the neck 7 when the cap 9 is fixed on the neck 7.
  • Said punch 17 allows cutting and / or perforation of the lid 15.
  • the cutting is advantageously partial, so that the portion or portions of the lid 15 having been cut remain connected to the rest of the insert, warning and any mixture of the material forming the insert with a product contained in the associated tube 3, and a possible distribution of this material to the user.
  • said punch 17 has a cylindrical section of revolution, a free end of which is advantageously provided with cutting means so that when the cap 9 is fixed, for example screwed, on the neck 7 of the tube head 5, the free end of the punch 17 is inserted into the neck 7.
  • Said cutting means may be a beveled shape of the free end, teeth and / or cutting notches, for example, evenly distributed around the periphery of the free end of the punch 17.
  • the example of punch 17 shown in FIGS. figures 2 and 4 to 8 is a punch 17 of cylindrical section of revolution, whose free end is provided with three teeth 19 of low height and evenly distributed around the periphery of its free end.
  • said neck 7 and said cap 9 are configured to allow said cap 9 to be fixed fixed on said neck 7 in a first position, called the waiting position ( Figures 3 to 5 and 14a, 14b ), in which the punch 17 is kept at a distance from the cover 15 and in a second position, called the position of use ( figures 8 and 15a, 15b ), wherein said punch 17 pierces said lid 15.
  • Said neck 7 and said cap 9 can also be configured to allow said stopper 9 to be held in a third position, called the closed position ( figures 7 and 16a, 16b ), wherein said neck 7 and said cap 9 seal said tube 3.
  • said plug 9 is configured to move from the waiting position to the position of use and / or from the position of use to the closed position by at least one rotational movement.
  • said rotational movement can also be simultaneously accompanied by an axial movement along the Z-Z axis. It is then a helical movement.
  • the axial movement is effected after the rotational movement.
  • said plug 9 is configured to move from the waiting position to the use position and / or the use position to the closed position essentially by a movement always going in the same direction, that is to say the direction of rotation is always the same.
  • the passage of said cap 9 from the waiting position to the position of use and / or the position of use to the closed position is reversible. It is thus possible to open said tube and then close it after use, and vice versa.
  • said neck 7 comprises at least a first blocking means configured to cooperate with said plug 9 to maintain said plug 9 in the waiting position.
  • said neck 7 and said cap 9 each comprise at least one blocking means cooperating together to hold said cap 9 in the waiting position.
  • said first locking means are a ring 25 located on an external surface of said neck 7 and said second locking means are protuberances 27a, 27b located on an inner surface of said plug 9.
  • said cap 9 is thus held in the waiting position by snapping said cap 9 on said neck 7, in particular by snapping the ring 25 with said protuberances 27a, 27b.
  • said protuberances 27a, 27b are regularly distributed around the periphery of said plug 9, in particular on the lower part of said plug 9.
  • the protuberances 27a, 27b are distributed in two rows, separated axially, and are angularly offset between the two rows so that the ring 25 is located between said protuberances 27a, 27b, in the waiting position of the cap 9.
  • each row comprises at least two protuberances 27a, 27b, or at least less three or at least four.
  • each of the rows comprises four protuberances 27a, 27b.
  • the lower row of protuberances 27a makes it possible to hold said cap 9 fixed on said neck 7 and to avoid an unwanted withdrawal of said plug 9.
  • the upper row of excrescences 27b makes it possible to limit the movement of said cap 9 downwards when the one it is fixed on the neck 7 and thus keep the punch 17 away from the lid 15 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.
  • the ring 25 is made from the material of said neck 7 and is all around said neck 7.
  • Said ring 25 comprises a lower surface 25a directed towards the shoulder 11 of the tube head 5 and a top surface 25b directed to the outlet orifice 7a of said neck 7.
  • Said lower 25a and upper 25b surfaces are substantially flat and their radial extension allows the snap ring 25 between said protuberances 27a, 27b.
  • the ring 25 comprises in particular a thinned end to facilitate its snapping between the protuberances 27a, 27b and its disengagement thereof for the user to easily move from the waiting position to the position of use and then the position of Use in removing the plug 9.
  • the protuberances 27a, 27b may also have a thinned end, as is visible here. More specifically, here said ring 25 has a cross section of trapezoidal or triangular shape of rounded apex and / or said protuberances 27a, 27b have a rounded cross section.
  • said neck 7 and said plug 9 each comprise a thread, said first thread 29 and second thread 31 cooperating together to allow the passage of said plug 9 from the waiting position to the position of use by screwing by the user of said cap 9 on the neck 7.
  • said rotation movement and said axial movement described above are simultaneous and causes said screwing, in a helical movement.
  • Said cap 9 is then fixed by screwing to said neck 7, while in the waiting position, preferably, said threads 29 and 31 are not engaged.

Description

La présente invention concerne le domaine des tubes souples comprenant un opercule obturant le goulot préalablement à la première utilisation du tube, et un bouchon perforateur adapté pour réaliser le perçage de l'opercule.The present invention relates to the field of flexible tubes comprising a cap sealing the neck prior to the first use of the tube, and a perforating plug adapted to perform the piercing of the cap.

On connait les tubes munis d'un opercule associés à un bouchon perforateur comprenant un poinçon adapté pour perforer ledit opercule.Tubes provided with a cap associated with a perforating plug are known comprising a punch adapted to perforate said cap.

L'opercule permet en effet de conserver le produit contenu dans le tube de manière hermétique pendant son stockage préalablement à sa première utilisation, ce qui représente une part très importante de la durée de vie globale du tube.The seal makes it possible to keep the product contained in the tube hermetically during storage before its first use, which represents a very important part of the overall service life of the tube.

Il existe des bouchons dans lesquels le poinçon est disposé dans le bouchon et fait saillie de celui-ci de manière à pouvoir perforer l'opercule lorsque le bouchon est vissé sur la tête de tube. Afin d'assurer la préservation de l'opercule préalablement à la première utilisation, une bague est disposée entre le bouchon et l'épaule de la tête de tube, de manière à maintenir le poinçon à distance de l'opercule lorsque le bouchon est vissé sur le goulot.There are plugs in which the punch is disposed in the plug and protrudes from it so as to perforate the cap when the cap is screwed on the tube head. To ensure the preservation of the cap prior to the first use, a ring is disposed between the cap and the shoulder of the tube head, so as to keep the punch away from the cap when the cap is screwed on the neck.

Pour percer et/ou découper l'opercule, l'utilisateur doit d'abord dévisser le bouchon, puis enlever la bague et enfin revisser le bouchon jusqu'à ce que l'opercule soit percé et/ou découpé. Le nombre d'étapes est contraignant pour l'utilisateur qui souvent ne comprend pas à quoi sert la bague et ne comprend pas forcément non plus qu'un opercule doit être percé avant une première utilisation du tube.To pierce and / or cut the lid, the user must first unscrew the cap, then remove the ring and finally screw the cap until the lid is pierced and / or cut. The number of steps is binding for the user who often does not understand what the ring is for and does not necessarily understand that a cap must be pierced before a first use of the tube.

Il existe donc un besoin d'un ensemble pour la fermeture d'un tube qui pallie au moins en partie les inconvénients précités.There is therefore a need for an assembly for closing a tube which at least partially overcomes the aforementioned drawbacks.

A cet effet, la présente invention propose un ensemble pour la fermeture d'un tube, ledit ensemble comprenant :

  • une tête de tube comprenant un goulot et un opercule obturant ledit goulot,
  • un bouchon comprenant un poinçon adapté pour découper ledit opercule, ledit goulot et ledit bouchon étant configurés pour permettre de maintenir ledit bouchon fixé sur ledit goulot dans une première position, dite position d'attente dans laquelle le poinçon est maintenu à distance de l'opercule et dans une seconde position, dite position d'utilisation, dans laquelle ledit poinçon perce ledit opercule.
For this purpose, the present invention provides an assembly for closing a tube, said assembly comprising:
  • a tube head comprising a neck and a cap closing said neck,
  • a stopper comprising a punch adapted to cut said lid, said neck and said cap being configured to allow said plug to be fixed on said neck in a first position, said waiting position in which the punch is kept at a distance from the cap and in a second position, said position of use wherein said punch pierces said seal.

Un tel ensemble permet au bouchon d'être maintenu en position d'attente sans devoir utiliser une pièce supplémentaire autre que le goulot et le bouchon. Autrement dit, l'extrémité libre du poinçon faisant saillie du bouchon est maintenue éloignée de l'opercule obturant le goulot et l'opercule est ainsi préservé de toute perforation ou découpe préalablement à la première utilisation du tube par un utilisateur de manière simple et fiable sans compliquer l'ensemble de fermeture. Notamment un tel ensemble permet de s'abstenir d'utiliser la bague d'espacement généralement utilisée dans de tel système pour maintenir le poinçon éloigné de l'opercule.Such an assembly allows the cap to be held in the waiting position without having to use an additional piece other than the neck and the stopper. In other words, the free end of the punch protruding from the plug is kept away from the seal closing the neck and the seal is thus preserved from any perforation or cutting prior to the first use of the tube by a user simply and reliably without complicating the closure assembly. In particular, such an assembly makes it possible to refrain from using the spacer ring generally used in such a system to keep the punch away from the lid.

On entend par bouchon un objet permettant l'obturation étanche d'un réceptacle, notamment d'une ouverture de sortie d'un produit, de manière réversible. Un bouchon selon l'invention peut ainsi passer d'une position d'ouverture à une position de fermeture et inversement, principalement par un mouvement de vissage ou équivalent. La présente invention n'inclut pas les ensembles de fermeture, telle qu'une capsule service à charnière, fixés sur ouverture de manière définitive et comprenant un orifice de passage pour la sortie du produit et une coiffe rabattable permettant d'obturer ledit orifice.Plug means an object for sealing a receptacle, in particular an outlet opening of a product, in a reversible manner. A plug according to the invention can thus move from an open position to a closed position and vice versa, mainly by a screwing movement or the like. The present invention does not include closure assemblies, such as a hinged service capsule, permanently fixed on opening and comprising a passage opening for the outlet of the product and a folding cap for closing said orifice.

As illustrated in the various figures, the invention relates to an assembly 1 for closing a tube 3. Said assembly 1 comprises:
  • a tube head 5 comprising a neck 7, and
  • a plug 9 configured to be fixed on said neck 7, in particular by screwing.

La tête de tube 5, dont une variante est présentée sur les figures 1 et 3 à 8, comprend le goulot 7 définissant un axe longitudinal Z-Z, une épaule 11 et un insert 13 plein formant un opercule 15 obturant ledit goulot 7, en partie basse de ce dernier. Comme représenté ici, ledit goulot 7 et ladite épaule 11 sont conçus en une seule pièce et sont en continuité de manière. L'insert 13 est situé contre une face inférieure de l'épaule 11, destinée à être orientée vers l'intérieur du tube.The tube head 5, a variant of which is presented on the figures 1 and 3 to 8 , comprises the neck 7 defining a longitudinal axis ZZ, a shoulder 11 and a solid insert 13 forming a cap 15 closing said neck 7, at the bottom of the latter. As shown here, said neck 7 and said shoulder 11 are designed in one piece and are continuously continuous. The insert 13 is located against a lower face of the shoulder 11, intended to be oriented towards the inside of the tube.

Ledit goulot 7 est, ici, en forme de cylindre s'étendant d'une extrémité supérieure située vers l'extérieur dudit tube 3 vers une extrémité inférieure opposée à l'extrémité supérieure et dirigée vers l'intérieur dudit tube 3. Ladite extrémité supérieure présente un orifice de sortie 7a permettant la sortie dudit produit contenu dans le tube. L'extrémité inférieure est adjacente à ladite épaule 11.Said neck 7 is here in the form of a cylinder extending from an upper end located towards the outside of said tube 3 towards a lower end opposite to the upper end and directed towards the inside of said tube 3. Said upper end has an outlet port 7a for the output of said product contained in the tube. The lower end is adjacent to said shoulder 11.

Ladite épaule 11 s'étend de l'extrémité inférieure dudit goulot vers une périphérie externe, ici cylindrique, selon une direction essentiellement perpendiculaire à l'axe Z-Z, c'est-à-dire la partie de la tête de tube allant en s'évasant à partir dudit goulot 7. Ladite épaule 11 est configurée de manière à ce qu'une jupe de tube puisse être fixée, notamment au niveau de sa périphérie, pour former ledit tube 3.Said shoulder 11 extends from the lower end of said neck to an outer periphery, here cylindrical, in a direction substantially perpendicular to the axis ZZ, that is to say the portion of the tube head going to flaring from said neck 7. Said shoulder 11 is configured so that a tube skirt can be fixed, particularly at its periphery, to form said tube 3.

Plus précisément, l'insert 13 comprend une section périphérique, typiquement de forme tronconique ou de disque, et une section centrale formant ledit opercule 15, dont le diamètre correspond typiquement au diamètre interne du goulot 7.More specifically, the insert 13 comprises a peripheral section, typically of frustoconical or disc shape, and a central section forming said cap 15, whose diameter typically corresponds to the internal diameter of the neck 7.

De manière générale, le bouchon 9, dont un exemple est illustré à la figure 2, comprend un poinçon 17 faisant saillie dudit bouchon 9. Ledit poinçon 17 est notamment issu de matière dudit bouchon 9. Ledit poinçon 17 est configuré de manière à être inséré à l'intérieur du goulot 7 de la tête de tube 5 lorsque le bouchon 9 est fixé sur ledit goulot 7. On définit une direction longitudinale du bouchon 9, correspondant à l'axe longitudinal Z-Z du goulot 7 lorsque le bouchon 9 est fixé sur le goulot 7.In general, the plug 9, an example of which is illustrated in FIG. figure 2 , comprises a punch 17 projecting from said plug 9. Said punch 17 is notably derived from the material of said plug 9. Said punch 17 is configured to be inserted inside the neck 7 of the tube head 5 when the plug 9 is fixed on said neck 7. It defines a longitudinal direction of the cap 9, corresponding to the longitudinal axis ZZ of the neck 7 when the cap 9 is fixed on the neck 7.

Ledit poinçon 17 permet la découpe et/ou la perforation de l'opercule 15. La découpe est avantageusement partielle, de manière à ce que la ou les portions de l'opercule 15 ayant été découpées demeurent liées au reste de l'insert, prévenant ainsi tout mélange du matériau formant l'insert avec un produit contenu dans le tube 3 associé, et une éventuelle distribution de ce matériau à l'utilisateur.Said punch 17 allows cutting and / or perforation of the lid 15. The cutting is advantageously partial, so that the portion or portions of the lid 15 having been cut remain connected to the rest of the insert, warning and any mixture of the material forming the insert with a product contained in the associated tube 3, and a possible distribution of this material to the user.

De manière générale, ledit poinçon 17 présente une section cylindrique de révolution, dont une extrémité libre est avantageusement munie de moyens de découpe de manière à ce que lorsque le bouchon 9 est fixé, par exemple vissé, sur le goulot 7 de la tête de tube 5, l'extrémité libre du poinçon 17 soit insérée dans le goulot 7. Lesdits moyens de découpe peuvent être une forme en biseau de l'extrémité libre, des dents et/ou des encoches de découpe, par exemple, régulièrement réparties sur le pourtour de l'extrémité libre du poinçon 17. L'exemple de poinçon 17 représenté aux figures 2 et 4 à 8 est un poinçon 17 de section cylindrique de révolution, dont l'extrémité libre est munie de trois dents 19 de faible hauteur et régulièrement réparties sur le pourtour de son extrémité libre.In general, said punch 17 has a cylindrical section of revolution, a free end of which is advantageously provided with cutting means so that when the cap 9 is fixed, for example screwed, on the neck 7 of the tube head 5, the free end of the punch 17 is inserted into the neck 7. Said cutting means may be a beveled shape of the free end, teeth and / or cutting notches, for example, evenly distributed around the periphery of the free end of the punch 17. The example of punch 17 shown in FIGS. figures 2 and 4 to 8 is a punch 17 of cylindrical section of revolution, whose free end is provided with three teeth 19 of low height and evenly distributed around the periphery of its free end.

Selon la présente invention, ledit goulot 7 et ledit bouchon 9 sont configurés pour permettre de maintenir ledit bouchon 9 fixé sur ledit goulot 7 dans une première position, dite position d'attente (figures 3 à 5 et 14a, 14b), dans laquelle le poinçon 17 est maintenu à distance de l'opercule 15 et dans une seconde position, dite position d'utilisation (figures 8 et 15a, 15b), dans laquelle ledit poinçon 17 perce ledit opercule 15.According to the present invention, said neck 7 and said cap 9 are configured to allow said cap 9 to be fixed fixed on said neck 7 in a first position, called the waiting position ( Figures 3 to 5 and 14a, 14b ), in which the punch 17 is kept at a distance from the cover 15 and in a second position, called the position of use ( figures 8 and 15a, 15b ), wherein said punch 17 pierces said lid 15.

Ledit goulot 7 et ledit bouchon 9 peuvent également être configurés pour permettre de maintenir ledit bouchon 9 dans une troisième position, dite position de fermeture (figures 7 et 16a, 16b), dans laquelle ledit goulot 7 et ledit bouchon 9 assurent une étanchéité dudit tube 3.Said neck 7 and said cap 9 can also be configured to allow said stopper 9 to be held in a third position, called the closed position ( figures 7 and 16a, 16b ), wherein said neck 7 and said cap 9 seal said tube 3.

De façon avantageuse ledit bouchon 9 est configuré pour passer de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture par au moins un mouvement de rotation.Advantageously, said plug 9 is configured to move from the waiting position to the position of use and / or from the position of use to the closed position by at least one rotational movement.

Dans certains modes de réalisation, ledit mouvement de rotation peut également être accompagné simultanément d'un mouvement axial selon l'axe Z-Z. Il s'agit alors d'un mouvement hélicoïdale.In some embodiments, said rotational movement can also be simultaneously accompanied by an axial movement along the Z-Z axis. It is then a helical movement.

Dans d'autres modes de réalisation, le mouvement axial est effectué après le mouvement de rotation.In other embodiments, the axial movement is effected after the rotational movement.

De façon avantageuse, ledit bouchon 9 est configuré pour passer de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture essentiellement par un mouvement allant toujours dans le même sens, autrement dit le sens de rotation est toujours le même.Advantageously, said plug 9 is configured to move from the waiting position to the use position and / or the use position to the closed position essentially by a movement always going in the same direction, that is to say the direction of rotation is always the same.

De façon avantageuse, le passage dudit bouchon 9 de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture est réversible. Il est ainsi possible d'ouvrir ledit tube puis de le fermer après utilisation, et inversement.Advantageously, the passage of said cap 9 from the waiting position to the position of use and / or the position of use to the closed position is reversible. It is thus possible to open said tube and then close it after use, and vice versa.

De façon avantageuse, ledit goulot 7 comprend au moins un premier moyen de blocage configuré pour coopérer avec ledit bouchon 9 pour maintenir ledit bouchon 9 en position d'attente.Advantageously, said neck 7 comprises at least a first blocking means configured to cooperate with said plug 9 to maintain said plug 9 in the waiting position.

Dans un premier mode de réalisation, ledit goulot 7 et ledit bouchon 9 comprennent chacun au moins un moyen de blocage coopérant ensemble pour maintenir ledit bouchon 9 en position d'attente.In a first embodiment, said neck 7 and said cap 9 each comprise at least one blocking means cooperating together to hold said cap 9 in the waiting position.

Dans l'exemple de ce premier mode de réalisation illustré ici aux figures 1 à 7, le ou lesdits premiers moyens de blocage sont un anneau 25 situé sur une surface externe dudit goulot 7 et le ou lesdits seconds moyens de blocage sont des excroissances 27a, 27b situées sur une surface interne dudit bouchon 9.In the example of this first embodiment illustrated here at Figures 1 to 7 said first locking means are a ring 25 located on an external surface of said neck 7 and said second locking means are protuberances 27a, 27b located on an inner surface of said plug 9.

Dans cet exemple, ledit bouchon 9 est ainsi maintenu en position d'attente par encliquetage dudit bouchon 9 sur ledit goulot 7, notamment par encliquetage de l'anneau 25 avec lesdits excroissances 27a, 27b.In this example, said cap 9 is thus held in the waiting position by snapping said cap 9 on said neck 7, in particular by snapping the ring 25 with said protuberances 27a, 27b.

De façon avantageuse, lesdites excroissances 27a, 27b sont régulièrement réparties sur le pourtour dudit bouchon 9, notamment sur la partie inférieure dudit bouchon 9. Dans l'exemple illustré ici, les excroissances 27a, 27b sont réparties sur deux rangées, séparées axialement, et sont décalées angulairement entre les deux rangées de manière à ce que l'anneau 25 soit localisé entre lesdites excroissances 27a, 27b, en position d'attente du bouchon 9. De préférence, chaque rangée comprend au moins deux excroissances 27a, 27b, voire au moins trois, voire au moins quatre. Ici, chacune des rangées comprend quatre excroissances 27a, 27b.Advantageously, said protuberances 27a, 27b are regularly distributed around the periphery of said plug 9, in particular on the lower part of said plug 9. In the example illustrated here, the protuberances 27a, 27b are distributed in two rows, separated axially, and are angularly offset between the two rows so that the ring 25 is located between said protuberances 27a, 27b, in the waiting position of the cap 9. Preferably, each row comprises at least two protuberances 27a, 27b, or at least less three or at least four. Here, each of the rows comprises four protuberances 27a, 27b.

La rangée inférieure d'excroissances 27a permet de maintenir ledit bouchon 9 fixé sur ledit goulot 7 et d'éviter un retrait non désiré dudit bouchon 9. La rangée supérieure d'excroissances 27b permet de limiter le mouvement dudit bouchon 9 vers le bas lorsque celui-ci est fixé sur le goulot 7 et de maintenir ainsi le poinçon 17 éloigné de l'opercule 15 et d'éviter la perforation et/ou la découpe de celle-ci sans l'intervention de l'utilisateur avant la première utilisation.The lower row of protuberances 27a makes it possible to hold said cap 9 fixed on said neck 7 and to avoid an unwanted withdrawal of said plug 9. The upper row of excrescences 27b makes it possible to limit the movement of said cap 9 downwards when the one it is fixed on the neck 7 and thus keep the punch 17 away from the lid 15 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.

De façon avantageuse, l'anneau 25 est issu de matière dudit goulot 7 et fait tout le tour dudit goulot 7. Ledit anneau 25 comprend une surface inférieure 25a dirigée vers l'épaule 11 de la tête de tube 5 et une surface supérieure 25b dirigée vers l'orifice de sortie 7a dudit goulot 7. Lesdites surfaces inférieure 25a et supérieure 25b sont sensiblement planes et leur extension radiale permet l'encliquetage de l'anneau 25 entre lesdites excroissances 27a, 27b. L'anneau 25 comprend notamment une extrémité amincie pour faciliter son encliquetage entre les excroissances 27a, 27b et son désengagement de ceux-ci pour que l'utilisateur passe aisément de la position d'attente à la position d'utilisation puis de la position d'utilisation au retrait du bouchon 9. De façon similaire, les excroissances 27a, 27b peuvent également présenter une extrémité amincie, comme c'est visible ici. Plus précisément, ici ledit anneau 25 présente une section droite de forme trapézoïdale ou triangulaire de sommet arrondi et/ou lesdites excroissances 27a, 27b présentent une section droite arrondie.Advantageously, the ring 25 is made from the material of said neck 7 and is all around said neck 7. Said ring 25 comprises a lower surface 25a directed towards the shoulder 11 of the tube head 5 and a top surface 25b directed to the outlet orifice 7a of said neck 7. Said lower 25a and upper 25b surfaces are substantially flat and their radial extension allows the snap ring 25 between said protuberances 27a, 27b. The ring 25 comprises in particular a thinned end to facilitate its snapping between the protuberances 27a, 27b and its disengagement thereof for the user to easily move from the waiting position to the position of use and then the position of Use in removing the plug 9. Similarly, the protuberances 27a, 27b may also have a thinned end, as is visible here. More specifically, here said ring 25 has a cross section of trapezoidal or triangular shape of rounded apex and / or said protuberances 27a, 27b have a rounded cross section.

De façon avantageuse, ledit goulot 7 et ledit bouchon 9 comprennent chacun un filetage, dit premier filetage 29 et second filetage 31 coopérant ensemble pour permettre le passage dudit bouchon 9 de la position d'attente à la position d'utilisation par vissage par l'utilisateur dudit bouchon 9 sur le goulot 7. Dans ce mode de réalisation ledit mouvement de rotation et ledit mouvement axial décrits précédemment sont simultanés et provoque ledit vissage, selon un mouvement hélicoïdal. Ledit bouchon 9 est alors fixé par vissage audit goulot 7, alors qu'en position d'attente, préférentiellement, lesdits filetages 29 et 31 ne sont pas en prise.Advantageously, said neck 7 and said plug 9 each comprise a thread, said first thread 29 and second thread 31 cooperating together to allow the passage of said plug 9 from the waiting position to the position of use by screwing by the user of said cap 9 on the neck 7. In this embodiment said rotation movement and said axial movement described above are simultaneous and causes said screwing, in a helical movement. Said cap 9 is then fixed by screwing to said neck 7, while in the waiting position, preferably, said threads 29 and 31 are not engaged.

Ledit premier filetage 29 est situé sur la surface externe dudit goulot 7 dans une partie de celui-ci supérieure à l'anneau 25.Said first thread 29 is located on the outer surface of said neck 7 in a portion thereof greater than the ring 25.

Ledit second filetage 31 est situé sur la surface interne dudit bouchon 9 dans une partie de celui-ci supérieure auxdites excroissances 27a, 27b, ici en fond dudit bouchon 9.Said second thread 31 is located on the inner surface of said plug 9 in a portion thereof greater than said protuberances 27a, 27b, here at the bottom of said plug 9.

Ledit goulot 7 comprend en outre sur sa surface externe une zone lisse, dite première zone lisse 33. On entend, ici, par zone lisse une zone non-filetée. Ladite première zone lisse 33 s'étend sur une partie inférieure audit premier filetage 29 et inférieure audit anneau 25. Autrement dit, ladite première zone lisse 33 s'étend de la surface inférieure 25a dudit anneau 25 vers l'épaule 11 de la tête de tube 5. L'anneau 25 est ainsi axialement situé dans une partie médiane dudit goulot 7 entre ledit premier filetage 29 et ladite première zone lisse 33.Said neck 7 further comprises on its outer surface a smooth zone, said first smooth zone 33. Here, a smooth zone means a non-threaded zone. Said first smooth zone 33 extends on a lower portion to said first thread 29 and lower than said ring 25. In other words, said first smooth zone 33 extends from the lower surface 25a of said ring 25 towards the shoulder 11 of the head of the 5. The ring 25 is thus axially located in a median portion of said neck 7 between said first thread 29 and said first smooth zone 33.

Ledit bouchon 9 comprend également sur sa surface interne une zone lisse, dite seconde zone lisse 35. Là encore, on entend par zone lisse une zone non-filetée. Ladite seconde zone lisse 35 est située sur une partie inférieure audit second filetage 31 et supérieure aux excroissances 27a, 27b, c'est-à-dire entre les excroissances 27a, 27b et le second filetage 31. Dans l'exemple illustré, la seconde zone lisse 35 s'étend du bas du second filetage 31 jusqu'à la rangée supérieure d'excroissances 27b. Le diamètre interne dudit bouchon 9 au niveau de la seconde zone lisse 35 est supérieur au diamètre dudit goulot 7 mesuré au sommet du filets dudit premier filetage 29.Said cap 9 also comprises on its inner surface a smooth zone, called second smooth zone 35. Here again, smooth zone means a non-threaded zone. Said second smooth zone 35 is located on a lower part of said second thread 31 and greater than the protuberances 27a, 27b, that is to say between the protuberances 27a, 27b and the second threading 31. In the illustrated example, the second smooth zone 35 extends from the bottom of the second thread 31 to the upper row of excrescences 27b. The internal diameter of said plug 9 at the second smooth zone 35 is greater than the diameter of said neck 7 measured at the top of the threads of said first thread 29.

Ledit bouchon 9 comprend en outre une surface externe dont une partie, inférieure, est lisse 21 et l'autre partie, supérieure, nervurée 23. La partie nervurée 23 correspond notamment à une zone de préhension de l'utilisateur et facilite la prise en main du bouchon 9 et l'ouverture/fermeture dudit tube 3.Said cap 9 further comprises an outer surface of which a lower part is smooth 21 and the other part, upper, ribbed 23. The ribbed portion 23 corresponds in particular to a gripping area of the user and facilitates handling plug 9 and opening / closing said tube 3.

Dans un premier temps, ledit bouchon 9 est fixé sur ledit goulot 7. Dans cette étape, ledit anneau 25 est encliqueté sur la rangée inférieure d'excroissances 27a et le bouchon 9 est maintenu en position d'attente (figures 3 à 5). Le poinçon 17 est situé à une distance non nulle dudit opercule 15 pour le préserver d'une découpe et/ou perforation. Ici, ce maintien en position d'attente est assuré par la rangée supérieure d'excroissances 27b comme mentionné précédemment, sur laquelle l'anneau 25 vient en butée si on tente involontairement d'enfoncer le bouchon 9 (figure 5). La position de la rangée supérieure d'excroissances 27b est calculée de manière à ce que le poinçon 17 soit maintenu suffisamment éloigné dudit opercule 15 dans la position d'attente dudit bouchon 9. La rangée inférieure d'excroissances 27a, sur laquelle l'anneau 25 vient en butée si l'on tente involontairement de retirer le bouchon 9 (figure 4), permet d'éviter un retrait non désiré dudit bouchon 9.In a first step, said plug 9 is fixed on said neck 7. In this step, said ring 25 is snapped onto the lower row of protuberances 27a and the plug 9 is held in the waiting position ( Figures 3 to 5 ). The punch 17 is located at a non-zero distance from said lid 15 to preserve it from cutting and / or perforation. Here, this holding in the waiting position is provided by the upper row of excrescences 27b as mentioned above, on which the ring 25 comes into abutment if one tries to unintentionally push the plug 9 ( figure 5 ). The position of the upper row of excrescences 27b is calculated so that the punch 17 is kept sufficiently far from said cover 15 in the waiting position of said cap 9. The lower row of excrescences 27a, on which the ring 25 comes to a stop if one attempts unintentionally to remove the cap 9 ( figure 4 ), avoids unwanted withdrawal of said plug 9.

Dans cette position d'attente, ledit premier filetage 29 est situé en vis-à-vis de la seconde zone lisse 35 dudit bouchon 9, comme cela est visible aux figures 3 à 5. Les premier et second filetages (29, 31) ne coopèrent pas encore et le vissage du bouchon 9 sur le goulot 7 n'est pas encore entamé.In this standby position, said first thread 29 is located vis-à-vis the second smooth zone 35 of said plug 9, as can be seen in FIGS. Figures 3 to 5 . The first and second threads (29, 31) do not yet cooperate and the screwing of the plug 9 on the neck 7 is not yet started.

Dans un second temps, ledit bouchon 9 est enfoncé sur ledit goulot 7 par l'utilisateur selon l'axe Z-Z de manière à ce que ledit anneau 25 dépasse la rangée supérieure d'excroissances 27b pour arriver dans une position intermédiaire (figure 6). Dans cette position intermédiaire, le filetage 31 dudit bouchon 9 commence à s'engager dans le filetage 29 dudit goulot 7 et ledit poinçon 17 atteint puis perce et/ou découpe ledit opercule 15, sur le ou les derniers tours de vissage.In a second step, said cap 9 is pressed on said neck 7 by the user along the axis ZZ so that said ring 25 exceeds the upper row of excrescences 27b to reach an intermediate position ( figure 6 ). In this intermediate position, the thread 31 of said cap 9 begins to engage in the thread 29 of said neck 7 and said punch 17 reaches and then pierces and / or cuts said cap 15, on the last or the last screwing towers.

On peut également envisagé, dans un autre mode de réalisation non représenté, que lesdits filetages 29 et 31 sont au contact, voire en prise dès la position d'attente. Le vissage permet alors de faciliter le passage de la position d'attente à la position d'utilisation, et notamment le dépassement par ledit anneau de la rangée supérieure d'excroissances 27b, pour atteindre la position intermédiaire.It can also be envisaged, in another embodiment not shown, that said threads 29 and 31 are in contact, or even engaged from the waiting position. The screwing then makes it possible to facilitate the transition from the waiting position to the position of use, and in particular the passing by said ring of the upper row of excrescences 27b, to reach the intermediate position.

Pour finir, ledit bouchon 9 est complètement vissé sur ledit goulot 7 par l'utilisateur. Le bouchon 9 atteint ainsi la position de fermeture (figure 7) dans laquelle ledit opercule 15 est découpé et/ou perforé par ledit poinçon 17. La zone lisse 35 du bouchon 9 est alors en vis-à-vis de la zone lisse 33 dudit goulot 7.Finally, said cap 9 is completely screwed onto said neck 7 by the user. The plug 9 thus reaches the closed position ( figure 7 ) in which said lid 15 is cut and / or perforated by said punch 17. The smooth zone 35 of the plug 9 is then vis-à-vis the smooth zone 33 of said neck 7.

D'autres modes de réalisations sont envisageables permettant la fixation du bouchon sur le goulot et son maintien en position d'attente. Notamment, il est possible que l'anneau et les excroissances soient inversés, c'est-à-dire que le bouchon comprenne un anneau sur sa surface interne coopérant avec au moins une excroissance situées sur la surface externe du goulot.Other embodiments are possible for fixing the cap on the neck and its holding in the waiting position. In particular, it is possible that the ring and the excrescences are reversed, that is to say that the cap comprises a ring on its inner surface cooperating with at least one protrusion located on the outer surface of the neck.

Dans les modes de réalisation représentés aux figures 8 à 17, le ou lesdits premiers moyens de blocage sont un ou des éléments en saillie 37a, 37b, 37c situés sur une surface externe dudit goulot 7.In the embodiments shown in Figures 8 to 17 , said first locking means are one or more projecting elements 37a, 37b, 37c situated on an external surface of said neck 7.

Lesdits éléments en saillie 37a, 37b, 37c dudit goulot 7 sont configurés pour coopérer avec ledit bouchon 9 pour maintenir ledit bouchon 9 en position d'attente et plus particulièrement avec au moins un élément en saillie 39 dudit bouchon 9.Said protruding elements 37a, 37b, 37c of said neck 7 are configured to cooperate with said plug 9 to hold said plug 9 in the waiting position and more particularly with at least one projecting element 39 of said plug 9.

De façon avantageuse, ledit goulot 7 comprend également au moins une, ici trois, rainure 41 de guidage configurée pour coopérer avec ledit bouchon 9 pour permettre ledit mouvement de rotation et/ou ledit mouvement axiale pour le passage dudit bouchon 9 de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture.Advantageously, said neck 7 also comprises at least one, here three, guiding groove 41 configured to cooperate with said plug 9 to allow said rotational movement and / or said axial movement for the passage of said plug 9 from the position of waiting at the use position and / or the use position at the closed position.

Plus particulièrement, la rainure 41 de guidage dudit goulot 7 est configurée pour coopérer avec le ou chacun des éléments en saillie 39 dudit bouchon 9, notamment pour permettre ledit mouvement de rotation et/ou ledit mouvement axiale pour le passage dudit bouchon 9 de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture.More particularly, the groove 41 for guiding said neck 7 is configured to cooperate with the or each of the projecting elements 39 of said plug 9, in particular to allow said rotational movement and / or said axial movement for the passage of said plug 9 of the position waiting at the use position and / or the use position at the closed position.

Ainsi, ladite rainure 41 s'étend sur la surface externe dudit goulot 7 de l'extrémité supérieure du goulot 7 située à proximité de l'orifice de sortie 7a à l'extrémité inférieure opposée à ladite extrémité supérieure. Ladite rainure 41 comprend notamment une entrée 41 a située vers ledit orifice de sortie 7a dudit goulot 7.Thus, said groove 41 extends on the outer surface of said neck 7 of the upper end of the neck 7 located near the outlet port 7a at the lower end opposite said upper end. Said groove 41 comprises in particular an inlet 41a located towards said outlet orifice 7a of said neck 7.

De façon avantageuse, ladite rainure 41 présente des portions de guidage successives. Il peut s'agir notamment d'une première portion 41 b assurant la position d'attente et d'autres portions permettant le passage de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture.Advantageously, said groove 41 has successive guide portions. This may include a first portion 41b providing the waiting position and other portions allowing the passage from the waiting position to the position of use and / or the position of use to the closing position.

En particulier, ladite rainure 41 présente :

  • une seconde portion 41 c permettant de sortir ledit bouchon 9 de la position d'attente,
  • une troisième portion 41 d permettant le passage dudit bouchon 9 en position d'utilisation,
  • une dernière portion 41 e permettant le passage dudit bouchon 9 en position de fermeture.
In particular, said groove 41 has:
  • a second portion 41c for exiting said plug 9 from the waiting position,
  • a third portion 41 d allowing the passage of said plug 9 in the use position,
  • a last portion 41 e allowing the passage of said cap 9 in the closed position.

Ladite rainure 41 s'étend entre deux bords 55, s'étendant radialement depuis un fond 57 de ladite rainure 41. De préférence, ladite rainure 41 est issue de matière avec le goulot 7.Said groove 41 extends between two edges 55, extending radially from a bottom 57 of said groove 41. Preferably, said groove 41 is made of material with the neck 7.

Dans le mode de réalisation représenté à la figure 8, ladite première portion 41 b de ladite rainure 41 est verticale par rapport à l'axe Z-Z. Elle est suivie par la seconde portion 41 c qui est horizontale par rapport à l'axe Z-Z, puis par la troisième portion 41 d qui est verticale par rapport à l'axe Z-Z, et enfin par la dernière portion 41 e qui est horizontale par rapport à l'axe Z-Z.In the embodiment shown at figure 8 said first portion 41b of said groove 41 is vertical to the axis ZZ. It is followed by the second portion 41c which is horizontal with respect to the axis ZZ, then by the third portion 41d which is vertical with respect to the axis ZZ, and finally by the last portion 41e which is horizontal by relative to the ZZ axis.

Dans ce mode de réalisation, lesdits éléments en saillie 37a, 37b dudit goulot 7 sont des excroissances des bords de ladite rainure 41 s'étendant vers l'intérieur de la rainure. Alternativement, lesdits éléments en saillie 37a, 37b dudit goulot 7 peuvent être des excroissances issues du fond 57 de ladite rainure 41. Ainsi, ladite rainure 41 présente une première excroissance 37a située à l'entrée de la première portion 41b de la rainure 41. Cette première excroissance 37a limite le mouvement axial vers le haut selon l'axe Z-Z dudit bouchon 9 et permet de maintenir ledit bouchon 9 fixé sur ledit goulot 7 7 et d'éviter un retrait non désiré de celui-ci.In this embodiment, said projecting elements 37a, 37b of said neck 7 are protrusions of the edges of said groove 41 extending towards the inside of the groove. Alternatively, said protruding elements 37a, 37b of said neck 7 may be protrusions from the bottom 57 of said groove 41. Thus, said groove 41 has a first protrusion 37a located at the entrance of the first portion 41b of the groove 41. This first protrusion 37a limits the upward axial movement along the axis ZZ of said plug 9 and keeps said plug 9 fixed on said neck 7 7 and to avoid unwanted withdrawal thereof.

Ladite rainure 41 présente également une seconde excroissance 37b, de même nature, située entre la première 41b et la seconde 41 c portions de la rainure 41. Cette seconde excroissance 37b limite le mouvement en rotation dudit bouchon 9 et notamment la sortie du bouchon 9 de sa position d'attente et son engagement vers la position d'utilisation. Autrement dit, cette seconde excroissance 37b permet de maintenir le poinçon 17 éloigné de l'opercule 15 et d'éviter la perforation et/ou la découpe de celle-ci sans l'intervention de l'utilisateur avant la première utilisation.Said groove 41 also has a second protrusion 37b, of the same nature, located between the first 41b and the second 41c portions of the groove 41. This second protrusion 37b limits the rotational movement of said plug 9 and in particular the exit of the plug 9 of his waiting position and his commitment to the position of use. In other words, this second protrusion 37b keeps the punch 17 away from the lid 15 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.

Dans le mode de réalisation représenté à la figure 9, ladite première portion 41 b de ladite rainure 41 est verticale par rapport à l'axe Z-Z. Elle est suivie par la seconde portion 41 c qui est horizontale par rapport à l'axe Z-Z, puis par la troisième portion 41 d qui est hélicoïdale, et enfin par la dernière portion 41e qui est horizontale par rapport à l'axe Z-Z.In the embodiment shown at figure 9 said first portion 41b of said groove 41 is vertical to the axis ZZ. It is followed by the second portion 41c which is horizontal with respect to the ZZ axis, then by the third portion 41 d which is helical, and finally by the last portion 41e which is horizontal with respect to the axis ZZ.

Dans ce mode de réalisation, ledit goulot 7 comprend un premier élément en saillie qui est un premier ergot 37a située à l'entrée de la première portion 41 b de la rainure 41. Cet ergot 37a limite le mouvement axial vers le haut selon l'axe Z-Z dudit bouchon 9 et permet de maintenir ledit bouchon 9 fixé sur ledit goulot 7 et d'éviter un retrait non désiré dudit bouchon 9. Un des bords de ladite rainure 41 présente également une excroissance 37b qui est un second élément en saillie dudit goulot 7. Comme pour les excroissances 37a, 37b du mode de réalisation de la figure 8, la présente excroissance s'étend vers l'intérieur de la rainure 41. Cette excroissance 37b est située entre la première 41 b et la seconde 41 c portion de la rainure 41. Elle permet de limiter le mouvement en rotation dudit bouchon 9 et notamment la sortie du bouchon 9 de sa position d'attente et son engagement dans la position d'utilisation. Autrement dit, cette excroissance 37b permet de maintenir le poinçon 17 éloigné de l'opercule 15 et d'éviter la perforation et/ou la découpe de celle-ci sans l'intervention de l'utilisateur avant la première utilisation.In this embodiment, said neck 7 comprises a first projecting element which is a first lug 37a located at the entrance of the first portion 41b of the groove 41. This lug 37a limits the axial movement upwards according to the ZZ axis of said cap 9 and keeps said cap 9 fixed on said neck 7 and avoid undesired withdrawal of said cap 9. One edge of said groove 41 also has a protrusion 37b which is a second element projecting from said neck 7. As for the protuberances 37a, 37b of the embodiment of the figure 8 , the present protrusion extends inwardly of the groove 41. This protrusion 37b is located between the first 41b and the second 41c portion of the groove 41. It limits the rotational movement of said plug 9 and in particular the exit of the plug 9 from its standby position and its engagement in the position of use. In other words, this protrusion 37b keeps the punch 17 away from the lid 15 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.

Dans le mode de réalisation représenté aux figures 10 à 16 ladite première portion 41 b est verticale par rapport à l'axe Z-Z. Elle est suivit par la seconde portion 41 c qui est hélicoïdale de pente x, puis par la troisième portion 41 d qui est hélicoïdale de pente y. La pente y de la troisième portion hélicoïdale 41 d est supérieure à la pente x la deuxième portion hélicoïdale 41c. Ladite rainure 41 se termine enfin par la dernière portion 41 e qui est horizontale par rapport à l'axe Z-Z.In the embodiment shown in Figures 10 to 16 said first portion 41b is vertical with respect to the ZZ axis. It is followed by the second portion 41 c which is helical x slope, then by the third portion 41 d which is helical slope y. The slope y of the third helical portion 41d is greater than the slope x the second helical portion 41c. Said groove 41 finally ends with the last portion 41 e which is horizontal with respect to the axis ZZ.

Dans ce mode de réalisation, ledit goulot 7 comprend deux éléments en saillie sous la forme d'excroissances issues du fond de ladite rainure de guidage. Ces deux éléments en saille sont deux ergots 37a, 37b situées vers l'entrée 41a de ladite rainure 41. Plus particulièrement, un premier ergot 37a est situé à l'entrée de la première portion de la rainure 41. Cet ergot 37a limite le mouvement axial vers le haut selon l'axe Z-Z dudit bouchon 9 et permet de maintenir ledit bouchon 9 fixé sur ledit goulot 7 et d'éviter un retrait non désiré dudit bouchon 9. Le second ergot 37b est situé entre la première 41 b et la seconde 41 c portions de la rainure 41. Il permet de limiter le mouvement en rotation dudit bouchon 9 et notamment la sortie du bouchon 9 de sa position d'attente et son engagement vers la position d'utilisation. Autrement dit, ce second ergot 37b permet de maintenir le poinçon 17 éloigné de l'opercule 15 et d'éviter la perforation et/ou la découpe de celle-ci sans l'intervention de l'utilisateur avant la première utilisation.In this embodiment, said neck 7 comprises two projecting elements in the form of excrescences from the bottom of said guide groove. These two elements in groove are two lugs 37a, 37b located towards the entrance 41a of said groove 41. More particularly, a first lug 37a is located at the entrance of the first portion of the groove 41. This lug 37a limits the movement axial upwards along the axis ZZ of said plug 9 and keeps said plug 9 fixed on said neck 7 and to avoid unwanted withdrawal of said plug 9. The second pin 37b is located between the first 41b and the second 41 c portions of the groove 41. It limits the rotational movement of said plug 9 and in particular the output of the plug 9 from its standby position and its engagement to the position of use. In other words, this second lug 37b keeps the punch 17 remote from the lid 15 and to avoid the perforation and / or cutting thereof without the intervention of the user before the first use.

Dans le mode de réalisation représenté à la figure 17, ladite première portion 41 b est verticale par rapport à l'axe Z-Z. Elle est suivit par la seconde portion 41c qui est hélicoïdale de pente x, puis par la troisième portion 41 d qui est hélicoïdale de pente y. La pente y de la troisième portion hélicoïdale 41 d est supérieure à la pente x de la deuxième portion hélicoïdale 41c. Ladite rainure 41 se termine enfin par la dernière portion 41 e qui est horizontale par rapport à l'axe Z-Z.In the embodiment shown at figure 17 said first portion 41b is vertical with respect to the ZZ axis. It is followed by the second portion 41c which is helical x slope, then by the third portion 41 d which is helical slope y. The slope y of the third helical portion 41d is greater than the slope x of the second helical portion 41c. Said groove 41 finally ends with the last portion 41 e which is horizontal with respect to the axis ZZ.

Dans ce mode de réalisation, lesdits éléments en saillie dudit goulot 7 sont des excroissances 37a, 37b, 37c des bords de ladite rainure 41 s'étendant vers l'intérieur de la rainure. Ainsi, ladite rainure 41 présente une première excroissance 37a située à l'entrée de la première portion 41 b de la rainure 41. Cette première excroissance 37a limite le mouvement axial vers le haut selon l'axe Z-Z dudit bouchon 9 et permet de maintenir ledit bouchon 9 fixé sur ledit goulot 7 7 et d'éviter un retrait non désiré de celui-ci.In this embodiment, said elements projecting from said neck 7 are protuberances 37a, 37b, 37c of the edges of said groove 41 extending towards the inside of the groove. Thus, said groove 41 has a first protrusion 37a located at the inlet of the first portion 41b of the groove 41. This first protrusion 37a limits the upward axial movement along the axis ZZ of said plug 9 and allows to maintain said cap 9 attached to said neck 7 7 and to avoid unwanted withdrawal thereof.

Ladite rainure 41 présente également une seconde excroissance 37b, de même nature, située entre la première 41 b et la seconde 41 c portions de la rainure 41. Cette seconde excroissance 37b limite le mouvement en rotation dudit bouchon 9 et notamment la sortie du bouchon 9 de sa position d'attente et son engagement vers la position d'utilisation. Autrement dit, cette seconde excroissance 37b permet de maintenir le poinçon 17 éloigné de l'opercule 15 et d'éviter la perforation et/ou la découpe de celle-ci sans l'intervention de l'utilisateur avant la première utilisation.Said groove 41 also has a second protrusion 37b, of the same kind, located between the first 41b and the second 41c portions of the groove 41. This second protrusion 37b limits the rotational movement of said plug 9 and in particular the exit of the plug 9 from his waiting position and his commitment to the position of use. In other words, this second protrusion 37b keeps the punch 17 away from the lid 15 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.

Ladite rainure 41 présente, en outre, une troisième excroissance 37c, de même nature que les excroissances 37a et 37b, située sur le bord opposé à celui comprenant les excroissance 37a et 37b. Comme l'excroissance 37b, cette troisième excroissance 37c limite le mouvement en rotation dudit bouchon 9 et notamment la sortie du bouchon 9 de sa position d'attente et son engagement vers la position d'utilisation.Said groove 41 has, in addition, a third protrusion 37c, of the same nature as the protuberances 37a and 37b, located on the edge opposite to that comprising the protrusions 37a and 37b. Like the protrusion 37b, this third protrusion 37c limits the rotational movement of said plug 9 and in particular the exit of the plug 9 from its standby position and its engagement towards the position of use.

Dans ces quatre modes de réalisations représentés aux figures 8 à 17, ledit goulot 7 peut également comprendre une rampe de guidage 43 configurée pour coopérer avec au moins un élément en saillie 39 dudit bouchon 9 pour positionner un desdits éléments en saillie à l'entrée 41a de ladite rainure 41. La rampe de guidage 43 permet de guider un des éléments en saillie 39a du bouchon 9 dans la première portion 41 b de la rainure 41 de guidage. Ladite rampe de guidage 43 est visible à la figure 10.In these four embodiments represented in Figures 8 to 17 , said neck 7 may also comprise a guide ramp 43 configured to cooperate with at least one projecting element 39 of said plug 9 to position one of said projecting elements at the inlet 41a of said groove 41. The guide ramp 43 allows guide one of the projecting elements 39a of the plug 9 in the first portion 41b of the guide groove 41. Said guide ramp 43 is visible at the figure 10 .

De façon avantageuse, ladite rampe de guidage 43 présente une direction de guidage inverse à la direction de guidage de la dite rainure 41 pour le passage dudit bouchon 9 de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture. Ainsi, pour positionner un desdits éléments en saillie 39 dudit bouchon 9 dans l'entrée de ladite rainure 41, il est nécessaire de faire un mouvement de rotation dans un sens opposé à celui qui sera opéré dans la rainure. Ce mouvement de rotation est généralement réalisé par une machine de manière automatisée. Une fois ledit bouchon 9 mis en position d'attente, il est nécessaire de faire un mouvement de rotation dans un sens opposé à celui appliqué dans la rampe de guidage, généralement dans le sens de rotation classique de fermeture d'un bouchon 9 qui est généralement le sens des aiguilles d'une montre, ceci pour sortir le bouchon 9 de la position d'attente et amorcer la position d'utilisation et la découpe et/ou la perforation dudit opercule 15 par le poinçon 17. Ce double sens de rotation, permet d'éviter que la machine, lors de la mise en place du bouchon 9 en position d'attente, effectue une rotation trop importante, amorce un passage en position d'utilisation et que le poinçon 17 endommage l'opercule 15 avant l'utilisation du tube.Advantageously, said guide ramp 43 has a reverse guide direction to the guide direction of said groove 41 for the passage of said plug 9 from the waiting position to the use position and / or the position of use at the closed position. Thus, to position one of said projecting elements 39 of said plug 9 in the inlet of said groove 41, it is necessary to make a rotational movement in a direction opposite to that which will be operated in the groove. This rotational movement is generally performed by a machine in an automated manner. Once said plug 9 has been placed in the waiting position, it is necessary to make a rotational movement in a direction opposite to that applied in the guide ramp, generally in the conventional direction of rotation of closure of a plug 9 which is generally clockwise, this to remove the plug 9 from the standby position and initiate the use position and cutting and / or perforation of said lid 15 by the punch 17. This double direction of rotation , prevents the machine, when placing the plug 9 in the waiting position, makes too much rotation, initiates a passage in the use position and that the punch 17 damages the seal 15 before the use of the tube.

De façon avantageuse ladite rampe 43 peut également comprendre une butée 45 pour forcer l'arrêt d'un desdits éléments en saillie 39 du bouchon 9 au niveau de l'entrée 41 a de la rainure 41. Ici, la butée 45 est une prolongation d'un bord de la première portion 41 b de la rainure 41 en direction de l'orifice 7a du goulot 7.Advantageously, said ramp 43 may also comprise a stop 45 to force the stopping of one of said projecting elements 39 of the plug 9 at the inlet 41a of the groove 41. Here, the stop 45 is an extension of an edge of the first portion 41b of the groove 41 towards the orifice 7a of the neck 7.

Dans ces quatre modes de réalisations représentés aux figures 8 à 17, le bouchon 9 est identique. Comme mentionné précédemment, il comprend au moins un élément en saillie 39 configuré pour coopérer avec lesdits éléments en saillie 37a, 37b, 37c dudit goulot 7 pour maintenir ledit bouchon 9 en position d'attente et pour coopérer avec ladite rainure 41 dudit goulot 7 pour permettre ledit mouvement de rotation et/ou ledit mouvement axiale pour le passage dudit bouchon 9 de la position d'attente à la position d'utilisation et/ou de la position d'utilisation à la position de fermeture.In these four embodiments represented in Figures 8 to 17 , the plug 9 is identical. As mentioned above, it comprises at least one projecting element 39 configured to cooperate with said projecting elements 37a, 37b, 37c of said neck 7 to hold said plug 9 in the waiting position and to cooperate with said groove 41 of said neck 7 for allow said movement to rotation and / or said axial movement for the passage of said plug 9 from the waiting position to the use position and / or the use position to the closed position.

De façon avantageuse, ledit bouchon 9 comprend au moins deux éléments en saillie 39. De préférence, ledit bouchon 9 comprend trois éléments en saillie 39, ce qui permet d'équilibrer et stabiliser le bouchon 9 lorsqu'il est en position d'attente.Advantageously, said plug 9 comprises at least two projecting elements 39. Preferably, said plug 9 comprises three projecting elements 39, which makes it possible to balance and stabilize the plug 9 when it is in the standby position.

De façon avantageuse, le ou les éléments en saillie 39 dudit bouchon 9 sont situés sur la partie inférieure dudit bouchon 9 et sont issus de matière de celui-ci.Advantageously, the projecting element or elements 39 of said plug 9 are located on the lower part of said plug 9 and are derived from material thereof.

De façon avantageuse, une surface supérieure 47 dudit bouchon 9 présente au moins une ouverture 49 au droit des éléments en saillie 39 dudit bouchon 9. Ces ouvertures 49 servent notamment au moulage du bouchon 9 et plus particulièrement au moulage des éléments en saillie 39. Ainsi, le nombre d'ouvertures 49 est identique au nombre d'éléments en saillie 39 du dudit bouchon 9.Advantageously, an upper surface 47 of said plug 9 has at least one opening 49 in line with the projecting elements 39 of said plug 9. These openings 49 serve in particular for molding the plug 9 and more particularly for molding the projecting elements 39. , the number of openings 49 is identical to the number of projecting elements 39 of said plug 9.

Dans le bouchon 9 représenté ici, lesdits éléments en saillie du bouchon 9 sont des pions 39 de diamètre sensiblement similaire à la largeur des rainures 41 de guidage pour permettre aux pions 39 d'être guidés par celles-ci. Ici, le bouchon 9 comprend trois pions 39 régulièrement répartis sur la partie inférieure dudit bouchon 9 et trois ouvertures 49 sur sa surface supérieure 47 au droit des pions 39.In the plug 9 shown here, said elements projecting from the plug 9 are pins 39 of diameter substantially similar to the width of the guide grooves 41 to allow the pins 39 to be guided by them. Here, the plug 9 comprises three pins 39 regularly distributed over the lower part of said plug 9 and three openings 49 on its upper surface 47 to the right of the pins 39.

Pour assurer l'étanchéité du tube lorsque le bouchon 9 est en position de fermeture, ledit bouchon 9 comprend sur la face interne de sa surface supérieure une surépaisseur de matière correspondant à un jonc d'étanchéité 51 situé radialement en retrait desdites ouvertures 49. Ledit jonc d'étanchéité 51 est configuré pour coopérer avec un siège de jonc 53, prévue sur une surface intérieure du goulot, à l'extrémité supérieure dudit goulot 7, lorsque ledit bouchon 9 est en position de fermeture comme cela est visible sur la figure 16b.To ensure the tightness of the tube when the cap 9 is in the closed position, said plug 9 comprises on the inner face of its upper surface a material thickness corresponding to a sealing ring 51 located radially recessed from said openings 49. Said sealing ring 51 is configured to cooperate with a ring seat 53, provided on an inner surface of the neck, at the upper end of said neck 7, when said cap 9 is in the closed position as is visible on the figure 16b .

Les bords de ladite rainure 41 peuvent également comprendre au moins une excroissance située dans la dernière portion 41e permettant de maintenir le bouchon en position fermée.The edges of said groove 41 may also include at least one protrusion located in the last portion 41e for holding the cap in the closed position.

Par exemple, comme illustrée à la figure 17, chaque bord peut comprendre une excroissance 59a et 59b. Ces excroissances 59a, 59b permettent non seulement de maintenir le bouchon en position fermée, mais peuvent également servir de témoin de fermeture à l'utilisateur. Ainsi, la résistance ressentie par l'utilisateur lorsque les éléments en saillie 39 franchissent les deux excroissances 59a et 59b, permet de lui indiquer que le bouchon est en fin de course, que celui-ci est correctement fermé et que l'étanchéité est assurée. Ces caractéristiques sont ici représentées en liaison avec la figure 17 mais peuvent également être généralisées.For example, as illustrated in figure 17 each edge may comprise a protrusion 59a and 59b. These protuberances 59a, 59b not only keep the cap in the closed position, but can also serve as a closure indicator to the user. Thus, the resistance felt by the user when the protruding elements 39 cross the two protuberances 59a and 59b, allows to indicate that the cap is at the end of the race, that it is properly closed and that the seal is ensured. . These characteristics are represented here in connection with the figure 17 but can also be generalized.

Différentes étapes pour le placement du bouchon 9 dans sa position d'attente et pour son passage de la position d'attente à la position d'utilisation et de sa position d'utilisation à sa position de fermeture vont maintenant être décrites. Ces étapes se réfèrent au mode de réalisation de la rainure 41 représenté aux figures 10 à 16.Various steps for the placement of the plug 9 in its waiting position and for its passage from the waiting position to the position of use and its use position to its closed position will now be described. These steps refer to the embodiment of groove 41 shown in FIGS. Figures 10 to 16 .

Dans un premier temps, ledit bouchon 9 est fixé sur ledit goulot 7 dans sa position d'attente. Pour cela, les éléments en saillie 39a dudit bouchon 9 sont guidés dans la rampe de guidage 43 par un mouvement de rotation dans le sens inverse des aiguilles d'une montre. Cette étape est visible à la figure 13.In a first step, said cap 9 is fixed on said neck 7 in its waiting position. For this, the protruding elements 39a of said plug 9 are guided in the guide ramp 43 by a rotational movement in the opposite direction of clockwise. This step is visible at figure 13 .

Les éléments en saillie 39a du bouchon 9 sont alors placés dans l'entrée 41 a des rainures 41 correspondantes au niveau de leur première portion 41 b. Ils sont maintenus en butée vers la droite par la prolongation 45 de la première portion 41 b de la rainure 41 et vers le bas par le premier ergot 37a dudit goulot 7.The projecting elements 39a of the plug 9 are then placed in the inlet 41 has corresponding grooves 41 at their first portion 41b. They are held in abutment to the right by the extension 45 of the first portion 41b of the groove 41 and downwards by the first lug 37a of said neck 7.

Ledit bouchon 9 est ensuite placé dans sa position d'attente par un mouvement axial vers le bas, dans lequel chaque élément en saillie 39a engagé dans la rainure 41 est encliqueté au-delà du premier ergot 37a. Ledit bouchon 9 est alors maintenu dans la position d'attente par l'intermédiaire des premier 37a et deuxième 37b ergots qui limitent son déplacement vers la gauche (rotation) et vers le haut (translation) comme décrit précédemment. Cette position d'attente est visible aux figures 14a et 14b.Said plug 9 is then placed in its waiting position by an axial downward movement, in which each projecting element 39a engaged in the groove 41 is snapped beyond the first lug 37a. Said plug 9 is then held in the waiting position via the first 37a and second 37b lugs which limit its movement to the left (rotation) and upwards (translation) as described above. This waiting position is visible at Figures 14a and 14b .

Par un premier mouvement hélicoïdal, chaque élément en saillie 39a dudit bouchon 9 engagé dans la rainure 41 au niveau de la seconde portion 41 c est encliqueté au-delà du deuxième ergot 37b et le bouchon 9 sort de la position d'attente. Cette étape et visible aux figures 15a et 15b.By a first helical movement, each projecting element 39a of said plug 9 engaged in the groove 41 at the second portion 41c is snapped beyond the second lug 37b and the plug 9 out of the waiting position. This step and visible to Figures 15a and 15b .

Puis par un second mouvement hélicoïdal engendré par la troisième portion 41 d de la rainure 41, l'élément en saillie 39a passe dans la position d'utilisation dans laquelle l'opercule est perforé.Then by a second helical movement generated by the third portion 41 d of the groove 41, the projecting element 39a passes into the position of use in which the lid is perforated.

Le mouvement hélicoïdal se termine enfin lorsque chaque élément en saillie 39a engagé dans la rainure 41 atteint une position de butée située en fin de la dernière portion 41e de la rainure 41. Le bouchon 9 est alors dans la position de fermeture visible aux figures 16a e 16b.The helical movement finally ends when each projecting element 39a engaged in the groove 41 reaches a stop position located at the end of the last portion 41e of the groove 41. The cap 9 is then in the closed position visible to figures 16a e 16b .

Pour enlever ledit bouchon 9, l'utilisateur effectue les étapes dans le sens inverse.To remove said plug 9, the user performs the steps in the opposite direction.

Dans les autres modes de réalisation de la rainure de guidage 41 représentés aux figures 8, 9 et 17, les différentes étapes pour le placement du bouchon 9 dans sa position d'attente et pour son passage de la position d'attente à la position d'utilisation et de sa position d'utilisation à sa position de fermeture sont sensiblement similaires.In the other embodiments of the guide groove 41 shown in FIGS. Figures 8, 9 and 17 , the various steps for the placement of the plug 9 in its waiting position and for its passage from the waiting position to the position of use and its use position to its closed position are substantially similar.
