According to the invention, the seal 4 consists of a single piece of elastically deformable material, in the form of a frustum of a cone 5' closed by its minor base 6', the peripheral part of which partially covers the upper edge of the neck 1, its major base being open and laterally bordered by a hollow bead 7' forming a projection and connecting the frustum of a cone 5' to a portion in the form of a plane washer 9, while the minor base 6' is integral with a cylindrical stiffener 10' facing the washer 9. <IMAGE>

Description

Certains flacons, notamment des flacons de forme polyédrique, do'ivent être bouchés avec des bouchons de forme extérieure également polyédrique, soit correspondante, soit complémentaire, afin d'obtenir un certain résultat d'ordre esthétique dans ' l'aspect du flacon bouché. Pour conserver cet aspect, même lors d'un rebouchage du flacon, il faut donc indexer le bouchon dans sa position de fermeture. Cette indexation est relativement simple à réaliser lorsqu'il ne s'agit que de bouchons de parement ou de décoration, le bouchage et l'étanchéité du flacon étant réalisés par un dispositif séparé recouvert de ce bouchon de parement. Il n'en est pas de même lorsque le bouchon doit assurer lui-même cette étanchéité, et notamnent lorsqu'il s'agit de bouchons coopérant par filetage avec le goulot ou col du flacon.Some bottles, particularly bottles polyhedral shape, do 'ivent be clogged with outer shape of stoppers also polyhedral or corresponding or complementary to obtain a certain result aesthetic in' the appearance of the capped bottle. To maintain this appearance, even when the bottle is capped, the cap must be indexed in its closed position. This indexing is relatively simple to carry out when it is only facing or decoration plugs, the closure and sealing of the bottle being carried out by a separate device covered with this facing plug. It is not the same when the stopper itself has to ensure this tightness, and in particular when it comes to stoppers cooperating by threading with the neck or neck of the bottle.

Dans ce cas, on réalise l'indexation en plaçant sur le col et sur le bouchon des butées limitant le mouvement relatif de rotation des deux pièces en fin de vissage. Il faut que, dans cette position, le fond du bouchon prenne appui de manière étanche sur le bord supérieur du col, afin d'en réaliser l'obturation. A cet effet, il est connu d'utiliser des joints élastiquement déformables, placés entre le bord supérieur du goulot et le fond du bouchon, pour rendre sûre cette étanchéité, compte tenu des dispersions dimensionnelles existant entre le goulot et le bouchon, les tolérances de fabrication de ces éléments étant assez larges.In this case, the indexing is carried out by placing on the neck and on the stopper stops limiting the relative movement of rotation of the two parts at the end of screwing. It is necessary that, in this position, the bottom of the stopper bears sealingly on the upper edge of the neck, in order to close it. To this end, it is known to use elastically deformable seals, placed between the upper edge of the neck and the bottom of the cap, to make this seal secure, taking into account the dimensional dispersions existing between the neck and the cap, the tolerances of manufacture of these elements being quite wide.

Il est nécessaire, en outre, pour que le bouchage soit maintenu de manière satisfaisante, de "verrouiller" le bouchon dans sa position d'indexation. A cet effet, on connaît des dispositions complémentaires aux butées d'indexation consistant en un encliquetage d'éléments élastiques solidaires du bouchon sur des ergots portés par le col du flacon. Ces dispositions sont relativement complexes et nécessitent des outillages de fabrication également compliqués, notamment lorsqu'il s'agit de bouchons en matière plastique.In addition, in order for the closure to be satisfactorily maintained, it is necessary to "lock" the closure in its indexing position. To this end, additional arrangements are known to the indexing stops consisting of a snap-fastening of elastic elements secured to the stopper on lugs carried by the neck of the bottle. These arrangements are relatively complex and require equally complicated manufacturing tools, especially when it comes to plastic plugs.

L'invention entend proposer un dispositif nouveau, permettant d'assurer les deux fonctions d'étanchéité et de maintien du bouchon dans sa position de fermeture, ce, de manière simple avec des moyens faciles à fabriquer, notamment en très grande série.The invention intends to propose a new device, making it possible to ensure the two functions of sealing and of keeping the plug in its closed position, this in a simple manner with means that are easy to manufacture, in particular in very large series.

A cet effet elle a pour objet un bouchon fileté intérieurement à visser sur le filetage extérieur d'un gouloc de flacon, comportant des butées de fir de vissage coopérant avec des butées correspondantes prévues sur le goulot pour que, en position de fermeture, le bouchon soit toujours placé selon la même orientation angulaire par rapport au flacon, et comportant un joint déformable élastiquement, placé au droit d'une paroi de fond du bouchon et tourné vers la partie supérieure du goulot.For this purpose it relates to an internally threaded plug to be screwed onto the external thread of a bottle neck, comprising screwing firm stops cooperating with corresponding stops provided on the neck so that, in the closed position, the stopper is always placed in the same angular orientation with respect to the bottle, and comprising an elastically deformable seal, placed in line with a bottom wall of the cap and facing the upper part of the neck.

Selon l'une des caractéristiques principales de l'invention, le joint susdit est constitué d'une seule pièce en matériau déformable élastiquement, en forme de tronc de cône fermé par sa petite base, dont la partie périphérique vient en recouvrement partiel du bord supérieur du goulot, sa grande base étant ouverte et bordée latéralement par un bourrelet creux formant saillie surplombant la totalité du bord supérieur du goulot et reliant la base dudit tronc de cône à une partie en forme de rondelle plane parallèle à ladite petite base, tandis que cette petite base est solidaire d'un raidisseur cylindrique tourné en direction de ladite rondelle plane.According to one of the main features of the invention, the aforementioned seal consists of a single piece of elastically deformable material, in the form of a truncated cone closed by its small base, the peripheral part of which comes in partial covering of the upper edge. neck, its large base being open and bordered laterally by a hollow bead projecting overhanging the entire upper edge of the neck and connecting the base of said truncated cone to a portion in the form of a flat washer parallel to said small base, while this small base is integral with a cylindrical stiffener facing towards said flat washer.

Dans un mode préféré de réalisation de l'invention, la petite base susdite comporte une partie centrale en saillie axiale formant fût de centrage du joint à l'intérieur du goulot, tandis que le raidisseur cylindrique susdit est monté à coulissement dans un orifice central ménagé dans la paroi de fond susdite.In a preferred embodiment of the invention, the aforementioned small base has a central projecting axial portion forming a centering barrel of the joint inside the neck, while the above cylindrical stiffener is slidably mounted in a central orifice in the above bottom wall.

Avantageusement, la partie extrême dudit raidisseur, opposée à la petite base susdite, est de diamètre légèrement supérieur à celui dudit orifice central, de manière à, après introduction à force, constituer un moyen de retenue du joint sur le bouchon.Advantageously, the extreme part of said stiffener, opposite the aforementioned small base, is of diameter slightly greater than that of said central orifice, so as to, after forced introduction, constitute a means of retaining the seal on the plug.

En outre, ladite paroi de fond est adjacente à une surface cylindrique latérale, de diamètre sensiblement égal au diamètre extérieur du bourrelet susdit.In addition, said bottom wall is adjacent to a lateral cylindrical surface, of diameter substantially equal to the outside diameter of the aforementioned bead.

Enfin, dans un mode particulier de fabrication de l'invention, le bouchon est constitué par un canon fileté intérieurement et fermé par une paroi de fond pourvue d'un orifice central pour recevoir le raidisseur cylindrique susdit, ledit canon comportant, à côté de sa partie ouverte, une embase de forme extérieure polygonale, tandis que sa partie supérieure est équipée de pattes d'encliquetage,et par un capot évidé comportant intérieurement des surfaces d'appui pour recevoir lesdites pattes et ladite embase, le fond dudit évidement étant séparé de la paroi de fond du canon coiffé par le capot d'une distance permettant le libre coulissement du raidisseur cylindrique du joint.Finally, in a particular embodiment of the invention, the stopper is constituted by an internally threaded barrel and closed by a bottom wall provided with a central orifice for receiving the above-mentioned cylindrical stiffener, said barrel comprising, next to its open part, an external shaped base polygonal, while its upper part is fitted with latching lugs, and by a hollowed-out cover internally bearing surfaces for receiving said lugs and said base, the bottom of said recess being separated from the bottom wall of the barrel capped by the cover from a distance allowing the sliding of the cylindrical stiffener of the joint.

L'invention sera mieux comprise au cours de la descrip- tion donnée ci-après à titre d'exemple purement indicatif et non limitatif, qui permettra d'en dégager les avantages et les caractéristiques secondaires.The invention will be better understood during the description given below by way of purely indicative and nonlimiting example, which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés, dans lesquels :

  • - la figure 1 est une vue générale en coupe d'un mode de réalisation préféré d'un bouchon selon l'invention placé sur un flacon;
  • - les figures 2A et 2B illustrent un flacon pourvu de moyens d'indexation du bouchon; et
  • - les figures 3A, 3B et 3C montrent un canon porte- joint formant partie constitutive du bouchon illustré par la figure 1.
Reference will be made to the accompanying drawings, in which:
  • - Figure 1 is a general sectional view of a preferred embodiment of a stopper according to the invention placed on a bottle;
  • - Figures 2A and 2B illustrate a bottle provided with plug indexing means; and
  • FIGS. 3A, 3B and 3C show a seal carrier barrel forming a constituent part of the plug illustrated in FIG. 1.

Sur la figure 1, on voit un col ou goulot de récipient 1 pourvu d'un filetage extérieur la à simple ou double filet. Sur ce col, est vissé un bouchon 2 portant un filet intérieur 2a. Entre une paroi de fond 3 du bouchon 2 et le bord supérieur lb du goulot 1, on a disposé un joint élastiquement déformable représenté en 4 écrasé entre la paroi 3 et le bord lb sur la partie de gauche de la figure 1 et en 4' à l'état libre sur la partie de droite de la figure.In Figure 1, we see a container neck or neck 1 provided with an external thread la single or double thread. On this neck is screwed a plug 2 carrying an internal thread 2a. Between an end wall 3 of the plug 2 and the upper edge 1b of the neck 1, an elastically deformable seal shown in 4 crushed between the wall 3 and the edge 1b has been placed on the left-hand side of FIG. 1 and in 4 ' in the free state on the right part of the figure.

Ce joint est constitué, à l'état libre, en une seule pièce par une partie tronconique 5', dont la petite base est fermée par une capsule 6', ici présentant une partie en saillie axiale 6a' pour constituer un fût de centrage du joint dans le goulot. Dans un autre mode de réalisation non représenté, on peut prévoir ladite partie 6' plane. On remarque, sur la figure, que cette petite base 6' vient en recouvrement par sa partie périphérique d'une par- . tie intérieure du bord supérieur 1b' du goulot. La grande base du tronc de cône 5' est,

Figure imgb0001
prolongée par un bourelet extérieur creux 7', de forme sensiblement torique, qui fait saillie vers l'extérieur, de manière à surplomber le bord 1b' du goulot et à venir sensiblement au concact, même à l'état libre, d'une surface cylindrique latérale 8 interne au bouchon 2 et adjacente à la paroi du fond 3. Enfin, ledit bourrelet est raccordé à une partie annulaire 9 sensiblement plane, formant rondelle, pour l'appui du joint sur la paroi de fond 3 du bouchon.This seal is constituted, in the free state, in a single piece by a frustoconical part 5 ', the small base of which is closed by a capsule 6', here having an axial projecting part 6a 'to constitute a centering barrel of the seal in the neck. In another embodiment not shown, one can provide said flat portion 6 '. Note in the figure, that this small base 6 'overlaps by its peripheral part of a. inner tie of the upper edge 1b 'of the neck. The great base of trunk of cone 5 'east,
Figure imgb0001
extended by a hollow external bead 7 ′, of substantially toroidal shape, which projects outwards, so as to overhang the edge 1b ′ of the neck and to come substantially in contact, even in the free state, with a surface lateral cylindrical 8 internal to the plug 2 and adjacent to the bottom wall 3. Finally, said bead is connected to an annular part 9 which is substantially flat, forming a washer, for pressing the seal on the bottom wall 3 of the plug.

La base 6' ou, plus précisément, sa partie saillante 6a' est solidaire d'un raidisseur cylindrique creux 10, 10' qui lui est sensiblement perpendiculaire. Ainsi, lors du serrage du bouchon 2 sur le goulot 3, le joint passe de sa position représentée en trait mixte 4'(partie de gauche de la figure 1) à sa position représentée en trait plein 4 (partie de droite de la figure 1) en subissant une déformation. Les éléments déjà décrits portent les mêmes références sans l'accent " ' ".The base 6 'or, more precisely, its projecting part 6a' is integral with a hollow cylindrical stiffener 10, 10 'which is substantially perpendicular to it. Thus, when the plug 2 is tightened on the neck 3, the seal passes from its position shown in phantom 4 '(left part of Figure 1) to its position shown in solid line 4 (right part of Figure 1 ) by undergoing a deformation. The elements already described have the same references without the accent "'".

Cette déformation se produit de la manière suivante. Le tronc de cône 5' tend à repousser vers le haut et vers l'extérieur le bourrelet 7' pour le placer dans sa configuration 7 dans laquelle il se plaque sur la surface cylindrique latérale 8. En outre, ledit tronc de cône 5' s'incurve vers l'extérieur et vers le bas, tendant ainsi à arc-bouter le joint entre le bord lb du goulot et la paroi 3.This deformation occurs in the following manner. The truncated cone 5 'tends to push upward and outward the bead 7' to place it in its configuration 7 in which it is pressed onto the lateral cylindrical surface 8. Furthermore, said truncated cone 5 's curved outward and downward, thus tending to brace the joint between the edge 1b of the neck and the wall 3.

L'action de serrage a également tendance à faire échapper la partie de petite base 6' du bord supérieur du goulot vers l'intérieur de ce goulot, mais le raidisseur cylindrique 10 rigidifie ladite petite base (ou sa saillie axiale 6a') qui résiste à cette tendance et maintient le contact de 6' sur le bord lb.The tightening action also tends to make the small base part 6 'escape from the upper edge of the neck towards the inside of this neck, but the cylindrical stiffener 10 stiffens said small base (or its axial projection 6a') which resists to this tendency and maintains the contact of 6 'on the edge lb.

On voit que les dispositions du joint ci-dessus décrit permettent, d'une part, d'assurer l'étanchéité de la fermeture entre la paroi 3 et le bord 1b et, d'autre part, par frottement sur la surface 8, de créer une force de freinage du bouchon vissé sur le goulot s'opposant au dévissage intempestif de ce dernier.It can be seen that the arrangements of the seal described above make it possible, on the one hand, to seal the closure between the wall 3 and the edge 1b and, on the other hand, by friction on the surface 8, to create a braking force of the screwed cap on the neck opposing the untimely unscrewing of the latter.

Par ailleurs, il est à remarquer que le raidisseur 10 se prolonge en direction de la paroi 3 qu'il traverse à coulissement dans une ouverture 3a dont elle est pourvue et que, au-delà de cette ouverture, le raidisseur possède une partie 10a-10a' de diamètre extérieur plus important que le diamètre de l'ouverture 3a.Furthermore, it should be noted that the stiffener 10 is extended in the direction of the wall 3 which it slides through in an opening 3a with which it is provided and that, beyond of this opening, the stiffener has a portion 10a-10a 'of outside diameter larger than the diameter of the opening 3a.

Cette partie 10a, forcée dans l'ouverture 3a au moment du montage, constitue un organe de retenue du joint 4 sur le bouchon 2. Ainsi, le raidisseur 10, qui coulisse dans l'orifice 3a, . constitue un guide pour le joint lors de sa déformation qui assure la constance de l'orientation de la petite base 6' (ou de sa saillie 6a'), augmentant la qualité du contact de sa partie périphérique avec le bord supérieur du goulot..This part 10a, forced into the opening 3a at the time of assembly, constitutes a member for retaining the seal 4 on the plug 2. Thus, the stiffener 10, which slides in the orifice 3a,. constitutes a guide for the joint during its deformation which ensures the consistency of the orientation of the small base 6 ′ (or of its projection 6a ′), increasing the quality of the contact of its peripheral part with the upper edge of the neck.

Sur les figures 2A et 2B, on a représenté un récipient parallélépipédique pourvu d'un col 1 portant un filetage la à deux filets. A la base de ce filetage, des ergots lla et llb constituent des butées d'arrêt en rotation du bouchon en fin de vissage.In FIGS. 2A and 2B, there is shown a rectangular container provided with a neck 1 carrying a thread la with two threads. At the base of this thread, lugs 11a and 11b constitute stops for rotating the stopper at the end of screwing.

En regard maintenant des figures 1 et 3A, 3B, 3C, on voit que le bouchon 2 est constitué d'un canon interne 12 pourvu du filetage intérieur 2a de la paroi 3, avec son orifice 3a, et de la surface cylindrique 8. Ce canon comporte, à sa partie inférieure, une embase 12a polygonale (ici carrée) porteuse intérieurement de butées telles que 13 susceptibles de coopérer avec les butées lla et 11b susdites.Now looking at Figures 1 and 3A, 3B, 3C, we see that the plug 2 consists of an internal barrel 12 provided with the internal thread 2a of the wall 3, with its orifice 3a, and the cylindrical surface 8. This barrel comprises, at its lower part, a polygonal base 12a (here square) internally carrying stops such as 13 capable of cooperating with the abovementioned stops 11a and 11b.

A sa partie supérieure, le canon 12 est pourvu de quatre pattes d'encliquetage 12b légèrement élastiques. Un capot 14 (figure 1) est évidé intérieurement, de manière à recevoir le canon 12 dans une position relative déterminée (par exemple par une forme complémentaire de celle de l'embase carrée), ledit canon étant maintenu dans le capot 14 au moyen des pattes d'encliquetage 12b et de l'embase 12a prenant appui sur des surfaces ménagées à cet effet dans ledit évidement.At its upper part, the barrel 12 is provided with four slightly elastic snap tabs 12b. A cover 14 (FIG. 1) is hollowed out internally, so as to receive the barrel 12 in a determined relative position (for example by a shape complementary to that of the square base), said barrel being held in the cover 14 by means of the latching lugs 12b and the base 12a bearing on surfaces provided for this purpose in said recess.

La position axiale du canon 12 dans le capot 14 sera telle qu'un espace 15 sera laissé libre entre la paroi 3 du canon et le fond 14a du capot 14 pour le logement et le coulissement libre du raidisseur 10 dans l'orifice 3a pendant au moins une partie du vissage du bouchon.The axial position of the barrel 12 in the cover 14 will be such that a space 15 will be left free between the wall 3 of the barrel and the bottom 14a of the cover 14 for housing and the free sliding of the stiffener 10 in the orifice 3a during the minus part of the screwing of the cap.

En effet, on peut prévoir que cette distance soit plus courte que la déformation envisagée du joint, donc que le coulissement total du raidisseur 10 dans l'orifice 3a. Ainsi, en fin de vissage; le fond 14a du capee 24 poussera le raidisseur 10, ce que sura pour effet, par l'irtermédiaire de la partie 6a, 6a', de plaquer la base 6, 6' plus énergiquement sur le bord 1b du goulot, voire de forcer partiellement la pénétration du tronc de cône 5 dans ledit goulot.Indeed, it can be expected that this distance is shorter than the envisaged deformation of the joint, therefore that the total sliding of the stiffener 10 in the orifice 3a. So at the end of screwing; the bottom 14a of the capee 24 will push the stiffener 10, which will have the effect, by means of the part 6a, 6a ', of pressing the base 6, 6' more energetically on the edge 1b of the neck, or even of partially forcing the penetration of the truncated cone 5 into said neck.

L'invention n'est pas limitée à la description qui vient d'en être donnée, mais couvre, au contraire, toutes les variantes qui pourraient lui être apportées sans sortir de son cadre ni de son esprit.The invention is not limited to the description which has just been given, but covers, on the contrary, all the variants which could be made to it without departing from its scope or its spirit.

Elle trouve une application intéressante dans l'industrie des emballages et, notamment, des flacons de parfumerie.It finds an interesting application in the packaging industry and, in particular, in perfume bottles.
