Description

La présente invention a pour objet un dispositif de fermeture pour une boíte de boisson, notamment de boisson gazeuse, du type comportant une paroi latérale cylindrique fermée à sa base par un fond et à sa partie supérieure par un couvercle inamovible qui est pourvu d'un opercule au moins partiellement séparable et d'un rebord périphérique et qui est raccordé, depuis sa périphérie, à l'extrémité supérieure de ladite paroi latérale par une partie évasée radialement vers l'extérieur.The present invention relates to a closure device for a box of drink, especially carbonated drink, of the type having a side wall cylindrical closed at its base by a bottom and at its upper part by a cover irremovable which is provided with an at least partially separable cover and a rim peripheral and which is connected, from its periphery, to the upper end of said side wall by a portion flared radially outwards.

Tout utilisateur d'une telle boíte de boisson, en particulier d'une boíte dont l'opercule est enlevé par déchirement, qui n'a pas consommé la totalité de son contenu, a un jour ou l'autre souhaité refermer cette boíte de manière étanche pour éviter la perte du liquide restant par suite du renversement de la boíte et/ou pour conserver à la boisson toutes ses propriétés et ses qualités.Any user of such a beverage can, in particular a can of which the cover is removed by tearing, which has not consumed all of its content, one day or another wished to close this box tightly to avoid loss of the liquid remaining due to the overturning of the box and / or to keep the drink all its properties and qualities.

Conscients de ce souhait, certains fabricants ont mis au point des dispositifs de fermeture adaptés à de telles boítes. Ces dispositifs comprennent généralement

  • (a) une coiffe formée d'une part, d'un élément supérieur pourvu d'un orifice et d'un goulot obturable faisant saillie au-dessus de cet élément à partir de cet orifice et d'autre part, d'une jupe périphérique élastiquement déformable, compressible et muni d'un premier logement annulaire destiné à recevoir le rebord de la boíte et d'une première surface d'appui continue s'étendant sur le pourtour interne de ladite jupe, et
  • (b) des moyens de pression de ladite première surface d'appui contre la paroi latérale ou la partie évasée de ladite boíte.
    • Aware of this wish, some manufacturers have developed closing devices suitable for such boxes. These devices generally include
  • (a) a cap formed on the one hand, of an upper element provided with an orifice and a closable neck protruding above this element from this orifice and on the other hand, of a skirt elastically deformable, compressible peripheral and provided with a first annular housing intended to receive the edge of the box and with a first continuous bearing surface extending on the internal periphery of said skirt, and
  • (b) pressure means of said first bearing surface against the side wall or the flared part of said box.

    • Il apparaít cependant qu'avec ces dispositifs connus, il est difficile d'obtenir une parfaite étanchéité notamment quand les boítes en cause contiennent des boisons gazeuses qui, même lorsqu'elles sont légèrement secouées, libèrent un gaz s'échappant du dispositif de fermeture sous l'effet de sa pression ; de plus, certains de ces dispositifs connus ne sont utilisables qu'une seule fois du fait qu'ils sont indémontables.It appears however that with these known devices, it is difficult to obtain a perfect watertightness especially when the boxes in question contain drinks which, even when slightly shaken, release escaping gas the closing device under the effect of its pressure; in addition, some of these devices known can only be used once because they cannot be dismantled.

    Le but de la présente invention réside donc dans la mise au point d'un dispositif de conception simple, adaptable facilement sur une boíte de boisson à opercule non réutilisable, assurant une fermeture étanche de la boíte une fois son opercule enlevé et qui est par ailleurs pourvu de moyens facilitant la consommation de la boisson.The object of the present invention therefore lies in the development of a device simple design, easily adaptable to a non-sealed beverage can reusable, ensuring a watertight closure of the box once its cover removed and which is also provided with means facilitating the consumption of the drink.

    A cet effet, la présente invention propose un dispositif de fermeture qui comprend les moyens (a) et (b) ci-dessus et qui se caractérise en ce que lesdits moyens de pression comprennent une bague de serrage concentrique avec ladite jupe périphérique autour de l'axe de symétrie de la boíte, ladite bague de serrage ayant une première face intérieure constituée par au moins une surface cylindrique excentrée par rapport audit axe de symétrie et coopérant avec une surface cylindrique correspondante définissant une face extérieur de la jupe périphérique.To this end, the present invention provides a closure device which comprises the means (a) and (b) above and which is characterized in that said means of pressure include a concentric clamping ring with said peripheral skirt around the axis of symmetry of the box, said clamping ring having a first face inner consisting of at least one cylindrical surface eccentric with respect to said axis of symmetry and cooperating with a corresponding cylindrical surface defining a outer face of the peripheral skirt.

    On comprendra aisément qu'en entraínant ladite bague de serrage en rotation, la coiffe étant quant à elle maintenue immobilisée, cette bague va sous l'effet du déplacement relatif des surfaces cylindriques excentrées provoquer une pression de la jupe périphérique de la coiffe contre la boíte de boisson ; dans la mesure où cette jupe est en un matériau élastiquement déformable et compressible, celle-ci va réaliser l'étanchéité recherchée.We can easily understand that by driving said clamping ring in rotation, the cap being kept immobilized, this ring goes under the effect of relative displacement of the eccentric cylindrical surfaces causing pressure from the peripheral skirt of the cap against the beverage can; as far as this skirt is made of an elastically deformable and compressible material, this will the required seal.

    Il est à noter qu'en vue de l'immobilisation en rotation de la coiffe, le dispositif selon l'invention comprend avantageusement des moyens de blocage pour empêcher toute rotation de ladite coiffe par rapport à la boíte.It should be noted that for the purpose of immobilizing the cap in rotation, the device according to the invention advantageously comprises blocking means to prevent any rotation of said cap relative to the box.

    Ces moyens de blocage peuvent tout simplement comprendre une excroissance prenant naissance sur l'élément supérieur de la coiffe et s'étendant au-dessous de cet élément sur une longueur suffisante pour pouvoir pénétrer dans l'orifice qui se trouve formé dans le couvercle de la boíte après enlèvement dudit opercule amovible.These blocking means may simply include a protuberance arising on the upper element of the cap and extending below this element over a sufficient length to be able to penetrate the orifice which is formed in the cover of the box after removal of said removable cover.

    Par ailleurs, selon une forme de réalisation du dispositif selon l'invention, la jupe périphérique de la coiffe comprend au moins un logement annulaire supplémentaire décalé axialement et radialement par rapport au premier logement et destiné à recevoir le rebord d'une boíte de boisson de diamètre différent de celui de la boíte dont le rebord est destiné à être reçu dans le premier logement.Furthermore, according to one embodiment of the device according to the invention, the skirt cap peripheral includes at least one additional annular housing axially and radially offset from the first housing and intended to receive the rim of a beverage can of different diameter than that of the can whose rim is intended to be received in the first accommodation.

    Grâce à cette disposition, il est ainsi possible d'utiliser le dispositif selon l'invention sur la plupart des boítes de boisson disponibles sur le marché, puisqu'à l'heure actuelle, il en existe essentiellement de deux diamètres différents.Thanks to this arrangement, it is thus possible to use the device according to the invention on most beverage cans available on the market, since At present, there are essentially two different diameters.

    D'autre part, selon une autre forme de réalisation du dispositif selon l'invention, la jupe périphérique comprend au moins une surface d'appui continu supplémentaire axialement et radialement décalée par rapport à la première surface d'appui et la bague de serrage comporte au moins une face intérieure supplémentaire axialement et radialement décalée par rapport à la première face intérieure et constituée par au moins une surface cylindrique excentrée par rapport à l'axe de symétrie de la base et coopérant avec une surface cylindrique correspondante définissant une autre face extérieure de la jupe périphérique.On the other hand, according to another embodiment of the device according to the invention, the peripheral skirt comprises at least one additional continuous bearing surface axially and radially offset from the first bearing surface and the ring clamping device has at least one additional inner face axially and radially offset from the first inner face and consisting of at least a cylindrical surface eccentric with respect to the axis of symmetry of the base and cooperating with a corresponding cylindrical surface defining another external face of the peripheral skirt.

    On notera que chaque face intérieure de la bague de serrage est de préférence constituée par plusieurs surfaces cylindriques successives qui se rejoignent et excentrées chacune par rapport à l'axe de symétrie de la boíte, ces surfaces ayant la même longueur angulaire, ce qui assure un serrage rapide et uniforme.Note that each inner face of the clamping ring is preferably constituted by several successive cylindrical surfaces which meet and eccentric each relative to the axis of symmetry of the box, these surfaces having the same length angular, which ensures rapid and uniform tightening.

    On notera également que chaque surface d'appui est de préférence sensiblement parallèle à la partie évasée de la boíte et disposée pour être en regard de cette partie évasée.It will also be noted that each bearing surface is preferably substantially parallel to the flared part of the box and arranged to be opposite this part flared.

    Il est en outre avantageux que l'élément supérieur de la coiffe présente une gorge concentrique au voisinage de sa périphérie ; cette gorge a pour but d'enlever de la rigidité à cet élément supérieur et donc de faciliter la mise en place du dispositif sur la boíte.It is also advantageous for the upper element of the cap to have a groove concentric in the vicinity of its periphery; the purpose of this groove is to remove rigidity to this upper element and therefore facilitate the installation of the device on the box.

    Selon une autre variante encore du dispositif selon l'invention, chaque logement comporte une surface d'appui s'étendant sur tout son pourtour interne et qui, sous l'effet desdits moyens de pression, vient s'appliquer contre la face intérieure du rebord de la boíte ; cette mesure améliore encore, s'il en était besoin, l'étanchéité du dispositif.According to yet another variant of the device according to the invention, each housing has a bearing surface extending over its entire internal periphery and which, under the effect said pressure means, is applied against the inner face of the rim of the box ; this measure further improves, if necessary, the sealing of the device.

    Enfin, ce dispositif peut en outre avantageusement comporter des moyens d'accrochage aptes à venir prendre appui élastiquement sur la paroi latérale de la boíte.Finally, this device can also advantageously include means attachment capable of coming to bear elastically on the side wall of the box.

    Grâce à ces moyens, l'ensemble dispositif-boíte de boisson peut être facilement accroché à tout support disponible tel que sac ou ceinture, ce qui en rend très aisé son transport.Thanks to these means, the device-drink can assembly can be easily attached to any available support such as bag or belt, making it very easy transport.

    Ces moyens d'accrochage comprennent de préférence une patte s'étendant axialement et solidaire de la bague de serrage.These attachment means preferably comprise a tab extending axially and integral with the clamping ring.

    Le dispositif selon l'invention est destiné à réaliser la fermeture notamment d'une boíte de boisson telle que représentée sur la figure 1. Cette boíte est formée d'un corps métallique habituellement en aluminium, qui comporte une paroi latérale 1 généralement cylindrique, fermée par un fond 2 et par un couvercle 3 légèrement bombé. Ce dernier est pourvu d'un opercule déchirable 4 de forme sensiblement circulaire initialement fermé, mais qui peut aisément être enlevé en soulevant une languette 5 qui agit comme un levier pour déchirer ledit opercule 4 et ainsi dégager un orifice pour l'écoulement de la boisson.The device according to the invention is intended to achieve the closure in particular of a beverage can as shown in Figure 1. This can is formed by a body metallic usually aluminum, which generally has a side wall 1 cylindrical, closed by a bottom 2 and by a slightly domed cover 3. This last is provided with a tear-off lid 4 of substantially circular shape initially closed, but which can easily be removed by lifting a tab 5 which acts as a lever for tearing said cover 4 and thus clearing an orifice for the flow of the beverage.

    Le couvercle 3 est par ailleurs pourvu, le long de sa périphérie, d'un rebord 6 saillant au-dessus dudit couvercle. Ce rebord 6, qui comporte une lèvre annulaire extérieure 7, résulte du sertissage d'une zone périphérique dudit couvercle 3 avec l'extrémité supérieure de la paroi latérale 1, cette opération de sertissage ayant pour effet de donner à la partie haute de la paroi latérale 1 la forme d'une zone 8 évasée radialement vers l'extérieur depuis la périphérie du couvercle.The cover 3 is also provided, along its periphery, with a flange 6 protruding above said cover. This rim 6, which has an annular lip outer 7, results from the crimping of a peripheral zone of said cover 3 with the upper end of the side wall 1, this crimping operation having the effect to give the upper part of the side wall 1 the shape of a flared zone 8 radially outward from the periphery of the cover.

    Par ailleurs, le dispositif selon l'invention comprend de manière connue en soi une coiffe 9 formée d'une plaque supérieure 10 et d'une jupe périphérique 11 et des moyens de pression de ladite jupe contre la boíte.Furthermore, the device according to the invention comprises, in a manner known per se, a cap 9 formed by an upper plate 10 and a peripheral skirt 11 and means pressure of said skirt against the box.

    La plaque 10 est de forme circulaire et son diamètre est sensiblement égal à celui du couvercle 3. En outre, elle est pourvue d'un perçage circulaire 12 positionné pour venir sensiblement en regard de l'orifice destiné à être formé par enlèvement de l'opercule 4. Ce perçage 12 est prolongé à sa périphérie par un goulot 13 s'étendant verticalement au-dessus de la plaque 10, le bord libre de ce goulot étant de forme arrondie. On ajoutera que ce goulot 13 est pourvu sur sa surface interne d'un filet 14 ; ce dernier est destiné à coopérer avec un sillon en hélice creusé dans la partie cylindrique 15 d'un bouchon 16 destiné à être vissé de manière hermétique dans ledit goulot 13.The plate 10 is circular in shape and its diameter is substantially equal to that of the cover 3. In addition, it is provided with a circular bore 12 positioned for come substantially opposite the orifice intended to be formed by removal of the cover 4. This bore 12 is extended at its periphery by a neck 13 extending vertically above the plate 10, the free edge of this neck being shaped rounded. It will be added that this neck 13 is provided on its internal surface with a thread 14; the latter is intended to cooperate with a helical groove dug in the part cylindrical 15 of a plug 16 intended to be hermetically screwed into said neck 13.

    Pour immobiliser la plaque 10 en rotation, celle-ci est en outre pourvue d'une excroissance 17 sur sa face inférieure et conformée pour s'engager dans l'orifice destiné à être formé dans le couvercle 3 par déchirement de l'opercule 4.To immobilize the plate 10 in rotation, it is further provided with a protuberance 17 on its underside and shaped to engage in the orifice intended to be formed in the cover 3 by tearing the cover 4.

    La jupe périphérique 11 de la coiffe 9 comporte du côté de sa face interne un premier logement annulaire 18 conformé pour recevoir l'extrémité supérieure (y compris la lèvre 7) du rebord 6 de la boíte et, axialement au-dessous de ce logement 18, une première surface d'appui 19 s'étendant sur tout le pourtour de la jupe.The peripheral skirt 11 of the cap 9 has on the side of its internal face a first annular housing 18 shaped to receive the upper end (including the lip 7) of the rim 6 of the box and, axially below this housing 18, a first bearing surface 19 extending over the entire periphery of the skirt.

    Conformément à l'invention, la jupe comprend, également du côté de sa face interne, un logement annulaire supplémentaire 20 situé au-dessous du logement 18 en étant décalé axialement et radialement par rapport à ce dernier ; en outre, ladite jupe comprend, axialement au-dessous du logement 20, une surface d'appui supplémentaire 21 s'étendant sur tout le pourtour de la face interne de la jupe.According to the invention, the skirt comprises, also on the side of its face internal, an additional annular housing 20 located below the housing 18 in being offset axially and radially with respect to the latter; in addition, said skirt comprises, axially below the housing 20, an additional bearing surface 21 extending over the entire periphery of the internal face of the skirt.

    On notera que le logement supplémentaire 20 est lui aussi conformé pour recevoir l'extrémité supérieure (y compris la lèvre 7) du rebord 6 d'une boíte, le diamètre de cette dernière étant supérieur à celui de la boíte dont le rebord 6 est destiné à venir se loger dans le logement 18.Note that the additional housing 20 is also shaped to receive the upper end (including the lip 7) of the rim 6 of a box, the diameter of this last being greater than that of the box whose rim 6 is intended to be housed in housing 18.

    On notera également que la face interne du logement 18 destinée à coopérer avec la lèvre 7 du rebord 6, est raccordée à la première surface d'appui 19 par un épaulement radial 22 apte à venir s'encastrer sous la lèvre 7 ; il en est de même de la face interne du logement 20 destiné à coopérer avec la lèvre 7, qui est raccordée à la surface d'appui 21 par un épaulement radial 23 apte également à venir s'encastrer sous la lèvre 7 du rebord 6.It will also be noted that the internal face of the housing 18 intended to cooperate with the lip 7 of the rim 6, is connected to the first bearing surface 19 by a shoulder radial 22 able to be fitted under the lip 7; the same is true of the internal face of the housing 20 intended to cooperate with the lip 7, which is connected to the bearing surface 21 by a radial shoulder 23 also capable of being fitted under the lip 7 of the ledge 6.

    La coiffe 9 est en une matière élastiquement déformable et compressible, telle que par exemple du polyéthylène haute densité. Afin d'enlever de la rigidité à la plaque 10, celle-ci est avantageusement pourvue d'une gorge concentrique 24 au voisinage de sa périphérie, cette gorge facilitant, comme on le verra ci-après, la mise en place du dispositif de l'invention sur le rebord de la boíte.The cap 9 is made of an elastically deformable and compressible material, such as for example high density polyethylene. In order to remove rigidity from plate 10, it is advantageously provided with a concentric groove 24 in the vicinity of its periphery, this groove facilitating, as will be seen below, the establishment of the device of the invention on the edge of the box.

    Par ailleurs, les surfaces d'appui 19, 21 sont de préférence sensiblement parallèles, au moins sur une partie de leur hauteur, à la partie évasée 8 de la boíte et disposées pour être en regard de cette partie évasée. Furthermore, the bearing surfaces 19, 21 are preferably substantially parallel, at least over part of their height, at the flared part 8 of the box and arranged to be in front of this flared part.

    Conformément à l'invention, les moyens de pression susmentionnés comprennent une bague de serrage 25. Cette bague 25 comporte une paroi supérieure 26 en forme de disque plat, pourvue d'une ouverture 27 dimensionnée pour laisser libre passage au goulot 13. Cette paroi supérieure 26, qui est destinée à venir prendre appui sur la plaque 10, est raccordée par sa périphérie à une paroi latérale annulaire 28 concentrique avec la jupe 11 autour de l'axe de symétrie A-A de la boíte.According to the invention, the aforementioned pressure means include a clamping ring 25. This ring 25 has an upper wall 26 in the form of flat disc, provided with an opening 27 sized to allow free passage to the neck 13. This upper wall 26, which is intended to come to bear on the plate 10, is connected by its periphery to an annular side wall 28 concentric with the skirt 11 around the axis of symmetry A-A of the box.

    Comme on le voit plus clairement sur les figures 5 à 8, cette paroi annulaire 28 de la bague de serrage comporte une première face intérieure 29 prenant naissance sur la face inférieure de la paroi supérieure 26 et s'étendant axialement jusqu'à parvenir à un niveau légèrement au-dessous de l'épaulement 22.As can be seen more clearly in FIGS. 5 to 8, this annular wall 28 of the clamping ring has a first inner face 29 originating on the underside of the upper wall 26 and extending axially until it reaches a level slightly below the shoulder 22.

    La paroi annulaire 28 comporte par ailleurs une deuxième face intérieure 30 décalée axialement et radialement par rapport à la première face intérieure 29, cette deuxième face 30 s'étendant axialement sensiblement jusqu'à hauteur de l'extrémité inférieure de la surface d'appui 21.The annular wall 28 also has a second inner face 30 offset axially and radially with respect to the first inner face 29, this second face 30 extending axially substantially up to the end lower of the support surface 21.

    La première face intérieure 29 est constituée par plusieurs (trois dans le mode de réalisation représenté sur les dessins) surfaces cylindriques 31, 32, 33 successives, de même longueur angulaire, chacune excentrée par rapport à l'axe de symétrie A-A. Ces surfaces cylindriques coopèrent respectivement avec trois surfaces cylindriques 34, 35, 36 correspondantes définissant une première face externe de la jupe 11.The first inner face 29 is formed by several (three in the mode of embodiment shown in the drawings) successive cylindrical surfaces 31, 32, 33, of same angular length, each eccentric with respect to the axis of symmetry A-A. These cylindrical surfaces cooperate respectively with three cylindrical surfaces 34, 35, 36 corresponding defining a first external face of the skirt 11.

    De la même manière, la deuxième face intérieure 30 est constituée par plusieurs (par exemple trois) surfaces cylindriques successives, de même longueur angulaire, chacune excentrée par rapport à l'axe de symétrie A-A, ces surfaces cylindriques coopérant respectivement avec trois surfaces correspondantes définissant une deuxième face externe de la jupe 11 ; on précisera que ces trois surfaces cylindriques ont respectivement le même centre que les surfaces 31, 32, 33.Likewise, the second inner face 30 is formed by several (for example three) successive cylindrical surfaces, of the same angular length, each eccentric with respect to the axis of symmetry A-A, these cylindrical surfaces cooperating respectively with three corresponding surfaces defining a second external face of the skirt 11; we will specify that these three cylindrical surfaces have respectively the same center as surfaces 31, 32, 33.

    Le dispositif ainsi décrit est complété par une languette souple 37 reliant la partie haute du bouchon 16 à la paroi supérieure 26 de la bague de serrage. Comme le montrent les figures 4 et 5, la languette 37 est fixée à la paroi 26 par un téton 38 solidaire de la languette, s'étendant axialement vers le bas et dont l'extrémité libre inférieure se termine par une partie élargie 39.The device thus described is completed by a flexible tongue 37 connecting the part top of the plug 16 to the upper wall 26 of the clamping ring. As the show Figures 4 and 5, the tongue 37 is fixed to the wall 26 by a stud 38 integral with the tongue, extending axially downwards and the free end of which lower ends with an enlarged part 39.

    Ce téton est introduit à force dans une encoche 40 ayant un rétrécissement à son entrée. This nipple is forced into a notch 40 having a narrowing at its Entrance.

    On précisera que lors de la rotation de la bague de serrage 25, cette partie élargie 39 peut circuler dans une zone élargie 41 de la gorge 24 comme le montre la figure 5.It will be noted that during the rotation of the clamping ring 25, this enlarged part 39 can circulate in an enlarged area 41 of the groove 24 as shown in FIG. 5.

    Le dispositif selon l'invention est enfin complété par une patte élastique 42 s'étendant axialement et solidarisée par son extrémité supérieure à la paroi latérale 28 de la bague de serrage, cette patte étant destinée à prendre appui élastiquement contre la paroi latérale 1 de la boíte.The device according to the invention is finally completed by an elastic tab 42 extending axially and secured by its upper end to the side wall 28 of the clamping ring, this tab being intended to bear elastically against the side wall 1 of the box.

    Le fonctionnement du dispositif qui vient d'être décrit est comme suit.The operation of the device which has just been described is as follows.

    Après déchirement de l'opercule 4 par soulèvement de la languette 5, l'utilisateur dégage une ouverture dans le couvercle 3 de la boíte, ouverture par laquelle il consomme une partie de la boisson contenue dans ladite boíte. Pour éviter tout renversement de la boisson restante et préserver la qualité et les propriétés de cette dernière, l'utilisateur applique ledit dispositif sur la boíte. A cet effet, il dispose ce dispositif sur la face supérieure (couvercle) 3 de cette boíte, engage l'excroissance 17 dans l'ouverture susmentionnée pratiquée dans le couvercle, puis applique au dispositif une légère force dirigée axialement de haut en bas pour amener, grâce à l'élasticité de la jupe 11, l'épaulement 22 à glisser axialement le long de la lèvre 7 jusqu'à ce qu'il vienne s'encastrer sous cette lèvre.After tearing of the cover 4 by lifting the tab 5, the user releases an opening in the cover 3 of the box, opening through which it consumes part of the drink contained in said box. To avoid everything spilling the remaining drink and preserving the quality and properties of this last, the user applies said device on the box. For this purpose, it has this device on the upper face (cover) 3 of this box, engages the protrusion 17 in the aforementioned opening in the cover, then apply to the device a slight force directed axially from top to bottom to bring, thanks to the elasticity of the skirt 11, the shoulder 22 to slide axially along the lip 7 until it come and fit under this lip.

    Bien entendu, selon le diamètre de la boíte utilisée, le rebord 6 de cette boíte va prendre place soit dans le logement supérieur 18 (boíte de faible diamètre), soit dans le logement inférieur 20 (boíte de grand diamètre).Of course, depending on the diameter of the box used, the rim 6 of this box will take place either in the upper housing 18 (small diameter box), or in the lower housing 20 (large diameter box).

    L'utilisateur communique alors à la bague de serrage 25 un mouvement de rotation, mouvement qui n'est pas transmis à la coiffe 9 puisque cette dernière est immobilisée en rotation par l'excroissance 17. Du fait du mouvement de rotation communiqué à la bague 25, par le jeu des surfaces cylindriques excentrées présentes sur les faces internes de la paroi latérale 28 de la bague et les faces externes de la jupe 11, on assiste alors à un serrage progressif qui se traduit par une pression de ladite paroi latérale 28 sur la jupe 11, ce qui a pour effet de presser la surface d'appui 19 contre la partie évasée de la boíte ; en raison du caractère élastique et compressible du matériau constituant la jupe, il en résulte l'étanchéité souhaitée entre l'intérieur de la boíte et l'atmosphère extérieure. The user then communicates to the clamping ring 25 a rotational movement, movement which is not transmitted to the cap 9 since the latter is immobilized in rotation by the protrusion 17. Due to the rotational movement communicated to the ring 25, by the play of the eccentric cylindrical surfaces present on the internal faces side wall 28 of the ring and the external faces of the skirt 11, we then assist a progressive tightening which results in a pressure of said side wall 28 on the skirt 11, which has the effect of pressing the bearing surface 19 against the flared part of the box ; due to the elastic and compressible nature of the material constituting the skirt, this results in the desired seal between the inside of the box and the atmosphere outside.

    On notera que chaque logement 18, 20 peut comprendre une surface d'appui 43, 44 positionnée pour être pressée, sous l'effet du serrage produit par la bague, contre la face interne du rebord 6, ce qui contribue, s'il en était besoin, à réaliser cette étanchéité.It will be noted that each housing 18, 20 may include a bearing surface 43, 44 positioned to be pressed, under the effect of the tightening produced by the ring, against the inner face of the rim 6, which contributes, if necessary, to achieve this seal.

    L'ensemble boíte-dispositif de fermeture résultant peut alors par exemple être stocké dans un réfrigérateur en attente d'un usage ultérieur. Il peut encore être accroché au moyen de la patte 42 par exemple à une ceinture ou un sac ou une lanière d'un équipement quelconque tel que celui d'un randonneur, d'un skieur, etc...The box-closing device assembly resulting can then for example be stored in a refrigerator awaiting further use. It can still be hung by means of the tab 42 for example to a belt or a bag or a thong of a any equipment such as that of a hiker, a skier, etc ...

    On ajoutera que la prise de boisson est facilitée grâce par la présence du goulot 13, cette opération étant de plus confortable en raison du bord arrondi du goulot.We will add that drinking is facilitated by the presence of the neck 13, this operation being more comfortable because of the rounded edge of the neck.

    Après usage complet de la boíte, le dispositif peut être aisément séparé de la boíte vide par rotation en sens inverse de la bague de serrage, puis traction axiale vers le haut.After complete use of the box, the device can be easily separated from the box vacuum by rotation in opposite direction of the clamping ring, then axial traction upwards.
