Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention concerne un bouchon à vis destiné à être monté par vissage pour fermer (ou obturer) le col d'un récipient et à rester attaché au récipient après ouverture du col.The present invention relates to a screw cap intended to be mounted by screwing to close (or seal) the neck of a container and to remain attached to the container after opening the neck.

ÉTAT DE LA TECHNIQUESTATE OF THE ART

Pour des raisons écologiques, dans la plupart des pays, de nouvelles règlementations imposent ou vont imposer que le bouchon d'un récipient, tel qu'une bouteille, reste attaché au récipient, même lorsque le bouchon laisse le col du récipient ouvert.For ecological reasons, in most countries, new regulations require or will require that the cap of a container, such as a bottle, remain attached to the container, even when the cap leaves the neck of the container open.

On connaît déjà un bouchon à friction destiné à être attaché à son récipient après ouverture du col du récipient. Ces bouchons à friction sont destinés à fermer un récipient en restant lié au col du récipient par l'effet des frottements (ou des frictions) ou par clipsage entre le bouchon et le col du récipient. Toutefois, ce bouchon à friction n'a pas les avantages d'un bouchon à vis qui permet de fermer le col d'un récipient de façon sécurisée.A friction stopper intended to be attached to its container after opening the neck of the container is already known. These friction plugs are intended to close a container while remaining linked to the neck of the container by the effect of friction (or friction) or by clipping between the stopper and the neck of the container. However, this friction cap does not have the advantages of a screw cap which allows the neck of a container to be closed securely.

En outre, la plupart des récipients sont fermés avec un bouchon à vis. Par conséquent, pour se conformer aux nouvelles règlementations, les lignes d'embouteillage qui sont configurées pour monter des bouchons à vis sur leurs récipients nécessitent une adaptation parfois complexe et coûteuse pour adapter la ligne d'embouteillage à ces bouchons à friction.In addition, most containers are closed with a screw cap. Therefore, to comply with new regulations, bottling lines that are configured to mount screw caps on their containers require sometimes complex and costly adaptation to adapt the bottling line to these friction caps.

Le document JP 2014 031202 décrit un bouchon à vis destiné à rester attaché à un récipient après ouverture du récipient.The document JP 2014 031202 describes a screw cap intended to remain attached to a container after opening the container.

EXPOSÉ DE L'INVENTIONDISCLOSURE OF THE INVENTION

La présente invention a pour objet de pallier ces inconvénients en proposant un bouchon à vis destiné à rester attacher au récipient qui ne demande pas d'adaptation des chaînes de montage.The object of the present invention is to overcome these drawbacks by providing a screw cap intended to remain attached to the container which does not require adaptation of the assembly lines.

À cet effet, l'invention concerne un bouchon à vis destiné à rester attaché à un récipient après ouverture du récipient.To this end, the invention relates to a screw cap intended to remain attached to a container after opening the container.

Le bouchon comprend :

  • une paroi cylindrique présentant un axe longitudinal, une première extrémité fermée par un fond et une deuxième extrémité ouverte, la paroi cylindrique présentant une surface interne comportant un filetage agencé pour coopérer avec un filetage agencé sur un col du récipient, la paroi cylindrique étant configurée pour se trouver alternativement dans une position fermée dans laquelle la paroi cylindrique est vissée sur le col et une position ouverte dans laquelle la paroi cylindrique est dévissée du col et le col est ouvert,
  • une bague de sécurité prolongeant la paroi cylindrique et destinée à être retenue au col par un élément de retenue agencé sur le récipient, la bague de sécurité étant reliée à la deuxième extrémité de la paroi cylindrique par au moins une connexion fracturable, la connexion fracturable étant agencée pour se fracturer lors d'un premier dévissage de la paroi cylindrique.
The cap includes:

DESCRIPTION DÉTAILLÉEDETAILED DESCRIPTION

La figure 1 représente une vue d'un premier mode de réalisation du bouchon 1 à vis destiné à rester attaché à un récipient 2, en particulier une bouteille, après ouverture du récipient 2. La figure 9 représente une vue d'un deuxième mode de réalisation du bouchon 1 à vis destiné à rester attaché à un récipient 2.The figure 1 shows a view of a first embodiment of the screw cap 1 intended to remain attached to a container 2, in particular a bottle, after opening of the container 2. The figure 9 shows a view of a second embodiment of the screw cap 1 intended to remain attached to a container 2.

De façon non limitative, le bouchon 1 est fabriqué en matériau plastique par une technologie de moulage par injection. Par exemple, le matériau plastique peut correspondre au polyéthylène haute densité (PEHD) ou au polypropylène (PP).In a nonlimiting manner, the cap 1 is made of plastic material by injection molding technology. For example, the plastic material can be high density polyethylene (HDPE) or polypropylene (PP).

Le bouchon 1 comprend une paroi cylindrique 3 présentant un axe longitudinal 4.The stopper 1 comprises a cylindrical wall 3 having a longitudinal axis 4.

La paroi cylindrique 3 présente une forme de cylindre de révolution. L'axe longitudinal 4 est confondu avec l'axe de cylindre. La paroi cylindrique 3 comporte une extrémité 5 fermée par un fond 6 et une extrémité 7 ouverte. La paroi cylindrique 3 présente une surface interne 8 comportant un filetage 9 agencé pour coopérer avec un filetage 10 agencé sur un col 11 du récipient 2 (figures 4, 7, 11 et 12). La paroi cylindrique 3 est configurée pour se trouver alternativement dans une position fermée (figures 7 et 11) dans laquelle la paroi cylindrique 3 est vissée sur le col 11 et une position ouverte (figures 8 et 12) dans laquelle la paroi cylindrique 3 est dévissée du col 11 et le col 11 est ouvert.The cylindrical wall 3 has the shape of a cylinder of revolution. The longitudinal axis 4 coincides with the cylinder axis. The cylindrical wall 3 has one end 5 closed by a bottom 6 and one end 7 open. The cylindrical wall 3 has an internal surface 8 comprising a thread 9 arranged to cooperate with a thread 10 arranged on a neck 11 of the container 2 ( figures 4 , 7 , 11 and 12 ). The cylindrical wall 3 is configured to lie alternately in a closed position ( figures 7 and 11 ) in which the cylindrical wall 3 is screwed onto the neck 11 and an open position ( figures 8 and 12 ) in which the cylindrical wall 3 is unscrewed from the neck 11 and the neck 11 is open.

Le bouchon 1 comprend en outre une bague de sécurité 12 prolongeant la paroi cylindrique 3. La bague de sécurité 12 est destinée à être retenue au col 11 par un élément de retenue 13 agencé sur le récipient 2 (figures 4 et 11). L'élément de retenue 13 peut être une saillie circulaire ou au moins une portion de saillie circulaire agencée sur le col 11 du récipient 2.The stopper 1 further comprises a safety ring 12 extending the cylindrical wall 3. The safety ring 12 is intended to be retained on the neck 11 by a retaining element 13 arranged on the container 2 ( figures 4 and 11 ). The retaining element 13 may be a circular projection or at least a portion of a circular projection arranged on the neck 11 of the container 2.

La bague de sécurité 12 est reliée à l'extrémité 7 de la paroi cylindrique 3 par au moins une connexion fracturable 14. La connexion fracturable 14 est agencée pour se fracturer lors d'un premier dévissage de la paroi cylindrique 3.The safety ring 12 is connected to the end 7 of the cylindrical wall 3 by at least one fracturable connection 14. The fracturable connection 14 is arranged to fracture during a first unscrewing of the cylindrical wall 3.

Une portion de la paroi cylindrique 3 forme une languette 15 qui s'étend entre un bout 16 et un bout 17 parallèlement à l'axe longitudinal 4. Le bout 16 est relié à la paroi cylindrique 3 par une charnière 18. La charnière 18 peut correspondre à un amincissement de l'épaisseur de la paroi cylindrique 3 qui relie la languette 15. Cet amincissement d'épaisseur permet à la languette 15 de pouvoir être articulée à la paroi cylindrique 3 au niveau de l'amincissement.A portion of the cylindrical wall 3 forms a tongue 15 which extends between an end 16 and an end 17 parallel to the longitudinal axis 4. The end 16 is connected to the cylindrical wall 3 by a hinge 18. The hinge 18 can correspond to a thinning of the thickness of the cylindrical wall 3 which connects the tongue 15. This thinning of thickness allows the tongue 15 to be able to be articulated to the cylindrical wall 3 at the level of the thinning.

Le bout 17 est relié à la bague de sécurité 12 par l'intermédiaire d'un élément de liaison 19. L'élément de liaison 19 est agencé pour permettre le déplacement (en translation) de la paroi cylindrique 3 le long de l'axe longitudinal 4 lors d'un dévissage de la paroi cylindrique 3.The end 17 is connected to the safety ring 12 by means of a connecting element 19. The connecting element 19 is arranged to allow the displacement (in translation) of the cylindrical wall 3 along the axis. longitudinal 4 when unscrewing the cylindrical wall 3.

La languette 15 présente des bords longitudinaux 20 parallèles à l'axe longitudinal 4. Chacun des bords longitudinaux 20 peuvent être relié respectivement à la paroi cylindrique 3 par une ligne déchirable 21. Chaque ligne déchirable 21 est agencée pour se déchirer après le premier dévissage de la paroi cylindrique 3 et une première ouverture du col 11 du récipient 2. Ainsi, chaque ligne déchirable 21 peut correspondre à une ligne de prédécoupe qui se déchire lorsque la paroi cylindrique 3 est dégagée du col 11 du récipient 2 puis basculée par rapport à la languette 15, après le premier dévissage de la paroi cylindrique 3.The tongue 15 has longitudinal edges 20 parallel to the longitudinal axis 4. Each of the longitudinal edges 20 can be connected respectively to the cylindrical wall 3 by a tear line 21. Each tear line 21 is arranged to tear after the first unscrewing of the cylindrical wall 3 and a first opening of the neck 11 of the container 2. Thus, each tear-off line 21 may correspond to a precut line which tears when the cylindrical wall 3 is released from the neck 11 of the container 2 and then tilted with respect to the tab 15, after the first unscrewing of the cylindrical wall 3.

Par ailleurs, l'élément de liaison 19 peut comprend deux bras 22. Chacun des bras présente une extrémité 23 et une extrémité 24. Les bras 22 sont joints l'un à l'autre par l'extrémité 23 et s'écartent symétriquement de part et d'autre de la languette 15 vers l'extrémité 24. L'extrémité 24 est reliée à la bague de sécurité 12.Furthermore, the connecting element 19 can comprise two arms 22. Each of the arms has an end 23 and an end 24. The arms 22 are joined to each other by the end 23 and are symmetrically separated from each other. either side of the tab 15 towards the end 24. The end 24 is connected to the safety ring 12.

Chacun des bras sont dimensionnés pour fournir une souplesse permettant à la paroi cylindrique 3 de se déplacer en translation le long de l'axe longitudinal 4 lors du dévissage de la paroi cylindrique 3 jusqu'à ce que la paroi cylindrique soit complétement dévissé. La languette 15 et l'élément de liaison 19 retienne alors la paroi cylindrique 3 à la bague de sécurité 12 qui est retenue au col 11 du récipient 2. Par ailleurs, les bras sont dimensionnés pour résister à une force de traction maximale suffisante pour empêcher l'arrachement de la paroi cylindrique 3 du récipient. La force de traction peut être définie en fonction d'une utilisation normale du bouchon. La force de traction maximale peut être définie en fonction de normes fixées pour l'ouverture d'un bouchon 1. De façon non limitative, les bras 22 sont dimensionnés pour que la force de traction maximale soit sensiblement égale à 35 N.Each of the arms are dimensioned to provide flexibility allowing the cylindrical wall 3 to move in translation along the longitudinal axis 4 when unscrewing the cylindrical wall 3 until the cylindrical wall is completely unscrewed. The tongue 15 and the connecting element 19 then retain the cylindrical wall 3 to the safety ring 12 which is retained at the neck 11 of the container 2. Furthermore, the arms are dimensioned to withstand a maximum tensile force sufficient to prevent the tearing of the cylindrical wall 3 of the container. The tensile force can be set based on normal use of the plug. The maximum tensile force can be defined as a function of standards set for opening a cap 1. In a non-limiting manner, the arms 22 are dimensioned so that the maximum tensile force is substantially equal to 35 N.

Selon le premier mode de réalisation, l'élément de liaison 19 comprend en outre une deuxième charnière 25 reliant le bout 17 de la languette 15 aux bras 22 (au niveau de l'extrémité 23 de chacun des bras).According to the first embodiment, the connecting element 19 further comprises a second hinge 25 connecting the end 17 of the tongue 15 to the arms 22 (at the level of the end 23 of each of the arms).

La deuxième extrémité 7 de la paroi cylindrique 3 peut comprendre une portion de bord présentant une échancrure 26. Les bras 22 sont logés dans l'échancrure 26. Les bras 22 complètent le bord de l'extrémité 7 de la paroi cylindrique 3 au niveau de l'échancrure 26. Les bras 22 remplissent ainsi l'espace laissé par l'échancrure 26.The second end 7 of the cylindrical wall 3 may include an edge portion having a notch 26. The arms 22 are housed in the notch 26. The arms 22 complete the edge of the end 7 of the cylindrical wall 3 at the level of the notch 26. The arms 22 thus fill the space left by the notch 26.

L'échancrure 26 peut présenter une forme permettant de faciliter le vissage de la paroi cylindrique 3 en évitant une collision entre le filetage 9 et le col 11 du récipient 2. Par exemple, l'espacement entre le bord de l'échancrure 26 et les bras 22 s'élargie progressivement en partant de l'extrémité 24 vers l'extrémité 23.The notch 26 may have a shape making it possible to facilitate the screwing of the cylindrical wall 3 while avoiding a collision between the thread 9 and the neck 11 of the container 2. For example, the spacing between the edge of the notch 26 and the arm 22 widens progressively from end 24 to end 23.

Par ailleurs, la connexion fracturable 14 peut relier la bague de sécurité 12 à l'extrémité 7 de la paroi cylindrique 3. La connexion fracturable 14 relie également la bague de sécurité 12 aux bras 22. L'extrémité 7 de chacun des bras 22 peut présenter une portion 27 s'écartant de l'échancrure 26 pour relier la bague de sécurité 12.Furthermore, the fracturable connection 14 can connect the safety ring 12 to the end 7 of the cylindrical wall 3. The fracturable connection 14 also connects the safety ring 12 to the arms 22. The end 7 of each of the arms 22 can present a portion 27 moving away from the notch 26 to connect the safety ring 12.

Avantageusement, chaque ligne déchirable 21 relie également chacun des bras 22 à la paroi cylindrique 3. Ainsi, la ligne déchirable 21 qui relie chacun des bords longitudinaux 20 à la paroi cylindrique 3 s'étend pour relier chacun des bras 22 à la paroi cylindrique 3. La ligne déchirable 21 entre chacun des bras 22 et la paroi cylindrique 3 permet d'améliorer l'étanchéité du bouchon 1 lorsque la paroi cylindrique 3 est dans la position fermée avant le premier dévissage de la paroi cylindrique 3.Advantageously, each tear-off line 21 also connects each of the arms 22 to the cylindrical wall 3. Thus, the tear-off line 21 which connects each of the longitudinal edges 20 to the cylindrical wall 3 extends to connect each of the arms 22 to the cylindrical wall 3. The tear line 21 between each of the arms 22 and the cylindrical wall 3 makes it possible to improve the tightness of the stopper 1 when the cylindrical wall 3 is in the closed position before the first unscrewing of the cylindrical wall 3.

La bague de sécurité 12 peut comprendre au moins un élément d'appui 28. Ce ou ces éléments d'appui 28 sont agencés pour que la bague de sécurité 12 en regard des bras 22 puisse s'appuyer contre les bras 22 lors d'un passage en force de la bague de sécurité 12 sur l'élément de retenue 13 pour monter le bouchon 1 sur le récipient 2 sur une ligne d'embouteillage. Les figures 3 et 6 montrent quatre éléments d'appui 28 repartis sur la bague de sécurité 12 en regard des bras 22. Le ou les éléments d'appui 28 peuvent correspondre à un ou des saillies de forme sensiblement parallélépipédique monobloc avec la bague de sécurité 12.The safety ring 12 may comprise at least one support element 28. This or these support elements 28 are arranged so that the safety ring 12 facing the arms 22 can rest against the arms 22 during a force passage of the safety ring 12 on the retaining element 13 to mount the cap 1 on the container 2 on a bottling line. The figures 3 and 6 show four support elements 28 distributed over the safety ring 12 opposite the arms 22. The support element or elements 28 may correspond to a or projections of substantially parallelepipedal shape in one piece with the safety ring 12.

Selon le premier mode de réalisation, le bouchon 1 peut également comprendre une languette 29 prolongeant la languette 15 et agencée sensiblement dans un même plan que la languette 15. La languette 29 est séparée de la languette 15 par l'élément de liaison 19. La bague de sécurité 12 présente une découpe 30 adaptée pour loger la languette 29. La languette 29 est adaptée pour empêcher la rotation du bouchon 1 autour de l'axe longitudinal 4 lorsque la paroi cylindrique 3 se trouve dans la position ouverte. La rotation du bouchon 1 autour de l'axe longitudinal 4 est empêchée par les forces de frottement causées par l'appui, sur le récipient 2, de la languette 29. L'appui de la languette 29 sur le récipient 2 est une conséquence du basculement du plan comportant la languette 15 et la languette 29 autour de l'élément de liaison 19 quand la paroi cylindrique 3 est amenée dans la position ouverte.According to the first embodiment, the stopper 1 can also include a tongue 29 extending the tongue 15 and arranged substantially in the same plane as the tongue 15. The tongue 29 is separated from the tongue 15 by the connecting element 19. The safety ring 12 has a cutout 30 adapted to accommodate the tongue 29. The tongue 29 is adapted to prevent rotation of the stopper 1 around the longitudinal axis 4 when the cylindrical wall 3 is in the open position. The rotation of the stopper 1 around the longitudinal axis 4 is prevented by the frictional forces caused by the pressing, on the container 2, of the tab 29. The pressing of the tab 29 on the container 2 is a consequence of tilting of the plane comprising the tongue 15 and the tongue 29 around the connecting element 19 when the cylindrical wall 3 is brought into the open position.

Selon le deuxième mode de réalisation, le bouchon 1 comprend également une languette 29 prolongeant la languette 15 et agencée sensiblement dans un même plan commun que la languette 15 (figures 9 et 10). La bague de sécurité 12 présente aussi une découpe 30 adaptée pour loger la languette 29. La languette 29 comprend au moins une butée 34 faisant saillie sur la languette 29 vers l'extérieur de la paroi cylindrique 3.According to the second embodiment, the stopper 1 also comprises a tongue 29 extending the tongue 15 and arranged substantially in the same common plane as the tongue 15 ( figures 9 and 10 ). The safety ring 12 also has a cutout 30 adapted to accommodate the tongue 29. The tongue 29 comprises at least one stop 34 projecting from the tongue 29 towards the outside of the cylindrical wall 3.

La ou les butées 34 sont agencées pour s'appuyer contre un épaulement 35 agencé sur le récipient 2 après un basculement du plan commun quand la paroi cylindrique 3 est amenée dans une configuration de blocage du bouchon 1 (figure 12). La configuration de blocage représentée dans la figure 12 correspond à une configuration de la position ouverte de la paroi cylindrique 3 dans laquelle la paroi circulaire 3 est empêchée de revenir dans la position fermée.The stop or stops 34 are arranged to rest against a shoulder 35 arranged on the container 2 after a tilting of the common plane when the cylindrical wall 3 is brought into a locking configuration of the stopper 1 ( figure 12 ). The blocking configuration shown in figure 12 corresponds to a configuration of the open position of the cylindrical wall 3 in which the circular wall 3 is prevented from returning to the closed position.

Les deux bras 22 de l'élément de liaison 19 étant configurés pour amener le plan commun vers la bague de sécurité 12 après le basculement jusqu'à ce que la ou les butées 34 s'appuient contre l'épaulement 35.The two arms 22 of the connecting element 19 being configured to bring the common plane towards the safety ring 12 after tilting until the stop or stops 34 bear against the shoulder 35.

L'épaulement 35 peut correspondre au moins en partie à l'élément de retenue 13 qui retient la bague de sécurité 12 au col 11 du récipient 2.The shoulder 35 may correspond at least in part to the retaining element 13 which retains the safety ring 12 to the neck 11 of the container 2.

Avantageusement, la ou les butées 34 présentent une forme allongée ou de godron en saillie sur la languette 29. La forme allongée possède, dans un sens allant vers l'extrémité libre de la languette 29, une partie 341 et une partie 342 (figures 11 et 12). La partie 341 est configurée pour être en butée contre épaulement 35 lorsque la paroi cylindrique 3 se trouve dans la configuration de blocage. La partie 342 présentant une forme facilitant un passage vers la configuration de blocage lorsque la paroi cylindrique 3 est dans la position ouverte.Advantageously, the stop or stops 34 have an elongated or gadroon shape projecting from the tongue 29. The elongated shape has, in a direction going towards the free end of the tongue 29, a part 341 and a part 342 ( figures 11 and 12 ). Part 341 is configured to abut against shoulder 35 when cylindrical wall 3 is in the locking configuration. The part 342 having a shape facilitating a passage to the blocking configuration when the cylindrical wall 3 is in the open position.

Ainsi, cette ou ces butées 34 forment un point dur autour duquel le basculement est réalisé pour passer vers la configuration de blocage.Thus, this or these abutments 34 form a hard point around which the tilting is carried out to pass towards the locking configuration.

De façon non limitative, la partie 341 présente une forme droite sensiblement perpendiculaire à la languette 29. La forme droite possède une première extrémité située sur la surface supérieure de la languette 29 qui est dirigée vers l'extérieur de la paroi cylindrique 3 et une deuxième extrémité libre. La partie 342 présente une forme arrondie. La forme arrondie rejoignant la surface supérieure de la languette 29 et la deuxième extrémité libre de la partie 341.In a nonlimiting manner, the part 341 has a straight shape substantially perpendicular to the tongue 29. The straight shape has a first end located on the upper surface of the tongue 29 which is directed towards the outside of the cylindrical wall 3 and a second free end. Part 342 has a rounded shape. The rounded shape joining the upper surface of the tongue 29 and the second free end of the part 341.

Ainsi, lorsque la paroi cylindrique est dans la position ouverte, le passage vers la configuration de blocage se fait par le glissement de l'épaulement 35 contre la partie 342. La forme arrondie de la partie 342 facilite le glissement. Ce glissement entraîne une sollicitation de la charnière 18 par le rapprochement de l'extrémité libre de la languette 29 vers l'intérieur du bouchon 1. Dès que l'épaulement 35 atteint la deuxième extrémité libre de la partie 341, l'extrémité libre de la languette 29 s'éloigne de l'intérieur du bouchon 1 grâce à l'élasticité de la charnière 18. Les deux bras 22 permettent alors l'appui de la partie 341 contre l'épaulement 35.Thus, when the cylindrical wall is in the open position, the passage to the blocking configuration is effected by sliding the shoulder 35 against the part 342. The rounded shape of the part 342 facilitates the sliding. This sliding causes a biasing of the hinge 18 by the approach of the free end of the tongue 29 towards the inside of the stopper 1. As soon as the shoulder 35 reaches the second free end of the part 341, the free end of the tab 29 moves away from the inside of the stopper 1 thanks to the elasticity of the hinge 18. The two arms 22 then allow the support of the part 341 against the shoulder 35.

Avantageusement, la forme allongée de la ou des butées 34 présente un axe longitudinal faisant un angle non nul avec l'axe longitudinal 4. La figure 9 montre deux butées 34 dont les formes allongées s'écartent symétriquement au fur et à mesure que l'on s'approche de la charnière 18 selon un angle non nul par rapport à l'axe longitudinal 4.Advantageously, the elongated shape of the stop or stops 34 has a longitudinal axis forming a non-zero angle with the longitudinal axis 4. The figure 9 shows two stops 34 whose elongated shapes move apart symmetrically as one approaches the hinge 18 at a non-zero angle with respect to the longitudinal axis 4.

Le bouchon 1 peut comprendre en outre une jupe cylindrique 31 de bouchage interne portée par le fond 6 et configurée pour pénétrer dans le col 11 du récipient 2 lors du vissage de la paroi cylindrique 3 vers la position fermée.The stopper 1 can further comprise a cylindrical internal sealing skirt 31 carried by the bottom 6 and configured to penetrate into the neck 11 of the container 2 when screwing the cylindrical wall 3 towards the closed position.

De préférence, la jupe cylindrique 31 présente un axe longitudinal ou axe de cylindre confondu avec l'axe longitudinal 4 de la paroi cylindrique 3.Preferably, the cylindrical skirt 31 has a longitudinal axis or cylinder axis coinciding with the longitudinal axis 4 of the cylindrical wall 3.

Entre la jupe cylindrique 31 et la paroi cylindrique 3, le fond 6 du bouchon 1 est agencé pour que l'extrémité libre du col 11 entre en butée contre le fond 6 du bouchon 1 lorsque la paroi cylindrique est dans la position fermée.Between the cylindrical skirt 31 and the cylindrical wall 3, the bottom 6 of the stopper 1 is arranged so that the free end of the neck 11 abuts against the bottom 6 of the stopper 1 when the cylindrical wall is in the closed position.

Par exemple, la partie du fond 6 qui se trouve en correspondance avec la jupe cylindrique 31 est extérieurement rehaussée pour augmenter la surface extérieure du bouchon 1. La cavité délimitée par la jupe cylindrique 31 et la cavité engendrée par le rehaussement extérieur du fond 6 s'additionnant pour former une grande cavité unique à paroi lisse. Un retrait circulaire est formé entre la partie rehaussée et la partie non rehaussée du fond 6. L'extrémité libre du col 11 du récipient entre en butée contre la partie non rehaussée du fond 6, lorsque la paroi cylindrique est dans la position fermée. Cela permet d'assurer une étanchéité du bouchon 1.For example, the part of the bottom 6 which is located in correspondence with the cylindrical skirt 31 is externally raised to increase the external surface of the stopper 1. The cavity delimited by the cylindrical skirt 31 and the cavity generated by the external raising of the base 6 s 'adding to form a single large, smooth-walled cavity. A circular recess is formed between the raised part and the non-raised part of the bottom 6. The free end of the neck 11 of the container abuts against the non-raised part of the bottom 6, when the cylindrical wall is in the closed position. This ensures that the cap 1 is leaktight.

Le bout 16 reliant la languette 15 à la paroi cylindrique 3 peut être à une hauteur inférieure ou égale à une hauteur située au niveau du fond 6 du bouchon 1 contre laquelle l'extrémité libre du col 11 du récipient 2 entre en butée, lorsque la paroi cylindrique 3 est dans la position fermée.The end 16 connecting the tab 15 to the cylindrical wall 3 may be at a height less than or equal to a height located at the level of the bottom 6 of the stopper 1 against which the free end of the neck 11 of the container 2 comes into abutment, when the cylindrical wall 3 is in the closed position.

Avantageusement, la jupe cylindrique 31 comprend un bord libre présentant une échancrure 32 en regard de la languette 15. Cette échancrure 32 permet de faciliter le dégagement de la paroi cylindrique 3 du col 11 du récipient 2 après son dévissage. Il permet également de faciliter la mise en place de la paroi cylindrique 3 sur le col 11 du récipient 2 avant le vissage de la paroi cylindrique 3 sur le col 11.Advantageously, the cylindrical skirt 31 comprises a free edge having a notch 32 facing the tongue 15. This notch 32 makes it possible to facilitate the release of the cylindrical wall 3 from the neck 11 of the container 2 after its unscrewing. It also makes it possible to facilitate the positioning of the cylindrical wall 3 on the neck 11 of the container 2 before the cylindrical wall 3 is screwed on the neck 11.

La paroi cylindrique 3 peut présenter une surface externe comportant des reliefs de préhension 33. De façon non limitative, les reliefs de préhension correspondent à des ailettes diamétrales régulièrement réparties sur la surface externe de la paroi cylindrique 3.The cylindrical wall 3 may have an external surface comprising gripping reliefs 33. In a non-limiting manner, the gripping reliefs correspond to diametral fins regularly distributed over the external surface of the cylindrical wall 3.

Selon un mode de réalisation, la bague de sécurité 12 comprend une partie circulaire externe et une partie circulaire interne. La partie circulaire externe vient en prolongeant la paroi cylindrique 3. La partie circulaire interne est retournée par rapport à la partie circulaire externe à l'intérieur de la bague de sécurité 12. La bague de sécurité 12 est ainsi destinée à être retenue au col 11 par la coopération de la partie circulaire interne avec l'élément de retenue 13.According to one embodiment, the safety ring 12 comprises an outer circular part and an inner circular part. The outer circular part comes by extending the cylindrical wall 3. The inner circular part is turned over with respect to the outer circular part inside the safety ring 12. The safety ring 12 is thus intended to be retained at the neck 11. by the cooperation of the internal circular part with the retaining element 13.

Le bouchon peut être utilisé pour n'importe quel récipient 2 présentant un col 11 à vis. Le bouchon 1 peut également présenter un diamètre adapté pour n'importe quel col 11 de récipient à vis. Le diamètre du bouchon 1 peut donc être égal à n'importe quel diamètre pour pouvoir être utilisé sur n'importe quel diamètre de col 11 à vis d'un récipient 2.The cap can be used for any container 2 having a screw neck 11. The stopper 1 can also have a diameter suitable for any neck 11 of a screw container. The diameter of the stopper 1 can therefore be equal to any diameter in order to be able to be used on any diameter of the neck 11 screwed onto a container 2.

Par ailleurs, le bouchon 1 peut être utilisé pour un récipient 2 pouvant contenir tout type de liquide ou boisson. De façon non limitative, le récipient 2 peut être un récipient 2 pouvant contenir un liquide plat, un liquide gazeux, un jus de fruit, du lait, etc. Les différentes parties du bouchon 1, telles que la paroi cylindrique 3, le fond 6, la jupe cylindrique 31, le filetage 9 peuvent être dimensionnées en fonction du liquide ou de la boisson destinée à être contenu dans le récipient 2. Par exemple, ces différentes parties peuvent être plus ou moins épaisses. De même, le filetage 9 peut présenter des filets plus ou moins serrés et/ou plus ou moins épais. De même, les filets du filetage 9 peuvent présenter des interruptions selon le liquide ou la boisson destiné à être contenu dans le récipient 2.Furthermore, the stopper 1 can be used for a container 2 which can contain any type of liquid or drink. In a nonlimiting manner, the container 2 can be a container 2 which can contain a flat liquid, a gaseous liquid, a fruit juice, milk, etc. The different parts of the stopper 1, such as the cylindrical wall 3, the bottom 6, the cylindrical skirt 31, the thread 9 can be sized according to the liquid or the drink intended to be contained in the container 2. For example, these different parts can be more or less thick. Likewise, the thread 9 may have more or less tight and / or more or less thick threads. Likewise, the threads of the thread 9 may have interruptions depending on the liquid or the drink intended to be contained in the container 2.
