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 destiné à contenir en particulier un liquide effervescent. Le bouchon est destiné 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 intended to contain in particular an effervescent liquid. The stopper is intended to remain attached to the container after the neck has been opened.

ÉTAT DE LA TECHNIQUESTATE OF THE ART

Pour des raisons écologiques, dans la plupart des pays, de nouvelles réglementations 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 impose or will impose that the stopper of a container, such as a bottle, remains attached to the container, even when the stopper 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 cap intended to be attached to its container after opening the neck of the container is already known. These friction caps 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 cap and the neck of the container. However, this friction cap does not have the advantages of a screw cap which makes it possible to close the neck of a container securely.

En outre, la plupart des récipients sont fermés avec un bouchon à vis. Par conséquent, pour se conformer aux nouvelles réglementations, 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.Also, 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 US 2011/0114593 présente un exemple de bouchon à vis attaché à un récipient, selon l'art antérieur, présentant les caractéristiques techniques mentionnées dans le préambule de la présente revendication 1.The document US 2011/0114593 presents an example of a screw cap attached to a container, according to the prior art, having the technical characteristics mentioned in the preamble of the present claim 1.

Par ailleurs, les bouchons à vis peuvent comporter des caractéristiques différentes, tel qu'un angle de dévissage, selon le liquide contenu dans le récipient que ferme le bouchon. L'angle de dévissage correspond à un angle de rotation nécessaire pour un bouchon pour aller d'une position complètement vissée à une position complètement dévissée. En effet, afin de résister à la pression du gaz produit par le liquide effervescent dans le récipient, le bouchon d'un récipient contenant un liquide effervescent nécessite un angle de dévissage plus important qu'un angle de dévissage pour un bouchon d'un récipient contenant un liquide plat. Par exemple, le bouchon d'un récipient contenant un liquide effervescent peut présenter un angle de dévissage de l'ordre de 650° à 700° alors que le bouchon d'un récipient contenant un liquide plat peut présenter un angle de dévissage de l'ordre de 360° seulement. Or, plus l'angle de dévissage est important, plus la distance de déplacement du bouchon pour un dévissage avant l'ouverture du récipient est importante. Cette distance de déplacement peut être un inconvénient lorsque le bouchon est attaché au récipient.Furthermore, screw caps may have different characteristics, such as an unscrewing angle, depending on the liquid contained in the container that the cap closes. The unscrewing angle corresponds to an angle of rotation necessary for a cap to go from a completely screwed position to a completely unscrewed position. Indeed, in order to resist the pressure of the gas produced by the effervescent liquid in the container, the cap of a container containing an effervescent liquid requires a greater unscrewing angle than an unscrewing angle for a cap of a container. containing a flat liquid. For example, the cap of a container containing an effervescent liquid can have an unscrewing angle of the order of 650° to 700° while the cap of a container containing a flat liquid can have an unscrewing angle of 360° order only. However, the greater the unscrewing angle, the greater the distance of movement of the stopper for unscrewing before opening the container. This travel distance can be a disadvantage when the cap is attached to the container.

EXPOSÉ DE L'INVENTIONDISCLOSURE OF THE INVENTION

La présente invention a pour objet de pallier cet inconvénient en proposant un bouchon à vis destiné à rester attacher au récipient qui peut être utilisé pour un récipient destiné à contenir un liquide effervescent.The object of the present invention is to overcome this drawback by proposing a screw cap intended to remain attached to the container which can be used for a container intended to contain an effervescent liquid.

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 the container has been opened.

Selon l'invention, le bouchon comprend :

  • une paroi cylindrique présentant un premier 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, la paroi cylindrique comprenant une portion formant une languette s'étendant entre un bout d'attache et un bout libre parallèlement au premier axe longitudinal, le bout d'attache étant relié à la paroi cylindrique par une charnière, la languette présentant des bords longitudinaux parallèles au premier axe longitudinal, la languette présentant en outre au moins une fente possédant un deuxième axe longitudinal sensiblement parallèle au premier axe longitudinal, la ou les fentes présentant une largeur orthogonale au deuxième axe longitudinal ;
  • 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 ;
  • deux bras présentant chacun une première extrémité et une deuxième extrémité, la première extrémité de chacun des bras étant jointe à un bord longitudinal de la languette, les bras s'éloignant l'un de l'autre symétriquement de part et d'autre de la languette vers la deuxième extrémité reliée à la bague de sécurité, les bras étant agencés pour tirer de part et d'autre de la languette en permettant un agrandissement de la largeur de la ou des fentes lors d'un déplacement de la paroi cylindrique selon le premier axe longitudinal pendant un dévissage de la paroi cylindrique.
According to the invention, the stopper comprises:
  • a cylindrical wall having a first longitudinal axis, a first end closed by a bottom and a second open end, the cylindrical wall having an internal surface comprising a thread arranged to cooperate with a thread arranged on a neck of the container, the cylindrical wall being configured to alternately be in a closed position in which the cylindrical wall is screwed onto the neck and an open position in which the cylindrical wall is unscrewed from the neck and the neck is opened, the cylindrical wall comprising a portion forming a tongue extending between an attachment end and an end free parallel to the first longitudinal axis, the attachment end being connected to the cylindrical wall by a hinge, the tongue having longitudinal edges parallel to the first longitudinal axis, the tongue further having at least one slot having a second longitudinal axis substantially parallel at the first longitudinal axis, the slot(s) having a width orthogonal to the second longitudinal axis;
  • a safety ring extending the cylindrical wall and intended to be retained at the neck by a retaining element arranged on the container, the safety ring being connected to the second end of the cylindrical wall by at least one breakable connection, the breakable connection being arranged to fracture during a first unscrewing of the cylindrical wall;
  • two arms each having a first end and a second end, the first end of each of the arms being joined to a longitudinal edge of the tongue, the arms moving away from each other symmetrically on either side of the tongue towards the second end connected to the safety ring, the arms being arranged to pull on either side of the tongue, allowing the width of the slot or slots to be enlarged when the cylindrical wall moves along the first longitudinal axis during unscrewing of the cylindrical wall.

Ainsi, grâce à la fente ou aux fentes, la distance de déplacement du bouchon pour un dévissage avant l'ouverture du récipient est augmentée. L'action conjuguée de l'élasticité des bras et de l'agrandissement de la largeur de la ou des fentes permet d'obtenir une amplitude de déplacement de la paroi cylindrique plus importante qu'une amplitude de déplacement assurée seulement par l'action de l'élasticité des bras.Thus, thanks to the slot or slots, the displacement distance of the cap for unscrewing before opening the container is increased. The combined action of the elasticity of the arms and the enlargement of the width of the slot(s) makes it possible to obtain a greater amplitude of displacement of the cylindrical wall than a amplitude of displacement ensured only by the action of the elasticity of the arms.

En outre, la languette présente deux fentes dont les deuxièmes axes longitudinaux sont parallèles entre eux.In addition, the tab has two slots whose second longitudinal axes are parallel to each other.

De plus, une fente des deux fentes est symétrique à l'autre fente des deux fentes selon une symétrie axiale, la symétrie axiale étant définie par un axe central de la languette parallèle au premier axe longitudinal.In addition, one slot of the two slots is symmetrical to the other slot of the two slots according to an axial symmetry, the axial symmetry being defined by a central axis of the tongue parallel to the first longitudinal axis.

Par ailleurs, la languette comprend une butée faisant saillie sur la languette vers l'extérieur de la paroi cylindrique au bout libre de la languette, la butée étant agencée pour s'appuyer contre un épaulement agencé sur le récipient après un basculement de la languette quand la paroi cylindrique est amenée dans une configuration de blocage du bouchon, les deux bras étant configurés pour amener la languette vers la bague de sécurité après le basculement jusqu'à ce que la butée s'appuie contre l'épaulement, la configuration de blocage correspondant à une configuration de la position ouverte de la paroi cylindrique dans laquelle la paroi circulaire est empêchée de revenir dans la position fermée.Furthermore, the tongue comprises an abutment projecting from the tongue towards the outside of the cylindrical wall at the free end of the tongue, the abutment being arranged to bear against a shoulder arranged on the container after a tilting of the tongue when the cylindrical wall is brought into a blocking configuration of the stopper, the two arms being configured to bring the tongue towards the safety ring after tilting until the abutment rests against the shoulder, the corresponding blocking configuration to a configuration of the open position of the cylindrical wall in which the circular wall is prevented from returning to the closed position.

En outre, la bague de sécurité présente une découpe adaptée pour loger le bout libre de la languette.In addition, the safety ring has a cutout adapted to accommodate the free end of the tab.

De plus, chacun des bords longitudinaux est relié respectivement à la paroi cylindrique par une ligne déchirable, chaque ligne déchirable étant agencée pour se déchirer après le premier dévissage de la paroi cylindrique et une première ouverture du col du récipient.In addition, each of the longitudinal edges is respectively connected to the cylindrical wall by a tearable line, each tearable line being arranged to tear after the first unscrewing of the cylindrical wall and a first opening of the neck of the container.

Avantageusement, la deuxième extrémité de la paroi cylindrique comprend une portion de bord présentant une échancrure, les bras étant logés au moins en partie dans l'échancrure en complétant le bord de la deuxième extrémité de la paroi cylindrique au niveau de l'échancrure, en ce que la connexion fracturable relie la bague de sécurité, d'une part, à la deuxième extrémité de la paroi cylindrique et, d'autre part, aux bras.Advantageously, the second end of the cylindrical wall comprises an edge portion having an indentation, the arms being housed at least partly in the indentation by completing the edge of the second end of the cylindrical wall at the level of the indentation, in that the frangible connection connects the safety ring, on the one hand, to the second end of the cylindrical wall and, on the other hand, to the arms.

De plus, chaque ligne déchirable relie également chacun des bras à la paroi cylindrique.In addition, each tear line also connects each of the arms to the cylindrical wall.

Par ailleurs, la bague de sécurité comprend au moins un élément de blocage agencé pour que la bague de sécurité en regard des bras puisse s'appuyer contre les bras lors d'un passage en force de la bague de sécurité sur l'élément de retenue pour monter le bouchon sur le récipient.Furthermore, the safety ring comprises at least one blocking element arranged so that the safety ring facing the arms can press against the arms when the safety ring is forced over the retaining element. to mount the cap on the container.

DESCRIPTION DÉTAILLÉEDETAILED DESCRIPTION

Les figures 1 à 5 représentent plusieurs vues d'un 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.THE figures 1 to 5 represent several views of an embodiment of the screw cap 1 intended to remain attached to a container 2, in particular a bottle, after the container 2 has been opened.

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 non-limiting way, the stopper 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 3 et 5). La paroi cylindrique 3 est configurée pour se trouver alternativement dans une position fermée dans laquelle la paroi cylindrique 3 est vissée sur le col 11 et une position ouverte 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 ( figure 3 And 5 ). The cylindrical wall 3 is configured to be alternately in a closed position in which the cylindrical wall 3 is screwed onto the neck 11 and an open position in which the cylindrical wall 3 is unscrewed from the neck 11 and the neck 11 is open.

De façon non limitative, le filetage 9 agencé sur la surface interne 8 présente un filet possédant un angle de rotation compris entre 540° et 600°.Un utilisateur peut ainsi libérer le bouchon à vis 1 du col 11 avec un nombre réduit de tours par rapport à ce qu'il existe déjà pour un récipient 2 contenant un liquide effervescent. À titre d'exemple, l'angle de rotation du filet est sensiblement égal à 571°.In a non-limiting way, the thread 9 arranged on the internal surface 8 has a thread having an angle of rotation of between 540° and 600°. A user can thus release the screw cap 1 from the neck 11 with a reduced number of turns per compared to what already exists for a container 2 containing an effervescent liquid. By way of example, the angle of rotation of the net is substantially equal to 571°.

La paroi cylindrique 3 comprend en outre une portion formant une languette 15 s'étendant entre un bout d'attache 16 et un bout libre 17 parallèlement à l'axe longitudinal 4. Le bout d'attache 16 est relié à la paroi cylindrique 3 par une charnière 18. Le bout libre 17 peut dépasser l'extrémité 7 de la paroi cylindrique 3. La languette 15 présente des bords longitudinaux 20 parallèles à l'axe longitudinal 4.The cylindrical wall 3 further comprises a portion forming a tongue 15 extending between an attachment end 16 and a free end 17 parallel to the longitudinal axis 4. The attachment end 16 is connected to the cylindrical wall 3 by a hinge 18. The free end 17 can project beyond the end 7 of the cylindrical wall 3. The tongue 15 has longitudinal edges 20 parallel to the longitudinal axis 4.

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.The hinge 18 may correspond to a thinning of the thickness of the cylindrical wall 3 which connects the tongue 15. This thinning thick allows the tongue 15 to be hinged to the cylindrical wall 3 at the thinning.

La languette 15 présente en outre au moins une fente 25A, 25B possédant un deuxième axe longitudinal 27A, 27B sensiblement parallèle à l'axe longitudinal 4. La ou les fentes 25A, 25B peuvent correspondre à des rainures débouchantes. La ou les fentes 25A, 25B présentent une largeur L orthogonale à l'axe longitudinal 27A, 27B (figure 5). La longueur de la ou des fentes est parallèle à l'axe longitudinal 4.The tongue 15 also has at least one slot 25A, 25B having a second longitudinal axis 27A, 27B substantially parallel to the longitudinal axis 4. The slot(s) 25A, 25B may correspond to emerging grooves. Or the slots 25A, 25B have a width L orthogonal to the longitudinal axis 27A, 27B ( figure 5 ). The length of the slot(s) is parallel to the longitudinal axis 4.

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 (ou contre-bague) agencé sur le récipient 2 (figures 3 et 4). 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. La bague de sécurité 12 peut présenter une découpe 30 adaptée pour loger le bout libre 17 de la languette 15, en particulier le bout libre 17 qui dépasse l'extrémité 7 de la paroi cylindrique 3.The cap 1 further comprises a safety ring 12 extending the cylindrical wall 3. The safety ring 12 is intended to be retained at the neck 11 by a retaining element 13 (or counter-ring) arranged on the container 2 ( figures 3 and 4 ). 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. The safety ring 12 may have a cutout 30 adapted to accommodate the free end 17 of the tab 15, in particular the free end 17 which projects beyond the end 7 of the cylindrical wall 3.

La bague de sécurité 12 peut également être retenue par un élément de retenu supplémentaire 37 empêchant que la bague de sécurité 12 descende vers le récipient 2 (figure 3). Ainsi, la bague de sécurité 12 est située entre l'élément de retenu 13 et l'élément de retenu supplémentaire 37.The safety ring 12 can also be retained by an additional retaining element 37 preventing the safety ring 12 from descending towards the container 2 ( picture 3 ). Thus, the safety ring 12 is located between the retaining element 13 and the additional retaining element 37.

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 breakable connection 14. The breakable connection 14 is arranged to break during a first unscrewing of the cylindrical wall 3.

Le bouchon 1 comprend également deux bras 22. Les deux bras 22 sont agencés 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. Par exemple, les bras 22 présentent une élasticité suffisante pour permettre ce déplacement. La languette 15 et les bras 22 retiennent alors la paroi cylindrique 3 à la bague de sécurité 12 qui est retenue au col 11 du récipient 2.The cap 1 also comprises two arms 22. The two arms 22 are arranged to allow the displacement (in translation) of the cylindrical wall 3 along the longitudinal axis 4 during unscrewing of the cylindrical wall 3. For example, the arms 22 have sufficient elasticity to allow this movement. The tongue 15 and the arms 22 retain then the cylindrical wall 3 to the safety ring 12 which is retained at the neck 11 of the container 2.

Chacun des deux bras présente une extrémité 23 et une extrémité 24. L'extrémité 23 de chacun des bras 22 est jointe à un bord longitudinal 20 de la languette 15. Les deux bras bras 22 s'éloignent l'un de l'autre symétriquement de part et d'autre de la languette 15 à partir de l'extrémité 23 vers l'extrémité 24. L'extrémité 24 est reliée à la bague de sécurité 12. Les deux bras 22 sont agencés 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. Par exemple, chacun des bras 22 est dimensionné 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.Each of the two arms has an end 23 and an end 24. The end 23 of each of the arms 22 is joined to a longitudinal edge 20 of the tongue 15. The two arm arms 22 move away from each other symmetrically on either side of the tongue 15 from the end 23 towards the end 24. The end 24 is connected to the safety ring 12. The two arms 22 are arranged to allow movement (in translation) of the cylindrical wall 3 along the longitudinal axis 4 when the cylindrical wall 3 is unscrewed. For example, each of the arms 22 is sized to provide flexibility allowing the cylindrical wall 3 to move in translation along of the longitudinal axis 4 when unscrewing the cylindrical wall 3.

Les bras 22 sont également agencés pour tirer la languette 15 de part et d'autre de la languette 15 au niveau des bords longitudinaux 20. En tirant de part et d'autre de la languette 15, les bras 22 permettent un agrandissement de la largeur L de la ou des fentes 25A, 25B lors d'un déplacement de la paroi cylindrique 3 selon l'axe longitudinal 4 pendant d'un dévissage de la paroi cylindrique 3. Les flèches 40 sur la figure 3 représentent le sens d'étirement des fentes 25A et 25B sous l'action des bras 22. L'action conjuguée de l'élasticité des bras 22 et de l'agrandissement de la largeur L de la ou des fentes 25A, 25B permet d'obtenir une amplitude de déplacement de la paroi cylindrique 3 plus importante qu'une amplitude de déplacement assurée seulement par l'action de l'élasticité des bras 22. En particulier, l'agrandissement d'une fente 25A, 25B correspond à un élargissement de ladite fente 25A, 25B. L'élargissement de la fente 25A, 25B est plus importante à la hauteur d'attache de l'extrémité 23 de chacun des bras 22. Cet élargissement diminue progressivement en s'éloignant de la hauteur d'attache de l'extrémité 23 de chacun des bras 22 (figure 3).The arms 22 are also arranged to pull the tongue 15 on either side of the tongue 15 at the level of the longitudinal edges 20. By pulling on either side of the tongue 15, the arms 22 allow an enlargement of the width L of the slot(s) 25A, 25B when the cylindrical wall 3 moves along the longitudinal axis 4 during unscrewing of the cylindrical wall 3. The arrows 40 on the picture 3 represent the direction of stretching of the slots 25A and 25B under the action of the arms 22. The combined action of the elasticity of the arms 22 and the enlargement of the width L of the slot(s) 25A, 25B makes it possible to obtain an amplitude of displacement of the cylindrical wall 3 greater than an amplitude of displacement ensured only by the action of the elasticity of the arms 22. In particular, the enlargement of a slot 25A, 25B corresponds to an enlargement of said slot 25A, 25B. The widening of the slot 25A, 25B is greater at the height of attachment of the end 23 of each of the arms 22. This widening gradually decreases away from the height of attachment of the end 23 of each arms 22 ( picture 3 ).

Chacun des bras 22 peut prendre différentes formes. À titre d'exemple, sur les figures 1 à 5, chacun des bras 22 comprend une bande. Toutefois, chacun des bras 22 peuvent également comprendre au moins deux bandes. Par ailleurs, les bras 22 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, chacun des bras 22 est dimensionné pour que la force de traction maximale soit sensiblement égale à 35 N.Each of the arms 22 can take different forms. For example, on the figures 1 to 5 , each of the arms 22 comprises a band. However, each of the arms 22 can also comprise at least two bands. Furthermore, the arms 22 are sized to withstand a maximum tensile force sufficient to prevent tearing of the cylindrical wall 3 of the container. Pulling force can be set according to normal use of the cap. The maximum tensile force can be defined according to standards set for the opening of a cap 1. In a non-limiting manner, each of the arms 22 is sized so that the maximum tensile force is substantially equal to 35 N.

Selon un mode de réalisation préféré, la languette 15 présente deux fentes 25A et 25 B dont les axes longitudinaux 27A et 27B sont parallèles entre eux.According to a preferred embodiment, the tab 15 has two slots 25A and 25B whose longitudinal axes 27A and 27B are mutually parallel.

Avantageusement, une fente 25A des deux fentes 25A, 25B est symétrique à l'autre fente 25B des deux fentes 25A, 25B selon une symétrie axiale. Cette symétrie axiale est définie par un axe central 29 de la languette 15 parallèle à l'axe longitudinal 4 (figure 4). L'axe central 29 de la languette 15 correspond à un axe qui sépare, parallèlement à l'axe longitudinal 4, la languette 15 en deux parties égales.Advantageously, one slot 25A of the two slots 25A, 25B is symmetrical to the other slot 25B of the two slots 25A, 25B according to an axial symmetry. This axial symmetry is defined by a central axis 29 of the tongue 15 parallel to the longitudinal axis 4 ( figure 4 ). The central axis 29 of the tongue 15 corresponds to an axis which separates, parallel to the longitudinal axis 4, the tongue 15 into two equal parts.

Chacune des deux fentes 25A, 25B possèdent une forme générale d'accent circonflexe étiré présentant un sommet 32. Le sommet 32 de chacune des deux fentes 25A, 25B est dirigé vers un des bords longitudinaux 20 qui est le plus proche de la fente 25A, 25B considérée. Ainsi, comme représenté sur la figure 1, le sommet 32 de la fente 25A de gauche est dirigé vers le bord longitudinal 20 situé à gauche et le sommet 32 de la fente 25B de droite est dirigé vers le bord longitudinal 20 situé à droite.Each of the two slots 25A, 25B has the general shape of a stretched circumflex accent having a vertex 32. The vertex 32 of each of the two slots 25A, 25B is directed towards one of the longitudinal edges 20 which is closest to the slot 25A, 25B considered. Thus, as shown in the figure 1 , the vertex 32 of the slot 25A on the left is directed towards the longitudinal edge 20 located on the left and the vertex 32 of the slot 25B on the right is directed towards the longitudinal edge 20 located on the right.

Un accent circonflexe possède une forme présentant deux branches 35A, 35B qui se rejoignent au sommet 32. Les branches 35A, 35B peuvent avoir une forme droite ou une forme courbe, au moins en partie. Sur les figures 1 à 5, les deux branches 35A, 35B ont une forme courbe au moins en partie.A circumflex accent has a shape having two branches 35A, 35B which meet at the top 32. The branches 35A, 35B can have a straight shape or a curved shape, at least in part. On the figures 1 to 5 , the two branches 35A, 35B have a curved shape at least in part.

L'extrémité 23 de chacun des bras 22 peut être jointe à un bord longitudinal 20 de la languette 15 entre le bout libre 17 et le bout d'attache 16.The end 23 of each of the arms 22 can be joined to a longitudinal edge 20 of the tongue 15 between the free end 17 and the attachment end 16.

De façon non limitative, l'extrémité 23 de chacun des bras 22 est jointe à un bord longitudinal 20 de la languette 15 à une distance par rapport au bout d'attache 16 comprise entre un tiers et deux tiers de la longueur de la languette 15. Par exemple, l'extrémité 23 de chacun des bras 22 peut être jointe à un bord longitudinal 20 de la languette 15 sensiblement à mi-distance entre le bout libre 17 et le bout d'attache 16In a non-limiting manner, the end 23 of each of the arms 22 is joined to a longitudinal edge 20 of the tongue 15 at a distance relative to the attachment end 16 comprised between one third and two thirds of the length of the tongue 15 For example, the end 23 of each of the arms 22 can be joined to a longitudinal edge 20 of the tab 15 substantially halfway between the free end 17 and the attachment end 16

Avantageusement, les extrémités 23 des deux bras 22 et le sommet 32 de chacune des fentes 25A, 25B sont alignés entre eux, à la même distance entre le bout libre 17 et le bout d'attache 16. Autrement dit, le sommet 32 de chacune des fentes 25A, 25B est en face de l'extrémité 23 du bras 22 le plus proche dudit sommet 32.Advantageously, the ends 23 of the two arms 22 and the top 32 of each of the slots 25A, 25B are aligned with each other, at the same distance between the free end 17 and the attachment end 16. In other words, the top 32 of each slots 25A, 25B is opposite the end 23 of the arm 22 closest to said top 32.

La languette 15 peut aussi comprendre une nervure de renforcement 36 faisant saillie sur la languette 15 vers l'intérieur de la paroi cylindrique 3 (figure 5). La nervure de renforcement 36 est disposée entre les deux fentes 25A, 25B.The tongue 15 may also comprise a reinforcing rib 36 projecting from the tongue 15 towards the inside of the cylindrical wall 3 ( figure 5 ). The reinforcing rib 36 is placed between the two slots 25A, 25B.

Pour que la largeur L de la ou des fentes 25A, 25B puissent s'agrandir, la languette 15 peut avoir une élasticité suffisante pour permettre cet agrandissement. La nervure de renforcement 35 permet d'éviter une déformation de la languette 15 dans une direction parallèle à l'axe longitudinal 4 lorsque la ou les fentes 25A, 25B sont agrandies.For the width L of the slot(s) 25A, 25B to be able to increase, the tab 15 may have sufficient elasticity to allow this enlargement. The reinforcing rib 35 makes it possible to prevent deformation of the tongue 15 in a direction parallel to the longitudinal axis 4 when the slot or slots 25A, 25B are enlarged.

La languette 15 peut également comprendre une butée 34 qui fait saillie sur la languette 15 vers l'extérieur de la paroi cylindrique 3. Cette butée 34 est située au bout libre 17 de la languette 15.

Les deux bras 22 sont configurés pour amener la languette 15 vers la bague de sécurité 12 après le basculement jusqu'à ce que la butée 34 s'appuie contre l'épaulement. La configuration de blocage 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. L'épaulement peut correspondre à une portion de l'élément de retenu 13.The tongue 15 may also include a stop 34 which projects from the tongue 15 towards the outside of the cylindrical wall 3. This stop 34 is located at the free end 17 of the tongue 15. The stop 34 is arranged to bear against a shoulder arranged on the container 2 after a tilting of the tongue 15 when the cylindrical wall 3 is brought into a locking configuration of the stopper 1. The two arms 22 are configured to bring the tongue 15 towards the safety ring 12 after the tilting until the stop 34 bears against the shoulder. The blocking configuration 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. The shoulder may correspond to a portion of the retaining element 13.

La butée 34 peut présenter une forme allongée selon un axe longitudinal qui est orthogonal à l'axe longitudinal 4.The stop 34 may have an elongated shape along a longitudinal axis which is orthogonal to the longitudinal axis 4.

Chacun des bords longitudinaux 20 de la languette 15 peut 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.Each of the longitudinal edges 20 of the tongue 15 can be connected respectively to the cylindrical wall 3 by a tearable line 21. Each tearable 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 tearable line 21 can correspond to a pre-cut line which tears when the cylindrical wall 3 is disengaged from the neck 11 of the container 2 then tilted with respect to the tongue 15, after the first unscrewing of the cylindrical wall 3 .

Dans un autre mode de réalisation, chacun des bords longitudinaux 20 de la languette 15 peut être relié respectivement à la paroi cylindrique 3 par une ligne non déchirable.In another embodiment, each of the longitudinal edges 20 of the tongue 15 can be connected respectively to the cylindrical wall 3 by a non-tearable line.

At least a part of each of the arms 22 thus fills 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 by 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 arms 22 gradually widen starting from the end 24 towards the end 23.

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'hygiène du bouchon 1 lorsque la paroi cylindrique 3 est dans la position fermée avant le premier dévissage de la paroi cylindrique 3.Advantageously, each tearable line 21 also connects each of the arms 22 to the cylindrical wall 3. Thus, the tearable 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 tearable line 21 between each of the arms 22 and the cylindrical wall 3 makes it possible to improve the hygiene of the stopper 1 when the cylindrical wall 3 is in the closed position before the first unscrewing of the cylindrical wall 3.

Dans un autre mode de réalisation, la ligne qui relie chacun les bras 22 à la paroi cylindrique 3 et chacun des bords longitudinaux à la paroi cylindrique 3 est déchirable seulement entre chacun des bras 22 et la paroi cylindrique 3.

La ligne déchirable qui relie chacun des bras 22 à la paroi cylindrique 3 peut comprendre au moins un pontet 38 (figure 7) qui se brise après le premier dévissage de la paroi cylindrique 3 et une première ouverture du col 11 du récipient 2. Un autre pontet 41 peut également relier chacun des bras 22 à la bague de sécurité 12. Ce pontet 41 se brise également après le premier dévissage de la paroi cylindrique 3 et une première ouverture du col 11 du récipient 2.In another embodiment, the line which connects each of the arms 22 to the cylindrical wall 3 and each of the longitudinal edges to the cylindrical wall 3 is tearable only between each of the arms 22 and the cylindrical wall 3. Said line remains non-tearable between each of the longitudinal edges to the cylindrical wall 3. The tear line which connects each of the arms 22 to the cylindrical wall 3 can comprise at least one bridge 38 ( figure 7 ) which breaks after the first unscrewing of the cylindrical wall 3 and a first opening of the neck 11 of the container 2.

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 comes into abutment 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 peut être 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 in correspondence with the cylindrical skirt 31 can be externally raised to increase the outer surface of the stopper 1. The cavity delimited by the cylindrical skirt 31 and the cavity generated by the external raising of the bottom 6 adding together 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 comes into abutment against the non-raised part of the bottom 6, when the cylindrical wall is in the closed position. This makes it possible to seal cap 1.
