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. Le bouchon peut être maintenu dans une position d'ouverture sans intervention d'un utilisateur.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 the neck has been opened. The cap can be held in an open position without user intervention.

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.

Par ailleurs, les bouchons attachés ont l'inconvénient de refermer partiellement le col après ouverture au moins à cause de l'élasticité du dispositif qui attache le bouchon au récipient. En effet, cette élasticité tend à ramener le bouchon vers une position proche d'une position de fermeture. Le col du récipient n'est donc pas complètement ouvert. Afin de garder le col complètement ouvert, l'utilisateur est souvent amené à retenir manuellement le bouchon dans la position d'ouverture afin d'empêcher le bouchon de revenir vers une position de fermeture partielle du col.Furthermore, attached caps have the disadvantage of partially closing the neck after opening, at least because of the elasticity of the device which attaches the cap to the container. Indeed, this elasticity tends to bring the plug back to a position close to a closed position. The neck of the container is therefore not completely open. In order to keep the neck completely open, the user is often required to manually retain the stopper in the open position in order to prevent the stopper from returning to a partially closed position of the neck.

Le document US 2011/0114593 présente un bouchon ayant les caractéristiques techniques du préambule de la revendication 1, permettant de maintenir le bouchon dans une position ouverte. Toutefois, la solution proposée par ce document n'est pas pleinement satisfaisante.The document US 2011/0114593 presents a stopper having the technical characteristics of the preamble of claim 1, making it possible to maintain the stopper in an open position. However, the solution proposed by this document is not entirely satisfactory.

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 maintenu dans sa position ouverte (dans une configuration de blocage) sans intervention de l'utilisateur et à n'importe quel emplacement autour du col du récipient.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 maintained in its open position (in a blocking configuration) without user intervention and at any location. around the neck of the container.

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 :

  • un élément de liaison reliant une zone d'attache de la languette à la bague de sécurité, l'élément de liaison étant agencé pour permettre le déplacement de la paroi cylindrique selon le premier axe longitudinal lors d'un dévissage de la paroi cylindrique,
  • une butée faisant saillie sur la languette vers l'extérieur de la paroi cylindrique entre le bout libre et la zone d'attache de la languette, la languette présentant une portion de blocage entre la butée et le bout libre de la languette, la butée étant agencée pour qu'une partie de l'élément de retenu se loge entre la butée et la portion de blocage après un basculement de la languette quand la paroi cylindrique est amenée dans une configuration de blocage du bouchon, 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.
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 be alternately 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 open, the cylindrical wall comprising a portion forming a tab extending between an attachment end and a free end parallel to the first longitudinal axis, the attachment end being connected to the cylindrical wall by a hinge, the tab having longitudinal edges parallel to the first longitudinal axis,

Ainsi, grâce à la butée qui coince une partie de l'élément de retenu entre ladite butée et la portion de blocage de la languette, le bouchon attaché à son récipient reste en position d'ouverture dans une configuration de blocage sans que l'utilisateur ne soit obligé de retenir manuellement le bouchon dans la position d'ouverture après ouverture du récipient.Thus, thanks to the stopper which wedges part of the retaining element between said stopper and the blocking portion of the tab, the cap attached to its container remains in the open position in a blocking configuration without the user not be obliged to manually retain the stopper in the open position after opening the container.

En outre, la butée présente une forme allongée selon un deuxième axe longitudinal perpendiculaire à un plan contenant la languette.In addition, the abutment has an elongated shape along a second longitudinal axis perpendicular to a plane containing the tongue.

De plus, la butée présente une forme d'arc dans un plan de section perpendiculaire au premier axe longitudinal quand la paroi cylindrique se trouve dans la position fermée.In addition, the abutment has an arc shape in a section plane perpendicular to the first longitudinal axis when the cylindrical wall is in the closed position.

DESCRIPTION DÉTAILLÉEDETAILED DESCRIPTION

Les figures 1 à 4 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 4 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 4). 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 (figures 3 et 4) 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 3 and 4 ). 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 ( figures 3 and 4 ) in which the cylindrical wall 3 is unscrewed from the neck 11 and the neck 11 is open.

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. 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. 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 hinge 18 may 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. The tongue 15 has longitudinal edges 20 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.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 circular projection portion 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 tongue 15.

La bague de sécurité 12 peut également être retenue par un élément de retenu supplémentaire 29 empêchant que la bague de sécurité 12 descende vers le récipient 2 (figures 3 et 4). Ainsi, la bague de sécurité 12 est située entre l'élément de retenu 13 et l'élément de retenu supplémentaire 29.The safety ring 12 can also be retained by an additional retaining element 29 preventing the safety ring 12 from descending towards the container 2 ( figures 3 and 4 ). Thus, the safety ring 12 is located between the retaining element 13 and the additional retaining element 29.

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 un élément de liaison 19. Cet élément de liaison 19 relie une zone d'attache 25 de la languette 15 à la bague de sécurité 12. 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. Par exemple, l'élément de liaison 19 présente une élasticité suffisante pour permettre ce déplacement.The cap 1 also comprises a connecting element 19. This connecting element 19 connects an attachment zone 25 of the tab 15 to the safety ring 12. The connecting element 19 is 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, the connecting element 19 has sufficient elasticity to allow this movement.

Avantageusement, la zone d'attache 25 est située entre le bout d'attache 16 et le bout libre 17.Advantageously, the attachment zone 25 is located between the attachment end 16 and the free end 17.

Par exemple, la zone d'attache 25 peut être située sensiblement à mi-distance entre le bout d'attache 16 et le bout libre 17 de la languette 15.For example, the attachment zone 25 can be located substantially halfway between the attachment end 16 and the free end 17 of the tab 15.

Le bouchon comporte aussi une butée 34 qui fait saillie sur la languette 15 vers l'extérieur de la paroi cylindrique 3 entre le bout libre 17 et la zone d'attache 25 de la languette 15. Par exemple, la butée 34 est adjacente à la zone d'attache 25.The stopper also includes a stop 34 which protrudes from the tongue 15 towards the outside of the cylindrical wall 3 between the free end 17 and the attachment zone 25 of tongue 15. For example, abutment 34 is adjacent to attachment zone 25.

La languette 15 présente une portion de blocage 37 entre la butée 34 et le bout libre 17 de la languette 15. La butée 34 est agencée pour qu'une partie de l'élément de retenu 13 se loge entre la butée 34 et la portion de blocage 37 après un basculement de la languette15 quand la paroi cylindrique 3 est amenée dans une configuration de blocage du bouchon 1 (figure 3). La configuration de blocage représentée sur la figure 3, 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. Le bout libre 17 de la languette 15 forme un point dur autour duquel le basculement est réalisé pour passer vers la configuration de blocage.The tongue 15 has a blocking portion 37 between the abutment 34 and the free end 17 of the tongue 15. The abutment 34 is arranged so that part of the retaining element 13 is housed between the abutment 34 and the portion of blocking 37 after a tilting of the tongue 15 when the cylindrical wall 3 is brought into a blocking configuration of the plug 1 ( picture 3 ). The blocking configuration represented on the picture 3 , 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 free end 17 of the tongue 15 forms a hard point around which the tilting is carried out to pass towards the blocking configuration.

Un coin 38 est ainsi formé entre la butée 34 et la portion de blocage 37. L'élément de retenu 13 se loge dans ce coin 38 après le basculement de la languette 15 pour amener la paroi cylindrique 3 dans la configuration de blocage du bouchon 1. La butée 34 se trouve alors sous l'élément de retenu 13 et non sur l'élément de retenu 13. L'élasticité de l'élément de liaison 19 tendent à empêcher le dégagement de l'élément de retenu 13 du coin formé par la butée 34 et la portion de blocage 37. Lorsque le bouchon 1 est dans la configuration de blocage, l'élément de retenu 13 peut être dégagé par une traction du bouchon 1 par un utilisateur, par exemple.A wedge 38 is thus formed between the abutment 34 and the blocking portion 37. The retaining element 13 is housed in this corner 38 after the tilting of the tab 15 to bring the cylindrical wall 3 into the blocking configuration of the stopper 1 The abutment 34 is then under the retaining element 13 and not on the retaining element 13. The elasticity of the connecting element 19 tends to prevent the release of the retaining element 13 from the corner formed by the stop 34 and the blocking portion 37. When the stopper 1 is in the blocking configuration, the retaining element 13 can be disengaged by pulling the stopper 1 by a user, for example.

Par conséquent, le bouchon 1 peut être amené dans la configuration de blocage à n'importe quel emplacement autour du col 11. De plus, aucun élément du récipient 2, tel que le filetage 10 sur le col 11 du récipient 2, n'empêche le bouchon 1 d'être amené dans la configuration de blocage. En effet, si la butée était agencée pour être amenée sur l'élément de retenu 13 et non sous l'élément de retenu 13, la butée 34 et/ou la portion de blocage 37 auraient pu être gênées par le filetage 10 sur le col 11.Therefore, the stopper 1 can be brought into the locking configuration at any location around the neck 11. In addition, no element of the container 2, such as the thread 10 on the neck 11 of the container 2, prevents the stopper 1 to be brought into the blocking configuration. Indeed, if the abutment was arranged to be brought over the retaining element 13 and not under the retaining element 13, the abutment 34 and/or the blocking portion 37 could have been hindered by the thread 10 on the neck 11.

Avantageusement, la butée 34 présente une forme allongée selon un axe longitudinal perpendiculaire à un plan contenant la languette 15.Advantageously, the stop 34 has an elongated shape along a longitudinal axis perpendicular to a plane containing the tongue 15.

La butée 34 peut présenter une forme d'arc dans un plan de section perpendiculaire à l'axe longitudinal 4 quand la paroi cylindrique 3 se trouve dans la position fermée. La corde de l'arc est comprise dans le plan contenant la languette 15. La forme d'arc correspond, par exemple, à un arc de cercle.The stop 34 can have the shape of an arc in a section plane perpendicular to the longitudinal axis 4 when the cylindrical wall 3 is in the closed position. The chord of the arc is included in the plane containing the tongue 15. The arc shape corresponds, for example, to an arc of a circle.

Par ailleurs, la butée 34 peut présenter un bord libre arrondi 42.Furthermore, the stop 34 may have a rounded free edge 42.

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.

Par ailleurs, l'élément de liaison 19 peut comprend au moins deux bras 22. Chacun des bras présente une extrémité 23 et une extrémité 24. L'extrémité 23 de chacun des bras 22 est jointe à la zone d'attache 25 de la languette 15 à un des bords longitudinaux 20 de la languette 15. Les bras 22 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. Ainsi, l'ensemble comprenant la languette 15 et les bras 22 peut avoir une forme générale de croix dans laquelle la languette 15 correspond à la première barre de la croix et les bras correspondent à la deuxième barre de la croix.Furthermore, the connecting element 19 may comprise at least two arms 22. Each of the arms has an end 23 and an end 24. The end 23 of each of the arms 22 is joined to the attachment zone 25 of the tab 15 to one of the longitudinal edges 20 of the tongue 15. The arms 22 deviate symmetrically on either side of the tongue 15 towards the end 24. The end 24 is connected to the safety ring 12. Thus, the assembly comprising the tongue 15 and the arms 22 may have the general shape of a cross in which the tongue 15 corresponds to the first bar of the cross and the arms correspond to the second bar of the cross.

Par exemple, la zone d'attache 25 correspond à une portion de la languette 15 à laquelle l'élément de liaison 19, en particulier les bras 22, est relié. Cette portion peut être sensiblement rectangulaire. La portion rectangulaire de la zone d'attache 25 peut correspondre sensiblement à un rectangle dont la longueur correspond à la largeur de la languette 15 et la largeur correspond à la largeur d'un bras 22.For example, the attachment zone 25 corresponds to a portion of the tongue 15 to which the connecting element 19, in particular the arms 22, is connected. This portion may be substantially rectangular. The rectangular portion of the attachment zone 25 may substantially correspond to a rectangle, the length of which corresponds to the width of the tab 15 and the width corresponds to the width of an arm 22.

Chacun des bras 22 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 complètement dévissé. La languette 15 et l'élément de liaison 19 retiennent alors la paroi cylindrique 3 à la bague de sécurité 12 qui est retenue au col 11 du récipient 2. 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, les bras 22 sont dimensionnés pour que la force de traction maximale soit sensiblement égale à 35 N.Each of the arms 22 are sized 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 tab 15 and the connecting element 19 then hold the cylindrical wall 3 to the safety ring 12 which is held to the neck 11 of the container 2. 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, the arms 22 are dimensioned so that the maximum tensile force is substantially equal to 35 N.

L'extrémité 7 de la paroi cylindrique 3 peut comprendre une portion de bord présentant une échancrure 26. Les bras 22 sont logés au moins en partie dans l'échancrure 26. Au moins une partie de chacun des bras 22 complètent le bord de l'extrémité 7 de la paroi cylindrique 3 au niveau de l'échancrure 26. Au moins une partie de chacun des bras 22 remplissent ainsi l'espace laissé par l'échancrure 26.The end 7 of the cylindrical wall 3 can comprise an edge portion having an indentation 26. The arms 22 are housed at least in part in the indentation 26. At least a part of each of the arms 22 complete the edge of the end 7 of the cylindrical wall 3 at the level of the notch 26. 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 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 gradually widens starting from end 24 towards 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. Ladite ligne reste non déchirable entre chacun des bords longitudinaux à la paroi cylindrique 3. La ligne déchirable qui relie chacun des bras 22 à la paroi cylindrique 3 peut comprendre au moins un pontet 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 peut également relier chacun des bras 22 à la bague de sécurité 12. Ce pontet 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 tearable line which connects each of the arms 22 to the cylindrical wall 3 can comprise at least one bridge which breaks after the first unscrewing of the cylindrical wall 3 and a first opening of the neck 11 of the container 2. Another bridge can also connect each of the arms 22 to the safety ring 12. This bridge also breaks after the first unscrewing of the cylindrical wall 3 and a first opening of the neck 11 of the container 2.

La bague de sécurité 12 peut comprendre au moins un élément de blocage 28. Ce ou ces éléments de blocage 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 1 et 2 montrent des éléments de blocage 28 repartis sur la bague de sécurité 12 en regard des bras 22. Le ou les éléments de blocage 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 blocking element 28. This or these blocking elements 28 are arranged so that the safety ring 12 facing the arms 22 can press against the arms 22 during a passage in force of the security ring 12 on the retainer 13 to mount the stopper 1 on the container 2 on a bottling line. THE figures 1 and 2 show blocking elements 28 distributed over the safety ring 12 opposite the arms 22. The blocking element(s) 28 may correspond to one or more projections of substantially parallelepipedal shape in one piece with the safety ring 12.

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 may further comprise a cylindrical skirt 31 for internal stopper carried by the bottom 6 and configured to penetrate into the neck 11 of the container 2 when screwing the cylindrical wall 3 to 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. La jupe cylindrique 31 a pour rôle l'étanchéité du col 11.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. The cylindrical skirt 31 has the role of sealing the neck 11.

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.

Le bout d'attache 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 attachment end 16 connecting the tongue 15 to the cylindrical wall 3 can 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 peut comprendre un bord libre présentant une échancrure (non représentée) en regard de la languette 15. Cette échancrure 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 may include a free edge having a notch (not shown) facing the tongue 15. This notch makes it easier to disengage the cylindrical wall 3 from the neck 11 of the container 2 after it has been unscrewed. It also facilitates the positioning of the cylindrical wall 3 on the neck 11 of the container 2 before the screwing of the cylindrical wall 3 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. Ces reliefs de préhension 33 facilitent le dévissage et le revissage du bouchon 1.The cylindrical wall 3 may have an outer surface comprising gripping reliefs 33. In a non-limiting manner, the gripping reliefs correspond to diametrical fins regularly distributed over the outer surface of the cylindrical wall 3. These gripping reliefs 33 facilitate the unscrewing and screwing back of the cap 1.

La languette 15 peut comprendre des nervures 27 faisant saillie sur la languette 15 vers l'extérieur de la paroi cylindrique 3 (figures 1 et 2). Ces nervures 27 prennent naissance au niveau de la charnière 18 et s'étendent sensiblement jusqu'à la zone d'attache 25. Ces nervures 27 peuvent participer à la rigidité de la languette 15 et à la préhension du bouchon 1 pour faciliter le dévissage et le revissage du bouchon 1. La rigidité apportée par les nervures 27 participe à faciliter l'installation du bouchon à vis 1 au col 11. Les figures 1 et 2 présentent une languette 15 comprenant quatre nervures 27 parallèles.The tongue 15 may comprise ribs 27 projecting from the tongue 15 towards the outside of the cylindrical wall 3 ( figures 1 and 2 ). These ribs 27 originate at the level of the hinge 18 and extend substantially as far as the attachment zone 25. These ribs 27 can contribute to the rigidity of the tab 15 and to the gripping of the cap 1 to facilitate unscrewing and the screwing of the cap 1. The rigidity provided by the ribs 27 contributes to facilitating the installation of the screw cap 1 to the neck 11. The figures 1 and 2 have a tongue 15 comprising four parallel ribs 27.

Selon un mode de réalisation, la bague de sécurité 12 comprend une partie circulaire externe et une partie circulaire interne.

Pour chaque mode de réalisation, la partie circulaire interne peut être continue tout autour de la partie circulaire externe. Elle peut être également discontinue. Lorsqu'elle est discontinue, elle comprend une pluralité de pétales tout autour de la partie circulaire externe. Chacune des pétales jouent le rôle d'un harpon qui retient la bague de sécurité 12 retenue au col 11 par l'élément de retenue 13 agencé sur le récipient 2.For each embodiment, the inner circular part can be continuous all around the outer circular part. It can also be discontinuous. When it is discontinuous, it comprises a plurality of petals all around the outer circular part. Each of the petals play the role of a harpoon which retains the safety ring 12 retained at the neck 11 by the retaining element 13 arranged on the container 2.

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 suitable diameter for any screw container neck 11 . 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 screw neck 11 of 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 non-limiting 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 dimensioned 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. Similarly, the thread 9 may have threads that are more or less tight and/or more or less thick.
