Definitions

  • the invention relates to a stopper device which is equipped with a stopper and makes it possible to keep said stopper attached to the neck of a container, which avoids losing the stopper in nature.
  • the document WO20193821 discloses such a stopper device for keeping the stopper attached to the neck of a container.
  • the closure device comprises a lower ring which is intended to be mounted fixed axially on the neck of the container and movable in rotation relative to the latter.
  • the lower ring comprises a first sector which comprises hooking elements which protrude radially towards the inside of the lower ring and are intended to be arranged below a collar for hooking the neck so as to retain the ring below the neck of the container.
  • the lower ring also comprises a second sector which is hinged to the first sector and can thus pivot relative to the first sector between a lowered position in which the second sector is arranged below the attachment flange and a raised position in which the second sector is arranged above the attachment flange.
  • the stopper device also comprises a stopper having an upper wall and a peripheral skirt having a thread intended to cooperate with a thread of the neck.
  • the cap is articulated on the second sector of the lower ring by means of two slats which connect the peripheral skirt and the second sector.
  • the second sector of the lower ring pivots relative to the first sector to the raised position so as to allow axial movement, upwards of the cap, from a closed position to a closed position. released.
  • the two slats allow the stopper to switch between said released position and an open tilted position.
  • the plugging device also comprises a blocking device making it possible to block the plug in the tilted open position.
  • the plugging device comprises a tab disposed between the two elastic blades and extending upwards from the lower ring and a cleat projecting radially outwards from the outer peripheral skirt, the cleat being arranged to bear against the tab when rotating the cap. Due to the support of the cleat against the tongue, the elastic strips are subjected to a tensile force which increases during a first part of the movement of the stopper from the released position towards the open tilted position up to an intermediate unstable position. Then, the tensile force to which the elastic strips are subjected decreases from said intermediate unstable position. This allows the stopper to be locked in the tilted open position.
  • the cleat in order to be able to bear against the tab when the stopper is in the open tilted position, the cleat has a relatively large radial dimension.
  • a cleat having too large a radial dimension is likely to harm the reliability and the efficiency of bottling operations during which the closure devices are in particular transported on conveyors before being placed on the necks of the containers.
  • Too prominent a stopper is also likely to interfere with the user when handling the stopper.
  • a cleat consisting of a substantial quantity of plastic material is liable to cause injection problems during the manufacture of the stopper.

  • the local increase in the thickness of the lower ring at least at the projecting portion makes it possible to reduce the radial dimension of the cleat accordingly.
  • This is particularly advantageous insofar as a stopper having too large a radial dimension is likely to harm the reliability and efficiency of bottling operations, is likely to bother the user when handling the cork and is also likely cause injection problems.
  • This increase in thickness also makes it possible to increase the stiffness of the protruding portion and to further ensure the reliability and robustness of the locking device.

Description

[Domaine technique [ Technical field

L'invention se rapporte à un dispositif de bouchage qui est équipé d'un bouchon et permet de garder ledit bouchon attaché au col d'un récipient, ce qui évite de perdre le bouchon dans la nature.The invention relates to a stopper device which is equipped with a stopper and makes it possible to keep said stopper attached to the neck of a container, which avoids losing the stopper in nature.

Arrière-plan technologiqueTechnology background

Le document WO20193821 divulgue un tel dispositif de bouchage permettant de garder le bouchon attaché au col d'un récipient. Le dispositif de bouchage comporte une bague inférieure qui est destinée à être montée fixe axialement sur le col du récipient et mobile en rotation par rapport à celui-ci. La bague inférieure comporte un premier secteur qui comporte des éléments d'accrochage qui font saillie radialement vers l'intérieur de la bague inférieure et sont destinés à être disposés en-dessous d'une collerette d'accrochage du col de manière à retenir la bague inférieure au col du récipient. La bague inférieure comporte également un deuxième secteur qui est articulé au premier secteur et peut ainsi pivoter par rapport au premier secteur entre une position abaissée dans laquelle le deuxième secteur est disposé en-dessous de la collerette d'accrochage et une position relevée dans laquelle le deuxième secteur est disposé au-dessus de la collerette d'accrochage. Le dispositif de bouchage comporte également un bouchon présentant une paroi supérieure et une jupe périphérique présentant un filetage destiné à coopérer avec un filetage du col. Le bouchon est articulé sur le deuxième secteur de la bague inférieure au moyen de deux lamelles qui relient la jupe périphérique et le deuxième secteur. Ainsi, lorsque le bouchon est dévissé, le deuxième secteur de la bague inférieure pivote par rapport au premier secteur jusqu'à la position relevée de sorte à autoriser un mouvement axial, vers le haut du bouchon, d'une position de fermeture vers une position libérée. De plus, les deux lamelles permettent au bouchon de basculer entre ladite position libérée et une position basculée ouverte.The document WO20193821 discloses such a stopper device for keeping the stopper attached to the neck of a container. The closure device comprises a lower ring which is intended to be mounted fixed axially on the neck of the container and movable in rotation relative to the latter. The lower ring comprises a first sector which comprises hooking elements which protrude radially towards the inside of the lower ring and are intended to be arranged below a collar for hooking the neck so as to retain the ring below the neck of the container. The lower ring also comprises a second sector which is hinged to the first sector and can thus pivot relative to the first sector between a lowered position in which the second sector is arranged below the attachment flange and a raised position in which the second sector is arranged above the attachment flange. The stopper device also comprises a stopper having an upper wall and a peripheral skirt having a thread intended to cooperate with a thread of the neck. The cap is articulated on the second sector of the lower ring by means of two slats which connect the peripheral skirt and the second sector. Thus, when the cap is unscrewed, the second sector of the lower ring pivots relative to the first sector to the raised position so as to allow axial movement, upwards of the cap, from a closed position to a closed position. released. In addition, the two slats allow the stopper to switch between said released position and an open tilted position.

Le dispositif de bouchage comporte également un dispositif de blocage permettant de bloquer le bouchon dans la position basculée ouverte. Le dispositif de bouchage comporte une languette disposée entre les deux lamelles élastiques et s'étendant vers le haut depuis la bague inférieure et un taquet faisant saillie radialement vers l'extérieur depuis la jupe périphérique externe, le taquet étant agencé pour venir en appui contre la languette lors du pivotement du bouchon. En raison de l'appui du taquet contre la languette, les lamelles élastiques sont soumises à une force de traction qui augmente durant une première partie du mouvement du bouchon de la position libérée vers la position basculée ouverte jusqu'à une position instable intermédiaire. Puis, la force de traction à laquelle sont soumises les lamelles élastiques décroit à partir de ladite position instable intermédiaire. Ceci permet de bloquer le bouchon dans la position basculée ouverte.The plugging device also comprises a blocking device making it possible to block the plug in the tilted open position. The plugging device comprises a tab disposed between the two elastic blades and extending upwards from the lower ring and a cleat projecting radially outwards from the outer peripheral skirt, the cleat being arranged to bear against the tab when rotating the cap. Due to the support of the cleat against the tongue, the elastic strips are subjected to a tensile force which increases during a first part of the movement of the stopper from the released position towards the open tilted position up to an intermediate unstable position. Then, the tensile force to which the elastic strips are subjected decreases from said intermediate unstable position. This allows the stopper to be locked in the tilted open position.

Un tel dispositif de bouchage n'est pas pleinement satisfaisant.Such a plugging device is not fully satisfactory.

En particulier, pour pouvoir venir en appui contre la languette lorsque le bouchon est en position basculée ouverte, le taquet présente une dimension radiale relativement importante. Or, un taquet ayant une dimension radiale trop importante est susceptible de nuire à la fiabilité et au rendement des opérations d'embouteillage au cours desquelles les dispositifs de bouchage sont notamment transportés sur des convoyeurs avant d'être mis en place sur les cols des récipients. Un taquet trop proéminent est également susceptible de gêner l'utilisateur lorsqu'il manipule le bouchon. Enfin, un taquet constitué d'une quantité de matière plastique conséquente est susceptible d'engendrer des problèmes d'injection lors de la fabrication du bouchon.In particular, in order to be able to bear against the tab when the stopper is in the open tilted position, the cleat has a relatively large radial dimension. However, a cleat having too large a radial dimension is likely to harm the reliability and the efficiency of bottling operations during which the closure devices are in particular transported on conveyors before being placed on the necks of the containers. . Too prominent a stopper is also likely to interfere with the user when handling the stopper. Finally, a cleat consisting of a substantial quantity of plastic material is liable to cause injection problems during the manufacture of the stopper.

RésuméSummary

Une idée à la base de l'invention est de proposer un dispositif de bouchage équipé d'un bouchon attaché au col du récipient apte à être vissé sur le col du récipient et qui permette de bloquer de manière fiable le bouchon dans une position basculée ouverte dans laquelle il ne gêne pas le déversement du contenu du récipient tout en limitant la dimension des éléments faisant saillie vers l'extérieur du bouchon.An idea at the base of the invention is to propose a stopper device equipped with a stopper attached to the neck of the container capable of being screwed onto the neck of the container and which makes it possible to reliably block the stopper in a tilted open position. in which it does not interfere with the pouring out of the contents of the container while limiting the size of the elements projecting outwardly from the stopper.

Une autre idée à la base de l'invention est d'obtenir un angle d'ouverture important du bouchon en position basculée ouverte afin de ne pas gêner le déversement du contenu du récipient.Another idea at the basis of the invention is to obtain a large opening angle of the cap in the open tilted position so as not to interfere with the pouring out of the contents of the container.

Selon un mode de réalisation, l'invention fournit un dispositif de bouchage destiné à être fixé sur un col d'un récipient comportant un orifice de distribution, un filetage hélicoïdal et une collerette d'accrochage, le dispositif de bouchage comportant :

  • une bague inférieure destinée à être montée fixe axialement sur le col et mobile en rotation autour d'un axe X, ladite bague inférieure comportant un premier secteur qui comporte des zones d'accrochage comportant chacune au moins un élément d'accrochage qui fait saillie radialement vers l'intérieur de la bague inférieure et est destiné à être disposé en-dessous de la collerette d'accrochage de manière à retenir axialement la bague inférieure sur le col du récipient et un deuxième secteur, le premier secteur et le deuxième secteur de la bague inférieure étant articulés l'un à l'autre de manière à ce que le deuxième secteur pivote par rapport au premier secteur entre une position abaissée dans laquelle le deuxième secteur est destiné à être disposé en-dessous de la collerette d'accrochage et une position relevée dans laquelle le deuxième secteur est destiné à être disposé au moins en partie au-dessus de la collerette d'accrochage,
  • un bouchon comportant une paroi supérieure et une jupe périphérique externe, la jupe périphérique externe présentant un filetage hélicoïdal destiné à coopérer avec le filetage hélicoïdal du col de sorte à permettre le déplacement du bouchon entre une position de fermeture et une position libérée dans laquelle le filetage hélicoïdal du bouchon n'est plus en prise avec le filetage hélicoïdal du col ;
• un dispositif d'articulation comportant deux lamelles reliant la jupe périphérique externe et le deuxième secteur et configurées pour permettre au bouchon de pivoter entre la position libérée et une position basculée ouverte dans laquelle le bouchon est dégagé de l'orifice de distribution du col; le deuxième secteur de la bague inférieure étant apte à être positionné dans la position abaissée lorsque le bouchon est dans la position basculée ouverte ;
le dispositif de bouchage comportant en outre un dispositif de blocage configuré pour bloquer le bouchon lorsqu'il est dans la position basculée ouverte, ledit dispositif de blocage comportant :
  • un taquet qui fait saillie radialement vers l'extérieur, depuis la jupe périphérique externe, et est disposé circonférentiellement entre les deux lamelles du dispositif d'articulation; et • une portion en saillie qui fait saillie axialement depuis une portion centrale du deuxième secteur de la bague inférieure, entre les deux lamelles du dispositif d'articulation ;
  • le taquet et la portion en saillie étant configurés de telle sorte que, lorsque le bouchon est en position basculée ouverte et le deuxième secteur de la bague inférieure est dans la position abaissée, le taquet est en appui contre la portion en saillie,
et dans lequel la jupe périphérique externe comporte un talon faisant saillie axialement vers la portion en saillie entre les deux lamelles, la portion en saillie présentant une épaisseur radiale ε1 supérieure à une épaisseur radiale ε2 du premier secteur de la bague inférieure hors des zones d'accrochage et présentant des évidements débouchant en regard du talon.According to one embodiment, the invention provides a closure device intended to be fixed on a neck of a container comprising a dispensing orifice, a helical thread and a fastening flange, the closure device comprising:
  • a lower ring intended to be mounted fixed axially on the neck and movable in rotation around an axis X, said lower ring comprising a first sector which comprises attachment zones each comprising at least one attachment element which projects radially towards the inside of the lower ring and is intended to be arranged below the attachment flange so as to retain the lower ring axially on the neck of the container and a second sector, the first sector and the second sector of the lower ring being articulated to one another so that the second sector pivots with respect to the first sector between a lowered position in which the second sector is intended to be arranged below the attachment flange and a raised position in which the second sector is intended to be arranged at least partly above the attachment flange,
  • a cap comprising an upper wall and an outer peripheral skirt, the outer peripheral skirt having a helical thread intended to cooperate with the helical thread of the neck so as to allow movement of the cap between a closed position and a released position in which the thread thread of the cap is no longer engaged with the helical thread of the neck;
• a hinge device comprising two slats connecting the outer peripheral skirt and the second sector and configured to allow the cap to pivot between the released position and an open tilted position in which the cap is disengaged from the neck dispensing orifice; the second sector of the lower ring being able to be positioned in the lowered position when the cap is in the open tilted position;
the plugging device further comprising a blocking device configured to block the plug when it is in the open tilted position, said blocking device comprising:
  • a cleat which projects radially outwards from the outer peripheral skirt and is disposed circumferentially between the two blades of the hinge device; and • a projecting portion which projects axially from a central portion of the second sector of the lower ring, between the two strips of the hinge device;
  • the cleat and the protruding portion being configured such that, when the plug is in the open tilted position and the second sector of the lower ring is in the lowered position, the cleat bears against the protruding portion,
and in which the outer peripheral skirt comprises a heel projecting axially towards the projecting portion between the two strips, the projecting portion having a radial thickness ε1 greater than a radial thickness ε2 of the first sector of the lower ring outside the areas of attachment and having recesses opening opposite the heel.

Ainsi, l'augmentation locale de l'épaisseur de la bague inférieure au moins au niveau de la portion en saillie permet de diminuer en conséquence la dimension radiale du taquet. Ceci est particulièrement avantageux dans la mesure où un taquet ayant une dimension radiale trop importante est susceptible de nuire à la fiabilité et au rendement des opérations d'embouteillage, est susceptible de gêner l'utilisateur lorsqu'il manipule le bouchon et est en outre susceptible d'engendrer des problèmes d'injection.Thus, the local increase in the thickness of the lower ring at least at the projecting portion makes it possible to reduce the radial dimension of the cleat accordingly. This is particularly advantageous insofar as a stopper having too large a radial dimension is likely to harm the reliability and efficiency of bottling operations, is likely to bother the user when handling the cork and is also likely cause injection problems.

Cette augmentation d'épaisseur permet également d'augmenter la raideur de la portion en saillie et d'assurer encore davantage la fiabilité et la robustesse du dispositif de blocage.This increase in thickness also makes it possible to increase the stiffness of the protruding portion and to further ensure the reliability and robustness of the locking device.

De plus, les évidements ménagés dans la portion en saillie sont susceptibles d'être formés, lors du moulage du dispositif de bouchage, par des nervures de renforcement d'une lame en acier du moule utilisé. Ainsi, de tels évidements permettent d'augmenter la dimension radiale de la portion en saillie sans augmenter la hauteur de l'interstice entre la portion en saillie et le talon ni risquer de détériorer ladite lame en acier.In addition, the recesses made in the projecting portion are likely to be formed, during the molding of the plugging device, by reinforcing ribs of a steel blade of the mold used. Thus, such recesses make it possible to increase the radial dimension of the protruding portion without increasing the height of the gap between the protruding portion and the heel or risking damaging said steel blade.

Selon d'autres modes de réalisation avantageux, un tel dispositif de bouchage peut présenter une ou plusieurs des caractéristiques suivantes.According to other advantageous embodiments, such a closure device may have one or more of the following characteristics.

Selon un mode de réalisation, l'épaisseur radiale ε1 est comprise entre 0,4 et 2 mm, de préférence comprise entre 1 et 2 mm .According to one embodiment, the radial thickness ε1 is between 0.4 and 2 mm, preferably between 1 and 2 mm.

Selon un mode de réalisation, le taquet présente une face externe qui s'étend axialement dans l'alignement d'une face externe de la portion centrale du deuxième secteur de la bague inférieure. Ainsi, la présence de surfaces anguleuses entre la portion en saillie et la portion centrale de la bague inférieure est évitée ce qui permet notamment de simplifier la forme du moule destiné à la réalisation d'un tel dispositif de bouchage.According to one embodiment, the cleat has an outer face which extends axially in alignment with an outer face of the central portion of the second sector of the lower ring. Thus, the presence of angular surfaces between the projecting portion and the central portion of the lower ring is avoided, which makes it possible in particular to simplify the shape of the mold intended for the production of such a plugging device.

Selon un mode de réalisation, le deuxième secteur de la bague inférieure présente deux extrémités qui sont chacune reliées au premier secteur de la bague inférieure et présente une face externe qui s'éloigne progressivement de l'axe X depuis chacune des deux extrémités du deuxième secteur vers la portion centrale dudit deuxième secteur. Selon un mode de réalisation, le deuxième secteur de la bague inférieure présente entre chacune de ses extrémités et la portion centrale du deuxième secteur, une face externe qui est sensiblement inscrite dans une portion d'ellipse de centre X. Ceci permet d'éviter la présence de surfaces anguleuses susceptibles de blesser l'utilisateur et de simplifier la forme du moule destinée au moulage d'un tel dispositif de bouchage.According to one embodiment, the second sector of the lower ring has two ends which are each connected to the first sector of the lower ring and has an outer face which gradually moves away from the axis X from each of the two ends of the second sector towards the central portion of said second sector. According to one embodiment, the second sector of the lower ring has, between each of its ends and the central portion of the second sector, an outer face which is substantially inscribed in a portion of an ellipse with center X. This makes it possible to avoid the presence of angular surfaces liable to injure the user and to simplify the shape of the mold intended for the molding of such a closure device.

Selon un mode de réalisation, les lamelles sont symétriques l'une à l'autre par rapport à un plan radial de symétrie et la face externe de la portion en saillie et la face externe de la portion centrale du deuxième secteur de la bague inférieure s'étendent dans un plan qui est perpendiculaire audit plan radial de symétrie.According to one embodiment, the slats are symmetrical to each other with respect to a radial plane of symmetry and the outer face of the projecting portion and the outer face of the central portion of the second sector of the lower ring s extend in a plane which is perpendicular to said radial plane of symmetry.

Selon un mode de réalisation, le taquet présente une extrémité qui s'étend dans un plan qui est perpendiculaire audit plan radial de symétrie et est parallèle à la face externe de la portion en saillie.According to one embodiment, the cleat has one end which extends in a plane which is perpendicular to said radial plane of symmetry and is parallel to the outer face of the projecting portion.

Selon un mode de réalisation, l'interstice ménagé axialement entre le talon et la portion en saillie présente une hauteur inférieure à 0.6 mm, et de préférence comprise 0.3 et 0.6mm.According to one embodiment, the gap provided axially between the heel and the projecting portion has a height of less than 0.6 mm, and preferably between 0.3 and 0.6 mm.

Selon un mode réalisation, le taquet présente une surface supérieure en biseau orientée de telle sorte que le taquet présente une hauteur qui diminue depuis la jupe périphérique externe vers une extrémité du taquet, le taquet étant configuré de telle sorte que, en position basculée ouverte, la surface supérieure du taquet soit en appui contre la portion en saillie. Ceci permet d'augmenter l'angle d'ouverture du bouchon.According to one embodiment, the cleat has a bevelled upper surface oriented such that the cleat has a height which decreases from the outer peripheral skirt towards one end of the cleat, the cleat being configured such that, in the open tilted position, the upper surface of the cleat bears against the projecting portion. This makes it possible to increase the opening angle of the stopper.

Selon un mode de réalisation, le taquet présente une extrémité qui présente une hauteur inférieure à 1 mm, de préférence inférieure 0,8 mm, par exemple de l'ordre de 0.6 mm.According to one embodiment, the cleat has an end which has a height of less than 1 mm, preferably less than 0.8 mm, for example of the order of 0.6 mm.

Selon un mode de réalisation, le premier secteur comporte une zone avant qui est diamétralement opposée au deuxième secteur et deux zones d'accrochage dans lesquelles sont positionnées les éléments d'accrochage et qui sont respectivement situées de part et d'autre de la zone avant entre ladite zone avant et le deuxième secteur.According to one embodiment, the first sector comprises a front zone which is diametrically opposed to the second sector and two attachment zones in which the attachment elements are positioned and which are respectively located on either side of the front zone between said front zone and the second sector.

Selon un mode de réalisation, la zone avant du premier secteur est dépourvue d'éléments d'accrochage.According to one embodiment, the front zone of the first sector has no attachment elements.

Selon un mode de réalisation, les éléments d'accrochage sont exclusivement disposés dans les deux zones d'accrochage.According to one embodiment, the attachment elements are exclusively arranged in the two attachment zones.

Selon un mode de réalisation, la portion en saillie fait saillie au-delà d'une limite inférieure de la jupe périphérique externe.According to one embodiment, the projecting portion projects beyond a lower limit of the outer peripheral skirt.

Selon un mode de réalisation, les lamelles et le dispositif de blocage sont configurés de telle sorte que, lors du mouvement de pivotement du bouchon entre la position libérée et la position basculée ouverte, les lamelles soient soumises à une force de traction qui augmente jusqu'à une position instable intermédiaire puis qui décroit de ladite position instable intermédiaire vers la position basculée ouverte.According to one embodiment, the slats and the locking device are configured such that, during the pivoting movement of the cap between the released position and the open tilted position, the slats are subjected to a tensile force which increases up to to an intermediate unstable position which then decreases from said intermediate unstable position towards the open tilted position.

Selon un mode de réalisation, le dispositif de bouchage est venu de moulage en une seule pièce.According to one embodiment, the closure device is molded in one piece.

Selon un mode de réalisation, la bague inférieure est reliée à la jupe périphérique externe par des ponts frangibles.According to one embodiment, the lower ring is connected to the outer peripheral skirt by frangible bridges.

Selon un mode de réalisation, lorsque le bouchon est dans la position basculée ouverte et que le deuxième secteur de la bague inférieure est dans la position abaissée, l'angle d'ouverture du bouchon est supérieur à 120°, de préférence supérieure à 180 °, avantageusement supérieure à 190 ° et par exemple de l'ordre de 200°.According to one embodiment, when the cap is in the open tilted position and the second sector of the lower ring is in the lowered position, the opening angle of the cap is greater than 120°, preferably greater than 180° , advantageously greater than 190° and for example of the order of 200°.

Selon un mode de réalisation, la jupe périphérique externe comporte une portion échancrée et les lamelles élastiques rejoignent ladite jupe périphérique externe dans ladite portion échancrée. Un tel agencement permet de ménager des lamelles élastiques de longueur suffisante tout en limitant les dimensions des interstices, ménagés entre le bouchon et la bague inférieure, et susceptibles d'autoriser le passage de poussières ou de corps extérieurs indésirables.According to one embodiment, the outer peripheral skirt comprises a notched portion and the elastic blades join said outer peripheral skirt in said notched portion. Such an arrangement makes it possible to provide elastic strips of sufficient length while limiting the dimensions of the interstices, provided between the stopper and the lower ring, and capable of allowing the passage of dust or undesirable external bodies.

Selon un mode de réalisation, l'invention fournit également un ensemble comportant un dispositif de bouchage précité et un récipient équipé d'un col, le col comportant un orifice, un filetage hélicoïdal et une collerette d'accrochage, les éléments d'accrochage de la bague inférieure étant disposés en-dessous de la collerette d'accrochage de manière à retenir axialement la bague inférieure sur le col du récipient.According to one embodiment, the invention also provides an assembly comprising an aforementioned closure device and a container equipped with a neck, the neck comprising an orifice, a helical thread and a fastening collar, the fastening elements of the lower ring being arranged below the attachment flange so as to retain the lower ring axially on the neck of the container.

Selon d'autres modes de réalisation avantageux, un tel ensemble peut présenter une ou plusieurs des caractéristiques suivantes.According to other advantageous embodiments, such an assembly may have one or more of the following characteristics.

Selon un mode de réalisation, le taquet et la portion en saillie sont configurés de telle sorte que, lorsque le bouchon est en position basculée ouverte et le deuxième secteur de la bague inférieure est dans la position abaissée, la portion en saillie est serrée entre le taquet et la collerette d'accrochage.According to one embodiment, the cleat and the protruding portion are configured such that, when the cap is in the open tilted position and the second sector of the lower ring is in the lowered position, the protruding portion is clamped between the cleat and the attachment collar.

Grâce à un tel agencement, le dispositif de blocage garantit un blocage robuste, avec un angle important, du bouchon dans sa position basculée ouverte.Thanks to such an arrangement, the blocking device guarantees robust blocking, with a large angle, of the plug in its open tilted position.

Selon un mode de réalisation, le taquet et la portion en saillie sont configurés de telle sorte que, lorsque le bouchon est en position basculée ouverte et la deuxième section de la bague inférieure est dans la position abaissée, le taquet et la portion en saillie sont en contact l'un contre l'autre dans une zone située dans le plan de la collerette d'accrochage.According to one embodiment, the cleat and the protruding portion are configured such that, when the cap is in the tilted open position and the second section of the lower ring is in the lowered position, the cleat and the protruding portion are in contact against each other in a zone located in the plane of the attachment collar.

Description des modes de réalisationDescription of embodiments

Dans la description et les figures, l'axe X correspond à l'axe de rotation du bouchon 1 du dispositif de bouchage lorsque celui-ci est vissé sur le col 2 du récipient. Par convention, l'orientation « radiale » est dirigée orthogonalement à l'axe X et l'orientation axiale est dirigée parallèlement à l'axe X. Les termes « externe » et « interne » sont utilisés pour définir la position relative d'un élément par rapport à un autre, par référence à l'axe X, un élément proche de l'axe X est ainsi qualifié d'interne par opposition à un élément externe situé radialement en périphérie.In the description and the figures, the axis X corresponds to the axis of rotation of the stopper 1 of the stopper device when the latter is screwed onto the neck 2 of the container. By convention, the "radial" orientation is directed orthogonal to the X axis and the axial orientation is directed parallel to the X axis. The terms "external" and "internal" are used to define the relative position of a element with respect to another, with reference to the X axis, an element close to the X axis is thus qualified as internal as opposed to an external element located radially on the periphery.

Les termes « supérieur » et « inférieur » sont utilisés pour définir la position relative d'un élément par rapport à un autre par référence à une position dans laquelle l'orifice 3 du col 2 est dirigé vers le haut et le bouchon 1 est en position de fermeture sur le col 2 du récipient, un élément destiné à être placé plus bas étant désigné par inférieur et un élément destiné à être placé plus haut étant désigné par supérieur. Les termes « avant » et « arrière » sont utilisés pour définir la position relative d'un élément par rapport à un autre le long d'un diamètre perpendiculaire à l'axe X.The terms "upper" and "lower" are used to define the relative position of one element with respect to another with reference to a position in which the orifice 3 of the neck 2 is directed upwards and the stopper 1 is in closed position on the neck 2 of the container, an element intended to be placed lower being designated by lower and an element intended to be placed higher being designated by upper. The terms "front" and "back" are used to define the relative position of one element to another along a diameter perpendicular to the X axis.

En relation avec les figures 1 à 7, il est décrit ci-dessous un ensemble comprenant un dispositif de bouchage et un récipient équipé d'un col 2, représenté sur les figures 2 à 5.In relation to the figures 1 to 7 , there is described below an assembly comprising a closure device and a container equipped with a neck 2, represented on the figures 2 to 5 .

Comme représenté notamment sur la figure 2, le col 2 du récipient comporte une extrémité supérieure dans laquelle est ménagé un orifice 3 permettant de déverser le contenu du récipient. Le col 2 du récipient comporte un collier de support 4 qui fait saillie radialement vers l'extérieur et une collerette d'accrochage 5 qui fait également saillie radialement vers l'extérieur et qui est disposée axialement entre le collier de support 4 et l'orifice 3. Une portion cylindrique est ménagée axialement entre le collier de support 4 et l'orifice 3. Par ailleurs, le col 2 comporte, positionné axialement entre la collerette d'accrochage 5 et l'orifice 3, un filetage hélicoïdal 6 formé d'une série de nervures hélicoïdales, faisant saillie radialement vers l'extérieur depuis une surface externe du col 2. Le filetage hélicoïdal 6 est destiné à coopérer avec un filetage hélicoïdal 7 complémentaire, représenté sur les figures 5 et 6, formé d'une série de nervures hélicoïdales qui sont ménagées dans le bouchon 1 du dispositif de bouchage. Selon un mode de réalisation, le filetage hélicoïdal 6 ménagé dans le col 2 ainsi que le filetage hélicoïdal 7 ménagé dans le bouchon 1 sont interrompus. En d'autres termes, les nervures hélicoïdales adjacentes sont séparées par un espace formant évent et permettant notamment d'évacuer le gaz présent à l'intérieur du récipient alors que le bouchon 1 est toujours en prise sur le col 2.As shown in particular on the figure 2 , the neck 2 of the container has an upper end in which is formed an orifice 3 allowing the contents of the container to be poured out. The neck 2 of the container comprises a support collar 4 which projects radially outwards and a fastening flange 5 which also projects radially outwards and which is arranged axially between the support collar 4 and the orifice 3. A cylindrical portion is provided axially between the support collar 4 and the orifice 3. Furthermore, the neck 2 comprises, positioned axially between the attachment flange 5 and the orifice 3, a helical thread 6 formed of a series of helical ribs, projecting radially outwards from an outer surface of the neck 2. The helical thread 6 is intended to cooperate with a complementary helical thread 7, represented on the figures 5 and 6 , formed of a series of helical ribs which are formed in the plug 1 of the plugging device. According to one embodiment, the helical thread 6 formed in the neck 2 as well as the helical thread 7 formed in the cap 1 are interrupted. In other words, the adjacent helical ribs are separated by a space forming a vent and making it possible in particular to evacuate the gas present inside the container while the stopper 1 is still engaged on the neck 2.

Le dispositif de bouchage comporte une bague inférieure 9 qui est retenue sur le col 2 du récipient, un bouchon 1 qui est destiné à recouvrir l'orifice 3 du récipient de manière à l'obturer et un dispositif d'articulation 10 liant le bouchon 1 à la bague inférieure 9. Le bouchon 1 est mobile entre une position de fermeture, représentée sur la figure 1 et une position libérée, représentée sur la figure 3, dans laquelle le bouchon 1 n'est plus en prise avec le col 2. Le bouchon 1 est en outre apte à être basculé de la position libérée vers la position basculée ouverte, représentée sur les figures 4 à 6, dans laquelle le bouchon 1 est dégagé de l'orifice 3 du col 2 de manière qu'il ne gêne pas le déversement du contenu du récipient. Le dispositif de bouchage comporte également un dispositif de blocage agencé pour bloquer le bouchon 1 dans la position basculée ouverte.The closure device comprises a lower ring 9 which is retained on the neck 2 of the container, a stopper 1 which is intended to cover the orifice 3 of the container so as to close it and a hinge device 10 linking the stopper 1 to the lower ring 9. The plug 1 is movable between a closed position, represented on the figure 1 and a released position, shown on the picture 3 , in which the stopper 1 is no longer in engagement with the neck 2. The stopper 1 is further able to be tilted from the released position to the open tilted position, represented on the figures 4 to 6 , wherein the cap 1 is disengaged from the orifice 3 of the neck 2 so that it does not interfere with the discharge of the contents of the container. The stopper device also comprises a locking device arranged to lock the stopper 1 in the open tilted position.

Le bouchon 1 comporte une paroi supérieure 13 destinée à être disposée sensiblement orthogonalement à l'axe X, en regard de l'orifice 3 du col 2 lorsque ledit bouchon 1 est en position de fermeture. Le bouchon 1 comporte, en outre, une jupe périphérique externe 14 destinée à entourer le col 2 du récipient lorsque le bouchon 1 est en position de fermeture. La jupe périphérique externe 14 s'étend, vers le bas, perpendiculairement à la paroi supérieure 13, depuis la périphérie externe de ladite paroi supérieure 13. Le filetage hélicoïdal 7 est ménagé sur la face interne de la jupe périphérique externe 14.The stopper 1 comprises an upper wall 13 intended to be arranged substantially orthogonally to the axis X, facing the orifice 3 of the neck 2 when the said stopper 1 is in the closed position. The cap 1 further comprises an outer peripheral skirt 14 intended to surround the neck 2 of the container when the cap 1 is in the closed position. The outer peripheral skirt 14 extends, downwards, perpendicular to the upper wall 13, from the outer periphery of said upper wall 13. The helical thread 7 is provided on the inner face of the outer peripheral skirt 14.

Comme représenté notamment sur la figure 5, le bouchon 1 comporte une jupe interne 8, qui s'étend perpendiculairement vers le bas depuis la paroi supérieure 13 du bouchon 1 et est dimensionnée de manière à s'insérer à l'intérieur de l'orifice 3 du col 2 ce qui permet d'assurer l'étanchéité de la fermeture.As shown in particular on the figure 5 , the cap 1 comprises an internal skirt 8, which extends perpendicularly downwards from the upper wall 13 of the stopper 1 and is dimensioned so as to be inserted inside the orifice 3 of the neck 2 which makes it possible to ensure the tightness of the closure.

De manière avantageuse, la bague inférieure 9 est, avant la première ouverture du récipient, reliée au bouchon 1 par des ponts frangibles, non illustrés, destinés à se rompre lors de l'ouverture du bouchon 1. Ces ponts frangibles constituent ainsi des témoins d'inviolabilité.Advantageously, the lower ring 9 is, before the first opening of the container, connected to the cap 1 by frangible bridges, not shown, intended to break when the cap 1 is opened. These frangible bridges thus constitute indicators of inviolability.

La bague inférieure 9 est maintenue axialement sur le col 2 du récipient tout en pouvant tourner par rapport à celui-ci autour de l'axe X. Comme représenté sur les figures 1 et 3 à 7, la bague inférieure 9 comporte deux parties qui sont articulées l'une à l'autre, à savoir un premier secteur 16 et un deuxième secteur 17 par lequel la bague inférieure 9 est liée au bouchon 1 au moyen du dispositif d'articulation 10. Ainsi, comme représenté sur la figure 3, le deuxième secteur 17 est apte à pivoter vers le haut par rapport au premier secteur 16, entre une position abaissée dans laquelle au moins la majeure partie du deuxième secteur 17 est destinée à être disposée en-dessous de la collerette d'accrochage 5 et une position relevée, dans laquelle au moins la majeure partie du deuxième secteur 17 est disposée au-dessus de la collerette d'accrochage 5. Ceci autorise le bouchon 1 à se déplacer vers le haut par rapport au col 2 du récipient, jusqu'à ce que le filetage hélicoïdal 7 du bouchon 1 se désengage du filetage hélicoïdal 6 ménagé sur le col 2 du récipient. En d'autres termes, lorsque le bouchon 1 est dévissé, la bague inférieure 9 est entraînée en rotation autour de l'axe X tandis que le deuxième secteur 17 de la bague inférieure 9 pivote par rapport au premier secteur 16 jusqu'à la position relevée de sorte à autoriser un mouvement axial, vers le haut du bouchon 1, de la position de fermeture, jusqu'à la position libérée représentée sur la figure 3. Lorsque le bouchon 1 est pivoté de la position libérée vers la position basculée ouverte, le deuxième secteur 17 de la bague inférieure 9 pivote en sens inverse par rapport au premier secteur 16 et retrouve alors la position abaissée. Par ailleurs, le deuxième secteur 17 pivote également par rapport au premier secteur 16 de la position abaissée vers la position relevée, lorsque le bouchon 1 est pivoté de la position basculée ouverte vers la position libérée.The lower ring 9 is held axially on the neck 2 of the container while being able to rotate relative to the latter around the axis X. As shown in the figure 1 and 3 to 7 , the lower ring 9 comprises two parts which are hinged to one another, namely a first sector 16 and a second sector 17 by which the lower ring 9 is connected to the stopper 1 by means of the hinge device 10. Thus, as shown in the picture 3 , the second sector 17 is capable of pivoting upwards with respect to the first sector 16, between a lowered position in which at least the major part of the second sector 17 is intended to be arranged below the attachment collar 5 and a raised position, in which at least the major part of the second sector 17 is arranged above the attachment flange 5. This allows the stopper 1 to move upwards relative to the neck 2 of the container, until that the helical thread 7 of the cap 1 disengages from the helical thread 6 provided on the neck 2 of the container. In other words, when the cap 1 is unscrewed, the lower ring 9 is rotated around the X axis while the second sector 17 of the lower ring 9 pivots relative to the first sector 16 to the position raised so as to allow an axial movement, upwards of the stopper 1, from the closed position, to the released position represented on the picture 3 . When the cap 1 is pivoted from the released position to the open tilted position, the second sector 17 of the lower ring 9 pivots in the opposite direction with respect to the first sector 16 and then returns to the lowered position. Furthermore, the second sector 17 also pivots relative to the first sector 16 from the lowered position to the raised position, when the cap 1 is pivoted from the open tilted position to the released position.

La bague inférieure 9 est maintenue axialement sur le col 2 du récipient au moyen de la collerette d'accrochage 5. Comme représenté sur la figure 2, la collerette d'accrochage 5 présente une surface externe tronconique se rétrécissant vers le haut, c'est-à-dire en direction de l'orifice 3 du récipient. La collerette d'accrochage 5 délimite, vers le bas, c'est-à-dire dans une direction opposée à l'orifice 3, un épaulement.The lower ring 9 is held axially on the neck 2 of the container by means of the attachment flange 5. As shown in the figure 2 , the attachment flange 5 has a frustoconical outer surface tapering upwards, that is to say in the direction of the orifice 3 of the container. The attachment collar 5 delimits, downwards, that is to say in a direction opposite to the orifice 3, a shoulder.

Comme représenté sur la figure 6, le premier secteur 16 de la bague inférieure 9 comporte des éléments d'accrochage 18 qui sont destinés à coopérer avec la collerette d'accrochage 5 ménagée sur le récipient afin de retenir axialement la bague inférieure 9 au col 2 du récipient. Les éléments d'accrochage 18 sont des protubérances qui font saillie radialement vers l'intérieur depuis le premier secteur 16 de la bague inférieure 9. De manière avantageuse, les éléments d'accrochage 18 présentent une dimension radiale qui augmente, du bas vers le haut, c'est-à-dire en direction du bord supérieur de la bague inférieure 9. Lors de l'assemblage du dispositif de bouchage sur le col 2 du récipient, les éléments d'accrochage 18 glissent contre la surface tronconique de la collerette d'accrochage 5 puis se verrouillent par rappel élastique derrière la collerette d'accrochage 5.As shown on the figure 6 , the first sector 16 of the lower ring 9 comprises hooking elements 18 which are intended to cooperate with the hooking collar 5 provided on the container in order to retain the lower ring 9 axially at the neck 2 of the container. The hooking elements 18 are protuberances which protrude radially inwards from the first sector 16 of the lower ring 9. Advantageously, the hooking elements 18 have a radial dimension which increases, from bottom to top. , that is to say in the direction of the upper edge of the lower ring 9. When assembling the closure device on the neck 2 of the container, the attachment elements 18 slide against the frustoconical surface of the collar d attachment 5 then lock by elastic return behind the attachment flange 5.

Le premier secteur 16 de la bague inférieure 9 comporte une zone avant 19 qui est diamétralement opposée au deuxième secteur 17 de la bague inférieure 9 et deux zones d'accrochage 20, 21 représentées sur les figures 6 et 7, qui sont disposées de part et d'autre de la zone avant 19 et sont chacune disposées entre la zone avant 19 et le deuxième secteur 17 de la bague inférieure 9. Les éléments d'accrochage 18 sont exclusivement disposés dans les deux zones d'accrochage 20, 21. Ainsi, en raison de l'absence d'éléments d'accrochage 18 dans la zone avant 19 du premier secteur 16, il existe un jeu radial entre la bague inférieure 9 et le col 2, ce qui permet à la bague inférieure 9 de se déplacer de l'avant vers l'arrière et inversement. Ceci permet de faciliter le passage d'une partie du deuxième secteur 17 de part et d'autre de la collerette d'accrochage 5 lors du mouvement du deuxième secteur 17 entre la position abaissée et la position relevée. En d'autres termes, les efforts de traction à exercer sur la bague inférieure 9 pour permettre au deuxième secteur 17 de passer de part et d'autre de la collerette d'accrochage 5 sont moindres.The first sector 16 of the lower ring 9 comprises a front zone 19 which is diametrically opposed to the second sector 17 of the lower ring 9 and two attachment zones 20, 21 represented on the figure 6 and 7 , which are arranged on either side of the front zone 19 and are each arranged between the front zone 19 and the second sector 17 of the lower ring 9. The attachment elements 18 are exclusively arranged in the two zones of attachment 20, 21. Thus, due to the absence of attachment elements 18 in the front zone 19 of the first sector 16, there is radial clearance between the lower ring 9 and the neck 2, which allows the lower ring 9 to move from front to rear and vice versa. This facilitates the passage of a part of the second sector 17 on either side of the attachment collar 5 during the movement of the second sector 17 between the lowered position and the raised position. In other words, the tensile forces to be exerted on the lower ring 9 to allow the second sector 17 to pass on either side of the attachment collar 5 are lower.

De manière avantageuse, le deuxième secteur 17 s'étend sur une plage angulaire comprise entre 90 et 150°, la zone avant 19 du premier secteur 16 s'étend sur une plage angulaire comprise entre 60 et 150 tandis que chacune des deux zones d'accrochage 20, 21 s'étend sur une plage angulaire comprise entre 30 et 90°.Advantageously, the second sector 17 extends over an angular range comprised between 90 and 150°, the front zone 19 of the first sector 16 extends over an angular range comprised between 60 and 150 while each of the two zones of attachment 20, 21 extends over an angular range between 30 and 90°.

Le dispositif d'articulation 10 comporte deux lamelles 11, 12, notamment visibles sur les figures 1 et 4, qui relient le bouchon 1 et plus particulièrement la jupe périphérique externe 14 du bouchon 1 à la bague inférieure 9, et plus particulièrement au deuxième secteur 17 de la bague inférieure 9.The articulation device 10 comprises two slats 11, 12, in particular visible on the figure 1 and 4 , which connect the cap 1 and more particularly the outer peripheral skirt 14 of the cap 1 to the lower ring 9, and more particularly to the second sector 17 of the lower ring 9.

Les lamelles 11, 12 rejoignent la jupe périphérique externe 14 dans une portion échancrée. De même, les lamelles 11, 12 rejoignent le deuxième secteur 17 de la bague inférieure 2 dans une portion échancrée. En d'autres termes, les lamelles 11, 12 s'étendent sensiblement au-dessus de la limite inférieure de la jupe périphérique externe 9 et s'étendent sensiblement en dessous de la limite supérieure de la bague inférieure 3.The slats 11, 12 join the outer peripheral skirt 14 in a notched portion. Similarly, the slats 11, 12 join the second sector 17 of the lower ring 2 in a notched portion. In other words, the slats 11, 12 extend substantially above the lower limit of the outer peripheral skirt 9 and extend substantially below the upper limit of the lower ring 3.

Le dispositif de blocage comporte un taquet 23 qui fait saillie radialement vers l'extérieur depuis la jupe périphérique externe 14 du bouchon 1. Le taquet 23 s'étend circonférentiellement entre les deux lamelles 11, 12. Le dispositif de blocage comporte également une portion en saillie 24 qui fait saillie axialement vers le haut, c'est-à-dire vers la jupe périphérique externe 14 du bouchon 1, depuis une portion centrale 25 du deuxième secteur 17 de la bague inférieure 9. La portion en saillie 24 fait également saillie entre les deux lamelles 11, 12.The blocking device comprises a tab 23 which projects radially outwards from the outer peripheral skirt 14 of the stopper 1. The tab 23 extends circumferentially between the two blades 11, 12. The blocking device also comprises a portion in projection 24 which projects axially upwards, that is to say towards the outer peripheral skirt 14 of the stopper 1, from a central portion 25 of the second sector 17 of the lower ring 9. The projecting portion 24 also projects between the two slats 11, 12.

Par ailleurs, le bouchon 1 comporte un talon 22, notamment visible sur la figure 1, qui est ménagé dans la jupe périphérique externe 14 du bouchon 1. Le talon 22 fait saillie axialement vers le bas, c'est-à-dire en direction de la bague inférieure 9, depuis la jupe périphérique externe 14 du bouchon 1. Le talon 22 fait saillie entre les deux lamelles 11, 12. Le talon 22 permet ainsi de limiter les dimensions des espaces et interstices ménagées entre les lamelles 11, 12 et susceptibles d'accueillir des corps extérieurs. A titre d'exemple, la hauteur de l'interstice ménagé axialement entre le talon 22 et la portion en saillie 24 est inférieure à 0.6 mm et de préférence comprise entre 0.3 et 0.6 mm.Furthermore, the stopper 1 comprises a heel 22, in particular visible on the figure 1 , which is formed in the outer peripheral skirt 14 of the cap 1. The heel 22 projects axially downwards, that is to say in the direction of the lower ring 9, from the outer peripheral skirt 14 of the cap 1. The heel 22 protrudes between the two slats 11, 12. The heel 22 thus makes it possible to limit the dimensions of the spaces and interstices made between the slats 11, 12 and capable of accommodating external bodies. By way of example, the height of the gap provided axially between the heel 22 and the projecting portion 24 is less than 0.6 mm and preferably between 0.3 and 0.6 mm.

Comme représenté sur les figures 4 et 5, le taquet 23 et la portion en saillie 24 sont agencés de telle sorte que, lorsque le bouchon 1 est en position basculée ouverte, le taquet 23 vient en appui contre la portion en saillie 24. Les lamelles 11, 12 ainsi que le taquet 23 et la portion en saillie 24 sont configurés de telle sorte que, durant une première partie du mouvement du bouchon 4 de la position libérée vers la position basculée ouverte, les deux lamelles élastiques 11, 12 sont, en raison de l'appui du taquet 23 contre la portion en saillie 24, soumis à une force de traction qui augmente jusqu'à une position instable intermédiaire puis qui décroit de ladite position instable intermédiaire vers la position basculée ouverte. Ceci permet de bloquer le bouchon 1 dans la position basculée ouverte.As shown on the figure 4 and 5 , the cleat 23 and the projecting portion 24 are arranged such that, when the plug 1 is in the open tilted position, the cleat 23 bears against the projecting portion 24. The slats 11, 12 as well as the cleat 23 and the projecting portion 24 are configured such that, during a first part of the movement of the stopper 4 from the released position to the open tilted position, the two elastic strips 11, 12 are, due to the support of the cleat 23 against the projecting portion 24, subjected to a tensile force which increases to an intermediate unstable position and then decreases from said intermediate unstable position towards the open tilted position. This makes it possible to block the cap 1 in the open tilted position.

Comme représenté sur les figures 6 et 7, l'épaisseur de la bague inférieure 9 est augmentée localement au moins au niveau de la portion en saillie 24. Ainsi, la portion en saillie 24 présente une épaisseur radiale ε1 qui est supérieure à une épaisseur radiale ε2 du premier secteur 16 de la bague inférieure 9 hors des zones d'accrochage 20, 21. Cette augmentation de l'épaisseur de la bague inférieure 9 permet de diminuer d'autant la dimension radiale du taquet 23.As shown on the figure 6 and 7 , the thickness of the lower ring 9 is increased locally at least at the level of the projecting portion 24. Thus, the projecting portion 24 has a radial thickness ε1 which is greater than a radial thickness ε2 of the first sector 16 of the ring lower ring 9 outside the attachment zones 20, 21. This increase in the thickness of the lower ring 9 makes it possible to reduce the radial dimension of the cleat 23 by the same amount.

Par ailleurs, la face interne et la face externe 27 de la portion en saillie 24 s'étendent parallèlement à l'axe X et sont alignées selon la direction axiale avec la face interne et la face externe 26 de la portion centrale 25 du deuxième secteur 17 de la bague inférieure 9. Ceci assure une continuité des faces interne et externe de la portion en saillie 24 avec celle de la bague inférieure 9, sans surface anguleuse.Furthermore, the internal face and the external face 27 of the projecting portion 24 extend parallel to the axis X and are aligned in the axial direction with the internal face and the external face 26 of the central portion 25 of the second sector 17 of the lower ring 9. This ensures continuity of the inner and outer faces of the projecting portion 24 with that of the lower ring 9, without any angular surface.

Par ailleurs, en relation avec la figure 7, on observe que la face externe du deuxième secteur 17 de la bague inférieure 9 s'éloigne progressivement de l'axe X depuis chacune des extrémités du deuxième secteur jusqu'à la portion centrale 25 du deuxième secteur 17 tandis que la face interne du deuxième secteur 17 est inscrite sur un cercle concentrique à l'axe X. Ceci permet d'augmenter l'épaisseur de la bague inférieure 9, au niveau de la portion arrière 25, par une augmentation progressive de l'épaisseur du deuxième secteur 17, ce qui permet d'éviter la présence de surfaces anguleuses.Moreover, in relation to the figure 7 , it is observed that the outer face of the second sector 17 of the lower ring 9 gradually moves away from the axis X from each of the ends of the second sector to the central portion 25 of the second sector 17 while the inner face of the second sector 17 is inscribed on a circle concentric with the axis X. This makes it possible to increase the thickness of the lower ring 9, at the level of the rear portion 25, by a progressive increase in the thickness of the second sector 17, which avoids the presence of angular surfaces.

Par ailleurs, de manière avantageuse, comme représenté sur la figure 7, la face externe 26 de la portion centrale 25 du deuxième secteur 17 ainsi que la face externe 27 de la portion en saillie 24 s'étendent selon un plan perpendiculaire à un plan de symétrie radial du dispositif de bouchage. De plus, l'extrémité 28 du taquet 23 est plane et parallèle aux faces externes 26, 27 de la portion centrale 25 du deuxième secteur 17 et de la portion en saillie 24.Furthermore, advantageously, as shown in the figure 7 , the outer face 26 of the central portion 25 of the second sector 17 and the outer face 27 of the projecting portion 24 extend along a plane perpendicular to a radial plane of symmetry of the closure device. In addition, the end 28 of the cleat 23 is flat and parallel to the outer faces 26, 27 of the central portion 25 of the second sector 17 and of the projecting portion 24.

A titre d'exemple, l'épaisseur radiale ε1 de la portion en saillie est comprise entre 0.4 et 2 mm et de préférence comprise entre 1 et 2 mm.By way of example, the radial thickness ε1 of the projecting portion is between 0.4 and 2 mm and preferably between 1 and 2 mm.

De manière avantageuse, comme illustré par exemple sur la figure 1 et 6, la portion en saillie 24 présente des évidements 29. Les évidements 29 débouchent au niveau de l'extrémité libre de la portion en saillie 24 ainsi que sur la face externe 27 de la portion en saillie 24. De tels évidements 29 sont avantageux en ce qu'ils facilitent l'obtention par un procédé de moulage d'un dispositif de bouchage ayant une telle augmentation locale d'épaisseur de la bague inférieure 9 au niveau de la portion en saillie 24. En effet, pour mouler un tel dispositif de bouchage, le moule est équipé d'une lame d'acier qui est destinée à ménager l'interstice entre le talon 22 et la portion en saillie 24 afin de les séparer. L'augmentation de l'épaisseur radiale ε1 de la portion en saillie 24 conduit à une augmentation des contraintes s'exerçant sur la lame d'acier lors du moulage, ce qui la fragilise. Or, augmenter l'épaisseur de cette lame d'acier afin de la renforcer est proscrit car cela conduirait à augmenter la hauteur de l'interstice ménagé entre le talon 23 et la portion en saillie 24 et par conséquent à permettre à des corps extérieurs indésirables de s'y loger. Ainsi, afin de renforcer ladite lame d'acier, celle-ci comporte des nervures de renforcement, dont la forme correspond à celle des évidements 29 formés dans la portion en saillie 24.Advantageously, as illustrated for example in the figure 1 and 6 , the projecting portion 24 has recesses 29. The recesses 29 open at the free end of the projecting portion 24 as well as on the outer face 27 of the projecting portion 24. Such recesses 29 are advantageous in that that they facilitate obtaining by a molding process a closure device having such a local increase in thickness of the lower ring 9 at the level of the projecting portion 24. Indeed, to mold such a closure device , the mold is equipped with a steel blade which is intended to provide the gap between the heel 22 and the projecting portion 24 in order to separate them. The increase in the radial thickness ε1 of the projecting portion 24 leads to an increase in the stresses exerted on the steel strip during molding, which weakens it. However, increasing the thickness of this steel blade in order to reinforce it is prohibited because this would lead to increasing the height of the gap provided between the heel 23 and the projecting portion 24 and consequently to allow undesirable external bodies to stay there. Thus, in order to reinforce said steel blade, the latter comprises reinforcing ribs, the shape of which corresponds to that of the recesses 29 formed in the projecting portion 24.

Par ailleurs, comme représenté sur la figure 1, le taquet 23 présente une surface supérieure 30 en biseau. En d'autres termes, la hauteur du taquet 23 diminue depuis la jupe périphérique externe 14 vers l'extrémité 28 du taquet 23. En outre, l'extrémité 28 du taquet 23 présente une hauteur inférieure à 1 mm, de préférence inférieure à 0.8 mm, par exemple de l'ordre de 0.6 mm. Ainsi, lors du mouvement du bouchon vers la position basculée ouverte, le bouchon 1 bascule autour du point de contact entre l'extrémité 28 du taquet 23 et la portion en saillie 24 jusqu'à ce que la surface supérieure 30 vienne en appui contre la portion en saillie 24. La forme biseautée de la surface supérieure 30 du taquet 23 permet ainsi d'augmenter l'angle d'ouverture du bouchon 1 en position basculée ouverte. Ainsi, l'angle d'ouverture qui correspond au secteur angulaire saillant qui est formé à l'intersection entre un plan parallèle à la paroi supérieure 13 du bouchon 1 et un plan horizontal est supérieur à 180°, avantageusement supérieure à 190 ° et par exemple de l'ordre de 200°.Furthermore, as shown in the figure 1 , the cleat 23 has an upper surface 30 bevelled. In other words, the height of the cleat 23 decreases from the outer peripheral skirt 14 towards the end 28 of the cleat 23. In addition, the end 28 of the cleat 23 has a height of less than 1 mm, preferably less than 0.8 mm, for example of the order of 0.6 mm. Thus, during the movement of the stopper towards the open tilted position, the stopper 1 tilts around the point of contact between the end 28 of the tab 23 and the projecting portion 24 until the surface upper 30 bears against the projecting portion 24. The bevelled shape of the upper surface 30 of the cleat 23 thus makes it possible to increase the opening angle of the plug 1 in the open tilted position. Thus, the opening angle which corresponds to the salient angular sector which is formed at the intersection between a plane parallel to the upper wall 13 of the stopper 1 and a horizontal plane is greater than 180°, advantageously greater than 190° and by example of the order of 200°.

De manière avantageuse, lorsque le bouchon 1 est dans la position basculée ouverte, la portion en saillie 24 est prise en sandwich entre le taquet 23 et la collerette d'accrochage 5. En d'autres termes, lorsque le bouchon 1 est en position basculée ouverte, le taquet 23 et la portion en saillie 24 sont en contact l'un contre l'autre dans une zone située dans le plan de la collerette d'accrochage 5 et la portion en saillie 24 est également en contact contre la collerette d'accrochage 5. Ceci permet de garantir un blocage robuste du bouchon en position basculée ouverte.Advantageously, when the cap 1 is in the open tilted position, the projecting portion 24 is sandwiched between the tab 23 and the attachment collar 5. In other words, when the cap 1 is in the tilted position open, the catch 23 and the protruding portion 24 are in contact against each other in a zone located in the plane of the attachment collar 5 and the protruding portion 24 is also in contact against the collar of hooking 5. This makes it possible to guarantee a robust blocking of the cap in the tilted open position.

La cinématique du bouchon 1 est la suivante. Lors du premier dévissage, le bouchon 1 quitte la position de fermeture et s'éloigne de la bague inférieure 9 jusqu'à la position libérée, illustrée sur la figure 3. Les ponts frangibles se rompent au cours de ce mouvement. En outre, lors de ce mouvement de dévissage du bouchon 1, la bague inférieure 9 est entraînée en rotation autour de l'axe X et le deuxième secteur 17 de la bague inférieure 9 pivote vers la position relevée au furet à mesure que le bouchon 1 s'éloigne de la collerette d'accrochage 5.The kinematics of stopper 1 is as follows. During the first unscrewing, the cap 1 leaves the closed position and moves away from the lower ring 9 to the released position, illustrated in the picture 3 . The frangible bridges break during this movement. In addition, during this movement of unscrewing the cap 1, the lower ring 9 is driven in rotation around the axis X and the second sector 17 of the lower ring 9 pivots towards the raised position as the cap 1 moves away from the attachment collar 5.

Par la suite, le bouchon 1 peut alors être pivoté vers l'arrière en direction de la position basculée ouverte dans laquelle la jupe périphérique externe 14 s'étend vers le haut depuis la paroi supérieure 13. Lors du mouvement du bouchon 1 vers l'arrière en direction de sa position basculée ouverte, le taquet 23 vient en appui contre la portion en saillie 24 et entraîne ainsi le pivotement du deuxième secteur 17 de la bague inférieure 9 de la position relevée vers la position abaissée.Subsequently, the cap 1 can then be pivoted rearward towards the open tilted position in which the outer peripheral skirt 14 extends upwards from the upper wall 13. During the movement of the cap 1 towards the rear towards its open tilted position, the cleat 23 bears against the projecting portion 24 and thus causes the pivoting of the second sector 17 of the lower ring 9 from the raised position to the lowered position.

Les possibilités d'étirement des lamelles 11, 10 conjointement aux caractéristiques précitées du dispositif de blocage, permettent de créer un point dur lors du basculement du bouchon 1 entre la position libérée, représentée sur la figure 3, et la position basculée ouverte, représentée sur les figures 4 et 5.The possibilities of stretching of the slats 11, 10 together with the aforementioned characteristics of the locking device, make it possible to create a hard point when the stopper 1 tilts between the released position, represented on the picture 3 , and the open tilted position, represented on the figure 4 and 5 .

Comme représenté sur les figures 5 et 6, lorsque le deuxième secteur 17 de la bague inférieure 9 est dans la position abaissée et que le bouchon 1 est dans sa position basculée ouverte, le taquet 23 est en appui contre la portion en saillie 24 qui se trouve ainsi prise en sandwich entre ledit taquet 23 et la collerette d'accrochage 5.As shown on the figures 5 and 6 , when the second sector 17 of the lower ring 9 is in the lowered position and the plug 1 is in its open tilted position, the tab 23 bears against the projecting portion 24 which is thus sandwiched between said tab 23 and the attachment collar 5.

Ainsi, le bouchon 1 demeure dans sa position basculée ouverte puisque, en raison de la disposition précitée, le bouchon 1 ne peut pas être pivoté vers la position libérée dans laquelle le bouchon 1 est en regard de l'orifice 3 de distribution tant que le deuxième secteur 17 de la bague inférieure 9 reste dans la position abaissée.
Pour refermer le bouchon 1, l'utilisateur bascule le bouchon 1 vers l'avant jusqu'à la position libérée. Lors de ce basculement, le contact entre le taquet 23 et la portion en saillie 24 disparait, ce qui autorise le mouvement du deuxième secteur 17 de la bague inférieure 9 vers la position relevée.Thus, the cap 1 remains in its open tilted position since, due to the aforementioned arrangement, the cap 1 cannot be pivoted towards the released position in which the cap 1 is facing the dispensing orifice 3 as long as the second sector 17 of the lower ring 9 remains in the lowered position.
To close cap 1, the user tilts cap 1 forward to the released position. During this tilting, the contact between the cleat 23 and the projecting portion 24 disappears, which allows the movement of the second sector 17 of the lower ring 9 towards the raised position.

Lorsque le deuxième secteur 17 est dans la position relevée et que le bouchon 1 est dans la position libérée, ledit bouchon 1 peut alors être revissé sur le col 2 du récipient. Lors du revissage, la bague inférieure 9 est entraînée en rotation autour de l'axe X et le deuxième secteur 17 de la bague inférieure 9 pivote vers la position abaissée au fur et à mesure que le bouchon 1 s'approche de la collerette d'accrochage 5.When the second sector 17 is in the raised position and the stopper 1 is in the released position, said stopper 1 can then be screwed back onto the neck 2 of the container. During screwing, the lower ring 9 is driven in rotation around the X axis and the second sector 17 of the lower ring 9 pivots towards the lowered position as the cap 1 approaches the collar of hooking 5.

De manière avantageuse, l'ensemble du dispositif de bouchage est venu de moulage en une seule pièce de matière synthétique, tel que du polyéthylène et avantageusement du polyéthylène haute densité. De manière avantageuse, le dispositif de bouchage est moulé dans la configuration de la figure 1, c'est-à-dire dans une position de fermeture, position dans laquelle il peut être directement monté sur le col 2 du récipient.Advantageously, the entire closure device is molded in a single piece of synthetic material, such as polyethylene and advantageously high density polyethylene. Advantageously, the closure device is molded in the configuration of the figure 1 , that is to say in a closed position, a position in which it can be mounted directly on the neck 2 of the container.

Bien que l'invention ait été décrite en liaison avec plusieurs modes de réalisation particuliers, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.Although the invention has been described in connection with several particular embodiments, it is obvious that it is in no way limited thereto and that it includes all the technical equivalents of the means described as well as their combinations if these fall within the scope of the invention.

L'usage du verbe « comporter », « comprendre » ou « inclure » et de ses formes conjuguées n'exclut pas la présence d'autres éléments ou d'autres étapes que ceux énoncés dans une revendication.The use of the verb "to comprise", "to understand" or "to include" and of its conjugated forms does not exclude the presence of other elements or other steps than those set out in a claim.

Dans les revendications, tout signe de référence entre parenthèses ne saurait être interprété comme une limitation de la revendication.In the claims, any reference sign in parentheses cannot be interpreted as a limitation of the claim.
