L'invention concerne notamment les dispositifs de bouchage dans lesquels la base est une bague inférieure qui est destinée à être retenue sur le col du récipient ainsi que ceux dans lesquels la base comporte un élément verseur qui est destiné à être fixé au col d'un récipient.The invention relates in particular to closure devices in which the base is a lower ring which is intended to be retained on the neck of the container as well as those in which the base comprises a pouring element which is intended to be fixed to the neck of a container.

Arrière-plan technologiqueTechnology background

Dans l'état de la technique, il est connu des dispositifs de bouchage comportant une base destinée à être fixée à un col d'un récipient et un bouchon articulé à ladite base par un dispositif d'articulation. Le bouchon comporte une paroi supérieure et une jupe périphérique externe qui s'étend vers le bas, depuis la périphérie externe de la paroi supérieure.In the state of the art, stopper devices are known comprising a base intended to be fixed to a neck of a container and a stopper hinged to said base by a hinge device. The cap has a top wall and an outer peripheral skirt that extends downward from the outer periphery of the top wall.

Le dispositif d'articulation autorise le mouvement du bouchon entre une position de fermeture dans laquelle la paroi supérieure du bouchon obture un orifice du récipient ou de l'élément verseur et une position basculée ouverte dans laquelle le bouchon est dégagé dudit orifice. Le dispositif d'articulation comporte une ou plusieurs lamelles formant charnière qui relient le bouchon à la base. Afin de permettre aux lamelles d'avoir une longueur suffisante pour autoriser le mouvement du bouchon entre la position de fermeture et la position basculée ouverte, la jupe périphérique externe du bouchon comporte des portions échancrées et les lamelles rejoignent chacune la jupe périphérique du bouchon au niveau du bord supérieur de l'une desdites portions échancrées de sorte que les lamelles s'étendent au-dessus du bord inférieur de la jupe périphérique externe du bouchon.The hinge device allows movement of the stopper between a closed position in which the upper wall of the stopper closes off an orifice of the container or of the pouring element and a tilted open position in which the stopper is disengaged from said orifice. The articulation device comprises one or more blades forming a hinge which connect the stopper to the base. In order to allow the slats to have a sufficient length to allow movement of the stopper between the closed position and the open tilted position, the outer peripheral skirt of the stopper has indented portions and the slats each join the peripheral skirt of the stopper at the level from the upper edge of one of said indented portions so that the slats extend above the lower edge of the outer peripheral skirt of the cap.

De tels dispositifs de bouchage sont, par exemple, décrits dans les documents EP1406820 , US2018086510 , WO20193821 ou EP3722223 . Le document TW 201144172 divulgue un dispositif de bouchage selon le préambule de la revendication 1 et décrit un couvercle pour empêcher sa perte et sa rotation, en empêchant l'oscillation de son corps de couvercle lorsque le couvercle est ouvert au moyen d'un sous-connecteur formé de part et d'autre d'un connecteur principal, un corps de récipient pourvu d'une partie filetée sur le col de celui-ci ; un anneau de fixation pour empêcher le désengagement du corps du récipient ; un corps de couvercle définissant une partie filetée sur une périphérie interne de celui-ci pour correspondre à la partie filetée du corps de récipient; et un couvercle pourvu d'une partie charnière reliant l'anneau de fixation au corps de couvercle.Such plugging devices are, for example, described in the documents EP1406820 , US2018086510 , WO20193821 Or EP3722223 . The document TW 201144172 discloses a capping device according to the preamble of claim 1 and describes a cover to prevent its loss and rotation, by preventing the oscillation of its cover body when the cover is opened by means of a sub-connector formed by and on the other a main connector, a receptacle body provided with a threaded part on the neck thereof; a securing ring to prevent disengagement from the body of the container; a lid body defining a threaded portion on an inner periphery thereof to match the threaded portion of the container body; and a cover provided with a hinge part connecting the fixing ring to the cover body.

De tels dispositifs de bouchage sont typiquement réalisés en matériau polymère par des procédés de moulage. Dans chaque portion destinée à la réalisation d'une portion échancrée recevant une lamelle, la moule comporte deux lames venant de part et d'autre de chaque lamelle à mouler, entre ladite lamelle et la jupe périphérique externe. Les lames présentent généralement une épaisseur relativement importante, typiquement de l'ordre de 0.3 mm à 1,5 mm, de manière à leur conférer une résistance suffisante.Such plugging devices are typically made of polymer material by molding processes. In each portion intended for the production of a notched portion receiving a lamella, the mold comprises two blades coming from either side of each lamella to be molded, between said lamella and the outer peripheral skirt. The blades generally have a relatively large thickness, typically of the order of 0.3 mm to 1.5 mm, so as to give them sufficient strength.

Ainsi, les portions échancrées forment de part et d'autre de chaque lamelle des interstices ayant une largeur importante, typiquement supérieure à 0.5 mm. Or, ces interstices sont susceptibles d'héberger des particules, poussières ou organismes indésirables. De tels dispositifs de bouchage ne sont donc pas pleinement satisfaisants.Thus, the indented portions form on either side of each strip interstices having a large width, typically greater than 0.5 mm. However, these interstices are likely to harbor undesirable particles, dust or organisms. Such plugging devices are therefore not entirely satisfactory.

RésuméSummary

Une idée à la base de l'invention est de proposer un dispositif de bouchage du type précité dans lequel l'hygiène et la sécurité sont améliorées.One idea underlying the invention is to provide a closure device of the aforementioned type in which hygiene and safety are improved.

Selon un mode de réalisation, l'invention fournit un dispositif de bouchage comportant :

  • une base destinée à être fixée à un récipient ;
  • un bouchon comportant une paroi supérieure et une jupe périphérique externe, le bouchon étant apte et destiné à être disposé dans une position de fermeture dans laquelle la paroi supérieure obture un orifice ; et
  • un dispositif d'articulation qui relie le bouchon à la base, le dispositif d'articulation comportant au moins une première lamelle reliant la jupe périphérique externe du bouchon à la base, la jupe périphérique externe présentant une première portion échancrée comportant un bord supérieur s'étendant au-dessus d'un bord inférieur de ladite jupe périphérique externe et un premier bord latéral reliant le bord supérieur de la première portion échancrée au bord inférieur de la jupe périphérique externe, ladite première lamelle étant liée au bord supérieur de la première portion échancrée, le bouchon comportant, en outre, au moins un premier voile anti-intrusion ayant une épaisseur inférieure à celle de la jupe périphérique externe, ledit voile anti-intrusion s'étendant depuis le bord supérieur de la portion première échancrée et depuis le premier bord latéral de la première portion échancrée, à l'intérieur de la première portion échancrée.
According to one embodiment, the invention provides a closure device comprising:
  • a base intended to be attached to a container;
  • a cap comprising an upper wall and an outer peripheral skirt, the cap being able and intended to be arranged in a closed position in which the upper wall closes off an orifice; And
  • a hinge device which connects the cap to the base, the hinge device comprising at least a first blade connecting the outer peripheral skirt of the cap to the base, the outer peripheral skirt having a first portion indented comprising an upper edge extending above a lower edge of said outer peripheral skirt and a first lateral edge connecting the upper edge of the first indented portion to the lower edge of the outer peripheral skirt, said first slat being linked to the upper edge of the first indented portion, the cap further comprising at least one first anti-intrusion veil having a thickness less than that of the outer peripheral skirt, said anti-intrusion veil extending from the upper edge of the portion first indented portion and from the first side edge of the first indented portion, inside the first indented portion.

Ainsi, le voile anti-intrusion permettant d'empêcher les corps extérieurs de venir se loger dans au moins une zone de la portion échancrée, l'hygiène et la sécurité du dispositif de bouchage sont améliorées.Thus, the anti-intrusion web making it possible to prevent external bodies from becoming lodged in at least one zone of the indented portion, the hygiene and safety of the closure device are improved.

En outre, le voile anti-intrusion présentant une épaisseur inférieure à celle de la jupe périphérique externe, les caractéristiques fonctionnelles de l'articulation sont peu ou pas dégradées.In addition, the anti-intrusion web having a thickness less than that of the outer peripheral skirt, the functional characteristics of the joint are little or not degraded.

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, le premier voile anti-intrusion présente une épaisseur comprise entre 0,05 et 0,5 mm.According to one embodiment, the first anti-intrusion veil has a thickness of between 0.05 and 0.5 mm.

Selon un mode de réalisation, le premier voile anti-intrusion comporte un bord libre inférieur qui s'étend dans le prolongement du bord inférieur de la jupe périphérique externe.According to one embodiment, the first anti-intrusion veil comprises a lower free edge which extends in the extension of the lower edge of the outer peripheral skirt.

Selon un mode de réalisation, le premier voile anti-intrusion comporte un bord libre latéral qui s'étend parallèlement à un bord latéral de la première lamelle.According to one embodiment, the first anti-intrusion veil comprises a lateral free edge which extends parallel to a lateral edge of the first slat.

Selon un mode de réalisation, le bord libre latéral du premier voile anti-intrusion est écarté d'un bord latéral adjacent de la première lamelle d'un interstice présentant une largeur comprise entre 0,01 et 0,4 mm. Ainsi, l'interstice présente une largeur suffisamment faible pour empêcher la majeure partie des corps extérieurs de venir s'y loger tout en étant suffisamment important pour ne pas risquer de perturber les fonctionnalités des lamelles et pour être compatible avec les contraintes du procédé de moulage.According to one embodiment, the free lateral edge of the first anti-intrusion veil is separated from an adjacent lateral edge of the first slat by a gap having a width of between 0.01 and 0.4 mm. Thus, the interstice presents a width sufficiently small to prevent the major part of the external bodies from coming to lodge there while being sufficiently large not to risk disturbing the functionalities of the slats and to be compatible with the constraints of the molding process.

Selon un autre mode de réalisation, le premier voile anti-intrusion s'étend en outre depuis un bord latéral de la première lamelle. Il n'y a donc pas d'interstice entre le premier voile anti-intrusion et la lamelle adjacente.According to another embodiment, the first anti-intrusion veil also extends from a side edge of the first slat. There is therefore no gap between the first anti-intrusion veil and the adjacent slat.

Selon un mode de réalisation, la première portion échancrée comporte un deuxième bord latéral reliant le bord supérieur de la première portion échancrée au bord inférieur de la jupe périphérique externe, le premier bord latéral et le deuxième bord latéral de la première portion échancrée étant disposés de part et d'autre de la première lamelle, le bouchon comportant en outre un deuxième voile anti-intrusion présentant une épaisseur inférieure à celle de la jupe périphérique externe, ledit deuxième voile anti-intrusion s'étendant depuis le bord supérieur de la première portion échancrée et depuis le deuxième bord latéral de la première portion échancrée, à l'intérieur de la première portion échancrée.According to one embodiment, the first scalloped portion comprises a second lateral edge connecting the upper edge of the first scalloped portion to the lower edge of the outer peripheral skirt, the first lateral edge and the second lateral edge of the first scalloped portion being arranged on either side of the first lamella, the cap further comprising a second anti-intrusion web having a thickness less than that of the outer peripheral skirt, said second anti-intrusion web extending from the upper edge of the first portion indented and from the second side edge of the first indented portion, inside the first indented portion.

Selon un mode de réalisation, le dispositif d'articulation comporte une deuxième lamelle reliant la jupe périphérique externe du bouchon à la base, la jupe périphérique externe présentant une deuxième portion échancrée comportant un bord supérieur s'étendant au-dessus du bord inférieur de la jupe périphérique externe et un premier bord latéral reliant le bord supérieur de la deuxième portion échancrée au bord inférieur de la jupe périphérique externe, ladite deuxième lamelle étant liée au bord supérieur de la deuxième portion échancrée, le bouchon comportant, en outre, pour chacune des première et deuxième portions échancrées au moins un premier voile anti-intrusion ayant une épaisseur inférieure à celle de la jupe périphérique externe et s'étendant depuis le bord supérieur et le premier bord latéral de la première ou deuxième portion échancrée, à l'intérieur de ladite première ou deuxième portion échancrée.According to one embodiment, the hinge device comprises a second lamella connecting the outer peripheral skirt of the plug to the base, the outer peripheral skirt having a second indented portion comprising an upper edge extending above the lower edge of the outer peripheral skirt and a first lateral edge connecting the upper edge of the second indented portion to the lower edge of the outer peripheral skirt, said second strip being linked to the upper edge of the second indented portion, the cap further comprising, for each of the first and second indented portions at least a first anti-intrusion veil having a thickness less than that of the outer peripheral skirt and extending from the upper edge and the first lateral edge of the first or second indented portion, inside said first or second indented portion.

Selon un mode de réalisation, la base comporte une bague inférieure qui est destinée à être retenue au col du récipient.According to one embodiment, the base comprises a lower ring which is intended to be retained at the neck of the container.

Selon un mode de réalisation, la base comporte un élément verseur qui est destiné à être solidarisé au col du récipient.According to one embodiment, the base comprises a pouring element which is intended to be secured to the neck of the container.

Selon un mode de réalisation, le dispositif de bouchage est réalisé en matériau polymère par un procédé de moulage.According to one embodiment, the closure device is made of polymer material by a molding process.

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, l'invention fournit également un récipient équipé d'un col comportant un orifice et un dispositif de bouchage précité, la base dudit dispositif de bouchage étant fixée au récipient.According to one embodiment, the invention also provides a container equipped with a neck comprising an orifice and an aforementioned plugging device, the base of said plugging device being fixed to the container.

L'invention concerne notamment les dispositifs de bouchage réalisés en matériau polymère et obtenue par un procédé de moulage par injection.The invention relates in particular to plugging devices made of polymer material and obtained by an injection molding process.

Description des modes de réalisationDescription of embodiments

Dans la description et les figures, l'axe X correspond à un axe central du dispositif de bouchage destiné à être positionné orthogonalement au plan de l'orifice à obturer lorsque le dispositif de bouchage est en position de fermeture. L'axe X correspond ainsi à l'axe de rotation du bouchon du dispositif de bouchage lorsque celui-ci est vissé sur le col 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. 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 du col est dirigé vers le haut et le bouchon est en position de fermeture.In the description and the figures, the axis X corresponds to a central axis of the closure device intended to be positioned orthogonally to the plane of the orifice to be closed when the closure device is in the closed position. The axis X thus corresponds to the axis of rotation of the stopper of the stoppering device when the latter is screwed onto the neck 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. The terms "upper" and "lower" are used to define the relative position of one element to another with reference to a position in which the neck hole is facing upwards and the cap is in the closed position .

En relation avec les figures 1 et 3 à 5, il est décrit ci-dessous un dispositif de bouchage 1 selon un premier mode de réalisation. Le dispositif de bouchage 1 est destiné à être fixé à un récipient 2 équipé d'un col 3, notamment représenté sur la figure 2.In relation to the figure 1 And 3 to 5 , a closure device 1 according to a first embodiment is described below. The closure device 1 is intended to be fixed to a container 2 equipped with a neck 3, in particular represented on the picture 2 .

Le dispositif de bouchage 1 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 1 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 3 du récipient 2.The closure device 1 is molded in a single piece of synthetic material, such as polyethylene and advantageously high density polyethylene. Advantageously, the closure device 1 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 3 of the container 2.

Comme représenté sur la figure 2, le col 3 du récipient 2 comporte une extrémité supérieure dans laquelle est ménagé un orifice 4 permettant de déverser le contenu du récipient 2. Le col 3 du récipient 2 comporte un collier de support 5 qui fait saillie radialement vers l'extérieur et une collerette d'accrochage 6 qui fait également saillie radialement vers l'extérieur et qui est disposé axialement entre le collier de support 5 et l'orifice 4. Dans le mode de réalisation représenté, le col 3 comporte, en outre, positionné axialement entre la collerette d'accrochage 6 et l'orifice 4, un filetage hélicoïdal 7 qui est destiné à coopérer avec un filetage hélicoïdal formé sur le bouchon 8 du dispositif de bouchage 1.As shown on the figure 2 , the neck 3 of the container 2 has an upper end in which is made an orifice 4 allowing the contents of the container 2 to be poured out. The neck 3 of the container 2 has a support collar 5 which projects radially outwards and a collar attachment 6 which also projects radially outwards and which is arranged axially between the support collar 5 and the orifice 4. In the embodiment shown, the neck 3 further comprises, positioned axially between the collar attachment 6 and the orifice 4, a helical thread 7 which is intended to cooperate with a helical thread formed on the plug 8 of the plugging device 1.

Le dispositif de bouchage 1 comporte une base 9 qui est destinée à être fixée au col 3 du récipient 2, un bouchon 8 qui est destiné à recouvrir l'orifice 4 du récipient 2 de manière à l'obturer et un dispositif d'articulation liant le bouchon 8 à la base 9.The stopper device 1 comprises a base 9 which is intended to be fixed to the neck 3 of the container 2, a stopper 8 which is intended to cover the orifice 4 of the container 2 so as to close it and a hinge device linking cap 8 to base 9.

Comme représenté notamment sur la figure 1, le bouchon 8 comporte une paroi supérieure 10 destinée à être disposée sensiblement orthogonalement à l'axe X, en regard de l'orifice 4 du col 3 lorsque ledit bouchon 8 est dans une position de fermeture. Le bouchon 8 comporte, en outre, une jupe périphérique externe 11 qui s'étend, vers le bas, perpendiculairement à la paroi supérieure 10, depuis la périphérie externe de ladite paroi supérieure 10. Dans le mode de réalisation des figures 1 et 2 à 5, la jupe périphérique externe 11 est destinée à entourer le col 3 du récipient 2 lorsque le bouchon 8 est en position de fermeture. La jupe périphérique externe 11 comporte en outre un filetage hélicoïdal 12 qui est ménagé sur sa face interne.As shown in particular on the figure 1 , the stopper 8 has an upper wall 10 intended to be arranged substantially orthogonally to the axis X, opposite the orifice 4 of the neck 3 when said stopper 8 is in a closed position. The cap 8 further comprises an outer peripheral skirt 11 which extends, downwards, perpendicular to the upper wall 10, from the outer periphery of said upper wall 10. In the embodiment of the figure 1 And 2 to 5 , the outer peripheral skirt 11 is intended to surround the neck 3 of the container 2 when the stopper 8 is in the closed position. The outer peripheral skirt 11 further comprises a helical thread 12 which is provided on its inner face.

Comme représenté notamment sur la figure 4, le bouchon 8 comporte une jupe interne 13, qui s'étend perpendiculairement vers le bas depuis la paroi supérieure 10 du bouchon 8 et est dimensionnée de manière à s'insérer à l'intérieur de l'orifice 4 du col 3. Le bouchon 8 comporte en outre une lèvre annulaire 14 qui s'étend, depuis la paroi supérieure 10, radialement entre la jupe interne 13 et la jupe périphérique externe 11. La jupe interne 13 et la lèvre annulaire 14 sont dimensionnées de telle sorte que, lorsque le bouchon 8 est en position de fermeture, sur le col 3 du récipient 2, la jupe interne 13 est en contact contre la face interne du col 3 tandis que la lèvre annulaire 14 est en contact contre la face externe du col 3. Ainsi, la jupe interne 13 et la lèvre annulaire 14 permettent d'assurer l'étanchéité de la fermeture.As shown in particular on the figure 4 , cap 8 has an inner skirt 13, which extends perpendicularly downward from top wall 10 of cap 8 and is sized to fit inside of the orifice 4 of the neck 3. The stopper 8 further comprises an annular lip 14 which extends, from the upper wall 10, radially between the inner skirt 13 and the outer peripheral skirt 11. The inner skirt 13 and the lip ring 14 are dimensioned such that, when the stopper 8 is in the closed position, on the neck 3 of the container 2, the internal skirt 13 is in contact against the internal face of the neck 3 while the annular lip 14 is in contact against the external face of the neck 3. Thus, the internal skirt 13 and the annular lip 14 make it possible to ensure the tightness of the closure.

Dans ce premier mode de réalisation, la base 9 est constituée par une bague inférieure 15 qui est retenue sur le col 3 du récipient 2. La bague inférieure 15 est maintenue axialement sur le col 3 du récipient 2 tout en pouvant tourner par rapport à celui-ci autour de l'axe X. Comme représenté sur la figure 3, la bague inférieure 15 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 15 est liée au bouchon 8 au moyen du dispositif d'articulation. Le deuxième secteur 17 est apte à pivoter vers le haut par rapport au premier secteur 16, entre une position abaissée dans laquelle le deuxième secteur 17 est destiné à être disposé en-dessous de la collerette d'accrochage 6 et une position relevée, dans laquelle le deuxième secteur 17 est disposé au moins en partie au-dessus de la collerette d'accrochage 6. Ceci autorise le bouchon 8 à se déplacer vers le haut par rapport au col 3 du récipient 2, jusqu'à ce que le filetage hélicoïdal 12 du bouchon 8 se désengage du filetage hélicoïdal 7 ménagé sur le col 3 du récipient 2. En d'autres termes, lorsque le bouchon 8 est dévissé, la bague inférieure 15 est entraînée en rotation autour de l'axe X tandis que le deuxième secteur 17 de la bague inférieure 15 pivote par rapport au premier secteur 16 jusqu'à la position relevée de sorte à autoriser un mouvement axial, vers le haut du bouchon 8, de la position de fermeture, jusqu'à une position libérée représentée sur la figure 3. Lorsque le bouchon 8 est pivoté de la position libérée vers la position basculée ouverte, représentée sur la figure 4, le deuxième secteur 17 de la bague inférieure 15 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 8 est pivoté de la position basculée ouverte vers la position libérée.In this first embodiment, the base 9 is constituted by a lower ring 15 which is retained on the neck 3 of the container 2. The lower ring 15 is held axially on the neck 3 of the container 2 while being able to rotate relative to that around the X axis. As shown in the picture 3 , the lower ring 15 comprises two parts which are hinged to one another, namely a first sector 16 and a second sector 17 by which the lower ring 15 is connected to the stopper 8 by means of the hinge device. The second sector 17 is capable of pivoting upwards with respect to the first sector 16, between a lowered position in which the second sector 17 is intended to be arranged below the attachment collar 6 and a raised position, in which the second sector 17 is arranged at least partly above the attachment flange 6. This allows the stopper 8 to move upwards relative to the neck 3 of the container 2, until the helical thread 12 of the cap 8 disengages from the helical thread 7 provided on the neck 3 of the container 2. In other words, when the cap 8 is unscrewed, the lower ring 15 is driven in rotation around the axis X while the second sector 17 of the lower ring 15 pivots with respect to the first sector 16 to the raised position so as to allow an axial movement, upwards of the stopper 8, from the closed position, to a released position represented on the picture 3 . When the cap 8 is pivoted from the released position to the open tilted position, shown in the figure 4 , the second sector 17 of the lower ring 15 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 8 is pivoted from the open tilted position to the released position.

La bague inférieure 15 est maintenue axialement sur le col 3 du récipient 2 au moyen de la collerette d'accrochage 6. Comme représenté sur la figure 2, la collerette d'accrochage 6 présente une surface externe tronconique se rétrécissant vers le haut, c'est-à-dire en direction de l'orifice 4 du récipient 2. La collerette d'accrochage 6 délimite, vers le bas, c'est-à-dire dans une direction opposée à l'orifice 4, un épaulement.The lower ring 15 is held axially on the neck 3 of the container 2 by means of the attachment flange 6. As shown in the picture 2 , the attachment collar 6 has a frustoconical outer surface tapering upwards, that is to say in the direction of the orifice 4 of the container 2. The attachment collar 6 delimits, downwards, it that is to say in a direction opposite to the orifice 4, a shoulder.

Comme représenté sur la figure 1, le premier secteur 16 de la bague inférieure 15 comporte des éléments d'accrochage 18 qui coopèrent avec la collerette d'accrochage 6 ménagée sur le récipient 2 afin de retenir axialement la bague inférieure 15 au col 3 du récipient 2. Les éléments d'accrochage 18 sont des protubérances qui font saillie radialement vers l'intérieur depuis le premier secteur 16 de la bague inférieure 15. Lors de l'assemblage du dispositif de bouchage 1 sur le col 3 du récipient 2, les éléments d'accrochage 18 glissent contre la surface tronconique de la collerette d'accrochage 6 puis se verrouillent par rappel élastique derrière la collerette d'accrochage 6.As shown on the figure 1 , the first sector 16 of the lower ring 15 comprises attachment elements 18 which cooperate with the attachment collar 6 provided on the container 2 in order to axially retain the lower ring 15 at the neck 3 of the container 2. The elements of attachment 18 are protuberances which project radially inwards from the first sector 16 of the lower ring 15. When the closure device 1 is assembled on the neck 3 of the container 2, the attachment elements 18 slide against the frustoconical surface of the attachment flange 6 then lock by elastic return behind the attachment flange 6.

De manière avantageuse, la bague inférieure 15 est, avant la première ouverture du récipient 2, reliée au bouchon 8 par des ponts frangibles, non visibles sur les figures, destinés à se rompre lors de l'ouverture du bouchon 8. Ces ponts frangibles constituent ainsi des témoins d'inviolabilité.Advantageously, the lower ring 15 is, before the first opening of the container 2, connected to the stopper 8 by frangible bridges, not visible in the figures, intended to break when the stopper 8 is opened. These frangible bridges constitute thus witnesses of inviolability.

Le dispositif d'articulation autorise le mouvement du bouchon 8 entre la position libérée, représentée sur la figure 3, dans laquelle, le bouchon 8 n'est plus en prise avec le col 3 et la position basculée ouverte, représentée sur la figure 4, dans laquelle le bouchon 8 est dégagé de l'orifice 4 du col 3 de manière à ce qu'il ne gêne pas le déversement du contenu du récipient 2.The hinge device allows the movement of the stopper 8 between the released position, represented on the picture 3 , in which the stopper 8 is no longer in engagement with the neck 3 and the open tilted position, represented on the figure 4 , in which the stopper 8 is disengaged from the orifice 4 of the neck 3 so that it does not interfere with the discharge of the contents of the container 2.

En relation avec la figure 5, on décrit ci-dessous le dispositif d'articulation. Le dispositif d'articulation comporte deux lamelles 19, 20 qui relient le bouchon 8, et plus particulièrement la jupe périphérique externe 11, à la bague inférieure 15, et plus particulièrement au deuxième secteur 17 de la bague inférieure 15.In relation to the figure 5 , the hinge device is described below. The hinge device comprises two slats 19, 20 which connect the plug 8, and more particularly the outer peripheral skirt 11, to the lower ring 15, and more particularly to the second sector 17 of the lower ring 15.

La jupe périphérique externe 11 comporte deux portions échancrées 21, 22. Chaque portion échancrée 21, 22 est définie par un bord supérieur 23 s'étendant circonférentiellement autour de l'axe X, à distance du bord inférieur 24 de la jupe périphérique externe 11, et par deux bords latéraux 25, 26 s'étendant respectivement depuis l'une et l'autre des deux extrémités du bord supérieur 23 et rejoignant le bord inférieur 24 de la jupe périphérique externe 11. Les lamelles 19, 20 rejoignent chacune le bord supérieur 23 de l'une des portions échancrées 21, 22. De même, la bague inférieure 15 comporte également deux portions échancrées 27, 28 et les lamelles 19, 20 rejoignent la bague inférieure 15 à l'intérieur de la portion échancrée 27, 28. Ainsi, l'extrémité supérieure des lamelles 19, 20 est située au-dessus du bord inférieur 24 de la jupe périphérique externe 11 et l'extrémité inférieure des lamelles 19, 20 est située en-dessous du bord supérieur de la bague inférieure 15. Cet agencement confère aux lamelles 19, 20 une longueur suffisante pour autoriser le basculement du bouchon 8 vers sa position basculée ouverte tout en limitant la dimension de l'interstice circonférentiel ménagé entre le bouchon 8 et la bague inférieure 15.The outer peripheral skirt 11 comprises two indented portions 21, 22. Each indented portion 21, 22 is defined by an upper edge 23 extending circumferentially around the axis X, at a distance from the lower edge 24 of the outer peripheral skirt 11, and by two side edges 25, 26 extending respectively from one and the other of the two ends of the upper edge 23 and joining the lower edge 24 of the outer peripheral skirt 11. The slats 19, 20 each join the upper edge 23 of one of the indented portions 21, 22. Similarly, the lower ring 15 also comprises two indented portions 27, 28 and the blades 19, 20 join the lower ring 15 inside the indented portion 27, 28. Thus, the upper end of the slats 19, 20 is located above the lower edge 24 of the outer peripheral skirt 11 and the lower end of the slats 19, 20 is located below the upper edge of the lower ring 15. This arrangement gives the slats 19, 20 a sufficient length to allow the cap 8 to tilt towards its open tilted position while limiting the size of the circumferential gap provided between the cap 8 and the lower ring 15.

Par ailleurs, le bouchon 8 comporte deux voiles anti-intrusion 29, 30 qui s'étendent à l'intérieur de chaque portion échancrée 21, 22, respectivement de part et d'autre de l'une des lamelles 19, 20, afin de recouvrir au moins partiellement ladite portion échancrée 21, 22. De tels voiles anti-intrusion 29, 30 permettent ainsi d'empêcher les corps extérieurs, tels que les particules, poussières ou organismes indésirables, insectes ou larves par exemple, de venir se loger dans les portions échancrées 21, 22. Ils permettent ainsi de garantir l'hygiène et la sécurité du dispositif de bouchage 1.Furthermore, the cap 8 comprises two anti-intrusion webs 29, 30 which extend inside each indented portion 21, 22, respectively on either side of one of the slats 19, 20, in order to at least partially cover said indented portion 21, 22. Such anti-intrusion veils 29, 30 thus make it possible to prevent external bodies, such as particles, dust or undesirable organisms, insects or larvae for example, from becoming lodged in the indented portions 21, 22. They thus make it possible to guarantee the hygiene and safety of the closure device 1.

Chaque voile anti-intrusion 29, 30 est lié au bord supérieur 23 et à l'un des bords latéraux 25, 26 de l'une des portions échancrées 21, 22. Chaque voile anti-intrusion 29, 30 comporte en outre un bord libre latéral 31 et un bord libre inférieur 32 qui se rejoignent. Le bord libre inférieur 32 s'étend depuis l'extrémité inférieure de l'un des bords latéraux 25, 26 dans le prolongement du bord inférieur 24 de la jupe périphérique externe 11. Le bord libre latéral 31 s'étend, parallèlement à la lamelle 19, 20 adjacente. Le bord libre latéral 31 est écarté de la lamelle 19, 20 d'un interstice dont la largeur est comprise entre 0,01 et 0,4 mm. Ainsi, l'interstice présente une largeur suffisamment faible pour empêcher la majeure partie des corps extérieurs de venir s'y loger tout en étant suffisamment important pour ne pas risquer de perturber les fonctionnalités des lamelles 19, 20 et pour être compatible avec les contraintes du procédé de moulage.Each anti-intrusion veil 29, 30 is linked to the upper edge 23 and to one of the side edges 25, 26 of one of the indented portions 21, 22. Each anti-intrusion veil 29, 30 further comprises a free edge side 31 and a lower free edge 32 which meet. The lower free edge 32 extends from the lower end of one of the side edges 25, 26 in the extension of the lower edge 24 of the outer peripheral skirt 11. The free side edge 31 extends, parallel to the strip 19, 20 adjacent. The lateral free edge 31 is separated from the strip 19, 20 by a gap whose width is between 0.01 and 0.4 mm. Thus, the interstice presents a width sufficiently small to prevent the major part of the external bodies from coming to lodge there while being sufficiently large not to risk disturbing the functionalities of the slats 19, 20 and to be compatible with the constraints of the molding process.

Les voiles anti-intrusion 29, 30 présentent une épaisseur inférieure à celle de la jupe périphérique externe 11, ce qui est particulièrement avantageux. En effet, plus l'épaisseur des voiles anti-intrusion 29, 30 est faible et plus les contraintes s'exerçant, lors des opérations de moulage, sur chaque lame du moule destinée à ménager l'interstice entre l'un des voiles anti-intrusion 29, 30 et la lamelle adjacente 19, 20 sont faibles. Compte-tenu des contraintes moindres exercées sur lesdites lames, elles peuvent présenter une épaisseur moindre, ce qui, par conséquent, permet de diminuer la largeur de l'interstice ménagé entre les voiles anti-intrusion 29, 30 et les lamelles 19, 20. Ainsi, les voiles anti-intrusion 29, 30 présentent avantageusement une épaisseur comprise entre 0,05 et 0,5 mm.The anti-intrusion webs 29, 30 have a thickness less than that of the outer peripheral skirt 11, which is particularly advantageous. Indeed, the lower the thickness of the anti-intrusion veils 29, 30, the greater the stresses exerted, during the molding operations, on each blade of the mold intended to create the gap between one of the anti-intrusion veils. intrusion 29, 30 and adjacent lamella 19, 20 are weak. Given the lower stresses exerted on said slats, they may have a lower thickness, which consequently makes it possible to reduce the width of the gap provided between the anti-intrusion webs 29, 30 and the slats 19, 20. Thus, the anti-intrusion webs 29, 30 advantageously have a thickness of between 0.05 and 0.5 mm.

Par ailleurs, à titre d'exemple, dans le mode de réalisation représenté, le dispositif de blocage comporte un talon 32, notamment visible sur les figures 1, 3 et 5, qui est ménagé dans la jupe périphérique externe 11 du bouchon 8. Le talon 32 est disposé entre les portions échancrées 21, 22. L'extrémité inférieure du talon est avantageusement située à la même hauteur que l'extrémité inférieure de la jupe périphérique externe 11. Le talon 32 comporte un taquet 33 qui s'étend circonférentiellement autour de l'axe X et qui fait saillie radialement vers l'extérieur depuis le talon 32.Furthermore, by way of example, in the embodiment represented, the locking device comprises a heel 32, in particular visible on the figure 1 , 3 And 5 , which is formed in the outer peripheral skirt 11 of the cap 8. The heel 32 is arranged between the indented portions 21, 22. The lower end of the heel is advantageously located at the same height as the lower end of the outer peripheral skirt 11. Heel 32 has a cleat 33 which extends circumferentially around the X-axis and projects radially outward from heel 32.

Lors du mouvement du bouchon 8 de la position libérée vers la position basculée ouverte, le taquet 33 vient en appui contre l'extrémité supérieure du deuxième secteur 17 de la bague inférieure 15 ce qui tend à ramener ledit deuxième secteur 17 vers la position abaissée. En outre, lorsque le deuxième secteur 17 de la bague inférieure 15 est dans la position abaissée et que le bouchon 8 est dans sa position basculée ouverte, le taquet 33 est en appui contre la collerette d'accrochage 6. Ainsi, le bouchon 8 demeure dans sa position basculée ouverte puisque, en raison de cet appui du taquet 33 contre la collerette d'accrochage 6, le bouchon 8 ne peut pas être pivoté vers la position libérée dans laquelle le bouchon 8 est en regard de l'orifice 4 tant que le deuxième secteur 17 de la bague inférieure 15 reste dans la position abaissée.During the movement of the stopper 8 from the released position to the open tilted position, the cleat 33 comes to bear against the upper end of the second sector 17 of the lower ring 15 which tends to bring said second sector 17 back to the lowered position. In addition, when the second sector 17 of the lower ring 15 is in the lowered position and the cap 8 is in its open tilted position, the cleat 33 bears against the attachment collar 6. Thus, the cap 8 remains in its open tilted position since, because of this support of the cleat 33 against the attachment collar 6, the cap 8 cannot be pivoted towards the released position in which the cap 8 is facing the orifice 4 as long as the second sector 17 of the lower ring 15 remains in the lowered position.

Notons que le dispositif de blocage décrit ci-dessus n'est décrit qu'à titre d'exemple et que le dispositif de bouchage 1 peut être équipé d'un autre type dispositif de blocage ou tout simplement ne pas être équipé d'un dispositif de blocage sans pour autant sortir du cadre de l'invention, telle que définie par les revendications.Note that the blocking device described above is only described by way of example and that the plugging device 1 can be equipped with another type of blocking device or quite simply not be equipped with a device. blocking without departing from the scope of the invention, as defined by the claims.

De même, si le dispositif de bouchage 1 décrit ci-dessus comporte un bouchon 8 apte à être vissé sur le col 3 du récipient 2, l'invention est également applicable à des bouchons destinés à se clipser sur le col 3 du récipient 2, tels que décrits par exemple dans les documents EP1406820 et US2018086510 .Similarly, if the stopper device 1 described above comprises a stopper 8 capable of being screwed onto the neck 3 of the container 2, the invention is also applicable to stoppers intended to be clipped onto the neck 3 of the container 2, as described for example in the documents EP1406820 And US2018086510 .

Les figures 6 et 7 illustrent un dispositif de bouchage 101 selon un second mode de réalisation. Les éléments identiques ou analogues aux éléments des figures 1 à 5, c'est-à-dire remplissant la même fonction, portent le même chiffre de référence augmenté de 100.THE figure 6 And 7 illustrate a closure device 101 according to a second embodiment. Elements identical or similar to the elements of the figures 1 to 5 , that is to say fulfilling the same function, carry the same reference number increased by 100.

Le dispositif de bouchage 101 comporte un élément verseur 134, visible sur la figure 7, qui est destiné à être solidarisé au col 3 d'un récipient 2. L'élément verseur 134 comporte une jupe annulaire 135 qui est destiné à entourer le col 3 du récipient 2 et à y être fixé. Pour ce faire, la jupe annulaire 135 comporte des éléments d'accrochage 136 qui sont destinés à coopérer avec une collerette d'accrochage 6 faisant saillie radialement du col 3 du récipient 2. L'élément verseur 134 comporte également une jupe interne 136 qui est dimensionnée pour venir s'insérer à l'intérieur de l'orifice 4 du col 3 et est configuré pour assurer une étanchéité entre l'élément verseur 134 et l'orifice 4 du récipient 2. L'élément verseur 134 comporte également un bec verseur 137 équipé d'un orifice 138 permettant de déverser le contenu du récipient 2.The closure device 101 comprises a pouring element 134, visible on the figure 7 , which is intended to be secured to the neck 3 of a container 2. The pouring element 134 comprises an annular skirt 135 which is intended to surround the neck 3 of the container 2 and to be fixed there. To do this, the annular skirt 135 comprises attachment elements 136 which are intended to cooperate with an attachment flange 6 projecting radially from the neck 3 of the container 2. The pouring element 134 also comprises an internal skirt 136 which is dimensioned to be inserted inside the orifice 4 of the neck 3 and is configured to ensure a seal between the pouring element 134 and the orifice 4 of the container 2. The pouring element 134 also comprises a pouring spout 137 equipped with an orifice 138 allowing the contents of container 2 to be discharged.

L'élément verseur 134 comporte en outre une gorge annulaire 139 qui est ménagée à l'extérieur de la jupe annulaire 135. Le dispositif de bouchage 101 comporte une bague inférieure 115 qui est destinée à venir se fixer à l'intérieur de la gorge annulaire 139 de l'élément verseur 134 par des moyens de clipsage 140, tels que représentés sur la figure 7. L'élément verseur 134 et la bague inférieure 115 forment ensemble une base 109 destinée à venir se fixer au col 3 du récipient 2.The pouring element 134 further comprises an annular groove 139 which is formed outside the annular skirt 135. The stopper device 101 comprises a lower ring 115 which is intended to be fixed inside the annular groove 139 of the pouring element 134 by clipping means 140, such than represented on the figure 7 . The pouring element 134 and the lower ring 115 together form a base 109 intended to be fixed to the neck 3 of the container 2.

Le dispositif de bouchage 101 comporte également un bouchon 108 qui est destiné à venir recouvrir l'orifice de l'élément verseur 134 de manière à l'obturer ainsi qu'un dispositif d'articulation liant le bouchon 108 à la base 9 et plus particulièrement à la bague inférieure 115.The stopper device 101 also comprises a stopper 108 which is intended to cover the orifice of the pouring element 134 so as to close it as well as a hinge device linking the stopper 108 to the base 9 and more particularly to the lower ring 115.

Le bouchon 108 comporte une paroi supérieure 110 destinée à être disposée sensiblement orthogonalement à l'axe X, en regard de l'orifice de l'élément verseur 134 lorsque ledit bouchon 108 est dans une position de fermeture. Le bouchon 108 comporte, en outre, une jupe périphérique externe 111 qui s'étend, vers le bas, depuis la périphérie externe de ladite paroi supérieure 110. La jupe périphérique externe 111 est destinée à entourer l'élément verseur 134 lorsque le bouchon 108 est en position de fermeture.The stopper 108 comprises an upper wall 110 intended to be arranged substantially orthogonal to the axis X, opposite the orifice of the pouring element 134 when said stopper 108 is in a closed position. The stopper 108 further comprises an outer peripheral skirt 111 which extends, downwards, from the outer periphery of said upper wall 110. The outer peripheral skirt 111 is intended to surround the pouring element 134 when the stopper 108 is in the closed position.

Comme représenté sur la figure 7, le bouchon 108 comporte une lèvre annulaire interne 141 qui s'étend perpendiculairement vers le bas depuis la paroi supérieure 110 du bouchon 108 et est dimensionnée de manière à s'insérer à l'intérieur de l'orifice 138 de l'élément verseur 134. Le bouchon 108 comporte en outre une lèvre annulaire externe 142 qui s'étend vers le bas, depuis la paroi supérieure, et est disposée radialement entre lèvre annulaire interne 141 et la jupe périphérique externe 111. La lèvre annulaire externe 142 et la lèvre annulaire interne 141 sont dimensionnées de telle sorte que, lorsque le bouchon 108 est en position de fermeture, la lèvre annulaire interne 141 est en contact contre la face interne du bec verseur 137 tandis que la lèvre annulaire externe 142 est en contact contre la face externe du bec verseur 137 ce qui permet d'assurer une étanchéité entre le bouchon 108 et le bec verseur 137.As shown on the figure 7 , stopper 108 has an inner annular lip 141 which extends perpendicularly downward from top wall 110 of stopper 108 and is sized to fit within orifice 138 of pouring member 134 The plug 108 further includes an outer annular lip 142 which extends downward from the top wall and is disposed radially between the inner annular lip 141 and the outer peripheral skirt 111. The outer annular lip 142 and the annular lip internal 141 are dimensioned such that, when the stopper 108 is in the closed position, the internal annular lip 141 is in contact against the internal face of the spout 137 while the external annular lip 142 is in contact against the external face of the pouring spout 137 which makes it possible to ensure a seal between the stopper 108 and the pouring spout 137.

Comme dans le mode de réalisation précédent, le dispositif de bouchage 101 comporte un dispositif de blocage agencé pour bloquer le bouchon 108 dans une position basculée ouverte, non représentée. Dans le mode de réalisation représenté, le dispositif de blocage comporte un talon 132 qui est ménagé dans la jupe périphérique externe 111 du bouchon 108. Le talon 135 est disposé entre deux portions échancrées 121, 122 ménagées dans la jupe périphérique externe 111. L'extrémité inférieure du talon 132 est ici située en-dessous du bord inférieur 124 de la jupe périphérique externe 111. Le talon 132 comporte un taquet 133 qui s'étend circonférentiellement autour de l'axe X et qui fait saillie radialement vers l'extérieur depuis le talon 132. Le taquet 133 est configuré pour venir en appui contre l'élément verseur 134, et plus particulièrement contre une collerette de blocage 143 de l'élément verseur 134, lorsque le bouchon 108 est dans la position basculée ouverte, de manière à bloquer le bouchon 108 dans cette position.As in the previous embodiment, the stopper device 101 includes a locking device arranged to lock the stopper 108 in an open tilted position, not shown. In the embodiment shown, the locking device comprises a heel 132 which is made in the outer peripheral skirt 111 of the stopper 108. The heel 135 is arranged between two indented portions 121, 122 made in the outer peripheral skirt 111. The lower end of the heel 132 is here located below the lower edge 124 of the outer peripheral skirt 111. The heel 132 includes a cleat 133 which extends circumferentially around the axis X and which projects radially towards the outside from the heel 132. The catch 133 is configured to bear against the pouring element 134, and more particularly against a locking collar 143 of the pouring element 134, when the stopper 108 is in the open tilted position, so as to block the stopper 108 in this position.

Le dispositif d'articulation est illustré sur la figure 6. Comme dans le mode de réalisation précédent, le dispositif d'articulation comporte deux lamelles 119, 120 qui relient la jupe périphérique externe 111 du bouchon 108 à la bague inférieure 115. En outre, la jupe périphérique externe 111 comporte deux portions échancrées 121, 122. Chaque portion échancrée 121, 122 est définie par un bord supérieur 123 et par deux bords latéraux 125, 126 s'étendant respectivement depuis l'une et l'autre des deux extrémités du bord supérieur 123 et rejoignant respectivement le bord inférieur 124 de la jupe périphérique externe 111 et le bord inférieur du talon 132. Dans ce mode de réalisation, le bord supérieur 123 ne s'étend pas horizontalement comme dans le mode de réalisation précédent mais est incliné par rapport à l'horizontal et descend pour rejoindre le talon 132. L'extrémité du bord supérieur 123 de la portion échancrée 121, 122 qui rejoint le talon 132 est disposée sensiblement à la même hauteur que le bord inférieur 124 de la jupe périphérique externe 111, en dehors de la zone du talon 132.The articulation device is illustrated in the figure 6 . As in the previous embodiment, the hinge device comprises two slats 119, 120 which connect the outer peripheral skirt 111 of the stopper 108 to the lower ring 115. In addition, the outer peripheral skirt 111 comprises two indented portions 121, 122 Each indented portion 121, 122 is defined by an upper edge 123 and by two side edges 125, 126 extending respectively from one and the other of the two ends of the upper edge 123 and respectively joining the lower edge 124 of the outer peripheral skirt 111 and the lower edge of the heel 132. In this embodiment, the upper edge 123 does not extend horizontally as in the previous embodiment but is inclined with respect to the horizontal and descends to join the heel 132. The end of the upper edge 123 of the indented portion 121, 122 which joins the heel 132 is arranged substantially at the same height as the lower edge 124 of the outer peripheral skirt 111, outside the heel zone 132.

Le bouchon 108 comporte un voile anti-intrusion 129 qui s'étend à l'intérieur de chaque portion échancrée 121, 122 afin d'en recouvrir une zone de sorte à empêcher des corps extérieurs de venir s'y loger. Chaque voile anti-intrusion 129 est disposé, par rapport à la lamelle 119, 120 du côté opposé au talon 132, c'est-à-dire dans la zone de la portion échancrée 121 qui est située au-dessus du bord inférieur 124 de la jupe périphérique externe 111, hors de la zone de talon 132. Nous observons, que, dans ce mode de réalisation, la zone de chaque portion échancrée 121, 122 qui est située entre la lamelle 119, 120 et le talon 132 ne s'étend pas au-dessus du bord inférieur 124 de la jupe périphérique externe 111 de sorte qu'aucun voile anti-intrusion 129 disposé dans cette zone n'est nécessaire.The cap 108 comprises an anti-intrusion veil 129 which extends inside each indented portion 121, 122 in order to cover a zone thereof so as to prevent external bodies from becoming lodged therein. Each anti-intrusion veil 129 is arranged, with respect to the slat 119, 120 on the side opposite the heel 132, that is to say in the zone of the indented portion 121 which is located above the lower edge 124 of the outer peripheral skirt 111, out of the heel zone 132. We observe that, in this embodiment, the zone of each indented portion 121, 122 which is located between the sipe 119, 120 and the heel 132 does not does not extend above the lower edge 124 of the outer peripheral skirt 111 so that no anti-intrusion veil 129 placed in this zone is necessary.

Chaque voile anti-intrusion 129 est lié au bord supérieur 123 de la portion échancrée 121, 122, à la lamelle 119, 120 et au bord latéral 125 de la portion échancrée 121, 122 qui est opposé au talon 132. Le voile anti-intrusion 129 comporte un bord libre inférieur 132 qui s'étend dans le prolongement du bord inférieur 124 de la jupe périphérique externe 111. Par ailleurs, on note que, dans ce mode de réalisation, le voile anti-intrusion 129 est également lié à l'une des lamelles 119, 120 de sorte qu'il n'y a pas d'interstice entre ladite lamelle 119, 120 et le voile anti-intrusion 129 comme dans le mode de réalisation précédent. Aussi, le voile anti-intrusion 129 présente avantageusement une épaisseur inférieure à celle de la lamelle 119, 120 et à celle de la jupe périphérique externe 111 de sorte à affecter le moins possible le fonctionnement de l'articulation. L'épaisseur du voile anti-intrusion 129 est par exemple comprise entre 0,05 et 0,5 mm.Each anti-intrusion veil 129 is linked to the upper edge 123 of the indented portion 121, 122, to the strip 119, 120 and to the side edge 125 of the indented portion 121, 122 which is opposite the heel 132. The anti-intrusion veil 129 comprises a lower free edge 132 which extends in the extension of the lower edge 124 of the outer peripheral skirt 111. Furthermore, it is noted that, in this embodiment, the anti-intrusion veil 129 is also linked to the one of the slats 119, 120 so that there is no gap between said slat 119, 120 and the anti-intrusion veil 129 as in the previous embodiment. Also, the anti-intrusion veil 129 advantageously has a thickness less than that of the lamella 119, 120 and that of the outer peripheral skirt 111 so as to affect the operation of the joint as little as possible. The thickness of the anti-intrusion veil 129 is for example between 0.05 and 0.5 mm.
