Description

L'invention a trait à un dispositif de bouchage d'un récipient et à un récipient pourvu d'un tel dispositif.The invention relates to a device for capping a container and to a container provided with such a device.

Dans le domaine du conditionnement de liquides, il est connu d'équiper le col fileté ou non fileté d'une bouteille avec un dispositif de bouchage en matière plastique comprenant un bouchon articulé sur une jupe, elle-même prévue pour être immobilisée autour de ce col. Une bande ou des pontets sécables peut relier le bouchon à la jupe avant la première ouverture de la bouteille. Lorsque le bouchon est basculé de sa position de fermeture vers une position ouverte, il n'est généralement pas tenu par rapport à la jupe de sorte que, selon le sens d'inclinaison du récipient, il peut interférer avec le liquide qui s'écoule à partir du col. Un tel bouchon peut également être gênant pour un utilisateur désirant boire au goulot d'une bouteille, notamment pour des applications dans le domaine des eaux minérales ou des yaourts à boire.In the field of liquid conditioning, it is known to equip the threaded or non-threaded neck of a bottle with a plastic closure device comprising a cap hinged to a skirt, itself intended to be immobilized around it. collar. A band or breakable bridges can connect the cap to the skirt before the first opening of the bottle. When the cap is swung from its closed position to an open position, it is generally not held with respect to the skirt so that, depending on the direction of inclination of the container, it may interfere with the liquid flowing from the neck. Such a stopper can also be inconvenient for a user wishing to drink from the neck of a bottle, especially for applications in the field of mineral water or yoghurt drinks.

Dans certains dispositifs, tels que ceux connus de US-A-4,158, 902, de US-A-S., 088, 612 ou de US-A-5,271,536, il est prévu des languettes permettant de constituer un point dur pour stabiliser un bouchon articulé dans une position faisant un angle d'environ 90° par rapport à sa position de fermeture d'un récipient. Dans cette position à 90°, le bouchon peut gêner le déversement du contenu du récipient et empêche un utilisateur de boire au goulot. Si le bouchon est basculé vers sa position complètement ouverte, il n'est plus maintenu par rapport au reste du dispositif et peut, là encore, être gênant.In certain devices, such as those known from US-A-4,158, 902, US-AS, 088, 612 or US-A-5,271,536, there are provided tabs for constituting a hard point for stabilizing an articulated plug. in a position making an angle of about 90 ° with respect to its closed position of a container. In this 90 ° position, the stopper can impede the pouring of the contents of the container and prevent a user from drinking at the neck. If the cap is tilted to its fully open position, it is no longer maintained relative to the rest of the device and may again be troublesome.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un dispositif de bouchage dont le bouchon peut être efficacement maintenu en position ouverte, de sorte qu'il ne crée pas de gêne lors de l'utilisation du liquide contenu dans le récipient.It is these drawbacks that the invention intends to remedy more particularly by proposing a capping device whose cap can be effectively maintained in the open position, so that it does not create discomfort when using the liquid contained in the container.

Dans cet esprit, l'invention concerne un dispositif de bouchage d'un récipient pourvu d'un col, ce dispositif comprenant un bouchon en matière plastique articulé sur une jupe destinée à entourer ce col ce bouchon portant dans sa zone d'articulation sur la jupe, au moins une section apte à venir en appui contre un talon prévu à proximité du bord supérieur de la jupe, dans une configuration de blocage du bouchon, caractérisé en ce que la géométrie et le positionnement de la section et du talon précités sont tels que, dans la configuration précitée, le bouchon est bloqué dans une position complètement ouverte du dispositif dans laquelle son angle d'ouverture est supérieur ou égal à 180°.With this in mind, the invention relates to a closure device for a container provided with a neck, this device comprising a plastic stopper articulated on a skirt intended to surround this collar which cap carrying in its articulation zone on the skirt, at least one section adapted to abut against a bead provided near the upper edge of the skirt, in a blocking configuration of the cap, characterized in that the geometry and the positioning of the aforementioned section and heel are such that in the aforementioned configuration, the cap is locked in a fully open position of the device in which its opening angle is greater than or equal to 180 °.

Grâce à l'invention, le bouchon est efficacement maintenu en position complètement ouverte grâce à la coopération de la section et du talon précités. Au sens de la présente invention, la position complètement ouverte du dispositif est celle dans laquelle le bouchon est pivoté vers sa position de basculement dans laquelle il libère le plus l'accès au reste du dispositif et au col du récipient. Cette position complètement ouverte correspond à un angle d'ouverture du bouchon supérieur ou égal à 180°. Dans ces conditions, le bouchon est dégagé du col lors du versement d'un liquide contenu dans le récipient ou lorsqu'une personne souhaite boire à la bouteille. On note que le caractère stable de l'ouverture du bouchon est obtenu sans avoir recours à une charnière pourvue d'un ressort, une telle charnière étant notablement plus compliquée et plus difficile à mouler que le mécanisme de l'invention.Thanks to the invention, the cap is effectively maintained in fully open position through the cooperation of the aforementioned section and heel. In the sense of the present invention, the fully open position of the device is that in which the cap is pivoted to its tilting position in which it releases the most access to the rest of the device and the neck of the container. This fully open position corresponds to an opening angle of the cap greater than or equal to 180 °. Under these conditions, the cap is released from the neck when pouring a liquid contained in the container or when a person wants to drink from the bottle. Note that the stability of the opening of the cap is obtained without resorting to a hinge provided with a spring, such hinge being significantly more complicated and more difficult to mold than the mechanism of the invention.

Selon des aspects avantageux mais non obligatoires de l'invention, le dispositif incorpore une ou plusieurs des caractéristiques suivantes :According to advantageous but non-mandatory aspects of the invention, the device incorporates one or more of the following features:

Selon certains modes de réalisation avantageux de l'invention, la section précitée du bouchon est ménagée entre deux lamelles élastiques qui forment une charnière et relient le bouchon et la jupe. Selon une variante de réalisation de l'invention, deux sections sont prévues sur le bouchon pour venir en appui contre un talon, ces sections étant réparties de part et d'autre d'une lamelle élastique formant charnière et reliant le bouchon et la jupe. Dans tous les cas, l'appui de la section du bouchon sur le talon peut être obtenu par un effort élastique exercé par les lamelles.According to some advantageous embodiments of the invention, the aforementioned section of the plug is formed between two elastic strips which form a hinge and connect the plug and the skirt. According to an alternative embodiment of the invention, two sections are provided on the cap to bear against a heel, these sections being distributed on either side of an elastic strip forming a hinge and connecting the cap and the skirt. In all cases, the support of the cap section on the heel can be obtained by an elastic force exerted by the slats.

Selon un premier mode de réalisation avantageux de l'invention, le talon peut être formé par une partie du bord supérieur du col.According to a first advantageous embodiment of the invention, the heel may be formed by a portion of the upper edge of the neck.

Selon un autre mode de réalisation avantageux de l'invention, le talon peut être formé par une languette monobloc avec la jupe et s'étendant vers le haut à partir de son bord supérieur. Dans ce cas, cette languette peut venir en appui, sous l'effet d'un effort exercé par la section précitée du bouchon, contre la surface radiale externe du col et transmettre à cette section un effort de réaction généré par le col.According to another advantageous embodiment of the invention, the heel may be formed by a one-piece tongue with the skirt and extending upwards from its upper edge. In this case, this tongue may come into abutment, under the effect of a force exerted by the aforementioned section of the plug, against the radial outer surface of the neck and transmit to this section a reaction force generated by the neck.

Un tel bouchon peut avoir une forme externe bombée pour lui conférer un aspect esthétique satisfaisant et éviter l'accumulation de liquide ou de salissures sur sa surface supérieure. Lorsqu'un tel bouchon a été ouvert, il est parfois difficile de le rabattre vers sa position de fermeture du col du récipient car les doigts d'un utilisateur glissent sur le bord du bouchon opposé à sa zone d'articulation sur la jupe. En particulier, il est souvent nécessaire de fermer une bouteille avec les deux mains, en tenant le goulot de la bouteille à une main, alors que l'on exerce avec l'autre main un effort de fermeture du dispositif de bouchage.Such a cap may have a convex outer shape to give it a satisfactory aesthetic appearance and prevent the accumulation of liquid or dirt on its upper surface. When such a cap has been opened, it is sometimes difficult to fold to its closed position of the neck of the container because the fingers of a user slide on the edge of the cap opposite its hinge area on the skirt. In particular, it is often necessary to close a bottle with both hands, holding the neck of the bottle with one hand, while exercising with the other hand a closing force of the closure device.

Pour certains types de boissons, il est souhaitable de pouvoir fermer un dispositif de bouchage de façon particulièrement aisée, par exemple avec une seule main, et les dispositifs connus ne donnent pas satisfaction dans ces conditions.For certain types of drinks, it is desirable to be able to close a closure device in a particularly easy manner, for example with one hand, and the known devices are unsatisfactory under these conditions.

Pour résoudre ce problème, selon un aspect avantageux de l'invention le bouchon a une face externe convexe sur la plus grande partie de sa surface, alors que cette face externe est pourvue d'une dépression concave ménagée sensiblement à l'opposé de la zone d'articulation du bouchon sur la jupe.To solve this problem, according to an advantageous aspect of the invention the cap has a convex outer surface on the greater part of its surface, while this outer face is provided with a concave depression arranged substantially opposite the zone. articulation of the cap on the skirt.

La dépression formée sur la face externe du bouchon constitue une zone de réception de l'extrémité d'un doigt d'un utilisateur, ce qui permet d'exercer un effort efficace pour rabattre le bouchon, en limitant les risques que le doigt de l'utilisateur ne glisse par rapport à la surface externe du bouchon.The depression formed on the outer face of the plug is a receiving zone of the end of a finger of a user, which allows to exert an effective effort to fold the cap, limiting the risk that the finger of the user slips relative to the outer surface of the plug.

Selon un autre aspect avantageux de l'invention, l'état de surface de la dépression est différent de l'état de surface de la partie convexe de la face externe du bouchon. On peut, en particulier, prévoir que la dépression a une surface plus rugueuse que la partie convexe. Ainsi, le coefficient de frottement du doigt de l'utilisateur avec cette dépression est relativement important, ce qui limite encore les risques de glissement. En outre, la dépression se raccorde avantageusement à une face supérieure d'un nez faisant saillie radialement à partir du bord du bouchon, ce nez permettant d'exercer sur le bouchon un effort d'ouverture du dispositif.According to another advantageous aspect of the invention, the surface state of the depression is different from the surface state of the convex portion of the outer face of the plug. In particular, it can be provided that the depression has a rougher surface than the convex portion. Thus, the coefficient of friction of the user's finger with this depression is relatively high, which further limits the risk of slippage. In addition, the depression is advantageously connected to an upper face of a nose projecting radially from the edge of the cap, this nose to exert on the cap a force of opening of the device.

Le dispositif de bouchage 1 représenté sur les figures 1 à 6 est prévu pour être monté sur le col 2 d'une bouteille 3 dont seule la partie supérieure est visible sur les figures 3 à 6.The closure device 1 shown in Figures 1 to 6 is provided to be mounted on the neck 2 of a bottle 3, only the upper part is visible in Figures 3 to 6.

Le dispositif 1 comprend un bouchon 11 et une jupe 12 globalement symétriques par rapport à un axe central X-X' du dispositif 1.The device 1 comprises a plug 11 and a skirt 12 generally symmetrical with respect to a central axis X-X 'of the device 1.

Le dispositif 1 est monobloc et réalisé par moulage de matière plastique. Une bande déchirable 13 relie le bouchon 11 et la jupe 12 sur l'essentiel de la périphérie du dispositif 1 à l'exception d'une zone 14, plus particulièrement visible à la figure 2, dans laquelle le bouchon 11 est articulé sur la jupe 12.The device 1 is monobloc and made by molding plastic material. A tear strip 13 connects the plug 11 and the skirt 12 over most of the periphery of the device 1 except for a zone 14, more particularly visible in FIG. 2, in which the plug 11 is hinged to the skirt. 12.

La jupe 12 est pourvue d'une nervure interne 121 destinée à coopérer avec une collerette annulaire externe 21 du col 2 pour l'immobilisation du dispositif 1 sur le col 2.The skirt 12 is provided with an internal rib 121 intended to cooperate with an outer annular collar 21 of the neck 2 for the immobilization of the device 1 on the neck 2.

Deux lamelles élastiques 15 et 15' relient le bouchon 11 et la jupe 12, de part et d'autre d'une languette 122 s'étendant vers le haut à partir du bord supérieur.123 de la jupe 12.Two elastic strips 15 and 15 'connect the plug 11 and the skirt 12, on either side of a tongue 122 extending upwards from the upper edge of the skirt 12.

Dans la présente description, les adjectifs « supérieur » et « inférieur » sont définis en référence à un bouchon posé à plat sur une surface globalement horizontale dans la position des figures 1 et 2. Les parties supérieures du dispositif 1 sont orientées vers le haut sur les figures, alors que les parties inférieures sont orientées vers le bas.In the present description, the adjectives "upper" and "lower" are defined with reference to a plug lying flat on a surface generally. horizontal in the position of Figures 1 and 2. The upper parts of the device 1 are oriented upwards in the figures, while the lower parts are oriented downwards.

La face supérieure ou externe 111 du bouchon 11 est bombée, c'est-à-dire présente une convexité marquée, sur une partie principale 112 correspondant à la majeure partie de la face 111.The upper or outer face 111 of the plug 11 is curved, that is to say has a marked convexity, on a main portion 112 corresponding to most of the face 111.

Une dépression 113 est prévue dans cette face 111, à l'opposé de la zone 14, cette dépression 113 étant concave, c'est-à-dire formant un creux par rapport à la partie principale 112. Cette dépression 113 constitue une zone naturelle d'exercice d'un effort sur le bouchon 11.A depression 113 is provided in this face 111, opposite to the zone 14, the depression 113 being concave, that is to say forming a hollow relative to the main portion 112. This depression 113 constitutes a natural area exercising a force on the plug 11.

Lorsque le dispositif 1 est monté sur le col 2 de la bouteille 3 et lorsqu'on souhaite ouvrir cette bouteille, on exerce sur une poignée 131 de la bande 13 un effort F2 d'arrachement de la bande 13, ce qui permet de libérer le bord 114 du bouchon 11 de sa liaison avec la jupe 12 sur la plus grande partie de la périphérie du dispositif 1. Il est alors possible de faire basculer le bouchon 11 autour d'un axe géométrique A-A' globalement perpendiculaire à l'axe X-X' en exerçant sur un nez 115 du bouchon 11 un effort F3 adapté. Le nez 115 fait saillie radialement par rapport au bord 114 du bouchon 11 à l'opposé de la zone 14.When the device 1 is mounted on the neck 2 of the bottle 3 and when it is desired to open this bottle, it exerts on a handle 131 of the band 13 a force F 2 of tearing of the band 13, which allows to release the edge 114 of the plug 11 of its connection with the skirt 12 over most of the periphery of the device 1. It is then possible to tilt the plug 11 about a geometric axis AA 'generally perpendicular to the axis XX by exerting on a nose 115 of the plug 11 a suitable effort F 3 . The nose 115 protrudes radially from the edge 114 of the stopper 11 opposite zone 14.

Ceci permet de faire passer le bouchon de la configuration des figures 1 et 2 jusqu'à celle des figures 4 à 6, en passant par celle de la figure 3.This allows to pass the plug of the configuration of Figures 1 and 2 to that of Figures 4 to 6, through that of Figure 3.

Lorsqu'il convient de refermer le dispositif 1, il est possible d'exercer un effort F4 sur la dépression 113.When it is necessary to close the device 1, it is possible to exert a force F 4 on the depression 113.

Compte tenu de la forme de cette dépression, cet effort F4 peut être exercé avec un doigt d'une main dont les autres doigts sont disposés au niveau de la jupe 12. Ainsi, il est possible de fermer aisément le dispositif 1, c'est-à-dire de faire basculer le bouchon 11 pour le ramener dans sa position des figures 1 et 2.Given the shape of this depression, this effort F 4 can be exerted with a finger of a hand whose other fingers are arranged at the level of the skirt 12. Thus, it is possible to easily close the device 1, c ' is to say to tilt the cap 11 to bring it back to its position of Figures 1 and 2.

La dépression 113 est prévue plus rugueuse que la partie principale 112 de la face 111, afin que l'effort F4 puisse être exercé sans risque de glissement du doigt d'un utilisateur. Par exemple la surface 113 peut être grainée ou striée.The depression 113 is provided rougher than the main portion 112 of the face 111, so that the effort F 4 can be exercised without risk of sliding of a user's finger. For example, the surface 113 may be grained or streaked.

Par ailleurs, la face supérieure 1.16 du nez 115 prolonge la dépression 113, de sorte que la surface sur laquelle peut être exercé l'effort F4 est augmentée d'autant.On the other hand, the upper face 1.16 of the nose 115 extends the depression 113, so that the surface on which the force F 4 can be exerted is increased accordingly.

Le bouchon 11 est également pourvu d'une saillie 117 s'étendant sensiblement à l'opposé du nez 115 par rapport à l'axe X-X', c'est-à-dire dans la zone 14.The plug 11 is also provided with a projection 117 extending substantially opposite the nose 115 with respect to the axis X-X ', that is to say in the zone 14.

Au cours du pivotement du bouchon 11 autour de l'axe A-A', la saillie 117 vient reposer par l'extérieur contre la languette 122 sous l'effet d'un effort élastique F5 exercé par les lamelles 15 et 15'. Du fait de cet effort F5, la languette 122 est plaquée contre la surface radiale externe 22 du col 2, à proximité de son bord supérieur 23, cette surface 22 exerçant un effort de réaction F6 sur la saillie 117, la direction et l'intensité des efforts F5 et F6 étant telles qu'on obtient un blocage du bouchon 11 dans la position des figures 4 à 6.During the pivoting of the plug 11 about the axis A-A ', the projection 117 comes to rest from the outside against the tongue 122 under the effect of an elastic force F 5 exerted by the slats 15 and 15'. Due to this effort F 5 , the tongue 122 is pressed against the outer radial surface 22 of the neck 2, near its upper edge 23, this surface 22 exerting a reaction force F 6 on the projection 117, the direction and the the intensity of the forces F 5 and F 6 being such that a blockage of the plug 11 is obtained in the position of FIGS. 4 to 6.

Dans la position des figures 4 à 6, la languette 122 est comprimée entre la section 117 et le col 2. Cette languette 122 s'étend, à partir de la jupe 12, jusqu'au dessus de l'axe géométrique A-A' d'articulation du bouchon 11 sur la jupe 12.In the position of Figures 4 to 6, the tongue 122 is compressed between the section 117 and the neck 2. This tongue 122 extends from the skirt 12 to the top of the geometric axis AA 'd' articulation of the plug 11 on the skirt 12.

Dans cette position, on note que l'angle d'ouverture α du bouchon 11 est supérieur à 180°, de sorte que l'accès au col 2 est clairement dégagé, alors que même le bouchon 11 est pourvu d'une jupe interne 118. Ainsi, le bouchon 11 ne risque pas de gêner un utilisateur qui verse le contenu de la bouteille, quelle que soit l'orientation du bouchon 11 autour de l'axe X-X'. De plus, le bouchon 11 ne gêne pas une personne désirant boire directement au goulot de la bouteille 11.In this position, it is noted that the opening angle α of the plug 11 is greater than 180 °, so that the access to the neck 2 is clearly clear, while even the plug 11 is provided with an inner skirt 118 Thus, the plug 11 will not interfere with a user who pours the content of the bottle, regardless of the orientation of the cap 11 around the axis X-X '. In addition, the plug 11 does not interfere with a person wishing to drink directly at the neck of the bottle 11.

On note également que le dispositif de bouchage de l'invention présente l'avantage particulier de pouvoir être moulé dans la configuration des figures 1 et 2, c'est-à-dire en configuration fermée, configuration dans laquelle il peut être directement monté sur le col 2 de la bouteille 3. Un moulage en configuration fermée autorise une grande densité des empreintes dans le moule de fabrication.It is also noted that the closure device of the invention has the particular advantage of being moldable in the configuration of FIGS. 1 and 2, that is to say in a closed configuration, a configuration in which it can be directly mounted on the collar 2 of the bottle 3. A molding in closed configuration allows a high density of impressions in the manufacturing mold.

La section 117 du bouchon 11 ne fait pas saillie de façon trop importante par rapport au bord du bouchon, de sorte qu'elle ne gêne pas ses manipulations par des dispositifs automatisés en vue de sa mise en place sur la goulot 2. En outre, la section 117 ne risque pas de blesser un utilisateur.The section 117 of the plug 11 does not protrude too much with respect to the edge of the cap, so that it does not interfere with its manipulation by automated devices for its implementation on the neck 2. In addition, Section 117 is not likely to hurt a user.

Dans le second mode de réalisation de l'invention représenté aux figures 7 et 8, les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 500. Le dispositif 501 de ce mode de réalisation est prévu pour être monté sur le col 502 d'une bouteille 503. Un bouchon 511 est articulé sur une jupe 512 grâce à des lamelles élastiques 515 et 515' formées dans une zone d'articulation 514.In the second embodiment of the invention shown in FIGS. 7 and 8, elements similar to those of the first embodiment bear identical references increased by 500. The device 501 of this embodiment is intended to be mounted on the 502 of a bottle 503. A plug 511 is articulated on a skirt 512 by means of elastic strips 515 and 515 'formed in a hinge zone 514.

Des éléments en saillie 513 s'étendent à partir du bord supérieur 623 de la jupe 512 et sont reliés de façon sécable au bord inférieur 614 du bouchon 511.Projecting elements 513 extend from the upper edge 623 of the skirt 512 and are splittably connected to the lower edge 614 of the plug 511.

Comme précédemment, la surface externe 611 du bouchon 511 comprend une partie principale 612 dont les bords sont arrondis et dont le dessus est globalement plan. Cette partie 612 est donc convexe. Une dépression 613 est ménagée sur le bouchon 511 sensiblement à l'opposé de la zone 514. Cette dépression permet une transmission d'effort efficace lorsqu'il convient de refermer le bouchon, comme représenté par la flèche F4 à la figure 8.As before, the outer surface 611 of the plug 511 comprises a main portion 612 whose edges are rounded and whose top is generally flat. This part 612 is therefore convex. A depression 613 is formed on the plug 511 substantially opposite the zone 514. This depression allows effective transmission of effort when it is necessary to close the cap, as represented by the arrow F 4 in figure 8.

Une saillie 617 est prévue sur le bouchon 611 entre les lamelles 515 et 515', cette saillie venant en appui contre le bord supérieur 522 du col 502, comme représenté à la figure 8. Ceci permet d'immobiliser le bouchon 511 dans la position ouverte représentée sur cette figure, avec la conjonction d'efforts analogues aux efforts F5 et F6 mentionnés en référence au premier mode de réalisation.A protrusion 617 is provided on the plug 611 between the lamellae 515 and 515 ', this projection bearing against the upper edge 522 of the neck 502, as shown in FIG. 8. This makes it possible to immobilize the plug 511 in the open position shown in this figure, with the conjunction of efforts similar to the efforts F 5 and F 6 mentioned with reference to the first embodiment.

Comme représenté à la figure 9, où les éléments analogues à ceux du second mode de réalisation portent des références identiques, la forme de la section 617 peut être modifiée dans un troisième mode de réalisation, de telle sorte que, en configuration ouverte et bloquée, l'angle d'ouverture α' du bouchon 511 est supérieur à 180°.As shown in FIG. 9, where the elements similar to those of the second embodiment bear identical references, the shape of the section 617 can be modified in a third embodiment, so that, in the open and locked configuration, the opening angle α 'of the plug 511 is greater than 180 °.

Comme précédemment, la section 617 vient en appui contre le bord supérieur 522 du col 502, au dessus du bord supérieur 623 de la jupe 512.As previously, the section 617 bears against the upper edge 522 of the neck 502, above the upper edge 623 of the skirt 512.

Comme représenté à la figure .10, où les éléments analogues à ceux du premier mode de réalisation portent des références identiques augmentées de 1000, on peut prévoir, dans une zone d'articulation 1014 entre un bouchon 1011 et une jupe 1012, deux sections 1117 et 1117' s'étendant vers le bas à partir du bord inférieur 1114 du bouchon 1011 en direction de la jupe 1012, cette jupe étant destinée à être disposée autour du col 1002 d'une bouteille 1003.As shown in FIG. 10, where elements similar to those of the first embodiment have identical references increased by 1000, it is possible, in a hinge zone 1014 between a plug 1011 and a skirt 1012, to have two sections 1117. and 1117 'extending downwardly from the lower edge 1114 of the plug 1011 towards the skirt 1012, this skirt being intended to be arranged around the neck 1002 of a bottle 1003.

Une lamelle élastique 1015 relie le bouchon 1011 et la jupe 1012 et constitue une charnière d'articulation autour d'un axe A-A' globalement perpendiculaire à un axe de symétrie X-X' du goulot 1002 et du dispositif de bouchage 1001.An elastic strip 1015 connects the plug 1011 and the skirt 1012 and constitutes a hinge hinge about an axis A-A 'generally perpendicular to an axis of symmetry X-X' of the neck 1002 and the closure device 1001.

Comme précédemment, la face externe 1111 du bouchon 1011 comprend une partie principale convexe 1112 et une dépression concave 1113.As previously, the outer face 1111 of the plug 1011 comprises a convex main portion 1112 and a concave depression 1113.

En configuration ouverte du dispositif 1001, les sections en saillies 1117 et 1117' viennent respectivement en appui contre le bord supérieur du col 1002 de part et d'autre de la lamelle 1015. La géométrie des sections 1117 et 1117' peut être choisie, de telle sorte que l'angle d'ouverture du bouchon 1011 en position bloquée soit supérieur à 180°.In the open configuration of the device 1001, the projecting sections 1117 and 1117 'respectively bear against the upper edge of the neck 1002 on either side of the lamella 1015. The geometry of the sections 1117 and 1117' can be chosen from such that the opening angle of the plug 1011 in the locked position is greater than 180 °.

Comme représenté aux figures 11A à 11C, une autre articulation peut être envisagée dans laquelle des lamelles élastiques 815 et 815' relient une partie 811 d'un dispositif, qui peut correspondre à un bouchon, à une autre partie 812, qui peut correspondre à une jupe. La partie 812 comprend un plot central 8121 dont la surface supérieure 8122 est inclinée d'un angle β égal à environ 45° par rapport à un axe central Z-Z' du plot 8121.As shown in FIGS. 11A to 11C, another articulation may be envisaged in which elastic strips 815 and 815 'connect a part 811 of a device, which may correspond to a plug, to another part 812, which may correspond to a skirt. The portion 812 comprises a central stud 8121 whose upper surface 8122 is inclined at an angle β equal to about 45 ° with respect to a central axis Z-Z 'of the stud 8121.

Par ailleurs, la partie 811 est pourvue de tourillons 8111 lui permettant de pivoter autour d'un axe A-A' par rapport aux extrémités supérieures des lamelles 815 et 815'.Furthermore, the portion 811 is provided with pins 8111 allowing it to pivot about an axis A-A 'relative to the upper ends of the slats 815 and 815'.

Dans la position de la figure 11A, la surface inférieure 8112 de la partie 811 est inclinée d'un angle γ par rapport à l'axe Z-Z' qui est sensiblement égal à l'angle β.In the position of FIG. 11A, the lower surface 8112 of the portion 811 is inclined at an angle γ relative to the axis Z-Z 'which is substantially equal to the angle β.

Lorsqu'on fait tourner la partie 811 autour de l'axe A-A', les lamelles 815 et 815' ont tendance à être étirées, du fait de la différence de longueur des parties en contact 811 et 812, puis ces lamelles se contractent à nouveau en plaquant fermement une surface latérale 8113 de la partie 811 contre la surface 8122 de la partie 812, comme représenté à la figue 10C. Dans cette position, la partie 811 est maintenue en position rabattue par rapport à la partie 812, du fait de l'effort élastique dû aux lamelles 815 et 815'.When the part 811 is rotated around the axis A-A ', the lamellae 815 and 815' tend to be stretched, because of the difference in length of the parts in contact 811 and 812, then these lamellae contract again by firmly plating a side surface 8113 of the portion 811 against the surface 8122 of the portion 812, as shown in Fig. 10C. In this position, the portion 811 is held in the folded position relative to the portion 812, due to the elastic force due to the slats 815 and 815 '.

Une telle structure pourrait être utilisée, comme charnière bi-stable, pour le bouchon des trois dispositifs de bouchage décrits ci-dessus.Such a structure could be used as a bi-stable hinge for the plug of the three plugging devices described above.

Ce mode de réalisation présente l'avantage particulier que la charnière ainsi constituée est stable dans les deux positions représentées respectivement aux figures 11A et 11C.This embodiment has the particular advantage that the hinge thus formed is stable in the two positions shown respectively in Figures 11A and 11C.

Comme représenté aux figures 12A à 12C, il est possible de modifier la charnière représentée aux figures 11A à 11C pour que son angle d'ouverture α'' soit supérieur à 180°. Dans ce cas, la partie 811 est pourvue d'une partie 8114 en forme de tronçon de cylindre centré sur l'axe A-A' de rotation défini par les tourillons 8111 et par les parties supérieures des lamelles 815 et 815'.As shown in FIGS. 12A to 12C, it is possible to modify the hinge shown in FIGS. 11A to 11C so that its opening angle α '' is greater than 180 °. In this case, the portion 811 is provided with a portion 8114 in the form of a cylinder section centered on the axis A-A 'of rotation defined by the trunnions 8111 and the upper parts of the slats 815 and 815'.

Lors du mouvement d'ouverture de la charnière ainsi constituée, la surface cylindrique de la partie 8114 glisse contre la surface supérieure 8122 du plot 8121 de la partie fixe 812, ce qui permet d'obtenir un mouvement d'ouverture de grande amplitude angulaire α".During the opening movement of the hinge thus formed, the cylindrical surface of the portion 8114 slides against the upper surface 8122 of the stud 8121 of the fixed part 812, which makes it possible to obtain an opening movement of large angular amplitude α ".

Dans la configuration de la figure 12C, la charnière est stable grâce à l'appui surfacique de la surface latérale 8113 de la partie 811 sur la surface 8122 du plot 8121.In the configuration of FIG. 12C, the hinge is stable thanks to the surface bearing of the lateral surface 8113 of the part 811 on the surface 8122 of the pad 8121.
