Description

Bague d'espacement destinée à être positionnée entre un réceptacle et un bouchon et ensemble dudit réceptacle et de ladite bague  Spacer ring for positioning between a receptacle and a stopper and assembly of said receptacle and said ring
La présente invention concerne une bague d'espacement destinée à être positionnée entre un réceptacle, notamment un tube, en particulier un tube souple de produit cosmétique, et un bouchon dudit tube. Elle concerne aussi un ensemble formé d'un tel réceptacle et d'une telle bague. The present invention relates to a spacer ring intended to be positioned between a receptacle, in particular a tube, in particular a flexible tube of cosmetic product, and a plug of said tube. It also relates to an assembly formed of such a receptacle and such a ring.
On connaît des tubes munis d'un opercule associés à un bouchon perforateur comprenant un poinçon adapté pour perforer ledit opercule à la première utilisation du tube. Tubes provided with a lid associated with a perforating plug comprising a punch adapted to perforate said lid at the first use of the tube.
L'opercule permet de conserver le produit contenu dans le tube de manière hermétique pendant son stockage préalablement à sa première utilisation, ce qui représente une part très importante de la durée de vie globale du tube. The operculum makes it possible to preserve the product contained in the tube hermetically during its storage prior to its first use, which represents a very important part of the overall lifespan of the tube.
De nombreuses solutions ont été présentées en ce sens. On connaît notamment des bouchons comprenant un poinçon, adapté pour découper et/ou percer l'opercule, lesdits bouchons étant configurés pour être positionnés sur un goulot du tube, dans une position d'attente laissant l'opercule intact, et dans une position d'utilisation dans laquelle l'opercule a été découpé et/ou percé par ledit poinçon. Many solutions have been presented to this effect. Known plugs including a punch adapted to cut and / or pierce the lid, said plugs being configured to be positioned on a neck of the tube, in a waiting position leaving the lid intact, and in a position d use in which the lid has been cut and / or pierced by said punch.
Le passage d'une position à l'autre s'effectue, par exemple, en enlevant la bague d'espacement disposée sur le tube pour maintenir le bouchon en position d'attente. Lors de la première utilisation, l'utilisateur retire le bouchon puis la bague. Il peut alors repositionner le bouchon qui, en l'absence de la bague, s'enfonce suffisamment dans le tube pour que le poinçon perce l'opercule. The passage from one position to another is effected, for example, by removing the spacer ring disposed on the tube to hold the cap in the waiting position. During the first use, the user removes the cap and the ring. He can then reposition the cap which, in the absence of the ring, sinks sufficiently into the tube so that the punch pierces the lid.
Pour permettre une meilleure protection du produit, il a déjà été proposé de disposer les opercules à une extrémité du goulot débouchant dans le volume intérieur du tube, c'est-à-dire à l'extrémité du goulot opposée à celle débouchant vers l'extérieur. To allow a better protection of the product, it has already been proposed to arrange the lids at one end of the neck opening into the interior volume of the tube, that is to say at the end of the neck opposite to that leading to the outside.
Une telle configuration nécessite la réalisation de poinçons présentant une extension longitudinale suffisante pour atteindre l'opercule de manière à le découper lors de la première utilisation et le poinçon doit pénétrer à l'intérieur du goulot, y compris en position d'attente. Such a configuration requires the production of punches having a longitudinal extension sufficient to reach the lid so as to cut when first used and the punch must penetrate inside the neck, including in the waiting position.
A l'inverse, il est essentiel que le poinçon n'endommage pas l'opercule tant que le bouchon est en position d'attente, avant la première utilisation. Le bon positionnement de la bague d'espacement joue un rôle capital en ce sens et il existe un besoin d'amélioration des solutions connues à ce jour dans ce domaine. Conversely, it is essential that the punch does not damage the lid as long as the cap is in the waiting position, before the first use. The proper positioning of the spacing ring plays a vital role in this sense and there is a need to improve the solutions known to date in this field.
L'invention propose à cet effet une bague d'espacement destinée à être positionnée entre un réceptacle, notamment, un tube, en particulier un tube souple de produit cosmétique, et un bouchon dudit réceptacle, ladite bague comprenant des nervures de centrage sur un goulot dudit réceptacle. The invention proposes for this purpose a spacer ring intended to be positioned between a receptacle, in particular a tube, in particular a flexible tube of cosmetic product, and a plug of said receptacle, said ring comprising centering ribs on a neck. said receptacle.
Grâce à l'effet de centrage obtenu par l'intermédiaire des nervures de la bague conforme à l'invention, il est possible d'obtenir un meilleur positionnement de la bague sur le réceptacle et, par suite, une meilleure maîtrise de l'espacement entre le bouchon et le tube coopérant avec la bague. On limite de la sorte les risques de perçage non désiré d'un opercule dont le réceptacle serait muni.. Selon différentes caractéristiques de l'invention qui pourront être prise ensemble ou séparément : Thanks to the centering effect obtained through the ribs of the ring according to the invention, it is possible to obtain better positioning of the ring on the receptacle and, consequently, better control of the spacing between the plug and the tube cooperating with the ring.

Ladite tête de tube 2 est destinée à être liée à une jupe, non-illustrée, du tube, typiquement en surmoulant la tête de tube 2 sur la jupe, ou par exemple par soudage ou collage en assemblant la jupe sur la tête de tube 2 formée préalablement, notamment par injection ou par injection compression, ou par toutes autres techniques. En variante, l'invention pourra ainsi concerner un ensemble comprenant une tête de tube plutôt qu'un tube complet. The invention relates to an assembly comprising a receptacle, in particular a tube, in particular a tube for a cosmetic product, for example a flexible tube. By this we mean a tube whose body can be deformed, by resuming its original shape or not. Said assembly here also comprises a plug of the receptacle, in particular of said tube and / or of said tube head. In Figure 1, only a head 2 of said tube is shown. Said tube head 2 is intended to be linked to a skirt, not shown, of the tube, typically by overmolding the tube head 2 on the skirt, or for example by welding or gluing by assembling the skirt on the tube head 2 formed beforehand, in particular by injection or compression injection, or by any other technique. In variant, the invention may thus relate to an assembly comprising a tube head rather than a complete tube.
Ledit réceptacle, en particulier ladite tête de tube 2, comprend un goulot 3, définissant un axe longitudinal Z-Z et débouchant d'une part vers l'extérieur et d'autre part dans un volume intérieur 4 du réceptacle. Le goulot 3 comprend, par exemple, un filetage 6 sur sa périphérie externe, adapté pour permettre de visser le bouchon 1 sur le goulot 3. Ledit réceptacle, en particulier ladite tête de tube 2, comprend en outre un insert 8 plein formant un opercule obturant l'extrémité du goulot 3 tournée vers le volume intérieur 4. Autrement dit, ledit opercule ferme ledit volume intérieur 4. Ledit insert 8 est, par exemple, en contact, notamment en appui, contre une paroi intérieure 1 1 dudit réceptacle. L'insert 8 comprend, par exemple, une section périphérique 10 et une section centrale 12, définissant ledit opercule, dont le diamètre correspond au diamètre interne du goulot 3. Ledit insert 8 est typiquement en forme de disque. Alternativement, sa section périphérique 10 pourra être légèrement tronconique ou comprendre une zone plane, entourant le goulot et, autour de ladite zone plane, une ou plusieurs zones légèrement tronconiques successives jusqu'à sa périphérie qui pourra être formée, par exemple, d'un bord plié 13. Said receptacle, in particular said tube head 2, comprises a neck 3, defining a longitudinal axis Z-Z and opening on the one hand outwards and on the other hand in an interior volume 4 of the receptacle. The neck 3 comprises, for example, a thread 6 on its outer periphery, adapted to allow screwing the cap 1 on the neck 3. Said receptacle, in particular said tube head 2, further comprises a solid insert 8 forming a cap closing the end of the neck 3 turned towards the inner volume 4. In other words, said lid closes said interior volume 4. Said insert 8 is, for example, in contact, in particular in abutment, against an inner wall 1 1 of said receptacle. The insert 8 comprises, for example, a peripheral section 10 and a central section 12, defining said cap, the diameter of which corresponds to the internal diameter of the neck 3. Said insert 8 is typically disk-shaped. Alternatively, its peripheral section 10 may be slightly frustoconical or comprise a planar zone surrounding the neck and, around said planar zone, one or more slightly frustoconical successive zones to its periphery which may be formed, for example, of a folded edge 13.
Ledit insert 8 est préférentiellement un insert multicouche comprenant une couche barrière, par exemple formée d'EVOH ou métallique, notamment aluminium, revêtue sur chacune de ses faces d'une ou de couches de protection, notamment en matériaux polymérisés. Said insert 8 is preferably a multilayer insert comprising a barrier layer, for example formed of EVOH or metal, in particular aluminum, coated on each of its faces with one or more protective layers, in particular of polymerized materials.
Ici, ledit goulot 3 et ledit insert 4 sont prévus au niveau de ladite tête de tube 2. Cette dernière pourra en outre comprendre, par exemple, une épaule 20, issue dudit goulot 3. La matière de la tête de tube 2 entoure au moins partiellement ledit bord plié 13 de l'insert 8 afin de le protéger, en particulier de protéger la couche métallique dudit insert 8. Here, said neck 3 and said insert 4 are provided at said tube head 2. The latter may further comprise, for example, a shoulder 20, issuing from said neck 3. The material of the tube head 2 surrounds at least partially said folded edge 13 of the insert 8 to protect it, in particular to protect the metal layer of said insert 8.
Comme visible aux figures 2 et 3, ledit bouchon 1 est ici adapté pour être vissé sur ledit goulot 3. Plus précisément, ledit bouchon 1 pourra comprendre un taraudage 16 interne adapté pour coopérer avec le filetage 6 du goulot 3. Ledit bouchon présente une direction longitudinale, correspondant à l'axe longitudinal Z-Z du goulot 3 lorsque le bouchon 1 est vissé sur le goulot 3. As can be seen in FIGS. 2 and 3, said cap 1 is here adapted to be screwed onto said neck 3. More precisely, said stopper 1 may comprise an internal tapping 16 adapted to cooperate with the thread 6 of the neck 3. Said stopper has a longitudinal direction, corresponding to the longitudinal axis ZZ of the neck 3 when the cap 1 is screwed onto the neck 3.
Ledit bouchon 1 comprend une paroi périphérique 15 adaptée pour la fixation du bouchon au réceptacle munie intérieurement dudit taraudage 16. Ladite paroi périphérique 15 pourra être munie de pans plans, situés extérieurement, afin de faciliter la manipulation du bouchon 1 . Said stopper 1 comprises a peripheral wall 15 adapted for fixing the stopper to the receptacle internally provided with said tapping 16. Said peripheral wall 15 may be provided with flat panels, situated on the outside, in order to facilitate the handling of the stopper 1.
Ledit bouchon 1 comprend un poinçon 14, adapté pour découper et/ou percer l'opercule. Ledit bouchon 1 est configuré pour être positionné sur ledit goulot 3, dans une position d'attente dans laquelle le poinçon 14 est au moins en partie dans le goulot 3, en laissant l'opercule intact. Said cap 1 comprises a punch 14, adapted to cut and / or pierce the lid. Said cap 1 is configured to be positioned on said neck 3, in a waiting position in which the punch 14 is at least partly in the neck 3, leaving the lid intact.
Comme illustrés aux figures 4 et 5, ledit ensemble comprend une bague d'espacement 22, amovible, destinée à être positionnée entre le réceptacle, notamment, le tube, en particulier ladite tête de tube 2 et le bouchon 1 dudit réceptacle. Plus précisément, telle qu'illustrée, la bague 22 est destinée à être disposée en appui sur un corps du réceptacle, ici sur l'épaule 20 de ladite tête de tube 2, autour du goulot 3, en position d'attente. Elle maintient ainsi un espacement entre le bouchon 1 et l'épaule 20 lorsque le bouchon 1 est vissé sur le goulot 3 en attendant la première utilisation. Le poinçon 14 s'étend alors à l'intérieur du goulot 3, à une distance non nulle de l'insert 8, préservant ainsi l'opercule de toute découpe ou perforation. Selon l'invention, ladite bague d'espacement 22 comprend une pluralité de nervures 70 adaptées pour permettre son centrage autour du goulot 3. Ladite bague 22 est indépendante dudit bouchon 1 de sorte que ledit bouchon 1 peut être retiré dudit réceptacle sans que ladite bague 22 le soit. Ladite bague d'espacement 22 est annulaire, par exemple de section circulaire. As illustrated in Figures 4 and 5, said assembly comprises a spacer ring 22, removable, intended to be positioned between the receptacle, in particular, the tube, in particular said tube head 2 and the cap 1 of said receptacle. More precisely, as illustrated, the ring 22 is intended to be placed in abutment on a body of the receptacle, here on the shoulder 20 of said tube head 2, around the neck 3, in the waiting position. It thus maintains a spacing between the cap 1 and the shoulder 20 when the cap 1 is screwed onto the neck 3 while waiting for the first use. The punch 14 then extends inside the neck 3, at a non-zero distance from the insert 8, thus preserving the lid from any cutting or perforation. According to the invention, said spacer ring 22 comprises a plurality of ribs 70 adapted to allow its centering around the neck 3. Said ring 22 is independent of said cap 1 so that said cap 1 can be removed from said receptacle without said ring 22 be it. Said spacer ring 22 is annular, for example of circular section.
Avantageusement, lesdites nervures 70 sont orientées radialement. Lesdites nervures 70 sont, par exemple, disposées symétriquement entre elles de manière à ce que la bague 22 puisse être positionnée angulairement de façon indifférenciée sur ledit goulot 3. Ainsi, il n'est pas nécessaire d'orienter angulairement la bague 22 lors de son montage sur le réceptacle. Lesdites nervures 22 présentent ici un bord interne libre présentant une portion centrale 72 d'extension radiale interne maximum. Ledit bord interne libre comprend en outre un ou des épaulements 74 au voisinage de ladite portion centrale 72. Ledit bord interne libre présente encore une ou des extrémités longitudinales 76 chanfreinées. Advantageously, said ribs 70 are oriented radially. Said ribs 70 are, for example, arranged symmetrically with each other so that the ring 22 can be positioned angularly undifferentiated on said neck 3. Thus, it is not necessary to angularly orient the ring 22 during its operation. mounting on the receptacle. Said ribs 22 here have a free inner edge having a central portion 72 of maximum internal radial extension. Said free internal edge further comprises one or more shoulders 74 in the vicinity of said central portion 72. Said free inner edge also has one or more longitudinal ends 76 chamfered.
Avantageusement, lesdites nervures 70 sont symétriques par rapport un plan transversal médian de la bague. Ainsi, ladite portion centrale 72 s'étend de part et d'autre dudit plan médian, ladite portion centrale 72 étant prolongée de part et d'autre par l'un desdits épaulements 74, lesdits épaulements 74 étant prolongés à leur tour de part et d'autre par l'une desdites extrémités longitudinales chanfreinées 76. Ledit bord libre présente de la sorte une configuration en paliers, les paliers étant reliés entre eux par des pans obliques, notamment à 45°. Une telle configuration symétrique permet de monter la bague 22 sur le réceptacle indépendamment de son orientation longitudinale. Advantageously, said ribs 70 are symmetrical with respect to a median transverse plane of the ring. Thus, said central portion 72 extends on either side of said median plane, said central portion 72 being extended on either side by one of said shoulders 74, said shoulders 74 being extended in turn and else by one of said chamfered longitudinal ends 76. Said free edge thus presents a configuration in steps, the bearings being interconnected by oblique faces, in particular at 45 °. Such a symmetrical configuration makes it possible to mount the ring 22 on the receptacle independently of its longitudinal orientation.
Ladite bague 22 est formée, par exemple, par injection. Elle comprend ici une surépaisseur 78 annulaire interne, servant à maintenir la bague lors de son démoulage. Said ring 22 is formed, for example, by injection. It includes here an inner ring thickness 78, serving to maintain the ring during its demolding.
Ledit bouchon 1 est en outre adapté pour être positionné sur ledit goulot 3, dans une position d'utilisation dans laquelle l'opercule a été découpé et/ou percé par ledit poinçon 14.. Lors de la première utilisation, l'utilisateur dévisse le bouchon 1 du goulot 3, puis retire la bague 22 d'espacement, et revisse le bouchon 1 sur le goulot 3 jusqu'à ce qu'il vienne en butée contre le goulot 3 ou contre l'épaule 20. Le poinçon 14 a alors réalisé une découpe ou une perforation de l'insert 8, et plus précisément de sa section centrale 12 formant l'opercule de la tête de tube 2. Said cap 1 is further adapted to be positioned on said neck 3, in a position of use in which the lid has been cut and / or pierced by said punch 14. During the first use, the user unscrews the cap 1 of the neck 3, then removes the spacer ring 22, and screw the cap 1 on the neck 3 until it abuts against the neck 3 or against the shoulder 20. The punch 14 then made a cut or a perforation of the insert 8, and more precisely of its central section 12 forming the lid of the tube head 2.
Si l'on se reporte de nouveau aux figures 2 et 3, on constate que le bouchon 1 comprend une paroi 17, dite supérieure, fermant le poinçon à l'une des extrémités longitudinales dudit poinçon. La paroi 17 est dite supérieure car en utilisation verticale du réceptacle, bouchon en haut, elle formera la paroi supérieure du bouchon. Des utilisations selon toute autre orientation sont cependant possibles sans sortir du cadre de l'invention. Ladite paroi supérieure 17 relie le poinçon à la paroi périphérique 15. Ici, ladite paroi supérieure 17 relie un bord, dit supérieur, de la paroi périphérique 15 et un bord, dit supérieur, du poinçon 14. Referring again to Figures 2 and 3, it is found that the plug 1 comprises a wall 17, said upper, closing the punch at one of the longitudinal ends of said punch. The wall 17 is said to be upper because in vertical use of the receptacle, cap at the top, it will form the upper wall of the cap. Uses in any other orientation are however possible without departing from the scope of the invention. Said upper wall 17 connects the punch to the Peripheral wall 15. Here, said upper wall 17 connects an edge, said upper, of the peripheral wall 15 and an edge, said upper, of the punch 14.
Ledit bouchon 1 comprend en outre un jonc d'étanchéité 50 au niveau d'une liaison entre le poinçon 14 et la paroi périphérique 15. Une telle configuration permet d'obtenir un bon niveau d'étanchéité, en cas de fermeture du réceptacle après première utilisation, par un effet d'arcboutement du jonc contre la liaison, favorisant la compression du jonc plutôt qu'une simple déformation. Avantageusement, ladite paroi supérieure 17 est concave. De la sorte, si le réceptacle est posé tête en bas sur un support qui présente de légères aspérités, la forme concave permettra aux aspérités de ne pas être en contact avec le bouchon. Le réceptacle peut donc être posé verticalement sur le support car le bouchon repose sur celui-ci de façon plane, par un bord périphérique 60 de la paroi supérieure 17. En effet, la surface du bord périphérique 60 étant limitée, les risques sont diminués qu'elle soit en contact avec le support à un endroit où des aspérités sont présentes. Said cap 1 further comprises a sealing ring 50 at a connection between the punch 14 and the peripheral wall 15. Such a configuration makes it possible to obtain a good level of tightness, in case of closure of the receptacle after first use, by an arcboutement effect of the ring against the binding, favoring the compression of the ring rather than a simple deformation. Advantageously, said upper wall 17 is concave. In this way, if the receptacle is placed upside down on a support which has slight asperities, the concave shape will allow the asperities not to be in contact with the plug. The receptacle can therefore be placed vertically on the support because the cap rests on it flatly, by a peripheral edge 60 of the upper wall 17. Indeed, the surface of the peripheral edge 60 being limited, the risks are reduced that it is in contact with the support at a place where asperities are present.
Ladite paroi supérieure 17 présente localement un fond plat, notamment au droit du poinçon 14. Ledit fond plat pourra présenter un point 62 d'injection du bouchon. Said upper wall 17 locally has a flat bottom, in particular at the right of the punch 14. Said flat bottom may have a point 62 of injection plug.
Le jonc 50 est formé, par exemple, d'une surépaisseur de matière d'une base 52 du poinçon 14. Ladite surépaisseur de matière comprend ici une base 54 d'épaisseur décroissante, formant une rampe inclinée, une partie intermédiaire 56 d'épaisseur constante, formant une partie annulaire, et une partie d'extrémité 58 chanfreinée. The ring 50 is formed, for example, of an extra thickness of material of a base 52 of the punch 14. Said thickness of material here comprises a base 54 of decreasing thickness, forming an inclined ramp, an intermediate portion 56 of thickness constant, forming an annular portion, and a chamfered end portion 58.
Avantageusement, ledit poinçon 14 comprend un corps 30 en forme de fut configuré pour découper et/ou percer ledit opercule. Ledit fut présente sensiblement la forme d'un cylindre, creux. Par « sensiblement la forme d'un cylindre », on comprend, notamment, que ledit corps pourra présenter une forme très légèrement tronconique pour les besoins du démoulage, c'est-à-dire avec un angle au sommet inférieur à 2, voire 1 °. Autrement dit, le poinçon 14 présente une section transversale sensiblement annulaire, de révolution. L'épaisseur de paroi dudit poinçon 14 pourra être comprise entre 10 et 20% de son diamètre extérieur. Ledit corps 30 en forme de fut pourra s'étendre tout le long dudit poinçon 14. Ledit bouchon 1 est formée, par exemple, par injection, notamment de matière plastique. Ledit poinçon 14 est avantageusement configuré de façon que la découpe de l'opercule soit partielle, de manière à ce que la ou les portions de l'opercule ayant été découpées demeurent liées au reste de l'insert 8, en position d'utilisation, prévenant ainsi tout mélange du matériau formant l'insert 8 avec un produit contenu dans le réceptacle associé. Advantageously, said punch 14 comprises a body 30 shaped to be configured to cut and / or pierce said lid. Said was substantially the shape of a hollow cylinder. By "substantially the shape of a cylinder", it is understood, in particular, that said body may have a very slightly frustoconical shape for demoulding purposes, that is to say with an apex angle of less than 2, or even 1 °. In other words, the punch 14 has a substantially annular cross section, of revolution. The wall thickness of said punch 14 may be between 10 and 20% of its outer diameter. Said body 30 in the form of fut may extend all along said punch 14. Said plug 1 is formed, for example, by injection, in particular of plastic. Said punch 14 is advantageously configured so that the cutout of the lid is partial, so that the portion or portions of the lid having been cut remain connected to the remainder of the insert 8, in the position of use, thus preventing any mixing of the material forming the insert 8 with a product contained in the associated receptacle.
A titre d'exemple, en considérant qu'une découpe complète est une découpe à 360° de l'opercule, c'est-à-dire une découpe circulaire réalisée par rotation du bouchon 1 , on réalise avantageusement une découpe laissant un lien suffisant pour assurer la cohésion entre la section centrale 12 ayant été découpée, et la section périphérique 10. By way of example, considering that a complete cut is a 360 ° cut of the lid, that is to say a circular cut made by rotation of the cap 1, advantageously a cut is made leaving a sufficient link to ensure cohesion between the central section 12 having been cut, and the peripheral section 10.
Ledit fut présente une extrémité distale 32 avantageusement munie de moyens de découpe tels que des dents 40. Ledit fut est avantageusement configuré pour pénétrer dans ledit volume intérieur 4, en position d'utilisation, d'une distance supérieure à la distance nécessaire pour atteindre une déformation de l'insert 8 allant au-delà des capacités de déformation élastique dudit insert 8. Si l'on se reporte de nouveau à la figure 1 , on constate que ledit goulot 3 présente une base 80 destinée à coopérer avec un bord distal 82 du bouchon (figure 2), en position fermée du bouchon 1 , c'est-à-dire, après première utilisation, lorsque l'on referme le réceptacle avec le bouchon 1 , la bague 22 n'étant plus en place. Ici, la base 80 du goulot 3 se trouve au niveau d'une jonction entre le goulot 3 et l'épaule 20. Ladite base 80 présente, par exemple, une configuration tronconique. Said has a distal end 32 advantageously provided with cutting means such as teeth 40. Said was advantageously configured to penetrate into said interior volume 4, in the use position, a distance greater than the distance necessary to reach a desired distance. deformation of the insert 8 going beyond the elastic deformation capacity of said insert 8. Referring back to FIG. 1, it can be seen that said neck 3 has a base 80 intended to cooperate with a distal edge 82 the plug (Figure 2), in the closed position of the plug 1, that is to say, after first use, when the receptacle is closed with the cap 1, the ring 22 is no longer in place. Here, the base 80 of the neck 3 is at a junction between the neck 3 and the shoulder 20. Said base 80 has, for example, a frustoconical configuration.
Ledit bord distal 82 du bouchon présente au moins localement une configuration tronconique pour venir en contact avec ladite base du goulot en position fermée du bouchon. Il s'agit, par exemple, de surépaisseur interne 84 . On évite de la sorte une déformation non maîtrisée du bouchon 1 lors d'un vissage trop fort sur le goulot 3. Avantageusement, lesdites nervures 70 pourront aussi être en contact de ladite base 80 du goulot, notamment par l'une de ses extrémités 76 chanfreinées. On améliore de la sorte encore le centrage de la bague 22 sur le goulot 3. Said distal edge 82 of the plug has at least locally a frustoconical configuration to come into contact with said base of the neck in the closed position of the cap. This is, for example, internal extra thickness 84. In this way, uncontrolled deformation of the plug 1 is avoided when the neck 3 is screwed too hard. Advantageously, said ribs 70 may also be in contact with said base 80 of the neck, in particular by one of its chamfered ends 76. In this way, the centering of the ring 22 on the neck 3 is further improved.
