Description

La présente invention concerne le domaine des bouchons pour réceptacle.The present invention relates to the field of plugs for receptacles.

Classiquement, les bouchons sont fixés sur l'ouverture d'un réceptacle, tel qu'un goulot, par vissage. Le bouchon et le goulot sont alors pourvus de filets de vissage complémentaires coopérant ensemble. Lorsque l'utilisateur souhaite fermer ou ouvrir le réceptacle, il effectue un mouvement de vissage ou de dévissage dans un sens ou dans l'autre et, après plusieurs tours, soit le réceptacle est fermé, soit il est ouvert.Conventionally, the caps are fixed on the opening of a receptacle, such as a neck, by screwing. The cap and the neck are then provided with complementary screw threads cooperating together. When the user wishes to close or open the receptacle, it performs a screwing or unscrewing movement in one direction or the other and, after several turns, either the receptacle is closed, or it is open.

L'obtention de bouchons avec un filet de vissage présente cependant des inconvénients, notamment de démoulage du bouchon.Obtaining plugs with a screw thread, however, has disadvantages, in particular demolding the plug.

Il existe donc un besoin d'un bouchon dont le moulage soit facilité.There is therefore a need for a plug whose molding is facilitated.

A cet effet, la présente invention propose un bouchon configuré pour la fermeture d'un réceptacle comprenant un goulot. Ledit bouchon comprend :

  • au moins un élément en saillie configuré pour coopérer avec une rainure située sur ledit goulot de manière à ce que le bouchon passe d'une première position, notamment d'ouverture, à une seconde position, notamment de fermeture,
  • au moins une ouverture située sur une paroi supérieure dudit bouchon, la ou les dites ouvertures étant au droit des éléments en saillie dudit bouchon,
  • un élément d'étanchéité configuré pour conférer une étanchéité entre le bouchon et le goulot, ledit élément d'étanchéité étant radialement décalé par rapport audit élément en saillie.
For this purpose, the present invention provides a plug configured for closing a receptacle comprising a neck. Said stopper comprises:
  • at least one projecting element configured to cooperate with a groove situated on said neck so that the stopper passes from a first position, in particular an opening position, to a second position, in particular a closing position,
  • at least one opening located on an upper wall of said plug, the said opening or openings being at right angles to the elements projecting from said plug,
  • a sealing member configured to provide a seal between the cap and the neck, said sealing member being radially offset from said projecting member.

Autrement dit, le bouchon selon l'invention est exempte de filet de vissage. Pour permettre, cependant, l'ouverture ou la fermeture du réceptacle, l'invention prévoit moins un élément en saillie qui coopère avec une rainure située sur le goulot du réceptacle.In other words, the plug according to the invention is free of screw thread. To allow, however, the opening or closing of the receptacle, the invention provides less a protruding element which cooperates with a groove on the neck of the receptacle.

Contrairement aux filets des bouchons de l'état de l'art, le ou les éléments en saillie du bouchon selon l'invention vont pouvoir être obtenus par moulage par-dessus et par-dessous. Autrement dit, une partie du moule portant l'empreinte d'une première partie du bouchon vient par le haut et une autre partie portant l'empreinte du reste du bouchon vient par le bas. Pour ce type de moulage, le bouchon présente au moins une ouverture sur sa paroi supérieure au droit des éléments en saillie. L'étanchéité avec le réceptacle et alors assurée malgré les ouvertures, par l'élément d'étanchéité positionné de façon judicieuse.Unlike the nets plugs of the state of the art, the element or elements projecting from the cap according to the invention will be able to be obtained by molding over and under. In other words, a portion of the mold bearing the imprint of a first portion of the stopper comes from above and another part bearing the impression of the rest of the stopper comes from below. For this type of molding, the plug has at least one opening on its upper wall to the right of the projecting elements. Sealing with the receptacle and then ensured despite the openings, by the sealing element positioned judiciously.

On entend par bouchon un objet permettant l'obturation étanche d'un réceptacle, notamment d'une ouverture de sortie d'un produit, de manière réversible. Un bouchon selon l'invention peut ainsi passer d'une position d'ouverture à une position de fermeture et inversement, principalement par un mouvement de vissage ou équivalent. La présente invention n'inclut pas les ensembles de fermeture, telle qu'une capsule service à charnière, fixés sur ouverture de manière définitive et comprenant un orifice de passage pour la sortie du produit et une coiffe rabattable permettant d'obturer ledit orifice.Plug means an object for sealing a receptacle, in particular an outlet opening of a product, in a reversible manner. A plug according to the invention can thus move from an open position to a closed position and vice versa, mainly by a screwing movement or the like. The present invention does not include closure assemblies, such as a hinged service capsule, permanently fixed on opening and comprising a passage opening for the outlet of the product and a folding cap for closing said orifice.

Sur l'ensemble des figures, les éléments en commun sont repérés par des références numériques identiques.In all the figures, the elements in common are identified by identical reference numerals.

Comme illustré dans les différentes figures, l'invention concerne un bouchon 1 configuré pour la fermeture d'un réceptacle comprenant un goulot 3. Ledit bouchon 1 est ainsi conçu pour venir se fixer sur ledit goulot 3 pour fermer ledit réceptacle et former un ensemble comprenant le goulot 3 et ledit bouchon 1.As illustrated in the various figures, the invention relates to a stopper 1 configured for closing a receptacle comprising a neck 3. Said cap 1 is thus designed to be fixed on said neck 3 to close said receptacle and form an assembly comprising the neck 3 and said plug 1.

Dans les exemples illustrés ici, le réceptacle est un tube 5 comprenant une tête de tube 7 munit dudit goulot 3, définissant un axe longitudinal Z-Z, et d'une épaule 9.In the examples illustrated here, the receptacle is a tube 5 comprising a tube head 7 provided with said neck 3, defining a longitudinal axis Z-Z, and a shoulder 9.

De manière général, ledit bouchon 1 comprend une paroi périphérique 11 et une paroi supérieure 13. On définit une direction longitudinale du bouchon 1, correspondant à l'axe longitudinal Z-Z du goulot 3 lorsque le bouchon 1 est fixé sur le goulot 3.In general, said stopper 1 comprises a peripheral wall 11 and an upper wall 13. A longitudinal direction of the stopper 1, corresponding to the longitudinal axis Z-Z of the neck 3, is defined when the stopper 1 is fixed on the neck 3.

La surface externe de ladite paroi périphérique 11 pourra être munie de stries 11 a longitudinales afin de faciliter la manipulation du bouchon 1.The outer surface of said peripheral wall 11 may be provided with longitudinal ridges 11a to facilitate the manipulation of the stopper 1.

Selon l'invention, le bouchon, en particulier la surface interne de sa paroi périphérique 11 est exempte de filet de vissage. En revanche, au moins un élément en saillie 15 est situé sur cette surface interne. Le ou lesdits éléments en saillie 15 sont configurés pour coopérer avec une rainure 17 de guidage s'étendant sur une surface externe dudit goulot 3 de manière à ce que le bouchon 1 passe d'une position d'ouverture à une position de fermeture et inversement.According to the invention, the plug, in particular the inner surface of its peripheral wall 11 is free of screw thread. On the other hand, at least one projecting element 15 is located on this inner surface. The one or more projecting elements 15 are configured to cooperate with a guide groove 17 extending on an external surface of said neck 3 so that the stopper 1 moves from an open position to a closed position and vice versa. .

Dans le mode de réalisation représenté aux figures 1 à 3, lesdits éléments en saillie du bouchon 1 sont trois pions 15 régulièrement répartis sur le pourtour de la partie basse dudit bouchon 1. Le diamètre desdits pions 15 est sensiblement similaire à la largeur de la rainure 17 de guidage pour permettre à au moins un des pions 15, voire à l'ensemble desdits pions 15, de coopérer avec celle-ci.In the embodiment shown in Figures 1 to 3 , said elements projecting from the plug 1 are three pins 15 regularly distributed around the periphery of the lower part of said plug 1. The diameter of said pins 15 is substantially similar to the width of the guide groove 17 to allow at least one of the pieces 15, or all of said pins 15, to cooperate with it.

Ledit bouchon 1 représenté aux figures 1 à 3 est conçu pour venir se fixer sur le goulot 3 représenté à la figure 6. Dans ce mode de réalisation, ledit goulot 3 comprend trois rainures 17 régulièrement réparties sur le pourtour de la surface externe dudit goulot 3. Lesdites rainures 17 s'étendent sur la surface externe dudit goulot 3 d'une extrémité supérieure située vers un orifice 19 de sortie du goulot 3 à une extrémité inférieure opposée à ladite extrémité supérieure dudit goulot 3. Lesdites rainures 17 comprennent notamment une entrée 171 située à proximité dudit orifice 19 de sortie dudit goulot 3. Chacune des rainures 17 s'étend entre deux bords 17a, s'étendant radialement depuis un fond 17b de la dite rainure 17.Said stopper 1 represented in Figures 1 to 3 is designed to be fixed on the neck 3 shown in the figure 6 . In this embodiment, said neck 3 comprises three grooves 17 regularly distributed around the periphery of the outer surface of said neck 3. Said grooves 17 extend on the outer surface of said neck 3 from an upper end located towards an orifice 19 of outlet of the neck 3 at a lower end opposite said upper end of said neck 3. Said grooves 17 include an inlet 171 located near said outlet orifice 19 of said neck 3. Each of the grooves 17 extends between two edges 17a, s extending radially from a bottom 17b of said groove 17.

De préférence, le nombre de rainures 17 est identique au nombre d'éléments en saillie 15 du dudit bouchon 1.Preferably, the number of grooves 17 is identical to the number of projecting elements 15 of said plug 1.

De façon avantageuse, pour permettre le passage du bouchon 1 d'une position d'ouverture à une position de fermeture et inversement, ladite rainure 17 présente des portions de guidage successives. Il peut s'agir notamment d'une première portion 172 assurant l'engagement de l'élément en saillie 15 correspondant dans ladite rainure 17 et/ou le maintien dudit bouchon 1 dans une position d'attente (figure 7) et d'autres portions 173, 174, 175 successives permettant le passage de la position d'ouverture à la position de fermeture (figure 8) et inversement.Advantageously, to allow the passage of the plug 1 from an open position to a closed position and vice versa, said groove 17 has successive guide portions. It may be in particular a first portion 172 ensuring the engagement of the corresponding projecting element 15 in said groove 17 and / or the holding of said cap 1 in a waiting position ( figure 7 ) and other successive portions 173, 174, 175 allowing the passage from the open position to the closed position ( figure 8 ) and vice versa.

Dans le mode de réalisation du goulot 3 représenté à la figure 6, les trois rainures 17 présentent chacune une première portion 172 verticale par rapport à l'axe Z-Z.In the embodiment of the neck 3 shown in FIG. figure 6 , the three grooves 17 each have a first portion 172 vertical with respect to the ZZ axis.

Cette première portion 172 permet notamment l'engagement dudit bouchon 1 dans la rainure 17 mais également son maintien en position d'attente, en particulier lorsque le bouchon 1 comprend un poinçon. Cette première portion 172 est suivie par une seconde portion 173 qui est hélicoïdale de pente x, puis par une troisième portion 174 qui est hélicoïdale de pente y. La pente y de la troisième portion 174 hélicoïdale est supérieure à la pente x la deuxième portion 173 hélicoïdale. Ces deux portions 173, 174 permettent le passage dudit bouchon 1 de la position d'ouverture et/ou d'attente à la position de fermeture ou de la position de fermeture à la position d'ouverture. Ladite rainure 17 se termine enfin par une dernière portion 175 qui est horizontale par rapport à l'axe Z-Z. Lorsque les éléments en saillie 15 dudit bouchon on atteint cette dernière portion 175, le bouchon 1 est en position de fermeture (figure 8) et le réceptacle est fermé de manière étanche.This first portion 172 allows in particular the engagement of said plug 1 in the groove 17 but also its holding in the waiting position, in particular when the plug 1 comprises a punch. This first portion 172 is followed by a second portion 173 which is helical x slope, then by a third portion 174 which is helical slope y. The slope y of the third helical portion 174 is greater than the slope x the second helical portion 173. These two portions 173, 174 allow the passage of said plug 1 from the open position and / or waiting to the closed position or the closed position to the open position. Said groove 17 finally ends with a last portion 175 which is horizontal with respect to the ZZ axis. When the projecting elements 15 of said cap reaches the latter portion 175, the cap 1 is in the closed position ( figure 8 ) and the receptacle is sealed.

Cette configuration des rainures 17 permet à l'utilisateur de faire passer le bouchon 1 d'une position d'ouverture à une position de fermeture et inversement par un mouvement esentiellement hélicoïdal similaire à celui d'un bouchon classique pourvu d'un filet de vissage.This configuration of the grooves 17 allows the user to move the plug 1 from an open position to a closed position and vice versa by a substantially helical movement similar to that of a conventional plug provided with a screw thread .

Ledit bouchon 1 comprend également trois ouvertures 21 situées sur la paroi supérieure 13 dudit bouchon 1. Les ouvertures 21 sont notamment localisées sur la périphérie de la paroi supérieure 13 au droit des éléments en saillie 15 dudit bouchon 1 et sont régulièrement réparties sur la paroi supérieure 13 dudit bouchon 1.Said cap 1 also comprises three openings 21 located on the upper wall 13 of said plug 1. The openings 21 are in particular located on the periphery of the upper wall 13 to the right of the projecting elements 15 of said plug 1 and are regularly distributed on the upper wall 13 of said plug 1.

Lesdites ouvertures 21 correspondent au passage d'une zone en forme de broches d'une partie du moule servant à obtenir une partie supérieure desdits éléments en saillie. En effet, pour fabriquer un objet creux comprenant dans sa partie creuse au moins un élément en saillie, tel que le bouchon 1 de l'invention, le moulage se fait, par exemple, par-dessus et par-dessous, c'est-à-dire une partie du moule vient à l'intérieur de l'objet par le haut et une autre partie vient à l'intérieur par le bas de l'objet. L'ouverture 21 sur la paroi supérieure du bouchon 1 permet ainsi, l'introduction de la partie supérieure du moule pour la formation des éléments en saillie 15.Said openings 21 correspond to the passage of a pin-shaped zone of a portion of the mold used to obtain an upper part of said projecting elements. Indeed, to manufacture a hollow object comprising in its hollow portion at least one projecting element, such as the plug 1 of the invention, the molding is, for example, above and below, that is, ie one part of the mold comes inside the object from above and another part comes inside from the bottom of the object. The opening 21 on the upper wall of the plug 1 thus allows the introduction of the upper part of the mold for the formation of the projecting elements 15.

De préférence, le nombre d'ouvertures 21 est identique au nombre d'éléments en saillie 15 du dudit bouchon 1.Preferably, the number of openings 21 is identical to the number of projecting elements 15 of said plug 1.

Ainsi de façon avantageuse, le bouchon 1 est issu de moulage et il est réalisé en matière plastique, notamment en matériau thermoplastique, tel qu'une polyoléfine comme le polypropylène, le polyéthylène, un copolymère de ceux-ci ou un mélange de ceux-ci.Advantageously, the plug 1 is molded and is made of plastics material, in particular thermoplastic material, such as a polyolefin such as polypropylene, polyethylene, a copolymer thereof or a mixture thereof .

De façon avantageuse, le bouchon 1 est réalisée en une seule pièce.Advantageously, the plug 1 is made in one piece.

Pour conférer une étanchéité entre le bouchon 1 et le goulot 3, et notamment assurer l'étanchéité du tube 5 lorsque le bouchon 1 est en position de fermeture, le bouchon 1 comprend également un élément d'étanchéité 23, notamment un élément déformable. Ici, ledit élément d'étanchéité 23 est situé sur une surface interne de la paroi supérieure 13, radialement en retrait desdites ouvertures 21 dudit bouchon 1. Il s'agit, ici, d'une surépaisseur de matière sur la surface interne de la paroi supérieure dudit bouchon 1 qui correspond à un jonc d'étanchéité 23 situé radialement en retrait desdites ouvertures 21. Ledit jonc d'étanchéité 23 est configuré pour coopérer avec un siège de jonc 25 prévue sur une surface intérieure à l'extrémité supérieure dudit goulot 3 lorsque ledit bouchon 1 est en position de fermeture comme cela est visible sur la figure 8. Autrement dit, en position de fermeture, ledit onc 23 est comprimé sur le siège 25. Ledit jonc pourra comprendre une lèvre déformable.To provide a seal between the cap 1 and the neck 3, and in particular to seal the tube 5 when the cap 1 is in the closed position, the cap 1 also comprises a sealing member 23, in particular a deformable element. Here, said sealing member 23 is located on an inner surface of the upper wall 13, radially recessed from said apertures 21 of said cap 1. This is, here, an extra thickness of material on the inner surface of the wall upper of said plug 1 which corresponds to a sealing ring 23 located radially recessed from said openings 21. Said sealing ring 23 is configured to cooperate with a ring seat 25 provided on an inner surface at the upper end of said neck 3 when said plug 1 is in the closed position as is visible on the figure 8 . In other words, in the closed position, said nail 23 is compressed on the seat 25. Said ring may comprise a deformable lip.

De façon avantageuse, le nombre d'éléments en saillie 15 dudit bouchon 1, le nombre d'ouvertures 21 dudit bouchon 1 et le nombre de rainures 17 dudit goulot 3 sont identiques. Dans les modes de réalisation représentés ici, le bouchon 1 comprend trois éléments en saillie 15 et trois ouvertures 21 et le goulot 3 comprend trois rainures 17 de guidage.Advantageously, the number of projecting elements 15 of said plug 1, the number of openings 21 of said plug 1 and the number of grooves 17 of said neck 3 are identical. In the embodiments shown here, the plug 1 comprises three projecting elements 15 and three openings 21 and the neck 3 comprises three guide grooves 17.

Dans un autre mode de réalisation, représenté aux figures 4, 5, 7 et 8, le bouchon 1 comprend les mêmes éléments que le bouchon 1 du mode de réalisation précédent (figures1 à 3). Dans ce mode de réalisation, ledit bouchon 1 est aussi conçu pour venir se fixer sur le goulot 3 représenté à la figure 6. Ledit bouchon 1 comprend en outre un poinçon 27 faisant saillie dudit bouchon 1. Ledit poinçon 27 est notamment issu de matière dudit bouchon 1.In another embodiment, shown in Figures 4, 5, 7 and 8 , the plug 1 comprises the same elements as the plug 1 of the previous embodiment ( Figures1 to 3 ). In this embodiment, said cap 1 is also designed to be fixed on the neck 3 shown in FIG. figure 6 . Said stopper 1 further comprises a punch 27 protruding from said stopper 1. Said punch 27 is notably derived from the material of said stopper 1.

Le poinçon 27 est en particulier constitué d'une saillie de matière issue de la face interne de la paroi supérieure du bouchon 1. Une partie supérieure du poinçon 27 est ainsi entouré par la paroi périphérique 11 du bouchon 1. L'extrémité libre du poinçon 27 se situe du même côté de la paroi supérieure du bouchon 1 que les éléments en saillie 15.The punch 27 is in particular constituted by a projection of material coming from the internal face of the upper wall of the stopper 1. An upper part of the punch 27 is thus surrounded by the peripheral wall 11 of the stopper 1. The free end of the punch 27 is on the same side of the upper wall of the plug 1 as the projecting elements 15.

Ledit poinçon 27 est configuré de manière à être inséré à l'intérieur du goulot 3 de la tête de tube 7 lorsque le bouchon 1 est fixé sur ledit goulot 3.Said punch 27 is configured to be inserted inside the neck 3 of the tube head 7 when the plug 1 is fixed on said neck 3.

La tête de tube 7 représentée sur les figures 7 et 8, comprend en outre un insert 29 plein formant un opercule 31 obturant une extrémité interne du goulot 3 débouchant dans un volume intérieur du réceptacle, en partie basse dudit goulot 3.The tube head 7 shown on the Figures 7 and 8 , further comprises a solid insert 29 forming a lid 31 closing an inner end of the neck 3 opening into an interior volume of the receptacle, in the lower part of said neck 3.

Plus précisément, l'insert 29 comprend une section périphérique, typiquement de forme tronconique ou de disque, et une section centrale formant ledit opercule 31, dont le diamètre correspond typiquement au diamètre interne du goulot 3.More specifically, the insert 29 comprises a peripheral section, typically of frustoconical or disc shape, and a central section forming said lid 31, whose diameter typically corresponds to the internal diameter of the neck 3.

Ledit poinçon 27 permet la découpe et/ou la perforation de l'opercule 31. La découpe est avantageusement partielle, de manière à ce que la ou les portions de l'opercule 31 ayant été découpées demeurent liées au reste de l'insert 29, prévenant ainsi tout mélange du matériau formant l'insert 29 avec un produit contenu dans le réceptacle associé, et une éventuelle distribution de ce matériau à l'utilisateur.Said punch 27 allows the cutting and / or perforation of the lid 31. The cutting is advantageously partial, so that the portion or portions of the lid 31 having been cut remain connected to the rest of the insert 29, thus preventing any mixing of the material forming the insert 29 with a product contained in the associated receptacle, and possible distribution of this material to the user.

Ledit poinçon 27 présente, ici, une section cylindrique de révolution, dont une extrémité libre est avantageusement munie de moyens de découpe de manière à ce que lorsque le bouchon 1 est fixé sur le goulot 3 du réceptacle, l'extrémité libre du poinçon 27 soit insérée dans le goulot 3. Lesdits moyens de découpe peuvent être une forme en biseau de l'extrémité libre, des dents et/ou des encoches de découpe, par exemple, régulièrement réparties sur le pourtour de l'extrémité libre du poinçon 27. L'exemple de poinçon 27 représenté aux figures 4, 5, 7 et 8 est un poinçon 27 de section cylindrique de révolution, dont l'extrémité libre est munie de trois dents 27a de faible hauteur et régulièrement réparties sur le pourtour de son extrémité libre.Said punch 27 has, here, a cylindrical section of revolution, a free end is advantageously provided with cutting means so that when the cap 1 is fixed on the neck 3 of the receptacle, the free end of the punch 27 is inserted in the neck 3. Said cutting means may be a beveled shape of the free end, teeth and / or cutting notches, for example, evenly distributed around the free end of the punch 27. L example of punch 27 shown in Figures 4, 5, 7 and 8 is a punch 27 of cylindrical section of revolution, the free end is provided with three teeth 27a of low height and evenly distributed around the periphery of its free end.

Le bouchon 1 et plus particulièrement le poinçon 27 sont configurés de manière à ce qu'un seul et même mouvement essentiellement hélicoïdal du bouchon 1 soit nécessaire pour faire passer ledit bouchon 1 d'une position d'ouverture à une position de fermeture, pour insérer ledit poinçon 27 à l'intérieur du goulot 3 et pour percer l'opercule 31, lors de la première utilisation.The stopper 1 and more particularly the punch 27 are configured so that a single and essentially helical movement of the stopper 1 is necessary to move said stopper 1 from an open position to a closed position, to insert said punch 27 inside the neck 3 and to pierce the lid 31, during the first use.

Dans ce mode de réalisation, lesdites rainures 17 du goulot 3 comprennent avantageusement deux éléments en saillie 33a, 33b configurés pour coopérer avec un des éléments en saillie 15 dudit bouchon 1 pour maintenir ledit bouchon 1 en position d'attente (figure 7), dans laquelle ledit éventuel poinçon 27 peut être est maintenu à distance de l'opercule 31. Il s'agit de deux ergots 33a, 33b situés sur la surface externe dudit goulot 3 à proximité de l'entrée 171 de ladite rainure 17. Plus particulièrement, un premier ergot 33a est situé à l'entrée 171 de la première portion de la rainure 17. Cet ergot 33a limite le mouvement axial vers le haut selon l'axe Z-Z dudit bouchon 1 et permet de maintenir ledit bouchon 1 fixé sur ledit goulot 3 et d'éviter un retrait non désiré dudit bouchon 1. Le second ergot 33b est situé entre la première 172 et la seconde 173 portions de la rainure 17. Il permet de limiter le mouvement en rotation dudit bouchon 1 et notamment la sortie du bouchon 1 de sa position d'attente et son engagement dans une position où l'opercule 31 serait perforé et/ou découpé. Autrement dit, ce second ergot 33b permet de maintenir le poinçon 27 éloigné de l'opercule 31 et d'éviter la perforation et/ou la découpe de celui-ci sans l'intervention de l'utilisateur avant la première utilisation.In this embodiment, said grooves 17 of the neck 3 advantageously comprise two projecting elements 33a, 33b configured to cooperate with one of the projecting elements 15 of said plug 1 to maintain said plug 1 in the waiting position ( figure 7 ), in which said optional punch 27 can be kept at a distance from the cover 31. These are two lugs 33a, 33b located on the outer surface of said neck 3 near the inlet 171 of said groove 17. More particularly, a first lug 33a is located at the inlet 171 of the first portion of the groove 17. This lug 33a limits the upward axial movement along the axis ZZ of said cap 1 and keeps said cap 1 fixed on said neck 3 and avoid unwanted withdrawal of said cap 1. The second lug 33b is located between the first 172 and second 173 portions of the groove 17. It limits the rotational movement of said cap 1 and in particular the output plug 1 of its waiting position and its engagement in a position where the lid 31 would be perforated and / or cut. In other words, this second lug 33b keeps the punch 27 away from the lid 31 and avoid perforation and / or cutting thereof without the intervention of the user before the first use.

Dans ce mode de réalisation, ledit goulot 3 comprend avantageusement une rampe 35 de guidage comme cela est visible à la figure 6. Ladite rampe 35 de guidage est configurée pour coopérer avec au moins un élément en saillie 15 dudit bouchon 1 pour positionner un desdits éléments en saillie 15 à l'entrée 171 de ladite rainure 17. La rampe 35 de guidage permet de guider un des éléments en saillie 15 du bouchon 1 dans la première portion 172 de la rainure 17 de guidage. Ladite rampe 35 de guidage est visible dans la figure 6.In this embodiment, said neck 3 advantageously comprises a guide ramp 35 as can be seen in FIG. figure 6 . Said guide ramp 35 is configured to cooperate with at least one protruding element 15 of said plug 1 to position one of said projecting elements 15 at the inlet 171 of said groove 17. The guide ramp 35 serves to guide one of the elements in question. protrusion 15 of the plug 1 in the first portion 172 of the groove 17 for guiding. Said guide ramp 35 is visible in the figure 6 .

De façon avantageuse, ladite rampe 35 de guidage présente une direction de guidage inverse à la direction de guidage de la dite rainure 17 pour le passage dudit bouchon 1 de la position d'attente à la position de fermeture. Ainsi, pour positionner un desdits éléments en saillie 15 dudit bouchon 1 dans l'entrée de ladite rainure 17, il est nécessaire de faire un mouvement de rotation dans un sens. Ce mouvement de rotation est généralement réalisé par une machine de manière automatisée. Puis, une fois ledit bouchon 1 mis en position d'attente, il est nécessaire de faire un mouvement de rotation dans un sens opposé, généralement dans le sens de rotation classique de fermeture d'un bouchon 1 qui est le plus souvent le sens des aiguilles d'une montre, pour sortir le bouchon 1 de la position d'attente et amorcer la fermeture dudit bouchon 1 et/ou la découpe et/ou la perforation dudit opercule 31 par le poinçon 27. Ce double sens de rotation, permet d'éviter que la machine, lors de la mise en place d'un bouchon 1 muni d'un poinçon 27 en position d'attente, effectue une rotation trop importante et amorce une position d'utilisation dans laquelle l'opercule 31 est découpé et/ou perforé et que le poinçon 27 endommage l'opercule 31 avant l'utilisation du tube 5.Advantageously, said guide ramp 35 has a reverse guide direction to the guide direction of said groove 17 for the passage of said plug 1 from the waiting position to the closed position. Thus, to position one of said projecting elements 15 of said plug 1 in the inlet of said groove 17, it is necessary to make a rotational movement in one direction. This rotational movement is generally performed by a machine in an automated manner. Then, once said plug 1 put in the waiting position, it is necessary to make a rotational movement in an opposite direction, generally in the conventional direction of rotation of a cap 1 which is usually the meaning of clockwise, to release the stopper 1 from the standby position and to initiate the closing of said stopper 1 and / or the cutting and / or the perforation of said cover 31 by the punch 27. This double direction of rotation permits avoid that the machine, during the establishment of a plug 1 provided with a punch 27 in the waiting position, rotates too much and initiates a position of use in which the lid 31 is cut and or perforated and that the punch 27 damages the lid 31 before using the tube 5.

De façon avantageuse ladite rampe 35 peut également comprendre une butée pour forcer l'arrêt d'un desdits éléments en saillie 15 du bouchon 1 au niveau de l'entrée de la rainure 17. Ici, la butée est une prolongation 37 de la première portion de la rainure 17 en direction de l'orifice du goulot 3.Advantageously, said ramp 35 may also comprise an abutment to force the stopping of one of said projecting elements 15 of the stopper 1 at the inlet of the groove 17. Here, the abutment is an extension 37 of the first portion of the groove 17 in the direction of the orifice of the neck 3.

Ledit élément d'étanchéité 23 est ici réalisé par une surépaisseur de matière, annulaire, de la base du poinçon 27.Said sealing element 23 is here produced by an extra thickness of material, annular, of the base of the punch 27.

La paroi supérieure pourra être surmontée d'autres parties du bouchon, tout en conservant son orientation transversale à l'axe Z-Z.The upper wall may be surmounted by other parts of the plug, while maintaining its transverse orientation to the Z-Z axis.
