Description

DESCRIPTION DESCRIPTION
TITRE : Bouchon pour la fermeture d'un réceptacle ainsi qu'un ensemble comprenant ledit bouchon TITLE: Stopper for closing a receptacle as well as a set comprising said stopper
La présente invention concerne le domaine des bouchons pour réceptacle. The present invention relates to the field of caps 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. Le bouchon est également muni d’un élément d’étanchéité permettant de renforcer la fermeture. Conventionally, the caps are attached to the opening of a receptacle, such as a neck, by screwing. The stopper and the neck are then provided with complementary screw threads cooperating together. When the user wishes to close or open the receptacle, he performs a screwing or unscrewing movement in one direction or the other. The cap also has a sealing element to strengthen the closure.
L’obtention de bouchons avec un filet de vissage présente cependant des inconvénients, notamment de démoulage du bouchon. Obtaining stoppers with a screw thread, however, has drawbacks, in particular the release of the cap.
Il existe également des bouchons dont les filets de vissage sont remplacés par un ou plusieurs éléments en saillie au profil circulaire coopérant avec une rainure située sur le goulot. Le ou les éléments en saillie du bouchon peuvent être obtenus par moulage. 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 une ouverture sur sa paroi supérieure au droit des éléments en saillie. There are also stoppers whose screw threads are replaced by one or more projecting elements with a circular profile cooperating with a groove located on the neck. The protruding element or elements of the stopper can be obtained by molding. Part of the mold with the impression of the first part of the stopper comes from the top and another part with the impression of the rest of the stopper comes from the bottom. For this type of molding, the cap has an opening on its upper wall in line with the projecting elements.
Dans cette configuration, la disposition de l’élément d’étanchéité est limitée par la présence des ouvertures sur sa paroi supérieure. En effet, pour assurer l’étanchéité avec le réceptacle pour un tel bouchon et ce malgré les ouvertures, il est nécessaire de positionner l’élément d’étanchéité de sorte que le produit délivré ne passe pas par lesdites ouvertures de la paroi supérieure. De plus, une telle disposition des ouvertures est incompatible avec certains bouchons comme par exemple des bouchons de type capsule service (flip top). In this configuration, the arrangement of the sealing element is limited by the presence of the openings on its upper wall. Indeed, to seal with the receptacle for such a stopper despite the openings, it is necessary to position the sealing element so that the product delivered does not pass through said openings in the upper wall. In addition, such an arrangement of the openings is incompatible with certain caps such as, for example, caps of the service capsule type (flip top).
Pour pallier ce premier inconvénient, la présente invention propose, selon un premier aspect, un bouchon configuré pour la fermeture d’un réceptacle comprenant un goulot, ledit bouchon comprenant : To overcome this first drawback, the present invention provides, according to a first aspect, a stopper configured for closing a receptacle comprising a neck, said stopper comprising:
- une paroi supérieure et une paroi périphérique s’étendant transversalement à ladite paroi supérieure, - an upper wall and a peripheral wall extending transversely to said upper wall,
- 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 à une seconde position, - au moins une ouverture située sur la paroi périphérique dudit bouchon, la ou les dites ouvertures étant au droit des éléments en saillie dudit bouchon. - at least one projecting element configured to cooperate with a groove located on said neck so that the stopper passes from a first position to a second position, - At least one opening located on the peripheral wall of said stopper, said opening (s) being in line with the projecting elements of said stopper.
Selon ce premier aspect de l’invention, la présence d’au moins une ouverture sur la paroi périphérique du bouchon permet un moulage/démoulage facilité par rapport à un bouchon présentant un filet de vissage et par rapport à un bouchon présentant des ouvertures sur sa paroi supérieure. De plus, cette configuration permet une plus grande liberté de positionnement de l’élément d’étanchéité et est notamment compatible avec un bouchon de type capsule service. According to this first aspect of the invention, the presence of at least one opening on the peripheral wall of the stopper allows easier molding / demolding compared to a stopper having a screw thread and compared to a stopper having openings on its top wall. In addition, this configuration allows greater freedom of positioning of the sealing element and is notably compatible with a cap of the service capsule type.

- l’élément d’étanchéité est situé sur une surface interne de la paroi supérieure dudit bouchon, - the sealing element is located on an internal surface of the upper wall of said plug,
- le nombre d’éléments en saillie dudit bouchon et le nombre d’ouvertures dudit bouchon sont identiques, - the number of protruding elements of said plug and the number of openings of said plug are identical,
- le nombre d’éléments en saillie dudit bouchon et le nombre de rainures dudit goulot sont identiques, - the number of projecting elements of said stopper and the number of grooves of said neck are identical,
- le ou lesdits éléments en saillie dudit bouchon sont localisés sur une partie basse dudit bouchon, the said protruding element (s) of said stopper are located on a lower part of said stopper,
- la ou lesdites ouvertures dudit bouchon sont régulièrement réparties sur la paroi périphérique dudit bouchon, - Said opening (s) of said plug are regularly distributed over the peripheral wall of said plug,
- le ou lesdits éléments en saillie dudit bouchon sont régulièrement répartis sur la paroi périphérique dudit bouchon, - Said element or elements projecting from said stopper are regularly distributed over the peripheral wall of said stopper,
- le bouchon s’étend le long d’un axe longitudinal (A), la ou lesdites ouvertures dudit bouchon s’étendant le long dudit axe longitudinal (A), - the stopper extends along a longitudinal axis (A), said opening (s) of said stopper extending along said longitudinal axis (A),
- le ou lesdits éléments en saillie présentent un profil sensiblement carré, - l’élément d’étanchéité est un jonc d’étanchéité formé par une surépaisseur de matière sur la surface interne de la paroi supérieure dudit bouchon, - said protruding element or elements have a substantially square profile, the sealing element is a sealing ring formed by an extra thickness of material on the internal surface of the upper wall of said plug,
- le jonc d’étanchéité est configuré pour coopérer avec un siège de jonc prévu sur une surface intérieure à l’extrémité supérieure dudit goulot lorsque ledit bouchon est dans sa seconde position, - the sealing ring is configured to cooperate with a ring seat provided on an inner surface at the upper end of said neck when said stopper is in its second position,
- ledit bouchon comprend en outre un poinçon adapté pour découper et/ou percer un opercule obturant une extrémité interne du goulot débouchant dans un volume intérieur du réceptacle, - Said stopper further comprises a punch suitable for cutting and / or piercing a cover closing an internal end of the neck opening into an internal volume of the receptacle,
- le poinçon présente une forme de fût dont l’extrémité supérieur est ouverte de sorte à pouvoir communiquer avec un volume externe du réceptacle lorsque ledit bouchon est dans sa seconde position, - the punch has the shape of a barrel, the upper end of which is open so as to be able to communicate with an external volume of the receptacle when said stopper is in its second position,
- le bouchon comprend un couvercle rabattable au niveau de la paroi supérieure dudit bouchon, ledit couvercle étant mobile entre une position ouverte et une position fermée de sorte à pouvoir respectivement permettre et empêcher l’accès au volume externe du réceptacle, - the stopper comprises a hinged cover at the level of the upper wall of said stopper, said cover being movable between an open position and a closed position so as to be able to respectively allow and prevent access to the external volume of the receptacle,
- le bouchon est configuré pour que le poinçon soit maintenu éloigné dudit opercule dans une position d’attente. - the cap is configured so that the punch is kept away from said cover in a waiting position.
Un autre inconvénient des bouchons présentant des éléments en saillie au profil circulaire coopérant avec une rainure située sur le goulot est la surface d’appui dudit élément en saillie contre ladite rainure. En effet, avec un élément en saillie de forme circulaire, seul une faible surface de l’élément en saillie est effectivement en appui contre la rainure. Le guidage n’est ainsi pas optimal. De plus, dans le cas d’un maintien en position d’attente par des butées, un élément en saillie de forme circulaire ne génère que peu de contraintes contre les butées et risque ainsi de dépasser la position d’attente de manière non intentionnelle. Another drawback of caps having projecting elements with a circular profile cooperating with a groove located on the neck is the bearing surface of said protruding element against said groove. In fact, with a protruding element of circular shape, only a small surface of the protruding element actually bears against the groove. The guidance is therefore not optimal. In addition, in the case of holding in the waiting position by stops, a protruding element of circular shape generates little stress against the stops and thus risks exceeding the waiting position unintentionally.
Pour pallier cet autre inconvénient, la présente invention propose, selon un deuxième aspect, un bouchon configuré pour la fermeture d’un réceptacle comprenant un goulot, ledit bouchon comprenant 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 à une seconde position, ledit élément en saillie présentant une face périphérique comprenant une première et une deuxième portions latérales, une portion inférieure et une portion supérieure, l’une au moins desdites portions étant sensiblement plane. To overcome this other drawback, the present invention provides, according to a second aspect, a stopper configured for closing a receptacle comprising a neck, said stopper comprising at least one projecting element configured to cooperate with a groove located on said neck. so that the stopper passes from a first position to a second position, said protruding member having a peripheral face comprising a first and a second side portions, a lower portion and an upper portion, at least one of said portions being substantially flat.
Selon ce deuxième aspect de l’invention, la présence d’un élément en saillie présentant au moins une portion de sa face périphérique plane permet de générer une zone d’appui plus importante et donc d’améliorer le guidage dudit élément en saillie dans la rainure du goulot. De plus, ou alternativement, un tel élément en saillie permet de générer des contraintes plus fortes lors du passage de butée de maintien en position d’attente et diminue ainsi les risques de dépasser la position d’attente de manière non intentionnelle. According to this second aspect of the invention, the presence of a projecting element having at least a portion of its planar peripheral face makes it possible to generate a larger bearing zone and therefore to improve the guidance of said projecting element in the neck groove. In addition, or alternatively, such a protruding element makes it possible to generate greater stresses when passing from the holding stopper to the waiting position and thus reduces the risks of exceeding the waiting position unintentionally.

Comme illustré aux figures 1 à 9, 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 FIGS. 1 to 9, the invention relates to a stopper 1 configured for closing a receptacle comprising a neck 3. Said stopper 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 stopper 1.
Dans les exemples illustrés ici, le réceptacle est un tube comprenant une tête de tube munit dudit goulot 3 et d’une épaule 9. In the examples illustrated here, the receptacle is a tube comprising a tube head provided with said neck 3 and a shoulder 9.
De manière générale, ledit bouchon 1 comprend une paroi supérieure 13 et une paroi périphérique 1 1 s’étendant transversalement à ladite paroi supérieure 13. Comme illustré aux figures 2 et 4, le bouchon 1 s’étend le long d’un axe longitudinal (A) passant en son centre. Ladite paroi périphérique 1 1 s’étend ici perpendiculairement à ladite paroi supérieure 13, par exemple légèrement en retrait d’une périphérie de ladite paroi supérieure 13. In general, said plug 1 comprises an upper wall 13 and a peripheral wall 11 extending transversely to said upper wall 13. As illustrated in Figures 2 and 4, the plug 1 extends along a longitudinal axis ( A) passing through its center. Said peripheral wall 11 extends here perpendicular to said upper wall 13, for example slightly set back from a periphery of said upper wall 13.
Selon l’invention, le bouchon 1 , en particulier la surface interne de sa paroi périphérique 1 1 est exempte de filet de vissage. En revanche, ledit bouchon 1 comprend au moins un élément en saillie 15. Le ou lesdits éléments en saillie 15 sont configurés pour coopérer avec une rainure 17 de guidage située sur le goulot 3 de manière à ce que le bouchon 1 passe d’une première position dite position d’ouverture, à une seconde position dite position de fermeture. Ledit bouchon 1 comprend au moins une ouverture 21 située sur la paroi périphérique 1 1 dudit bouchon 1 . Comme cela est visible notamment aux figures 3, 4 et 5, la ou les ouvertures 21 sont au droit des éléments en saillie 15 dudit bouchon 1 . According to the invention, the cap 1, in particular the internal surface of its peripheral wall 11, is free from screw thread. On the other hand, said stopper 1 comprises at least one protruding element 15. Said protruding element or elements 15 are configured to cooperate with a guide groove 17 situated on the neck 3 so that the stopper 1 passes from a first position called the open position, at a second position called the closed position. Said stopper 1 comprises at least one opening 21 located on the peripheral wall 1 1 of said stopper 1. As can be seen in particular in FIGS. 3, 4 and 5, the opening (s) 21 are in line with the projecting elements 15 of said plug 1.
Les ouvertures 21 correspondent au passage d’une zone en forme de broches d’une partie du moule servant à obtenir lesdits éléments en saillie 15 en particulier une partie supérieure de ladite saillie 15. La présence d’au moins une ouverture 21 sur la paroi périphérique 1 1 du bouchon 1 permet un moulage/démoulage facilité par rapport à un bouchon présentant un filet de vissage et par rapport à un bouchon présentant des ouvertures sur sa paroi supérieure en évitant un démoulage par dévissage ou un démoulage en force. De plus, cette configuration permet une plus grande liberté de positionnement de l’élément d’étanchéité et est notamment compatible avec un bouchon de type capsule service. The openings 21 correspond to the passage of a pin-shaped zone of a part of the mold serving to obtain said projecting elements 15, in particular an upper part of said projection 15. The presence of at least one opening 21 on the wall Peripheral 1 1 of the stopper 1 allows easy molding / demoulding compared to a stopper having a screw thread and compared to a stopper having openings on its upper wall avoiding demoulding by unscrewing or demoulding by force. In addition, this configuration allows greater freedom in positioning the sealing element and is in particular compatible with a cap of the service capsule type.
Avantageusement, le bouchon 1 comprend un élément d’étanchéité 23 configuré pour conférer une étanchéité entre le bouchon 1 et le goulot 3. En projection sur un plan orthogonal à l’axe (A), ledit élément d’étanchéité 23 est radialement décalé par rapport audit élément en saillie 15. Advantageously, the stopper 1 comprises a sealing element 23 configured to impart a seal between the stopper 1 and the neck 3. In projection on a plane orthogonal to the axis (A), said sealing element 23 is radially offset by report to said protruding element 15.
Avantageusement encore, ledit élément d’étanchéité 23 est situé sur une surface interne de la paroi supérieure 13 dudit bouchon 1 . Also advantageously, said sealing element 23 is located on an internal surface of the upper wall 13 of said plug 1.
Préférentiellement, l’élément d’étanchéité 23 est situé radialement en retrait des ouvertures 21 dudit bouchon 1 pour assurer l’étanchéité dudit réceptacle. Preferably, the sealing element 23 is located radially set back from the openings 21 of said plug 1 to ensure the sealing of said receptacle.
Ledit élément d’étanchéité 23 peut présenter différentes configurations en fonction du goulot auquel est associé le bouchon 1 selon l’invention. Avantageusement, l’élément d’étanchéité 23 est un jonc d’étanchéité formé par une surépaisseur de matière sur la surface interne de la paroi supérieure 13 dudit bouchon 1 . Ledit jonc peut notamment comprendre une lèvre déformable. Ledit jonc d’étanchéité 23 est alors configuré pour coopérer avec un siège de jonc prévu sur une surface intérieure à l’extrémité supérieure dudit goulot 3 lorsque ledit bouchon 1 est dans sa seconde position. Ainsi, lorsque le bouchon est dans sa seconde position, ledit jonc 23 est comprimé sur le siège de jonc. Said sealing element 23 may have different configurations depending on the neck with which the stopper 1 is associated according to the invention. Advantageously, the sealing element 23 is a sealing ring formed by an extra thickness of material on the internal surface of the upper wall 13 of said plug 1. Said ring can in particular comprise a deformable lip. Said sealing ring 23 is then configured to cooperate with a ring seat provided on an inner surface at the upper end of said neck 3 when said stopper 1 is in its second position. Thus, when the stopper is in its second position, said ring 23 is compressed on the ring seat.
Avantageusement, le bouchon 1 comprend un poinçon 27 adapté pour découper et/ou percer un opercule obturant une extrémité interne du goulot 3 débouchant dans un volume intérieur du réceptacle. Ledit poinçon 27 est notamment issu de matière dudit bouchon 1 . 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. Advantageously, the stopper 1 comprises a punch 27 suitable for cutting and / or piercing a cover closing an internal end of the neck 3 opening into an internal volume of the receptacle. Said punch 27 is in particular made from material of said plug 1. Said punch 27 is configured so as to be inserted inside the neck 3 of the tube head 7 when the stopper 1 is fixed on said neck 3.
Avantageusement encore, le poinçon 27 présente une forme de fût dont l’extrémité supérieur est ouverte de sorte à pouvoir communiquer avec un volume externe du réceptacle lorsque ledit bouchon 1 est dans sa seconde position. Also advantageously, the punch 27 has the shape of a barrel, the upper end of which is open so as to be able to communicate with an external volume of the receptacle when said plug 1 is in its second position.
Selon un mode de réalisation non représenté, le poinçon 27 présente une forme de fût configuré de sorte à coopérer avec une paroi interne du goulot 3 lorsque le bouchon 1 est dans sa seconde position. La paroi externe du fût est alors en contact avec la paroi interne du goulot 3 de sorte à assurer l’étanchéité du réceptacle. Dans ce mode de réalisation, le bouchon 1 est ainsi dépourvu d’élément d’étanchéité 23. De façon avantageuse, le nombre d’éléments en saillie 15 dudit bouchon 1 et le nombre d’ouvertures 21 dudit bouchon 1 sont identiques. Dans les modes de réalisation représentés ici, le bouchon 1 comprend deux éléments en saillie 15 et deux ouvertures 21 , notamment diamétralement opposés. According to an embodiment not shown, the punch 27 has the shape of a barrel configured so as to cooperate with an internal wall of the neck 3 when the stopper 1 is in its second position. The outer wall of the barrel is then in contact with the internal wall of the neck 3 so as to seal the receptacle. In this embodiment, the stopper 1 is thus devoid of sealing element 23. Advantageously, the number of projecting elements 15 of said plug 1 and the number of openings 21 of said plug 1 are identical. In the embodiments shown here, the stopper 1 comprises two projecting elements 15 and two openings 21, in particular diametrically opposed.
Avantageusement encore le nombre de rainures 17 de guidage du goulot 3 auquel est associé le bouchon 1 et le nombre d’éléments en saillie 15 dudit bouchon sont identiques. Also advantageously, the number of guide grooves 17 for the neck 3 with which the stopper 1 is associated and the number of projecting elements 15 of said stopper are identical.
Les éléments en saillie 15 du bouchon 1 selon l’invention peuvent présenter différentes configurations. Préférentiellement, le ou lesdits éléments en saillie 15 du bouchon 1 sont localisés sur une partie basse dudit bouchon 1 . The projecting elements 15 of the plug 1 according to the invention can have different configurations. Preferably, said protruding element (s) 15 of stopper 1 are located on a lower part of said stopper 1.
Avantageusement, le ou lesdits éléments en saillie 15 dudit bouchon 1 sont régulièrement répartis sur la paroi périphérique 1 1 dudit bouchon 1 . Avantageusement encore, le ou lesdits éléments en saillie 15 sont situés sur une surface interne de la paroi périphérique 1 1 dudit bouchon 1 . Préférentiellement, la ou lesdites ouvertures 21 dudit bouchon 1 sont également régulièrement réparties sur la paroi périphérique 1 1 dudit bouchon 1 . La ou lesdites rainures 17 du goulot s’étendent alors sur une surface externe dudit goulot 3. Advantageously, said protruding element or elements 15 of said plug 1 are regularly distributed over the peripheral wall 11 of said plug 1. Again advantageously, said protruding element or elements 15 are located on an internal surface of the peripheral wall 11 of said plug 1. Preferably, said opening (s) 21 of said plug 1 are also regularly distributed over the peripheral wall 11 of said plug 1. Said groove or grooves 17 of the neck then extend over an outer surface of said neck 3.
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 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 8) et d’autres portions successives permettant le passage de la position d’attente à la position de fermeture (figure 9) 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 in particular be a first portion ensuring the engagement of the corresponding projecting element 15 in said groove 17 and / or maintaining said plug 1 in a standby position (FIG. 8) and other portions successive allowing the passage from the waiting position to the closed position (Figure 9) and vice versa.
Dans le mode de réalisation représenté aux figures 7 à 9, les deux rainures 17 présentent chacune une première portion verticale par rapport à l’axe (A). Cette première portion permet notamment l’engagement dudit bouchon 1 dans la rainure 17 mais également son passage de la position d’ouverture à la position d’attente, en particulier lorsque le bouchon 1 comprend le poinçon 27. Cette première portion est suivie par une seconde portion hélicoïdale. Cette seconde portion permet le passage dudit bouchon 1 de la position d’attente à la position de fermeture et inversement. Ladite rainure 17 se termine enfin par une dernière portion qui est horizontale par rapport à l’axe Z-Z. Lorsque les éléments en saillie 15 dudit bouchon ont atteint cette dernière portion, le bouchon 1 est en position de fermeture (figure 9) et le réceptacle est fermé de manière étanche. In the embodiment shown in Figures 7 to 9, the two grooves 17 each have a first vertical portion relative to the axis (A). This first portion allows in particular the engagement of said stopper 1 in the groove 17 but also its passage from the open position to the waiting position, in particular when the stopper 1 comprises the punch 27. This first portion is followed by a second helical portion. This second portion allows the passage of said plug 1 from the standby position to the closed position and vice versa. Said groove 17 finally ends with a last portion which is horizontal with respect to the Z-Z axis. When the projecting elements 15 of said stopper have reached this last portion, the stopper 1 is in the closed position (FIG. 9) and the receptacle is closed in a sealed manner.
Dans ce mode de réalisation, ledit goulot 3 comprend avantageusement une rampe 36 de guidage comme cela est visible aux figures 7 à 9. Ladite rampe 36 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 de ladite rainure 17, le bouchon 1 étant alors en position d’ouverture. La rampe 36 de guidage permet de guider un des éléments en saillie 15 du bouchon 1 dans la première portion de la rainure 17 de guidage. Ladite rampe 36 de guidage est visible aux figures 7 à 9. In this embodiment, said neck 3 advantageously comprises a guide ramp 36 as can be seen in FIGS. 7 to 9. Said guide ramp 36 is configured to cooperate with at least one projecting element 15 of said plug 1 in order to position one of said stopper. projecting elements 15 at the entrance of said groove 17, the stopper 1 then being in open position. The guide ramp 36 makes it possible to guide one of the projecting elements 15 of the stopper 1 in the first portion of the guide groove 17. Said guide ramp 36 is visible in Figures 7 to 9.
De façon avantageuse, ladite rampe 36 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 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 est découpé et/ou perforé et que le poinçon 27 endommage l’opercule avant l’utilisation du réceptacle. Advantageously, said guide ramp 36 has a guiding direction opposite to the guiding 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 protruding elements 15 of said plug 1 in the entrance of said groove 17, it is necessary to make a rotational movement in one direction. This rotational movement is generally carried out by a machine in an automated manner. Then, once said stopper 1 is placed in the standby position, it is necessary to make a rotational movement in an opposite direction, generally in the conventional direction of rotation of closing a stopper 1 which is most often the direction of clockwise, to take the stopper 1 out of the standby position and initiate the closing of said stopper 1 and / or the cutting and / or the perforation of said cover by the punch 27. This double direction of rotation makes it possible to prevent the machine, when placing a cap 1 provided with a punch 27 in the standby position, rotates too much and initiates a position of use in which the cover is cut and / or perforated and that the punch 27 damages the cover before the receptacle is used.
De façon avantageuse ladite rampe 36 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 portion 37a d’un flanc 37 de la rainure 17. Advantageously, said ramp 36 can also comprise a stop for forcing the stop of one of said projecting elements 15 of the stopper 1 at the level of the entrance to the groove 17. Here, the stop is a portion 37a of a sidewall. 37 of groove 17.
Comme mentionné plus haut, le bouchon 1 s’étend le long d’un axe longitudinal (A). Avantageusement, la ou lesdites ouvertures 21 du bouchon 1 s’étendent le long dudit axe longitudinal (A). En d’autres termes, la ou lesdites ouvertures sont sensiblement allongées selon l’axe longitudinal (A). Cette forme allongée est visible aux figures 1 , 2 et 4. As mentioned above, the plug 1 extends along a longitudinal axis (A). Advantageously, said opening (s) 21 of the plug 1 extend along said longitudinal axis (A). In other words, said opening (s) are substantially elongated along the longitudinal axis (A). This elongated shape is visible in Figures 1, 2 and 4.
Les éléments en saillie 15 du bouchon 1 peuvent présenter différentes formes, notamment une forme de pion. Avantageusement, le ou les éléments en saillie 15 du bouchon 1 présentent un profil sensiblement carré. En d’autres termes, l’élément en saillie 15 présente une section sensiblement carré à coins arrondis ou non. La section ici considérée est la section dans un plan orthogonal au rayon de bouchon 1 . Cet aspect de l’invention sera discuté plus en détail par la suite. The projecting elements 15 of the stopper 1 may have different shapes, in particular the shape of a pin. Advantageously, the projecting element or elements 15 of the stopper 1 have a substantially square profile. In other words, the protruding element 15 has a substantially square section with rounded corners or not. The section considered here is the section in a plane orthogonal to the plug radius 1. This aspect of the invention will be discussed in more detail below.
Selon un autre mode de réalisation non représenté sur les figures, le bouchon 1 comprend un couvercle rabattable au niveau de la paroi supérieure 13 dudit bouchon 1 . Le couvercle est mobile entre une position ouverte et une position fermée de sorte à pouvoir respectivement permettre et empêcher l’accès au volume interne du réceptacle. According to another embodiment not shown in the figures, the stopper 1 comprises a hinged cover at the level of the upper wall 13 of said stopper 1. The cover is movable between an open position and a closed position so as to be able respectively to allow and prevent access to the internal volume of the receptacle.
Avantageusement, le bouchon 1 est configuré pour être immobilisé sur le goulot 3 alors que le poinçon 27 est maintenu éloigné dudit opercule, ceci dans une position dite position d’attente. Le bouchon 1 en position d’attente sur le goulot 3 est illustré à la figure 8. Advantageously, the stopper 1 is configured to be immobilized on the neck 3 while the punch 27 is kept away from said cap, this in a position called the standby position. The stopper 1 in the standby position on the neck 3 is shown in Figure 8.
Selon un deuxième aspect de l’invention, ledit élément en saillie 15 présente une face périphérique 16 comprenant une première et une deuxième portions latérales 16a, 16d, une portion inférieure 16b et une portion supérieure 16c. L’une au moins desdites portions est sensiblement plane. Les différentes faces et portions de l’élément en saillie 15 sont représentées à la figure 6. Lesdites premières et deuxièmes portions latérales relient lesdites portions inférieure et supérieure. According to a second aspect of the invention, said protruding element 15 has a peripheral face 16 comprising a first and a second lateral portion 16a, 16d, a lower portion 16b and an upper portion 16c. At least one of said portions is substantially planar. The different faces and portions of the projecting element 15 are shown in Figure 6. Said first and second side portions connect said lower and upper portions.
La présence d’un élément en saillie 15 présentant au moins une portion de sa face périphérique plane permet de générer une zone d’appui plus importante contre le goulot 3 auquel est associé le bouchon 1 . Le guidage de l’élément en saillie 15 dans la rainure du goulot 3 en est ainsi amélioré. The presence of a projecting element 15 having at least a portion of its planar peripheral face makes it possible to generate a larger bearing area against the neck 3 with which the stopper 1 is associated. The guiding of the projecting element 15 in the groove of the neck 3 is thus improved.
En pratique, comme déjà évoqué, ledit élément en saillie ou pion 15 présente une section sensiblement carrée à coins arrondis ou non. In practice, as already mentioned, said projecting element or pin 15 has a substantially square section with rounded corners or not.
Avantageusement, lorsque le bouchon 1 est monté sur le goulot 3, ledit bouchon 1 passe d’une première position, dite position d’ouverture, représentée à la figure 7 à une position d’attente représentée à la figure 8, puis de ladite position d’attente à une seconde position, dite position de fermeture, représentée à la figure 9. Lorsque le bouchon 1 passe de l’une à l’autre des positions, il effectue un mouvement de rotation et un mouvement de translation le long de l’axe longitudinal (A). Advantageously, when the stopper 1 is mounted on the neck 3, said stopper 1 passes from a first position, called the open position, shown in FIG. 7 to a standby position shown in FIG. 8, then from said position waiting at a second position, called the closed position, shown in Figure 9. When the stopper 1 passes from one of the positions to the other, it performs a rotational movement and a translational movement along the 'longitudinal axis (A).
Dans le mode de réalisation représenté aux figures 7 à 9, lorsque le bouchon 1 est monté sur le goulot 3, ledit bouchon 1 subit tout d’abord une rotation antihoraire le long de l’axe longitudinal (A) de sorte qu’un desdits éléments en saillie 15 se positionne à l’entrée de ladite rainure 17. Le bouchon 1 est alors en position d’ouverture. Lorsque le bouchon 1 passe de la position d’ouverture à la position d’attente, il subit une translation le long de l’axe longitudinal (A) en direction du goulot 3. Lorsque le bouchon 1 passe de la position d'attente à la seconde position, le bouchon réalise entre autre un mouvement de rotation le long de l’axe longitudinal (A) dans un sens de rotation appelé sens de fermeture du bouchon. Lorsque le bouchon 1 passe de la seconde position à la position d’attente, le bouchon réalise entre autre un mouvement de rotation le long de l’axe longitudinal (A) dans un sens de rotation appelé sens d’ouverture du bouchon. In the embodiment shown in Figures 7 to 9, when the stopper 1 is mounted on the neck 3, said stopper 1 first undergoes a counterclockwise rotation along the longitudinal axis (A) so that one of said projecting elements 15 is positioned at the entrance of said groove 17. The stopper 1 is then in the open position. When the stopper 1 passes from the open position to the standby position, it undergoes a translation along the longitudinal axis (A) in the direction of the neck 3. When the stopper 1 passes from the standby position to the second position, the stopper performs among other things a rotational movement along the longitudinal axis (A) in a direction of rotation called the closure direction of the stopper. When the stopper 1 passes from the second position to the standby position, the stopper performs among other things a rotational movement along the longitudinal axis (A) in a direction of rotation called the direction of opening of the stopper.
D’après le mode de réalisation illustré aux figures 7 à 9, le sens de fermeture du bouchon correspond à une rotation horaire et le sens d’ouverture du bouchon correspond à une rotation antihoraire. L’invention n’est cependant pas limitée ni au mode de réalisation illustré dans ces figures ni à ces sens de rotation. According to the embodiment illustrated in Figures 7 to 9, the closing direction of the cap corresponds to a clockwise rotation and the opening direction of the cap corresponds to a counterclockwise rotation. The invention is, however, not limited to either the embodiment illustrated in these figures or to these directions of rotation.
Avantageusement, la première portion latérale 16a prévue dans un sens d’ouverture du bouchon 1 , de la face périphérique 16 de l’élément en saillie 15, est plane. Comme illustré à la figure 7, lorsque le bouchon est dans la première position, la première portion latérale 16a vient au contact d’une première portion 37a du flanc 37 de la rainure 17 du goulot 3. Le fait que la première portion latérale 16a soir plane permet un meilleur appui contre ledit flanc 37 de ladite rainure 17. Ledit bouchon 1 est dans cette première position lors de mise en place du bouchon 1 sur le goulot 3. Cette mise en place, également appelé bouchonnage, est en particulier réalisée sur des lignes de production. Un bon appui de l’élément en saillie contre le flanc 37 de la rainure permet de limiter les incidents de production. Advantageously, the first lateral portion 16a provided in a direction of opening of the plug 1, of the peripheral face 16 of the projecting element 15, is flat. As illustrated in Figure 7, when the stopper is in the first position, the first lateral portion 16a comes into contact with a first portion 37a of the side 37 of the groove 17 of the neck 3. The fact that the first lateral portion 16a is flat allows better support against said side 37 of said groove 17. Said stopper 1 is in this first position when placing the stopper 1 on the neck 3. This installation, also called capping, is in particular carried out on production lines. Good support of the projecting element against the side 37 of the groove makes it possible to limit production incidents.
Comme illustré à la figure 8, lorsque le bouchon 1 est en position d’attente sur le goulot 3, le poinçon 27 est maintenu à distance de l’opercule. Ledit bouchon 1 est dans cette position d’attente à la fin d’un mouvement de mise en place du bouchon 1 sur le goulot 3. C’est dans cette position qu’est vendu l’ensemble 100 avant remplissage du réceptacle. C’est également dans cette position d’attente qu’est vendu l’ensemble 100 au consommateur, après remplissage du réceptacle. As illustrated in Figure 8, when the cap 1 is in the standby position on the neck 3, the punch 27 is kept away from the cap. Said stopper 1 is in this waiting position at the end of a movement of placing the stopper 1 on the neck 3. It is in this position that the assembly 100 is sold before filling the receptacle. It is also in this waiting position that the set 100 is sold to the consumer, after filling the receptacle.
Avantageusement, la portion inférieure 16b de la face périphérique 16 de l’élément en saillie 15 est également plane. Comme illustré à la figure 8, lorsque le bouchon 1 est dans la position d’attente, la portion inférieure 16b vient au contact d’une deuxième portion 37b du flanc 37 de la rainure 17 du goulot 3. Le fait que la portion inférieure 16b soit plane permet un meilleur appui contre le flanc 37 de ladite rainure 17 et un meilleur blocage en position d’attente. Advantageously, the lower portion 16b of the peripheral face 16 of the projecting element 15 is also flat. As illustrated in Figure 8, when the cap 1 is in the standby position, the lower portion 16b comes into contact with a second portion 37b of the side 37 of the groove 17 of the neck 3. The fact that the lower portion 16b either flat allows better support against the side 37 of said groove 17 and better locking in the standby position.
Comme illustré à la figure 9, lorsque le bouchon 1 est en position de fermeture, ledit poinçon 27 a percé ledit opercule. Le bouchon 1 ferme alors de manière hermétique le réceptacle sur lequel est adapté un ensemble 100. La position de fermeture peut également être qualifiée de position d’utilisation dans la mesure où la découpe de l’opercule détermine le point de départ de l’utilisation du réceptacle 100 sur lequel est monté l’ensemble de fermeture 100 selon l’invention. Le bouchon 1 peut être destiné à retourner dans sa première position de sorte à être retiré du goulot. Le bouchon 1 peut également être destiné à rester en position de fermeture. C’est notamment le cas, selon le mode de réalisation déjà évoqué, lorsque le poinçon 27 présente la forme d’un fût creux et présente une ouverture au niveau de la face supérieure du bouchon 1 . Ainsi, une fois le bouchon 1 en position de fermeture sur le goulot 3, l’accès au volume interne du réceptacle sur lequel est adapté l’ensemble 100 est possible par ladite ouverture. As illustrated in FIG. 9, when the stopper 1 is in the closed position, said punch 27 has pierced said cover. The stopper 1 then hermetically closes the receptacle on which an assembly 100 is fitted. The closed position can also be qualified as the position of use insofar as the cutout of the cover determines the starting point of use. of the receptacle 100 on which the closure assembly 100 is mounted according to invention. The stopper 1 may be intended to return to its first position so as to be removed from the neck. The stopper 1 can also be intended to remain in the closed position. This is particularly the case, according to the embodiment already mentioned, when the punch 27 has the shape of a hollow barrel and has an opening at the level of the upper face of the stopper 1. Thus, once the stopper 1 is in the closed position on the neck 3, access to the internal volume of the receptacle on which the assembly 100 is fitted is possible through said opening.
Avantageusement, la portion supérieure 16c de la face périphérique 16 de l’élément en saillie 15 est également plane. Comme illustré à la figure 9, lorsque le bouchon 1 est dans la position de fermeture, la portion supérieure 16c vient au contact d’une troisième portion 37c du flanc 37 de la rainure 17 du goulot 3. Le fait que la portion supérieure 16c soit plane permet un meilleur appui contre le flanc 37 de ladite rainure 17 et un meilleur blocage en position de fermeture. Advantageously, the upper portion 16c of the peripheral face 16 of the projecting element 15 is also flat. As illustrated in FIG. 9, when the stopper 1 is in the closed position, the upper portion 16c comes into contact with a third portion 37c of the side 37 of the groove 17 of the neck 3. The fact that the upper portion 16c is flat allows better support against the side 37 of said groove 17 and better locking in the closed position.
Avantageusement, la deuxième portion latérale 16d prévue dans le sens de fermeture du bouchon 1 , de la face périphérique 16 de l’élément en saillie 15, est également plane. Comme illustré à la figure 9, lorsque le bouchon 1 est dans la position de fermeture, la deuxième portion latérale 16d vient au contact d’une portion terminale 37d du flanc 37 de la rainure 17 du goulot 3. Le fait que la deuxième portion latérale 16d soit plane permet un meilleur appui contre le flanc 37 de ladite rainure 17 et un meilleur blocage en position de fermeture. Advantageously, the second lateral portion 16d provided in the direction of closure of the cap 1, of the peripheral face 16 of the projecting element 15, is also flat. As illustrated in FIG. 9, when the stopper 1 is in the closed position, the second lateral portion 16d comes into contact with an end portion 37d of the flank 37 of the groove 17 of the neck 3. The fact that the second lateral portion 16d is flat allows better support against the side 37 of said groove 17 and better locking in the closed position.
Selon un mode de réalisation représenté aux figures 7 à 9, la ou lesdites rainures 17 du goulot 3 comprennent au moins une protrusion 35 configurée pour coopérer avec au moins un des éléments en saillie 15 dudit bouchon 1 pour maintenir ledit bouchon 1 en position d’attente et/ou en position de fermeture. Préférentiellement, le goulot comprend une première et une deuxième protrusion 35a, 35b permettant le maintien du bouchon en position d’attente et au moins une troisième protrusion 35c permettant le maintien du bouchon en position de fermeture. According to one embodiment shown in Figures 7 to 9, said groove or grooves 17 of the neck 3 comprise at least one protrusion 35 configured to cooperate with at least one of the projecting elements 15 of said plug 1 to maintain said plug 1 in the position of. waiting and / or in the closed position. Preferably, the neck comprises a first and a second protrusion 35a, 35b allowing the stopper to be kept in the waiting position and at least a third protrusion 35c allowing the stopper to be kept in the closed position.
Avantageusement, la portion inférieure 16b et la première portion latérale 16a de la face périphérique 16 définissent entre elles un premier arrondi 16e. Avantageusement encore, la portion inférieure 16b et la deuxième portion latérale 16d de la face périphérique 16 définissent entre elles un deuxième arrondi 16f. La présence d’un premier et/ou d’un deuxième arrondi permettent de guider l’élément en saillie 15 le long de la rainure 17, contre le flanc 37 inférieur de ladite rainure 17, en particulier lors du passage de la première protrusion 35a. La présence d’un arrondi permet notamment de diminuer les contraintes appliquées par l’élément en saillie 15 contre la rainure 17. De manière avantageuse, comme représenté à la figure 6, la portion supérieure 16c et la deuxième portion latérale 16d de la face périphérique 16 définissent entre elles une première arête 16g. La présence de cette première arête 16g permet de générer une butée franche lorsque le bouchon est en position d’attente, ceci entre l'élément en saillie 15 et la protrusion 35b. Un tel contact permet de sécuriser le maintien du bouchon en position d’attente. Advantageously, the lower portion 16b and the first lateral portion 16a of the peripheral face 16 define between them a first rounding 16e. Again advantageously, the lower portion 16b and the second lateral portion 16d of the peripheral face 16 define between them a second rounding 16f. The presence of a first and / or a second rounding makes it possible to guide the projecting element 15 along the groove 17, against the lower side 37 of said groove 17, in particular during the passage of the first protrusion 35a . The presence of a rounding makes it possible in particular to reduce the stresses applied by the projecting element 15 against the groove 17. Advantageously, as shown in FIG. 6, the upper portion 16c and the second lateral portion 16d of the peripheral face 16 define between them a first edge 16g. The presence of this first ridge 16g makes it possible to generate a straight stop when the stopper is in the standby position, this between the projecting element 15 and the protrusion 35b. Such a contact makes it possible to secure the maintenance of the stopper in the waiting position.
Avantageusement encore, la portion supérieure 16c et la première portion latérale 16a de la face périphérique 16 définissent entre elles une deuxième arête 16h. La présence de cette deuxième arête 16h permet de générer une butée franche lorsque le bouchon est en position de fermeture, ceci entre l'élément en saillie 15 et la protrusion 35c. Un tel contact permet de sécuriser le maintien du bouchon en position de fermeture. Also advantageously, the upper portion 16c and the first lateral portion 16a of the peripheral face 16 define between them a second edge 16h. The presence of this second ridge 16h makes it possible to generate a straight stop when the stopper is in the closed position, this between the projecting element 15 and the protrusion 35c. Such a contact makes it possible to secure the retention of the cap in the closed position.
Préférentiellement, l’élément en saillie 15 comprend une face distale 18 légèrement concave de sorte à épouser la surface externe du goulot 3. Cette forme concave permet de réduire l’encombrement et d’améliorer l’appui du pion 15 contre le goulot 3. Ladite face distale 18 est bordée par lesdites portions planes 16a, 16b, 16c et 16d. Preferably, the projecting element 15 comprises a distal face 18 which is slightly concave so as to match the external surface of the neck 3. This concave shape makes it possible to reduce the bulk and improve the support of the pin 15 against the neck 3. Said distal face 18 is bordered by said flat portions 16a, 16b, 16c and 16d.
Avantageusement, la première portion latérale 16a de la face périphérique 16 et la face distale 18 de l’élément en saillie 15 définissent entre elles une troisième arête 18a. Avantageusement encore, la portion inférieure 16b de la face périphérique 16 et la face distale 18 de l’élément en saillie 15 définissent entre elles une quatrième arête 18b. Préférentiellement, la portion supérieure 16c de la face périphérique 16 et la face distale 18 de l’élément en saillie 15 définissent entre elles une cinquième arête 18c. Préférentiellement encore, la deuxième portion latérale 16d de la face périphérique 16 et la face distale 18 de l’élément en saillie 15 définissent entre elles une sixième arête 18d. Advantageously, the first lateral portion 16a of the peripheral face 16 and the distal face 18 of the projecting element 15 define between them a third ridge 18a. Again advantageously, the lower portion 16b of the peripheral face 16 and the distal face 18 of the projecting element 15 define between them a fourth edge 18b. Preferably, the upper portion 16c of the peripheral face 16 and the distal face 18 of the projecting element 15 define between them a fifth edge 18c. Again preferably, the second lateral portion 16d of the peripheral face 16 and the distal face 18 of the projecting element 15 define between them a sixth edge 18d.
La présence d’arêtes sur le pion 15 permet de générer des contraintes et de sécuriser les différentes positions du bouchon 1 su le goulot 3. The presence of ridges on the pin 15 makes it possible to generate stresses and to secure the different positions of the stopper 1 on the neck 3.
Comme illustré aux figures 7 à 9, la présente invention concerne également un ensemble 100 comprenant un goulot 3 et un bouchon 1 tel que décrit ci-dessus. As illustrated in Figures 7 to 9, the present invention also relates to an assembly 100 comprising a neck 3 and a stopper 1 as described above.
