Description

La présente invention concerne un dispositif pour l'obturation étanche d'un récipient à col fileté équipé d'un bouchon.The present invention relates to a device for obturation sealed from a threaded neck container fitted with a cap.

Dans les modes de bouchage traditionnels, après conditionnement du produit dans le récipient, le col est obturé de façon hermétique par un opercule qui est susceptible d'être enlevé totalement ou partiellement lors de la première ouverture.In traditional capping methods, after packaging of the product in the container, the neck is hermetically sealed with a cover that can be removed completely or partially during the first opening.

La fermeture du récipient est généralement complétée par un bouchon vissé ou encliqueté sur le col de manière amovible en enfermant l'opercule. L'opercule est donc destiné à préserver le produit de toute pollution, contamination ou dégradation en l'isolant de l'environnement extérieur lors du stockage de longue durée.The closure of the container is generally supplemented by a plug screwed or snapped onto the collar removably by enclosing the cap. The cover is therefore intended to preserve the product from any pollution, contamination or degradation by isolating it from the environment outdoor during long term storage.

En outre, cet opercule doit offrir au consommateur un mode d'ouverture facile en étant aisément et rapidement séparable du col du récipient à la première ouverture.In addition, this cover must offer the consumer a mode easy to open by being easily and quickly separable from the neck of the container at first opening.

Ce double objectif conduit à réaliser des opercules de structure complexe dont le prix de revient est élevé et dont la pose est délicate et contraignante.This double objective leads to producing structural lids complex whose cost price is high and whose installation is delicate and binding.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante en supprimant cet opercule ou tout au moins en réduisant ses fonctions de façon à simplifier sa structure.The object of the present invention is to solve these problems techniques satisfactorily by removing this seal or any at least by reducing its functions so as to simplify its structure.

Ce but est atteint selon l'invention au moyen d'un dispositif, caractérisé en ce qu'il comprend une capsule au moins partiellement amovible destinée à être fixée directement sur ledit col C ou sur un opercule P préalablement scellé sur ledit col et qui porte une collerette périphérique pourvue d'une part d'une bague intérieure de préhension et d'arrachage et, d'autre part de languettes radiales extérieures de retenue dans le bouchon.This object is achieved according to the invention by means of a device, characterized in that it comprises an at least partially capsule removable intended to be fixed directly on said collar C or on a seal P previously sealed on said collar and which carries a collar peripheral provided on the one hand with an internal gripping ring and and, on the other hand, external radial retaining tabs in the cap.

Selon une caractéristique avantageuse, ladite bague comporte au moins une patte flexible formant charnière de liaison avec ladite collerette.According to an advantageous characteristic, said ring comprises at least one flexible tab forming a hinge for connection with said collar.

Selon une autre caractéristique, ladite bague est constituée d'un anneau libre en boucle ouverte ou fermée.According to another characteristic, said ring consists of a free ring in open or closed loop.

Selon encore une autre caractéristique, la partie radialement extérieure de ladite patte porte un poinçon assurant le percement de la capsule et/ou de l'opercule P par traction sur la bague. According to yet another characteristic, the radially outer of said tab carries a punch ensuring the piercing of the capsule and / or cover P by pulling on the ring.

Selon un premier mode de réalisation, ladite capsule est formée d'un disque plein pourvu, sur sa face inférieure, d'une rainure de fragilisation délimitant au centre de la collerette une pastille séparable dont le diamètre est supérieur à celui de la bague.According to a first embodiment, said capsule is formed of a solid disc provided on its underside with a groove of embrittlement delimiting in the center of the collar a separable patch whose diameter is greater than that of the ring.

Selon une variante particulière, la pastille centrale séparable est rendue solidaire de l'opercule.According to a particular variant, the separable central patch is made integral with the cover.

De préférence, ladite bague est constituée d'un anneau libre en boucle ouverte s'étendant au repos parallèlement au disque.Preferably, said ring consists of a free ring in open loop extending at rest parallel to the disc.

Selon une variante spécifique, la collerette périphérique délimite un logement cylindrique renfermant la bague au repos.According to a specific variant, the peripheral flange delimits a cylindrical housing enclosing the ring at rest.

Selon un autre mode de réalisation, la capsule est ajourée et la collerette est solidaire d'un opercule.According to another embodiment, the capsule is perforated and the collar is secured to a cover.

Selon une autre caractéristique, un espace libre intercalaire est ménagé entre la bague et la face supérieure de l'opercule.According to another characteristic, an intermediate free space is formed between the ring and the upper face of the cover.

Selon une variante, ladite bague est reliée radialement à la collerette au moyen de pontets susceptibles d'être rompus par traction sur ladite bague.According to a variant, said ring is connected radially to the collar by means of bridges which can be broken by traction on said ring.

Selon une autre variante, ladite collerette comprend deux nervures concentriques respectivement extérieure et intérieure délimitant enter elles une gorge.According to another variant, said collar comprises two concentric outer and inner ribs respectively delimiting enter them a throat.

De préférence, le fond de ladite gorge est pourvue d'une ligne de fragilisation permettant la séparation des deux nervures par traction sur la bague.Preferably, the bottom of said groove is provided with a line of embrittlement allowing the separation of the two ribs by traction on the ring.

Le dispositif de l'invention permet d'obtenir une étanchéité parfaite du récipient au moyen d'éléments d'obturation simples et complémentaires.The device of the invention makes it possible to obtain a seal perfect container by means of simple and complementary sealing elements.

L'ouverture du récipient s'effectue de façon aisée et rapide au moyen de la bague de préhension qui est légère et ergonomique et ne présente qu'un encombrement très réduit à l'intérieur du bouchon.The container is opened quickly and easily means of the grip ring which is light and ergonomic and does not has a very small footprint inside the cap.

Le dispositif de l'invention peut même, le cas échéant, se substituer à l'opercule tout en offrant conjointement une étanchéité renforcée et un mode d'ouverture plus souple et plus efficace.The device of the invention can even, if necessary, be replace the seal while simultaneously providing a seal reinforced and a more flexible and efficient opening mode.

L'invention sera mieux comprise à la lecture de la description qui va suivre en référence aux dessins, sur lesquels :

    • The invention will be better understood on reading the description which follows with reference to the drawings, in which:
  • FIGS. 1A, 1B and 1C represent views from above, in section and in perspective, of a first embodiment of the device of the invention.
  • FIGS. 2A, 2B and 2C show respectively views from above, in section and in perspective of a second embodiment of the device of the invention.
  • FIGS. 3A, 3B and 3C represent views from above respectively, in section and in perspective of a third embodiment of the device of the invention.
  • FIGS. 4A, 4B and 4C represent views from above respectively, in section and in perspective of a fourth embodiment of the device of the invention.

    • Le dispositif représenté sur les figures est destiné à assurer l'obturation étanche d'un récipient R à col fileté C susceptible d'être équipé d'un bouchon (non représenté).The device shown in the figures is intended to ensure sealing a container R with a threaded neck C capable of being fitted with a plug (not shown).

    Ce dispositif comprend une capsule amovible 1 fixée soit directement sur le col C comme cela est possible avec le mode de réalisation des figures 1A à 1C, soit sur un opercule P préalablement scellé sur ledit col.This device comprises a removable capsule 1 fixed either directly on the C-neck as is possible with the mode of embodiment of FIGS. 1A to 1C, either on a cover P beforehand sealed on said collar.

    La capsule 1 porte une collerette périphérique 14 pourvue, d'une part d'une bague intérieure 2 de préhension et d'arrachage et d'autre part, de languettes radiales extérieures et périphériques 11 de retenue dans le bouchon. Les languettes 11 sont aptes à coopérer avec des saillies ménagées sur la paroi latérale interne du bouchon derrière lesquelles elles viennent se bloquer temporairement par déformation élastique. Ces saillies sont, par exemple, constituées des filets permettant le vissage du bouchon sur le col.The capsule 1 carries a peripheral flange 14 provided, on the one hand, an inner ring 2 for gripping and tearing off, and on the other hand, external and peripheral radial tongues 11 of retained in the cap. The tongues 11 are able to cooperate with protrusions on the inner side wall of the plug behind which they temporarily block by deformation elastic. These projections are, for example, made up of threads allowing screwing the cap onto the neck.

    La bague 2 comporte au moins une patte flexible 12 formant charnière de liaison avec la capsule 1.The ring 2 has at least one flexible tab 12 forming hinge connecting with the capsule 1.

    Dans le mode de réalisation des figures 1A, 1B et 1C, la capsule 1 est formée d'un disque plein pourvu sur sa face inférieure d'une rainure 10 de fragilisation délimitant au centre de la collerette 14, une pastille séparable 1a. Le cas échéant, cette pastille 1a peut être rendue solidaire (par exemple par scellage) d'un opercule P. Le diamètre de cette pastille est supérieur à celui de la bague 2 de telle sorte qu'un effort de traction exercé sur ladite bague puisse détacher la pastille 1a et déchirer ou décoller l'opercule P, s'il existe, de façon à permettre l'ouverture du récipient R.In the embodiment of FIGS. 1A, 1B and 1C, the capsule 1 is formed of a solid disc provided on its underside with a weakening groove 10 defining at the center of the collar 14, a separable tablet 1a. If necessary, this tablet 1a can be returned secured (for example by sealing) with a cover P. The diameter of this disc is greater than that of ring 2 so that an effort of traction exerted on said ring can detach the patch 1a and tear or peel the cover P, if it exists, so as to allow the opening of the container R.

    La bague 2 est ici constituée d'un anneau libre en boucle ouverte s'étendant au repos dans un plan parallèle au disque et rattaché à ce dernier par deux pattes flexibles 12a, 12b coudées à 90° et permettant son déploiement vers le haut.Ring 2 here consists of a free loop ring open extending at rest in a plane parallel to the disc and attached to the latter by two flexible legs 12a, 12b bent at 90 ° and allowing its deployment upwards.

    La collerette périphérique 14 délimite latéralement un logement cylindrique pour recevoir la bague 2 au repos dans un plan perpendiculairement à l'axe du col C. A cet effet, la hauteur de la collerette 14 est supérieure ou égale à l'épaisseur de la bague 2 de telle sorte que son bord supérieur puisse venir en butée contre le fond du bouchon dans la position finale de vissage sur le col C.The peripheral flange 14 laterally delimits a housing cylindrical to receive the ring 2 at rest in a plane perpendicularly to the axis of the neck C. For this purpose, the height of the collar 14 is greater than or equal to the thickness of the ring 2 so that its upper edge can come into abutment against the bottom of the plug in the final screwing position on collar C.

    Dans le mode de réalisation des figures 2A, 2B et 2C, la capsule 1 est ajourée et la collerette périphérique 14 est solidaire d'un opercule P formant un voile central.In the embodiment of FIGS. 2A, 2B and 2C, the capsule 1 is perforated and the peripheral flange 14 is secured to a lid P forming a central veil.

    Ce mode de réalisation est nécessairement associé à la présence d'un opercule P à la différence du mode de réalisation des figures 1A, 1B et 1C qui peut s'en affranchir.This embodiment is necessarily associated with the presence of a cover P unlike the embodiment of the Figures 1A, 1B and 1C which can overcome them.

    La collerette 14 est rendue solidaire, par exemple par scellage ou collage, du pourtour de l'opercule P et de préférence au droit du rebord du col C. Toutefois, il est nécessaire, dans un souci d'efficacité, que la force de liaison entre la collerette périphérique 14 et l'opercule P soit supérieure à la force de liaison entre l'opercule et le rebord du col C. La pose de la capsule 1 sur le col C ménage un espace libre intercalaire 20 entre la face inférieure de la bague 2 et la face supérieure de l'opercule P pour permettre la prise de l'anneau.The collar 14 is made integral, for example by sealing or bonding, around the perimeter of the cover P and preferably at the right of the rim of the C-neck. However, for the sake of efficiency, that the bonding force between the peripheral flange 14 and the cover P is greater than the bonding force between the lid and the rim of the neck C. The installation of the capsule 1 on the collar C saves an intermediate space 20 between the lower face of the ring 2 and the upper face of the cover P to allow the setting of the ring.

    La bague 2 est ici constituée d'un anneau plat en boucle fermée qui s'étend au centre et de préférence dans le plan de la face supérieure de la capsule 1 en étant relié radialement à la collerette 14 au moyen de pontets 15. Les pontets 15 sont susceptibles d'être rompus par traction sur l'anneau.Ring 2 here consists of a flat loop ring closed which extends in the center and preferably in the plane of the face upper part of the capsule 1 while being connected radially to the collar 14 to the means of bridges 15. The bridges 15 are liable to be broken by pull on the ring.

    Les languettes 11 sont réalisées ici dans le prolongement radial des pontets 15.The tongues 11 are produced here in the extension radial of the bridges 15.

    Avec ce mode de réalisation, l'ouverture du récipient R s'effectue, en exerçant tout d'abord un effort de traction vertical sur l'anneau pour rompre les pontets 15 et dégager la bague 2 qui reste néanmoins attachée à la collerette 14 par la patte flexible 12.With this embodiment, the opening of the container R is carried out by first exerting a vertical tensile force on the ring to break the bridges 15 and release the ring 2 which remains nevertheless attached to the flange 14 by the flexible tab 12.

    Une fois l'anneau libéré et déployé, une nouvelle traction verticale provoquera le décollement progressif de l'opercule P du rebord du col C, le pourtour de l'opercule restant attaché à la collerette 14.Once the ring released and deployed, a new traction vertical will cause gradual detachment of the lid P from the edge of the neck C, the periphery of the cover remaining attached to the collar 14.

    Dans le mode de réalisation des figures 3A, 3B et 3C, la capsule 1 est encore ajourée et la bague 2 s'étend à l'état libre en position inclinée vers le haut (voir figure 3B).In the embodiment of FIGS. 3A, 3B and 3C, the capsule 1 is still perforated and the ring 2 extends in the free state in tilted up position (see Figure 3B).

    Toutefois, lors de la mise en place dans le bouchon, la bague 2 est rabattue sous contraintes dans un plan parallèle à celui de l'opercule P. Ainsi, à l'ouverture du bouchon, la bague 2 peut se déployer automatiquement en offrant un espace libre 20 pour la prise de l'anneau.However, when placing in the cap, the ring 2 is folded under constraints in a plane parallel to that of the cover P. Thus, when the cap is opened, the ring 2 can deploy automatically by providing a free space 20 for the grip of the ring.

    La partie radialement extérieure de la patte 12 porte un poinçon 13 assurant le percement de l'opercule P et/ou de la capsule lors du pivotement de la bague sous traction.The radially outer part of the tab 12 carries a punch 13 ensuring the piercing of the seal P and / or the capsule during pivoting of the ring under tension.

    La collerette 14 comprend ici deux nervures concentriques respectivement extérieure 14a et intérieure 14b délimitant entre elles une gorge 16. La gorge 16 est pourvue d'une ligne de fragilisation 17 ou de pontets (variante non représentée) permettant la séparation des deux nervures par traction sur la bague 2.The collar 14 here comprises two concentric ribs respectively exterior 14a and interior 14b delimiting between them a groove 16. The groove 16 is provided with a weakening line 17 or bridges (variant not shown) allowing the separation of the two ribs by pulling on the ring 2.

    Dans ce cas, la nervure extérieure 14a de la collerette 14 reste attachée au pourtour de l'opercule P et au rebord du col C après déchirure circulaire de l'opercule.In this case, the outer rib 14a of the flange 14 remains attached to the periphery of the lid P and to the edge of the collar C after circular tear in the cover.

    Le mode de réalisation des figures 4A, 4B et 4C est à rapprocher de celui des figures 1A, 1B et 1C mais la capsule comporte ici une partie centrale ajourée.The embodiment of FIGS. 4A, 4B and 4C is to approximate to that of FIGS. 1A, 1B and 1C but the capsule comprises here an openwork central part.

    Dans ce cas, la traction sur la bague 2 provoque le décollement de toute la capsule 1 avec l'opercule P du rebord du col C (voir figure 4C) et non plus la seule séparation de la pastille pleine 1a avec la partie associée de l'opercule P (voir figure 1B).In this case, the traction on the ring 2 causes the detachment of the entire capsule 1 with the lid P of the rim of the neck C (see Figure 4C) and no longer the only separation of the solid tablet 1a with the associated part of the cover P (see Figure 1B).
