Abstract

Tape (3) is placed around cap (2), rests on fixed section (1) on one side and has superficial boss (5) on other side. Bosses are linking braces with contour (8) of cap that receive peripheral boss (10) on sliding skirt (9) that interlock with ribs (11). That forms impenetrable solid assembly that can only be altered by rotation.

Description

La présente invention concerne un dispositif dans les bouchons thermoplastiques du type "tirer-pousser", c'est-à-dire ceux réalisés au moyen de deux pièces, l'une mobile pouvant coulisser sur une autre pièce fixe dans un mouvement de va-et-vient entre certaines limites qui déterminent la bonne ouverture et la fermeture du bouchon concerné.The present invention relates to a device in plugs "pull-push" type thermoplastics, that is to say those made using two parts, one of which can slide on another part fixed in a back and forth movement between certain limits which determine the correct opening and closing of the cap concerned.

Ces bouchons sont accompagnés dans leur commercialisation d'une troisième pièce, faisant fonction de scellement de garantie, ajoutée de façon tout à fait indépendante par rapport aux pièces constituant le bouchon proprement dit.These caps are accompanied in their marketing of a third part, acting as a guarantee seal, added so completely independent from the parts making up the stopper well said.

L'invention de référence évite ladite troisième pièce, composante des solutions antérieures, en proposant un agencement simple à réaliser qui simplifie la structure sans dégrader aucune des fonctions de garantie d'inviolabilité réalisées avec la pièce mobile.The reference invention avoids said third part, a component of previous solutions, by proposing a simple arrangement to realize which simplifies the structure without degrading any of the warranty functions inviolability made with the moving part.

A cette fin, la solution selon l'invention propose que le couvercle mobile lui-même, qui se déplace en va-et-vient, comporte une bande périphérique qui, grâce à ses caractéristiques constructives, est montée sur la pièce fixe et s'y adapte en ajustement parfait.To this end, the solution according to the invention proposes that the movable cover itself, which moves back and forth, has a peripheral band which, thanks to its constructive characteristics, is mounted on the fixed part and adapts to it in perfect fit.

Selon l'invention, autour de la pièce mobile, ou couvercle, est formée d'une seule pièce avec elle, une bande, constituant une jupe périphérique, reposant d'un côté sur la pièce fixe, tandis que de l'autre côté elle comporte des saillies superficielles prévues pour constituer sur la bordure même de la bande des points de jonction correspondants réalisant des entretoises de liaison avec le contour de la pièce mobile qui, à son tour, reçoit sur sa jupe coulissante des saillies périphériques qui engrènent avec une succession de nervures prévues à l'intérieur d'une jupe faisant saillie de la pièce fixe pour réaliser un ensemble monobloc impénétrable, qui ne peut être altéré que par une rotation.According to the invention, around the moving part, or cover, is formed of a single piece with it, a band, constituting a peripheral skirt, resting on one side on the fixed part, while on the other side it has superficial projections provided to constitute on the very edge of the strip of corresponding junction points making spacers of connection with the outline of the moving part which, in turn, receives on its skirt sliding peripheral projections which mesh with a succession of ribs provided inside a skirt projecting from the fixed part for create an impenetrable one-piece assembly, which can only be altered by a rotation.

L'invention est décrite ci-après en relation avec les figures annexées.

  • La figure 1 est une vue en élévation du dispositif d'inviolabilité selon l'invention ;
  • La figure 2 est une vue en élévation en coupe qui montre les particularités constructives et fonctionnelles du bouchon selon l'invention;
  • La figure 3 représente l'assemblage bouchon-couvercle dépourvu de la bande de scellement incorporée selon l'invention.
  • La figure 4 est une vue en élévation en coupe du bouchon en position d'ouverture.
  • La figure 5 est une vue en plan du dispositif selon l'invention.
    • The invention is described below in relation to the attached figures.
  • Figure 1 is an elevational view of the tamper-evident device according to the invention;
  • Figure 2 is an elevational sectional view showing the constructive and functional features of the plug according to the invention;
  • FIG. 3 represents the cap-cover assembly devoid of the incorporated sealing strip according to the invention.
  • Figure 4 is an elevational sectional view of the plug in the open position.
  • Figure 5 is a plan view of the device according to the invention.

    • Il existe une variété de bouchons thermoplastiques pour des récipients, consistant en une pièce fixe faisant office de capuchon 1 sur laquelle se déplace, entre deux limites correspondant à l'ouverture et à la fermeture, sous l'effet de poussée ou de traction, une pièce mobile, faisant office de couvercle 2, qui garantie l'inviolabilité du bouchon au moyen de l'adjonction d'une troisième pièce faisant office de scellement.There are a variety of thermoplastic caps for containers, consisting of a fixed part acting as a cap 1 on which is moves, between two limits corresponding to opening and closing, under the effect of push or pull, a moving part, acting as cover 2, which guarantees the inviolability of the cap by means of the addition of a third part serving as a seal.

    La solution selon la présente invention permet d'éviter cette troisième pièce par le fait qu'elle prévoit que le couvercle 2 comporte autour de lui et d'une seule pièce avec lui, la bande de scellement 3 constituant une jupe 4 périphérique qui, d'une part repose sur la partie supérieure du capuchon 1 tandis que, d'autre part, elle porte des saillies superficielles 5 régulièrement réparties, qui avancent par rapport à la bordure 6 de la bande 3, elle-même sous forme d'entretoises de liaison 7 avec le contour 8 du couvercle 2 pour constituer des points de faiblesse au déchirement. The solution according to the present invention makes it possible to avoid this third part by the fact that it provides for the cover 2 to have around it and a single piece with it, the sealing strip 3 constituting a skirt 4 device which, on the one hand rests on the upper part of the cap 1 while, on the other hand, it has superficial projections 5 regularly distributed, which advance with respect to the edge 6 of the strip 3, itself in the form of connecting spacers 7 with the contour 8 of the cover 2 for constitute points of weakness in tearing.

    Sur la jupe coulissante 9 du couvercle 2 sont constituées des saillies 10 en prise avec une succession de nervures 11 prévues à leur tour à l'intérieur de la jupe 12 qui dépasse de la partie supérieure du capuchon 1.On the sliding skirt 9 of the cover 2 are formed projections 10 in taken with a succession of ribs 11 in turn provided inside the skirt 12 which projects from the upper part of the cap 1.

    Toutes ces caractéristiques telles que décrites concourent à constituer un ensemble monobloc et inaccessible garantissant l'inviolabilité du récipient.All these characteristics as described combine to constitute a monobloc and inaccessible assembly guaranteeing the inviolability of the container.

    Afin d'utiliser le récipient, une rotation de la bande de scellement 3 par rapport au couvercle, qui est fixe en rotation grâce aux saillies 10 engrenant dans les nervures 11, permet de déchirer les entretoises 7. Le récipient est alors débouché par traction vers le haut de la pièce mobile 2 qui se déplace jusqu'à une butée. Il est refermé par pression sur cette même pièce vers le bas jusqu'à une autre butée.In order to use the container, a rotation of the sealing strip 3 by relative to the cover, which is fixed in rotation thanks to the projections 10 meshing in the ribs 11, tears the spacers 7. The container is then outlet by pulling upwards the moving part 2 which moves up to a stop. It is closed by pressure on this same piece towards the down to another stop.

    L'enlèvement de la bande 3 permet de révéler que le flacon a été ouvert.Removing the strip 3 reveals that the bottle has been opened.
