Abstract
Description
La présente invention a pour objet un bouchon en matière synthétique équipé d'une bague d'inviolabilité.The present invention relates to a plastic cap fitted with a tamper-evident ring.
Pour de nombreux produits conditionnés dans des bidons, bouteilles ou flacons, il est nécessaire de réaliser un bouchage présentant un caractère inviolable avant la première ouverture, afin de garantir à l'acheteur la quantité et la qualité du contenu du récipient.For many products packaged in cans, bottles or flasks, it is necessary to make a stopper having an inviolable character before the first opening, in order to guarantee the buyer the quantity and the quality of the contents of the container.
Il est connu, pour remplir cette condition, d'associer à la base de la jupe du bouchon, une bague reliée à celle-ci par quelques pattes de faible résistance, destinées à venir prendre appui sous une collerette que présente le col du récipient, lorsque le bouchon est en position de fermeture du récipient.It is known, to fulfill this condition, to associate with the base of the skirt of the stopper, a ring connected to the latter by a few legs of low resistance, intended to come to bear under a flange presented by the neck of the container, when the cap is in the closed position of the container.
Lors de la première ouverture du récipient, correspondant à un déplacement axial du bouchon, la bague est retenue par la collerette, et les pattes de liaison entre la bague et le bouchon se déchirent, permettant le retrait de ce dernier. La première ouverture du récipient peut donc être visualisée immédiatement du fait de la désolidarisation entre la bague d'inviolabilité et le bouchon.When the container is opened for the first time, corresponding to an axial displacement of the stopper, the ring is retained by the flange, and the connecting tabs between the ring and the stopper tear, allowing the latter to be withdrawn. The first opening of the container can therefore be viewed immediately due to the separation between the tamper-evident ring and the cap.
Dans la mesure où le bouchon est réalisé en matière synthétique, il n'est pas possible de l'obtenir en une seule pièce, notamment lorsque l'on désire que le bouchon présente une partie en forme de capsule épousant le bord du col du récipient et pénétrant dans celui-ci pour assurer une bonne étanchéité, indispensable dans le cas du conditionnement de produits pharmaceutiques, par exemple.Insofar as the stopper is made of synthetic material, it is not possible to obtain it in one piece, in particular when it is desired that the stopper has a capsule-shaped part conforming to the edge of the neck of the container. and penetrating therein to ensure a good seal, essential in the case of packaging of pharmaceutical products, for example.
Les bouchons utilisés dans de telles applications sont souvent réalisés en trois pièces, à savoir: le bouchon proprement dit équipé de moyens d'accrochage sur le col du récipient, une capsule montée dans le fond du bouchon, et une pièce portant la bague d'inviolabilité, associée à l'extrémité ouverte de la jupe du bouchon.The caps used in such applications are often produced in three parts, namely: the cap itself equipped with attachment means on the neck of the container, a capsule mounted in the bottom of the cap, and a part carrying the ring. inviolability, associated with the open end of the cap skirt.
La demande de brevet français 2190687 concerne un bouchon à vis métallique comprenant, à proximité de l'extrémité inférieure de sa partie en forme de jupe cylindrique, un certain nombre de saillies vers l'extérieur, régulièrement réparties sur sa périphérie, et destinées à pénétrer dans des évidements complémentaires ménagés dans une bague d'inviolabilité en matière synthétique, comportant également un bourrelet périphérique venant prendre appui sous un collet ménagé sur le col du récipient à fermer.
La demande de brevet allemand DE 2331690 décrit un bouchon en matière synthétique équipé d'un bague d'inviolabilité, comprenant une première capsule destinée à obturer le col d'un récipient en étant fixée sur celui-ci par vissage et une seconde capsule de hauteur supérieure à celle de la première, destinée à être engagée sur celle-ci, et comportant, à son extrémité inférieure, une bague d'inviolabilité, la liaison en rotation entre les deux capsules étant réàttséé par des'nervu'rës et rainures complémentaires ménagées dans leurs parois en contact, c'est-à-dire sur la face extérieure de la capsule intérieure et sur la face intérieure de la capsule extérieure.German patent application DE 2331690 describes a plastic stopper fitted with a tamper-evident ring, comprising a first capsule intended to close the neck of a container by being fixed thereon by screwing and a second height capsule higher than that of the first, intended to be engaged on the latter, and comprising, at its lower end, a tamper-evident ring, the connection in rotation between the two capsules being readjusted by complementary nerve and grooves in their contacting walls, that is to say on the outer face of the inner capsule and on the inner face of the outer capsule.
La présente invention vise à remédier à ces inconvénients en fournissant un bouchon inviolable en matière synthétique, de structure simple.The present invention aims to remedy these drawbacks by providing a tamper-evident plastic stopper, of simple structure.
Ce bouchon, du type comprenant une capsule présentant un fond destiné à obturer l'ouverture du récipient, prolongé par une partie cylindrique dont la face interne est munie de moyens d'accrochage sur la paroi périphérique du col du récipient et dont la face externe présente des parties en saillie régulièrement réparties sur sa périphérie, et une bague d'inviolabilité solidaire d'une jupe cylindrique en matière synthétique ouverte à ses deux extrémités et dont le diamètre intérieur est sensiblement égal au diamètre extérieur de la capsule et comportant, dans sa face interne, des évidements, de forme complémentaire de celle des parties en saillie de la capsule, est caractérisé en ce que la jupe cylindrique portant la bague d'inviolabilité présente, à son extrémité opposée à la bague d'inviolabilité, un bord intérieur chanfreiné, entoure intégralement la face périphérique externe de la capsule, les parties en saillie sur la face externe de la partie cylindrique de la capsule et les évidements en saillie sur la face interne de la jupe cylindrique ayant la forme de nervures et de rainures longitudinales complémentaires et étant de longueur sensiblement égale, ces rainures longitudinales étant limitées par deux épaulements en saillie vers l'intérieur.This stopper, of the type comprising a capsule having a bottom intended to close the opening of the container, extended by a cylindrical part the internal face of which is provided with means for hooking on the peripheral wall of the neck of the container and the external face of which has protruding parts regularly distributed over its periphery, and a tamper-evident ring secured to a cylindrical skirt of synthetic material open at its two ends and whose internal diameter is substantially equal to the external diameter of the capsule and comprising, in its face internal, recesses, of shape complementary to that of the projecting parts of the capsule, is characterized in that the cylindrical skirt carrying the tamper-evident ring has, at its end opposite the tamper-evident ring, a chamfered inner edge, completely surrounds the outer peripheral face of the capsule, the protruding parts on the outer face of the cylindrical part of the capsule and recesses them ents projecting from the internal face of the cylindrical skirt having the shape of ribs and complementary longitudinal grooves and being of substantially equal length, these longitudinal grooves being limited by two shoulders projecting inwards.
Le montage du bouchon est réalisé par engagement de la capsule dans la jupe, par l'extrémité de celle-ci opposée à celle équipée de la bague d'inviolabilité.The mounting of the cap is carried out by engagement of the capsule in the skirt, by the end of the latter opposite to that equipped with the tamper-evident ring.
Un blocage axial de la capsule dans la jupe est obtenu par appui des extrémités des nervures de la capsule contre les épaulements de la jupe, et un blocage en rotation de la capsule et de la jupe est obtenu par complémentarité des nervures de la capsule et des rainures de la jupe.Axial locking of the capsule in the skirt is obtained by pressing the ends of the ribs of the capsule against the shoulders of the skirt, and rotationally locking of the capsule and the skirt is obtained by complementarity of the ribs of the capsule and the skirt grooves.
Ainsi, lors du premier débouchage, que la fixation du bouchon ait été réalisée par vissage ou encliquetage, la jupe et la capsule demeureront solidaires, et la jupe se détachera de la bague d'inviolabilité.Thus, during the first uncorking, whether the fixing of the stopper has been carried out by screwing or snap-fastening, the skirt and the capsule will remain integral, and the skirt will detach from the tamper-evident ring.
Ce bouchon présente par rapport à ceus existants, l'avantage d'une grande simplicité de réalisation puisque constitué par deux pièces seulement, tout en offrant d'excellentes qualités d'étanchéité et d'inviolabilité avant première ouverture.This stopper has, compared to existing ones, the advantage of great simplicity of construction since it consists of only two parts, while offering excellent sealing and tamper-evident qualities before first opening.
En outre, ce bouchon est extrêmement facile à manoeuvrer compte tenu de la surface importante de la jupe qui entoure le col du récipient. Enfin, le fait qu'une jupe entoure la capsule fixée sur le col du récipient empêche la déformation de cette dernière par ovalisation lors de sa manoeuvre.In addition, this cap is extremely easy to maneuver given the large surface area of the skirt which surrounds the neck of the container. Finally, the fact that a skirt surrounds the capsule fixed to the neck of the container prevents the latter from being deformed by ovalization during its operation.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce bouchon:
- Fig. 1 en est une vue en perspective éclatée;
- Fig. 2 correspond à deux demi-coupes longitudinales et à échelle agrandie de ce bouchon, respectivement, en position de fermeture, et en cours d'ouverture d'un récipient.
- Fig. 1 is an exploded perspective view;
- Fig. 2 corresponds to two longitudinal half-sections and on an enlarged scale of this plug, res pectively, in the closed position, and during the opening of a container.
Le bouchon représenté au dessin est constitué par deux éléments obtenus indépendamment l'un de l'autre à savoir une capsule (2) et une jupe (3) cylindrique engagée sur la capsule (2). La capsule (2) présente un fond (4) qui, destiné à venir obturer l'ouverture du col (5) du récipient à fermer, présente une double lèvre (6) autojointante, afin de rattraper les écarts de tolérance au niveau du col du récipient, et d'assurer un excellent contact avec celui-ci. Du fond (4) de la capsule (2) fait saillie une partie cylindrique (7) présentant, sur la face intérieure, un taraudage (8) destiné à coopérer avec un filetage (9) que présente le col (5) du récipient, pour réaliser la fixation sur ce dernier.The cap shown in the drawing consists of two elements obtained independently of each other, namely a capsule (2) and a cylindrical skirt (3) engaged on the capsule (2). The capsule (2) has a bottom (4) which, intended to seal the opening of the neck (5) of the container to be closed, has a double self-sealing lip (6), in order to make up for the tolerance differences at the level of the neck of the container, and to ensure excellent contact therewith. From the bottom (4) of the capsule (2) projects a cylindrical part (7) having, on the inner face, a thread (8) intended to cooperate with a thread (9) that has the neck (5) of the container, to secure it.
La partie cylindrique (7) présente, sur sa face externe, un certain nombre de nervures longitudinales (10).The cylindrical part (7) has, on its external face, a certain number of longitudinal ribs (10).
La jupe (3) cylindrique est équipée, de façon connue à son extrémité inférieure, d'une bague d'inviolabilité (12) destinée à venir prendre appui, en position de fermeture du récipient, sur la face inférieure d'une collerette (13), que présente le col (5) du récipient à fermer. La bague d'inviolabilité (12) est reliée au corps de la jupe (3) par des languettes (14) de faible résistance, pouvant être déchirées facilement.The cylindrical skirt (3) is equipped, in a known manner at its lower end, with a tamper-evident ring (12) intended to come to bear, in the closed position of the container, on the lower face of a flange (13 ), which has the neck (5) of the container to be closed. The tamper-evident ring (12) is connected to the body of the skirt (3) by tabs (14) of low resistance, which can be torn easily.
La jupe (3) est de longueur supérieure à celle de la capsule (2), et de diamètre intérieur sensiblement égal au diamètre extérieur de la capsule (2). La jupe (3) présente, à partir de son extrémité opposée à celle équipée de la bague d'inviolabilité (12), un certain nombre de rainures longitudinales (15), de longueur correspondant sensiblement à la longueur des nervures (10) que présente la capsule (2), la zone de la jupe (3) présentant les rainures étant limitées par deux épaulements, respectivement (16) et (17) faisant saillie vers l'intérieur de la jupe. En outre, l'extrémité de la jupe opposée à celle equipée de la bague d'inviolabilité (12) présente un bord intérieur (18) chanfreiné.The skirt (3) has a length greater than that of the capsule (2), and an internal diameter substantially equal to the external diameter of the capsule (2). The skirt (3) has, from its end opposite to that equipped with the tamper-evident ring (12), a certain number of longitudinal grooves (15), of length corresponding substantially to the length of the ribs (10) that presents the capsule (2), the area of the skirt (3) having the grooves being limited by two shoulders, respectively (16) and (17) projecting towards the inside of the skirt. In addition, the end of the skirt opposite to that fitted with the tamper-evident ring (12) has a chamfered inner edge (18).
La jupe (3) présente enfin, sur sa face externe, un certain nombre de nervures longitudinales (19) facilitant sa manipulation, notamment lors du vissage et du dévissage du bouchon sur le col (5) du récipient.The skirt (3) has finally, on its external face, a certain number of longitudinal ribs (19) facilitating its handling, in particular during the screwing and unscrewing of the cap on the neck (5) of the container.
D'un point de vue pratique, les deux pièces (2) et (3) étant obtenues indépendamment l'une de l'autre, il est procédé à leur montage par engagement de la capsule (2) dans la jupe (3) à partir de son extrémité opposée à celle équipée de la bague d'inviolabilité (12). Au cours de ce mouvement, les nervures (10) de la capsule (2) pénètrent dans les rainures (15) de la jupe (3). La complémentarité entre les nervures (10) et les rainures (15) assure le blocage en rotation de la jupe relativement à la capsule. En outre, les nervures (10) de la capsule (2) prennent appui sur les épaulements respectivement (16) et (17) de la jupe (3), évitant tout mouvement de translation de la capsule (2) relativement à la jupe (3).From a practical point of view, the two parts (2) and (3) being obtained independently of one another, it is proceeded to their assembly by engagement of the capsule (2) in the skirt (3) to from its end opposite to that fitted with the tamper-evident ring (12). During this movement, the ribs (10) of the capsule (2) penetrate into the grooves (15) of the skirt (3). The complementarity between the ribs (10) and the grooves (15) ensures the rotation blocking of the skirt relative to the capsule. In addition, the ribs (10) of the capsule (2) bear on the shoulders respectively (16) and (17) of the skirt (3), avoiding any translational movement of the capsule (2) relative to the skirt ( 3).
Après assemblage de la capsule (2) et de la jupe (3), le bouchon est mis en place sur un récipient et occupe, avant la première ouverture, la position représentée à la partie gauche de la fig. 2.After assembly of the capsule (2) and the skirt (3), the stopper is placed on a container and occupies, before the first opening, the position shown in the left part of FIG. 2.
Pour réaliser l'ouverture du récipient, il suffit d'exercer un mouvement de dévissage sur le bouchon, au cours duquel est réalisée la rupture des pattes (14) reliant la bague (12) et la jupe (3). Etant donné la solidarisation en rotation de la capsule (2) et de la jupe (3), le mouvement de rotation exercé sur la jupe (3) provoque le dévissage de la capsule (2), et par suite son dégagement relativement au col du récipient (5), comme montré à la partie droite de la fig. 2.To make the opening of the container, it suffices to exert a movement of unscrewing on the stopper, during which the tabs (14) connecting the ring (12) and the skirt (3) are broken. Given the joining in rotation of the capsule (2) and the skirt (3), the rotational movement exerted on the skirt (3) causes the unscrewing of the capsule (2), and consequently its release relative to the neck of the container (5), as shown on the right side of fig. 2.
Après première ouverture, il sera possible de réaliser une nouvelle fermeture étanche du récipient en procédant à la mise en place du bouchon sur le col du récipient par vissage.After first opening, it will be possible to make a new tight closure of the container by proceeding with the fitting of the cap on the neck of the container by screwing.
Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un bouchon en matière synthétique de conception simple, réalisé à partir de deux pièces seulement, possédant d'excellentes caractéristiques d'étanchéité et d'inviolabilité avant première ouverture.As is clear from the above, the invention brings a great improvement to the existing technique by providing a plastic plug of simple design, made from only two parts, having excellent sealing and tamper-evident characteristics. before first opening.
