JOINT D'ETANCHEITE
Pour assurer l'étanchéité entre un récipient et un capuchon fixé sur ce récipient, il est connu de disposer dans le fond du Ca- puchon un joint qui, lorsque le capuchon est en place, est serré entre le fond de ce dernier et la tranche du récipient. Mais l'étanchéité obtenue n'est pas certaine. En effet, la tranche du récipient a généralement une surface irrégulière, de sorte que le joint n'est pas pressé de manière uniforme sur cette tranche; par ailleurs, lorsque le capuchon est en matière plastique, le diamètre de ce capuchon n'a pas une valeur précise et peut, dans certaines limites, varier. Pour remédier à ce défaut, on a proposé des joints complexes constitués par un corps en matière plastique revêtu d'une pellicule d'aluminium. Mais ces joints sont coûteux.SEALING
To ensure the seal between a container and a cap fixed to this container, it is known to have in the bottom of the cap a seal which, when the cap is in place, is clamped between the bottom of the latter and the edge of the container. But the seal obtained is not certain. Indeed, the edge of the container generally has an irregular surface, so that the seal is not pressed uniformly on this edge; moreover, when the cap is made of plastic, the diameter of this cap does not have a precise value and can, within certain limits, vary. To remedy this defect, complex seals have been proposed consisting of a plastic body coated with an aluminum film. But these seals are expensive.
La présente invention a pour objet un joint d'étanchéité pour récipient qui est de construction simple et assure cependant une é tanchéité certaine. The subject of the present invention is a seal for a container which is of simple construction and yet ensures a certain seal.
Le joint selon l'invention est caractérisé en ce qu'il comporte deux lèvres périphériques tronconiques superposées, la lèvre supérieure ayant une conicité plus faible et un diamètre extérieur plus grand que la lèvre inférieure, et en ce que l'ensemble des deux lèvres est relié à la partie centrale du joint par une zone relativement souple. The seal according to the invention is characterized in that it comprises two superimposed frustoconical peripheral lips, the upper lip having a smaller conicity and a larger outside diameter than the lower lip, and in that the assembly of the two lips is connected to the central part of the joint by a relatively flexible area.
Pour un récipient donné, on utilise un joint dont la livre supérieure a un diamètre compris entre le diamètre extérieur et le diamètre intérieur du récipient et dont la lèvre inférieure a un diamètre inférieur au diamètre intérieur de ce répicient. For a given container, a seal is used whose upper pound has a diameter between the outside diameter and the inside diameter of the container and whose lower lip has a diameter less than the inside diameter of this container.
Lorsqu'un capuchon est fixé sur le récipient, par exemple par vissage, le fond de ce capuchon pousse sur la partie centrale du joint. La lèvre supérieure pivote de manière à venir reposer à plat sur la tranche du récipient. Ce faisant, elle entratne la lèvre inférieure qui vient se plaquer sur la face intérieure de la paroi du récipient et assure l'étanchéité. Celle-ci est donc obtenue essentiellement par la lèvre inférieure, la lèvre supérieure n'étant qu'une lèvre de commande qui amène la lèvre inférieure en position d'étanchéité. When a cap is attached to the container, for example by screwing, the bottom of this cap pushes on the central part of the seal. The upper lip pivots so as to come to rest flat on the edge of the container. In doing so, it drives the lower lip which is pressed against the inner face of the wall of the container and ensures sealing. This is therefore obtained essentially by the lower lip, the upper lip being only a control lip which brings the lower lip into the sealing position.
L'ensemble des deux lèvres peut Entre relie à la partie centrale du joint par une zone amincie. The assembly of the two lips can be connected to the central part of the joint by a thinned zone.
Le joint selon l'invention convient en particulier pour des récipients destinés à contenir un produit volatil. The seal according to the invention is particularly suitable for containers intended to contain a volatile product.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du joint selon l'invention, avec référence au dessin annexé dans lequel
La Figure 1 est une vue en coupe transversale du joint;
La Figure 2 est une vue semblable à la Figure 1, le joint étant serré;
La Figure 3 en est une vue en plan.An embodiment of the joint according to the invention has been described below, by way of nonlimiting example, with reference to the appended drawing in which
Figure 1 is a cross-sectional view of the seal;
Figure 2 is a view similar to Figure 1, the joint being tight;
Figure 3 is a plan view.
Tel qu'il est représenté au dessin, le joint 1 selon l'inven tion a une forme circulaire et est destine à assurer l'étanchéité entre un récipient 2 et un capuchon 3 vissé sur le récipient 2. As shown in the drawing, the seal 1 according to the invention has a circular shape and is intended to seal between a container 2 and a cap 3 screwed onto the container 2.
Le joint 1 comporte une partie centrale sensiblement plane 4 qui est prolongée à sa périphérie par deux lèves minces 5 et 6, lten > semble de ces deux lèves étant réuni à la partie 3 par une zone annulaire amincie 7. a partie 4 est munie en son centre d'une dépression 8 dans laquelle peut s'engager un téton de centrage 9 du capuchon 3. The seal 1 comprises a substantially flat central part 4 which is extended at its periphery by two thin lifts 5 and 6, lten> seems to be of these two lifts being joined to part 3 by a thinned annular zone 7. a part 4 is provided with its center of a depression 8 into which a centering stud 9 of the cap 3 can engage.
La livre supérieure S a un diamètre extérieur qui est un peu inférieur au diamètre extérieur du récipient 2. Elle est tronconique, sa face inférieure Sa faisant un angle de l'ordre de 10 à 150 avec l'axe du joint. La lèvre inférieure 6, à l'état libre, a un diamètre extérieur plus faible que le diamètre intérieur du récipient 2. Elle est également tronconique, mais sa conicité est plus grande que celle de la lèvre 4. The upper book S has an outside diameter which is slightly less than the outside diameter of the container 2. It is frustoconical, its lower face Sa making an angle of the order of 10 to 150 with the axis of the joint. The lower lip 6, in the free state, has a smaller outside diameter than the inside diameter of the container 2. It is also frustoconical, but its taper is greater than that of the lip 4.
Lorsqu'on visse le capuchon 3 sur le récipient 2, le fond de ce capuchon vient pousser sur la partie centrale 4 du joint 1 dont la levre S est en appui sur la tranche du récipient 2. Sous l'effet de cette poussée, l'ensemble des deux lèvres S et 6 pivote vers l'ex térieur au droit de la portion amincie 7 et la lèvre 6 vient se plaquer sur la face interne de la paroi du récipient 2, ce qui assure l'etanchéité. When the cap 3 is screwed onto the container 2, the bottom of this cap pushes on the central part 4 of the seal 1, the lip S of which rests on the edge of the container 2. Under the effect of this push, the 'assembly of the two lips S and 6 pivots outwards to the right of the thinned portion 7 and the lip 6 is pressed against the internal face of the wall of the container 2, which ensures sealing.
Il va de soi que la présente invention ne doit pas etre considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
