CA 2132258

The closure (2), for a jar (1) with a neck (3) for containing a product in a tamperproof manner, in particular a cosmetic, in the said jar, is manufactured by plastic bi-injection and includes a hook ring (5) fixed on the neck (3) of the jar in a practically undetachable manner, the said hook ring being made of a first plastic material, and a disk (8), forming a cover, made of a second plastic material and attached to the hook ring. The disk (8) has a means of traction (12), opening the jar necessitating the separation of the disk (8) from the hook ring (5). The ring (5) and the disk (8) are made of two different materials, selected so as to be incompatible to prevent them from bonding together by thermofusion, and the ring (5) is overmoulded at the edge (10) of the disk (8), the said edge (10) being in an annular groove (13) of the said ring.

L'élément de fermeture (2), pour un pot (1) muni d'un col (3) afin d'emprisonner de manière inviolable un produit, en particulier un produit cosmétique, dans ce pot, est réalisé par bi-injection de matière plastique et comprend une bague d'accrochage (5) fixée sur le col (3) du pot de manière pratiquement indémontable, cette bague d'accrochage étant réalisée en une première matière plastique, et un disque (8), formant couvercle, réalisé en une deuxième matière plastique et lié à la bague d'accrochage. Le disque (8) est muni d'un moyen de traction (12), l'ouverture du pot nécessitant de séparer le disque (8) de la bague d'accrochage (5). La bague (5) et le disque (8) sont réalisés en deux matières différentes, choisies de manière à être incompatibles pour qu'il ne s'établisse pas de liaison par thermofusion entre elles, et la bague (5) est surmoulée sur le bord (10) du disque (8), lequel bord (10) se trouve enserré dans une gorge annulaire (13) de ladite bague.
