ABSTRACT:
The closure element (2) for a pot (1) equipped with a neck (3) in order to confine a product, particularly a cosmetic product, in this pot in a tamperproof manner, is produced by dual-injection of plastic and comprises a fastening ring (5) fixed onto the neck (3) of the pot in a practically non-removable manner, this fastening ring being produced from a first plastic, and a disc (8) forming a lid, produced from a second plastic and connected to the fastening ring. The disc (8) is equipped with a pull means (12), it being necessary to separate the disc (8) from the fastening ring (5) in order to open the pot. The ring (5) and the disc (8) are produced from two different materials which are chosen to be incompatible so that no connection becomes established between them by thermofusion, and the ring (5) is over-moulded over the edge (10) of the disc (8), which edge (10) is trapped in an annular groove (13) in the said ring.
