The invention relates to a cap (40) with sealing disk which can be positioned on, and notably screwed onto, the opening of a container (10). The sealing disk consists of several layers. The upper layers (24) are designed to remain in the cap when the container is opened while the lower layers (21, 22, 23) are sealed to the opening of the container. The upper layers can be used to reclose the container and are not glued in the screw cap. When the container is opened for the first time the upper layers are lifted vertically upwards by the lower layers, which prevents damage to the top side of said lower layers.
Un bouchon (40) muni d'un disque d'étanchéité est appliqué, plus particulièrement, vissé, sur l'ouverture d'un récipient (10). Le disque d'étanchéité est formé de plusieurs couches, les couches supérieures (24) restant dans le bouchon, lors d'une ouverture, et les couches inférieures (21, 22, 23) étant scellées sur l'ouverture du récipient. Les couches supérieures peuvent être utilisées pour refermer le récipient ; elles ne sont pas collées sur le bouchon fileté. Lorsque le récipient est ouvert pour la première fois, elles se détachent des couches inférieures et se soulèvent verticalement vers le haut, supprimant ainsi tout risque d'endommager la partie supérieure des couches inférieures.
