The invention relates to a method for at least partially peeling off or separating a sealing film (14) sealed onto the rim (11) of the neck (3) of a receptacle, container, bottle (1) or the like. Said neck comprises an rim (11) having a circular sealing area (12), an external thread (4) and a center axis (5). A screw cap (7) having an internal thread (6) mating the external thread (4) is screwed onto the external thread (4) of the sealed neck (3), and screwed off at a chosen later time. When the screw cap (7) is screwed off from the neck (3), the sealing film (14) is at least partially peeled off by the screw cap (7) from the external circumference of the rim (11) of the neck (3) radially inwards and gradually towards the center axis (5) and is then lifted off from the rim (11).
Procédé permettant de détacher ou de séparer au moins partiellement une pellicule d'étanchéité (14) scellée sur le bord (11) à surface de scellage annulaire (12) du goulot (3), possédant un filetage externe (4) et un axe médian (5) d'un récipient, d'un flacon, d'une bouteille (1) ou analogue. Un bouchon fileté (7) est vissé sur le filetage externe (4) du goulot scellé (3), ledit bouchon possédant un filetage interne (6) correspondant au filetage externe (4), puis il est dévissé à un moment ultérieur choisi. Lorsque le bouchon fileté (7) est dévissé du goulot (3), la pellicule d'étanchéité (14) est au moins partiellement détachée, par le bouchon fileté (7), de la périphérie externe du bord (11) du goulot (3) radialement vers l'intérieur et graduellement vers l'axe médian (5), puis soulevée du bord (11).
