Abstract

La présente invention concerne un système permettant de fermer un récipient avec un dispositif de fermeture (11) relié en mode déchirable au bord (7) de son ouverture. Ce procédé est caractérisé en ce que sur la première bande de matériau (1) de la fermeture du récipient est disposée une seconde bande (2) de matériau recouvrant partiellement la première, en ce que ces deux bandes de matériau (1, 2) sont ensuites recouvertes d'un agent d'étanchéité (5) au moins dans une zone du bord formée entre les deux bandes, et en ce que le bord (7) délimitant l'ouverture du récipient est relié sur tout son pourtour à la première et à la seconde bande de matériau (1, 2) pour constituer une fermeture déchirable. La deuxième bande (1, 2) recouvre une portion du bord de l'ouverture du récipient de telle manière que la portion montée du côté du dispositif de fermeture (11) qui est opposé à la face interne du récipient recouvre la deuxième bande (2) et, de ce fait, n'est pas prise dans l'agent d'étanchéité, formant ainsi une languette à déchirer. L'invention concerne aussi un récipient (10) doté d'un tel dispositif de fermeture (11), ainsi que l'élement couvercle (3) nécessaire à la fabrication de ce dispositif de fermeture (11).
