Abstract

Ce sac en plastique, que l'on peut sceller à nouveau, est doté au voisinage de son ouverture de moyens d'écartement (21, 23) parallèles, conçus solidaires avec lui et saillant de la bande (13) formant le sac, ainsi que d'un ruban (31) d'adhésif placé entre les moyens d'écartement. On scelle le sac en déformant la bande opposée (14) du sac au-delà des moyens d'espacement, afin de faire entrer cette bande en contact avec le ruban d'adhésif. Les moyens d'écartement peuvent être articulés afin de limiter leur déformation et d'aider au contact entre les bandes. On traite la surface (19) de la bande sur laquelle l'adhésif est appliquée, afin d'améliorer l'adhésion de celui-ci, ce qui permet de détacher la bande opposée à la bande formant le sac lorsqu'on ouvre à nouveau le sac, sans arracher l'adhésif de la surface comprise entre les moyens d'écartement.
