Abstract

L'invention concerne un dispositif de postage (210) comprenant un corps (215) et une ouverture de type fenêtre (216). L'ouverture est recouverte d'un film de matériau transparent collé au corps. Au moins une ligne de faiblesse (128) est formée dans le corps et entoure au moins partiellement le film, ceci permettant de séparer le film du corps en vue du recyclage. La ligne de faiblesse (128) peut être conçue de manière à définir une bande (236) s'étendant en travers d'une face avant du dispositif. La bande (236) peut être séparée en déchirant le long de la ligne de faiblesse de façon à former une ouverture permettant d'accéder à l'intérieur du dispositif et de retirer facilement le film. En variante, la ligne de faiblesse (128, Fig. 3) peut entourer totalement le film et définir une partie languette (124, Fig. 3). Dans d'autres modes de réalisation, le film (18, Fig. 1) présente une partie languette (24, Fig. I) que l'on tire pour séparer le film du corps. Le film peut être collé à l'aide d'un adhésif décollable et peut être collé sur une surface extérieure du corps.
