Abstract

L'invention concerne un emballage à ouverture par pliage (1) qui permet d'éviter qu'une partie d'ouverture par rupture soit ouverte par une force externe agissant sur cette dernière pendant le transport, le stockage et similaire, et qui peut être produit en masse. L'emballage à ouverture par pliage (1) est pourvu d'un matériau de face (2) qui s'ouvre par rupture lorsqu'il est plié. Le matériau de face (2) est pourvu : d'un matériau de feuille (5) présentant une partie de pliage pouvant être pliée (9) et une partie d'ouverture par rupture (10) destinée à former une ouverture lorsqu'elle est pliée au niveau de la partie de pliage (9) ; d'un matériau d'étanchéité (6) destiné à étanchéifier la partie d'ouverture par rupture (10) en étant collé à la partie d'ouverture par rupture (10) et aux parties voisines de cette dernière sur le matériau de feuille (5) ; et d'un matériau de recouvrement (7) destiné à recouvrir le matériau d'étanchéité (6). Le matériau de recouvrement (7) est collé de manière à recouvrir la partie de pliage (9), à l'exception de l'endroit où une partie de recouvrement (11) du matériau d'étanchéité (6) recouvre la partie d'ouverture par rupture (10). Une partie de prévention de collage (12) destinée à réduire la zone de collage ou à empêcher la partie de recouvrement (11) d'être collée au matériau de recouvrement (7) et/ou au matériau de feuille (5) est formée au-dessus et/ou au-dessous de la partie de recouvrement (11) du matériau d'étanchéité (6).
