Title
(EN) BARRIER CARTRIDGE HAVING A PISTON
(FR) CARTOUCHE BARRIÈRE AYANT UN PISTON
Abstract
(EN)
The head side of a cartridge has a side wall (12) and an end wall (13). The walls (12, 13) are provided with a first barrier layer (3) or a second barrier layer (4). The second barrier layer (4) is arranged on the inner side of the end wall (13), not on the inner side of the side wall (12). For this purpose, the side wall (12) with the first barrier layer (3) can extend beyond the top side of the end wall (13). Thereby, an additional protection against diffusion from the side of the side wall (12) in the transition area between side wall (12) and end wall (13).
(FR)
L’invention concerne le côté tête d'une cartouche comportant une paroi latérale (12) et une paroi terminale (13). Les parois (12, 13) sont dotées d'une première couche barrière (3) ou d'une seconde couche barrière (4). La seconde couche barrière (4) est disposée sur le côté interne de la paroi terminale (13), et non sur le côté interne de la paroi latérale (12). À cet effet, la paroi latérale (12) présentant la première couche barrière (3) peut s'étendre au-delà du côté supérieur de la paroi terminale (13). Ainsi, une protection supplémentaire est obtenue contre la diffusion depuis le côté de la paroi latérale (12) dans la zone de transition entre la paroi latérale (12) et la paroi terminale (13).
