Abstract:
1. A cartridge for a multi-component mass, comprising a housing ( 12 ) formed as a hollow profile; a multi-chamber pouch ( 13 ) arranged in the housing ( 12 ) and having a plurality of chambers ( 14 , 15 ) separated from each other in a longitudinal direction; and a connection region formed by an adhesive provided between an inner profile of the housing and an outer profile of the multi-chamber pouch releasably connecting the multi-chamber pouch ( 13 ) and the housing ( 12 ) and extending along a longitudinal extent of the multi-chamber pouch ( 13 ) between only a portion of a circumference of the outer profile ( 28 ) of the multi-chamber pouch ( 13 ) and a respective portion of a circumference of the inner profile of the housing ( 12 ), a piston located in the housing for applying pressure to the pouch, the adhesive connection region is so formed that upon application of pressure on the pouch by the piston during a discharge process the outer profile of the multi-chamber pouch is separated from the inner profile of the housing, without generating high counter-forces at the adhesive connection region, such that the adhesive connection region between the multi-chamber pouch and the housing is not so strong as to regionally tear the pouch during the discharge process.
