Abstract: A package (11) has at least one bag (12, 13) and a head part (16) having a bottom part (17, 37) including a recess (19; 39), an outlet opening (20, 40) and an elevation (22, 42) which at least partially encloses a rim area of the recess (19; 39) and which projects over the bottom part (17, 37) axially toward the bag (12, 13), and a piercing device (21, 41) for the bag (12, 13).

Abstract: Cartridge for a multicomponent mass, has a housing (12) formed as a hollow profile and in which a multi-chamber pouch (13) having a plurality of chambers (14, 15) separated from each other in a longitudinal direction, is arranged and a large-surface connection region for releasably connecting the multi-chamber pouch (13) and the housing (12) and extending along a longitudinal extend of the multi-chamber pouch (13) and at least along a portion of the circumference of the multi-chamber pouch (13).

Abstract: A head part (11) for a multi-chamber tube bag (1) with a multi-component mass which can be pressed out, having a main chamber (2) for a first component and two secondary chambers (3, 4) for two other components, has a disk-shaped contact surface (12) for the multi-chamber tube bag (1) surrounding a press-out opening (13). At the contact surface (12), a plurality of raised portions (14) project toward the multi-chamber tube bag (1) and are provided at the head part (11) for narrowing the outlet regions (5, 6) of the two secondary chambers (3, 4) of the multi-chamber tube bag (1) when the multi-chamber tube bag (1) bears against the contact surface (12).
