Claim:
A multicomponent cartridge ( 1 ) for separate storage and coextrusion of at least two components of a flowable composition, having a plastic cylinder ( 2 ) for receiving the composition, having an extrusion piston ( 4 ) for extruding the composition, and having at least one outlet opening ( 5 ) for the composition, the components of the composition being stored separately from one another in at least two chambers ( 8 , 9 ) of the cylinder ( 2 ) that extend in the longitudinal direction of the cylinder ( 2 ) of the multicomponent cartridge ( 1 ), characterized in that the cylinder ( 2 ) has a diffusion-proof film ( 7 ), which is composed a material different from the components and different from a material of the cylindrical ( 2 ) and extends over the length of the cylinder ( 2 ), and an inner region ( 12 ) of the film ( 7 ) forms a partition ( 13 ), which divides the cylinder ( 2 ) into the chambers ( 8 , 9 ) extending in the longitudinal direction, and an outer region ( 11 ) of the film comprising a loop that is embedded around it with the plastic of the cylinder ( 2 ) and is joined in material-locking fashion to the cylinder ( 2 ).
