Abstract

A cartridge for a medium to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall. The film bounds a cartridge chamber for the medium to be dispensed and extends at least partially in a longitudinal direction of the cartridge. The head part includes a collar surrounding the dispensing outlet in a radially outer region of the head part, wherein the collar extends in the longitudinal direction and has an inner circumferential surface. A front end of the film is sealingly and non-releasably connected to the inner circumferential surface of the collar. The film is attached to the inner circumferential surface of the head part at a contact surface that is different from the outer surface of the film.
