Abstract

A cartridge has a reception chamber extending in a longitudinal direction for a medium to be dispensed. The cartridge has a head part and a cartridge wall which bound the reception chamber, the head part having an outlet for the medium. The cartridge wall is at least regionally a film and the head part is a stable-shape part. The head part is sealingly and in particular unreleasably connected to the cartridge wall and the cartridge is a collapsible cartridge. The cartridge can be converted from an expanded state in which the reception chamber has a maximum volume into a collapsed state in which the reception chamber has a minimal volume. The cartridge not yet filled with medium is in a collapsed state. Furthermore, a method of manufacturing such a cartridge is described.
