For a simple and dependable gas evacuation and to prevent any undesirable leakage of the filler material, the gas evacuation element is at least one cover disk that forms a labyrinth path running transverse to the plunger axis. The path is located between the contact surface of the cover disk facing the gas evacuation opening and a corresponding contact surface on the cartridge plunger.
