Abstract (en)

[origin: EP2145652A1] The cartridge (1) has a housing (10) for housing an additive i.e. film-forming additive. An outlet passage (11) is arranged in the housing. An obturator unit i.e. pressing piston (30), obturates the outlet passage in the housing. A maintaining unit i.e. tapered head (32), maintains the obturator unit in an obturation position of the outlet passage, while external pressure is lower than a predetermined threshold value. The obturator unit is associated with a toric sealing joint (40). An independent claim is also included for a liquid extinguisher cylinder comprising a cartridge.
