<p>In the process for assembling a cartridge with at least one container (2, 3) and each container having a piston, after having introduced the piston (9, 10) into the container (2, 3), at least one retaining means (14, 17) with a retaining edge (A - F) is formed into the inner surface (15) of the end portion of the wall (16) of the container, in a position between the rim of the container wall (16) and the rear surface of the piston. Such retaining means improve security of the cartridge and prevents the piston to be expulsed, even under the added difficulties of air transport. <IMAGE></p> |
