ABSTRACT:
The device, placed inside of the cartridge, container, tube, etc., makes it possible to maintain two different substances in chambers (6, 7) separate until the moment of use and then makes possible their mixing, and distribution of the mixture from a closeable (3) output opening (2) of cartridge, tube or container (1). The device comprises a membrane (4) easy to perforate or break (10) fastened to a fluidtight peripheral ring (4'). A perforated (13) disk (14) is provided with points (8) or the like for perforating or breaking (10) of membrane (4) at the moment of use. The disk is driven like a piston, by sliding (arrow 12) and/or rotation (arrow 17) of a rod (5) coming in a tight manner from container (1) to allow, by alternating movements, the intimate mixing of the two substances. It is provided, at the site of membrane (4), to introduce into the cartridge, container, tube or the like, a fragile container (spherical, cylindrical or in any other shape) holding one of the two substances, and adapted to be broken at the moment of use.
