Abstract (en)
[origin: US4690306A] A dispensing device comprises a cartridge unit with at least two chambers containing liquid or pasty substances and pistons therein being connected with each other by at least one blade adapted for cutting through a dividing wall, between two chambers and separating their contents, only one piston assembly being required which can be operated with a propellant under excess pressure preferably not exceeding 6 bars. As no piston rod is required the construction of the device is very compact. In a first step for actuating the pistons, the cartridge unit is moved forward toward an exit end of the device bearing a discharge nozzle whereby valves in the device are opened and contents from the cartridge unit are conveyed to the discharge nozzle. After each discharge a restoring element returns the cartridge unit to a rearward end position whereby the valves are closed and no contents can leak from the cartridge.
