To allow cost-effective production of the device, which operates with the aid of a piston-cylinder system, and to allow it to be designed as a dispenser or pack in an optimum way with respect to how it can be filled, leak-tightness, how it can be discharged and mixing, flexible bellows-type product containers (14, 15), which are openable only towards the outlet orifices (18, 19) of the dispenser (1), are fitted in the cylinders (4, 5). <IMAGE> |
