Abstract

A compressed gas container apparatus having at least two compressed gas containers disposed side by side, each for one foamable liquid product which contains a liquidified propellant gas, wherein both compressed gas containers are each provided with a valve; both valves are actuatable in common by a top fitting, and each valve is provided through the top fitting with a connecting conduit; the connecting conduits discharge into a mixing chamber and an expansion conduit adjoins the mixing chamber and on its end has a foam dispensing opening; wherein the connecting conduits and the mixing chamber have such small cross-sectional areas that when a product is dispensed, the products flowing through the connecting conduits and the mixing chamber remain in a liquid phase.
