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.

Device for mixing, foaming and dispensing liquids from separate compressed-gas containers

In a two-component container (,) a connection is formed between two chambers (,) by ejecting a sealing plug (,). By screwing one container (,) into a thread (,) connected to another container (,) the sealing plug (,) which is provided with two stoppers (,) is pressed out of its retaining members (,). Sealing takes place in a reliable manner by two separate stoppers (,) of the sealing plug (,). When the container (,) is screwed in, first the lower stopper (,) is ejected by the upper stopper (,) and then the upper stopper (,) is ejected by an ejection member (,). The two-component container (,) is suitable for holding peroxide and hair dye separately. After it has been ejected, the sealing plug (,) assists in the mixing of the said two components.
