Apparatus for foaming liquid cosmetic substances

Claim 1

A portable hand-held electrical apparatus for foaming liquid cosmetic substances having a self-contained electrical supply, comprising: a pistol-like housing including a housing part and a handle part, said housing part having an interior space, a bulkhead in said interior space separating said housing part into a pumping chamber and a flow communication chamber, said flow communication chamber having an inlet means and an outlet means; a vessel connected to said inlet means for flow communication between said vessel and said flow communication chamber for supplying a supply of a cosmetic substance adapted to be foamed and removably connectable with said housing part; an air supply duct having one end entering said vessel and another end connected to said bulkhead with the portion therebetween in said flow communication chamber; air pump supply means including an electrically driven pump in said pumping chamber having an inlet communicating with the exterior of said housing part to obtain ambient air and an outlet operatively connected to said other end of said duct for passing an air stream into said duct through said flow communication chamber; electrical supply containing means in said handle part including means connected to said electrically driven pump for energization thereof to drive said electrically driven pump; said means to drive said pump comprising: an electric motor for driving said pump, and a battery insertable into said electrical supply containing means for providing said self-contained electrical supply; foam generator means in the form of a porous open-cell member immersed in the substance and being disposed at said one end of said air supply duct and receiving said air stream supplied thereto by said pump through said duct and introducing said air stream into the substance in the form of a plurality of small bubbles to produce foam; and a resilient delivery nozzle means connected to the outlet means of said flow communication chamber of said housing part and communicating with said vessel through said flow communication chamber for dispensing the foam developed in said vessel, said resilient delivery nozzle means being bendable in all directions for altering thereof in relation to the position of the hand-held apparatus.
