Abstract
A device for use with foamable liquids includes a reservoir adapted to contain a quantity of a foamable liquid and an air pump for supplying air to be mixed with the foamable liquid to form a foam. The foamable liquid reservoir is isolated from the air supplying pump. A mixing chamber is provided in which the foamable liquid and air from the air supplying pump can interact to create the foam. A first passage leads from the reservoir of foamable liquid to the mixing chamber and a pump is provided for pumping the foamable liquid from the reservoir through the passage to the mixing chamber. A second passage is provided from the air supplying pump to the mixing chamber to introduce air into the mixing chamber.
