ABSTRACT:
A foamer, and related method, wherein the foamer comprises a container in which a large supply of foamable liquid is disposed. A predetermined amount of foamable liquid is displaced from time to time from the large container to a relatively small capacity pump chamber, under force of manually-created negative pressure. Manually-created positive air pressure displaces a fixed quantity of foamable liquid from the pump chamber as a stream to a foam-creating mixing chamber where a controlled amount of the air under positive pressure is introduced into the stream of foamable liquid to produce effluent foam.
