ABSTRACT:
The invention relates generally to a foam dispenser having a reservoir, a housing, and a chamber. The reservoir delivers fluid to the housing and the chamber through a dip-tube. The chamber moves within the housing in response to fluid pressure or air pressure from the reservoir, allowing air and foamable liquid to enter the chamber. Foam-producing packing material inside the chamber causes the air and foamable liquid to mix and produce foam.
