ABSTRACT:
A self contained viscous liquid dispenser with a foaming pump mechanism includes a housing defining an internal liquid reservoir. A foaming pump mechanism is configured with the housing and includes a horizontally disposed pump chamber fitted through an opening in the housing to extend into the reservoir. A pump cylinder is slidably disposed and retained in the chamber. Actuation of the pump cylinder results in a liquid/air mixture within the pump chamber being pressurized and dispensed from the chamber as a foam.
