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.
