Counter-mounted viscous liquid dispenser having improved reservoir assembly
First Claim
1. A reservoir assembly for use with a counter-mounted dispenser having an actuator element operatively movable to cause a viscous liquid to be dispensed, said assembly comprising:
- a container housing for containing therein a quantity of the viscous liquid, said container housing having a top portion defining at least one actuator opening for receipt of the actuator element;
a pump device located within said container housing and operative to pump the viscous liquid through a fluid outlet;
said pump device having a tubular piston axially movable within a pump cylinder such that reciprocatively movement of said tubular piston causes the viscous liquid to be drawn through said tubular piston and moved toward said fluid outlet; and
an engaging element fixedly connected to said tubular piston for movement therewith, said engaging element having a contact portion registered with said actuator opening so as to be engaged by the actuator element.

Abstract
A counted-mounted apparatus for dispensing viscous liquid, such as hand soap, includes an improved reservoir assembly. The reservoir assembly includes a container housing in which a predetermined quantity of the viscous liquid is contained. Bayonet tabs or other suitable means may be provided on the housing to effect direct attachment to a canister top of the dispenser. At least one actuator opening is defined in a top portion of the container housing for receipt of the dispenser'"'"'s actuator rod. A free distal end of the rod pushes against an engaging element located within the housing. When the engaging element is reciprocatively moved by the actuator rod, a pump device located in the housing functions to push the viscous liquid into a flexible delivery tube. The pump device is preferably a common lotion pump which has been suitably modified.
