Abstract
Disclosed is a substantially modularized countertop mounted liquid soap dispensing system. The system includes a delivery module comprised of a housing, a frame and an actuator channel through said frame. Residing in the actuator channel is an actuator rod assembly. The lower portion of the actuator rod assembly is free. Attached to the lower portion of the frame is a canister top adapted to engage a canister for enclosing a disposable liquid soap reservoir module.
The liquid soap reservoir module is substantially completely enclosed such that the liquid soap within is not exposed to the atmosphere until it is pumped from the module. The disposable reservoir module includes an enclosing top section, a lower cap means and a pump affixed to the lower cap means. There is a guide cylinder extending from the enclosing top section to the pump for receipt of the free end of the piston rod assembly. The pump is a positive displacement pump which includes hinged winged members which extend outwardly in sealing engagement with the internal walls of the pump housing on the downward pumping stroke. As the pump piston moves upwardly in the pump housing in a non-pumping stroke, the weight and viscosity of the liquid soap within pump housing above the hinged sections causes the hinged sections to pivot inwardly away from the internal walls of the pump housing thereby allowing liquid soap to pass around and below the pump piston in preparation for the next downward pumping stroke. A
check valve is provided in the pump discharge to prevent soap from backflowing on the non-pumping stroke. In such manner, the pump piston functions simultaneously as a pump piston and a check valve.
A delivery tube extends from the pump through the spout of the dispensing system thereby preventing liquid soap from contacting the internal walls of the spout.
