Abstract
Pump dispensers dispense liquids from the interior of a container without the need for removing the top. The pump dispenser employs a manually operated disk to which a diaphragm is attached to force air from an air chamber into the container interior where it displaces the liquid contents forcing them up a fluid tube and out a spout. A valve seals the air chamber except during pumping to prevent the entry of liquids into the air chamber.
