Abstract

A manually operated liquid dispensing device, of the type having a component retaining body, a submerged tube directed downward from the body, a bore defined within the body and opening outward to communicate with ambient air, a movable piston within the bore and bounding with the bore a compartment of varying dimensions, inlet and outlet passages for delivering liquid to and from the compartment of varying dimensions limited by the piston and bore, one or more check valves to regulate the flow of liquid, a mechanism for displacing the piston within the bore between a normal, non-pumping position and a pumping position, and a discharge port communicating with the outlet conduit for dispensing the liquid, characterized in that the body means of Component retention contains a ventilation passage that extends through the body and ends at one end in the bore, and because the distributor contains a sealing means for the ventilation passage that, in the normal non-pumping position, prevents communication between the ventilation passage and the ambient air and which, in the pumping position, allows free communication between the ventilation passage and the ambient air.
