ABSTRACT:
A manually operated, vertically reciprocating liquid pump dispenser is removably connectable to a bottle containing liquid and simultaneously pumps liquid from the bottle and air from the exterior environment of the dispenser and mixes the liquid with the air to produce a foam that is dispensed from the dispenser. The dispenser includes a closure connector that provides a mechanism for venting the interior of the bottle to the exterior environment of the dispenser while avoiding leakage of the liquid from the bottle, and also incorporates a mechanism for locking the dispenser to prevent unintended pumping of liquid from the bottle.
