ABSTRACT:
A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually vertically reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The liquid dispenser is constructed with three biased closed valves that prevent leakage from a liquid container attached to the dispenser should the dispenser and container be positioned on their sides or be inverted.
