ABSTRACT:
A unitary liquid dispensing cap with integral actuator and valve assemblies is provided which includes a centrally located bellows to provide a restoring force to drive the valve back to the closed position after dispensing the liquid. A guide is provided for the valve and includes projections which cooperate with mating projections on the valve assembly to control movement of the valve. The valve assembly may be cocked to provide positive sealing of the dispensing passage by the valve.
