Dispensing pump with deformable pump wall and positive shut-off










Image Number 4 for United States Patent #6755327.

A container-mounted dispensing pump incorporates an elastically deformable pump wall and elastomeric valves for controlling the flow into and from the pump chamber. A mechanism at the movable end of the deformable pump wall engages the outlet valve to effect positive closure thereof when the actuator is disposed in an extended, shipping position. With the pump actuator placed in the shipping position, the close outlet valve will preclude leakage of the container contents though the pump.
