ABSTRACT:
The dispensing pump has an actuator button which is depressible immediately alongside of the stationary discharge spout of the pump so that, when the button is fully extended in its standby position, its upper surface is approximately flush with the upper end extremity of the spout. A locking cover on the button may be slid into a closed position at this time covering the open end of the spout to both seal the latter and securely lock the button against accidental depression. An alternative embodiment provides a discharge passage within the button itself which may be opened and closed by appropriate positioning of a slide cover carried by the button.
