Abstract
A valve actuator that establishes a secondary valve which may be positioned to prevent unintentional dispensation of fluid product. The actuator includes a dispensing head, for example, mounted on a hollow plunger, rotatably positionable relative thereto and valvingly cooperative therewith to selectively open (facilitate) or close (block) discharge passage of fluid product. The dispensing head preferably includes a depressible latching pawl that is reciprocatively biased to retainingly engage the plunger when the dispensing head is rotated to the close valving position and hold the dispensing head from further positional rotation until the pawl is depressingly disengaged.
