<p>RIGGER ACTUATED DISPENSING PUMP A reversible trigger actuated dispensing pump employs a reciprocal plunger having a passage for communication with a pump at one end and a nozzle at the other end. The trigger includes a body portion with structure to cooperate with the plunger to permit the trigger to be releasably and pivotally mounted on the plunger in at least two angularly spaced positions. An actuating gripping portion extends from the body portion and from the pump when the trigger is mounted thereon. In this manner, when the trigger is mounted on the plunger and the actuating gripping portion is pivoted, the body portion will pivot and reciprocate the plunger and operate the dispensing pump.</p> |
