<p>A child-resistant trigger actuator pump sprayer includes a detent (26) on a forward wall of the trigger lever (28) for engagement with either an outer flat wall of the nozzle cap (18) or a notch in the rearward edge of the cap for locking the cap in its discharge closed position. Rotation of the cap (18) to one of its on positions is facilitated by unlocking the cap as the operator applies a slight pull force to the trigger lever to disengage the detent (26) from the notch (31) or from the external flat wall of the cap. <IMAGE></p> |
