Abstract
A trigger actuated pump sprayer has a nozzle cover for sealing the discharge orifice closed against leakage by the provision of a cup-shaped element on the cover which telescopes about a nosepiece in which the orifice is formed and fluid tightly engages a seal ring extending laterally outwardly of the nosepiece in the closed position of the cover. The cover is locked in its closed position and is rendered child-resistant by the provision of at least one resilient lock pin extending through an opening in the sprayer housing requiring an inward depression of the lock pin with one hand and a flipping open of the cover with the other hand.
