Abstract

A trigger actuated sprayer for dispensing liquid products featuring a movable hinge point for the trigger handle in the form of a flexure. The flexure allows a constant orientation for the spray nozzle to be maintained by accommodating changes in radial distance as the trigger handle is depressed, while decreasing the complexity and parts count of the overall structure. A sealing member is incorporated into the piston and the cylinder of the pump for the device to reduce leakage of the liquid product when the pump is not used or is inverted.
