Abstract
A fluid pump dispenser includes a dispenser trigger which may be located in pivotable engagement with the dispenser housing and pump piston after shipment. The initial actuation of the trigger moves the pump piston and a container conduit, engaged thereto, to open a container vent shipping seal provided by mating surfaces on the conduit and the container cap. Fluid carried from the container by the conduit enters the pump chamber through a central orifice in the piston. A flexible member located on the piston functions as an inlet check valve for the conduit and as a piston ring. The fluid dispenser also includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap.
