ABSTRACT:
A fluid pump dispenser 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. Fluid is discharged through the nozzle structure by actuating a trigger to reduce the volume of a pump chamber in communication with the outlet check valve. The volume of the pump chamber may be reduced by operating a piston within the chamber or by flexing a wall of a tubular member having an open end in communication with the outlet valve.
