ABSTRACT:
A two-piece nozzle, for fitment to hand actuated liquid pumps having a barrel portion and a bore therethrough for passage of liquid, is disclosed. The nozzle has an integrally formed nozzle cap which is mounted to the end portion of the barrel. Enclosed within the nozzle cap is an integrally formed sealing structure which is attached to the barrel of the pump. The sealing device provides a peripheral liquid-tight seal around the barrel between the nozzle cap and the barrel. It also provides a check valve which is movably positioned at the mouth of the bore to provide a liquid-tight bore seal. The check valve is biased to provide the liquid-tight bore seal which bias can be overcome by liquid pressure in the bore developed upon actuation of the pump.
