ABSTRACT:
A nozzle for fitment to hand actuated liquid pumps having a barrel portion with a bore therethrough for passage of a liquid is disclosed. The nozzle features an integrally formed nozzle cap which is mounted to the barrel and which encloses an integrally formed sealing structure. The sealing structure provides a peripheral seal to provide a liquid-tight seal around the barrel between the nozzle cap and the barrel. The sealing structure also provides a check valve portion which is movably positioned at the mouth of the bore. The check valve is biased to form a liquid-tight bore seal. This bore seal is overcome by liquid pressure which builds in the bore upon actuation of the pump. Also provided is a spray member which is fittable within the nozzle cap and which is in abutment with the end wall of the nozzle cap. The spray member, along with the wall of the nozzle cap which it abuts, form a path for the liquid as it is dispensed, which path will cause the liquid to break up and form a spray pattern.
