Fluid dispenser method and apparatus

A nozzle for fitment to hand actuated liquid pumps having a barrel portion with a bore therethrough for passage of liquid, said nozzle comprising:

• a. an integrally formed nozzle cap which includes
• i. an end wall having a planar inside wall and an aperture through said planar wall through which liquid from said bore is dispensed, and
• ii. a skirt portion having mounting means for mounting said nozzle cap around the end portion of said barrel;
• b. an integrally formed sealing means attached to said barrel and enclosed by said nozzle cap, said sealing means having
• i. a peripheral seal portion to provide a liquid-tight seal around said barrel between said nozzle cap and said barrel, and
• ii. a check valve portion movably positioned at the mouth of said bore, said check valve portion including a seal member which selectively forms a liquid-tight bore seal with said mouth of said bore to close off the flow of liquid therethrough, and a spring member in operative relationship with said seal member whereby said spring member biases said seal member to form its said liquid-tight bore seal, but said spring member having a biasing strength sufficiently low to allow liquid pressure in said bore, developed by actuation of said pump, to move said seal member away from said bore so that said liquid-tight bore seal is opened and liquid in said bore can pass to said aperture in said nozzle cap;
• and
• c. spray means fittable within said nozzle cap and in abutment with said planar wall, said spray means and said planar wall together providing a path for the liquid as it is dispensed, said path causing said liquid to break up and form a spray pattern.
