ABSTRACT:
A fluid dispenser has a discharge path outletting at a discharge orifice provided in a nozzle cap in engagement with a nipple surrounding a dispenser needle valve, the cap being adjustable axially of the needle valve so as to move an open ended swirl chamber, which surrounds the discharge orifice, relative to the needle valve into and out of engagement therewith. The fluid is emitted from the discharge orifice in a concentrated and linear pattern upon disengagement between the swirl chamber and the needle valve. Otherwise, upon movement of the cap until the needle valve plugs the open end of the swirl chamber, a shaped spray pattern is created through the discharge orifice. The orifice is defined by a circular wall and by a pair of opposed projections thereon, the projections extending inwardly of the orifice and having spaced apart ends so as to effect a substantially flat spray pattern through the orifice when movement of the cap toward the needle valve causes the valve to plug the swirl chamber end.
