The adjustable nozzle assembly for a trigger sprayer comprises a nose bushing and an integral nozzle cap capable of being screwed upon the bushing. The nozzle cap has a discharge orifice located in its front face and a flange skirt extending from a front wall thereof. A nozzle cap flange skirt is threaded inside the rear portion thereof and an internally contoured or stepped surface is located forwardly of the threads to provide reduced diameter annular surfaces at two locations rearward of an inner wall surface of the cap and forward of the internal threads inside the nozzle cap flange skirt. The nozzle cap is screwed upon (threaded on) an externally threaded portion of the nose bushing and is selectively threadably positionable between three selective positions such that the positioning of the inner wall surface and the annular surfaces of the nozzle cap flange skirt selectively cooperate with a front face and annular periphery of a nose bushing face disc having two angular grooves in the annular periphery thereof thereby selectively to provide a stop mode position for containment of liquid, a spray mode position to discharge liquid in a spray pattern from the discharge orifice, and a stream mode position to discharge liquid in a stream pattern from the discharge orifice. |
