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.

An adjustable nozzle assembly for a liquid dispenser comprising: a nozzle cap having a discharge orifice located in a front face of a front wall thereof and a nozzle cap flange skirt extending rearwardly from said front wall, said nozzle cap flange skirt having threads for cooperating with a threaded portion of a nose bushing for selectively positioning the nozzle cap relative to the nose bushing, said flange skirt also having an inner stepped surface defined by two annular surfaces forward of said threads, the smaller diameter of the two annular surfaces being positioned to extend rearwardly from an inner wall surface of said nozzle cap and the larger diameter of the two annular surfaces being located just forward of said threads; a nose bushing comprising a body having an axially extending hollow passage extending into said body from a rear end thereof to a first inner wall and having two radial passageways extending radially outwardly to an annular slot formed in said body, said body including a threaded portion and a front face disc separated by said annular slot, and said face disc having a front face and an annular outer periphery with two angular, diametrically opposed, grooves therein; said nozzle cap being threadedly received on said nose bushing and selectively movable relative to said nose bushing to three positions including (a) an off mode position wherein said front face of said nose bushing face disc is in flush contact with said inner wall surface of said nozzle cap and with said first and smaller diameter annular surface in said nozzle cap flange skirt in flush sealing contact with said outer periphery of said face disc to prevent communication of liquid from the angular grooves to the discharge orifice, (b) a spray mode position wherein said front face of said nose bushing face disc is unseated from said inner wall surface of said nozzle cap, said unseated position defining a swirl chamber within said nozzle cap between said front face of said nose bushing face disc and said inner wall surface of said nozzle cap but with said outer annular periphery of said nose bushing face disc still in flush, sealing contact with said smaller diameter annular surface in said nozzle cap flange skirt so that liquid flowing radially outwardly from said radial passageways into said annular slot is channeled to move only through said angular grooves into said swirl chamber in a circular or spinning motion for discharge out of the nozzle cap discharge orifice in a conical spray pattern, and (c) a stream mode position wherein said outer annular periphery of said nose bushing face disc is unseated from said smaller diameter annular surface in said nozzle cap, such that said outer annular periphery of said nose bushing face disc is spaced from said larger diameter annular surface to permit liquid from said radial passageways to flow over said outer annular periphery in a non-directed manner to said discharge orifice and out of said discharge orifice in a stream pattern.
