Abstract
The nozzle cap, spring valve and body assembly for a trigger sprayer comprises a nozzle cap, a spring valve and a body. The nozzle cap is capable of being screwed upon the nose bushing portion of the body. The nozzle cap has an outlet orifice located in its front face and a sleeve extending rearwardly from a front wall thereof. The sleeve is threaded inside the rear portion thereof and has an internally contoured surface on a short annular formation that is located forwardly of the threads on the back side of the front wall to provide an inner annular surface and an outer annular surface rearward of an inner wall surface of the nozzle cap and forward of the internal threads inside the sleeve. The nose bushing portion of the body has a cavity in which is received the spring valve. The nozzle cap is screwed upon (threaded on) an externally threaded portion of the nose bushing portion of the body and over the spring valve and is selectively threadably positionable between three selective positions such that the positioning of the inner wall surface of the nozzle cap and the inner and outer annular surfaces of the short annular formation in the nozzle cap selectively cooperate with an outer annular periphery of a face disc of the spring valve having two angular spin-causing grooves in the annular periphery thereof and with the second inner annular surface of the nose bushing portion of the body thereby selectively to provide an OFF mode position for containment of liquid, a spray mode position to discharge liquid in a spray pattern from the outlet orifice, and a stream mode position to discharge liquid in a stream pattern from the outlet orifice.
