Abstract
The nozzle assembly comprises two pieces, they being: a nozzle cap; and, an integral nose bushing on which the nozzle cap is threadedly received. The integral nose bushing includes a body portion received and mounted in a body of a trigger sprayer and a bushing portion integral with the bushing portion. The bushing portion includes a generally cylindrical portion having a distal end and a proximal end with the proximal end having threads thereon and the distal end having a smooth outer cylindrical surface. The cylindrical portion has an annular slot therein defining an outer cylindrical flange and a central cylindrical portion. The central cylindrical portion has an outer end which extends outwardly of the outer cylindrical flange and which has an outer end having an annular wall defining therein a swirl cavity. The nose bushing has a passage therein communicating a waterway in the bushing portion with the annular slot in the cylindrical portion. The nozzle cap includes a generally cylindrical skirt formation extending rearwardly from a front wall of the cap having an orifice extending through the front wall. The generally cylindrical skirt formation includes an internal threaded portion which is adapted to mate with threads on the threaded portion of the nose bushing. The nozzle cap also has, on a rear surface of the front wall, an axially, rearwardly extending annular projection which surrounds the orifice and which is sized to be received in and seal with the walls of the swirl cavity.
