Abstract
The one-piece foamer nozzle comprises an inner cap portion, an outer barrel portion, and an internal wall inside the nozzle between the cap portion and the barrel portion. The internal wall has a central orifice therethrough. The cap portion has a cavity and structure in the cavity for receiving and mating with a nose bushing mounted to the front end of a trigger sprayer. The structure has passageways adapted to register with passageways on the nose bushing when the nozzle is rotated to a predetermined position on the nose bushing to direct liquid in a swirl whereby a conical spray exits the central orifice when the trigger sprayer is operated. The outer barrel portion has an inner, generally cylindrical, wall surface. The nozzle further has a short annular formation coaxial with the orifice and fixed to and extending outwardly from the internal wall around the orifice. The short annular formation has an axial extent from the internal wall sufficient to cause a generally cylindrical inner surface of the annular formation to interfere with at least a portion of the conical spray exiting from the orifice upon operation of the trigger sprayer, whereby some of the conically sprayed liquid engaging the inner surface of the short annular formation will be deflected into the path of the conical spray of liquid flowing toward the inner, generally cylindrical, wall surface of the outer barrel portion, thereby to enhance turbulence and mixing of air and liquid in the outer barrel portion to enhance the generation of foam.
