ABSTRACT:
A cone spray nozzle is provided in a tubular member for carrying a fluid to be sprayed. The tubular member has at least one opening with a plurality of grooves, preferably symmetrical, around the periphery thereof. In each opening is positioned a dispersion member having a stem portion for fastening to the tubular member and a tapered head portion with an angular, typically conical surface for dispersing the fluid. The fluid is ejected from the tubular member through the grooves to strike the tapered head portion, which in turn disperses the fluid in a generally conical spray pattern. Preferably the nozzle is made by punching the opening having the peripheral grooves with a die and inserting the dispersion member which is preferably a standard flat-head screw or rivet.
