A process of forming a nozzle for discharging a fluid comprising locating in an upright position, a tubular conduit having internal threads formed on the inside thereof at opposite ends. A core having a conical shaped end is located within the conduit such that it extends out of the conduit, and is spaced from the inside wall of the conduit down to the threads at the lower end of the conduit. The conical shaped end of the core and the conduit are surrounded with a mold having its inside wall spaced from the conical shaped end of the core. The space between the inside wall of the conduit and the core is filled with a liquid material. The liquid material is allowed to harden to form an elastic member molded within the conduit. The mold and core are removed and a portion of the elastic member extending beyond the conduit is severed to form a discharge opening.

A process of forming a nozzle for discharging a fluid; comprising the steps of: locating in an upright position a tubular conduit having an opening formed therethrough and having internal threads formed on the inside thereof at opposite ends, said internal threads formed on the inside of said conduit at said opposite ends being threaded in opposite directions respectively, locating within said conduit a core having a conical shaped end extending upward and out of said conduit, said core being spaced inward from the inside wall of said conduit down to a lower level between the upper and lower ends of said internal threads at the lower end of said conduit, surrounding said conical shaped end of said core with a mold having its inside wall spaced from said conical shaped end, filling the space between the inside wall of said conduit and the core with a liquid material starting with said lower level and extending upward to the top of said conduit, filling the space between said conical shaped end of said core and the inside wall of said mold with said liquid material up to a level above the top of said core, said liquid material being characterized such that when it hardens it becomes elastic, allowing said liquid material to harden to form an elastic member molded within said conduit, removing said mold and said core, and severing a portion of said elastic member extending beyond said conduit to form a discharge opening for the aperture extending into said elastic member formed upon removal of said core.
