ABSTRACT:
A syringe for dispensing a liquid as an atomized spray has a cylindrical barrel, a plunger movable axially in the barrel, a tubular nozzle at one end of the barrel, and a short fixed stem in the nozzle. A cup shaped nozzle tip has internal first spaced lands to frictionally engage the stem and define axially extending passages therebetween. A centrally apertured end wall of the nozzle tip has circumferentially spaced second lands to serve as abutments for the end of the stem. Troughs in the end wall between the second lands define further passages with the end of the stem for turbulently passing the liquid out of the aperture as an atomized spray.
