PURPOSE: To obtain a high degree of atomization and to form a round spray pattern by constituting from a nozzle which can rotate around a rotary shaft at an angle within a specified range and a trigger which is interconnected to the nozzle so that the nozzle rotates, upon pulling of the trigger, simultaneously with the discharge of fluid.

CONSTITUTION: In a hand pump spray 100 for fluid pressurized and sent from a liquid tank to the outlet of a passage, a rotatable nozzle 102 is fitted around the passage of the spray 100. The nozzle 102 is interconnected to the trigger 112 of the spray 100 so that the nozzle rotates, upon pulling of the trigger 112, simultaneously with the discharge of the fluid to the atmosphere, and the nozzle 102 rotates around an axis of rotation through the center of the discharge end of the nozzle 102 covering an angle of rotation from about 90° to about 360°. As a result, the dispensed fluid has a high degree of atomization and a desirable round spray pattern.
