摘要

PROBLEM TO BE SOLVED: To provide a nozzle mechanism switchable between mist spray and straight spray for a trigger type sprayer, which enables a good straight spraying state.;SOLUTION: A boss shaft is supported on the front part of a spin element having both front and rear ends opened, the first fitting cylindrical part of a cap is rotatably fitted to the outer surface of the boss shaft, the boss shaft has a first groove part 14 for straight injection and a second groove part for mist injection, a shared groove part 30 is provided in the rear inner surface of the first fitting cylindrical part to extend in a back-and-forth direction, the cap has a spin groove 26, switching of each groove is enabled by rotation of the cap with respect to the spin element, the cap has the shared groove 30 formed wider than the thin groove part 26b of the spin groove 26, and in a straight spray mode, the first groove part 14 is prevented from overlapping the thin groove part 26b.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2016,JPO&INPIT
