Abstract:
A trigger sprayer (1, 100) is provided with: a pressure storage chamber (58) defined and formed within a nozzle head (50) and in communication with a flow passage (P2) through a communication hole (52f); a pressure storage plunger (53) provided with a large-diameter pressure receiving section (53c) and a small-diameter pressure receiving section (53e) which faces in the direction opposite the large-diameter pressure receiving section (53c), the pressure storage plunger (53) being disposed within the pressure storage chamber (58) and being movable between a closing position where the pressure storage plunger (53) closes a spray hole (51c) and an opening position where the pressure storage plunger (53) opens the spray hole (51c); and a pressing member (54) disposed within the pressure storage chamber (58) and pressing the pressure storage plunger (53) toward the closing position. The trigger sprayer is configured such that, when the pressure of liquid within the pressure storage chamber (58) reaches a value higher than or equal to a predetermined value, the pressure storage plunger (53) moves from the closing position to the opening position against the pressing force of the pressing member (54) and the liquid within the pressure storage chamber (58) is sprayed to the outside from the spray hole (51c).
