Abstract:
A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.

Claim (Index 1):
A trigger-type ejector comprising:\n an ejector body attached to a mouth of a container in which a liquid is contained and including a flow path of a liquid; a pump actuated by operation of a trigger and pumping the liquid in the container to the flow path; and a nozzle head attached to the ejector body by being continuous with an outlet of the flow path and ejecting a liquid pumped to the flow path from an ejection hole to an outside, the trigger-type ejector including: a pressure storage chamber defined and formed in the nozzle head and communicating with the flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion and a small-diameter pressure receiving portion facing an opposite side to the large-diameter pressure receiving portion, the pressure storage plunger being disposed in the pressure storage chamber and being movable between a close position where the ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, wherein, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member such that the liquid in the pressure storage chamber is ejected from the ejection hole to an outside.
