A trigger-type sprayer (10) comprising: a body (11) having a first flow path (11a) through which a fluid can flow, a second flow path (11d) connected to the first flow path (11a), and a cylindrical cylinder chamber (11b) that connects to the second flow path (11d); a hollow piston (13) slidably incorporated inside the cylinder chamber (11b), having a valve seat (13b) for a second valve (14), having a hollow section (13d), and sliding forward and backwards as a result of the operation of a trigger (12); the second valve (14) incorporated inside the hollow section (13d) of the hollow piston (13) and positioned on the downstream side; and a first valve (15) incorporated inside the cylinder chamber (11b) and positioned on the upstream side. The first valve (15) opens as a result of the first valve (15) being push-pressured by the second valve (14). The air in the space between the second valve (14) and the first valve (15) can be readily released and fluid leakage during use can be prevented. |
