PROBLEM TO BE SOLVED: To provide a trigger type sprayer which enables easy air bleeding in a space between a second valve and a first valve and prevents leakage of a liquid during use.SOLUTION: The invention relates to a trigger type sprayer 10 comprising: a body 11 including a first passage 11a through which a liquid may flow, a second passage 11d which communicates with the first passage 11a, and a cylinder chamber 11b which communicates with the second passage 11d and has a cylindrical shape; a hollow piston 13 which is slidably incorporated into the cylinder chamber 11b, has a valve seat 13b of the second valve 14 and a hollow part 13d, and is slid back and forth by operation of the trigger 12; the second valve 14 which is incorporated into the hollow part 13d of the hollow piston 13 and is positioned at the downstream side; and a first valve 15 which is incorporated into the cylinder chamber 11d and is positioned at the upstream side. In the trigger type sprayer 10, the second valve 14 presses the first valve 15, thereby opening the first valve 15. |
