PROBLEM TO BE SOLVED: To prevent the leakage of contents, enhance an ejection efficiency and improve operability with respect to a button for intermittent ejection in an aerosol container. SOLUTION: A first cylindrical valve 17 and a second cylindrical valve 22 penetrating therethrough are provided inside a cylinder 16. An outer circumference of the first valve 17 is airtightly contacted with an inner circumferential face of the cylinder 16. The second valve 22 is formed with an inside portion 23 and an outside portion 24. The inside portion 23 has a valve part 23a provided on the rear end side thereof to open and close the gap between the first valve 17 and the second valve 22 and has a stem part 23b provided on the forward end side thereof. A plurality of grooves extending in the lengthwise direction of the stem part 23b are provided in the outer circumferential surface thereof. On the other hand, the outside portion 24 formed into a cylindrical shape has an ejection port 24a provided at a top end thereof and also a center hole 24b leading to the ejection port 24a. The stem part 23b is inserted into the center hole 24b, and a plurality of outlet passages 23c leading to the ejection port 24a through the grooves are formed between the inside portion 23 and the outside portion 24. |
