PROBLEM TO BE SOLVED: To decrease the degree of the leak of the contents passed through a stem rubber as small as possible. SOLUTION: A leak passage of the contents is easily generated besides a jetting passage in aerosol products. The leak passage is a passage formed by a vessel main body, a gap between a vertically hanging part 4b and a standing part 5a, a gap existing inside the stem rubber 3 and a gap between an opening side inner peripheral surface 5c and the outer peripheral surface of a stem 4. Then, the upper surface part 41 of the housing 4 is formed into a wave like surface composed of an inside circular mountain part 41a, an outside circular mountain part 41b and a circular valley part 41c between the mountain parts. The stem rubber 3 is compressed toward a circular part 5b of a mountain cup by the circular mountain parts 41a and 41b. As a result, the flow resistance of the contents against the diameter direction of the stem rubber 3 is increased in the compressed parts of each circular mountain part to suppress the leak of the contents. The upper surface part 41 of the housing 4 can be a flat surface. |
