<P>PROBLEM TO BE SOLVED: To enhance responsiveness when the content emitting operation is started. <P>SOLUTION: A tapered surface 14a is formed on a side surface of a stem rubber supporting annular stepped part 14 provided on a stem 11, and an annular space area 14b for passing the content which is communicated with an ejection hole part 12a even in a stationary mode is formed between the tapered surface and a cone-shaped part 13 of the stem 11. When a passage 13c is formed while a shoulder part 13b of the cone-shaped part 13 is separate from the stem rubber 31 in a service mode in which the tilting direction of the stem 11 is deviated from the position of the ejection hole part 12a, the content passes through an auxiliary route via the annular space area 14b and is directed to the ejection hole part 12a. Since the sectional area of the auxiliary route is larger by the part of the annular space area 14b, responsiveness when starting the ejection of the content is excellent. In addition, the sectional area of the ejection hole 12a is reduced toward the downstream side, the content is accelerated when fed into a longitudinal passage 11a for ejection, and responsiveness becomes more excellent when starting the ejection of the content. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
