<P>PROBLEM TO BE SOLVED: To reduce a change in a discharge state generated accompanied by the alteration of a content discharge range. <P>SOLUTION: A push button 21, to which an exclusive upper inflow port 21a and an exclusive under inflow port 21b both of which communicate with an upper discharge hole 11a and a lower discharge hole 11b are formed, is attached to a changeover member 31 having a slit 31 for opening and closing the lower inflow port formed thereto in a revolvable manner. The upper inflow port 21a always communicates with an inner space 31i through a space region 31j. In a one-way mode, the under inflow port 21b is closed by a cylindrical part 31b and content is discharged to a narrow range only from the upper discharge hole 11a. When the push button 21 is revolved, a two-way mode can be set and the under inflow port 21b communicates with the inner space 31i (upstream passage) through the slit 31c of the changeover member 31 and the content is discharged to a wide range from both discharge ports 11a and 11b. Since the downstream passages to the respective discharge ports are independent, even if a discharge mode is changed, the change in the state of the discharged content is small. <P>COPYRIGHT: (C)2004,JPO |
