<P>PROBLEM TO BE SOLVED: To provide a spout instrument which can perform a natural spouting operation without leaking a remaining article in a nozzle even under the condition that an overcap is removed, and can reduce a burden on a cavity part when the nozzle is inserted into the cavity part such as a nasal cavity and a liquid content is injected. <P>SOLUTION: When the nozzle 140 and a container main body do not approach and are not separated from each other, a relation between a nozzle inner cylinder part 141 and a nozzle outer cylinder part 143 is left as it is under the condition that a shoulder part 141s and a contacting face 143f are separated by an energizing force of an elastic member 142, and as the enlarged part 144e of a nozzle shaft is brought into contact with a seat face 143s of the nozzle outer cylinder part 143 to seal the inside of the nozzle outer cylinder part 143, there exists no possibility of leaking the remaining article in the nozzle 140 even under the condition that the over-cap 150 is removed. As opposed to this, when a bubble pump 120 is operated to perform approaching and leaves the container main body, the shoulder part 141s and the contacting face 143f approach each other, and the back surface 144f leaves the seat face 143s to form an annular spout, the natural spouting operation becomes possible. <P>COPYRIGHT: (C)2008,JPO&INPIT |
