<P>PROBLEM TO BE SOLVED: To provide a capped container capable of removing a large amount of gas generated under a stable state even when stored liquid including non-soluble powder is stored in it. <P>SOLUTION: This capped container 10 comprises a container body 11 for storing stored item generating gas and a cap 13 installed at an opening neck 12 of the container body 11, wherein the cap 13 is provided with a pressure relieving mechanism 14. The pressure releasing mechanism 14 comprises an annular wall 17 concentrically arranged inside an outer circumferential wall 15 of the cap 12 and formed with a ventilation slit 16 extending upward or downward direction to be formed at its circumferential surface, an annular close abutted part 18 sliding upward or downward in respect to the annular wall 17 while being closely contacted with the inner circumferential surface, and an inner pressure limiting means 20 for limiting an operation from a closed state of a discharging passage 19 where the ventilation slit 16 passes until it reaches up to a predetermined pressure while closely contacting the annular close abutted part 18 with a position spaced apart from the ventilation slit 16. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
