<P>PROBLEM TO BE SOLVED: To provide a container capable of preventing a stuff filled therein from being ejected or spilled outside when opening the container. <P>SOLUTION: In the container 10, the bottom part 14 of a container part 12 includes a seat part 16a which is formed in a vicinity of the edge of the barrel part 16 and annular in plan view, and a spherical crown part 14a which is curved in a spherical-crown shape with its center forming the lowest portion, and integrally formed with the barrel part. A lid part 30 is fixed to the periphery of an opening part 26 of the barrel part 16 of the container part 12 so as to seal the container part 12 opposite to the spherical crown part 14a of the bottom part 14 of the container 10 while a liquid 392 fills the container part 12, and pressed against the spherical crown part 14a side of the bottom part 14, and joined on the periphery of the opening part 26 of the container 10 while its center is deformed so as to be close to the spherical crown part 14a. In the container part 12, pressurization on the spherical crown part 14a and the lid part 30 is stopped, and a space part 40 between the liquid 392 and the lid part 30 is in an evacuated state by the restoring forces of the lid part 30 and the spherical crown part 14a of the bottom part 14. <P>COPYRIGHT: (C)2011,JPO&INPIT |
