<P>PROBLEM TO BE SOLVED: To provide a sealing structure of a container which surely seals the container and enables even a powerless person to easily open the lid. <P>SOLUTION: The sealing structure includes: an inner lid 62 which tightly adheres to the opening of a container 50 through a seal member 55; and an outer lid 64 which moves closer to and away from an inner lid 62 and is connected facing the inner lid 62. The outer lid 64 includes an elastic member 80 for exhibiting an energizing force in the direction to be away from the inner lid 62 positioned between the outer lid 64 and the inner lid 62 and the outer lid 64 is freely rotatable relative to the inner lid 62. The container 50 includes a groove 57 formed in parallel to the rotating direction. The outer lid 64 includes a locking part 82 which is inserted in the groove 57 to be locked when the inner lid 62 is placed on the opening and rotated in a condition where the outer lid 64 is moved closer to the inner lid 62 side. The width of the groove 57 is larger than the width of the locking part 82 corresponding to the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
