PROBLEM TO BE SOLVED: To prevent a lock claw from protruding to the outside so as to heighten safety by supporting a lid by an axis of rotation at a head end rather than at a root apex, protruding the lock claw upward at the root apex of the lid, making an edge at the root apex of the lid of an opening flawed, and attaching a holding tool for fitting and holding the lock claw to the bottom face of the edge. SOLUTION: On a bottom face of a lid 13 to be provided at a top end opening 12 of a container 11, at a part a little near a head end rather than at a root apex, a pair of right and left brackets 14 are hung. These brackets 14 are axially attached to the right and left walls of the container 11 through an axis of rotation 15. On the bottom of the container 11, a partition 18 is arranged at the back side of the axis of rotation 15, and a containing section 19 is partitioned at the head end of the lid 13 rather than at the partition 18. A lock claw 16 is formed at the root apex of the lid 13 in a manner curving upward. An edge 12A at the root apex of the lid 13 of the opening 12 is formed into a flawed shape. On the bottom face of the edge 12A, a holding tool 17 for fitting and holding the claw 16 is attached. Further, an edge 12B at the head end of the lid 13 of the opening 12 is recessed downward so as to make a step. To the edge 12B, an elastic body 20 which receives the bottom face of the head end of the lid 13 is attached. |
