PROBLEM TO BE SOLVED: To perform assembling work efficiently by preventing an operation portion from rotating when an operation mechanism comprising a cover body and the operation portion is assembled to a container main body. SOLUTION: A substantially L-shaped sheet portion 4 (temporary holding portion) is provided at an opening 1d for operation of an operation mechanism formed by fitting a rotary shaft 2a of an operation portion 2 into a rotary bearing 1a of a cover body 1 from below the bearing. When this operation mechanism is assembled to a container main body, the sheet portion 4 is temporarily fixed to the cover body 1 by thin-walled parts 4a of an upper end of the sheet portion 4 and by parts 4c, 4d to be locked of a lower end thereof and, even in the case where the operation portion 2 is intended to be rotated under its own weight with the rotary shaft 2a as a center, a peripheral surface of the operation portion 2 abuts against an inner face of a suspended part 4b to be stopped thereat. When the operation portion 2 is used, all required is to cut off the thin-walled parts 4a to completely remove the sheet portion 4 from the cover body 1, or to remove the parts 4c, 4d from the cover body 1 to rotate the sheet portion 4 upward without cutting off the thin-walled parts 4a. |
