Further, when the detachable portion 81 of the lid 6 is attached to the detachable portion 15 of the main body 2, the pressure contact protrusion 30 of the inner facing wall 29 of the main body 2 presses the hanging wall 74 of the lid 6. The pressing stabilizes the state in which the detachable portion 81 of the lid 6 is attached to the detachable portion 15 of the main body 2. Further, when the locking protrusion 83 of the lid-side outer peripheral wall 82 of the lid 6 is pressed against the locking groove 22 of the upper end outer peripheral wall 18 of the main body 2 by the reaction force of the pressing, the lid is pressed against the detachable portion 15 of the main body 2. In addition to the state in which the detachable portion 81 of 6 is attached, the locked state between the detachable portion 81 of the lid 6 and the detachable portion 15 of the main body 2 is strengthened.

As described above, when the upper peripheral wall 19 and the lower peripheral wall 20 are torn in the upper end outer peripheral wall 18 of the lid 6, the upper peripheral wall 19 is separated from the main body 2 and the upper half of the locking groove 22 is lost. Therefore, the locked state between the detachable portion 81 of the lid 6 and the detachable portion 15 of the main body 2 is eliminated. As a result, the user can remove the lid 6 (attached / detached portion 81) from the main body 2 (attached / detached portion 15).

Further, even if the detachable portion 81 of the lid 6 is reattached to the detachable portion 15 of the main body 2, the upper half of the locking groove 22 is already lost in the upper end outer peripheral wall 18 of the lid 6, and the lid 6 is covered. The detachable portion 81 and the detachable portion 15 of the main body 2 do not return to the locked state. Therefore, in the upper end outer peripheral wall 18 of the lid 6, after the upper peripheral wall 19 is separated from the main body 2, the detachable portion 81 of the lid 6 is detachably attached to the detachable portion 15 of the main body 2.
