PROBLEM TO BE SOLVED: To enable a circular thin line to be sufficiently easily broken without excessive force by improving the container lid which has a body (2) attached to a container, an outer lid (4) attached to the body, and a circular thin line (22) formed on a clogging wall (6) of the body clogging an opening (78) of the container to define a removal area (24) and the circular thin line is broken by rotating the outer lid attached to the body in a rotation direction for opening.SOLUTION: A cut piece (76) is attached to an outer lid. A circular thin line is partly broken by the work of the cut piece during rotation of the outer lid to a position where the rotation of the outer lid to a body is prevented by a rotation preventing means (38 and 74). After the rotation of the outer lid to a position where the body is blocked, the outer lid is compulsively rotated, and by this the remaining part of the circular thin line is broken. |
