PROBLEM TO BE SOLVED: To provide a tamper-evident property by improving a container lid (2) which includes an inner plug (4) and a lid body (6) and is formed such that: the lid body includes a body part (16) and an outer lid (18); and when the content of a container is consumed, the lid body is rotated with respect to the inner plug, and the outer lid is turned from a closed position to an open position with respect to the body part of the lid body.SOLUTION: In a container lid, there is arranged a tamper-evident piece (38) which has one end connected to the outer peripheral surface of an attachment wall (10) of an inner plug and the other end connected to the outer peripheral surface of a skirt wall (32) of an outer lid, and which has a breakable weakened part (42). In a state in which a lid body is attached to the inner plug as required, and the outer lid is positioned at a closed position with respect to a body part of the lid body, when the lid body is rotated in a prescribed direction with respect to the inner plug, or when the outer lid is turned to an open position with respect to the body part of the lid body, the breakable weakened part of the tamper-evident piece is broken, so that the tamper-evident piece is separated into two parts. |
