The invention comprises a lid configured to close the open end of a container, wherein the lid comprises a track disposed at least partially circumferentially within a peripheral portion of the lid, at least one insertion point within the track, and at least one retention region within the track. A ring is disposed circumferentially about the container, wherein the ring comprises at least one post which is configured to be inserted into and removed from the at least one insertion point and retained within the retention region. At least one of the ring and the lid are circumferentially rotatable between a locked position, wherein the at least one post is within the at least one retention region and an unlocked position, wherein the at least one post is within the at least one insertion point.

The invention discloses a locking structure of a cup. The locking structure comprises a cup body and a cup cover. The cup body is provided with a first buckle, and the cup cover is provided with a second buckle adaptive to the first buckle. The locking structure further comprises a lock catch which is movably arranged on the cup cover up and down. The lock catch is provided with a bolt. Correspondingly, the cup body is provided with a bolt hole adaptive to the bolt. The cup cover rotates on the cup body, so that the first buckle and the second buckle are matched. When aligned, the bolt falls into the bolt hole, thereby realizing rotary locking.

A cap-type synthetic resin container lid (2), which can be removed sufficiently easily from a mouth-neck section (38) of a container without requiring great force and, even after removal from the mouth-neck section (38) of the container, continues to be kept integral without being partly separated to form a scrap piece, is provided.

The container lid (2) includes thin-walled inversion pieces (18) arranged at intervals in the circumferential direction and extending upward beyond a top panel wall (4) from the lower ends of the thin-walled inversion pieces, the lower ends being connected to the outer peripheral surface of a skirt wall (6) or to the boundary part between the outer peripheral surface of the skirt wall (6) and the upper surface of the top panel wall (4); a restraint wall (20) connected to the upper ends of the thin-walled inversion pieces (18) and having a specific site (22) in the circumferential direction, the specific site being either split, or being defined by a breakable weakened section (24); and an operating section (30) connected to the outer peripheral surface of the skirt wall (6) via a connecting piece (28) extending out radially from the outer peripheral surface of the skirt wall (6) at a position in alignment with the specific site (22). Locked projections (26) and locking projections (36) are disposed in the restraint wall (20) and the connecting piece (28), respectively, to collaborate in restricting the expansion of the restraint wall (20).
