PROBLEM TO BE SOLVED: To provide a container lid provided with a rotating force imparting auxiliary member which allows even persons weakened in grip to carry out a plug opening operation and a plug closing operation easily.SOLUTION: A container lid 10 includes a top wall 11 and a cylindrical skirt wall 12 suspended from the peripheral edge of the top wall. In the outer peripheral part of the skirt wall, a plurality of knurl parts 13 for slip prevention which protrude outside the outer peripheral part, extend in the axial direction 10a and are arranged through the circumferential direction. In the upper surface of the top wall, a swollen part 14 consisting of an upper wall 14a and a side wall 14b is formed, and, in the side wall of the swollen part, at least one arc-shaped arm part 16 is provided. The outside diameter 16c of the arm part 16 is smaller than the outside diameter 12c of the skirt wall, and one end 16a of the arm part 16 is hinge-connected to the side wall in a freely rotatable way with a connection part 17. The other end 16b of the arm part 16 is expanded toward the outside of the skirt wall, with the connection part as the reference point, serving as a rotating force imparting auxiliary member on plug opening and plug closing of the container lid. |
