Summary:PROBLEM TO BE SOLVED: To provide a container lid which can be integrally molded out of resin and can be manufactured at a low cost, and also which is convenient in use with operation performed with a single motion. SOLUTION: A bowl-like lid 1 with a center swelling is divided into a movable part 3 at the center and a peripheral fixed part 4 toward a periphery via a dividing line space 2, wherein the movable part 3 comprises a center push 3a at a high position and a plurality of movable pieces 3b extending from the center push 3a in radial directions to be gradually lower. Each movable piece 3b is coupled to the peripheral fixed part 4 by a pair of coupling shafts 5 at both sides of a radial intermediate position, while each movable piece 3b has a resin hinge 7 at an intermediate position between the center push 3a and the coupling shaft 5.
