PROBLEM TO BE SOLVED: To provide a container lid which can reliably open/close its spout by a simple operation, simple in structure, manufactured at relatively low cost, and easy in sanitary control.SOLUTION: The lid 1 is integrally formed of silicone rubber, and includes an annular fitting part 3, an annular hood part 4, a canopy part 5, and a pick-up part 6 projected upwardly from an upper surface of the canopy part 5. The fitting part 3 is hermetically fitted to an inner circumference of an opening part 2a of a container. The hood part 4 has a base edge which is continuous to an upper edge of the fitting part 3, and extends upwardly in a substantially conical cylindrical and upwardly broadened shape. The canopy part 5 has its base edge which is continuous to an inner circumferential surface of the hood part 4 in a bendable manner, and expands upwardly in a dome shape to cover an upper part of the opening part 2a of the container 2 in a normal state. When its center part is depressed downwardly, it expands downwardly with its base edge as a boundary. The canopy part 5 has a cutout part 8 forming a spout 9 on a base end. By pushing/pulling the canopy part 5 in the vertical direction while holding the pickup part 6, the swelling direction is inverted in the vertical direction, and the spout 9 is opened/closed thereby. |
