Claims

[Scope of Claim for Utility Model Registration] 1. The pedal and the lid are arranged so that when the pedal is depressed, the lid flips up to open the lid, and when the pedal force is released, the lid falls under its own weight and closes. In a device equipped with an interlocking opening/closing mechanism, a buffer means formed by providing an air discharge current limiting means in an airtight telescoping container is connected to a rigid portion of the opening/closing mechanism that reciprocates as the lid opens and closes. The closing speed of the lid body is slowed down by arranging it so that the operating speed when closing is suppressed by the contraction resistance of the telescopic container, and configuring the telescopic container in a contracted state to expand when the lid body is opened. Features: Container lid opening/closing device. 2. The container lid opening/closing device according to claim 1, wherein the expandable container has a restoring force from a contracted state. 3. The container lid opening/closing device according to claim 1 or 2, wherein the expandable container is a bellows container, and the outer periphery of the bellows container is surrounded by a guide body for preventing lateral deformation. 4. The container lid opening/closing device according to claim 1, 2 or 3, wherein the air discharge current limiting means is an air discharge limiting valve. 5. The buffer means includes a bellows container with one end open facing the closed surface, and a compression spring body disposed within the bellows container so as to expand and contract in the same direction as the bellows container. By pressing the closed end, the open end of the bellows container comes into close contact with the closed surface, thereby restricting air discharge, and when the pressing force is released, the close contact is released by the repulsive force of the compression spring body. Item 3. The container lid opening/closing device according to item 3. 6. The expandable container is a bellows container, and the bellows container is located inside the outer bowl-shaped member and the inner bowl-shaped member fitted at the peripheral wall so as to be capable of linear reciprocating movement with respect to the other. 5. The container lid opening/closing device according to claim 1, wherein both ends are arranged so as to be able to expand and contract in the same direction as the linear reciprocating motion, with both ends in contact with the outer bowl-shaped member and the inner bowl-shaped member, respectively. 7. The container lid opening/closing device according to claim 6, wherein the outer bowl-shaped member or the inner bowl-shaped member is biased by a spring body in a direction in which one of them is separated from the other.
