PROBLEM TO BE SOLVED: To provide a lid opening/closing mechanism with which a lid cannot be opened by infants or the like since it always needs a plurality of operations for opening the lid in the state where the lid is closed, and which can prevent the infant or the like from accidentally swallowing contents in a container.SOLUTION: A lid opening/closing mechanism comprises an upper end structure part 2 which is provided in the opening on the upper end of a contents storage part, and a lid part 4 which is provided in the rear part of the upper end structure part via a hinge part. The upper end structure part comprises a storage part side engaging protrusion 22 which is formed of a bent part 22a protruding frontward and bent downward, and a pressing part 23 which is located on the lower side of the storage part side engaging protrusion and is pressed inward. The front part of the lid part is provided with an engaging hole 41 through which the bent part of the storage part side engaging protrusion passes. The upper end structure part includes a belt-like protrusion 21 in an elastic structure which acts so as to push up the lid part in the state where the lid part is closed. In the state where the lid part is pushed up and closed, the bent part is engaged with a lower end portion of the engaging hole, the lid part is pushed down, the pressing part is pressed inward, the bent part passes through the engaging hole to the inner side, and thereby the lid part can be opened upward.SELECTED DRAWING: Figure 3 |
