PROBLEM TO BE SOLVED: To provide a lid for a fitting container which has a thickness reduced at a part other than a fit portion, and has a reduced material cost.SOLUTION: A lid 10 includes a peripheral edge part 11 and a center part 12. The peripheral edge part 11 is molded from a first synthetic resin sheet, and has a fit portion 11a on the outer edge, and an opening 11b at the center. The center part 12 is molded from a second synthetic resin sheet, and has a bent portion 12a on the outer edge. The fit portion 11a at the peripheral edge part 11 and a bent portion 12a at the center part 12 are bonded to each other such that the fit portion and the bent portion are superposed each other. The second synthetic resin sheet has a thickness smaller than that of the first synthetic resin sheet. The thickness at the center part 12 is smaller than that at the peripheral edge part 11 including the fit portion 11a requiring a thickness equal to or larger than a certain thickness, so that the amount of synthetic resin material is reduced and material cost is reduced, as compared with a lid having a uniform thickness as a whole. |
