Abstract
Inner folds (3) are defined on the surface of material (2) made of thin paper. The surface of the material (2) is divided by the inner folds (3) between a bottom (4) corresponding to the bottom of cake and a sidewall (5) contacting the bottom (4). Inner folds (6) and outer folds (7) are defined on the surface of the sidewall (5). A container body (1) is shaped like a cup by the inner folds (3, 6) and the outer folds (7). The sidewall is divided into a plurality of bent pieces (8, 9, 10) by the folds (6, 7). A step portion (13) intersecting the inner folds (6) and outer folds (7) to form a difference in level is defined at each bent piece (8, 9, 10). When a restoring force of the material (2) is applied to the inner folds (6) and the outer folds (7), each fold (6, 7) is about to unfold. However, each fold (6, 7) is prevented from unfolding by the step portion (13) as resistance.
