    • Valley creases (3) are formed on a surface of a stock material (2) which comprises thin paper. The surface of the stock material (2) is divided by the valley creases (3) into a bottom surface portion (4), which corresponds to a bottom surface portion of a piece of cake, and a side wall (5) which adjoins the bottom surface portion (4). The side wall (5) is formed on its surface with valley creases (6) and mountain creases (7). The valley creases (3, 6) and mountain creases (7) make a container body (1) into a shape of a cup. The respective creases (6, 7) produce a plurality of divided creased pieces (8, 9, 10). The creased pieces (8, 9, 10) are formed with step portions (13) which intersect the valley creases (6) and the mountain creases (7) in a stepwise manner. When a restoring force of the stock material (2) acts on the valley creases (6) and the mountain creases (7), the respective creases (6, 7) tend to unfold but the step portions (13) resist to prevent unfolding.
    • 谷物折痕(3)形成在包含薄纸的原料(2)的表面上。 原材料(2)的表面被谷部折痕(3)分割成与饼块的底面部分相对应的底面部分(4)和与该饼状物相邻的侧壁(5) 底面部分(4)。 侧壁(5)在其表面上形成有谷部折痕(6)和山形折痕(7)。 山谷褶皱(3,6)和山皱(7)将容器体(1)制成杯形。 相应的折痕(6,7)产生多个分开的褶皱件(8,9,10)。 折痕片(8,9,10)形成有阶梯部分(13),其阶梯状地与谷部折痕(6)和山形折痕(7)相交。 当原料(2)的恢复力作用于谷部折痕(6)和山折痕(7)时,各折痕(6,7)倾向于展开,但台阶部分(13)抵抗以防止展开。
