    • A method is provided of calculating a development plan of a paper container of deep bottom integrally formed from a single-sheet blank. An annular rule line 6 constituting a regular polygonal shape is formed at the center of a single-sheet blank to constitute the bottom face of the paper container, and divided faces 5 to constitute the outside of the peripheral face of the paper container are formed on the outside of the annular rule line 6. The blank portions between the divided faces 5 constitute inner pleated faces 4. Each of the blank portions is folded downwards along the rule line 7 and folded upwards along the line 9, so that the blank portion is folded to define two triangles 8 with an angle &phgr; and the overlapping portions thus obtained constitute an inner wall face 4. The lateral edges of the divided faces 5 are brought together by folding up the annular rule line 6 while folding the inner pleated faces 4 in two along the lines of symmetry 7 and 9, and the inner pleated faces are overlapped onto the divided faces, whereby a paper container is manufactured.
    • 提供一种计算从单张纸一体形成的深底纸纸容器的显影方案的方法。 构成规则多边形形状的环形规则线6形成在单张坯料的中心,以构成纸容器的底面,并且在纸容器的周面的外侧形成分隔面5 分隔面5之间的空白部分构成内部打褶面4.每个坯件沿着规则线7向下折叠并沿着线9向上折叠,使得坯件部分为 折叠以限定具有角度phi的两个三角形8,并且由此获得的重叠部分构成内壁面4.通过折叠环形规则线6将分开的面5的侧边缘折叠在一起,同时将内部褶皱面4折叠 沿着对称线7和9的两个,并且内部褶皱面重叠在分开的面上,由此制造纸容器。
