PROBLEM TO BE SOLVED: To easily carry out the setting work for partitions of a corrugated board box and keep the orthogonal crossing state of the partitions in the vertical and the horizontal directions after the setting. SOLUTION: Partitions are constituted of first corrugated boards 12 forming vertical partitions and second corrugated boards 13 forming horizontal partitions 15a, 15b and 15c crossing orthogonally the vertical partitions, and a fitting cut 23b of the second corrugated board 13 is fitted on central cuts 14b formed on the first corrugated board 12 in the state of folding first root folding lines 21a on both ends of the second horizontal partitions 15b and assembled thereon, and then a pair of bottom faces 22a and 22b formed on both faces of the first root folding line 21a are opened on both faces along slope guides 17a and 17b formed on the sections of the partitions and the second corrugated board 13 is folded up, and fitting cuts 23a and 23c formed on a first horizontal partition 15a and a third horizontal partition 15c are set respectively on cuts 14a and 14c on both faces of the first corrugated board 12. |
