PROBLEM TO BE SOLVED: To provide a partition in a cross shape or the like at a folding carton, and to reinforce the bottom therefor. SOLUTION: A protuberance 28a at the end on one side of a turned-in first partition 24a is engaged with a slit 27i on one 21a of a pair of opposite single walls, and a protuberance 28b at the end on the other side of the turned-in first partition 24a is engaged with a slit 27j on the other 21b of the paired opposite single walls. A second partition 24b is cut and raised from a first part 23a of a bottom 23 while a third partition 24c is cut and raised from a second part 23b of the bottom 23, and holding pieces 25a and 26a are formed at parts 25 and 26 that are not cut nor raised and in continuity with a pair of cut-and-raised opposite single walls 21a and 21b. The holding pieces 25a and 26a support the bottom 23 from the underside while a beltlike part 23c is formed to connect between a first external wall 21c and a second external wall 21d, and the bottom 23 is supported by the beltlike part 23c from the underside. |
