<p>PROBLEM TO BE SOLVED: To efficiently utilize a material and facilitate assembly and disassembly. SOLUTION: The corrugated fiberboard box is kept in shape by wrapping a folding piece 8 extending from a sidewall 15 with an external end plate 5, a frame plate 6 and an internal end plate 7 which constitute an end wall 16. In this case, corrugations of a corrugated fiberboard is inclined by 45 deg., and a corner in a state of a blank is cut slantly. Not only an area of the blank is small but also the blank is of a shape similar to a rectangle, whereby blanks of a plurality of corrugated fiberboard boxes can be arranged so that their legs are adjacent to each other, resulting in efficient use of the material. In addition, the boxes can be assembled by correctly and quickly folding along creases which intersect with the corrugations at an angle. Further, a lower rim of a through hole 14 of the folding piece 8 is cut to be larger than a through hole 13 of the internal end plate 7 on a handle hole 17, thereby forming difference in stages between the through holes 13 and 14. Therefore, a finger can be caught on the difference to swing up the internal end plate 7 for easy disassembly.</p> |
