<P>PROBLEM TO BE SOLVED: To obtain a packing structure of a box by which the boxes can be surely carried even under a condition where a plurality of the boxes are piled up in the superimposed direction, and amount of packing materials to be required is reduced, and the packing materials are easily disassembled and recycled. <P>SOLUTION: Support beams 40 and cross beams 42 are fitted on a lower flange 36A of a lower box 10 of a grain drier, and top square boards 48 made of a metal are fitted on an upper flange 38A. Protrusions 54 are formed on these top square boards 48. When a plurality of the lower boxes 10 are piled up in the vertical direction, the protrusions 54 of the lower box 10 of the lower side lap over and enter into the cross beam 42 of the lower box 10 of the upper side. Therefore, even when a plurality of the lower boxes are piled up in the vertical direction, there exists no possibility of shifting of the lower boxes and they can be surely carried. In addition, the amount of the packing material is less in comparison with a case where the whole outer peripheries of the lower boxes 10 are packed with wood frames. Therefore, the packing materials are easily disassembled and recycled. <P>COPYRIGHT: (C)2004,JPO |
