Abstract

<P>PROBLEM TO BE SOLVED: To provide a packing device which prevents the breakage of an outer box in carrying out load handling work without complicating the structure of the box to offer superior workability in packing an article. <P>SOLUTION: According to the packing device for an outdoor unit of a split type air conditioner, the article 1 is housed together with a lower buffering material 3 and an upper buffering material 5 in a tray-like bottom board 2 with its four sides bent, and is covered with the outer box 8 having an opening on its lower part. A band 11 is put around the exterior of the bottom board 2 and outer box 8 to support the article 1. A fold-back portion 9 is so formed in the middle of each of at least opposite two sides of the four sides of the opening of the outer box 8 that each side is folded back inwardly to form an overlapping portion. Each fold-back portion 9 forms a level difference on each of the two sides of the opening, which gives the opening a double structure to reinforce the outer box 8. In addition, since the opening of the outer box 8, which tends to come in contact with a corner or a pallet of another packing device stacked at a lower tier, is folded back to form the level difference, the opening hardly comes in contact with the corner or pallet upon carrying out load handling work for transportation, such as loading and unloading. <P>COPYRIGHT: (C)2007,JPO&INPIT
