Reference numeral 33 denotes a fastening band made of polypropylene for tightening each packaging member incorporated around the refrigerator 1 from the outer periphery.

The operation of the first embodiment configured as described above will be described. First, the procedure for assembling the packaging member will be described. After the extending ends 25a, 25b of the side standing walls 25, 26 are bent substantially at right angles to the side standing walls 25, 26, the side standing walls 25, 26 are bent at substantially right angles. The front and rear standing walls 23 and 24 are bent at substantially right angles in the same direction as the side standing walls 25 and 26 to form the box-shaped base plate 9. Next, the rectangular extension surface 30 is bent at a base portion thereof at a substantially right angle inward of the front and rear standing walls 23 and 24 to form a first bent surface 31a. The second bent surface 31b is formed by being bent substantially at a right angle in the direction of the bottom surface 22 so as to be sandwiched therebetween, and the first projecting portion 31 is formed.

Next, the second bent surface 31b of the extension surface 30 is bent substantially at a right angle in the vicinity of the center thereof, and is further bent substantially 180 degrees in the direction opposite to the bending direction, and further bent in the direction opposite to the bending direction. It is bent at a substantially right angle so that this bent surface is on the same plane as the original bent surface, and on the second bent surface 31b, it is almost parallel to the bottom surface 22 of the box-shaped base plate 9 and is directed inward. The second projecting portion 3 having a substantially T-shaped cross section toward it
Form 2 Next, a metal staple 28 is driven into the overlapping portion 27 from the front and rear standing walls 23 and 24.

The first and second projecting portions 31 and 32 of the box-shaped base plate 9 thus formed are provided with bottom cushioning members 10 and 11.
Of the first notch 18 (19) and the second notch 20 (2
1) is inserted and fitted, and the bottom cushioning materials 10 and 11 are connected to the box-shaped base plate 9 to form the packaging base plate 8. At this time, the box-shaped base plate 9 and the bottom cushioning members 10 and 11 are not fixed with an adhesive such as hot melt interposed therebetween.
Next, on the packaging base plate 8 assembled as described above,
The refrigerator 1 is placed. At this time, the legs of the refrigerator 1 fit into the leg recesses 12 and 13 of the bottom cushioning materials 10 and 11, and the base plate of the refrigerator 1 fits into the base plate recesses 16 and 17 of the bottom cushioning materials 10 and 11. Next, the protective bag 2 is placed on the refrigerator 1 from above the top surface 1b of the refrigerator 1, the upper cushioning members 4, 5, and 6 are placed on the top surface 1b from above, and the top cover 7 is passed through the outer case 3. After mounting, a packaging member is formed, and a fastening band 33 is tightened around the outer periphery of the packaging member.

When disassembling the packaging member assembled as described above, first, the fastening band 33 is cut with scissors or the like, and then the top surface cover 7 and the upper cushioning members 4, 5, 6, and 6.
The refrigerator 1 is removed from the packaging base plate 8 by removing the outer case 3 and the protective bag 2 in this order. Thereafter, the bottom cushioning members 10 and 11 are taken out while the front and rear standing walls 23 and 24 of the box-shaped base plate 9 are opened back and forth, and the packaging member is disassembled and separated. At this time, since the bottom cushioning members 10 and 11 and the box-shaped base plate 9 are not bonded and fixed with an adhesive or the like, disassembly and separation are easy.

According to the first embodiment, the box-shaped base plate 9 and the bottom cushioning members 10 and 11 can be securely locked by a simple member, and the bottom cushioning members 10 and 11 can be securely fixed in the vertical and horizontal directions. Can be done. That is, the second protruding portion 32 of the protruding portion 29 and the second notch portion 20 (21) of the bottom cushioning members 10 and 11 are respectively formed on the bottom surface 2 of the box-shaped base plate 9.
The bottom cushioning members 10 and 11 do not move in the vertical direction with respect to the box base plate 9 when they are fitted flush with each other. Also, the side surface of the first protruding portion 31 located on the side standing wall 25, 26 side,
The first buffer 18 is locked flush with the first surface 18a (19a) of the first cutout 18 (19) of the bottom cushioning members 10, 11, so that the first
Is fitted to the first cutout 18 (19) of the bottom cushioning members 10, 11, the bottom cushioning member 10,
11 does not move laterally with respect to the box base plate 9.

For this reason, various impacts during distribution in the manufacturing process, during transportation from a factory to a distribution center and a sales company, and during transportation and handling in a market from a store to a consumer, etc. The base plate 8 is strong and does not break, the bottom cushioning members 10 and 11 are unlikely to come off, and damage to the refrigerator 1 does not occur. In addition, since the box-shaped base plate 9 and the bottom cushioning members 10 and 11 do not need to be fixed with an adhesive, no adhesive is required and the environment is environmentally friendly. The box-shaped base plate 9 and the bottom cushioning members 10 and 11 can be easily removed at the time of disposal and recycling. In the above description, the packaging member of the refrigerator 1 has been described. However, the packaged object is not limited to the refrigerator 1, and functions as a packaging member for other heavy products. .
