[0007]

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a corrugated board protector that is formed by bending the unfolded corrugated board shown in FIG. 1 and protects the indoor unit 2 of the cooler by wrapping it. The four plate portions 3 to 6 are provided in a continuous state, and among the four plate portions 3 to 6, the plate portions 4 and 6 having large widths facing each other are provided with chambers at both ends in the length direction of one plate portion 4. Plates 7 and 8 that cover both sides of the machine 2 are connected in series through narrow plates 9 and 10, respectively.

More specifically, plate portions 3 and 5 each having a small width are continuously provided on the opposite long sides of the one plate portion 4, and the remaining long sides of one plate portion 3 of the plate portions 3 and 5 are arranged. On the other hand, a narrow plate portion 11 which bends outward is continuously provided, and the other plate portion 6 of the wider plate portions 4, 6 is continuously provided on the remaining long side of the other plate portion 5. The width of the other plate 6 is the sum of the width of the one plate 4 and the width of the narrow plate 11 described above, and the inner surface of the other plate 6 on the remaining long side. The narrow plate portions 11 are overlapped with each other and are bonded and fixed by an adhesive. In addition, in the connecting portion between the other plate portion 5 and the other plate portion 6, U-shaped notches 12 and 12 are formed on the other plate portion 5 side at appropriate intervals, and the other plate portion 5 is formed. On the other hand, when the other plate portion 6 is bent, the small pieces 13 and 13 which are surrounded by the notches 12 and 12 and are continuously provided on the other plate portion 6 project outward at a right angle to the other plate portion 5. It is configured as follows.

The widths of the plate portions 7 and 8 that cover both sides of the indoor unit 2 are larger than the widths of the plate portions 3 to 6, and both ends of the one plate portion 4 at right angles outwardly. Narrow plate portions 14 which are continuously bent so as to be bent outward at both ends in the longitudinal direction of the narrow plate portions 9 and 10 and the remaining plate portions 3, 5 and 6 which are consecutively bent. , 15, 16, 17, 18, and 19 are overlapped with the inner surfaces near the peripheries of the plate portions 7 and 8 and are bonded and fixed by an adhesive. Specifically, the plate portions 9, 14, 16, 18 are adhesively fixed to the plate portion 7, and the plate portions 10, 15, 17, 19 are adhesively fixed to the plate portion 8. In the plate portions 7 and 8, narrow plate portions 7a, 7b and 8a, 8b are continuously provided on the short sides of the plate portions 7 and 8, and the narrow plate portions 7a, 8a are narrow plate portions. Plate portions 7d and 8d that overlap the outer surfaces of the plate portions 7c and 8c that are connected to the portions 7b and 8b are connected to each other, and the claw pieces 7e and 8e that are formed on the outer plate portions 7d and 8d By engaging with the notches 7f and 8f formed in the portions 7c and 8c, a buffer wall having a space formed between the plate portion 7 and the plate portion 7d and between the plate portions 8 and 8d is configured. There is. The plate portions 7d and 8d are provided with slits 7g and 8g formed in the plate portions 7 and 8 in order to maintain the intervals between the plate portions 7 and 7d and between the plate portions 8 and 8d. Bent pieces 7h and 8h are formed, and plate portions 7 and 8 are also formed with bent pieces 7j and 8j that engage with slits 7i and 8i formed in plate portions 7d and 8d. There is. The bent pieces 7h and 8h are formed by pushing a notch formed in the middle of the plate portions 7d and 8d, and the bent pieces 7j and 8j are formed by the end faces of the plate portions 7 and 8. It is formed by pushing in. Reference numerals 7k and 8k are handle holes formed at positions in the middle of the plate portions 7d and 8d.

In the case of protecting the indoor unit 2 of the cooler by wrapping it with the corrugated board protector 1 having the above-mentioned configuration, a state in which the buffer wall is previously formed by the plate portions 7, 7a to 7d and 8, 8a to 8d Then, the one plate portion 4 is positioned on the lower side, the indoor unit 2 is placed on the one plate portion 4, and the narrow plate portions 9 and 10 are outwardly attached to the one plate portion 4. The plate 9 and 10 are bent at a right angle to the outer surface of the plate 9 and 10 and the inner surface of the plate 7 and 8 is fixed by an adhesive. In that state, by winding the plate portions 3, 5, 6 so as to wrap the indoor unit 2, the narrow plate portions 14, 15, 16, 17, 18, which are continuously provided to the plate portions 3, 5, 6 19 is bent with respect to the plate portions 3, 5 and 6 while being in contact with the corner of the buffer wall, and is adhered and fixed by an adhesive in a state of being in contact with the inner surfaces of the plate portions 7 and 8. Finally, the overlapping portion of the remaining long-side inner surface of the other plate 6 and the narrow plate 11 is adhesively fixed with an adhesive, and then wrapped with this corrugated board protector 1. The indoor unit 2 may be housed inside the cardboard packaging box 20 and the cardboard packaging box 20 may be sealed. In the housed state of the indoor unit 2, the remaining long-side end faces of the other plate portion 6 of the corrugated board protector 1 and the end faces of the small pieces 13, 13 contact the inner surface of the corrugated board box 20. Further, the plate portions 7d and 8d of the buffer wall and the narrow plate portions 9, 14, 16, 18, 10, 15, 17, 17 and 19 also come into contact with the inner surface of the cardboard packaging box 20 to buffer the indoor unit 2. To protect.

By the way, by pushing the bent pieces 7j and 8j formed on the plate portions 7 and 8, the tips of the bent pieces 7j and 8j come to the slits 7i and 8i formed on the plate portions 7d and 8d. The plate portions 7 and 7d are engaged with each other to hold the space between the plate portions 8 and 8d. The formed recess serves as a manual insertion space when the indoor unit 2 is taken out of the corrugated board protector 1, and if the notches for forming the bent pieces 7j and 8j are deeply formed, the indoor unit 2 can be taken out. Will be easier.
