00 is performed simultaneously. In addition, 300a shown in FIG. 2 is a pulley which is fitted on the output shaft of the compressor 300, and 300b is an accessory part of the compressor 300.

To do this, first hold both sides of the bottom 1 portion of the corrugated board 100, and fold A on both sides of the bottom 1.
B is once bent downward, and a crease is formed so that the contact piece 8 is easily erected. After that, as shown in FIG. 2, when the compressor 300 is placed at a predetermined position on the bottom surface 1 and the side surfaces 2 and 3 on both left and right sides thereof are bent upward along the fold lines A and B, they face each other. Since the oblique folds H of the contact pieces 8 and the upright assisting pieces 10 that are pressed between the two side surfaces 2 and 3 that are vertically erected are bent upward and the folds A and B are bent downward, respectively. The contact piece 8 naturally rises at a right angle inward toward the side surfaces 2 and 3. Then, in a state where both side surfaces 2 and 3 have been completely erected, the contact edge portions 8a of the contact pieces 8 are in close contact with the left and right sides of the outer peripheral surface of the compressor 300 at two places separated by a predetermined distance. Abutted.

At this time, as shown in FIGS. 2 and 3, a pulley 300a axially fitted to the output shaft of the compressor 300,
The contact pieces 8, 8 are inserted into the gap c between the left and right sides of the compressor body so as to face each other. Therefore, the axial movement of the compressor 300 is reliably prevented.

Subsequently, when the top surfaces 4 and 5 are bent at right angles to each other along the fold lines C and D, the laterally rectangular tubular packing device 200 is folded up. Finally, the locking pieces 6A and 6B protruding from the side end of the upper top surface 4 of the two top surfaces 4 and 5 stacked one above the other are formed in the engagement holes 7 formed in the side surface 3.
Also, a hole b formed after the contact piece 8 is erected (see FIG. 3).
(See), each of the hole edges is fixed, and the above-mentioned rectangular tube shape is fixed, and the work of folding up the packing tool 200 from one corrugated board 100 and the work of packing the compressor 300 simultaneously proceed. You can finish it all at once.

In this state, the finger-holding holes 13 and 14 provided on both top surfaces 4 and 5 are vertically penetrated. Therefore, by putting a hand on the finger-holding holes, there is no fear that the packaging will collapse. Easy to carry.

4 to 6 show another embodiment of the present invention. The difference from the above embodiment lies in the arrangement of the cut-and-raised cut 9 and the cut-and-raised fold G for forming the contact piece 8 from the side surfaces 2 and 3 upright. That is, in the above embodiment, the cut 9 for raising the two contact pieces 8 on the lower side of FIG. 1 and the cut 1 for forming the auxiliary auxiliary piece 10 are formed.
1 overlaps the lower edge of the cardboard 100, respectively. However, in the corrugated board 101 of this embodiment, the vertical width of the corrugated board 101 is somewhat widened toward the lower edge side, and the cut-and-raise cut 9 and the cut 11 for erecting the two lower contact pieces 8 are provided on the upper contact piece. 8 is provided in the same manner.

Therefore, FIG. 2 and FIG. 5 and FIG. 3 and FIG.
As is clear from comparison with each other, the folded packing tool 201
Has the effect of further increasing the structural strength of its rear end (in the figure). In this embodiment, the installation position mark d of the compressor 300 is provided on the bottom surface 1 so that the compressor 300 can be quickly installed at a predetermined correct position. Further, the cut-and-raised fold G is provided with a fold-missing portion e, which serves to strengthen the bent portion of the contact piece 8.

In the above structure, the object of the present invention can be achieved even if the detailed structure is appropriately changed. For example, the uneven shape of the contact edge 8a of the contact piece 8 may be determined so as to conform to the outer peripheral surface shape of various packaged articles. In addition, the number of the contact pieces 8 to be formed, the place where the contact pieces 8 are formed, the height dimension of the contact pieces 8 and the like may be arbitrarily determined according to the size, weight, strength characteristics, and the like of the packaged article. In addition, in each of the above-described embodiments, since the compressor 300 is made tough, the contact pieces 8 are formed only on the left and right side surfaces 2 and 3 of the rectangular tube, but depending on the property of the packaged article, the contact piece 8 may also be formed on the bottom surface 1. A similar contact piece 8 may be formed upright. The sheets 100 and 101 serving as the material of the packing tools 200 and 201 are not limited to corrugated cardboard, and a sheet material of a material most suitable for the properties of the packed article and the transportation method may be selected and used.
