The second rectangular portion 9 is separated from the first rectangular portion 4 by a cutting line 12, leaving the connection portion 11.
[0013] A third rectangular portion 14 having a rectangular shape is connected to the opposite side of the second rectangular portion 9 from the first rectangular portion 4 via a third folding line 13. The two third folding lines 13 are parallel to each other. The third folding line 13 is formed at a midpoint in the longitudinal direction of the third rectangular portion 14. The third folding line 13 is formed at the same position as the second folding line 8 with respect to the longitudinal position of the third rectangular portion 14. A cut line 15 is formed so as to connect the ends of the two third folding lines 13 to each other. The cut line 15 is formed longer than the distance between the two third folding lines 13. The area surrounded by the two third folding lines 13 and the cut line 15 forms a connection portion 16. The third rectangular portion 14 is separated from the second rectangular portion 9 by a cutting line 17, leaving the connection portion 16. A rectangular cutout 22 is formed at each of both longitudinal ends of the boundary between the second rectangular portion 9 and the third rectangular portion 14 .
[0014] A fourth rectangular portion 19 is connected to the third rectangular portion 14 on the opposite side to the second rectangular portion 9 via a fourth folding line 18. A through-hole 20 is formed in the middle of the fourth folding line 18. The through-hole 20 is formed at the same position as the second folding line 8 and the third folding line 13 in the longitudinal direction of the fourth rectangular portion 19. A through-hole 21 smaller than the through-hole 20 is formed at the midpoint of the fourth folding line 18. The fourth folding line 18 is connected from one end to the other end of the fourth rectangular portion 19 except for the positions of the through-holes 20 and 21. The fourth folding line 18 is in a state where the liner on the front side and the corrugated core are cut and only the liner on the back side is connected. A rectangular cutout 23 is formed at the corner of the fourth rectangular portion 19.
[0015] A circular hole 24 is formed in the center of the cardboard base 2. A T-shaped cut piece 25 is formed between the circular hole 24 and the cutting line 7.

The long side of the first rectangular part 4 and the long side of the second rectangular part 9 are separated, leaving the connecting part 11. The long side of the second rectangular part 9 and the long side of the third rectangular part 14 are separated, leaving the connecting part 16. With this configuration, the adhesion between the rectangular parts is increased, so that the laminated corrugated board section 27 having excellent integrity can be formed. Such a laminated corrugated board section 27 has excellent shock absorption properties, so that the logistics quality is improved. In addition, the assembly is easy, so that the workability is improved. Furthermore, since it is made of only cardboard, separation at the time of disposal is not required, so that the disposability is improved.
[0019] Moreover, in this embodiment, the stacked corrugated cardboard section 27 is formed by further overlapping the fourth rectangular section 19 connected to the third rectangular section 14 via the fourth folding line 18. Moreover, in this embodiment, the stacked corrugated cardboard section 27 is provided on both ends of the corrugated cardboard base section 2. This further improves the shock absorption. Moreover, in this embodiment, the T-shaped cutout pieces 25 are raised and fitted into the engagement holes 26, so that the shape of the stacked corrugated cardboard section 27 can be more reliably maintained.
[0020] 9, in this embodiment, by providing notches 22 and 23, a notch is formed at the end of stacked cardboard section 27 by connection section 6. As a result, in this embodiment, the cardboard sheet does not tear when folded and can be smoothly created, and the integrity of stacked cardboard section 27 is increased, and stacked cardboard section 27 is stabilized on cardboard base section 2 and is less likely to shift sideways, improving product retention and improving transportation quality.
[0021] Also, connecting portion 11 and through-hole 20 form a recess in the side of stacked cardboard portion 27. Also, connecting portion 16 forms a recess in the side of stacked cardboard portion 27. As a result, in this embodiment, the cardboard sheets do not tear when folded and can be created smoothly, the integrity of stacked cardboard portion 27 is increased, stacked cardboard portion 27 is stabilized on cardboard base portion 2 and is less likely to shift sideways, improving product retention and transport quality.
[0022] Furthermore, the cushioning member 28 of this embodiment is formed by folding one cardboard sheet, which reduces the number of parts, reduces costs, and improves disposability.
[0023] 10 and 11 are perspective views showing the cushioning member 28 and bottom tray 29 according to the first embodiment. As shown in FIG. 10, the packaging device of the present embodiment further includes a bottom tray 29. The bottom tray 29 has a plurality of rectangular cutout pieces 30 formed therein. The cushioning member 28 is placed on the bottom tray 29. As shown in FIG. 11, the cutout pieces 30 are raised and contact the side surface of the stacked cardboard section 27. The cutout pieces 30 and the stacked cardboard section 27 may be glued together. With this configuration, the cushioning member 28 can be easily placed at an appropriate position in the center of the bottom tray 29.
[0024] FIG. 12 is an exploded perspective view of the packaging device according to the first embodiment. FIG. 13 is a perspective view showing the packaging device shown in FIG. 12 in an assembled state. As shown in FIG. 12, the packaging device 31 of this embodiment includes a side holder 32 that covers the side surface of the product 90, a top cap 33 that covers the top surface of the product 90, and a band 34 that is wrapped around the bottom tray 29 and the top cap 33 and fastened. The product 90 in the illustrated example is a hydraulic ventilation fan. The product 90 has four legs 91. The four legs 91 are placed against the top surface of the stacked corrugated board section 27 to fully support the load. At this time, there is no part on the side holder 32 side that supports the product 90, and the load is not supported at all. With this configuration, when the product is dropped and impacted, the stacked corrugated board section 27 accurately absorbs the impact, and there is no reaction force from the side holder 32, so that no impact stress is applied to the product 90 side, and no product deformation occurs. Furthermore, since there is no part that supports the load of the side holder 32, the number of parts is reduced, and workability and disposability are improved.
