Here, the top flap 15 of the outer box 14 has an outer plate 16, a top plate 17 and an inner plate 18 sequentially connected from the base end side, and the boundary between the top plate 17, the outer plate 16 and the inner plate 18 has a fixed width. In this structure, the top plates 17 are separated from each other and the adjacent top plates 17 are separated from each other. As shown in FIG. 6, after the articles are stored inside the inner plate 3 of the shock absorber 1, the inner plate 18 is folded back from the outer plate 16. Then, the top plate 17 is alternately inclined in the opposite direction.

In this manner, when the top flap 15 of the outer box 14 is folded back and the cover plate 19 is closed, the bottom pad 10 is provided on the bottom surface of the object to be packed, the wall material 2 is provided on the peripheral surface, and the wall material 2 is provided on the top surface. Since the top flaps 15 keep the distance between the outer wall of the outer box 14 and the packaged object along the top flap 15, the packaged item is reliably protected by a simple packing operation.

Next, a second embodiment of the present invention will be described with reference to FIGS.

The buffer 21 is formed from a cardboard base material as shown in FIG. In this base material, three wall members 22 are arranged in a horizontal direction, and a wall member 23 is continuously provided below the central wall member 22. The wall material 22 has an inner surface plate 24,
The top plate 25 and the outer plate 26 are sequentially provided from the top to the bottom, and the wall member 23 is sequentially provided from the bottom to the top. The inner plate 24 arranged side by side is connected via a folding piece 27. Wall material 22 in the middle of the row
The boundary between the top plate 25 and the inner plate 24 and the outer plate 26 is alternately shifted by a fixed width alternately in the wall material 23 therebelow, and the adjacent top plates 25 are separated. Also, row of wall materials 2
The winding plate 28 and the overlap plate 29 are sequentially provided on the upper edge of the second inner plate 24, the engagement pieces 30 are provided on the outer surface plates 26 on both sides, and the engagement holes 31 are provided on the overlap plate 29. .

In order to assemble the buffer 21 from the above-mentioned base material, first, as shown in FIG.
And the outer plate 26 are opposed to each other, and the top plate 25 is alternately inclined in the opposite direction. Further, in the wall member 22, the winding plate 28 and the overlapping plate 29 are wound, and the engaging piece 30 is bent to be engaged with the engaging hole 31. Next, while folding the folding piece 27,
As shown in FIG. 9, three wall members 22 in a row are bent in a U-shape, and the wall materials 22 and 23 in a column are bent in an L shape so as to follow the lower surface of the wall material 22.

As shown in FIG. 10, two articles 21
Are set facing each other, and the article is inserted inside the U-shaped wall 22 and placed on the wall 23.

The bottom flap 33 and the top flap 34 of the outer box 32 have an outer plate 35, a top plate 36, and an inner plate 37 which are sequentially connected from the base end side. The boundaries are alternately shifted by a constant width, and adjacent top plates 36 are separated. And outer box 3
When the buffer 21 is set on the second flap 3, the bottom flap 33 is folded back, the wall material 23 is sandwiched between the outer surface plate 35 and the inner surface plate 37, and the articles are stored in the outer box 32.
Turn 4 back.

With the folding of the bottom flap 33 and the top flap 34, the top plates 36 are alternately inclined in opposite directions as shown in FIG. And the lid plate 38 of the outer box 32
Is closed, the bottom surface of the object to be packed is supported by the wall material 23 and the bottom flap 33, the wall material 22 extends along the peripheral surface of the object to be packed, and the top flap 34 extends along the top surface. Since the distance between the wall 39, the peripheral wall 40 and the lid plate 38 and the object to be packed is maintained,
The packing object is reliably protected by a simple packing operation.

Next, a third embodiment of the present invention will be described with reference to FIGS.

The buffer 51 is formed from a cardboard base material as shown in FIG. In this base material, three wall materials 52 are arranged in the horizontal direction. In each wall material 52,
An inner surface plate 53 and a top plate 54 and an outer surface plate 55 which are sequentially connected above and below the inner surface plate 53 are provided.
Are connected via. The boundaries of the top plate 54 of each wall material 52 and the inner surface plate 53 and the outer surface plate 55 are alternately shifted by a fixed width, and adjacent top plates 54 are separated.

In order to assemble the buffer body 51 from the above-described base material into the shape shown in FIG. 13, first, the wall material 52 is folded back so that the inner surface plate 53 and the outer surface plate 55 face each other. By this turning, the top plate 54 is alternately inclined in the opposite direction. Next, the three wall members 52 are bent in a U-shape while folding the folding pieces 56.

The bottom pad 61 used together with the buffer 51 is made of a base material as shown in FIG.
In this base material, a leg plate 63 and a folded plate 64 are sequentially provided on both side edges of the bottom plate 62, and the leg plate 63 and the folded plate 64 are sequentially formed inside the bottom plate 62 by a U-shaped cut. The boundaries between the leg plate 63, the bottom plate 62, and the folded plate 64 are alternately shifted by a fixed width, and the adjacent leg plates 63 are separated.

To assemble the bottom pad 61 from the base material into the shape shown in FIG. 15, each folded plate 64 is folded from the bottom plate 62, and the bottom plate 62 and the folded plate 64 are opposed to each other. Due to this turning, the leg plates 63 are alternately inclined in the opposite direction, and are less likely to fall.

In order to pack an article using the cushion 51 and the bottom pad 61, as shown in FIG.
Then, the articles are sequentially inserted inside the U-shaped wall member 52, the bottom pad 61 is sunk into the bottom of the outer box 65, and the articles are placed on the bottom plate 62.

Here, the top flap 66 of the outer box 65 has an outer plate 67, a top plate 68, and an inner plate 69 sequentially connected from the base end side, and a boundary between the top plate 68, the outer plate 67, and the inner plate 69 has a fixed width. The top plates 68 are alternately shifted from each other, and the adjacent top plates 68 are cut off. When articles are stored in the outer box 65 and then the top flap 66 is turned over, the top plates 68 are alternately inclined in the opposite direction.

Then, as shown in FIG. 17, when the cover plate 70 of the outer box 65 is closed, the bottom surface of the packaged object is supported by the bottom pad 61, and the wall material 52 is covered on the peripheral surface of the packaged object by the top. A top flap 66 extends along the surface, and a bottom wall 71 and a peripheral wall 72 of the outer box 65 are provided.
In addition, since the gap between the cover plate 70 and the object to be packed is maintained, the object to be packed is reliably protected by a simple packing operation.

[0028]

As described above, in the shock absorber according to the present invention, each of the bent and connected wall materials is alternately shaped by the top plate inclined in the opposite direction, and the wall material forms a plurality of surfaces of the article to be packed. Is protected, so that the article to be packed can be protected by a simple packing operation.
