When the cushioning member 1 is stored in the outer box 2, the buffer member 1 is supported on the inner wall of the outer box 2 by the upper end surface of the upper right support part 6. The upper end surface of the right storage upper support portion 6 does not need to be always in contact with the inner wall of the outer box 2. Any structure that prevents direct contact between the inner wall 24 and the inner wall may be used.

The upper part 5 of the left stored item is the same as the upper part 6 of the right stored item.

[Explanation of Method of Using Buffer Member] Next, a method of using the buffer member 1 will be described.

As shown in FIG. 4, in a state where the front wall 9 is bent and fixed by the left and right storage object support portions 3 and 4, the process cartridge 24 as the storage object is stored. The process cartridge 24 is inserted into the concave support portions 3f and 4f of the left and right storage object support portions 3 and 4, so that the bottom surface and front and rear surfaces are supported by the left and right storage object support portions 3 and 4 at the cardboard end surface 101. .

At this time, the bottom of the process cartridge 24 is only supported by the left and right storage support portions 3 and 4, and is in a state of being suspended from the bottom plate 13 in a hollow state.

Then, the rear wall 10 is bent upright, and the upper left and right storage support portions 5 and 6 are bent to hold the upper portion of the process cartridge 24. Then, cover 1
1 is folded, so that the process cartridge 24
The cushioning member 1 is assembled in a state of wrapping.

As shown in FIG. 9, the cushioning member 1 is
, The process cartridge 24 is hollowly supported by the cardboard end face 101 while maintaining an appropriate distance from the inner wall of the outer box 2. When the outer boxes 2 are stacked horizontally during transport, the process cartridge 2
4 are supported by the cardboard end face 101 of the right angle support 7 or 8.

Further, even when the outer box 2 is stacked upside down, the process cartridge 24 is supported on the cardboard end face 101 by the upper left and right supports 5 and 6. That is, the process cartridge 24 stored in the outer box 2
Are supported by the cardboard end face 101 at an appropriate distance from the inner wall of the outer box 2 in six directions of front, rear, left and right and up and down.

In the above description, as shown in FIG. 4, in the state where the front wall 9 is bent and fixed by the left and right container support portions 3 and 4, the process cartridge 2 which is the container is stored.
Although an example in which the process cartridge 24 is stored is described above, the present invention is not limited to the above example, and the process cartridge 24 is stored through the opening 27 in a state where the rear wall 10 is bent upright as shown in FIG. May be.

In the present invention, when the process cartridge 24 is taken out from the outer box 2, it is not necessary to take out the buffer member 1 from the outer box 2. In order to remove the process cartridge 24, first, the opening 26 of the outer box 2 is opened, and then, as shown in FIG.
To form an opening 27 in the upper part. Then, by laying the left and right storage article upper support portions 5 and 6, the process cartridge 24 can be pulled upward while the buffer member 1 is stored in the outer box 2.

Further, since the process cartridge 24 can be stored in a state in which the buffer member 1 is stored in the outer box 2, it is easy to put and take out the stored items. Of course, after taking out the buffer member 1 from the inside of the outer box 2, it is needless to say that the lid 11 can be opened to take out the stored items.

As described above, according to the present invention, the stored items can be packed in the outer box 2 via the buffer member 1 formed of a single corrugated cardboard sheet, and the stored items can be securely fixed by the buffer member 1. Can do it.

Also, the storage object support portions (concave support portions 3f, 4f)
) Is not the cardboard surface 102 but the cardboard end surface 101, so that the cardboard surface 102 does not suddenly break. Then, since the cardboard end face 101 gently buckles to buffer, the buffer capacity is easy to predict, and more effective protection can be performed as compared with a conventional packing material using a buffer member.

When the lid 11 is open as shown in FIG. 5, the opening 27 for taking in and out of the stored articles is provided.
Since the direction in which the outer case 2 is opened is the same as the direction in which the outer case 2 is opened, it is possible to take in and out the stored items while the buffer member 1 itself is housed in the outer case 2.

Further, the cushioning member 1 has a one-piece structure made of one corrugated cardboard sheet, and requires less material than a cushioning member having a structure of two or more pieces, so that the cost is reduced and the packing is reduced. In addition, unpacking work is also facilitated.
At the same time, since the cushioning member is made only of the corrugated cardboard sheet, the capacity during transportation can be reduced and recycling can be promoted.

Next, how the shock absorbing member 1 as a packing material obtained as described above absorbs an impact will be described. FIGS. 10 and 11 are side views of the cushioning member 1 when viewed from the direction A and the direction B in FIG. 9, respectively.
The buckling portions of the left and right storage support portions 3 and 4 are shown.

When an impact is applied to the process cartridge 24 from the front and rear and from below, the force is absorbed by the buckling of the cardboard end surfaces 101 of the left and right storage object support portions 3 and 4. When an impact is applied from above the process cartridge 24, the force is absorbed by the buckling of the cardboard end surfaces 101 of the upper left and right support portions 5 and 6. Further, when an impact is applied from the left and right directions of the process cartridge 24 (A and B directions in FIG. 9), the impact is absorbed by the buckling of the cardboard end surfaces of the right-angle support portions 7 and 8.

As described above, the packaging container formed by the outer box 2 and the cushioning member 1 can absorb the force received from any direction by the buckling of the end face of the corrugated cardboard, and can safely protect the stored contents packaged therein. can do. The degree of shock absorption depends on the material of the cardboard and the supporting part of the storage (3, 3).
4, 5, 6, 7, 8).
Therefore, by employing a structure in which the stored object is supported by the plurality of fulcrums in the support portion of the stored object, the impact force can be further reduced.

The cushioning member 1 of the present invention can be put in and taken out of the inside by opening and closing the lid 11, so that it can be recycled again as it is.

Further, at the time of disposal, since the engagement of the engaging portion and the like of the cushioning member 1 is released, the corrugated cardboard sheet becomes one sheet, so that it is not bulky and disposal is easy. Since the corrugated cardboard sheet is mainly made of paper, it can be further used as recycled paper when discarded, and the environment is considered.

[0067]

According to the present invention, the stored article is placed in the proper position of the cushioning member by packing the article into the outer box through the cushioning member supporting portion of the cushioning member made of a cardboard sheet as the end face of the cardboard. It can be fixed securely.
