[0008] In view of the above, an object of the present invention is to provide a packaging material capable of packaging one to four commodities (CDs) with the same packaging material.

[0009] In view of the above, an object of the present invention is to provide a packaging material that does not hurt a product during packaging.

[0010] In view of the above, an object of the present invention is to provide a packaging material capable of fixing a product at a predetermined position so that the product does not shift in the packaging material during transportation.

[0011]

According to the invention, the packaging material comprises a quadrilateral bottom surface, four elongated sides connected to the bottom surface, a lid connected to the first side, and a first side. A bent portion connected to the second side opposite to the portion, and extends across the second side and the bent portion and extends in the width direction of the second side and the bent portion. A plurality of bent portions for partitions are formed.

According to the invention, in the wrapping material, each of the partition folds is formed by two cutting lines parallel to each other, and the two cutting lines extend from the boundary between the second side and the bottom. Starting, it traverses the second side and extends a little short of the outer edge of the fold.

Except for A, 23B and 23C, all represent bending lines.

First and second sides 11 and 21 are connected to the two long sides of the bottom 10, and third and fourth sides 31 and 41 are connected to the two short sides of the bottom 10. ing. First
The lid portion 12 is connected to the side portion 11, and the first folded portion 13 is connected to the lid portion 12. First side 11
A second folded portion 22 is connected to a second side portion 21 on the opposite side to the second.

The third side portion 31 has a third folded portion 32
Is connected to the fourth side portion 41 and the fourth folded portion 42
Is connected. Of the four corners of the folded portions 32 and 42, the corners on the lid 12 side are cut off diagonally, as shown by the two-dot chain line in the figure. Triangle cut 3
3, 43 prevent the corresponding part of the inner surface of the lid 12 from being damaged during assembly.

The second side portion 21 and the second folded portion 22 connected to the second side portion 21 are provided with three partition bent portions 23A that straddle the two and extend in the width direction of the two.
23B and 23C are formed. These three partition bending portions 23A, 23B, and 23C
It is formed by a set of parallel cutting lines (solid lines).

Starting from the edge of the second side 21, that is, the connecting line between the second side 21 and the bottom 10, these parallel cutting lines (solid lines) It crosses and extends to the middle of the second folded portion 22, that is, to a position (shown by a broken line) slightly before the outer edge of the second folded portion 22.

Next, the dimensions of each part of these packaging materials will be described. The length of the long side of the bottom 10 is A, and the length of the short side is B
(<A). Assuming that the width of the first side portion 11 is H, the width of the third and fourth side portions 31 and 41 is also H. That is, the size of the first side 11 is A × H, and the size of the third and fourth sides 31 and 41 is B × H. This width dimension H corresponds to the thickness of the packaging material when assembled.
Accordingly, the outer dimensions of the assembled packaging material are A × B × H.

The dimension of the width of the second side 21 is h, so that the dimension of the second side 21 is A × h. This width dimension h is smaller than the width dimension H of the three side parts 11, 31, 41, that is, H> h. The width dimension h of the second side 21 corresponds to the thickness of the CD to be wrapped. The thickness H of the packaging material is larger than the thickness h of the CD because the bundled material such as D
