Description

[Detailed explanation of the idea] The present invention relates to a cardboard packaging box.

More specifically, the present invention relates to a cardboard packaging box having a buffer section suitable for packaging relatively large and heavy items such as furniture, housing equipment, and building materials.

Conventionally, corrugated cardboard packaging boxes have generally been made by cutting and bending single-thickness, wide-width corrugated cardboard according to the dimensions of the packaged item.

Therefore, when packing relatively large and heavy items, since cardboard is easily torn, it is recommended to increase the overall thickness of the box and put a protective layer such as foamed polystyrene or cardboard on both ends or both sides of the box. This prevents the package from being damaged during transportation.

However, from the perspective of transportation and storage, it is common for packaged items to be placed upright in a way that takes up as little space as possible, so the front, back, and sides of the packaging box are relatively less susceptible to damage, but rather the top and bottom surfaces of the packaging box are prone to scratches. Packing the entire package in cardboard of the same thickness was wasteful as it was prone to tearing.

In addition, as the price of petroleum products has increased, the cost of expanded polystyrene has also increased, making it too expensive to be used simply as a cushioning material for packaging.

The purpose of the present invention is to provide an inexpensive cardboard packaging box that has a sufficient cushioning effect without using shock absorbing materials at both ends or both sides, and that eliminates unnecessary cardboard as much as possible. It is on offer.

In the present invention, the first inner bending line 10 is placed inside and the outer bending line 11 is placed outside parallel to one side 2 of the square cardboard 1a.
Four second inward bending lines 12, 13, 14.15 are inserted in parallel to the other two opposing sides 4.5, and cuts 12a, 13a, 14a, 15a are made on the outside of the above inward bending lines, respectively. , and bend it 80 degrees inward along the first inward bending line 10 and bend it 90 degrees outward along the outward bending line 11 to form a raised edge 16, and at the same time, form the second inward bending line. 12,13.
two first packaging members formed into a half-box shape by bending inward at 90 degrees along lines 14 and 15;
Insert four third inner fold lines 17.18, 19.20 corresponding to the second inner fold line parallel to the two opposing sides of the rectangular cardboard box 1b having approximately the same width as the packaging member, This cardboard packaging box is characterized in that it mainly consists of a second packaging member that can be wrapped around the packaged item by being bent inwardly by 90 degrees along the third inward bending line.

In the present invention, the corrugated cardboard can be of the commonly used single type with a thickness of about 5 diagonals, or the double type with a thickness of about 1.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a conventional cardboard packaging box in which cardboard of the same thickness is used throughout, and the top and bottom surfaces of the packaging box are prone to scratches and tears.

In the figure, 22 is a stud.

Figures 2 and 3 show an example of the cardboard packaging box of the present invention.
A first inward bending line 10 is placed on the inside parallel to one side 2 of a, and an outward bending line 11 is placed close to the outside.

Four second inner bending lines 12, 13, 14, 15 are inserted in parallel to the other two opposing sides 4, 5.

Furthermore, cuts 12a are formed on the outer sides of the second inner bending lines 12, 13, 14, and 15, respectively.

13a, 14a, and 15a are included.

The rectangular cardboard 1a, that is, the first packaging member is bent inward 180 degrees along the first inward bending line 10, and then bent outward by 180 degrees along the first inward bending line 10.
1, a standing edge 16 is formed by bending it outward by 90 degrees along the second inward bending lines 12, 13, 14. It is formed.

Two first packaging members are required.

The other rectangular cardboard lb, that is, the second packaging member, has approximately the same width as the first packaging member, and corresponds to the second inward bending line parallel to the two opposing sides 6 and 7. Four third internal bending lines 17.1B, 19°20 are inserted.

Then, by bending each tube inward by 90 degrees along the third inward bending line, it becomes a rectangular tube shape and can be wrapped around the packaged item.

To pack using the cardboard packaging box of the present invention, first fold the cardboard 1b around the packaged item by 90 degrees along the third inner fold lines 17, 18, 19, and 20. surrounding.

Next, a half-box-shaped body formed by bending the cardboard 1a is fitted onto the top and bottom of the packaged item surrounded by the cardboard 1b, respectively, and the box-shaped bodies are tightened with two packing bands 21, respectively. The packaging is completed.

The raised edges 16 formed when the cardboard 1a is folded protrude from both the upper and lower ends or both sides of the package, and the raised edges have a structure in which the cardboard is overlapped and wrap around the edges to protect the packaged items. It works effectively as a buffer for

Furthermore, the cardboard 1aib double protects the packaged item at the fitting portion of the first packaging member to the second packaging member.

According to the present invention, the edges of the packaging box, such as the top and bottom surfaces, which are prone to scratches and tears, are formed into a raised edge with a double structure of cardboard, and the packaging part continuous from the raised edge is similarly double-layered. Because of this structure, there is less damage to the packaged items, and the cardboard material can be saved.
