Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard packaging box for packaging electronic devices and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 29 or 30, a corner cushioning material 81, 85 made of expanded polystyrene, for example, is provided at the bottom corner of an A-1 type (0201 type) conforming to the JIS standard and a packaging box 80. Is placed and the product (electronic device) 20 is placed thereon, and an upper pad 82 that forms a cushioning action with expanded polystyrene or the like is further placed on the electronic device 20, or a corner cushioning material 86 is also provided at the upper corner. Was placed and the product was packaged.

Further, as shown in FIG. 31, a cushioning material 87 formed of expanded polystyrene or the like is provided on both sides of the product 20,
There is also a method in which the product is packaged by attaching 88 and storing it in the packaging box 80.

By the way, in recent years, due to the problem of environmental protection, it is inevitable to reduce the use of expanded polystyrene or to switch to alternative materials.

Therefore, as a substitute material for expanded polystyrene or the like, corrugated cardboard is processed to form buffer pads 82 or corner buffer materials 81, 85, 86, and the buffer pad 82 is formed.
Alternatively, a packaging body has been proposed in which the product is stored in the packaging box 80 by using the corner cushioning materials 81, 85, 86.

[0006]

However, the packaging body in which the cushioning materials 81, 85, 86 of the above-mentioned prior art are formed and the product is packaged by using the cushioning material 81, 85, 86 is the packaging box 80 and the cushioning material 81,
Since 85 and 86 are separate pieces, there is a problem that storage management is required and the packaging material cost increases.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a corrugated cardboard packaging box having a cushioning action from one corrugated cardboard sheet.

[0008]

To achieve this object, a corrugated cardboard packaging box of the present invention comprises an upper lid, a lower lid, and a side plate having four sides, two upper buffer portions and two lower buffer portions. Is characterized by being made of one corrugated cardboard sheet.

In order to achieve this object, in the corrugated cardboard packaging box of the present invention, at least the lower cushioning portion is connected to two of the side plates through first folds, respectively, and the lower cushioning portion is provided. Each of the parts has a second fold and a third fold for folding the lower cushion into the box,
Between the second fold and the third fold, two cuts are provided in a direction perpendicular to the fold and the second fold.
Between the first fold and the third fold, a fourth fold provided between one side edge and one cut, and a fourth fold provided between the other side edge and the other cut. 5 folds are provided, and between one end of the one cut and one end of the other cut, and between the other end of the one cut and the other end of the other cut, respectively. A sixth fold line and a seventh fold line are provided, and a reverse fold line is provided at a substantially central portion between the one cut line and the other cut line.

In order to achieve this object, in the corrugated cardboard packaging box of the present invention, each of the upper cushioning portions is connected to the other two of the side plates through the eighth folds, and , Each of the upper cushioning parts is folded substantially in parallel with the eighth folding line to form a cubical cushioning structure by folding the upper cushioning part into the box and forming ninth, tenth, and eleventh folding lines. It is characterized by having.

Further, in order to achieve this object, the corrugated cardboard packaging box of the present invention is characterized in that each of the two upper buffer portions is formed in the same manner as the lower buffer portion.

[0012]

By constructing the corrugated cardboard packaging box of the present invention as defined in claim 1, since a packaging box having a cushioning action can be assembled from a single corrugated cardboard sheet, an inexpensive packaging box can be provided. .

According to the cardboard-made packaging box of the present invention, the lower cushioning portion is provided inside the box along the first, second, third, fourth and fifth folds. By folding and folding the portion surrounded by the two cuts and the sixth and seventh folds at the same time in a mountain shape around the reverse fold, the lower part and the side surface of the packaged object such as the electronic device. It is possible to form a packaged object receiving structure for receiving a part of.

According to the third aspect of the cardboard packaging box of the present invention, the upper cushion portion is folded inside the box along the eighth, ninth, tenth and eleventh folds. Thus, it is possible to form a cushioning structure that suppresses the upper portion of the packaged object such as an electronic device.

Further, by constructing the corrugated cardboard packaging box of the present invention as defined in claim 4, since the upper cushioning portion and the lower cushioning portion are formed in the same manner, the cushioning portion for cushioning all corners of the packaged object at the same time. The structure can be formed.
