Description

[Detailed Description of the Invention] The present invention relates to a packaging device that can be used for packaging television receivers.

First, a conventional packaging device will be explained with reference to FIG.

In the figure, 1 is a packaging box made of paperboard such as corrugated paper, and 2
is the body plate, 3 is its top flap, and 4 is its bottom flap.

Inside this packaging box 1, a packaging device 7 such as a television receiver is packaged with cushioning materials 5 and 6 such as styrene foam placed inside the peripheral ridges of the top and bottom, respectively.

However, in such conventional products, when they are stacked in a warehouse in a packaged state and a large force is applied from above, as shown in the top A in the figure, the cushioning material 5 shrinks and the top drops. As a result, the body plate 2 protrudes outward as shown by arrow B, resulting in a very poor packaging appearance.

If the body plate 2 protrudes in this way, the value as a product will be greatly reduced.

Therefore, an object of the present invention is to provide a device that eliminates such conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 2 and 3.

In the figure, 8 is a packaging box made of paperboard such as corrugated paper, and 9
10 is a top flap that is continuous with the body plate 9, and has two sets of opposing flaps arranged in directions different from each other by 90 degrees.

Reference numeral 11 denotes a bottom flap, which is configured similarly to the top flap 10.

This device is characterized in that at least one of the top and bottom of the packaging box 8, here the peripheral edge of the top, is formed into an inclined surface 12.

In order to form such an inclined surface 12, as shown in the developed view of FIG. In addition, a bending auxiliary line 15 is formed on the top flap 10, and the adjacent portion of the top flap 10 is removed in a triangular shape.

That is, the slope 12 is defined between the bending auxiliary line 14 and the bending auxiliary line 15.

Reference numerals 16 and 17 indicate bending auxiliary lines for bending the body plate 9 and bottom flap 11, respectively, and 18 and 19 indicate stela pull driving positions for joining the body plate 9 and the bottom flap 11 to form a box body. be.

The bending auxiliary line 15 is formed by pressing linearly into a groove shape so that the expansion plate 13 can be easily bent.

Then, a cushioning material 20, 21 made of styrofoam or the like is placed inside the peripheral ridge of the packaging box 8, and an object 22 such as a television receiver is packaged.

According to this configuration, when the cushioning material 20 shrinks due to a large force as shown by arrow A being applied from above as shown in FIG. The curved portion of the inclined surface 12 bends outward as shown by the arrow B, and the inner flap 10 moves inward, thereby preventing deformation such as bulging of the body plate 9.

Therefore, the body plate 9 does not protrude outward as in the conventional case.

Moreover, since the deformation on the inclined surface 12 is not so noticeable, there is less risk that the overall appearance of the package will deteriorate.
It is possible to maintain good product value.

In addition, in the illustrated embodiment, only the top part is provided with an inclined surface.
The bottom may also have a sloped surface.

As described above, according to the present invention, by providing an inclined surface in the continuous section from the body of the packaging box to at least the top flap, a large force is applied to the top flap when the packaging box is stacked in a warehouse, etc. Even if the top flap and the sloped surface are deformed, there is no possibility that the deformation of the waist and leg plate portions that would significantly deteriorate the appearance will occur.
