[Industrial application] This invention is used when a product such as a video camera, which is sensitive to shock and vibration, is housed in an outer box and transported.
The present invention relates to a cushioning material for packaging used as a pedestal or a top holder for products.

[0002]

2. Description of the Related Art FIG. 9 is an example of a conventional cushioning material for packaging.
10 is assembled by assembling the blank shown in FIG.

The blank 21 includes an outer wall 22, a bottom wall 23,
The inner side wall 24, the top wall 25, the inner side wall 24, the bottom wall 23, and the outer side wall 22 are sequentially connected to each other through the fold lines 26, 27, 28, 29, 30 and 31.

Two pieces are provided near each end and the center of the top wall 25.
A total of six rectangular ear pieces 32 are formed.

The fold lines 28 and 29 are mountain-folded and the fold lines 26, 27, 30 and 31 are valley-folded so that the top wall 25 and both bottom walls 23 are horizontal, and both inner side walls 24 and both inner walls 24 are both horizontal. The outer wall 22 and the outer wall 22 are raised vertically.

In this way, the cushioning material for packaging shown in FIG. 9 is assembled, and the ear piece 32 rises vertically with the inner wall 24.

[0007]

However, when the conventional cushioning material for packaging as described above is placed on the object to be packaged and accommodated in the outer box, the upper edges of both outer walls 22 and the ear pieces 32 are Evenly abut the inner surface of the lid of the outer box. Therefore, there is a problem in that the vertical vibration applied during transportation is poorly released, and rather the vertical vibration is transmitted to the packaged object through both outer walls 22 and both inner walls 24 that rise vertically.

[0008] Therefore, an object of the present invention is to provide a cushioning material for packaging which is excellent in shock absorbing action and can be easily assembled when a product sensitive to shock and vibration is housed in an outer box and transported. That is.

[0009]

In order to solve the above-mentioned problems, the present invention proposes a fold line 6 on both sides of a rectangular top wall 2.
Side walls 3 are continuously provided through the fold line 9 at both ends of the top wall 2.
The end wall 4 is continuously provided via the fold line 1 at the end of the side wall 3
1, the side wall of the end wall 4 is connected to the side wall of the end wall 4 via a fold line 12, and a connecting wall 5 connecting the two walls 3 and 4 is continuously provided. The angle between the fold line 9 and the fold line 12 is set to 90 degrees.
The fold line 9 is set to a larger value than the above, the fold lines 9, 11 and 12 are valley-folded, and the fold line 6 is mountain-folded.

[0010]

When the fold lines 9, 11 and 12 are valley-folded and the fold line 6 is mountain-folded, the cushioning material for packaging is assembled.

When vertical vibration is applied to the packaging cushioning material, the end wall 4 rising diagonally above the top wall 2 absorbs the vibration, and the connecting wall 5 connected to the end wall 4 also absorbs the vibration. Vibration is diffused to the outside of both side walls 3 of the cushioning material for packaging.

When lateral vibration is applied to the packaging cushioning material, the connecting wall 5 extending outward from the side walls 3 absorbs the vibration, and the end wall 4 connected to the connecting wall 5 also absorbs the vibration. Vibration is diffused obliquely above the top wall 2 of the packaging cushioning material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIG. 1, a cushioning material 1 for packaging is made of paperboard such as corrugated cardboard, and comprises a top wall 2, a side wall 3, an end wall 4 and a connecting wall 5.

The cushioning material 1 for packaging is formed by assembling the blank shown in FIG. As shown in FIG. 2, the side walls 3 are formed on both sides of the rectangular top wall 2 through fold lines 6 to form the top wall 2.
The end walls 4 are continuously provided at both ends of the through a fold line 9. The end wall 4 is formed at the end of the side wall 3 via a fold line 11.
A connecting wall 5 that connects the both walls 3 and 4 is continuously provided on a side portion of the through a fold line 12.

The angle formed by the fold line 6 and the fold line 11 (reference numeral α in the figure) is set to be smaller than 90 degrees.
Angle formed by the fold line 9 and the fold line 12 (reference numeral β in the figure)
Is set to be larger than 90 degrees.

At the positions close to both ends of the top wall 2, two piercing pieces 7 are formed by partially punching, and a total of four ear pieces 7 are formed. The edge of the ear piece 7 is high on the center side and is inclined so as to gradually decrease toward both ends of the top wall 2. Further, a substantially central portion of the top wall 2 is punched out in a rectangular shape to form a hole 8 for allowing a projection of a product to escape.

When the fold lines 9, 11 and 12 are valley-folded and the fold line 6 is mountain-folded, the cushioning material 1 for packaging shown in FIG. 1 is assembled.

As the side wall 3 stands up, the ear piece 7 is located below the end wall 4, and the inclination of the edge of the ear piece 7 and the rising direction of the end wall 4 are almost the same. Match.

An example of using the cushioning material 1 for packaging thus assembled will be described with reference to FIGS. 3 to 5. Figure 3
As shown in FIG. 3, the cushioning material 1 for packaging is put on the commodity placed on the receiving table 13 and accommodated in the outer box 14.

FIGS. 4 and 5 are views showing the case where a home video camera is housed as a product. Video camera 15
Are placed on the pedestal 13 and housed in the outer box 14. When the packaging cushioning material 1 is put on the video camera 15, as shown in FIG.
Abutting the inner surfaces of both side walls of.

The upper peripheral edge of the video camera 15 contacts the inner walls of both side walls 3 of the packaging cushioning material 1.

When vertical vibration is applied to the outer box 14 in this state, the vibration is absorbed by the end wall 4 of the packaging cushioning material 1 and diffused to both side walls of the outer box 14 through both connecting walls 5. It Further, when the end wall 4 bends to some extent, the end wall 4 is supported from below by the ear piece 7, and the end wall 4 does not fall on the top wall 2.

When left and right vibrations are applied to the outer box 14, the vibrations are absorbed by the connecting walls 5 spreading outward of the side walls 3 of the packaging cushioning material 1, and the end walls connected to the connecting walls 5 are connected. 4 spreads obliquely above the top wall 2 of the packaging cushioning material 1. Therefore, the vibration is not directly transmitted to the video camera 15 through the top wall 2 and both side walls 3.

The cushioning material 1 for packaging can be turned upside down and used as a receiving stand.

6 to 8 show a second embodiment of the cushioning material for packaging according to the present invention. The components having the same configurations and operations as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

The packing cushioning material 1a shown in FIG. 6 is formed by assembling the blank shown in FIG. 7, and shows one of the two cushioning materials that stand up via the ruled line 16 in FIG.

As shown in FIG. 7, a fold line 9a is formed near both ends of the top wall 2 in parallel with the fold line 9 and extends over the top wall 2 and both side walls 3 in parallel with the fold line 9a. Notch 9
b is formed. A semicircular punched hole 17 is provided adjacent to the cut 9b in the top wall 2 portion.

A fold line 18 connecting both ends of the fold line 9a and both ends of the notch 9b is formed on each side wall 3, and the fold line 9a, the notch 9b, and the fold line 1 are formed.
A lower stopper 7a described later is formed by 8.

Further, each end wall 4 is provided with a substantially U-shaped notch 19 on the side of the fold line 9.

Similar to the case of the first embodiment, the fold lines 9, 11 and 12 are valley-folded, and the fold line 6 is mountain-folded to raise each wall. At this time, when the lower stopper 7a is simultaneously pulled down by using the punched hole 17, the fold lines 9a and 18 are bent, and the lower stopper 7a is formed below the top wall 2 as shown in FIG. .

The lower stopper 7a can abut against the end surface of the product to prevent the product from moving in the lateral direction, and both sides of the lower stopper 7a are provided on the side wall 3 as shown in FIGS. 6 and 8 (b). Overlapping on the inside.

Further, a part of the end wall 4 is cut and raised by the notch 19, and the stopper 7b rises as shown in FIGS. 6 and 8. The upper end of this stopper 7b is shown in FIG.
As shown in (a), the position is usually lower than the position of the tip of the end wall 4 by the height indicated by the symbol h. Therefore,
When vertical vibration is applied to the cushioning material 1a for packaging and the end wall 4 bends to some extent, the stopper 7b acts as a cushion instead of the end wall 4, and thus the end wall 4 does not collapse and reach the top wall 2.

[0033]

The packing cushioning material constructed as described above can pull up the left and right end walls 4 and the connecting wall 5 to the top wall 2 and the side wall 3 and at the same time raise both side walls 3.
It can be easily assembled.

Further, the vibration applied to the end wall 4 or the connecting wall 5 is not directly transmitted to the top wall 2 or the side wall 3 and further does not reach the object to be packaged. By exerting the action, it is possible to prevent the packaged object from being damaged or broken.
