2. Description of the Related Art Conventionally, when a product is stored in a corrugated cardboard container, a synthetic resin foam material such as Styrofoam is placed at four corners of the container having a diameter larger than the outer diameter of the product. It is often done. This synthetic resin foam material effectively buffers the impact on the article to be stored and has excellent resilience, and because it is made of a synthetic resin material, it can be easily molded into a shape that fits the shape of the stored article. Widely used.

Further, instead of the synthetic resin foam material, a cushioning material formed by bending a corrugated cardboard piece is also used.

[0004]

However, at this time when the global environment is a problem, the above-mentioned synthetic resin foam, which is used in large amounts as a packaging material, has a problem in waste disposal. There is a tendency to be restricted regardless of whether it is voluntary or legal. On the other hand, the cushioning material formed by bending a piece of corrugated cardboard is a recycled material of the material itself, and at the same time returns to the soil even if it is discarded,
Further, although it is an excellent packaging material that has a low calorific value even if it is incinerated and does not emit a toxic gas and does not damage the incinerator, it has a drawback that the manufacturing cost is high.

Therefore, in the present invention, in order to solve these problems, by using corrugated cardboard which is a recyclable material, it is possible to cope with the waste disposal problem and to be friendly to the global environment, and at the same time, easily and inexpensively. The purpose is to provide a cushioning material that can be manufactured.

[0006]

In order to achieve the above-mentioned object, the cushioning material of the present invention has a corrugated cushioning material interposed between a packaging container and a storage article accommodated in the packaging container. It is characterized in that a plurality of corrugated cardboards each having a liner attached to the core are preliminarily cut into a shape corresponding to the shape of the stored article, and the cardboards are sequentially attached / laminated. .

Further, a plurality of cardboards may be formed into a plate-like body which can correspond to the shape of the void formed between the packaging container and the stored article when the cardboards are sequentially attached and laminated.

Further, the direction of the corrugation of the core in a plurality of plate-shaped corrugated boards to be adhered / laminated is set to about 9 in the middle of the lamination.
You may change the direction by 0 degree.

Further, the direction of the corrugation of the core in a plurality of plate-shaped corrugated boards to be adhered / laminated is set to about 9 in the middle of the lamination.
The corrugated cardboard may be attached so that the liner is brought into contact with the laminated end surface of the laminated corrugated cardboard while being turned by 0 °.

FIG. 1 shows a first embodiment of the cushioning material of the present invention. In this cushioning material 1, flat liners 3 and 3 on both sides of a core 2 having a corrugation (corrugation) are glued. using a double-faced corrugated board consisting of sticking the cardboard, as shown in FIG. 2, cardboard pieces 4 ₁ of a plurality (16 pieces in this embodiment)
To 4 _16, respectively formed separately, are laminated by bonding these liners 3 comrades.

[0011] The cardboard strip ₄₁ to _16, the stored articles for housing using buffer material 1 of the present invention (not shown), is formed between the container such as a cardboard box (not shown) The voids, that is, the desired shape of the cushioning material, are formed by cutting corrugated cardboard into a plate shape obtained by dividing the shape of the desired cushioning material into 16 layers (corresponding to the number of corrugated cardboard pieces) in the vertical direction. Cardboard pieces ₄₁ to ₁₆ to cut formed in each of the shape generally used press type, the press die can be easily produced not intended large-scale as the synthetic resin molding die.

As described above, after the space formed between the stored article and the storage container is formed as corrugated cardboard pieces 4 ₁ to 4 ₁₆ of a plate-like body which is vertically divided into 16 layers, these are bonded together. By doing so, even if the void has a complicated and intricate shape, it can be easily reproduced in that form.

As a matter of course, in a method in which a plurality of rectangular corrugated cardboard pieces are laminated in advance to form a corrugated cardboard block and the corrugated cardboard block is cut, it is not possible to form a cushioning material having a complicated shape as shown in FIG. It is possible.

FIG. 3 shows a second embodiment of the cushioning material 1 of the present invention. Of the 16 corrugated cardboard pieces 4 ₁ to 4 ₁₆ , the center core 2 of the upper 4 corrugated cardboard pieces 4 ₁ to 4 ₄ is used. The direction of the corrugation of (1) is changed by approximately 90 degrees from the direction of the corrugation of corrugated cardboard pieces 4 ₅ to 4 ₁₆ below this. With this configuration, the insertion direction of the holes in the corrugated fiber core 2 having excellent compressive strength is set to, for example, X.
Since it is possible to position the load on both the axis and the Y axis, the load of the stored article can be received by both the X axis and the Y axis, and the shock can be buffered. As a method of manufacturing the corrugated cardboard pieces 4 ₁ to ₄ 4 in which the direction of the corrugation is changed by approximately 90 degrees, it is only necessary to change the direction of the corrugated board inserted when the corrugated board is cut by 90 degrees.

FIG. 4 shows a third embodiment of the cushioning material 1 of the present invention. In contrast to the cushioning material 1 of the second embodiment described above, a liner is provided on the back surface of the cushioning material 1 on the side of the laminated end surface which is in contact with the storage container. The cardboard piece 5 is attached such that the insertion direction of the hole in the core 2 of the cardboard is the Z-axis direction so as to abut. Since the cushioning material 1 has the directionality of the corrugated board with excellent compressive strength in the three directions of the X axis, the Y axis, and the Z axis, it does not easily collapse even when it is impacted from any direction. It absorbs shock.

Since each of the corrugated cardboard pieces 4 ₁ to 4 ₁₆ has a small diameter, the cushioning material of the present invention can be made by using the normally discarded scraps generated when the corrugated board container is cut and formed. Therefore, it becomes possible to manufacture the cushioning material at low cost while effectively utilizing the resources. Then, it is also possible to adhere the sixteen cardboard pieces ₄₁ to ₁₆ in an automated line.

In each of the above-mentioned embodiments, the double-faced corrugated board in which the liners are adhered to both sides of the core is used, but the present invention is not limited to this, and the core is a double-layered double-layer corrugated cardboard. A double-sided corrugated board or a single-sided corrugated board in which the liner is attached only to one side of the core may be used.

[0018]

According to the cushioning material of the present invention having the above-mentioned structure, a plurality of corrugated cardboards having a corrugated core and a liner attached thereto are preliminarily cut into a shape corresponding to the shape of the stored article. In addition, by sequentially adhering and stacking this, even if the desired shape of the cushioning material is complicated and complicated, it can be easily reproduced and formed. It is possible to provide a cushioning material easily and at a low price by using resources effectively as an alternative to the synthetic resin foam material having a treatment problem and using a corrugated board that is friendly to the global environment.

Further, when a plurality of corrugated cardboards are formed into a plurality of plate shapes which can correspond to the void shape formed between the packaging container and the stored article when the cardboards are sequentially adhered and laminated. In addition, even if the desired shape of the cushioning material is complicated and complicated, it can be easily reproduced by forming it.

In addition, the direction of the corrugation of the core in a plurality of plate-shaped corrugated boards to be adhered / laminated is about 9 in the middle of the lamination.
When it is deflected by 0 degrees, it is possible to provide the insertion direction of the hole in the core of the corrugated cardboard having excellent compressive strength in two directions, so that the load of the stored article can be received in two directions and the impact from the outside can be received. Can be buffered.

Further, the direction of the corrugation of the core in a plurality of plate-shaped corrugated boards to be adhered / laminated is set to about 9 in the middle of the lamination.
When the cardboard is attached so that the liner is in contact with the laminated end face of the laminated corrugated cardboard while being turned by 0 degree, the corrugated fiberboard core having excellent compressive strength has three insertion directions of holes. Therefore, the load of the stored article can be received in all directions, and the shock from the outside can be buffered.
