[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper packaging box provided with a paper buffer piece. In particular, it relates to a paper packaging box equipped with a paper cushioning material that contributes to environmental protection and resource recycling.

[0002]

[Prior art]

 The inventor is not aware of this type of conventional example. As a widely practiced example, foamed plastics such as Styrofoam are adhered inside the four corners of a cardboard box with an adhesive. It is also known that a plurality of corrugated cardboard sheets are laminated and cut into an appropriate size and thickness, and are bonded to the insides of the four corners of a corrugated box.

Although these conventional examples have an advantage that they can be easily used, as the former has become a global problem recently, the disposal of the waste has a decisive effect on the so-called global environment conservation. Depletion of resources is also a problem because it is a major problem and petroleum products.

Further, the latter is made of paper, so that it can be expected to be recycled, and it has an advantage that it can be easily used. However, corrugated paperboard is cut into an appropriate size and thickness and polymerized. Therefore, there was a basic problem that the production process was complicated and lacked the ability to relax.

[Problems to be solved by the device]

 The problem to be solved by this invention is to provide a paper packaging box provided with a paper cushioning piece having excellent cushioning ability and productivity while recycling the product.

[0006]

[Means for Solving the Problems]

 Provide a paper cushion box body and a paper cushioning piece with a convex portion, and attach the opposite side of the convex portion of the paper cushioning piece to the inner side surface of the packaging box body to separate the paper cushioning piece from the packaging box body. A sealed air layer is provided between them to improve the cushioning capacity.

【Example】

 FIG. 1 shows an embodiment of the present invention, and is a perspective view in which paper cushioning pieces 10 are adhered to the insides of the four corners of a cardboard box body 12. The paper cushioning piece 10 according to this embodiment is manufactured by the following device. Compressing and molding uneven products using paper materials by using a press machine, etc. In principle, paper materials do not have spreadability or malleability as is well known, so production is virtually impossible.

Therefore, as a result of various research and development so that the paper material can be spread and malleable within a certain range, the inventor has provided the paper material 16 provided with the corrugated step portion 14 like corrugated paper. Was attempted (see FIG. 2). There is no difficulty in the means for providing such a paper material 16, and as is well known, by passing the paper material between the corrugated rolls of a so-called well-known corrugating machine (not shown), the necessary corrugated step portion 14 is formed. Is easily obtained.

It will be easily understood that such a paper material 16 can be expanded and malleable even if it is pressed particularly at right angles to the corrugated step portion 14.

Therefore, an upper mold 18 and a lower mold 20 are prepared, and both molds 18 and 20 have a mold structure having a shape corresponding to the form of the paper cushioning piece 10 as a product (see FIG. 3). reference).

By inserting the above-described paper material 16 into the molds 18 and 20 and heating and pressing the paper material 16, the paper material 16 is formed into a form having the convex portion 22 (see FIGS. 1 and 4). reference).

In this case, since the paper material 16 is provided with the corrugated step portion 14, the paper material 16 is spread or malleable in a certain direction and is never damaged.

In this way, the convex portion 22 protruding to one side is formed on the paper cushioning piece 10.

Therefore, by using the paper cushioning piece 10 which has not been obtained in the past, the surface on the side opposite to the convex portion 22 is attached to the four corners of the inside of the paper packaging box body 12 with the adhesive 24. Adhere (see Figure 4).

Thus, with the air layer 26 in a sealed state formed between the inside of the paper packaging box body 12 and the paper cushioning piece 10, the paper cushioning piece 10 of the paper packaging box body 12 is formed. It is connected to the inner surface.

In this case, the corrugated stepped portion 14 formed on the paper material 16 is crushed by a pressing machine or the like at the time of molding, but the stepped portion 14 does not surely become flat. A part of it will remain as a ridge 28, though slightly.

Therefore, since the ridge 28 and the inner surface of the paper packaging box main body 12 are not smooth but have a wavy shape, the adhesive function of the adhesive 24 is improved, and the paper cushioning piece 10 is There is an advantage that it is more firmly bonded to the paper packaging box body 12.

In this embodiment, the shape of the convex portion 22 is elongated, but the shape is not limited to such a shape. The shape can be freely set according to the form of the packaged item.

Although the present invention refers to the paper packaging box in principle from the problem of the invention, the application of the paper cushioning piece 10 in the present invention is not limited to the application to the paper packaging box main body 12 but is made of plastics. In principle, it can be applied without limitation to the material of the packaging box (including the box), the packaging box made of wood, the packaging box made of metal, and the packaging box made of metal. In addition, we explained how to attach a paper cushioning piece to the body of a paper packaging box.However, in addition to the box, it can be applied to packaging materials other than the box body, such as grid-shaped partitions that are housed inside the box and frame materials for packaging. The inventor plans to use the paper cushioning piece according to the present invention by adhering it as a mere design change.

Furthermore, in the embodiment, the case where the paper cushioning pieces 10 are adhered to the inside of the four corners of the main body 12 has been described. Of course, the paper cushioning piece 10 is attached to the lid piece, the side piece, and the bottom piece. Needless to say, there is also a plan for bonding.

[0021]

[Effect of device]

 As described above, the present invention has the above-mentioned configuration and therefore has the following advantages. Since a packaging box with a cushioning piece having an air layer between the main body of the paper packaging box and the paper cushioning piece can be obtained, it is possible to use a packaging box with a higher cushioning capacity than previously experienced paper cushioning pieces. You can get a box. Further, since the material of the cushioning piece is paper, the material can be recycled while improving the cushioning function, which can contribute to environmental protection and suppress depletion of resources.
