Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a cushion body used as a cushioning material when packing and transporting electronic equipment, precision equipment, glass products, ceramics, and the like.

[0002]

[Prior art]

 When packing and transporting fragile items such as electronic devices, precision instruments, glass products, and ceramics, transport the package between the packing box and the transported product so that the transported product will not be damaged by vibration, impact, etc. applied during transport. Many cushion pieces and cushion bodies are interposed as cushioning materials.

Conventionally, as a cushion body, a polystyrene foam, a buffer sheet having a large number of hemispherical air chambers between two resin sheets, a foamed resin chip, wood chips, and the like have been used. After unpacking and removing the conveyed product from the packing box, the cushion is no longer needed and is discarded as garbage.

[0004]

[Problems to be solved by the invention]

 However, burning styrene foam, foamed resin chips, and resin sheets as cushions that have become garbage generates harmful gases to the human body during incineration, which poses a pollution problem. Although wood debris and the like do not generate harmful gases even when incinerated, they are expensive and are easily scattered, which is inconvenient for storage, etc., and when used in large quantities, causes a social problem of wasting forest resources. .

[0005] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to make it possible to produce at low cost without causing a pollution problem even if it is incinerated after use. An object of the present invention is to provide a cushion body that enables the effective use of rice husks that have been discarded without being used.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that the first and second ends of the main body are made of corrugated cardboard and have a cross section formed into a flat hollow rectangular cylindrical shape by opposed wide side faces and opposed narrow side faces. An opening is formed in the main body, and one or a plurality of bending lines are provided on both narrow side surfaces of the main body in parallel with the corners, and rice hulls are enclosed inside and formed separately from the main body. The cushion member is constituted by inserting a cushion member made of a paper wrapper from the opening of the main body so as to be insertable and removable. When a vertical pressing force is applied to the wide side surface of the main body, the main body is deformed by bending from the bending line formed on the narrow side surface, and the internal cushion member receives the pressing force. The cushioning property is increased by the action of both of the members. The second aspect is made of corrugated cardboard, and is bent in parallel with the corrugated portion of the core, so that the cross section is formed into a flat hollow rectangular tube shape by opposing wide side surfaces and opposing narrow side surfaces. An opening is formed at both ends of the main body, and one or a plurality of bend lines are provided on both narrow side surfaces of the main body in parallel with the wavy portion, and are formed separately from the main body. The present invention is characterized in that a cushion member made of a paper wrapper in which rice hulls are enclosed is inserted removably from the opening of the main body to form a cushion body. By folding the corrugated paper parallel to the corrugated portion of its core, the main body can be easily and accurately bent at a right angle.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention. FIG. 1 is a perspective view of a cushion body, FIG. 2 is a cross-sectional view of the cushion body, FIG. 3 is a development view of a main body, and FIG. It is. For example, when packing and transporting fragile items such as electronic devices, precision instruments, glass products, and pottery, the cushion body 1 is packed so that the conveyed items are not damaged by vibrations, impacts, etc. applied during transportation. It is interposed as a cushioning material between the box and the conveyed goods.

As shown in FIGS. 1 to 3, the cushion body 1 includes a cushion 3 formed by folding a corrugated paperboard 2 and forming a main body 3 and a kraft paper 5 enclosing rice hulls 4. And a member 6. As shown in FIG. 3, the corrugated paperboard 2 comprises a corrugated sheet 7 having a middle step, that is, a corrugated portion 7a, and a surface sheet 8 adhered to both sides or one surface of the corrugated sheet 7. It has a rectangular shape that is long in the orthogonal direction.

At one end of the corrugated paper 2 in the longitudinal direction, a narrow bonding surface 9 is provided by a fold line 10 a provided along the wavy portion 7 a. The wide side faces 11a, 11b and the narrow side faces 12a, 12b are alternately provided toward the other end of the corrugated paper 2 by fold lines 10b, 10c, 10d parallel to the fold line 10a. One or a plurality of bend lines 13 are formed along the corrugated portion 7a in the widthwise intermediate portions of the narrow side surfaces 12a and 12b. The kinking line 13 is an extremely fine groove formed by scribing means, pressing means or flawing means, and is weaker in strength than the other portions of the narrow side surfaces 12a and 12b. Is formed so that it can be broken first when added.

The fold lines 10 a, 10 b, 10 c, and 10 d of the corrugated paperboard 2 are successively folded at substantially right angles in a mountain direction, and the bonding surface 9 is adhered to the inside of the narrow side surface 12 b with an adhesive or the like, thereby forming a flat hollow angle. A cylindrical main body 3 is formed. Therefore, a hollow portion 14 is formed inside the main body 3 and openings 15 are formed at both ends. In this case, since the fold lines 10a to 10d are formed along the corrugated portion 7a of the corrugated paperboard 2, they can be bent easily and accurately, and the end face of the opening 15 is oriented in a direction orthogonal to the corrugated portion 7a. Since the cut surface has a corrugated surface, the corrugated sheet 7 is less likely to be frayed and has a structure in which the strength of the end surface increases.

As described above, the cushion member 6 is formed by enclosing the rice hulls 4 in the wrapping bag 5 made of kraft paper, and can be inserted into and removed from the hollow portion 14 through the opening 15 of the main body 3. The filling amount of the rice husk 4 is adjusted so that the cushion member 6 does not easily fall off from the pad. The rice husk 4 has been conventionally discarded without being used at all, but is characterized by its light weight, cushioning effect, and effective use of waste.

FIG. 4 shows a state of use of the cushion body 1, and a conveyed article 17 (for example, a fragile article such as an electronic device, a precision instrument, a glass product, and a ceramic), which is stored in a packing box 16, and a package. The cushion body 1 is interposed between the box 16 and protects the conveyed article 17 from vibration, impact, and the like applied during transportation. That is, when the pressing force W is applied from above the packing box 16 during transportation, the narrow side surfaces 12a and 12b receive the vertical pressure via the wide side surfaces 11a and 11b of the cushion body 1, but the narrow side surfaces 12a , 12b are formed with a kinking line 13, so that the narrow side surfaces 12a, 12b firstly fold outward at the kinking line 13 as shown by a two-dot chain line in FIG. The deformation absorbs the pressure, and then the cushion member 6 inside the main body 3 deforms to absorb the pressure. Therefore, the transported goods 17 can be protected by the cushion effect of both the main body 3 and the cushion member 6.

Although the case where the pressing force W is applied from above the packing box 16 has been described, the same applies to the case where the pressing force W is applied from the side or below the packing box 16. Further, in the above embodiment, the main body 3 is formed by folding the corrugated paperboard 2 at the fold lines 10a to 10d along the corrugated portion 7a of the core. However, the corrugated paper 2 is folded in a direction intersecting the corrugated portion 7a. The main body 3 may be formed.

Although the cushion body 1 can be used many times, the main body 3 and the cushion member 6 are separate bodies. Therefore, if the main body 3 is damaged, only the main body 3 needs to be replaced with a new one. The same applies to the member 6. In addition, even if the damaged main body 3 and cushion member 6 are incinerated, there is no problem in terms of pollution.

[0015]

[Effect of the invention]

 As described above, according to the present invention, the production is simple, the cost can be reduced, and the cushioning effect of both the main body having the kinking line and the cushion member has a sufficient cushioning effect. This gives a cushioned body. Furthermore, since the cushion material is manufactured by enclosing the rice husk in a wrapper, the rice hull does not scatter around when packing and unpacking, it is lightweight and easy to handle, and waste can be effectively used. In addition, there is an effect that incineration is sufficient if it becomes unnecessary, and there is no possibility of causing a pollution problem.
