[Industrial applications]

 TECHNICAL FIELD The present invention relates to a cushioning material used for packing objects to be packed such as products.

[0002]

[Prior art]

 Conventionally, chemical products made of petroleum such as Styrofoam have been used as cushioning materials for all products such as home electric appliances, precision instruments, chemicals, and miscellaneous goods. Since foamed styrol and the like have excellent cushioning properties, it is possible to protect the object to be packed, that is, the product, from vibrations and shocks during transportation.

However, a chemical product made from petroleum has a problem in treatment after use. Immediately, chemical products made from oil will not rot even if buried in the soil. On the other hand, when burned, black smoke and harmful gases are generated, and the incinerator wall is damaged due to incineration at extremely high temperatures, causing serious pollution problems.

From this point of view, a packaging method has been considered in which a piece of corrugated cardboard is inserted into a gap between the object to be packed and the packing material to reduce vibration, shock, etc. of the object to be packed during transportation.

[0005]

[Problems to be solved by the device]

 However, the piece of corrugated cardboard could not successfully fix and protect the object to be packed. That is, the object to be packed may be displaced due to vibration or shock during transportation, and it may not be placed upright, which may damage the object to be packed.

Therefore, an object of the present invention is to solve the above problems, and to provide a cushioning material which does not pollute the environment and protects an object to be packed from vibration and impact.

[0007]

[Means for Solving the Problems]

 The corrugated cardboard cushioning material of the present invention comprises a corrugated cardboard wound in a tubular shape, one or more cuts formed in a part of the corrugated board, and one side of which is substantially perpendicular to the axial direction with the cut as a boundary. It is characterized in that it is provided with a concave portion which is depressed into.

[0008]

[Action]

 According to the corrugated cardboard core cushioning material of the present invention, it is possible to properly support and cushion the article to be packaged by fitting the article to be packaged between the concave portion and the cylindrical portion which is not depressed. That is, in the object to be packed, the vibration and shock in the axial direction of the corrugated cardboard cushioning material are buffered by the undepressed cylindrical portion. Further, vibration and impact in the direction perpendicular to the axial direction are damped by the side surface of the recess. Furthermore, vibrations and impacts in other directions are damped by both. Here, corrugated board is a high-strength material. Strong against vibration and shock. Therefore, it is possible to protect the object to be packed from vibration, shock, and the like.

Moreover, according to the corrugated cardboard core cushioning material of the present invention, since it is made of corrugated cardboard, it can be recycled as used paper after use. Therefore, it is also useful for saving timber resources. If it is buried in the soil, it will return to the soil after a certain period of time. In addition, it can be incinerated at low temperatures without producing harmful gases. Therefore, it helps to protect the environment.

 In order to further clarify the structure and operation of the present invention described above, a preferred embodiment of the present invention will be described below. [Example 1] Fig. 1 shows a perspective view of a corrugated cardboard core cushioning material 1 for corners of Example 1 of the present invention. The corrugated cardboard core cushioning material 1 for a corner is formed by winding a double-sided corrugated cardboard double. Double-faced corrugated board is preferable because of its high strength. The shape is a rectangular tube shape, and a cut 7 perpendicular to the axial direction is continuously formed at the center of the two side surfaces 3 and 5 that are connected to each other. Then, with the cut 7 as a boundary, the upper portion 9 is pressed in the direction of the other two side surfaces 11 and 13 and comes into contact with the other two side surfaces 11 and 13, forming an L-shaped recess 14.

According to the corrugated cardboard core cushioning material 1 for corners of the first embodiment, by fitting each corner of the article to be packaged between the concave portion 14 and the cylindrical lower portion 16, the article to be packaged can be successfully processed. Can be supported and buffered. That is, vibration and impact in the axial direction (X1 direction in FIG. 1) of the corrugated cardboard core cushioning material 1 are damped by the cylindrical lower portion 16. Further, vibrations and impacts in the direction perpendicular to the axial direction (Y1 and Y2 directions in FIG. 1) are damped by the surface of the recess 14. Furthermore, vibrations and impacts in other directions are damped by both. Here, since corrugated board is a material having high strength, it is resistant to vibration and shock during transportation. Therefore, the object to be packed can be protected from being damaged by vibration and impact during transportation, and the damage can be prevented. Moreover, since the corrugated cardboard core cushioning material 1 for corners is made of corrugated cardboard, it can be used after use. Can be recycled as waste paper. Therefore, it is also useful for resource saving of wood. If it is buried in the soil, it will return to the soil after a certain period of time. In addition, incineration can be done at low temperatures without harmful gases. Therefore, it helps protect the environment.

Next, a method of manufacturing the corrugated cardboard core cushioning material 1 for corners will be described. FIG. 2 shows a developed view before the assembly. First of all, a strip-shaped double-faced corrugated board 15 having a width equal to the height of the corrugated cardboard core cushioning material 1 for corners and twice the length of the circumference of the corrugated cardboard core cushioning material 1 for corners is used. prepare. Then, seven fold lines 17 are marked perpendicularly to the longitudinal direction and at substantially equal intervals. The folding line 17 divides the double-faced corrugated board 15 into eight small pieces 19, 21, 23, 25, 27, 29, 31, 33. The small pieces 25, 26 wound on the outer side and the small pieces 29, 31, 33 placed on the outer side are slightly divided as compared with the small pieces 19, 21, 23 wound on the inner side.

Secondly, continuous cuts 7a and 7b parallel to the longitudinal direction are respectively formed in the centers of the second and third small pieces 21, 23, 29 and 31 from the small pieces 19 and 33 at both ends thereof. Form. Thirdly, the adhesive 39 is applied to the small piece 33 at one end.

Fourth, as shown in FIG. 3, with the surface coated with the adhesive 39 as the inner side, the double-faced corrugated cardboard 15 is formed into a rectangular tubular shape from the small piece 19 at the other end along the bending line 17. Wrap it twice. Then, finally, the small piece 33 at one end is adhered to the small piece 25 with the adhesive 39, and the wound final end is fixed.

Then, a rectangular tubular body as shown in FIG. 4 is formed. Here, the cuts 7a and 7b overlap each other. Fifthly, in the two side surfaces 3a, 5a (corresponding to the small pieces 21, 23, 29, 31 above) on which the cuts 7a, 7b are formed, the upper side 36 of the cuts 7a, 7b is separated from the other two side surfaces 11a, A substantially L-shaped recess 14a is formed by pressing in the a3a direction (corresponding to the small pieces 19, 25, 27, 33) and bringing them into contact with each other.

Then, the corrugated cardboard core cushioning material 1 for corners shown in FIG. 1 is completed. As described above, the corrugated cardboard core cushioning material 1 for corners of the first embodiment can be manufactured by an extremely simple method such as cutting, winding, and pressing a corrugated ball.
