Description

  The present invention relates to a shock-absorbing packaging material disposed inside a packaging box for packaging an article to be packaged.

  Articles such as image forming apparatuses, household electric appliances, and functional members and electronic parts constituting them are usually packaged and shipped in a packaging box made of cardboard or the like. Many of the packaging boxes have a form in which an article to be packaged is completely accommodated in a cardboard box. In order to protect the package from impact during transportation, the package is often housed in a packaging box via a buffer packaging material.

  When a plurality of items to be packaged are accommodated in a single packaging box, or a space is provided between the packaging box and the packaged item, a buffer packaging material is disposed inside the packaging box. The This shock-absorbing wrapping material provides a buffering action so that a plurality of items to be packaged in the packaging box do not collide with each other, or the packaged item does not move greatly due to the impact of the packaging box and collide with the inner wall. It is. In this way, the cushioning packaging material protects the articles to be packaged contained in the packaging box from damage.

An example of the buffer packaging material as described above can be seen in Patent Document 1. The cardboard cushioning material (buffer packaging material) described in Patent Document 1 is formed by bending the outer edge of a single plate-like cardboard upward in four directions, thereby providing a bottom wall and four side walls. Is forming. A plurality of protrusions projecting outward by cutting and raising are provided at the respective folds of these wall portions.

  The cardboard cushioning material (buffer packaging material) described in Patent Document 1 surrounds the product by the bottom wall and four side walls, and further provides a protrusion extending downward and laterally to improve the cushioning performance. At the same time, in order to reduce the resistance generated at the tip of the protrusion when forming the protrusion, a through hole is provided at the tip to prevent breakage of the base of the protrusion while improving the efficiency of assembly work. Yes. However, this corrugated cardboard cushioning material has to discard the corrugated cardboard material at the location of the through hole, and there is a concern that resources will be wasted.

  Further, the corrugated board material at the location of the through hole needs to be removed manually or automatically using a mold. As a result, the number of man-hours increases, and in the case of manual work, labor costs are more than necessary. Furthermore, when removing a piece automatically using a mold, there is a risk that a mold different from the mold for forming the entire cushioning packaging material may have to be manufactured, which greatly increases the resources and costs involved. This is contrary to the resource saving and cost reduction that have been promoted recently.

  The present invention has been made in view of the above points, and in the cushioning packaging material disposed inside the packaging box, a resource-saving and cost-saving cushioning packaging material with sufficiently enhanced cushioning performance is provided. The purpose is to provide.

It was decided to have a notch extending to

  Moreover, in the buffer packaging material having the above-described configuration, the cut is formed with a length corresponding to at least the thickness of the plate-like member.

  Further, in the cushioning packaging material having the above-described configuration, the protrusion is configured to have a substantially rectangular shape with one side being an extension line of the fold between the two wall portions, and is parallel to the other two sides adjacent to the one side. The notches are formed so as to extend continuously.

  Moreover, in the buffer packaging material having the above-described configuration, the cuts are formed at a plurality of locations, and the plate-like member at a location between the plurality of cuts is locally compressed in the thickness direction.

  According to the configuration of the present invention, the cushion packaging material is flush with the surface of one of the two wall portions as it is folded between two adjacent wall portions of the plate-like member. And a notch extending in the direction away from the crease between the two wall portions at the location of the other wall portion opposite to the end portion of the protrusion, and having a protrusion protruding outward from the other wall portion. Therefore, it is possible to reduce resistance generated at the end of the protrusion when the protrusion is formed by cutting and raising without providing a through hole at a position facing the end of the protrusion. Thereby, it is possible to easily form a protrusion capable of improving the buffering performance, and to prevent a cut end from occurring at the end portion of the protrusion. Therefore, it is not necessary to generate a manual work or to separately manufacture a mold for removing the cut ends, and it is possible to prevent waste of the material applied to the cushioning packaging material. In this way, it is possible to obtain a shock-absorbing packaging material in which resource saving and cost reduction are achieved and the shock-absorbing performance is sufficiently enhanced.

  Further, since the cut is formed with a length corresponding to at least the thickness of the plate-like member, the effect of reducing the resistance generated at the end of the protrusion when forming the protrusion is sufficiently enhanced. be able to. As a result, it is possible to reliably realize the efficiency of the assembly operation of the cushioning packaging material and the prevention of the breakage of the root portion of the protrusion. Therefore, the buffer performance can be further improved while saving resources and reducing the cost of the buffer packaging material.

  In addition, the protrusion is configured in a shape that forms a substantially rectangular shape with an extension line of the fold between the two wall portions as one side, and extends continuously in parallel with the other two sides adjacent to the one side. Since the notches are formed, the resistance generated at the ends of the protrusions when the protrusions are cut and raised can be further reduced, and the protrusions can be formed more easily. Thereby, it can prevent effectively that a protrusion breaks in the base part, and it is possible to further improve the buffer performance of a buffer packaging material.

  Moreover, since the said notch is formed in several places and the said plate-shaped member in the place between these several notches was compressed locally in the thickness direction, a protrusion is formed like the above. At this time, the resistance generated at the end of the protrusion can be further reduced, and it becomes easier to form the protrusion. Thereby, it can prevent effectively that a protrusion breaks in the base part, and it is possible to further improve the buffer performance of a buffer packaging material.
