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 corrugated cardboard cushioning material (buffer packaging material) described in Patent Document 1 is obtained by bending two opposing sides of the outer edge portion inward at a plurality of locations with respect to one plate-shaped cardboard. , Standing up upward with respect to the bottom surface, forming two opposing buffer boxes.

  The buffer box of the cardboard cushioning material (buffer packaging material) described in Patent Document 1 is fixed by inserting the insertion piece formed on the bottom surface part into the corresponding insertion part, and a buffering action is expected. It is formed as a cylindrical box having a rectangular cross section. However, even if the buffer box is formed by bending at multiple locations, the cardboard material has the property of returning to its original plate shape due to its elasticity. There may be a gap between the bent portion of the buffer box. In addition, this may cause the two buffer boxes to be distorted and tilted so as to fall outside each other. Therefore, there is a concern that the formation of the buffer box lacks stability and the working efficiency of the packaging is reduced.
