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 cushioning fixing material for packaging (buffer packaging material) described in Patent Document 1 is a portion where the outer edge portion is once bent so that the corrugated board is doubled and further overlapped with each other One of the upper layers is folded upward so as to have a box-shaped cross section, thereby forming an accommodation portion, a buffer portion, a side wall, and the like of an object to be packaged.

  The cushioning fixing material for packaging (buffering packaging material) described in Patent Document 1 is a buffering fixing part for a package by temporarily bending the outer edge of one cardboard board so that the cardboard boards are doubled. Assembling is extremely easy. However, since the portion of the fold folded to make it double is going to be restored by the elasticity of the cardboard, it is not easy to maintain the shape of the cushioning packaging material. Thus, the packaging buffer fixing material (buffer packaging material) described in Patent Document 1 employs a method of bonding and fixing a part of the double corrugated board. Therefore, an adhesive member such as an adhesive or a double-sided tape is required, and the assembly process increases. As a result, the resources and costs for the packaging material may be significantly increased, which is contrary to the recent resource saving and cost reduction.

  In addition, when a double place is provided locally using a plate-like member such as corrugated cardboard, the fold of the double place tries to return to the original while the other place is bent, so that the assemblability is poor. There is also a problem. Therefore, it is necessary to construct the buffer packaging material in such a way that the assembling property, the resource saving, and the cost reduction are achieved as much as possible while obtaining the merit in the buffer performance by doubling the plate-like member such as cardboard. There is.

  The present invention has been made in view of the above points, and in the cushioning packaging material disposed inside the packaging box, the buffering performance is sufficiently maintained, and the assembling property, resource saving, and cost reduction are reduced. The object is to provide the intended cushioning packaging.

  In order to solve the above-mentioned problems, the present invention provides a double substantially vertical shape formed by folding downward two opposite sides of a rectangular plate-shaped member and further folding upward on the outside thereof in a cushioning packaging material. A side wall having leg portions and a joining structure configured to utilize the side wall and / or a plate-like member in the vicinity of the side wall to prevent separation of the stacked plate-like members on the side wall are provided.

  In the shock-absorbing packaging material having the above-described configuration, the joining structure extends toward the side wall by being cut and raised from a substantially central portion of the rectangular plate-like member in accordance with the downward bending in the side wall formation. And an engagement hole provided on the side wall and holding the insertion piece.

  Further, in the shock-absorbing packaging material having the above-described configuration, the joining structure is provided at a position corresponding to each other of the overlapped plate-like members on the side wall, and the other is bent by bending one toward the other. A pair of cut-and-raised pieces that engage with the resulting hole or groove was provided.

  According to the configuration of the present invention, the shock-absorbing wrapping material has double substantially vertical legs formed by folding downward the two opposite sides of the rectangular plate-shaped member and further bending upward on the outside thereof. Since it is provided with a bonding structure that prevents separation of each of the stacked plate-like members on the side wall, which is configured using the side wall and / or a plate-like member in the vicinity of the side wall. Without using an adhesive member such as a double-sided tape, the double plate-like member can be prevented from being restored due to its elasticity, and the double state can be maintained. Thereby, when using a plate-shaped member and forming a double location with high buffering performance, it is easy to assemble and it is possible to significantly suppress resources and costs on the plate-shaped member. Therefore, it is possible to obtain a shock-absorbing packaging material in which assemblability is improved, resources are saved, and costs are reduced while sufficiently retaining shock-absorbing performance.

  In addition, the joint structure is formed by extending from the substantially central portion of the rectangular plate member and extending toward the side wall in accordance with the downward bending in the side wall formation, Since it is provided with the engagement hole provided on the side wall and holding the insertion piece, it is not necessary to configure by inserting another member. Thereby, it is possible to form a double location having a high cushioning performance with respect to an object to be packaged by using as little plate-like member as possible. Moreover, since no separate member is used, the assemblability is good. Accordingly, it is possible to further improve the assembling property, the resource saving, and the cost reduction while sufficiently considering the effect of protecting the packaged object.

  Further, the joining structure is provided at a position corresponding to each other of each of the stacked plate-like members on the side wall, and is engaged with a hole or a groove formed by bending one side toward the other side. In addition, since the pair of cut and raised pieces are provided, it is not necessary to insert another member or the like as in the case of the structure of the joining structure. Thereby, it is possible to form a double location having a high cushioning performance with respect to an object to be packaged by using as little plate-like member as possible. Moreover, since no separate member is used, the assemblability is good. Accordingly, it is possible to further improve the assembling property, the resource saving, and the cost reduction while sufficiently considering the effect of protecting the packaged object.
