Description

  The present invention relates to a packaging material and a packaging material for an article, and more particularly, to a packaging material and a packaging material suitable for storing an attached document attached together with the article when the article is packaged.

  When an article such as an electric device is packed in a packing material such as a cardboard box, an attached document such as an installation instruction and an instruction manual related to the article is usually packed together with the article. In many cases, the attached document is stored in a gap inside the article, or in a plastic bag and attached to the article with a tape or the like. However, such a conventional attachment method has the following problems.

  When an attached document is stored in a gap inside the article, the attached document cannot be taken out before unpacking. Further, when the article has a shape that does not have an opening, it is not possible to even store an attached document in an internal gap.

  Even when the attached document is attached to the article with tape, the attached document cannot be taken out before unpacking. This is because, for example, the article is covered and packaged by a product cover made of polyethylene, for example, and the attached document is inside the product cover. Moreover, since a tape sticking process necessarily occurs, a time cost required for the process and a monetary cost required for materials such as a tape are generated.

  In the attached document, there is also a document that is used before handing over the article to the end user in the distribution process of the article, such as a warranty that requires the purchase date and the name of the store to be filled in at the store. To do. In order to take out such a document, it was necessary to unpack it, which caused inconvenience.

As a solution to such a problem, for example, a packaging device described in Patent Documents 1 and 2 is known. According to these packing apparatuses, the attached document can be easily pulled out of the outer box, and can be easily stored in the outer box again after being pulled out. Therefore, it is not necessary to unpack the package in order to take out a document such as a guarantee used before delivering the article to the end user. Furthermore, since the tape fixing step is not required, the time cost required for the step and the monetary cost required for materials such as tape can be reduced.
