Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging method for packaging an object to be packaged having an unfaced surface shape and a protruding structure, and a packaging device for an object to be packaged having an unfaced surface shape and a protruding structure. is there.

[0002]

2. Description of the Related Art A very general method of packaging is to put a packaged object in a rectangular outer box made of corrugated cardboard with a gap filled with a cushioning material. Styrofoam, which is lightweight and resistant to compression, has been widely used as a cushioning material in the past. However, since styrofoam is bulky and requires a large storage space, and there is a problem with its disposal, packaging technology is being advanced in a direction where it is not used as much as possible. For example, Japanese Utility Model Publication No. 62-42929 discloses a packaging device using a cushioning material formed of corrugated cardboard, in which styrofoam is bonded only at essential points.

Further, for example, as shown in Japanese Utility Model Publication No. 62-44901, the outer box is composed of two C type boxes (JI.
Sz-1507 code number 0300) and two U-shaped cushioning materials formed by folding corrugated cardboard paper between them to form a C-shaped box and a C-shaped box. There is also a way to wrap it in the form of wrapping it with cushioning material. In this way, by using an outer box that is not completed as a box by itself,
The extra volume can be eliminated and the volume of the packaging form can be reduced with less material. Also in the packaging device shown in this publication, a cushioning material made of Styrofoam is packed only between the corners of the article to be packaged and each C-type box as in the former case.

[0004]

The conventional packaging device as described above is widely used for packaging electrical products and the like.
Both of them are still using styrofoam, although they are minimal, and their disposal is still problematic. In particular, corrugated cardboard with Styrofoam bonded to it is difficult to separate the corrugated cardboard from the Styrofoam, and is poor in disposal. However, when the object to be packaged is a hexahedron formed by facing, or an outer shape similar to this, the packaging volume tends to decrease from the beginning, and it is not so easy to devise ways to reduce the amount of Styrofoam. It's not difficult.

However, it is not so easy in the case of a packaged product having a non-faced surface shape and an external shape including a protruding structure in a part thereof. That is, between the outer box that is basically composed of a face and the surface shape that is composed of a non-face,
A gap is formed due to the projecting structure, and it is necessary to fill this gap in order to put the packaged object in a buffered state. To fill such a relatively large gap, it is also easy to use styrofoam of the molded product. Regardless of this method that deviates from the current state of packaging technology, although it is possible to form a cushioning material that does not use Styrofoam if you form a cushioning material in a shape corresponding to the gap with corrugated paper and fill the gap with these, As it is, the packaging volume cannot be reduced, and it takes time to form the cushioning material and the packaging material is bulky, which is not costly.

The present invention has been made in order to solve the above-mentioned conventional problems, and its problem is to have an outer surface having a non-facetted surface shape and partially including a protruding structure. Packing materials with a small packing volume and a small packing material,
The purpose of the present invention is to obtain a packaging method capable of packaging without using Styrofoam, and a packaging material that has a non-facetted surface shape and has an external shape that partially includes a protruding structure in a small packaging volume. Therefore, it is to obtain a packaging device that can perform packaging without using styrofoam, and to achieve improvement of the cushioning function and the protection function of the packaging device.
