Abstract

PURPOSE:To reduce the size of a packing container by minizing an inner packing having a shock absorbing effect incineration calory by using material which generated a small amount of incineration heat as inner packing. CONSTITUTION:A cylindrical film sheet 1 and a thick plate 2 which is inserted into the film sheet 1 and can be bent easily constitute an inner packing 3 for packing an anticle. In this instance, the width of the thick plate 2 is larger than the maximum width of the cylindrical film sheet 1. Ar article is sandwiched from both sides by the inner packing 3 and housed into an outer packing. A space is formed between the inside film sheet 1 of the inner packing 3 and the thick plate 2 for absorbing shock.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to packaging interior materials and packaging containers.

0002

[Prior Art] In order to prevent damage caused by external shocks, the packaged items such as electrical equipment and housing equipment are made of foamed resin between the packaging material and the packaged item, which is a packaging container such as cardboard or a wooden frame. This method uses an interior material (buffer material), but this interior material requires a considerably large volume to be placed inside the packaging container, making the packaging container larger and reducing transportation efficiency. In order to incinerate the used packaging containers, the interior material has a large volume and generates a large amount of heat during incineration, which is a factor that damages the incinerator.

0003

[Problem to be Solved by the Invention] In the above-mentioned conventional example, when the interior material is formed using foamed synthetic resin, the volume of the interior material occupied in the packaging container cannot be reduced in view of the buffering capacity. There is a problem. The present invention was invented in view of the problems of the above-mentioned conventional examples, and
The purpose of this is to reduce the amount of heat generated by incineration by using interior materials that have a cushioning effect and a low calorific value when incinerated. and to provide packaging containers.

0004

[Means for Solving the Problems] In order to achieve the above object, the packaging interior material of the present invention has a cylindrical film sheet 1, a width larger than the maximum width of the film sheet 1, and a film It is characterized by consisting of a bendable thick plate body 2 inserted into a sheet 1.

The packaging container of the present invention also includes a cylindrical film sheet 1 and a bendable thick plate body 2 having a width larger than the maximum width of the film sheet 1 and inserted into the film sheet 1. The interior material 3 is composed of two sheets of the interior material 3, and the product 4 to be packaged is sandwiched between the two interior materials 3 from above and below or from both sides, and then stored in the exterior material 5. Here, the two interior materials 3 that sandwich the packaged product 4 from both sides are formed to have a substantially U-shaped cross section, and a space 6 is formed between the inner film sheet 1 of the interior material 3 and the thick plate body 2. It is preferable to allow the formation of

[0006]

[Operation] Thus, the thick plate body 2 placed in the cylindrical film sheet 1 is bent at a location closer to the inside than both side edges thereof. As a result, a space 6 is formed between the folded inner film-sheet 1 and the thick plate 2, and depending on the size of the gap between the spaces 6, a cushioning effect suitable for the packaged product 4 can be obtained. It turns out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail based on embodiments shown in the accompanying drawings. In FIGS. 2 and 3, 4 is a packaged item such as electrical equipment or housing equipment. 3 is an interior material, and 5 is an exterior material consisting of an exterior box. The interior material 3 consists of a cylindrical film sheet 1 and a bendable thick plate body 2 placed inside the film sheet 1. The film sheet 1 used in the present invention is made of synthetic resin films such as vinyl chloride and polyethylene, as well as cotton, nonwoven fabric, paper, synthetic resin fiber materials, and the like. This film sheet 1 may be formed by cutting a cylindrical film sheet material to an appropriate width (for example, width A in FIG. 1), or may be formed by joining both ends of the film sheet 1 to an appropriate width A. It may be formed into a shape. Further, the thick plate body 2 is made of cardboard, cardboard, synthetic resin board, plywood, wooden board, or the like. If the thick plate body 2 is a rigid body, a bending line (key line) 7 may be provided as shown in FIG.
It can be bent freely by other mechanical connection means.

[0008] Here, the width B' of the thick plate body 2 is formed to be equal to or larger than the maximum width B of the cylindrical film sheet 1 when it is stretched. For example, when the width B' of the thick plate body 2 is 600 mm, the maximum width B when the film sheet 1 is stretched is 540 mm. As a result, when the thick plate body 2 is bent into a U-shape, a space 6 is formed between the film sheet 1 and the thick plate body 2 on the folded side, and due to the existence of this space 6 of width X, Packaged item 1
It also functions as a buffer against

[0009] The interior material 3 having the above-mentioned structure is used as the packaged product 4.
are stored in the exterior material 5 in a state where they are sandwiched from above and below. In this case, depending on the packaged item 4, it may be pinched from both the right and left sides, and the key is to pinch the packaged item 4 from the direction that requires cushioning. Moreover, the two interior materials 3, 3 facing each other may be sandwiched vertically so as to cross each other, or may be sandwiched without crossing each other, and in either case, they are protected by being housed in the exterior material 5.

[0010] By the way, there are cases where it is necessary to cushion and protect only one surface of the packaged product 4. In such a case, one interior material 3 is used and the other surface of the packaged product 4 is directly protected. It is protected by an exterior material 5, or a thick plate of an appropriate size and material is interposed.

[0011]

Effects of the Invention As described above, the present invention comprises a cylindrical film sheet and a bendable thick plate body having a width larger than the maximum width of the film sheet and inserted into the film sheet. Since the interior material is composed of , the cylindrical film sheet containing the thick plate functions as a cushioning material, and there is no need to use a large-volume cushioning material such as foamed synthetic resin as in the past. The volume of the interior material can be reduced, and as a result, packaging containers using the interior material as a cushioning material can be made smaller, increasing transportation efficiency and reducing the amount of heat generated when the packaging containers are incinerated. This can prevent damage to the incinerator and reduce the amount of pollution generated.

[0012] Furthermore, the interior material is constituted by a cylindrical film sheet and a bendable thick plate having a width larger than the maximum width of the film sheet and inserted into the film sheet, and the interior material is composed of two interior materials. Since this is a packaging container in which the packaged item is sandwiched between the top and bottom or left and right sides and then stored in the exterior material, the cylindrical film sheet functions as a cushioning material.
There is no need to use large-volume cushioning materials such as foamed synthetic resin as in the past, and packaging containers can be made smaller, increasing transportation efficiency and reducing the amount of heat generated when packaging containers are incinerated. It is possible to simplify the packaging work and increase the work efficiency, and also to sandwich the packaged items from both sides. By forming a space between the thick plate body and the thick plate body, the cushioning effect can be changed according to the packaging container, and it can be easily applied to packaged products of various weights and sizes.
