BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior material for a packaging container used as a buffer for packaged items.

0002

[Prior Art] Conventionally, in order to prevent damage caused by external shocks, foamed synthetic resin has been used for packaging products such as electrical equipment and housing equipment between the exterior material of the packaging container, such as cardboard or wooden frames, and the packaged products. However, this cushioning material must have a considerably large volume in the packaging container, making the packaging container larger and reducing transport efficiency. Moreover, when incinerating packaging containers that are no longer needed, interior materials with large volumes generate a large amount of heat during incineration, which is a factor that damages the incinerator.

For this reason, if foamed synthetic resin is used as the interior material, which is a cushioning material, the volume occupied by the interior material in the packaging container cannot be reduced in view of the cushioning capacity of the foamed synthetic resin. Therefore, it is necessary to improve the interior material, which is a cushioning material, to make the packaging container smaller, and to reduce the amount of heat generated by incineration by using a material with a small calorific value when incinerated as the interior material. It is considered.

[Problems to be Solved by the Invention] One possible solution is a combination of a film sheet and a small-sized thick plate for the interior material of a packaging container. This product is constructed by attaching thick plates to both ends of a film sheet.
If the thick plates of film sheets are simply connected to each other, careful adhesion is required to ensure strength. Further, in the case where the connection strength is compensated for by folding or wrapping the film sheet around a thick plate, there is a problem in that the work is time-consuming.

The present invention aims to solve the above-mentioned problems, and provides an interior material for a packaging container that is easy to connect a film sheet and a thick plate body, and is used as a buffer to withstand the weight of the packaged product. is to provide.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the interior material for a packaging container of the present invention is constructed by connecting two thick plate bodies 1 with a film sheet 2.
This is characterized in that storage portions 4 are provided at both ends of the film sheet 2, and the two thick plate bodies 1 are individually placed in the storage portions 4.

[0007] Here, the storage section 4 for the film sheet 2 is
is a pocket 5, and it is preferable that the two thick plates 1 be inserted into the pockets 5 separately. Further, the storage section 4 for the film sheet 2 is configured such that both ends of the film sheet 2 are folded back and the thick plate body 1 is inserted therein, and the storage section 4 is sealed with an adhesive tape 6. is also preferable.

[0008]

[Function] Therefore, the interior material 3 of the packaging container formed by connecting the two thick plate bodies 1 with the film sheet 2 is the same as the thick plate bodies 1.
are stood in parallel and formed into a substantially U-shape by the film sheet 2 and the two thick plates 1. When the packaged product 7 is placed on the film sheet 2 between the two thick plate bodies 1 in this state, the weight of the packaged product 7 added to the film sheet 2 is supported by the thick plate body 1 through the storage section. Ru.

Storage portions 4 are provided at both ends of the film sheet 2, and the two thick plate bodies 1 are placed in the storage portions 4 separately.
Since the interior material 3 of the packaging container is configured such that the film sheet 2 is placed in the film sheet 2, the thick plate body 1 can be easily connected to both ends of the film sheet 2. In addition, the storage section 4 of the film sheet 2
is a pocket 5, and by configuring the two thick plate bodies 1 to be inserted into the pockets 5 separately, by simply inserting the thick plate body 1 into the pocket 5, the thick plates can be attached to both ends of the film sheet 2. Body 1 can be connected. In addition, when the packaged product 7 is placed on the film sheet 2 between both thick plate bodies 1, the weight of the packaged product 7 is such that the pocket 5 covering the thick plate body 1 engages with the thick plate body 1 and prevents the film sheet 2 from coming off. I'm here.

[0010] Furthermore, in the case where the storage section 4 for the film sheet 2 is one in which the thick plate body 1 is inserted by folding back both ends of the film sheet 2, and the storage section 4 is sealed with an adhesive tape 6. The folded portion is covered with a thick plate 1, and the load applied to the film sheet 2 is supported by the thick plate 1 as described above. Film sheet 2 like this
When the packaged product 7 is placed on the packaged product 7 or when the interior material 3 is placed on the packaged product 7, the thick plate body 1 is placed on the film sheet 2.
It is connected to the storage section 4 so that it cannot be easily detached.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail based on embodiments shown in the accompanying drawings. FIG. 1 shows an embodiment of the invention. In FIG. 1, 7 is a packaged item such as electrical equipment or housing equipment. 3 is an interior material according to the present invention. This interior material 3 is constructed by connecting two thick plate bodies 1 with a film sheet 2. The thick plate 1 is approximately the same height as the packaged product 7 to approximately 1/2H (here, H is the height of the packaged product 7), and the width of the thick plate 1 is equal to one side of the packaged product 7. The length is approximately equal to the width B. The thick plate body 1 is made of cardboard, plywood, wooden board, or the like. The film sheet 2 has storage parts 5 at both ends into which the thick plate 1 can be inserted from the longitudinal direction of the film sheet 2 or from the cross direction thereof, and is made of a synthetic resin film such as vinyl chloride or polyethylene, or cotton or paper. , synthetic resin materials, etc. are used. Further, the film sheet 2 may contain reinforcing threads made of metal, glass fiber, cotton, or synthetic resin, or may be a woven fabric or a non-woven fabric. This film sheet 2 connects two thick plates 1 to form one interior material 3.
This is the result. The top and bottom or left and right sides of the packaged product 7 may be sandwiched using two such interior materials 3, but if the width C of the other packaged product 7 is longer or shorter than the width B, Another interior material 3 having approximately the same width as the other side width C of the product 7 is used.

[0012] In the connection between the film sheet 2 and the thick plate body 1, the position is slightly shifted from one end edge of the two opposing thick plate bodies 1 to the other edge side (at a position indicated by X in FIG. 1). The spanning part of the film sheet 2 is located at the position shown in FIG. A void 8 is formed in the film sheet 2, and when it is packaged in an exterior material 9 as described later, this void 8 exists between the exterior material 9 and the spanning portion 2a of the film sheet 2, and cushioning is provided. It looks like this.

Both interior materials 3 sandwich the packaged product 7 with one interior material 3 facing upward and the other interior material 3 facing downward, either in the same direction or in a crosswise manner. The thick plate bodies 1 of No. 3 are placed on the corresponding sides of the packaged product 1 and housed in an exterior material 9 made of cardboard, a wooden frame, or the like. Therefore, the thick plate body 1 of the interior material 3 surrounds the four sides of the product 7 to be packaged, and the film sheet 2 is stored in the exterior material 9 in a state that covers the top and bottom surfaces of the product 7 to be packaged. In this state, the spanning portion 2a of the film sheet 2 of the lower interior material 3 is floating above the bottom surface of the exterior material 9, so the packaged product 7 is in a suspended state, and the weight of the packaged product 7 is 4 rests on the portion that engages with the thick plate body 1, thereby preventing the thick plate body 1 from coming off from the storage portion 4 and ensuring that the thick plate body 1 is held securely.

By the way, as shown in FIG. 2, the storage section 4 for the film sheet 2 is formed by folding back both ends of the film sheet 2 and sealing both longitudinal edges by heat welding to form a pocket 5. (The thermally welded portion is indicated by the reference numeral 10 in the figure.), and this pocket 5 can be used as the storage portion 4. In this case, both thick plate bodies 1 can be attached to both ends of the film sheet 2 by simply inserting the thick plate body 1 into the pocket 5 which is the storage part 4 as shown in FIG. 3, and the two thick plate bodies 1 can be connected to each other. .

Further, FIG. 4 shows a state in which both ends of the film sheet 2 are folded back with the thick plate 1 inserted therein, and adhesive tape 6 is applied to seal the film sheet. In this case, the thick plate body 1 will not come off even if the interior material 3 is turned upside down, and the length of the film sheet 2 can be easily changed by simply changing the folding position. Since it is tape 6, it can be reused.

[0016]

Effects of the Invention As described above, in the interior material of a packaging container formed by connecting two thick plates with a film sheet, storage portions are provided at both ends of the film sheet. Since the two thick plate bodies are placed separately in the storage part and constitute the interior material of the packaging container, the film sheet and the thick plate body can be easily separated by placing the thick plate body in the storage part. can be connected, making it easy to manufacture as an interior material. Also, since the thick plate body is stored and held in the storage section, it will not come off even when the weight of the packaged items is added, and the It is possible to obtain an interior material that does not come off unnecessarily during handling of the product.

[0017] In addition to the above-mentioned effect, when the film sheet storage section is a pocket and the two thick plates are inserted into the pockets separately, the thick plates can be inserted into the pockets. This allows the thick plate body to be easily connected to both ends of the film sheet with just one step. Furthermore,
In cases where the storage section for the film sheet has both ends of the film sheet folded back and a thick plate inserted therein, and the storage section is sealed with adhesive tape, the folded section is covered with the thick plate. Similarly to the above, the thick plate body can reliably support the load applied to the film sheet.
