[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for packaging products used when packaging products by placing them in a packaging box.

[0002]

2. Description of the Related Art As shown in FIG. 8, a cushioning material of this type is fitted in a corner portion or an end portion of a product A, and its outer surface is brought into contact with an inner surface of the packaging box to thereby The product positions the product and also functions as a buffer against external shocks.

Therefore, as a material for forming the cushioning material 60,
Styrofoam and the like having appropriate shape retention and elasticity are generally used.

However, the cushioning material formed of expanded polystyrene has a problem in disposal after use, which causes pollution.

Therefore, an object of this invention is to have a cushioning function equivalent to that of a conventional cushioning material formed of styrofoam,
Moreover, it is to provide a cushioning material for packaging that does not cause pollution even when it is discarded after use.

[0006]

To solve the above problems BRIEF SUMMARY OF THE INVENTION This invention is to surround the outer circumference of the end portion of the product in a state of being fitted into the packing box, the large barrel slightly from the commodity, the upper plate,
Formed by the bottom plate and both side plates, the outer side of the body is
Extend the left and right sides of both side plates, the top plate and the bottom plate, and connect the support legs to each other, and make a crease on the outer side of the center of the top plate and the bottom plate.
Folded at right angles through the wires and facing each other
A series of support plates to be twisted together, and the center of the upper and lower plates
The cardboard cushioning material made of cardboard or the like is provided on the inner side of which a cushioning plate that is folded back to the inner surface of the body is continuously provided.

[0007]

In the cushioning material configured as described above, the end portion of the product is fitted inside the cushioning material and the end surface of the product is brought into contact with the support plate. When the product is placed in the packaging box in this state, the cushioning material contacts the inner surface of the packaging box and the product is held in a state of floating in the packaging box.

In this state, the outer periphery of the end of the product has a buffer plate bent between itself and the packaging box, and the end plate of the product has a support plate and a space, so that an external impact is directly applied. It does not reach the end of the product.

Particularly, the support plate is a central portion of the upper plate and the lower plate.
Is bent at a right angle to the outer side of the
These are arranged in series so that they face each other and are stacked.
Therefore, it is easy to structurally deform with respect to the body,
The buffering property from the part is improved. Also, cardboard and other thick paper
Since it is manufactured, it can be disposed of after use, like the packaging box.

EXAMPLES Examples will be described below with reference to the drawings. The packaging cushioning material shown in FIGS. 1 and 2 is assembled from a cardboard blank such as a corrugated board shown in FIG.

This blank includes support legs 11a, 12a,
A side plate 13, a top plate 11, and a side plate 1 in which 13a are continuously provided.
3, the bottom plate 12 and the seam allowance 14 are fold lines 41, 42,
The support plates 21 and 22 are connected to one end of the upper surface plate 11 and the lower surface plate 12 via fold lines 45 and 46, respectively.

Further, connecting plates 11b, 12b, 13b are connected to the other ends of the upper plate 11, the lower plate 12 and the side plate 13 via fold lines 47, 48, 49, respectively. Fold lines 51, 52, 5 on 12b, 13b
Buffer plates 31, 32, and 33 are connected in series via the line 3.

Cutouts 31b and 32b that form the protrusions 31a and 32a are provided at the central portions of the cushioning plates 31 and 32, and the cushioning plates 31 and 32 are sandwiched between the cutouts 31b and 32b. Fold lines 54 and 5 that fold in half
5 are provided.

Further, a folding piece 21a is continuously provided on both side edges of one of the support plates 21 through a fold line 56, and the projecting piece is provided at the central portion along the fold line 45 and an end edge facing the fold line 45. Slit 21b with which 31a and 32a engage
And the notch 21c is formed.

In the blank constructed as described above, first, the seam allowance 14 is applied to the one side plate 13 and the supporting foot 13a.
To form a rectangular tubular body, and as shown in FIG.
After the folded piece 21a is folded back to the inner surface side of the support plate 21, the folded piece 21a is folded into the body portion, and then the other support plate 22 is folded on it.

Then, as shown in FIG. 5, the folding piece 2
Raise 1a and put it along the side plate 13, and insert the folded piece 2
The buffer plate 33 is folded on 1a.

Finally, the other cushion plates 31 and 32 are folded in two and folded over the inner surfaces of the upper plate 11 and the lower plate 12, and the respective projections 31a and 32a are slit 21b.
By engaging with the notch 21c, the cushioning material for packaging shown in FIG. 1 is completed.

As shown in FIG. 1, the two support plates 21 and 22 are held by tape fixing or sticking with an adhesive.

When the product A is packed in the packaging box B using this cushioning material, as shown in FIG. 1, the cushioning material is fitted to both ends of the product A so that the end surfaces of the product A contact the support plate 21. , Put it in the packaging box B as it is.

In the packed state, as shown in FIGS. 2 (a) and 2 (b), the outer surface of the cushioning material abuts the inner surface of the packaging box B and the product A is held in a floating state.

Further, the outer periphery of the end portion, which is the support portion of the product A, is
Two-fold buffer plates 31, 32, or buffer plates 33 and folding pieces 21a are provided between the packaging box B and the body part in a three-layered manner together with the body portion, and at the end surface of the product A, a two-layered support is provided via the space C. Since the plates 21 and 22 are interposed, the impact from the outside is not directly transmitted to the product A.

6 and 7 show another embodiment. This cushioning material for packaging is replaced with the support plate 21 instead of the support plate 21.
2 is provided with a slit 22b and a cutout portion 22c.

As shown in FIG. 6, this cushioning material is obtained by folding the supporting plate 22 on the inner surface of the lower plate 12 and then inserting the folding piece 2
The support plate 21 in which 1a is folded is bent into the body part, and
As shown in FIG.
Then, the support plate 22 is folded on the support plate 21, and the rest is assembled in the same manner as in the above embodiment.

With such a structure, the folding piece 21
Since the side edge of a contacts the lower surface plate 12 to prevent the support plate 21 from spreading to the outside, there is an advantage that the shape can be maintained without the tape fixing as in the above-described embodiment.

[0025]

[Effect] With the above-mentioned structure, when a product is packed using the cushioning material of the present invention, the outer periphery of the end of the product is impacted by the cushioning plate, and the end face of the product is impacted from the outside by the support plate and the air layer. It will be softened and will exert the same cushioning function as that of conventional styrofoam products.

Further, after use, since it can be disposed of by incineration or the like together with the packaging box made of corrugated cardboard, it does not cause pollution.
