Abstract

PROBLEM TO BE SOLVED: To provide a shock absorbing material for packing capable of adapting it for a heavy product. SOLUTION: A shock absorbing material for packing is constructed such that pressure receiving plates 2 are raised from both edges of a bottom plate, end plates 3 connected to the upper edges of the receiving plates are suspended down outside the pressure receiving plates 2, both sides of the pressure receiving plates 2 are provided with side abutting plates 4 cut and raised from the bottom plate 1, upper edges of the side attendant plates 4 and the end plates 3 are connected by top pieces 5, the lower ends of the end plates 3 are extended downwardly from the bottom plate 1 and the extremities of the tongue pieces 6 projected from the bottom plate 1 are butted against the end plates 3 between the pressure receiving plates 2 and the side attendant plates 4. The pressure receiving plates 2 and the end plates 3 are placed adjacent to each other and the pressure receiving plates 2 are inclined in respect to the bottom plate 1. When the product is mounted on the bottom plate 1 so as to bridge over both pressure receiving plates 2, 2, a tension force may act on the bottom plate 1 from both pressure receiving plates 2, 2 and then the product is resiliently supported by the bottom plate 1 and both pressure receiving plates 2, 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for a package that is housed in an outer box together with an article to be packed, holds the article, and protects the article from vibration and impact.

[0002]

2. Description of the Related Art Conventionally, a cushioning material N as shown in FIG. 4 has been used. This cushioning material N makes the pressure receiving plate 51 stand upright from both side edges of the bottom plate 50, a top plate 52 is continuously connected to the upper end edge outward, and the end plate 53 hangs down from the outer end thereof. A side contact plate 54 cut and raised from the bottom plate 50 is provided at the lower end of the pressure receiving plate 51. The upper end edge of the side contact plate 54 and the end plate 53 are connected by a top piece 52a projecting inward from the top plate 52. Is cut out to provide a projecting piece 55, the projecting piece 55 and the lower end of the end plate 53 are extended below the bottom plate 50, and the tongue piece 56 projecting from the bottom plate 50 between the pressure receiving plate 51 and the side contact plate 54 is formed. The distal end comes into contact with the end plate 53.

[0005] As shown in FIG. 5, this cushioning material N is housed in the bottom of an outer box B, and a commodity G (a rice cooker in the drawing) is placed on a bottom plate 50. 51, the top piece 52a, and the side contact plate 54, so that the movement of the commodity G in the outer box B is prevented.

In this packed state, a buffer space is secured below and on both sides of the product G, so that the product G is protected from vibration and impact.

[0005]

However, in the cushioning material as described above, since the load of the product G is received only by the bottom plate 50, when the product G is heavy, the bottom plate 50 may sink,
In some cases, the pressure receiving plate 51 was torn from both side edges to the top plate 52 and the bottom plate 50.

In addition, since the top plate 52 is interposed between the pressure receiving plate 51 and the end plate 53, there is a problem that it takes time to bend the ridge line during assembly.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cushioning material for packing which can handle heavy objects and is easy to assemble.

[0008]

In order to solve the above problems, the present invention raises a pressure receiving plate from both side edges of a bottom plate,
The end plate connected to the upper edge is hung down outside the pressure receiving plate, and a side contact plate cut and raised from the bottom plate is provided on both sides of the pressure receiving plate, and the upper end edges of the side contact plate and the end plate are connected by a top piece, In a packing cushioning material in which the lower end of the end plate is extended below the bottom plate and the tip of a tongue piece protruding from the bottom plate between the pressure receiving plate and the side contact plate is brought into contact with the end plate, the pressure receiving plate and the end plate are Adjacently, the pressure receiving plate was inclined with respect to the bottom plate.

In the packing using the cushioning material, when the article is placed on the bottom plate so as to be bridged between the two pressure receiving plates, tension acts on the bottom plate from the both pressure receiving plates, and the article is elastically moved by the bottom plate and the both pressure receiving plates. Because it is supported, even if the article is heavy, excessive load acts on the bottom plate and the bottom plate sinks,
There is no breakage from both sides of the pressure plate.

Further, since the pressure receiving plate and the end plate are adjacent to each other without the top plate interposed therebetween, the cushioning member is easy to assemble.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The cushioning material M according to the present invention is made of corrugated cardboard, and the steps thereof are oriented vertically when assembled.

In the blank of the cushioning material M shown in FIG.
A pressure receiving plate 2 and an end plate 3 are sequentially provided on both side edges of the bottom plate 1, and a side contact plate 4 and a top piece 5 are sequentially provided on both sides of the pressure receiving plate 2 by cutting the bottom plate 1 toward the end plate 3. Is provided. A tongue piece 6 is provided between the pressure receiving plate 2 and the side contact plate 4 so as to protrude from the bottom plate 1 toward the top piece 5. A protruding piece 7 formed by cutting the bottom plate 1 is provided at the base end of the pressure receiving plate 2. Is provided.

This cushioning material M is used for packing as shown in FIG. 3 in a state where the above-mentioned blank is assembled in the form shown in FIG. When assembling, the bottom plate 1 and the pressure receiving plate 2
Then, the side contact plate 4 is raised, and the end plate 3 is hung down.

In this assembled state, the protruding piece 7 and the lower end of the end plate 3 extend below the bottom plate 1, the tip of the tongue piece 6 abuts on the end plate 3, and the pressure receiving plate 2 is inclined with respect to the bottom plate 1. I do.

The cushioning material M can be easily assembled because the pressure receiving plate 2 and the end plate 3 are adjacent to each other without a top plate interposed therebetween. Usage is also reduced.

Then, as shown in FIG. 3, when the product G is placed on the bottom plate 1 so as to span the pressure receiving plates 2 and 2, tension is applied to the bottom plate 1 from the pressure receiving plates 2 and 2 and the product G Is the bottom plate 1
, And elastically supported by both pressure receiving plates 2 and 2. For this reason, even if the commodity G is heavy, an excessive load is not applied to the bottom plate 1 and the bottom plate 1 does not sink or break from the both side edges of the pressure receiving plate 2.

When the product G is light, the product G can be supported even if the projection 7 is omitted.

[0018]

As described above, when the cushioning material according to the present invention is placed on the bottom plate and packed so as to hang over the two pressure receiving plates by the above configuration, the tension from the two pressure receiving plates is applied to the bottom plate. Works, and the article is elastically supported by the bottom plate and the two pressure receiving plates, so that it can cope with heavy objects.

Further, since the pressure receiving plate and the end plate are adjacent to each other without the top plate interposed therebetween, they can be easily assembled.
