Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing cushion for storing articles together with the articles in an outer box to protect the articles from impact.

[0002]

2. Description of the Related Art As a buffer of this type, a buffer described in Japanese Utility Model Laid-Open Publication No. 6-10175 has been conventionally known. As shown in FIG. 7, this buffer body raises the outer plate 51 from both side edges of the substrate 50 and the end plate 52 from both end edges, and also connects the outer plate 51 and the end plate 52 with the oblique line 53 and the vertical line 54. The top plate 56 is connected inward from the upper end edge of the outer plate 51 and the inner plate 57 is connected downward from the inner end edge of the top plate 56, and the lower end edge of the inner plate 57 is connected. Paste the glue margin piece 58 going inward from the substrate 50,
The outer plate 51 and the end plate 52 are cut by cutting the substrate 50.
The leg piece 59 protrudes downward from above.

However, those which require an adhesive step during manufacture, such as the above-mentioned shock absorber,
There is a problem that the cost increases.

Accordingly, an object of the present invention is to provide a shock absorber that can be manufactured without bonding.

[0005]

In order to solve the above-mentioned problems, a buffer according to the present invention has an outer plate provided on both side edges of a substrate and an outer end plate provided on both end edges thereof, and a front end of the outer plate. A top plate and an inner plate are sequentially connected to the edge, and the outer end plate and the outer plate are connected by connecting pieces via oblique lines and vertical fold lines. Cut the edge from the edge into the board to form leg pieces, fold the oblique line and the vertical fold line into mountain folds and valley folds, respectively, raise the outer plate and the outer end plate with respect to the substrate, turn the top plate inward, and attach the inner plate. By sequentially bending downward and inserting the insertion piece into the extraction hole of the leg piece, the inner plate is prevented from returning due to rebound.

If a bulging portion is provided at the inner end edge of the extraction hole, it is possible to easily assemble the flat state in which the insertion piece is engaged with the bulging portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the blank shown in FIG. 1, an outer plate 2, a top plate 3 and an inner plate 4 are provided on both side edges of a substrate 1, and an outer end plate 5, a top plate 6 and an inner end plate 7 are provided at both end edges. Each is sequentially connected. The outer plate 2 and the outer end plate 5 are connected by a connecting piece 8, and the boundary between the connecting piece 8 and the outer end plate 5 and the outer plate 2 is an oblique fold line 9 and a vertical fold line 10, respectively.

[0008] Insert pieces 11 are protruded from the distal end edge of the inner plate 4, and leg pieces 12, 13 are cut into the base 1 center and both end portions of the outer plate 2 toward the substrate 1, respectively. Is provided. The tip of the leg piece 12 is
4, the outer plate 2 is provided with shoulders 15 on both sides of the top plate 3 at the leading edge of the outer plate 2. Leg pieces 16 are provided at both ends of the front end edge of the inner end plate 7.

In order to assemble the blank as shown in FIG. 4, the outer plate 2 and the outer end plate 5 are simultaneously erected on the substrate 1 as shown in FIGS.
The oblique fold line 9 and the vertical fold line 10 are folded in a mountain and a valley, respectively, so that the connecting piece 8 extends along the inner surface of the outer end plate 5. Here, with the erecting of the outer plate 2, the extraction holes 17, 18 for the leg pieces 12, 13 are formed in the substrate 1.

Then, the top plate 3 is bent inward and the inner plate 4 is sequentially bent downward, and the insertion piece 11 is inserted into the extraction hole 17.
In this state, the insertion piece 11 is pressed by the bulging portion 14 and the return of the inner plate 4 due to rebound is prevented.

Thereafter, the top plate 6 is bent inward and the inner end plate 7 is sequentially bent downward, and the top plate 6 is supported by the shoulder portion 15 and the leg pieces 16 are supported.
Into the extraction hole 18 to complete the assembly.

Prior to the erecting of the outer plate 2 and the outer end plate 5, the inner plate 4 is bent inward so that the insertion piece 11 is
Piled up and stored in a flat state engaged with 4,
If necessary, assembly can be performed from this state, and in this case, assembly can be performed quickly.

As described above, this buffer can be assembled into a shape as shown in FIG. 4 without bonding any portions.

In this assembled state, as shown in FIGS. 5 and 6, when the article G is stored in the outer box B and the article G is packed, the gap between the peripheral wall of the outer box B and the inner plate 4 and the inner end plate 7 is reduced. In addition, a buffer space is formed between the bottom wall of the outer box B and the substrate 1, and the peripheral wall of the buffer has a double structure, so that the article G is reliably protected from external impact and the like. .

[0015]

As described above, the shock absorber according to the present invention is provided with the insertion piece at the end edge of the inner plate connected to the side edge of the substrate via the outer plate and the top plate, and this insertion piece is provided. By inserting it into the extraction hole of the leg piece formed on the substrate, the return of the inner plate was prevented, so the bonding process was unnecessary,
Can be manufactured at low cost.
