Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging cushion that is set, for example, at the inner bottom of a packaging box to accommodate cassettes, trays, etc. that are accessories of a copying machine.

Normally, when packing a copying machine, relatively strong accessories such as cassettes and trays are placed in a packaging buffer and then stored in a packaging box together with the copying machine main body.

However, when making this type of packaging cushioning material, the overlapping plates are conventionally fixed to each other by staples (wire) or glued together, but the following method is used: There are some drawbacks.

That is, the former wire-fastened type has drawbacks such as large variations in Al dimension, poor workability, c) requires skill, and high cost.

In addition, those using the latter adhesive are as described above {a~'d}
In addition, {e} Adhesive odors and smoke are generated, impairing the working environment. 'f} Adhesive adheres to the body and causes a rash. 'g} For example, 60oo like hot melt adhesive
If the temperature exceeds this level, the adhesive loses its adhesive function and is likely to peel off, resulting in a disadvantage such as a lack of reliability. The present invention has been made based on the above-mentioned circumstances, and aims to provide a structure that is relatively simple, can be assembled using an adhesive without using wire, has excellent strength, and is easy to assemble. The present invention aims to provide a cushioning material that is easy to package.

This is a cut line formed at the border between a to 8e.

Next, a procedure for assembling the packaging cushion 1 from the single substrate 6 configured as described above will be explained.

First, the rectangular plate parts 8a to 8e are sequentially folded along the fold lines a to e.
The reinforcing tube 8 is formed by bending the reinforcing tube 8 along the fold line i, and the reinforcing tube 8 is made into a rectangular tube shape, and the band-like slope portions 7a, 7a are made to stand up along the fold lines i, i, to form the state shown in FIG. At this time, after sequentially bending the rectangular plate portions 8a to 8e as shown in FIG. 5, the rectangular slope portion 8 of the reinforcing tube 8...
b is securely overlapped with the strip plate 7a forming one side wall 7 of the storage chambers 3 and 4, and the locking tongues 12 and 13 are bent together, thereby fixing these plates to each other in advance. next,
As shown in FIG.
A pair of rectangular tube-shaped object support parts 5, 5 separated from each other are formed by sequentially bending the support parts 5, 5 in the same direction through the support parts 5, 5, and a cut-and-raised piece 10a formed between these support parts 5, 5. The partition pieces 10 are formed by standing up the partition pieces 10. At this time, the reinforcing cylinder 8 is wrapped inside the packaged object support parts 5, 5. Next, the projecting pieces 10b, 10b formed at the top of both ends of the partition piece 10 are inserted into the insertion holes 11, 11 formed in the mutually opposing plate surfaces of the packaged object supporting parts 5, 5,
As shown in FIGS. 9 and 10, the packaged object support section 5,
5 from floating and the partition piece 10 from falling down. Then, the packaging cushion 1 as shown in FIG. 2 can be assembled without using adhesive or wire.

In addition, in the above-mentioned embodiment, although the case where the case is stored at the bottom of the packaging box has been described, the present invention is not limited to this.
It may be stored on the top or side of the packaging box.

Further, although the number of storage chambers is two, the number may be increased by increasing the number of partition pieces. In addition, as a method for fixing the overlapping plates together, the locking pieces were bent all at once, but as shown in FIGS. 11 and 12, the locking pieces 12 are provided on one plate, and the locking pieces 12 It may be fixed by bending and inserting it into the trapezoidal hole 16 of the body.

As described above, the present invention includes a pair of prismatic cylindrical object support parts that are separated from each other by folding both ends of the substrate multiple times, and a support part of the substrate that corresponds to the support parts for the packaged object. The side walls, which are bent at both ends to form a storage section between the support parts for the packaged object, and the band-shaped parts, which are bent at both ends of these side walls, are folded multiple times to form a polymer. The reinforcing cylinder interposed inside both ends of the package support part and the green end of the folded overlapping part of this reinforcing cylinder are each made a cut in the direction perpendicular to the bending direction of the band-shaped part to determine the width dimension of the free end side. The reinforcing cylinder is formed with a locking tongue whose width is larger than the width of the base portion, and which are fixed together by overlapping each other by bending the reinforcing tube all at once.

Therefore, although the structure is relatively simple, it can be made thin without using adhesive or wire.

Furthermore, since the reinforcing tubes are interposed inside both ends of the packaged object support section, sufficient support strength can be obtained.

Furthermore, since the reinforcing cylinder is fixed by the locking tongue, the reinforcing cylinder does not spread out when the article support part is bent and formed, and the assembly workability is excellent.

Further, in the state where the assembly is completed, the packaged object support portion covers the locking tongue of the reinforcing cylinder, so that the reinforcing cylinder is fixed even more securely.
