DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the method of the present invention will be described below with reference to FIGS.

First, FIG. 1 shows a base material 21 of a bottom box of a clothes dryer packaging apparatus, which is made of, for example, corrugated cardboard having a step 22 and has a rectangular shape elongated in the left and right directions.

For this reason, the base material 21 is provided with the kerfs 23 for box making on the front and rear parts on both left and right sides, and the folding curve 24 is machined between the left and right kerfs 23, 23 on the front side. Connect between the left and right cut grooves 23, 23 and apply to both front and back parts,
Further, the folding curve 25 is processed by connecting the front and rear kerfs 23, 23 on the left side and the front and rear kerfs 23, 23 on the right side and further extending it to the front edge and the rear edge of the base material 21 to both the left and right parts. I am giving it.

Further, in the base material 21, as will be apparent later, each kerf 23 which is a portion which becomes a corner when the box is manufactured.
The reinforcing material 26 is applied in a strip shape of the same width in this case to the portions on both sides and the portions on both sides of the folding line 24, which are the ridge portions having the portions not in contact with the cushion.

Here, in detail, the reinforcing material 26 is made of a resin melt such as a paraffin resin, a water-repellent resin, or a thermoplastic resin, and its application is, as shown in FIG. A container 27 containing the above-mentioned resin melt in an apparatus for processing the kerf 23 and the bending curves 24, 25, and this container 2
By providing a plurality of rollers 28 for applying the resin melt from inside 7 and applying it to the base material 21, the same process as the processing of the base material 21 can be performed.

After the reinforcing material 26 applied to the base material 21 is solidified in this manner, the base material 21 is bent from the folding curves 24 and 25, as shown in FIG. Also fold. Then, the overlapping portions due to this bending are stopped by a plurality of staples 29, respectively, to make a box, and a bottom box 30 of the packaging device for a clothes dryer is manufactured.

As shown in FIG. 4, a lower cushion 31 is placed on the inside of each of the ridges on the left and right sides of the box 30 made in the box, as shown in FIG. To package.

As described above, in this method, the reinforcing material 26 is applied to the corner portions of the base material 21 and the ridge portions having the portions which the lower cushion 31 does not contact, and the reinforcing material 26 is applied. By bending (strengthening) the reinforcing material 26 by coating (solidifying), the corners of the bottom box 30 to be strengthened and the ridges having the portions not in contact with the cushion are strengthened, and fall as described above. Since it will not be damaged during handling or handling of cargo, the packaged object will not be deformed or dented, and its protection can be ensured.

Moreover, in this case, all that is required is the reinforcing material 26 that is applied to the required portion of the base material 21, and in addition to the conventional reinforcing tape, there is no need for further reinforcing cushions. Therefore, the material cost can be reduced and the cost can be reduced.

Further, the application of the reinforcing material 26 can be performed in the processing step of the base material 21 before the box making, and the work after the box making is not required. Compared to the conventional one, which has the trouble of attaching and fitting the reinforcing cushion, the number of working steps can be reduced, and the cost can be further reduced.

FIG. 5 shows another embodiment of the present invention. Instead of providing the reinforcing material 26 on the base material 21, for example, a plastic sheet, a plastic film, a cloth, a plastic fiber, or a metal is used. A reinforcing material 32 made of a film, synthetic paper, laminated paper, cardboard, plastic tape, paper tape, etc. is provided by adhering with an adhesive. Even in this case, the same effect as described above can be obtained. Obtainable. Also, in this case, the reinforcing material 3
2 can be rolled and attached in the same step as the processing of the base material 21 as in FIG.

Further, although not shown, due to the size of the article to be packaged, in the case where the portion of the folding curve 25 is as long as the portion of the folding curve 24, and the lower cushion 31 is also arranged apart from this portion, The reinforcing material 26 may be applied or the reinforcing material 32 may be attached to the portion of the folding curve 25.

In addition, for attaching the reinforcing material 32, a method may be adopted in which a polyethylene film is composite-laminated and heat-welded with a roller instead of using an adhesive.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be appropriately modified and implemented without departing from the scope of the invention.
