Description

[Detailed Description of the Invention] This invention relates to improvement of cardboard packaging for electric refrigerators and the like.

This type of conventional cardboard packaging is explained with reference to FIGS. 1 to 4. 1 is a refrigerator body as an object to be packaged, 2 is a cardboard base plate on which the refrigerator body is placed, and 3a and 3b are the cardboard base plates. Bottom cushioning materials 4a * 4b are fixed to the inner surfaces of the side plates and the bottom surface 5 of the corrugated base plate with adhesive or the like.

? Reinforcements a and 7b are provided in the width direction to reinforce the bottom surface 5 of the cardboard base plate and the side plates 3, and the bottom cushioning materials 4a,
It is fitted into a notch 9 formed at the end of 4b and fixed by adhesive.

10 is a notch formed in the center of this reinforcing rod, and the reinforcing rod 1 has stepped portions 11 formed at both ends to fit into this notch.
2 is placed.

In addition, an upper cushioning material 13a is provided on the opposite side of the upper corner of the refrigerator main body 1.
t 13b and insert the cardboard case 1 from the outside.
4, and the whole was fastened with a fastening band 15 for packaging.

For this reason, the reinforcing material 7a is used as reinforcement for the corrugated board base plate 2.
Since the notches 10.degree. 11 are fabricated in the T 7b and reinforcing rods 12, etc., there is a drawback that the cost of the package is extremely high.

This invention is aimed at eliminating the above-mentioned drawbacks, and will be explained with reference to the embodiment shown in FIGS. For the rear plate, in order to perform this reinforcement on the cardboard base plate 2 itself, the tips of the front and rear plates are each bent inward into a U-shape, and a notch 16 is made in the center of each edge of the front and rear plates. is forming.

The cardboard base plate 2 is constructed by fitting both ends of the reinforcing rods 12 into the notches of these front and rear plates.

Further, since the front plate 6a and the rear plate 6b are supported at their corners 8 by bottom cushioning materials 4at4b installed on both sides of the cardboard base plate 2, the bent portions do not open inward.

Since this invention is constructed as described above, it can be used as reinforcement for the bottom, front and rear plates of a corrugated board base plate, as in the past.
It is possible to omit reinforcing rods such as wood, which were previously arranged, and also eliminate the need for secondary processing, resulting in a significant cost reduction.
