Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package, and more particularly to a package for a relatively heavy object such as an electric refrigerator.

Conventionally, this type of packaging has been made up of cardboard boxes as shown in Figure 1.
A bottom cushioning material (not shown) is completely fixed to a bottom plate (not shown) made of L- or the like to form plywood 2, and an object to be packaged 1 such as an electric refrigerator is placed on the bottom cushioning material. Ω Cover the protective bag 4 from above the object to be packaged 1, then attach the upper cushioning material 5 to the upper corner of the opposite side of the object to be packaged, cover the cardboard case 9 from above, and place the upper flap of the case 9 at the top flap joint. It was formed by sealing 1 with a full-paper adhesive tape 10 and tightening the cardboard case 9 and base plate 2 with a fastening band 8.

As described above, conventional packaging requires a cardboard case that covers most of the items to be packaged, which has become a major cost increase factor as refrigerators and the like have recently become larger.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging number that makes it possible to pack items without using a cardboard case that covers the items, in order to solve the problem of slanting conventional methods. .

Hereinafter, the packaging body of the present invention will be explained in more detail with reference to preferred embodiments shown in the accompanying drawings.

A package 20 according to one embodiment of the present invention is shown in FIGS. 2-4.

The package 20 of this embodiment includes a base plate 22 and a top plate 23 made of corrugated paper, which are placed on the bottom and top of an object 21 to be packaged, such as an electric refrigerator. The base plate 22 and the top plate 23 each have a side wall portion 2 rising from the surrounding side line.
2a and 23a, and has a lid-like shape as a whole. Inside this base plate 22, there is a pair of side walls 2 facing each other.
Two bottom cushioning members 24a and 24b made of foamed polystyrene or the like and having a relatively high height are arranged along 2aim, and the object to be packaged 21 is arranged so that its bottom surface is aligned with the base plate 22, and the bottom cushioning members 24a, 24b.

Incidentally, there are spaces between the side wall portion 22g of the base plate 22 and the three surfaces of the bottom buffer members 24a and 24b facing the side wall portion 22g so as to form a fitting groove 25.

Further, the top plate 23 is arranged so that the object to be packaged 21 is covered with a protective bag 26 made of soft polyethylene film or the like, and then the object to be packaged is
At this time, similar upper cushioning members 27a and 27b are placed on the top surface of the packaged object 21 along the opposite corners of the bottom surface on the same side as the bottom cushioning member. Spaces are provided between the side wall portion 23a of the top plate 23 and three surfaces of the upper buffer members 27a, 27b facing the grooves so as to form a fitting groove 28.

Further, the package 20 includes a pair of side plates 291 that cover at least the opposite side surfaces of the object to be packaged 21, and the side plates 29 have their upper ends fitted into the above-mentioned fitting grooves 28, and the other ends entirely fitted into the above-mentioned fitting grooves 25. It has been installed.

As shown in FIGS. 3 and 4, this side plate 29 has a main surface 29a (((mountain folded) so as to form a main surface 29a ((( Fold it along the line 29b, and then fold it back along the mountain fold line 29C, so that it hits the two side surfaces connected on both sides of the side surface of the packaged object 21.
A rank portion 29d is formed. Said 7 rank part 29d
The corrugated paperboard sheet is folded back to have a double thickness, and the corrugated paperboard sheet side parts are further folded along the valley fold line 29e so that the side line is positioned inside the main surface 29a. Therefore, the predetermined widths on both sides of the main surface 29a also have double thickness. Adhesive is applied to the edge portions of the corrugated cardboard sheet on both sides, that is, to the inner surface of the folded piece, and is fixed at the 7-rank portion and a part of the main surface to which the folded piece is tightly attached.

The order of assembling the package 20 having such a configuration is as follows:
After covering the protective bag 26 with the protective bag 26, the upper cushioning members 27a and 27b are placed on both shoulders of the upper surface of the packaged object 21. Thereafter, each side plate 29 connects its lower end to the side wall portion 22a of the plywood 22 and the bottom buffer member 24a.

It is attached by being fitted into the fitting groove 25 between the respective three sides of 24b, and then the top plate 23 is placed on it. Finally, as shown in FIG.
1 in the vertical direction, and each component of the package 20 is integrally assembled and fixed to the packaged object 21.

FIG. 5 shows one side plate of a package according to another embodiment of the present invention.
is shown. The side plate 31 in this embodiment is almost the same as the side plate 29 in the embodiment shown in FIG. 4, except that as is clear from FIG. The difference is that when the seventh rank part 32 is folded back, a columnar reinforcing material 33 made of wood or processed paper is wound inside the seventh rank part 32 to form the flange part 32.

According to such a side plate 31, the 7-rank portion 32 of the side plate is further reinforced than in the embodiment shown in FIG. 4, and the strength of the side plate can be increased.

Further, FIGS. 6 and 7 show a side plate 35 in a package according to still another embodiment of the present invention. This side plate 35 has 7-rank parts 36 on both sides of the corrugated cardboard sheet.
When folded back from the edge of the side plate, the reinforcing material 32 is rolled up and folded back in the same way as the side plate 31 in FIG. is brought into contact with the surface. However, at the edge of the folded piece,
The convex portion 37 is integrally formed, and a hole 38 into which the convex portion 37 is fitted is formed on the main surface which the contact edge abuts. The end edge of the return piece connects the protrusion 37 to the hole 38 on the main surface 35a.
It is fixed by inserting it into the

According to this, the 7-rank portion 36 of the side plate can be easily formed without particularly using adhesive or the like.

As described above, according to the packaging body of the present invention, it is possible to transport relatively heavy items such as medium to large electric refrigerators without using large cardboard cases as in the past. A fully durable package can be provided.

Moreover, since the packaging body of the present invention can be manufactured regardless of the scale of the corrugated board processing company, it is easy to reduce the cost of the packaging material, and the economic effect is also very large.
