DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below in detail with reference to the drawings. 1 (A) and 1 (B) and FIG.
In the figures, reference numeral 1 denotes a cardboard bottom plate having a vertical portion provided on a peripheral edge thereof, and 2 denotes a styrofoam cushioning material disposed on the bottom plate 1, and a vertical side provided on the peripheral edge of the cushioning material 2 and the bottom plate 1. A substantially L-shaped insertion groove is formed between the four corners to insert and stand uprights to be described later.

Reference numeral 3 denotes a product having a relatively large mass, such as an outdoor unit of an air conditioner, which is mounted on the cushioning material 2. A continuously bent cardboard top plate, 6 is a column provided between the top plate 4 and the bottom plate 1 and has a substantially L-shaped cross-section, and 7 is a top portion of the top plate 4 from above. A packing box for packing the product 3 covered and protected by the top plate 4 and the like. Although not shown, the packing box 7 may be formed to have a shallow depth similarly to the bottom plate 1 and banded between the bottom plate 1 and the packing box 7. In place of using, a band may be hung between the top plate 4 and the bottom plate 1.

The top plate 4 has a top surface 4a, an outer surface 4b in which both left and right sides of the top surface 4a are bent downward by folds a, and a lower portion of both outer surfaces 4b by folds b. The first bottom surface 4c bent in parallel, the first middle surface 4d in which both ends of the first bottom surface 4c are bent upward by the fold c, and the tip of the first middle surface 4d in the both are bent by the fold d. A first middle ceiling surface 4e bent in parallel with the top surface 4a,
A second middle surface 4f in which the tip of 4e is bent in parallel with the first middle surface 4d by a fold e, and a lower portion of both second middle surfaces 4f are flush with the first bottom surface 4c by a fold f. A second bottom surface 4g bent in a shape, an inner surface 4h in which both ends of the second bottom surface 4g are bent in parallel with the second middle surface 4f by a fold g, and an upper portion of the both inner surfaces 4h are creased. h, which is bent outward and clamped by the top surface 4a and the first middle surface 4e, and a second middle surface having its tip abutted on the outer surface 4b.
4i, a rear outer surface 4j in which a rear portion of the top surface 4a is bent downward by a fold i, and a lower portion of the rear outer surface 4j by a fold j in the same plane as the first bottom surface 4c and the second bottom surface 4g. A substantially L-shaped mounting groove E comprising a rear bottom surface 4k, a groove formed between the first bottom surface 4c and the second bottom surface 4g on the rear bottom surface 4k, and a cutout provided continuously therewith. When,
The tip of the rear bottom surface 4k is creased at the rear outer surface 4j.
The rear inner surface 4m bent in parallel with the buffer inner surface 4n, the lower portion of the rear inner surface 4m is folded in parallel with the crest m by the fold m with respect to the top surface 4a, and the front end of the buffer surface 4n is bent by the fold n. The support surface 4o bent toward the top surface 4a and the support surface 4o, the buffer surface 4n, the rear inner surface 4m, the rear bottom surface 4k, the rear outer surface 4j, and the buffer portion formed by the top surface 4a, The top plate 4 has a configuration in which the cushioning surface 4n is placed in close contact with the upper portion of the product 3, and the upper portion of the support column 6 is fitted into the mounting groove E for mounting.

This eliminates the need to use a separate member made of styrene foam or the like for the buffer portion, so that the top plate 4 has a configuration suitable for recycling, and the lower portion of the column 6 has the substantially L-shape. It can be easily inserted into the insertion groove and can be erected, and the upper portion can be easily fitted into the mounting groove E, so that the workability of packing can be improved.

Further, since the mounting groove E is formed to have such a dimension that the support column 6 is fitted with almost no gap, the support column 6 can be fitted more accurately so as to prevent looseness (play). Therefore, the configuration is such that the packing box 7 can be easily covered.

A first locking piece C protruding outward is provided at the tip of each of the second middle ceiling faces 4i, and a corresponding one of the first locking pieces C is provided on both outer side faces 4b. By providing the first locking hole A and locking the first locking piece C in the first locking hole A, the top plate 4 can be formed accurately and firmly. It has a configuration.

Further, by providing a plurality of the first locking pieces C and the first locking holes A, the top plate 4 can be formed more accurately and more firmly. I have.

A second locking piece D protruding outward is provided at both ends of the rear inner surface 4m, while a second locking piece D is provided.
A second locking hole B is provided in each of the inner side surfaces 4h in correspondence with the above, and the second locking piece D is locked in the second locking hole B. And can firmly hold the rear inner surface 4m and the cushioning surface 4n,
The configuration is such that the buffer effect of the buffer section can be further improved.

Further, outwardly protruding third locking pieces D 'are provided at both ends of the support surface 4o, while third locking pieces D' are provided on both inner side faces 4m corresponding to the third locking pieces D '. By providing a locking hole B ′ and locking the third locking piece D ′ in the third locking hole B ′, the top plate 4 can be accurately formed and the support surface 4o and the buffer surface 4n can be held firmly, so that the buffer effect of the buffer portion can be further improved.

When the mass of the product 3 is smaller than that of an outdoor unit of an air conditioner or the like, the bottom plate 1
The top plate 4 may be arranged on the bottom plate 1 instead of the cushioning material 2 arranged on the bottom plate 1. In this case, it is not necessary to use the cushioning material 2 made of polystyrene foam, so that the bottom plate 1 can be adapted to recyclability like the top plate 4 and has a more advantageous configuration in terms of cost. .

With the above arrangement, the cushioning portion for protecting the top plate 4 and the product is continuously bent by cardboard, and the mounting groove E is continuously formed in the top plate 4. Since the top plate 4 does not use a polystyrene foam cushioning material, the top plate 4 is configured to be compatible with recycling, and the support column 6 can be easily and accurately fitted and attached to improve the workability of packing. It becomes a packing device.

[0025]

As described above, the packing device is constructed such that the top plate and the cushioning portion are continuously bent and made of cardboard so as to be suitable for recycling, and the columns can be easily attached.
