Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing device used for packing an air conditioner or the like.

[0002]

2. Description of the Related Art For packing an air conditioner, for example, a packing device as shown in FIG. 6 is used. This packing device includes a bottom lid 21 that protects the bottom of the air conditioner that is the object to be packaged, an external cardboard 22 that covers the object to be packaged, and a reinforcing member that strengthens the corners (between the four corners above and below) of the external cardboard 22. (Corner reinforcing material) 23, and a band (not shown) that is wound around and fastened to the outside of the exterior cardboard 22, and the like. The bottom lid 21 is composed of a cardboard box 24 and a pair of cushioning materials 25, 26, etc. arranged at opposite corners inside the box 24. An inner flap 27 and an outer flap 28, which are placed on the upper part of, are continuously provided. As the packing procedure, the packaged object is placed on the bottom lid 21, and then the external cardboard 22 is covered, and the reinforcing members 23 separately formed are inserted into the four corners of the external cardboard 22,
The inner flap 27 and the outer flap 28 are bent to the upper portion of the body to be packaged, and a band (not shown) is wound and fastened to the outside of the outer cardboard 22.

[0003]

However, in the above configuration, the shape of the exterior cardboard 22 is not stable during packaging, and it takes extra time to engage with the bottom lid 21. In addition, since the separately formed reinforcing members 23 must be inserted into the four corners of the exterior cardboard 22, workability is poor and the cost is high. Further, in order to form the exterior cardboard 22 as shown in FIG. 1, an auxiliary member such as a stitch or an adhesive is required at the connecting portion on the side surface, and the productivity is poor. Therefore, it is an object of the present invention to provide a packaging device that solves these problems.

[0004]

The present invention has been made to solve the above-mentioned problems, and a pair of cushioning materials for protecting the bottom of the packaged object are arranged at the opposite corners of the bottom of the box. Of the outer lid, which is provided with a flap that covers the upper portion of the packaged body, a reinforcing member that reinforces the corners of the packaged cardboard, and an outer cardboard that covers the bottom lid and the packaged body. In a packing device including a band that is wound and fastened to the outside, a reinforcing portion that replaces the reinforcing member is continuously provided at a corner portion of the exterior cardboard.

[0005]

With the above construction, the corner portions of the outer cardboard are connected to the reinforcing portions for strengthening the corner portions, so that the corners of the outer cardboard can be eliminated without using a separately formed reinforcing member. The corners can be strengthened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a packing device for an air conditioner (hereinafter referred to as a packaged object), 1 is a bottom cover for protecting the bottom of the packaged product, and 2 is a packaged product placed on the bottom cover 1. It is an outer cardboard that is covered from above. The bottom lid 1 is composed of a cardboard box body 3 and a pair of cushioning members 4a and 4b provided at opposite corners inside the box body 3. The outer cardboard 2 has four front, rear, left and right side surfaces 5, 6,
7, 8 and an inner flap 9 and an outer flap 10 which are put on the upper part of the article to be packaged, and a reinforcing portion 1 which reinforces corner portions.
1 and is expanded into a shape as shown in FIG.

The reinforcing portion 11 has two side surfaces 6 which are orthogonal to each other.
And 8,8,5,5,7,7 and 6 and two inner folding surfaces 11a which are respectively bent, and these two inner folding surfaces 11a to 1
1a and a connecting surface 11b continuously provided between them, and by bending these in a predetermined direction, a hollow triangular reinforcing portion 11 as shown in FIG. 1 is formed. However, FIG.
It is necessary to regulate the movement of the reinforcing portion 11 to some extent in order to hold the product processed as shown in FIG. 1 in the shape as shown in FIG. Therefore, in this embodiment, each side surface 5,
A plurality of locking pieces 12 are provided on the left and right sides of 6, 7, and 8, and the same number of locking holes 13 are provided on the inner folding surface 11a forming the reinforcing portion 11, and the locking pieces 12 are engaged as shown in FIG. Stop hole 13
The movement of the reinforcing portion 11 is regulated by pushing it toward and locking it.

FIG. 4 shows the shape of the exterior cardboard 2 at the stage of covering the bottom cover 1 from above. At this stage, since the corners (between the side surfaces) of the outer corrugated cardboard 2 are separated and the whole is in a swollen state, it is possible to easily cover the bottom lid 1. The outer corrugated cardboard 2 covered by the packaged object is covered with the inner flap 9 and the outer flap 10 on the upper part of the packaged object, and the side surface is compressed by winding and fastening the band 14 at the position shown in FIG. The gaps between the corners that were open up to that point are almost eliminated, and the reinforcing part 1 provided inside
Since the movement of 1 also stops, sufficient strength can be obtained.

[0009]

EFFECT OF THE INVENTION In the case of the external corrugated cardboard as described above, sufficient strength can be obtained without using a reinforcing member or the like formed separately, and the handling is easy. In addition to cost reduction, no auxiliary members such as stitches are used for assembling this outer cardboard, so separation and disassembly can be easily performed after the function is finished, which is also useful for resource recovery.
