Abstract

PROBLEM TO BE SOLVED: To hold compressive strength of an outer corrugated fiberboard by preventing a corner reinforcing board standing at four corners of the outer corrugated fiberboard from tilting. SOLUTION: An air conditioner body 3 is mounted on a lower cushion 2 in a bottom plate corrugated fiberboard 1, an outer corrugated fiberboard 4 is put over from an upper part of the air conditioner body 3, and a side of each corner reinforcing board 7 is inserted between an inner angled face and the lower cushion 2 to make them stand. Upper cushions 8a, 8b are put over left and right of an upper part of the conditioner body 3, a top plate 9 is put on them, and an upper end of the corner reinforcing board 7 is inserted through an L-shaped hole 10 provided at four corners of the top plate 9, thereby preventing the corner reinforcing board 7 from tilting. Finally inner flaps 5a, 5b and outer flaps 6a, 6b of the outer corrugated fiberboard 4 are folded onto the top plate 9 and a band is wound around the outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging device for an air conditioner, and more particularly to means for increasing the compressive strength of the device.

[0002]

2. Description of the Related Art In packaging an air conditioner, for example, a box-shaped bottom plate corrugated cardboard 21 as shown in FIG. 3 and a lower portion which is disposed on the left and right inside the bottom plate corrugated cardboard 21 to support an air conditioner main body 23. The buffer 22 and the air conditioner body 23
And a pair of upper cushions 24a and 24b for covering the corners from the impact and the like by covering the upper left and right sides of the
An exterior cardboard 27 having an inner flap 25 and an outer flap 26 that are bent on the upper surface of 24b, and a lower part inserted between the inner corner surface of the bottom plate cardboard 21 and the lower cushioning body 22,
A band (not shown) is wound around the exterior cardboard 27 and fastened by using a corner reinforcing plate 28 having an L-shaped cross section in which the upper inner surface is brought into contact with the outer corner surface of the corresponding upper cushioning body 24a or 24b. It is supposed to do.

[0003]

By the way, the above-mentioned corner reinforcing plate 28 is provided to protect the corner portion of the air conditioner main body 23 from external pressure and to strengthen the vertical compressive strength of the exterior cardboard 21. However, in the above configuration, a gap corresponding to the paper thickness (cardboard paper thickness) of the bottom plate cardboard 21 is formed between the upper outer surface of the corner reinforcing plate 28 and the inner surface of the exterior cardboard 27.
It is expected that the corner reinforcing plate 28 does not always stand vertically, but may tilt. If the corner reinforcing plate 28 is in an inclined state, the above-mentioned compressive strength may be reduced, and the outer corrugated cardboard 21 may be deformed or the load may collapse. Therefore, an object of the present invention is to provide an air conditioner packing device that does not cause such a problem.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a packing device for an air conditioner is housed in a box-shaped bottom plate cardboard and the same bottom plate cardboard. An exterior including a lower cushion that supports the main body of the air conditioner, a pair of upper cushions that are arranged on the left and right of the upper portion of the main body of the air conditioner, and an inner flap and an outer flap that are bent over the upper surface of the upper cushion. A corrugated cardboard and a corner reinforcing plate having an L-shaped cross section in which the lower part is inserted between the inner corner surface of the bottom cardboard and the lower cushion, and the upper inner surface is brought into contact with the outer corner surface of the upper cushion, and the same corner reinforcement. The top plate having L-shaped holes through which the upper end of the plate is inserted and held is provided at the four corners.

[0005]

With the above construction, the main body of the air conditioner is placed on the lower cushioning body in the bottom cardboard, the exterior cardboard is covered from above the main body, and one side of the corner reinforcing plate is used as the inner corner surface of the bottom cardboard. Insert between the lower cushions to stand up, place the upper cushions on the left and right of the upper part of the air conditioner main body, cover the upper cushions with the top plate before bending the inner flap and the outer flap of the exterior cardboard, and By inserting the upper end portion of the corner reinforcing plate into the L-shaped holes provided at the four corners of the corner, the inclination of the corner reinforcing plate can be prevented, and desired compression strength can be maintained.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an air conditioner and its packing device, 1 is a box-shaped bottom plate corrugated cardboard, 2 is a foamed resin lower cushion disposed on the left and right inside the bottom plate corrugated cardboard, and 3 is air The main body of the harmony machine, 4 is an outer corrugated cardboard having inner flaps 5a, 5b and outer flaps 6a, 6b on the upper part, 7 is a corner reinforcing plate made of corrugated cardboard, 8
a and 8b are upper cushions made of foamed resin that protect the upper left and right corners of the air conditioner body 3 from external pressure, and 9 is a top plate made of cardboard that covers the upper cushioners 8a and 8b. The four corners of 9 are L corresponding to the upper end of the corner reinforcing plate 7.
A V-shaped hole 10 is provided.

As a packing procedure of the air conditioner main body 3, the air conditioner main body 3 is placed on the lower cushioning body 2 in the bottom plate cardboard 1, and the outer cardboard 4 is covered from above the main body 3.
One side of each corner reinforcement plate 7 is the bottom plate cardboard 1
Is inserted between the inner corner surface and the lower cushion 2 to stand upright, and the upper cushions 8a and 8b are covered on the upper left and right sides of the air conditioner body 3,
A top plate 9 is put on the top plate 9, and the upper ends of the corner reinforcing plates 7 are inserted into the L-shaped holes 10 provided at the four corners of the top plate 9, and finally the top part of the exterior cardboard 4 is provided. The inner flaps 5a, 5b and the outer flaps 6a, 6b are bent on the top plate 9 and banded to the outside.

FIG. 2 shows another embodiment.
1 is different from FIG. 1 in that the top plate 9 is not used, but a bent piece 7a that is bent outward is provided on the upper portion of each corner reinforcing plate 7, and the front side of the bent bent piece 7a contacts the inner surface of the outer cardboard 4. The corner reinforcing plates 7 can be erected upright by contacting and pushing. The corner reinforcing plate 7 is the bottom plate cardboard 1.
Made of cardboard paper with the same thickness as. With the packing apparatus of FIGS. 1 and 2 described above, the corner reinforcing plate 7 can be prevented from tilting, and a desired compressive strength can be maintained.

[0009]

According to the packing apparatus as described above, since the corner reinforcing plate is prevented from tilting, the compressive strength is stable, and the outer cardboard is not deformed or collapsed.
