Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing device, and more particularly to a lower packing material.

[0002]

2. Description of the Related Art A packing device for an outdoor unit of an air conditioner is shown in FIG.
As shown in FIG. 2, the outdoor unit 19 is placed on the bottom surface packaging material 20 in which the cushioning material 15 made of expanded polystyrene material is fixed on both sides of the U-shaped corrugated board material 18, and the upper packaging material 21 is placed on the upper surface of the outdoor unit 20. The band 22 is wound around and fixed to both sides of the packing material. However, the corrugated board material 18 of the bottom portion 20
There is a problem in that the end face of the central portion of the cardboard is likely to be blunted and the weight of the outdoor unit 19 causes the waist of the central portion of the corrugated cardboard material to be bent.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides a packing device having an improved structure of a lower packing material, which is less likely to be scratched or blunted and which is strong. To do.

[0004]

In order to solve the above-mentioned problems, the present invention folds a sheet of paperboard into a U-shape to form a front surface portion, a bottom surface portion and a rear surface portion, and the front surface portion has an edge. While bending the formed front reinforcing plate inward, bend the rear reinforcing plate formed at the rear end edge inward, and the front plate of the rear reinforcing plate and the bottom plate locking the front end of the front reinforcing plate. It is made of a rectangular cushioning material, and is characterized in that the cushioning material is fixed to both inner sides of the bottom plate.

[0005]

With the above construction, the packing apparatus according to the present invention has improved strength against bending stress of the lower packing material and has no end surface as a site where breakage or damage easily occurs. You can

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a development view of a bottom plate 1a made of a corrugated board member that constitutes a lower packaging material 1 of a packaging device according to the present invention. A bottom surface 2, a front surface 3, and a back surface 4 are formed continuously in a rectangular shape with the fold lines 5 and 6 as boundaries. A front reinforcing plate 7 is provided in the central portion with the polygonal line 10 as a boundary from the front portion 3.
Is provided, and a tongue piece 12 is provided at the edge of the front reinforcing plate 7.
Is projected. A rear reinforcing plate 8 is provided so as to face the front reinforcing plate 7 with a polygonal line 11 as a boundary from the back surface portion 4, and corresponds to the tongue piece 12 along a central polygonal line 9 of the rear reinforcing plate 8. A locking hole 13 is formed.
Further, the rear reinforcing plate 8 is provided with pressing portions 14 on both left and right sides. As shown in FIG. 2, the cushioning material 15 is a cushioning material formed of a styrofoam material in the shape of a rectangular parallelepiped and having a groove 16 in the center thereof. The cushioning material 15 is fixed to both inner sides of the bottom plate 1a by adhesion or the like, and falls onto the product. Absorbs shocks such as vibrations and vibrations to prevent product defects.

A procedure for assembling the lower packing material 1 will be described. As shown in FIG. 2, the front part 3 and the back part 4 are bent inward along the fold lines 5 and 6 of the corrugated board member 1a so as to face each other. Next, the bent line 11 is bent inward, and the bent line 9 is bent outward so that the front portion 8a of the rear reinforcing plate 8 is superposed on the bottom surface portion 2. Further, the pressing portion 14 is bent upward. Next, the folding line 10 is bent inward, and the tongue piece 12 is inserted and locked in the locking hole 13. Finally, the cushioning material 15 is adhered to the inside of the bottom surface portion 2, the front surface portion 3 and the back surface portion 4 by an adhesive material so that one side contacts the pressing portion.

The outdoor unit is placed so that the legs are fitted in the grooves 16 of the cushioning member 15 of the lower packaging material 1, and the upper packaging material is placed on the upper surface of the outdoor unit to clamp the product, Is wrapped around both sides of the upper packing material and the lower packing material and fixed to complete the packing.

FIG. 3 is a view showing a state where the lower packing material is assembled. Due to the structure in which the front reinforcing plate 7 and the rear reinforcing plate 8 are opposed to each other and incline downward and intersect each other on the bottom surface part 2 and are locked, the bending strength of the corrugated board material is several stages as compared with the conventional one. It is possible to improve, and it is possible to reduce the problem that the corrugated board material is bent at the waist due to the weight of the product, and it is possible to prevent problems such as breakage and scratches that are likely to occur on the end face because there is no end face portion.

[0010]

As described above, in the lower packing material of the packing apparatus according to the present invention, the front reinforcing plate and the rear reinforcing plate formed on the corrugated cardboard member are crossed and locked to each other, so that Strength against bending stress increases,
The breakage phenomenon of the corrugated board member due to the weight of the product is reduced, the safety at the time of transporting the product is improved, and the end surface of the corrugated board member is not torn or scratched, and a durable packaging material can be obtained.
