Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packing device for packing and storing heavy items such as outdoor units of separate air conditioners.

2. Description of the Related Art Structures of Conventional Examples and Their Problems Generally, among packaging devices used for packaging articles, resource-saving packaging devices are used in outdoor units of separate air conditioners and the like.

As shown in Figure 1, this packaging device consists of a bottom box (not shown) formed in the shape of a tray made of cardboard, and a cushioning material made of cardboard, wood, etc. Provide a lower cushioning material a,
The article b to be packed is placed on this lower cushioning material a, and furthermore, columns C ₁ , C ₂ , C ₃ , and C ₄ are erected at each corner of this lower cushioning material a to support the article during storage. Incorporate the accessory box d and cushioning material e that protect the appearance of b, cover with the upper cushioning material f made of cardboard tray-shaped like the lower cushioning material a, and bind and pack with a band g. It was hot.

However, with this type of packaging, when products are stacked for storage, the load of the products stacked on top is supported by supports C ₁ , C ₂ , C ₃ , and C ₄ erected at each corner of the packaging device. When storing products in a warehouse or the like, they are stacked with pallets h placed under them, as shown in Figure 2. At this time, as shown in Fig. 3, the column _C1 for supporting the load protrudes into the gap between the deck board i provided on the upper surface of the pallet h, and when the load is applied from the upper part, the lower cushioning material a In some cases, the bottom surface swelled as indicated by the wavy line a', causing the load to escape.
As a result, almost no load was applied to this column C ₁ , and all the load was applied to the opposite column C ₂ , which had the disadvantage that column C ₂ , on which the load was concentrated, could not withstand the load and broke. .

In addition, if the strength of the pillar itself is increased as a countermeasure, the cost will increase and the load will be unbalanced, resulting in extremely poor stability during storage. Furthermore, as the lower cushioning material a bulges as indicated by the wavy line a', the strength of the lower cushioning material a itself decreases, giving an uneasy appearance and resulting in poor protection and stability during storage and transportation. There was a drawback.

Purpose of the invention The present invention aims to eliminate such conventional drawbacks.
To provide a packaging device that has good stability during storage and strong protection strength.

Structure of the invention In order to achieve this object, the invention provides a reinforcing plate that receives the load of the support column within the bottom plate of the lower cushioning material.

With this configuration, deformation of the lower cushioning material can be prevented.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.
This will be explained with reference to the diagram.

In FIGS. 4 and 5, 1 is a tray-shaped bottom box made of cardboard;
The structure in which cushioning materials 2, 3, 4, and 5 made of cardboard, wood, etc. are adhered to the inside of the case is the same as that described in the conventional example. However, in the cushioning materials 2 and 3, the thickness t ₁ of the cushioning material 7, which is used for positioning when fixing the support column 6, is different from that of the other cushioning material 8.
The thickness is slightly thinner than the thickness t ₂ of the cushioning material 7 and the cushioning material 8, and between the stepped part of the cushioning material 7 and the cushioning material 8 and the bottom box 1, the same dimension l ₂ as the inner dimension l ₁ of the bottom box and the thickness of the cushioning material 7 and the cushioning material 8 are provided. A reinforcing material 9 with a thickness equal to the step of the wood 8 is glued on, and when the support post 6 is fixed during packaging, the support post 6 passes through the cut parts 2a and 3a of the cushioning materials 2 and 3 and is placed on top of this wood 9. I'm trying to get it posted. The reinforcing material 9 is not limited to wood, and may be a synthetic resin plate.

As shown in FIG. 5, the items to be packed are packed using the cushioning material provided in the above configuration and in the same packaging procedure as in the past, on pallets 10 during storage.
Even if the pillars 6 protrude from the gaps between the deck boards 11, the load will not escape due to the reinforcing material 9 laid inside the cushioning material, and the four pillars 6
Load is applied uniformly to the As a result, the load is not concentrated on only one side, and the support column 6 is less likely to break. In addition, since the stability when stacking is improved, the workability during cargo handling and storage is also improved, and the stored cargo looks orderly, giving a sense of security. Furthermore, since the strength of the cushioning material itself is increased, reliability of product protection against impacts during transportation is improved.

Effects of the Invention As is clear from the above embodiments, the present invention enables the pillars to be positioned and fixed at both ends of the short sides of the bottom plate, making it possible to provide a stronger packaging device with a simpler structure.

In addition, the load can be applied uniformly to the four pillars, and since the reinforcing material is sandwiched between the cushioning material and the bottom plate, the impact applied to the reinforcing material from the outside is buffered, preventing the pillars from breaking. In addition to improving the strength of the bottom plate, it improves the ability to protect items to be packaged, increasing stability during storage and transportation, and improving quality.
