DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging cushion member and a method of manufacturing the same, and a packaging cushion and a method of assembling the same. More particularly, the present invention has a remarkable effect in reducing the amount of conventional cushioning materials such as styrene foam. It relates to what to play and how.

[0002]

2. Description of the Related Art Conventionally, a large amount of styrofoam has been used for packing home electric appliances such as an electric washing machine, an electric refrigerator and an air conditioner in order to prevent the product from being damaged during transportation.
In addition, Styrofoam is easy to mold and process and has excellent cushioning properties, so it is also commonly used for applications such as fish boxes, parts packaging, fruit packaging, and optical machine packaging. I am following.

[0003] However, the styrofoam after use is bulky and difficult to treat, and is ultimately almost incinerated in an incinerator. At this time, a large amount of heat is generated, and if the combustion conditions are poor, black smoke is generated. This has been a problem in environmental measures in combination with the lack of capacity of incineration facilities in each municipality.

[0004] In view of environmental measures, major electric manufacturers and the like who use a large amount of styrofoam are trying to reduce the amount of styrofoam by recycling used paper or using alternative materials such as paper and pulp such as corrugated cardboard. It is still a stage of exploration because it is disadvantageous in terms of cost,
The fact is that the effect is not so high.

[0005] In view of these points, the inventor of the present invention, in order to reduce the number of styrofoams, firstly attach at least two layers of corrugated paper or the like to a prefabricated cushioning material that is applied to the four corners of a packaged body (generally a rectangular parallelepiped). We believe that it should be made using the above materials, and that it should be able to be used repeatedly to save resources and prevent pollution. Filed.

However, the triangular pyramid-shaped packaging buffer is a rectangular parallelepiped 8.
It is extremely effective when supporting two ayas (corners) individually. However, thin types such as amplifiers, tuners, VTRs, thin air conditioner indoor / outdoor units, CD players, notebook word processors, personal computers, small LCD televisions, etc. It has been found that the use of eight triangular pyramid-shaped packaging cushions, as in a general rectangular parallelepiped, is extremely impractical in terms of work efficiency in order to provide good support for the product at its four corners.

Therefore, in the case of these thin products, it is desirable to support the packaging with four packaging cushions, and it is necessary to devise a packaging cushion having a shape suitable for the packaging cushion (see FIG. 13).
Therefore, as a result of further research, the present inventors have arrived at the present invention relating to a hollow triangular prism-shaped packaging buffer, a material thereof, and a method of manufacturing and assembling the same using a material such as corrugated paper.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the amount of styrofoam or the like used as a buffer, save resources, and facilitate processing after use to prevent pollution.

It is another object of the present invention to provide a reusable prefabricated packaging cushion or equivalent.

It is still another object of the present invention to provide a method of manufacturing an assembling type packaging buffer or a member which can be handled as a compact plate-like member having an extremely high space factor during storage and transportation.

Still another object of the present invention is to efficiently support a thin product at four corners with high efficiency.
