2. Description of the Related Art Generally, when packing various devices such as electric products, the cardboard box together with a cushioning material is used for the purpose of preventing the device from moving inside the cardboard box and protecting it from external impact. It is housed in a car to protect the equipment during transportation and storage.

As a conventional cushioning material, a material formed by molding a foamed plastic such as styrene foam is widely used. Foamed plastic is a material having an excellent cushioning function for protecting equipment, and can be easily molded in accordance with the shape of various equipment, and has an advantage that storage efficiency in packaging materials can be increased.

[0004]

However, although foamed plastics have extremely excellent properties themselves, they have various problems in terms of processing after recently used as a cushioning material. For example, the collection route has not been developed, so it is thrown away as household waste, which is a big social problem. Along with this, it takes a lot of time to handle at the time of collection and the collection cost becomes high. Moreover, since high energy is required for incineration and disposal, it is necessary to install an incinerator. In addition, since the cushioning material made of foamed plastic itself is extremely bulky, there are drawbacks in that the transportation efficiency is low, the transportation cost is high, and a large space is required for the storage space. For this reason, in the industry, a cushioning material having an excellent cushioning function and a simple structure has been widely demanded as a substitute for the foamed plastic.

[0005]

Therefore, the present inventor has achieved the present invention as a result of intensive research in view of the above points, and is characterized in that one surface of a container is fitted. In a corrugated cardboard cushion in the shape of a tray container having an open upper surface, a peripheral wall formed in a rectangular tube shape having an internal space is arranged around a bottom plate, and the bottom is provided at four corners inside the peripheral wall. The triangular columnar member formed by bending the cut piece provided on the face plate is arranged.

The term "is a shape in which a top surface having side surfaces arranged around a rectangular bottom surface is opened, and one surface of the container is fitted into the inside to protect the container. Examples of the container include products and parts such as the microwave oven and the amplifier described above. What is one side of the container?
These are the side surface, front-rear surface, top surface, bottom surface, etc. of the storage body. For example, when attached to the side surface of the storage body, two left and right are usually used as a set.

The "peripheral wall" refers to one that forms a peripheral surface by being arranged around the bottom plate. In the present invention,
The peripheral wall is formed into a rectangular tube shape having a space inside. As a means for forming the peripheral wall into a rectangular tube shape, for example, the peripheral wall forming piece is extended from the bottom plate and bent. In this case, the peripheral wall forming piece alone may be formed into a square tube shape, or a part of the bottom plate may be used to form a square tube shape.
Further, a separate peripheral wall forming body may be attached to the inside of the side plate of the tray container body to form the peripheral wall. As a separate peripheral wall forming body, in addition to corrugated cardboard made into a corrugated cylinder or bent into a square tube, mount it with a U-shaped bent with the opening facing the bottom plate or side plate. You can use the one The point is that it may have a rectangular tubular shape when the peripheral wall forming piece is bent or when a separate peripheral wall forming body is attached to the tray container body.

The "triangular columnar member" is a member formed in the shape of a triangular column and arranged at four corners inside the peripheral wall. In the present invention, the triangular columnar member is formed by bending a cut piece formed by cutting a bottom plate. The inner wall surface of the peripheral wall may be used as the portion facing the peripheral wall of the triangular columnar member. In this case, it is preferable that the top plate of the triangular columnar member is held by a method such as providing an insertion hole on the inner wall surface of the peripheral wall and inserting the insertion piece into the insertion hole.
