2. Description of the Related Art Conventionally, as a cushioning material capable of accommodating and packaging the above-mentioned plate-like bodies one by one in a groove, there has been disclosed in Japanese Patent Laid-Open No. 5-319456. There was something. However, the individual cushioning materials described in the above publications are L-shaped, and the pressure from the outside tends to be concentrated on the corners and is easily applied to the corners so that they spread outward or bend inwardly, resulting in a plasma. Display (PD
In some cases, the strength of a large-sized plate-shaped body such as P) is insufficient for packaging, and independence is poor and unstable, which tends to cause instability in packaging work. Further, since the packaging form for integrating with a pallet or the like is not taken into consideration, it becomes very unstable when the plate-shaped body is stored with the cushioning material placed on the pallet. In particular, when the plate-like body is a large heavy product such as a plasma display, there remains a problem in terms of stability.

Next, there is a transport box with a groove into which a plate-shaped glass component is inserted, which is described in Japanese Patent Application Laid-Open No. 8-301354. However, since the carrier box described in the above publication is composed of a container body and a lid, the amount of resin for molding the carrier box is large, and the size of the plate-shaped glass parts is limited. There is a problem that there is no freedom for. Therefore, in the present invention, a cushioning material that can maintain stable strength, is suitable for protecting the plate-like body from vibrations during transportation, etc., and is easy to adapt to different sizes of the plate-like body, and uses the same. The present invention was invented for the purpose of providing a package.

If the convex portion and the other concave portion for fitting are arranged and formed so as to be fitted to each other, it is possible to store a plate-shaped body such as a plasma display in a state in which both cushioning members form a row. It is excellent in stability and strength due to its self-supporting property, and is suitable for protecting a large number of plate-shaped bodies.

Further, regarding the fitting convex portion and the fitting concave portion,
As described in claim 4, when the fitting convex portion and the fitting concave portion are formed so as to be vertically slidable for fitting, the upper side is opened. When the cushioning material is set in the exterior body from above, the two cushioning materials can be connected by sliding in the vertical direction, which makes the setting extremely easy. Further, the connection strength between the two cushioning materials is increased.

According to a fifth aspect of the present invention, the outer surface serving as the bottom surface of the horizontal plate is provided with a convex portion for fitting with a pallet. Since it can be set in a connected state with the pallet,
The stability is improved, and it is convenient that the pallet can be moved. According to a sixth aspect of the present invention, a combination of the cushioning material according to any one of claims 1 to 5 and a plate-shaped cushioning material having a plurality of plate-shaped body supporting grooves formed on its surface is used. Then, the cushioning material can be used in various combinations due to the diversification of the use place by the plate-shaped cushioning material.

Further, as in claim 7, claims 1 to 6
Characterized in that it includes a cushioning material according to any one of (1) to (5) and a pallet, the connection between the pallet and the cushioning material (which may include a plate-shaped cushioning material) is strengthened, and a more diverse cushioning material is used. You will be able to exert the effect.
