[0001]

TECHNICAL FIELD The present invention relates to a packaging material for packaging an object to be packaged such as a gas water heater and a packaging structure using the packaging material.

[0002]

2. Description of the Related Art For example, when packaging an object to be packaged such as a gas water heater for transportation and storage, conventionally, a paper board-shaped material such as corrugated paper is used as a packaging material. A container (cardboard box) consisting of, or a pad (for example, a molded product formed by molding Styrofoam into a predetermined shape) for filling a gap between a predetermined part of the packaged object and the inner wall of the cardboard box is used. The pad functions to fix the packaged item in the cardboard box and to prevent the weight of the packaged item from being concentrated and added to the bottom of the cardboard box. It functions to protect the items to be packaged.

FIG. 8 is an exploded perspective view showing an example of a conventional packaging structure. In this packaging structure, both ends of the gas water heater A are held as a packaging material for packaging the object to be packaged (gas water heater) A, and the gas water heater A is protected from an external impact. A packaging material including a pair of cushioning pads 60a and 60b made of expanded polystyrene and a case body 61 made of corrugated cardboard for storing the gas water heater A whose both ends are held by the cushioning pads 60a and 60b. It is used.

The gas water heater A is packaged by closing the lid 61a and sealing the packaging case body 61 with a tape or the like.

However, in the above conventional packaging structure,
Buffer pad 60a made of resin such as styrofoam,
60b is used, and these members are
There is a problem that pollution (for example, generation of harmful gas) is likely to occur when it is treated as waste (for example, combustion treatment). Therefore, in order to reduce pollution problems and environmental problems, there is an increasing demand for reducing packaging materials such as resins.

In the conventional packaging structure, the packaging case body 61 made of corrugated cardboard, the two cushioning pads 60a and 60b made of expanded polystyrene, and the tray 6 are used.
In addition to the problem that the number of parts constituting the packaging material is increased and the cost is increased, it is necessary to manage a plurality of kinds of parts made of different materials. There is a problem that the burden becomes large.

The present invention has been made in view of the above background, and is composed of a single member, is easy to manage, and is economically reliable, and a packing material An object is to provide a packaging structure using a packaging material.
