BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging material for a bumper made of an automobile synthetic resin such as polyurethane.

[0002]

2. Description of the Related Art Conventionally, a synthetic resin bumper of an automobile is easily stored in a corrugated paper box because it is easily deformed. However, since the bumper is formed with a sleeve that bends backward, there is a disadvantage that the remaining space in the box is large and the entire box becomes unnecessarily large. Further, there is a disadvantage that the bumper moves and deforms in the box.

On the other hand, Japanese Utility Model Application Laid-Open No. Sho 59-162482 discloses a packaging insert comprising a square tubular torso insert and sleeve inserts inserted and connected to both ends of the torso insert. . The above insert is inserted along the back surface of the bumper. However, since the square tubular torso insert is integral, it usually does not fit into the rear surface of the bumper bent at the center. In addition, the protrusion from the rear surface of the bumper is angular and large, so that when the whole is wrapped with wrapping paper, it is difficult to wrap. In addition, the sleeve insert requires an assembling process with two members, which increases the cost.

[0004] In addition, since the package of a vehicle bumper disclosed in Japanese Utility Model Laid-Open Publication No. 2-48516 is placed from above to below, it is difficult to handle a long bumper because it becomes long.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automobile synthetic resin bumper wrapping material which has sufficient strength, is easily adapted to a bumper shape, has a small protrusion at the time of insertion, and is easy to handle. Is to do.

[0007]

[0008]

In the above-described automobile synthetic resin bumper wrapping material, the folded sleeves of the first and second pieces are bent, and the locking pieces are inserted into the locked holes to form a triangular cylindrical shape. After the formation, the projection for insertion is inserted into the recess for insertion to connect them.

Then, after the connected first and second pieces are inserted along the rear surface of the bumper, the whole is wrapped with wrapping paper, and a plurality of locations are wound and fixed with adhesive tape to finish.

Since this packaging material has a triangular cylindrical shape, it has high bending and torsional strength and effectively protects the bumper.

Further, since the first and second pieces are connected, the connecting portion has a slight degree of freedom in the bending direction, so that it is easy to adapt to the shape of the back surface of the bumper.

Further, since the protrusion from the rear surface of the bumper is triangular cylindrical, the protrusion is small, the packaging paper can be saved, and the storage cost can be reduced.

Further, since the locking piece is inserted into the locked hole and fastened, no adhesive tape or the like is required, and the assembling workability is good.
