BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extrusion-molded plate edge component (hereinafter referred to as "extrusion-molded plate edge component" used for an extrusion-molded plate having a front plate, a back plate and a core and having a ladder-shaped cross section, which is formed by extrusion molding. Edge part ") and an assembly for an extruded plate.

[0002]

2. Description of the Related Art For example, when a plastic corrugated cardboard product such as a box is made of a plastic corrugated cardboard which is a kind of extruded plate, when the plastic corrugated cardboard is thin and excellent in flexibility, the connecting portions are connected to each other. It was usual to provide a flap so that it would not come to the corner of, and use this flap to make a plastic cardboard product. In this case, in order to connect the plastic cardboards to each other, a U-shaped or comb-shaped connecting member is simultaneously inserted into the hollow part of the plastic cardboard to be connected, or a clip-type connecting member is used to overlap the plastic cardboards. The cardboards were sandwiched between plastic cardboards. Further, the end portion of the plastic corrugated board is simply covered with a long clip-type cover component having a U-shaped cross section.

[0003]

However, when the plastic corrugated board is thick and the plastic corrugated board is not flexible, it is difficult to make the flap by folding, and the plastic corrugated board at the corners and the like. It becomes necessary to connect the ends of the two in a state of abutting each other. In this case, if the U-shaped or comb-teeth shaped connecting member is used for connection, a gap may occur between the ends of the plastic corrugated board, which is not preferable. Further, when a force opposite to the inserting direction is applied to the U-shaped or comb-shaped connecting member, there is a problem that the connecting member is easily removed. Such a problem also occurs when using a clip-type connecting member or a cover part. Further, since the end face of the plastic cardboard in the extrusion direction has a ladder shape and a large number of holes are exposed, it has a bad appearance and is apt to be chipped or deformed.
Similarly, the end face of the plastic corrugated board that is orthogonal to the extrusion direction also has a poor appearance and is easily chipped or deformed.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an edge part which is difficult to remove after once attached to an extrusion plate, and an extrusion plate assembly using this edge part. There is.
