Abstract

PURPOSE: To obtain the back sheet, the cover etc. of a container, by lapping the waste material which has holes at four corners and the framewise and crosswise tearing means connecting each hole, the face material and the back material, welding their peripheries, then tearing the waste material by the tearing means, reversing it to overlap the back material and welding them.
CONSTITUTION: The waste material 1 is formed in a rectangular form using thermoplastic resin and provided with circular holes 5 on its four corners, the framewise made tearing means 6 connecting each hole 5 and the crosswise made tearing means 7 connecting holes at diagonal positions. The back material 4, the core material 3, the face material 2 and the waste material 1 are successively lapped upward and are set into the mold and heat-pressing or high frequency welding is done from the upper face periphery of the waste material 1, thus the periphery is fusion-bonded. Then, the tearing means 7 are cut off and the waste material 1 is reversed to lap the back material 4 and fusion-bonded. By this way, the back sheet and the cover having the periphery of the pretty and decorative edge can be obtained.
