摘要： PURPOSE:To ornament an Al sheet having a PVC sheet stuck with an adhesive by working the Al sheet to a desired shape, partially cutting off the PVC sheet to expose the Al surface, anodically oxidizing the exposed Al surface and carrying out pore sealing treatment. CONSTITUTION:A chemically treated layer 2 and an adhesive layer 3 are successively formed on the surface of an Al sheet 1 and a PVC sheet 4 is stuck to the Al sheet 1 by a roll pressing method. The Al sheet 1 having the PVC sheet 4 is drawn and the ear of the drawn body is cut off to form a cap 5. Two circular grooves 6 are cut in the outside of the cap 5 with a diamond bit to partially expose the Al surface. The cap 5 is then immersed in an aq. solfuric acid soln., where an anodic oxide film 7 is formed by conventional anodic oxidation. The cap 5 is further immersed in a dye soln. and the film 7 is treated to seal the pores.

摘要： PURPOSE:To form a cap body which is not peeled off easily even if it is subjected to alcoholic contents or a thermal effect, by drawing a plate-shaped material of Al to which a vinyl chloride sheet has been stuck, and bringing it to a heating treatment by the specified temperature and time. CONSTITUTION:A plate-shaped material is made by constituting a chemical conversion treatment layer 2 on the surface of an Al plate 1, also interposing an adhesive material layer 3 and sticking a vinyl chloride sheet 4. This plate- shaped material is formed by a press to a cap shape by setting a drawing depth ratio to >=1.0, it is brought to a heating treatment at a temperature of 60 deg.C-80 deg.C for >=3min, and thereafter, a lug part 5 which is generated by a directional property of an Al material is cut and removed, and a cap body 6 is formed. In this way, the cap body 6 which is not peeled off easily is formed by executing a heating treatment after the press forming, and eliminating a stress for peeling-off, which remains on the vinyl chloride sheet 4.
