属管を大量生産することは非常に困難であつた。 BACKGROUND ART Until now, it has been known to glue a plastic sheet printed with a wood grain pattern, a floral pattern, etc. onto the surface of a metal plate to make a decorative board. However, when a plastic tube is attached to a metal tube and a decorative metal tube is manufactured, when the temperature rises, the tube tends to expand outward and the plastic tube falls off. It was thought that it could not be manufactured. For this reason,
Decorative metal tubes are manufactured by plating or painting, and it has been extremely difficult to mass-produce metal tubes with complicated patterns such as wood grain patterns and floral patterns.

本発明をなすに至つた。 The present inventor, in order to develop a simple method of manufacturing a decorative metal tube by covering it with a plastic tube with a printed pattern, similar to the above-mentioned decorative board,
As a result of extensive research, we have found that in addition to bonding a heat-shrinkable plastic tube to a metal tube through a hot melt adhesive layer, and in addition to heat treatment to shrink the plastic tube during the bonding process, we have also applied a separate process to the metal tube. The inventors also discovered that a decorative metal tube with a firmly attached covering tube can be obtained by subjecting it to rapid heating treatment, and based on this knowledge, the present invention was accomplished.

ある。 That is, in the present invention, a heat-shrinkable cosmetic plastic tube having a hot melt adhesive layer on the inner surface is attached to the surface of a metal tube, and then the plastic tube is heated by hot air from the outside to 100 to 200°C to shrink the plastic tube. is brought into close contact with the surface of the metal tube, and then the metal tube itself is heated directly to a temperature within the range of 150 to 250℃ and higher than the shrinkage temperature using a high-frequency induction heating method to melt the adhesive and form a plastic tube. The present invention provides a method for manufacturing a decorative metal tube, which is characterized by bonding the decorative metal tube with a metal tube.

By rapid heating to a temperature range of ~250℃,
The hot melt adhesive can be activated to develop sufficient adhesive strength without deteriorating the coated decorative tube, and on the other hand, the shrinkage of the thermally expanded metal tube can be accommodated and the adhesive can be firmly bonded. If the rapid heating temperature is less than 150°C, a firm attachment cannot be achieved, while if it exceeds 250°C, the coated cosmetic tube will deteriorate.
