METALLIC EXTRUDED TUBE, AEROSOL CAN AND METHOD OF MANUFACTURING METALLIC EXTRUDED TUBE

摘要

A collapsible metal tube, comprising: a metal body portion susceptible of plastic deformation, said body portion being sealed at one end; a shoulder portion and a mouth/neck portion connected to the other end of said body portion; and a resin film provided on the inside wall surface of the body portion, said resin film comprising a metal-adhesive thermoplastic resin layer formed by spray-coating the inside wall surface of the body portion with a dispersion of fine spherical particles consisting or a metal-adhesive thermoplastic resin and then heating to integrate said particles. The resin film formed on the inside of the collapsible metal tube is reliable because it is a dense resin film virtually devoid of pinholes, excellent in elongation at break, and free from cracking when folded or deformed, and is excellent in ability of protecting the metal body portion and the contents.
