    • PROBLEM TO BE SOLVED: To prevent the internal surface of a metal tube from being corroded, and easily discharge a gas generated from a content to the outside by a method wherein on the internal surface of the metal tube in the vicinity of the bottom part, a sealing compound for the doubly seamed part is lined, or a sealing film is bonded. SOLUTION: On the internal surface alone of a bottom part 3, a lining treatment with a sealing compound 4 is applied, and the bottom part 3 is doubly seamed. For the raw material, a polyethylene based elastomer, etc., are generally known. Instead, when a sealing film is bonded, for the film, polyolefin based film is suitable, and other synthetic resin films being excellent in gas permeability can be used. On the internal surface of a metal tube main body 1, a polyamide-imide resin is applied. By this method, the main body is prevented from being corroded by a content of which the major component is hydrogen peroxide, and also, oxygen which generates by decomposing the content can be efficiently discharged to the outside from the doubly seamed part 3.
