PROBLEM TO BE SOLVED: To provide a tubular metal container in which printing on the outer peripheral face of its barrel portion can be beautifully finished without deviating from the conventional processing and a coating film with a uniform thickness can be applied to its internal face stably. SOLUTION: A metal tube is formed so that at least the tubular barrel portion, a shoulder portion formed narrower than the barrel portion, and a discharging portion for contents are integrated. In this metal tube, the circumferential external face of a joint portion (a changing portion) between the barrel portion and the shoulder portion is bent at a specific angle. The circumferential internal face of the changing portion has R, which is preferably in the range of 0.5 to 2.0. COPYRIGHT: (C)2009,JPO&INPIT
