Abstract

A three-piece resealable can for acidic liquid includes, a cylindrical can body member that includes a screw portion at one end; and a can bottom member that contacts the can body member so as to close an opening portion of the other end of the can body member. The can body member includes a cylindrical first steel sheet, Ni plating that is formed on an inner circumferential surface of the first steel sheet, a polyester film that is formed so as to be disposed on the outermost surface of the inner circumference of the can body member, and a Zr-containing film that is formed between the first steel sheet and the polyester film. The can bottom member includes a second steel sheet, and Sn plating that is formed on the can body member side of the can bottom member. The Zr-containing film contains Zr compounds.
