Abstract:
PROBLEM TO BE SOLVED: To divert a transfer means based on a vacuum and pressurized air ejection mechanism which is generally used in a conventional two-piece can without considerably modification in manufacturing a bottle-shaped can that a neck portion and a shoulder portion are formed on a bottom side of a bottomed can and a printed design is applied on an outer surface of a body portion thereof. SOLUTION: A bottle-shaped can manufacturing method comprises a process in which a thermoplastic film layer is formed on both sides of a metal sheet, and the coated metal sheet with a lubricant applied thereto is punched to form a cup, a process in which a body portion of a cup-shaped body is further reduced in diameter to form a thin-walled bottomed cylindrical can, and a process in which the bottom side of the bottomed cylindrical can is formed into the shoulder portion and the non-opened neck portion, so that a process in which the printed design is applied on an outer surface of the body portion of the can formed into a bottle shape so that the neck portion is non-opened and an end of the body portion is opened is performed after a process in which the lubricant is removed from at least the outer surface of the can and before a process the non-opened neck portion is opened to form a curled portion and a threaded portion.
