Title:
METHOD FOR MANUFACTURING METAL CONTAINER, APPARATUS FOR MANUFACTURING METAL CONTAINER, AND METAL CONTAINER
Document Type and Number:
WIPO Patent Application WO/2022/065003
Kind Code:
A1
Abstract:
This method for manufacturing a metal container comprises: a first step in which a metal plate is shaped so as to form a substantially planar four-sided bag (B); a second step in which one surface and the other surface of the four-sided bag (B) formed in the first step are clamped by first and second parallel plate jigs (11, 12); and a third step in which the interior of the four-sided bag (B) is pressurized and the volumetric space inside the four-sided bag (B) increases as the distance between the first and second parallel plate jigs (11, 12) increases, while maintaining the state of contact between the first and second parallel plate jigs (11, 12) and the four-sided bag (B) clamped by the first and second parallel plate jigs (11, 12) in the second step.
