Document Type and Number:
WIPO Patent Application WO/2005/014198
Kind Code:
A1
Abstract:
A bulge can (1) manufactured by bulging a sealed can with an internal pressure by air blow to provide a large bulging rate without lowering the mechanical strength of a material, i.e., without annealing, and allowed to increase quality, productivity, and economic efficiency, a method of manufacturing the bulge can, and an apparatus of manufacturing the bulge can. The bulging rate of a bulged part (13) is set to 15% or less. On the plate thickness of the bulged part (13), a plate thickness reduction rate &agr = (Tb - Ta) × 100/Tb (where Tb is a plate thickness (mm) before bulging and Ta is a plate thickness (mm) after bulging) is set to 6% or less.
