Abstract
A can body has a curl portion to which a skirt portion of a cap is mounted. In the curl portion, an outer periphery upper-side bent portion that forms an outer peripheral portion of a folded-back top portion, an outer periphery-side tubular portion that extends downward in a can axis direction, an outer periphery lower-side bent portion that is bent inward in a radial direction, and a curl end portion that extends from an inner peripheral edge of the outer periphery lower-side bent portion are continuously formed. When a radius of curvature of an outer surface of the outer periphery upper-side bent portion is R(mm), a radius of curvature of an outer surface of the outer periphery lower-side bent portion is R(mm), and a radius of curvature of an outer surface of the inflection portion is R(mm), which is 0.05 to 0.2 mm, RRRis established.
