Can body

A can body comprising:

• a body portion that has a cylindrical shape;
• a neck portion having a smaller diameter than the body portion;
• and
• a mouth portion connected to the neck portion, wherein an outer peripheral portion of the mouth portion has a curl portion in which a tip portion thereof is folded back outward in a radial direction,
• in the curl portion, in a longitudinal cross section passing through a can axis, 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 from a lower end of the outer periphery upper-side bent portion, an outer periphery lower-side bent portion that is bent inward in the radial direction from a lower end of the outer periphery-side tubular portion through an inflection portion, and a curl end portion that extends from an inner peripheral edge of the outer periphery lower-side bent portion while reducing a diameter toward an inner side in the radial direction are continuously formed,
• the inflection portion is disposed on the outermost side of the curl portion in the radial direction and is formed as a linear shape along a circumferential direction,
• when a radius of curvature of an outer surface of the outer periphery upper-side bent portion is R5 (mm), a radius of curvature of an outer surface of the outer periphery lower-side bent portion is R6 (mm), and a radius of curvature of an outer surface of the inflection portion is R7 (mm), a relationship of R7<R6<R5 is established, and
• the radius of curvature R7 of the outer surface of the inflection portion is 0.05 mm or more and 0.2 mm or less.
