Japanese Patent JP7133586

B2

To be able to fix a skirt part of a cap by surely winding it, and to reduce discomfort at lips during drinking.SOLUTION: A can body includes a cylindrical part, a neck part whose diameter is smaller than the cylindrical part, and a mouth part connected to the neck part. At an outer peripheral part of the mouth part, a curl part is provided in which an end part including an edge is folded radially outward and wound. The curl part has an outer diameter of 31 to 35 mm inclusive, and is formed continuously, on a vertical cross section passing a can axis, with: an outer peripheral upper side bent part for forming an outer peripheral part of a folding apex part; an outer peripheral side cylindrical part extending downward in the can axis direction from a lower end of the outer peripheral upper side bent part; an outer peripheral lower side bent part bending radially inward from a lower end of the outer peripheral side cylindrical part, and forming a convex shape obliquely downward of the can axis direction; and a curl end part extending while reducing its diameter radially inward via an inflection part from an inner peripheral edge of the outer peripheral lower side bent part and including the edge. When curvature radii of the outside surface are defined to be R5 (mm) at the outer peripheral upper side bent part, R6 (mm) at the outer peripheral lower side bent part, and R7 (mm) at the inflection part, a dimensional relation among the radii is R7
