<p><P>PROBLEM TO BE SOLVED: To provide a can body having a closed-end cylindrical shape, and to provide an inner surface coating method for uniformly coating the entire area of an inner surface of the can body with a paint. <P>SOLUTION: The can body 10 includes a bottom 11 formed of a dome portion 13 concaved to the inside of a can trunk 12, and an annular protrusion 14 extending from the dome portion 13 along its outer peripheral edge and protruding to the outside of the can trunk 12. The annular protrusion 14 has a nose 14a at the tip thereof, an inner peripheral wall 14b extending to the radial inside of the nose 14a, and an outer peripheral wall 14c extending to the radial outside of the nose 14a. Further the inner peripheral wall 14b extends via an annular concave portion 15 to the dome portion 13, and the outer peripheral wall 14c extends via an annular convex portion 16 to the can trunk 12. Herein an angleθwhich the inner peripheral wall 14b and a can axis form with each other is set to the range of not less than 8°to not more than 25°. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
