(57) [Summary] [Structure] In this sealing method, a lid having an engaging space outside the outer periphery of the curl portion is attached to the mouth of a container having an outer curl portion at the open end, and the curl is formed.

[Effect] Even for thin containers such as seamless cans that do not have high strength against axial load, easily and securely attach the lid and perform good sealing without deforming the body or bottom.
