Zusammenfassung:	PROBLEM TO BE SOLVED: To excellently curl a mouth molding section so as to prevent a mouth cut section from coming into contact with lips by using a general curling device for a molding container formed from a foamed resin sheet having excellent property as a foamed container. SOLUTION: After a foamed resin sheet is heated and molded so as to form a container body 2 and a mouth molding section 3 extended outward around an opening 5 of the container body 2 is formed, a foamed container 1 is taken out being punched and cut with an extracting blade from the foamed resin sheet excepting the mouth molding section 3. When the mouth molding section 3 is to be curled by a roll 11 having a groove for curling, hot blast is applied to the surface of a part to be folded in by the curling of the mouth molding section (hot blast irradiation section 11).
