The method for manufacturing this molded paper body is to draw-process, with a punch and die, a single blank primarily of paper, and is characterized by use of a holding mechanism to press the outer peripheral portion of the blank between a wrinkle pressing member and the die upper surface, and setting the force applied by the wrinkle pressing member within an appropriate range.Type: ApplicationFiled: October 2, 2012Publication date: September 11, 2014Applicants: TOYO SEIKAN GROUP HOLDINGS, LTD., TOKAN KOGYO CO., LTD.Inventors: Ichiro Kunihiro, Seiji Okabe
