WIPO Patent Application WO/2000/032288

Kind Code:

A1

Abstract:

A method of molding doll heads faithfully to a mold by blow molding using a safe molding material, and a mold therefor. A split mold (2, 3) formed with an inner surface shape conforming to the shape of a doll head (17) is used such that a parting line (18) resulting from the split mold (2, 3) is positioned at or in the vicinity of the hairline of the doll head (17). The molding material, which contains synthetic resin thermoplastic elastomer used as the main ingredient, with a plasticizer and a coloring agent added thereto, is heated and the parison (15) is fed into between the split mold halves (2, 3) disposed apart from each other, whereupon the split mold halves (2, 3) are closed and air is blown therein. When air is blown into the split mold (2, 3), the air in the cavity is removed through at least one place on a protruding portion such as the nose (5).
