The invention provides a molding method for a container made of resin, and the method can enable the manufacture cost to be reduced through preventing the eccentricity of opening parts. A pre-molded base (20) with two opening parts (21, 22) is put in a blow molding die (3), thereby enabling the second opening part (22) to be located at the front of the forwarding direction of a telescoping rod (2) entering through the first opening part (21). When the telescoping rod (2) enters into the pre-molded base (20) through the first opening part (21), blow molding air (50) is blown in, thereby enabling the main body (23) of the pre-molded base (20) to carry out the 2-axis extension. When a molded body (32) formed through the 2-axis extension contacts with the blow molding die (3), the root part (32a) of the second opening part (22) is cooled at a temperature lower than that of other parts, thereby preventing the eccentricity of the second opening part (22). |
