PURPOSE:To form a confluent line in a straight line to improve the appearance by a method wherein a space for a resin tab is formed at a top end of a two color resin confluent position in a mold cavity for a two-color container, and the resin tab is cut after the two-color container is molded. CONSTITUTION:A space for forming a resin tab 30a is provided at a top end of a part corresponding to a flange 20 in a mold cavity corresponding to the shape of a two-color container, i.e., a top end 40a of a two color resin confluent position. By forming a two color confluent line L of the flange part 20 of the container in this manner, the internal pressure of the cavity never rapidly increases at the end part of the resin confluent position, and the confluent line L is not disturbed but formed in a straight line. After the molded article is removed from the mold, the resin tab 30a is cut. In this manner, the straight confluent line L improves the appearance. |
