Abstract
In an embodiment, an injection stretch blow molding device includes an injection molding section that produces N (N is an integer equal to or larger 2) preforms by injection molding, a cooling section that subjects the N preforms transferred from the injection molding section to forced cooling, a heating section that continuously transfers and heats the N cooled preforms, and a blow molding section that subjects the N heated preforms to stretch blow molding in n (n is an integer equal to or larger than 2) operations, the blow molding section simultaneously stretch blow molding M (M=N/n, M is a natural number) preforms among the N preforms into M containers.
