Abstract
PURPOSE: To mold the container with double wall structure made of synthetic resin of which an outer container is well molded by a method wherein a core is mounted into the neck part of an inner container and, after they are entered into the mold, a resin is injected between the inner container and the mold to mold an outer container.
CONSTITUTION: In carrying out the injection molding of the container with double wall structure made of the synthetic resin having a neck part 5a of which inner diameter is smaller than that of a barrel part 5, the neck part 5a of a molded container (an inner container) 5 made of a synthetic resin molded by appropriate means so as to form the neck part 5a of which an inner diameter is smaller than that of a barrel part is held between a core 2 and a splittable mold 1 and, after the mold is closed, a desired synthetic resin material is injected into a molding space 6 between the molded container 5 and the splittable mold while a cooling fluid is supplied into the molded container 5 under a predetermined pressure and recirculated therein.
