PROBLEM TO BE SOLVED: To ensure gas barrier properties at a joint portion at ends of a film when a container is molded by disposing a film having gas barrier properties in a portion to be the container trunk portion, thereby obtaining a thin multilayer container having favorable barrier properties using a technique applicable to the molding of the thin multilayer container.SOLUTION: When molding a container by disposing in advance a film having gas barrier properties in a portion to be a container trunk portion, while a container surface resin is fed from an injection molding nozzle 9 into a container trunk-forming portion 12 of a mold 8, a gas barrier resin is fed in a belt shape into a position corresponding a joint 5 of a label film 4 as an intermediate layer between a portion of the container surface resin being spread along a core mold 10 and a portion of the container surface resin being spread along a cavity mold 11.SELECTED DRAWING: Figure 5 |
