Abstract
A method for manufacturing a container having a tubular-shaped intermediate barrel portion that is covered with a flexible film. The tubular-shaped intermediate barrel portion is disposed on a mandrel that functions as a die core. The mandrel is installed with the tubular-shaped intermediate barrel portion to an upper die and a lower die. One end of the intermediate barrel portion covers the mandrel with flexible film. Molten polymer material is injected into the upper and lower dies, forming solid portions at opposite ends of the pipe-shaped barrel portion.
