ABSTRACT:
A flat container may be produced by extruding a molten resin to form a parison, closing the bottom of the parison, preblowing the parison such that the inner surfaces do not contact together, drafting the parison in a molten state, expanding the parison with the outer edge of the parison extending beyond that of the cavity of a mold, pinching the expanded parison with the mold to fuse the outer edge portions together along the outer edge of the cavity, and forcing a pressurized fluid into the parison pinched by the mold so that the parison is shaped in close contact with the inside surfaces of the mold cavity.
