A multilayered preform is disclosed for making an open mouth container. The preform has a container-forming portion comprising a circular central area for making the bottom of the container, an annular sidewall-forming portion for the container surrounding add integral with the outer periphery of the central area, a flange connected to the annular portion, said flange having the contour of the rim of the container, said container-forming portion having a predetermined volume to meet dimensional requirements, and a retaining member having an enlarged portion. The preform is an improved structure that is readily adaptable for making containers from the so-called solid state pressure forming process.
