摘要： A container having a novel flange configuration is disclosed that may be readily rolled with a closure to form an interlocking double seam to provide a leakproof container. The flange configuration may be readily interlocked due to its flexibility and resiliency with a closure without the flange being distorted, fractured or cracked. The container includes a peripheral flange connected to and surrounding the opening of the container, the flange having a channel adjacent the sidewall and a complementary bead associated therewith. In one embodiment, the container is made of a thermoplastic material comprising a plurality of superimposed layers, one of which is yieldable, so that when the flange is interfolded the yieldable material is forced outwardly to fill any that exist voids between the flange and closure to form a complete and flexible seal.

摘要： 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.
