ABSTRACT:
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.
