ABSTRACT:
A composite container including a peelable patch top closure assembly, and a method for forming the same, are disclosed, including a tubular composite body member reversely outwardly curled at one end, a generally disk-shaped membrane patch top member extending across the reversely curled body end to close the same, and a heat sealable coextrudable synthetic plastic film laminate bonding the patch top member to the reversely curled body end, the coefficient of adhesion between the laminate layers being less than that between the laminate layers and the adjacent surfaces of the associated members, respectively.
