ABSTRACT:
A container assembly is provided which comprises a composite tubular body having an outwardly rolled top rim which body has an asymmetrically tabbed membrane-type closure sealingly secured to the rolled rim so that the peripheral section of the closure conforms radially and circumferentially to an upwardly facing annular area of the rolled rim. The method of making the container subassembly comprises induction heat sealing membrane-type closure comprising an electrically conductive sheet to a composite tubular body comprising an electrically conductive liner with electrical insulation means and heat activatable sealant disposed therebetween. The method further comprises biasing the peripheral section of the closure towards the rolled rim with a uniformly distributed force while the induction heat sealing is being effected.
