    Abstract: Plastic containers having improved physical properties are prepared from a composite billet having an outer peripheral area composed of a thermoplastic resin and an inner central core portion composed of the thermoplastic resin modified with a material which imparts improved physical properties such as reduced gas permeability or increased stiffness or rigidity to the resin. The composite billet is molded into a container wherein the billet core is formed into the sidewalls and bottom of the container and the peripheral portion is formed into a flexible thermoplastic flange surrounding the open end of the container which can be doubled seamed to a metal end closure without fracture.

    Abstract: This relates to an induction heating coil which is of a single turn construction and particularly configurated for inducing electrical energy into a metal foil barrier layer of a laminated container closure for effecting heat bonding of the closure to a container in a preselected seal pattern. The seal pattern contains either one corner or the closure is provided with a projecting pull tab wherein there is a greater heating requirement and thus a requirement for the induction of higher electrical energy into the closure. The need for the induction of a greater amount of heat into the closure at a corner or the location of a projecting pull tab is provided for by reducing the cross section of the heating coil at the location of the greater heat requirement. The reduction in cross section is primarily effected by forming a notch in the heating coil. If desired, a closer control of the heating effect of the coil may be obtained by positioning in the notch a ferrite insert.

    Abstract: This relates to an apparatus for heat bonding a lid having a metallic layer to a plastic container. The container, filled with a product, is seated in a nest and a lid is seated in place thereon. There is at least one corner on the lid and projecting from that corner is a pull tab. An induction heating unit is associated with the lid and presses it tightly against the container while inducing electrical energy under controlled conditions into the metal layer. The induction heating unit is provided with a specific arrangement of ferrite members for controlling the induction of current into the metallic layer. The ferrite parts in conjunction with the induction coil serve to concentrate the induced electrical energy into substantial alignment with the induction coil notwithstanding the fact that there is a corner and there is projecting from the corner of the lid a pull tab.
