    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.

    Abstract: This relates to a machine for assembling end units with container bodies. The container bodies have cylindrical open upper ends over which a cylindrical lower portion of an end unit or dome is telescoped with the overlapping portions being adhesively bonded together. The machine receives the end units serially and by way of a Ferris wheel type conveyor moves the end units first to an adhesive applicator where a band of adhesive is applied to the interior of each end unit, after which each end unit is then telescoped over and pressed into position relative to an associated body. The operation of the machine is continuous.
