摘要

Packaging apparatus for packaging a product in a container comprising a semi-rigid cup having an open mouth and a flange projecting outwardly from this mouth and a top sealed to the flange around the periphery of the cup. The apparatus includes heat-sealing elements formed of resilient heat-conducting material, adapted to make high-quality, uniform heat seals at high speed to container sealing surfaces having irregular contours.
