ABSTRACT:
A heat seal carrier assembly is provided for mating a covering material with a deformable sealing portion of a product-filled container to seal the container. The carrier assembly has an upstanding wall including a top surface having a raised ridge thereon. The container is situated on the carrier assembly to properly align the container sealing portion with the top surface of the upstanding wall of the carrier assembly. A heat seal head moves downwardly to press the covering material and the sealing portion of the container against the raised ridge and the top surface of the upstanding wall of the carrier assembly to seal the covering material and the sealing portion of the container together.
