The inner body can be a cup similar to the outer cup, or a flexible bladder. The barrier layer can be a reflective metallic foil layer, or a substrate having a metallic material defining a mirrored surface thereon capable of reflecting radiant electromagnetic energy back toward the source thereof so as to reduce the transfer of such radiant energy across the barrier layer.
