Abstract
A thermally insulated bottle has a container body which includes an inner body capable of holding a liquid contents, an outer cup of semi-rigid semi-flexible construction surrounding and spaced radially outward of the inner body, and a barrier layer disposed between the inner body and the outer cup. The outer cup has a construction capable of providing a moisture barrier and sufficient to provide mechanical strength capable of supporting the inner body in an upright relation. 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. The insulated bottle also includes a closure cap which fits over and is releasably sealable with an open top of the container body.
