Patent attributes
An insulated bag has generally flat top and bottom walls connected by foldable back and opposite side walls which cooperate to define a chamber having a front opening for receiving a food product. Flexible closure flaps extend from the bottom wall and opposite side walls and have releasable fasteners for closing the front opening. Each wall has an outer fabric covering and a porous inner liner and also inner and outer layers of flexible thermal insulation material. A vapor barrier film separates the inner and outer layers of insulation material in each wall and provides for moisture absorption by the inner layers. The top and bottom walls each have a compartment with an edge opening closed by a releasable fastener, and a vacuum insulation panel is confined within each compartment. The top and bottom walls move between a collapsed storage position and an expanded position to receive the product.
