Abstract
A portable, durable, lightweight cooler system designed to maintain beverages, food, medical supplies, drugs, and other heat sensitive products at existing temperatures with substantially reduced heat gain or loss from the surrounding environment for extended periods of time, when no power source is available. This container is designed to greatly reduce radiant heat transfer along with conductive and convective heat transfer while diminishing decomposition effects of stored items and thus maintaining freshness. This system includes a cooler housing, a reinforced lid, a radiation reflective material application, and a system to remove air from the containment area, thus creating a vacuum within the cooler itself and sealing the lid to the cooler housing. Upon actuation of a vacuum release device, air is reintroduced into the containment area thus allowing the lid to be removed and the stored products be accessed.
