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.

1. A vacuum based cooler that substantially decreases the amount of heat transfer between that of the contained products and that of the outside environment by means of vacuum and radiation reflecting material while maintaining a durable, light weight, and portable housing to be used for extended periods of time when no power source is available, the cooler comprising: a) a durable impact resisting cooler assembly for containment of objects said cooler assembly having a perforated interior shell consisting of a bottom and side walls and a durable impact resisting exterior non perforated shell consisting of side handles, bottom, side, and top walls which define an opening;b) a durable impact resistant lid assembly composed of a hollow reinforced shell consisting of a bottom wall, top wall, and at least one side wall, containing a continuous radiation reflecting material along an interior face of the bottom wall and the side wall of said hollow reinforced shell spanning the distance of said opening that will close said opening and come to rest on a seal set upon said perforated interior shell side walls, hence sealing the interior shell of the cooler assembly from the outside environment, the bottom wall of said hollow reinforced shell being perforated such that air may transfer from the interior of said lid to the interior of the cooler assembly, an exterior surface of said lid assembly is shaped for hand gripping or mounted with lid handles;c) a continuous radiation reflecting material laminated on an exterior face of both bottom and side walls of said interior shell that will reflect thermal energy transferred via radiation away from said interior shell and thus products stored within the interior shell;d) a vacuum pump assembly located between said interior and exterior shells for the removal of air within the cooler assembly to create a vacuum within both the cooler assembly and the lid assembly for the pressure scaling of said lid assembly to the cooler assembly and to limit conductive and convective heat transfer between that of the exterior non perforated shell, the exterior surface of said lid assembly and that of said interior shell and thus products stored within the interior shell;e) a vacuum release assembly located between said interior and exterior shells for the reintroduction of air into said cooler and lid assemblies, thus breaking the pressure seal between said cooler and said lid assemblies allowing for lid assembly removal from the cooler assembly via lid gripping features. 2. The vacuum based cooler as claimed in claim 1, wherein the vacuum space created within said cooler will directly reduce detrimental effects associated with an oxygen based environment to that of perishable products contained within said cooler, thus keeping said products fresher for extended periods of time. 3. A The vacuum based cooler as claimed in claim 1, wherein the total heat transfer from the exterior environment to that of the products contained within the vacuum based cooler when vacuum sealed is limited, products that are stored within said vacuum based cooler at ambient environment temperatures can have their temperatures reduced using a smaller amount of cooling substance due to the lack of additional thermal transfer from the exterior environment to said products.
