Patent attributes
The invention involves an insulation device comprising of a pad defined by a length and a width suitable for fitting snuggly within a cavity of a cooler. In exemplary embodiments, the pad comprises a closed-cell polyvinyl chloride nitrile butadiene rubber foam, also known as PVC/NBR, the pad defined by dimensions including a certain thickness such that the pad may be compressed against the interior walls of the cooler cavity without collapsing or folding over. The edges of the pad may be pressed against the interior walls of the cooler cavity to form a compression seal throughout the perimetrical edge of the pad against the interior walls of the cooler cavity; the compression-sealed edge prolongs a period during which low temperatures may be maintained. The pad is preferably water resistant, lightweight, washable, sufficiently flexible and can be easily trimmed or cut to a desired size.
