Abstract: The invention pertains to coolers. Prior cooler designs had an unsegregated implicit void of unused air volume. This void was conducive to air eddy currents, which resulted in accelerated warming of the contents. The invention provides the means to disrupt the air eddy currents through a series of collapsible/expandable air cells. The disruption results in the increase of the insulation ability of the cooler. The collapsible/expandable feature allows the cooler to have content added/removed as needed, and allows the air cells to be increased in volume when content is removed.
