Collapsible Air Cells in a Cooler to Produce Temperature Gradient Chambers to Increase Insulating Ability

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.

What is claimed is: 
     
         1 ) A collapsible/expandable air eddy current obstructing layered air form composed of one to many layers of which each layer is composed of one to many cells for use in the unutilized volume in a cooler to increase the cooler's insulation capability. 
     
     
         2 ) The cooler insulation enhancement of  claim 1 , wherein the form is a self-inflating bladder with one to many sub chambers comprising of expanding material to automatically expand to occupy the unused volume for use in a cooler to increase its insulation capability. 
     
     
         3 ) The cooler insulation enhancement of  claim 1 , wherein the form is a series of one to many moveable plates to produce sub chambers in the unused volume of a cooler to increase its insulation capability.
