an adjustable , refreezable heat removing cooler for refrigerating and insulating a variety of products such as variously sized beverage containers , frozen dinners , reusable plastic food left - over containers , or other objects . the cooler provides a cover having an inner and an outer layer of urethane coated nylon fabric that is sewn to form an envelope - like jacket . an array of refrigerant pouches in an elongate refrigerant bag carry a freezable refrigerant , such as blue ice , or a similar reusable refrigerant . an insulation layer of thinsulate or similar insulation slows heat energy transfer through the outer lay of urethane fabric . lack of insulation between the inner layer of fabric enhances heat energy flow from the item being cooled into the refrigerant . an elongate strip having hook fasteners on one side and loop fasteners on the other side allows the user to attach the cooler to a variety of objects having different circumferences . a velcro strap perpendicular to the elongate cover allows the user to adjust the cooler and in particular supports the bottom of a soft drink container . two or more such coolers may be linked together to encircle larger objects .
