Abstract

Abstract The present invention is directed to a reusable thermal pack that comprises a bag formed of a water-permeable fabric defining a plurality of laterally adjacent compartments, and a superabsorbent polymer disposed in the bag compartments, wherein the polymer forms a gel in the presence of an aqueous solution, and the bag compartments are gel-retainable. The thermal pack of the present invention can be applied as a cold or hot compress for medicinal purposes, and also as an aid for cooling down following exercise. The thermal pack of the present invention, once hydrated in the presence of the aqueous solution, becomes cool and stays cool for several days without refrigeration, and can be made cooler if chilled in the refrigerator or freezer, or warmed if placed in the microwave, if desired.
