<p>A three-compartment, instant hot or cold, reusable cold pack (10, 36) for transferring heat to or from an object. A first compartment (18, 38, 51, 62) contains a predetermined amount of a solvent (19) comprised primarily of water. A second compartment (20, 40, 46, 64) contains a predetermined amount of a solute (21) capable of essentially completely dissolving in the solvent. A third compartment (22,44, 48,66) contains a gelling agent (23) capable of gelling with the solvent and solute solution and producing a gel that is relatively soft and moldable when frozen.</p> |
