Abstract:
A personal cooling device that provides cooling to a user, e.g., a wearer's feet, assuring even temperature distribution across contoured surfaces irrespective of the orientation of the personal cooling device and regardless of the pull of gravity. The personal cooling device includes a flexible non-porous upper component, a flexible non-porous lower component, a porous absorbent carrier component, at least one dry chemical reactant and at least one containment including at least one liquid reactant. The carrier component includes at least one dry chemical reactant distributed on the surface area thereof. When the at least one dry chemical reactant is combined with the at least one liquid chemical reactant and is absorbed by the carrier component, an endothermic reaction is produced. The carrier component absorbs the resulting cool substance evenly distributed thereover and, thereby assures equal distribution of this actual cooling throughout the entire device. The at least one containment is adapted to rupture under applied pressure. The upper and lower components are inseparably sealed to each other at their respective perimeters, the attachment forming a volume adapted to encapsulate the carrier component, the at least one dry chemical reactant and the at least one containment.

Claim (Index 31):
A cooling insert for cooling a user's foot in footwear, comprising:\n flexible, non-porous upper and lower substrates attached to each other to form an interior volume; said substrates being configured to conform to a contour of an insole for the footwear; a carrier and at least one frangible liquid containment that are one over the other inside said interior volume, wherein the carrier extends over substantially the entire area of the insert except for peripheral margins of said interior volume; at least one chemical reactant distributed over the carrier area inside said interior volume of the insert; said at least one chemical reactant comprising both (i) individual first particles and (ii) individual second particles that are larger than the first particles; and said interior volume having unwanted air evacuated therefrom to cause the upper and lower substrates to envelop and hold the carrier, the at least one containment, and the at least one chemical reactant in place in said interior volume, with the at least one chemical reactant distributed relative to the carrier; wherein:\n the liquid and at least one chemical reactant produce an endothermic reaction when in contact to thereby cause cooling; \n the at least one containment is configured to rupture in response to selected pressure, releasing a liquid therefrom to contact the at least one chemical reactant and cause the endothermic reaction; \n the individual first particles and the individual second particles in the at least one chemical reactant provide both initial and extended cooling, wherein the larger individual second particles extend the cooling beyond the period provided by the first particles alone; \n said peripheral margins are configured to provide room in said interior volume for any excess air or liquid; and \n the carrier is configured to absorb cooling liquid resulting from the endothermic reaction and upon pressure exerted by a user's foot to facilitate migration of some of the liquid from a higher-pressure area toward a lower pressure area of the insert.
