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 21):
A footwear insert for cooling a user's foot, comprising:\n flexible, non-porous upper substrate and lower substrate sealed at their peripheries to each other to form a laterally elongated interior volume and shaped to conform to a contour of an insole of the footwear; an elongated absorbent carrier and at least one frangible liquid containment, both inside said interior volume and both extending in area along and across the interior volume except for peripheral margins within said interior volume; at least one chemical reactant that also is inside the interior volume and is distributed relative to the area of the carrier and the at least one containment; 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 upper and lower substrates being configured to hold the carrier, at least one containment, and at least one reactant in place between the substrates and maintain the at least one reactant distributed relative to the carrier; wherein:\n when in contact with each other, the at least one reactant and a liquid from the at least one containment produce an endothermic reaction to thereby cause cooling; \n the at least one containment is configured to rupture in response to selected pressure, thereby releasing liquid therefrom to contact the at least one reactant and cause even cooling over the area of the carrier; \n the carrier is flexible following contact with the liquid after the at least one containment is ruptured, thereby facilitating conformance of the insert to the footwear, the insole, or an orthotic in the footwear; \n the individual first particles and the individual second particles in the at least one reactant provide both initial and extended cooling, wherein the larger second individual particles extend the cooling beyond the period provided by the first particles alone; \n said margins are configured to provide room in said interior volume for any excess air remaining in the interior volume after said sealing or excess liquid after the at least one containment is ruptured and the cooling reaction starts; and \n the absorbent 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 cooling liquid from higher pressure portions to lower pressure portions of the insert.
