Abstract
Abstract A head or wrist sweatband including united sheet sublayers of foraminous heat conductive foraminous and moisture absorbant fabrics, for immersion in tap water at room temperature, functioning to evaporate the water with concurrent cooling of the human body and absorption of perspiration. The inner surface of the band is comprised of said heat conductive foraminous fabric first sublayer and in use is adjacent the skin of the wearer. Said moisture absorbant second sublayer is connected in interfacial association upon said first sublayer and forms the outer surface of said band. In use, the band is initially immersed in room temperature water and placed upon the user. Heat from the body of the user raises the temperature of the first sublayer which in turn raises the temperature of the second sublayer causing evaporation and consequent cooling of the band. Perspiration from the user is absorbed by the second sublayer for continous evaporation and cooling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
A laminated cooling band for a person comprising: (a) an air pervious heat conductive first sublayer of a screen of a foraminous glass fabric; (b) an air pervious fabric second sublayer of cotton fabric, said cotton fabric is a moisture absorbent material; and (c) uniting means for connecting said first sublayer and second sublayer in interfacial contact, said uniting means rendering said first and second sublayers in separably pliable interfacial association but for said uniting means uniting said sublayers into said cooling band; said first and second sublayers being free of substances affecting the porosity of said glass fabric and said cotton fabric subassemblies and resultant air passage therethrough; said first sublayer and second sublayers have peripheral edges and are joined at their edges using said uniting means, said edges are aligned, said uniting means being generally arranged parallel to the aligned said edges and closely spaced therefrom; said peripheral edge of said heat conductive first sublayer is exposed to the atmosphere; said laminated cooling band forms part of a cooling band system in the form of an endless loop for lowering the body temperature of a wearer, said first sublayer is the inner surface means for skin contact, said second sublayer comprising the outer surface means for holding water for evaporative cooling.
Claim 2
Dependent Claim
