Patent ID: 7509692

Claim:
A personal cooling and hydration system, comprising in combination: a heat transfer fluid; said heat transfer fluid contained within a heat transfer fluid pathway; said pathway adapted to be located proximate to a body of a person, such that heat can be transferred from the body to said heat transfer fluid when the body is hotter than said heat transfer fluid; a heat sink material; said heat sink material adapted to be drinkable; a walled enclosure; said walled enclosure adapted to hold said heat sink material within an interior thereof; said pathway adapted to be located proximate to an exterior of said walled enclosure, such that heat can be transferred from said heat transfer fluid to said heat sink material when said heat transfer fluid is hotter than said heat sink material; an outlet for said heat sink material to facilitate drinking thereof; and wherein an elevated pressure air space is located on a side of said pathway opposite said walled enclosure where said pathway is located proximate to said exterior of said walled enclosure, such that said elevated pressure air space applies a force tending to press said pathway against said exterior of said walled enclosure.
