[0033]Unlike any prior art design, this new-application apparatus utilizes carbon-dioxide pellets rather than block form or pressurized gaseous carbon dioxide. The Carbon-Dioxide Pellets enhance conformability of the garment and thereby increase design freedom, permitting adaptation to hats, vests, helmets, scarves, pants, blankets, seat covers, etc. Conversely, block dry ice offers limited adaptability to varied shapes. The conformability of the “Flexible Carbon D

first embodiment
[0055]The manner and process of using the Cooling and Impact Protection Safety Helmet 210 embodiment is achieved by means of the placement of suitably sized Carbon-Dioxide Pellets 100, most commonly derived from the extrusion process, into the Coolant Chamber 240. The exact process of use involves the removal of an access cover, called the Fill Cap 260A, from the Fill Port 260 at the origin point of the Coolant Chamber 240. This is followed by pouring the Carbon-Dioxide Pellets 100 through the Fill Port 260 into the Coolant Chamber 240. Vibration of the Cooling and Impact Protection Safety Helmet 210 by mechanically or hand applied means is applied until the Coolant Chamber 240 is full.
[0056]When the Coolant Chamber 240 is full, the Fill Cap 260A is reinstalled. The vibration serves to maximize the volume of Carbon-Dioxide Pellets 100 placed during the filling process by minimizing the formation of blockages and voids that may result from clumping together of the Carbon-Dioxide Pell...
second embodiment
[0065]The use of the Soft-Shell Design 300 embodiment involves orienting the garment with the Fill Port 350 at the highest vertical position. The Fill Port 350 is accessed by removal of the Fill Cap 350A. The Coolant Chamber 330 is then filled with suitably sized Carbon-Dioxide Pellets 101 by means of gravity and vibration assistance. The Fill Cap 350A is then placed in the Fill Port 350 and the garment is donned. Carbon-Dioxide Vapor 101 produced by the sublimation of Carbon-Dioxide Pellets 100 within the Coolant Chamber 330 escapes through the Carbon-Dioxide Vapor-Permeable Insulation Material 322B and overlying Carrier Fabric 324 toward the garment interior, whereby it absorbs heat. Subsequently, the heat-laden Carbon-Dioxide Vapor 101 diffuses out of the garment.

Abstract
The invention is a reusable personal cooling apparatus that utilizes exclusively pourable pellet forms of Carbon-Dioxide Pellets as an expendable coolant. This coolant is placed in one or more compatibly designed, refillable Coolant Chambers that are integrated into a wearable garment that can be either a Hard-Shell Design (by example, an impact-protection helmet) or a Soft-Shell Design (by example, a vest), or a combination thereof. The Carbon-Dioxide Pellets are of machine manufacture and high density. They enhance the conformability of the Soft-Shell Design garment, promote ease of filling both garment designs and make possible the application of the pellet form of coolant to rigid, thin, curved structures like a helmet.
The application of vibration expedites the speed of filling the apparatus and maximizes the fill volume by minimizing void formation within the Coolant Chamber. The cooling effect is achieved through the process of phase transition wherein solid carbon dioxide subliminates to Carbon-Dioxide Vapor which in turn is vented toward the skin of the individual wearing the garment. The ramifications are a versatile, reusable, convenient and diversely configurable personal cooling apparatus and a complementary coolant that function together to enhance personal comfort.
