Abstract

The present invention relates to a system which enables a person to cool a particular portion of their body. The cooling is achieved through the use of a canister of compressed air which is dispensed over the portions of the user's body to be cooled. Portability of the canister is afforded through the use of a resilient belt clip. Furthermore, a directional cone is secured adjacent the dispensing end to enable a more accurate placement of the cooling air.

Claims9

Dependent claims

A portable belt worn personal cooling system comprising in combination:

a metallic thin walled cylindrical canister having a diameter, an interior, an upper end, a lower end and an intermediate exterior surface therebetween, a lower base coupled to the lower end of the canister and having a diameter larger than the diameter of the canister, the metallic thin wall effecting heat transfer from the interior to the exterior of the canister;
a compressed gas consisting essentially of Nitrogen and Oxygen positioned within the interior of the canister;
a stem having a lower and upper end, the stem secured within the upper end of the canister and interconnected to the interior of the canister, a filter positioned within the lower end of the stem, the filter having openings which remove particles unfit for human consumption, and the filter being constructed from a material which absorbs any chemicals unfit for human consumption;
button having an upper surface, a forward portion, a rearward portion and a cylindrical surface interconnecting the forward and rearward portions, a lower end with opening therein, an opening formed within the forward portion, a passage interconnecting the opening of the lower end and the opening of the forward portion, the upper surface sloping from the forward toward the rearward portion;
a plastic insulating cone having a proximal end and a distal end, the proximal end interconnected to the opening formed within the forward portion, the insulating cone functioning to prevent thermal contact between the air exiting the canister and the ambient air
a resilient plastic belt clip having two semicircular canister engaging portions and a belt securing portion interconnecting the two canister engaging portions, the two semicircular engaging portions together defining a diameter, the belt securing portion being intermediate of and perpendicular to the two semicircular canister engaging portions, the belt clip constructed from a resilient thermoplastic material which affords a degree of flexibility, the diameter of the two engaging portions being substantially the same diameter as the canister and being deformable to a diameter substantially larger than the diameter of the canister.
