Abstract
Embodiments of the invention provide a fragrance distribution device comprising an electrical resistor, a plug or other power source, and a fragrance in a polymer or thermoplastic carrier. The polymer or thermoplastic carrier may include, for example, metal inclusions, which may be powdered metal. These metal inclusions are believed to enhance heat distribution throughout the carrier, thus allowing a more uniform and reliable release of fragrance.
