Abstract
The present invention relates to dispensers for active materials, which dispensers employ heat conductive elements to distribute heat from a burning flame at a wick to a simmer plate and to the body of a solid fuel containing the active material, so as to more rapidly liquify the solid fuel, such as paraffin wax, and to more uniformly and intensely heat such fuels to volatilize the active material. The heat conductive elements and simmer plate are configured so as to engage said solid fuel, and to cause the flow of liquified fuel to the wick. The fuel may comprise various active ingredients, such as fragrances, air fresheners, deodorizers, odor eliminators, odor counteractants, insecticides, insect repellants, herbal and medicinal substances, disinfectants, sanitizers, mood enhancers, aroma therapy compositions, and the like, and may be provided in various forms.
