Abstract
This invention provides an air freshener dispenser device comprising (1) a disposable air freshener cartridge which has an affixed electrical-resistance heating element on its upper section surface, and (2) an electrical plug housing. The cartridge has an elongated thermoplastic hollow body configuration with a sealed internal reservoir chamber of liquid air freshener medium, and the upper section of the cartridge body is shaped to a flat shallow extension of the cartridge chamber. A thin wick matrix extends internally from the cartridge chamber bottom up to the top of the chamber shallow extension. The cartridge has an integrally structured means adapted for removal of a top portion of the cartridge chamber shallow extension to expose an upper section of wick matrix to the atmosphere. The electrical plug housing is detachably secured and positioned proximate to the cartridge heating element. Activation of the heating element promotes air freshener dispersion into the atmosphere from the exposed wick.
