A number of recent developments include a liquid air-treating composition in an enclosure, all or part of which is formed of a polymeric film through which the air-treating composition can migrate to be released as a vapor at an outer surface.

There remains a need for a well-constructed air freshener dispenser device which can be mass-produced economically and which can deliver a vapor medium at a controlled uniform rate over an extended period of time. A thin wick matrix extends internally Reed Diffuser Factory from the cartridge chamber bottom up to the top of the chamber shallow extension. Various kinds of vapor-dispensing devices have been employed for this purpose. Other air freshener dispensers are inexpensive to produce, but tend to have inferior construction and functionality. The most common of such devices is the aerosol container which propels minute droplets of an air freshener composition into the air. The combination of heating element 36 and specific air freshener medium can be customized for optimum performance.

The need for effectively combating airborne malodors in homes and enclosed public buildings, by odor masking or destruction, is well established. Activation of the heating element promotes air freshener dispersion into the atmosphere from the exposed wick.. After usage, the device qualifies for disposal as a non-hazardous solid waste.

As a further advantage, a present invention air freshener dispenser device can be produced in high volume from relatively inexpensive plastic materials.

A significant advantage derives from the incorporation of heating element in the structure of disposable cartridge.

Wicking devices are well known for dispensing volatile liquids into the atmosphere, such as fragrance, deodorant, disinfectant or insecticide active agent. Other products such as deodorant blocks are also used for dispensing air-treating vapors into the atmosphere by evaporation.

Some air freshener dispensers are expensive to manufacture. 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 China Reed Diffuser Manufacturers to the atmosphere. The electrical plug housing is detachably secured and positioned proximate to the cartridge heating element. Another common type of dispensing device is a dish containing or supporting a body of gelatinous matter which when it dries and shrinks releases a vaporized air-treating composition into the atmosphere.

It is a further object of this invention to provide an air freshener cartridge for utility in a heat-activated air freshener dispenser device, wherein the cartridge has an internal air freshener reservoir in contact with a wicking means.
