Abstract
This invention provides an air freshener dispenser device which consists of (a) a transparent container which has a content of liquid air freshener medium, (b) a transparent nonporous insert sleeve which is coextensive with the container sidewall interior surface, and (c) a container closure comprising a vapor-emanating surface mechanism, such as an absorbent matrix, which is in contact with the insert sleeve. The insert sleeve surface and the sidewall interior surface are in a capillary spacing proximity which provides an upward wicking passageway for transmission of the liquid air freshener medium to the vapor-emanating surface for evaporation into the atmosphere.
