ABSTRACT:
This invention provides an air freshener dispenser device with a nonporous wicking feature, which in an operational mode consists of (a) a first container with an upside open end, (b) a second container which is inverted and internally-nested within the first container with a downside open end and an upside closed end, and with the sidewalls of the two containers in a capillary spacing proximity, (c) a top-surface closure in the first container which is a vapor-emanating surface mechanism, such as an absorbent matrix, that is in contact with the upside closed end of the nested second container, and (d) a content of air freshener medium confined within the nested second container. The capillary spacing proximity of the container sidewalls provides a nonporous wicking mechanism for transmission of the liquid air freshener medium from the interior reservoir to the vapor-emanating surface for evaporation into the atmosphere.
