Abstract
This invention provides an air freshener dispenser device with a nonporous wicking feature, which consists of (a) a first container with an upside open end, and a downside closed end with a sharp piercing structure extending up from the interior bottom surface, (b) a second container which is inverted and internally-nested within the first container, with an upside closed end comprising a vapor-emanating means, and a downside end which is sealed with an impermeable membrane, and (c) a reservoir of liquid air freshener medium enclosed within the second container. The coextensive sidewalls of the two containers are in a capillary spacing proximity. For activation of the dispenser device into an operational mode, the second container is adjusted until the impermeable membrane is breached by the sharp-structure at the bottom of the first container. The released air freshener medium is transported by capillary action to the vapor-emanating surface for evaporation into the atmosphere.
