Abstract
An automatic air freshener that operates for a period of time in excess of about 14 days, and that may optionally include a drain cleaner, mosquito repellant, or other beneficial fluid. Certain embodiments are adapted for disposal in a urinal, although a variety of other applications are contemplated. An air freshener may operate by: emanation of scent from a rubber or rubber-like material that carries a dispersed scented oil; gravity-induced drip from a bulk supply of scented fluid through a small orifice; osmotic transfer of scented fluid from a bulk supply; or gas-pump drive of scented fluid at controlled pressure. When present, the drain cleaner typically is carried by a container structured to permit a slow drip of drain cleaning fluid from a bulk fluid supply.
