ABSTRACT:
A vehicle air freshener is quickly and easily installable and removable from an outlet grille of the vehicle ventilating system. The air freshener includes a tube filled with a fragrance saturated absorbent material. The tube has a sufficiently small diameter to pass through the typical opening in a vehicle interior ventilation outlet grille, and includes a thin, elongate extension and handle which is wider than the grille opening, to preclude passage of the handle through the grille opening. The air freshener is initially provided with one or more sealed scent passages, which are punctured or otherwise removed to allow the scent or fragrance to escape the interior of the air freshener and mix with the air. After opening the scent passage seal, the air freshener is inserted into the ventilation grille opening and is prevented from falling into the ductwork of the ventilation system by the handle which is caught on the outside of the grille, thereby substantially concealing the air freshener. Any air flowing through the ventilation system will absorb the fragrance escaping from the opened scent passage and pass into the vehicle interior. The air freshener may be easily removed when the scent is depleted or no longer desired, by grasping the handle and withdrawing the air freshener from the duct and grille opening. At least the handle portion may be provided in different colors to closely match the colors of various ventilation grilles, in order to provide an unobtrusive appearance.
