ABSTRACT:
An aroma-dispensing cartridge and holder assembly attachable to an air vent in the interior of an automobile. When activated, the assembly functions to diffuse an aromatic vapor into the forced air stream emitted through the vent into the interior. The assembly is constituted by a holder provided with an array of parallel slots and a replaceable cartridge which is telescoped therein. The cartridge contains a porous pad impregnated with a liquid scent and includes a like array of slots. The inserted cartridge is axially shiftable relative to the holder from an inactive position in which the holder and cartridge slots are out of registration to effectively seal the pad, to an active position in which the slots lie in registration, as a consequence of which the forced air stream from the vent passes through the porous pad to volatilize the liquid scent.
