Aroma-dispensing cartridge and holder assembly for automobiles

Claim 1

An aroma-dispensing system comprising a cartridge and holder assembly which when activated functions to diffuse an aromatic vapor into a forced air stream intercepted by the assembly, said assembly operating in combination with means in which said stream is emitted through a vent grill formed by at least one slat, said assembly comprising: A. an open-top holder having a rectangular cross section, the front and rear walls thereof having corresponding arrays of parallel slots, said holder being provided at its rear wall with releasable clip means provided with a pair of cooperating flexible elements engaging the slat of the grill to secure the assembly thereto, whereby the forced air therefrom is intercepted by the assembly; B. a cartridge telescopically receivable in the holder and having front and rear walls provided with similar arrays of parallel slots, said cartridge housing a pad of porous material permeable to said forced air stream and impregnated with a liquid scent; and C. control means to render said cartridge axially shiftable relative to the holder from an active position in which the holder and cartridge slots lie in registration, thereby permitting the forced air stream to pass through the pad to volatilize the liquid to produce said aromatic vapor, to an inactive position in which the slots are out of registration to effectively seal the cartridge.
