Odor dispensing device and odor dispensing cartridge

An odor dispensing device comprising a housing and a disc shaped cartridge adapted to move around its rotation axis and having a plurality of discrete radically arranged compartments, each compartment containing an odorant on an odorant carrier, said housing containing means for positioning the cartridge, means for producing an airstream to a pre-selected compartment in response to a signal emanating from a computer control module, a microprocessor, an optical system or a timing mechanism and means for temporarily subjecting the odor carrier within the compartment to the airstream so that an odor is discharged from the cartridge and entrained in the airstream, wherein the cartridge (3,32) has a basic body (4,34) with bottom (4f,51) and compartments (5,33) separated by walls, (a) which compartments (5) of the cartridge (3) can be tightly closed and opened by covers (11) working in axial direction of the cartridge (3) and against the flow of the airstream whereby in the closure position the covers (11) are pressed on opening edges (4a, 4b, 4c) of the walls, or (b) which each compartment (33) of the cartridge (32) has a closable inlet aperture (42) and an interrelated closable outlet aperture (43) for passing of a part the airstream, thereby in the opening position in both cases (a) and (b) picking up the particular scent of the odorant on the odorant carrier (6,58) which scented airstream is then discharged into the surrounding air of the housing (19,55).
