ABSTRACT:
A disk shaped air freshener includes opposed mating trays which define a cavity therebetween and which are engaged for rotation relative to each other. Windows are defined in both of the trays, and openings to the cavity are increased, decreased, or shut entirely by relative rotation of the trays to alter the alignment of the windows. One tray has an axial sleeve and the other has several cantilevered arms which fit through the sleeve and which engage a radial groove in the sleeve to the hold the trays together in relatively rotatable fashion. A scented element is confined within the cavity between the trays and is allowed to provide a freshening scent through openings defined by the aligned windows in the tray. An adhesive pad is centrally located on one of the trays at the axial center of the air freshener.
