Abstract
An air freshener for use, for example, in an automotive vehicle in which an annular scented pad is disposed within a hollow housing formed of mating, shallow, pan-shaped tray sections. One of the tray sections includes an annular axial hub. The other tray section has a guide extending outward therefrom and engageable with the hub to releasably secure the tray sections together with the scented pad entrapped therein. A restraining ridge about the hub holds the pad in position. A double sided pressure sensitive adhesive is fastened to one of the tray sections and is used to secure the housing to a surface within the atomotive vehicle in immobile fashion.
