  • Air freshener device with visual signal means
    Patent number: 5163616
    Abstract: An air freshener device which indicates when air freshening fragrance formulation contained therein is consumed. The device has a plurality of chambers which contain the same or different fragrance formulations. The inner walls of the chambers are contrastingly colored with respect to the fragrance formulation so that, when the fragrance formulation is consumed, the colored walls are exposed indicating to the user that the formulation within that chamber has been depleted. The multi-chamber feature of the device provides the possibility of multiple fragrance choices and, at the same time, allows for the release of fragrance for an extended period of time.
