Patent

CA 2059316

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.

Dispositif assainisseur d'air avec indication de consommation de la formule de fragrance contenue dans le dispositif assainisseur d'air. Le dispositif comporte une pluralité de chambres contenant soit la même formule de fragrance, soit des formules différentes de fragrances. Les parois intérieures des chambres sont de couleurs contrastantes par rapport à la formule de fragrance, de telle sorte qu'une fois la formule de fragrance consommée, les parois de couleur deviennent apparentes, ce qui indique à l'utilisateur que la formule de fragrance qui était contenue dans la chambre particulière est consommée. La construction à chambres multiples permet de choisir plusieurs fragrances et permet également de libérer les fragrances pendant une période prolongée.
