Abstract
An air freshener device (10) is disclosed. The air freshener device (10) includes a cartridge (12) having a housing (16). The housing (16) has a sealed first cavity (26) and a sealed second cavity (28). First fragrance (60) is located within the first cavity (26) and has a first volatility. Second fragrance (62) is located within the second cavity (28) and has a second volatility. First and second cavities (26) and (28) have first and second openings (64) and (66) respectively. First opening (64) is covered by a first removable cover (68) and second opening (66) is covered by a second removable cover (69). Alternatively, a single cover may be used for both openings. When the covers (68) and (69) are removed the fragrances (60) and (62) independently exit their respective cavities (26) and (28). The device (10) includes an outer housing (14) having a front member (70) which includes air passage openings (72). The outer housing (14) has a back member (74) adapted and configured to be mounted on a surface. Top member (78) and bottom member (80) connect front (70) to back (74). Top and bottom members (78) and (80) have openings (82) and (84) which define a slot (86) extending the length of the outer housing (14). The slot (86) is sized and configured to receive the cartridge (12) whereby when the cartridge (12) is expired a second cartridge (98) is inserted into the slot (86) proximate the top member (78) and the second cartridge (98) is moved in the slot (86) toward the bottom member (80), the cartridge (12) moves downward in the slot (86) and is forced out the bottom member (80) by movement of the second cartridge (98). The air passage openings (72) receive air which moves over the cartridge (12) picking up the fragrances (60) and (62) resulting in an air-fragrance mixture which exits the air passage openings (72) thereby allowing dispersion of the fragrances (60) and (62).
