Dispensers and refills for volatile liquids, such as fragrances, are disclosed. Dispensers and refills in combination with dispensers according to the present invention may comprise a volatile liquid and a housing. In certain embodiments, the volatile liquid of the present invention has a predetermined evaporation rate, measured and calculated by the method described herein. In other embodiments, the volatile liquid exhibits a predefined relative evaporation rate. In addition to the housing, the present invention includes optional components, such as a motorized fan and/or a wick, to facilitate release of the volatile liquid into the atmosphere.

We claim: 1. An article of manufacture consisting of: a housing; a fan mounted to the housing to generate an air stream; between about 10 ml and about 15 ml of a volatile liquid carried within an enclosed reservoir, the volatile liquid having an evaporation rate between about 5.0×10−9 a
We claim: 1. An article of manufacture consisting of: a housing; a fan mounted to the housing to generate an air stream; between about 10 ml and about 15 ml of a volatile liquid carried within an enclosed reservoir, the volatile liquid having an evaporation rate between about 5.0×10−9 and about 10.0×10−8 meters per second measured with about 30% of the volatile liquid remaining at room temperature, as measured and calculated by drop shape analysis; and a wick extending between the volatile liquid and the air stream; wherein about 90% of the volatile liquid evaporates through the wick between within one and two months under ambient conditions at ambient room temperature when the wick is exposed to the surrounding environment. 2. The article of manufacture of claim 1, wherein the evaporation rate is between about 1.0×10−8 and about 7.0×10−8 meters per second measured with about 30% of the volatile liquid remaining at room temperature, as measured and calculated by drop shape analysis. 3. The article of manufacture of claim 1, wherein the volatile liquid has a relative evaporation rate of between about 0.50 and about 4.0. 4. The article of manufacture of claim 1, wherein the fan exhibits a throughput of about 0.4 cubic feet per minute to about 0.45 cubic feet per minute. 5. The article of manufacture of claim 1, wherein the air stream is intermittent. 6. The article of manufacture of claim 5, wherein the air stream is on and off in a ratio of about 1 minute to 3 minutes. 7. The article of manufacture of claim 1, wherein the volatile liquid comprises a fragrance. 8. The article of manufacture of claim 1, wherein the volatile liquid comprises an insecticide. 9. The article of manufacture of claim 1, wherein the volatile liquid is contained within a container that is adapted to be releasably secured to the housing. 10. The article of manufacture of claim 1, wherein about 90% of the volatile liquid evaporates in about 2 months under ambient conditions. 11. The article of manufacture of claim 1, wherein the wick is in alignment with the fan to immerse the wick into the air stream. 12. The article of manufacture of claim 11, wherein the wick has a mean pore size between about 1 micron and about 10 microns. 13. An article of manufacture consisting of: a housing; a porous wick associated with the housing; and a preselected volume of volatile liquid enclosed within a reservoir, the volatile liquid having an evaporation rate between about 5.0×10−9 to about 10.0×10−8 meters per second measured with about 30% of the volatile liquid remaining at room temperature, as measured and calculated by drop shape analysis, wherein the wick is in fluid communication with the volatile liquid and the surrounding environment, and wherein at least 90% of the volatile liquid evaporates within 2 months under ambient conditions at ambient room temperature when the wick is exposed to the surrounding environment. 14. The article of manufacture of claim 13, wherein the evaporation rate is between about 1.0×10−8 and about 7.0×10−8 meters per second measured with about 30% of the volatile liquid remaining at room temperature, as measured and calculated by drop shape analysis. 15. The article of manufacture of claim 13, wherein the volatile liquid has a relative evaporation rate between about 0.50 and about 4.0. 16. The article of manufacture of claim 13, further comprising a fan for generating an air stream. 17. The article of manufacture of claim 13, wherein the fan exhibits a throughput of about 0.4 cubic feet per minute to about 0.45 cubic feet per minute. 18. The article of manufacture of claim 13, wherein the air stream is intermittent. 19. The article of manufacture of claim 13, wherein the air stream is on and off in a ratio of about 1 minute to 3 minutes. 20. The article of manufacture of claim 13, wherein the volatile liquid comprises a fragrance. 21. The article of manufacture of claim 13, wherein the volatile liquid comprises an insecticide. 22. The article of manufacture of claim 13, wherein the volatile liquid is contained within a container that is releasably secured to the housing. 23. The article of manufacture of claim 13, wherein the preselected volume of volatile liquid is between about 10 ml and about 15 mil. 24. The article of manufacture of claim 13, wherein the wick has a mean pore size between about 1 and about 10 microns.
