Abstract: 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.

Abstract: A dispenser of actives having a linear release rate may be achieved by providing a volatile containing gel system wherein the gel system is proportioned in specified dimensional ratios, so that the sum of the rate of volatile release from directly exposed areas of the surface of the gel system and the rate of volatile release from areas of the surface of the gel system which are not in direct exposure to the atmosphere remains essentially constant through out the life of the dispensing device.
