An emanator for emanating a composition into its surroundings, the emanator comprising: a container for containing a volatile liquid comprising a composition to be emanated; an emanation surface from which the volatile liquid evaporates; a wick for transporting the volatile liquid from the container to the emanation surface, characterised in that the transport of the liquid through both the wick and the emanator occurs at the surface of both the wick and the emanator and in that transport of the liquid through the wick occurs only at the surface of the wick by capillary action. In a preferred embodiment the wick and the emanation system are integrally formed from a material formed with microgrooves.
An emanator for emanating a composition into its surrounding, the emanator comprising:
An emanator for emanating a composition into the surroundings, the emanator comprising:
An emanator according to any one of the preceding claims wherein the wick portion of the system comprises material having a microstructure in the form of substantially parallel grooves, each having a width in the range of 50 microns to 750 microns and positioned adjacent one another.
An emanator according to any of the preceding claims wherein the emanation portion of the system comprises a microstructure comprising microgrooves which fan out from the wicking microgrooves to form an emanation surface having a surface area to volume area that is large.
An emanator according to any one of the preceding claims wherein the rate of wicking and emanation results in a release rate of 0.1 cm3 to 10 cm3 per day of the fragrance.
An emanator essentially as herein before described with reference to the accompanying drawings.
