Abstract: A liquid dispensing system is described comprising a universal refill of liquid and an emanation device; wherein the refill comprises: a housing having an inner volume and an outer surface; at least one reservoir in the inner volume of the housing for holding the liquid; at least one aperture in the housing sealed by a sealing means; and at least one wick provided on or connected to the outer surface of the housing, wherein said wick(s) is not extend to the inner volume of the housing; and wherein the emanation device is selected from: an emanation device configured to spray the liquid; an emanation device configured to evaporate the liquid by electrically powered means; an emanation device configured to evaporate the liquid by passive, non-electrically powered means; an emanation device configured to emanate the liquid by two or more of spraying the liquid, evaporating the liquid by electrically powered means and/or evaporating the liquid by passive, non-electrically powered means; characterised in that each

Abstract: A universal refill of liquid containing one or more active materials is described wherein the refill comprises: a housing; at least one reservoir in the housing for holding the liquid; at least one aperture in the housing wherein the or each aperture is closed by a valve system comprising at least two valves wherein at least one of said valve(s) is configured to be automatically resealable when not being held open and at least one of said valves is provided in the form of an annular ring valve; and wherein the refill is configured to allow the liquid to be extracted by at least two different methods of liquid extraction. Systems comprising emanation devices and universal refills are also described.

Abstract: A refill for a liquid wherein the refill comprises: a housing; at least one reservoir in the housing for holding the liquid; at least one aperture in the housing sealed by at least one valve wherein said at least one valve defines a liquid pathway from the reservoir to the exterior of the refill, wherein at least one of said valve(s) is configured to be automatically resealable when not being held open; and at least one wick housed entirely within the housing.

Abstract: A device for emanating a liquid wherein the device is for use with a refill of liquid, wherein the device comprises: a housing with at least one exit port for emanated liquid therein; a hollow and elongate extraction limb having at least one aperture therein to define a fluid flow path from the said at least one aperture into the hollow extraction limb and to said at least one exit port; a heater that, in use, can transfer heat therefrom to at least a part of the extraction limb.

Abstract: A refill for a liquid wherein the refill comprises: a housing having an inner volume and an outer surface; at least one reservoir in the inner volume of the housing for holding the liquid; at least one aperture in the housing sealed by a sealing means; and at least one wick provided on or connected to the outer surface of the housing, wherein said wick(s) is not extend to the inner volume of the housing.

Abstract: A device for emanating a liquid is described wherein the device is for use with a refill of liquid, wherein the device comprises: a housing with at least one exit port for emanated liquid therein; a hollow and elongate extraction limb having at least one capillary tube therein, said at least one capillary tube being open at one end to extract liquid from the refill and open at the other end to deposit said liquid on at least one wick provided only on an outer surface of a refill housing.
