Beschreibung
Zusammenfassung:	The invention is directed to a device for evaporative delivery of volatile substances. The device includes (a) a reservoir portion containing a liquid volatile substance, the reservoir having an open cavity with a peripheral portion; (b) a microporous membrane having a first and second surface positioned over the reservoir, said membrane being affixed to the peripheral portion of the reservoir and wherein the second surface of the membrane contacts the liquid volatile substance, the microporous membrane further including a barrier coating layer over the first surface of the microporous membrane; and (c) a removable cap layer having a first surface and a second surface, wherein an adhesive layer is interposed between the first surface of the microporous membrane and the second surface of the cap layer such that the microporous vapor-permeable membrane and the liquid volatile substance are substantially sealed beneath the cap layer.
