Abstract
A device for passively diffusing a liquid to the air of a surrounding area. A reservoir holds the liquid, the reservoir having a top end with an aperture therethrough. A non-planar wick extends through the aperture such that a lower end of the wick remains in contact with the liquid in the reservoir and an upper end of the wick is exposed to the surrounding area. The wick is formed of a fibrous, porous sheet of material having a top edge and a bottom edge of substantially the same width. The sheet of material is gradually gathered along a length of the sheet of material such that the upper end of the wick is less gathered than the lower end of the wick and the wick is self-supported in an upright position within the aperture.
