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.

Abstract: An assembly and method are provided for storing and dispensing a soluble substance, such as a flavoring, into a liquid. A useful application of the subject invention includes the case where lime-flavored liquid is contained in a foam artificial lime stored in the neck of a beer bottle, attached to a beer bottle or can, or attached to the 6-pack or 12-pack carton. The artificial lime may be retrieved from the neck or a protective covering and acted upon so it diffuses the lime-flavored liquid into the beer when it is inserted into the beer bottle. Alternately, juice from the artificial lime may be squeezed into the beer, or the artificial lime may be simply retrieved and discarded. Rather than needing to buy a natural lime, cut it up and push a wedge into a beer bottle, an artificial lime, or a packaged natural lime, may be stored directly in or with the beer bottle and placed in functional contact with the beer at time of consumption.
