The present invention is directed to a device for releasing a volatile substance. The device includes a housing having an interior region, a volatile substance contained within the interior region, and the ability to controllably release the volatile substance from the housing. Such controllable release can be accomplished by the housing being substantially permeable to ambient air, yet substantially impermeable to the volatile substance contained within the interior region of the housing. Additionally, the invention contemplates the use of one or more porous plugs for diffusing the volatile substance therethrough and eventually into atmosphere in a vapor form. To assist such diffusion, the invention likewise contemplates the use of an electrochemical gas generating cell, a heating element and/or other features which allow air to controllably enter into the interior region of the housing.

[ What is claimed is:] [1.] A device for releasing a volatile substance comprising:a housing having an interior region, an outer surface, and an opening in at least one end;a volatile substance contained within the interior region of the housing;means for orienting the housing such that gravity forces the volatile substance toward the opening; andmeans for controllably releasing the volatile substance from the housing, spaced apart from the housing by a gap, and at least a portion of which is positioned so as to receive fluid dripping therefrom, wherein the controlled release means includes an gas generating cell operatively associated with the interior region of the housing.
