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.

Controlled release of substances

The present invention is directed to a device for delivering a fluid to the surrounding environment. The device includes a housing having an interior region and at least one opening, a fluid contained within the interior region, and a device means to force the fluid through the opening, and against gravity. Such a forcing device preferably comprises a gas generating pump, designed to force fluid positioned below the opening through a channel or conduit and out of the housing. Moreover, the opening in the housing may be associated with a member for controllably releasing fluid from the housing, for instance one or more porous plugs, an emanator pad, a decorative element or an adjustable valve. Additionally, the invention contemplates the use of a moveable member, such as a piston, flexible bladder, or expandable bladder, to separate the fluid from the gas generating pump and assist is forcing fluid out of the housing.
