ABSTRACT:
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.
