ABSTRACT:
An electrically controlled pump (20) for dispersing a volatile substance into a local environment includes an enclosure defining a volume, a moveable member (52) separating the enclosure into first (54) and second (56) chambers (the second chamber containing non-solid composition which includes a volatile substance), an electrochemical cell (48) for generating gas. The electrochemical cell is associated with the enclosure, and is in fluid communication with the first chamber. A port preferably communicates the second chamber with a medium for dispersing the volatile substance into the local environment. Also, a case (58) may encase the pump and hold it in an upright position with respect to a surface upon which the case is positioned.
