ABSTRACT:
A passive dispensing device for a liquid active material includes an upper housing portion for receiving a container for holding and dispensing a liquid active material, wherein the upper housing portion includes an interior cavity and wherein the container includes a wick extending from inside the container to an area outside the container. The device further includes a lower housing portion that extends downwardly from the upper housing portion, wherein the lower housing portion defines a recess between the upper and lower housing portions and includes first and second legs that extend downwardly from the upper housing portion and outwardly from the recess. The device has an operative position in which the first and second legs are disposed on a support surface, the container is retained in the recess with the wick extending upwardly into the interior cavity, and the container is spaced above the support surface and disposed between the first and second legs to allow convective air flow past the recess and the container through the device to dispense the active material from the upper housing.
