ABSTRACT:
A volatile material dispensing device is provided, including a volatile material, a replaceable canister including a U-shaped outlet tube and a reservoir to hold the volatile material, and a generally cylindrical external housing sized and configured to receive the replaceable canister. The U-shaped outlet tube includes a tube inner leg, a tube crosspiece, and a tube outer leg, with the tube inner leg fluidly connected to the cavity and with the tube outer leg open to the atmosphere. The external housing includes a powered actuating unit configured to apply pressure to the flexible outer wall of the reservoir. Thereby a portion of the volatile material is forced up the inner tube, over the tube crosspiece, and down the outer tube to be received by a porous pad, providing a time-release dispersing mechanism delivering a controlled, consistent flow and producing a constant intensity of vapor release over time.
