Patent ID: 8043569

Claim:
A device for dispensing an active volatile substance into the surrounding atmosphere, provided with means for forced ventilation of an evaporation surface impregnated with the volatile substance, the device comprising: a reservoir containing the active volatile substance and having an upper part equipped with an opening; a wick/emanating member assembly comprising an emanating member carrying the evaporation surface and formed of a material capable of being impregnated with the active volatile substance upon activation of the device and of allowing evaporation thereof into air surrounding the device; and a wick member formed of, or carrying, a porous material part capable of being impregnated with the active volatile substance, the wick member being adapted to be lodged in the device through the opening of the reservoir's upper part in a position allowing it to be impregnated with the volatile substance and to be in contact with the emanating member, wherein, upon activation of the device, the emanating member and the wick member are lodged in the device in a position allowing the wick member to be in contact with the active volatile substance and to cause the emanating member to be impregnated therewith, and wherein the means for forced ventilation of the evaporation surface carried by the emanating member is operatively associated with the wick/emanating member assembly and comprises electrically, battery or solar powered means for providing repeated, rotating movement of at least the emanating member for a determined period of time, relative to the reservoir, with the device being devoid of any moving parts capable of causing forced ventilation other than the emanating member or wick/emanating member assembly.
