Patent ID: 8882998

Claim:
A device for dispensing an active liquid volatile substance into the surrounding atmosphere, said device comprising: a housing or a supporting frame, an assembly for providing forced ventilation of an evaporation surface impregnated with said active liquid volatile substance, the assembly comprising: a reservoir containing the active volatile substance and having an upper part that includes an opening; a cap lodged in the reservoir opening; at least one emanating member comprising said evaporation surface, the emanating member formed of a material capable of being impregnated with said active volatile substance and of allowing evaporation thereof into the device's surroundings; and at least one wick member formed of, or carrying, a porous material part capable of being impregnated with said active volatile substance, said wick member lodged through the cap into the reservoir opening so that a first portion of the wick member extends above the cap and a second portion of the wick member extends below the cap, wherein the wick member is in a position allowing it to be impregnated with the volatile substance, the second portion of the wick member does not move in relation to the reservoir, and the first portion of the wick member and the emanating member form a wick/emanating structure; a pivot directly connected to the cap that is lodged in the reservoir opening, wherein the assembly is arranged on the pivot so that the wick/emanating structure swings back and forth above the pivot and the second portion of the wick and the reservoir swings back and forth below the pivot, with the wick/emanating structure swinging back and forth for a period of time to cause forced ventilation of the evaporation surface of the emanating member; wherein the wick member is lodged in the device in a position allowing the second portion of the wick member to be in contact with the active volatile substance so that the active volatile substance can impregnate the wick member and the emanating member, and wherein the swinging movement of the wick/emanating structure, the reservoir and the second portion of the wick is triggered by manual, mechanical or electronically powered displacement.
