US Patent 7540473 Dispensing system for a volatile liquid

A dispensing system for a volatile liquid, comprises a motorized fan adapted to generate an air stream and a capillary member having a body, in which a portion of the body is positioned within the air stream when the fan is activated. The portion of the body of the capillary member is impervious to passage of the air stream through the body in a direction of the air stream. The portion of the body is positioned in the air stream such that the air stream passes unobstructed over opposing surfaces of the capillary member aligned generally transverse to the direction of the air stream.
