Abstract:
Aspects of the invention include an air freshener device that emits fragrance through the evaporation of a fragrance-containing fluid comprising: a container, comprising a particular volume of the fragrance-containing fluid; a wick disposed partially in, and partially out of the fragrance-containing fluid, the wick having an immersion section immersed in the fluid so as to displace a displacement volume of fluid and a non-immersion section extending outward from a surface of the fluid, the immersion and non-immersion section being disposed on opposite lateral ends of the wick; the wick further comprising a displacement portion and a wicking portion, the displacement portion being configured to displace a desired first volume of fluid, the wicking portion being configured to wick a second volume of fluid; the displacement portion and the wicking portion designed to achieve a desired ratio between the displaced first volume of fluid and the wicked second volume of fluid.
