  • Patent number: 7499632
    Abstract: A distribution device for distributing volatile fluids in air. In an exemplary embodiment, the distribution device includes a wick formed of a solid material which is impregnated with a volatile fluid, such as a scented liquid, a disinfectant, a fungicide, an anti-allergenic substance, an insect repellant, or an insecticide, for example. In another embodiment, the device includes a substantially hollow, tubular shaped wick which includes a portion that is exposed to the surrounding environment and a portion that is in liquid communication with a liquid reservoir containing a volatile fluid. The wick is positioned in the liquid reservoir and in a close fitting engagement with an open end of the liquid reservoir. The hollow configuration of the wick provides a greater exposed surface area to enhance the evaporation of the liquid into the surrounding environment.
