  • Patent number: 5906298
    Abstract: The scent dispersal system of this invention includes a reservoir for holding a liquid scent, a cap to close an opening in the reservoir, a conduit extends outward from the cap, a wick extends from the reservoir's interior to the exterior via the conduit and a way is provided to attach the scent dispersal system to an individual. A wick retainer is used to prevent pulling the wick from the reservoir and to retain the end of the wick in the liquid scent. A tube plug is used to close and seal the end of the conduit. Through capillary action the scent is automatically drawn to an exposed end of the wick extending outward from the end of the conduit. The scent is automatically dissipated or dispersed from the exposed end of the wick. As one walks, the scent creates a trail by rubbing off on grasses, leaves or other flora in the woods. At a fixed location the scent is dissipated by evaporation from the wick. Strength of the scent is controlled by the amount of the wick exposed.
