Abstract
A vapor-dispersing device comprising a moveable piston with an evaporative member is described that operates by the repetitive movement of the piston to bring the evaporative member into repeated contact with the exposed end of a liquid transfer means to wick volatile liquid out from a reservoir onto the evaporative member and to expel vapors out through vents.
