Device for dispensing a volatile substance
 A device for dispensing a volatile substance includes a gas-fueled, portable heat source. The heat source has a combustion nozzle capable of supporting a flame. The device includes a sole plate for heating the volatile substance and heat transfer means for enclosing the combustion nozzle and transferring heat from the flame to the sole plate. A heat box substantially surrounds the heat transfer means and sole plate. The heat box has a window through which volatile substances released from the sole plate may escape. The device also has a housing within which the heat box is held in spaced relation from the housing, the housing having a housing window adjacent to the heat box window. By use of the device, a flame at the combustion nozzle heats the sole plate to volatilize a volatile substance placed thereon, which may then escape into the atmosphere through the heat box window, with the housing remaining cool.
