Abstract
Described is a dispensing unit of a volatilizable substance capable of visible determination of its extent of use. The unit has a variably located centroid initially positioned proximate the geometric center point of the unit with the centroid moving downward when the unit is in use. As the volatilizable substance evaporates, a weight eccentrically located in the same place as the volatilizable substance angularly rotates about the 'z' axis leaving its upper position and finally coming to rest at a lower position when the volatilizable material is used up. At least the final position is rendered visibly detectable by means of a simple sighting mechanism.
