This container contains a wick which is associated with the heating element with a wick end protruding from container . The heating element can be longitudinally displaced near the container in the housing relative to the wick end to adjust the degree of evaporation. According to the invention, the heating element is carried on a movable heater assembly that can be displaced longitudinally in the housing relative to the wick end. The movable heater assembly can be fixed in different positions relative to the wick end and the longitudinal direction of the wick axis for the adjustment of the degree of evaporation.
