The device comprises conventionally a plug ( 2 ) for the electrical supply of a heater element ( 14 ) to bring about the heating and evaporation, by way of a flat wick ( 10 ), of an active substance contained in a main receptacle ( 5 ). The novelty lies in the fact that said container ( 5 ) is heat-formed and defines a triangular configuration reservoir ( 6 ) with a flat extension ( 7 ) that accommodates the flat "Y"-shaped wick ( 10 ) in which the ends of its divergent arms ( 11 ) are engaged in recesses ( 9 ) in the mouth of the active substance reservoir ( 6 ), said wick ( 10 ) being pressed by an impermeable strip ( 12 ) which is heat-sealed to the body of the reservoir ( 6 ), so that the heater element ( 14 ) positioned facing the front end of the extension ( 7 ) brings about the warming of the wick ( 10 ) and the corresponding evaporation of the active substance, which will issue by way of a hole ( 16 ) in the impermeable strip ( 12 ) to be diffused in the environment. In the plug-in position the device remains with the container ( 5 ) of the wick ( 10 ) in the vertical position, and in direct contact of this with the active substance contained in the reservoir ( 6 ).
