Abstract: The device for diffusing volatile substances comprises two containers (1, 2) to hold respective liquids with respective volatile substances. Each container has at least one aperture closed by a cap (12, 22). The device is configured so that it can be located on a supporting surface with the containers (1, 2) vertically confronting, so that one of the containers is selectively in an upper position or in a lower position with respect to the other container. The container which is in the upper position emanates the volatile substance which it contains, and the other one does not emanate the volatile substance which it contains.

Abstract: 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.
