Abstract: An apparatus for delivering a volatile material in a continuous manner is disclosed. The apparatus includes a delivery engine having a reservoir for containing a volatile material; a rupturable substrate secured to the reservoir; a rupture element positioned adjacent to the rupturable substrate; and a breathable membrane enclosing the reservoir, rupturable substrate and rupture element. In some embodiments, the apparatus includes a housing having a notch for compressing the rupture element and breaching the rupturable substrate as it is inserted into the housing.

Abstract: The present invention generally relates to volatile substance evaporators having a container with wick, and has the object of providing a technique for effectively detecting end-of-life of the volatile substance housed within the container. The volatile substance evaporator is configured for coupling to, and maintaining in a stable position, a container of volatile substance having a wick with a lower end housed within said container and an upper end emerging from the container. The evaporator comprises an infrared light emitter disposed so as to emit a beam of light on said upper end of the wick, in such a manner that a receptor is disposed so as to capture said beam of light reflected by the upper end of the wick.

Abstract: The invention refers to an electrical heating evaporator for evaporating active substances such as perfumes and/or insecticides, in which the means for regulating the evaporation rate comprises an electrical heater resistor for which the power supplied is regulated through a potentiometer constructed on a printed circuit board. The evaporation rate can be adjusted for a wide variety of types of chemical substances, without the need of substantially modifying the design of the device.

Abstract: A vaporizer device of the type which is connected to the electric mains by a plug (1), incorporating a single container (6) equipped with a body of two or more independent receptacles (8) which hold different liquid fragrances in which respective wicks (2) are immersed and a lid (9) which closes the body (7) and renders the receptacles (8) independent. The lid (9) comes with openings (10) in correspondence with the positions of the wicks (2) for the egress and vaporization of the fragrance by actuation of one or more resistance elements (3), located in opposition to the openings (10), either with use of a manual pushbutton (4) or automatically in accordance with a pre-established program, diffusing the fragrances in a sequential or combined manner during predetermined intervals of time.
