Abstract: A device for delivering a volatile fluid in a continuous manner, over a period of time and without leakage, is disclosed. The device includes a flexible sheet and a semi-rigid sheet that are sealed along their edges to form a closed pocket or reservoir for containing a volatile fluid. The semi-rigid sheet is sealed on a first side to a flexible sheet and sealed on a second side to a vapor permeable membrane. The semi-rigid sheet contains a volatile fluid in the reservoir during storage, preventing contact of the volatile fluid with the vapor permeable membrane before the device is activated. The semi-rigid sheet has a differential score to guide the bounds of an opening that is formed upon activation. Once activated, the vapor permeable membrane provides continuous emission of a volatile fluid from the device.

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 nebulizing element for liquid substances for coupling to procurement elements, includes at least one membrane with a microperforated area; at least one piezoelectric element connected to an electronic circuit and coupled to the membrane to cause it to vibrate; at least one first and one second support that can be placed on top of one another and create, on their interior a compartment to contain the membrane, the piezoelectric element, and a space of limited dimension for the liquid to be nebulized, created beneath the membrane. The second support has an opening for the nebulized liquid outlet, located in correspondence with the perforated area of the membrane. The nebulizing element also includes at least one collector for the liquid that flows from the porous element to the collector itself by capillary action; at least one capillary opening to allow in the liquid to be nebulized and at least one outlet opening to aid air circulation.

Abstract: The present invention relates to an electric evaporator device of volatile substances with adjustable evaporation intensity. A heating plate (4) defines a first chamber (6) separated from a second chamber (8), wherein a heat generator (5) is located inside the first chamber (6). A regulation opening (13), located in the first chamber (6), allows the exit of a heated air flow from the first chamber to regulate the temperature both in the first chamber (6) and the heating plate (4), enabling thus the regulation of the evaporation rate.
