Abstract: A method of delivering a volatile material to the atmosphere in a continuous manner is disclosed. The method includes providing a delivery engine having a reservoir that includes a volatile material mixture. The volatile material mixture includes about 40% to about 100%, by total weight, of the volatile materials each having a vapor pressure at 25° C. of less than about 0.1 torr. The delivery system also includes a microporous membrane enclosing the reservoir, wherein the microporous membrane comprises an average pore size of about 0.01 to about 0.03 microns.

Abstract: The invention refers to a container (1) for volatile substances having a first chamber (2) containing a porous material (4) impregnated with a first volatile substance, and a second chamber (3) containing a second volatile substance. The evaporation of the first and the second volatile substances is synchronized so that both volatile substances are finished substantially at the same time. The second volatile substance is used as a visual indication of the end of life of the first substance. The open base of the first and the second chamber are covered by a permeable film. The container may be arranged with a heater for the volatile substances.

Abstract: The present invention relates to a method and a device to evaporate low volatility active substances or ingredients from a liquid solution contained in a reservoir (2). The device comprises at least one liquid retaining support and dispensing means (14) arranged in a casing (1) at a distance and in a suitable position for dispensing doses of said liquid solution on said support by means of a push-button (6). The device further has a timer adapted to allow the operation of said dispensing means in selected time periods, said time periods being greater than the time necessary for evaporating most of the solvent and active ingredient from the support.

Abstract: The invention refers to a spray pump device for spraying a liquid operated by a memory shape element. The spraying device is provided with a memory shape alloy wire with electrical resistivity, that is able to generate heat that increases its temperature so that due to memory shape property, the wire shrinks when current is applied. This shrinking permits the wire to activate a pump that atomizes a volatile substance.

Abstract: The present invention refers to an evaporator device for volatile substances provided with a closure system that facilitates the replacement of the refill or container of the volatile substance. The invention provides a safety closure system for the evaporator device, which makes difficult for children to get access to the tablet or container of the volatile substance. A closure member and a container are associated in such a manner that during the opening movement of the closure member, at least part of the container is extracted out of the chamber.

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.

Abstract: An evaporator, for use with a bottle containing a substance to be evaporated and a wick that has its lower portion disposed within the bottle and its upper portion protruding from the bottle, includes a housing in which the bottle is retained, a fan, disposed within the housing, for creating an airstream, and a louver structure, disposed downstream of the fan, for directing the airstream created by the fan upwardly and away from the upper portion of the wick. Preferably, the louver structure includes a plurality of louvers inclined at an angle between about 20 degrees to about 60 degrees relative to horizontal.
