Abstract: A fragrance delivery device, comprising a vapor releasing oleophobic microporous layer; a flexible impermeable barrier layer coupled to the vapor releasing oleophobic microporous layer at a perimeter thereof, wherein the microporous layer and barrier layer define a cavity; and a reservoir substance disposed in the cavity, wherein a volatile material of the reservoir substance is releasable from the fragrance delivery device via the micropores of the microporous layer when the fragrance delivery device is at ambient temperature.

Abstract: A fragrance delivery device, system, and method of use and manufacturing are disclosed. The device has a vapor releasing membrane including a plurality of micropores, wherein each respective micropore has a consistent diameter dimension in both a delivery condition and in a use-condition of the fragrance delivery device. The device further includes a flexible impermeable barrier coupled to the vapor releasing membrane along a perimeter thereof, wherein the vapor releasing membrane and impermeable barrier define a cavity there between having a predetermined volume. A substance is disposed in the cavity up to the predetermined volume, the substance comprising a volatile fragrance disposed in a matrix, wherein the substance has a first viscosity in the delivery condition and a second viscosity in the use-condition, the volatile fragrance being releasable from the matrix when exposed to a predetermined temperature and emittable through the plurality of micropores.

Abstract: A fragrance delivery device, system and method is provided, comprising a housing including a rupture device and an absorbent member receivable in the housing. The system further includes a cartridge insertable within the housing and containing a fragrance medium therein. The rupture device of the housing is engageable with the cartridge to release the fragrance medium from the cartridge into the housing. The absorbent member absorbs the fragrance medium and permeates a fragrance from the fragrance medium to an external environment.

Abstract: A dispenser for dispensing volatile components of an air treating gel, which stabilizes an emanating surface of an emanating face of an enclosed air treating gel, that is structurally simple and relatively easy to manufacture. The emanating surface of the gel attaches to a grille of an aperture member fast within and adjacent a major opening of the dispenser. The aperture member is designed to support the emanating surface continuously throughout the dispensation of the volatile components and may be sized to provide vacuum relief to a bottom surface of the enclosed gel. Accordingly, the emanating surface is replenished from a reservoir of gel within the dispenser while remaining supported by the aperture member.

Abstract: A dispenser for dispensing volatile products present in a gel in which the gel is anchored to the dispenser throughout the perimeter of an emanating surface of the gel from which the volatile products are dispensed. The emanating surface is replenished from a reservoir of gel within the dispenser while the emanating surface remains substantially stable and free of shrinkage as a result of its anchorage to the container. The anchoring means may be a porous material or appropriately shaped flanges and openings adjacent the emanating surface in the structure of the dispenser.

Abstract: A method for the fabrication of a continuous action reservoir type air freshening device is described. The device is characterized by the use of an evaporation rate controlling porous membrane which is in intimate contact and completely covers the exposed surface of an erodible gel-type of solid perfume composition. The fragranced gel is enclosed in a container, one end of which is open and over which is affixed the porous membrane. One side of this membrane is exposed to the atmosphere; the other side intimately contacts the solid reservoir consisting of the fragrance gel. Transmission of the volatile fragrance and carrier agents to the surrounding environment through the porous membrane matrix occurs as a function of an evaporative process. The membrane permits only a limited penetration, if any by the gel solution, i.e. in the liquid state, but is sufficiently permeable to the gel solution to establish physical attachment between the solidified gel and the membrane.

Abstract: A vapor dispersing device in which evaporative dispersion of volatile and diffusive components of an air treating agent is regulated over an extending period by the use of a container, for the agent, into which at least one rigid porous wick extends to transfer the agent from the container to a porous plastic element from the surface of which dispersion of the agent will occur by means of evaporation, the surface of the element being impregnated with an occluding agent, the evaporation rate of which is chosen, relative to rate of deposition on non-volatile components of the air treating agent in the element, to result in an even dispersion rate over a desired operating period.
