Abstract: An aroma-generating unit adapted to periodically discharge into the atmosphere bursts of aromatic vapor, the non-aromatic intervals between the bursts having a duration sufficient to avoid desensitizing the olfactory response of those exposed to the unit. The unit includes a hollow case whose upper wall has a vent therein and whose side wall has a slot to receive a replaceable cartridge provided with a porous mat impregnated with an aromatic liquid. When fully inserted, the cartridge is disposed below the vent and serves to define an air-confined chamber within the case. Disposed in this chamber is an electrical heater that is periodically energized by power pulses to heat and expand the confined air and to produce a positive pressure in the chamber forcing the heated air through the impregnated mat to rapidly volatilize the liquid and to produce bursts of aroma which are discharged into the atmosphere through the vent, which bursts are separated by relatively long, non-aromatic intervals.

Abstract: A disc-playing aroma generator whose appearance and function are analogous to those of a phono disc record player, the user when playing a selected aromatic disc enjoying an olfactory rather than an auditory experience. Each aromatic disc houses a supply of a liquid fragrance whereby when the disc is inserted in the player, an aromatic vapor is then discharged into the atmosphere. The disc is formed by a circular sheet of absorbent material impregnated with the liquid fragrance and sandwiched between a pair of annular plastic films which are peripherally joined to create a central zone exposing the impregnated sheet. In the player, heated air under positive pressure is forced through the central zone to volatilize the liquid to produce a vapor which is discharged through vents in the casing of the player.

The capsule, preferably formed of a flexible synthetic plastic skin, includes a top wall having a vent hole therein and a base wall provided with a pressure-sensitive outer coating to adhere the capsule to the bulb. Supported within the internal cavity of the capsule is a pad of porous material having good wicking properties impregnated with a volatile aromatic liquid. The pad is at a position within the cavity adjacent the top wall to define therebelow an air chamber which when heated creates a positive air pressure forcing a stream of heated air through the pad to produce a vaporous scent. This is discharged into the atmosphere through the vent hole.

Thus, the disclosed semistatic vapor dispenser continually provides the desired vapor concentration.An improved static vapor generator is also disclosed, the improvement permitting the static vapor generator to produce vapors at a more uniform rate during its entire lifetime.

Abstract: A deodorant or fragrance dispensing packet for use in vehicles and the like is characterized by being quickly rechargable by squeezing the two parallel sides of the packet together, which causes spikes molded on the interior of one side of the packet container to rupture a liquid fragrance containing pod, permitting the perfume to flow into a surrounding absorbent pad from which the fragrance slowly evaporates and disseminates into the atmosphere through holes in the outer casing which were punched by the consumer after purchase to permit the dissemination of the first charge of fragrance which was contained in the absorbent pad.

Abstract: A device for releasing a volatile substance into the environment in a controlled manner comprises a reservoir of substance-absorbent material, for storing the substance, that is encapsulated in an envelope, at least a portion of which comprises a permeable material having porosity at least equal to ultramicroporosity.

Abstract: A package and dispenser for a volatile air-treating or air-freshener material includes a container open at its upper end. A first layer of a porous material is permanently secured to the open end of the container and a second layer of a non-porous material is removably secured to the container over the porous layer. When it is desired to use the container to release vaporized aif-freshener material, the second layer is removed and the remaining porous layer allows the air-freshening vapor to permeate therethrough while at the same time retaining the remaining non-volatized material within the container.

Abstract: A package having plural layers with a quantity of volatile substance such as deodorizer sandwiched between the layers.

Abstract: An improved nozzle apparatus rapidly convertible, while operating, between spray and foam forming modes of operation. An elongate rigid generally cylindrical first conduit member receives surfactant bearing solution at an inlet port thereof and directs the solution under pressure to a spray forming nozzle connected at an outlet port of the first conduit. A second elongate conduit member coaxially slidably overlies the first conduit member and is movable relative thereto between extended and retracted positions. When in its retracted position, the second conduit member exposes the spray-forming nozzle, which is then enabled to direct a spray pattern of the solution longitudinally outward from the apparatus. When in its extended position, the second conduit member encompasses the spray-forming nozzle, and aspirates the spray therefrom with air to form foam which is ejected longitudinally outward from the second conduit member.
