Abstract: Air freshener apparatus comprising a cup-like base in which a quantity of fragrance emitting ingredient is disposed in at least a partially exposed relation. Secured air sealed about the support is a tubular bellows a soft, pliable composition forming an air chamber overlying the exposed relation of the fragrance ingredient. Breather holes formed through the support underlying the fragrance ingredient therein enables dispensing of a controlled quantity of fragrance scent by manually compressing the bellows. An adhesive pad on the undersurface of the support enables the apparatus to be attached to a recipient surface. Merchandise packaging of an air freshener unit includes a blister wrap of pliable composition having an aperture communicating from inward to outward thereof. This enables on-site consumer testing of the unit by depressing the wrap which in turn compresses the bellows to effect a scent emission outward through said aperture.

Abstract: A fragrance emitting unit which when hand actuated expels into the atmosphere a pulse of fragrance. Included in the unit is an air-filled container provided with a small jet opening, the container having a flexible wall which when depressed subjects the air in the container to pressure to cause a pulse of air to be expelled through the opening. Interposed between the jet opening and the interior of the container is an air-permeable, porous member impregnated with liquid fragrance whereby when the unit is first actuated, a pulse of air is forced through the member to extract fragrance therefrom to produce a fragrance mist that is discharged through the opening. When the wall is then released and seeks to resume its normal state, the resultant vacuum created within the container causes air to be drawn into the jet opening and to be forced through the member into the interior so that the charge of air in the container is now laden with fragrance.

Abstract: Fragrance dispensing system and process are provided by separately utilizable dispensing apparatus and a source of fragrant dispersant. The dispensing apparatus is charged and recharged by use of the source of aerosol dispersant.

Abstract: A device for both instant and continuous dispensing of an air-treating composition. The device has a pressurized vessel with a valve stem, an actuator-overcap, and an absorbent member adjacent to vented actuator-overcap walls. The actuator-overcap, which is preferably a single integrally-molded piece, has an actuator button and a channel member engaged with the stem and terminating in a spray orifice. The channel member and/or the valve stem have outlets for directing liquid onto the absorbent member, and the spray orifice, outlets and liquid passageway are configured such that the rate of discharge onto the absorbent member exceeds the rate of spray discharge into the air, preferably by more than 2:1.

Abstract: An apparatus is provided for dispensing volatile substances which includes a housing, and at least one piezoelectric blower. Each blower includes a piezoelectric element having a first end mounted to the housing and a second end free, and a generally planar impeller blade connected to the free end of the piezoelectric element and having its distal end unconstrained by the housing. A frame is attached to, or provided as an integral part of, the housing and is located in proximity to the distal end of the blade. The frame is adapted to detachably mount a replaceable substrate cartridge containing a volatile substance. In use, a voltage is applied to the piezoelectric element for oscillating its free end perpendicular to its plane at or close to resonance and propagating a traveling wave along each blade to generate and shed vortices at the distal end of the blade which contact the substrate cartridge, thereby dispensing the volatile substance to the surrounding atmosphere.

Abstract: A fragrance dispensing device to provide a fragrance or scent by direct or indirect means comprising a container to discharge a quantity of a suitable fragrance, such as a perfume or deodorizer, and a cover assembly for the container to permit direct discharge in the form of a spray of the fragrance or scent and also to confine the spray discharge within the cover assembly where it is absorbed or adsorbed on a carrier member so that the fragrance or scent may be dissipated over a longer period of time.

Abstract: A combined spray and evaporative air freshener or the like device which comprises a generally cylindrical ornamental shroud open at one end and having an apertured top, for application to a conventional aerosol spray container having a manually depressible valve for actuating the same. The top of the shroud has an interior bottom opening cup which in general surrounds the actuator for the valve and receives the spray upon depression of the valve stem, the spray falling in droplets into the valve cup.An impregnated absorptive ring may be placed in the cup in position to be impinged upon by the spray in situ, the impregnated material being activated by the spray when the shroud is depressed, releasing additional fragrance into the air. The ring may also be placed in the usual valve cup surrounding the valve and in this case it is activated by the spray material dripping on it.

Abstract: An aerosol container is provided for foaming a liquid aerosol composition therein prior to expulsion from the container and then expelling the resulting foamed aerosol composition comprising, in combination, a pressurizable container having a valve movable between open and closed positions, with a valve stem and a foam-conveying passage therethrough in flow connection with a delivery port; at least two separate compartments in the container, of which a first compartment is in direct flow connection with the valve passage, and a second compartment is in flow connection with the valve passage only via the first compartment; and a porous bubbler having through pores interposed between the first and second compartments with the through pores communicating the two compartments, the pores being of sufficiently small dimensions to restrict flow of propellant gas from the second compartment therethrough and form bubbles of such gas in liquid aerosol composition across the line of flow from the porous bubbler to the v
