An air freshener device (10) having a cartridge (14) and a cartridge housing (16) is disclosed. The housing (16) has a sealed first cavity (18) and a sealed second cavity (20) having a first fragrance (22) and a second fragrance (24), respectively. First and second cavities (18) and (20) have first and second opening (34) and (54) respectively. The device (10) includes a housing (12) having air passage openings (70), (76), (78), a fan (82) and power means (80) and also supports cartridge (14). When the power means (80) powers the fan (82) the air passage openings (70), (76) and (78) receive air which moves from the second (76) to the third (78) air passage opening and from the first air passage opening (70) across the cartridge (14) picking up the fragrances (22) and (24), resulting in an air-fragrance mixture which is drawn into an unobstructed air flow between the second and third air passage openings (76) and (78) and exits the third air passage opening (78), thereby allowing dispersion of the fragrance (22) and (24).

Air freshener device cartridge

An air freshener device (10) is disclosed. The air freshener device (10) includes a cartridge (12) having a housing (16). The housing (16) has a sealed first cavity (26) and a sealed second cavity (28). First fragrance (60) is located within the first cavity (26) and has a first volatility. Second fragrance (62) is located within the second cavity (28) and has a second volatility. First and second cavities (26) and (28) have first and second openings (64) and (66) respectively. First opening (64) is covered by a first removable cover (68) and second opening (66) is covered by a second removable cover (69). Alternatively, a single cover may be used for both openings. When the covers (68) and (69) are removed the fragrances (60) and (62) independently exit their respective cavities (26) and (28). The device (10) includes an outer housing (14) having a front member (70) which includes air passage openings (72). The outer housing (14) has a back member (74) adapted and configured to be mounted on a surface. Top member (78) and bottom member (80) connect front (70) to back (74). Top and bottom members (78) and (80) have openings (82) and (84) which define a slot (86) extending the length of the outer housing (14). The slot (86) is sized and configured to receive the cartridge (12) whereby when the cartridge (12) is expired a second cartridge (98) is inserted into the slot (86) proximate the top member (78) and the second cartridge (98) is moved in the slot (86) toward the bottom member (80), the cartridge (12) moves downward in the slot (86) and is forced out the bottom member (80) by movement of the second cartridge (98). The air passage openings (72) receive air which moves over the cartridge (12) picking up the fragrances (60) and (62) resulting in an air-fragrance mixture which exits the air passage openings (72) thereby allowing dispersion of the fragrances (60) and (62).

An improved scouring pad device comprises first and second bats each of which is made of a porous, fiberous, heat-weldable, polymeric material having an outer abrasive surface and an inner surface opposite the outer abrasive surface. An envelope layer of fluid impervious, heat-weldable, sheet-like polymeric material, and having outwardly and inwardly facing surfaces, lies adjacent each of the bats with the outwardly facing surface of the envelope layer confronting the inner surface of the bat. A reservoir layer of heat-weldable liquid absorbent material is disposed between the inwardly facing surfaces of the envelope layers. The bats, the two envelope layers, and the reservoir layer are welded together at a continuous closed boundary. A cleaning composition such as soap is carried in the reservoir layer and is temporarily confined between the first and second envelope layers within the boundary. Each of the envelope layers is perforated, having at least one hole therethrough, so that the cleaning composition can be released through at least one of the bats, to the abrasive surface of that bat. A method employing mass production techniques is also disclosed for manufacturing such scouring pad devices.

An improved device for dispensing a volatile substance into the environment includes a reservoir layer, having opposing first and second surfaces, for holding the substance and first and second envelope layers respectively in close proximity to the first surface and the second surface of the reservoir layer. At least a portion of at least one envelope layer is permeable to the substance. The reservoir layer and envelope layers are fused together at a first generally circular, continuous boundary at which the reservoir layer is nonpermeable to the substance to thereby define a generally circular region within which the substance is confined. The reservoir layer and envelope layers are further fused together at a second non-circular boundary completely enclosing the first boundary and the region to thereby define an outer, decorative, peripheral shape of the device. The device may also include an outer decorative layer in close proximity to at least one of the envelope layers and fused thereto at the second boundary but not at the first whereby the decorative layer has a smooth generally planar outer surface. The decorative layer may carry indicia which is resistant to deterioration caused by the substance.

A device for holding and dispensing a substance such as a liquid, paste or the like, comprises a layer of substance absorbent but heat-sealable reservoir material, for holding the substance, that has two principal surfaces. A first sheet of heat-sealable cover material is disposed in close proximity to one of the principal surfaces of the layer and a second sheet of heat-sealable cover material is disposed in close proximity to the other of the principal surfaces of the layer. The cover materials are substantially impermeable to the substance, are different from the reservoir material, and have different and higher heat sealing temperatures than the reservoir material. The sheets and the layer are compressed together at a continuous boundary at a temperature above the heat sealing temperature of the reservoir material but below the heat sealing temperature of the cover material. Therefore, the reservoir material is fused at the boundary to prevent lateral absorbtion of the fluid substance therepast and the cover material is lightly joined but not fused to the reservoir material. Therefore, the sheets may be removed from the layer to dispense the product by applying a shear force to at least one of the sheets relative to the layer. A method of making this device is also disclosed.

A battery-powered apparatus, for inducing air flow past a product capable of being vaporized, includes a compact housing that comprises a hollow outer shell and a hollow, generally cylindrical inner shell, having an axis, on which the operating components of the apparatus are supported. The inner shell is mounted with the outer shell by a hinge to pivot substantially on the axis between closed and open positions. In the closed position the inner shell compliments the outer shell to define an enclosed space and shield the apparatus components. In the open position, the inner shell is nested within the outer shell to expose the apparatus components. The product and a battery for powering the apparatus may be assembled into a cartridge formed to be received in the apparatus housing. Electrical battery contacts and a support for the cartridge in the housing are also disclosed.

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. The permeable envelope portion has a greater affinity for the substance than does the reservoir material. The remainder of the envelope comprises a material impermeable to the substance. Accordingly, the substance permeates through the permeable envelope portion to be released therefrom in vapor form into the environment.

A method of making a product, which holds and dispenses a volatile substance, comprises the steps of advancing a backing material, a reservoir material and a third material, that is permeable to the volatile substance, from respective supplies into close proximity to each other with the reservoir material lying between the backing and permeable materials. The volatile substance is then supplied to the reservoir material to be absorbed thereby. The three materials are fused together in a pattern defining a closed loop periphery to seal the reservoir material between the backing and reservoir materials at the periphery and thereby form the product.
