    Abstract: The present invention is directed to a device for releasing a volatile substance. The device includes a housing having an interior region, a volatile substance contained within the interior region, and the ability to controllably release the volatile substance from the housing. Such controllable release can be accomplished by the housing being substantially permeable to ambient air, yet substantially impermeable to the volatile substance contained within the interior region of the housing. Additionally, the invention contemplates the use of one or more porous plugs for diffusing the volatile substance therethrough and eventually into atmosphere in a vapor form. To assist such diffusion, the invention likewise contemplates the use of an electrochemical gas generating cell, a heating element and/or other features which allow air to controllably enter into the interior region of the housing.

  • Patent number: 5810253
    Abstract: A device for the controlled dispensation and unattended evaporation of volatile liquids includes a housing that accommodates a reservoir charged with a volatile liquid. The reservoir has an outlet for releasing the volatile liquid from a lower end of the reservoir. A valve mounted on the reservoir controls the flow of the volatile liquid through the reservoir outlet. The valve allows a controlled quantity of the volatile liquid, in the form of discrete droplets, to be gravitationally delivered, on demand, to an absorbent matrix. A matrix housing supports the matrix below the reservoir outlet. The absorbent matrix absorbs volatile liquid that the outlet delivers and dispenses the volatile liquid as a vapor to an external environment. The absorbent matrix dispenses the vapor via a ventilator that may be either releasably or integrally mounted to either the matrix housing or the housing that accommodates the reservoir.

    Abstract: A passive aromatic substance dispenser is described. A highly absorbent rod shaped wick, held within a hermetically sealed tube, serves as a fragrance dispensing reservoir in contact with an efficient fragrance diffuser, and also serves as a convenient means for suspending the diffuser in a selected area to be fragranced. When fragrancing an area is not desired, closing the housing for the diffuser seals the diffuser from ambient air currents, protecting the aromatic substance from evaporating from the diffuser. The vacuum that develops within the tube due to the absorption of aromatic substance from the rod and into the diffuser prevents draining of the fragrance material from the rod and into the diffuser when not required, thus providing self regulation of the fragrance material by the dispenser.

  • Patent number: 5314669
    Abstract: A new and improved method and apparatus are presented for freshening the air. The device comprises an inner cylindrical member with vents, with a retaining carriage which is capable of housing at least two separate and distinct scented media, and an outer cylindrical member with vents. The inner cylindrical member is concentrically retained within the outer cylindrical member and can be rotated to achieve different alignments of the vents in the inner and outer cylindrical members. The device enables two or more separate and distinct scented media to interface with the air and thereby disperse their scent either in the alternative, thereby enabling the dispersal of different scents without changing the media within the retaining carriage, or at the same time, thereby creating a new and distinct scent due to the multiple air interface of the scented media.

  • Patent number: 5265749
    Abstract: A container wherein a top member and a base member are formed as identical units, e.g., from a common mold, and have interactive shapes that permit the top to be laid upon the bottom in a nesting, closed configuration, and rotated relative to the bottom to one or more open configurations with at least three points of engagement whereby the size of the openings therebetween are varied in the different open positions and allow for movement of ambient air therebetween. The top cover and base, formed with identical common interfacing areas, can be subsequently modified, e.g., decorative or ornamental components can be added to the other, non-interfacing areas. Additionally, a handle could be added to the top cover. A pedestal could be added to the base. In a preferred embodiment, each member has a curvilinear outer periphery.

  • Patent number: 5238657
    Abstract: Nozzles are provided for spraying a wetting medium into the gas flow in an activating reactor. The nozzle comprises a nozzle body having a plurality of nozzles The nozzle body is surrounded by a flexible and/or porous casing and a conduit introduces a gaseous medium into the casing. The gas can be introduced in either pulses or continuously. The gas introduced in pulses causes the casing to change its form and, where a perforated or porous casing is used, the continuous gas flow forms a protective gas film around the casing, thus removing the solid material accumulated on the casing.

  • Patent number: 5180107
    Abstract: Described is a dispensing unit of a volatilizable substance capable of visible determination of its extent of use. The unit has a variably located centroid initially positioned proximate the geometric center point of the unit with the centroid moving downward when the unit is in use. As the volatilizable substance evaporates, a weight eccentrically located in the same place as the volatilizable substance angularly rotates about the "z" axis leaving its upper position and finally coming to rest at a lower position when the volatilizable material is used up. At least the final position is rendered visibly detectable by means of a simple sighting mechanism.
