    Abstract: An air freshener canister includes a container, a nipple thereon and a cap threadably matable therewith. The cap can be positioned along the length of the nipple from a closed position with the cap rim against the exterior surface of the container and an open position wherein there is spacing between the rim and exterior surface. A volatile liquid in the container emits air freshener vapors. A wick runs from the liquid to the nipple. When the cap is in the open position, vapors escape from the wick through the spacing. When the cap is in the closed position the vapors are prevented from escaping. When the cap is removed from the nipple the container may be refilled with the volatile liquid. The escape of vapors may be increased or decreased by positioning the cap on the nipple to increase or decrease the spacing.

  • Patent number: 6197262
    Abstract: A device (1) for the depuration and sanitization of air comprising a tank (10) divided into at least two compartments (17-18) containing suitable liquids into which penetrate the lower parts of relative groups of perforated discs (21) arranged, suitably spaced one from the next, on a shaft (20), placed horizontally and set at its ends onto supports (131-141) obtained centrally on the transverse walls (13-14) which are at the extremities of the tank (10) and connected at one end to a geared electric motor (40). The upper parts of the perforated discs (21) are housed in a semicylindrical casing (30) in which they are traversed by the air drawn in by means of a fan (7). The liquids inserted into the compartments (17-18—etc.) of the tank (10) consist of a basic aqueous solution, with the addition of a surfactant and eventually antifoaming agents, to which can be added quaternary ammonium salts and/or organic salts whose adsorbing action allows also the sanitization of the treated air.

  • Patent number: 6123935
    Abstract: This invention provides an air freshener dispenser device comprising (1) a disposable air freshener cartridge which has an affixed electrical-resistance heating element on its upper section surface, and (2) an electrical plug housing. The cartridge has an elongated thermoplastic hollow body configuration with a sealed internal reservoir chamber of liquid air freshener medium, and the upper section of the cartridge body is shaped to a flat shallow extension of the cartridge chamber. A thin wick matrix extends internally from the cartridge chamber bottom up to the top of the chamber shallow extension. The cartridge has an integrally structured means adapted for removal of a top portion of the cartridge chamber shallow extension to expose an upper section of wick matrix to the atmosphere. The electrical plug housing is detachably secured and positioned proximate to the cartridge heating element. Activation of the heating element promotes air freshener dispersion into the atmosphere from the exposed wick.

  • Patent number: 6045055
    Abstract: The present invention is directed to a device for delivering a fluid to the surrounding environment. The device includes a housing having an interior region and at least one opening, a fluid contained within the interior region, and a device means to force the fluid through the opening, and against gravity. Such a forcing device preferably comprises a gas generating pump, designed to force fluid positioned below the opening through a channel or conduit and out of the housing. Moreover, the opening in the housing may be associated with a member for controllably releasing fluid from the housing, for instance one or more porous plugs, an emanator pad, a decorative element or an adjustable valve. Additionally, the invention contemplates the use of a moveable member, such as a piston, flexible bladder, or expandable bladder, to separate the fluid from the gas generating pump and assist is forcing fluid out of the housing.
