Abstract: Disclosed herein is a dispenser comprising an inner member including a portion having an axis and a first end closed by a transverse wall, being resiliently displaceable in the direction of the axis between a collapsed condition and a normally extended condition, and defining an interior cavity adapted to contain a substance in the form of a vapor, an outer member movable relative to the inner member with respect to the axis and including a generally cylindrical portion in closely fitting telescopic relation to the inner member and having a first open end adjacent the transverse wall of the portion of the inner member, and a second end, and a wall closing the second end of the outer member cylindrical portion, and an aperture in at least one of the inner and outer members for affording air flow therethrough relative to the interior cavity in response to displacement of the inner member portion between the collapsed and extended conditions, whereby, the application of force in the direction of the axis causes

Abstract: An air treatment system has a removable and replaceable filter, the filter having a plastic frame, and having a multi-layer filtering medium. A filter seat has a switch located along one side in contact with a flexible tab. When the filter is located in the seat and faces the desired direction, one of two projections on the top and bottom of the filter frame moves the flexible tab to activate the switch, which signals proper installation of the filter. When a filter element is installed, it starts a timer which times the service life of the filter element and an air treatment cartridge. When the timer times out, it signals a user through an LED or audible alarm to replace the replaceable components.

Abstract: An air treatment system has a removable and replaceable cartridge, the cartridge having a cylindrical plastic canister, and having a liquid-permeable vaporizing element disposed in the canister. The canister is located on one side in a cradle inside a housing where air flow is controlled between inlet and outlet ports by a pivoting frame member. A slider is moved up and down outside the housing to simultaneously move a pair of arms inside the housing into closed, partially open or fully open positions relative to the inlet and outlet ports. The canister has ports of special configuration and a baffle is placed in the canister to assist radial air flow and assure that air flows over the coiled air vaporizing element.

Abstract: A vapor dispensing system comprising a container adapted to contain a cartridge for controllably dispensing a liquid substance as a vapor, a pump for causing a flow of the vapor, conduit means for conveying the vapor flow including a first conduit communicating between the container and the pump, a second conduit communicable between the pump and the atmosphere, and means for controlling the flow of vapor.

Abstract: A device for dispensing a vaporizable material including a base adapted to support thereon an air freshener element and adapted to be supported on a pivotable door, a cover supported on the base and cooperating with the base to define an air passage communicating with the air freshener element, guide rails for affording selective movement of the cover relative to the base between a closed position wherein the air passage is substantially obstructed by a baffle and an open position wherein the device promotes passage of a flow of air through the passage during pivotal movement of the door, and detents on the base and cover which cooperate to retain the relative position of the cover and base during pivotal movement of the door.

Abstract: Disclosed herein is a dispensing device comprising a housing assembly including an outer housing including an end wall having therein an opening, a side wall extending from the end wall and terminating at an open end spaced from the end wall, a second end wall having therein an opening, and interengaging structure on the outer housing and on the second end wall for releaseably connecting the outer housing to the second end wall, an inner housing including an end wall having therein an opening, a side wall extending from the end wall of the inner housing and terminating in an open end spaced from the end wall of the inner housing and forming an opening, and a pin and socket arrangement on the outer housing and on the second end wall for supporting the inner housing within the outer housing assembly and for rotation between a first position wherein the openings in the inner housing register with the openings in the outer housing assembly, and a second position located in spaced relation to the first position an

Abstract: A dispensing apparatus comprising a container defining a chamber adapted to contain a substance to be dispensed into the atmosphere, the container including a first surface having therein a first opening communicating with the chamber, a plate member including a second surface and being secured to the container with the second surface facing and spaced from the first surface, and a valve plate including a second opening and being trapped between the first and second surfaces in sliding relation thereto for movement between a first position wherein the valve plate closes the first opening and a second position wherein the second opening is aligned with the first opening to permit the chamber to communicate with the atmosphere.

Abstract: Disclosed herein is a container fabricated of plastic and including a tubular sidewall defining a hollow interior and having upper and lower margins, an elongated flat section having parallel side edges extending substantially between the upper and lower margins, and an arcuate section extending from and between the side edges of the flat section, together with upper and lower closure members extending in telescopic relation over the sidewall upper and lower margins and closing the upper and lower ends of the sidewall, which closure members are rotatable relative to the sidewall between arcuately spaced first and second positions, and valve means including respective apertures in the sidewall upper and lower margins and in the closure members, which apertures are substantially in register, and thereby open, when the closure members are in the first position and which apertures are substantially out of register, and thereby closed, when the closure members are in the second position.

Abstract: Disclosed herein is an air freshening device comprising an upright housing including, adjacent the bottom thereof, an air inlet and, adjacent the top thereof, an air discharge, a fan in said housing intermediate the air inlet and the air discharge means for causing air flow through the housing, a filter, structure for removably supporting the filter in the housing intermediate the air inlet and the fan in the path of the totality of the air flow through the housing, a sleeve assembly within the housing for introducing into the air flow downstream of the filter a substance to be dispensed, which sleeve assembly is operable to releasably support the filter and includes relatively rotatable inner and outer sleeves, one of the sleeves defining an interior chamber, openings in the sleeves for affording valved access to the interior chamber in response to relative rotation between the sleeves, a coupling for releasably connecting the sleeve assembly and the housing, and a package of the substance to be dispensed lo

Abstract: An atmospheric control apparatus for use in a forced air ventilation duct is described having an inlet means to receive air from the inside of said duct attached to a replaceable deodorant cartridge, which is itself attached to outlet means terminating within the duct downstream of the inlet to supply an atmospheric control substance such as an odorant or deodorant into the air stream. Air flow through the cartridge is accomplished by the differential pressures present at the inlet and outlet means in the air duct.
