International Classification:

E03D009/04

US Classification:

004/20900R

Abstract:

The present invention provides a passive deodorization device housing suitable for use in a portable toilet enclosure having a vent tube for venting odors from a holding tank. The deodorization device housing includes an engagement surface for engaging a vent tube outer surface, and an aperture. Two fingers extend from the aperture into the vent tube. A retention member mounted on the fingers engage a vent tube inner surface and clamp the vent tube wall between the housing and retention member. A deodorizing element slipped into the aperture between the fingers can deodorize the malodorous vapors associated with the toilet.

Assignee:

Vaportek, Inc. - Sussex WI

International Classification:

A61L 904

US Classification:

239 58

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.

International Classification:

A01M 1900
A61L 901
A61L 902

US Classification:

422109

Abstract:

A dispenser comprising a rectangular housing defining an air inlet chamber between the first partition and the top wall of the housing, a valved air inlet communicating with the air inlet chamber, a second partition defining an air outlet chamber between the second partition and the bottom wall of the housing and a central chamber between the first and second partitions, a valved air outlet communicating with the air outlet chamber, apertures in the first and second partitions for affording air flow from the air inlet chamber, at least one tray member, a support on the end walls for horizontally supporting the tray member in the central chamber and for facilitating at least partial withdrawal of the tray member, a holder on the tray member for removably holding a plurality of relatively thin rectangular envelopes which contain a substance to be dispensed and which are arranged in parallel vertical relation to each other to permit air flow past the envelopes from the air inlet chamber to the air outlet chamber, and a blower in one of the air inlet and air outlet chambers for inducing air flow from the air inlet chamber to the central chamber and from the central chamber to the air outlet chamber.

Appl. No.:

6/174862

Inventors:

John D. Bryson - Milwaukee WI

Assignee:

Vaportek, Inc. - Milwaukee WI

International Classification:

C01F 100
C01G 1500

US Classification:

422123

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.

John D. Bryson - Pewaukee WI

Assignee:

Vaportek, Inc. - Sussex WI

International Classification:

B01F 304

US Classification:

261 52

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.
