International Classification:

A61L009/12

US Classification:

422 4, 422 5, 422123, 239 58

Abstract:

A dispenser for controlling the release of volatile materials within a contained environment such as an automobile, a home, an office, a factory, or the like, comprises a housing having an opening therein, a volatile material positioned within the housing, and a temperature responsive component in operable association with the opening to regulate said opening in order to contain or release the volatile material. The temperature responsive component automatically controls the release of the volatile material in the contained environment in response to a change in the ambient temperature by uncovering or covering the opening of the housing. A method for controlling the release of volatile materials within a contained environment is also disclosed.

Assignee:

Bush Boake Allen, Inc. - Montvale NJ

International Classification:

B65D025/08

US Classification:

206219

Abstract:

The present invention is directed to a compartmentalized storage system for temporarily storing and subsequently mixing at least two different substances. The compartmentalized storage system comprises a first storing compartment, with an optional a tearable seal, containing a solid sorbing substrate, such as a wipe, and a first substance. The compartmentalized storage system further comprises a second storing compartment having a second substance. The first and the second compartments are attached to each other by at least one common side, which common side comprises a frangible seal connecting the first and the second compartments. By applying force to the frangible seal, the seal will break and thereby allow the second substance in the second storing compartment to be mixed with the solid sorbing substrate and the first substance in the first storing compartment.

Inventors:

Randall G. Richards - Cincinnati OH

Assignee:

The Drackett Company - Cincinnati OH

International Classification:

E03D 902

US Classification:

4228

Abstract:

An in-tank dispenser adapted to dispense a disinfectant solution when the toilet is flushed, the dispenser comprising a product chamber having a lower section and an upper section in fluid communication and containing a disinfectant material that releases gaseous material in aqueous solution, there being a shoulder at the interface of said sections, the cross-sectional area of the lower chamber in the plane horizontal thereto being larger than that of the upper chamber; an inlet/outlet pathway in the form of an inverted U-shaped conduit having an exterior leg and an interior leg, the uppermost portion thereof wherein the legs are joined being arcuate in shape and having a volume of less than about 0. 50 cubic centimeter, said conduit being in fluid communication at the shoulder of the product chamber, the cross-sectional area normal to flow of the interior leg being less than that of the exterior leg; and vent means proximate the top of the upper section of the product chamber. The disinfectant may be selected from the group consisting of halogenated hydantoins, trichloroisocyanuric acid, and inorganic hypochlorite salts of calcium, lithium and magnesium.

E03D 903

US Classification:

4228

Abstract:

The present invention provides a passive dispenser for use in a toilet tank in which the solution to be dispensed is isolated from the water in the toilet tank. The dispenser comprises of internal reservoir for storing a quantity of the solution, an upper venting means having passive means to provide an upper air-lock, and discharge/refill conduit disposed below the upper venting means, the conduit comprising an air trap chamber and an air refill chamber connected by a transfer port so as to provide a lower air-lock for isolating the solution from the water in the toilet tank.

Inventors:

Randall G. Richards - Cincinnati OH

Assignee:

The Drackett Company - Cincinnati OH

International Classification:

E03D 902

US Classification:

4228

Abstract:

A passive dispenser for containing a quality of solution isolated from a body of liquid and for causing a predetermined volume of said solution to issue from the dispenser solely under conditions of gravity flow in response to the level of said body of liquid being lowered from a first elevation to a second elevation, said dispenser adapted for placement at the bottom of said body of liquid, comprising an upper section which is a cuplike member having an open bottom, the lower peripheral edge being an annular channel; a lower section which is a cuplike member having an open top, said cuplike members providing an internal reservoir for storage of cleaning solution formed upon dissolution of a water-soluble cake contained with said reservoir, the top peripheral edge of the lower section being disposed within said annular channel to define a discharge/refill conduit connecting said reservoir with the body of liquid and comprising two chambers in fluid communication with each other, one chamber being adjacent to said reservoir to form an air trap chamber and the other being adjacent to said body of liquid to form an air refill chamber, a transfer port connecting said air trap and air refill chambers, the cross-sectional area of said transfer port normal to fluid flow being smaller than the cross-sectional area of said air trap chamber normal to fluid flow such that air in said conduit is not completely displaced by said liquid when the level of the body of liquid rises from said second elevation to the first elevation, the air being entrapped in said air trap chamber and forming, upon cessation of flow into the reservoir, an air lock in said conduit that substantially isolates said solution from the body of liquid; and vent means above the discharge/refill conduit for air to vent from said reservoir.

Abstract:

A passive dispenser adapted for placement in a body of liquid for codispensing a first solution and a second solution in response to a lowering of the level of the body of liquid from a first elevation to a second elevation, the dispenser comprising a first chamber for storing said first solution having an inlet/outlet pathway comprising an interior conduit and an exterior conduit adapted to discharge said solution by siphon flow and further having a vent conduit extending to the atmosphere, and a second chamber for storing said second solution having a refill/discharge pathway comprising a conduit adjacent the chamber and a conduit adjacent the body of liquid and further having venting means, the refill/discharge pathway and venting means being adapted to isolate said second chamber from the body of liquid by means of the formation of air locks.
