Pocket-size container for consumer items
Patent 7,878,324
A three-piece pocket-size container for holding a consumer product such as smokeless tobacco product in an interior volume of a perimeter band which has a base locked to a lower rim portion [private] and an openable cover on an upper rim of the perimeter band. When closed, the cover, the perimeter band and the base form a flush exterior sidewall of the container. The base and cover can be metal and the perimeter band can be transparent (clear, tinted or colored) or opaque plastic to provide a container that maintains product freshness, and is easily opened and closed.

Cigarette gas filter

Patent 7,874,296
Cigarette gas filter is used to filter the gaseous components of main stream smoke. This causes reduction of the delivery of the gaseous constituents of main stream smoke (MSS). The gas filter consists of a narrow annular gap, where the outer side is circumvented by a high permeability wrapper paper. As the cigarette smoke is passed through this annulus gap, the fraction of gases present in the smoke is reduced by diffusion mechanism and due to inflow of air into the annulus by convection mechanism. Since the diffusion coefficient of aerosol particles are several orders of magnitude smaller than the gas molecules, the aerosol particles are kept mainly intact while passing through the annulus. Therefore this filter is applied for reducing the gas/tar ratio. This filter can also be used to filter the gases of non-cigarette smokes.

Tobacco powder supported catalyst particles

Patent 7,878,211
Cut filler compositions, cigarettes, methods for making cut filler compositions and cigarettes, and methods for treating mainstream tobacco smoke of cigarettes are provided that use catalyst particles capable of converting carbon monoxide to carbon dioxide. The catalyst particles are supported on tobacco powder. The tobacco powder supported catalyst particles can be prepared by dry admixing the catalyst particles and tobacco powder or by combining a dispersion of catalyst particles with the tobacco powder.

Cigarettes and filter subassemblies with squeezable flavor capsule and methods of manufacture

Patent 7,878,962
Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

Palladium-containing nanoscale catalysts
Patent 7,879,128
A method of making palladium-containing nanoscale catalyst particles comprising subjecting a starting material to laser energy so as to form a vapor and condensing the vapor so as to form the catalyst particles. The catalyst comprises nanoscale particles of palladium and/or palladium oxide incorporated in and/or on nanoscale particles of a metal or metal oxide. The nanoscale catalyst, which can be incorporated in the tobacco cut filler, cigarette wrapper and/or cigarette filter of a cigarette, is useful for low-temperature and near-ambient temperature catalysis. The nanoscale catalyst can convert carbon monoxide and nitric oxide that are found in mainstream smoke to carbon dioxide and nitrogen, respectively. The nanoscale catalyst may also be incorporated into a hydrocarbon conversion reactor, into a vehicle exhaust emissions system, into a laser, into a fuel cell or used in an air filter or for emissions reduction in the cold starting of an automobile engine.

Cellulose acetate fiber modification

Patent 7,878,210
Cellulose acetate fibers can be modified to have physical imperfections and then incorporated into cigarette filter plugs as filtering materials. Cellulose acetate fiber modification can be achieved by etching with a gas phase etchant or a liquid phase etchant comprising hydrogen peroxide. Modification of cellulose acetate fibers may be performed at various stages during the manufacture of cigarette filter plugs. Furthermore, cigarette filter plugs containing modified cellulose acetate fibers can also have spaced apart slits along the length of the cigarette filter plugs.
