摘要:
A novel cigarette adapted for use in an electrical cigarette system comprising a tobacco rod having filled and unfilled tobacco rod portions and being arranged so that electrical heater elements may overlap the filled and unfilled tobacco rod portions. The tobacco rod includes a tobacco web rolled into tubular form. The tobacco web is constructed in accordance with a novel process comprising the steps of converting tobacco feedstock into a continuous sheet of tobacco web and converting the continuous sheet of tobacco web into one or more bobbins of tobacco web suitable for automated manufacture of cigarettes.

摘要:
An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.

Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.
摘要:
A cigarette filter having a reagent which chemically reacts with and removes a gaseous component of a smoke stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes from tobacco smoke. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel). The reagent can be contained in a space in the filter or incorporated in one or more filter elements such as tipping paper, shaped paper insert, mouthpiece plug, solid filter element, or free-flow filter element. The reagent can be part of or coated on paper such as tipping or filter paper or incorporated in non-paper filter elements formed from fibrous materials such as cellulose acetate or polypropylene fibers. Other preferred reagents include aminoethylaminopropylsilyl (AEAPS) silica gel and aminoethylaminoethylaminopropylsilyl (AEAEAPS) silica gel.

A filter such as an air having a reagent which chemically reacts with and removes a gaseous component of an air stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel).

摘要:
A filter cigarette is provided which is adjustable to provide a wide range of air dilution and/or RTD values and which comprises a tobacco rod, a wrapped, substantially cylindrical filter plug, and tipping paper. The filter plug comprises a first, mouth-end segment and a second, axially aligned, rod-end segment spaced apart from the first segment. The wrapping circumscribes the first and second segments defining a substantially cylindrical void therebetween which may include means of releasing varying amounts of a flavorant. The first segment is movable towards the second segment thereby compressing the plug wrap between the segments which decreases the volume of the void and increases the RTD value of the cigarette. Variable air dilution is achieved by providing at least one opening in the tipping paper and at least one opening in the underlying plug wrap positioned such that, as the first segment is moved axially towards the second segment, the first and second openings are moved into varying degrees of registry, thereby admitting varying amount of air to the filter.

The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a double layer of paper. Each layer includes calcium carbonate (i.e., about 30-40% by weight in the outer paper and about 2-15% by weight in the inner paper, the calcium carbonate in the outer paper having a surface area of about 20-80 square meters per gram by the BET method) and a burn control chemical. The outer layer also preferably includes monoammonium phosphate and sodium carboxy methyl cellulose. The calcium carbonate employed has a relatively high surface area per unit weight. The porosity of the outer layer is about 50-100 cubic centimeters per minute by the Coresta method, and may be adjusted by electrostatic perforation.
摘要:
A cigarette is provided having a variable length. A filter or mouthpiece slides within a sleeve attached to the cigarette, or a sleeve attached to the filter or mouthpiece slides over the cigarette. A single band is adhered to one element and a pair of bands is adhered to the other element. The single band is captive between the pair of bands so that the cigarette can be lengthened or shortened within the range allowed by the pair of bands, but the filter or mouthpiece cannot be removed from the cigarette. The variable length mechanism can be made to additionally provide variable dilution or variable flavorant.
