A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with an optional burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and an optional burn suppressing agent. Alternatively, a smokable rod possesses a single blend of smokable materials; at least a portion the smokable material being a tobacco material carrying a relatively high amount of aerosol forming material; and optionally at least a portion of the smokable material being in intimate contact with a burn suppressing agent. A filtered cigarette can be produced by attaching a filter element to one end of any of those smokable rods.

A smoking article such as a cigarette comprises a tobacco rod and a filter component having a cavity filled with spherical beaded carbon. As mainstream tobacco smoke is drawn through the filter component, targeted gas phase smoke constituents are removed as the smoke passes through the carbon. During the filter manufacturing process the spherical beaded carbon flows like a liquid and substantially completely fills the cavity. Point-to-point contact between the spherical beads together with substantially complete filling of the cavity produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads during smoking.

A battery powered portable human body carrying electronic human breath filtration device is an electronic nose mask and is the most ideal alternative to conventional filter paper type nose mask. It utilizes electronic ionization technique and electrostatic field to remove air borne particles, dust, pollens, contaminants, bacteria, viruses, toxic chemical, fume and tobacco smoke from human inhalation and exhalation breath. It interacts with human breathing action as the air flow driving system to move the inhalation and exhalation breaths through the electronic filter elements, in addition to a front louver cover and a rear louver cover's protection as pre-filters. The system requires very low running current and uses small batteries usually found in household electronics. This filtration system is light weight with negligible air flow resistance and is integrated into the nose mask which is connected to a pocket size control system via a connection cable.

Improved filters useful for tobacco products, such as cigarettes, and novel cigarettes having such filters are disclosed. The filters include adsorbents such as activated carbon which reduce amounts of one or more gas phase constituents of mainstream tobacco smoke. The adsorbents are treated with off-taste suppressants which reduce the off-taste associated with adsorbent containing filters and substantially restore the taste normally associated with tobacco smoke.

A filter such as a cigarette filter having a metal reagent which selectively binds with a gaseous component of a gas stream such as tobacco smoke. The metal reagent comprises nanometer or micrometer size clusters of a transition metal or alloy containing a transition metal. The transition metal can be incorporated in an intermetallic compound such as titanium aluminide or iron aluminide. The metal clusters can be incorporated in or on a support material such as silica gel, porous carbon or a zeolite. The metal reagent can remove the gaseous component by selectively binding to unsaturated hydrocarbons such as 1,3-butadiene. The binding can occur by insertion of a metal atom of the metal reagent into a C—H bond or a C—C bond of the gaseous component.

A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with a burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit, and the tobacco cut filler of the inner core burns to yield tobacco smoke. The outer material smolders, and hence thermal decomposition products of the outer tobacco material and volatilized aerosol forming material are produced. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and a burn suppressing agent.

The invention discloses a method for predicting the main indexes of flue-cured tobacco smoke, which comprises the following steps: firstly, establishing a model for the main indexes of the flue-cured tobacco smoke; secondly, detecting the main chemical compostions and the main indexes of the smoke of a training flue-cured tobacco sample and a testing flue-cured tobacco sample; thirdly, using a gray function clustering method to cluster the training flue-cured tobacco sample; fourthly, determining the variable of the sample entering the model; fifthly, establishing a gray prediction model between the main indexes and the main chemical compositions of the smoke of each type of the sample; sixthly, establishing a BP neural network for each type of the training sample; and seventhly, performing a test and an adjustment by using the main indexes and the main chemical compositions of the smoke of the testing flue-cured tobacco sample. In the process of detection, the main chemical components of the flue-cured tobacco sample to be tested are clustered; and then the model of the type of the sample is applied to performing prediction so as to obtain the main indexes of the smoke. The method overcomes defects that the prior art needs to detect and operate a large number samples, achieves the prediction of the main indexes of the flue-cured tobacco smoke by using a small amount of the chemical composition samples, lightens the workload caused by smoke panel tests for formulating personnel, and can be widely used in the tobacco industry.

This invention is an improved method for controlling, reducing, and quitting smoking. Specifically, this method requires the use of one or more non-combustible devices that employ (at least) (A) a loading chamber for measuring the amount of combustible material to be smoked; and (B) a baffle or similar apparatus to prevent the smoker from inhaling the tobacco. By using one such non-combustible device, the smoker can measure the precise amount of tobacco to be smoked. Hence, the smoker can reduce his or her dependency on smoking by limiting the amount of tobacco smoked, as well as how many times he or she smokes that amount each day. By using two or more non-combustible devices with varying loading chamber lengths, the smoker can reduce his or her dependency by gradually reducing the amount of tobacco smoked, in addition to how many times he or she smokes a day.

The present invention is a capsule that has a perforated outer shell that is substantially filled with a filtering media which has been pressurized to remove air pockets resulting in more effective and consistent filtration. The media may be activated carbon or other filtering media and may include other flavorants, aromatic substances, or a combination thereof. The present invention, thus, also provides an insert for a smoking article. The insert is the capsule of the present invention, namely, a perforated shell with media filling the cavity (without “air pockets”) formed by the shell. The capsule is placed within the smoking article at a point between the tobacco and the point of inhalation (the mouthpiece) such that, upon inhalation, the tobacco smoke is drawn completely and consistently through the media. Alternatively, the capsule may be integrated into a cigarette holder, pipe, or the like at a point in-line between the tobacco charge and the smoker.
