Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to cigarettes and other smoking articles, and more particularly to the amount of incomplete combustion products and side stream "tar" and odors generated when smoking. The invention relates to cigarettes that have a relatively low amount of smoke and maintain smoldering during smoking under FTC smoking conditions.

Here, the term "rFTC smoking condition" refers to performing a 2-second inhalation operation or puff (total volume: 35 mf2) with a 58-second smoldering (rest) period in between. A "buff" is a puff of tobacco smoke that is inhaled.

Common smoking articles such as cigarettes (cigarettes) have a structure in the form of a cylindrical rod and are wrapped with paper wrap to form a so-called "smokable rod". "Replenishment" refers to the contents of a cigarette or cigar, including a roll or charge of smokable material, such as shredded tobacco material (e.g., tobacco shred refill). Typically, cigarettes have a cylindrical filter element coupled in abutting relationship to a smokable rod. "Tobacco shredded replenishment material" is a replenishment material made of shredded tobacco material. Generally, the filter element consists of a tow of cellulose acetate surrounded by plug wrap and attached to the smokable rod by an outer tipping material.

Typically, a smoker lights the tip of a cigarette to burn a smokable rod and inhales the resulting smoke.
The smokable rod is usually a tobacco refill (refill made of shredded tobacco material) (also simply referred to as "shredded refill"), which the smoker inhales from the mouth end (e.g., filter end) of the cigarette. By doing so, the person inhales mainstream smoke into his or her mouth and obtains the pleasure of smoking (e.g., taste, feel, satisfaction, etc.).

During the combustion of a cigarette, sidestream smoke is generated. Sidestream smoke is smoke that is emitted directly into the atmosphere from the lit end of a cigarette. Sidestream smoke diffuses into the atmosphere and its distinctive visible characteristics and odor may be perceived and disliked by surrounding people. The relative amount of visible sidestream smoke produced by a burning cigarette is related to the amount of sidestream "tar" released from the burning cigarette. A typical commercially available cigarette with an overall length of 84 mm (e.g., a smokable rod length of about 57 mm, a filter element length of about 27 mm) that burns shredded tobacco filler typically contains about 25 mg to about 35 mg of sidestream "tar". occurs. For the method and apparatus for measuring the side stream "tar" of cigarettes, see Broctor et al., Analyst J, 1988, Vol. 113, p. 1509.

Various types of cigarettes have been proposed that are said to produce relatively low levels of visible sidestream smoke. Such cigarettes are disclosed, for example, in U.S. Pat.
No. 410, No. 4.624.268, No. 4.407,308
No. 4.231,377, No. 4.420゜002, 4
, 450.847, 4.108.151, 4,22
No. 5,636, No. 4.433.697, No. 4,461.3
No. 11, and No. 4,561.454.

In addition, various methods for modifying the composition of mainstream tobacco smoke have been proposed in the past. , No. 079,742. Additionally, tobacco replacement smoking materials with the trade names "Citrel" and rNsMJ were introduced in Europe in the 1970s.

There are also numerous prior art documents proposing smoking articles that generate flavored vapors and/or visible aerosols. Most such smoking articles use a combustible fuel source to create the aerosol and/or heat the aerosol-generating material (e.g., U.S. Pat. No. 4.71
4.082).

A smoking article capable of heating tobacco material without necessarily burning it, thereby providing the pleasure associated with cigarette smoking without producing large amounts of incomplete combustion products, is disclosed in U.S. Pat. No. 4,714,082; 4,756
, 318 and 4,793.365. Such smoking articles utilize a combustible fuel element for heat generation and an aerosol generating material that is physically separate from and in heat exchange relationship with the fuel element.

During smoking, the heat created by the fuel element volatilizes the aerosol-forming material, thereby producing an aerosol that resembles cigarette smoke. This type of smoking article has a low level of FTCr tar" emissions ("tar" emissions when smoked under FTC smoking conditions) and also has an extremely low level of visible sidestream smoke.

The present invention provides good smoking satisfaction, contains relatively little gaseous phase content in mainstream smoke, generates relatively little amount of incomplete combustion products, and is effective under FTC smoking conditions. Can be maintained smoldering, the ash produced has desirable physical properties, produces low sidestream "tar" emissions and therefore low visible sidestream smoke, and emits good flavor. The challenge is to provide cigarettes.

Accordingly, the present invention relates to a smoking article comprising tobacco material (hereinafter also simply referred to as "tobacco j") in the form of cut filler and/or in processed form.

A preferred smoking article according to the invention has two main components: (i) a roll or charge of smokable material; and (i) a roll or charge of smokable material;
i) Shaped into a cigarette with an outer wrapping material (paper wrap) surrounding the roll or charge of smokable material.The cigarette of the present invention comprises, as at least part of its smokable material, Contains smoking refill materials (materials that constitute smokable refills).

A preferred wrap material for wrapping a roll of smokable material to form a smokable rod is a paper wrap that has a low air permeability. Particularly preferred wraps with low air permeability, ie, low porosity, are those having a porosity of about 5 CORESTA units or less. The Coresta unit is a measure of the linear air velocity passing through a wrap of area 1 cm2 at a low pressure of 1 centibar. Regarding Coresta units,

Such tobacco-containing smokable material can be in the form of reconstituted tobacco and can be used as is as the only smokable material in the cigarettes of the present invention. Alternatively, the tobacco-containing smokable material may be physically mixed (blended) with other smokable materials, such as tobacco shred replenishment (replenishment consisting of shredded tobacco material), or any other They can also be used in combination in some embodiments.

It works to improve the flavor properties of. The caramelizing agent may be incorporated into the smokable replenishment material during its preparation, or may be coated (eg, as a powder) on the surface of the smokable replenishment material after its manufacture.

Examples of suitable caramelizing agents include sugars such as glucose, fructose, sucrose, etc., and compounds such as Carob Powder Code 1739J sold by M.F. Neil Inc. .

The smokable replenishment material of the present invention may be surface treated with some type of material. For example, the surface of the smokable replenishment material may be coated with a powder material. Examples of such powdered materials include cocoa powder, licorice powder, powdered minerals (eg potassium carbonate or iron oxide), tobacco powder, finely divided tobacco leaves, etc., or blends thereof. Such surface treatments can impart improved color, appearance, ash characteristics, and flavor characteristics to the smokable replenishment material.

Inorganic materials can be incorporated as fillers into the smokable filler material of the present invention. Such inorganic materials are often in the form of fibers, flakes, crystals, amorphous, hollow, or particles. Examples of inorganic fillers include calcium carbonate, calcium sulfate particles, magnesium oxide, magnesium hydroxide, perlite, artificial mica, vermiculite, clay, thermally stable carbon fiber, zinc oxide, dawsonite,
Calcium carbonate low density hollow spheres, glass spheres, glass bubbles, thermally stable carbon microspheres, calcium sulfate fibers, ceramic hollow microspheres, alumina, calcium carbonate agglomerated with carbonaceous components, low There are density-processed calcium carbonate, etc.

The smokable replenishment material of the present invention can include an agglomerated matrix replenishment of inorganic and carbonaceous components. As the inorganic component, particles of calcium carbonate, calcium sulfate, magnesium oxide, etc. can be used. A particularly preferred flocculated matrix supplement is flocculated calcium carbonate, and highly preferred is flocculated precipitated calcium carbonate. Such agglomerated matrix replenishers produce an aqueous slurry of calcium carbonate particles and binder and dry the slurry to form an agglomerated matrix of calcium carbonate (i.e., dispersed in a continuous or semi-continuous binder phase). It can be prepared by forming a matrix consisting of a large number of calcium carbonates. If desired, this slurry can also be swollen by introducing a blowing agent into it. Examples of suitable blowing agents for this purpose include linear sodium benzene sulfonates, linear alkyl sulfonates, linear alkyl ethoxy sulfonates, and the like. The calcium carbonate particles used to prepare the agglomerated matrix are described in the Journal of the American Chemical Society, Vol. 60, No. 30.
9 (1938), as measured by the Brunauer Emmetter (BET) method, typically about 20 m.
78, often less than about 10 m"78, and sometimes less than about 1 m"78. Typical binders are organic substances such as derivatives of cellulose (e.g., sodium carboxymethyl cellulose), preferably molasses, corn syrup with a high fructose content, or commercially available from M, F., Neil, Inc. Sugar-containing substances such as Carob Powder Code 1739J. Organic substances such as pectin and alginate may also be used.

The agglomerated matrix is prepared by spray drying an aqueous slurry with a high particle content of calcium carbonate and binder (e.g., a slurry containing about 40 to about 55 weight percent particles) to form agglomerated particles of calcium carbonate and binder (e.g., a slurry containing about 40 to about 55 weight percent particles). , normally spherical particles), or alternatively, such a slurry is dried by heating to form a solid agglomerated mass of calcium carbonate and binder, the solid mass of which is Particles of a desired particle size can also be obtained by crushing the agglomerates. The ratio of the amount of calcium carbonate to binder preferably ranges from about 20:1 to about 221, more preferably from about 15:1 to about 4:1 on a dry weight basis. Usually, inorganic particles aggregated with sugars or polysaccharides, when contacted with water under ambient conditions,
Sugars or polysaccharides tend to lose their cohesive properties due to their water solubility.

With this in mind, the agglomerated matrix of inorganic components and organic binder is subjected to a heat treatment. Thereby, volatile components are expelled from the organic binder and the organic binder is calcined to obtain a substantially water-insoluble, clean, combustible carbonaceous component.
The heat treatment of the aggregated matrix replenishment is carried out in a controlled atmosphere to minimize or prevent oxidation of the binder (see, e.g., U.S. Pat.
14.833), this heat treatment preferably prepares a binder in the form of a carbonaceous material, which serves as a means for agglomerating the particles of the inorganic component in the form of a matrix. Specifically, the particles of agglomerated calcium carbonate and binder are heated in an oven, batch furnace, fluidized bed, rotary calciner, belt calciner, etc., for example, at a maximum of about 6.
For example, in the case of spray-dried calcium carbonate particles agglomerated with molasses, fluidization using nitrogen gas as the fluidizing gas may be used. The particles can be heated and collected in a bed at a temperature sufficient to heat the particles from about 00°C to about 625°C. In the case of an agglomerated matrix of an inorganic component and an organic binder, the agglomerated matrix is subjected to extremely high temperatures (e.g., when the inorganic component is calcium carbonate) under conditions sufficient to avoid thermal decomposition of the inorganic component (e.g., when the inorganic component is calcium carbonate) Brief exposure to temperatures (up to about 900° C.) can provide sufficient heat treatment to sinter the organic binder. However, if the inorganic component is calcium carbonate, which undergoes some degree of thermal decomposition during the calcination process, the calcined agglomerated matrix can be removed (i) by exposure to a carbon dioxide atmosphere, or (ii) in water. It can be recarbonated by dispersing it in water and blowing carbon dioxide as bubbles into the dispersion water.

The aggregated calcium carbonate particles after this calcination step typically have a calcium carbonate content of greater than about 80% by weight, often greater than about 90% by weight, and greater than about 3% by weight.
It has a carbon content due to carbonaceous components. Typically, the aggregated calcium carbonate particles thus obtained are sieved to a US standard mesh of about -50/+325, often about -8
Particles up to a particle size of 0/+325 are obtained. Preferred calcined agglomerated calcium carbonate particles are substantially water-insoluble, spherical in shape, and free-flowing. Its bulk density is from about 0.1870 m to about 1.1 g/cm', often from about 0.3 g/cm' to about 1 g/cm, as measured by mercury permeation. Thus, the calcined agglomerated calcium carbonate particles contain an inorganic component having a bulk density greater than about 2.5 g/cm'.
The present invention provides inorganic materials having bulk densities of less than about 1 g/cm, preferably less than about 1 g/cm. Typically, such calcined agglomerated calcium carbonate particles have a surface area of less than about 30 m"/g, often between 10 m"/g and about 2 m"/g, as measured by the BET method.
It is 5m2/g.

If desired, the bulk density of the calcined agglomerated inorganic supplement can be reduced by digesting some of its inorganic components with acid. For example, by dispersing the calcined agglomerated inorganic supplement in water, Add an aqueous solution of hydrochloric acid to the slurry and stir. Acids react with calcium carbonate, but hardly react with carbonaceous components. Some of the calcium carbonate reacts to form carbon dioxide gas and water-soluble calcium chloride, and the carbonaceous component serves to hold the remaining calcium carbonate in a bound state.

Another type of filler that can be incorporated into the smokable filler materials of the present invention are low density inorganic fillers. Low density inorganic supplements are prepared by providing particles of calcium salt, decomposing the 7-ions, and contacting the particles with carbon dioxide. Examples of such suitable salts include calcium propionate, calcium succinate, calcium tartrate, calcium stearate, calcium salicylate,
Examples include calcium valmitate, calcium oleate, calcium lactate, calcium gluconate, calcium citrate, calcium asculupate, calcium acetylsalicylate, and calcium benzoate. Other suitable salts include calcium salts of m-class and polysaccharides.

Such salts are exposed to conditions sufficient to decompose their anions. The process usually involves heat treating the salt in a carbon dioxide atmosphere.

One method for preparing the low-density inorganic supplement is to sieve particles of calcium lactate to a particle size of approximately -80/+170 US standard mesh under a flowing atmosphere of carbon dioxide gas at a constant flow rate of 228 ml/min. A material is prepared which loses about 65% of its weight by heating at a temperature of about 600°C for about 8 hours, and about 20 parts by weight of the material is charged into about 80 parts by weight of water, and the resulting slurry is , contacted with sufficient hydrochloric acid solution to reduce its pH to about 6.8, the material was then removed from the water, washed with water, dried and sieved to a particle size of -180/+170. This is the way to obtain. The calcium carbonate content of the material so obtained is more than 95% by weight and the bulk density of the material is approximately 0.4 g/cm', determined by mercury permeation.

The aggregated matrix supplement can be in a form that includes inorganic and organic components. Inorganic components other than those mentioned above include calcium sulfate, magnesium oxide, magnesium carbonate, etc. Calcium carbonate aggregated using ammonium alginate is an example of an aggregated matrix replenisher having an inorganic component in the alginic acid component. It is.

Such an agglomerated matrix replenisher is prepared by preparing an aqueous slurry of calcium carbonate particles and hydrated alginate;
It can be prepared by drying the slurry to form a cohesive matrix of calcium carbonate (ie, a matrix consisting of a plurality of calcium carbonate particles dispersed in a continuous or semi-continuous alginate phase). If desired, this slurry can also be swollen by introducing a blowing agent into it. Examples of suitable blowing agents for this purpose include linear sodium benzene sulfonates, linear alkyl sulfonates, linear alkyl ethoxy sulfonates, and the like.

Preferably, or alternatively, a high particulate aqueous slurry of calcium carbonate and alginate is spray-dried to prepare aggregated particles (e.g., normally spherical particles) of calcium carbonate and alginate. It is also possible to dry such a slurry by heating to form solid lumps of aggregated calcium carbonate and alginate, and to grind the solid lumps into particles of a desired particle size. The ratio of the amount of calcium carbonate to alginate, on a dry basis, ranges from about 99=1 to about 2:1, preferably from about 20=1 to about 5:1. Calcium carbonate particles agglomerated using alginate are usually
Virtually insoluble in water. The water insolubility of the alginate in this aggregated matrix supplement greatly limits the tendency of the aggregated matrix supplement to lose its cohesive properties when contacted with water under ambient conditions. The aggregated matrix supplement is rendered water-insoluble due to the interaction of the calcium ions of the alginate and calcium carbonate. If desired, the aggregated matrix supplement is treated with a dilute solution of acid, thereby decomposing some of the calcium carbonate and releasing calcium ions, which render the alginate component of the aggregated matrix supplement water-insoluble. You can do as you like.

The agglomerated matrix replenishment material having inorganic and organic components can incorporate various other organic components other than those mentioned above. For example, the organic component can be pectin, which has the property of becoming substantially insoluble in water when it interacts with calcium ions. Alternatively, agglomerated matrix supplements having a polysaccharide organic component may be combined with divalent ions (e.g., calcium, barium, cobalt, iron or magnesium ions) or trivalent ions to render the polysaccharide substantially water-insoluble. value (e.g.
It can also be treated with iron or aluminum ions).

As yet another example, a slurry of a polysaccharide (e.g., ethylcellulose) and inorganic component particles is mixed with a non-aqueous solvent (e.g.,
The slurry can also be dried to form a substantially water-insoluble aggregated matrix replenisher.

Typically, the smokable replenishment materials of the present invention are produced by forming an aqueous slurry of an aerosol forming material, a binder, and other components of the smokable replenishment material, and casting the slurry as a sheet. It can be prepared by drying the cast material to form a relatively dry processable sheet. Techniques and equipment for casting slurries as sheets are well known to those skilled in the art. Other substances such as calcium acetate, potassium carbonate, pH control agents, urea, amino acids, potassium chloride and/or calcium hydroxide may be mixed into the slurry, and the calcium ion concentration in the slurry may also be mixed into the slurry. Sequestering agents (eg, diammonium orthophosphate-hydrogen, sodium citrate, potassium hexametaphosphate, or tetrasodium pyrophosphate) may also be incorporated in amounts sufficient to control the The slurry cast as a sheet can be dried at ambient or elevated temperatures. Additionally, the cast slurry can be coated with an aqueous solution of calcium salts. The dry sheet obtained can be cut or cut into strips and later shredded or shredded into shredded refills.

The smokable refills of the present invention can also be extruded into the desired shape using any suitable extrusion method. For details of such an extrusion process, see U.S. Pat. (e.g. an aqueous solution of calcium chloride)
Preferably, it is extruded, collected and dried. If desired, the extruded smokable filler material can be physically manipulated, eg, rolled using rollers, etc., to form the desired shape.

The smokable rods of the cigarettes of the present invention will often include a physical mixture or blend of multiple smokable materials. The blend can include at least one smokable supplement according to the invention and at least one other smokable supplement. This blend is
It may include at least two or more smokable supplements according to the invention, or alternatively, a physical interaction between at least one smokable supplement according to the invention and at least one other smokable supplement. It may include a mixture. In certain cigarettes, at least one of the inventive materials is present in an amount sufficient to cause the smokable material in one cigarette to include at least about 1% carbonaceous material, based on the total weight of the blend. Typically, such optional blends include a carbonaceous material as the carbonaceous component of the fired aggregate matrix filler. Specifically, cigarettes having such type of smokable filler material and wrapped with an outer paper wrap of low porosity (e.g., less than about 5 Coresta units) must be smoked under FTC smoking conditions. If the product has the property of maintaining smoldering between puffs (i.e., does not self-extinguish), the FTC smoking condition is to perform a puffing action (puff) of a volume of 35 ml for 2 seconds every 60 seconds. That's true.

The smokable replenishment material of the present invention can be blended with a tobacco cut replenishment material. Various types of tobacco may be used as tobacco shred supplements, such as Burle type tobacco, Maryland type tobacco, Oriental type tobacco, seeded or specialty tobacco, or blends thereof. Such shredded tobacco supplements include tobacco leaf chips, swollen tobacco leaf fragments, processed tobacco leaf stalks such as chopped rolled tobacco leaf stalks or chopped swollen tobacco leaf stalks, (i) U.S. Pat.

The reconstituted tobacco material, such as that described in U.S. Patent Application No. 414.833, filed May 29, 2006, or blends thereof, may be included.

The smokable material may be cased or topdressed in a conventional manner at various stages of cigarette manufacture. A flavoring agent can be added to the. Suitable flavoring agents include vanillin, cocoa, licorice, menthol, and the like. The smokable material may also be provided with a flavor modifier, for example, from about 0.01% to about 2%, typically from 0.1% to 1%, preferably from about 0.1%, based on the dry weight of the smokable material. Levulinic acid in amounts of 2 to about 0.6% can be applied to the smokable material as a flavor modifier. or approximately 5% based on the dry weight of the smokable material.
Calcium carbonate can be applied to the smokable material as a flavor modifier in an amount of less than 2%, usually about 2% to about 3%. Such flavor modifiers can be applied to smokable materials as casing agents and top dressings.

A preferable wrapping material for forming a smokable rod is a cigarette wrapping material (cigarette paper) having a low air permeability. Such wrap materials have an ungrooved air permeability of less than about 5 Coresta units, often less than about 3 Coresta units, and most often about 1 Coresta units. A typical wrap material is a cigarette paper wrap. be. Examples of suitable wrap materials include DD-71-1, DD-71-6, MTR-1021,
Cigarette paper wraps sold under the trade names P-2831-60-2, P-2831-60-1 and DD-100-2 are mentioned.

Also, several suitable low porosity cigarette paper wraps are commercially available, to which appropriate amounts of flammability inhibitors, fluxing agents, etc. can be added. Particularly preferred are cigarette paper wraps containing a sufficient amount of film-forming polymeric material to provide the paper with the desired low air permeability. For example, a paper wrap can be coated with a sufficient amount of an aqueous solution of a film-forming polymeric material (eg, sodium carboxymethylcellulose or ethylcellulose). Selection of the type of film-forming polymeric material will be apparent to those skilled in the art.

Such optional film-forming polymeric materials may be applied to the paper wrap during its manufacture, or
The film-forming polymeric material may be applied by printing or coating after manufacture of the paper wrap. Typically, the film-forming polymeric material is prepared in a dilute solution (e.g., about 0% in solvent) to facilitate its application operation.
．． It is applied to the paper wrap as a solution (with a concentration of 2 to about 5% by weight). The amount of film-forming polymeric material applied to the paper wrap will vary depending on factors such as the air permeability of the paper wrap and the film-forming ability of the film-forming polymeric material. Typically, the amount of film-forming polymeric material used ranges from about 1% to about 10%, based on the dry weight of the paper wrap. For example, 5% by weight of ethylcellulose in ethanol or about 5% by weight of sodium carboxymethylcellulose in water is applied to a cigarette paper wrap using a sizing applicator, the paper wrap is dried, Non-wetting, moisture-proof paper wraps can be prepared having a porosity of less than about 1 unit, preferably less than 0.5 Coresta unit.

The smokable rod of the present invention and a cigarette using the same can be manufactured in a well-known manner by a well-known cigarette manufacturing method and apparatus. Smokable rods are often
The smokable material is formed by wrapping it in a single layer of wrap material, but it can also be wrapped in two different layers of wrap material (see, for example, U.S. Patent Application No. 528, filed May 24, 1990). , No. 302).

In the case of a cigarette having a smokable rod wrapped in two different layers of wrap material, one of the low porosity paper wraps described above is used as the outer wrap of the 2N wrap material. The inner wrap can be of a variety of materials, but is typically a tobacco-containing wrap material. An example of such an inner wrap may include a paper wrap containing 3 parts Java tobacco pediole and about 1 part wood bulb. Such paper wraps are sold by Kimberly-Clark Company under the product numbers P-2249-115 and P-2831-23-3. Other suitable inner wrap materials include P-2, also from Kimberly-Clark.
540-94-A, P-2540-94-C, and P-
Sold under the product number 2540-94-D,
There are paper wraps that contain tobacco and carbonaceous materials. The inner wrap can contain a flame suppressant (e.g., potassium citrate, potassium acetate, or potassium succinate), or the inner wrap can also contain a flavoring agent (e.g., menthol or vanillin) or a flavor precursor. It can also be used as a substrate for holding bodies (eg vanillin glucoside or ethyl vanillin glucoside).

Typically, the smokable wood has a length of about 30 mm to about 70 mm, preferably about 35 mm to about 60 mm, with a length of about 17 m.
m to about 27 mm, preferably about 22 mm to about 25 mm. Short smokable rods (e.g., from about 30 mm to about 50 mm in length) can be used, especially when using smokable materials with relatively high packing densities.

"Fill density" means the weight of refill per unit volume within the smokable rod. The packing density of the smokable material wrapped in the outer wrap material can have various values.
Typical packing densities for smokable rods of cigarettes of the present invention range from about 150 mg/Cm'' to about 400 mg/Cm
m' range. Typically, the packing density of smokable rods is from about 200 mg/cm to about 380 mg/am', often about 250 mg/c, especially when using relatively short (e.g., less than 50 mm in length) smokable rods.
m3 to about 360 mg/cm'.

Preferably, the cigarette of the present invention is provided with a filter element, particularly a filter element consisting of two or more filter segments.6 Typically, each segment of a preferred filter element having two or more filter segments is approximately
It has a length of 0 mm to about 30 mm, and about 17 mm to about 27 mm.
mm, preferably about 22 mm to about 25 m, m.

The plug wrap surrounding each filter segment is typically conventional paper plug wrap and may be air permeable or substantially air impermeable.

The filter material of one of the filter segments includes a carbonaceous material (eg, activated carbon particles, charcoal particles, or carbon paper). An example of a particularly preferred filter material is P
It was prepared by pleating tobacco/carbon paper sold under the product number -144-BAC. Such filter materials reduce certain gas phase components from the mainstream smoke that is drawn into the smoker's mouth. The preferred filter materials of this segment thus serve to reduce smoke that may impart malodor or other undesirable characteristics to mainstream smoke.

Preferably, the filter material of another one of the filter segments typically comprises a fibrous material; one example of such a suitable filter material is a shirred nonwoven web of polypropylene. A particularly preferred nonwoven sheet web of polypropylene is that sold by Kimberly-Clark Company under the product designation PP-100-F. Another example of a suitable filter material is cellulose acetate tow. Particularly preferred cellulose acetate tows include (i) a tow of cellulose acetate of about 8 denier per filament, totaling about 40,000 denier; (ii) about 8 denier per filament.
denier, totaling about 15,000 denier tow of cellulose acetate; (iii) about 8 denier per filament, totaling about 25. Cellulose acetate tow of O○○ denier; (iv) cellulose acetate tow of about 8 denier per filament, totaling about 30,000 denier. A plasticizer such as triacetin, propylene glycol or triethyl citrate can be combined with the above filter material.

Yet another filter segment comprises a shirred web of non-woven thermoplastic (i.e., hydrophobic) fibers in intimate contact with a water-soluble tobacco extract to constitute a tobacco extract-containing filter material. A particularly preferred nonwoven web is a nonwoven web of polypropylene fibers sold by Kimberly-Clark under the product designation PP200 SD. Examples of such filter segments and filter elements include: 198
U.S. Patent Application No. 414.835, filed September 29, 1990 and U.S. Patent Application No. 518.59, filed May 3, 1990.
It is stated in No. 7. Such a filter segment can enhance the flavor characteristics of mainstream smoke passing through it.

As a further filter segment, a filter material consisting of tobacco paper (paper made from tobacco wood) can be used. For example, such a filter material is available from Kimberly-Clark under the product number P-144-B. It may consist of a rolled web of tobacco paper sold at.

Filter segments of filter elements suitable for use in the present invention can be manufactured using well-known cigarette filter manufacturing methods and equipment.

For example, filter elements can be manufactured from cellulose acetate tow using well-known techniques. Filter elements can also be made from carbon paper, tobacco paper, or sheet-like nonwoven polypropylene webs using the filter manufacturing method described in U.S. Pat. No. 4,807,809. Alternatively, a third segment of charcoal or activated carbon particles may be interposed between two segments of suitable filter material, thereby creating a so-called "triple" filter element. .

The filter element can have low, moderate, or high filtration efficiency (mainstream smoke removal efficiency) as desired, but the mainstream aerosol (i.e., smoke) removal efficiency is as low as possible and Filter elements with desirable suction characteristics of , and those with low mainstream smoke removal efficiency are so-called "low efficiency" filters. A low-efficiency filter has a small ability to remove particulate matter from mainstream smoke. Regarding the mainstream smoke removal efficiency of the filter element,

Typically, the tipping material surrounds the filter element and a portion of the smokable rod adjacent thereto and extends from about 3 mm to about 6 mm along the length of the smokable rod. The tipping material is typically a conventional paper tipping material. As the chipping material, materials having various porosity can be used.

For example, the chipping material may be substantially air impermeable, or it may be air permeable, or the chipping material may be perforated to provide an air dilution means. In order to control the performance characteristics of the cigarette of the invention, the total area of the perforations and the circumference of the cigarette can be perforated to form openings or air holes, for example using mechanical or laser techniques. The arrangement of perforations along the surface can be varied.

In the case of the air diluted cigarettes of the present invention, the amount of air dilution can be varied. Typically, the amount of air dilution in air diluted cigarettes is about 25% or more, often about 40% or more. be. The upper air dilution limit for cigarettes is usually less than about 75%, often less than about 65%. "Air dilution" here refers to the ratio (usually expressed as a percentage) of the amount of air drawn through the air dilution means to the total amount of air and aerosol (smoke) drawn through the cigarette and flowing out from the mouth end of the cigarette. expressed).
