The present invention relates to Smoking articles with smoked Nacional material as a substitute for tobacco, and the method of regulating the speed of combustion in the static mode.

In recent years, had spent a lot of effort to find various substitutes tobacco smoked nekinoshnyh materials with low content of biological matter, the combustion of which during Smoking causes many problems related to health and the smoker and the people around him. Currently, there are a large number of different substitute tobacco Smoking materials or alternative Smoking materials. One of the drawbacks of these alternative tobacco materials is the difficulty of regulating the combustion process associated with a reduced content of combustible substances. To adjust the burning speed to substitute tobacco Smoking materials necessary to add certain well-known properties of combustion, in particular combustible additives, such as organic acid salts with alkali metals, sodium acetate (as proposed, in particular, EN 2045209) or potassium, or flame retardants, such as calcium chloride or magnesium. In WO 97/32490 it is proposed to use in Smoking products smokable material containing as a binding whom Ananta extract combustible substance from the corresponding source.

In the US 4109664, WO 96/07336 and EP 0419975 described Smoking materials with inorganic fillers (sometimes agglomerated according to EP 0419975), binder and aerosol forming substances. However, none of these documents do not have any information about the effectiveness of the proposed Smoking products materials part of the transfer to the smoke aerosol forming substances compared to conventional cut tobacco. These documents do not even consider the possibility of transfer of the increased amount of aerosol forming substance and diluting them inhaled by the smoker smoke. Thus, in particular, in the examples in the patent US 4109664, the amount of glycerin in the smoke is not more than 4% of the total number of glycerol contained in the proposed in this patent the Smoking material. In addition, none of these documents there is no information about the particle size of the inorganic filler, nor about the possibility of changes in the rate of burning in the static mode and/or properties of the ash generated by the combustion of the particulate Smoking material contained in such inorganic fillers. In addition, such a Smoking material has poor processability, in particular, has increased fragility, significantly complicating the molding of the sheet it Smoking material.

One problem which the present invention is to provide a Smoking material, the use of which in the Smoking product provides a more efficient transfer of aerosol forming substances in the smoke as compared with Smoking material with conventional cut tobacco treated with the same amount of aerosol forming substances. Proposed in the invention of the Smoking material has a high transfer efficiency aerosol forming substances in the smoke, which is 40% more than the Smoking material containing only conventional cut tobacco.

In addition, the present invention features a Smoking material with non-combustible inorganic filler, the particles of which have an optimum size and improve parameters of combustion of the Smoking material.

Accordingly the present invention was based on the task of developing a Smoking product proposed in the invention of the Smoking material, formed in the area where the main stream smoke contains a smaller number of components compared to conventional Smoking products.

Another object of the invention consisted in the development of Smoking articles containing the core of the proposed invention the Smoking material and filter tobacco smoke, which significantly reduces the content in the main stream smoke of certain components of the crack is about material, such as carbonyl compounds, or hydrogen cyanide, and different due to the use therein of a rod of the proposed Smoking material and filter significantly less than regular tobacco products, content in the main stream smoke of certain components of the Smoking material.

Another object of the invention consisted in the development of Smoking articles, the Smoking of which is allocated a relatively small number of typical tobacco carcinogenic nitrosamines.

The invention consisted in the development of Smoking material, the use of which in Smoking products can improve the taste and aroma of smoke and improve slidenote ash.

Another object of the invention consisted in the development of a method for controlling the amount of smoke inhaled by a smoker when one finger in the process area of the product proposed in the invention of the Smoking material.

In addition, the invention consisted in the development of the method of controlling the speed of combustion in the static mode crack material having a specific composition.

The present invention offers a Smoking article with the wrapped rod of smokable acinacea material composed of a mixture comprising a Smoking material status is of ASI from non-combustible inorganic filler, alginic binder and aerosol forming substance, and the total amount of these three components exceeds 90 wt.% in terms of the weight of the Smoking material. When this Smoking product is a measure of transfer efficiency aerosol forming substances in the smoke, more of 4.0.

Thus, non-combustible inorganic filler, a binder and aerosol forming substance are the main components of the proposed invention the Smoking material and eliminates the need for the presence of, for example, extract combustible substance as its essential component. In a preferred embodiment, the content of these three components in total may be more than 90 wt.%, most preferably about 94 wt.% or higher, calculated on the weight of all Smoking material. In principle, the entire proposed in the invention of the Smoking material may consist of only three of these components.

As other components of the Smoking material you can use dyes, cellulose such as wood pulp, or flavorings. Professionals in this field are well known and some other components of the Smoking material, which usually add to it in small quantities. From the foregoing it follows that the nomenclature of the components of the sheet crack materialising small.

In the context of the present description, the term "Smoking material" means any material that can be used in the Smoking product. Obviously, there is no need to say that this material should be flammable. Usually Smoking material made in the form of a sheet, which is then appropriately cut. After cutting Smoking crushed material can be mixed with other components used in the manufacture of Smoking products.

According to the invention, the transfer efficiency of aerosol smoke is measured by a percentage of the aerosol content of the smoke content in the Smoking material and preferably has a value greater than 5, more preferably greater than 6.

Smoked naconechny material may be a mixture containing proposed in the invention of the Smoking material is not more than 75 wt.%.

The content of the inorganic filler in the Smoking material should preferably be from 60 to 90%, more preferably more than 70%. The amount of inorganic filler should preferably be about 74 wt.% in terms of the weight of the finished sheet Smoking material, but can reach 80, 85, or 90 wt.% in terms of the weight of the finished sheet Smoking material.

In the proposed invention the Smoking material, the average particle size of the inorganic filler preferably ranges from 400 to 100 μm, more preferably greater than 125 μm, most preferably greater than 150 microns. In a particularly preferred embodiment, the average particle size of the inorganic filler is about 170 microns, but may lie in the range from 170 to 200 microns. Particles of this size are different from particles commonly used in the tobacco substitutes of the filler, the particle size of which is only 2-3 microns. Particles of various inorganic fillers may have different sizes from 1 up to 1 mm (1000 μm). Particles of the required size is obtained by grinding, milling or deposition of inorganic filler.

As the inorganic filler can be used perlite, aluminum oxide (alumina), diatomaceous earth, calcium carbonate (chalk), vermiculite, magnesium oxide, magnesium sulfate, zinc oxide, calcium sulfate (gypsum), iron oxide, pumice, titanium dioxide, calcium aluminate or other insoluble aluminates or other inorganic fillers. The density of the fillers should be in the range from 0.1 to 5.7 g/see it is Preferable that the filler had a density of less than 3 g/cm, more preferably less than 2.5 g/cm, most preferably less than 2.0 g/cm, especially predpochtitel is but less than 1.5 g/see It is most expedient to use a filler with a density less than 1 g/see Low density inorganic filler reduces the density of the material of the product and thus improves slidenote ash.

When used in the Smoking product of a mixture of fillers to create the desired average particle size of particles of one or more fillers can have a smaller particle size, and particles of other fillers - large size. The necessary static intensity burning finished Smoking products can be achieved using smoked Nachinaem material acceptable mixture of tobacco and proposed in the invention of the Smoking material.

The inorganic filler should not be in agglomerated form. Before using the filler sometimes put a small preview processing different from the processing necessary to obtain particles of the desired size.

As you can use agar, agarose, carrageenan, fucoidan and force laran. As the organic binder can be used and starches. Suitable for use in stipulated izobreteniem purposes gums are described in the corresponding references, for example in the Handbook of Industrial Gums, E.Whistler (published by Academic Press).

The most preferable of the above binders are alginic binder. The use of alginates, preferably according to the invention for the reason that the products of combustion have a neutral taste and therefore do not affect the taste of the smoke produced when Smoking Smoking products.

Preferably, the contents of the aerosol forming substances in the proposed invention the Smoking material ranged from 5 to 20%, more preferably up to 15%, mainly more than 7%, most preferably more than 10%. Preferably, the contents of the aerosol forming substances was less than 13 wt.%, more preferably from 11 to 13 wt.%, most preferably about at 11.25 wt.% or even to 12.5 wt.%, in terms of the weight of the finished sheet Smoking material. With a reasonable amount of aerosol forming substances selected in accordance with the quantity of tobacco to be included in the composition of the mixture, forming smoked naconechny material proposed in the invention of Smoking products. For example, in a mixture containing b is lsoe number of leaf Smoking material with a low content of tobacco, you may want to reduce the contents of the aerosol forming substances in this sheet Smoking material. Conversely, in a mixture containing a small amount of leaf Smoking material with a high content of tobacco, you may want to increase the contents of aerosol forming substances in this sheet Smoking material.

As the aerosol forming substances can be used polyhydric alcohols such as glycerin, propylene glycol and triethylene glycol, esters, such as triethylcitrate or triacetin, high-boiling hydrocarbons or low molecular weight alcohols, such as glycols, sorbitol or lactic acid. In the proposed invention in Smoking material can be used and a mixture of several aerosol forming substances. In addition to its primary purpose aerosol forming substances are used as a plasticizer in the manufacture of sheet Smoking material. As an additional plasticizer water can be used.

Smoking material it is advisable to saturate the air. To do this, use is made of the pulp sheet Smoking material with cellular structure.

Forming the aerosol substance or a certain part can be used in encapsulated form, preferably in the form of microcapsular what about the form, or to stabilize them in some other way. In this case, the amount of aerosol forming substances must be greater than specified above.

The proposed invention in Smoking material it is advisable to add a dye to impart a Smoking material a darker coloring and/or flavoring to make Smoking material specific aroma. Such flavoring or coloring materials include, for example, cocoa, licorice, burnt sugar, chocolate or toffee. For this purpose you can also use finely ground, granulated or homogenized tobacco. In addition, in the proposed invention the Smoking material you can use well-established in the food industrial food dyes, for example EA (sugar Kohler I simple), E (black shiny BN), E153 (vegetable charcoal) or E (brown HT). It is suitable for use flavorings include, for example, menthol and vanilla. You can use other dosiruyushaya materials. It should be noted that the Smoking material in the presence of vermiculite or other inorganic fillers can already buy a dark color.

The amount of dye in the proposed invention the Smoking material must be from 0 to 10%, preferably from 5 to 7%, in terms of mass g is a Hilbert Smoking material. Preferably, the amount of dye was less than 7%, more preferably less than 6%, mainly less than 5%, calculated on the weight of the finished Smoking material. In a particularly preferred embodiment, the amount of dye must not exceed 4, 3 or 2%. The cocoa content in the proposed invention the Smoking material should preferably be from 0 to 5%, and licorice - from 0 to 4%, calculated on the weight of the finished Smoking material. When used as a dye cocoa or licorice minimum content of cocoa to give the Smoking material of the desired color should be about 3%, and licorice - about 2%, calculated on the weight of the finished Smoking material. The content in the Smoking material burnt sugar should range from 0 to 5%, preferably up to 2%, more preferably up to 1.5%, calculated on the weight of the finished Smoking material. Other usable dyes include molasses, malt extract, coffee extract, resinoids tea extract, carob extract, prune extract of tobacco. In the manufacture of the proposed invention in Smoking material can be used and mixtures of dyes.

To change the taste and flavor of Smoking material it is possible to add various flavorings.

When used and as an alternative dye food coloring its content should be about 0.5% or less, calculated on the weight of the finished Smoking material. To change the color of the finished sheet Smoking material you can simply sprinkle the corresponding dye.

To increase the strength of the Smoking material, reducing its density or increasing the density of the packing it is possible to add fibrous material, for example cellulose fibers, in particular wood pulp, tow (flax fiber, hemp fiber or bast fibres. Adding to the Smoking material, fibrous material, its quantity should be from 0.5 to 10%, preferably less than 5%, most preferably less than 3%, calculated on the weight of the finished sheet Smoking material. However, the most preferred is a Smoking material which does not contain any fibrous material is neither cellulose nor any other.

As proposed in the invention of the Smoking material, it is preferable to use a sheet Smoking material that does not contain tobacco.

It should be noted that a mixture with a high content of leaf Smoking material in excess of, for example, 75%, calculated on the weight of the mixture, has poor combustibility. To eliminate this disadvantage can, for example, by adding in the Smoking material of granulated coal in a small amount constituting from 5%to 10%. In before Occitania version granulated charcoal should not be in agglomerated form, ie should not be pre-mixed with any other material with which it is able to aglomerirovanie.

Smoked naconechny material is preferably obtained by mixing proposed in the invention of crack material with the tobacco material. For preparation of such mixtures, it is advisable to use a thin lamina of high quality tobacco. In a preferred embodiment, the main part of the tobacco material should be at a fine-cut tobacco. The tobacco material may contain from 20 to 100% extended (expanded) tobacco obtained by the method of high expansion, such as the loosening of carbon dioxide. Specific volume of such tobacco material is usually from 6 to 9 cm/g (see, for example, GB 1484536 and US 4340073).

In addition to fine lamina tobacco blend may contain up to 30% of other components, which include cut flattened veins (FPW)treated water veins (OUR) or steamed ribs (LE), and reconstituted tobacco. The share of such other components in the preferred embodiment, should have no more than 20%, more preferably less than 10%, most preferably less than 5%, calculated on the weight of the finished tobacco material.

Used in the present invention in Smoking tobacco product can handle brazowski aerosol substances. However, this treatment aerosol forming substances is not mandatory for all mixtures of tobacco sheet material and the Smoking material. The number of added tobacco aerosol forming substances must be in the range of 2 to 6 wt.% in terms of the mass of tobacco. The total number of aerosol forming substances in a mixture of tobacco and Smoking material should be from 4 to 12 wt.% in terms of the weight of the Smoking material, preferably from 5 to 10 wt.%.

The tobacco material can optionally contain sowerbyi material, and using the American tobacco mixture (US Blend) containing tobacco Burley parts of this mixture, you can add normal sowerbyi material, and to the rest of you can add or not add a light sowerbyi material.

As the tobacco material can be used tobacco, processed by the method described in patents US 5803081, US 6135121, US 6338348 or US 6202649 (which are included in the description as the link), with reduced levels of tobacco specific nitrosamines (STN). Proposed in the invention of tobacco products with this tobacco may even have a lower LOCAL content than commercially available conventional tobacco products like tobacco. In the proposed invention in Smoking articles, the Smoking material which sod is Ritsa only a small part of such tobacco, the LOCAL content is even lower. For this kind of tobacco specific nitrosamines include N-nitrosonornicotine (N-HH), N-nitrosoanatabine (N-AT), N-nitrosoanabasine (N-AB) and 4-(N-nitrosomethylamino)-1 -(3-pyridyl)-1-butanone (N-HM).

Another tobacco material, which can be used in the proposed invention the Smoking product is processed by enzymes tobacco (fermented tobacco), as described in the application WO 00/02464 or in patents US 5311886 and US 5560097, which are also included in the present description as a reference. In the last two patents for the removal of tobacco protein is proposed to use an enzyme (protease) together with surface-active substance or without him. In the above-mentioned international application for removal of polyphenols from an aqueous extract of tobacco instead of polyvinylpolypyrrolidone (PVPP) proposed to use the laccase.

The ratio between the amount proposed in the invention of Smoking material and a quantity of tobacco in the proposed invention the Smoking product is preferably from 25:75 to 75:25, more preferably from 50:50 to 60:40, most preferably about 60:40. This ratio may be 50:50 or 50:45 depending on the required degree of dilution of the components of tobacco smoke. If you do not want too strong dilution of components that is ajnogo smoke against Smoking material tobacco can range from 10:90 to 25:75. The results of the analysis of smoke with a 5%increase or decrease in the number of Smoking material or tobacco below. From this analysis it follows that the transfer efficiency of aerosol smoke even when the above ratio the proposed invention Smoking products is higher than in the simple addition of aerosol forming substances in fine-cut tobacco.

The density of the finished product, consisting of mixed tobacco sheet material and the Smoking material may be from 300 to 360 mg/cm3or from 320 to 350 mg/cm3. The relationship between tobacco sheet material and a Smoking material must be such that the density of the finished product did not exceed 300 mg/cm3. In a preferred embodiment of the invention the density of the finished product, consisting of mixed tobacco sheet material and the Smoking material shall conform to the density of normal tobacco, i.e. from approximately 220 to 240 mg/cm3.

The present invention allows to obtain a wide range of values of the rates of transfer in the smoke of the various components of the Smoking material. The use of the proposed invention in Smoking products ventilation allows to reduce the share in the main stream smoke contains nicotine dry particles (NSSC) to level m is it 9 mg. The content in the smoke NSSC can be reduced to 2-6 mg and, in particular, to 3, 4 or 5 mg When determining the rate of transfer into account number of the source contained in the Smoking material forming the aerosol substance. Instead ventilation, or in addition thereto, to reduce the content in the smoke NSSC you can change the composition of the mixture of smoked acinacea material, bringing in it the number proposed in the invention of the Smoking material. The degree of ventilation of the Smoking articles may exceed 30%, preferably less than 40%, mainly to exceed 50%, and even more. For better ventilation of the Smoking product, you have to punch paper addressed to the mouth of the smoker end Smoking products.

In the wrapper for Smoking articles may include a fuel additive, such as sodium citrate and/or potassium. Experts know and other combustible additives, for example, sodium or potassium salts such as acetate or tartrate, phosphate and intrigejosa. The quantity of combustible additives should be from 0.5 to 2.5 wt.% in terms of the weight of the wrapper. The specific weight of the wrapper must lie in the range from 20 to 40 g/m2.

Proposed in the invention, the Smoking article may have slightly reduced the circumference of the outer surface, which is preferably from 22 to 25 mm. In principle the e the circumference of the outer surface of the proposed invention in Smoking products may be less than 22 mm

Proposed in the invention of a Smoking product in addition to the core with the proposed invention is a Smoking material has a filter element (filter)which can selectively reduce the content in the main stream smoke of some of its components. The filter allows, in particular, to reduce the content in the main stream smoke of various volatile and semi-volatile components.

Compared to conventional Smoking products with the same content in the smoke particles present invention allows to significantly reduce the content in the smoke of various carbonyl compounds.

For the manufacture of filter it is advisable to use a powder material, such as granulated charcoal, which can be provided in activated form. As activated charcoal can be used the coal contained in the following filter types Trionic. As the activated carbon, it is preferable to use activated carbon coconut. As a powder containing the filter material can be used in dual combination filter, for example, with a gasket of cellulose acetate in facing to the mouth of the smoker part and a rod with patches adjacent to the tobacco part. One of the parts of the combined filter can be made of paper. In another embodiment proposed in the invention of crack product it is possible to use a filter known as the Active Patch (firm Filtrona International) and are described in UK patent 2249936. In another embodiment, in the proposed invention the Smoking product it is possible to use a porous filter, consisting of two end sections and the Central part filled with granular material.

In another embodiment, the filtering element, you can use the filter type "Trionic" with selective filtering ability, described in provisional patent applications U.S. 60/309388 and 60/309435 from August 1, 2001 (see Fig.1-3). Shown in figure 1 triple combination filter (130) is located in the tobacco rod (20) the first section (136)containing a selective adsorbent, Central second section (134)containing the adsorbent General purpose, and is directed to the mouth of the smoker third section (132), containing the usual fibrous material such as cellulose acetate. These three sections are enclosed in a single wrapper (135). Such a filter provides a synergistic reduction in the smoke of certain components. Section (134) with adsorbent General and section (136) with a selective adsorbent can be swapped, as shown in figure 2.

The selective adsorbent is preferably selected from the group of resins with surface functional groups, each of which (resin) is essentially inert novtel is with a sufficiently large for the adsorption of specific components of smoke surface area. As a selective adsorbent, it is preferable to use ion-exchange resin, such as resin duolith A7 (manufactured by Rohm and Haas, located at: 5000 Richmond St., Philadelphia, PA 19137, USA), or another material with similar functional groups and with similar binding properties. Resin duolith A7 has a phenol-formaldehyde matrix and functionalized on the surface of primary and secondary amino groups, which increases the specificity of the resin with respect to contained in tobacco smoke aldehydes and hydrocyanide.

Selective adsorbent should have a specific surface area, enough for easy penetration of smoke to its functional centres with minimum diffusion resistance. For example, a resin with a specific surface area of more than 35 m /g can effectively adsorb smoke components, provided that the density of the packing of the resin should not be so large to create a high resistance passing through the filter the smoke. In addition, the substance with the greater specific surface area less lose their properties when coating their surfaces with a plasticizer, which is characteristic of adsorbents, evenly distributed in the entire volume of the filter pad.

The adsorbent General purpose it is preferable to select from a group of adsorbents with relatively the largest surface area, able without a high degree of specificity to adsorb components of smoke. As examples of such adsorbents can be called adsorbents from the group comprising activated charcoal, activated carbon, coconut activated carbon or charcoal-based coal (coal with incorporation of crop residues), zeolite, silica gel, thick, aluminum oxide (activated or inactivated), carbon resin, and combinations thereof. An example of a coal-based coal can be polyatract, the density of which is 50% more density of charcoal from coconut (manufactured by a company Calgen Carbon that is located at: Pittsburg, PA, WA). An example of a carbon resin may be a resin obtained by pyrolysis of sulfated stradivariuses, for example resin ambersons 572 or ambersons 563 (produced by the firm Rohm and Haas). To improve the efficiency of the adsorbent General purpose containing the filter section you can add metal oxides or other metal complexes or to impregnate containing the filter section of these substances.

The adsorbent General and selective adsorbent can be distributed throughout the volume of the fibrous material of the filter pad, i.e. to perform the type of filter patches (see figure 1 and 2) or to place them in the amount of fibrous material of the filter pad in the form of a densely Packed layer or in the form of a thin layer of adsorbent, i.e. in the empty space between two or three adjacent filter tampons (142) of the fibrous material or in a cavity or pocket formed in the pad (see figure 3). Such densely Packed layers or thin layers (144, 146) of the adsorbent can also be performed in penetrating sections interspersed with to achieve different filter effects.

The amount of each adsorbent in the filter is from 10 to 80 mg, preferably from 20 to 60 mg, and most preferably at least 40 mg of each adsorbent in each section of the filter and is dependent on the effectiveness of filtering each component of the smoke. The total number of both adsorbents in the filter should be from 60 to 110 mg.

Converted to the mouth of the smoker section of the filter can be manufactured from various materials, for example of cellulose acetate (ultrafine cellulose acetate tow, cellulose, paper, wool, polypropylene web, polypropylene tow, polyester products, polyester tow, or combinations thereof, and adjacent to the rod of smokable acinacea material section is interspersed with particles of an absorbent or adsorbent. The filter element can have a wrapper with glued particles.

In addition, depending on the characteristics of the final crack developed products required parameter the mechanics area and characteristics of the smoke filtration can be ensured by selection of appropriate values of the pressure drop in the individual sections of the filter and/or efficiency they provide mechanical filtration.

Simultaneous use in Smoking products offered in the invention smoked acinacea material and the above-described filter element can significantly reduce the content in the main stream smoke of some of its components, in particular carbonyl components of smoke, such as formaldehyde, acetaldehyde, acetone, acrolein, propionic aldehyde, CROTONALDEHYDE, methyl ethyl ketone and butyric aldehyde, phenol, such as phenol, o-cresol, m-cresol, n-cresol, catechin, resorcinol and hydroquinone, aromatic amines such as 1-aminonaphthalene, 2-aminonaphthalene, 3-aminonaphthalene and 4-aminonaphthalene. At the same time is significantly reduced and the content in the main stream smoke hydrocyanide.

The content of many of the above compounds as a percentage in terms of number does not contain nicotine dry particles (NSSC) is reduced by 15% or more, preferably 20% or more, most preferably 25% or more and the content of some compounds may be reduced to not less than 30, 35 and even 40%. For some mixtures with a certain amount of tobacco and a certain degree offered in the invention of the Smoking material, the content of these compounds in the main stream smoke has fallen by more than 60%.

The filter of a different design, which can also be used in th is proposed in the invention of the Smoking product, as described in the application PCT/GB 02/005603. Described in this application, the filter has a filter pad (16) of the homogeneous filtering material, a wrapper (18), which wrapped filter pad (16), made on the outer surface of the filter pad (16) with equal angular increments in its circumferential direction of the longitudinal grooves and double paper vents connecting the filter element (14) with the tobacco rod, while in some of the grooves (20), which are parallel to the axis of the filter element and open from the tobacco rod (12)and only to a certain length filter element (14) and therefore do not reach converted to the mouth of the smoker's end of the filter element (14), through the vents, such as paper enters the ventilating air, while the other grooves that reach converted to the mouth of the smoker's end of the filter element, not ventilated.

In the filter of this design the ventilating air enters the groove, the open side of the tobacco rod, and then reverses direction and moves to the inverted mouth of the smoker to the end of the filter. When such movement is passing through the filter ventilating air is significantly reduced in the smoke, the ratio between CO and resin. This ventilation of the filter in combination with selectively dt is berowski pair of powder additives can significantly reduce the content in the smoke vapor the various components of the Smoking material.

In addition it should be noted that the use proposed in the invention of crack material significantly reduces the propensity for fire Smoking products with such a Smoking material. When testing the propensity to fire, for the following standard methodology NIST found that within a certain time all samples proposed in the invention of Smoking products left on the filter paper Whatman or on canvas, faded, and the control cigarette continued to burn.

In the present invention it is also proposed a method of regulating the rate of combustion in the static mode Smoking products, which is wrapped by the wrapping of the rod of smokable acinacea material, which includes some amount of Smoking material consisting of alginic binder, forming the aerosol substance and non-combustible inorganic filler, in which some part of the accounts for particles, the average size of from 500 to 20 μm, namely, that the rate of combustion in the static mode adjust by selecting a specific particle size of the inorganic filler and/or select the number of Smoking material in combination with the amount of tobacco material in a mixture of smoked nacino the aqueous material.

According to the invention it was also found that, selecting accordingly the particle size of the inorganic filler, it is possible to modify the burning rate proposed in the invention of the Smoking material in the static mode, without changing its composition. This feature of the proposed invention in Smoking material significantly enhances the creation of new Smoking materials and new cigarettes. In addition, selection of the appropriate particle size of the inorganic filler can be largely influenced by the taste and aroma characteristics and/or physical characteristics of Smoking articles containing proposed in the invention of the Smoking material.

In a preferred embodiment of the invention, the rate of combustion in the static mode Smoking products offered in the invention sheet Smoking material is 3 to 8 mm/min. In a more preferred embodiment, this speed is from 4 to 7.5 mm/min. In the most preferred embodiment of the invention, the burning rate proposed in the invention of Smoking products is from 4 to 6 mm/min

Proposed in the invention, the Smoking article can be wrapped with two layers of cigarette paper, one of which, usually the outer layer, making it more dense.

In the proposed in ISO is reenie Smoking product instead of a paper wrapper or in addition to it, you can use the wrapper described in applications WO 96/07336 and WO 01/41590. Such wrappers reduce the side stream smoke, but does not change the characteristics of the combustion and ashing, which remain the same as traditional Smoking products. The composition of such wrappers may include ceramic powder filler with particles of a certain shape, the amount of which is from 50 to 95 wt.% in recalculation on weight of dry solids in the pulp, which produce the wrapper, binder, and optional fuel additive, and optionally a means of improving slidenote ash.

in figure 1, 2 and 3 - filter elements (filters) proposed in the invention of Smoking products and

figs.4 and 5 - graphical representation of the results of the tests are shown in table 4.

Example 1

Proposed in the invention of the Smoking material produced from a dry composition weight of 3 kg, containing 74% of chalk (inorganic filler), 12% glycerol (aerosol forming substance), 8% of sodium alginate (binder), 4% cocoa and 2% licorice (dyes/fragrances). To the dry mixture of chalk, gli is Wendy Erin, cocoa and liquorice gradually added to 8 l of water. Together with water to the mixture was added to the alginate. The mixture was thoroughly stirred by a Silverson mixer to obtain a slurry of the desired viscosity was reached (30000 SP).

Then from the pulp molded a wet sheet with a thickness of 1 mm, which was dried in a drum casting machine heating. Dry leaf material was crushed in a shredder at 37 cpi, mixed with shredded tobacco and the resulting mixture was processed into cigarettes. As the wrappers of the cigarettes in length of 84 mm filter length 27 mm used paper with a permeability of 50 CU. Table 1 provides data on the mixture composition and physical properties used for its preparation of chalk. As a reference cigarette used a cigarette with 100%content of the tobacco mixture that is composed entirely of a mixture of leaf tobacco Burley and Oriental type, both traboulay drying, with 40% of the total amount of the mixture were expanded tobacco, obtained by dispersing carbon dioxide. Each group of test cigarettes contain a blend of 40% tobacco and 60% proposed in the invention sheet Smoking material. Test cigarettes were carried out in the mechanical mode area in terms of the relevant ISO standard, with one puff volume of 35 cm and a length of two seconds during each minute.

From the data in table 1 it follows that with decreasing particle size the rate of combustion Smoking articles in static mode increases. By the selection of optimum particle size and preparation of a mixture of particles of different size can be significant is about to improve the quality of Smoking products.

Example 2

Made a few other designs proposed in the invention of the Smoking material. For their manufacture used chalk with particles of different sizes. After casting and cutting of the sheet received Smoking material was mixed with a mixture of shredded tobacco. As a control used tobacco blend which meets the tobacco mixture, and that the cigarettes are marked as S568. From the obtained materials were made cigarettes with the length of the outer circumference of 24.7 mm and a total length of 83,5 mm when the length of the filter of cellulose acetate, equal to 21 mm as wrappers of the cigarettes used paper with a permeability of 50 CU. All cigarettes were kondicionirovanie at a temperature of 22±1°C and 60%relative humidity (±2%) for at least 48 hours. The burning rate of these cigarettes in the static mode was measured on the test machine company Filtrona (model FBR100). The results are given in the table below.

From the table 2 data shows that the tobacco mixture burns faster than other Smoking materials. With the increasing size of the particles of chalk, the rate of combustion in the static mode is reduced. In addition, with the decrease in the number of Smoking material in the mixture, the rate of combustion increases. These data are confirmed by the test results obtained in example 1.

Example 3

Drum casting mixture containing 78.5% of chalk, 12.5% glycerol, 7.5% of a binder and 1.5% burnt sugar (EA), received sheet Smoking material. The chalk particles had an average size is about 170 μm. Tests of this sheet Smoking material showed that it has satisfactory characteristics corruption and physical characteristics, such as ashing.

Example 4

Drum casting mixture containing 75,25% of chalk, 11,25% glycerol, 7.5% of the binder, 4% cocoa and 2% licorice, received sheet Smoking material. The chalk particles had an average size of about 170 μm. Testing of this material showed that it also has satisfactory characteristics corruption and physical characteristics, such as ashing. The burning rate in the static mode was equal to 4.72 in mm/min

Example 5

In this example, produced three groups of cigarettes. Cigarette with a code designation S295 had a length of 83,5 mm, the length of the circumference of the outside diameter of 24.7 mm and a filter length of 20 mm and a density of 199 mg/cm3. Cigarettes-samples, code designations S384 and S382 had a length of 84 mm and a circumference on the outer diameter of 24.7 mm and a filter length of 20 mm and a density of 229 mg/cm3and 340 mg/cm3respectively. One group of cigarettes was made entirely of tobacco (the same as in example 1), the second group of cigarettes used sheet Smoking material, which contained only chalk V100, and in the third group of cigarettes used sheet Smoking material, which contained only precipitated chalk. The composition of listowel the Smoking material complies with the specified in example 4.

From the table 3 data follows that proposed in the invention of tobacco products despite the fact that they smoked naconechny material is 60 percent of the proposed invention sheet Smoking material, have the same or almost the same combustion characteristics as cigarettes containing only tobacco.

Example 6

To study the effectiveness of the lane is a nose spray (EPA) using the proposed invention in sheet Smoking material in a mixture with tobacco in comparison with fine-cut tobacco, treated with different quantities of the humidifier, manufactured several samples of cigarettes.

Made a batch of cigarettes with 100%American blend tobacco (code cigarettes BW007). The density of tobacco in the samples of cigarettes BW007-2, BW007-3 and BW007-4 was 264, 263 and 264 mg/cm, respectively. The amount of glycerin in the mixture ranged from about 4% to about 12%. Were also produced a batch of cigarettes with a tobacco mixture that is 40% consisted of the same American tobacco mixture and 60% of the proposed invention the Smoking material (samples S480, S408, S481, S479, S559, S483 and S407). The total amount of glycerol in the mixture of tobacco and leaf Smoking material ranged from about 3.5% to about 8%. Tobacco, included in these concrete mixtures, glycerol was added. The density of a tobacco mixture of these samples of cigarettes were 315, 207, 321, 324, 320, 312 and 227 mg/cm, respectively. Made another batch of cigarettes with tobacco traboulay drying at the same ratio of between tobacco and proposed in the invention of the Smoking material, equal to 40:60 (samples S619, S623, S621, S549 and S620). The density of a tobacco mixture of these samples was 333, 299, 320, 328 and 255 mg/cm, respectively. Obtained in this example the results are given below in table 4.

From the table it follows that the transfer efficiency of spray, in this case, the transfer efficiency of glycerol (PGE), in cigarettes, 100% filled with tobacco blends decreases with increase in the content of glycerol. Conversely, PGE cigarettes offered in the invention smoked Nacional material was higher than PGE control cigarettes with 100%stuffing tobacco mixture, excluded the eat one cigarette (S620), stuffed with a mixture with a low content of glycerol. For example, comparing two samples of cigarettes (S559 and BW-007-3) with almost the same content of glycerin, it can be noted that PGE cigarettes S559 43% higher than PGE control cigarettes. Comparison of PGE equal 4,35 in the cigarette S620 with a lower content of glycerine (of 3.77%), PGE (4,28 or 4,77) cigarettes, 100% made from tobacco mixture, the greater the effectiveness of the present invention in use in the Smoking material of glycerin.

Table 4 presents the data graphically presented in figure 4 and 5.
