The product applies to Smoking, particularly cigarettes. Crack product contains a wrapping material forming the wrapper tobacco Smoking products. The wrapper consists of a ceramic filler in the form of particles having a particular form, and a binder. The amount of ceramic filler particles is from 50 to 95 wt.% in terms of the mass of dry matter in suspension, which made the wrapper, and the wrapper has a porous self-sustaining structure. This Smoking product is simplified technology of its production. 33 C.p. f-crystals, 2 ill., 5 table.

The invention relates to Smoking articles, and primarily, but not exclusively, to cigarettes.

In recent years there has been extensive work has been performed, aimed at creating Smoking products with a reduced content of various components in side-stream smoke (i.e., in the smoke generated in the process area, but not inhaled directly by the smoker). Many of these works were associated with the use of Smoking products for various not containing tobacco Smoking materials, such as Smoking materials non-combustible inorganic dopolniteljnie product with a high content of non-combustible inorganic material and essentially non-combustible wrapping material, which the entire length of the wrapped rod of Smoking material, as well as the fuel source and the means forming the aerosol. This proposal, however, relates to Smoking articles, in which the Smoking material is not tobacco or essentially does not contain tobacco and has a high content of inorganic substances. Unlike the wrappers of cigarettes with tobacco Smoking material wrap used as proposed in this proposal cigarettes, does not support the normal mode of the area corruption inside the cigarette. Normal (standard) mode area suggests that the smoker with an interval per minute for 2 seconds makes one puff volume of 35 ml

In the application WO 98/16125 proposed reusable ceramic tubular materials made mechanical by narrow slits, covered with a porous material. Such ceramic tubular materials during Smoking not expire until the end and are usually located between the tubular material and the tobacco filler (inset) the annular passage, necessary for combustion air. In one embodiment in this application as a wrapper tobacco inserts are encouraged to use cloth ceramic fiber. Such wove tobacco paste. Proposed in this application the fabric of ceramic fiber does not burn until the end. In another embodiment, in this proposal it is proposed to use as wrapper tobacco rod rolled in a tube sheet of moderately calcined (sintered) of fibrous material in which at least the binder burnout substances are formed pores. Used in this product ceramic tubular material does not burn or after pre-firing does not burn until the end and therefore can be used repeatedly.

In the application WO 99/53778 it was proposed to use for the manufacture of cigarettes specially treated to reduce the content in side-stream smoke of the various components obtained from the active non-combustible components of sheet material, which as a result of processing becomes porous structure, reduce the content of the various components in side-stream smoke. The treated sheet material is a hydrophobic sorbent material with high porosity and micro-pores of large size, i.e., a material having a large surface area and can absorb particles of another material. In the composition of the sheet material preferably having visualaid componenti. Inside sheet material Smoking material is shredded or cut tobacco. When Smoking the proposed product is sorbirovaniya nonaqueous vapor phase Smoking material and a more complete combustion in oxygen-enriched atmosphere. This also happens selective chemical filtration side stream smoke. Proposed in this application is specially treated to reduce the content of the various components in side-stream smoke material does not burn to the end at the time of Smoking, and therefore made out the product during Smoking differs from regular cigarettes.

In both the above-mentioned publications do not contain any information about the wrapper for the Smoking product, which in the presence of such a wrapper formed during Smoking ashes is no different in its properties and appearance from the ash produced when Smoking regular cigarettes.

In the patent US 4915117 proposed cigarette with a thin sheet that holds the tobacco inside cigarettes. In one of the covered in this patent variations of this thin sheet is produced by applying to the paper coating of the inorganic binder (or by impregnation of the boom is. is written in this patent wrap requires for its production of paper material forming a carrier substrate, on which the ceramic layer.

The present invention was based on the task of developing a Smoking article with the usual Smoking material and not the traditional wrapper containing a certain amount of non-combustible material and forming process area visible line burning, which gradually changes its position along the length of the Smoking product.

Another objective of the present invention consisted in the development of Smoking products, which did not differ from normal cigarettes on properties formed during Smoking ash, which is removed or shaken from the proposed invention Smoking products in the usual way, namely, that the smoker or simply dampens the product, or flip it and shakes off the formed ash.

Another object of the invention consisted in the development of the wrap, which would not require for the formation of porous structure of thermal ageing. Remove from the proposed invention wrapper moisture in the drying process, not heating the wrap over 280C. When naked is called the "wrap with unfired ceramics". Under the "wrap with unfired ceramics" in this case refers to the wrapper, which is in the process of its production is not heated to over 100C.

The invention consisted in the development of wrappers, which would not require machining to make it necessary for combustion porosity.

The present invention offers a Smoking article containing a wrapping material forming the wrapper tobacco Smoking material. This Smoking product is characterized by the fact that the wrapper consists of a ceramic filler in the form of particles having a particular form, and a binder, the amount of ceramic filler particles is from 50 to 95 wt.% in terms of the mass of dry matter in suspension, which made the wrapper, and the wrapper has a porous self-sustaining structure.

Due to the specific form of the particles of ceramic filler mixed in a wrapping material in a certain proportion with a binder, the wrapper has a porous self-sustaining structure and loss of integrity during combustion during Smoking. As a wrapper, it is advisable to use the wrapper from the unfired pottery.

In a particularly preferred embodiment, the amount of binder in the slurry should be from 3 to 10 wt.%. It should be noted that the number keramicheskoj the>bertka proposed in the invention of Smoking products may also contain an additive that improves the combustion of the wrapper. The amount contained in the wrapper proposed in the invention of Smoking products supplements, contributing to its combustion, should be greater than in paper wrappers. The amount of such additives in suspension, from which the material for the manufacture of wrappers proposed in the invention of Smoking products should be calculated on the weight of dry substance in the suspension is preferably from 1 to 15 wt.%, more preferably should not exceed 10 wt.%, most preferably should not exceed 5 wt.%. In a particularly preferred embodiment, the number of improving combustion wrapper additives in the slurry should be from 2 to 5 wt.%. This additive improves the combustion wrapper, preferably represents an accelerator or activator of combustion. As an additive that improves the combustion wrapper, and contained in the suspension, from which the material for the manufacture of wrappers proposed in the invention of the Smoking articles can be termed used, including different combinations of salts of metals of group I or II of the Periodic system of elements, such as Aqua should give the wrap optimal in relation to the combustion properties and also to give a formed in the process of Smoking the ashes of the most appropriate color. Such additives may, in particular, to serve the remainder contributing to the seizure of the agent or agents are described in more detail below.

In accordance with this wrap proposed in the invention of Smoking products may contain additives that improve the properties of the ash. Such an additive that improves the properties of the ash, is intended for the formation of bridging ties between the particles of ceramic filler or to increase its density. In the invention the task of creating wrappers, clean-burning during the area with the formation of ash similar to the ash produced when Smoking regular tobacco products. In the manufacture of wrappers proposed in the invention of Smoking products individual components of wrapping material, in particular ceramic filler and additive to improve the properties of the ash, used in the form of particles of a certain size and/or shape, with the appropriate combination of which wrap up its combustion acquires the necessary strength, which she during combustion loses, resulting from burning during Smoking products formed with neobhodimo morphology and mixed with a ceramic filler to give the wrapping material necessary permeability and goremote and education ashes with a certain strength and color. The number of improving properties of ash additives in a wrapping material, the presence of which is optional, should preferably be from 0 to 5%. Materials that unlike ceramic filler in the form of rounded particles form must have a corresponding plate-like morphology, are used in different combinations substances from the group comprising mica, chalk, perlite, alumina, for example vermiculite, and kaolinites and only. These materials after grinding to particles of appropriate sizes and shapes can also be used as a ceramic filler.

In another embodiment, as an additive for improving the properties of the ash, it is possible to use a material consisting of very fine particle size, which fills the voids between larger particles of ceramic filler.

As additives that improve the properties of ash, you can also use the material, which increases the pH of the suspension, from which the material for the manufacture of wrappers. These materials can increase the pH of the suspension 8 to about 10, are salts of metals of group I or II of the Periodic system of elements, representing carbonates, and GI is nicemedia, which preferably does not exceed 200 units of Coresta and is preferably from 2 to 100 units of Coresta. The permeability of the wrapper of the proposed invention in Smoking products in the most preferred embodiment is 5 to 50 units of Coresta and may be less than 10 units Coresta.

Wrap the proposed invention in Smoking products must have a density from 0.5 to 3 g/cm3preferably from 0.8 to 1.2 g/cm3more preferably about 1 g/cm3and the necessary tensile strength, at which it remains intact when performing various operations manual. The thickness of the material from which made the wrapper proposed in the invention of Smoking articles should be between 0.2 to 0.6 mm

The wrapper proposed in the invention of the Smoking articles are preferably made in the form of a tube according to the method described in the application WO 96/07336.

For the manufacture of such tubes use a thick slurry, which consists of members of the wrapping material components, and which is applied in the form of a coating on a rotating mandrel, removing excess moisture by physical or chemical means. Manufacture of the suspension tube by extrusion, skipping that is, in addition, it can also get a sheet of wrapping material, using for this purpose the drum or belt casting machine or extruder with a corresponding cylinder. The prepared suspension can also be sprayed under pressure to apply a coating on collected with each other of the fuel and aerosol components of Smoking articles.

The pressure at which the extrusion of suspension shall not adversely affect the permeability of the wrapper, and therefore, for example, in the cylinder, a piston extruder, it should not exceed 3-4 bar (300-400 kPa), and in the head of a screw extruder type APV Baker Perkins should not exceed 9 bar (900 kPa). In the extrusion process for the formation of the cellular structure at the outlet of the extruder crosshead suspension sometimes churn, and in these cases the pressure in the cylinder of the extruder is increased, limiting its value with which the resulting material for the manufacture of wrappers will have the necessary permeability.

After or before extrusion of suspension or deposition of the coating on the respective mandrel tube (extrudate) or frame output from the head is heated, removing from the suspension of excess moisture. The composition of the suspension, from which the m is destructive, for example, 40-50With, such as potassium silicate, magnesium oxide or hydroxypropylcellulose. When heated, covered by a layer of the suspension mandrel or manufactured in the extruder tube (extrudate) this binder becomes active and stabilizes the wrapper. For heating coated with a layer of a suspension frame or manufactured in the extruder tube, it is preferable to use infrared or microwave radiation, as direct heating using, for example, generated by the blower hot air flow can lead to a distortion of the shape of wrapping material, especially at temperatures exceeding 100C.

For the manufacture of suspension of wrapping material can be used single or twin screw extruder, a piston extruder or a pump for pumping the suspension.

Typically, the wrap has a thickness of from 0.1 to 1.0 mm, although in some cases you may need to use a shim thickness of 2-3 mm Thickness wrapper depends on its mass and permeability. However, depending on the composition of the suspension, from which the wrapping material, it is possible to make and dense thin wrapper, and a thick wrap with a low density.

Stablisheth dewatered suspension, which produce the wrapper, and eventually dried up. As such substances can, for example, to use a light-weight magnesium oxide, adding it to form a slurry mixture in an amount of up to 45 wt.% in terms of the weight of the dry components of the suspension with respect to temperature and residence time of the slurry in the extruder. The addition of a slurry of magnesium oxide also allows you to visibly reduce and content of the various components in side-stream smoke. To stabilize the wrap can also extrusion of wrapping material in a bath filled with ethanol or other possessing a pronounced hydrophilic properties of the substance. To reduce the amount of moisture produced in the extruder wrapper can also deposition of insoluble alginate contained therein soluble alginate. This can, for example, to ekstradiroval tube containing sodium alginate wrapping material in a bath with normal electrolyte or electrolytes, filled, for example, 1-molar solution of calcium chloride. What is happening in the bath electrolyte replacement of sodium ions by calcium ions is accompanied by rapid stabilization obtained in the extruder wrapping material. When stabilization wrapper last two JV is voivodin agent, and to handle this agent in a spray condition.

When stabilization wrappers usually use solutions with two - or trivalent ions, while it is preferable to use a combination of the content obtained in the extruder tube of sodium alginate and who is in the bath with a solution of calcium ions. For stabilization of alginates often use the corresponding salt, in particular calcium chloride. This salt, however, reduces the rate of combustion is made in the form of a tube wrapper, and therefore according to the invention for the stabilization of alginates is more preferable to use acetate.

Partial precipitation of the alginate occurs in the extruder when adding it to a subcritical level of the precipitator, and the final after extrusion in the respective bath by increasing the level of the precipitator. To precipitate the alginate can be used and other methods, including processing of the extrudate in the bath electrolyte with high ion content or miscible with water, the solvent in which the insoluble alginate.

Another method of stabilizing the structure obtained in the extruder wrapping material described above for the binder, based on usage is storeimage his agent, and subsequent removal of the wrapping material dissolving agent or adding to it sequestrant.

These methods can be used sequentially, i.e. first the wrap to stabilize the deposition bath calcium ions contained soluble alginate. After that, the wrapper need to pass through a bath filled with the absorbing moisture agent, such as ethanol, and then by heating to the appropriate temperature remove the remaining liquid. In another embodiment, after the stabilization of the wrapper can be immediately subjected to drying one of the methods described above.

Given the speed of response and the lack of free space necessary for carrying out certain operations of the technological process, in particular stages of drying, the above-described methods of stabilization wrappers are very effective and will get the extrudate, having a suitable form.

The wrapper may have a rigid structure, however, it was found that the use as a binder of sodium alginate, from which precipitation is formed calcium alginate, and slow subsequent drying allow to produce and flexible wrappers. The advantage of the flexible Ober the ranks of operations, requiring the use of manual labor.

The duration of the stabilization wrapper, made in the form of an extruded tube, is one of the important factors determining the quality of the finished wrapper, and depends on a combination of cations and ions, the strength of the solution, which is coming out of the extruder tube, and from the time of the tube in an ionic bath.

To more effectively reduce the content of the various components in side stream smoke in the composition of the wrapping material can include special affect this process substances, such as magnesium oxide.

As a Smoking material in the present invention it is proposed to use a fine-cut tobacco, which may be a conventional blend of cut tobacco leaves and stems, which you can optionally add a certain amount of expanded tobacco. As a Smoking material in the proposed invention the Smoking product, it is advisable to use a fast burning tobacco type well support smoldering fire tobacco brand Maryland or modified tobacco brand Virginia, although in some cases you can use unmodified tobacco brand Virginia and used the s cut leaf tobacco is preferably at least 50%, more preferably 60%, most preferably 70%.

The rate of combustion of the Smoking products can also be brought to the required level by changing the number contained in the wrapper additives that improve its combustion, taking into account this and other properties of the wrapper and composition of tobacco or tobacco blend.

Proposed in the invention, the Smoking article may as tobacco contain one or more tobacco materials selected from reclaimed tobacco material, non-tobacco material and alternative Smoking materials. Thus, the composition of the Smoking material in addition to appropriate quantities of tobacco, non-tobacco Smoking material or mixtures thereof, may also include added thereto aerosol forming material. As a Smoking material you can use reconstituted tobacco or Smoking alternative materials are described, for example, in the application WO 96/07336, and, in particular, carbon-containing combustible substances, which are described in the application on pages 15-18, aerosol forming materials specified in the application on pages 19-22, and forming an aerosol of the heat sources described on pages 22-24, filler, which is described in the application WO we WO 97/32490 on page 2-6, as well as Smoking material described in the application WO 98/57556 (Smoking material containing an aerosol forming substance is not based multimolecular alcohol, tobacco in an amount up to 20 wt.%, binder in a quantity not exceeding 20 wt.%, and an inorganic filler in an amount of not more than 30 wt.%), while all of the above applications are fully incorporated in the present description as a reference. The content of reconstituted tobacco or Smoking alternative material in the proposed invention, the Smoking article can vary from 10 to 100 wt.% in terms of all Smoking material.

Smoking material is preferably wrapped in an inner wrapper, which is used as the porous material for wrapping bales of tobacco or porous cigarette paper. The inner wrapping material provides the necessary contact burning during Smoking tobacco material with an outer wrapper. The diameter of the wrapped inner wrapper of the rod of Smoking material slightly smaller than the inner diameter of the main or outer wrapper products for Smoking. Part of the inner wrapper may include a number of supporting combustion of poroshkoobraz substances.

Permeability (porosity) of the inner wrapper is preferably greater than 6000 units of Coresta, more preferably greater than 12000 units Coresta. The porosity of the inner wrapper partly determined by the fact that the adhesive used should not seep through the zipper.

Proposed in the present invention, a Smoking article preferably used together with conventional filters made from fibers of cellulose acetate. As filters can also be used to double or triple carbon-based filters.

Below the invention is described in more detail on the example of one of the variants of its possible implementation with reference to the accompanying drawings on which is shown:

in Fig.1 is proposed in the invention of the Smoking product, and Fig.2 - graphics changes during mass freely smoldering cigarettes with tobacco brand Virginia, one of which is proposed in the present invention the wrapper (curve 2) and the second basic wrapper (curve 1).

Smoking product 1 consists of the tobacco rod 2 enclosed in the wrapper 3 and connected to the filter 4 from fibers of cellulose acetate.

The wrapper 3 is made of a viscous mass obtained by mixing 60 ml of water with 100 g of dry material, consisting l) with an average particle size of 45 μm, 2.5% of calcium carbonate (inorganic additive that improves the properties of the ash) and 5% from trisalicylate (additive that promotes combustion wrapper). This mass ekstragiruyut in the piston extruder, extruding it through a die of the "torpedo" type with an outer diameter of 7.5 mm in the bath filled of 0.75 molar solution of calcium acetate. Obtained by the extrusion of the tube is kept in the solution for 10-60 s, then remove from the solution, cut along the length into pieces and dried in air at 60% relative humidity and a temperature of 22°C with the appropriate dimensions of the pallet. The circumference is made in this way the tube is about 23.5 mm, and wall thickness is about 0.5 mm, the moisture Content in the dried tube is about 2%.

At the same time on a conventional wrapping machine by wrapping the tobacco rod 2, containing a mixture of tobacco brand Virginia, porous wrapper with a porosity of about 12000 units Coresta used to wrap bales of tobacco, made the wrapped tobacco rod, the outer diameter of which provides a tight clamping of the rod to the inner walls of the outer extruded wrapper.

To obtain the data below in the Noi paper wrapper with a porosity of 80 units of Coresta. From the same tobacco mixtures were prepared Smoking material for cigarettes with the inner wrap of the usual material and the above-described outer wrapper, however, these cigarettes are a prototype of Smoking products proposed in the present invention. All cigarettes had a length of 57 mm and made of fibers of cellulose acetate filters of length 27 mm

Example 1

This example was compared between the control cigarettes and manufactured according to the above-described technology of cigarettes, which was the prototype of Smoking products proposed in the present invention. Weight burning tobacco and the circumference of the tobacco rod of the control cigarettes and cigarette-prototypes Smoking products proposed in the present invention, are listed in table 1.

Data on the composition of the main stream smoke (i.e., stream of smoke directly inhaled by the smoker when tightening) for these cigarettes are shown in table 2.

The contents of the various components in side-stream smoke for each of the tested cigarettes are shown in table 3. In table 4 the percentages refer to the difference in the content in side-stream smoke of various components of the control cigarettes and charoseth the content of the corresponding component in side stream smoke, produced when Smoking "prototype", less than in the side stream smoke produced when Smoking the reference cigarette.

Given in tables evidence suggests that side-stream smoke of cigarettes with the proposed invention the wrapper contains significantly fewer different components than in the side stream smoke of cigarettes with conventional paper wrapper. Proposed in the invention, the wrap 90% reduces the quantity of side stream smoke particles do not contain nicotine dry matter. In the cigarettes offered in the invention wrapper tobacco is used more efficiently, and despite a smaller number of burning tobacco offered in the invention of tobacco products with the appropriate content in the main stream smoke resinous compounds have a very rich aroma. Thus, the proposed invention in solution can significantly reduce the quantity of tobacco in the Smoking product with low content of resinous compounds produced when Smoking the smoke and great flavor.

Example 2

In this example, for the manufacture proposed in the invention wrappers for the same as in example 1, is replicalouis (organic binder), 20% of activated aluminum oxide (inorganic binder), 63.5% of particles of calcined (sintered) dioxide aluminum (ceramic filler) size of about 50 μm, 1-5% calcium carbonate (inorganic additive that improves the properties of the ash) and 5% potassium acetate (additive that improves the combustion wrapper).

In the manufacture of cigarettes (even one prototype proposed in this invention Smoking products) as a Smoking material used is the same as in example 1, the tobacco rod of a mixture of tobacco brand Virginia with conventional porous wrapper.

Table 5 provides data on the composition of the main and side stream smoke and specify the number of puffs for cigarette prototype proposed in the invention of Smoking products and its comparison with the above-described control cigarette with tobacco brand Virginia.

The numbers in parentheses indicate how the percentage content of the corresponding component in side stream smoke produced when Smoking cigarettes prototype with tobacco brand Virginia, compared with the side stream smoke produced when Smoking the reference cigarette (see table 3).

In Fig.2 in the form of graphs showing change is in the present invention. The total duration of the complete combustion of freely decaying conventional Smoking articles and Smoking articles proposed in the present invention, the same and is about 10 minutes During this time, however, expressed as a percentage loss of mass from the proposed invention in Smoking products less weight loss in the control cigarette. When Smoking the reference cigarette tobacco brands Virginia and described in example 1 cigarette prototype proposed in the invention of Smoking products consumed the same amount of tobacco.

Produced when Smoking is proposed in the invention of the cigarette ash is shaken with it, just as with regular cigarettes, and has acceptable color.

A reduction in the content of the various components in side-stream smoke has proposed in the present invention Smoking products due to mechanical capture of particles contained in the side stream smoke. This is mainly proposed in the invention of the zipper keeps water phase particles contained in the side stream smoke.

A significant advantage of the present invention Smoking articles in which the Smoking material ispolzovanie jet of smoke, formed during Smoking of cigarettes wrapped in a wrapper Smoking materials, do not contain tobacco. In other words, the proposed invention, the wrapper provides effective filtering of the various components formed during Smoking of side stream smoke.
