Description
SMOKING ARTICLE
FIELD OF THE INVENTION
The invention relates to a smoking article as defined in the preamble of claim 1 and to a method for preparing a smoking article as defined in the preamble of claim 16 and 21.
BACKGROUND OF THE INVENTION
It is very hard for a smoker to give up smok-ing entirely due to the addictive nature of nicotine in the tobacco. An acceptable alternative has been to arrange the nicotine in some other form or some other way instead of smoking.
Known articles used to replace cigarettes and/or to assist in giving up smoking include chewing gums, plasters, nasal sprays or lozenges with added nicotine.
A problem with these articles is that their use does not provide a smoking experience. Smokers want to have the actual smoking experience, whereby they want e.g. to feel the taste of tobacco and smoke in their mouth.
Patent publication US 7290549 discloses a smokeless smoking article. The smoking article con-tains tobacco and a smokeless chemical heat source that heats and volatilizes the tobacco providing the tobacco aroma or a tobacco-aromized aerosol. The heat chamber of the heat source comprises a heat cartridge which contains a chemical compound (such as magnesium and iron) capable of producing heat, and an activating solution (such as a solution of potassium chloride and nitrate) separated by a frangible partition. In the article, the heat producing reaction is provided by combining the heat cartridge and the activating solu-tion by breaking the partition.
A problem with the smokeless smoking article is the slow rising of the temperature to the optimum volatilization temperature region of tobacco, which is about 125 to 150 C. In addition, the smoking article requires that two separate chambers be combined to start the heat producing reaction.
Patent publication EP 0371285 discloses a smoking article comprising tobacco, a filter element and a heat source. The heat source contains material (e.g. metal oxides and anhydrous metal sulfates) which is capable of exothermic reaction when contacted with water. The contact between water and the components of the heat source forms heat which warms and volatilizes the tobacco. The water required in the reaction may be injected into the heat source, it may be incorporated in a separate rupturable capsule or it can be incorpo-rated in a solid salt, a salt hydrate.
Patent publication US 5285798 discloses a smoking article comprising tobacco, a filter element and a heat source. The chemical agents of the heat source, which comprise at least two metallic agents, interact electrochemically when contacted with an electrolyte solution, e.g. water. The electrochemical interaction produces heat which warms and volatilizes the tobacco.
A problem with the above-mentioned smoking articles is that the water which provides the exother-mic reaction must be separated from the co-reacting compounds in the smoking articles. These smoking arti-cles always require a separate water capsule, water injection or release of water from a hydrous salt to provide the exothermic heat producing reaction.
OBJECTIVE OF THE INVENTION
The objective of the invention is to disclose a new type of smokeless smoking article which is sim-ple in structure and operation and wherein the heat source quickly reaches the temperature of the optimum volatilization region of tobacco without a separate addition or chamber of liquid/water. A further objec-tive of the smoking article of the invention is to provide a smoking experience to the smoker without combusting tobacco or other ingredients, without out-side smoke and without generating any combustion prod-ucts, such as carbon monoxide. One specific objective of the invention is to alleviate the problems referred to above.
One further objective of the invention is to disclose a method for producing the smoking article.
SUMMARY OF THE INVENTION
The smoking article according to the inven-tion is characterized by what has been presented in claim 1.
The method for producing the smoking article according to the invention is characterized by what has been presented in claim 16 and 21.
The smoking article according to the inven-tion comprises tobacco, suction resistance and a chemical heat source in conjunction with the tobacco.
The chemical heat source comprises a heat chamber formed from one continuous volume and is activated by external thermal and/or oxygen excitation. The chemi-cal heat source is based on exothermic reaction.
The heat chamber may be closed.
The heat which is forming in the heat chamber reaches the preferred volatilization region of 125 to 150 C of tobacco quickly and keeps the temperature in this region. The heat volatilizes the aroma and nico-tine from the tobacco. The tobacco aroma and other ac-tive agents, such as nicotine, can be best released without combustion or production of smoke in the pre-ferred volatilization region.
The heat chamber contains chemical compounds which are capable of producing heat. The chemical com-pounds normally include a metal/metals and/or a strong oxygen-containing oxidizer. The metal may be a transi-tion metal, alkali metal, alkali earth and/or a metal of some other group. Examples of typical applicable metals include iron (Fe), aluminum (Al), magnesium (Mg), lithium (Li), cobalt (Co), platinum (Pt), palla-dium (Pd), copper (Cu), silicon (Si), preferably iron.
The strong oxygen-containing oxidizer may be a metal oxide, metal peroxide and/or metal oxide salt, for ex-ample potassium permanganate, manganese dioxide, lead-3-tetraoxide, barium peroxide, bromates, chlorates etc. The strong oxygen-containing oxidizer is prefera-bly potassium permanganate (KMnO4) or oxygen.
The chemical compounds are selected so as to produce a safe reaction and so that the temperature produced by the reaction rises quickly to the maximum temperature which is not too high, and so that the heat production in the reaction lasts for a long time.
In a preferred embodiment of the invention the chemical compounds are anhydrous.
The heat chamber may also contain a reaction catalyzing agent, for example carbon.
It is also possible to add inert filler mate-rial in conjunction with the chemical starting com-pounds in the heat chamber. The inert filler material may also contain typical additives, such as binder, which may for example accumulate heat.
The heat chamber is made from a material which holds the temperatures generated by the heat chamber reaction, and typically temperatures of about 220 C. Polymer-, paper-, natural fiber -, ceramic-, glass- and/or metal-based materials, which stand the temperature and pressure generated in the reaction and the compounds formed in the reaction, can be used for making the heat chamber. The polymer-based materials may include polypropylene, polyethylene, other poly-5 olefins, polyesters and/or other equivalent polymeric materials and/or mixtures thereof. The paper-based material may include paper and/or coated paper and/or other material based on natural fibers.
The material of the heat chamber is imperme-able to oxygen when oxygen is used as the oxidizer.
The heat chamber may be provided with a heat insulating and/or heat accumulating layer. The heat chamber is preferably provided with an insulating layer when it is made from heat-conducting material, such as for example aluminum. The insulating layer may be made from natural or synthetic polymeric material, such as textile, paperboard or polystyrene or from ce-ramic, glass- or metal-based material. The heat accu-mulating layer enables to obtain steady and longer-lasting optimum heat. The heat accumulating layer may be made for example from wax.
The external excitation which activates the heat source is heat and/or oxygen. The heat is pro-vided by fire for example using a match or a lighter, by electricity using for example an electrically heated resistance wire, by a detonator and/or other starting heat providing excitation. The applied oxy-gen may normally be oxygen contained in the air con-tacted with the heat source for example by breaking the wall of the airtight heat chamber which is imper-meable to oxygen, by removing, in a smoking article covered by a protective film/package that is imperme-able to oxygen, this film/package, and/or by contact-ing the heat chamber which is impermeable to oxygen with air in an equivalent manner.

SUMMARY OF THE INVENTION
The smoking article according to the inven-tion is characterized by what has been presented in claim 1.
The method for producing the smoking article according to the invention is characterized by what has been presented in claim 16 and 21.
The smoking article according to the inven-tion comprises tobacco, suction resistance and a chemical heat source in conjunction with the tobacco.
The chemical heat source comprises a heat chamber formed from one continuous volume and is activated by external thermal and/or oxygen excitation. The chemi-cal heat source is based on exothermic reaction.

The strong oxygen-containing oxidizer may be a metal oxide, metal peroxide and/or metal oxide salt, for ex-ample potassium permanganate, manganese dioxide, lead-3-tetraoxide, barium peroxide, bromates, chlorates etc. The strong oxygen-containing oxidizer is prefera-bly potassium permanganate (KMnO4) or oxygen.
The chemical compounds are selected so as to produce a safe reaction and so that the temperature produced by the reaction rises quickly to the maximum temperature which is not too high, and so that the heat production in the reaction lasts for a long time.
In a preferred embodiment of the invention the chemical compounds are anhydrous.
The heat chamber may also contain a reaction catalyzing agent, for example carbon.
It is also possible to add inert filler mate-rial in conjunction with the chemical starting com-pounds in the heat chamber. The inert filler material may also contain typical additives, such as binder, which may for example accumulate heat.
The heat chamber is made from a material which holds the temperatures generated by the heat chamber reaction, and typically temperatures of about 220 C. Polymer-, paper-, natural fiber -, ceramic-, glass- and/or metal-based materials, which stand the temperature and pressure generated in the reaction and the compounds formed in the reaction, can be used for making the heat chamber. The polymer-based materials may include polypropylene, polyethylene, other poly-5 olefins, polyesters and/or other equivalent polymeric materials and/or mixtures thereof. The paper-based material may include paper and/or coated paper and/or other material based on natural fibers.
The material of the heat chamber is imperme-able to oxygen when oxygen is used as the oxidizer.
The heat chamber may be provided with a heat insulating and/or heat accumulating layer. The heat chamber is preferably provided with an insulating layer when it is made from heat-conducting material, such as for example aluminum. The insulating layer may be made from natural or synthetic polymeric material, such as textile, paperboard or polystyrene or from ce-ramic, glass- or metal-based material. The heat accu-mulating layer enables to obtain steady and longer-lasting optimum heat. The heat accumulating layer may be made for example from wax.
The external excitation which activates the heat source is heat and/or oxygen. The heat is pro-vided by fire for example using a match or a lighter, by electricity using for example an electrically heated resistance wire, by a detonator and/or other starting heat providing excitation. The applied oxy-gen may normally be oxygen contained in the air con-tacted with the heat source for example by breaking the wall of the airtight heat chamber which is imper-meable to oxygen, by removing, in a smoking article covered by a protective film/package that is imperme-able to oxygen, this film/package, and/or by contact-ing the heat chamber which is impermeable to oxygen with air in an equivalent manner.
In one preferred embodiment of the invention, the heat source contains iron and potassium permanga-nate as the chemical compounds. Reaction between the staring materials is initiated by introducing starting heat to the mixture by a match, lighter, detonator and/or resistance wire. Oxygen is not required in starting the reaction.
Reaction rate and heat produced in the reac-tion can be adjusted by weight ratios of the chemical compounds. The weight ratio is also selected according to thermal conductivity of the coating material in the heat chamber.
In one preferred embodiment of the invention, the weight ratio between potassium permanganate and iron ranges from 5/95 to 95/5, preferably from 25/75 to 50/50 and is more preferably 30/70.
In a further preferred embodiment of the in-vention, the heat chamber contains iron, sodium sul-fide and carbon, which are contacted with each other in the presence of oxygen or air according to the fol-lowing reaction:
Na2S x H2O + C + Fe + CaO + 02 Na2SO4 + CaCO3 + FenOm (iron oxides) By the catalyzing effect of carbon, iron heats up and raises further the heat produced in the reaction. The sodium sulfide may be hydrous or anhy-drous. Calcium oxide reacts with the sodium suplhide crystal water and temperature produced in the reaction raises more quickly. Material of the heat chamber is impermeable to oxygen.
The tobacco may include one type of tobacco and/or a mixture of tobacco, which may have been proc-essed by the raw tobacco processing methods known in the tobacco industry. The tobacco and/or the mixture thereof may include tobacco which has been processed in many different ways, such as tobacco fine cut, to-bacco strands, tobacco flakes, tobacco dust, processed tobacco, extruded tobacco, reconstructed tobacco, to-bacco extracts and equivalent processed forms of to-bacco used in the tobacco industry. Tobacco extracts include for example tobacco essences, aromatic oils of tobacco, spray-dried and freeze-dried tobacco extracts and the corresponding tobacco extracts used in prepar-ing the tobacco raw material.
Also flavoring agents, such as menthol, va-nillin, cocoa, licorice, cinnamic aldehyde and the like, as well as tobacco aroma modifiers and other modifiers, additives and fillers used in producing to-bacco, and nicotine may be added to the tobacco.
The amount of nicotine included in the to-bacco of the smoking article is typically 0.1 to 1.0mg.
Suction resistance of the smoking article provides resistance when drawing on the cigarette, and the smoker is, in this manner, able to use the sucking rhythm to control his or her smoking rhythm. Suction resistance is preferably disposed at one end of the smoking article.
In a preferred embodiment of the invention, suction resistance is a filter which prevents the to-bacco from being contacted with the smoker and/or fil-ters any harmful products which are formed during volatilization of the tobacco, such as tar.
The smoking article may further comprise a heat-providing element in conjunction with the heat source used to activate the heat source. The heat-providing element may be a detonator whereby the heat chamber is activated for example by snapping the smok-ing article, or a resistance wire, for example wolf-ram, which heats up intensely when current is being conducted to the wire, a fuse and/or a firing tape to introduce the starting heat to the heat chamber.
The smoking article may further comprise a cooling part which cools down the fume drawn in and breathed by the user and formed by volatilization of the tobacco. The cooling part also enables one to ad-just the amount of fume deriving from the fine cut to-bacco. The flow section of the cooling part is equal or substantially smaller than the flow section of the smoking article. Adjusting the cross-section of the cooling part to be smaller than the cross-section of the smoking article reduces the amount of fume to be drawn in and extends the time of use of the smoking article. The cooling part is preferably disposed be-tween suction resistance and the tobacco.
Material of the cooling part includes any heat insulating and resistant material, preferably heat resistant plastic.
In one embodiment of the invention, the heat chamber is surrounded by the tobacco in the smoking article. The heat chamber may be a bar- or spiral-shaped, accordion-shaped or waved structure or one which has been folded in any other form. By shaping the structure of the heat chamber to the above-mentioned form it is possible to fit a longer heat chamber in the smoking article. A longer heat chamber provides steadier and longer lasting optimum heat and longer time of use for the smoking article.
In a further embodiment of the invention, the tobacco is surrounded by the heat chamber in the smok-ing article. The heat chamber is tubular.
The smoking article may be coated with to-bacco paper and/or other material which is similar to tobacco paper.
Surface of the tobacco paper may be treated with a colorant, such as thermochrome pigment which changes color by the effect of heat. This makes the cigarette look like burning.
The smoking article may be in the form of a substantially tubular/bar-shaped object of a substan-tially round cross-section. The cross-section may also be angular or flattened. The smoking article is pref-erably in the form of a traditional cigarette.
The smoking article is produced by forming the heat chamber by combining the chemical compounds and enclosing them inside the heat chamber, contacting a layer of tobacco with the heat chamber, disposing suction resistance at one end of the smoking article, and coating the heat chamber contacted with the layer of tobacco.
The heat chamber may be formed as a structure which is either substantially bar-shaped, spiral, ac-cordion-shaped, waved or folded in any other form, or as a tubular structure.
The layer of tobacco can be disposed to sur-round the heat chamber which is substantially bar-shaped, spiral, accordion-shaped, waved or folded in any other form, or inside the substantially tubular heat chamber.
Where required, a heat insulating and/or ac-cumulating layer is disposed between the heat chamber and the tobacco.
An insulating layer may be disposed, if nec-essary, onto the layer of tobacco or the heat chamber before coating or in conjunction with the coating. The smoking article is typically coated with tobacco pa-per.
If desired, a cooling part may be disposed at one end of the smoking article. The cooling part is preferably disposed between suction resistance and the tobacco.
The smoking article according to the inven-tion wherein the tobacco is surrounded by the heat 5 chamber can also be produced by gluing/fixing the re-action starting materials, the chemical compounds, on a planar structure which is rolled to form a tubular structure. A protective film, insulator and/or accumu-lating layer may be disposed onto the starting materi-10 als for example by lamination. The tobacco is disposed inside or outside the tubular structure. The planar structure may be formed by tobacco paper, an insulat-ing layer and/or heat-accumulating layer.
Production of the heat source requires a sub-stantially oxygen-free atmosphere including for exam-ple nitrogen, carbon dioxide or argon gas when oxygen is used as the external heat source excitation. The production is carried out as a batch process. In this case, the chemical compounds are mixed and the heat chamber seamed in an entirely closed oxygen-free space filled with nitrogen or argon gas. Airtightness should be maintained from production to the user. The smoking article may be packed in an airtight individual pack.
The smoking article according to the inven-tion is immediately ready to use when the smoker acti-vates the exothermic heat chamber reaction by the starting heat or oxygen. The temperature of the heat chamber quickly rises to the volatilization tempera-ture of tobacco and volatilizes nicotine and aromas of the tobacco and/or flavoring agents added to the to-bacco. The smoker is able to sense the volatilized nicotine and aromas of the tobacco and have the smok-ing experience without smoke when drawing in tobacco through the filter. The heat chamber produces heat sufficiently and quickly to volatilize the components of the tobacco while maintaining the temperature in the preferred volatilization region for minutes. The smoking article and its heat chamber are simple is structure and operation. No combining of chemical com-pounds with water for example by injecting water into the heat chamber, breaking a separate liquid capsule or using hydrous salts is required in the production of energy in the heat chamber. When handled, the smok-ing article feels the same as a real smoking article, such as a cigarette or cigar, and has the same visual appearance. In addition, the smoking article has good storage endurance. Reaction products of the smoking article are not toxic and can be safely disposed of with normal household waste.

DETAILED DESCRIPTION OF THE INVENTION
Reaction rate and heat produced in the reac-tion can be adjusted by weight ratios of the chemical compounds. The weight ratio is also selected according to thermal conductivity of the coating material in the heat chamber.
In one preferred embodiment of the invention, the weight ratio between potassium permanganate and iron ranges from 5/95 to 95/5, preferably from 25/75 to 50/50 and is more preferably 30/70.

A protective film, insulator and/or accumu-lating layer may be disposed onto the starting materi-10 als for example by lamination. The tobacco is disposed inside or outside the tubular structure. The planar structure may be formed by tobacco paper, an insulat-ing layer and/or heat-accumulating layer.
Production of the heat source requires a sub-stantially oxygen-free atmosphere including for exam-ple nitrogen, carbon dioxide or argon gas when oxygen is used as the external heat source excitation. The production is carried out as a batch process. In this case, the chemical compounds are mixed and the heat chamber seamed in an entirely closed oxygen-free space filled with nitrogen or argon gas. Airtightness should be maintained from production to the user. The smoking article may be packed in an airtight individual pack.
The smoking article according to the inven-tion is immediately ready to use when the smoker acti-vates the exothermic heat chamber reaction by the starting heat or oxygen. The temperature of the heat chamber quickly rises to the volatilization tempera-ture of tobacco and volatilizes nicotine and aromas of the tobacco and/or flavoring agents added to the to-bacco. The smoker is able to sense the volatilized nicotine and aromas of the tobacco and have the smok-ing experience without smoke when drawing in tobacco through the filter. The heat chamber produces heat sufficiently and quickly to volatilize the components of the tobacco while maintaining the temperature in the preferred volatilization region for minutes. The smoking article and its heat chamber are simple is structure and operation. No combining of chemical com-pounds with water for example by injecting water into the heat chamber, breaking a separate liquid capsule or using hydrous salts is required in the production of energy in the heat chamber. When handled, the smok-ing article feels the same as a real smoking article, such as a cigarette or cigar, and has the same visual appearance. In addition, the smoking article has good storage endurance. Reaction products of the smoking article are not toxic and can be safely disposed of with normal household waste.

DETAILED DESCRIPTION OF THE INVENTION
The smoking article (1) according to Fig. 1 is formed as a cigarette. The smoking article com-prises a substantially bar-shaped heat source (2), which is a closed heat chamber surrounded by a layer of tobacco (3). At one end of the smoking article there is suction resistance (4) which is normally a filter. The heat source (2) contains chemical com-pounds which provide an exothermic reaction, prefera-bly an oxidizable metal Fe and a strong oxygen-containing oxidizer KMnO4. The compounds of the heat chamber may be present in an inert filler. The smoking article (2) has been coated with tobacco paper (7).
In the smoking article (1) according to Fig.
2 tobacco (3) is surrounded by the bar-shaped closed heat source (2) . In other respects, the smoking arti-cle is similar to that described above.
In the smoking article (1) of Fig. 3 and 4 a heat accumulating layer (5) has been disposed between the heat source (2) and the layer of tobacco (3), re-leasing heat more steadily and maintaining the tem-perature for a longer period of time in the desired volatilization region of tobacco. The heat accumulat-ing layer (5) is a layer that contains for example metal, such as aluminum. Further, the layer of tobacco (3) has been coated with a heat insulating layer (6), for example a polystyrene-based material, which has low ability of conducting heat, so that the cigarette would not feel too hot in the hand.
Instead of the heat accumulating layer (5) there may be disposed, in the position of the layer or in conjunction with the layer, a heat insulating layer, if the material of the heat chamber is heat conductive and/or the reaction of the heat chamber produces heat which exceeds the volatilization tem-perature of tobacco.
In the smoking article (1) according to Fig.
2 tobacco (3) is surrounded by the bar-shaped closed heat source (2) . In other respects, the smoking arti-cle is similar to that described above.
In the smoking article (1) of Fig. 3 and 4 a heat accumulating layer (5) has been disposed between the heat source (2) and the layer of tobacco (3), re-leasing heat more steadily and maintaining the tem-perature for a longer period of time in the desired volatilization region of tobacco. The heat accumulat-ing layer (5) is a layer that contains for example metal, such as aluminum. Further, the layer of tobacco (3) has been coated with a heat insulating layer (6), for example a polystyrene-based material, which has low ability of conducting heat, so that the cigarette would not feel too hot in the hand.
Instead of the heat accumulating layer (5) there may be disposed, in the position of the layer or in conjunction with the layer, a heat insulating layer, if the material of the heat chamber is heat conductive and/or the reaction of the heat chamber produces heat which exceeds the volatilization tem-perature of tobacco.
Alternatively, in the smoking article accord-ing to Fig. 3 and 4, the heat source (2) may be dis-posed in the position of the tobacco (3) and the to-bacco (3) in the position of the heat source (2) . In this case, the tobacco is surrounded by the heat source and the heat accumulating layer (5) is disposed between them. In addition, the heat source is coated by a heat insulating layer (6).
In the smoking article (1) according to Fig.
6 the bar-shaped heat source (2) has been bent to a spiral form and the heat source is surrounded by the tobacco (3) . A longer heat chamber keeps the tempera-ture longer in the desired volatilization region.
In the smoking article (1) according to Fig.
7 the bar-shaped heat source (2) has been folded in accordion form and the heat source is surrounded by the tobacco (3) . Disposed between suction resistance (4) at one end of the smoking article and the part which forms the tobacco (3) and the heat chamber (2) there is a cooling part (8) which is smaller in cross-section than the smoking article and cools down the fume that passes through it volatilizing from the to-bacco, reducing the amount of fume drawn in and thereby extending the time of use of the smoking arti-cle. The cooling part (8) is normally made from heat resistant plastic. The section (9) which surrounds the cooling part (8) normally contains air.
The cross-section of the cooling part (8) may also be equal to that of the smoking article, in which case the cooling part merely cools down the fume that volatilizes from the tobacco to be suitable for the user.
In the smoking article (2) according to Fig.
8 the heat chamber (3) has been formed by combining three bar-shaped heat chambers. A longer heat chamber provides longer time of use.

In the smoking article (2) according to Fig.
8 the heat chamber (3) has been formed by combining three bar-shaped heat chambers. A longer heat chamber provides longer time of use.
Example 1 The effect of the chemical compounds, start-ing materials, of the heat chamber on the exothermic reaction was tested in the experiments. Weight ratios of different starting materials were used in the tests to establish their effect on the heating rate, maximum temperature and temperature changes in the course of time. The heating tests were conducted with the reac-tion of potassium permanganate and iron in weight ra-tios of 30/70 and 70/30. A starting material mixture of 1.0g was used in the tests. The reactions were con-ducted by positioning the starting materials in alumi-num or glass tubes, whereupon the reaction was actu-ated by an electric fuse. The temperature was followed by a thermoelement attached to the tube.
The tubes fitted inside the fine cut tobacco part of a normal-size cigarette in such manner that space was left for the fine cut tobacco. The internal and external diameter and wall thickness of the alumi-num and glass tubes were: Al 4.75mm, 4.05mm and 0.35mm: glass 5.06mm, 3.06mm and 1mm. The tube length was 55mm, which is suitable for a rolling machine with filter.
The results of the conducted heating tests are shown in Fig. 5.
The results indicate that in all tests the temperature rose to the optimum volatilization region of tobacco in less than 20 seconds.
The weight ratio of 70/30% Kmn04/Fe produced clearly too high a temperature, in particular if one intends to use paper as the wrapper. This weight ratio requires the use of an insulating layer.
The weight ratio of 30/70% Kmn04/Fe was com-pared in the glass tube, aluminum tube and insulated glass tube. According to the results, the glass tube kept the heat longer than the aluminum tube and the maximum temperature rose about 50 C higher.
Insulating the glass tube with an aluminum 5 foil covered by a thin fabric delayed the time of reaching the maximum temperature for a few dozen sec-onds. Reaching the volatilization region was delayed by about 10s, but the temperature was maintained above this region 2.5 times longer than with the non-10 insulated tube, i.e. for about 2 minutes.
Example 2 The functionality of the smokeless smoking 15 article was tested in the experiment. Insulated glass tube was used as the heat chamber structure. The structure was similar to that of Example 1. The thick-ness of the insulating layer formed by the aluminum foil and the fabric was 0.56mm.
1.0g of a mixture of potassium permanganate and iron (30/70) was introduced into the heat chamber.
The smoking article was produced by placing the heat chamber into a rolling machine with tobacco paper, filter and tobacco fine cut and by rolling the smoking article.
Reaction starting heat was introduced to the smoking article by a resistance wire which was heated by conducting electric current to the wire.
After the test, the smoking article was exam-ined visually and it was observed that tar had been separated from the tobacco onto the paper surface.
From the filter it was visible that the heat chamber reaction had separated ingredients from the fine cut tobacco. There was no observed burning or blackening of the fine cut tobacco in the cigarette when opened after the test.

The test proved that by the contrived heat chamber composition and structure it is possible to volatilize the tobacco aroma and nicotine from the to-bacco in the smoking article.
Example 3 The test comprised analyzing the volatile elements of the smokeless smoking article according to the invention, a normal cigarette and a commercial smokeless smoking article: nicotine, carbon monoxide (CO) and tar. The smoking article according to Example 2 was used as the smokeless smoking article and Philip Morris "Gold" Marlboro as the normal cigarette. A
smoking article according to Woodleaf Corporation brand Aeros was used as the commercial smokeless ref-erence smoking article, which is based on a plastic tube that has been seamed at both ends and contains a matrix including nicotine and tobacco aroma. The smoker cuts off the ends of the plastic tube, and nicotine and tobacco aroma are released into the mouth and organs of the smoker when drawing in air through the tube.
Nicotine and tar components were determined by a GC-MS-apparatus and carbon dioxide by a GC-TDC-apparatus. Two parallel assays were conducted for the cigarettes. The results of the smoking article accord-ing to the invention (SAI) have been scaled to the amount of fine cut tobacco in a normal cigarette. The results have been assembled in Table 1.
