FIELD OF THE INVENTION AND TOBACCO PRODUCT AND METHOD FOR MANUFACTURING IT

The invention relates to a tobacco product as defined in the preamble of claim 1 and to a method for producing a tobacco product as defined in the preamble of claim 5.

BACKGROUND OF THE INVENTION

It is extremely difficult for a smoker to quit tu-10 completely due to the nicotine addictive nature of tobacco. An acceptable alternative has been to provide nicotine in some other form or other way than smoking.

Known products that are used as a tobacco substitute and / or to help stop smoking are chewing gums, patches, nasal sprays or lozenges to which nicotine has been added.

The problem with these products is that using these products does not result in a smoking experience. Smokers want to experience the experience of living in a private house where they want, for example. feel the taste of tobacco and smoke in your mouth.

US 7290549 discloses 25 smokeless tobacco products. The tobacco product contains a tobacco and a non-smoking chemical heat source that heats and vaporizes the tobacco to provide a tobacco flavor or a tobacco-flavored aerosol. The heat source heat chamber comprises a heat cartridge containing a chemical compound (such as magnesium and iron) capable of producing heat and an activating solution (such as potassium chloride and nitrate solution) separated by a decomposing septum. The heat-producing reaction in the product is accomplished by combining the heat cartridge and the activation solution 35 by disintegrating the septum.

2

The problem with a smokeless tobacco product is the slow rise in temperature to the optimum vaporization temperature range of the tobacco, which is about 125-150 ° C. In addition, the tobacco product requires the combination of two separate chambers to initiate a heat-producing reaction.

PURPOSE OF THE INVENTION

It is an object of the present invention to provide a novel non-smoking tobacco product of 10 types, simple in structure and function, the heat source of which quickly reaches the temperature of the optimal vaporization area of the tobacco. A further object of the tobacco product of the invention is to provide the smoker with a smoking experience without burning of the tu-15 stack or other ingredients, without external smoke and without the formation of combustion products such as carbon monoxide. In particular, it is an object of the invention to alleviate the above problems.

It is a further object of the invention to provide a method for making a tobacco product.

SUMMARY OF THE INVENTION

The tobacco product of the invention is characterized in what is set forth in claim 1.

The method of manufacturing a tobacco product according to the invention is characterized in what is set forth in claim 15.

The tobacco product of the invention comprises a tu-pack, a suction resistor, and a chemical heat source disposed with the tobacco. The chemical heat source comprises a heat chamber and is activated by an external excitation. Chemical heat source based on exothermic reaction 35 The heat chamber may be closed.

The heating chamber consists of a uniform space.

3 The heat generated in the heating chamber quickly reaches the preferred vaporization range of the tobacco at 125-150 ° C and maintains the temperature within this range. The heat vaporizes the tobacco aroma and nicotine. Tobacco aroma 5 and other active ingredients such as nicotine are best dispensed in a convenient vaporization zone without burning and producing smoke.

The heat chamber contains chemical compounds that are capable of producing heat. The chemical compounds are usually metal / metals and / or strong oxygen containing oxidant. The metal may be transition metal, alkali metal, alkaline earth metal, and / or other group metal. Examples of common metals used are iron (Fe), aluminum (Al), magnesium (Mg), lithium (Li), cobalt (Co), platinum (Pt), palladium (Pd), copper (Cu), silicon (Si ), preferably iron. The strong oxygen-containing oxidant may be metal oxide, metal peroxide and / or metal oxide salt, for example potassium permanganate, manganese dioxide, lead-3-tetraoxide, barium peroxide, bromates, chlorates, etc. The strong oxygen-containing oxidant is preferably potassium permanganate or oxygen.

The chemical compounds are chosen so that the reaction between them is safe, the temperature of the reaction quickly rises to a maximum temperature which is not too high, and the heat production in the reaction is maintained for a long time.

The heating chamber may further comprise a reaction catalyst, for example carbon.

30 Inert filler material may also be added to the chemical starting compounds of the heating chamber. The inert filler material may further contain conventional additives such as a binder which may, for example, retain heat.

35 The furnace is made of a material which is capable of withstanding the temperatures generated by the reaction of the furnace and typically about 220 ° C. Polymer, paper, natural fiber, ceramic, glass and / or metal based materials that can withstand the temperature, pressure and compounds formed in the reaction can be used to make the heating chamber 4. Polymer-5-based materials may include polypropylene, polyethylene, other polyolefins, polyesters and / or other similar polymeric materials and / or mixtures thereof. The paper-based material may be paper and / or coated paper and / or other natural non-woven material.

The heat chamber material is oxygen impermeable when the oxidant is oxygen.

The heat chamber may be provided with a heat insulating and / or heat reservoir layer. It is advantageous to provide the thermal chamber with an insulating layer when the thermal chamber is made of a heat-conductive material such as aluminum. The insulating layer may be of natural or synthetic polymeric material such as textiles, cardboard or polystyrene or ceramic, glass or metal based material. The heat-accumulating layer provides an even and longer-lasting optimum heat. The heat retaining layer may be, for example, wax.

The external excitation activating the heat source is heat and / or oxygen. The heat is produced by fire, for example by using a match or a lighter, electrically by means of, for example, an electrically heated resistor wire, by a trigger and / or by some other heat generating excitation. As oxygen, conventional oxygen in the air can be used, which is contacted with the heat source, for example by breaking the wall of an airtight, oxygen-impermeable heat chamber, removing the tobacco product protected by an oxygen-impermeable protective film / packaging and / or head impermeable heat chamber for contact with air.

5

In a preferred embodiment of the invention, the chemical chamber contains iron and potassium permanganate as chemical compounds. The reaction between the starting materials is initiated by introducing an initial heat of the mixture into the mixture, with a lighter, a detonator and / or a resistance wire. The reaction does not require oxygen to start.

The rate of the reaction and the heat it produces can be controlled by the weight ratios of the chemical compounds. The weight ratio is also selected on the basis of the thermal conductivity of the material of the heating chamber casing 10.

In a preferred embodiment of the invention, the weight ratio of potassium permanganate to iron is 5/95 to 95/5, preferably 25/75 to 50/50 and more preferably 30/70.

In another preferred embodiment of the invention, the heating chamber contains iron, sodium sulfide and carbon which are contacted in the presence of oxygen or air according to the following reaction:

Na 2 S x H 2 O + C + Fe + CaO + 02 -> 20 Na 2 SO 4 + CaCO 3 + PhenOm (iron oxides)

Due to the catalytic action of carbon, the iron warms up and raises the heat of the reaction higher. Sodium sulfide may be anhydrous or anhydrous. Calcium oxide reacts with sodium sulfide in water and the reaction temperature rises faster. The material of the heating chamber is oxygen-impermeable.

The tobacco may be of a single tobacco quality and / or a blend of tobacco which may have been subjected to the processing of raw tobacco known in the tobacco industry. The tobacco and / or mixture thereof may contain tobacco processed in various ways such as tobacco chips, tobacco filaments, tobacco strips, tobacco dust, processed tobacco, 35 extruded tobacco, reconstituted tobacco, tobacco extracts and the like in the manufactured tobacco industry. Tobacco extracts 6 include, for example, tobacco essences, tobacco aroma oils, spray-dried and freeze-dried tobacco extracts, and similar tobacco extracts used in the manufacture of tobacco raw materials.

Flavoring agents such as menthol, vanillin, cocoa, liquorice, chalaldehyde and the like as well as tobacco flavor modifiers and other modifiers, additives and excipients used in the manufacture of tobacco as well as nicotine may also be added to tobacco.

The amount of Nikootin present in the tobacco of the tobacco product is usually from 0.1 to 1.0 mg.

The suction resistance of the tobacco product provides resistance to smoking and the smoker can thus control his / her smoking rate at the suction rate. Preferably, the suction resistor is located at one end of the tobacco product.

In a preferred embodiment of the invention, the suction resistor is a filter that prevents tobacco from coming into contact with the smoker and / or filters harmful products such as tar formed by vaporization of the tobacco.

The tobacco product may further comprise a heat generating element disposed along with the heat source, which is used to activate the heat source. The warm-25 tab generating element may be a teddy, whereby the heat chamber is activated by, for example, tapping a tobacco product, or a resistance wire, for example tungsten, which heats vigorously when power is applied to the ignition and / or fire wire.

In one embodiment of the invention in the tobacco product, the tobacco surrounds the thermal chamber. The heating chamber is rod-shaped.

In another embodiment of the invention, in the tobacco-35 product, the heating chamber surrounds the tobacco. The heating chamber is tubular.

7

The tobacco product may be coated with tobacco paper and / or other tobacco-like material.

The surface of the tobacco paper can be treated with a dye-5 such as a thermochrome dye that changes color due to heat. This makes the tobacco look flammable.

The tobacco product may have a substantially tubular / rod-shaped body having a substantially circular cross-section. The cross-section may also be angular or flattened. The tobacco product is preferably in the shape of a traditional cigarette.

The tobacco product is prepared by forming a heat chamber by combining the Kemi-15 compounds and enclosing them in the heat chamber, either in a substantially rod-shaped or tubular structure,

If necessary, a heat insulating and / or reservoir layer is placed between the heat chamber and the tobacco.

If necessary, an insulating layer may be placed on the tobacco layer or the heating chamber before or during coating. The tobacco product is usually coated with tobacco paper.

The tobacco product of the invention, wherein the tobacco chamber surrounds the tobacco, can also be made by gluing / attaching the reaction starting materials, chemical compounds, to a planar structure which is wrapped in a tubular structure. The starting materials may, for example, be laminated with a protective film, an insulator and / or a charge layer. The tobacco is placed inside or outside the tubular structure. The planar structure 8 may consist of a tobacco paper, an insulating layer and / or a heat-retaining layer.

The preparation of the heat source requires a substantially oxygen-free atmosphere including, for example, nitrogen-5 carbon dioxide or argon when the external excitation of the heat source is oxygen. Manufacturing takes place as a batch process. In this case, the mixing of the chemical compounds and the sealing of the heating chamber is carried out in a completely closed nitrogen or argon gas-filled, anoxic state. Airtightness must be maintained from manufacture to user. The tobacco product may be packed in airtight individual packaging.

The tobacco product of the invention is readily ready for use when a smoker activates an exothermic reaction of the thermal chamber with initial heat or oxygen. The temperature of the heating chamber rises rapidly to the vaporization temperature of the tobacco and evaporates the nicotine and flavorings and / or flavorings added to the tobacco. The Tu-20 packer is able to sense the vaporized Niko of the tobacco and the flavoring and experience a smokeless smoking experience as he sucks the tobacco through the filter. The heat chamber provides sufficient and rapid heat to vaporize the tobacco components while maintaining the temperature within the preferred vaporization range for minutes. A tobacco product feels the same when treated as a real tobacco product such as a cigarette or cigar and visually looks the same. In addition, the tobacco product is resistant to storage. The reaction products of the tobacco product are non-toxic and can be disposed of safely with normal household waste.

DETAILED DESCRIPTION OF THE INVENTION

The tobacco product (1) of Figure 1 is cigarette-shaped. The tobacco product has a substantially tan-like heat source (2), which is a closed heat chamber 15 surrounded by a tobacco layer (3). At the other end of the tobacco product is a suction resistor (4), which is usually a filter. The heat source (2) contains exothermic chemical compounds, preferably oxidizable metal Fe and strong oxygen-containing oxidant KMnO4. The compounds of the thermal chamber may be located in an inert filler. The tobacco product (2) is coated with tobacco paper (7).

In the tobacco product (1) of Fig. 2, a rod-shaped closed heat source (2) surrounds the tobacco 25 (3). Otherwise, the tobacco product is as described above.

In the tobacco product (1) of Figures 3 and 4, a heat-retaining layer (5) is disposed between the heat source (2) and the tobacco layer (3), which distributes heat more evenly and maintains the temperature for longer over the desired vaporization area of the tobacco. The heat-retaining layer (5) is, for example, a layer containing a metal such as aluminum. The tobacco layer (3) is further coated with a heat-insulating layer (6), for example, on a polystyrene-based material which poorly conducts heat 35 so that the cigarette does not feel too hot in the hand.

Instead of the heat-retaining layer (5), a heat-insulating layer may be placed in its place and / or adjacent thereto if the material of the heat-chamber is electrically conductive and / or the heat-chamber reaction produces 5 heat above the vaporization temperature of the tobacco.

Alternatively, the heat source (2) may be located in the position of the tobacco (3) and the tobacco (3) in the position of the heat source (2) in the tobacco product of Figures 3 and 4. In this case, the heat source surrounds the tobacco and a heat storage layer (5) is located between them. In addition, the heat source is coated with a heat insulating layer (6).

Example 1 In experiments, the effect of chemical compounds of the thermal chamber, the starting materials, on the exothermic reaction was tested. The weight ratios of the various starting materials were used in the experiments to determine their effect on warming speed, maximum temperature, and temperature change over time. Warming tests were carried out by reaction of potassium permanganate and iron in weight ratios of 30/70 and 70/30. 1.0 g of the starting material mixture was used in the experiments. Reactions were accomplished by placing the starting materials in aluminum or glass tubes, followed by reaction with an electric lighter. The temperature was monitored with a thermocouple attached to the tube.

The tubes fit inside a puff portion of normal sized tobacco, leaving room for tobacco chews. The inner and outer diameter and wall thickness of the aluminum and glass tubes were: Al 4.75 mm, 4.05 mm and 0.35 mm for glass 5.06 mm, 3.06 mm and 1 mm. The tubes were 55 mm long, which is suitable for a tobacco wrapping machine with a filter.

The results of the warming tests performed are shown in Figure 5.

11

The results show that in all experiments the temperature rose to the optimum vaporization range of the tobacco in less than 20 seconds.

The weight ratio of 70/30% KmnO4 / Fe clearly produced 5 too hard heat, especially if paper is to be used as a wrapper. This weight ratio requires the use of an insulating layer.

The weight ratio of 30/70% KmnO4 / Fe was compared in glass tube, aluminum tube and insulated glass tube 10. Based on the results, the glass tube retained heat longer than the aluminum tube and the peak temperature rose to about 50 ° C higher.

Insulating the glass tube with a thin cloth covered aluminum foil delayed the peak temperature by a few tens of seconds. Achieving the evaporation range was delayed by about 10 s, but the temperature remained at that level. above the area 2.5 times longer than with an uninsulated tube, ie about 2 minutes.

Example 2

The test tested the functionality of a smokeless tobacco product. The heat chamber was constructed of insulated glass tube. The structure was the same as in Example 25 cat 1. The thickness of the aluminum foil and fabric insulation layer was 0.56 mm.

1.0 g of a mixture of potassium permanganate and iron (30/70) was placed in the heating chamber.

The tobacco product was prepared by placing a heat-30 chamber in a tobacco wrapping machine with tobacco paper, a filter and tobacco debris, and wrapping the tobacco product.

The initial heat of the reaction was introduced into the tobacco product by a resistance wire which was heated by applying 35 electric currents.

After the test, the tobacco product was visually inspected and it was found that the tobacco had 12 tars on the surface of the paper. It was seen from the filter that the tobacco chamber had removed the tobacco smoke constituents. No tobacco burn or blackening was observed in the tobacco opened after the test.

5 The experiment showed that the composition and structure of the developed heating chamber allow the tobacco product to smell the tobacco aroma as well as the nicotine.

The invention is not limited solely to the above exemplary embodiments, but many modifications are possible within the scope of the inventive idea defined by the claims.
