Description

Smoking articles with heated compartments, including tobacco products

The present invention relates to smoking articles in the field of non-combustion heated products with heating compartments, including tobacco products for an intense smoking experience rich in tobacco flavor. The present invention also relates to a method for manufacturing the aforementioned smoking article.

There are many types of non-combustion heated products on the market. Most of these use a battery operated heating system to heat the cigarettes in a heating compartment. This heats the tobacco leaves at a lower temperature than conventional cigarettes. When the cigarette starts to heat up, the smoker can inhale an aerosol containing nicotine and other chemicals.

The lower temperature results in a less rich taste than conventional cigarettes during the smoking experience. As a result, smokers often criticize the poor taste of heated rather than burnt products. This problem is often mitigated by adding flavor to cigarettes, but smokers usually do not want any flavor other than cigarettes.

For example, US20040020504A1 discloses a side stream smoke cigarette comprising a conventional tobacco rod and combustible treatment paper containing a side stream smoke treatment composition. The wrapping paper is sprayed with the treatment composition to coat the wrapping paper.

In addition, CN105002785A discloses a cigarette lining paper in which the surface of a base paper is coated with a coating solution containing tobacco extract as a main solute. This document also discloses cigarette wrappers to prevent moisture, mold and aroma loss.

It would be desirable to provide a smoking article that allows a smoker to conveniently and effectively add desired tobacco flavor to an aerosol prior to inhalation. It would be particularly desirable if such smoking articles could be configured to allow the smoker to choose from a variety of tobacco flavors and flavor intensities. Desirably, such smoking articles should be capable of being manufactured on common handling machines.

Accordingly, an object of the present invention is to provide a non-combustion heating type smoking article rich in tobacco taste and a method for manufacturing the above-mentioned smoking article. Accordingly, the smoking experience may be similar to conventional cigarettes.

The aforementioned problems are solved by a smoking article having a distal end and a mouth end. The smoking article has a cylindrical shape and extends in the circumferential and longitudinal directions. at least one heating section comprising tobacco and/or reconstituted tobacco binder (RTB), at least one cooling section comprising a cylindrical cooler material, and a filter section along the longitudinal direction from the distal end to the mouth end; positioned to form a flow path from the distal end to the buccal end. The heating section, cooling section and filter section are at least partially surrounded by a first wrapper, the heating section including at least one second wrapper. The smoking article is characterized in that the second paper sheet is coated with a tobacco product including tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles.

Application of a tobacco product comprising tobacco particles to the second wrapper of the heating compartment enhances the smoker's tobacco taste experience. When the second wrapper is heated, the tobacco particles are inhaled together with the actual tobacco aerosol. This further enhances the tobacco taste. Preferably, the degree of enhancement of tobacco flavor through the addition of tobacco product can be controlled by the amount of tobacco product.

Tobacco particles having a very small average particle size provide a high surface area, which can be contacted by an aerosol. This allows the molecules of the particles to be transferred into the aerosol stream. Particle sizes below 30 μm have been found to allow a large number of flavoring molecules to be delivered, contributing to a rich tobacco flavor. This particle size allows larger or smaller molecules to migrate from the particle's interior volume to the surface, from which the molecules can then be transferred to the aerosol stream.

In the context of the present invention, the term "tobacco product" also refers to a flavoring material comprising tobacco particles having an average particle size (sD50 laser diffraction) of less than or equal to 30 μm.

Nicotine can also be transferred from tobacco particles to aerosols in a similar manner. Since nicotine has a flavor and is usually a component of tobacco, the term “flavor molecule” also includes nicotine.

This particle characteristic can also be explained by the rapid heating of the small particles after contact with the hot aerosol stream, which initiates flavor molecule migration within the tobacco particle. Flavoring molecules can also reach the particle surface and be rapidly transported into the aerosol stream, regardless of their location within the particle.

Preferably the average size of the tobacco particles (sD50 laser diffraction) is 1 μm or more, preferably 2.5 μm or more, more preferably 5 μm or more and most preferably 8 μm or more. It has been found that grinding tobacco particles to a smaller particle size can affect flavor. It is known that some of the flavor molecules in leaf tobacco are degraded due to high shear energy. Additionally, during the grinding process and subsequent handling, some flavor molecules escape from very small tobacco particles. As a result, these flavor molecules in the tobacco particles are depleted, resulting in a flavor composition that differs from the rich tobacco flavor.

It has been found advantageous to reduce the viscosity of the grinding composition to prevent degradation of the flavor molecules during the grinding process. This can be achieved by adding a solvent to the composition. This solvent (or "dispersion medium") is preferably selected from the group consisting of water, monohydric alcohols, polyhydric alcohols, sugar alcohols, sugars, and polyhydric alcohol esters. By using this dispersion medium, the average particle size of the tobacco can be adjusted to a desired value without significantly changing the flavor.

Tobacco products contain, in addition to tobacco particles having an average particle size of 30 micrometers or less, preferably a liquid medium such as alcohol or water in which the tobacco particles are dispersed.

In a preferred embodiment, the tobacco particles are liquid at a temperature below 30°C, preferably below 20°C, more preferably below 15°C, most preferably below 10°C to prevent loss of tobacco flavor and/or degradation. dispersed in the medium. Preferably the liquid medium of the dispersion has a temperature of -20°C or higher, preferably -10°C or higher, more preferably -5°C or higher and most preferably 0°C or higher for ease of handling. Cold dispersions with temperatures in the aforementioned range have also been shown to prevent nicotine degradation.

According to another embodiment, the smoking article is characterized in that the tobacco product is disposed on the inner surface and/or the outer surface of the second wrapper.

The tobacco product is mixed with an excipient liquid, preferably water, propylene glycol or glycerin, to suit the printing device. The specific formulation depends on the printing technique used.

In general, a pattern refers to a visible surface picture or surface structure. Preferably, the pattern consists of minimal repeatability (periodicity) and symmetry of coated and uncoated sections. The periodicity of the coated and uncoated compartments is preferably dependent on the degree of tobacco flavor enhancement desired. Preferably, the tobacco product is applied to the second wrapper of the smoking article, resulting in the formation of a coated compartment. Preferably, a visible ink containing tobacco product is applied to the coated section of the second paper.

It is possible to vary the distance between the coated and uncoated compartments. If a strong tobacco taste is desired, the distance between the coated and uncoated compartments is preferably on the order of the size of at least one coated compartment. It is also possible for the distance between the coated and uncoated compartments to be the size of at least a part of the coated compartment.

By using a darker colored tobacco type, a darker ink color is preferably obtained. These darker colored tobacco types are preferably Burley tobacco, dark fire-cured tobacco and dark air-cured tobacco. The use of these darker colored tobacco types preferably results in a darker ink color and higher color contrast for light colored wrapping paper.

According to another embodiment, the smoking article is characterized in that at least a portion of the second wrapper is circumferentially and longitudinally continuous with a constant thickness.

If the thickness of the second wrapper is constant in the circumferential and longitudinal directions, it is advantageous to simultaneously produce a plurality of second wrappers. The tobacco product is preferably applied to the outer and/or inner surface of the second wrapper during the manufacturing process. The final process step is preferably the step of cutting a single second piece of wrapper paper. It is also possible to apply the tobacco product after the cutting process.

According to another embodiment, a smoking article is characterized in that the heating section comprises at least one excipient material portion comprising a tobacco product.

The excipient material part is preferably printed with an ink containing a tobacco product. The heating section comprising a portion of the excipient material preferably allows the tobacco taste to be intensified during a smoking experience. Application of the portion of excipient material coated with the tobacco product to the heating section increases the tobacco taste of the smoking article preferably containing the tobacco product in the second roll. It is also possible to make a difference between the tobacco taste of the tobacco product applied to the second wrapper and the tobacco taste of the tobacco product applied to the excipient material portion. Preferably the tobacco product-containing ink intended for printing on the excipient material part is visible or invisible. Also preferably, the tobacco product-containing ink contains the same components as the ink intended for printing on secondary paper.

It is also possible to spray the tobacco product onto at least one of the surfaces of the excipient material part. Preferably, the thickness of the excipient material portion is constant. In this case, the entire surface is coated with tobacco product-containing ink. The thickness of the excipient material portion may not be constant. To at least one surface of the excipient material part an ink comprising a tobacco product is preferably applied to at least one compartment. The coated and uncoated sections preferably form a pattern.

According to another embodiment, the smoking article is characterized in that the cooling compartment also comprises a tobacco product.

Application of tobacco product to the cooling compartment can further increase the intense tobacco taste. Preferably, the tobacco product is applied to the cooling compartment, the second wrapper and/or excipient material portion of the heating compartment. By combining various application methods, flexibility can be achieved in the manufacture of smoking articles. The smoking article may contain tobacco product in a second wrapper in a heating compartment, an excipient material portion in the heating compartment, and a cooling compartment. Another smoking article includes tobacco product-containing excipient material portions only in the heating section. By combining different tobacco products on different surfaces it is possible to create different tobacco flavors. It is also possible to apply the tobacco product to the excipient material part and to the cooling section. Tobacco products can be combined in a variety of other acceptable ways.

According to another embodiment, the smoking article comprises an excipient material, preferably comprising paper, more preferably a heat-resistant polymer, most preferably a cellulosic material, wherein the second wrapper wraps in a circumferential direction. It is characterized in that it is surrounded by the first paper.

The length of the string is preferably less than or equal to the longitudinal length of the heating section. It is possible that the part of the excipient material is in the form of a thin tube. Preferably the center of the circumference of the tube is an empty space.

The excipient material portion is preferably incorporated into standard manufacturing processes for smoking articles. When more than one material part is used in a smoking article, the tobacco taste is preferably fine-tuned by using different types of tobacco products in individual excipient material parts.

The manner in which the tobacco product is applied to at least one surface of the excipient material portion provides more possibilities for adjusting the tobacco taste. Depending on the number of excipient material parts added to the smoking article, the taste of the tobacco increases or decreases. In addition, there is a method of wetting one or both surfaces of the excipient material part with a tobacco product, and in this case, if one surface of the excipient material part is wetted, a milder tobacco taste is obtained.

According to another embodiment, the smoking article is characterized in that the excipient material portion is perforated to improve the longitudinal flow path.

Portions of excipient material inserted into the heating section can affect the flow path of the smoke in the smoking article. To solve this problem, the excipient material part is preferably perforated. It is possible that the perforations are circular or square. The perforations preferably range in size from 35 μm to 1000 μm, also preferably from 900 μm to 10 mm. Preferably the perforations are formed before or after the coating process of the excipient material part. Perforations may also be formed during the printing process.

According to another embodiment, the smoking article is characterized in that the portion of excipient material is longitudinally disposed or circumferentially rolled in the heating section.

It is possible for the excipient material parts to be positioned in a variety of ways within the heating section of the smoking article. When the excipient material portion is positioned longitudinally, the excipient material portion runs from the distal end to the buccal end. In another embodiment, the excipient material portion is preferably arranged perpendicular to the longitudinal direction. In this case it is important that the part of the excipient material is perforated to improve the flow path. It is also possible for the excipient material portion to be placed in the heating section and rolled in the circumferential direction. Preferably, the rolled portion of excipient material is centered near the distal end region of the heating section. It is also possible for the rolled excipient material portion to be centered near the mouth end region of the heating section.

According to another embodiment, a smoking article characterized in that the excipient material portion is wetted with the tobacco product.

When the portion of the excipient material comprising the textile material is used in a smoking article, the loose fibers are wetted with the tobacco product-containing liquid and incorporated into the heated section of the smoking article. The soaked tobacco product is absorbed into the structure, preferably via capillary action. For effective wetting with the tobacco product-containing liquid, bath immersion is preferably used in the manufacturing process.

The above object of the present invention is also achieved by a method for manufacturing a smoking article having a cylindrical shape extending in the circumferential and longitudinal directions and having a distal end and a mouth end. at least one heating section comprising tobacco and/or reconstituted tobacco binder (RTB) along the longitudinal direction from the distal end to the mouth end, at least one heating section comprising a cylindrical cooling section material with a flow path from the distal end to the mouth end One cooling section, and a filter section are arranged.

A method of manufacturing a smoking article characterized by coating a second roll sheet with a tobacco product comprising tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles prior to placing a heating section into the smoking article. to be

It is possible to use a second wrapper coated with tobacco product in the same operation line. This means that the coating step is performed during standard manufacturing processes. Preferably, the second paper is coated on the outer surface as a final manufacturing step in the manufacturing process. This final step preferably results in the application of the ink containing the tobacco product to the smoking article. This step is advantageous for manufacturing because standard manufacturing processes are preferably maintained and only final steps added.

It is also possible to wind the coated excipient material used to manufacture the second wrapper around a spool or bobbin and store it. In this case, the coated excipient material is separately processed (preferably, cut into appropriate sizes) and then supplied to the RTB molding process.

The above object of the present invention is also achieved by a method for manufacturing a smoking article characterized in that the tobacco product is applied by spraying or printing techniques to the second wrapper of the heating section.

In this manufacturing step, the tobacco product is mixed with an excipient liquid, preferably water, propylene glycol or glycerin, to suit the printing or spraying device. The specific formulation depends on the printing or spraying technique used in the manufacturing process. The printing process is preferably carried out by using a conventional printing machine to print on a continuous material supplied through the printing machine. Preferably, the printing machine includes a printing roller coated with ink. The printing roller forms a pattern as it rolls over the continuous material. It is also possible to use a screen printing machine or an inkjet printing machine.

The above object of the present invention is also achieved by a method for manufacturing a smoking article characterized in that the tobacco product is applied to a second paper bag through a separate processing step.

The process of applying, preferably printing or spraying, the excipient material part of the smoking article and/or the second wrapper is a separate processing step. It is known that these separate processing steps are performed on different lines of work. This means that the step of coating the excipient material and/or the second roll paper of the smoking article is carried out prior to the standard manufacturing process of the smoking article. This avoids having to adjust the production machine to the coating step. Smoking articles containing a tobacco product in the second wrapper paper and/or excipient material part can thus be produced with known production machines.

Further examples of patterns 17 that can be deposited are shown. In FIG. 4a the black lines represent the tobacco product 11 and the white background represents the surfaces 13, 14, 20 and 21. The pattern may include hexagonal shapes, concentric squares, rectangles or circles, zigzag or squiggly lines, and/or parallel straight or curved lines. As an alternative to or in addition to the different thickness 18 of the second wrapper 6 or excipient material portion 7 shown in FIG. 3 a, the pattern 17 may be increased or decreased in density to form a surface 13, 14, 20, 21 It is also possible to increase or decrease the amount of tobacco product deposited per unit area of ). Figure 4a shows various patterns 17, with each pattern represented at a different density. In particular, the density of these patterns 17 increases from left to right in FIG. 4A. The higher the pattern density, the greater the amount of tobacco product 11 per unit area of surface 13 , 14 , 20 , 21 . Accordingly, the lower the pattern density, the lower the amount of tobacco product 11 per unit area of surface 13, 14, 20, 21.

4b shows three different embodiments of possible additional patterns 17 . The uppermost pattern 17 includes a checkerboard pattern. In FIG. 4B, the pattern 17 at the bottom also includes a checkerboard pattern. In the pattern 17 shown in the middle of FIG. 4B, squares or pixels are irregularly distributed. Here too, black represents the compartment 15 coated with the tobacco product 11 and white represents the uncoated compartment 16 . For all three patterns 17 shown in FIG. 4B , the color density 29 of the tobacco product 11 per unit area of surface 13 , 14 , 20 , 21 decreases from left to right. In contrast to FIG. 4a where patterns 17 show a distinct grid-like density from left to right, patterns 17 in FIG. 4b show tobacco product per unit area of surface 13, 14, 20, 21 ( 11) shows a gradual change in density. This is done by gradually reducing the size of the squares coated with tobacco product 11 in a checkerboard pattern, or by reducing the size of pixels coated with tobacco product 11 if the squares coated with tobacco product 11 are irregularly arranged. This is done by gradually reducing With these patterns 17, it is not only feasible to lower or increase the density of the pattern 17 along the flow path 10, but also to repeat the cycle of lowering and then raising the density as often as desired to ensure that the surface 13, 14, 20 , 21), it is also possible to construct an alternating density of tobacco products 11. In this way, the amount of tobacco product 11 deposited per unit area of the surface 13 , 14 , 20 , 21 can be adjusted very precisely to the desired tobacco fortification of the heating zone 1 .

5 shows a flow diagram of a method for manufacturing a smoking article 8. The method may begin with step 100 of coating the second wrapper 6 with a tobacco product. In particular, the outer surface 13 and/or the inner surface 14 of the second wrapper 6 is coated with the tobacco product 11 . This can be done with a jetting or printing (101) technique. In the case of the spraying 101 technique, the tobacco product 11 is applied to the outer surface 13 and/or the inner surface 14 of the second wrapper 6 using a spray nozzle. If it is desired to place the tobacco product 11 on the surfaces 13 and/or 14 within the pattern 17, a mask may be placed between the spray nozzle and said surface 13 and/or 14 or the desired pattern 17 By moving the spray nozzle relative to the surface 13 and/or 14 along the pattern 17 is obtained. If it is desired to coat (100) the tobacco product (11) on the surface (13 and/or 14) by the printing (101) technique, the tobacco product (11) is preferably printed on the second paper (6) using a printing roller. It is applied to the surface (13 and / or 14) of. The printing roller may include concave surface portions. Preferably, these concave surface portions form the negative portions of the pattern 17 , and the tobacco product 11 is advantageously coated 100 on the surface 13 and/or 14 .

The step 100 of coating the excipient material part 7 with the tobacco product 11 is identical to the step 100 of coating the second wrapper 6 of the heating compartment 1 . It is possible that the processing step comprising the step 102 of applying the tobacco product 11 to the second wrapper 6 and/or the excipient material part 7 is a separate processing step. Preferably, the application step 102 is performed prior to standard manufacturing processes for smoking articles 8. It is also possible to carry out the application step 102 in the manufacturing process after the standard manufacturing process of the smoking article 8 .
