Description

Technical Field

[0001] The present invention relates to a smoking device in the field of heated non-combustion products provided with a heating part, including a tobacco product for a concentrated smoking experience with a sufficient tobacco flavor. The present invention also relates to a method for manufacturing the described smoking device.

Background Art

[0002] There are various types of heated non-combustion products in the market. Most of these use a battery-powered heating system for heating the tobacco within the heating part. This heats the tobacco leaves at a lower temperature than conventional cigarettes. When the tobacco starts to heat up, an aerosol containing nicotine and other chemicals can be inhaled by the user.

[0003] Due to being at a low temperature during the smoking experience, the taste is less complete compared to conventional cigarettes. As a result, users often criticize the incomplete taste of heated non-combustion products. This problem is often covered by adding flavor to the tobacco, and users often do not want to taste any other flavor other than tobacco.

[0004] For example, US Patent Application Publication No. 20040020504A1 discloses a combustible treated paper having a sidestream cigarette including a conventional tobacco rod and a sidestream treatment composition. The paper is coated with the treatment composition, and the treatment composition is sprayed onto the paper.

[0005] Furthermore, Chinese Patent Application Publication No. 105002785A discloses a lining paper for cigarettes, and the surface of the base paper is coated with a coating liquid containing a tobacco extract as the main solute. This document also discloses a packaging material for cigarettes to prevent moisture, mold, and aroma loss.

[0006] It is desirable to provide a smoking device that allows the user to conveniently and effectively incorporate a desired tobacco flavor into the aerosol before inhalation. Such a smoking device is particularly desirable if it can be adapted to allow the user to select from a variety of different tobacco flavors and flavor intensities. Preferably, such a smoking device can be manufactured using a common processing machine. [Overview of the project] [Problems that the invention aims to solve]

[0007] Therefore, the object of the present invention is to provide a heated, non-combustion smoking device that is full of tobacco flavor, and a method for manufacturing the smoking device described. The smoking experience is therefore comparable to that of conventional cigarettes. [Means for solving the problem]

[0008] The aforementioned problem is solved by a smoking device having a distal end and a mouth end. The smoking device has a cylindrical shape and extends in the circumferential and longitudinal directions. Along the longitudinal direction from the distal end to the mouth end, at least one heated segment containing tobacco and / or recycled tobacco binder (RTB), at least one cooling segment containing a cylindrical coolant, and a filter segment are arranged, thereby creating a flow path from the distal end to the mouth end. At least a portion of the heated segment, the cooling segment, and the filter segment are enclosed by a first trumpet, and the heated segment includes at least one second trumpet. The smoking device is characterized in that the second trumpet is covered with a tobacco product containing tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles.

[0009] The customer's tobacco flavor experience is enhanced by applying a tobacco product containing tobacco particles to the second trumpet of the heating section. When the second trumpet is heated, the tobacco particles are inhaled together with the actual tobacco aerosol. This further enhances the tobacco flavor. Preferably, the enhancement of the tobacco flavor by adding tobacco product can be adjusted by the amount of tobacco product.

[0010] Tobacco particles with such small average particle sizes provide a high surface area that passing aerosols can come into contact with. This allows molecules to be carried from the particles into the aerosol stream. Particle sizes of ≤30 μm have been found to be able to carry multiple flavor molecules, which contributes to a sufficient tobacco flavor. Particle size can move larger or smaller molecules from the internal volume of the particles to their surfaces, and these molecules can then pass from the surface into the aerosol stream.

[0011] In the context of this invention, the term "tobacco product" also refers to flavoring substances containing tobacco particles having an average particle size of ≤30 μm (sD50 laser diffraction).

[0012] Nicotine can also pass from tobacco particles into aerosols in a similar manner. Since nicotine has flavor and is a component of tobacco, the term "flavor molecule" also includes nicotine.

[0013] This property of the particles can also be explained by the rapid heating of the small particles after contact with a high-temperature aerosol stream, which is due to the initiation of flavor molecule migration within the tobacco particles. Furthermore, flavor molecules can reach the particle surface and, regardless of their position within the particle, can quickly pass from the particle surface into the aerosol stream.

[0014] Preferably, the average size of the tobacco particles (sD50 laser diffraction) is ≥1 μm, preferably ≥2.5 μm, more preferably ≥5 μm, and most preferably ≥8 μm. It has been found that grinding the tobacco particles to a smaller particle size can affect the flavor. It is thought that some of the flavor molecules of the tobacco leaves decompose due to the high shear energy. Furthermore, some flavor molecules may be released from the very small tobacco particles during the grinding or laser processing steps. This should deplete these flavor molecules within the tobacco particles, resulting in a different flavor composition for a sufficient tobacco flavor.

[0015] It has been found that reducing the viscosity of the pulverized composition is advantageous in order to avoid the decomposition of flavor molecules during the pulverization process. This could be achieved by adding a solvent to the composition. Such a solvent (or "dispersion medium") is preferably selected from the group including water, monohydric alcohols, polyhydric alcohols, sugar alcohols, sugars, and polyhydric alcohol esters. By using such a dispersion medium, the average particle size of the tobacco can be adjusted to a desired value without significantly altering the flavor.

[0016] In addition to tobacco particles with an average particle size of 30 micrometers or less, the tobacco product preferably contains a liquid medium such as alcohol or water, in which the tobacco particles are dispersed.

[0017] In a preferred embodiment, tobacco particles are dispersed in a liquid medium having a temperature of ≤30°C, preferably ≤20°C, more preferably ≤15°C, and most preferably ≤10°C, to prevent the decomposition and / or dissipation of tobacco flavor. Preferably, the dispersion liquid medium has a temperature of ≥-20°C, preferably ≥-10°C, more preferably ≥-5°C, and most preferably ≥0°C, to facilitate its handling. Low-temperature dispersions having temperatures within the above range have also been shown to prevent nicotine decomposition.

[0018] According to another embodiment, the smoking apparatus is characterized by a tobacco product placed on the inner and / or outer surface of a second trumpet.

[0019] Tobacco products are mixed with a carrier liquid, preferably water, propylene glycol, or glycerin, to make them suitable for printing devices. The specific formulation depends on the printing technology used. The ink preferably contains 1 to 50% by weight of ground tobacco, and more than 50% by weight is also preferred. Such an amount of ground tobacco in the mixture ensures sufficient color intensity. The viscosity of the ink preferably contains 30 to 60 dPas, and 50 to 350 dPas is also preferred, and the viscosity is measured at 25°C with a drop-stick viscometer. Preferably 0.5 g / cm³ 3 ~0.9g / cm 3It contains ink with a density of 0.8 g / cm³. 3 ~1.5g / cm 3 Ink is also preferable. The ink preferably contains a solvent, pigment, dye, resin, lubricant, solvent, surfactant, particulate matter and / or fluorescent agent. If a fluorescent agent is used, all fluorescent agents are safe for use in food.

[0020] When applying the tobacco product to the inner surface of the second trumpet, it is advantageous if the second trumpet of the smoking device is made of plain paper. In this case, the tobacco product is not visible to the customer, and the tobacco flavor is preferably enhanced. The inner surface of the second trumpet can be covered with the tobacco product, at least in part. Preferably, the tobacco product is sprayed onto the inner surface of the second trumpet. It is also conceivable that the tobacco product be printed onto the inner surface of the second trumpet. Preferably, the ink for the printing device contains the tobacco product and a transparent substance.

[0021] Applying a tobacco product to the outer surface of the second trumpet is advantageous when the second trumpet of the smoking instrument is preferably to be decorated. In this case, the tobacco product is visible to the customer, and the tobacco flavor is preferably further enhanced. The outer surface of the second trumpet can be covered with the tobacco product, at least in part. Preferably, the tobacco product is sprayed onto the outer surface of the second trumpet. It is also conceivable that the tobacco product is printed onto the outer surface of the second trumpet. Preferably, the ink for the printing device contains the tobacco product and a coloring agent. It is also conceivable that the tobacco product applied to the outer surface of the second trumpet is invisible. In this case, the ink for the printing device is transparent.

[0022] The tobacco product may also be applied to the inner and outer surfaces of the second flank. The tobacco product may or may not include a coloring agent, as needed. Preferably, the tobacco product applied to the surface is detectable by touch. More preferably, the surface of the second flank includes characters written as Braille with ink containing the tobacco product.

[0023] According to another embodiment, the smoking device is characterized in that the second bellows includes at least one uncovered portion, preferably a plurality of uncovered portions, and the covered and uncovered portions form a pattern.

[0024] Generally, the pattern refers to a visible surface view or surface structure. Preferably, the pattern includes the minimum repetition (period) and symmetry of the covered and uncovered portions. The period of the covered and uncovered portions preferably varies depending on the desired improvement in tobacco flavor. Preferably, the tobacco product is applied onto the second bellows of the smoking device, resulting in the covered portion. Preferably, the tobacco product containing visible ink is applied onto the covered portion of the second bellows.

[0025] The distance between the covered and uncovered portions is assumed to be variable. If a strong tobacco flavor is desired, the distance between the covered and uncovered portions is preferably in the order of the size of at least one covered portion. It is also possible that the distance between the covered and uncovered portions is in the order of the size of at least one part of the covered portion. If a weak tobacco flavor is desired, the distance between the covered and uncovered portions is preferably in the order of the size of at least two covered portions. It is also possible that the distance between the covered and uncovered portions is in the order of the size of up to three covered portions, more preferably four or more covered portions.

[0026] The thickness of the printing of the covered portion can also be constant. In this case, the pattern preferably extends uniformly in the flow direction and circumferential direction. The thickness of the printing of the covered portion is assumed to be variable. In this case, the pattern preferably extends longitudinally from the finely printed covered portion to the strongly printed covered portion. Preferably, the thickness of the second bellows on which the tobacco product is printed is variable. The pattern on the outer surface and / or inner surface of the second bellows is preferably ridged by the covered and uncovered portions. The pattern on the outer surface and / or inner surface of the second bellows is preferably discernible by touch.

[0027] To improve the hiding power, color intensity and the color itself, the ink preferably contains dyes, resins and / or particulate substances. By adding solvents, resins, lubricating oils, solvents and / or surfactants, the rheology of the ink is preferably optimized for the printing process. Such optimization is particularly interesting for adapting the ink to a specific printing press. By adding fluorescent agents, the print is preferably readable under ultraviolet irradiation.

[0028] According to another embodiment, the smoking device includes a circumferential ring in which the pattern extends longitudinally, and the circumferential rings are spaced apart from each other longitudinally.

[0029] Preferably, the distance between the circumferential rings extending longitudinally is constant. The pattern on the outer and / or inner surface of the second bellows includes circumferential rings applied as lines. The lines are preferably adapted to improve the desired tobacco flavor. Preferably, the lines have a thickness of 2 mm and a thickness of 3 mm is also preferred to improve the desired strong tobacco. The pattern is envisioned to include two lines, three lines or multiple lines. The circumferential rings are preferably added as a single closed ring or as a helix with a starting point at the distal end and an end point at the mouth end.

[0030] It is also possible that the distance between the circumferential rings extending longitudinally is variable. The pattern on the outer and / or inner surface of the second bellows preferably starts with a thin and weak line at the distal end and becomes thicker and stronger towards the mouth end. It is envisioned that the lines have a constant thickness. The circumferential rings on the outer and / or inner surface of the second bellows preferably have a distance of at least 3 mm at the distal end. Due to extending longitudinally, the distance between the circumferential rings preferably decreases by 0.5 mm for every 1 mm advancement.

[0031] The circumferential rings included in the pattern preferably include curves, geometric figures or characters. It is also envisioned that the pattern includes distinguishing features. The distinguishing features are preferably a logo, a picture or a cautionary note.

[0032] The color intensity of the ink is preferably adjusted by selecting the type and density of tobacco. The higher the density of the tobacco product's ink, the darker the ink color. By using darker types of tobacco, a darker ink color is preferably obtained. Such darker types of tobacco are preferably burr tobacco, dark-colored charcoal-dried tobacco, and dark-colored air-dried tobacco. With such darker types of tobacco, it is preferable that the ink color becomes darker and the contrast with lighter-colored tumblers is also greater.

[0033] According to another embodiment, the smoking device is characterized in that the second flaps have a consistent thickness that extends at least partially longitudinally and circumferentially.

[0034] The consistent longitudinal and circumferential thickness of the second trumpet is advantageous, as it allows for the simultaneous production of multiple pieces of the second trumpet. The tobacco product is preferably applied to the outer and / or inner surfaces of the second trumpet during the manufacturing process. The final processing step is preferably cutting into single pieces of the second trumpet. The tobacco product may also be applied after the cutting step.

[0035] According to another embodiment, the smoking device is characterized in that the heated segment includes at least one carrier material portion containing a tobacco product.

[0036] The carrier material portion is preferably printed with an ink containing a tobacco product. The heated segment containing the carrier material portion can preferably enhance the tobacco flavor during the smoking experience. Applying the carrier material portion coated with the tobacco product to the heated segment preferably increases the tobacco flavor of a smoking device equipped with a second trumpet containing the tobacco product. It is also conceivable that the tobacco flavor of a tobacco product applied to the second trumpet may differ from the tobacco flavor of a tobacco product applied to the carrier material portion. The ink containing the tobacco product used to print on the carrier material portion is preferably visible or invisible. The ink containing the tobacco product may also preferably contain the same components as the ink used to print on the second trumpet.

[0037] The tobacco product may also be sprayed onto at least one surface of the carrier material. Preferably, the thickness of the carrier material is constant. In this case, the entire surface is covered with ink containing the tobacco product. The thickness of the carrier material can also be variable. Preferably, at least one portion of the ink containing the tobacco product is applied to at least one surface of the carrier material. The covered and uncovered portions preferably form a pattern.

[0038] According to another embodiment, the smoking device is characterized in that the cooling segment also includes a tobacco product.

[0039] Applying a tobacco product to the cooling section can further enhance the strong tobacco flavor. Preferably, the tobacco product is applied to the cooling section, the second trumpet of the heating section, and / or the carrier material section. Combinations of different application options allow for flexibility in the manufacture of smoking devices. A smoking device may contain the tobacco product on the second trumpet of the heating section, within the heating section, and on the carrier material section within the cooling section. On the other hand, another smoking device may contain only a carrier material section containing the tobacco product within the heating section. Different combinations of different tobacco products on different surfaces are expected to result in different tobacco flavors. The tobacco product may also be applied to the carrier material section and within the cooling segment. Other combinations of different accommodation options for the tobacco product are also possible.

[0040] According to another embodiment, the smoking device is characterized in that the second flaps contain a carrier material, preferably paper, more preferably a heat-resistant polymer, and most preferably a cellulose-based material, and the second flaps are surrounded by the first flaps.

[0041] Preferably, the second trumpet and carrier material portion of the smoking device contain the same carrier material. The carrier material preferably contains a re-to-beverage (RTB) product. The RTB product is known as a "sheet," which consists of re-tobacco stems, stalks, scraps, collected dust, and floor dust, to which adhesives, chemicals, and fillers are added. Preferably, the adhesive in the RTB product contains a tobacco product.

[0042] The carrier material may include paper, heat-resistant polymers, and / or cellulosic materials. The heat-resistant polymer used in smoking devices preferably includes polysulfone, polyetherimide, or polyphenylsulfone. The heat-resistant polymer may also include polyphenylene sulfide, liquid crystal polymer, polyetheretherketone, or polyphthalamide.

[0043] According to another embodiment, the smoking device is characterized in that the heated segment includes at least one carrier material portion, preferably as a strip or string, and the tobacco product is applied to at least one side of the carrier material portion.

[0044] Preferably, at least one carrier material portion is formed as a strip. The width of the strip is preferably shorter than the circumferential diameter of the rod of the smoking device. The length of the strip is preferably less than or equal to the longitudinal length of the heating portion of the smoking device. In another embodiment, at least one carrier material portion is formed as a string, preferably as a twisted rope. The diameter of the string is preferably shorter than the circumferential diameter of the rod of the smoking device. The length of the string is preferably less than or equal to the longitudinal length of the heating portion. The carrier material portion is assumed to be formed as a thin tube. The tube is preferably hollow at its circumferential center.

[0045] The carrier material is preferably integrated into the standard manufacturing process of the smoking device. If there are two or more material parts used in the smoking device, the tobacco flavor is preferably fine-tuned by using different types of tobacco products on each carrier material part.

[0046] Applying tobacco product to at least one side of the carrier material portion provides further possibilities for adding tobacco flavor. The tobacco flavor will increase or decrease depending on the number of carrier material portions added to the smoking device. There is also the option of moistening one or both sides of the carrier material portion with tobacco product, and moistening one side of the carrier material portion results in a lighter tobacco flavor.

[0047] According to another embodiment, the smoking device is characterized in that the carrier material portion is perforated to improve the longitudinal flow path.

[0048] The smoke flow path within the smoking device may be affected by the carrier material inserted into the heating element. To solve this problem, the carrier material is preferably perforated. The perforations are expected to be circular or square in shape. The perforations preferably have a size in the range of 35 μm to 1000 μm, and 900 μm to 10 mm is also preferred. Preferably, the perforations are created before or after the coating process of the carrier material. The perforations can also be created during the printing process.

[0049] According to another embodiment, the smoking device is characterized in that the carrier material portion is arranged longitudinally within the heated segment or wound circumferentially.

[0050] The carrier material portion is envisioned to be positioned in different ways within the heating section of the smoking device. When the carrier material portion is positioned longitudinally, the portion extends from the distal end to the mouth end. In another embodiment, the carrier material portion is preferably positioned perpendicular to the longitudinal direction. In this case, it is important that the carrier material portion is perforated to improve the airflow. The carrier material portion is also envisioned to be wound circumferentially and positioned within the heated segment. Preferably, the wound carrier material portion is positioned at the center near the distal end region of the heated section. The wound carrier material portion may also be positioned at the center near the mouth end region of the heated section.

[0051] According to another embodiment, the smoking device is characterized in that the carrier material portion is immersed in a tobacco product.

[0052] When a carrier material containing woven fabric is used in a smoking device, the loosened fibers are immersed in a liquid containing tobacco product and integrated into the heated part of the smoking device. The immersed tobacco product is preferably drawn up by a structure that allows capillary action. To effectively draw up the liquid containing tobacco product, bath immersion is preferably used in the manufacturing process.

[0053] The objective is also achieved by a method for manufacturing a smoking device having a cylindrical shape and extending circumferentially and longitudinally, with a distal end and a mouth end. Along the longitudinal direction from the distal end to the mouth end are arranged at least one heated segment containing tobacco and / or recycled tobacco binder (RTB), at least one cooled segment containing a cylindrical cryogenic material with a flow channel from the distal end to the mouth end, and a filter segment. The heated segment, the cooled segment and the filter segment are at least partially enclosed by a first trumpet, and the heated segment includes at least one second trumpet. The method for manufacturing a smoking device is characterized by covering the second trumpet with a tobacco product, which includes tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco product before placing the heated segment in the smoking device.

[0054] The second flaps, coated with the tobacco product, are intended for use in wires. This means that the coating step occurs during the standard manufacturing process. Preferably, the second flaps are coated on their outer surface during the manufacturing process as the final manufacturing step. As a result of this final step, the ink containing the tobacco product is preferably applied to the smoking device. This step is advantageous for manufacturing because it is preferable for the standard manufacturing process to continue, with only this final step being added.

[0055] The coated carrier material used to manufacture the second trumpet may also be stored on a spool or bobbin. In this case, the coated carrier material is processed, preferably cut to the appropriate size, and separately fed into the RTB forming process.

[0056] The objective can also be achieved by a method for manufacturing a smoking device, characterized in that a tobacco product is applied to a second trumpet of the heated segment by spraying or printing.

[0057] For this manufacturing step, the tobacco product is mixed with a carrier liquid, preferably water, propylene glycol, or glycerin, to make it suitable for a printing or spraying device. The specific formulation depends on the printing or spraying technology used in the manufacturing process. The printing process is performed in a conventional printing press to print on a continuous material fed through the press. Preferably, the printing press includes ink-coated printing rollers. The printing rollers rotate over the surface of the continuous material to form a pattern. The use of screen printing or inkjet printing presses is also conceivable.

[0058] The objective can also be achieved by a method for manufacturing a smoking device, characterized by applying a tobacco product to a second trumpet in a separate processing step.

[0059] The process of coating the carrier material and / or the second flaps of the smoking device, preferably by printing or spraying, is a separate processing step. Such a separate processing step is known as offline, meaning that the coating of the carrier material and / or the second flaps of the smoking device is performed before the standard manufacturing process of the smoking device. In this method, it is not necessary to adapt the manufacturing machine for the coating step. Smoking devices with second flaps and / or carrier material parts containing tobacco products can thus be produced in known production machines.

[0060] Further advantages, purposes, and features of the present invention are described below only by reference to the accompanying drawings. In the drawings, the same components in different embodiments may be indicated by the same reference numerals. [Brief explanation of the drawing]

[Figure 3b] A schematic diagram of the spiral-shaped second trumpet 6 or carrier material section 7 is shown. [Figure 3c] A schematic diagram of the perforated carrier material portion 7 is shown. [Figure 4a] The diagrams show different embodiments of Pattern 17. [Figure 4b] Figures illustrating different embodiments of pattern 17 and color density 29 are shown. [Figure 5] A flowchart of the method for manufacturing smoking device 8 is shown. [Modes for carrying out the invention]

[0062] Figure 1 shows a schematic diagram of a smoking device 8 comprising a heated segment 1, a cooling segment 2, and a filter segment 3. The three described segments 1-3 are connected to one another and at least part of them are enclosed by a first flaps 4, and segments 1-3 are arranged along the longitudinal direction 25 from the distal end 22 to the mouth end 23 of the smoking device 8. Segments 1-3 create a flow path 10, which has an initiation at the distal end 22 and extends along the longitudinal direction 25 to the mouth end 23 throughout the entire smoking device 8. It is possible that further segments or components may be included within the smoking device 8. Thus, it is conceivable that the cooling segment 2, heated segment 1, and filter segment 3 include another flaps. In the shown embodiment, all segments 1-3 are cylindrical in shape. The smoking device 8 is conceivable to have different basic shapes, such as square, hexagonal, or elliptical.

[0063] The heated segment 1 includes a second trumpet 6, a smokeable material, preferably RTB 5, and a carrier material portion 7, at least in part, covered with a tobacco product 11. The second trumpet 6 wraps around the RTB 5 in a circumferential direction 24. The cooling segment 2 includes a coolant 9, which is enclosed within the first trumpet 4 and covered with a tobacco product 11. The cooling segment 2 may include a cooling trumpet (not shown herein). The filter segment 3 includes a filter material 27 and is enclosed within the first trumpet 4. The filter segment 3 is envisioned to include at least one further trumpet enclosing the filter material 27 in a circumferential direction 24.

[0064] The tobacco product 11 contains tobacco particles 12, and the tobacco particles 12 in the cooling segment 2, the tobacco particles 12 on the outer surface of the second trumpet 6, and the tobacco particles on the carrier material portion 7 may be different from each other. Combinations of different tobacco products 11 containing different tobacco particles 12 preferably result in a specific tobacco flavor. The tobacco product 11 on the outer surface 13 of the second trumpet is arranged in such a way that a pattern 17 is formed.

[0065] In the shown embodiment, the first trumpet 4 does not contain the tobacco product 11, but it is certainly conceivable that the tobacco product 11 may be applied to the inner or outer surface of the first trumpet 4. The second trumpet 6 containing the tobacco product 11 may be applied so as to be visible on the heated segment 1, and it is also conceivable that the heated segment 1 may be partially enclosed by the first trumpet 4.

[0066] Figure 1a shows an embodiment of a smoking device 8 with a tobacco product 11 mounted on a second flank 6. The cooling segment 2 does not include the tobacco product 11. The heated segment 1 does not include the carrier material portion 7. Figure 1b shows an embodiment of a smoking device 8 with a tobacco product 11 mounted on a second flank 6 and a cooling segment 2. The heated segment 1 of the smoking device 8 does not include the carrier material portion 7. Figure 1c shows an embodiment of a smoking device 8 with a tobacco product 11 mounted on a carrier material portion 7 and a cooling segment 2. The second flank 6 of the heated segment 1 does not include the tobacco product 11. Figure 1d shows an embodiment of a smoking device 8 with a tobacco product 11 mounted on a second flank 6 and a carrier material portion 7. The cooling segment 2 does not include the tobacco product 11.

[0067] Figure 2 shows a detailed view of the second flaps 6. The second flaps 6 are covered with a tobacco product 11, partly containing tobacco particles 12. The outer surface 13 of the second flaps includes a covered portion 15 and an uncovered portion 16, which form a pattern 17. The pattern 17 on the outer surface 13 of the second flaps is formed as a circumferential ring 26, where the covered portion 15 contains the tobacco product 11 and the uncovered portion 16 contains the RTB surface 28. The circumferential rings 26 are preferably spaced apart from each other by a distance d. The distance d is preferably the same thickness as at least one of the circumferential rings 26. It is assumed that the distance d between the circumferential rings 26 is variable. In this case, the distance d can be narrower or thicker as a single circumferential ring 26. It is also assumed that the distance d is indeterminate. In this case, the distance d widens or narrows between the circumferential rings 26 extending from the distal end 22 to the mouth end 23 (not shown). The inner surface 14 of the second trumpet can also be covered with the tobacco product 11, at least in part.

[0068] The length l of the heated segment 1 is preferably 20 mm when measured along the longitudinal direction 25. The length l of the heated segment 1 may also vary depending on the embodiment of the smoking device 8. The length l of the heated segment 1 is intended to be adapted to the other segment of the smoking device 8. In such a case, the length l of the heated segment 8 can be the same as that of the cooling segment 2 or the filter segment 3.

[0069] Figure 3a shows a schematic diagram of the second trumpet 6 or carrier material section 7 with the roll unfolded. Figure 3b shows a schematic diagram of the spiral second trumpet 6 or carrier material section 7. The second trumpet 6 and carrier material section 7 preferably contain the same carrier material 19 as the base. Preferably, the carrier material 19 contains RTB 5. The tobacco product 11 is applied to the first surface 20 of the carrier material or the outer surface 13 of the second trumpet.

[0070] The tobacco product 11 is preferably applied to portion 15, and the coated portions 15 are spaced apart from each other by a distance d. The coated portions 15 are expected to have varying thicknesses, such that the thickness 18 of the entire second trumpet 6 or the entire carrier material 19 is variable. The thickness 18 of the entire second trumpet 6 or the entire carrier material 19 can also be constant. The inner surface 14 of the second trumpet or the second surface 21 of the carrier material can also be coated with the tobacco product (not shown). Preferably, the thickness t of the coated portion is constant. The thickness t of one coated portion is also preferably in the range of 0.5 to 5 mm. The thickness t of the coated portion is expected to vary depending on the desired improvement of the tobacco flavor. The carrier material portion 7, as shown in Figures 3a and 3b, can be placed within the heated portion 1. The spiral carrier material portion 7 is preferably placed in the center of the heated portion 1. The spiral-shaped carrier material portion 7 may also be positioned in a region other than the center of the heated portion 1, preferably along the longitudinal direction 25, at the distal end 22 or the mouth end 23 of the heated portion 1.

[0071] Figure 3c shows a schematic diagram of the perforated carrier material portion 7. The perforations 30 are randomly arranged on the carrier material portion 7. The perforations 30 are through holes connecting the first surface 20 and the second surface 21. The perforations 30 can be arranged on the surface 20 according to a particular plan. The perforations 30 depicted in Figure 3c are circular. The perforations 30 are assumed to be elliptical, square, or hexagonal in shape. The perforations 30 preferably have a size of 35 μm to 1000 μm, and 900 μm to 10 mm is also preferred. The carrier material portion 7 is preferably arranged perpendicular to the longitudinal direction 25. In this case, the perforations 30 improve the flow path 10 within the heated segment 1.

[0072] Figure 4a shows a further embodiment of pattern 17, where the tobacco product 11 can be deposited on the inner surface 14 and outer surface 13 of the second flaps 6, or on the first surface 20 or second surface 21 of the carrier material portion 7. In Figure 4a, the black lines represent the tobacco product 11, and the white background represents surfaces 13, 14, 20, and 21. The pattern may include hexagonal shapes, concentric squares, rectangles, or circles, zigzag or meandering lines and / or parallel straight or curved lines. As an alternative to or addition to the different thicknesses 18 of the second flaps 6 or carrier material portion 7 depicted in Figure 3a, it is also conceivable that the amount of tobacco product deposited per unit area of ​​surfaces 13, 14, 20, and 21 can be increased or decreased by increasing or decreasing the density of pattern 17. Figure 4a shows each different pattern 17, each shown with a different density. Specifically, the density of pattern 17 increases from left to right in Figure 4a. This results in a larger amount of tobacco product 11 per unit area of ​​surfaces 13, 14, 20, and 21 in order to increase the pattern density. Conversely, this results in a smaller amount of tobacco product 11 per unit area of ​​surfaces 13, 14, 20, and 21 in order to decrease the pattern density.

[0073] Figure 4b shows three different embodiments of the further possible patterns 17. The top pattern 17 includes a checkerboard pattern. The bottom pattern 17 shown in Figure 4b also includes a checkerboard pattern. The middle pattern 17 shown in Figure 4b includes a disordered distribution of squares or pixels. Again, black represents the coated portion 15 of the tobacco product 11, and white represents the uncoated portion 16. All three patterns 17 shown in Figure 4b include tobacco product 11 with decreasing color density 29 per unit area of ​​surfaces 13, 14, 20, and 21 from left to right. In contrast to Figure 4a, where pattern 17 shows clear steps of density from left to right, the patterns 17 in Figure 4b show tobacco product 11 with gradually changing density per unit area of ​​surfaces 13, 14, 20, and 21. This is done by gradually reducing the size of the squares covered with tobacco product 11 in the checkerboard pattern, or, in the case of a disordered arrangement of squares covered with tobacco product 11, by gradually reducing the density of pixels covered with tobacco product 11. In these patterns 17, it is assumed that not only is it possible to recognize the increase or decrease in density of the pattern 17 along the flow path 10, but it is also assumed that alternating densities of tobacco product 11 on surfaces 13, 14, 20, and 21 are generated by decreasing the density, then increasing the density, and repeating this cycle at a desired frequency. In this way, the amount of tobacco product 11 deposited per unit area of ​​surfaces 13, 14, 20, and 21 can be very precisely matched to the desired tobacco enhancement of the heated segment 1.

[0074] Figure 5 shows a flowchart of a method for manufacturing a smoking device 8. The method may begin by coating a second trumpet 100 with a tobacco product 100. Specifically, the tobacco product 11 is coated 100 onto the outer surface 13 and / or inner surface 14 of the second trumpet 6. This can be done by spraying or by printing 101. To spray 101, the tobacco product 11 is applied to the inner surface 14 and / or outer surface 13 of the second trumpet 6 with a spray nozzle. If the tobacco product 11 is arranged 100 on the surface 13 and / or 14 in a pattern 17, the pattern 17 is achieved by placing a cover between the spray nozzle and the surface 13 and / or 14, or by moving the spray nozzle along the desired pattern 17 relative to the surface 13 and / or 14. If the tobacco product 11 is coated 100 onto the surface 13 and / or 14 by printing 101, the tobacco product 11 is preferably applied onto the surface 13 and / or 14 of the second trumpet 6 with a printing roller. The printing roller may include recessed surfaces. Preferably, the recessed surfaces form a negative of a pattern 17 on which the tobacco product 11 is to be coated 100 onto surfaces 13 and / or 14.

[0075] The method for coating the carrier material portion 7 with the tobacco product 11 is the same as the method for coating the second trumpet 6 of the heated portion 1. The processing step comprising applying the tobacco product 11 to the second trumpet 6 and / or the carrier material portion 7 is assumed to be a separate processing step. Preferably, the application step 102 is performed before the standard manufacturing process of the smoking device 8. The application step 102 in the manufacturing process is also assumed to be performed after the standard manufacturing process of the smoking device 8.
