Description

The present invention relates to smoking devices in the field of heated non-combustible products with a heated part, including tobacco products for an intensive smoking experience with full tobacco taste. The invention also relates to a method for manufacturing the described smoking article.

There are various types of heated non-combustible products on the market. Most of these use battery-powered heating systems to heat the tobacco within the heating section. This heats the tobacco at a lower temperature than traditional cigarettes. Once the cigarette begins to heat up, the aerosol containing nicotine and other chemicals can be inhaled by the user.

The lower temperatures during the smoking experience result in an incomplete taste compared to traditional cigarettes. As a result, users often criticize the imperfect taste of heated non-combustion products. This problem is often masked by adding flavors to tobacco, and users often do not want to taste any other flavor other than tobacco.

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

Furthermore, China Patent Application No. 105002785A discloses a liner paper for cigarettes, in which the surface of the base paper is coated with a coating liquid containing tobacco extract as the main solute. This document also discloses packaging materials for cigarettes to prevent moisture, mold and aroma loss.

It would be desirable to provide a smoking device that allows a user to conveniently and effectively incorporate a desired tobacco flavor into the aerosol prior to inhalation. Such a smoking device would be particularly desirable if it could be adapted to allow the user to select from a variety of different tobacco flavors and flavor intensities. Preferably, such smoking devices can be manufactured on a common processing machine.

It is therefore an object of the present invention to provide a heated, non-combustible smoking device that is full of tobacco flavor, and a method for manufacturing the described smoking device. The smoking experience is therefore comparable to traditional cigarettes.

The aforementioned problems are solved by a smoking device with a distal end and a mouth end. The smoking device has a cylindrical shape and extends in the circumferential and longitudinal directions. Disposed longitudinally from the distal end to the mouth end are 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. , thereby creating a flow path from the distal end to the oral end. The heated segment, the cooling segment, and the filter segment are at least partially enclosed by a first wrapper, and the heated segment includes at least one second wrapper. The smoking article is characterized in that the second wrapper is coated with a tobacco product comprising tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco particles.

Applying a tobacco product containing tobacco particles to the second wrapper of the heated section enhances the tobacco taste experience for the customer. 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 enhancement of tobacco taste by adding tobacco product can be regulated by the amount of tobacco product.

Tobacco particles with such a small average particle size provide a high surface area that can be contacted by passing aerosols. This allows transport of molecules from the particles into the aerosol stream. It was found that a particle size of ≦30 μm can carry multiple flavor molecules, which contributes to the full tobacco flavor. Particle size can cause larger or smaller molecules to move from the internal volume of the particles to their faces, where they can pass into the aerosol stream.

In the context of the present invention, the term "tobacco product" also refers to flavor substances comprising tobacco particles with an average particle size (sD50 laser diffraction) of ≦30 μm.

Nicotine can also pass from tobacco particles into the aerosol in a similar manner. The term "flavor molecule" also includes nicotine, since nicotine has a flavor and is usually a component of tobacco.

This property of the particles can also be explained by the rapid heating of the small particles after contact with the hot aerosol stream due to the initiation of movement of flavor molecules within the tobacco particles. Additionally, flavor molecules can arrive at the particle surface and, regardless of their location within the particle, flavor molecules can quickly pass from the particle surface into the aerosol stream.

Preferably, the average size (sD50 laser diffraction) of the tobacco particles is ≧1 μm, preferably ≧2.5 μm, more preferably ≧5 μm, most preferably ≧8 μm. It has been found that grinding tobacco particles to smaller particle sizes can impact flavor. It is believed that some of the tobacco flavor molecules degrade due to high shear energy. Additionally, some flavor molecules can escape from very small tobacco particles during the milling process or during the laser treatment process. This should deplete these flavor molecules within the tobacco particles and result in a different flavor composition for full tobacco flavor.

It has been found advantageous to reduce the viscosity of the grinding composition in order to avoid flavor molecules decomposing during the grinding process. This could be achieved by adding a solvent to the composition. Such a solvent (or "dispersion medium") is preferably selected from the group comprising 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 the desired value without significantly changing the flavor.

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

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

According to another embodiment, the smoking device features a tobacco product disposed on the inner and/or outer surface of the second wrapper.

The tobacco product is mixed with a carrier liquid, preferably water, propylene glycol or glycerin, to make it suitable for printing devices. The particular formulation will depend on the printing technology used. The ink preferably contains ground tobacco in an amount of 1 to 50% by weight, with greater than 50% by weight also preferred. With such an amount of ground tobacco in the mixture, sufficient color intensity is ensured. The viscosity of the ink preferably comprises 30-60 dPas, preferably 50-350 dPas, and the viscosity is measured at 25° C. with a drop-stick viscometer.

The inks preferably include solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter and/or fluorescent agents. If fluorescent agents are used, all fluorescent agents are safe for use in food.

It is advantageous if the second wrapper of the smoking device is blank when applying the tobacco product onto the inner surface of the second wrapper. In this case, the tobacco product is invisible to the customer and the tobacco taste is preferably improved. The inner surface of the second wrapper can be at least partially coated with a tobacco product. Preferably, the tobacco product is sprayed onto the inner surface of the second wrapper. It is also envisaged that a tobacco product is printed on the inner surface of the second wrapper. Preferably, the ink for the printing device includes a tobacco product and a transparent substance.

Applying the tobacco product on the outer surface of the second wrapper is advantageous if the second wrapper of the smoking article is preferably to be decorated. In this case, the tobacco product is visible to the customer and the tobacco taste is preferably further enhanced.

Preferably, the tobacco product is provided with or without a coloring substance, as appropriate. Preferably, the tobacco product applied onto the surface is sensed when touched. More preferably, the side of the second wrapper includes text written as Braille in ink containing a tobacco product.

According to another embodiment, the smoking device is characterized in that the second wrapper comprises at least one uncovered part, preferably a plurality of uncovered parts, the covered parts and the uncovered parts forming a pattern. do.

Generally, a pattern refers to a visible surface view or surface structure. Preferably, the pattern includes minimal repetition (period) of covered and uncovered parts and symmetry. The period of coated and uncoated portions preferably differs depending on the desired enhancement of tobacco taste. Preferably, the tobacco product is applied onto the second wrapper of the smoking device to provide a coating. Preferably, a tobacco product containing visible ink is applied onto the second wrapper covering.

It is envisioned that the distance between the covered portion and the uncovered portion is variable. If a strong tobacco taste is desired, the distance between the coated and uncoated parts is preferably in the order of the size of the at least one coated part. It is also possible that the distance between the covered part and the uncovered part is in order of the size of at least one part of the covered part. If a weak tobacco taste is desired, the distance between the coated and uncoated parts is preferably in the order of the size of the at least two coated parts. The distance between the coated and uncoated parts can also be in the order of magnitude of up to three coated parts, more preferably four or more coated parts.

It is also possible that the printing thickness of the coating is constant. In this case, the pattern preferably extends constantly in the channel direction and in the circumferential direction. The printing thickness of the coating is assumed to be variable. In this case, the pattern preferably extends along the longitudinal direction from the finely printed covering to the strongly printed covering. Preferably, the thickness of the second wrapper on which the tobacco product is printed is variable. The pattern on the outer and/or inner surface of the second wrapper is preferably ribbed with coated and uncoated parts. The pattern on the outer and/or inner surface of the second wrapper is preferably evident to the touch.

In order to improve hiding power, color intensity and the color itself, the inks preferably contain dyes, resins and/or particulate matter.

The pattern on the outer and/or inner surface of the second wrapper includes a circumferential ring applied as a line. The lines are preferably adapted to enhance the desired tobacco flavor. Preferably, the wire has a thickness of 2 mm, with a thickness of 3 mm also preferred, in order to improve the desired strong tobacco. It is envisioned that the pattern includes two lines, three lines or multiple lines. The circumferential ring is preferably applied as a single closed ring or as a spiral with a starting point at the distal end and an ending point at the oral end.

It is also possible that the distance between the longitudinally extending circumferential rings is indeterminate. The pattern on the outer and/or inner surface of the second wrapper preferably begins as weak, thin lines at the distal end and becomes thicker and stronger towards the oral end. It is assumed that the line has a constant thickness. The circumferential ring on the outer and/or inner surface of the second wrapper preferably has a distance of at least 3 mm at the distal end. Due to the longitudinal extension, the distance between the circumferential rings preferably decreases by 0.5 mm for every 1 mm of advancement.

The circumferential ring included in the pattern preferably includes curves, geometric figures or letters. It is also envisioned that the pattern includes identifying features. The identifying feature is preferably a logo, a picture or a notice.

The color intensity of the ink is preferably adapted by selection of tobacco type and density. The more concentrated the ink in a tobacco product, the darker the color of the ink. By using darker types of tobacco, preferably darker ink colors are obtained. Such darker tobacco types are preferably barre tobacco, dark fire-cured tobacco and dark air-cured tobacco. For these darker tobacco types, it is preferred that the ink color be darker and also provide a higher contrast with the lighter colored wrappers.

According to another embodiment, the smoking device is characterized in that the second wrapper has a consistent thickness that extends at least partially in the longitudinal and circumferential directions.

The consistent longitudinal and circumferential thickness of the second wrapper advantageously allows a plurality of second wrapper pieces to be produced simultaneously. The tobacco product is preferably applied onto the outer and/or inner surface of the second wrapper during the manufacturing process. The final processing step is preferably cutting into single second wrapper pieces. It is also envisaged that the tobacco product will be applied after the cutting process.

According to another embodiment, the smoking article is characterized in that the heated segment comprises at least one portion of carrier material comprising a tobacco product.

The carrier material portion is preferably printed with an ink containing a tobacco product. The heated segment comprising the carrier material portion is preferably capable of intensifying the tobacco taste during the smoking experience. By applying a portion of carrier material coated with a tobacco product to the heated segment, the tobacco flavor of the smoking device, preferably comprising a second wrapper containing a tobacco product, is increased. It is also envisioned that the tobacco taste of the tobacco product applied onto the second wrapper will be different from the tobacco taste of the tobacco product applied onto the carrier material portion. Preferably, the ink containing the tobacco product used to print onto the carrier material is visible or invisible. It is also preferred that the ink containing the tobacco product contains the same components as the ink for printing on the second wrapper.

It is also envisaged that the tobacco product is sprayed onto at least one of the sides of the carrier material part. Preferably, the thickness of the carrier material portion is constant. In this case, the entire surface is coated with ink containing tobacco products. It is also possible that the thickness of the carrier material part is indeterminate. The ink containing the tobacco product on at least one side of the carrier material portion is preferably applied to at least one portion. The coated portion and the uncoated portion preferably form a pattern.

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

The strong tobacco taste can be further increased by applying a tobacco product to the cooling zone. Preferably, the tobacco product is applied to the cooling section, the second wrapper of the heating section and/or the carrier material section. Combining different application options allows flexibility in manufacturing smoking devices. The smoking article may contain a tobacco product on a second wrapper of the heating section, on a portion of carrier material within the heating section and within the cooling section. On the other hand, other smoking devices contain only a carrier material portion containing the tobacco product within the heating portion. It is envisaged that the combination of different tobacco products on different surfaces will result in different tobacco tastes. It is also envisaged that the tobacco product is applied onto the carrier material portion and into the cooling segment. It is also possible that other combinations of different containment options for tobacco products exist.

According to another embodiment, the smoking article comprises a second wrapper comprising a carrier material, preferably paper, more preferably a heat resistant polymer, most preferably a cellulosic material, and wherein the second wrapper It is characterized by being surrounded by a trumpet.

Preferably, the second wrapper and carrier material portion of the smoking device include the same carrier material. The carrier material preferably comprises a recycled tobacco (RTB) product. RTB products are known as "sheets" and consist of recycled tobacco stems, stalks, scraps, collected dust, and floor dust, to which adhesives, chemicals, and fillers are added. Preferably, the RTB product adhesive comprises a tobacco product.

It is also envisaged that the carrier material includes paper, high temperature polymers and/or cellulosic materials. Heat-resistant polymers used in smoking devices preferably include polysulfone, polyetherimide or polyphenylsulfone. The heat resistant polymer can also include polyphenylene sulfide, liquid crystal polymer, polyetheretherketone or polyphthalamide.

Preferably, at least one portion of carrier material is formed as a strip. The width of the strip is preferably less than the circumferential diameter of the rod of the smoking article. The length of the strip is preferably less than or equal to the longitudinal length of the heating section of the smoking article. In another embodiment, the at least one portion of carrier material is formed as a string, preferably as a twisted rope. The diameter of the string is preferably less than the circumferential diameter of the rod of the smoking device. The length of the string is preferably equal to or less than the length of the heating section in the longitudinal direction. It is envisaged that the carrier material part is formed as a thin tube. The tube is preferably hollow at its circumferential center.

The carrier material part is preferably integrated into the standard manufacturing process of the smoking device. When there is more than one part of the material used in the smoking device, the tobacco taste is preferably fine-tuned by using different types of tobacco products on the individual parts of the carrier material.

Applying a tobacco product to at least one side of the carrier material portion provides a further possibility of adding a tobacco flavor. Depending on the number of parts of carrier material added to the smoking device, the tobacco flavor will be increased or decreased. The option of moistening the carrier material on one or both sides with a tobacco product also exists; moistening one side of the carrier material results in a lighter tobacco taste.

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

The smoke flow path within the smoking device can be influenced due to the portion of carrier material inserted within the heating section. To solve this problem, the carrier material part is preferably perforated. It is envisaged that the perforations are circular or square shaped. The perforations preferably have a size in the range 35 μm to 1000 μm, with 900 μm to 10 mm also preferred. Preferably, the perforations are made before and after the step of coating the carrier material part. Perforations can also be created during the printing process.

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

It is envisaged that the carrier material portion may be positioned in different ways within the heating section of the smoking article. When the carrier material portion is longitudinally positioned, it extends from the distal end to the oral end. In another embodiment, the carrier material portions are preferably arranged perpendicular to the longitudinal direction. In this case it is important that the carrier material part is perforated to improve the flow path. It is also envisaged that the carrier material portion is circumferentially wound and positioned within the heated segment. Preferably, the rolled portion of carrier material is centrally located close to the distal end region of the heated portion. It is also possible for the rolled part of carrier material to be centrally located close to the mouth end area of the part to be heated.

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

When using a carrier material part comprising a woven fabric in a smoking article, the loose fibers are immersed in a liquid containing the tobacco product and integrated into the heated part of the smoking article. The soaked tobacco product is preferably wicked by a structure that allows capillarity to pass through. Bath immersion is preferably used in the manufacturing process to effectively aspirate the liquid containing the tobacco product.

The object is also achieved by a method for manufacturing a smoking device with a distal end and a mouth end having a cylindrical shape and extending circumferentially and longitudinally. longitudinally from the distal end to the mouth end, at least one heated segment containing tobacco and/or recycled tobacco binder (RTB), a cylindrical shaped cold material with a flow path from the distal end to the mouth end; At least one cooling segment including a filter segment is disposed. The heated segment, the cooling segment, and the filter segment are at least partially enclosed by a first wrapper, and the heated segment includes at least one second wrapper. A method for manufacturing a smoking article comprises tobacco particles having an average particle size of 30 μm and a dispersion medium for dispersing the tobacco product prior to placing a heated segment within the smoking article. It is characterized by covering the trumpet.

A second wrapper coated with tobacco product is envisaged for use on the line. This means that the coating step occurs during the standard manufacturing process. Preferably, the second wrapper is coated onto the outer surface during the manufacturing process as the last manufacturing step. Due to the last step, the ink containing the tobacco product is preferably applied onto the smoking device. This step is advantageous for manufacturing because standard manufacturing processes are preferably maintained and only the last step is added.

It is also envisaged that the coated carrier material used to manufacture the second wrapper is stored on a spool or bobbin. In this case, the coated carrier material is processed, preferably cut to size and fed separately to the RTB forming process.

The object is also achieved by a method for manufacturing a smoking article, characterized in that the tobacco product is applied by spraying or printing to the second wrapper of the heated segment.

For this manufacturing step, the tobacco product is mixed with a carrier liquid, preferably water, propylene glycol or glycerin, in order to make it compatible with the printing or spraying device. The particular formulation will depend on the printing or spraying technique used in the manufacturing process. The printing process is preferably performed on a conventional printing press to print on a continuous material that is fed through the printing press. Preferably, the printing press includes a printing roller coated with ink. The printing roller rotates over a continuous surface of material to form a pattern. It is also envisaged to use screen printers or inkjet printers.

The object is also achieved by a method for manufacturing a smoking article, characterized in that the tobacco product is applied to the second wrapper in a separate processing step.

The steps of applying, preferably printing or spraying, the carrier material part and/or the second wrapper of the smoking article are separate processing steps. Such a separate processing step is known as off-line, meaning that the coating of the carrier material and/or the second wrapper of the smoking article takes place before the standard manufacturing process of the smoking article. In this way there is no need to adapt the manufacturing machine for the coating step. A smoking article comprising a second wrapper and/or a carrier material portion containing a tobacco product can thus be produced on known production machines.

Further advantages, objects and features of the invention will be described, by way of example only, in the following description with reference to the accompanying drawings, in which: FIG.

This results in more tobacco products 11 per unit area of the surfaces 13, 14, 20, 21 in order to increase the density of the pattern. This therefore results in a lower amount of tobacco product 11 per unit area of the surfaces 13, 14, 20, 21 due to the lower density of the pattern.

FIG. 4b shows three different embodiments of 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 pattern 17 shown in the middle of Figure 4b comprises a random distribution of squares or pixels. Again, the black color represents the coated portion 15 of the tobacco product 11 and the white color represents the uncoated portion 16. All three patterns 17 shown in Figure 4b include tobacco products 11 of decreasing color density 29 per unit area of surfaces 13, 14, 20, 21 from left to right. In contrast to Figure 4a, where pattern 17 from left to right shows distinct steps of concentration, pattern 17 in Figure 4b shows a gradually varying concentration of tobacco product per unit area of surfaces 13, 14, 20, 21. 11 is shown. This can be done by gradually reducing the size of the squares coated with the tobacco product 11 in a checkerboard pattern or in the case of a chaotic arrangement of the squares coated with the tobacco product 11. This is done by gradually reducing the density of the pixels. In these patterns 17, along the flow path 10, it is envisaged not only to notice an increase or decrease in the concentration of the pattern 17, but also to reduce the concentration, then increase the concentration and repeat this cycle with the desired frequency. It is thus also envisaged to produce alternating concentrations of tobacco product 11 on surfaces 13, 14, 20, 21. In this way, the amount of tobacco product 11 deposited per unit area of surfaces 13, 14, 20, 21 can be adapted very precisely to the desired tobacco intensification of heated segment 1.

FIG. 5 shows a flowchart of a method for manufacturing smoking article 8. The method may begin by coating 100 a second wrapper 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 wrapper 6. This can be done by spraying or by printing 101. For spraying 101, the tobacco product 11 is applied to the inner surface 14 and/or outer surface 13 of the second wrapper 6 with a spray nozzle. When the tobacco product 11 is placed 100 on the surface 13 and/or 14 in a pattern 17, the pattern 17 is formed by placing a cover between the spray nozzle and the surface 13 and/or 14, or by placing a cover between the spray nozzle and the surface 13 and/or 14. This is accomplished by moving the spray nozzle following the desired pattern 17 relative to 14. If the tobacco product 11 is coated 100 on the side 13 and/or 14 by printing 101, the tobacco product 11 is applied onto the side 13 and/or 14 of the second wrapper 6, preferably with a printing roller. The printing roller may include a recessed surface. Preferably, the recessed surfaces form the negative of the pattern 17 in which it is desired that the tobacco product 11 be coated 100 on the surfaces 13 and/or 14.

The method for coating 100 the carrier material part 7 with the tobacco product 11 is the same as the method for coating 100 the second wrapper 6 of the heated part 1 . It is envisaged that the processing step comprising applying 102 the tobacco product 11 to the second wrapper 6 and/or the carrier material portion 7 is a separate processing step. Preferably, the applying step 102 is performed before the standard manufacturing process of the smoking device 8. It is also assumed that the applying step 102 in the manufacturing process is performed after the standard manufacturing process of the smoking device 8.
