Definitions

  • the invention relates to a smoking article, preferably a heat-not-burn product, comprising an improved taste.
  • the tobacco or tobacco derived smokable material comprised in a tobacco segment is heated with an electrical heat source.
  • the tobacco or tobacco derived smokable material is preferably heated up to 250°C. At these temperatures, the material evaporates a smokable aerosol which may then be inhaled by a user.
  • a heat-not-burn product still comprises taste deficits. It is therefore the objective of the invention to provide a heat-not-burn product with an improved taste.
  • a smoking article comprising a cylindrical shape with a longitudinal axis running through respective base areas of a distal end and a mouth end of the smoking article, wherein the smoking article comprises the following segments, which are arranged subsequently the following order from the distal to the mouth end, and are at least in part wrapped in a circumferential wrapper:
  • the tobacco particles are dispersed in a dispersion medium.
  • the dispersion medium preferably comprises water, monovalent alcohols, polyvalent alcohols, sugar alcohols, sugars and/or polyvalent alcohol esters.
  • the term polyvalent alcohols includes (among others) glycerol and propylene glycol.
  • the dispersion medium together with the tobacco particles forms a liquid or paste-like tobacco product before the tobacco product is arranged in the filter segment.
  • the dispersion medium content in the tobacco product may be reduced due to drying after the tobacco product is arranged in the filter segment.
  • At least one part of the filter segment comprises the shape of a hollow cylinder having an inner lateral area including a through-hole, through which the second flow path is arranged, wherein the second flow path is also parallel to the longitudinal axis, and wherein the inner lateral area is at least in part coated with the tobacco product.
  • the tobacco product on at least a part of the inner lateral area is in direct contact with a second flow path.
  • the tobacco product is preferably coated on only a part of the inner lateral area of the through hole of the at least one part of the filter segment. This means that there are also other parts of the inner lateral area which remain uncoated by the tobacco product.
  • the tobacco product is arranged on at least a part of the inner lateral area in a grated manner and/or in a pattern. In this context grated manner means that the tobacco particle concentration per area unit on the inner lateral area changes along the longitudinal axis. This enables further possibilities to modify and improve the taste profile of the smoking article.
  • At least one part of the filter segment is a filter rod having an inner volume, wherein the tobacco product is arranged in the inner volume of the filter rod
  • the at least one part of the filter segment is a cylindrically shaped filter rod.
  • Such a filter rod is very similar to a normal standard cigarette filter rod.
  • the aerosol flow path is distributed through the whole inner volume of the filter segment.
  • the tobacco product is distributed in the material of the filter segment in a homogeneous way. In this way, the tobacco product is arranged within the material of at least one part of the filter segment.
  • the tobacco product is uniformly distributed within at least one cylindrically shaped section of the filter rod, having the same diameter as the filter rod. With this uniform distribution within the material of the filter rod, the previously described circling of the aerosol around the tobacco particles contained in the tobacco product is possible.
  • the tobacco product is preferably contained only in at least one cylindrically shaped section of the filter rod. This implies that there is another section of the filter rod in which no tobacco product is distributed.
  • this second cylindrically shaped section By arranging this second cylindrically shaped section with the clean visual impression directly at the mouth end and with the second cylindrically shaped section having the same diameter as the filter rod, the consumer can only see the second cylindrically shaped section, whereas the first section comprises the tobacco product and therefore the colored section is hidden from the consumers view.
  • At least one part of the filter segment is a filter rod having an inner volume, wherein at least one thread comprising the tobacco product is arranged in the inner volume of a first cylindrically shaped section of the filter rod, wherein the first cylindrically shaped section has the same diameter as the filter rod.
  • the at least one thread comprising the tobacco product is preferably embedded in the material of the at least one part of the filter segment. It is also conceivable to use more than one thread in the at least one part of the filter segment. By increasing the number of threads comprising the tobacco product, the intensity of the flavor impact of the tobacco product in the aerosol can be adjusted.
  • the thread comprising the tobacco product is preferably suitable for use with the much cooler aerosol of a heat-not-burn product in comparison to a conventional cigarette.
  • the desired flavor is released from the tobacco product at temperatures below the temperature of the aerosol in the second flow path of the filter segment.
  • the flavor of the tobacco product is non-volatile at room temperature. In this way, the flavor is only released during the use of the smoking article and does not diminish during storage of the smoking article before its actual use.
  • a second cylindrically shaped section of the filter rod not comprising the thread and also having the same diameter as the filter rod is arranged between the first section, which comprises the thread, and a mouth end of the smoking article.
  • the tobacco product will color the threads in a dark color.
  • the ends of the threads may be visible at the end of the first section of the filter rod.
  • the objective of the invention is also reached by a method for manufacturing a smoking article, wherein a tobacco segment comprising tobacco or tobacco derived smokable material, a cooling segment comprising a first flow path and a filter segment comprising a second flow path are arranged in the given order subsequently on a longitudinal axis, and are at least in a part wrapped in a circumferential wrapper thereby forming a smoking article having a cylindrical shape with a longitudinal axis running through respective base areas of the smoking article being a distal end, at which a tobacco segment is arranged, and a mouth end, at which the filter segment is arranged, respectively, wherein the first flow path connects the tobacco segment with the filter segment and a second flow path connects the cooling segment with the mouth end.
  • the method is characterized in that before arranging the filter segment next to the cooling segment, a tobacco product comprising tobacco particles having an average particle size of 30 micrometers and a dispersion medium for dispersing the tobacco particles is arranged in the filter segment.
  • the tobacco product is arranged in the filter segment before the assembly of the smoking article. This may either be carried out during the production of the filter segment or after the production of the filter segment but before arranging the filter segment in the smoking article. In this way, the manufacturing method remains fully flexible whether a filter segment with or without the tobacco product is arranged in the smoking article. Also, standard manufacturing processes, preferably for heat-not-burn smoking articles, can be used to manufacture the smoking article according to this invention, as the additional processing step of arranging the tobacco product in the filter segment is carried out in a separate step. This enables the most cost-effective way of production of the smoking article according to the invention.
  • At least one part of the filter segment comprises the shape of a hollow cylinder having an inner lateral area, wherein the tobacco product is arranged on at least a part of the inner lateral area by coating.
  • the tobacco product is coated onto the inner lateral area during the manufacturing of the at least one part of the filter segment or after the manufacture of this part of the filter segment.
  • the material of the one part of the filter segment is preferably laid out flat and the surface of the material, later becoming the inner lateral area, is coated with the tobacco product. Afterwards, the coated material is shaped into the shape of a hollow cylinder, wherein the area, coated at least in part with the tobacco product, forms the inner lateral area of the hollow cylinder.
  • the one part of the filter segment comprising the shape of the hollow cylinder is firstly manufactured and secondly its inner lateral area is coated with the tobacco product.
  • the filter segment before coating the inner lateral area with a tobacco product, is at least in part coated with a bonding agent.
  • the bonding agent is arranged between the inner lateral area surface and the tobacco product. Again, this can be carried out during production of the filter segment itself or after the production of the filter segment but before assembly of the smoking article.
  • the tobacco product is arranged on the filter material of at least a part of the filter segment by spraying, wherein the filter material is afterwards formed into the filter segment, which is subsequently arranged next to the cooling segment.
  • the filter material is afterwards formed into the filter segment, which is subsequently arranged next to the cooling segment.
  • the tobacco product is arranged on a thread, wherein the thread is then arranged on the filter material of at least a part of the filter segment which is afterwards formed into the filter segment which is subsequently arranged next to the cooling segment.
  • the thread comprising the tobacco product is arranged on the filter material by winding the filter material around the thread.
  • the filter material may be rolled around the thread. In this way, it is very easy to arrange the thread comprising the tobacco product in the filter material.
  • the subsequent arranging of the filter segment next to the cooling segment is not affected by the method of arranging the thread in the filter segment. In this way, the arranging of the filter segment next to the cooling segment can be carried out with standard production machinery.
  • the tobacco product is arranged on the thread by soaking the thread in the liquid tobacco product.
  • the tobacco product according to the invention comprises a liquid form. This liquid form is generated by the dispersion medium for dispersing the tobacco particles comprised in the tobacco product.
  • the tobacco product may dry on the respective surface.
  • the dispersion medium preferably partially evaporates. In other words, this means that before the tobacco product according to this invention is applied to any surface of the smoking article, it comprises a higher amount of the dispersion medium than present in the finished smoking article.
