Definitions

  • the present invention relates to a smoking article out of the field of heat-not-burn products with a heated section comprising a tobacco product for an intensive smoking experience with full of a tobacco taste.
  • the invention relates also to a method for manufacturing the mentioned smoking article.
  • US20040020504A1 discloses a sidestream smoke cigarette comprising a conventional tobacco rod and a combustible treatment paper having a sidestream smoke treatment composition.
  • the paper is coated by the treatment composition, which is sprayed on the paper.
  • CN105002785A discloses a lining paper for cigarettes, wherein the surface of a base paper is coated with a coating liquid containing tobacco extract as a main solute. This document discloses also a packaging material for the cigarettes to prevent moisture, mildew and aroma loss.
  • WO 2020/025562 A1 relates to a smoking article comprising a reconstituted tobacco binder.
  • a smoking article for enabling the user to conveniently an effectively incorporate a desired tobacco flavor to the aerosol prior to inhalation. It would be particularly desirable if such a smoking article could be adapted to enable the user to select from a variety of different tobacco flavors and flavor intensities. Preferably, such a smoking article could be manufactured with common handling machines.
  • a smoking article with a distal and a mouth end.
  • the smoking article has a cylindrical shape and is extending in a circumferential direction and a longitudinal direction.
  • at least one heated segment comprising tobacco and/or reconstituted tobacco binder (RTB)
  • at least one cooling segment comprising a cylindrically shaped cooler material and a filter segment are arranged, thereby creating a flow path from the distal to the mouth end.
  • the heated segment, the cooling segment and the filter segment are at least in part enclosed by a first wrapper, wherein the heated segment comprises 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 ⁇ m and a dispersion medium for dispersing the tobacco particles.
  • Applying tobacco product comprising tobacco particles to the second wrapper of the heated section enhances the tobacco taste experience of a customer.
  • the tobacco particles are inhaled together with the actual tobacco aerosol. This creates an additional strengthening of the tobacco taste.
  • the enhancement of the tobacco taste by adding the tobacco product is adjustable by the amount of the tobacco product.
  • Tobacco particles having such a small average particle size are providing a high surface area, which could be contacted by the passing aerosol. This allows transfer of the molecules from the particles into the aerosol stream.
  • the particle size of ⁇ 30 ⁇ m has been found to allow transfer of a plurality of flavoring molecules, which contribute to a full tobacco flavor.
  • the particle size allows migration of bigger and smaller molecules from an internal volume of the particles to their surface from which these molecules could pass over to the aerosol stream.
  • tobacco product refers to a flavoring substance comprising tobacco particles having an average particle size (sD50 laser diffraction) ⁇ 30 ⁇ m.
  • nicotine could pass over from the tobacco particles to the aerosol in a similar way. Since nicotine has a flavor and is usually a constituent of tobacco, the term “flavoring molecules" also includes nicotine.

It has been found, that grinding of the tobacco particles to a smaller particle size could affect the flavor. It is believed that some of the flavoring molecules of the leaf tobacco decompose due to the high shear energy. Furthermore, some flavoring molecules could exit very small tobacco particles during the grinding process or during a later handling process. This would result in a depletion of these flavoring molecules in the tobacco particles and a flavor composition different with respect to the full tobacco flavor.
  • a solvent is preferably selected from a group comprising water, monovalent alcohols, polyvalent alcohols, sugar alcohols, sugars and polyvalent alcohol esters.

  • the tobacco product 11 is applied to the inner 14 and/or the outer 13 surface of the second wrapper 6 with a spraying nozzle. If the tobacco product 11 is arranged 100 on the surfaces 13 and /or 14 in a pattern 17, the pattern 17 is either achieved by placing a mask between the spraying nozzle and the surface 13 and/or 14 or by moving the spraying nozzle with respect to the surface 13 and/or 14, following the desired pattern 17.
  • the tobacco product 11 is coated 100 on the surface 13 and/or 14 by printing 101
  • the tobacco product 11 is applied to the surface 13 and/or 14 of the second wrapper 6 preferably with a print roller.
  • the print roller may comprise recessed surface parts.

Preferably the applying step 102 takes place before the standard manufacturing process of the smoking article 8. It is also conceivable that the applying step 102 in the manufacturing process takes place after the standard manufacturing process of the smoking article 8.
