Definitions

  • the present invention relates to a non-combustion heating type flavor inhalation article.
  • a flavor inhalation article includes a tipping paper that joins a tobacco rod and another member.
  • tipping papers with various functions imparted have been proposed.
  • PTL 1 discloses a smoking article in which a tipping paper in the outermost layer is attachable/detachable. It is said that the attachable/detachable tipping paper can provide an appearance or a sensory change to the user.
  • PTL 2 discloses that a material or the like for imparting cushioning properties is wrapped two times around a mouthpiece.
  • a non-combustion heating type flavor inhalation article generates an aerosol when a tobacco rod is heated. At this time, a tipping paper wrapped around the tobacco rod is deteriorated by heating. As a result, the non-combustion heating type flavor inhalation article is torn or broken, and the handleability is impaired in some cases.
  • an object of the present invention is to provide a non-combustion heating type flavor inhalation article that is excellent in handleability after heating.
  • a tipping paper has been used so that its CD direction is parallel to the longitudinal direction of the flavor inhalation article.
  • the inventors have found that the above-described problem can be solved by changing the orientation of the tipping paper. That is, the above-described problem is solved by the present invention as follows.
  • a non-combustion heating type flavor inhalation article includes a tipping paper that joins a tobacco rod and an adjacent member adjacent to the tobacco rod.
  • An MD direction of the tipping paper is substantially parallel to a longitudinal direction of the non-combustion heating type flavor inhalation article.
