This makes it possible to prevent the steam or aerosol generated in the flavor source 121 (described below) contained in the flavor generating segment 120 from leaking from the upstream side of the flavor generating article 100.
  • the longitudinal length of the plug portion 111 is preferably 10 mm or less, and more preferably 8 mm or less. If the plug portion 111 is short, the flavor generating article 100 can be configured compactly. On the other hand, if the plug portion 111 is too short, it becomes difficult to manufacture the first segment 110 or connect it to other segments, so the longitudinal length of the plug portion 111 is preferably 5 mm or more. In other words, the longitudinal length of the plug portion 111 is preferably 5 mm or more and 10 mm or less.

  • the unit is generally expressed in mmH 2 O.
  • the airflow resistance changes depending on the length of the object.
  • the airflow resistance per unit length of the plug portion 111 is preferably 2.5 mmH 2 O/mm or less. Small airflow resistance makes it easier for the user to inhale. On the other hand, if the airflow resistance is too small, there is a risk that the steam or aerosol generated in the flavor source 121 will leak from the upstream side of the flavor generating article 100, or that the delivery of flavor components will be reduced at the beginning of heating, etc., due to the introduction of air into a portion of the first segment 110 that is not directly heated. Therefore, the airflow resistance per unit length of the plug portion 111 is preferably 0.3 mmH 2 O/mm or more.
  • the airflow resistance per unit length of the plug portion 111 is preferably 0.3 mmH2O /mm or more and 2.5 mmH2O /mm or less.

  • the downstream end of the heater 40 is upstream of the through hole 132, and it is preferable that the protruding length of the heater 40 is 1 mm or more and 5 mm or less. If the protruding length of the heater 40 is less than 1 mm, there is a risk that the effect of suppressing aggregation may not be sufficiently obtained. Also, if the protruding length of the heater 40 is longer than 5 mm, there is a risk that the vapor or aerosol generated in the flavor source 121 may not be sufficiently cooled in the hollow tube 131.
  • the second segment 140 is a segment disposed on the second end 102 side of the cooling segment 130.
  • the second segment 140 has a first filter 141 and a second filter 142 aligned in the longitudinal direction, and an outer plug wrapper 350 that covers the first filter 141 and the second filter 142.
  • the second segment 140 is not particularly limited as long as it has a filter function such as adjusting the air flow during flavor inhalation or adjusting the amount of flavor or other impurities.
  • the second segment 140 can also function as a rear plug that prevents members on the first end 101 side of the second segment 140 from falling off.
  • the position of the first filter 141 is not limited to the position shown in FIG. 4, and for example, the positions of the first filter 141 and the second filter 142 may be interchanged.
  • the second filter 142 may be omitted, and the second segment 140 may include three or more filters.
  • the first filter 141 has a filler 310 and a cylindrical first inner plug wrapper 320 that encases the filler 310.
  • the first filter 141 is preferably solid.
  • the filler 310 is not particularly limited as long as it is a filtering material, and can be a fibrous material or a porous material.
  • the filler 310 can be, for example, cellulose acetate fiber, paper, nonwoven fabric, etc.
  • the second filter 142 is composed of a filling layer 330 having a hollow portion and a second inner plug wrapper 340 that covers the filling layer 330.
  • the filling layer 330 can be, for example, a rod filled with cellulose acetate fibers at a high density and hardened by adding a plasticizer containing triacetin.
  • the second inner plug wrapper 340 may be omitted.
  • the diameter of the hollow portion is not particularly limited, but may be, for example, 1.0 mm to 5.0 mm. Because the packed fiber density of the packed layer 330 is high, air or aerosol flows only through the hollow portion during inhalation, with almost no flow within the packed layer 330.

Abstract

L'invention concerne un article de génération d'arôme. Cet article de génération d'arôme est au moins partiellement reçu dans un inhalateur d'arôme, et est pourvu d'une source d'arôme qui génère un arôme lorsqu'il est chauffé. La source d'arôme a une première partie qui chevauche un dispositif de chauffage dans l'inhalateur d'arôme et une seconde partie qui ne chevauche pas le dispositif de chauffage dans l'inhalateur d'arôme dans la direction longitudinale de l'article de génération d'arôme lorsque l'article de génération d'arôme est reçu dans une position souhaitée de l'inhalateur d'arôme. La longueur de la première partie dans la direction longitudinale est comprise entre 40 et 60% de la longueur dans la direction longitudinale de la source d'arôme, et est de 10 mm ou moins.
