Flavor inhalation article

Abstract

A flavor inhalation article 1 comprises: a flavor element 2 which is heated without involving combustion; and a tubular element 4 which forms an airflow channel. The tubular element 4 is equipped with a cylindrical hollow paper tube 26 and a paper liner 28 disposed inside the paper tube 26 in such a manner as to lie along the axial direction X of the paper tube 26. The total of the cross-sectional length of the liner 28 in the diametrical direction Y of the paper tube 26 is greater than the inner diameter d of the paper tube 26.

1 . A flavor inhaling article comprising: a flavor element to be heated without burning; and a tubular element having an airflow path, wherein
 the tubular element includes
 a hollow paper core having a cylindrical shape, and 
 a paper liner disposed in the paper core over the paper core in an axis direction, and 
 a total cross-sectional length of the liner in a tube radial direction of the paper core is greater than an inside diameter of the paper core. 
   
     
     
         2 . The flavor inhaling article according to  claim 1 , wherein the tubular element is disposed adjacent to the flavor element. 
     
     
         3 . The flavor inhaling article according to  claim 1 , wherein an additive is sorbed to the liner. 
     
     
         4 . The flavor inhaling article according to  claim 1 , wherein an area of the liner, which can contact with an inner periphery of the paper core, is bonded to the inner periphery of the paper core over the liner in the axis direction. 
     
     
         5 . The flavor inhaling article according to  claim 1 , wherein a paper thickness of the liner ranges from 0.05 mm to 1 mm. 
     
     
         6 . The flavor inhaling article according to  claim 1 , wherein a basis weight of the liner ranges from 80 gsm to 120 gsm. 
     
     
         7 . The flavor inhaling article according to  claim 1 , wherein a total cross-sectional length of the liner in the tube radial direction is greater than or equal to twice the inside diameter of the paper core. 
     
     
         8 . The flavor inhaling article according to  claim 1 , wherein a cross section of the liner in the tube radial direction has an S-shape.
