Aerosol generating article and method of manufacturing the same

Abstract

A non-combustion-type aerosol generating article according to an embodiment includes a first filter segment, a medium segment disposed downstream of the first filter segment, and a second filter segment disposed downstream of the medium segment, in which the medium segment has a longitudinal hollow and is manufactured by being solidified after medium slurry is molded into a cylindrical shape.

1 . An aerosol generating article comprising:
 a first filter segment;   a medium segment disposed downstream of the first filter segment; and   a second filter segment disposed downstream of the medium segment,   wherein the medium segment has a longitudinal hollow and the medium segment is configured by being solidified after medium slurry comprising a medium is molded into a tube shape.   
     
     
         2 . The aerosol generating article of  claim 1 , further comprising:
 a cooling segment between the medium segment and the second filter segment.   
     
     
         3 . The aerosol generating article of  claim 1 , wherein the medium comprises at least one of reconstituted tobacco sheet, cut leaves, caffeine, taurine, pharmacological materials, flavor materials, or sweeteners. 
     
     
         4 . The aerosol generating article of  claim 3 , wherein the medium slurry has moisture content greater than or equal to 30 percent. 
     
     
         5 . The aerosol generating article of  claim 4 , wherein the medium slurry has moisture content less than 60 percent. 
     
     
         6 . The aerosol generating article of  claim 3 , wherein the medium slurry is molded into a tube shape with an inner diameter greater than or equal to ½ of an outer diameter. 
     
     
         7 . The aerosol generating article of  claim 3 , wherein the medium slurry is molded into a tube shape with a hollow by extrusion. 
     
     
         8 . A method of manufacturing the aerosol generating article according to  claim 1 , the method comprising:
 providing medium slurry comprising a medium;   molding the medium slurry into a tube shape;   forming a medium segment by drying the medium slurry; and   coupling a first filter segment to upstream of the medium segment and coupling a second filter segment to downstream of the medium segment,   wherein the medium slurry has moisture content greater than or equal to 30 percent and less than 60 percent.   
     
     
         9 . The method of  claim 8 , wherein, in the molding of the medium slurry into the tube shape, the medium slurry is molded into a tube shape by extrusion. 
     
     
         10 . The method of  claim 8 , wherein, in the molding of the medium slurry into the tube shape, a second jig with a through hole corresponding to an outer shape of the medium segment is coupled to a first jig comprising a rod member with an outer shape corresponding to a hollow of the medium segment, the medium slurry is filled between the through hole of the second jig and the rod member, and the medium slurry molded into the tube shape is separated from the first jig and the second jig.
