Non-combustion heating type flavor inhalation article, and non-combustion heating type flavor inhalation system

Abstract

A non-combustion heating type flavor inhalation article includes: an aerosol-generating segment; and a mouthpiece segment adjacent to the aerosol-generating segment. The mouthpiece segment includes a filter material, and a breakable capsule within the filter material, the breakable capsule having a single-layered core-shell structure. The capsule is spherical or approximately spherical with a diameter of 3.0 mm to 4.5 mm. The capsule has a stress of 2 N or more and 6 N or less against a displacement of 0.5 mm within 4 minutes from 10 minutes of storage under a condition of 45° C. and 90% RH.

What is claimed is: 
     
         1 . A non-combustion heating type flavor inhalation article comprising:
 an aerosol-generating segment; and   a mouthpiece segment adjacent to the aerosol-generating segment, the mouthpiece segment comprising
 a filter material, and 
 a breakable capsule within the filter material, the breakable capsule having a single-layered core-shell structure, 
   wherein:   the capsule is spherical or approximately spherical with a diameter of 3.0 mm to 4.5 mm, and   the capsule has a stress of 2 N or more and 6 N or less against a displacement of 0.5 mm within 4 minutes from 10 minutes of storage under a condition of 45° C. and 90% RH.   
     
     
         2 . The non-combustion heating type flavor inhalation article according to  claim 1 ,
 wherein the capsule has a stress of 2.5 N or more and 6 N or less against the displacement of 0.5 mm within 4 minutes from the 10 minutes of storage under the condition of 45° C. and 90% RH.   
     
     
         3 . The non-combustion heating type flavor inhalation article according to  claim 1 ,
 wherein the capsule has a stress of 3 N or more and 20 N or less against a displacement of 1 mm within 4 minutes from the 10 minutes of storage under the condition of 45° C. and 90% RH.   
     
     
         4 . The non-combustion heating type flavor inhalation article according to  claim 3 ,
 wherein the capsule has a stress of 4 N or more and 20 N or less against the displacement of 1 mm within 4 minutes from the 10 minutes of storage under the condition of 45° C. and 90% RH.   
     
     
         5 . The non-combustion heating type flavor inhalation article according to  claim 1 ,
 wherein the capsule is breakable at a displacement of 1 mm or more and 2 mm or less.   
     
     
         6 . The non-combustion heating type flavor inhalation article according to  claim 1 ,
 wherein a ratio of a diameter of the capsule to a cross-section diameter of the filter material is 45% or more and 70% or less.   
     
     
         7 . The non-combustion heating type flavor inhalation article according to  claim 1 , wherein:
 a shell ratio of the capsule is 25 wt % or less, and   the capsule is a seamless member containing polysaccharide.   
     
     
         8 . The non-combustion heating type flavor inhalation article according to  claim 1 , wherein:
 the filter material comprises a layer filled with cellulose acetate long fibers plasticized by a plasticizer, and   a filling density of the cellulose acetate long fiber-filled layer is 130 [mg/cc] or less.   
     
     
         9 . The non-combustion heating type flavor inhalation article according to  claim 8 , wherein:
 a filament denier of the cellulose acetate long fiber-filled layer is 3.0 dpf or more and 12.0 dpf or less.   
     
     
         10 . The non-combustion heating type flavor inhalation article according to  claim 1 , wherein:
 the capsule comprises a shell containing gellan gum and starch.   
     
     
         11 . A non-combustion heating type flavor inhalation system comprising:
 the non-combustion heating type flavor inhalation article according to  claim 1 ; and   a heater configured to heat the aerosol-generating segment without burning.
