Abstract

Provided is a tobacco sheet for a non-combustion heating-type flavor inhaler including a tobacco material, wherein a cross-section of the tobacco sheet in the thickness direction has a wavy shape.

Claims

exact text as granted — not AI-modified
1 . A tobacco sheet for a non-combustion heating-type flavor inhaler, wherein the tobacco sheet contains a tobacco raw material and has a wavy shape in a cross-section in a thickness direction,
 wherein at least one of an arcuate curved surface present on a front surface and an arcuate curved surface present on a back surface of the sheet has a surface arithmetic mean surface roughness Sa in the range of 5 to 30 μm.   
     
     
         2 . (canceled) 
     
     
         3 . The sheet according to  claim 1 , which is a press-formed sheet. 
     
     
         4 . The sheet according to  claim 1 , comprising a cellulose derivative with a degree of substitution of 0.65 or more. 
     
     
         5 . The sheet according to  claim 4 , wherein the degree of substitution is 0.7 or more. 
     
     
         6 . A non-combustion heating-type flavor inhaler comprising a tobacco-containing segment containing the tobacco sheet for a non-combustion heating-type flavor inhaler according to  claim 1 . 
     
     
         7 . A non-combustion heating-type flavor inhaling system comprising:
 the non-combustion heating-type flavor inhaler according to claim  6 ; and   a heating device for heating the tobacco-containing segment.   
     
     
         8 . A method for manufacturing the tobacco sheet according to  claim 1 , comprising:
 preparing a mixture containing the tobacco raw material, an aerosol generator, a first shaping agent, and a second shaping agent;   rolling the mixture to form a rolled product; and   pressing a rotary roll blade against the rolled product to cut the rolled product into a strip while imparting a wavy shape to the strip.
