Flavor containing sheet comprising modified cellulose and smoking article comprising the same

Abstract

Provided are: a fragrance-containing sheet for smoking articles, which includes moisture, modified cellulose, and fragrance such that fragrance can be dissolved at room temperature without a heating process; and a smoking article including the same.

1 . A fragrance-containing sheet for smoking articles, comprising:
 moisture;   modified cellulose; and   fragrance.   
     
     
         2 . The fragrance-containing sheet for smoking articles of  claim 1 , wherein, based on a total of 100 parts by weight, the moisture is 2 to 15 parts by weight, the modified cellulose is 25 to 90 parts by weight, and the fragrance is 0.1 to 60 parts by weight. 
     
     
         3 . The fragrance-containing sheet for smoking articles of  claim 1 , wherein the modified cellulose is hydroxypropyl methyl cellulose (HPMC), methyl cellulose (MC), carboxymethyl cellulose (CMC), or ethyl cellulose (EC). 
     
     
         4 . The fragrance-containing sheet for smoking articles of  claim 1 , further comprising a bulking agent. 
     
     
         5 . The fragrance-containing sheet for smoking articles of  claim 1 , further comprising an aerosol former or an emulsifier. 
     
     
         6 . The fragrance-containing sheet for smoking articles of  claim 1 , wherein the fragrance-containing sheet contains 1 wt % to 80 wt % of alcohol before being dried. 
     
     
         7 . The fragrance-containing sheet for smoking articles of  claim 1 , wherein the fragrance-containing sheet has a thickness of 0.01 mm to 0.3 mm. 
     
     
         8 . A smoking article comprising:
 a first portion comprising a tobacco material and a fragrance-containing sheet; and   a second portion comprising a filter element,   wherein the first portion and the second portion are arranged in series along a longitudinal direction of the smoking article, and   wherein the fragrance-containing sheet comprises modified cellulose.   
     
     
         9 . The smoking article of  claim 8 , wherein the fragrance-containing sheet contains, based on a total of 100 parts by weight, 2 to 15 parts by weight of moisture, 25 to 90 parts by weight of the modified cellulose, and 0.1 to 60 parts by weight of fragrance. 
     
     
         10 . The smoking article of  claim 8 , wherein the modified cellulose is hydroxypropyl methyl cellulose (HPMC), methyl cellulose (MC), carboxymethyl cellulose (CMC), or ethyl cellulose (EC). 
     
     
         11 . The smoking article of  claim 8 , wherein the fragrance-containing sheet further comprises a bulking agent. 
     
     
         12 . The smoking article of  claim 8 , wherein the fragrance-containing sheet further comprises an aerosol former or an emulsifier. 
     
     
         13 . The smoking article of  claim 8 , wherein the fragrance-containing sheet has a thickness of 0.01 mm to 0.3 mm. 
     
     
         14 . A combustion-type cigarette comprising:
 a first segment comprising a tobacco material and a fragrance-containing sheet; and   a second segment comprising a filter element,   wherein the first segment and the second segment are arranged in series along a longitudinal direction of the combustion-type cigarette, and   wherein the fragrance-containing sheet comprises modified cellulose.
