Tobacco Article Comprising a Viscous Vaporizable Material and Associated Aerosol Generating Device and Assembling Method

Abstract

A tobacco article comprising a viscous vaporizable material and a support. The support may be formed from one or several rigid sheets arranged or bent to retain the viscous vaporizable material and to form an airflow path.

1 . A tobacco article comprising:
 a viscous vaporizable material; and   a support, the support being formed from one or more rigid sheets arranged or bent to retain the viscous vaporizable material and to form an airflow path.   
     
     
         2 . The tobacco article according to  claim 1 , wherein at least one of the one or more rigid sheets is made of metal. 
     
     
         3 . The tobacco article according to  claim 1 , wherein at least one of the one or more rigid sheets is bent to form a cylindrical shape, advantageously having a circular cross-section. 
     
     
         4 . The tobacco article according to  claim 3 , wherein the one or more rigid sheets comprises an outer sheet and an inner sheet, the viscous vaporizable material being retained between said the inner sheet and the outer sheets. 
     
     
         5 . The tobacco article according to  claim 4 , wherein the inner sheet delimits the airflow path. 
     
     
         6 . The tobacco article according to  claim 4 , wherein the inner sheet is perforated. 
     
     
         7 . The tobacco article according to any one of  claims 4 , wherein the outer sheet forms a unique outer sheet and the inner sheet forms a unique inner sheet of the article. 
     
     
         8 . The tobacco article according to  claim 4 , wherein the viscous vaporizable material is in direct contact with the outer sheet. 
     
     
         9 . The tobacco article according to  claim 1 , further comprising a gauze sheet interposed between the vaporizable material and at the one or more rigid sheets. 
     
     
         10 . The tobacco article according to  claim 1 , further comprising an external wrapper assembling the one or more or rigid sheets with a filter/cooling portion. 
     
     
         11 . The tobacco article according to  claim 1 , wherein the viscous vaporizable material comprises a solid content and a liquid content, the ratio of the solid content being between 80% and 120% of the liquid content; 
     
     
         12 . The tobacco article according to  claim 11 , wherein the liquid content comprises glycerine. 
     
     
         13 . The tobacco article according to  claim 12 , wherein the ratio of glycerine is between 50% and 100% of the liquid content. 
     
     
         14 . The tobacco article according to  claim 1 , wherein the viscous vaporizable material forms a unique layer of vaporizable material in the article. 
     
     
         15 . An aerosol generating device comprising a cavity configured to receive and heat the tobacco article according to  claim 1 . 
     
     
         16 . The aerosol generating device according to  claim 15 , wherein the cavity is configured to receive and heat simultaneously at least two tobacco articles, the airflow path of one of the tobacco articles ( 14 ) extending the airflow path of the other tobacco article. 
     
     
         17 . (canceled) 
     
     
         18 . The tobacco article according to  claim 11 , wherein the solid content comprises ground tobacco. 
     
     
         19 . The tobacco article according to  claim 12 , wherein the glycerine comprises propylene glycol and water. 
     
     
         20 . The tobacco article according to  claim 12 , wherein:
 the ratio of propylene glycol is between 0% and 50% of the liquid content, and   the ratio of water is between 0% and 20% of the liquid content.
