Flat-Shaped Tobacco Article Comprising a First Gap and a Second Gap, and Associated Aerosol Generating Device and Assembly

Abstract

A flat-shaped tobacco article configured to operate with an aerosol generating device and extending along an article axis between a mouth end and an abutting end includes a mouthpiece portion adjacent to the mouth end and a tobacco portion adjacent to the abutting end, the tobacco portion including a substrate layer forming two opposite sides, and a wrapper forming an internal surface and arranged around the substrate layer so as its internal surface forms a first gap with one of the sides of the substrate layer and a second gap with the other side of the substrate layer, each of the first gap and the second gap being adapted to receive a heating blade of the aerosol generating device.

1 . A flat-shaped tobacco article configured to operate with an aerosol generating device and extending along an article axis between a mouth end and an abutting end, the tobacco article comprising a mouthpiece portion adjacent to the mouth end and a tobacco portion adjacent to the abutting end;
 the tobacco portion comprising:
 a substrate layer extending along the article axis and forming two opposite sides; and 
 a wrapper forming an internal surface and arranged around the substrate layer so as its such that the internal surface forms a first gap with one of the sides of the substrate layer and a second gap with the other side of the substrate layer; 
 each of the first gap and the second gap being adapted to receive a heating blade of the aerosol generating device. 
   
     
     
         2 . The flat-shaped tobacco article according to  claim 1 , wherein the first gap is thicker than the second gap. 
     
     
         3 . The flat-shaped tobacco article according to  claim 2 , wherein the second gap is adapted to receive the heating blade of the aerosol generating device se as such that the heating blade is in contact with the corresponding side of the substrate layer. 
     
     
         4 . The flat-shaped tobacco article according to  claim 2 , wherein the first gap is adapted to receive the heating blade of the aerosol generating device se such that the heating blade is spaced from the corresponding side of the substrate layer. 
     
     
         5 . The flat-shaped tobacco article according to  claim 1 , wherein the mouthpiece portion comprises a core and a wrapper forming an internal surface and arranged around the core such that the entire internal surface of the wrapper of the mouthpiece portion is in contact with the core. 
     
     
         6 . The flat-shaped tobacco article according to  claim 5 , wherein the wrapper of the mouthpiece portion and the wrapper of the tobacco portion are formed by a same wrapping sheet. 
     
     
         7 . The flat-shaped tobacco article according to  claim 5 , wherein the core comprises corrugated paper. 
     
     
         8 . The flat-shaped tobacco article according to  any one of the preceding claim 1 , wherein the wrapper is made from paper. 
     
     
         9 . The flat-shaped tobacco article according to  claim 1 , wherein the first gap and the second gap are the only gaps adapted to receive the heating blade of the aerosol generating device. 
     
     
         10 . An aerosol generating device comprising a heating chamber extending along a device axis between a closed end and an opening;
 the heating chamber being configured to receive through the opening the flat-shaped tobacco article according to  claim 1 , and comprising a heating blade extending from the closed end and configured to be received in the first gap of the flat-shaped tobacco article or in the second gap of the flat-shaped tobacco article.   
     
     
         11 . The aerosol generating device according to  claim 10 , wherein the heating blade is adapted to heat the substrate layer by conduction heating when the heating blade is received in the second gap of the flat-shaped tobacco article and by convection heating when the heating blade is received in the first gap of the flat-shaped tobacco article. 
     
     
         12 . The aerosol generating device according to  claim 10 , wherein the heating blade forms two opposite sides and comprises a heating element arranged on one of the sides;
 the heating element being configured to be in contact with the substrate layer when the heating blade is received in the second gap of the flat-shaped tobacco article and spaced from the substrate layer when the heating blade is received in the first gap of the flat-shaped tobacco article.   
     
     
         13 . The aerosol generating device according to  claim 10 , wherein the heating chamber comprises two parallel opposite walls extending along the device axis, the heating blade extending parallel to said opposite walls with uneven distances until these walls. 
     
     
         14 . The aerosol generating device according to  claim 13 , wherein the heating blade extends between one of said opposite walls and a plane arranged at mid-distance between these opposite walls. 
     
     
         15 . (canceled)
