Smoking substitute consumable

Abstract

The present disclosure relates to an HNB consumable comprising an aerosol-forming substrate, the consumable having an axial length extending perpendicularly to a non-rectangular transverse end face. The axial length of the aerosol-forming substrate is greater than 45% of the axial length of the consumable and/or the volume of the aerosol-forming substrate is greater than 45% of the volume of the consumable.

What is claimed is: 
     
         1 . A HNB consumable comprising an aerosol-forming substrate, the consumable having an axial length extending perpendicularly to a non-rectangular transverse end face, wherein the volume of the aerosol-forming substrate is greater than 45% of the volume of the consumable. 
     
     
         2 . A consumable according to  claim 1  wherein the volume of the aerosol-forming substrate is greater than 50% of the axial length/volume of the consumable. 
     
     
         3 . A consumable according to  claim 2  wherein the axial volume of the aerosol-forming substrate is greater than 65% of the axial length/volume of the consumable. 
     
     
         4 . A consumable according to  claim 1  or  2  wherein the axial volume of the aerosol-forming substrate is between 50 and 70% of the axial length/volume of the consumable. 
     
     
         5 . A consumable according to any one of the preceding claims wherein the transverse end face has a polygonal shape such as a triangle, square, pentagon, hexagon, octagon etc. shape. 
     
     
         6 . A consumable according to any one of  claims 1  to  4  wherein at least a portion of the perimeter of the transverse end face is curved. 
     
     
         7 . A consumable according to  claim 6  wherein the transverse end face is substantially circular or oval. 
     
     
         8 . A consumable according to any one of  claims 1  to  7  having a transverse cross-sectional area that varies along the axial length. 
     
     
         9 . A consumable according to any one of the preceding claims having a transverse cross-sectional shape that varies along the axial length. 
     
     
         10 . A consumable according to any one of the preceding claims wherein the axial length of the consumable is less than 45 mm. 
     
     
         11 . A consumable according to any one of the preceding claims wherein the aerosol-forming substrate comprises a recess or bore extending axially from a downstream transverse end face. 
     
     
         12 . A consumable according to any one of the preceding claims further comprising at least one element selected from a filter element, a spacer element, a hollow bore element or a cooling element. 
     
     
         13 . A system comprising a smoking substitute article according to any one of the preceding claims and a device comprising a heating element. 
     
     
         14 . A system according to  claim 13  wherein the device comprises a main body for housing the heating element and the heating element comprises an elongated heating element. 
     
     
         15 . A method of using the system according to  claim 13  or  14 , the method comprising:
 inserting the article into the device; and 
 heating the article using the heating element.
