Aerosol generating system

Abstract

An aerosol generating system is provided. The aerosol generating system includes an aerosol generating apparatus and an aerosol forming article. The aerosol forming article includes a solid aerosol precursor, and wherein the aerosol precursor includes a plurality of strips of an aerosol forming substrate. At least one of the strips includes at least one embossed region to increase friction between strips. The aerosol generating apparatus includes a heating system including a heater for penetration into the precursor.

1 . An aerosol generating system including an aerosol generating apparatus and an aerosol forming article;
 wherein the aerosol forming article includes a solid aerosol precursor, and wherein the solid aerosol precursor includes a plurality of strips of an aerosol forming substrate, wherein each of substantially all of the strips includes a respective plurality of embossed regions;   wherein the aerosol generating apparatus includes a heating system including a heater for penetration into the solid aerosol precursor.   
     
     
         2 . A system according to  claim 1  wherein each of at least two of the strips includes a respective embossed region. 
     
     
         3 . A system according to  claim 2 , wherein the plurality of strips are substantially aligned within the precursor. 
     
     
         4 . A system according to  claim 2  wherein the precursor is elongated along a longitudinal axis, and an embossed region on a first embossed strip is longitudinally off set along the longitudinal axis from the second embossed region on a second embossed strip. 
     
     
         5 . A system according to  claim 4 , wherein the embossed region on the first embossed strip is located longitudinally between a pair of embossed regions on the second embossed strip. 
     
     
         6 . (canceled) 
     
     
         7 . (canceled) 
     
     
         8 . A system according to  claim 1  wherein each strip has a longitudinal strip length and a transverse strip width, the strip length being greater than the strip width, and wherein the or each embossed region is located between two longitudinal opposed edges of the respective strip. 
     
     
         9 . A system according to  claim 1 , wherein the or each embossed region is generally circular. 
     
     
         10 . A system according to  claim 1 , wherein the or each embossed region is generally elongate. 
     
     
         11 . A system according to  claim 1 , wherein the aerosol forming article includes an aperture immediately downstream of the precursor. 
     
     
         12 . A system according to  claim 9  wherein the aperture is an upstream lumen of a bore. 
     
     
         13 . A system according to  claim 10  wherein the bore is located through a porous filter material. 
     
     
         14 . A system according to  claim 1 , wherein each strip has a substantially equal transverse width. 
     
     
         15 . A system according to  claim 1 , wherein the heater has a rod shape or a blade shape.
