Aerosol-generating article comprising a wrapper with an overlapping region

Abstract

An aerosol-generating article ( 10 ) comprising an aerosol-forming substrate ( 11 ) and a wrapper ( 30 ) that circumscribes the aerosol-forming substrate. The wrapper defines an overlapping region ( 41 ) in which the wrapper overlaps itself, the overlapping region comprising a first section ( 42 ) and a second section ( 43 ) externally disposed on the first section. The second section comprises a fold ( 44 ) which defines a folded section ( 45 ) at one end of the wrapper, and the folded section is sandwiched between the first section and the second section. An outer adhesive is disposed between the folded section and the second section.

1 . An aerosol-generating article comprising:
 an aerosol-forming substrate; and   a wrapper that circumscribes the aerosol-forming substrate;   wherein the wrapper defines an overlapping region in which the wrapper overlaps itself, the overlapping region comprising a first section and a second section externally disposed on the first section;   wherein the second section comprises a fold which defines a folded section at one end of the wrapper;   wherein the folded section is sandwiched between the first section and the second section; and   wherein an outer adhesive is disposed between the folded section and the second section.   
     
     
         2 . The aerosol-generating article of  claim 1 , wherein an inner adhesive is disposed between the folded section and the first section. 
     
     
         3 . The aerosol-generating article of  claim 1 , wherein the outer adhesive comprises one or more of: gum Arabic, natural or synthetic resins, starch and varnish. 
     
     
         4 . The aerosol-generating article of  claim 1 , further comprising a heating element embedded within the aerosol-forming substrate. 
     
     
         5 . The aerosol-generating article of  claim 4 , wherein the heating element is an inductive susceptor. 
     
     
         6 . The aerosol-generating article of  claim 4 , wherein the heating element is completely surrounded by the aerosol-forming substrate and extends along an entire length of the aerosol-forming substrate. 
     
     
         7 . The aerosol-generating article of  claim 1 , wherein a diameter of the aerosol-generating article is between about 3 mm and about 8 mm. 
     
     
         8 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness between about 60 micrometres and about 200 micrometres. 
     
     
         9 . The aerosol-generating article of  claim 1 , wherein the aerosol-forming substrate comprises one or more of tobacco, nicotine, a gel composition and a flavour substrate. 
     
     
         10 . The aerosol-generating article of  claim 1 , further comprising a filter disposed downstream of the aerosol-forming substrate. 
     
     
         11 . The aerosol-generating article of  claim 1 , wherein a length of the aerosol-generating article is between about 30 mm and about 100 mm. 
     
     
         12 . An aerosol-generating system comprising:
 the aerosol-generating article of  claim 1 ; and   an aerosol-generating device.   
     
     
         13 . The aerosol-generating system of  claim 12 , wherein the aerosol-generating device comprises a resistive heating element. 
     
     
         14 . The aerosol-generating system of  claim 12 , wherein the aerosol-generating device comprises an inductor coil. 
     
     
         15 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness between about 78 micrometres and about 160 micrometres. 
     
     
         16 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness between 78 micrometres and about 140 micrometres. 
     
     
         17 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness between about 100 micrometres and about 140 micrometres. 
     
     
         18 . The aerosol-generating article of  claim 1 , wherein the wrapper has a thickness between about 125 micrometres and about 140 micrometres.
