Cartridge for inductively heated aerosol-generating device

Abstract

The invention relates to a cartridge for an aerosol-generating device. The cartridge comprises a distal region comprising a liquid storage portion for holding a liquid aerosol-forming substrate, a proximal region comprising a hollow tubular susceptor element, and a wick element comprising a distal part and a proximal part. At least a portion of the distal part of the wick element extends into the liquid storage portion. At least a portion of the proximal part of the wick element is coaxially circumscribed by the susceptor element. The invention further relates to an aerosol-generating system.

1 . A cartridge for use with an aerosol-generating device, comprising
 a distal region comprising a liquid storage portion for holding a liquid aerosol-forming substrate;   a proximal region comprising a hollow tubular susceptor element; and   a wick element comprising a distal part and a proximal part;   wherein at least a portion of the distal part of the wick element extends into the liquid storage portion; wherein at least a portion of the proximal part of the wick element is coaxially circumscribed by the susceptor element; wherein the hollow tubular susceptor element comprises a transversally extending disk-shaped rim at a distal end thereof; and wherein the transversally extending disk-shaped rim of the hollow tubular susceptor element is fixed to a transversally extending wall element of a housing of the cartridge.   
     
     
         2 . The cartridge according to  claim 1 , wherein the wick element has an elongate cylindrical shape. 
     
     
         3 . The cartridge according to  claim 1 , wherein the proximal region of the cartridge comprises a proximal outer sidewall coaxially surrounding the susceptor element to form a cavity between the proximal sidewall and the susceptor element. 
     
     
         4 . The cartridge according to  claim 3 , comprising one or more air inlets provided in the proximal sidewall. 
     
     
         5 . The cartridge according to  claim 4 , wherein the one or more air inlets are arranged at a distal portion of the proximal sidewall. 
     
     
         6 . The cartridge according to  claim 1 , wherein the transversally extending disk-shaped rim of the hollow tubular susceptor element is fixed to the transversally extending wall element of the housing of the cartridge by means of an adhesive layer arranged between the disk-shaped rim and the wall element. 
     
     
         7 . The cartridge according to  claim 1 , wherein the hollow tubular susceptor element comprises an inclined proximal end face. 
     
     
         8 . The cartridge according to  claim 1 , wherein the cartridge comprises an open proximal end. 
     
     
         9 . The cartridge according to  claim 1 , wherein the proximal region of the cartridge comprises a proximal coupling means for removably attaching the cartridge to an aerosol-generating device. 
     
     
         10 . The cartridge according to  claim 1 , wherein the proximal region of the cartridge has a cylindrical outer shape, and wherein the wick element extends along a center axis of the cylindrical proximal region. 
     
     
         11 . An aerosol-generating system, comprising
 a cartridge according to  claim 1 ; and   an aerosol-generating device comprising a heating chamber at least partly circumscribed by an inductor coil, wherein the heating chamber comprises a proximal region for insertion of at least a portion of an aerosol-generating article and a distal region for insertion of at least a portion of the proximal region of the cartridge.   
     
     
         12 . The aerosol-generating system according to  claim 11 , comprising an aerosol-generating article comprising a solid aerosol-forming substrate. 
     
     
         13 . The aerosol-generating system according to  claim 12 , wherein the aerosol-generating article has a cylindrical outer shape, wherein the proximal region of the cartridge has a hollow cylindrical outer shape, and wherein the outer diameter of the cylindrical article is smaller than the inner diameter of the hollow cylindrical proximal region of the cartridge for allowing insertion of a distal end of the article into at least a portion of the hollow cylindrical proximal region of the cartridge. 
     
     
         14 . The aerosol-generating system according to  claim 12 , wherein the aerosol-generating article comprises a recess at a distal end thereof for insertion of at least a portion of the hollow tubular susceptor element of the cartridge.
