Shisha cartridge with absorbent carrier

Abstract

A shisha cartridge (200) comprises a body defining a cavity (218). An aerosol-forming substrate (300) and an absorbent carrier (310) forming a sheet impregnated with an aerosol former are disposed in the cavity. The absorbent carrier may be disposed adjacent or in contact with the internal cavity surface, the aerosol-forming substrate, or both the internal cavity surface and the aerosol-forming substrate. As the cartridge is heated, the aerosol former impregnated in the absorbent carrier may improve aerosol formation.

1 . A shisha cartridge comprising:
 a body comprising a cavity and an internal cavity surface;   an aerosol-forming substrate disposed in the cavity;   an absorbent carrier disposed in the cavity; and   an aerosol former impregnated into the absorbent carrier.   
     
     
         2 . A shisha cartridge according to  claim 1 , wherein the aerosol former comprises glycerine, propylene glycol, or a combination thereof. 
     
     
         3 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier comprises from 0.1 g to 8 g of the aerosol former. 
     
     
         4 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier is adjacent the internal cavity surface, the aerosol-forming substrate, or both the internal cavity surface and the aerosol-forming substrate. 
     
     
         5 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier is in direct contact with the internal cavity surface. 
     
     
         6 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier comprises refined cellulosic material. 
     
     
         7 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier comprises paper. 
     
     
         8 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier sheet is pleated. 
     
     
         9 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier has a thickness of 0.1 mm to 5 mm. 
     
     
         10 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier has a surface area of 2 cm 2  to 50 cm 2 . 
     
     
         11 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier and the aerosol-forming substrate form a spiral of alternating layers of absorbent carrier and aerosol-forming substrate. 
     
     
         12 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier is lined with a thermally conductive or inductive material. 
     
     
         13 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier forms a sheet. 
     
     
         14 . A shisha cartridge according to  claim 1 , wherein the absorbent carrier comprises a cylindrical portion disposed along an internal side wall of the cavity. 
     
     
         15 . A shisha system comprising:
 a shisha cartridge according to  claim 1 ; and   a shisha device comprising:   a receptacle for receiving the cartridge;   a heating element for heating the aerosol-generating substrate when the cartridge is received in the receptacle of the shisha device;   a vessel having a liquid fill level and defining a head space above the liquid fill level;   an aerosol conduit for conveying aerosol from the receptacle to below the liquid fill level in the vessel; and   an outlet in communication with the head space.
