Abstract

A filter rod consumable for use in an aerosol provision system, wherein the filter rod consumable includes a filter, and, contained within the filter, an aerosolizable material including nicotine and one or more capsules including basic solution, wherein the basic solution can be released from the capsule to contact the aerosolizable material upon actuation by a user. Aerosol provision systems including a filter rod consumable, kits and related methods and uses.

Claims

exact text as granted — not AI-modified
1 . A filter rod consumable for use in an aerosol provision system, wherein the flavoring insert comprises a filter, and, contained within the filter:
 an aerosolizable material comprising nicotine; and   one or more capsules comprising basic solution,   wherein the basic solution can be released from the capsule to contact the aerosolizable material upon actuation by a user.   
     
     
         2 . A filter rod consumable as claimed in  claim 1 , wherein the aerosol provision system is a non-combustible aerosol provision system. 
     
     
         3 . A filter rod consumable as claimed in  claim 2 , wherein the non-combustible aerosol provision system is a hybrid system comprising an aerosol generating material which is to be heated to volatilize constituents, and a liquid which is to be heated to form a vapor. 
     
     
         4 . A filter rod consumable as claimed in  claim 1 , wherein the basic solution has a pH of from about 8 to about 10. 
     
     
         5 . A filter rod consumable as claimed in  claim 4 , wherein the basic solution has a pH of from about 8 to about 9. 
     
     
         6 . A filter rod consumable as claimed in  claim 1 , wherein the basic solution comprises one or more bases or a basic buffer system. 
     
     
         7 . A filter rod consumable as claimed in  claim 6 , wherein the one or more base is selected from the group consisting of hydroxides, carbonates and hydrogen carbonates. 
     
     
         8 . A filter rod consumable as claimed in  claim 1 , wherein the basic solution comprises a flavor. 
     
     
         9 . A filter rod consumable as claimed in  claim 1 , wherein the aerosolizable material comprises tobacco granules. 
     
     
         10 . A filter rod consumable as claimed in  claim 9 , wherein the aerosolizable material comprises one or more selected from the group consisting of: ground tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stem, tobacco lamina and reconstituted tobacco. 
     
     
         11 . A filter rod consumable as claimed in  claim 1 , wherein the aerosolizable material comprises one or more aerosol-former material. 
     
     
         12 . A filter rod consumable as claimed in  claim 11 , wherein the aerosol-former material is selected from the group consisting of glycerol, propylene glycol and glyceryl triacetate. 
     
     
         13 . A filter rod consumable as claimed in  claim 1 , wherein the filter comprises one or more filter material selected from group consisting of: cellulose acetate (CA), polyvinyl alcohol (PVOH), polylactic acid (PLA), polycaprolactone (PCL), poly(1-4 butanediol succinate) (PBS), poly(butylene adipate-co-terephthalate)(PBAT), starch based materials, cotton, aliphatic polyester materials and polysaccharide polymers. 
     
     
         14 . A filter rod consumable as claimed in  claim 1 , wherein the filter comprises a filamentary tow material. 
     
     
         15 . A filter rod consumable as claimed in  claim 14 , wherein the aerosolizable material is dispersed within the filter tow. 
     
     
         16 . A filter rod consumable as claimed in  claim 13 , wherein the one or more capsules comprising basic solution are surrounded by the filter material. 
     
     
         17 . A filter rod consumable as claimed in  claim 1 , wherein the filter includes a cavity between two spaced sections of filter material, and wherein the aerosolizable material is located in the filter cavity. 
     
     
         18 . A filter rod consumable as claimed in  claim 17 , wherein the one or more capsules comprising basic solution are located in the filter cavity. 
     
     
         19 . An aerosol provision system comprising a filter rod consumable as claimed in  claim 1 . 
     
     
         20 . A system as claimed in  claim 19 , wherein the system is an aerosol generating material heating system comprising an aerosol generating material which is to be heated to form an aerosol. 
     
     
         21 . A system as claimed in  claim 20 , wherein the system is a hybrid system comprising an aerosol generating material which is to be heated to volatilize constituents, and a liquid which is to be heated to form a vapor. 
     
     
         22 . A system as claimed in  claim 21 , wherein the aerosol generating material is heated by the vapor. 
     
     
         23 . A system as claimed in  claim 22 , wherein the liquid is a nicotine-free liquid. 
     
     
         24 . A system as claimed in  claim 22 , wherein the device includes a means for heating the liquid to form a vapor, but does not include a separate means for heating the aerosol generating material. 
     
     
         25 . A system as claimed in  claim 19 , wherein the aerosol generated by the system is drawn through the filter rod consumable. 
     
     
         26 . A system as claimed in  claim 19 , wherein the filter rod consumable forms the mouthpiece of the system. 
     
     
         27 . A kit comprising a filter rod consumable as claimed in  claim 1 , and a device for use in generating an inhalable aerosol. 
     
     
         28 . A method for modifying an aerosol generated by an aerosol provision system by drawing the aerosol through a filter rod consumable as claimed in  claim 1  . 
     
     
         29 . A method of generating an inhalable aerosol comprising actuating the one or more capsules comprising basic solution in a filter rod consumable as claimed in  claim 1 , and volatilizing components of the aerosolizable material to form the inhalable aerosol.
