Abstract

The present disclosure relates to a component for a delivery system. The component comprises a body of material, a plurality of aerosol-modifying agent capsules in the body of material, and a plurality of particles in the body of material. The aerosol-modifying agent capsules and/or particles are interspersed within the body of material. The particles are configured such that, in use, the particles promote breaking of the aerosol-modifying agent capsules upon the application of an external force to the aerosol provision system component by a user.

Claims

exact text as granted — not AI-modified
1 . A component for a delivery system, the component comprising:
 a body of material;   a plurality of aerosol-modifying agent capsules in the body of material; and,   a plurality of particles in the body of material, wherein the aerosol-modifying agent capsules and/or particles are interspersed within the body of material, the particles configured such that, in use, the particles promote breaking of the aerosol-modifying agent capsules upon the application of an external force to the aerosol provision system component by a user.   
     
     
         2 . A component according to  claim 1 , wherein the aerosol-modifying agent capsules are interspersed within the body of material. 
     
     
         3 . A component according to  claim 1 , wherein the particles are interspersed within the body of material. 
     
     
         4 . A component according to  claim 1 , wherein the body of material comprises a cavity, and wherein the aerosol-modifying agent capsules or particles are disposed within the cavity. 
     
     
         5 . A component according to  claim 1 , wherein each capsule comprises a core and a shell that surrounds the core. 
     
     
         6 . A component according to  claim 1 , wherein the particles are generally cylindrical. 
     
     
         7 . A component according to  claim 1 , wherein the material of the body of material has a mass of at most 5.5 mg per mm axial length of the body of material. 
     
     
         8 . A component according to  claim 1 , having a diameter greater than 7.5 mm. 
     
     
         9 . A component according to  claim 1 , wherein the particles comprise a material having a particle density of at least 1 g/cc. 
     
     
         10 . A component according to  claim 1 , wherein the particles comprise a plasticiser. 
     
     
         11 . A component according to  claim 1 , wherein the particles comprise a polymeric material. 
     
     
         12 . A component according to  claim 1 , wherein the particles comprise cellulose acetate. 
     
     
         13 . A component according to  claim 1 , wherein the aerosol-modifying agent capsules have a diameter in the range of 0.6 and 1.4 mm. 
     
     
         14 . A component according to  claim 1 , wherein the particles have a particle size in the range of 0.6 and 2.4 mm. 
     
     
         15 . A component according to  claim 1 , comprising in the range of 5 to 100 aerosol-modifying agent capsules. 
     
     
         16 . A component according to  claim 1 , wherein the body of material has a length in the range of 4 and 12 mm. 
     
     
         17 . A component according to  claim 1 , wherein the pressure drop across the body of material is less than 40 mmWg. 
     
     
         18 . A component according to  claim 1 , further comprising a plug wrap that circumscribes the body of material and is held in place by an adhesive. 
     
     
         19 . A component according to  claim 18 , wherein the body of material, plug wrap, adhesive, aerosol-modifying agent capsules and particles together have a mass of at most 20 mg per mm axial length of the body of material. 
     
     
         20 . A component according to  claim 1 , wherein the body of material comprises a fibrous material. 
     
     
         21 . A component according to  claim 20 , wherein the fibrous material comprises a tow comprising cellulose acetate, 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 or a combination thereof. 
     
     
         22 . A component according to  claim 20 , wherein the total denier of the fibrous material is at 35000. 
     
     
         23 . A component according to  claim 20 , wherein the denier per filament of the fibrous material is at most 9. 
     
     
         24 . A component according to  claim 20 , wherein the denier per filament of the fibrous material is at least 1. 
     
     
         25 . A component according to  claim 1 , wherein the fibrous material comprises at least 1000 fibres. 
     
     
         26 . A component according to  claim 1 , wherein the fibrous material comprises at most 12000 fibres.
