Abstract

An article for use as part of a non-combustible aerosol provision system, the article including a housing having a first section and a second section which together form a reservoir for an aerosolizable material, the first section and the second section being connected together to provide at least one pair of opposing surfaces; wherein a capillary channel is provided between the opposing surfaces, and at least one of the opposing surfaces includes at least one surface feature for inhibiting or preventing capillary flow of an aerosolizable material from the reservoir through the capillary channel.

1 . An article for use as part of a non-combustible aerosol provision system, the article comprising:
 a housing having a first section and a second section which together form a reservoir for an aerosolizable material, the first section and the second section being connected together to provide at least one pair of opposing surfaces;   wherein a capillary channel is provided between the opposing surfaces, and at least one of the opposing surfaces comprises at least one surface feature for inhibiting or preventing capillary flow of an aerosolizable material from the reservoir through the capillary channel.   
     
     
         2 . An article as claimed in  claim 1 , wherein one of the first section and the second section at least partially surrounds the other of the first section and the second section. 
     
     
         3 . An article as claimed in  claim 1 , wherein the first section and the second section are connected together by an interference fit, a press fit, a friction fit, and/or a transition fit. 
     
     
         4 . An article as claimed in  claim 1 , not comprising a dedicated sealing element for inhibiting or preventing capillary flow of an aerosolizable material from the reservoir through the capillary channel. 
     
     
         5 . An article as claimed in  claim 1 , wherein at least one of the opposing surfaces comprises more than one surface feature for preventing capillary flow of an aerosolizable material from the reservoir through the capillary channel. 
     
     
         6 . An article as claimed in  claim 1 , wherein at least one surface feature extends continuously around its respective opposing surface such that aerosolizable material cannot flow from the reservoir through the capillary channel without being intercepted by the at least one surface feature. 
     
     
         7 . An article as claimed in  claim 1 , wherein the at least one surface feature is at least one groove. 
     
     
         8 . An article as claimed in  claim 7 , wherein the at least one groove has a width of at least 0.3 mm. 
     
     
         9 . An article as claimed in  claim 7 , wherein the at least one groove has a depth of at least 0.3 mm. 
     
     
         10 . An article as claimed in  claim 7 , wherein at least one groove is of a generally or substantially annular form. 
     
     
         11 . An article as claimed in  claim 7 , wherein at least one groove is substantially straight when viewed side-on. 
     
     
         12 . An article as claimed in  claim 7 , wherein at least one groove is substantially curved when viewed side-on. 
     
     
         13 . An article as claimed in  claim 7 , wherein at least one groove is of an undulating form when viewed side-on. 
     
     
         14 . An article as claimed in  claim 7 , wherein at least one groove forms a tortuous path when viewed side-on. 
     
     
         15 . An article as claimed in  claim 7 , wherein the at least one groove forms a zig-zag when viewed side-on. 
     
     
         16 . An article as claimed in  claim 1 , wherein the opposing surfaces have substantially the same hardness. 
     
     
         17 . An article as claimed in  claim 1 , wherein the opposing surfaces have a Shore A hardness of between 4 and 80. 
     
     
         18 . An article as claimed in  claim 1 , wherein the aerosolizable material is an aerosolizable liquid. 
     
     
         19 . A non-combustible aerosol provision system comprising:
 an article for use as part of the non-combustible aerosol provision system according to  claim 1 ; and   a device comprising one or more of a power source and a controller.   
     
     
         20 . A method of manufacturing an article according to  claim 1 , the method comprising:
 providing a housing having a first section and a second section; and   connecting the first section and the second section together to form a reservoir for an aerosolizable material, the first section and the second section being connected together to provide at least one pair of opposing surfaces;   wherein a capillary channel is provided between the opposing surfaces, and at least one of the opposing surfaces comprises at least one surface feature for inhibiting or preventing capillary flow of an aerosolizable material from the reservoir through the capillary channel.
