Aerosol provision device

Abstract

An aerosol provision device has a body defining an air flow passage through the body and an opening at one end of the air flow passage. An outer cover covers the opening, and a threaded engagement is provided between the outer cover and the body. An airflow path is defined through at least one of the outer cover and the threaded connection and arranged to allow airflow across the outer cover.

         13 . An aerosol provision system comprising an aerosol provision device of  claim 1 , and an article containing aerosol generating material arranged to be at least partially received in the aerosol provision device. 
     
     
         14 . An outer cover for covering an opening of an air passage in a body of an aerosol provision device, comprising:
 a cover member;   a thread arrangement on the cover member arranged to threadingly engage with the body; and   an airflow path defined through at least one of the cover member and the thread configuration arranged to allow airflow across the cover member.   
     
     
         15 . An outer cover for covering an opening of an air passage in a body of an aerosol provision device, comprising:
 a cover member;   a tool receiving recess configured to receive a tool to aid disengagement of the cover member from the body of the aerosol provision device; and   an airflow path defined across the cover member, wherein the tool receiving recess defines at least part of the airflow path.   
     
     
         16 . The outer cover of  claim 15 , wherein the cover member comprises a first side and a second side, and wherein the tool receiving recess comprises a tool slot on the first side of the cover member. 
     
     
         17 . (canceled) 
     
     
         18 . The outer cover of  claim 15 , wherein the cover member comprises a thread for threadingly engaging with the body of the device. 
     
     
         19 . The outer cover of  claim 15 , wherein the cover member is separable from the body. 
     
     
         20 . (canceled) 
     
     
         21 . (canceled) 
     
     
         22 . (canceled) 
     
     
         23 . An aerosol provision device, comprising:
 a body defining an air flow passage through the body and an opening at one end of the air flow passage,   an outer cover for covering the opening according to  claim 15 .   
     
     
         24 . An aerosol provision system comprising the aerosol provision device according to  claim 23 ; and
 a tool configured to engage with the tool receiving recess.   
     
     
         25 . An aerosol provision device, comprising:
 a body defining an airflow passage through the body and an opening at one end of the air flow passage;   an outer cover for covering the opening;   the body defining a cavity on an outer side of the body arranged to at least partially receive the outer cover, the cavity comprising a base surface and a peripheral wall; and   wherein an airflow path is defined between the base surface and the outer cover.
