Aerosol provision system

Abstract

A system can include an aerosol provision cartridge; and a body to which the aerosol provision cartridge is attachable, wherein the cartridge comprises: a refillable chamber for aerosolizable material, the refillable chamber comprising an opening for insertion of aerosolizable material into the refillable chamber, an aerosol generating component comprising a heater, and closure means for preventing access to the opening, wherein the closure means is moveable from a first position in which access to the opening is prevented, and a second position in which access to the opening is possible, wherein the closure means is prevented by the body from moving to the second position when the aerosol provision cartridge is attached to the body, and wherein the closure means is covered by the body when the aerosol provision cartridge is attached to the housing; wherein the aerosol provision cartridge is attachable to the body by being inserted into a recessed end of the body, and wherein the closure means is configured to be covered inside the recessed end of the body when the aerosol provision cartridge is attached to the body.

1 . A system comprising:
 an aerosol provision cartridge; and   a body to which the aerosol provision cartridge is attachable, wherein the cartridge comprises:
 a refillable chamber for aerosolizable material, the refillable chamber comprising an opening for insertion of aerosolizable material into the refillable chamber, 
 an aerosol generating component comprising a heater, and 
 closure means for preventing access to the opening, wherein the closure means is moveable from a first position in which access to the opening is prevented, and a second position in which access to the opening is possible, wherein the closure means is prevented by the body from moving to the second position when the aerosol provision cartridge is attached to the body, and wherein the closure means is covered by the body when the aerosol provision cartridge is attached to the housing; 
   wherein the aerosol provision cartridge is attachable to the body by being inserted into a recessed end of the body, and wherein the closure means is configured to be covered inside the recessed end of the body when the aerosol provision cartridge is attached to the body.   
     
     
         2 . The system according to  claim 1 , wherein the aerosol provision cartridge further comprises an air outlet channel which extends from the aerosol generating component to an opening from the aerosol provision cartridge which is proximal a first end of the refillable chamber. 
     
     
         3 . The system according to  claim 2 , wherein the refillable chamber surrounds the air outlet channel. 
     
     
         4 . The system according to  claim 1 , wherein the aerosol provision cartridge further comprises a refill channel, wherein the opening is provided for allowing the aerosolizable material to be passed at pressure from outside the aerosol provision cartridge, through the first channel into the refillable chamber. 
     
     
         5 . The system according to  claim 1 , wherein the aerosol generating component is integral to the aerosol provision cartridge. 
     
     
         6 . The system according to  claim 1 , wherein when the aerosol provision cartridge is inserted into the recessed end of the body, electrical contacts located on the aerosol provision cartridge make contact with electrical contacts from the body to allow power from a battery located inside the body to be passed through to the aerosol provision cartridge. 
     
     
         7 . The system according to  claim 1 , wherein the aerosol generating component is located in the refillable chamber. 
     
     
         8 . The system according to  claim 1 , wherein the aerosol provision cartridge further comprises a mouthpiece, wherein the refillable chamber is at least partially located within the mouthpiece.
