Abstract

A cartridge for an aerosol provision device comprises a chamber for containing a liquid from which a flow of aerosol for inhalation by a user is generated. The cartridge comprises a first connector arrangement for releasably connecting the cartridge to a body portion of the device, and a second connector arrangement for releasably connecting to a container for a material. In use, aerosol flows through the material in the container before being inhaled by the user. The first connector arrangement is configurable in a locked configuration and in an un-locked configuration, and the first connector arrangement must be configured in the un-locked configuration for the cartridge to be removeable from the body portion. The first connector arrangement is configurable from the locked configuration to the un-locked configuration while the cartridge remains stationary with respect to the body portion.

         8 . A cartridge according to any of  claims 1  to  7  wherein the first connector arrangement is located at a distal end of the cartridge and the second connector arrangement is located at a proximal end of the cartridge and the cartridge is tapered from the distal end to the proximal end such that the cross-sectional area of the proximal end is less than the cross-sectional area of the distal end. 
     
     
         9 . A cartridge according to any of  claims 1  to  8  wherein the second connector arrangement allows the container to be attached to/detached from the cartridge by pushing/pulling the container and the cartridge together/apart. 
     
     
         10 . A cartridge according to any of  claims 1  to  9  wherein the second connector arrangement comprises a recess in the cartridge into which the container for a material is inserted. 
     
     
         11 . A cartridge according to  claim 10  wherein the container comprises at least one first surface formation which interfaces with an interior surface of the recess of the cartridge. 
     
     
         12 . A cartridge according to  claim 10  or  claim 11  wherein the recess comprises an interior surface comprising at least one second surface formation which interfaces with the container. 
     
     
         13 . A cartridge according to  claim 11  or  claim 12  wherein the container comprises at least two first surface formations which interact with an interior surface of the recess of the cartridge. 
     
     
         14 . A cartridge according to  claim 13  wherein the container comprises at least three first surface formations which interact with an interior surface of the recess of the cartridge. 
     
     
         15 . A cartridge according to any of  claims 11  to  14  wherein at least one of the at least one first surface formations is a first ridge and at least one of the at least one second surface formations is a corresponding first groove and the first ridge interacts with the corresponding first groove to hold the container in the recess and provide a substantially airtight seal. 
     
     
         16 . A cartridge according to any of  claims 11  to  15  wherein at least one of the at least one second surface formations is a second ridge and at least one of the at least one first surface formations is a corresponding second groove and the second ridge interacts with the corresponding second groove to hold the container in the recess and provide a substantially airtight seal. 
     
     
         17 . A cartridge according to any of  claims 1  to  16  wherein the container is part of a mouthpiece assembly, and wherein the mouthpiece assembly comprises:
