Assembly for insertion into an aerosol provision device

Abstract

An assembly (400) for insertion into an aerosol provision device (100) is provided. The assembly comprises a body (402), aerosol forming material positioned along a flow path at least partially defined by the body, and a sealing element (404). The sealing element is moveable between a first position (FIG. 4A) and a second position (FIG. 4B). In the first position the sealing element is configured to close at least a portion of the flow path to reduce atmospheric air contacting the aerosol forming material. In the second position the sealing element is positioned to allow atmospheric air to travel along the flow path and contact the aerosol forming material. The sealing element is attached to the body in both the first position and the second position.
