Description

PRIORITY CLAIM The present application is a National Phase entry of PCT Application No. PCT/GB2020/051868, filed Aug. 5, 2020, which claims priority from Great Britain Application No. 2000237.4, filed Jan. 8, 2020, each of which is hereby fully incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to aerosol provision cartridges, and systems and methods relating thereto. BACKGROUND Aerosol provision systems such as e-cigarettes generally contain, amongst other parts, an aerosol provision cartridge which comprises a reservoir of an aerosol precursor material, such as a source liquid or aerosolizable material, typically including nicotine, from which an aerosol is generated, e.g., through vaporization or other means. The aerosol provision cartridge may also comprise an aerosol generating component, such as a heater, which is fluidly connected to the aerosol precursor material contained in the reservoir. When a user inhales on the device, the aerosol generating component is activated to vaporize an amount of the aerosol precursor material. More particularly, such devices are usually provided with one or more air inlet holes located away from a mouthpiece of the system. When a user sucks on the mouthpiece, air is drawn in through the inlet holes and past the aerosol generating component. There is a flow path connecting between the aerosol generating component and an opening in the mouthpiece so that air drawn past the aerosol generating component continues along the flow path to the mouthpiece opening, carrying some of the aerosol produced from the aerosol generating component with it. The aerosol-carrying air exits the aerosol provision system through the mouthpiece opening for inhalation by the user. Typical aerosol generating components comprise a heater. The aerosol precursor material is generally arranged within the system such that it can access the aerosol generating component. For example, it may be that the aerosol generating component is a wire which is heated during use of the device. As a result of the contact between the aerosol precursor material and the wire, when the wire is heated during use the aerosol precursor material is vaporized and subsequently condenses into an aerosol which is then inhaled by the user. The means by which the aerosol precursor material can contact the wire may vary. It is not uncommon for the aerosol precursor material to be held freely in a refillable tank or other refillable storage region, and then directly fed to the heating wire (which may itself include a wick to assist in holding the aerosol precursor material in proximity to the wire). To inhibit leakage of aerosol precursor material from such a refillable tank or storage region, and also to inhibit inadvertent access to such aerosol precursor material-holding regions by the user, it would be desirable to provide an aerosol provision system/cartridge which is configured accordingly.
