  • the aerosolgenerating material is again disturbed and tends to become displaced and move relative to the wrapper.
  • the first portion 9a of the end plug 9 at least partially covers the end face 8 of the aerosol-generating section and so prevents the aerosol-generating material from falling out of the article 1, particularly when the pin heater 9a is withdrawn from the aerosol-generating section 4. This improves the overall hygiene of the system because pieces (e.g. particles or flakes) of aerosol-generating material are prevented from leaving the article and entering other components of the system, such as the aerosol provision device.
