A plurality of weakness formations (150) are provided on a region of the wrapper overlying the com- bustible heat source. The wrapper is rupturable during use at the plurality of weakness formations to form a ventilation zone comprising a plurality of apertures ex- tending through the wrapper. The weakness formations may be arranged such that the wrapper ruptures at the X X X X weakness formations under the pressure generated by combustion gases from the combustible heat source dur- XXXXX ing use.
