Flavour liquid introduced into the cavity-comprisingsheet portion 44 is absorbed by theabsorbent material 70 which will subsequently transfer to the tobacco-containingsubstrate 120 by simple diffusion for example, through the micro-perforations 66 on the pouch. - The
absorbent material 70 according to the present invention behaves like a sponge which is capable of absorb the flavour liquid, either provided directed by a user or the liquid is being released from a capsule. Once the flavour liquid is being absorbed, the flavour can be slowly released through the micro-perforations to reach the tobacco-containing substrate, thereby the entire content of the open tobacco compartment is flavoured evenly and effortlessly.
