ABSTRACT:
A cigarette with a tobacco rod (5,6) has at its buccal end a filter plug (10) and a hollow tubular core (8) with a cross wall (9) formed with orifices of a certain size and shape. Ventilating air drawn in through perforations (12) in a tipping wrapper (7) and through a porous inner wrapper (11) is mixed with smoke drawn through the tobacco rod and the mixture is sucked through the orifices (13) which promote particular mixing and pressure drop effects.
