Abstract

A ventilated smoker's mouthpiece, e.g. for a cigarette, in which the degree of ventilation is readily adjustable. The mouthpiece includes a ventilating outer sleeve around a buccal end core member and an adjacent upstream core member longitudinally aligned therewith. The buccal end core member bus, extending upstream from its exposed end, a portion which is movable longitudinally relative to the remainder thereof to move the adjacent upstream core member longitudinally relative to the sleeve to vary the extent of ventilation permitted through the outer sleeve. Thus, the outer sleeve may have one or more ventilating orifices, with longitudinal movement of the adjacent upstream core member under the action of the movable portion of the buccal end core member, bringing the upstream core member at least partially into or out of blocking registration with the ventilation orifice or orifices, or altering the extent of such blocking registration, with the amount of ventilation permitted varying accordingly.
