The present invention provides a tobacco smoke filter or filter element having a longitudinally extending core (,) and a wrapper (,) engaged around the core (,), the wrapper (,) having particulate additive (,) adhered to one or more portion(s) of the radially inner face thereof with said wrapper (,) being free of additive around its circumference at one or both ends of the core.

Tobacco smoke filter

A smoke filter consists of substrate threads and/or strips each pre-coated with particulate sorbent (e.g. activated carbon granules), gathered together in solid or tubular rod form e.g. within a containing sleeve. When the gathered threads and/or strips form a tubular body, this may be provided with a core.

Particulate sorbent smoke filter

Concentric core filter

A filter having a longitudinal axis and having a tube formed by at least one strip [2] which is pre-coated with particulate smoke modifying additive [4] adhering thereto and which curves through at least 360.degree. about the longitudinal axis.

Smoke filter containing particulate smoke modifying additive

A tobacco smoke filter comprising a rod of tobacco smoke filtering material incorporating particulate additive, wherein at least some of the particulate additive is concentrated on one or a restricted number of threads and/or strips incorporated within the remaining body of filtering material, the additive adhering to said thread(s) and/or strip(s).

Tobacco smoke filter containing particulate additive

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.
