ABSTRACT:
A mouthpiece for a filter-tipped smoking product or a filtered cigarette holder which has an inlet end adjacent the mouth end of the filter and an outlet end opposite the inlet end through which smoke may leave the cigarette or cigarette holder for passage into the mouth of the smoker. The outlet end has at least one orifice therein and the orifice is of smaller area in transverse section than the filter. The inlet end is of substantially the same transverse area as the filter and is connected to the orifice by a continuous channel which continuously decreases in transverse sectional area from the inlet end to a point between the inlet end and the outlet end and from which point to the orifice is either the same or continuously increasing until it is the same transverse sectional area as the orifice. Smoke exiting the filter passes into the channel at the inlet end of the mouthpiece, passes exclusively through the channel and exits through the orifice in a narrow pattern.
