ABSTRACT:
The cigarette mouthpiece is made of one-piece construction in which two semi-cylindrical shells are hinged together along one edge and are releaseably secured together at the free edges. The mouthpiece has an internal cylindrical smoke chamber which is separated from a tobacco column at one end by a baffle means while the opposite end of the smoke chamber is defined by a pair of abutting walls which are each slotted to define an orifice. The orifice is of a predetermined diameter less than the diameter of the smoke passage to control the amount of smoke flowing out of the smoke passage for a given draw. The exterior surface of the mouthpiece is provided with longitudinal grooves which cooperate with an overlying perforated tipping paper to define flow paths for ventilation air. For a given draw, an amount of undiluted unfiltered smoke is drawn from the tobacco column into the smoke chamber and through the outlet orifice. At the same time, a quantity of ventilation air is drawn in through the tipping paper and longitudinal grooves to envelop the undiluted smoke within a smoker's mouth.
