Abstract
A smoking article, such as a cigarette, has a mouth section which includes a generally cylindrical, impermeable, plug member located in coaxial abutment to one end of the tobacco column of the cigarette. A plurality of smoke flow capillaries are formed through the plug member. A generally hollow cylindrical tubular mouthpiece having a plurality of grooves are formed in the periphery of the mouth section extending generally longitudinally thereof is located in coaxial abutment to the end of the plug member. Air permeable tipping material circumferentially surrounds the mouth section and overlaps a portion of the tobacco column adjacent the mouth section to fasten the mouth section to the tobacco column. In a further embodiment of the present invention, the mouth section includes the generally cylindrical impermeable plug located in coaxial abutment to one end of the tobacco column formed with a plurality of generally longitudinally extending grooves in the peripheral surface in addition to having smoke flow capillaries therethrough. A generally cylindrical, tubular mouthpiece is located in coaxial abutment to the end of the plug member. Air permeable tipping material circumscribes the mouth section and overlaps a portion of the tobacco column adjacent the mouth section to fasten the mouth section to the tobacco column.
