Abstract

The sensory effect of cigarette smoke is improved by using a disc (24) to shape the flow of smoke (32) leaving smoking article (10) into a divergent pattern, thus increasing the perceived flavor of the cigarette. The effect is most useful with cigarettes having relatively low delivery of particulate matter.
