Abstract (en)

[origin: EP0025327A1] The flow of filtered, diluted smoke from a cigaret mouthpiece is given improved sensory effect by concentrating it into a narrow, collimated, preferably centralized pattern. This can be achieved by fitting the filter 12 of the cigaret with a mouthpiece 13 having a restricted channel opening at an orifice 14 of smaller cross sectional area than the filter. The effect is most useful with cigarets having relatively low delivery of particulate matter.
