ABSTRACT:
A tobacco smoke filter includes a corrugated tape-like wrapping which, together with an outer perforated or otherwise air-permeable paper, defines a set of longitudinal grooves. Each of the grooves includes a blocking member, so as to inhibit direct smoke flow through the grooves and promote a ventilation effect. The blocking members in each groove are longitudinally staggered from one groove to the next to simplify the production of the device.
