Abstract
The invention concerns a smoking article filter plug (16) for a cigarette, the filter plug being cylindrical and having a plug wrap (18), grooves (20) being impressed into the plug wrap, and a tipping paper (22) for the attachment of the filter plug to the tobacco rod (12). Some grooves are axially extending with respect to the axis of the filter plug and are open on the side of the tobacco rod and extend continuously only over a part of the length of the filter plug. All grooves are covered by a ventilated tipping paper, which allows ventilating air into the axially extending grooves only. In addition, the invention concerns the use of such a filter for the reduction of the CO/tar ratio as a function of the filter ventilation.
