Abstract

The cigarette filter plug has a body of entrainment-type fibrous filter material. Alayer of plug wrap paper of pre-determined thickness is circumferentially wrapped about the body. A peripheral annular groove of a depth at least equal to the thickness of the layer of plug wrap paper, extends through the layer of plug wrap paper to communicate the exterior of the filter plug with the body of filter material. Pref. the groove is of a depthgreater than the thickness of the layer of plug wrap paper and penetrates into the body of filter material to give a filter plug for a high air dilution cigarette.
