Abstract

A filter cigarette comprising at least a bar of cellulose acetate or other suitable filter material surrounded by a layer which is impermeable to air, and between said both items a layer of a material with an open structure, of which layer a ring adjacent to the tobacco column is sealed, has better properties and is easier to produce than a filter cigarette having grooves in the impermeable layer and the bar of filter material.
