Abstract

See full text

A tobacco smoke filter is disclosed, which provides tobacco flavor enrichment of smoke passing therethrough. The filter comprises a reconstituted tobacco member formed from a coherent sheet of reconstituted tobacco which has been uniformly embossed with a series of parallel grooves, and then compacted and bonded into a self-sustaining dimensionally stable axially elongated body whose longitudinal axis extends parallel to the embossed grooves. The embossed grooves provide the reconstituted tobacco member with flow passages having a high surface area for contact with smoke passing therethrough, so as to enable the smoke to become tobacco flavor-enriched by extracing tobacco flavor from the reconstituted tobacco. The filter may also include an axially elongated fibrous filtering material member disposed concentrically with respect to the reconstituted tobacco member and having a draw resistance greater than that of the reconstituted tobacco member, whereby smoke passing through the filter will be directed primarily through the reconstituted tobacco member.
