SMOKING ARTICLE Russian patent published in 1999 - IPC

FIELD: cigarette industry. SUBSTANCE: smoking article has tobacco core enclosed in separate jacket made from cigarette paper and elongated flexible tip of size corresponding to that of cigarette (with length of tubular part of at least 40 mm being taken as cigarette size of tip) and joined to tobacco core. Tip is manufactured from compressed fibrous material and is provided with filtering member made from the same fibrous material and positioned at side adjacent to tobacco core. Filtering member is formed as continuous cylinder of diameter equal to that of tip tubular part. Total length of tip exceeds length of tobacco core. Cylindrical filtering member has length at least half the length of tubular part of tip. Tobacco core is connected to tip by paper rim at least partially overlapping surface of cylindrical filtering member. Fibrous material of tip is compressed so that it resumes effective section of tubular part upon release of compressive force which had been applied for complete compression of tubular part. Cylindrical filtering member is made integral with tip and from the same fibrous material for eliminating the possibility for smoke to exit into tip without filtering cycle and for preventing tobacco chips from getting into tip. EFFECT: increased efficiency and improved quality of smoking article by enhanced smoke filtering capacity. 9 cl, 6 dwg
