Abstract:
A smoking article such as a filter cigarette includes a rotary flow control device (2) in its filter assembly that comprises first, second and third body portions (3, 4, 5). The first body portion (1) contains a plug (6) of filter material and is attached to a tobacco rod (1). The second portion (4) contains different smoke flavorants in different sectors (18), which can be aligned by manual rotation individually with a smoke flow passageway (13, 35) to impart different flavors to the smoke that passes to the mouth of the consumer. The second body portion (4) is rotated through the agency of the third body portion (5). First and second ratchet mechanisms (14,19; 20, 24) are disposed between the second body portion (4) and the first and third body portions respectively to allow assured rotation of the second portion to select individual flavorants for the smoke passing to the consumer.
