  • Patent number: 10820625
    Abstract: A smoking article comprises a tobacco rod and a filter connected to the tobacco rod. The filter comprises a first filter segment and a hollow tube segment downstream of the first filter segment. The hollow tube segment defines a cavity at the mouth end of the filter providing an unrestricted flow channel that extends from the downstream end of the first filter segment to the mouth end of the filter. The length of the hollow tube segment is at least about (25) percent and less than about (50) percent of the overall filter length. Further, the smoking article comprises a ventilation zone in communication with the cavity at a location along the hollow tube segment.

  • Patent number: 10609955
    Abstract: The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.

  • Patent number: 9307788
    Abstract: A filtered cigarette possesses a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The cigarette possesses more than one layer of tipping material. An outer layer of tipping material can overlie at least a portion of an underlying inner layer of tipping material, and during use by the smoker, the outer layer can be removed from the cigarette. Thus, it is possible for a cigarette manufacturer to provide a cigarette that can be used as such by the smoker, or that can be adapted by the smoker to provide a different sensory experience (e.g., the visual, organoleptic, trigeminal, aromatic, and tactile characteristics of the cigarette can be altered by removal of the outer tipping material). Alternatively, the use of the outer layer of tipping material can be used to improve the physical integrity of the cigarette.

    Abstract: A smoking article (10, 30, 40, 50, 70) with variable ventilation comprises a mouthpiece (12) circumscribed by a first wrapper (24) and a second wrapper (25). The first wrapper (24) and the second wrapper (25) are substantially air impermeable and are movable relative to one another between a low ventilation configuration and a high ventilation configuration. The mouthpiece (12) comprises a first airflow pathway (18, 19) through the first wrapper (24) or the second wrapper (25) and a second airflow pathway (26) through the first wrapper (24) or the second wrapper (25). In the low ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) is restricted and airflow into the mouthpiece (12) through the second airflow pathway (26) is substantially unrestricted. In the high ventilation configuration airflow into the mouthpiece (12) through the first airflow pathway (18, 19) and the second airflow pathway (26) is substantially unrestricted.

  • Patent number: 8863757
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.

  • Patent number: 8770206
    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.
