20100031967 | SMOKING ARTICLE - A smoking article includes a monitor monitoring a smoke delivery from a cigarette or a physical quantity correlated with the smoke delivery, a regulating mechanism regulating the smoke delivery, and a control unit controlling the regulating mechanism depending on the smoke delivery. | 02-11-2010 |
20100108084 | FILTERED CIGARETTE WITH DIFFUSE TIPPING MATERIAL - A filtered cigarette includes a smokable rod and a filter element. The smokable rod is secured to the filter element using tipping material. The tipping material includes at least one flavorant providing a sensory characteristic. The cigarette may include 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, and or by provision of a tipping material layer that is treated with a flavorant and/or provides a desirable diffusivity). The use of the outer layer of tipping material can be used to improve the physical integrity of the cigarette. | 05-06-2010 |
20100163065 | Connectable Cigarette Filter - A connectable cigarette filter comprises a mouthpiece and a plurality of, or one to two, or two to three filter units connected with the mouthpiece. The mouthpiece is an inclined cylindrical body centrally provided with a stepped aperture. The stepped aperture has a front section formed as a sloped cavity. The inclined cylindrical body has a rear section whose outer surface is provided with a pair of planes. The filter unit is a stepped cylindrical body with a stepped through-hole comprising a large-diameter through-hole and a small-diameter through-hole. The front section of the stepped through-hole is formed as a sloped counterbore. The stepped cylindrical body has a rear section formed as a small-diameter, sloped cylindrical body which is shaped and sized according to the sloped counterbore, so that the small-diameter, sloped cylindrical body of one filter unit is insertable into the sloped counterbore of another filter unit. | 07-01-2010 |
20100288293 | SMOKING ARTICLE WITH IMPROVED FLOW RESTRICTION ELEMENT - A smoking article includes a rod of smokable material and a filter including a flow restriction element attached to the rod of smokable material. The flow restriction element includes a first upstream integral tubular portion, a second downstream integral tubular portion of substantially the same external diameter as the first tubular portion, and a third central integral tubular portion located between the first and second tubular portions. The third tubular portion is of reduced external diameter compared to the first and second tubular portions. A transverse barrier having at least one orifice therein is disposed between a first upstream cavity at least partially defined by an inner periphery of the first tubular portion and a second downstream cavity at least partially defined by an inner periphery of the second tubular portion. A ventilation zone in communication with the second cavity is also provided at a location along the filter. | 11-18-2010 |

20110232663 | FILTER CIGARETTE WITH VARIABLE VENTILATION - A filter cigarette with variable ventilation includes a rod of smokable material, a mouthpiece including an element rotatable relative to the rest of filter cigarette about the longitudinal axis thereof to vary the ventilation of the filter cigarette, and a ventilation indicator including a scale extending circumferentially about the periphery of the filter cigarette and a cursor. The scale is symmetric about the longitudinal axis of the filter cigarette and the cursor and the scale are rotatable relative to one another about the longitudinal axis of the filter cigarette. One of the cursor and the scale rotate with the rotatable element of the mouthpiece, the level of ventilation being indicated by the longitudinal distance between the cursor and a longitudinally aligned point on the scale. | 09-29-2011 |
20120000482 | FILTER DESIGN FOR IMPROVING SENSORY PROFILE OF CARBON FILTER-TIPPED SMOKING ARTICLES - A filter for a smoking article, which includes an upstream segment having a carbon filter and a downstream segment of filtering material. The upstream segment includes a carbon filter with a hollow tubular member concentrically positioned within the carbon filter, and one or more holes around an outer circumference of the hollow tubular member to allow mainstream smoke to bypass the carbon filter during the first puff. During use, the hollow tubular member has a lower resistance to draw than the carbon filter during an initial puff or puffs, and after the initial puff or puffs, mainstream smoke is drawn through the carbon filter. | 01-05-2012 |
