20100186757 | Smoking Article - A smoking article, such as a cigarette, comprises a lighting end and a mouth end. The smoking article possesses an aerosol-generation system that includes (i) a heat generation segment, and (ii) an aerosol-generating region or segment. A mouth end piece segment can be located at the mouth end of the smoking article. A segment of tobacco cut filler, gathered tobacco paper, or other type of flavor source material, can be positioned between the mouth end piece segment and the aerosol-generation segment. Optionally, segment composed of tobacco cut filler can be positioned so as to provide a lighting end segment. The smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the mouth end piece segment, the aerosol generation segment, at least a portion of the length of the heat generation segment, any segment located between the mouth end piece and aerosol generation segments, and at least a portion of the length of the optional lighting end segment. Alternatively, the smoking article possesses an overwrap (e.g., a single paper overwrap) that extends over the longitudinally extending surface of the aerosol-generating segment, at least a portion of the length of the heat generation segment, at least a portion of any segment located downstream from the aerosol-generating segment, and at least a portion of the length of the optional lighting end segment, thereby forming a cigarette rod; and the cigarette rod is connected or attached to a filter element using a tipping type of material and arrangement. | 07-29-2010 |
20120227754 | SMOKING ARTICLES AND WRAPPING MATERIALS THEREFOR - A smoking article includes a smokable rod manufactured using a paper wrapping material having an additive material applied thereto as a pattern. The additive material is applied as coating formulation (e.g., an aqueous coating formulation) incorporating a film-forming agent such as alginate, starch, or another polymer. The wrapping material includes at least one coated region with a porosity of less than about 20 CORESTA and a diffusion capacity no greater than about 0.2 cm/sec, where the coated region is on a base sheet with a porosity of greater than about 120 CORESTA and a diffusion capacity of at least 1.7 cm/sec. | 09-13-2012 |
20130167849 | METHOD OF TIPPING FOR SMOKING ARTICLE - A method is provided for manufacturing a smoking article from a wrapped tobacco rod and a filter material wrapped to form a filter plug. The method utilizes nozzle-applied cold glue adhesive rather than roller-applied adhesive applied to tipping material, which connects the tobacco rod to the filter plug. In other aspects, mechanisms for using the method are provided. | 07-04-2013 |
20130167851 | METHOD OF FILTER ASSEMBLY FOR SMOKING ARTICLE - A method is provided for manufacturing a filter of a filtered smoking article, where the filter material includes a fluid-releasing body. The method provides a fluid-resistant barrier between the filter material and plug wrap encompassing the filter material, where the barrier is applied as a hot melt adhesive. In other aspects, mechanisms for using the method are provided. | 07-04-2013 |
20130213421 | APPARATUS AND ASSOCIATED METHOD FOR FORMING A FILTER COMPONENT OF A SMOKING ARTICLE - Apparatuses, systems, and methods employing ultrasonic bonding to form filter elements for smoking articles are provided. Ultrasonic bonding can be employed to bond the fibers of filter material defining bloomed tow. Use of a plasticizer may not be necessary. Further, filter materials such as polylactic acid, which may not be bonded via a plasticizer, may be employed. However, triacetin or other additional components may be employed to provide the filter element with a desirable sensory attribute in some embodiments. Ultrasonic bonding may be conducted by an ultrasonic bonder that includes an anvil defining a pattern thereon that is selected to define a desired degree of bonding, and thereby a resulting desired firmness and/or pressure drop associated with the filter element. | 08-22-2013 |
20140305455 | SMOKING ARTICLES WITH NANOCELLULOSE BARRIER - A smoking article includes a lighting end longitudinally opposite a filter end that includes a filter. A fluid-releasing element is disposed longitudinally between the lighting end and filter end. A paper material circumscribes a portion of the smoking article, and a nanocellulose barrier disposed upon at least one surface or interface within the smoking article is provided, effective to control passage of fluid through the paper material. | 10-16-2014 |
20150059780 | CARBON CONDUCTIVE SUBSTRATE FOR ELECTRONIC SMOKING ARTICLE - The present disclosure provides components useful in heating, particularly heating of an aerosol precursor solution so as to vaporize the solution and form an aerosol. The disclosure particularly provides an electrically conductive, porous carbon heater. The heater may be combined with an aerosol precursor transport element that also is formed of carbon. The heater and transport element may form an atomizer that can be useful in an electronic smoking article, such as in a cartridge that is adapted for attachment to a control body. In some embodiments, the disclosure provides a cartridge of an electronic smoking article, the cartridge being formed substantially completely of carbon. | 03-05-2015 |
20150157052 | SMOKING ARTICLE AND ASSOCIATED MANUFACTURING METHOD - A method and apparatus for forming a smoking article are provided and involve engaging a heat generation segment and a tobacco rod segment with the wrapping material in a longitudinally spaced-apart relation, the outer wrapping material having a heat-conductive strip engaged therewith, and the heat generation segment and/or the tobacco rod segment at least partially overlapping one end of the heat-conductive strip. Lateral ends of the wrapping material are wrapped at most partially about the heat generation and tobacco rod segments such that the heat generation and tobacco rod segments cooperate with the heat-conductive strip to define a longitudinally-extending cavity accessible between the respective lateral ends of the wrapping material and heat-conductive strip. Aerosol generation elements are deposited into the longitudinally-extending cavity (i.e., by gravity feed) between the lateral ends of the heat-conductive strip, and the cavity is closed by overlapping and sealing the lateral ends of the wrapping material. | 06-11-2015 |
