|20130280320||Method For Producing Articles of Plant Origin Impregnated With a Liquid Plant Substance - The present invention relates to a method for producing articles impregnated with at least one plant substance from at least one plant, characterized in that it comprises the following steps:||10-24-2013|
|20120012124||Smoking Articles Having Reduced Carbon Monoxide Delivery - The present invention is directed to smoking articles having reduced carbon monoxide delivery are described. A carbon monoxide reducing agent is incorporated into the smoking article in order to reduce carbon monoxide levels in mainstream smoke. The carbon monoxide reducing agent may be, for instance, in metal oxide or in metal carbonate. The carbon monoxide reducing agent may be incorporated into a wrapper and/or into a column of smokable filler that are used to construct the smoking article.||01-19-2012|
|20110000497||Smoking Articles Having Reduced Analyte Levels and Process For Making Same - Smoking articles having reduced Hoffmann analytes contained in the mainstream smoke is disclosed. In one embodiment, an alginate composition is applied to a wrapper that is incorporated into a smoking article. The alginate composition causes a significant reduction in at least certain of the Hoffmann analytes that are generated when the smoking article is smoked. The alginate composition may be applied so as to cover a substantial portion of the surface area of the wrapper in one embodiment. In another embodiment, the alginate composition is applied as a single band to the paper wrapper so to cover a substantial portion of the distal end of the smoking article.||01-06-2011|
|20090120450||Smoking Articles Having Reduced Ignition Proclivity Characteristics - Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a paper wrapper containing cellulosic fibers and filler particles. The paper wrappers are treated with a film-forming composition in order to reduce the ignition proclivity characteristics of the smoking articles. In one embodiment, the film-forming composition contains an alginate combined with a starch. In an alternative embodiment, the film-forming composition contains a film-forming material combined with filler particles. The filler particles may comprise kaolin clay, magnesium oxide, mica, alum, or mixtures thereof.||05-14-2009|
|20080202542||Wrappers For Smoking Articles Having Reduced Diffusion Leading to Reduced Ignition Proclivity Characteristics - Smoking articles having reduced ignition proclivity characteristics are disclosed. The smoking articles include a wrapper comprising cellulosic fibers and a filler. In accordance with the present disclosure, the filler has a particle size of at least about 3.2 microns and is present in the wrapper in an amount less than about 20% by weight. Further, the wrapper may have a basis weight of less than about 23 gsm and a permeability of from about 15 Coresta to about 110 Coresta. It has been discovered that such wrappers are capable of reducing the ignition proclivity characteristics of a smoking article. If desired, the particular wrapper as described above can also contain discrete areas treated with an ignition reducing composition which further serves to reduce the ignition proclivity characteristics of the article.||08-28-2008|
