  • Patent number: 8852350
    Abstract: A smoking article, and a method and apparatus for producing a smoking article, in which a web material containing an adsorbent material such as activated carbon and a stabilized flavorant such as menthol is positioned adjacent an interior surface of a cigarette wrapper to deliver flavor to a smoker with minimal/insignificant migration of flavor to other parts of the smoking article or packaging. The web material may be a section that extends over only a portion of the smoking article to deliver flavor to a smoker at a specific point during smoking and if positioned at the mouth end of a smoking article will be able to deliver a flavor sensation in the final puff(s).

  • Patent number: 8807144
    Abstract: 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.

  • Patent number: 8783266
    Abstract: A tobacco product is formed by rolling moistened tobacco leaves about a cylindrical form casing and allowing the leaves to dry to form a shell. After the form casing is removed a consumer can fill the shell with crushed tobacco leaves of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product.
