Abstract: The present invention provides a product and method of making thereof for the consumption of smokable substances such as tobacco or herbs. The product is comprised of tobacco, homogenized tobacco and/or natural leaf materials and has a hollow conical shape that allows for the easy insertion of smokable substances and further provides for larger amounts of smokable substances in the end of the product the consumer lights, resulting in an initial slower prolonged burn and more even distribution of nicotine. Additionally, the placement of a structure into one end of the hollow cone permits the consumer to consume the majority, if not all, of the smokable substance. This structure also prevents debris and other unwanted materials from being sucked through the end of the product and into the mouth and respiratory system of the consumer.

Abstract: A novel nanocatalyst is disclosed containing titanium oxide, iron oxide, and calcium oxide. The catalyst comprises a layer of iron oxide in the gamma form supported on a titanium oxide core. Addition of calcium cations helps to stabilize the iron oxide in the gamma form. The iron oxide layer is on the order of a few nanometers thick on the surface of the titanium oxide core, in an “egg-in-shell” structure. The nanocatalyst is highly active in promoting the oxidation of compounds such as hydroquinone, catechol, other hydrocarbons, chlorinated phenols, and carbon monoxide, even at moderately elevated temperatures. The catalyst remains active in a pyrolytic environment for extended periods of time, and possesses high redox cycling potential. The efficiency of the catalyst is not strongly affected by coking in a combustion environment.

Abstract: A zone or plug of porous adsorbent material, primarily activated carbon, is placed in the tobacco rod of a cigarette a short distance from the lighting end thereof. The amount of activated carbon is sufficient for effective removal of volatile smoke constituents while allowing the cigarette to burn continuously.

Abstract: Smoke constituent reduction is achieved by resolving from puff-to-puff analysis at which location along a tobacco rod production of a particular smoke constituent is maximized, and locally applying an attenuator at said resolved location to reduce production of the constituent. A remainder of the rod is left untreated so as to minimize impact on taste and burn characteristics of the cigarette. Reduction of the first puff formaldehyde formation is achieved by treating the cigarette tip with salts, using Burley tobacco in the tip, increasing the rod density, ventilation at the tip, and thermal treatment of the tip. Other classes of smoke constituents such as TSNAs (tobacco specific nitrosamines), PAHs (polycyclic aromatic hydrocarbons), etc., in particular the PAHs of naphthalene, phenanthrene, pyrene, flouranthene and benzo(a)pyrene may be reduced with placement of a carbon-based and/or metallic disc at the tip and with practices of the invention herein.

Abstract: A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls (e.g. moistened tobacco leaves) and/or homogenized sheet tobacco about a slit mandrel to form a shaped tube. The shaped tube is then packaged for shipment to an end user or consumer. The shaped tube remains in the rolled, shaped tube form inside the package. After the shaped tube is removed from the package, a consumer can fill the tube with crushed tobacco leaves or other tobacco filler material of a favorite blend, thereby eliminating some steps in the making of a “roll-your-own” tobacco product. A liquid can be added to the sheet or to the finished tube to moisturize same. The liquid can include flavoring. The tubes are unfilled when packaged and sent to a consumer/end user in tube form so that they have a “memory” that helps hold a tubular cigar shape after they are filled with selected tobacco fill material.
