  • Patent number: 8100134
    Abstract: A cigarette includes a rod comprising a wrapped tobacco column that is joined to an axially aligned filter by a band of air impermeable tipping paper. The filter end of the rod is inserted into a mouthpiece having an air impermeable outer surface that comprises a ventilation tube and a second filter, separated by a mixing chamber. The ventilation tube has an air permeable annular wall that defines a central axial passage through which the rod extends. In use, the end surface of the annular wall at the rod end of the ventilation tube, which extends radially outward around the rod, acts as a ventilation surface through which air is drawn into the mixing chamber, where it mixes with mainstream smoke from the burning tobacco rod. The air/smoke mixture is drawn through the second filter into the consumer's mouth.

  • Publication number: 20120006344
    Abstract: A smoking article provides one or more sheets of material that can be rolled and packaged, at least one sheet including cellulose. In one embodiment, cellulose and tobacco sheet material are separately rolled layers that can optionally be wrapped around a form casing (or pre-rolled inside) and then packaged. In another embodiment, the sheet is a laminated sheet of tobacco and cellulose layers that can be optionally wrapped around (or pre-rolled inside) a form casing. These sheets can be filled with custom tobacco to make one or more new cigars for an end user. In another embodiment, a complete cigar filled with tobacco material can be disassembled by an end user to produce tobacco and cellulose sheets, enabling the end user to form two new cigars using his or her own custom tobacco.

  • Publication number: 20110305888
    Abstract: A recycling program provides a monetary incentive to encourage recycling of target waste materials, such as paper, glass and plastic products. A precious metal, such as gold, silver, platinum or palladium, is incorporated into the target waste material during manufacturing to provide an incentive for recycling the target material. A visual marking is placed on the target material to distinguish from other waste items that do not contain a precious metal. A deposit is collected from consumers when purchasing the target material, and the deposit is paid back when the target material is delivered to a recycling collection point. Recycling of the target material is encouraged by efforts to reclaim the precious metal.

    Abstract: A cigarette includes lighting and mouth ends. It may include a smokable segment disposed at the lighting end. It also includes a mouth-end segment; an aerosol-generation system disposed between the lighting and mouth ends, which includes (i) a heat-generation segment adjacent the smokable segment, including a heat source configured to be activated by combustion of a smokable material and an insulation layer of a non-glass material that is woven, knit, or both, and (ii) an aerosol-generating segment with aerosol-forming material disposed between, but physically separate from, each of the heat generation segment and the mouth end; a piece of outer wrapping material that provides an overwrap around at least a portion of the aerosol-generating segment, the heat-generation segment, and at least a portion of the smokable segment; those segments being connected together by the overwrap to provide a cigarette rod; that is connected to the cigarette rod using tipping material.

  • Patent number: 7987856
    Abstract: A smoking article having a tobacco rod of a smokable material and a filter system attached to the tobacco rod of smokable material. The filter system includes a first filter portion and a second filter portion, the second filter portion concentrically positioned with respect to the first filter portion and having a lower resistance to draw than the first filter portion during an initial puff on the smoking article. The second filter portion closes upon contact with the mainstream smoke of the initial puff, such that after the initial puff, the first filter portion has the lower resistance to draw.
