  • Patent number: 8627826
    Abstract: Some embodiments of a tobacco article may include tobacco disposed in a porous matrix. The tobacco article may provide tobacco, tobacco constituents, or both tobacco and tobacco constituents to the consumer's mouth in the form of particles, liquid, or vapor so as to provide tobacco satisfaction to the consumer. In some circumstances, the tobacco may be integrally molded with a plastic material so that at least a portion of the tobacco is disposed in pores of the matrix.

  • Publication number: 20110100382
    Abstract: Oral tobacco products having a gel-coating and methods for making are provided. The method includes (a) molding a portion of tobacco material to form a pre-portioned piece of tobacco material, the tobacco material comprising moist smokeless tobacco; (b) contacting the pre-portioned piece of tobacco material with a gel-coating solution to form a gel-coating comprising at least one polymer on an outer surface of the pre-portioned piece of tobacco material to form a gel-coated oral tobacco product, said gel-coating comprising an inner surface disposed around the pre-portioned piece of tobacco material and an outer surface; and (c) forming one or more of perforations, uncoated areas and holes in the gel-coating of the oral tobacco product to form a gel-coated oral tobacco product.

  • Patent number: 7836897
    Abstract: The lighting end or tip of the smoking article is configured in such a manner that the entire front or upstream face thereof does not lie in a plane that is generally perpendicular to the longitudinal axis of the smoking article. For example, at least a portion of the front face of the smoking article lies in a plane (e.g., a generally flat plane) that is positioned about 40° to about 50° relative to the longitudinal axis of that smoking article. As such, the overall nature or character of the mainstream aerosol generated by a smoking article can be altered. This shape may include an ellipse, or may include a first section in a plane not perpendicular to the longitudinal axis and a second section in a plane perpendicular to the longitudinal axis. Alternatively, the face of the lighting end may have a shape such that its surface area is greater than the cross-sectional area of the smoking article.

  • Patent number: 6162516
    Abstract: The present invention involves a system and method for a user of smokeless tobacco to reduce the deleterious effects to oral tissues from the chemicals generated from using smokeless tobacco. A protective shield encloses a quantity of tobacco while resting in a mouth of a user, generally between the cheek and gum surfaces. The protective shield may be impermeable, sanitary, and disposable or biodegradable. It may assist in reducing leukoplakia and other oral diseases related to the use of smokeless tobacco. It attempts to allow the normal use of smokeless tobacco without interfering with speech, drinking, and other activities while providing some protection from the chemicals. The present invention involves a system and includes a container for holding the shields, having an opening for removing the shields for convenience and to encourage use, typically in the vicinity to a quantity of smokeless tobacco for easy access.

  • Patent number: 5346734
    Abstract: An oral pouch that is constructed of an orally safe natural rubber material that can be packed with any brand or flavor of loose moist snuff, by the individual user. The pouch is sized using scissors for maximum comfort and fit, and once inserted between the lower gum and lip, serves as a barrier between the tobacco product and the lip and gum area, therefore reducing the direct physical contact of the tobacco product against the gum and lip. Because the pouch is perforated, saliva flows through the pouch moistening the tobacco, creating the tobacco juice.

  • Patent number: 4391285
    Abstract: Smoking articles comprising a high density, relatively low porosity coherent mass of combustible tobacco-containing material having at least one passage extending therethrough are disclosed. In a preferred embodiment the smoking article is a cylinder having at least one passage axially therethrough. The smoking article may further comprise a plug of ignitable material in passage blocking position at one end of the passage, said plug being such as to permit puff induced air flow therethrough. At least one additional plug may be similarly disposed at the opposite end of the passage or at an intermediate point in the passage. By adjusting the density, the surface area and/or the porosity of the mass available for combustion, the per puff delivery of tar by the smoking article upon combustion may be controlled.
