Arthur M. Ihrig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7836898
    Abstract: A smoking article having reduced ignition propensity is disclosed. The smoking article includes a tobacco column, a wrapper surrounding the tobacco column and a filter element. The wrapper has a base permeability, an untreated area and a least one discrete area treated with a composition to reducing the base permeability. The discretely treated area interacts with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated area includes a permeability reducing substance, a burn rate retarding substance and a burn rate accelerating substance. Either the burn rate retarding substance or the burn rate accelerating substance acts as an organoleptic enhancing substance. In this way a smoker's experience when smoking either the at least one treated area or the untreated area is substantially the same.

  • Publication number: 20040123874
    Abstract: A smoking article having reduced ignition propensity is disclosed. The smoking article includes a tobacco column, a wrapper surrounding the tobacco column and a filter element. The wrapper has a base permeability, an untreated area and a least one discrete area treated with a composition to reduce the base permeability. The treated area is treated with a composition initially comprising a permeability reducing substance initially dissolved in a non-derivatizing solvent mixture initially comprising a solvent component and at least one ingredient that as part of the solvent mixture is a self-association disrupter for the permeability reducing substance. The discretely treated area interacts with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated area includes a permeability reducing substance.

  • Patent number: 4452259
    Abstract: This invention relates to smoking articles having reduced free burn time, including cigarettes, cigars and little cigars. The smoking article comprises tobacco wrapped in a paper having at least one circumferential band printed between the ends of the smoking article; preferably at about the center of the smoking article. The band contains a substance which will cause the smoking article to extinguish in about 2-5 minutes under free burn conditions after the cone reaches the banded area if it is not puffed. The band is typically about 2-10 mm wide containing a substance which is a liquid in the temperature range of about 100.degree. C. to 200.degree. C. and which as the burning cone comes in contact with it provides a fluid film on the paper, without substantially penetrating through the surface of the paper, which film is substantially impervious to air and decomposes and/or distills endothermically from about 140.degree. C. to 300.degree. C.
