  • Smoking article with improved insulating material
    Patent number: 5303720
    Abstract: The present invention relates to an improved insulating sheet material and to cigarettes and other smoking articles which employ the insulating sheet material as one or more components thereof. The improved insulating material is particularly useful in smoking articles having a fuel element and a physically separate aerosol generating means, e.g. as an insulating member for insulating the fuel element. In general, the sheet material of the present invention is formable without the use of any organic binder and comprises an inorganic fibrous material such as calcium sulfate fibers, calcium sodium phosphate fibers, or mixtures thereof, and a relatively small amount of highly refined cellulose-based fibers such as wood pulp.

    Abstract: Cigarettes include tobacco-containing smokable material wrapped in a low porosity paper wrapper.
