Cigarette with wrapper having additive package
First Claim
1. A cigarette comprising a rod of smokable material contained in a circumscribing paper wrapping material in intimate contact with an additive package, the paper wrapping material comprising a cellulosic base web and an additive package including water soluble components, which additive package(a) provides about 5 to about 40 percent of that paper wrapping material on a dry weight basis;
- and(b) includes (i) alkali metal ions and (ii) alkali earth metal ions, such that the ratio of equivalents of (i) to (ii) ranges from about 0.05 to about 1; and
(iii) inorganic anions and (iv) organic anions, such that the ratio of equivalents of (iii) to (iv) ranges from about 0.05 to about 0.7;
the equivalents of components (i) plus (ii) being equal to the equivalents of components (iii) plus (iv).

Abstract
A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by at least one layer of paper wrapping material to form a tobacco rod. A certain cigarette includes an outer wrapping material which circumscribes and overwraps an inner wrapping material. At least one paper wrapping material of the tobacco rod includes an additive package. The additive package includes at least one water soluble salt which is applied in a water soluble form. For example, a paper wrapper including wood pulp fiber and calcium carbonate filler material is treated with an aqueous solution of calcium acetate, potassium chloride and potassium acetate. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.
