Claims
- 1. A wrapper for smoking articles, comprising a cellulosic sheet, inorganic filler in said sheet and a strong inorganic acid coated on at least the inner surface of the sheet.
- 2. The wrapper, as defined in claim 1, wherein the acid is selected from the group consisting of phosphoric, sulfuric, and hydrochloric acid.
- 3. The wrapper, as defined in claim 2, wherein the acid is applied at the size press with a burning chemical solution.
- 4. The wrapper, as defined in claim 3, wherein the acid concentration of the burning chemical solution is in the range of 0.01 to 2.0 molar.
- 5. The method, as defined in claim 1, further including adjusting the said solution to contain an acid concentration in the range of 0.01 to 2.0 molar.
- 6. A smoking article comprising a tobacco charge and a wrapper for the tobacco charge, said wrapper comprising a cellulosic sheet, inorganic fillers in said sheet and a strong, inorganic acid coated on at least the inner surface of the sheet.
- 7. The smoking article, as defined in claim 6, wherein the acid is selected from the group consisting of phosphoric, sulfuric and hydrochloric acid.
- 8. The smoking article, as defined in claim 7, wherein the acid is applied at the size press in a burning chemical solution.
- 9. The smoking article, as defined in claim 8, wherein the wrapper is treated with a burning chemical solution which contains an acid in the concentration range of 0.01 to 2.0 molar.
- 10. A method of improving the taste characteristics of smoking articles, the steps: forming a cellulosic sheet having inorganic fillers therein and coating a strong inorganic acid on at least the inner surface of the sheet, and wrapping the coated sheet about a tobacco column.
- 11. The method, as defined claim 10, wherein the inorganic acid is selected from the group consisting of phosphoric, sulfuric and hydrochloric acid.
- 12. The method, as defined in claim 11, adding the acid at the size press with a burning chemical solution.
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part of my application Ser. No. 07/514,533, filed Apr. 26, 1990.
Related subject matter is disclosed and claimed in my U.S. Pat. No(s). 5,065,777 and 5,107,864.
This invention relates to improved wrappers for smoking articles, to the method of making such wrappers and to smoking articles made from such wrappers.
The purpose of this invention is to impart improved subjective taste properties and sidestream aroma properties to cigarettes and other smoking articles. Smoking article wrappers of this invention have good appearance and high opacity, which, when fabricated into smoking articles with suitable tobacco columns and filter systems, statically burn at acceptable rates. Inorganic acid addition improves subjective taste properties and sidestream aroma properties with regular, heavy-weight, and low sidestream cigarette papers. The acid treatment can be used with:
Extensive subjective taste studies have shown the taste characteristics of smoking articles wrapped in reduced sidestream smoke papers to have objectional taste characteristics relative to regular smoking articles. Additional studies have also shown that the pH of the mainstream smoke of tobacco columns wrapped in reduced sidestream smoke cigarette paper is higher than that of the same tobacco columns wrapped in regular cigarette paper. The subjective taste characteristics of cigarettes wrapped in reduced sidestream smoke cigarette paper are similar to that obtained when the pH of mainstream smoke of regular cigarettes is artificially increased. Prior studies have shown that the subjective taste characteristics of the low sidestream cigarettes are significantly improved by reducing the pH of the mainstream smoke.
Owens, U.S. patent application Ser. No. 514,533, filed Apr. 26, 1990, of which this application is a continuation-in-part, reveals the use of organic acids selected from the group of citric, malic, lactic, glycolic, tartaric, fumaric, maleic, malonic, glutaric, adipic, and succinic for treatment of reduced sidestream smoke cigarette papers, to give desirable subjective taste properties approaching that obtained with cigarettes wrapped with regular cigarette paper.
