Abstract

1,093,710. Cigarette filter. P. LORILLARD CO. Nov. 3, 1966 [Nov. 12, 1965], No. 49280/66. Heading A2C. A tobacco smoke filter comprises a plug of porous absorbent material 14 containing an indicator which changes colour in the presence of a significant amount of a selected component of tobacco smoke. The plug 14, wrapped in a transparent film, is united to a paper-wrapped plug 13 of fibrous material by a transparent uniting band 18, and the double filter is united with a cigarette 19 by a tipping paper 20 having an observation opening 21. The plug 14 is formed of crimped, absorbent crepe-like paper impregnated with an indicator by spraying with a solution thereof during the filter rod manufacturing process. The solution preferably also includes a reagent that will react with carbonyl, acidic or basic constituents of tobacco smoke. Accordingly, there are employed carbonyl sensitive indicators malachite green and pararosaniline in combination with a sulphite, the acid-base indicators 1-(2, 4-dinitrophenylazo)-2-naphthol-4-sulphonic acid, brilliant yellow and methylene blue with sodium bicarbonate, and the acid-base indicator bromocresol green with citric acid. The indicators methyl violet, crystal violet and acid fuchsine are also specified. The filters may also be used in cigarette holders designed therefor.
