Abstract

Изобретение относится к сигарете с содержащим активированный уголь фильтром, которая содержит окруженный сигаретной бумагой табачный жгут, двойной фильтр, часть которого со стороны жгута состоит из углесодержащей папиросной бумаги, и проходящую в направлении периферии вентиляционную зону фильтра в части со стороны рта из ацетата целлюлозы. Папиросная бумага части фильтра со стороны жгута является очень объемистой бумагой, содержащей 20-50 мас.% микроизмельченного активированного угля. Соотношение производительности задержания конденсата между частями фильтра со стороны жгута и рта составляет 1 к 2. Воздухопроницаемость сигаретной бумаги составляет 40-100 Coresta-единиц. Степень вентиляции фильтра составляет 5-60%.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a cigarette with an activated carbon filter, which contains a tobacco rope surrounded by cigarette paper, a double filter, part of which on the harness side consists of carbon-containing tissue paper, and a ventilation zone in the mouth part of cellulose acetate. The cigarette paper of the filter part on the harness side is a very voluminous paper containing 20-50% by weight of micronized activated carbon. The ratio of condensate retention performance between parts of the filter on the harness and mouth side is 1 to 2. The air permeability of cigarette paper is 40-100 Coresta units. The degree of ventilation of the filter is 5-60%. The international application was published along with an international search report.
