KR960703527A - Ventilated filter cigarette - Google Patents

Abstract

A ventilated filter cigarette has a multiple filter with a higher global retention provided in different sections with ventilation perforations. The ventilated filter cigarette contains a tobacco mixture of expanded tobacco having a high nicotine content. The tobacco mixture contains as constitutive element expanded tobacco lamina with a nicotine content from 1.0 % to 8 % and/or tobacco foil with a nicotine content from 5 % to 10 %, to which fruit acid is incorporated. The tobacco mixture has a nicotine content from 2.5 % to 5 %. The resistance to draw of the multiple filter is higher at the tow side than at the mouth side, and the degree of ventilation lies in a range from 50 % to 95 % added air. The main smoke flow preferably has an "American blend" taste with an approximately constant taste per puff. The pH value of the smoke lies in a range from 6.0 to 7.5. While giving good sensory results, the cigarettes have condensate and nicotine values respectively of less than 1 mg/cigarette and 0.1 mg/cigarette and in special cases of less than 3 mg/cigarette and less than 0.6 mg/cigarette.
