Abstract

Филтър за цигари, който включва порьозен филтриращ стълб с цилиндрична форма, обвивка, простираща се в надлъжно направление на този филтриращ стълб от единия му край до другия, която обвивка го обхваща, при което се образуват противоположните, свързани един с друг краища на този филтриращ стълб и най-малко един канал, направен в него, при това този поне един канал е отворен в единия карй на филтриращия стълб и се простира от там в надлъжното му направление на разстояние, което е по-малко от дължината на филтъра, характеризиращ се с това, че с цел да се намали количеството на катрана на тютюневия дим, обвивката, която обхваща филтриращия стълб, е изготвена въздухонепроницаема на местата, където тя представлява стените на канала, а в останалата си част е въздухопроницаема, а цигарената хартия, която се простира в надлъжно направление от филтърния стълб и която го обгръща, пропуска въздух. Патентните претенции са формулирани в 1 точка
