CIGARETTE PROVIDED WITH AN INERTIAL HYPOBARIC DEVICE SUCH AS TO RETAIN THE TAR IN TOBACCO SMOKE AND/OR DEVICE AS ABOVE NOT ESSENTIALLY INSERTED INTO A CIGARETTE

摘要

Cigarette fitted with a device suitable to retain the tar contained in tobacco smoke. This device, installed between tobacco (T) or the combusted material and the smoker's mouth, consists of a chamber (IPOB) with a hypobaric action with one (or more) inlet hole(s) (Ca1) by which smoke enters and one (or more) outlet hole(s) (Ca2) through which the smoker inhales the smoke. Within this chamber a state of reduced pressure is created caused by the difference in dimensions between the inlet duct(s) and the outlet duct(s) and the product of combustion is subjected to repeated accelerations and decelerations such as to promote separation of the particles of greater mass and make them deposit on the interior walls of the hypobaric chamber and/or device as above not essentially inserted into a cigarette.
