In addition, the design of the filter should be such that it can be attached to the cigarette by conventional cigarette makers.

Stanje tehnikeThe state of the art

Poznati su filteri za cigarete, čija je konstrukcija takva da omogučava ulazak spoljnjeg vazduha u filter i razblaživanje struje dima koja prolazi kroz filter. Time se smanjuje količina štetnih sastojaka u struji dima koja dospeva u usta pu šača.Cigarette filters are known, the construction of which allows the outside air to enter the filter and to dilute the flow of smoke passing through the filter. This reduces the amount of harmful ingredients in the smoke stream entering the mouth of the smoker.

- 2 Tako je u US patentu Br.3 596 663 opisan filter za cigarete, koji je snabdeven rebrastim pokrivnim omotačem propustljivim za vazduh, koji je postavljen oko jednog dela filtera i oko kojeg je postavljen papirni omotač sa otvorima za ventilacioni vazduh. Usled ovakve konstrukcije vazduh za provetravanje direktno ulazi u deo filtera, a istovremeno duž udubljenja izmedu rebara na omotaču ualzi i u usta pušača.- 2 Thus, U.S. Pat. No. 3,696,663 describes a cigarette filter, which is provided with an air-permeable ribbed cover, which is arranged around one part of the filter and around which a paper wrapper is provided with vents for ventilation air. Due to this construction, the ventilation air directly enters the part of the filter, and at the same time, through the recesses between the ribs on the envelope, it enters and into the mouth of the smoker.
