example 1

[0033] Cigarette A has a 63 mm long tobacco rod 11 and a 21 mm long multipart filter 20 .

[0034] The core 24 of the filter part 23 on the rod side has a diameter of 5.5 mm at a length of 8.0 mm. It is made of cellulose acetate with a single denier of 6.0 den and a total denier of 17,000 den. The pull-out resistance or pressure drop of the core 24 is 27mm water column.

[0035] The sleeve 26 , which coaxially surrounds the core 24 , has an inner diameter of 5.5 mm and an outer diameter of 7.8 mm for a likewise length of 8.0 mm. Cellulose acetate with a single fineness of 2.1 den and a total fineness of 55,000 den can be used as the material.

[0036] Typically the coaxial filter has a length of 8.0mm at a diameter of 7.8mm.

[0037]The filter portion 22 on the mouth side is a single piece and made of cellulose acetate. It has a diameter of 7.8mm at a length of 13mm. In the region of the mouth-side filter part, the ventilation zone is formed in the form of a row of laser ...

[0042] Cigarette B has a 59 mm long cigarette rod and a 25 mm long multi-part filter 20 .

[0043] The core 24 of the filter part 23 on the rod side has a diameter of 5.5 mm at a length of 10.0 mm. It is made of cellulose acetate with a single denier of 6.0 den and a total denier of 17,000 den. The pull-out resistance or pressure drop of the core 24 is 25mm water column.

[0044] The sleeve 26 , which coaxially surrounds the core 24 , has an inner diameter of 5.5 mm and an outer diameter of 7.8 mm for a length likewise of 10.0 mm. Cellulose acetate with a single fineness of 2.1 den and a total fineness of 55,000 den can be used as the material.

[0045] Typically the coaxial filter has a length of 10.0mm at a diameter of 7.8mm.

[0046] The filter portion 22 on the mouth side is a single piece and made of cellulose acetate. It has a diameter of 7.8mm at a length of 15mm. In the region of the mouth-side filter part 22 , the ventilation zone is formed in the form of a row o...

Abstract

The invention relates to a ventilated filter cigarette, which has a wrapped individual cigarette rod (11) and a filter (20) with a ventilation mechanism, which filter tip includes at least two filter parts (22, 23). The ventilation hole (14) is provided in the area of ​​the filter part (22) on the mouth side. In addition, the mouth-side filter part (22) consists of a single filter segment (22), while the strip-side filter part (23) is a filter segment with a core (24) and a sleeve (26) , that is, a so-called coaxial filter part or a coaxial filter.

Description

technical field [0001] The invention relates to a filter cigarette. Background technique [0002] Filter structures for insertion into cigarette filters comprising several filter parts with different material properties are used in the prior art to solve different problems. In addition, the breathability of the filter is used to ensure a moderate smoking and lower inhalation of harmful substances. [0003] EP 474 940 B2 and EP 608 047 B1 describe cigarette filters in which a central core comprises a different filter material than the sleeve. The cigarette filter is also known as a core or coaxial filter. In an embodiment of EP 474 940 B2 (Fig. 5), the filter comprises two longitudinal filter segments, namely the vented rod-side core filter portion and a mouth-side single filter portion, wherein the mouth-side single filter portion The purpose of the filter portion is for aesthetic purposes. A disadvantage of the cigarette filter described above is that the envelope of th...
