Filters for smokers' items, especially cigarettes, Cigars, cigarette holders, tobacco pipes etc.

The subject of the invention is an improvement of the known filters for smoking objects, in particular cigarettes, cigars, Cigarette holders, tobacco pipes etc.

In the previous versions of the filter, the major disadvantage was that if you smoke for a long time, there is a part of the bottom on the floor the jacket sleeve in the area of the smoke passages lying at the same level tobacco sauce made of condensed water and tobacco tar

accumulates, which relatively quickly lead to constipation of the latter. The self-produced tobacco sauce does not filter the tobacco smoke itself, so that the filtering effect is unsatisfactory. The conventional tobacco smoke filters also did not teach an actual condensation and distillation process and a subdivided compression of the tobacco smoke, as is essential for effective filtration.

The new filter is distinguished from the known designs in that in the area of the hair-thin passages on the front side of the deflection pipe means are provided to increase the nicotine and tar excretion to compress the tobacco smoke through , combined with filtration and a condensation To subject the distillation process, furthermore, that a sack space adjoining the intermediate space and lying below the passages is arranged, which balances the draw resistance and the accumulation of the tobacco sauce resulting from smoking with simultaneous filtration.

The drawing shows an example embodiment of the subject matter of the invention shown, namely show:

Fig. 1 is an axial section through the filter in

several times enlarged scale, FIG. 2 a plan view of FIG. 1, Fig. 3 is an axial section through part of

Jacket sleeve and

A jacket sleeve 1 provided at its outer end with an enlarged plug-on part 1 'for a cigarette or cigar 11 is the other in turn provided with the bottom part 2, which on a central outlet opening 4 into the space of the jacket

sleeve 1 protruding to this coaxial exhaust pipe 5 carries. The jacket sleeve 1 and the exhaust pipe 5 are made in a single piece from plastic. 6 is a joint tube made of plastic that is slipped over the exhaust pipe 5 from the outer end of the jacket sleeve 1 and is coaxial with the jacket sleeve . 7 denote the passages for the smoke entrance. The deflection tube 6 is closed at its outer end by a cover 3 and is provided with four guides ρυβη 10 protruding radially crosswise on the tube jacket. The deflecting tube 6, which is open at the bottom, has passages 7 ¹ formed by hair-thin edge cutouts on the end faces opposite one another. The latter are hardly visible to the eye in their natural size. ^{A step-like foot part 5 1 of} the flue pipe 5 at its transition point to the base part 2 has an annular shoulder 12 and, at a distance above this, a conical, upwardly tapering intermediate piece 12 ^! on. When the deflection tube 6 is inserted into the jacket sleeve 1, the guide ribs 10 together with the intermediate piece 12 'center the deflection tube 6 between the jacket sleeve 1 and the extraction tube 5.,

The annular shoulder 12 serving as a seat for the inner end of the deflection tube 6 is arranged at a distance χ above the base part 2 of the jacket sleeve 1. As a result, a relatively deep bag space 8 ^{1 is formed} below the passages 7 ¹ for the accumulation of the tobacco sauce. The fact that the passages 7 ^{1 are} at a distance above the base part 2 prevents the tobacco sauce from directly penetrating and thus prevents clogging.

The conical intermediate ^{piece 12 1} near the base part 5 ^{1 of} the exhaust pipe 5 creates a narrowing of the intermediate space 9 between the exhaust pipe 5 and the deflecting pipe 6. The filtration begins after the passages 7 ¹ and the tobacco sauce can see in the space 9 and in the central outlet opening 4 in the exhaust pipe 5 to the final exit, evenly distributing smoke flue after flue, move without clogging the passages. It will be there-

guaranteed by the suction and enough space for the tobacco sauce created. At the same time, the tobacco smoke also filters through the self-produced tobacco sauce.

The condensing and distilling process that sets in is as follows: The heated tobacco smoke moves with considerable speed through the space of the passages 7 and heats the thin wall of the deflecting pipe 6. The exhaust pipe 5 is relatively little covered by this heating because it does not work with the former is in contact. As a result, a state of condensation arises, twice in the narrowed space 9 ^! and secondarily in the extended room 9.

The passages 7 'combined with the constriction 9' cause a considerable compression of the tobacco smoke, the bag space 8 ¹ bleaching out the brusque congestion of the smoke flow in a positive sense. According to the Oractic experience, this process is important to us. The bag space 8 · is decisive for a normal draw resistance with high filtration at the same time.

The illustrated and described filter is based on investigations a surprisingly good one from official laboratories Nicotine excretion of an average of 75% of that contained in smoke Nicotine and tar excretion averaged $ 70 of the tobacco tar in smoke.
