Definitions

  • the invention relates to cigarettes and has for an object to reduce the efiects of smoking which are detrimental to health, and to enhance the pleasure of smoking.
  • the wrapper filled with tobacco acts almost as a retort, that is incomplete combustion takes place in view of the lack of oxygen, which, on the one hand, causes the valuable aromatic resins to smoulder and to be converted into unpleasant combustion products, and, on the other hand, produces such high temperatures immediately behind the burning zone that, for example, nicotine salts and ammonium compounds are evaporated as colloids, depositing in a most finely divided state in the cooler part of the cigarette.
  • these condensates are particularly easily evaporated if too high a temperature acts on them again, and they thus reach the breathing organs of the smoker undecomposed.
  • This phenomenon known as nicotine rush is not only detrimental to health, but also imparts a pungent, biting taste to the smoke.
  • the efiects of this phenomenon become particularly undesirable as the smoking of the cigarette progresses.
  • the size or number of the holes decreasestowards the mouth end in accordance with the draught resistance of the cigarette which varies according to the distance from the mouth end.
  • the effect thus obtained is that, while the draught resistance is still very high, i. e., while only a small piece of the cigarette has been smoked, the fresh air, which has to overcome the same resistance, enters the comparatively large opening of the perforation adjoining the glowing zone, whereby the air is conducted to the point where it should exert its eifect, viz., in the close proximity of the burning zone.
  • the air admission apertures are burnt away successively the admission of the main quantities of fresh air occurring through the apertures which are situated nearest to the burning end.
  • Their sizes are so chosen in view of the draught resistance of the cigarette known to decrease, from the beginning to the end of the cigarette, from about 40 mms. to about 2 mms. mercury column. This arrangement results in a constant mixingratio of smoking gases and fresh air being maintained closely behind the burning zone during the smoking 01 the whole cigarette.
  • the fresh air which, on principlaenters at the burning zone and which can be accurately dosed by the size of the holes, prevents, on the one smoking period, because the fresh air will, up to hand, the formation of detrimental carbon oxide in-view of its oxygen contents, which is now immediately oxidized into innocuous carbon dioxide in the zone which is still hot. and, on the other hand, the formation of the unpleasant products bility of discharging products of evaporation into the outer atmosphere and to draw in, by the suction produced on the other side, fresh air which assists a priori in checking the formation of unfavourable products of incomplete combustion.
  • Theorganic ammonium salts which dissociate in this phase with particular ease; discharge through this aperture the easily evaporating and detrimental ammonia gas.
  • the size of the holes to be stamped into the wrapper conveniently increases from 0.2 mm. diameter at the mouth end to 1.3 mms. diameter at the burning end.
  • three such holes, distributed over the length of the cigarette and having diiferent diameters according to the resistance to draught, suflice for obtaining the effect of the invention but in certain circumstances it is desirable to subdivide the total size of the aperture in one zone into a plurality of holes in such a manner that the quantity of air drawn through these holes is the same as that, which in other cases corresponds to the one hole calculated in view of the draught resistance.
  • the invention is, naturally, not limited to an arrangement of holes or groups of holes in a definite number of different distances from the mouth end.
  • the number and size of the apertures bethe cigarette paper which is already present in j view of the additions of inorganic carbonates.
  • Figure 1 shows a cigarette with a total of three individual holes arranged in different distances from the mouth end.
  • Figure 2 shows awrapper of the cigarette according to Figure 1.
  • Figure 3 shows a second embodiment where the total size of the apertures in the different distances from the mouth end as determined by the. calculated amount of air. is subdivided into a, number of smaller holes in the same zone.
  • Figure 4 shows the wrapper of the embodiment l accordingto Figure 3.
  • the reference letter a is used to designate the mouth end of the cigarette while the burning end of the cigarette is designated b.
  • a cigarette according to claim 1 wherein a hole is arranged at each of a number of different spaced intervals from the mouth end and said holes decrease in diameter from 1.3 mms. near the burning end to 0.2 mm. near the mouth end.
