Definitions

  • the invention relates to a wrapper for smokers' articles, in particular for self-extinguishing cigarettes, made from cellulose, containing fillers and optionally glow salts.
  • a cigarette is known from EP-A-133 575, the tobacco cylinder of which is coated with two different papers. Both papers are made of cellulose and have approximately the same basis weight of 20 to 25 g / m2.
  • the porosity of the inner paper is about 1 CU (Coresta Unit), that of the outer paper about 55 CU.
  • the inner paper is filled with 14% by weight titanium dioxide, the outer paper with 30% by weight calcium carbonate and additionally with 6% by weight anhydrous potassium citrate.
  • the low porosity of the base paper is achieved by brushing or soaking with suitable water-soluble, film-forming materials, for example methyl cellulose, carboxymethyl cellulose, starch, chemically modified starch, guar gum, sodium alginate, dextrin, gelatin and the like.
  • a cigarette with this wrapper should go out on its own within a few minutes as soon as it comes into contact with objects - upholstery, carpets, furniture - that prevent the free access of oxygen to the ember cone.
  • EP-A-133 575 also describes solutions with only one paper. Acting it is again a lightweight paper with approx. 20 to 25 g / m2 basis weight and a porosity of 1 to 4 CU, filled with titanium dioxide and / or calcium carbonate as follower and 1.7 to 9% by weight of anhydrous potassium citrate as glowing salt.
  • Another advantageous property of the self-extinguishing smoking articles is that the so-called sidestream smoke, which rises from the ember cone during the pause between two puffs, is reduced.
  • This sidestream smoke is largely responsible for so-called passive smoking. It would be desirable to completely suppress the formation of sidestream smoke; nevertheless, its creation is inevitable, since smoking articles require a constantly burning ember cone for reasons that are easy to see.
  • smoking articles with reduced sidestream smoke are known, which are wrapped with two papers.
  • the inner layer is a highly porous cellulose fiber paper with embedded, finely pulverized carbon, whereby alkaline earth metal carbonates can optionally be added.
  • the outer layer is a normal cigarette paper.
  • the carbon-filled inner paper may or may not be taped; if necessary, it is held by the outer paper. In this proposal, the carbon in the inner paper is to adsorb the sidestream smoke generated so that it is not visible without slowing down the burning of the tobacco.
  • DE-A-37 21 204 also discloses cigarette papers which contain an essentially water-insoluble and thermally stable filler in the cellulose starting material, which provides a surface area in the web of at least 80 m2 per square meter of the web under smoke conditions and up to approximately Contains 15 wt .-% of an alkali metal salt.
  • the porosity is in the range from 5 to 30 CU.
  • a cigarette is known from US-A-3 633 589, which is wrapped with two papers.
  • the cover paper is a conventional, porous cigarette paper with good burning properties and ash qualities.
  • the base paper consists of a practically non-porous paper.
  • the inner paper burns more slowly than cover paper and tobacco. . With every train, the air must pass through the embers. As a result, the mainstream smoke should contain little air, create a rich, unadulterated feeling of smoke and thus reduce the tendency for inhalation by smokers. Secondary smoke or self-extinguishing are described in this document not mentioned.
  • the coverings have unattractive optical properties, be it that they are colored gray or brown, that they form gray or even black ash, that there is no closed ash hose and / or that condensate or tar penetrate and form unsightly brown spots .
  • the present invention has for its object to provide a wrapper for smoking articles, especially for self-extinguishing cigarettes, which can be applied to the tobacco in just one operation, shows no condensate penetration, forms a stable, white ash hose and the transfer of degradation products in the Wrapping chemicals provided in the mainstream smoke largely prevented.
  • top layer and bottom layer must also be coordinated with one another to the extent that perfect processing in the paper machine etc. is possible.
  • the shrinking behavior of the top and bottom layers must be coordinated so that a wrinkle-free bond is possible, that the finished paper does not roll or throw and can be easily wrapped around the tobacco rod.
  • an advantageous further development is to apply a third paper layer as counter lamination to the free surface of the lower layer. At least the mechanical properties of the third paper layer should correspond approximately to those of the cover layer.
  • the cover layer has a weight per unit area of 30 to 40 g / m2, preferably approx. 35 g / m2, the underlayer 6 to 12 g / m2, preferably 8 g / m2.
  • the underlayer can therefore be kept very thin in comparison to the top layer, so that it practically does not impair the good glow properties of the top layer. Self-extinguishing is ensured by the fact that the tobacco burning zone behind the ember cone is depleted of oxygen.
  • the air permeability of the cover layer is preferably greater than 40 CU, which facilitates processing on the paper machine, that of the lower layer less than 2 CU, which improves self-extinguishing. Ultimately, however, the pore-poor to non-porous nature of the paper composite is decisive.
  • the absorbency of the top layer given as the preferred value, of 12 ⁇ 2 mm / 10 min, measured according to the clamping method in accordance with DIN 53106, also serves for perfect processing on the paper machine, as does the value given for the roughness of the top layer, 50 ⁇ 10 mm. Seconds.
  • the invention proposes either to fill the underlayer with tobacco dust and / or aroma substances, or to introduce these substances between the top layer and the underlayer before they are laminated on the paper machine. Both methods can also be combined.
  • Cover paper and base paper are preferably cellulose papers, the cellulose being able to be obtained from annual plants such as flax, hemp or esparto, from annual plants such as pine, birch or eucalyptus or from mixtures of the aforementioned fibers.
  • Fig. 1 shows a section through a cigarette with a two-layer wrapper.
  • the paper enveloping a tobacco rod 4 has a top layer 1 and a bottom layer 2 and was produced by wet lamination on the paper machine.
  • the properties of such a cigarette result from the following
  • Fig. 2 shows a section through another cigarette with a three-layer wrapper.
  • the tobacco rod 4 is coated with a paper with a top layer 1 and a bottom layer 2.
  • the bottom layer 2 is backed with a third paper layer 3 in order to prevent the paper from being thrown or rolled.
  • the mechanical properties of the third paper layer 3 should roughly match those of the cover layer 1.
  • tobacco dust, flavorings and other ingredients can be introduced.
  • a wet laminate on the paper machine produced a paper composite with the following properties: Weight 38 g / m2 Gross density 0.67 g / cm3 Air permeability approx. 10 CU.
  • the self-extinguishing time is approximately 300 seconds.
  • a paper laminate with the following properties was produced from it by wet lamination on the paper machine: Weight 45 g / m2 Gross density 0.67 g / cm3 Air permeability 7 CU
  • the self-extinguishing time is approximately 150 seconds.
  • a paper laminate with the following properties was produced from it by wet lamination on the paper machine: Weight 38 g / m2 Bulk density 0.79 g / cm3 Air permeability 1.5 CU
  • the self-extinguishing time is approximately 120 seconds.
  • a paper laminate with the following properties was produced from it by wet lamination on the paper machine: Weight 52 g / m2 Bulk density 0.76 g / cm3 Air permeability 0 CU.
  • the self-extinguishing time is approximately 90 seconds.
  • the time until the ember cone goes out can be influenced by the diameter, the degree of stuffing and the type of tobacco.
  • the condensate, nicotine and carbon monoxide values in the mainstream smoke are controlled by the tobacco mixture, the tobacco weight, suitable cigarette filters and ventilation mouth sticks.
