Definitions
- the present invention relates to an improved smoking article wrapping material useful in smoking articles, e.g. Cigarettes that reduce carbon monoxide as a constituent of smoke ingredients without altering the air permeability of the tobacco wrapper paper in the unburned state.
- the known inventions and applications are aimed directly or indirectly at a change in the air permeability of the tobacco product wrapping material, which reduces all smoke ingredients and changed the number of smoking products in only slightly changed proportions.
- the CO reduction catalysts used in the prior art change the appearance of the tobacco wrapper papers or do not conform to legal regulations.
- the aim of the present invention is thus to overcome the above-mentioned problems and to provide a tobacco product wrapping material, which allows a reduction of the carbon monoxide content of the smoke ingredients with unchanged air permeability.
- the inventors of the present invention have found that the above object is achieved by a smoking article wrapping material containing as filler two calcium carbonate different in particle size and amount.
- a tobacco ware wrapping material containing calcium carbonate of different particle size as a filler, one of the calcium carbonates having a particle size of 0.1 to 2 ⁇ m and an amount of 51 to 99%, based on the total content of calcium carbonate fillers. and another calcium carbonate has a particle size of 3.5-10 microns and is contained in an amount of 1-49% based on the total content of calcium carbonate fillers.
- the tobacco product wrapping material according to the invention is a cigarette paper.
- the total filler content of the tobacco product wrapping material according to the invention is 10 -50%, preferably 25 to 40%, based on the total weight of the tobacco product wrapping material.
- the calcium carbonates used according to the invention are calcium carbonate having a particle size of from 0.1 to 2.0 ⁇ m, preferably from 0.3 to 1 ⁇ m, in an amount of from 51 to 99%, preferably from 70 to 95%, based on the Total amount of the fillers, as well as a second calcium carbonate having a particle size of 3.5 -10 .mu.m, preferably 4 to 6 .mu.m, in an amount of 1 -49%, preferably 5 -30%, based on the total amount of fillers , is included.
- further fillers such as calcium carbonate of a different particle size, titanium dioxide, magnesium oxide, talc or kaolin may optionally be added to the tobacco product wrapping material according to the invention.
- the differentiation of the particle size of the calcium carbonate causes in the combustion process of the tobacco product wrapping material in combination with a manufactured therefrom smoking product, preferably cigarette, the formation of an outer ash tube, which shows a particularly porous structure.
- the porous structure of the smoldering tobacco wrapper paper is essentially determined by the inventive combination of two different in particle size and amount calcium carbonates and the total amount of calcium carbonate and only slightly by the level of air permeability of the tobacco product wrapping material.
- the tobacco product wrapping material of the present invention may optionally include a burning rate retarding substance and / or a burning rate accelerating substance.
- the substance delaying the burning rate can be called diisodium hydrogenphosphate.
- Alkali or alkaline earth metal salts such as sodium, potassium and magnesium salts, or carboxylic acid salts, such as acetic, citric, malic, lactic and tartaric salts, in particular citric acid salts, can be used according to the invention as the fuel-speed-accelerating substance.
- the proportions of the respective constituents in the inventive tobacco product wrapping material are, based in each case on the total weight of the tobacco product wrapping material, usually - if present - 0-6%, preferably 0-3%, the burning rate retarding and / or accelerating substance.
- Tobacco wrap material is usually made of cellulosic fibers obtained, for example, from flax, softwood or hardwood. In order to alter the properties of the base wrapper material, if desired, various blends of cellulosic fibers may also be used as the base wrapper material.
- the basis weight of the tobacco product wrapping material used according to the invention is usually 15 to 60 g / m 2 , preferably 18 to 40 g / m 2 .
- a further aspect of the present invention is a method for reducing the carbon monoxide content in the flue gas, wherein a
- calcium carbonate fillers of different particle size are incorporated in a suitable mixing ratio, one of the calcium carbonates having a particle size of 0.1 to 2 ⁇ m and 51 to 99%, based on the total content of calcium carbonate fillers, is incorporated, and another calcium carbonate has a particle size of 3.5 to 10 microns and is incorporated in a proportion of 1 to 49%, based on the total content of calcium carbonate fillers.
- the air permeability of the tobacco product wrapping material can be maintained.
- the inventive incorporation of said Calciumcarbonatyogllstoffe the proportion of carbon monoxide in the flue gas and the ratio of carbon monoxide to dry condensate can be reduced in a favorable and desired manner.
- a further aspect of the present invention is a tobacco article comprising a tobacco rod, a tobacco product wrapping material, the filler thereof, two calcium carbonate particles of different particle size and quantity, each having a particle size of 0.1-2 ⁇ m and 51-99%, and 3.5-10% ⁇ m particle size and 1 -49% proportion, and optionally comprises a filter.
- the particle size of the calcium carbonate used according to the invention was determined by means of a sedigraph.
- the subject of a further aspect of the present invention is a method for reducing the Koh ⁇ enmonoxidgehalts of smoke content substances in a tobacco product comprising a tobacco rod, a tobacco product wrapping material and optionally a filter, wherein the method is characterized in that in the Rauchwarenumhüllungs ⁇ material as a filler calcium carbonate different Particle size are incorporated, wherein one of the calcium carbonate has a particle size of 0.1 to 2 microns and in an amount of 51-99%, based on the total content of calcium carbonate fillers, incorporated and another calcium carbonate has a particle size of 3.5 -10 microns and incorporated in an amount of 1-49%, based on the total content of calcium carbonate fillers.
- Cigla 60 air permeability 60 CU, sodium salt of sodium acetate, 33% filler content, 25 g / m 2 , Julius Glatz GmbH, Neidenfels
- the filler is composed of 80% Precarb 720 (average particle size 0.5 ⁇ m according to Sedigraph measurement, Schaefer Kalk, Dietz) and 20% Precarb 160 G (average particle size 4.2 ⁇ m according to Sedigraph measurement, Schaefer Kalk, Dietz) ,
- Cigla 60 air permeability 60 CU 5 Glimmsalz potassium citrate, 29% filler content, 25 g / m 2 , Julius Glatz GmbH, Neidenfels
- the filler is composed of 80% Precarb 720 (average particle size 0.5 ⁇ m according to Sedigraph measurement, Schaefer Kalk, Dietz) and 20% Precarb 160 G (average particle size 4.2 ⁇ m according to Sedigraph measurement, Schaefer Kalk, Dietz) ,
- the smoke constituents determined were: Carbon monoxide 6.6 mg / cig Dry condensate 6.3 mg / cig Carbon monoxide / dry condensate 1, 05
- Cigla 60 air permeability 60 CXJ, glow salt sodium acetate, 33% filler content, 25 g / m 2 , Julius Glatz GmbH, Neidenfels
- the filler is composed of 100% Precarb 122VP (average particle size 1.6 ⁇ m according to Sedigraph measurement, Schaefer Kalk, Dietz).
