Description

Tobacco product

The invention relates to tobacco products such as cigarettes and cigarillos and the like, with a new cover sheet or ^ a new casing made from a film with certain properties and a method for producing the same. The PiIm contains as one component a natural polysaccharide, which is preferably combined with another component, namely a Alkaline earth compound, is combined. The cover sheet or envelope is characterized by a special appearance and others physical properties that differ from those of conventional wrappers or wrappers for tobacco products, such as Cigarette paper and tobacco leaves, as well as also differ from various modified tobacco products that have been made so far used to wrap tobacco products.

The cover sheet or the envelope according to the invention draws differ in different ways. It compresses, for example, the burning or smoldering tobacco coal and thereby reduces it the availability of new fuel for the tobacco coal in the time interval between several puffs. The case

is able to shrink on the carbonization line of the tobacco product during the pyrolysis of the tobacco and significantly reduces the formation of love smoke from the tobacco products of which it forms a component. This feature of the invention enables the preparation of a tobacco product, which when is not pulled from Z ₀ B. when it is located in an ashtray, produces less smoke. When the cover sheet or the casing according to the invention is used for the manufacture of tobacco products, it has been found that these products have an improved taste and aroma.

Tobacco products, such as cigarettes, cigars and the like, are usually wrapped in paper, such as conventional cigarette paper, wrapped in tobacco leaves, such as the cigar wrapper, or in an envelope made of artificially composed material Tobacco is made. The latter consists e.g. of a modified tobacco mass, which consists of tobacco plant parts together with is composed of different binders. Such covers and sleeves are disclosed in U.S. Patents 3,483,874, 3,125,098, 3 416 537, 3 496 947, 3 499 453, 2- 893 400, 2 927 588 and 3,062,688.

The subject of the invention is a special cover sheet or a special cover that has a combination of properties that are found in the previously known cover sheets or covers are not available; the cover sheet or the envelope has the following advantageous properties:

1. The case has a novel appearance and can if necessary be transparent.

2. It can be made non-porous or with various degrees of porosity, as desired.

3. If a casing produced according to the invention for a tobacco product used, it confers as found

- 2 409884/0994

became a mild aroma to the smoke.

4. If a case for cigarettes produced according to the invention is used, there is less irritating effect when the cigarette is smoked, and such cigarettes become preferred by most smokers who wrapped them in conventional cigarette paper as compared to Cigarettes and with cigarillos that have wrappers made from artificially composed tobacco.

5. As a result of their shrinkability at the char line the shell can significantly reduce the secondary smoke of the tobacco product when smoking.

6. It has been found that tobacco products according to the invention Manufactured wrapper sheets or envelopes have a longer shelf life than cigarettes with envelopes made of conventional Cigarette paper and no stains when stored at a high relative humidity of, for example, 85 # receive.

7. As will be explained below, some cover sheets or envelopes according to the invention also have the advantage that they become self-adhesive when moistened with water, so the use of an adhesive in the making of the tobacco product may be unnecessary.

The cover sheet or the envelope according to the invention consists of a film, which by pouring an aqueous solution, Suspension or dispersion of a film-forming agent which has certain properties described below, among film-forming agents Conditions is established. Preferably the film former is a natural polysaccharide. In particular, will the film former combined with an alkaline earth compound.

Natural polysaccharides and derivatives can be used as film formers use the same as well as natural polyuronides, e.g. a pectin or an algin or mixtures thereof; also can

409884 / ~ θ £) 94

a natural galactomannan such as carob resin or guar resin. Other natural polysaccharides that form satisfactory films are karaya resin, acacia resin, Dextrin, agar, starch, caribbean resin, garrageenin and Xanthan gum. The film former is preferably a pectin-like material, guar resin or a mixture of both. Some of the as Film formers for the cover sheets or casings according to the invention usable natural polysaccharides are hydrolyzed Guar resin, carob resin and alginates, which are somewhat less preferred than pectin or guar resin, but as has been found, also develop a relatively low pyrolysis taste. The polysaccharides, especially the pectin-like material and / or guar resin, can be used as the sole film former or with other film-forming agents, such as described below. These substances behave are very cheap and add very little to the taste of the smoke when burned. These substances are in Commercially available or can be prepared by known methods. The pectins can be fruit or vegetable pectins and can be used as commercial pectins obtained from fruits or vegetables or as pectin-containing fruit components, such as Lemon albedo. You can also use pectins that have been methylated to different degrees are.

You can also use various other natural polysaccharides as film formers, which have little taste during pyrolysis to develop. The natural polyuronides, such as the pectins and algins, and the natural galactomannans, such as Locust bean gum and guar gum, are pourable from aqueous solutions or suspensions, and most of them are water soluble.

The basic idea of the invention is the use of a film former, which has the following properties: (1) It wraps around the burn edge of the tobacco product together; (2) it is non-thermoplastic and (3) it has

- 4 -409884/0994

good elongation (at least 1.33 #), determined with the Scott tester, on.

All of the substances mentioned above can be mechanically processed into films that have the required tensile strength and elasticity have, can be torn into ribbons and can be used as covers or cover sheets. A suitable one Adhesive for the water-resistant mime is a water-based adhesive paste. For the water soluble films, to which most of the polysaccharides listed above "with the exception certain magnesium and calcium alginates or pectates and similar water-insoluble materials, water has been found to be suitable as an adhesive.

Pectin and guar resin give the best results. All viscosity grades can be used; from the point of view of a? Balance between the nature of the film and the highest possible solids content in the film-forming slurries however, pectin will be of medium viscosity or Reduced viscosity guar resin is preferred.

Highly thermoplastic films are used for the purposes of unsuitable because the tobacco products made with them! e.g. cigarettes, droopy when smoking; such products also melt and drip slightly on the char line. Commercially available substances that are used for soluble casings or packaging have been recommended, have therefore proven to be unsuitable for the casings according to the invention proven.

Those produced according to the invention from natural polysaccharides Films are not thermoplastic, but become thermoplastic when they are extremely soft. · Under In certain circumstances, therefore, a certain amount of plasticizer can be used act favorably in the sleeves or cover sheets according to the invention; the cover sheets or envelopes according to the invention should.

- 5 409884/0994

len, however, not more than 50 parts by weight of plasticizers, such as Moisturizing or plasticizing agents, 100% by weight. contain parts of natural polysaccharides.

The polysaccharide, especially pectin-like, serving as a film former Material, or guar resin, can be used alone or together with an equal or lesser amount of a second Film former can be used. The second film maker can e.g. a natural polysaccharide such as carob resin or certain calcium or magnesium alginates of high purity, be. However, alginates should not be used together with calcium carbonate or large amounts of calcium or magnesium salts should be used because this can lead to undesired gelling of the alginates.

The alkaline earth compound, which is preferably used according to the invention, is generally first wetted with water, to obtain a dispersion or solution, and then added to the film former. As an alkaline earth compound or Alkaline earth salt is preferably used magnesium or calcium carbonate; however, you can also use inorganic compounds such as oxides, hydroxides, chlorides or phosphates of calcium and / or use magnesium, e.g. water-insoluble minerals such as calcium and / or magnesium orthophosphate, pyrophosphate, polyphosphates, hydroxyapatites and the like. A beneficial mineral for bringing in controlled amounts of Calcium is precipitated triealcium phosphate (type NF). The alkaline earth compound can also be a salt of an organic acid, such as calcium or magnesium citrate, lactate, maleate or the like, be. In addition to the alkaline earth salts of these acids, sodium or potassium salts of these organic acids can also be used Use acids as burning additives. The alkaline earth compound, whether on its own or as a mixture of such Compounds used can be in amounts corresponding to 0 to 60 parts by weight per 100 parts by weight of the natural Polysaccharides are applied; preferably one works

-.6 409884/0994

with amounts corresponding to 8 "to 40 parts by weight per 100 parts by weight Polysaccharide.

One method of making a porous shell is to create it a gel in the casting slurry; this happens usually using a combination of algin or acid pectin with a degree of methylation less than 70 and an alkaline earth mineral or hydroxide and introducing a controlled amount of air immediately prior to potting to the Movie. However, the gel need not necessarily be made in this way. Has a gel in the casting slurry In any case, the beneficial effect that the air bubbles are held until they burst during drying and leave small voids.

A non-essential, but preferred component of the cover sheets or envelopes according to the invention is a plasticizer. The plasticizer is added to give the total mixture the required To impart processability, and the question of whether such a plasticizer is added depends on the respective film makers. Suitable plasticizers are certain tobacco extracts, which are produced by leaching tobacco parts with water, with mixtures of solvents such as acetone, methanol or ■ isopropanol, and water or non-aqueous solvents, such as hexane, tetrachlorethylene, ethyl ether and the like, can be obtained. Other plasticizers are monobasic, dibasic and tribasic acids, such as lactic acid, Malic acid, tartaric acid, citric acid. Other plasticizers are butylene glycols, sorbitol, sorbitan, sucrose, oligosaccharides, Long-chain triglycerides in the form of fats and oils Fatty alcohols, linear paraffins, normal paraffins, paraffin waxes, beeswax, candelilla wax, carnauba wax and sugar cane wax. If one of these substances or a combination of these substances is used, the Tobacco products have a smoke of a taste and aroma that have been judged to be favorable by subjective evaluation

- 7 -409884/0994

are. When a plasticizer is added, it is generally done in amounts ranging from traces to about 5 parts by weight per 100 parts by weight of film former. Humectants such as glycerin, Monoacetylglycerin, triethylene glycol, invert sugar and Corn syrup 'are' preferably used in amounts of about 2 to 40 parts by weight added to every 100 parts by weight of film former. The total amount of plasticizers and / or humectants however, 50 parts by weight per 100 parts by weight of the natural polysaccharides used as film formers should not, exceed.

Other substances that can be introduced into the cover sheets or casings are nicotine-containing extracts from tobacco leaves as well as other flavorings that give the smoke the desired taste. Such flavorings include e.g. licorice, venison tongue, the essential oils of rum, chocolate, fruit essence and the like.

If the mixture is to be poured, it can be made up with a binder to a solids content of 5 to 25 #. The preferred solids content is in the range from $ 9 to $ 15. If the mixture is to be extruded, a much higher solids content, for example $ 80, can be used. For economic reasons, it is advisable to work with a high solids content so that you do not need to evaporate large amounts of water per kg of product. -

Films produced according to the invention can be cast, dried, conventionally cut into strips of suitable width for the envelope in question and in the same shape Way be fed to a cigarette stick machine, in which one feeds a strip of cigarette paper. Then the Manufacture of the cigarette stick in the usual way, with the difference that in most cases the glue by water, mixtures of water and alcohol or lime water

- 8 409884/099 /,

can be replaced. This glue is applied in the same way along the edge of the envelope (usually with a cardboard wheel or felt wick), so that when the edges overlap and pressure is applied from the closing organs is brought, the envelope is closed and a finished rod is produced. The application of heat required is when you work with cigarette paper and glue, may be superfluous in the present case.

The films are generally 19 to 56 microns thick (this refers to its true thickness, determined under "Avoidance of TJ irregularities". However, if fibers are present, as with Citrusalbedo, the film can be thicker, e.g. 130μ thick, be. If transparency is not required, a white pigment such as titanium dioxide can be added.

The films produced according to the invention should preferably have a shrinkage factor of at least 4 #. The shrinkage factor is determined by placing a measured strip of the film about 25 to 50 microns thick on a hot plate, covering the film with a sieve of about 1.2 mm mesh size to prevent it from curling up, and medium temperature, ie one of 177 - 28 ° G, brings about. The film should preferably shrink by at least about 1.0 i * of its length, but preferably by no more than about 16.0? £ of its length.

4.0 g of "ashless" carboxymethyl cellulose (CMC) (grade 0.75 / 3.0), which is the acidic form of carboxymethyl cellulose are dispersed in 100 ml of water. The CMC has an acid number of 230 mg KOH / g. 0.290 g powdered Calcium hydroxide is stirred into 5 ml of water, and the mixture is then stirred into the CMC dispersion. The pH the dispersion thus obtained is 8.5.

The two dispersions are combined in a Waring mixer with vigorous stirring. The mixture is stirred for a further 1 minute, whereupon a gel with a pH of 7.5 has formed. The gel is placed on an endless stainless steel belt at room temperature Poured steel and dried the film with steam. A clear, firm film slightly thick is obtained more than 25 μ and a basis weight of 18.3 - 4.3 g / m.

The film is used as a wrapper for a commercial tobacco insert, and 10 cigarettes are made using this Films rolled by hand as the only wrapping material. The cigarettes are made using in the usual way Water rolled as an adhesive by simply wrapping the overlapping ends of the film around the tobacco filler moistened with water. Experienced cigarette smokers who smoke these cigarettes put the same smoke in the same Way like traditional paper-wrapped cigarettes. They find that the cigarettes are unusually mild and have a much more tobacco-like character.

an acid number of 40 to 60 and a methylation rate of Contains 60 to 80 # and fiber material, is adjusted to a pH of 11.0 with potassium hydroxide solution. Then you leave that Stand mixture at room temperature for 30 minutes; after this period the pH has dropped to 9.0 and remains at this Constant height. 200 g of this slurry, which has a pH of 9.0, are placed in the Waring blender for 15 minutes touched. Then add 1.5 g calcium chloride (a 10 percent excess) to the mixture in the Waring blender Form a 10 percent aqueous solution and stir it Dispersion for a further 15 minutes at room temperature. The calcium pectate porridge, which has a pH of 8-9, is pressed into a cake to remove excess water, and washed in a mixture of equal parts by volume of acetone and water, whereupon the one containing the excess salts Removed washing liquid. The material thus obtained is dried to a fine white powder.

1 part of this white powder, which essentially consists of a neutral mixture of calcium pectate and hemicellulose pulp consists, is slurried in 20 parts of water and with 0.2 part of ammonium carbonate, 0.2 part of ammonium citrate, 0.015 part of potassium citrate and 0.1 part of calcium carbonate mixed. The mixture is stirred for 15 minutes, during which a gel with a pH value of 9 forms, which then increases to endless Stainless steel tape is cast into a film with a wet thickness of 0.76 to 1.27 mm. The finished film is clear, firm and has a thickness of 75 to 130 μ and a basis weight of 43 to 65 g / m.

The film is used as a cover for a technical tobacco insert, and 50 cigarettes are hand-rolled with this film as the only wrapping material. Experienced cigarette smokers, those who smoke these cigarettes produce the same smoke in the same way as conventional paper-wrapped cigarettes fixed. You will find the cigarettes exceptionally mild with a much more tobacco-like taste.

In both cases the solutions will take 18 hours (overnight) stored before being mixed again and for pouring Films are used.

The resulting gel is poured onto an endless stainless steel belt, and the resulting film, once equilibrated at 24 ° C and a relative humidity of 65 fi , has a thickness of 43 μ and a basis weight of 32 g / in, when it has been cast with the aid of a Gardner squeegee in a wet thickness of 0.63 mm.

The film is used to wrap a technical tobacco insert used. Ten cigarettes are hand-rolled using this film as the only wrapping material. The film (using water as an adhesive) by simply wetting the overlapping edges with water when Wrapping the tobacco pad and applying pressure glued to itself in the usual manner. Experienced cigarette smokers, those who smoke these cigarettes produce the same smoke in the same way as usual, paper-wrapped ones Cigarettes solid. They find the cigarettes extraordinarily mild and are much more similar to tobacco Character solid.

Examples 4 to 21

The following films are made by dispersing the specified polysaccharide in 200 parts of water, having previously dispersed the powdered alkaline earth compound in the water and the required humectant therein has been resolved. Another method is to stir the mixture in the Waring blender for 0.5 to 1.0 minute with the wetting agent first dispersed and mixed with the dry polysaccharide, and the partially gelled product is cast in a thickness of 0.63 mm, the film is dried and cut to suitable widths for the production of Cut up cigarettes. In all examples where pectin

The mixture will Digested for 30 minutes, refined and chilled in the Waring mixer. A mixture of 0.6 g of triethylene glycol, 0.4 g of potassium citrate and 0.1 g of potassium sorbate is added to the albedo mixture in the mixer, dissolved in 5 to 10 ml of water, added. The pH is adjusted to 6.1 by adding 1.3 g of concentrated aqueous ammonia. By adding 1.5 g of powdered Calcium carbonate gives a dispersion with a pH value from 7.0 to 7.5.

If this is stirred at high speed, then poured and the resulting film is dried, you get a very thin product with many pinhole-like markings that only turn out to be extremely thin spots under the microscope, possibly caused by bubbles. Cigarettes are produced with this film as wrapping material, the wrapping being glued by wetting. if The cigarettes are smoked, they burn statically in the same way as paper wrapped cigarettes, being one stale charring line remains behind the coal and the shell is less prone to collapse along this line than the PiIn of the previous examples.
