Definitions

  • This invention relates to novel cigarette and smoking tobacco including a temperature control substance to produce smoke which is cooler, milder, and of greatly reduced nicotine and tar content.
  • the invention also concerns novel cigarettes and tobacco products prepared with such tobacco.
  • a sufficient quantity of a temperature control substance united with water in substantial amounts either chemically or physically, or both, retaining its water content at substantially the same level under all normal conditions of temperature and atmospheric humidity, and which will relinquish said moisture readily, at temperatures from about C. and above.
  • the temperature control substance and the products resulting from the substance being burned with tobacco must have the properties of being non-toxic and harmless to the smoker.
  • hydrous refers to the temperature control substance united with a substantial amount of water either physically or chemically.
  • Efforts have been made in the prior art, directed to the incorporation in tobacco or in cigarettes of materials designed to aid combustion by increasing the porosity of the tobacco, or for absorbing moisture generated during the process of combustion. These expedients in fact effectively tend to raise the combustion and smoke forming zone temperature, thereby bringing about an even greater formation of toxic and carcinogenic compounds. It has also been proposed in the prior art to incorporate into tobacco very small quantities of adsorbents, such as silica gel, activated carbon, or ferric oxide to act as carriers for flavoring additives such as menthol or licorice or various flavoring oils, the flavoring material being released therefrom upon heating. These substances are added for this purpose, or as smoke filtration or fixing agents, in very small amounts.
  • adsorbents such as silica gel, activated carbon, or ferric oxide to act as carriers for flavoring additives such as menthol or licorice or various flavoring oils
  • a temperature control substance of the character described, to be added to tobacco within the contemplation of our invention includes any of a variety or combination of materials, especially aluminiferous material, such as, for example, fluffy alumina, activated alumina, activated bauxite, and crystalline hydrated alumina. These substances all either contain or are capable of uniting or holding substantial amounts of sorbed water which they readily release when exposed to heat. All are non-toxic and relatively stable under ordinary temperature and humidity.
  • the aforementioned substances in a state in which they contain large amounts of heat-releasable sorbed water, whether bound physically or chemically, are incorporated into tobacco in such proportions, relative to the weight of the tobacco, that a substantial portion of the heat evolved in the combustion of the tobacco will be utilized in liberating and vaporizing the water content and in heating the control substance and its water content to the combustion temperature.
  • temperature control substance designated. herein as fluffy temperature control substance
  • the new type of temperature control substance is light and somewhat fluffy in texture and appearance, more porous, more moisture absorptive, and about two times li hter than the temperature control substance from which it is made. It is especially adapted for incorporation into tobacco wherein the combustion of the adhesive binder admixed with the particles enables the temperature control substance to dissipate into powder with the cigarette or tobacco ashes after burning, a feature of commercial importance.
  • finely divided ordinary temperature control substance such as activated alumina or activated bauxite, or a combination of two or more of these or other materials are reconstituted by treatment with a nontoxic adhesive which is capable of losing its adhesiveness at the burning temperature of the tobacco, permitting the alumina or bauxite to disperse.
  • activated alumina or activated bauxite having a particle size between about 50 and 200 mesh, is admixed with a suitable gum adhesive, such as a vegetable or synthetic gum, for example gum arabic or gum tragacanth, in an amount ranging from about 5 to percent by weight of the temperature control substance.
  • a suitable gum adhesive such as a vegetable or synthetic gum, for example gum arabic or gum tragacanth
  • the mixture after exposure to moisture for a suitable period, followed by air drying, may be comminuted to about 14 to 40 mesh size, and then exposed again to moisture, the moisture content thereby rising to about 18 to 22 percent.
  • the starting material such as activated bauxite or activated alumina
  • a solution of gum arabic separated by decantation or filtration, and then dried to a powder having the desired water content.
  • the fiulfy temperature control substance may be made less dense by aerating it during its manufacture, such as by stirring or blowing air bubbles into it or incorporating a small amount of a material which liberates or changes to a gas.
  • the starting material is not of a desired color it can be dyed with a brown tinting agent to match tobacco shades, such as, for example, in the case of activated alumina, by spraying or immersion, in a solution of ferric ammonium oxalate, having a concentration between about 0.5 and 10%, for example, g. per liter, at a temperature of about 140 'F., for a period of about 2 to 5 minutes.
  • the dyed alumina is separated and air dried to the desired moisture content. Then from about 5 to 10 percent by weight of dry natural gum, such as gum arabic or gum tragacanth, is added to the dry tinted alumina powder, and thoroughly mixed therewith until uniform.
  • alumina or other materials can be tinted by admixing therewith a small amount, about 0.5 to 2 percent of bauxite which, because of its impurities, principally iron oxide, is naturally of a suitable color.
  • a solution of a suitable brown organic dye may be employed for this purpose, such as, for example, Gold C (Sandoz) which is a mixture of metallized monoazo dyestuffs.
  • the new fluffy temperature control substance thus prepared can be more readily admixed with ordinary tobacco, from which it does not tend to separate. Upon exposure to heat, such as that generated in the combustion of tobacco, the gum arabic or other gum loses its adhesive properties and the hydrous temperature control substance particles readily are dispersible to a fine powder.
  • activated alumina which is essentially a mixture of various crystalline forms of aluminum oxide, is a material having a low density and a large surface area per unit weight and a highly porous structure. It is produced by heating alumina hydrate to a temperature sufiicient to drive off most of the combined water, but is capable of absorbing from 16% to 20 additional moisture, depending upon the relative humidity of the moisture atmosphere to which it is exposed.
  • activated alumina In forming activated alumina, the alumina hydrate should not be heated so high as to produce any significant amounts of gamma or alpha alumina, which usually begin to form at temperatures above about 850 C. The moisture absorbed by the activated alumina is readily releasable at temperatures as low as about 165 C.
  • hydrous activated alumina of the character described may be incorporated as such or in fluify form into tobacco to control temperature of the combustion products by release of sorbed Water upon exposure to heat, and by absorption of heat required to raise it and its water content to the combustion temperature.
  • activated bauxite As an alternative to activated alumina, there can be used as a temperature control substance, in accordance with our invention, activated bauxite. This is prepared from bauxite in a similar manner as activated alumina is prepared from alumina hydrate. Bauxite is a naturally occurring ore of aluminum and is an impure form of alumina, primarily alumina trihydrate, containing small amounts of the oxides of iron and other impurities. The activated form can have a residual moisture content as low as about 2 percent. It can be hydrated up to about 2-6 percent moisture content, this sorbed moisture being releasable upon heating.
  • Alumina trihydrate (Al O' .3H O) is a dry, free flowing crystalline powder, produced from dry process sodium aluminate, and containing about 50% moisture based on A1 0 content which is readily releasable upon heating to temperatures of 110 C. and above.
  • Temperature control substances such as the foregoing substances, or mixtures thereof, united with water, in accordance with this invention, are incorporated into tobacco in amounts at least 20 by weight of the tobacco, but advantageously ranging from approximately 20% to about by weight of the tobacco, and preferably in an amount ranging from about one part by weight to four parts of tobacco (251% of the weight of the tobacco) to one part to two parts of tobacco (50% of the weight of the tobacco).
  • the precise amount to be added is influenced by such factors as the type of temperature control substance, type of tobacco, moisture content of the tobacco, degree of shredding, the cigarette paper used, types of flavoring and other additives present, and the like. It appears that the quantity of hydrous temperature control substance present is such that in addition to moisture 'release, a substantial filtering action by the alumina parr ticles, both hydrated and dehydrated, is available to the smoker.
  • the particles should not be so small as to result in substantial loss or maldistribution of the substance through sifting or change of position between the tobacco particles.
  • 14 to 28 mesh particle size of the control substance has been found generally satisfactory.
  • a binder it is possible and preferable to utilize the smaller sizes, for example from 50 to 200 mesh, and down to 325 mesh and below.
  • Any suitable binding agent may be used, such as, for example, dextrin, sorbitol, carboxymethylcellulose, vegetable or synthetic gums, or the like.
  • the amount of binder may be varied as desired; for example, it may range from about 1 to 5 percent or more by weight of the tobacco, depending on the binder used.
  • a temperature control substance such as activated alumina, activated bauxite, or hydrated alumina may be incorporated into cigarette paper in amounts sufficient to control and lower the temperature of the smoke forming zone adjacent the cigarette combustion zone, to minimize the formation of tars and/ or carcinogenic products which may result from combustion of the paper.
  • a temperature control substance such as activated alumina, activated bauxite, or hydrated alumina may be incorporated into cigarette paper in amounts sufficient to control and lower the temperature of the smoke forming zone adjacent the cigarette combustion zone, to minimize the formation of tars and/ or carcinogenic products which may result from combustion of the paper.
  • Such additions of these various types of alumina may be made, for example, at the beater stage before the paper fiber slurry is formed into sheets on the Four-drinier machine.
  • the amounts of alumina added will generally range from about 5 to percent, the amounts added being selected so as to impart to the paper a combustion rate no greater than that of the tobacco-alumina mixture,
  • tobacco combined as described with the hydrous temperature control substances is made into cigarettes using as a Wrapper therefor, cigarette paper which has incorporated therewith an ash strengthening material such as being coated with a thin layer of aluminous metal, or with a layer of aluminum oxide, or a mixture of aluminous metal and oxide (partially oxidized aluminum) on one or both' sides of the paper.
  • an ash strengthening material such as being coated with a thin layer of aluminous metal, or with a layer of aluminum oxide, or a mixture of aluminous metal and oxide (partially oxidized aluminum) on one or both' sides of the paper.
  • Such metal coated cigarette paper may be manufactured by known methods, for example, by deposition of metal on the surface thereof using vacuum metallizing procedures.
  • Regular cigarette paper may be coated on one side in this way using a vacuum below 1 micron pressure with a single flash of aluminum to provide an aluminum metal layer of a thickness between about 3 and millionths of an inch, preferably about 5 to 10 millionths of an inch.
  • the metallization is carried out at low pressures between about 2 and 5 microns, there is formed on the paper a yellowish coating, attributable to the formation of aluminum oxide on the surface of the metal by oxidation due to small amounts of residual oxygen in the vacuum chamber.
  • aluminum oxide is deposited with a light brown to dark violet color.
  • the coating of aluminum oxide or of aluminum metal in combination with the oxide is superior to that of aluminum metal itself insofar as the combustion of the paper is concerned, since the greater the proportion of oxide, the lower is the temperature rise, small under any circumstances, which results from the combustion of the metal.
  • the oxide coating on the paper produces a temperature lowering effect similar to that of the alumina in the tobacco, except that no release of moisture is involved.
  • Cigarettes prepared from the tobacco treated with the temperature control substances of this invention and made into cigarettes using the above coated paper exhibit improved ash retention and ash stability, in that ash and hot particles do not drop off immediately after burning, but remain in place until a substantial length has been formed.
  • This ash strengthening is caused by the burned special cigarette paper leaving an envelope-like outer layer which efiicaciously improves the stability and retention of the ash.
  • a cigarette prepared using tobacco admixed with fluffy alumina as a filler, and aluminized cigarette paper shows especially favorable ash strength.
  • the cigarette paper can also be treated in a solution containing a small percentage of a so-called flame proofing agent, for exarnple, a 1 to 5 percent solution of a sodium bzorophosphate complex known commercially as Abopon (Glycol Products "Compan New York City, United States of America).
  • a flame proofing agent for exarnple, a 1 to 5 percent solution of a sodium bzorophosphate complex known commercially as Abopon (Glycol Products "Compan New York City, United States of America).
  • the envelope is black in color and is capable of retaining ash with hot aluminapanticles until tipped off.
  • the cigarette paper loses some flexibility and may tear during wrapping; accordingly, treatment with a flame proofing agent is preferably carried out after the cigarette is made.
  • hydrous temperature control substances of our invention may be incorporated into cigarette and smoking tobaccos of all types, at any desired stage of processing.
  • the substance may be applied to the leaf prior to cutting, or to shredded tobacco.
  • Our invention is also readily applied to the improvement of so-called reconstituted tobacco, prepared from waste fines, field scrap '(fann damaged leaves), stems, and dust, which are customarily cut or comminuted and formed into sheets with the aid of a suitable binding material, and afterward made into filaments by shredding, or into strips, for the preparation of smokers articles such as cigarettes, cigars, and the like.
  • control substances may also be made into a thin sheet using a suitable binder, and then the sheet shredded into thin individual fibers which may be incorporated into the tobacco.
  • Suitable flavoring materials, humectants, and the like may be admixed with the control substance as well as with the tobacco itself.
  • FIGURE illustrates a cigarette prepared in accordance with this invention.
  • a filter 16 is included in the body of the cigarette.
  • cigarettes of a brand reputably having one of the most eflicien-t filters were purchased on the open market.
  • the filter was broken, the paper split from the tobacco, the tobacco and the filter placed in a king-size hand operated apron cigarette maker.
  • a measured charge of hydrous fiuiiy alumina or hydrous activated alumina was sprinkled evenly over the tobacco and worked into the tobacco with a stylus.
  • a gummed cigarette paper was set into the roller and the cigarette containing the alumina reassembled and marked.
  • Samples were marked A, B, C, D, and E, as follows: A (lib ter), 1 part coarse while hydrous activated alumina to 5 parts tobacco; B (filter), 1 part tinted hydrous flufiy activated alumina to 5 parts tobacco; C (filter), 1 part tinted coarse hydrous activated alumina to 4 parts of tobacco; D (filter), 1 part tinted hydrous fluffy activated alumina to 2 parts of tobacco; and E (filter), commercial cigarette reassembled as above with filter, but with no alumina additive. Three runs were made, for each cigarette.
  • Example 1 There is added to cut cigarette tobacco about 50% by weight of 14 to 28 mesh fiuiiy activated alumina containing about 24% total moisture based on the A1 0 conent. This additive is preferably made to the tobacco in the cigarette machine just prior to the tobacco being formed into a cigarette.
  • Example 2 Tobacco Waste suitable for manufacturing reconstituted tobacco is made into a water slurry which contains a suitable binder and to which is added an amount of alumina trihydrate equivalent to about 25 to 50% of the air dry weight of the tobacco. When air dry, tobacco contains about 12.5% moisture. This slurry is formed into a sheet in accordance with conventional procedures.
  • Example 4 A process for making reconstituted tobacco is set forth in the United States Patent 2,734,510 to G. P. Hungerford et al., which lends itself to carrying out this invention.
  • the process disclosed in this patent broadly comprises forming a wet web from a solution having a film forming material dispersed therein. Dry tobacco dust is applied in a uniform layer to the wet web which is subsequently dried and shredded or cut for use as a tobacco product.
  • the Hungerford process is utilized in carrying out the present invention by applying, in conjunction with the tobacco dust as it is applied to the wet web, alumina trihydrate of 325 mesh size and smaller in an amount such as the air dried reconstituted tobacco will contain from 25 to 50% of the trihydrate.
  • Example 5 The above outlined Hungerford'process can also be utilized in making a flexible Web of the temperature control substance. This is accomplished by dusting hydrous activated alumina in place of the tobacco dust onto the wet web followed by treating the dusted web in accordance with the remaining steps of the Hungerford process. The resultant sheet product is then shredded and added to shredded tobacco in an amount equivalent to a hydrous activated alumina content varying from 25 to 50% by weight of the tobacco.
  • Example 6 Reconstituted tobacco having a temperature control agent such as hydrous activated alumina or alumina trihydrate incorporated therein, as set forth in Examplm 4 and 5, is rolled by conventional methods into a thin sheet suitable for use as a cigarette paper or wrapper.
  • a temperature control agent such as hydrous activated alumina or alumina trihydrate incorporated therein, as set forth in Examplm 4 and 5
  • a cigarette was prepared using ordinary cigarette paper and as a filled tobacco admixed with about 35 percent of hydrous flulry alumina prepared as described above.
  • the effect of the lower smoke forming temperature of the tobacco is demonstrated by laboratory tests in which the cigarette, and an ordinary cigarette were first conditioned at 77 F. and 50% relative humidity, and each was smoked as aforementioned .on a standard smoking machine as described in Industrial and Engineering Chemistry, volume 28, pages 836-839 (1936).
