Definitions

  • ABSTRACT A cigarette wrapper comprising a microporous sheet formed from a cellulose derivative binder filled with finely ground paper.
  • the wrapper also includes a small amount of potassium nitrate.
  • Such cigarette wrappers are effective to selectively reduce the nicotine delivery from normal cigarette tobacco blends.
  • the present invention pertains to porous thermoplastic cigarette wrappers which are'effective to selectively reduce the nicotine delivery from normal cigarette tobaccos. More specifically, the present invention pertains to cigarette 'wrapper's comprising a cellulosic binder filled with finely ground paper and a smallamountof potassium nitrate. The filler may also include awhiten er. The present invention also pertains to a smoking article comprising a 'smokeable material contained within the thermoplastic wrapper.
  • the cigarette wrapper of the present invention provides means for selectively reducing nicotine delivery.
  • Tobacco foils prepared from cellulose derivative binders filled with, finely ground tobacco are well known in the art.
  • U.S. Pat. .Nos. 1,716,250; 2,485,670; 2,598,680; 2,706,695; 2,830,597; 2,893,400; 2,897,103; 2,927,588; 2,955,601; 3,062,688; 3,288,148; and 3,343,546 all disclose tobacco foils prepared from finely ground tobacco dispersed in a matrix of-a cellulosic binder.
  • Typical binders include cellulose esters or cellulose ethers such as methyl cellulose, carboxymethyl cellulose, or cellulose acetate.
  • such tobacco foils are disclosed as useful as cigar wrappers.
  • foils prepared from cellulose derivative binders filled with ground tobacco have also been proposed as cigarette wrappers. See German. Offen. 2,008,150.
  • US. Pat. No. 3,699,972 discloses the use 'ofc ombustion-accelerating agents, such'as potassium nitrate, to treat preselected areas of cigarette wrappers'The combustion-accelerating agents cause the treated area of a cigarette wrapper to burn more rapidly than untreated surrounding areas so that increased air flow i's'obtained through the rapid burning areas. While such wrappers are effective to reduce tar and nicotine deliveries, SuCh' wrappers do not'result in selective "nicotine delivery re-' duction.
  • thermoplastic wrappers of the present invention provide a method of selectively reducing the nicotine delivery from normal cigarette tobacco' blends.'ln addition, unlike tobacco filled wrappers, the thermoplastic wrappers of the present invention do not impart a heavy, sour-sweet, or stemmy off-taste to cigarette tobacco smoke.
  • the present invention also contemplates a smoking article 'comprising a smokeable material contained within a cigarette wrapper produced from the above described thin porous thermoplastic sheet.
  • the type of paper used as a filler in the thermoplastic wrapper of the present invention is not critical. Unfilled flax paper is preferred. Such papers are commerically available and commonly used as plug wraps in the cigarette industry.
  • the paper preferably is ground to a size of mesh or less to insure that it may readily dispersed in the binder.
  • the wrapper contains between about 2O percent and about 30 percent by weight finely divided pulverized paper.
  • thermoplastic wrapper m'ay'optionally include additional fillers to enhance the whiteness of thesheet.
  • additional fillers which enhance whiteness is not necessary.
  • a white wrapper is desirable to achieve consumer acceptancesuitable whiteners includecalcium carbonate, magnesium carbonate,- aluminum hydroxide, talc, and titanium dioxide. Titanium dioxide, .well known as a white pigment, is the preferred whitener.
  • whiteners are, included in the wrapper formulation, they maybe added in amounts up to about 40 per.- cent by weight, and preferably in ,amounts of from about percent to. about 30 percent by weight.
  • the wrappers of the present invention may also include minor amounts of additional fillers, spch as pow-. dered charcoal or powdered alumina. Such fillers may replace part of the finely divided pulverized paper but should not encompass more than about percent by weight of the composition. Largeramounts, should not be employed, as these relatively dense materialsprocess poorly and give a less porous sheet.
  • potassium nitrate acts as a burn accelerator, thereby controlling the puff number of, and reducing delivery of tar from, cigarettes employing the wrapper.
  • Amounts of potassium nitrate greaterthan about 2.8 percent by weight should not be employed. Since the KNO strongly influences the cigarette free'burn rate, larger amounts cause the cigarette to burn too rapidly. At least about 1.5 percent by weightpotassium nitrate should be included in the wrapper formulation to achieve a desired burn 'rate and the beneficial enhanced selective nicotine reduction effect. Preferably, the potassium. nitrate is employed in amounts of from about 1.7 percent to about 2.5 percent by weight.
  • Oxidizers other than potassium nitrate such as potassium chlorate sodium chlorate, calcium peroxide and colloidion (cellulose nitrate), are not suitable. When such oxidizers are used in place of potassium nitrate the wrapper becomes too flammable and tends to flame rather than smolder. In addition, such oxidizers are relatively ineffective with respect to controling burn-rate.
  • the thin porous sheet of the present invention would normally. include at least about 20 percent by weight of a thermoplastic binder. Lesser amounts. of binder are not sufficient to give the sheet adequate integrity. Normally, the sheet would not include more than about 55 percent by weight binder, as larger amounts adversely affect burning characteristics. Preferably, the sheet contains from about 'percent to about 40 percent by weight thermoplastic binder.
  • lulose derivatives include various cellulose esters and cellulose ethers, such as methyl cellulose, carboxymethylcellu lose, hydroxyethyl cellulose,.ethyl cellulose. cellulose acetate, etc.
  • preferred binder comprisesa mixt'ureof. methyl cellulose and cellulose ace-- tate. Mixtures in which. the cellulose acetate and.
  • methyl cellulose are presentin ratios offrom 2:1 'to' 20:! parts by weight are particularly preferred.
  • Suitable cellulose derivatives should-have a sufficient yield, at relatively low-concentrations, relativelyhigh viscosity solutions.
  • the cellulose derivatives should have a degree of polymerization such that they are capable of forming a coherent, tough sheet or mass when the aqueous or organic solvent is evaporated.
  • the degree of substitution refers to the average number of hydroxyl groups (out if thetotal of three groups) of each glucose unit of the cellulose polymer chain which have had the hydroxyl groups converted to either ester or ether radicals. For example, with respect to methylcellulose, at least 1.6 of the three hydroxyl groups perpoly mer unit must be converted to methoxy groups before the polymer will become water soluble.
  • Methyl cellulose having a degree of substitution greater than 2.0- is decreasingly soluble in water and increasingly soluble in non-polar solvents.
  • Methyl cellulose having a degree of substitution of between about 1.6 and 2.0 is water soluble and also soluble in slightly polar organic solvents.
  • a plasticizer may be included in the wrapper formulation. Any of thenumerous well known plasticizers suitable for use'with cellulose derivatives may be employed. Specific examples of suitable plastici'zers'are l,3-butylene glycol, propylene glycol, glycerin, butylene glycol, triethylene glycol, etc.
  • a pre ferred plasticizer is a mixture of 1,3-butylene glycol, propylene glycol and glycerin.
  • the wrappers of the present invention may be prepared by adding the binder to the suitable solvent: to produce a swollen, gummy mass.
  • any number of a wide'variet'y of solvents may be employed.
  • Ground paper is mixed into this mass along with potassium nitrate and, if'desired, a whitener such as titanium dioxide. Additional solvent maybe ad'd'edto the resultant mixture to produce a free flowing slurry.
  • 'lf plasticizers are desired, they may be added to the freeflo wing slurry.
  • the slurry is cast into sheets and dried to removesolvents. The cast sheets should be dried slowly and'at relatively low temperatures so that microporous sheets are produced. lf drying-is effected at a temperature greater than about C; non-porous 'sheets' may result.
  • Sheets produced according to such' a technique are particularly suitable for use-as cigarette wrappers if process conditions are regulated to attain a thickness which approaches that of conventional cigarette paper.
  • the thickness of the sheet should be such that it is no more than fivetimesheavier than conventional-cigarette paper.
  • the processing technique also should becontrolled so thatthe resultant sheet'has a microporous structure to give a porosity of between about 5 and'6O Greiner,
  • microporous refers to a sheet in which a majority- (greater than. 50 percent of the pores have a diameter of 3-microns-or less; A porosity within these parameters is importantv with respect to obtaining the properties desired-in a cigarette wrapper, including se lective nicotine reduction.
  • Porosity can be controlled within these limits by removing solvent from the cast sheet relatively slowly at relatively low temperatures.(e.g., below 8C.). Specific solvent techniques to achieve the desired porosity depend upon the particularly solvent system employed. Preferably, binders and solvent systems are selected so that drying does not require the use of subatmospheric pressure. a y
  • 26.8 parts by weight titanium dioxide (National Lead Co. Titanox A WD) is added 'to the swollen gummy mass. The titanium dioxide thins the mixture slightly.
  • 26.8 parts by weight paper (Ecusta E-592) which has previously been ground in a Wiley mill and screened to a size less than 140' mesh, is then added to the mixture.
  • Example 2 Cigarette Preparation-andSmoke Analysis Sheets made in accordance with” Example I were cut into 90 X 29 mm sections'and cigarettes were prepared using these section as wrappers.- Each'cigarette approximately 850 mg. of a commerical cigarette tobacco blend and had a 21 mm. cellulose acetate filter affixed atoneend.

  • thermoplastic wrappers are effective to selectively reduce nicotine delivery. Relative to the control, allof the thermoplastic wrappers (Samples B. C. and D) resulted in a significant increase in the tar/nicotine ratio. Thus, it is apparent that the wrappers selectively reduced nicotine delivery relative to tar delivery.
  • the slurry is cast onto a stainless steel sheet using a standard laboratory TLC spreader.
  • the spreader is set for a 1.0 mm thickness sheet.
  • thermoplastic sheet may be stripped from the stainless steel sheet.
  • the resultant sheet has a color very close to that of normal cigarette paper with a smooth almost soft hand.
  • Cigarettes'pre'pared from wrappers produced in accordance with Examplel were also smoked by smokers. Subjectively, the smokers found the paper filled thermoplastic wrap to be free of the heavy stemmy offitaste which is obtained from cigarettes prepared from tobacco filled thermoplastic wrappers. The cigarettes prepared from wrappers produced in accordance with Example 1 also gave a uniform char line and a white ash similar to conventional cigarette paper.
  • EXAMPLE 4 To illustrate the potassium nitrate is not effective to selectively reduce nicotine when applied to conventional cigarette paper, a cigarette paper was treated so that it contained about 1.0 percent by weight potassium nitrate. Cigarettes were prepared from this treated paper, as well as from conventional cigarette paper which contains about 1 percent potassium citrate.
