Description

  TECHNICAL FIELD The present invention relates to a method for producing a regenerated tobacco sheet, specifically to a method for producing a regenerated tobacco sheet containing a flavor compound contained in a gel matrix in the regenerated tobacco sheet, and more specifically to a reproduction containing an alginate compound. The present invention relates to a method for producing a tobacco sheet.

  In the manufacture of smoking articles, especially cigarettes, it is common to use a certain percentage of striped regenerated tobacco in tobacco blends. This regenerated tobacco is usually prepared from tobacco fines, veins, petioles and other tobacco waste, which are further processed, formed into sheets, cut into strips, and blended with fresh chopped tobacco. The amount of reconstituted tobacco used in tobacco blends for smoking articles will vary depending on the smoking article, but is usually less than 20%. Also, the recycled tobacco sheet produced through the papermaking process does not contain additional binders such as alginate, guar gum, xanthan gum, acacia gum, pectin gum, other gums and modified cellulose compounds.

  There is currently a great deal of interest in reducing the ignitability of smoking goods due to the considerable number of fires caused by burning cigarettes coming into contact with flammable or flammable materials. . Accordingly, considerable efforts have been made in the industry to provide low ignitable smoking articles. Most of this is done by modifying the wrapper of the smoking article. In particular, the wrapping for smoking articles is coated or an additive is added to reduce the air permeability of the wrapper or change the chemical properties.

  The object of the present invention is to provide a novel formulation for a regenerated tobacco sheet and a method for its production.

  It is a further object of the present invention to provide a smoking article comprising a novel recycled tobacco sheet in one layer of the smoking article wrapper.

  Another object of the present invention is to provide a novel formulation for a regenerated tobacco sheet having an alginate-based coating and a method for producing the regenerated tobacco sheet.

  It is a further object of the present invention to provide a cigarette that includes a novel recycled tobacco sheet having an alginate-based coating in one layer of the wrapper.

  The present invention provides about 80% or less tobacco, about 80% or less, preferably about 60% or less wood pulp, and about 30% or less, preferably about 20% or less binder (eg, alginate). , Guar gum, xanthan gum, acacia gum, pectin gum, other gums and modified cellulose compounds), and about 30 wt% or less, preferably about 3 to 5 wt% of a flavored tobacco sheet.

  Methods for producing recycled tobacco sheets are known in the art. The present invention provides a method for producing a regenerated tobacco sheet coated with a binder to reduce air permeability and reduces the ignitability and burning rate of the cigarette. The binder may be alginate, guar gum, xanthan gum, acacia gum, pectin gum, other gums and modified cellulose compounds. Recycled tobacco sheets coated with a binder are cut into various lengths having a predetermined width for use in smoking articles. In one aspect, the predetermined width strip is disposed longitudinally of the tobacco rod between the tobacco rod and the outer cigarette wrapper.

  Further objects and advantages of the present invention will become apparent to those skilled in the art in view of the following detailed description, including preparation examples of the regenerated tobacco sheet of the present invention.

  The features and advantages of the present invention shall be understood in the detailed description of the preferred embodiment with reference to the accompanying drawings.

  A cigarette with a modified burn rate is shown in FIG. 1, which may hereinafter be described as a partially double-wrapped cigarette 10. As can be seen, the double wrap cigarette 10 of the present invention includes a standard tobacco column 13 that extends from the exposed end to a filter 15. Enclosing the tobacco column 13 is an outer wrapper made of cigarette paper 12. Disposed on the inner surface of the cigarette paper 12 are separate inner wrapper layers or strips 14a and 14b that partially surround the column. The separate partially surrounding inner wrapper layers 14 a and 14 b act as a burning rate modifier for the tobacco column 13 by altering the burning characteristics of the cigarette 10. As is apparent from the embodiment shown in FIG. 1, the inner wrapper layer may be disposed coaxially with the tobacco column 13 and may extend substantially the entire length of the tobacco column from the exposed end to the filter 15. In this embodiment, by inserting separate partially surrounding inner wrapper layers 14a and 14b that are coaxially disposed on the tobacco column 13, the packing density of the tobacco, the air permeability of the outer wrapper 12, and the outer wrapper. The burning rate of the cigarette can be varied so that the burning rate can be adjusted according to the additive, the width and air permeability of the inner wrapper layers 14a and 14b, the additive to the inner wrapper layers 14a and 14b, etc. . Alternatively, the inner wrapper layer may be shortened so as not to extend over the entire length of the tobacco column 13 or may extend in different directions. Accordingly, it is possible to vary the burning rate of the partially double-wrapped cigarette 10 of the present invention, particularly based on the combination of elements described herein.

  As can also be seen from FIG. 1, the partially double-wrapped cigarette 10 of the present invention having modified burn rate characteristics includes an outer wrapper strip 14a and 14b having first and second partially surrounding inner wrapper strips 14a and 14b. Includes cigarette paper wrapper 12. The outer cigarette paper 12 may be a normal air permeability paper that typically exhibits an air permeability of 15 to 80 CORESTA units. In combination with the outer cigarette paper 12 is located at least one inner wrapper layer that partially surrounds the column that can modify the burning rate characteristics of the cigarette 10. As shown, first and second partially surrounding inner wrapper layers 14a and 14b are provided on opposite sides of the tobacco column 13. In order to provide substantially uniform burn rate characteristics throughout the tobacco column 13, the partially surrounding inner wrapper strips 14 a and 14 b are arranged to extend substantially coaxially with the tobacco column 13 to the filter 15. Is done.

  The partially wrapped inner wrapper strips 14a and 14b as shown in the embodiment of FIG. 2 extend from end to end of the tobacco column 13 and are evenly spaced from each other or to the desired burn rate characteristics. Accordingly, it may be arranged at another position.

  Referring to FIG. 3, it can be seen that the partial double wrap cigarette 10 of the present invention has high diffusion regions 21 and low diffusion regions 22 that are alternately arranged by the arrangement of inner wrapper layers or strips 14a and 14b. is there. As can be seen, the permeability of CO and oxygen increases through the barrier formed by the outer wrapper 12 while maintaining normal smoke deliveries by the at least one high diffusion region 21. In combination with this, the low diffusion region 22 formed by the peripheral regions of the inner wrapper layers 14a and 14b is directly related to the air permeability of the inner wrapper layers 14a and 14b in combination with the outer wrapper 12. Potentially blocking a substantial part or all of the gas flowing in and out therethrough. The co-linear zones of the high diffusion region 21 and the low diffusion region 22 exhibit an air permeability of more than 14 CORESTA units in the case of the high diffusion collinear region and less than 8 CORESTA units in the case of the low diffusion collinear region. The air permeability is shown.

  The cigarette structure with modified burn rate as shown in the figure is a partially double-wrapped cigarette 10 that uses a typical 27 mm wide standard outer cigarette paper 12. In another embodiment shown in FIGS. 2 and 4, inner wrapper layers 14 a and 14 b are disposed along the inside of the outer-wrapped paper 12 separately and partially surrounding the tobacco column, which are substantially the same as the cigarette paper 12. Alternatively, it may extend along the entire length. Although the outer wrapping paper has standard air permeability and structure, the partially wrapped inner wrapper in this embodiment is composed of first and second strips 14a and 14b, each having a width of 4 mm. And has an air permeability of less than 8 CORESTA units. Thus, these two inner wrapper layers 14a and 14b surround approximately 8 mm of the circumference of the partially double-wrapped cigarette 10 of the present invention, but up to 15 mm of the circumference of a standard cigarette tobacco column. You may make it. Any combination of partially wrapped inner wrapper and outer-wrapping paper will function according to the above factors such as the air permeability of each paper, but it will give good burning rate characteristics and influence on smoke characteristics and flavor Therefore, it is desirable to use an inner wrapper that covers less than about 75%, preferably less than 60%, more preferably less than 35% of the circumference of the outer-wrapped paper. This is a function of the entire cigarette and may vary depending on the circumference of the outer paper. However, various changes are possible to achieve the same good results using the inventive concept of the design, and the description relating thereto is exemplary and not limiting of the invention.

  Many different structures may also be utilized to provide the cigarette with the burn rate modified shown herein. A single inner wrapper layer or multiple inner wrapper layers may be provided depending on the desired properties and burning rate. Thus, as described above, a combination of a low air permeability inner wrapper region and a high air permeability outer wrapper region may be utilized to provide the desired various linear burning rates. Thus, the typical linear burn rate of 6.0 mm / min may be reduced to the desired burn rate by a combination of the air permeability of the inner wrapper strip that partially surrounds the outer wrapper, among other factors. If necessary, it can be easily reduced to less than 4 mm / min. This replaces a low air permeability single inner wrapper strip formulation or inner wrapper strip with various structural materials such as recycled tobacco, low air permeability paper, polymeric materials, other papers or materials Including. The inner wrapper strip is coated with a binder such as alginate (eg sodium alginate), guar, xanthan, acacia, pectin, other gums, modified cellulose compounds or hydrocolloid compounds, which function as combustion modifiers or inhibitors And forming at least one low diffusion region along the tobacco column. These binders reduce the air permeability of recycled tobacco sheets used as inner wrapper strip, outer wrapper air permeability, tobacco packing density, inner wrapper strip burning characteristics, inner wrapper air permeability and others The combination of all of these elements provides the appropriate properties so that the cigarette provides the desired burning rate.

  As shown in FIGS. 4 to 7, various aspects can be used to obtain a low air permeability region. A plurality of inner wrappers or inner strips 16a, 16b, 16c and 16d are arranged in a standard outer wrapper 12 in an open state as shown in FIG. These strips may be evenly spaced along the interior of the outer wrapper 12 or spaced apart from the seam where the outer wrapper is wound and bonded in the garniture of the cigarette making machine. May be. The strips 16a-16d may all be fed into the garniture and are incorporated inside the outer wrapper adjacent to the tobacco column. By placing an inner alginate-coated inner wrapper strip that partially surrounds the tobacco column, the burning rate is significantly reduced to significantly reduce static burning rate or self-extinguish at desired intervals So that the burning rate can be modified to a desired level.

  As shown in FIG. 5, the inner wrapper 17 having a non-linear side compared to the edge of the outer wrapper 12 is used as a partially enclosing inner wrapper to form a low air permeability region. It is also possible. As illustrated, the inner wrapper 17 has a corrugated shape, whereby the position of the low air permeability region changes at a position along the tobacco column axis. This non-linear arrangement of the low air permeability region allows the cigarette to take a different arrangement during static combustion, ensuring the desired static burning rate regardless of cigarette placement. To cause.

  FIG. 6 shows another embodiment of the cigarette with a modified burning rate according to the present invention. As can be seen from the figure, the high diffusion region 21 and the low diffusion region 22 are formed by a partial double inner wrapper 18 surrounding a part of the tobacco column 13 inside the outer wrapper 12. As shown in FIG. 6, the double inner wrapper 18 extends almost half way around the tobacco column 13. However, many different structures can be utilized to achieve a suitable linear burning rate. The double inner wrapper 18 may be composed of standard cigarette paper having a low air permeability of less than 7 CORESTA units or cigarette paper coated with a burning rate modifier, or usually less than 5, preferably It may be composed of a regenerated tobacco sheet having a low CORESTA unit value of less than 3 with or without additives. A secondary advantage of using recycled tobacco sheets as the double inner wrapper 18 is that the inner wrapper color is similar to the tobacco column 13 and is whitened in contrast to the column color. This means that the region is not formed along the low diffusion region 22. A polymer film or other material can also be used as the double inner wrapper 18. The double inner wrapper shown in FIG. 6 has a width of 2-14 mm to obtain the desired suitable burn rate modification with a sufficiently low linear burn rate, preferably 4.0 mm / min, Alternatively, it is preferable to be less than 75% of the outer wrapper.

  Although another embodiment is shown in FIG. 7, a plurality of inner wrapper strips 19 are used in this embodiment and substantially enclose the tobacco column 13 within the outer wrapper 12. The plurality of inner wrapper strips 19 are fed into a garniture adjacent to the outer wrapper 12 and surround the column as the tobacco column 13 is formed in the cigarette maker. The plurality of strips 19 may be composed of low-permeability cigarette paper that is individually fed into the cigarette making machine, or fed into the cigarette making machine adjacent to the garniture and cut to the appropriate strip width. It may be composed of a single or a plurality of strips. As shown in FIG. 7, a plurality of inner wrapper strips 19 are used and extend substantially coaxially along the length of the tobacco column 13. The strips 19 preferably extend over the entire length of the tobacco column, for example, to modify the burning rate along the entire tobacco column regardless of cigarette placement. By providing a plurality of strips 19 as shown in FIG. 7, the degree of modification of the burning rate of the cigarette is increased.

  Inner wrappers coaxially extending substantially along the length of the tobacco column 13 provide a significant advantage over the length of the tobacco column over rings alternately disposed perpendicular to the axis of the tobacco column 13. Such vertical rings, which are alternately positioned, cause the tobacco column 13 to burn non-linearly. In such designs where a ring surrounding the tobacco column is provided, the paper burn-through at the point where the ring is located, as opposed to the unadjusted paper air permeability between the rings. It varies between low line burn rate and high line burn rate depending on the temperament. Such a non-linear burning rate is such that a continuous free burning of tobacco for a considerable time between the rings does not provide a suitable burning rate modification over the entire length of the tobacco column. Is not desirable. In addition, smokers may inhale as tobacco column fire passes through the low air permeability ring at the point where a low air permeability ring exists. At such points, cigarette smoke delivery changes, such as a significant increase in carbon monoxide and other compounds that are generated when tobacco fire passes through one of several rings. . Thus, the partially double-wrapped inner wrapper layers of the present invention provide these by modifying the burning rate along the entire coaxial length while providing a known standard delivery rate over the entire length of the tobacco column. The problem is solved.

  In the cigarette 10 with a modified burning rate according to the present invention, it is preferable to incorporate the inner wrapper layer away from the seam regardless of the use of a plurality or a single inner wrapper layer. As is known in the manufacture of cigarettes, the seam 23 is formed by a cigarette making machine by overlapping the side edges 24 of the outer wrapper 12, as shown in FIG. In normal cigarette manufacture, the outer wrapper is folded and glue is applied along either edge 24 before forming the tobacco column 13. During the manufacture of the cigarette 10 with modified burn rate of the present invention, the outer wrapper 12 is properly formed so that the inner wrapper layer does not interfere with the formation of the tobacco column or adhesion of the outer wrapper. It is desirable to keep the wrapper layer separate. Thus, as shown in all embodiments, the inner wrapper layer does not hit the seam of the outer wrapper 12 or interfere with the formation of the tobacco column within the garniture of a normal cigarette making machine. , Arranged away from the side edge 24. Thus, the modified cigarette speed of the present invention can be made on a standard cigarette making machine with a slight modification to the paper feeder, and therefore no changes are required in the garniture. Also, in any of the embodiments shown here, the inner wrapper strip may be placed on the outside of the cigarette and glued or other means outward to form the same linear region of low and high air permeability. It may be held by a wrapper.

  The cigarette with a modified burning rate according to the present invention can be designed by changing the characteristics of the outer wrapper and the inner wrapper. As mentioned above, standard outer wrappers are designed to have a width of 27 mm when unfolded and an air permeability of typically 15 to 80 CORESTA units. As is generally understood, reducing the air permeability of the outer wrapper significantly changes the cigarette smoke delivery rate and linear burn rate. The standard or typical cigarette burning rate can be modified by adding an inner wrapper partially to the cigarette. This inner wrapper may be used alone, or multiple inner wrappers may be used as shown in some of the drawings. This inner wrapper is a paper having the characteristic that the air permeability is significantly reduced to show an air permeability of less than 8 CORESTA units. When the inner wrapper strip is used alone, the inner wrapper having a width of 2 to 15 mm is used. The air permeability of the inner wrapper may be adjusted in the range of 0 to 8 CORESTA units.

  The invention should be more specifically understood by considering the following examples. However, it should be understood that these examples do not limit the invention.

  Several product samples having the structure of a cigarette partially with an inner wrapper strip were produced using the techniques and structures of the present invention described herein. A control cigarette that does not have such an inner wrapper strip and exhibits a linear burning rate of 4.3 to 4.7 mm / min was also used. Different materials were used for the inner wrapper strip, such as standard processed paper and band cast tobacco material as specifically shown in the table below.

Example of a cigarette with two band cast wrapper strips having an air permeability of less than 5 CORESTA units

Example of a cigarette with two cigarette paper strips treated or coated with sodium alginate having an inner wrapper air permeability of less than 5 CORESTA units

Smoke delivery details of two samples with band cast strips

  As is apparent in the examples shown here, the addition of a partial inner wrapper to the cigarette had a significant effect on linear burning rate and self-extinguishing compared to the control cigarette. It was confirmed that the linear burning rate of the cigarette of the present invention was directly affected and the linear burning rate was reduced by a maximum of 40%. All test samples were self-extinguishing when using an inner wrapper with a width of at least 4 mm. Narrower width wrappers will give different results, such as those obtained by using different additives or increasing the number of wrappers. Ten-layer cigarette autolysis is associated with the NIST test, which evaluates the ignitability of cigarettes.

  Smoking articles including recycled tobacco strips

  Another inner wrapper strip 14 that partially surrounds the tobacco column may be a regenerated tobacco strip made according to a specific formulation and method described below. The outer cigarette paper 12 may be a paper having a normal air permeability indicating a normal air permeability of 15 to 80 CORESTA units. Two strips 14 of regenerated tobacco sheets were provided on opposite sides of the tobacco column 13 to form a partially surrounding inner wrapper layer. The partially surrounding inner wrapper layer 14 containing the regenerated tobacco strip may extend coaxially with the tobacco column substantially along the length of the tobacco column 13. In one aspect, the strips are spaced apart from one another so that the resulting cigarette burns uniformly.

  Preparation of recycled tobacco sheet with binder

  FIG. 8 is a flowchart illustrating a regenerated tobacco modification step for producing a cut inner wrapper. In the preparation of regenerated tobacco for use in cigarettes, tobacco particles such as tobacco fines, petiole, scraps, cut leaf blades, chopped stems or combinations thereof are added to 11-20 parts of aqueous solvent to 1 part of tobacco. Slurry in conditioned aqueous solution. The solution is extracted for 30 minutes at a temperature of 160 ° F. The solution is separated into an extract containing a water soluble compound and a solid / fiber portion using known separation techniques such as centrifugation or filtration. 10% wood pulp made from xylem fibers refined into solid / fiber parts and made into pulp, alginate (eg sodium alginate), guar, xanthan, acacia, pectin, other gums, modified cellulose compounds and This solid / fiber tobacco, wood pulp and optional second binder mixture, which is mixed with an optional second binder, such as a hydrocolloid-based compound, is formed into a recycled tobacco sheet by known papermaking processes.

  Meanwhile, the extract can optionally be treated with a specific adsorbent to selectively remove unwanted components. The extract is then centrifuged to discard the adsorbent containing undesirable components. The extract is then concentrated. A first binder such as alginate (eg sodium alginate), guar, xanthan, acacia, pectin, other gums, modified cellulose compounds and hydrocolloid compounds is added to the extract. Wetting agents such as glycerin can also be added to improve sheet lamination, which is usually added before the binder and any additional flavoring. Desired flavors can also be added to the extract.

  This new extract mixture is applied to a pre-formed tobacco sheet. Alternatively, a third binder mixed solution such as alginate (eg, sodium alginate), guar, xanthan, acacia, pectin, other gums, modified cellulose compounds and hydrocolloid compounds may be size pressed and / or sprayed onto the regenerated tobacco sheet. it can. The regenerated tobacco sheet is dried, cut into long strips having a desired width, and wound on a bobbin. This elongated strip can be used as a strip extending longitudinally along the outer periphery of the tobacco rod and the inner surface of the outer wrapper.

  Preferred mixtures are about 80% or less tobacco, wood pulp or less, preferably about 60% or less, preferably about 60% or less, binder about 30% or less, preferably about 20% or less, and flavoring is added. About 30% by weight, preferably about 3 to 5% by weight.

  The following example illustrates the process after preparation of a regenerated tobacco sheet having a binder for use in smoking articles.

  500 pounds of tobacco and wood pulp (in a ratio of 1: 3 to 3: 1) in the process of making recycled tobacco sheets in a mixing vessel with 750 gallons of water at 140 ° C. to 190 ° C. for 30 to 45 minutes Extracted. After extraction, the mixture was separated into a solid (fiber) and liquid (extract) stream by centrifugation, filtration or pressing.

  The liquid extract was concentrated by vacuum evaporation and mixed thoroughly with 60 pounds of glycerin. An alginate solution was prepared in a separate container with thorough dispersion of 40 pounds of sodium alginate in 135 gallons of water. The extract concentrated with glycerin was thoroughly mixed with the alginate solution. 75 pounds of powdered solid adsorbent, such as bentonite (diatomaceous earth), carbon, cyclodextrin, cellulose acetate, or combinations thereof, to optionally and selectively remove nitrogen and other undesirable compounds Stir slowly for 20-45 minutes. After stirring, the adsorbent was separated from the extract by centrifugation and discarded. The extract was then concentrated and treated with glycerin and alginate as described above.

  Meanwhile, the solid stream was passed through a refiner to fibrillate the fibers into tobacco-wood pulp. The pulp was then used to make a base sheet on a long paper machine and dried. Either of the two concentrated extracts prepared above was added again to the base sheet by size press or spray. The resulting sheet was finally dried, cut into strips and wrapped around a bobbin for use as an inner wrapper.

  A sheet was prepared and cut as in Example 2, except that the alginate solution was added directly to the base sheet instead of mixing with the concentrated extract. Also, 25 pounds of precipitated chalk or chitosan (inorganic or organic inert filler) was added to the refined pulp mixture before making it into a base sheet on a long paper machine. Other fillers include combinations of liposan and chalk, chitosan and liposan.
