Description

[Detailed description of the invention] How to process cigarette paper Technical field The present invention makes cigarette paper fireproof and allows sidestream smoke, i.e. tobacco, to be effectively smoked. and how to reduce the amount of smoke emitted when the smoke is not being used.

3”1ΩJl Treating the cigarette paper and/or tobacco to make it fire resistant and reduce side-stream smoke Existing methods suffer from one or more of the following problems: This processing method has many It may produce a dark ash that is unacceptable to smokers. Also in other cases This processing method leaves cigarettes with an appearance that is considered unacceptable by smokers. give to

It is an object of the present invention to not adversely affect the desirability of cigarettes to smokers. Reduce sidestream smoke from cigarettes by simple and inexpensive means and methods such as It is to be.

Another object of the present invention is to make it easy and inexpensive to use fire-resistant cigarettes. An object of the present invention is to provide a fire-resistant cigarette that avoids the undesirable characteristics of cigarettes.

Another object of the invention is to provide, by a relatively simple and inexpensive method, i.e. by the use of cigarette paper with a specific filler content and porosity, or The treatment of cigarette paper containing specially selected hygrochemicals provides fire resistance and side-stream smoke protection. It is possible to do both. while maintaining light-colored cigarette ash content. It is also an object of the present invention to provide flammability and/or sidestream smoke reduction. In addition to the present invention The purpose of this is to improve fire resistance and/or reduce sidestream smoke without compromising the appearance of the cigarette. It is about realizing it. Furthermore, another object of the present invention is to eliminate the generation of excessive fine particles 2 in mainstream smoke. without affecting the smoking properties of a single cigarette (fire resistance and/or Or sidestream smoke reduction? It is about achieving. Generally the most cigarette smoker cigarettes with fire resistance and/or sidestream smoke reduction that are acceptable in all respects. It is to manifest.

It is easy and inexpensive to implement, and our U.S. Patent No. 3,050,965 , No. 3.183,914, No. 3.220.418, No. 4.044,778 , 4,146.040 and 4,187,862. Achieving one or more of the objectives stated in 1MU by a non-alkaline process It is also an object of the present invention.

Preferred cigarettes according to the invention with respect to fire resistance and sidestream smoke reduction are FJSO Greiner poro-sity of more than seconds and about 10~ 1 cigarette wrapped in a wrapper of cigarette paper having a weight of 55 jj/m2 It consists of a charge of minutes. Cigarette paper contains substantially no combustion promoters other than fillers. It has a low filler content in the range of about 15 to 22 fillers. Above-mentioned requirements: sound groove cross-winding Tobacco paper has traditionally been used to wrap cigarette filters. but, It is clear that such paper was never used as a consumable wrapper for cigarettes. won. Low porosity cigarette paper provides benefits other than reduction of particulate matter in the side stream. It has been discovered that all of the above objectives are met. Furthermore, we will discuss this in detail below. Sea urchin, paper in water, ethyl alcohol, or one type of substance that linearly decreases burning rate Low porosity, low filler content by IV treatment in solution or suspension It has been discovered that the performance of paper can be further improved.

In addition, a special nari lath combustion rate reducing substance was used to treat regular cigarette paper. It has also been discovered that in one case all of the above objectives of the invention can be achieved. this special Substances that reduce the burning rate of Riras include lactic acid, citric acid, magnesium citrate, and acetic acid. Contains magnesium, tartaric acid, acetic acid, skim milk, skim milk and sugar.

Treating only a portion of this cigarette paper improves fire resistance and/or sidestream smoke reduction. achieved in mainstream smoke from cigarettes with wrappers that have undergone full-area sound treatment. produces significantly less particulate matter than is present in the

Sugar can also be used as a burn rate reducer, but when used in high concentrations When cigarette paper is exposed to heat, it tends to darken. However, brown For the treatment of cigarette paper, even fairly high concentrations of sugar are perfectly acceptable.

Other objects and advantages of the present invention will become apparent from the following detailed description.

detailed description For the purposes of this description and claims, the following definition will be used: “cigarette paper” is a highly refined submersible material that is substantially free of pinholes and substantially free of sizing. Defined as tissue paper made from hemp pulp stock.

"Edge-shaped burning rate reducing substance" is a substance that reduces the burning rate when applied to one roll of cigarette paper and dried. A substance that causes tobacco paper to exhibit a lower static burn rate than the same paper in its untreated state means. Such substances include citric acid, magnesium citrate, and magnesium acetate. nesium, ammonium phosphate, trisodium phosphate, alumina gel, tetraboron sodium hydroxide, ammonium hydroxide, nickel acetate.

Potato starch, sugar, aluminum stearate, manganese sulfate, ammonium sulfate ammonium sulfaminate, aluminum sulfate, acetic acid, lactic acid, and I have fatty milk. Containing sugars such as dextrose, maltose, sucrose, etc. Many materials also exhibit properties as linear burning rate reducing materials. Burning rate reducing substances are All materials have a variety of characteristics, but all have low porosity and low filler content for cigarettes. Can be applied to paper. However, 1. Ordinary cigarette paper contains certain groups of combustible substances. Only velocity reducing material is applied. Specific groups that have been shown to give good results The substances in the loop are citric acid, magnesium citrate, magnesium acetate, and tartaric acid. , acetic acid, lactic acid, skim milk, maltose, dextrose, sucrose lactose, 7-lactose and lactose.

"Filler" is a carbonate compound used in the cigarette industry to promote the combustion of paper. means lucium (CaCO) or other substances. MgCO3 and MgO has been used so far. This is an example of a filler other than CaCO3.

``Breina Hole'' is a cigarette paper hole used throughout the cigarette industry. It is a measure of degree. This means that a specific amount of air passes through a specific area of paper under a specific pressure. Means the time (seconds) required for. The higher the Breiner number, the more porosity the paper has. low (naru)

"Sidestream smoke" is the smoke emitted from a cigarette between puffs. This smoke is tobacco It does not pass through rods or filters and is particularly unpleasant to non-smokers. Ru. In the sidestream smoke test.

Light a cigarette, inhale, hold for 1 minute without inhaling, and then inhale again.

Next, place this rolled cigarette in a wide-mouthed glass jar with a diameter of 5 inches and a height that is the opposite of a wide-mouthed one. Assess sidestream smoke by placing the jar under a jar and visually observing the amount of smoke in the jar.

"Tar" means the liquid product of tobacco combustion, and is Coloring the edges? Evaluate by observing.

"Drying" means drying, by the use of heat, by the use of air movement, simply under ambient conditions. moisture or by evaporation or by some other suitable means. means to remove liquid substances. However, "drying" means the removal of all moisture. It's not about doing it. Rather, in the following description, "drying" refers to the processing of cigarette paper. Afterwards, the moisture and heat are removed to such an extent that each roll of cigarette paper has substantially the same moisture content χ as before treatment. It means begging to leave.

The fire resistance test described here refers to the flammability of pine tress and pine tress (rad). This is a test described in the U.S. Federal Commerce Commission standard (FF 4-7). 2), (16C, FJ, 1652).

This Federal Commerce Commission test uses regular pine tress to test pine tress. It means to do something. However, this test is not suitable for cigarettes using standard pine tresses. Equally applicable to the test, this test using a test sound against a standard pine tress The fire resistance of the cigarettes described in the Examples was measured. Rolling tape manufactured by the present invention The pine tress material used for the test used to measure the fire resistance of Bako was cotton-filled vinyl cotton. It is covered with a futon side material.

After the baking time, spread one roll of tobacco paper evenly on the futon side of the pine tress. and place it horizontally. Let the cigarette burn until it naturally extinguishes before it is completely combusted. Let it bake. If self extinguished, relight the cigarette and retest. rolled taba The entire length of the seven pieces will be burned and the fire will naturally extinguish. Observing rolled cigarette Z, one rolled cigarette It was determined whether the test pine tress caused smoke or ignition. Report on examples The tests used to measure the fire resistance and other parameters reported were made on factory-type equipment. Guaranteed to have the same uniform tobacco packing density as manufactured or factory-made cigarettes. The tests were carried out on homemade cigarettes using careful controls. .

The cigarette according to the invention must meet a specific reference tone groove regarding combustion characteristics. stomach. The cigarette must burn for at least one minute between puffs. linear combustion The speed should be between about 1 and 6 hours/minute. In addition, the processed normal wrapper In the case of a cigarette according to the invention having a A corresponding cigarette but with the same treatment wrapper as the cigarette with 2 treated wrappers. It must be substantially lower than the burn rate of vaco. For example, untreated rolled tobacco If the water treatment wrapper has a burning speed of 5 mm/min, the corresponding winding Cigarettes have a burning rate of substantially less than 5 u/min, e.g. 4+ u/min. must be treated thoroughly.

Treated cigarettes generally show sidestream smoke reduction at burn rates below 6 rounds/min. , some of these cigarettes have burn rates ranging from 1 to 6 I+1 Ill/min. It also shows fire resistance, but other cigarettes need 3.5 to have sufficient fire resistance. It must be processed to have a low burning rate χ of the order of y,*/min.

An important step of the invention is relatively low filling! , l) low porosity cigarettes having a content χ Concerning the use of paper.

Typical cigarette wrappers have a Blaine porosity in the range of about 10 to 40 seconds and a Filler content ranging from 2 to 55 parts (usually calcium carbonate, magnesium carbonate or preferred cigarettes according to this stage of the invention has a Breiner porosity of greater than about 50 seconds and a filler content in the range of about 15 to 22 mm. Latsuha is begging for help. The weight of this cigarette paper is the same as that of regular cigarette paper. Similarly, it should be between about 10 and 55 g/d. A code with these characteristics The type of wrapping paper is a so-called "guragurububu", which is a wrapper for a single-roll cigarette filter. However, it was not used as a cigarette wrapper.

Cigarettes with wrappers made of such paper have excellent fire resistance.

This cigarette produced a slight charcoal ratio when dropped onto a test pine tress. , will eventually extinguish on its own without starting to smoke or ignite.

In all of the following examples, unless otherwise specified, the test cigarettes were approximately 25% A "Winston-Lite" king-sized cigarette with the average circumference of the city. Ta.

Next implementation of cigarettes using low porosity paper Tobacco and lacquer removed from the tar plug, low porosity around this filter Roll paper to form a tube.

Close the edges of the tube and carefully refill the tube with the tobacco to make a single cigarette. The test cigarettes were manufactured in such a way as to ensure the same uniform tobacco density as the tobacco. rolling paper If chemically treated, the tobacco was treated before being returned.

The following four examples are from cigarettes wrapped with low density, low filler content cigarette paper. ``Winston-Wright'' king size cigarettes. each The weight stated in the examples is the weight of the paper containing the calcium carbonate filler (!i/m ') Y means. Porosity is the Breyner number (seconds).

Example 1 Weight = 27g/m’ CaC0,=18.5% Porosity = 50 seconds Example 2 Weight = 559/m CaC0,=20.0% Porosity = 50 seconds Example *Amount = 24g/m CaC0,=20% Porosity = 50 seconds Example 4 Weight = 24g/rrt CaCO3 = 22% Porosity = 50 seconds When the cigarettes manufactured according to all of the above examples were subjected to the above fire resistance test, exhibits substantially improved fire resistance. However, these cigarettes do not absorb sidestream smoke. Shows no substantial reduction.

The lower calcium carbonate content of Example 1 compared to Examples 2, 5, and 4 It resulted in a slightly lower coal f degree Z. The weight of the wrapping paper has little effect on the performance of the wrapping paper. I found out that it doesn't. When the calcium carbonate content of the rolling paper is approximately 15% or less A cigarette does not burn for one minute. Must burn for at least 1 minute under static conditions. This is an essential standard condition for good quality cigarettes. Calcium carbonate content in this low porosity wrapping paper substantially exceeds 22%.

The fire resistance of the wrapping paper is impaired.

The cigarettes according to Examples 1 to 4 are a combination of these new cigarettes and conventional cigarettes. The only difference between cigarettes and cigarettes is the nature of the paper used to roll them (1) compared to regular cigarettes. It can be easily manufactured using a tobacco making machine.

Cigarettes with low filler content and low porosity wrappers have lower filler content than regular cigarettes. The advantage is that because it burns slowly, less cigarette consumption is consumed during the same number of puffs. difference It has more. Whether or not there are direct health benefits from this reduction in the rate of tobacco wasting. It is still unclear. However, due to the reduction in tobacco consumption, a certain length of tack How much tobacco do you use while smoking? Reduced and more effective long filters can be used become.

Is the use of low filler content, low porosity paper fire resistant? Although it is improved, it has almost no effect on sidestream smoke generation. I won't give you any complaints. However, according to the present invention.

Low Porosity 2 Paper with low filler content is treated with water or ethyl alcohol and then dried. It is a simple matter to reduce side-stream blast noise to very low levels by Ru. A cigarette treated in this way produces a small amount of smoke (burns for 1 minute, F Combustion reference sound required in terms of having a linear combustion rate in the range of J1-6rnx/min It's grooved.

Treatment of cigarette paper with water or ethyl alcohol Paste it on the top and bottom of the glass and place it in a water or alcohol bath, then lead it to a dryer to remove excess Remove the moisture or liquid content to reduce the moisture content of a cigarette paper to approximately the light level. This can be easily implemented by reverting to

The following two examples relate to the treatment of low porosity tobacco paper with water or ethyl alcohol. do.

Example 5 Weight = 27g/m CaC0,=18.5% Porosity = 50 seconds Processing: Wrapping it around a cigarette (wet a piece of paper on the thorn with water and let it dry.

Example 6 Weight = 27g/m' CaC0,=18.5% Porosity = 50 seconds Processing: Soak a piece of paper in 95% ethyl alcohol and dry before rolling it into a cigarette. .

In both of these examples, the performance was the same as in the implementation except that sidestream smoke was substantially reduced. Same as Example 1.

Fire resistance is further improved by depositing linear burn rate reducing materials in or on the paper. If this is the case, sidestream smoke t will also be reduced.

Deposition of linear burn rate reducing material using the same method as in Example 5.

By dissolving or suspending this substance in water and dipping the cigarette paper into it, It can be implemented very easily. Low porosity rolling soil using various materials The linear burning rate of paper can be reduced. An example of suitable processing will be described below. In each case The weight of one roll of cigarette paper is 271/m, and its Ca and Co content is 18.5%. Its porosity was 50 seconds. Before rolling this paper beg cigarette, linear burning rate decreaser Soak in a quality aqueous solution and dry.

7 Lactic acid 1% 1-50% 8 Citric acid 1% 1-10% 10 Magnesium acetate 5% 1-5% 11 Tartaric acid 1% 1-27% 12 Vinegar Acid 1% 1-20% In each of Examples 7-12, the effect of the linear burn rate reducing material on the fire test The substance used was charcoal [! The goal was to reduce The lower end of the concentration range is generally where carbonization is more pronounced. This is the point where a significant decrease occurred. Even if the concentration is increased to a level above the minimum effective level, Since almost no improvement occurs, high concentrations of combustion rate reducing substances without magnesium acetate are used. There is no reason to use it in degrees. In the case of magnesium acetate.

When the concentration is increased to 5%, sidestream smoke decreases even more noticeably.

the concentration of these combustion rate reducing substances to a level significantly higher than the upper limit of said range; Increasing the sound level has an undesirable effect on the appearance and groove of the cigarette paper.

Linear burn rate reducing material that can be applied from an aqueous solution to low porosity cigarette paper There are many others. Such substances include, for example, trisodium phosphate, Disodium acid, ammonium phosphorus, phosphoric acid, sulfuric acid, sodium hydroxide, phosphoric acid Rust.

Boric acid, ammonium hydroxide, nickel acetate, sodium silicate, ammonium sulfate ammonium sulfamate, and ammonium dichromate). this These substances should be applied at low concentrations, ie on the order of 1%; At high temperatures, the dark color of the ash from rolled cigarettes tends to occur (examples of Examples A17-12). The quality has almost no effect on the color of the ash, regardless of its concentration7).

Any burn rate reducing substances must be applied at very low concentrations through multiple treatment steps. Can be done. That is, a paper is soaked in a solution containing a solution of a burning rate reducing substance at a low concentration and then dried. Dry, then resoak in the same or another combustion rate reducing substance solution and dry again. .

Skimmed milk also acts as a linear burn rate reducer to reduce the charcoal content of materials used in fire resistance tests. It is effective for Skim milk can be conveniently applied as a suspension of skim milk in water. Wear. A typical analysis of skimmed milk (Carnation brand) is shown below: Water 6. 16% Protein 56.16% Lipid 0.77% Charcoal water 1himono 51.98% Ash content 7.95 Examples of the treatment of low porosity cigarette paper with skim milk are as follows: Example 15 Brainer porosity 50 seconds 1 weight 27g/rn” and Ca CO5 content 18.54 Add about 1 weight of skim milk to water on one side of Y cigarette paper. Treated with added suspension and dry. This treatment leaves a glossy finish on the treated side of the paper. This fire test In contrast, cigarettes made with treated paper are comparable to the same cigarettes made with untreated paper. In comparison, the test material produced significantly less charcoal and no smoldering at all. won.

The concentration of skimmed milk can range from about 1% to about 20%, but high concentrations within this range are not necessary. It's not even necessary. A shiny appearance on the outside of the cigarette wrapper is undesirable. In cases where non-fat milk suspension can.

Alternatively, both sides of the paper can be processed. Dilute with water instead of skimmed milk You can get the same effect using skim milk.

Various insoluble burning rate reducing substances other than milk can be applied as a hot suspension. Wear. An example of such a material is alumina gel.

Potato starch and aluminum stearate. One reference for these substances A typical aqueous suspension contains about 1 weight percent of such material. These materials have low porosity 7IY improvement in resistance to carbonization and ignition when applied to cigarette paper , and the side-stream explosion noise is reduced.

Cigarettes with low porosity paper do not tend to reduce tar content; Ventilation holes in the usual way around the filter? It is fixed by providing ventilation The holes do not affect the fire resistance of the cigarette or sidestream smoke generation.

The low-porosity wrapper has a fairly small effect on the smoke wicking properties of the cigarette, and it is sufficient to get into the mouth. It makes it only slightly more difficult to inhale large amounts of smoke than with regular cigarettes. do not have. The smoking properties of all cigarettes according to the invention are such that these cigarettes have a low , whether it's very low tar or high tar cigarettes.

It is acceptable and comparable to the smoking properties of conventional cigarettes. Revised The smoking of a good cigarette is different from that of a regular smoker of certain unimproved cigarettes. It is never so difficult as to be extremely unpleasant.

The same linear burn rate reducer used in the low porosity cigarette papers of Examples 7-12 was When applied to the highly porous paper used for regular cigarettes, it has excellent fire resistance and sidestream smoke reduction. Ras.

In the following examples of cigarettes using treated high porosity paper, the wrapper Y was not removed. By applying a treatment agent directly to the factory cigarette wrapper or cigarettes. , certain tobaccos of the test cigarettes were treated. The other cigarettes tested were wrapper Take out a cigarette from the rapper? By processing and first refilling the tobacco. Manufactured by Implementations using the latter method t1 shall be referred to by numbers followed by letters. (e.g. 17A). The latter method, as practiced in the manufacturing industry, It is obtained by first processing the tobacco paper and then forming it into t-rolled cigarettes. It mimics the results. Generally, for the latter method, the required amount of burning rate reducer is a small amount.

In the following examples, unless otherwise indicated, the tobacco charge will remain enclosed at the paper store. I understood.

In each of the following examples, one roll of cigarette paper had a Blaine porosity of 20 seconds, a weight of 24 g/ rrt and CaC0, content of 25%. Soak the paper in the listed treatment solution and dry. I let it happen.

In Examples 14 to 57, although a relatively low concentration of combustion rate reducing substances reduced sidestream smoke, Effective. If a higher concentration of burning rate reducing substance 2 is used, one roll of tobacco will be used. Ko will be able to pass the fire resistance test. The following table shows that the paper has a porosity of 20 seconds and 1 weight. Assuming a quantity of 24 g/rrl and a Ca, Co content of 25%, the treatment was carried out in a single immersion.

Depending on the presence of additives, and other possible factors, the degree of Ru.

Treating high porosity cigarette paper with milk as in implementation v315 By reducing sidestream smoke, fire resistance can be improved. Single-sided or double-sided paper sound It is applied to cigarette paper by treatment in a suspension of pores in water. next In the example, Breina porosity 20 seconds 1 weight 24jj/rrl and Ca Co, content Single stage degreasing of Carnation brand cigarette paper with 25% It was treated by applying the milk suspension to one side.

If there is a letter attached to the example number, is it one paper? Separated from tobacco and processed It means begging.

41 52.45 ... Unsatisfactory appearance Also in this case, low concentration combustion Velocity-reducing substances result in significant sidestream smoke reduction and fail standard tests at relatively high concentrations. This results in fire resistance that can be used for a long time. In the case of paper treated with cigarettes still wrapped, The minimum concentration of milk required to pass the fire test is 20 seconds for paper porosity and 20 seconds for weight. 249/rr1. and approximately 90%, assuming a CaCO3 content of 25%. Ru. For paper treated separately from tobacco, the minimum concentration is flZO%.

The minimum amount of these depends on porosity, amount of light agent, content per cigarette, type of tobacco, additives, etc. It is thought that it changes depending on the

The use of skimmed milk as a burn rate reducing agent is 1, e.g. citric acid.

Many advantages over the use of other burn rate reducers such as magnesium citrate etc. Show points. Treated cigarettes have a good appearance, are smooth, and are free from flexing. Easy to take out. It is also moisture resistant and has a long shelf life, making this paper suitable for other treatments. It is more flexible than rolling paper. In addition, the paper is wetted with skim milk suspension during processing. and maintain its strength.

When cigarette paper is treated with burn rate reducing substances, combustion A velocity reducing substance was applied to one side of the cigarette paper and the cigarette paper was treated. It is desirable to wrap it around the cigarette so that the side faces the cigarette. Burning rate reducing substances The concentration is so high as to produce a macroscopic deposit on a roll of paper as a suspension or solution. These steps are particularly desirable when These stages The tendency of burn rate reducing substances to affect the color of cigarette ash when oriented toward This is also desirable because there are fewer directions. Therefore, when processing one roll of paper, the first digit Relatively high concentrations of combustion wave reducers can also be used when directing toward the flame. Ru. This treatment method provides effective sidestream smoke reduction and effective fire protection. It has no substantial effect on the appearance of the smoke and its ashes.

The benefit of the present invention is to treat the entire surface area of the cigarette paper. It's not necessarily necessary. At least one roll of paper in the case of high porosity cigarette paper The porosity of the untreated area is reduced during each puff by applying the burn rate reducing material to only a portion of the surface area of the It is indeed desirable to help control the amount of tar and nicotine released into Yes.

When only a portion of the surface area of the paper is treated, the porosity of the paper is 1. Performance is influenced to some extent by the amount of combustion promoter used and the composition of the tobacco. roll Whether there are holes in the paper surrounding the Kitafu 5 filter or the porosity of this paper The performance of filter cigarettes is also affected by Similarly.

The performance of non-filtered cigarettes is only affected by the porosity of the paper. rather than the presence of a hole near the end of the cigarette closest to the smoker's mouth. is also affected. in general.

Cigarettes can be classified as “high tar” or “low tar” cigarettes depending on the factors listed above. It is classified as a cigarette. Low tar cigarettes are the standard type used in the tobacco industry. 15mg or less of tar sound is produced under stress. High tar cigarettes contain more than 15mg Up to 28 mg or more produces a tar sound. The effect of partial processing according to the present invention is It has been found that there is a correlation with the tar content classification of cigarettes.

The following is an example of a series of cigarettes treated with a substance that reduces the burn rate by reducing a portion of the surface area of the cigarette paper. vinegar. The paper was processed while still wrapped in a cigarette.

Example 42 Weight: Approximately 24,! 9/m CaC0,:+FI25% Kongyou; 20 seconds Tar: low content Processing: 90% of the surface area of the paper is immersed in a citric acid solution with a vertical gap of 2.5 mm. It is striped.

As a result, the burning rate of the two-set type was 6.16 mrtr/min for the corresponding untreated cigarette. In comparison, Fl is 1.79 mm/min. This cigarette is fireproof) Y pass showed a significant reduction in sidestream smoke. Fire-resistance test for partially treated cigarette paper The approximate minimum concentration when obtained with phosphoric acid is 25%.

Example 45 This example is the same as Example 42 except that the citric acid concentration is 55%. Ru. The linear burn rate is approximately 1.5 im/min.

This cigarette passed the fire test and exhibited low side-stream smoke.

The 55% concentration of citric acid is close to the upper limit for maintaining an acceptable cigarette appearance. It is.

Implementation 13’1J44 In this example, only 50 parts of the surface area of the wrapper is divided into five vertical lines of 4.5 rnri width. Basically, it is the same as Example 42 except that it was treated with citric acid. This volume Cigarettes did not pass the fire resistance test, and the reduction in side-stream smoke was not significant.

Example 45 Weight: 24g/m'.

CaC0,: fl 25% Porosity: 50 seconds Tar: High content Processing: 90% of the surface area of the paper (1<5.6%) Soaked in citric acid solution and dried Ru. The coating pattern is 22.5 mu vertical stripes including an untreated area of 2.5 rntx width. It has a convergence shape.

Results: The linear burning rate is approximately 2.5 art1 min. This cigarette is fireproof It passed the test and showed a substantial reduction in sidestream smoke.

In Example 4 In this example, the citric acid concentration is 55%? Same as Example 45 except . The linear burning rate is approximately 2.18 ax1 minute.

This cigarette passed fire tests and showed a substantial reduction in sidestream smoke. Section 55 is the upper limit of citric acid concentration to maintain acceptable cigarette appearance.

Example 47 This example only has 54% of the wrapper area? With citric acid, 4, 5 IOA width, etc. It is the same as Example 45 except that it is processed into vertical stripes at intervals. This rolled taba It passed fire resistance tests but showed no appreciable reduction in sidestream smoke.

Example 48 This example is similar to Example 45, except that the citric acid concentration is only 909%. is the same as Although this cigarette showed a substantial reduction in sidestream smoke, it did not pass.

Example 49 In this example, the citric acid concentration was 909%, and the treatment area was 6.5 mm apart. It is the same as the implementation group 145, except that the vertical stripes of the 18°7 dragon width are 75. Ru. This cigarette failed a fire test and had no appreciable reduction in sidestream smoke. Few? Didn't show it.

According to Examples 42 to 49, citric acid was used at a concentration of one component.

A portion of the cigarette wrapper, provided the ratio of treated area to total area of the wrapper is sufficient. Fire resistance and side-stream smoke reduction can only be achieved through treatment. high concentration Burn rate reducers are effective when applied to a relatively small portion of the total wrapper area; , low concentrations of burn rate reducers are effective when treating large areas of the total wrapper area. Concentration and area ratio are interrelated in that. Partial area processing is the processed area The pores of the paper are reduced, the pores of the untreated area are not affected, so air can pass through the paper. It passes into the smoke stream within the cigarette and is released to the smoker with each puff of a cigarette. It suppresses the amount of tar 2 nicotine and carbon oxide in smoke.

Low-turn cigarettes burn more quickly than high-tar cigarettes. A degree reducing material is generally required to provide fire resistance.

The same general observation that can be deduced from Examples 42-49 is that the high porosity cigarette paper Other substances used in the treatment of magnesium citrate, magnesium acetate , tartaric acid, acetic acid, lactic acid and sugar.

High tar cigarettes cause sidestream smoke reduction noise compared to low tar cigarettes. It has been discovered that a higher amount of burn rate reducer is required than for low porosity paper High-tar cigarettes made from paper are somewhat smaller than low-tar cigarettes made from low-porosity paper. Small processing area? It was also found that this is necessary to reduce sidestream smoke. But 1 roll Because the high tar properties of tobacco do not promote tobacco combustion, i.e. If it arises from the combustion characteristics of 1 cigarette tr high tar or low tar roll Classifying tobacco as smokeless tobacco has little impact on the effect of treatment area in determining sidestream smoke reduction. It will have no taste.

Treatment with milk as a combustion/death rate reducing agent, does high concentration milk have good fire resistance? arise but differ in that they tend to generate more sidestream smoke than intermediate concentrations. Next table The example below illustrates this result with high tar cigarettes. In the example, Porosity: 20 seconds 1 weight: 24.9/m, and Ca, Co, and T: 25%'& A suspension of Carnation brand skimmed milk gives this paper 6 ．． This hanging is done in equally spaced 4.5 regular width vertical stripes separated by 8n wide untreated areas. It was treated by applying a suspension.

In runs 50-61, the paper was processed while being wrapped around a cigarette.

52 11 90 Good + 55 15 50 Good + 54 15 75 Good + 55 15 90 Good Officer 56 14.9 50 good 10' 57 14.9 75 Good + 58 14.9 90 Good+ 59 16.6 50 Borderline +60 16.6 75 Borderline In +61 16.6 90 Borderline At concentrations above +16, the borderline Smoke emission has increased to an undesirable level. The maximum practical concentration of skim milk is approximately 1 It is 4.9%.

If the concentration is higher than this, the cigarette paper will darken to near the charcoal of the cigarette. This is because this dark color ratio is considered to be undesirable.

Among the examples described above, Example 560 cigarettes are preferred.

Since the treatment area is 50%, what is the amount of tar and nicotine in each puff of mainstream smoke? Mitsuru Air enters the cigarette through the holes in the paper in a controlled amount in minutes. .

The following examples are Examples 50 to 6, except that the cigarettes are low tar cigarettes. It is equivalent to 1. In this case as well, one piece of paper was processed while still being wrapped in a cigarette.

65 11 75 Insufficient + 64 11 90 Good + 65 15 50 Insufficient Master 68 14.9 50 Good 75 16.6 90 Good 10 These examples show that lower tar cigarettes require somewhat higher burn rates to reduce sidestream smoke. the need for a degree reducer or a larger treatment area and at least a low percent Regarding the treatment area of the It shows.

In this case, discoloration of the paper occurs at a density of about 16.6% or higher, so this density is not suitable for practical use. This is the highest concentration. In Examples 66 and 68, the treated area controlled tar and nicotine. The volume of these examples is such that a sufficient amount of nitrogen is introduced through the pores of the paper to control Particularly preferred is smoked tobacco.

For cigarettes with wrappers treated with burn rate reducing agents, only a portion of the total area When the cigarette is formed, the line extending in the length direction of the cigarette is It is possible to apply the combustion rate reducing agent in parallel, equally spaced lines with a width of 4I+llll1. preferable.

The circumferences of the cigarettes of Examples 42 to 75 were 25 discs. With a circumference smaller than this In cigarettes (so-called "thin" cigarettes), somewhat lower concentrations of burn rate reducers and satisfactory results are obtained with somewhat lower proportions of treated area.

For "thin" cigarettes, even if the burn rate reducing agent'aK was halved, the treatment It has the same fire resistance properties as a 25-roll cigarette.

Sidestream smoke reduction and ash color properties are obtained. For example, a circumference of 20mm and a 5% square Cigarettes with a porous wrapper treated with a magnesium chloride solution contain 5.9% Porous zipper treated with magnesium citrate solution - regular 25mm roll It exhibits the same performance as cigarettes. Similarly, treated with 3.8% nonfat dry milk suspension 20m cigarettes are made with regular 25 strips treated with 8.2 skimmed dry milk suspension. Shows the same performance as a rolled cigarette. 20mm rolled taba treated with 10% citric acid solution This shows the same performance as a 25" cigarette treated with a 22% citric acid solution.

Cigarettes of Examples 42 to 75 that exhibited sufficient sidestream reduction 7 and passed the fire resistance test; Also, other cigarettes according to the present invention that have passed the fire resistance test also produce light-colored ash. Therefore, there is no need to extinguish the rolled cigarette. These cigarettes require a certain number of puffs. ℃, less tobacco consumption than untreated cigarettes, satisfactory smoke absorption7 and is fully comparable to the amount of smoke produced by a conventional cigarette with an untreated wrapper. amount of smoke produced during each puff.

Certain advantages arise from processing cigarette paper in multiple successive stages.

Particularly effective sidestream smoke using low concentration burn rate reducers as solutions or suspensions reduction and fire resistance are achieved. Combining cigarette paper with a burn rate reducer in a single step It is possible to control the porosity by covering one part and the paper at another stage. By applying a very low concentration of burn rate retardant to the entire surface area of the Smoke reduction and fire resistance are guaranteed.

It is desirable, but not necessarily necessary, to place the final burn on the side of the paper facing the cigarette. Partial application steps are carried out by applying the rate retarder. By this This is because a rolled cigarette with a good appearance can be obtained. An example of a multi-step process is described below: Example 74 Grayna pore size 20 seconds 1M view 24g/ze and CaCO, content 25% low Tar cigarette paper and about 15% skimmed dry milk suspension tL on one side of the paper box. On 54% of It was treated by applying it as a coat. After drying, remove about 1% from the other side of the paper. Treated with fat dry milk suspension. This result is very similar to the result obtained in Example 59. was similar to The partially treated side was turned towards the cigarette end.

Example 75 Breina porosity 20 seconds 1 weight 24 g / rrj and CaCO3 content 25 A low tar cigarette paper containing 6.8 pieces of cigarette paper with 4.5 By applying a 15% non-fat dry milk suspension in equally spaced vertical stripes of the punishment width. Treatment (7. After drying.

The same side of the paper was coated with a 2.8% nonfat dry milk suspension over its entire area. Processed. One cigarette with the treated side of the paper facing out? Formed. Sidestream smoke reduction Although satisfactory, the cigarette failed the fire resistance test.

Example 76 The same treatment as in Example 75 was carried out except that the suspension concentration in the second stage was 4.8%. Ta. Sidestream smoke reduction was satisfactory and the single cigarette passed the fire resistance test.

Example 77 Except that the concentration of the first stage is 11.1% and the concentration of the second stage is 6.99%. The same treatment as in Examples 75 and 76 was performed.

Sidestream smoke reduction was uniformly better than Examples 75 and 76, and carbonization of the test material The fire resistance was better than Example 76 in that it was significantly less.

The following example concerns multiple treatment of cigarette paper with magnesium acetate solution. It is.

Example 78 Breina porosity 20 seconds 1 weight 24 g/m and CaCO content 25% Rolling paper for low tar cigarettes was rolled at 6.8-degree intervals over a wrapper loss of 0.54%. By applying 20% magnesium acetate solution as vertical stripes with a width of 4.5n, Processed. After drying, apply 9% magnesium acetate solution over the entire area on the same side of the paper. The liquid was applied. A cigarette roll was formed with the treated side of the paper facing out. This roll Although the cigarette failed the fire resistance test.

A satisfactory reduction in sidestream smoke was achieved.

Example 79 Except that the concentration at the partial application stage is 20% and the concentration at the complete application stage is 15%. , the same treatment 7 as in Example 7 was carried out. This cigarette is a satisfying way to reduce sidestream smoke. and passed the fire resistance test.

The difference between Examples 78 and 79 is that the second step of Example 78 was a 9% acetic acid magnesium acetate solution. The reason is that it was used for horses, and the cigarette of Example 78 failed the fire resistance test. . In Example 79, the concentration in the second stage was increased to 15%, and the cigarettes were subjected to sidestream tests and resistance tests. Passed both fire tests.

The inner part of the 5-roll cigarette wrapper was treated with magnesium acetate, and the outer part was treated with magnesium acetate. When the whole child is treated, good results are obtained as shown in the first example.

3”9 riyu Breina porosity 20 seconds 1 weight 24 g/m" and CaCO content 25% , low tar cigarette paper t, one side of this paper pfQ 5.8 mrx spacing Treated by applying 26% magnesium acetate solution in vertical stripes with a width of 4.5n. I understand) ゛ko. After drying, apply a 99% solution to the opposite side of the paper over its entire area. It was treated by smearing it. Turn the partially treated side towards the tobacco.

A cigarette was formed. This cigarette exhibits satisfactory sidestream smoke reduction and is fire resistant. I passed the strike.

Sugar can be used as a burn rate reducing agent, as the examples in the following table demonstrate.

In these examples, the porosity of one paper is 20 seconds.

The Ca and CO contents were 25% and the paper weight was 249/m. total area of paper was soaked in the specified sugar solution at the indicated concentration. The paper is then dried and tested for fire resistance. Sidestream smoke test) 7 lol. In the examples specified by numbers, In the example designated by a number followed by a single letter, the paper is processed as is from tobacco. Separated and processed.

81 Dextrose 50 + - 82 dextrose 50 + 10 85 Sucrose 50 10- 84 Sucrose 50 + 10 85 Maltose 20 10- 86 Maltose 25 + 10 87 Maltose 55 + + 81A Dextrose 20 10 - 81B Dextrose 50 + + 85A Sucrose 20-25 10-85A Maltose 16.6-19 ．． 5 + 85B Maltose 20.65 + 10 Odors for each of these examples As a result, the cigarettes produced a white ash with an acceptable appearance.

The practical upper limit of sugar concentration is about 60%, and highly concentrated sugar solutions are difficult to dry and sticky. It is gender.

In the case of sucrose, at a concentration of 25% or higher in Example 85A, one paper is a combustible charcoal It was almost discolored. Therefore, in the case of rolled cigarettes where one paper is processed separately from the tobacco, , it is impossible to obtain both sidestream smoke reduction and fire resistance with an aqueous solution containing only sucrose. It was Noh. Similar discoloration has been observed with high concentrations of maltose. . The discoloration problem is caused by sucrose and other burn rate retarders (e.g. 15.7% sucrose). or by using a mixture of sucrose and 5.88% citric acid). 2 treatment steps, applying with drying after each step (e.g. 7% screen at each step) This can be avoided by smearing the loin). sucrose is alcohol It can be applied as a liquid solution, in which case a relatively low concentration of 11. Good results when used as 2% sucrose’Y94.4% ethyl alcohol solution You can beg for it.

The sugar solution can be applied in two stages, one of which is partial application.

An example is described below: Example 88 Porosity 20 seconds, CaC0, content 25 and weight 24,! 9. /　7r+'Y Yes low tar cigarette paper with 6I1 spacing of 2n over 75% of its area. m width stripes were treated with a 50% dextrose solution, dried and then The entire area was treated with 55% sucrose solution and dried again. processed Paper? Cigarettes used as wrappers showed good sidestream smoke reduction and were tested in fire resistance tests. Example 88 is the same as Example 88 except that maltose was used instead of dextrose. is the same as The results were the same as those of Example 88.

Example 90 Example 88 and I asked for the same treatment as 89. The results were the same as those of Examples 88 and 89.

The lower concentration limit of each treatment step in a multiple treatment with sugars depends on the concentrations of the other treatment steps.

However, in general, the lower concentration limit for the partial treatment stage is about 50%, and the lower concentration limit for the complete treatment stage is approximately 50%. The lower limit of degree is about 20%.

Low porosity paper using an auxiliary layer of traditional cigarette paper? Used cigarettes or high The performance of cigarettes made using porous paper can be improved. Low porosity paper roll The use of the cigarette paper supplementary layer in tobacco is illustrated in the following example: Example 9 1 , the second cigarette had an inner wrapper exhibiting the following characteristics Z: Weight: 24 g/ m’ CaC0, content: 20% Porosity: 50 seconds The outer wrapper is made from highly porous cigarette paper that adheres to the inner side and exhibits first-order properties. Become: Weight: approx. 24g/ze CaCO3: Approximately 25% Porosity: 20 seconds This cigarette exhibits substantially improved fire resistance and only has a low porosity wrapper. It produced significantly less sidestream smoke than the cigarette of Example 3.

The use of refill wrappers can be achieved by using specially treated wrappers as described in the following examples. It also improves the performance of rolled cigarettes.

Example 92 In this example, the inner wrapper has a porosity of 2Os and a weight of 24g/m'.

CaC0, content 25%. 4.5% Magnesium Citrate (Mgs(Ce) Consisting of cigarette paper soaked in a solution, the outer wrapper is Magnesium citrate? It was made of the same paper without any with outer wrapper The inner wrappers were in close contact with each other. This cigarette has good fire resistance and good side effects. Reduced smoke! Indicated. Comparing this example with Example 22, the fire resistance and sidestream smoke reduction The outer wrapper has the effect of reducing the concentration of substances that reduces the burning rate necessary to achieve It is recognized that the company has

Volumes in which auxiliary wrapper intervention uses combustion rate reducing substances other than magnesium citrate 1 has been discovered to improve the performance of tobacco.

When the treated wrapper is placed on the outside and the non-treated wrapper is placed on the inside, the cigarette It has also been discovered that the properties of are not specifically affected. Only a portion of the total area is mentioned above. Similarly, using auxiliary lacquer on cigarettes with lacquer treated with It has also been found that good results can be obtained.

Citric acid, magnesium citrate, magnesium acetate, tartaric acid, acetic acid, lactic acid, sugar , or treated with a burning rate reducing agent of the group taken from skim milk or skim milk suspension. In the case of rolled cigarettes.

Reducing the concentration of these secondary combustion rate reducing substances does not limit the presence of other combustion rate reducing agents. The performance of Runauba cigarettes is not impaired.

Available burn rate reducers that can be added include ammonium phosphate, Ammonium phosphate, ammonium sulfamate, boric acid and sulfamine It's a song. For example, add 22% citric acid to a regular porous 25mm cigarette. This cigarette wrapper contains 79% citric acid and 5% sulfamic acid. Fire resistant by treatment with a solution consisting of Monium.

The same results are obtained regarding sidestream smoke reduction and ash coloration.

1st group of combustion rate reducing substances (citric acid, citric acid magnesium skim milk) 21 "Winston Light" cigarettes for use in combination with 5 as shown in the following examples. An aqueous solution consisting of 12% citric acid and 8% sucrose was applied over the entire area of the wrapper. The liquid was applied. The burning speed of the wrapper was slowed down due to this treatment. So, what is the length of the tobacco rod? : 10mm reduction (from 55mm to 45 dragons), It is now possible to extend the filter length by 10 mm (from 22 mm to 52 mm). Ta. The original cigarette produced 8 puffs, but the new cigarette produced 10 puffs. A sound occurred. This cigarette passed the fire resistance test. From this new cigarette The side-stream smoke was clearly visible. The coloring of the ash, the amount of smoke absorption, and the smoke absorption properties are It was the same as a rolled cigarette, and the taste was somewhat milder. This new makitaba The free burning time of F:J is 5 minutes, and the linear burning rate is about 5 minutes/minute. was in contrast to the original cigarette's linear burn rate of 5.5 mm/min. child This is a decrease of about 45 factors. A 40% reduction is the preferred minimum reduction.

Example 94 Another Winston Wright cigarette wrapper Kaoru 5% over its entire area Treated with magnesium citrate and 12.2% citric acid. This rolled cigarette resulted in less sidestream smoke and good fire resistance. The tobacco rod is a regular wince It was 15 mm shorter than the Ton Light cigarette, and the filter was 15 mm longer.

This cigarette produced 14 puffs. The taste was satisfying. gray coloring The amount of smoke absorbed and the smoke absorption properties were the same as the original cigarette. Free burning time is approximately 5 minutes and the linear burn rate was 1.7 dishes/min.

Implementation]95 o y, -r y 7 (A/King with tar (Rothman Filt) er King) Remove the tobacco from the rolled cigarette and sprinkle water on the entire surface of the nitrogen wrapper. Medium 4.2% Carnation Brand Nonfat Dry Milk and 2.54% Powder in Water A mixture consisting of sucrose was applied and the bass was allowed to dry and refilled with tobacco.

The tobacco rod was 58 cm long, and the filter and mouthpiece paper occupied 25 mm. . The dry weight increase of the paper was 5 mg. Rolled cigarettes are made of regular paper color and appropriate It showed smoke absorption properties. The paper had a slight gloss on its surface, resulting in untreated paper. This roll Tobacco has excellent fire resistance and leaves only a slight stain on cotton surfaces in fire resistance tests. I just left it behind.

This allowed for 14 puffs compared to 11 puffs from an untreated cigarette.

Static free burn time was 6-8 minutes. Sidestream smoke has been substantially reduced. The tar is It was roughly the same as untreated cigarettes, but the taste was milder and the irritation was significantly less. There weren't many. Also accepts mixtures of nonfat dry milk and other sugars such as maltose It is possible. The amount of tar produced depends on the use of perforated or porous filter paper. Depending on the use, or shorten the tobacco rod by 5-10mm and adjust the filter accordingly. It can be easily reduced by lengthening it. Tobacco rondo begging is shortened, The effective number of puffs is reduced to a normal number (typically 11).

As mentioned in the last 5 embodiments, the length of the cigarette can be shortened and the filter can be lengthened. By processing wrappers or by using special wrappers, This applies to all cigarettes that have a reduced burning speed. resulting in a slow burning rate In some cases, it may be possible to increase the amount of tar, but it is also possible to increase the length of the filter. The increase in tar can be prevented by The tar content of the emitted smoke is low (as discussed above with respect to Examples 42-9o). Further significant reductions can be made by treating only a portion of the wrapper loss. become capable.
