Abstract
The tobacco sheet contains 15-60% by mass of tobacco material, 20-70% by mass of cellulose fiber, has a thickness of 55-85 μm, and a basis weight of 25-42 g/m2The tensile strength is 12N/15mm or more.
Description
Technical Field
The present invention relates to tobacco sheets comprising tobacco material.
Background
A tobacco paper containing a tobacco material has been disclosed (international publication No. 96/32854). The tobacco paper is intended to surround the tobacco filler material in a cylindrical shape. The tobacco paper contains at least twice the basis weight of the tobacco material of the base paper. Tobacco paper is also known as tobacco sheet.
Disclosure of Invention
Technical problem to be solved by the invention
Since such a tobacco sheet contains a tobacco material, the tensile strength of the tobacco sheet is lower than that of a conventional cigarette wrapper. Therefore, when the tobacco paper is used in a conventional tobacco winding machine, the tobacco paper is easily broken during the production.
In addition, the adhesion of the tobacco paper by the adhesive is insufficient. Therefore, in the tobacco rod wound with the tobacco paper, a burst roll in which the tobacco rod is broken, which is a poor adhesion, is liable to occur during the manufacturing. When the adhesive is added to improve the adhesiveness, appearance defects due to the overflow of the adhesive occur. In addition, when the temperature of the heater in the cigarette winding machine is increased to improve the adhesiveness, the tobacco paper is easily burned to cause poor appearance. Further, measures are taken to improve the adhesiveness by ensuring a sufficiently long curing time of the adhesive, but the rotational speed of the cigarette winder is thereby reduced, and the manufacturing efficiency is lowered.
The object of the present invention is to provide a tobacco sheet that can be used directly in existing cigarette wrapping machines and by using the cigarette wrapping machine, can produce a smoking article at high speed.
Means for solving the problems
A tobacco sheet according to one embodiment of the present invention contains 15 to 60 mass% of a tobacco material and 20 to 70 mass% of a cellulose fiber, and has a thickness of 55 to 85 μm and a basis weight of 25 to 42g/m2The tensile strength is 12N/15mm or more.
Effects of the invention
According to the present invention, it is possible to provide a tobacco sheet that can be directly used in an existing cigarette wrapping machine and by using the cigarette wrapping machine, a smoking article can be manufactured at high speed.

Detailed Description
Hereinafter, an embodiment of a cigarillo as a smoking article using a tobacco sheet as a wrapping paper will be described with reference to fig. 1 to 4. The following description is for the purpose of illustrating the invention and is not intended to limit the invention. In addition, the drawings schematically show the respective constituent elements of the invention. Therefore, the dimensions on the drawings may not necessarily correspond to the dimensions of an actual product.
The cigarillo 11 is a kind of cigarette, and has approximately the same appearance and configuration as a normal cigarette. Cigarillos 11 differ from cigarettes only in that they use tobacco sheets instead of a paper wrapper for wrapping the tobacco filler material. The cigarillo 11 includes a tobacco rod 12, a filter section 13 provided adjacent to the tobacco rod 12, and tipping paper 14 connecting the tobacco rod 12 and the filter section 13.
The filter portion 13 has a cylindrical shape. The filter unit 13 includes a filter main body 15 and a wrapping paper 16 covering the periphery of the filter main body 15. The overlapping portion between the end portions of the wrapping paper 16 is bonded with an adhesive such as a vinyl acetate emulsion.
The filter body 15 can be formed of various kinds of filler materials. In the present embodiment, the filter body 15 is made of, for example, a filler of cellulose-based semisynthetic fibers such as acetate, but the filler is not limited thereto. For example, as the filler, plant fibers such as cotton, hemp, abaca, palm, and orchid, animal fibers such as wool and cashmere, cellulose-based regenerated fibers such as rayon, cellulose-based semi-synthetic fibers such as diacetate and triacetate, synthetic fibers such as nylon, polyester, acrylic, polyethylene, and polypropylene, or a combination thereof can be used. The filter unit 13 may be a carbon filter containing carbon particles or a filter containing particulate matter other than carbon particles, in addition to the acetate filter described above. The filter unit 13 may be formed of two or more segments.
In addition, the filter body 15 can contain a plasticizer. The type of plasticizer used in the filter body 15 of the filter unit 13 is not limited. For example, triethyl citrate, acetyl tributyl citrate, dibutyl tartrate, ethyl ethylphthaloyl glycolate, methyl ethyl phthalate, triacetin, triethyl phosphate, triphenyl phosphate, tripropionin, or a combination thereof can be used. The plasticizer may not be used depending on the case.
The filter body 15 may contain a flavor such as menthol. The method of perfuming a perfume is not particularly limited, and for example, a string-like substance that absorbs a perfume is disposed in the filter main body 15, a perfume is contained in the filler of the filter portion 13, or a material obtained by immobilizing a perfume such as a capsule is disposed in the filter portion 13.
The type and material of the roll paper 16 are not limited. The wrapping paper 16 may be breathable, or may be non-breathable, as is used for typical smoking articles. The material of the wrapping paper 16 is generally paper made of plant fibers, and may be a sheet made of chemical fibers of a polymer material (for example, polypropylene, polyethylene, nylon, or the like), a sheet made of a molten material of a polymer material, or a sheet made by molding a metal foil such as an aluminum foil.
The filter body 15 may use an unwrapped filter as in figure 15 of international publication No. 2004/066761. The uncoated filter has a filter material and an outer skin layer formed by thermoforming the filter material into a cylindrical shape. Thus, no paper need be wound in the case of an unwrapped filter.
The material of the tipping paper 14 is not limited. The tipping paper 14 is generally made of paper (pulp) made of plant fibers, and may be made of chemical fibers made of a polymer material (for example, polypropylene, polyethylene, nylon, or the like), or may be made of a sheet formed by molding a melt of a polymer material, or may be made of a metal foil such as an aluminum foil.
The tobacco rod 12 has a tobacco filler material 17 and a paper wrapper 18 wrapped around the tobacco filler material 17. The roll paper 18 has a superposed portion formed by superposing end portions. In the overlapping portion, the ends of the roll paper 18 are bonded to each other with an adhesive agent such as a vinyl acetate resin emulsion.
Generally, the tobacco filler 17 is formed of cut tobacco (i.e., short tobacco filler) obtained by cutting tobacco leaves (i.e., dried tobacco leaves used for smoking articles) into predetermined lengths and widths. The tobacco filler material 17 may also comprise tobacco shreds which are formed into sheets and cut into elongate shapes, i.e. sheet-like shaped articles. The sheet-like formed article may be constituted by a tobacco sheet 21 described later. The sheet-like molded article may contain an aerosol-generating substrate or a perfume component. An aerosol-generating substrate or a flavor component may be added to the cut tobacco. Examples of aerosol-generating substrates include glycerin, Propylene Glycol (PG), triethyl citrate (TEC), triacetin, and 1, 3-butanediol. One kind of them may be used, or two or more kinds may be used in combination.
The wrapping paper 18 is made of a tobacco sheet 21, which is paper containing a tobacco material. The tobacco sheet 21 contains cellulose-based fibers in addition to the tobacco material. The tobacco sheet 21 is generally formed of a paper-making sheet formed by a general paper-making process, and may be formed by another method (for example, rolling, casting, or the like).
The cellulose-based fiber is generally pulp, and is, for example, one or more of wood pulp, non-wood pulp, and synthetic fiber pulp. The cellulosic fiber is preferably wood pulp. Notably, cellulose-based fibers do not contain tobacco-derived fibers. The tobacco sheet 21 may contain 20 to 70 mass% of cellulose fibers, preferably 25 to 65 mass% of cellulose fibers, and more preferably 30 to 60 mass% of cellulose fibers.
The tobacco sheet 21 may contain other additives such as fillers and combustion improvers. The tobacco sheet 21 preferably contains 10 to 40 mass% of other additives, more preferably 15 to 35 mass% of other additives, and most preferably 20 to 30 mass% of other additives. The other additives may be any one of calcium carbonate, aluminum hydroxide, alumina, titanium dioxide, kaolin, talc and silica, or a mixture of any two of them.
The tobacco sheet 21 has a basis weight of 25 to 42g/m2Preferably 28 to 40g/m2More preferably 30 to 39g/m2Most preferably 32 to 38g/m2。
The thickness of the tobacco sheet 21 is 55 to 85 μm, preferably 60 to 80 μm, more preferably 65 to 78 μm, and most preferably 69 to 76 μm.
The tobacco sheet 21 is preferably subjected to a calendering process. The calendering process is to smooth an object (i.e., a tobacco sheet) between smooth rollers, to give gloss to the object, to compress the object, and to reduce or average the thickness of the object. In this case, one of the rollers is an iron roller, and the other roller is an elastic roller formed by winding an elastic material such as paper, cotton, or rubber around the iron roller.
The tensile strength of the tobacco sheet 21 may be 12N/15mm or more, preferably 12 to 30N/15mm, more preferably 13 to 20N/15mm, and most preferably 13 to 15N/15 mm. The tensile strength was measured according to JISP 8113: 2006. The actual tensile strength was measured using a tensile tester (ストログラフ E-S) manufactured by Toyo Seiki Seisaku-Sho.
The stiffness of the tobacco sheet 21 may be 15cm3A value of 100 or less, preferably 10 to 15cm3A value of/100, more preferably 11 to 14cm3A/100, most preferably 12-13 cm3/100. The stiffness was determined according to JISP 8143: 2009. The actual tensile strength was measured using a stiffness tester manufactured by Toyo Seiki Seisaku-Sho. It is noted that if the rigidity can be reduced, the adhesion is in the peeling directionThe upward force (repulsive force) decreases. As a result, the drying time of the adhesive can be shortened, thereby increasing the winding speed of the tobacco rod 12. Specifically, the winding speed can be increased not only in the production of tobacco rods having a circumference of 23mm to 27mm (so-called normal size), but also in the production of tobacco rods having a circumference of 16 to 23mm (so-called slim cigarette size) (i.e., tobacco rods having a circumference of 18 to 23mm (so-called thin size) and tobacco rods having a circumference of 16 to 18mm (so-called ultra-thin size)).
The baker's smoothness of the tobacco sheet 21 may be 15sec or more, preferably 15 to 30sec, more preferably 17 to 27sec, and most preferably 19 to 24 sec. Determination of the Beck smoothness is carried out according to JIS P8119: 1998. The actual Beck smoothness was measured using a digital Beck (デジベック) smoothness tester manufactured by Toyo Seiki Seiko Seiki Seiko Seiki. Notably, the Beck smoothness means that the larger the number, the smoother the measurement object surface. If the Beck smoothness becomes larger, the coating state of the adhesive and the adhesive strength are improved, and as a result, the drying time of the adhesive is shortened, and the winding speed of the tobacco rod 12 is increased.
Next, a method for manufacturing the wrapping paper 18 (tobacco sheet 21) and a method for manufacturing a smoking article using the wrapping paper 18 according to the present embodiment will be described.
The wrapping paper 18 (tobacco sheet 21) of the present embodiment can be produced by a method in which a part of a generally known paper making process is slightly changed.
The paper making process for producing the wrapping paper 18 (tobacco sheet 21) of the present embodiment includes four steps of (1) pulping, (2) conditioning, (3) papermaking, and (4) processing and finishing, as in the known paper making process.
(1) In the pulping process, chemical and mechanical treatments are performed. In this step, cellulose-based fibers, i.e., pulp, are extracted from wood. The pulp is dewatered and bleached after the removal of the entrained dust.
(2) The conditioning step includes two steps of disintegration using a pulper and beating using a beater (refiner). The dissociated paper pulp is mixed with water uniformly. The pulp mixed with water is mixed with tobacco leaves cut into minute pieces in another step. The beater further cuts the pulp and tobacco flakes into short fibers, and simultaneously fluffs (fibrillates) the short fibers so that the fibers are easy to combine.
In the wrapping paper 18 (tobacco sheet 21) of the present embodiment, the degree of fibrillation can be made higher and the union between fibers can be made stronger by increasing the degree of beating in a known paper making process. The degree of beating can be increased, for example, by causing beating to be performed under conditions stricter than beating conditions performed in a known papermaking process (for example, by increasing the concentration of the raw material or by reducing the flow rate of the raw material). Higher degrees of fibrillation proceed and stronger associations between fibers can increase the strength of the tobacco sheet while reducing the grammage. A reduction in grammage of the tobacco sheet can be associated with a reduction in thickness and a reduction in stiffness.
(3) In the paper-making step, the material fed from the adjustment step is made into actual paper. In the net part, a mixed liquid of pulp, tobacco leaves and water is uniformly spread. In the pressing portion, water is squeezed out of the liquid mixture. In the drying section, the base paper of the tobacco sheet from which moisture has been removed is dried. In the calendering section, the surface of the tobacco sheet base paper is smoothed. The produced tobacco sheet base paper is wound into a roll shape at a reel portion.
(4) In the processing and finishing step, the surface of the tobacco sheet base paper is smoothed by a calender. The calendering apparatus includes a first iron roll and a second elastic roll opposed to the first roll. The calendering device is capable of forming a calendered smooth tobacco sheet by nipping and pressing a base tobacco sheet between a first roll and a second roll. The second roller is a roller formed by winding an elastic material such as paper, cotton, or rubber around an iron roller to give elasticity to the surface thereof. The tobacco sheet 21 is finished by applying the calendering process by the calendering device and other processes and post-treatments such as coating, cutting, and rolling, if necessary.
The tobacco sheet 21 is mounted on a conventional general cigarette wrapping machine to form the tobacco rod 12. The tobacco rod 12 is connected to a filter unit 13 formed in another step via a tipping paper 14, whereby a smoking article (i.e., a cigarillo 11) is produced.
The tobacco sheet 21 and the smoking article (i.e., cigarillo 11) produced using the same are not limited to those described in the above embodiments and modifications, and the components may be modified and embodied in the implementation stage without departing from the scope of the main contents thereof. In addition, some of all the components described in the embodiments may be deleted.
The roll paper of examples 1 and 2, comparative examples 1 and 2, and reference example has various parameters as shown in tables 1 to 3 below.
[ Table 1]
[ Table 2]
[ Table 3]
[ example 1]
In the cigarillo 11 of example 1, the wrapping paper was constituted by the tobacco sheet 21 containing cellulose-based fibers and a tobacco material. The tobacco sheet 21 contains 50 mass% of tobacco material and 30 mass% of wood pulp. The tobacco sheet 21 contains 20 mass% of other additives such as fillers and combustion improvers. The grammage of the tobacco sheet 21 is 38g/m 2. The thickness of the tobacco sheet 21 was 76 μm. The tobacco sheet 21 of example 1 was subjected to calendering.
The tensile strength of the tobacco sheet 21 was 15N/15 mm. The stiffness of the tobacco sheet 21 was 12cm3/100. The bakery smoothness of the tobacco sheet 21 was 19 sec.
The tobacco sheet 21 thus constructed is used to produce the tobacco rod 12 and the cigarillo 11. A cigarette winder used for producing general cigarettes is used for winding the tobacco rod 12 and producing the cigarillo 11 including the tobacco rod 12. The speed of manufacture of the cigarillo 11 is 8000 cpm. The cpm refers to the number of small cigars 11 made per 1 minute. The speed of the tobacco sheet 21 through the heater of the cigarette winder was 456 m/min.
As the adhesive for bonding the end portions of the tobacco sheet 21, an adhesive made of a vinyl acetate resin emulsion is used. The amount of the binder was 125% by mass when the mass used for bonding between the ends (overlapped portion) of the "general cigarette wrapping paper" used in the reference example was 100%.
The amount of the binder is the amount ratio (%) of the binder calculated by the following formula in table 3. The amount ratio (%) of the binder { (mass of binder used when winding a cigarillo as an object)/(mass of binder used when winding the cigarette of reference example) } × 100
In the cigarette winder, the temperature of the heater used to dry the adhesive was 280 ℃. In this embodiment, there is no problem in winding suitability, and breakage, i.e., bursting of the roll, due to poor adhesion of the tobacco rod 12 during winding does not occur. In addition, the tobacco sheet 21 is not burnt by heating when drying the binder.
Sensory evaluation by the test persons was performed on the mouthfeel of the cigarillo 11 of example 1. As a result, the test person evaluated that "the little cigar (japanese tobacco industry co., ltd.) had a fibrous feeling but had a reduced unpleasant taste as compared with" golden bat "which is a commercial product. In general, the flavor and the smoke taste of the flavor added to tobacco tend to be increased and the bitterness tends to be reduced. Mouthfeel is in the category of established products. Therefore, the cigarillo 11 of example 1 had a substantially good taste.
[ example 2]
In the cigarillo 11 of example 2, the wrapping paper was constituted by the tobacco sheet 21 containing cellulose-based fibers and a tobacco material. The tobacco sheet 21 contains 20 mass% of tobacco material and 60 mass% of wood pulp. The tobacco sheet 21 contains 20 mass% of other additives such as fillers and combustion improvers. The grammage of the tobacco sheet 21 is 32g/m2. The thickness of the tobacco sheet 21 was 69 μm. The tobacco sheet 21 of example 2 was subjected to calendering.
The tensile strength of the tobacco sheet 21 was 13N/15 mm. The stiffness of the tobacco sheet 21 was 13cm3/100. The bakery smoothness of the tobacco sheet 21 is 24 sec.
The tobacco sheet 21 thus constituted is used to produce the tobacco rod 12 and the cigarillo 11. A general cigarette winder is used for winding the tobacco rod 12 and manufacturing the cigarillo 11 including the tobacco rod 12. The manufacturing rate was 6000 cpm. The speed of the tobacco sheet 21 through the heater of the cigarette wrapping machine was 342 m/min.
As the adhesive for bonding the end portions of the tobacco sheet 21, an adhesive made of a vinyl acetate resin emulsion is used. The amount of the binder was 125% by mass when the mass used for bonding between the ends (overlapped portion) of the "general cigarette wrapping paper" used in the reference example was 100%. In the cigarette winder, the temperature of the heater for drying the adhesive was 280 ℃. In the present embodiment, there is no problem in winding suitability, and there is no occurrence of breakage due to poor adhesion of the tobacco rod 12 during winding, that is, so-called bursting roll. In addition, the tobacco sheet 21 is not burnt by heating during drying of the binder.
Sensory evaluation by the test person was performed on the mouthfeel of the cigarillo 11 of example 2. The test persons evaluated that "sweet taste left in the mouth tends to be increased" as compared with a small cigar (Nippon tobacco industry Co., Ltd.) of "gold bat" which is a commercial product. The intensity, sucking response, bitterness were further reduced (i.e. compared to the cigarillo of example 1), with a reduced cigarillo-like sensation; mouthfeel falls within the allowed range ". Therefore, the taste of the cigarillos 11 of example 2 falls within the allowable range of established products.
Comparative example 1
In the cigarillo 11 of comparative example 1, the wrapping paper was constituted by the tobacco sheet 21 containing cellulose-based fibers and a tobacco material. The tobacco sheet 21 contains 70 mass% of tobacco material and 10 mass% of wood pulp. The tobacco sheet 21 further contains 20 mass% of other additives such as fillers and combustion improvers. The grammage of the tobacco sheet 21 is 46g/m2. The thickness of the tobacco sheet 21 was 106 μm. The tobacco sheet 21 of comparative example 1 was not subjected to the calendering treatment.
The tensile strength of the tobacco sheet 21 was 10N/15 mm. The stiffness of the tobacco sheet 21 was 18cm3/100. The bakery smoothness of the tobacco sheet 21 was 7 sec.
The tobacco sheet 21 thus constituted is used to produce the tobacco rod 12 and the cigarillo 11. A general cigarette winder is used for winding the tobacco rod 12 and manufacturing the cigarillo 11 including the tobacco rod 12. The manufacturing speed was 2000 cpm. The speed of the tobacco sheet 21 through the heater of the cigarette winder was 114 m/min.
As the adhesive for bonding the end portions of the tobacco sheet 21, an adhesive made of a vinyl acetate resin emulsion is used. The amount of the binder was 250% by mass when the mass used for bonding between the ends (overlapped portion) of the "general cigarette wrapping paper" used in the reference example was 100%. In the cigarette winder, the temperature of the heater used to dry the adhesive was 280 ℃. In this comparative example, breakage, so-called bursting roll, occurred during the winding due to poor adhesion of the tobacco rod 12. Therefore, the cigarillo 11 of comparative example 1 has a problem of winding applicability. In addition, no scorching of tobacco sheet 21 occurs due to heating during drying of the binder.
Comparative example 2
In the cigarillo 11 of comparative example 2, the wrapping paper was constituted by the tobacco sheet 21 containing the cellulose-based fiber and the tobacco material. The tobacco sheet 21 contains 50 mass% of tobacco material and 30 mass% of wood pulp. The tobacco sheet 21 further contains 20 mass% of other additives such as fillers and combustion improvers. The grammage of the tobacco sheet 21 is 46g/m2. The thickness of the tobacco sheet 21 was 99 μm. The tobacco sheet 21 of comparative example 2 was subjected to calendering treatment.
The tensile strength of the tobacco sheet 21 was 11N/15 mm. The stiffness of the tobacco sheet 21 was 18cm3/100. The bakery smoothness of the tobacco sheet 21 was 10 sec.
The tobacco sheet 21 thus constituted is used to produce the tobacco rod 12 and the cigarillo 11. A general cigarette winder is used for winding the tobacco rod 12 and manufacturing the cigarillo 11 including the tobacco rod 12. The manufacturing rate was 4000 cpm. The speed of the tobacco sheet 21 through the heater of the cigarette winder was 228 m/min.
As the adhesive for bonding the end portions of the tobacco sheet 21, an adhesive made of a vinyl acetate resin emulsion is used. The amount of the binder was 125% by mass when the mass used for bonding between the ends (overlapped portion) of the "general cigarette wrapping paper" used in the reference example was 100%. In the cigarette winder, the temperature of the heater used to dry the adhesive was 280 ℃. In this comparative example, breakage, so-called bursting roll, occurred during the winding due to poor adhesion of the tobacco rod 12. Therefore, the cigarillo 11 of comparative example 2 has a problem of winding applicability. In addition, no scorching of tobacco sheet 21 occurs due to heating during drying of the binder.
[ reference example ]
In the smoking article of the reference example, "general cigarette wrapping paper" containing cellulose fibers as a main component and containing no tobacco material was used. Therefore, the smoking article of the reference example is not a cigarillo but a cigarette. The cigarette wrapper contained 70 mass% of wood pulp. The cigarette wrapper further contains 30 mass% of other additives such as fillers and combustion improvers. The gram weight of the cigarette paper is 26g/m2. The cigarette wrapper had a thickness of 45 μm. The wrapping paper for cigarette of the reference example was not subjected to the calendering treatment.
The tensile strength of the "ordinary cigarette wrapping paper" was 14N/15 mm. The cigarette paper had a rigidity of 9cm3/100. The cigarette wrapper had a beck smoothness of 48 sec.
The tobacco rod 12 and the cigarette are produced using the "general cigarette wrapping paper". A general cigarette winding machine is used for winding the tobacco rod 12 and manufacturing a cigarette including the tobacco rod 12. The manufacturing rate was 9000 cpm. The speed of the cigarette wrapping paper passing through the heater of the cigarette winder was 513 m/min.
As the adhesive for bonding the end portions of the common cigarette wrapping paper, an adhesive made of a vinyl acetate resin emulsion is used. In a typical cigarette, the amount of the binder is 100% by mass because the mass used for bonding the end portions (overlapped portions) of the wrapping paper is 100%. In the cigarette winder, the temperature of the heater used to dry the adhesive was 200 ℃. Each condition of the present reference example is an actual condition used in general cigarette wrapping, and therefore there is no problem of the wrapping applicability. Therefore, the cigarette cannot be broken, i.e., burst, due to poor adhesion of the tobacco rod during winding. In addition, the tobacco sheet 21 is not burnt by heating when drying the binder.
[ evaluation of relationship between rigidity and thermal efficiency ]
First, the "drying heat" is defined as follows.
Drying heat ═ heater temperature (. degree. C.)/speed of web passing through heater (m/min)
Next, "thermal efficiency (%)" is defined as follows.
Thermal efficiency (%) × 100 [ { (the amount of drying heat of cigarette of reference example)/(the amount of drying heat of cigarillo of object) }/(the amount ratio of binder) ]
The "amount ratio of the binder" is defined as above.
Amount ratio (%) of binder { (mass of binder used in winding of target cigarillo)/(mass of binder used in winding of cigarette of reference example) } × 100
Here, fig. 3 shows the relationship between the rigidity and the thermal efficiency of examples 1 and 2, comparative examples 1 and 2, and a reference example. The results show that: the lower the stiffness, the higher the thermal efficiency. This is because the stiffness of the wrapping paper decreases, and the force (repulsive force) in the peeling direction at the time of bonding decreases, resulting in shortening the drying time of the adhesive and thus increasing the winding speed of the tobacco rod.
From this evaluation, the following conclusions can be drawn. That is, in comparative examples 1 and 2, as in the tobacco sheets of examples 1 and 2, if the rigidity can be reduced, the manufacturing efficiency of cigarillos can be improved.
[ evaluation on the relationship between Beck smoothness and thermal efficiency ]
Fig. 4 shows the relationship between the baker smoothness and the thermal efficiency of examples 1 and 2, comparative examples 1 and 2, and a reference example. The results show that: the higher the beck smoothness, the higher the thermal efficiency. This is because the coated state of the adhesive becomes smooth by the wrapping paper and the adhesive strength improves, resulting in shortening the drying time of the adhesive and thus increasing the winding speed of the tobacco rod 12.
From this evaluation, the following conclusions can be drawn. That is, in comparative examples 1 and 2, as in the tobacco sheets of examples 1 and 2, the production efficiency of cigarillos 11 can be improved as long as the baker smoothness can be improved.
The following conclusions can be drawn from the above-described embodiments, examples, comparative examples, and reference examples.
According to one embodiment, the tobacco sheet 21 contains 10 to 60 mass% of a tobacco material and 20 to 70 mass% of a cellulose fiber, has a thickness of 55 to 85 μm, and has a basis weight of 25 to 42g/m2The tensile strength is 12N/15mm or more. According to this structure, even when the tobacco sheet 21 is configured so that a predetermined amount of the tobacco material is contained in the cellulose-based fibers, the tensile strength can be maintained high. This makes it possible to use the tobacco sheet 21 as a structural material for a support structure for tobacco, for example, the wrapping paper 18 wrapped around the tobacco filler 17, the wrapping paper 16 covering the periphery of the filter body 15, and the tipping paper 14 joining the filter portions 13 of the tobacco rod 12. Alternatively, the tobacco sheet 21 can also be used as the tobacco filler material 17 that is difficult to deform.
According to a preferred embodiment, in the above embodiment, the stiffness of the tobacco sheet 21 is 15cm3And/100 or less. With this configuration, the stiffness of the tobacco sheet 21 can be reduced in a direction close to the stiffness of a typical cigarette wrapping paper. Therefore, when the tobacco sheet 21 is used for the above-described various wrapping papers (i.e., the wrapping paper 18, the wrapping paper 16, and the tipping paper 14), the shapes of various cylindrical structures (i.e., the tobacco rod 12, the filter unit 13, the cigarillo 11, or the cigarette) wrapped with the wrapping paper can be stabilized. Therefore, poor adhesion and cracks caused thereby in various cylindrical structures can be greatly prevented.
According to a preferred embodiment, in any of the above embodiments, the tobacco sheet 21 has a bakery smoothness of 15sec or more. With this configuration, the baker smoothness of the tobacco sheet 21 can be reduced in a direction close to the baker smoothness of a typical cigarette wrapping paper. Therefore, when the tobacco sheet 21 is used as the various wrapping papers (i.e., the wrapping paper 18, the wrapping paper 16, and the tipping paper 14), the tobacco sheet 21 becomes smooth, and the state of application of the adhesive and the adhesive strength at the overlapping portion between the end portions can be improved. This makes it possible to stabilize the shape of various cylindrical structures (i.e., the tobacco rod 12, the filter unit 13, the cigarillo 11, or the cigarette) wound with the wrapping paper. Therefore, poor adhesion and cracks caused thereby in various cylindrical structures can be greatly prevented.
According to a preferred embodiment, in any of the above embodiments, the tobacco sheet 21 is calendered. According to this structure, the thickness of the tobacco sheet 21 can be reduced by the calendering treatment, and the rigidity of the tobacco sheet 21 can be reduced. Further, the baker smoothness can be reduced by the calendering. Due to these factors, for example, when the tobacco sheet 21 is used as the various wrapping papers (i.e., the wrapping paper 18, the wrapping paper 16, and the tipping paper 14) described above, the application state and the adhesive strength of the adhesive at the overlapping portion between the end portions of the tobacco sheet 21 can be improved. This can stabilize the shape of various cylindrical structures (i.e., the tobacco rod 12, the filter unit 13, the cigarillo 11, or the cigarette) to be formed.
According to a preferred embodiment, in any of the above embodiments, the tobacco sheet 21 is a paper-made sheet. According to this configuration, since the tobacco sheet 21 can be formed by a general paper-making process, an existing paper-making apparatus used in the conventional production of the cigarette wrapping paper 18 can be directly used for the production of the tobacco sheet 21. Therefore, the cost required for providing the paper making device for manufacturing the tobacco sheet 21 can be reduced, and the cost required for manufacturing the tobacco sheet 21 can be reduced.
According to a preferred embodiment, in any of the above embodiments, the tobacco sheet 21 is a paper wrapper wrapped around the tobacco filler material 17. According to this structure, the tensile strength of the tobacco sheet 21 can be sufficiently increased, and therefore, even when the tobacco sheet 21 is used as the wrapping paper 18, breakage of the tobacco sheet 21 can be prevented.
As described above, by manufacturing the cylindrical structure using the tobacco sheet, it is possible to manufacture a cylindrical structure having the same thickness as that of a normal cigarette (that is, approximately the same thickness as that of a normal cigarette) without causing a burst roll25mm circumference) and can produce a cylindrical structure thinner than a normal cigarette without causing a burst roll. It is also possible to manufacture a cylindrical structure having a circumference of about 17mm, which is referred to as an ultra-thin dimension, in particular. That is, in the case of using the tobacco sheet, a smoking article having a circumference of 16mm to 27mm can be manufactured without causing a burst roll. In particular, the stiffness of the above tobacco sheet is 15cm3When the ratio is 100 or less, the tobacco sheet hardly rebounds during winding, and a thin cylindrical structure can be easily manufactured.
According to the above, the tobacco sheet can be applied to a conventional winder to manufacture a smoking article at high speed. Note that the so-called high-speed manufacturing is, for example, 5000cpm or more.
