Description

Roll paper for non-combustion heating type smoking article, and electric heating type smoking system
Technical Field
The present invention relates to a roll paper for a non-combustion heating type smoking article, and an electric heating type smoking system.
Background
Non-combustion heated smoking articles of the type which deliver volatile components to a user by heating from the surroundings of a tobacco rod (tobacco rod) containing cut tobacco are known. In the case of a non-combustion heating type smoking article, although the tobacco rod wrapped with the roll paper is heated, unlike the conventional cigarette, the tobacco rod does not burn and remains after use (after heating).
In the conventional cigarettes, white (colorless) paper is generally used as a wrapping paper for wrapping cut tobacco, although a logo or the like is sometimes provided.
Disclosure of Invention
Problems to be solved by the invention
It is known that when a roll paper used for a conventional cigarette is used as a roll paper of a wrapped tobacco in a non-combustion heating type smoking article, a color change may occur which is uncomfortable for the user due to heating during use.

< paper roll for non-combustion heating type smoking article >
In the present specification, the term "paper for non-combustion heating type smoking article" refers to paper for non-combustion heating type smoking articles described later. Hereinafter, the roll paper according to the embodiment of the present invention will also be simply referred to as "roll paper". As for the use of the roll paper according to the embodiment of the present invention, "for a non-combustion heating type smoking article" may be mentioned: a roll paper for a tobacco rod, which is used for producing a tobacco rod by wrapping a filler containing tobacco shreds; in order to connect members adjacent to the tobacco rod (for example, members constituting the mouthpiece) are used as tipping paper (tip paper) for wrapping the outer peripheral surfaces of the members.
The roll paper according to the embodiment of the present invention is a roll paper for a non-combustion heating type smoking article having a portion to which a thermosensitive material is added on one surface of the outer peripheral surface of the non-combustion heating type smoking article,
color difference DeltaE of a portion of the roll paper before heating to which the thermosensitive material is added and a portion of the roll paper after heating at 200 ℃ for 5 minutes * 15 or more. By generating such a color difference before and after heating, the uncomfortable color change that is generated in the non-combustion heating type smoking article in normal use can be made less noticeable.
In the roll paper according to the embodiment of the present invention, the portion to which the thermosensitive material is added is one surface of the non-combustion heating type smoking article as the outer peripheral surface. In other words, for example, when the roll paper according to the embodiment of the present invention is used as a roll paper for a tobacco rod, a heat-sensitive material is added to a surface which is not in contact with a tobacco filler described later. In addition, in the case where the roll paper according to the embodiment of the present invention is used as the tipping paper, a heat-sensitive material is added to a surface that is not in contact with a member (for example, a member of the mouthpiece portion) adjacent to the tobacco rod.
The portion to which the thermosensitive material is added may be present on the entire surface of the roll paper according to the embodiment of the present invention, or may be present at least in a portion to be heated (heating by an electric heating type device described later).
The proportion of the area of the portion to which the thermosensitive material is added to the total area of the roll paper is 1 to 50%. The proportion of the area of the portion to which the heat-sensitive material is added to the total area of the roll paper may be about 1 to 10% or about 1 to 5% in the case where the portion to which the heat-sensitive material is added is a portion such as a logo or a letter. In addition, in the mode in which the thermosensitive material is added to most of the portions of the roll paper that are heated, the thermosensitive material may be added to 40 to 50% of the area of the roll paper.
Examples of the thermosensitive material to be added to the roll paper according to the embodiment of the present invention include 1 or more selected from the group consisting of organic acids or salts thereof, monosaccharides, disaccharides, polysaccharides, and amino acids. In the case of using a plurality of combinations, examples thereof include: combinations of an organic acid or a salt thereof and at least 1 sugar selected from the group consisting of monosaccharides, disaccharides and polysaccharides (including combinations of an organic acid or a salt thereof and monosaccharides, combinations of an organic acid or a salt thereof and disaccharides, combinations of an organic acid or a salt thereof and polysaccharides), combinations of monosaccharides and amino acids, combinations of monosaccharides and polysaccharides, and the like. The following modes can be mentioned: these heat-sensitive materials are suitably dissolved in, for example, water to prepare an aqueous solution of the heat-sensitive materials, which is added to roll paper.
The concentration of the thermosensitive material in the preparation of the aqueous solution is not particularly limited, and examples thereof include 0.1 to 50% by weight, preferably 0.2 to 40% by weight.
The organic acid or a salt thereof includes at least 1 selected from acetic acid, potassium acetate, sodium acetate, citric acid, potassium citrate, sodium citrate, tartaric acid, potassium tartrate, sodium tartrate, phosphoric acid, sodium phosphate, potassium phosphate, malic acid, sodium malate, magnesium malate, lactic acid, and calcium lactate. It is considered that by using these organic acids or salts thereof, the amount of heat required for the oxidation reaction of the pulp of the roll base paper is reduced, and color development occurs.
The monosaccharide is preferably 1 or more selected from fructose, galactose and glucose. The disaccharide is preferably 1 or more selected from maltose, lactose and sucrose.
The polysaccharide is preferably at least 1 selected from carboxymethyl cellulose, carrageenan, pectin, and starch.
It is considered that when the above monosaccharides, disaccharides, and polysaccharides are used, color development due to caramelization reaction occurs.
The amino acid is preferably at least 1 selected from valine, leucine, isoleucine, glutamine, alanine, asparagine and arginine. It is considered that these amino acids develop color due to maillard reaction with carbonyl groups contained in pulp of roll paper base paper.
The aqueous solution of the thermosensitive material was transparent in appearance. In addition, when these heat-sensitive materials are added to the roll paper base paper, the color of the roll paper does not change. That is, the heat sensitive material is transparent in appearance before heating. Thus, the color that does not appear on the base paper of the roll paper before the use of the non-combustion heating type smoking article can be developed on the roll paper by heating at the time of use, and the color change of the base paper of the roll paper that is not caused by the development of the color of the heat-sensitive material can be made inconspicuous.
The content of the thermosensitive material in the roll paper according to the embodiment of the present invention may be 0.007mg/cm, based on the content of the portion to which the thermosensitive material is added 2 The above is preferably 0.07mg/cm 2 The above. On the other hand, as the upper limit value of the content of the thermosensitive material, for example, 7mg/cm may be mentioned in terms of the content of the portion to which the thermosensitive material is added 2 In the following, another example is 6mg/cm 2 In the following, another example is 5mg/cm 2 The following is given. By being in such a content range, it is possible to contribute to ΔE of the portion to which the thermosensitive material is added before and after heating * The value is 15 or more.
In the roll paper according to the embodiment of the present invention, Δe before and after heating is applied to the portion to which the thermosensitive material is applied * As the value of (2), 5 points in which a thermosensitive material was added to paper as a sample were measured, and the arithmetic average value was used. As a measurementThe object of (2) is to add an arbitrary portion of the paper to which the heat sensitive material is added, but when characters or patterns such as logos are present on the paper, the portion where such characters or logos are not present is the object. ΔE * The value may be determined by using a spectrophotometer.
Specifically, a spectrophotometer (manufactured by X-Rite corporation, trade name SpectroEye) was used. The measurement was performed by placing 1 sample on a paper having 92% ISO brightness under the conditions of light source D65, no light source filter, and a view angle of 2 °, and pressing a spectrophotometer thereon.
The method of adding the aqueous solution in which the thermosensitive material is dissolved to the roll paper base paper is not particularly limited, and examples thereof include coating, printing, and the like. The method of coating is not particularly limited. In the case of adding a heat-sensitive material to a roll paper base paper by printing, the above-described characteristics can be easily added to the roll paper.
The printing method is not particularly limited, and examples thereof include gravure printing and offset printing.
Printing may be exemplified by: the printing method is a method of printing on the entire surface of paper as a base paper, or at least a portion of the surface of the base paper heated by an electric heating device described later.
On the surface of the roll paper, it is preferable that at least a heated portion (a portion subjected to heating by an electric heating type device) has a color difference Δe before and after heating * 15 or more. In the surface of the roll paper, by providing the portion heated by an electric heating type device described later with the above-described characteristics, it is possible to prevent the impression of the heated appearance from deteriorating.
The shape of the roll paper for non-combustible smoking articles may be square or rectangular. In the case of using the paper as a roll for wrapping tobacco (for making a tobacco rod), the length of one side is about 19 to 70mm, the length of the other side is 15 to 26.5mm, and the preferable length of the other side is 24mm.
When a cigarette rod is wound by connecting the rod to another member adjacent to the rod like tipping paper, the length of one side is 20 to 60mm, and the length of the other side is 15 to 26.5mm.
The basis weight of the roll base paper according to the embodiment of the present invention is, for example, generally 20g/m 2 The above is preferably 35g/m 2 The above is more preferably 40g/m 2 The above. On the other hand, the weight per unit area is usually 65g/m 2 Hereinafter, it is preferably 50g/m 2 The following is given.
The thickness of the roll paper according to the embodiment of the present invention is not particularly limited, but is usually 10 μm or more, preferably 20 μm or more, more preferably 30 μm or more, and is usually 100 μm or less, preferably 75 μm or less, more preferably 50 μm or less, from the viewpoints of rigidity, air permeability, and ease of adjustment in paper making.
As a roll paper base paper according to an embodiment of the present invention, a paper having pulp as a main component is exemplified. The pulp may be a paper produced by mixing non-wood pulp, which is usually used for roll paper for smoking articles, such as flax pulp, hemp pulp, sisal pulp, spanish grass (esparto), and the like, in addition to pulp such as softwood pulp and hardwood pulp.
As the kind of pulp, chemical pulp, groundwood pulp, chemical groundwood pulp, thermomechanical pulp, and the like obtained by a sulfate cooking method (kraft cooking), an acidic/neutral/alkaline sulfite cooking method, a soda cooking method, and the like can be used.
As the pulp, for example, pulp composed of a mixed pulp of bleached pulp and unbleached pulp can be used.
In the case of using the mixed pulp, spruce as a conifer and aspen as a broadleaf tree were prepared as bleached pulp, and pine was prepared as unbleached pulp. The bleached pulp and unbleached pulp in the desired proportions are fed into a pulper to disintegrate the pulp. The dissociated pulp is then transferred to a refiner where it is beaten. Separately, calcium carbonate as a filler and a coagulant as a production aid were prepared and mixed with pulped pulp. The bleached pulp and the unbleached pulp may be separately disintegrated by using a plurality of pulpers, and pulped by using a refiner, and the bleached pulp, the unbleached pulp, the filler, and the manufacturing auxiliary agent, which are pulped, may be mixed in a mixing box.
Next, the mixed pulp is used to manufacture roll paper by adjusting the quality and uniformity in a paper making process using a fourdrinier, cylinder machine, cylinder short wire composite machine, or the like. The wet reinforcing agent may be added to impart water resistance to the roll paper and the sizing agent may be added to adjust the printing state of the roll paper, if necessary. Further, additives for papermaking such as aluminum sulfate, various anionic, cationic, nonionic or amphoteric yield improvers, drainage improvers, paper strength improvers and the like for papermaking and additives for papermaking such as dyes, pH adjusters, antifoaming agents, pitch control agents and residue control agents may be added.
When the bleached pulp and the unbleached pulp are used in combination, the ratio of the unbleached pulp in the roll paper is, for example, preferably 1% by weight or more and 90% by weight or less, more preferably 5% by weight or more and less than 86% by weight, and still more preferably 5% by weight or more and 60% by weight or less.
In addition to the above pulp, a filler may be contained in the roll base paper of the embodiment of the present invention. The content of the filler may be 30% by weight or more and less than 60% by weight relative to the total weight of the roll paper according to the embodiment of the present invention.
As the filler, calcium carbonate, titanium dioxide, kaolin, etc. can be used, and from the viewpoint of smoke smell, etc., calcium carbonate is preferably used.
Papers containing such fillers typically exhibit a bright color of the white series. On the other hand, roll paper made of mixed pulp generally has a color imparted by unbleached pulp.
As the roll paper base paper of the embodiment of the present invention, reconstituted tobacco (sheet tobacco) composed of reconstituted tobacco may be used.
As the reconstituted tobacco, there can be mentioned a papermaking reconstituted tobacco obtained by a papermaking method, and a slurry reconstituted tobacco obtained by drying a slurry.
Typical manufacturing methods for papermaking reconstituted tobacco may include: extracting natural tobacco materials (tobacco leaf, tobacco shred, vein, stem, root, etc.) with an extraction solvent such as water; a step of separating the extract and the residue obtained by the extraction operation; a step of making paper from the residue to produce a regenerated tobacco web; and pouring the extract subjected to the classification treatment as needed back to the regeneration net. Such a production method is described in, for example, international publication No. 2004/006001 as a wet papermaking method.
The slurry reconstituted tobacco can be produced by the method described in Japanese patent application laid-open No. 11-266851, for example. The raw stock slurry comprises wood pulp, tobacco powder and a binder which are mixed and defibrated in water. The raw stock slurry is extruded from a slurry feeder between a conveyor belt and a roller, and stretched into a sheet shape on the conveyor belt. Then, the sheet-like raw material slurry on the conveyor belt is conveyed to a drying furnace, and dried while passing through the drying furnace, thereby forming reconstituted tobacco.
When reconstituted tobacco is used as the base roll paper according to the embodiment of the invention, the basis weight thereof is 30 to 80g/m 2 The air permeability may be in the range of 0 to 60CU (CORESTA unit, cigarette paper air permeability unit).
As another method for producing reconstituted tobacco, there is a dry papermaking method described in japanese unexamined patent publication No. 61-52269, for example, in which reconstituted tobacco obtained by the former dry papermaking method is composed of wood pulp fibers, a binder and a stem portion of tobacco.
The roll paper according to the embodiment of the present invention may or may not contain a combustion improver contained in conventional roll paper for tobacco rods. The roll paper according to the embodiment of the present invention may be used as a first roll paper for use in a non-combustion heating type smoking article described later, or may be used as a second roll paper.
< non-combustion heating type smoking article >
As a non-combustion heating type smoking article according to an embodiment of the present invention, for example, an article having the structure of fig. 1 is cited.
The non-combustion heating type smoking article 10 of fig. 1 includes a filler 11, a tobacco rod portion formed by winding a first roll paper 12 of the filler 11, and a mouthpiece portion 16 constituting an end portion on the opposite side of the tobacco rod portion, and the tobacco rod portion and the mouthpiece portion are connected together by using a second roll paper 13 (tipping paper in fig. 1) which is the same as or different from the roll paper of the filler.
At least one of the first roll paper and the second roll paper is the roll paper according to the embodiment of the present invention described above. Preferably, at least the first roll paper is the roll paper of the embodiment of the present invention. In addition, it is also preferable that both the first roll paper 12 and the second roll paper are roll papers according to the embodiment of the present invention described above.
In the embodiment shown in fig. 1, the mouthpiece section 16 includes a paper tube section 14 and a filter section 15. Further, as the second roll paper for connecting them, a tipping paper 13 is provided. In fig. 1, the mouthpiece 16 is formed of 2 segments, and the mouthpiece 16 may be formed of a single segment or 3 or more segments. The segment constituting the mouthpiece portion may be constituted to include both the paper tube portion and the filter portion, or may be constituted only by one of them.
The vapor containing the aerosol-generating substrate and the tobacco flavor component generated by heating the tobacco rod is cooled by contact with the air in the paper tube as it passes through the paper tube portion 14, and is liquefied to generate an aerosol.
The non-combustion heating type smoking article 10 may have micropores (not shown) for allowing air from the outside to enter in a part of the paper tube portion 14 and the second roll paper 13 (tipping paper) surrounding the paper tube portion 14. By the presence of such micropores, air flows into the paper tube portion 14 from the outside during use, and the vapor containing the aerosol-generating substrate and the tobacco flavor component generated by heating the tobacco rod contacts with the air from the outside, thereby reducing the temperature, and liquefying the vapor to generate aerosol more reliably.
The paper tube portion 14 is, for example, a paper tube portion formed by processing thick paper into a cylindrical shape.
The filter portion 15 may be, for example, a filter portion using acetate tow as a material. The single filament fineness and the total fineness of the acetate tow are not particularly limited.
In fig. 1, the filter portion 15 is constituted by a single segment, but may be constituted by a plurality of segments. In the case of a plurality of segments, for example, a hollow segment is arranged on the upstream side, and the cross section of the mouthpiece is filled with acetate tow as a segment on the downstream side (the mouthpiece end side of the user). According to this aspect, unnecessary loss of the generated aerosol can be prevented, and the appearance of the non-combustion heating type smoking article can be improved.
In the manufacture of the filter, the air permeation resistance can be adjusted and additives (known adsorbents, flavors, flavor-retaining materials, etc.) can be added.
The material of the second roll paper 13 (tipping paper) is not particularly limited, and a roll paper of an embodiment of the present invention may be used in part or all. Examples of the second roll paper 13 include: after the wrapping, the tobacco rod, paper tube portion 14 and filter portion 15 are fixed around them with a vinyl acetate based adhesive.
The tobacco rod includes cut tobacco as the filler 11, and the material of the cut tobacco is not particularly limited, and known materials such as lamina and vein can be used.

Examples
The present invention will be described more specifically with reference to examples, but the present invention is not limited to the following examples without departing from the spirit thereof.
< preparation of paper sample >
A commercially available roll paper for tobacco rods was cut into 5cm by 5cm pieces.
As the heat-sensitive material, the substances shown in table 1 below were selected, and aqueous solutions of the respective substances were prepared at the concentrations shown in table 1. Each aqueous solution was applied to the cut roll paper with a width of 3cm using a brush pen.
As a control, a roll paper was used, which was not coated with any substance on the cut roll paper. In the commercially available roll paper for tobacco rods, citric acid (shown in table 1 as a coating amount, but not coated) was contained as a combustion improver in an amount of about 1.2% by weight based on the total amount of the roll paper.
Further, a commercially available roll paper for self-extinguishing tobacco rods (a self-extinguishing agent is coated on a surface in contact with tobacco shreds) was prepared as comparative example 1.
For each sample, the sample was placed on a household aluminum foil (material: aluminum foil thickness: 11 μm), and heated at 200℃for 5 minutes in a muffle furnace (product name: model Muffle Furnace FO, manufactured by Yamato Scientific).
< measurement of color difference >
For each sample before and after heating, ΔE was measured using a spectrophotometer (manufactured by X-Rite corporation, trade name SpectroEye) * . The measurement was performed by placing 1 sample on a paper having 92% ISO brightness under the conditions of light source D65, no light source filter, and a view angle of 2 °, and pressing a spectrophotometer thereon.
For the portion coated with the thermosensitive material, measurement was repeated at 5 sites, and the average value was used for analysis.
The results of the color difference measurement are shown in table 1.
TABLE 1
From the results of Table 1, it was found that the sample obtained by applying the aqueous solution containing the substances shown in Table 1 as the heat-sensitive material to the roll paper had a color difference ΔE before and after heating at 200℃for 5 minutes * At least 15, in contrast to the color difference ΔE of control, comparative example 1 * Less than 15. In addition, for the color difference delta E * For samples of 15 or moreIn other words, the difference ΔE between before and after heating is used * The discoloration was observed to a degree of 15 or more, but the test piece was not perceived as an uncomfortable color even after heating by the panelist.
On the other hand, for the color difference ΔE * As a result of observation by the panelists of the control and comparative example 1, which was smaller than 15, the appearance after heating gave a slightly unpleasant impression as compared with that before heating.
