Chip paper for tobacco products with capsule filters and tobacco products

The present invention relates to a chip paper for a tobacco product with a capsule filter and a tobacco product.

Tobacco products consisting of a tobacco rod part with a tobacco engraving, a mouthpiece part with a filter, and members such as chip paper for wrapping these are cigarettes (cigarettes) and cigarettes that have been used for many years. It has been attracting attention as a substitute in recent years, and is used in tobacco flavor suction articles for electrically heated tobacco products that utilize electric heating without burning.
Ordinary cigarettes (cigarettes) are made by chopping dried tobacco leaves to a width of about 1 mm, adding fragrances, moisturizers, and appropriate moisture, and wrapping them in a cylinder with a wrapper made mainly of paper. It is made by connecting a rod and a mouthpiece rod made by winding fibers made of cellulose acetate or folds in a columnar shape with a wrapper made of paper, and connecting them with lining paper at the ends. ing. When using a normal cigarette, the user ignites the end of the tobacco rod with a lighter or the like and smokes by sucking from the end of the mouthpiece. The fire part at the tip of the tobacco rod burns at a temperature exceeding 800 ° C.
On the other hand, a normal heat-not-burn tobacco product comprises a cylindrical cigarette flavor suction article for a cylindrical heat-not-burn tobacco product similar to a normal cigarette, and a heating device having a battery, a controller, a heater, and the like. There are two types of heaters, one is by electric resistance and the other is by IH. For the heater by electric resistance, the contact point with the non-combustion heating type tobacco flavor suction article should be heated from the outside of the columnar non-combustion heating type tobacco flavor suction article. In some cases, needle-shaped or on a blade is inserted into the tobacco filling layer from the tip of a non-combustion-heated tobacco flavor suction article.

Tobacco flavor suction articles for general cigarettes and electrically heated tobacco products contain a flavor component in the tobacco rod portion, and the user can obtain various flavors by sucking the flavor component at the time of use. .. However, there is a need for users who want a flavor that is higher than the flavor derived from the flavor component contained in such a tobacco rod portion, and one of the means for meeting this need is a capsule filter. The capsule filter is a filter containing a crushable outer shell and containing a capsule containing a flavor component inside the outer shell, and the user crushes the capsule at the time of use to obtain the flavor in the capsule. By releasing the component, it is possible to obtain a flavor higher than that derived from the flavor component contained in the tobacco rod portion. For example, Patent Documents 1 to 3 disclose a technique for a tobacco product with a capsule filter.

The air permeability of the paper layer 12 is not particularly limited, but is usually 0 cholesterol unit or more and 400 cholesterol units or less, preferably 3 cholesterol units or more and 100 cholesterol units or less, and 5 cholesterol units or more. More preferably, it is 10 or less cholester units. The air permeability as used herein refers to the air flow rate perminished (permeated) per minute and 1 cm ² when air is passed through one side (2 cm ² ) of paper under a constant pressure of 1 kPa.

The paper layer 12 may contain a filler in addition to the above pulp, and may contain, for example, calcium carbonate (CaCO ₃ ), a metal carbonate such as magnesium carbonate, or a metal such as titanium oxide, titanium dioxide, or aluminum oxide. Examples thereof include oxides, metal sulfates such as barium sulfate or calcium carbonate, metal sulfides such as zinc sulfide, aluminum hydroxide (Al (OH) ₃ ), quartz, kaolin, talc, caestic soil, and gypsum. In particular, from the viewpoint of improving whiteness and opacity and increasing the heating rate, it is preferable to contain one or more selected from CaCO ₃ , kaolin, talc, and Al (OH) ₃ . In addition, these fillers may be used alone or in combination of two or more.
The content of the filler in the paper layer 12 is not particularly limited, but is usually 1% by weight or more and 50% by weight or less, preferably 5% by weight or more and 40% by weight or less, and 10% by weight or more and 30% by weight. It is more preferably 0% by weight or less. If it is below the lower limit of the above range, the chip paper 14 tends to be vulnerable to heat, and if it exceeds the upper limit, the strength of the chip paper 14 is greatly reduced and the hoistability may be deteriorated.

In addition to the above-mentioned pulp and filler, various auxiliaries may be added to the paper layer 12, and for example, the paper layer 12 may have a water resistance improving agent in order to improve the quality. The water resistance improver includes a wet paper strength enhancer (WS agent) and a sizing agent. Examples of the wet paper strength enhancer include urea formaldehyde resin, melamine formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol having a saponification degree of 90% or more.

As an auxiliary agent, a paper strength enhancer may be added, and examples thereof include polyacrylamide, cation starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, and the like. In particular, it is known that the air permeability of oxidized starch is improved by using a very small amount (Japanese Unexamined Patent Publication No. 2017-21869).

[Manufacturing method of chip paper]
The method for producing the chip paper 14 is to use any other layer such as the CaCO ₃ containing layer 11, the paper layer 12, the oil resistant layer 13, and the adhesive layer 15 as described above, and the CaCO ₃ containing layer 11, the paper layer 12, and the oil resistant layer 14. As long as the sex layers 13 are laminated in this order and the CaCO ₃ -containing layer 11 and the paper layer 12 can be laminated so as to be adjacent to each other, the known method can be applied without particular limitation. As an example of the method for producing the chip paper 14, the method for producing the chip paper 14 including the CaCO ₃ containing layer 11, the paper layer 12, the adhesive layer 15, and the oil resistant layer 13 shown in FIG. 1 (c) is shown below.

Then, a solution containing at least CaCO ₃ and any other components that could be contained in the CaCO ₃ containing layer, and any solvent were prepared (CaCO ₃ containing solution preparation step), which was prepared in the paper layer preparation step. It is applied to the paper layer 12, dried, and the CaCO ₃ containing layer 11 is laminated on the paper layer 12 to obtain a laminated body (CaCO ₃ containing layer forming step). The solvent is not particularly limited as long as it can dissolve various raw materials that can be used in the solution.
The temperature at which the CaCO ₃ containing solution is dried is usually more than 100 ° C, preferably more than 140 ° C, more preferably more than 150 ° C, still more preferably more than 170 ° C, and usually more than 300 ° C. It is less than ° C., preferably less than 250 ° C., more preferably less than 200 ° C.
Further, the CaCO ₃ containing solution may be dried while pressurizing with a press machine provided with a cylinder or the like, whereby the water content in the paper layer can be removed.
Further, as the above-mentioned drying, or as a treatment for the laminated body of the paper layer and the CaCO ₃ -containing layer finally obtained separately from this drying, a calendar treatment may be performed using a calendar roller or the like.

(Lamination of paper layer, adhesive layer, and oil resistant layer)
A solution containing components that can be contained in the adhesive layer and an arbitrary solvent is prepared (adhesive layer material-containing solution preparation step). Then or at the same time, a solution containing the components constituting the oil resistant layer and an arbitrary solvent is prepared (step of preparing a solution containing an oil resistant layer material), and a film is prepared from the solution by an arbitrary method (oil resistant film). Fabrication step). Then, the laminate obtained in the above-mentioned CaCO ₃ -containing layer forming step is prepared, the above-mentioned adhesive layer material-containing solution is applied to the paper layer 12 on the opposite surface to the CaCO ₃ -containing layer 11, and the mixture is appropriately dried. The adhesive layer 15 is laminated on the paper layer 12 to obtain a laminated body (adhesive layer forming step). The above oil-resistant film is brought into contact with the adhesive layer 15 before it is completely dried, the adhesive layer 15 which has not been dried, or the adhesive layer 15 which has been completely dried and then melted again by heating or the like to have oil resistance. The layers 13 are laminated to obtain a final laminated body (chip paper 14) (oil resistant layer laminating step). Further, in the oil resistant layer 13, the raw material of the oil resistant layer 13 is applied to the adhered surface of the layer to which the oil resistant layer 13 is adhered, and specifically, the raw material of the oil resistant layer 13 is applied by a printing method such as gravure printing.

As used herein, "arranged concentrically" means that the centers of all tobacco sheets are arranged so as to be substantially in the same position. In the present invention, the "sheet" refers to a shape having a pair of substantially parallel main surfaces and side surfaces. The second filling is composed of a plurality of tobacco sheets wound concentrically in a direction orthogonal to the longitudinal direction of the tobacco product 10.
Examples of the sheet base material include tobacco materials such as tobacco powder, and tobacco materials are particularly preferable. It is preferable that the base sheet of the tobacco material is a tobacco sheet in which a component capable of generating a flavor is supported, if necessary.
The tobacco sheet may contain an aerosol-forming substrate that produces aerosol smoke upon heating. An aerosol source such as a polyol such as glycerin, propylene glycol, or 1,3-butanediol is added as an aerosol-forming substrate. The amount of the aerosol-forming substrate added is preferably 5% by weight or more and 50% by weight or less, and more preferably 15% by weight or more and 25% by weight or less with respect to the dry weight of the tobacco sheet.

The tobacco sheet as a material before being arranged concentrically will be described.
The tobacco sheet can be appropriately produced by a known method such as papermaking, slurry, rolling, or the like. It should be noted that the homogenizing sheet described in the first tobacco filling can also be used.
In the case of papermaking, it can be manufactured by a method including the following steps. 1) Dried tobacco leaves are coarsely crushed, extracted with water and separated into a water extract and a residue. 2) The water extract is dried under reduced pressure and concentrated. 3) Pulp is added to the residue, fiberized with a refiner, and then made into paper. 4) Add a concentrated solution of water extract to the paper-made sheet and dry it to make a tobacco sheet. In this case, a step of removing a part of the components such as nitrosamine may be added (see Japanese Patent Publication No. 2004-510422).
In the case of the slurry method, it can be produced by a method including the following steps. 1) Mix water, pulp and binder with crushed tobacco leaves. 2) The mixture is thinly spread (cast) and dried. In this case, a step of removing some components such as nitrosamines by irradiating a slurry obtained by mixing water, pulp and a binder with crushed tobacco leaves with ultraviolet rays or X-rays may be added.

In addition, as described in International Publication No. 2014/104078, a non-woven fabric-like tobacco sheet produced by a method including the following steps can also be used. 1) Mix the powdered tobacco leaves and the binder. 2) The mixture is sandwiched between non-woven fabrics. 3) The laminate is formed into a constant shape by heat welding to obtain a non-woven fabric-like tobacco sheet.
As the type of the raw material tobacco leaves used in each of the above methods, the same types as those described in the first filling can be used.
The composition of the tobacco sheet is not particularly limited, but for example, the content of the tobacco raw material (tobacco leaf) is preferably 50% by weight or more and 95% by weight or less with respect to the total weight of the tobacco sheet. Further, the tobacco sheet may contain a binder, and examples of the binder include guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose) and the like.

Examples of the additive include a filler such as pulp. Although a plurality of tobacco sheets are used in the present invention, all of the tobacco sheets may have the same composition or physical properties, or some or all of the tobacco sheets may have different compositions or physical properties.

For the second tobacco filling, a plurality of tobacco sheets having different widths are prepared, a laminated body is prepared in which the width decreases from the bottom to the top, and this is passed through a winding tube and rolled up. Can be manufactured by According to this manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Further, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost layer of the tobacco sheet.
In this manufacturing method, it is preferable that the laminate is prepared so that a non-contact portion is formed between the adjacent tobacco sheets after the winding molding.
If there is a non-contact portion (gap) between the plurality of tobacco sheets that the tobacco sheet does not contact, the flavor flow path can be secured and the delivery efficiency of the flavor component can be enhanced. On the other hand, when the tobacco product is used in the electrically heated tobacco product, the heat from the heater can be transferred to the outer tobacco sheet through the contact portions of the plurality of tobacco sheets, so that high heat transfer efficiency can be ensured.

In order to provide a non-contact portion between a plurality of tobacco sheets so that the tobacco sheets do not come into contact with each other, for example, an embossed tobacco sheet is used, and adjacent tobacco sheets are laminated without adhering the entire surfaces of the adjacent tobacco sheets. A method of preparing a laminate by adhering a part of each other and laminating, or by slightly adhering and laminating the entire surface or a part of adjacent tobacco sheets so as to be peeled off after winding molding can be mentioned. ..
When preparing the tobacco rod portion including the wrapping paper, the above-mentioned wrapping paper may be arranged at the bottom of the laminated body.
Further, a fitting portion can be formed by placing a tubular dummy such as a mandrel on the uppermost portion of the laminated body to form a second tobacco filler and then removing the dummy.
The thickness of each tobacco sheet is not limited, but is preferably 150 μm or more and 1000 μm or less, and more preferably 200 μm or more and 600 μm or less, from the viewpoint of heat transfer efficiency and strength. The thickness of each tobacco sheet may be the same or different.
The number of tobacco sheets constituting the second tobacco filler is not particularly limited, and examples thereof include 2, 3, 4, 5, 6, or 7 sheets.

[Sample preparation]
(1) Paper layer A base paper (flame-retardant water-resistant paper manufactured by Feurstein) having the characteristics shown in Table 1 (hereinafter, also simply referred to as “base paper”) was used.
(2) Laminated body consisting of CaCO ₃ -containing layer and paper layer A solution containing calcium carbonate and a binder is prepared on the above paper layer, the solution is applied so that the weight per unit surface area is 13 gsm, and the solution is dried. Then, a laminated body of a CaCO ₃ containing layer and a laminated body of a paper layer (hereinafter, also referred to as “laminated body 1”) were obtained. The characteristics of the laminated body 1 are shown in Table 1.
(3) Laminated body composed of CaCO ₃ containing layer, paper layer, adhesive layer, and oil resistant layer An oil resistant layer having a Kit value of 12 can be obtained on the surface of the above laminated body 1 on the paper layer side. After applying the oil-resistant material-containing solution, the mixture was dried to obtain a laminate composed of a CaCO ₃ -containing layer, a paper layer, an adhesive layer, and an oil-resistant layer (hereinafter, also referred to as “laminate 2”). The characteristics of the laminated body 2 are shown in Table 1.

[Evaluation characteristics]
(Whiteness, opacity)
The whiteness and opacity of the base paper were evaluated on one side, and the whiteness and opacity of the

laminated bodies

1 and 2 were evaluated on the surface on the CaCO ₃ containing layer side. Specifically, the whiteness and opacity were measured using a whiteness / opacity measuring machine (manufactured by Murakami Color Technology Research Institute, model number: WMS-1) in accordance with ISO2470 and ISO2471, respectively.

(Glossiness)
The glossiness of the base paper was evaluated on one side, and the glossiness of the

laminated bodies

1 and 2 was evaluated on the surface on the CaCO ₃ containing layer side. Specifically, Gloss Checker IG-331 (manufactured by HORIBA) was used to evaluate the incident angle and the glossiness of the light receiving angles of 20 degrees and 60 degrees based on the provisions of ISO8254-1: 2009, respectively.

(Tensile strength, elongation)
Using the base paper, the laminated body 1 and the laminated body 2, the tensile strength and the elongation were measured with a width of 15 mm using a tensile tester EL (manufactured by Toyo Seiki Co., Ltd.) based on JIS P 8113.

(Surface smoothness)
The glossiness of the base paper was evaluated on one side of the

laminated body

1 and 2 on the surface of the CaCO ₃ -containing layer side using a Bekk smoothness tester.

(Kit value)
For the base paper, the Kit value was evaluated on one side of the

laminated body

1 and 2 on the side opposite to the side on which the CaCO ₃ containing layer was present. Specifically, JAPAN TAPPI pulp and paper test method No. The Kit value was measured according to 41: 2000 "Paper and Paperboard-Holidity Test Method-Kit Method".

[Experiment 1: Evaluation of sharpness of decoration]
The sharpness of the decoration was evaluated using the above-mentioned base paper and the laminated body 1. Specifically, after printing (gravure printing) with ink (silver ink manufactured by Tokyo Ink Co., Ltd.) on one side of the base paper and on the side of the CaCO ₃ containing layer for the laminate 1. The printed surface was observed with an optical microscope, and the sharpness of the decoration with ink was evaluated. The evaluation results are shown in FIG.
From FIG. 11, it was found that the laminate 1 having the CaCO ₃ containing layer had clearer characters and lines than the base paper. It is considered that this is because it is smooth and prevents silver ink particles from entering the inside of the paper.

[Experiment 2: Oil stain evaluation]
Oil stains were evaluated using the above-mentioned base paper, laminate 1, and laminate 2. Specifically, 0.15 mL of medium-chain fatty acid triglyceride (MCT) is dropped on one side of the atom, on the paper layer side of the laminate 1, and on the oil-resistant layer side of the laminate 2. After that, the degree of diffusion of MCT was evaluated 1 minute and 5 minutes (corresponding to normal smoking time) and 10 minutes after the dropping. MCT is a component contained in a capsule of a general capsule filter, and 0.15 mL corresponds to the amount of two capsules. The degree of diffusion of MCT was calculated as the average value of the shortest diameter and the longest diameter evaluated from the shape of the spread of MCT at the time of evaluation. In addition, a photograph showing the degree of diffusion of MCT after 10 minutes is shown in FIG. Regarding the photograph of the laminated body 2 in FIG. 12, the MCT did not soak into the laminated body at all, and the MCT flowed on the laminated body. Therefore, after performing the above evaluation, the MCT on the laminated body was wiped off. , This is a picture taken.
In addition, the opacity before the addition of MCT and 5 minutes after the addition of MCT (0.01 ml / cm ² ), and the change in these opacity (after the addition of MCT-before the addition of MCT) were evaluated. The opacity was evaluated by the same method as described above.
The evaluation results of MCT are shown in Table 2 below, and the evaluation results of opacity are shown in Table 3 below. The evaluation result was calculated as an average value of n = 3.

From FIG. 12 and Table 2 above, the degree of MCT diffusion was not so different between the base paper and the laminate 1, but the degree of diffusion was lower in the laminate 2 having the oil resistant layer than in these samples. Do you get it. It is considered that this is because the sample diffusion was suppressed by the oil resistant layer.
Regarding the opacity, it was found from Table 3 above that the laminate 1 having no oil resistant layer but having a CaCO ₃ containing layer had lower transparency than the base paper, and the laminate 2 having an oil resistant layer had an opacity. It turned out that the transparency can be maintained. It is considered that this is because the oil-resistant layer suppresses the penetration of the sample.
Therefore, it was found that the laminated body 2 which is the chip paper according to the present embodiment can suppress the diffusion of MCT and further suppress the decrease in transparency.

Based on the above experimental results, according to the present invention, for tobacco products with a capsule filter, which can suppress stains on the surface of chip paper derived from the components in the capsule contained in the capsule filter and can give a clear decoration to the surface. It can be seen that chip paper and tobacco products having the chip paper can be provided.
