In the present invention, the so-called "scented tasting article" refers to an article that a user uses to inhale scents. Among the flavored tasting articles, those having tobacco or components derived from the tobacco are referred to as "tobacco flavored tasting articles". Tobacco flavored smoking articles can be roughly divided into "burning tobacco flavored smoking articles" (also referred to as "smoking articles") that produce flavor by burning, and "non-combustion tobacco flavoring articles" that do not burn to produce flavor. Grass-scented tasting items". Furthermore, the non-combustion tobacco flavor inhalers are roughly classified into "non-combustion heated tobacco flavor inhalers" that generate flavor by heating, and "non-combustion non-heated tobacco flavor inhalers" that generate flavor without heating. tasting items".

1. Fragrance-tasting article filter sheet

The sheet system for a flavor absorbent article filter contains fibers, particles having a particle size of 20 to 200 meshes, and an adhesive, so that the particles are made uneven in the thickness direction.

(1) Particles

The particles contained in the fragrant tasting article filter sheet have a particle size of 20 to 200 mesh. Too small a particle size becomes difficult to handle. In addition, when the particle size is too large, it is difficult for the particles to remain in the interior of the sheet, and most of the particles are present on the surface of the sheet. As a result, when a filter is manufactured using the sheet, the particles on the surface of the sheet come into contact with the surface of the device at a high speed, damage the surface of the device, or the mechanical properties of the sheet may be degraded due to particles falling off the sheet. From this viewpoint, the lower limit value of the aforementioned numerical range is preferably 28 meshes or more, and more preferably 70 meshes or more. The upper limit of the aforementioned numerical range is preferably 150 meshes or less. Particles with a mesh size of 28 or more are preferably embedded in the smoking article filter sheet body easily.

The particles are not limited as long as they are used in the field of flavor-absorbing articles, but are preferably adsorbents or ingredient-releasing agents. The so-called adsorbent is a material for adsorbing a part of a component generated from an aroma-inhaling article, and examples thereof include porous materials such as activated carbon and zeolite, and polar group-containing materials such as cellulose. The so-called ingredient release agent is a material that contains a substance and a carrier carried in a manner that can release the substance, or a material that itself releases the substance. Among the former, the substance system includes fragrances such as camphor alcohol, and the carrier system includes clathrate compounds such as cyclodextrin, and porous materials such as calcium carbonate and alumina. Examples of the latter include mint leaf particles obtained by pulverizing mint leaves, or pulverized smoke. Tobacco particles obtained from grass plants, etc. Mint leaf particles will release menthol, etc., and tobacco particles will release aroma. The whole particle can be composed of an adsorbent or a component releasing agent, or a part of the whole particle can be composed of an adsorbent or a component releasing agent. In the latter, the lower limit of the total amount of the adsorbent and the component releasing agent in the whole particle is preferably 80% by weight or more, more preferably 90% by weight or more, and still more preferably 95% by weight or more. Moreover, the upper limit is preferably 99% by weight or less, more preferably 98% by weight or less.

(2) Fiber

The fiber is not limited as long as it can form the matrix of the sheet body for the filter of the flavored absorbent article. For example, synthetic fibers or semi-synthetic fibers using cellulose acetate, PP, PE, PET, polylactic acid, etc. as raw materials can be mentioned. Moreover, although natural fibers, such as a plant fiber using cellulose etc. as a raw material, are mentioned, from a viewpoint of reducing an environmental load, a natural fiber is preferable. The length of the fibers is not particularly limited, but in order to form the matrix of the sheet body, shorter fibers are preferred, and the fiber length is preferably 5 mm or less. The fineness of the fibers is not particularly limited, but the single fineness of synthetic fibers or semi-synthetic fibers is preferably 1 to 30 (denier/silk), more preferably 1 to 10 (denier/silk). In the case of natural fibers, the thickness can be used as an indicator of thickness and length. From the viewpoint that the ventilation resistance suitable for inhalation can be more easily achieved, the thickness is preferably 0.15 to 0.25 mg/m, more preferably 0.16 to 0.24 mg/m, and 0.18 to 0.22 mg/m For better. This thickness is measured according to JIS P 8120:1998.

The cross-sectional shape of the fibers when using synthetic fibers or semi-synthetic fibers is not limited, but an R shape or a Y shape is preferable, and a Y shape is more preferable from the viewpoint of cost. In addition, when the sheet is formed, a plasticizer or a binder may be used in order to increase the strength of the sheet by adhering to the contact points of the fibers and the fibers. When natural fibers such as cellulose are used, water-soluble binders such as starch, modified starch, modified cellulose, PVA, or PVAc can be used alone or in combination, and latex or the like can also be used. Use acetate fiber As fibers, the aforementioned binders for natural fibers can be used, and a plasticizer (triacetin) having the ability to dissolve cellulose acetate can also be used.

Among them, natural fibers are preferred from the viewpoint of less environmental load than synthetic fibers or semi-synthetic fibers, and wood pulp fibers are particularly preferred from the viewpoint of excellent heat resistance. In this case, the weight of the wood pulp fibers per unit area of the sheet is 25 to 50 g from the viewpoint of suitability for manufacture when the sheet is processed into a filter, or the rod hardness after the filter is processed. /m ² is preferred.

(3) Adhesive

A well-known thing can be used for a next agent system. Among them, the adhesive is preferably selected from the group consisting of polyvinyl alcohol, vinyl acetate acrylic copolymer, or a mixture of these from the viewpoints of less influence on the taste and aroma of the flavored article and excellent heat resistance. The weight of the adhesive (solid weight) is preferably 4 to 40 g/m ² per unit area of the sheet. When the amount of the follow-up agent is too large, it becomes unfavorable to the economy, and there is a risk of affecting the flavor. In addition, when the amount is too small, there are few bonding points between fibers, and the fibers are scattered, resulting in inconveniences such as failure to maintain the tensile strength of the sheet.

(4) Distribution rate of particles

The particles are distributed in the flavored absorbent article filter sheet according to the following distribution rates. The distribution ratio will be described with reference to FIG. 1 . Fig. 1 is a cross-section showing a sheet body for a filter for a flavored inhalation article. In the figure, 1 is a filter sheet for flavor and taste articles, 13 is particle, 15 is fiber, A is one side, a is the area from the center in the thickness direction to one side, B is the other side, and b is from the thickness direction. The area from the center to the other side. The distribution ratios CA and CB are defined as follows.

CA = weight of particles present in area a / weight of all particles

CB=weight of particles present in region b/weight of total particles

The particles are distributed in the flakes in such a way that CA>CB. CA:CB is preferably 60 to 100: 0 to 40, more preferably 70 to 90: 10 to 30.

The total weight of the particles is preferably 7 to 80 g/m ² per unit area, and more preferably 10 to 40 g/m ² , per unit area of the fragrant inhalation article filter sheet. When the weight of the particles does not reach the lower limit value, the function of the particles cannot be fully exhibited, and when the weight exceeds the upper limit value, it becomes unfavorable for economical efficiency.

It is preferable that the particle distribution ratio in the vicinity of the surface layer of the sheet body for a flavor absorbent article filter is low. When there are many particles in the vicinity of the surface layer of the sheet body for a flavor-absorbing article filter, there is a risk of damage to the manufacturing apparatus during manufacture. From such a viewpoint, it is defined as follows, the distribution ratio CAs in the vicinity of the surface layer of the particle is preferably 0 to 10, more preferably 0 to 5, still more preferably 0 to 3, and the distribution ratio CBs is preferably 0 to 3 0 to 5, preferably 0 to 3, still more preferably 0 to 1. From the viewpoint of protecting the manufacturing device, it is more preferable that both CAs and CBs are 0, and when both CAs and CBs are not 0, it is preferable that the particles are embedded in the body of the filter sheet for flavor inhalation articles.

CAs=weight of particles present in a region from one surface (face A) to 5% in thickness direction/weight of total particles

CBs=weight of particles present in the region from the other surface (face B) to 5% in the thickness direction/weight of total particles

These distribution ratios can also be obtained by image analysis of the cross-section of the filter sheet for flavored inhalants, and can also be found in the 5% portion of the filter sheet for flavored inhalants from the center in the thickness direction or the surface. It is obtained by dividing the surface parallel to the main surface and measuring the weight of the particles and the flakes. From the viewpoint of simplicity, the former method is preferable. The distribution rate in the filter body of the aroma-tasting article is given by Since the surface direction is uniform, in this method, the distribution ratio of the entire sheet can be obtained by image analysis of a cross-section of the sheet for the filter for flavor-absorbing articles.

(5) Shape, etc.

The shape can be appropriately adjusted according to the application. For example, in the case of a cylindrical fragrance inhalation filter having a diameter of 24 mm and a height of 27 mm, the shape of the fragrance inhalation filter sheet is about 27 mm in length, 50 to 150 mm in width, and 0.8 to 2.0 mm in thickness. The thickness can be measured by optical measurement such as image analysis of the cross section of the sheet body. Moreover, it can also measure using the thickness measurement method of paper and cardboard shown in JISP8118:2014. The apparent density of the fragrant absorbent article filter sheet is also not limited, but in one aspect is 30 to 200 g/m ³ . The apparent density as used herein can be calculated by dividing the basis weight of the sheet including all the fibers, binders, and particles that belong to the constituent elements of the sheet by the volume of the sheet.

2. Manufacturing method

Although the sheet body for a flavor-smell-good filter can be manufactured by any method, it is preferable to manufacture it by the method which has the following steps.

Step 1: On the mesh that is sucked from the back, place fibers to form a sheet;

The mesh is not limited as long as it is used in the manufacture of nonwoven fabrics, and for example, a wire mesh etc. are mentioned. The loaded fibers are fixed by sucking the mesh from the back. This step is preferably carried out by blowing the fibers onto the aforementioned mesh using gas as a medium. Air can be used as the gas.

(2) Step 2

In this step, an adhesive is added to one side A of the sheet body 10 . The adhesive is as described above, and the amount is appropriately adjusted, but considering the amount of the adhesive added on the other side B, the final sheet body is adjusted in such a way that the weight of the solid content of the adhesive is about 4 to 40 g/m ² . The amount contained per unit area. For example, an adhesive agent of about 2 to 20 g/m ² can be added to face A, and an adhesive of about 2 to 20 g/m ² can be added to face B in step 4. The adhesive feeder 33 is preferably sprayed, and the adhesive is preferably sprayed. The sheet 10 to which the adhesive is added is transferred to the sheet conveyor 5, and is preferably dried. The drying system can be implemented using the dryer 55 or by air-drying. As the sheet conveyor system, for example, a conveyor belt can be used. In this step, an adhesive is applied to the surface A, and fibers are fixed to each other.

(3) Step 3

In this step, the sheet body 10 obtained in step 2 is turned over. Specifically, by transferring the sheet 10 from the sheet conveyor 5 to the sheet conveyor 7, it is turned so that the surface B faces the direction on the paper surface.

(4) Step 4

In this step, the above-mentioned particles and the adhesive are simultaneously added to the other side B of the sheet body 10, or the adhesive is added after the above-mentioned particles are added. FIG. 2 shows a state in which particles are supplied from the particle feeder 71 on the surface B of the sheet body 10 , and then the adhesive is sprayed from the adhesive feeder 73 . It is also possible to supply the adhesive and the particles at the same time. The agent feeder 73 is preferably sprayed as described above. The amount of the adhesive added in this step is as described above, and is adjusted so that the final weight of the solid content of the adhesive is about 4 to 40 g/m ² . The amount of particles is appropriately adjusted in such a way as to achieve the desired amount. The 1-series particles of the sheet body for a filter for smoking article manufactured in this way are mostly present on the surface A side.

(5) Drying step

In the present production method, a drying step may be provided at any position. FIG. 2 shows an aspect in which a drying step for drying the aforementioned sheet is provided between steps 2 and 3 and after step 4. As shown in FIG. This aspect is suitable when a water-soluble adhesive is used. The drying system can be carried out by air drying. In addition, when the latex is used as the adhesive, air drying is performed without a drying step using a dryer, or a drying step may not be provided.

3. Fragrance tasting items

A flavored inhalation filter is prepared from a flavored inhalation filter sheet. The preparation method is not limited and can be carried out by a known method, but for example, the cut sheet body for a filter for an aroma inhalation article can be rolled up to form a cylindrical shape; or as shown in FIG. 3 , a plurality of cut pieces can be for the filter of scented items The sheet body 1 is overlapped, and is folded so that the cross section of the sheet body draws an S shape, and is filled in the covering body to form a cylindrical shape, thereby forming the filter segment 100 . The method of FIG. 3 can be implemented, for example, as described in Japanese Patent Publication No. Sho 44-3727. The filter segment can be combined with other segments, such as the flavor generating segment, to produce a combustion-type tobacco flavoring article, or a non-combustion-type tobacco-flavoring article, particularly, a non-combustion heating-type tobacco flavoring article.

(1) Combustion-type tobacco flavor tasting articles

An example of a combustion type tobacco flavor tasting article is shown in FIG. 4 . As shown in FIG. 4 , the combustion-type tobacco flavor tasting article 240 includes: a tobacco rod portion 250 , a second filter section F2 and a first filter section F1 disposed adjacent to the tobacco rod section 250 (these are collectively referred to as for the "Filter Section"). In FIG. 4 , the second filter section F2 is shown in the form of the filter section 100 of the present invention, but the first filter section F1 may be composed of the filter section 100 of the present invention. The tobacco rod 250 contains tobacco chips 260 (chip leaves, tobacco), and a wrapping paper 270 wrapped around it. The tobacco rod portion 250 , the first filter segment F1 and the second filter segment F2 are connected by the paper sheet member 280 . The sheet member 280 may have ventilation holes in a portion of its outer circumference. The number of ventilation holes may be one or plural, for example, 10 to 40 may be formed. When the number of the ventilation holes is plural, the ventilation holes may be arranged in a line on the outer peripheral portion of the sheet member 280 in a ring shape, for example. A plurality of ventilation holes may be arranged at approximately regular intervals. By providing the vent hole, air is taken in from the vent hole into the filter part during inhalation. The mainstream smoke is desalinated by the air from the vent hole, and the product design of the desired tar value can be carried out. When F2 is the filter section of the present invention, F1 is a common acetate filter in which cellulose acetate long fiber bundles are added with triacetin, which is a plasticizer, and then rolled into a cylindrical shape with a filter wrap. filter; after removing particulates from the filter of the present invention, it will contain fibers and The non-woven fabric sheet of the binder is rolled into a cylindrical shape with a filter wrapping body; or it can be a paper filter wrapping a filter wrapping body into a cylindrical shape by wrinkling and wrinkling the paper device.

In the burning tobacco flavor tasting article, the length of the F2 section may be about 10 to 15 mm. At this time, about 20 to 100 mg of granular material can be filled in the F2 stage. When using activated carbon as granular material, from the point of view of the aroma quality of the combustion-type tobacco flavor tasting article, it is better to fill about 20 to 50 mg in the F2 stage, so as to remove the volatile components in the mainstream smoke. From a viewpoint, it is preferable to fill about 50 to 100 mg in the F2 stage.

The user ignites the front end of the tobacco rod portion 250, holds the mouth end of the first filter section F1 in his mouth and inhales, thereby enjoying the aroma of the tobacco. By appropriate selection of the particles 13 in the filter segment 100, various functions can be imparted to the combustible tobacco flavoring article 240.

In addition, these volatile fragrance components may be used alone or in combination of two or more.

The content of the mist-generating base material in the tobacco filler 350 is not particularly limited, but from the viewpoint of sufficiently generating mist and imparting a good flavor, it is usually 5 to 50% by weight, preferably 10 to 50% by weight. 20% by weight. When the tobacco filler 350 contains volatile flavor components, the content of the volatile flavor components in the tobacco filler is not particularly limited. From the viewpoint of imparting a good flavor, it is usually 100 ppm or more relative to the weight of the tobacco filler, which is relatively low. It is preferably 10,000 ppm or more, more preferably 25,000 ppm or more, and usually 100,000 ppm or less, preferably 50,000 ppm or less, and more preferably 33,000 ppm or less.

The method of filling the tobacco filler 350 into the wrapping body 360 is not particularly limited, for example, the tobacco filler 350 can be wrapped with the wrapping body 360 , or the cylindrical wrapping body 360 can be filled with the tobacco filler 350 . When the shape of the tobacco has a longitudinal direction such as a rectangular shape, the tobacco system can be filled in such a way that the longitudinal direction is in an unspecified direction in the covering body 360, or it can be relative to the axial direction of the tobacco rod portion 310 or perpendicular to the axial direction. Fill in the way of the direction. By heating the tobacco rod 310, the tobacco components, the aerosol-generating substrate, and the water contained in the tobacco filler 350 are vaporized, which are moved toward the mouthpiece section 320 by smoking.

The cooling stage 330 is constituted by a cylindrical member 370 . The cylindrical member 370 may be, for example, a paper tube obtained by processing thick paper into a cylindrical shape. The cylindrical member 370 and the mouthpiece lining paper 420 described later are provided with a perforation 380 penetrating both. Due to the existence of the perforations 380, the outside air is introduced into the cooling section 330 during inhalation. Thereby, the vaporized component of the mist generated by the heating of the tobacco rod portion 310 contacts with the outside air, and the temperature is lowered to liquefy and form the mist. The diameter (diameter length) of the perforation 380 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 380 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 380 may be provided around the cooling section 330 .

The central hole section 340 is composed of a filling layer 390 having a hollow portion and an inner plug covering body 400 covering the filling layer 390 . The central hole section 340 has the function of increasing the strength of the mouthpiece section 320 . The filling layer 390 can be, for example, filled with high-density cellulose acetate fibers, with respect to the weight of cellulose acetate, adding 6 to 20% by weight of a plasticizer containing triacetin, and the hardened inner diameter is φ 5.0 to φ 1.0mm Of rod. The filling layer 390 has a high filling density of fibers, so when inhaled, air or mist flows only in the hollow part, and hardly flows in the filling layer 390 . To reduce the reduction of the mist components in the filter portion due to filtration, the length of the filter portion is shortened and replaced with the central hole section 340, which can effectively increase the transmission amount of the mist components. The filling layer 390 inside the central hole section 340 is a fiber filling layer, so the contact feeling from the outside during use is good.

The central hole section 340 is connected to the filter part by the outer plug covering body 410 . The outer plug cover 410 can be, for example, a cylindrical paper. In addition, the tobacco rod part 310 , the cooling section 330 , the connected central hole section 340 and the filter part are connected by the inner lining paper 420 of the mouthpiece. For these connections, for example, a paste such as vinyl acetate-based paste is applied to the inner side of the mouthpiece liner 420, and the above-mentioned three sections can be placed and rolled for connection.

The axial direction of the non-combustion heating tobacco flavor smoking article, that is, the length of the horizontal direction in FIG. 5 is not particularly limited, but preferably 40 to 90 mm, more preferably 50 to 75 mm, and 50 to 60 mm For better. In addition, the length of the periphery of the non-combustion heating tobacco flavor tasting article is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. For example, the length of the tobacco rod 310 is 20 mm, the length of the cooling section 330 is 20 mm, the length of the central hole section 340 is 6 mm, and the lengths of the first filter section F1 and the second filter section F2 are respectively 7.0mm form. The lengths of these respective segments can be appropriately changed in accordance with suitability for manufacturability, quality requirements, and the like. At this time, the weight of the particulate matter contained in the second filter stage F2 is 15 to 50 mg. Furthermore, the central hole section 340 may not be used, and only the filter portion may be disposed on the downstream side of the cooling section 330 . Various functions can be imparted to the combustible tobacco flavored tasting article 240 by appropriate selection of the particles 13 in the filter segment 100 .

(3) Non-combustion heating tobacco flavor tasting system

The non-combustion heated tobacco flavor tasting article is preferably used in combination with a device for heating the article. This combination is also known as a non-combustion heated tobacco flavor tasting system. A well-known device can be used, for example, it is preferable to have a heater using a resistance.
