Description

Smoking items

The present invention relates to a smoking article which provides aroma in both suction at a normal temperature (non-heated smoking) and smoking after a fire (heated smoking).

The conventional paper-rolled tobacco enjoys aroma by burning tobacco filaments and generating components such as smoke and tar. However, in the past, paper-rolled tobacco hardly felt aroma when it was not heated.

On the other hand, it is known that non-heated smoking articles which taste the tobacco flavor only by inhalation without igniting the fire. For example, in Patent Document 1, a tobacco granule containing tobacco filaments, carbonates, and flavors is used as a filler, and the swelling feeling of the flavor component is produced by the action of the carbonate, and the suction feeling of the air containing the flavor component is enhanced. The related non-heating type smoking articles are those which taste the flavor component at normal temperature, and do not have a structure such as smoking after heating.

On the other hand, a non-combustion type smoking article in which a combustion heat source is used and the tobacco filament or the sheet tobacco is heated without burning by the heat to produce an aerosol containing a flavor component is known (for example, refer to Patent Document 2). . Related non-combustible smoking articles can be tasted by heating the tobacco filaments or flake tobacco exposed to high temperatures, but the fragrance is hardly felt when not heated.

The invention is described below with reference to the drawings, but the following description is intended to be illustrative of the invention.

The smoking article of the present invention is a cylindrical smoking article comprising: a burning portion at a front end; a first flavor generating portion located at a rear end of the burning portion, comprising a tobacco material containing a low vapor pressure flavor component; and a second flavor generating portion a tobacco material containing a high vapor pressure flavor component at the rear end of the first flavor generating portion, and a non-combustible cylindrical body for packaging the first flavor generating portion and the second flavor generating portion, at least a front end of the burning portion Some are not packaged and suddenly Out.

In the smoking article of the present invention, the burning portion may be made of the same material as the first flavor generating portion, whereby the burning portion and the first flavor generating portion are integrated. Alternatively, the combustion portion may be provided with a carbonaceous heat source and physically separated from the first flavor generating portion.

The former is referred to as "the first aspect" and "integrated type", and the latter is referred to as the "second aspect" and the "separate type". An example of the integrated type is shown in Fig. 1 and an example of a separate type is shown in Fig. 2.

The smoking article 10 shown in Fig. 1 includes a burning portion 12a located at the front end, and a first flavor generating portion 12b located at the rear end of the burning portion 12a and integrated with the burning portion 12a. The second flavor generating portion 13b is provided at the first portion. The rear end of the flavor generating portion 12b; the non-combustible cylindrical body 14 is provided with the first flavor generating portion 12b and the second flavor generating portion 13b, and the burning portion 12a is unpacked and protruded; and the filter portion 15 is provided in the second flavor generating portion. The rear end of 13b; and the chip paper 16 are connected to the cylindrical body 14 and the filter portion 15.

In the first drawing, the combustion portion 12a and the first flavor generating portion 12b are formed of the same material, and are collectively referred to as a combustion-type first flavor generating portion 12. In the first type flavor generating portion 12, the portion to be packaged by the incombustible cylindrical body 14 is the first flavor generating portion 12b, and is not packaged by the incombustible cylindrical body 14 and protrudes from the front end of the incombustible cylindrical body 14. The protruding portion is the burning portion 12a. When the smoking article of Fig. 1 is ignited at the front end of the burning portion 12a and is sucked by the smoker to burn the burning portion 12a, the combustion stops when reaching the front end of the incombustible cylindrical body 14, and the burning portion 12a continues to be smoked. combustion, However, the first flavor generating portion 12b hardly burns.

On the other hand, the smoking article 10 shown in Fig. 2 includes a burning portion 11 at the front end, a first flavor generating portion 12b provided at the rear end of the burning portion 11, and a second flavor generating portion 13b provided at the first flavor generating portion. The rear end of the portion 12b; the non-combustible cylindrical body 14 is provided with the first flavor generating portion 12b and the second flavor generating portion 13b, and the end portion of the combusting portion 11 is connected to the combustion portion 11, and the filter portion 15 is provided. The non-combustible cylindrical body 14 and the filter portion 15 are connected to the rear end of the second flavor generating portion 13b and the outer layer paper 16.

In Fig. 2, the combustion portion 11 contains a carbonaceous heat source and is provided physically separated from the first flavor generating portion. Therefore, in the second embodiment, the incombustible cylindrical body 14 is not only packaged with the first flavor generating portion 12b and the second flavor generating portion 13b, but also the end portion of the burning portion 11 is connected to the combustion portion 11. The incombustible cylindrical body 14 does not cover all the combustion portions 11, and the combustion portion 11 must have a protruding portion that is not covered by the incombustible cylindrical body 14 and protrudes from the front end of the incombustible cylindrical body 14. This projection is indicated by the symbol 11a in FIG. In the smoking article of Fig. 2, when the front end of the burning portion 11 is ignited and the combustion portion 11 is burned by the smoker, the combustion will reach the front end of the incombustible cylinder 14 (i.e., after reaching the rear end of the protruding portion 11a). When it is stopped, the burning portion 11 continues to burn in a smoked manner, but the first flavor generating portion 12b hardly burns.

The constituent elements of the smoking article of the present invention are explained below. Unless otherwise specified, the following description is a description of the above two aspects.

The combustion section generates a heat portion by burning on fire. First aspect In the middle, the combustion portion is composed of the same material as the first flavor generating portion, that is, a tobacco filament to which a low vapor pressure flavor component is added and/or a tobacco molded article to which a low vapor pressure flavor component is added. In the first aspect, in order to improve the ignitability, the material of the burning portion and the first flavor generating portion may contain carbon. On the other hand, in the second aspect, the combustion portion contains a carbonaceous heat source and is provided physically separated from the first flavor generating portion. "Physical separation" means consisting of physically different materials. The carbonaceous heat source in the second aspect may use a carbonaceous heat source generally used for non-combustible smoking articles. The carbonaceous heat source is composed, for example, of carbon (particles or fibers) and a binder for bonding with carbon, and if it is ignited, it burns and generates heat (refer to WO2009/084458). In the second aspect, the combustion portion may be composed of a carbonaceous heat source and a cylindrical paper sheet (not shown in Fig. 2) which is wrapped around the carbonaceous heat source without peeling off the carbonaceous heat source.

The first flavor generating portion 12b includes a tobacco material containing a low vapor pressure flavor component, for example, a tobacco filament containing a low vapor pressure flavor component or a tobacco molded article containing a low vapor pressure flavor component.

In the present specification, the "low vapor pressure flavor component" is a component having a vapor pressure of less than 0.1 mmHg at 20 °C. That is, the low vapor pressure flavor component is a component which is hard to volatilize at normal temperature (for example, 20 to 25 ° C) but is easily volatilized at a high temperature (for example, 100 ° C or higher). The low vapor pressure flavor component has almost no function as a flavor component at normal temperature, and the function of being a flavor component is exhibited when exposed to a high temperature. Examples of the low vapor pressure flavor component include nicotine (vapor pressure 0.0045 mmHg), vanillin (vapor pressure 0.01 mmHg), sorbitol (vapor pressure less than 0.1 mmHg), or a mixture of any of these.

In the present specification, the reference to the vapor pressure means the vapor pressure at 20 °C. The vapor pressure is a value measured by a stationary method, a boiling point method, or the like. For the sake of simplicity, the vapor pressure can be referred to the values stated in the MSDS Product Safety Data Sheet.

The second flavor generating portion 13b includes a tobacco material containing a high vapor pressure flavor component, and may be composed of, for example, a tobacco filament containing a high vapor pressure flavor component or a tobacco molded article containing a high vapor pressure flavor component.

In the present specification, the "high vapor pressure flavor component" is a component having a vapor pressure of 0.1 mmHg or more at 20 °C. That is, the high vapor pressure flavor component is a component which is easily volatilized at normal temperature (for example, 20 to 25 ° C). The high vapor pressure flavor component will volatilize at normal temperature and high temperature, but at high temperature, the volatile content of the low vapor pressure flavor component will increase, so the high vapor pressure flavor component mainly functions as a flavor component at normal temperature. Examples of the high vapor pressure flavor component include menthol (vapor pressure 0.8 mmHg), limonene (vapor pressure 1.425 mmHg), linalool (vapor pressure 0.17 mmHg), menthone (0.5 mmHg), 2,5-dimethylpyridine. (12mmHg), 2,6-dimethylpyrazine (12mmHg) or any such mixture.

The first flavor generating unit 12b and the second flavor generating unit 13b (collectively referred to as the flavor generating unit) each include a material containing a flavor component, for example, a tobacco filament containing a flavor component or a tobacco component containing a flavor component. The composition of the product. Here, the "tobacco material" means a tobacco material generally used for smoking articles, such as tobacco filaments, tobacco leaf chips, tobacco filaments, and petiole, which may be arbitrarily combined. In addition, "containing a flavor component" herein means two cases in which a tobacco material for modulating a tobacco filament or a tobacco molded article contains a flavor component in advance, so that when a tobacco filament or a tobacco molded article is prepared, There is no case where a flavor component is added to the raw material mixture; or a flavor component is added to the raw material mixture when the tobacco filament or the tobacco molded article is prepared. Regarding "tobacco raw materials containing a low vapor pressure flavor component", since the tobacco raw material contains nicotine in advance, the additional low vapor pressure flavor component may be added to the tobacco material or may not be added, but it is preferred to add nicotine to the tobacco material. Low vapor pressure flavor component. On the other hand, "tobacco material containing a high vapor pressure flavor component" preferably has an additional high vapor pressure flavor component added to the tobacco material.

For example, the first flavor generating portion may be a tobacco filament used in a normal cigarette, or may be a tobacco filament having a tobacco rod shape, and the second flavor generating portion may be a tobacco filament used in an unheated smoking article. It can also be a tobacco filament having a tobacco rod shape.

Alternatively, the tobacco-formed product may be prepared by folding a tobacco molded article of a sheet structure (hereinafter referred to as "sheet tobacco") in a folded manner. The thickness of the sheet tobacco may be, for example, 0.01 to 2 mm.

An example of a cross section of the flavor generating portion composed of the folded sheet tobacco in the vertical direction in the longitudinal direction is shown in Fig. 3. In Fig. 3, one sheet of tobacco 121 is folded in a non-combustible cylindrical body 14 having a substantially cylindrical outer shape to form a first flavor generating portion 12b or a second flavor generating portion 13b (12b/13b). The voids of the unfilled sheet tobacco 121 form a single or plural air flow path 122. By changing the number of associated air flow paths or the width of the flow path, the overall attraction resistance of the smoking article can be adjusted. The sheet tobacco can be folded in any shape within the incombustible cylindrical body 14.

Alternatively, the flavor generating portion may be a cylindrical honeycomb shaped tobacco product ( This is called "honeycomb structure tobacco".

An example of a cross section of a flavor generating portion composed of honeycomb structure tobacco in a direction perpendicular to the longitudinal direction is shown in Fig. 4 . In Fig. 4, the honeycomb structure tobacco 123 is filled in the incombustible cylindrical body 14 to form the first flavor generating portion 12b or the second flavor generating portion 13b (12b/13b). The plurality of through holes in the honeycomb structure tobacco 123 form an air flow path 122. In Fig. 4, the air flow path 122 has a hexagonal cross-sectional shape, but may have a circular shape or a quadrangular shape.

The flavor generating portion is not limited to the folded sheet shape and the cylindrical honeycomb shape, and may have any shape as long as it can form an air flow path when filled in the incombustible cylindrical body. For example, a tobacco molded article having a cylindrical body having one or more through holes of any cross-sectional shape (star or letter shape) or a porous tobacco molded article can be used.

If necessary, the tobacco filament or the tobacco molded article can be packaged into a cylindrical shape by a roll paper, and filled in the incombustible cylindrical body 14 to prepare a flavor generating portion, and the tobacco filament or the tobacco molded article can also be directly used. The inflammable cylindrical body 14 is filled to prepare a flavor generating portion.

The non-combustible cylindrical body 14 is provided with the entire first flavor generating portion 12b and the second flavor generating portion 13b. However, at least the front end portion of the burning portion (12a in the first drawing and 11 in the second drawing) is not packaged and protrudes. "At least the front end portion of the burning portion is not packaged and protruded" means the following two cases: the case where the entire combustion portion is unpackaged and protruded, and the case where only the front end portion of the burning portion is unpackaged and protruded. In other words, the protruding portion corresponds to the entire combustion portion 12a of Fig. 1 and corresponds to the front end portion (i.e., the protruding portion 11a) of the burning portion 11 of Fig. 2.

Further, the incombustible cylindrical body 14 has thermal conductivity and gas barrier properties. That is, the incombustible cylindrical body 14 has a non-combustibility to the extent that the combustion portion can be stopped for combustion, and has a degree of thermal conductivity that can transmit heat generated by combustion of the combustion portion, and has a degree of blocking such that the fragrance component does not volatilize. Gas barrier properties.

When the incombustible cylindrical body 14 is incombustible, the combustion of the combustion portion can be stopped when the combustion of the combustion portion reaches the tip end of the incombustible cylindrical body 14. Further, the incombustible cylindrical body 14 has thermal conductivity, whereby the heat generated by the combustion of the combustion portion is efficiently transmitted to the first fragrance generating portion 12b located at the lower end thereof, and the release efficiency of the low vapor pressure flavor component can be improved. Further, the incombustible cylindrical body 14 has gas barrier properties, whereby the flavor component, that is, the high vapor pressure flavor component is volatilized at normal temperature.

Specifically, the incombustible cylindrical body 14 has the property of not sustaining combustion, and the thermal conductivity is 15 W/m. K or more, and oxygen transmission rate (measurement conditions of 23 ° C - 80% RH ISO15105-2) is less than 1000 [cm3 / m2 / day / atm] of materials, or contain related materials. For example, stainless steel, aluminum, glass, flame retardant coating materials (矽, etc.), ethylene-vinyl alcohol copolymer resin (EVOH), MXD6 resin, polyethylene terephthalate (PET), PA6 resin, poly bias Made up of materials such as dichloroethylene (PVDC) or containing any such materials.

More specifically, it can be made of a non-combustible material having thermal conductivity and gas barrier properties, a paper sheet containing a non-combustible material having thermal conductivity and gas barrier properties, or a non-combustible material having thermal conductivity and gas barrier properties. The lined paper sheet forms a non-combustible cylindrical body 14. For example, aluminum can be used, A metal foil-lined paper sheet such as stainless steel, a thermally conductive resin or ceramic, or a paper sheet containing glass fibers. A non-combustible cylindrical body made of a metal foil (a thickness of 5 to 100 μm) such as aluminum or stainless steel can be referred to WO2011/118023.

As shown in FIGS. 1 and 2, the incombustible cylindrical body 14 may have an opening OP formed above the second flavor generating portion 13b, and preferably an opening OP is formed upstream of a region where the second flavor generating portion 13b is packaged. When the non-combustible cylindrical body 14 has the opening OP above the second flavor generating portion 13b, air can be taken in by the opening OP in addition to the air taken in from the tip end of the burning portion, and the flavor acceptability can be improved when sucked at a normal temperature. Further, when the incombustible cylindrical body 14 is provided with the opening OP, the ventilation resistance can be lowered. The opening OP may be provided only at one of the incombustible cylindrical bodies 14, or may be provided in a large number in a row, a plurality of columns or an irregular manner along the circumferential direction of the smoking article.

The filter unit 15 can use a medium pore filter, an acetate filter, a paper filter, or a sputum filter. The mesoporous filter has a hollow portion penetrating the central portion of the filter. The acetate filter has a configuration in which a cellulose acetate fiber filament is wrapped by a roll paper. The paper filter has a structure in which fine wrinkles are attached to the paper-like sheet paper, and the one side is twisted and rolled up. The break-in type filter has a filter plug which is rolled up by a roll paper, and the mouthpiece has a recessed configuration.

The mesoporous filter is superior in that it is easy to attract a high vapor pressure flavor component through the hollow portion. The paper filter is excellent in that it attracts the smoke at the normal temperature or when the smoking article is stored, and the fragrance is inhibited from adhering to the filter.

The outer layer paper 16 is a layer paper which is usually used for cigarettes, and connects the cylindrical body 14 and the filter portion 15. In the first and second figures, the filter portion 15 is connected to the rear end of the second flavor generating portion 13b by using the outer layer paper 16, but the incombustible cylindrical body 14 can be further extended on the filter side and transmitted through the elongated portion. The second flavor generating portion 13b and the filter portion 15 are connected.

The smoking article of the present invention has a cylindrical shape as a whole and can have the appearance of a usual cigarette. The cross section perpendicular to the longitudinal direction of the smoking article does not necessarily need to be a perfect circle, and there may be some distortion or recess in the range that does not hinder smoking.

For example, the smoking article can have a total length of 50 to 180 mm and a diameter of 4 to 12 mm. In the first aspect, the burning portion 12a may have a length of 5 to 40 mm, and in the second aspect, the burning portion 11 may have a length of 10 to 40 mm, and the protruding portion 11a may be slightly shorter than the burning portion 11, and may have a length of 5 to 35 mm. When the burning portion is too short, the number of times of suction is reduced, and if the burning portion is too long, heat generated by combustion is hardly transmitted to the thermally conductive material of the incombustible cylindrical body. The first flavor generating portion 12b may have a length of 20 to 50 mm, and the second flavor generating portion 13b may have a length of 20 to 50 mm. The lengths of the first flavor generating portion 12b and the second flavor generating portion 13b may be the same or different. In the first aspect, the incombustible cylindrical body 14 is (the length of the first flavor generating portion 12b) + (the length of the second flavor generating portion 13b), and may have a length of 25 to 95 mm, and in the second aspect, (The length of the burning portion 11) + (the length of the first flavor generating portion 12b) + (the length of the second flavor generating portion 13b) - (the length of the protruding portion 11a) may have a length of 45 to 135 mm. The filter portion 15 has a length of 5 to 40 mm. If the filter part is too short, it is difficult to smoke. If it is too long, the component filtration will be excessive.

In addition, in this specification, "length" means the dimension of the longitudinal direction of a smoking article.

According to the present invention, the high vapor pressure flavor component is disposed adjacent to the suction port of the smoking article (i.e., on the downstream side) in a state of being separated from the low vapor pressure flavor component, whereby the suction at normal temperature (non-heated smoking) is clear. A strong intensity of aroma derived from a high vapor pressure aroma component is felt. On the other hand, the low vapor pressure component is disposed adjacent to the combustion portion of the smoking article (that is, on the upstream side) in a state of being separated from the high vapor pressure flavor component, whereby the smoking can be felt in the same manner as a normal burning cigarette. To the aroma derived from low vapor pressure aroma components. Thus, according to the smoking article of the present invention, the high vapor pressure flavor component and the low vapor pressure flavor component are separated and arranged in a specific order, whereby the flavor can be changed between the non-heated smoking and the heated smoking, and the taste can be clearly tasted separately. The scent of the species. Further, the flavor generating portion containing the high vapor pressure flavor component is disposed on the downstream side, whereby the advantage of volatilization of the volatile component at normal temperature can be suppressed.

Figure 5 is a schematic representation of the change in aroma between non-heated smoking and heated smoking. Fig. 5 is a graph showing the proportion of the low-vapor pressure aroma component in the inhalation as a whole in the flavor component, and the proportion of the high vapor pressure flavor component in the inhalation as a whole in the flavor component. As shown in Fig. 5, the high vapor pressure flavor component will be volatilized during non-heating smoking, and the low vapor pressure flavor component will hardly be volatilized, so that the high vapor pressure flavor component of the flavor component accounts for the majority. After the fire, the amount of volatilization of the low vapor pressure flavor component is increased, and on the other hand, the amount of volatilization of the high vapor pressure flavor component hardly changes, so that the proportion of the low vapor pressure flavor component in the whole flavor component is increased. Heated smoking In the middle, the volatilization of the low vapor pressure flavor component is much higher than the volatilization amount of the high vapor pressure flavor component, so the proportion of the high vapor pressure flavor component is significantly reduced.

Thus, after smoking a high vapor pressure flavor component by non-heating smoking, the smoking article of the present invention can taste a low vapor pressure flavor component by heating the cigarette.

Hereinafter, a method for producing a sheet tobacco and a method for producing a honeycomb structure tobacco will be described in more detail.

The flaked tobacco can be produced according to a conventional method, and can be produced, for example, by mixing a polyol, a tobacco fine powder, a flavor component, an organic binder, and water, casting it in a mold, and drying it.

The thickness of the sheet can be from 0.5 to 2.0 mm, preferably from 0.5 to 1.5 mm, when cast. When the thickness of the sheet is thinner than the above lower limit value, cracking is likely to occur during drying, and if it is thicker than the above upper limit value, the drying time is increased.

As the polyol, glycerin or polyglycerin can be used. When the polyol is included in the raw material together with the high vapor pressure flavor component, the main function of the polyol is a moisturizer and a forming agent. When the polyol is included in the raw material together with the low vapor pressure flavor component, the polyol functions as a moisturizer. A forming agent and an aerosol generating agent.

The tobacco fine powder can be used as the raw material quality standard for the sheet tobacco, which is used for the leaf scraps and filaments produced by the manufacturing steps of the tobacco filament. When the tobacco fine powder is contained in the raw material together with the high vapor pressure flavor component, pulp, cotton, vanilla (Hyssopus officinalis, Lemon balm, mint, nine-story tower, Oregano, etc.) can be used. Marjoram, Shiso, egoma, Rosemary, Sage, Satureja, Thymus, fennel Solids such as Anise, Angelica, Chervil, Coriander, Chamomile, Wormwood, Lavender are substituted for tobacco fines.

As the flavor component, nicotine may be added to the first flavor generating portion, or nicotine and other additional low vapor pressure flavor components may be added, or the tobacco powder may contain nicotine without adding any component. Further, menthol may be added to the second flavor generating portion, or menthol and other additional high vapor pressure flavor components may be added.

The function of the organic binder is a forming agent, and for example, carboxymethylcellulose, sodium carboxymethylcellulose, methylcellulose, hydroxypropylcellulose, hydroxyethylcellulose, ammonium alginate, sodium alginate can be used. Calcium alginate, calcium alginate, potassium alginate, magnesium alginate, triethylamine alginate, propylene glycol alginate, ammonium alginate, copper alginate, zinc alginate, silver alginate, gum arabic, Glycine (Ghatti gum), tragacanth gum, karaya gum, Ceratonia siliqua gum, acacia gum, guar gum, glutinous gum (Cydonia oblonga seed gum), xanthan gum, locust bean gum, gellan gum, tamarind gum, Caesalpinia spinosa gum, Psyllium seed gum, Konjac glucomannan, starch, cold weather, agarose, carrageenan, Fucus or furcellaran.

Honeycomb structure tobacco can also be made according to conventional methods, using the above thin The same raw material of the piece of tobacco can be produced by extruding the mixture through a mold and drying.

In the case of the first flavor generating portion, the raw material composition (excluding water) of the tobacco molded article such as flake tobacco or honeycomb structure tobacco may be:

(a) 11 to 27% by mass of polyol

(b) 14 to 69% by mass of tobacco filaments

(c) 0 to 41% by mass of low vapor pressure flavor component

(d) 3 to 18% by mass of an organic binder.

Here, since the tobacco filament contains nicotine, the added low vapor pressure flavor component may or may not be added.

Further, in the case of the second flavor generating unit, it may be:

(a) 11 to 27% by mass of polyol

(b) 12 to 66% by mass of tobacco filaments

(c) 5 to 47% by mass of high vapor pressure flavor component

(d) 3 to 18% by mass of the organic binder

In the case of flake tobacco, the amount of water can be suitably cast, for example, from 70 to 80% of the total mass of the raw material. Further, in the case of honeycomb construction of tobacco, the amount of water may be an appropriate amount for extrusion molding, for example, 10 to 40% of the total mass of the raw material.

When the ratio of the polyol is less than the above lower limit, the tobacco molded article becomes brittle, and if the ratio is higher than the above upper limit, the moisture of the molded article becomes excessive. . Further, when the proportion of the fine powder of tobacco is less than the above lower limit, the drying time is increased, and if it exceeds the above upper limit, a solid content is likely to be formed during molding. The case of the first fragrance generating unit, if When the ratio of the tobacco filaments is less than 14% by mass, a sufficient fragrance cannot be obtained. Further, if the proportion of the flavor component is less than the above lower limit, sufficient flavor cannot be obtained, and if it is higher than the above upper limit, it may become a less favorable flavor or may become difficult to dissolve. Further, if the ratio of the organic binder is less than the above lower limit, it is difficult to form, and if it is higher than the above upper limit, the drying time is increased.
