Description

Non-combustion heated cigarettes, electrically heated cigarettes and non-combustion heated tobacco materials

The present invention relates to a non-combustion heated cigarette, an electrically heated cigarette product, and a non-combustion heated tobacco material.

Common cigarettes (paper-rolled cigarettes) are made by connecting tobacco rods and mouthpiece rods with end-to-end lining paper. Tobacco dried leaves that are cut into a width of about 1mm and rolled into a cylindrical shape, and the nozzle rod is a paper roll made of fibers or wrinkled fibers made of cellulose acetate. The pleated paper rolls are packed in a cylindrical shape.

Usually, when using a cigarette, the user ignites the tobacco rod at the end of the tobacco rod with a lighter, etc., and smokes from the end of the mouthpiece to smoke. The fire at the front end of the tobacco rod burns at a temperature of over 800°C.

As a substitute for such a common cigarette, a non-combustion heating type flavoring article and a non-combustion heating type tobacco flavoring system using electric heating without combustion have been developed (Patent Documents 1 to 7).

A general non-combustion heated tobacco flavor smoking system (non-combustion heated cigarette product) consists of a cylindrical non-combustion heated tobacco flavor smoking article similar to a normal cigarette, and a battery, a controller, a heater, etc. Consists of a heating device. The heaters are those that utilize resistance and those that utilize IH. Regarding the heater utilizing resistance, the contact point between the heater and the non-combustion heating tobacco flavor tasting article is: It is configured to smoke from the cylindrical non-combustion heating tobacco flavor. Those in which the outer side of the article is heated, or those in the form of needles and sheets are inserted into the tobacco filling layer from the front end of the non-combustion heating tobacco flavor tasting article.

The heating temperature varies, but many are heated at a lower temperature (200 to 400°C) than the combustion type of 800°C. In order to ensure user satisfaction even when heated at a low temperature, that is, the appearance quality, or taste and aroma of mainstream smoke produced from tobacco flavored smoking articles are similar to cigarettes, Contains glycerin, PG, triacetin and other mist (aerosol, also known as aerosol) generating substrates, in addition to the volatile aroma components contained in tobacco and additional flavor components, you can also taste The volatilized mist forms the substrate. The mist-generating base material is temporarily volatilized by heating with a heater, and when it is sucked and moved to the mouthpiece, it is cooled and liquefied to become mist, and becomes a white smoke whose appearance is similar to that of a cigarette itself.

The non-combustion heating cigarette generally includes a tobacco material composed of a composition including shredded tobacco, a mist-generating base material, and the like. When the aforementioned heated cigarette product is used, the aforementioned non-combustion heated cigarette is inserted or placed in the aforementioned heated apparatus. Next, the aforementioned heating The set heat source generates heat and utilizes its heat to heat the tobacco material in the non-combustion heated cigarette, whereby the mist and flavor components are delivered to the user.

In general non-combustion heating cigarettes, as described above, an aerosol-generating substrate is used. In use of the above article, a volatile compound is released from the heated mist-generating substrate, which is condensed to form a mist by subsequent cooling of the volatile compound. At this time, the particle size of the condensed mist is relatively large, so it is generated in the state of visible white tobacco vapor. The visible tobacco vapor can sometimes cause unpleasantness to third parties around the user.

In Patent Document 8, the heating temperature of the non-combustion heating cigarette is lowered from 150 to 220° C. to 80 to 140° C. to reduce the amount of volatilization, and to achieve visible suppression of tobacco vapor.

<Tobacco material>

The tobacco material in the first non-combustion heating cigarette described above is referred to as "first tobacco material", and the tobacco material in the second non-combustion heating cigarette is referred to as "second tobacco material".

In addition, according to another embodiment of the present invention, the total amount of glycerin, propylene glycol, triacetin, and 1,3-butanediol added to 100% by weight of the tobacco material for non-combustion heating cigarettes is The tobacco material for non-combustion heating cigarettes in which the tobacco material is 10% by weight or less and the tobacco material is granular is called "third tobacco material".

In addition, in this specification, the so-called "granular form" of the tobacco material means that the tobacco material in the above-mentioned embodiment does not contain sheet-like tobacco material.

[Mist generation substrate]

The first tobacco material and the third tobacco material are not particularly limited as long as the addition amount of the aerosol-generating base material is 10% by weight or less with respect to 100% by weight of the tobacco material. For example, one composed of a composition containing shredded tobacco or pulverized tobacco can be used. by misting the tobacco material When the content of the generation base material is within the above-mentioned range, the generation of mist and the generation of visible tobacco vapor can be suppressed.

The so-called mist-generating substrate in the present invention means glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof. Only the above-mentioned types are used as the mist-generating substrates used in general non-combustion heating cigarettes. Therefore, the effect of the present invention can be obtained by controlling the addition amount of the above-mentioned types of substances to a certain value or less.

With respect to 100% by weight of the tobacco material, the addition amount of the aerosol-generating base material (the total addition amount of glycerin, propylene glycol, triacetin, and 1,3-butanediol) is not particularly limited as long as it is 10% by weight or less. From the viewpoint of achieving recognizable suppression of tobacco vapor, it is preferably 8 wt % or less, more preferably 5 wt % or less, still more preferably 3 wt % or less, particularly preferably 1 wt % or less, and most preferably 0 wt% (no added mist-generating substrate). In this specification, 0% by weight means below the detection limit.

Generally speaking, the aerosol-generating substrate is not just an additive produced by deliberately adding additionally, but also slightly contains raw materials of the tobacco material other than the aerosol-generating substrate, especially dried tobacco leaves, so that the aerosol-generating substrate in the tobacco material is It is practically impossible to completely set the content of 0 wt %. Generally, the content of the aerosol-generating base material in the tobacco material is 1 wt % or less without intentional external addition of the mist-generating base material. Specifically, usually, glycerin in dried tobacco leaves is 0.016 to 0.125% by weight, propylene glycol and 1,3-butanediol are in trace amounts, and triacetin is usually not contained, and even if they are all added up, it is 1 weight %the following. That is, the content of the mist-generating base material in the tobacco material is the amount of the mist-generating base material contained in the raw material of the tobacco material other than the mist-generating base material, especially the amount of the mist-generating base material contained in the dried tobacco leaves. The amount of mist generating substrate.

The addition amount of the mist-generating base material of the second tobacco material (the total addition amount of glycerin, propylene glycol, triacetin, and 1,3-butanediol) is not particularly limited, but it is necessary to achieve visible suppression of tobacco vapor. From the viewpoint of 100 wt % of the tobacco material, it is usually 10 wt % or less, preferably 8 wt % or less, more preferably 5 wt % or less, still more preferably 3 wt % or less, and particularly preferably 1 wt % % or less, preferably 0% by weight (no mist-generating base material added). Also, like the first tobacco material described above, the content of the mist-generating base material in the tobacco material is a factor of the raw material of the tobacco material other than the mist-generating base material, especially the mist-generating base material contained in the dried tobacco leaves. In the amount, the amount of the deliberately added mist-generating substrate is added.

Except for the above-mentioned factors of addition amount and content, the characteristics of the aerosol-generating substrate contained in the tobacco material in the second non-combustion heating cigarette can be applied to the above-mentioned first and third non-combustion heating cigarettes in the same way. Characteristics of aerosol-generating substrates contained in tobacco materials.

[form]

The form of the tobacco material is not particularly limited as long as it is in the form of granules. Preferred examples include (1) tobacco particles (also referred to as "tobacco material (A)"), (2) tobacco shreds or tobacco pulverized material. The one composed of the composition (also called "tobacco material (B)") is preferably the tobacco material (A) (granular).

In order to achieve the desired tobacco flavor, it is necessary to prepare various kinds of tobacco leaves and arrange them in the space of the non-combustion heating cigarette. Regarding the tobacco material (B), when the tobacco material is inserted into the space at a high speed, it is easy to produce variation in the mixing ratio ( i.e. uneven). On the other hand, since the tobacco material (A) is prepared by blending tobacco leaves at a predetermined blending ratio to produce pellets, when the tobacco material (A) is inserted into the space of the non-combustion heating cigarette at a high speed, the blending ratio is less likely to vary. In addition, since the tobacco material (A) is less broken during transportation of the tobacco material, the variation in ventilation resistance is less when the tobacco material (A) is used. For these reasons, tobacco material (A) is preferred to tobacco material (B).

Tobacco material may consist of only tobacco material (A) or tobacco material (B), but may also be a mixture of these, and may be a mixture containing other granular tobacco materials, but from the same as above. From a viewpoint, what consists only of the tobacco material (A) is preferable. When it is a mixture, the mixing ratio can be arbitrarily designed.

In addition, the so-called tobacco pellets in this specification means pelletized tobacco.

The ratio of the volume of the tobacco material to the total volume of the space is not particularly limited, and can be appropriately set according to the form of the non-combustion heating cigarette or the tobacco material, but is usually 25% by volume from the viewpoint of ensuring adequate ventilation resistance. Above, preferably 30% by volume or more, more preferably 40% by volume or more, still more preferably 50% by volume or more. By being 30% by volume or more, the flavor components contained in the tobacco material are sufficiently released to the user. Moreover, it is usually 75 volume % or less, Preferably it is 70 volume % or less, More preferably, it is 65 volume % or less, More preferably, it is 60 volume % or less. By being 70 vol% or less, the ventilation resistance does not become too large, a good suction feeling can be ensured, and the fluidity in the above-mentioned space of the tobacco material can be ensured.

The ratio of the weight of the tobacco material to the total volume of the space is not particularly limited, and can be appropriately set according to the form of the non-combustion heating cigarette or the tobacco material, but is usually 0.1 g/g from the viewpoint of ensuring suitable ventilation resistance. cm ³ or more, more preferably 0.3 g/cm ³ or more, and usually 1.5 g/cm ³ or less, preferably 1.0 g/cm ³ or less, more preferably 0.6 g/cm ³ or less.

The granulated tobacco material used in this embodiment is preferably graded through a sieve having the following meshes. For example, the ease of movement in the space portion or the high specific surface area is easily achieved, and even from the viewpoint of easily obtaining the easy control of the ventilation resistance or the excellent fragrance effect, in general, it is preferable not to pass through a sieve having a mesh of 149 μm (>149μm (above 149μm)), and those who pass through a sieve with a mesh of 1680μm (<1680μm (less than 1680μm)). Even The best ones do not pass through a sieve with a mesh of 250 μm (>250 μm (above 250 μm)), but pass through a sieve with a mesh of 840 μm (<840 μm (less than 840 μm)).

The average particle size of the granular tobacco material in this specification can be obtained by classifying the weight of the tobacco material obtained by grading with meshes of 850 μm, 710 μm, 600 μm, 500 μm, 425 μm, 300 μm, 212 μm, and 106 μm. This measurement can be performed using a sieve shaker (eg, AS 200 CONTROL manufactured by RETSCH).

The average particle size of the granulated tobacco material can be adjusted by classifying the tobacco material used. In addition, the measurement object of the above-mentioned average particle size only needs to be the particles after granulation, and it may be the particles to which the fragrance material or the mist generation base material is added, or the particles without the addition of the fragrance material or the mist generation base material. From the standpoint of determining a more precise average particle size, it is preferred to measure particles without added fragrances or mist-generating substrates. The size of the particles is presumed to vary little depending on the addition of fragrance or mist-generating substrates.

The average particle size of the granular tobacco material according to the embodiment of the present invention is preferably 400 μm or more and 700 μm or less.

In addition, the tobacco material may have a fitting portion with a heater member or the like for heating the non-combustion heating cigarette.

[Scent development aid]

In the tobacco material, flavor development aids may be added. The flavor development adjuvant contains at least one of alkali metal and/or alkaline earth metal carbonate, bicarbonate, oxide and hydroxide. The flavor development aid is preferably potassium carbonate or sodium carbonate. By adding flavor development aids, the volatilization of tobacco content components mostly amines is ensured, and sufficient tobacco flavor can be displayed even in non-combustion heating cigarettes of a type heated at a relatively low temperature.

The pH of the tobacco material can be adjusted to 6.5 to 11.0 by adding flavor development aids.

The pH in this specification is measured by a pH meter (for example, IQ240 manufactured by IQ Scientific Instruments Inc.), for example, adding 10 times the amount of distilled water by weight to 2 to 10 g of the tobacco material, and mixing the water with the water at 22°C. The mixture of tobacco material was shaken at 200 rpm for 10 minutes, and after standing for 5 minutes, the pH of the resulting extract was measured with a pH meter.

The pH of the tobacco material at the measurement temperature of 22°C is not particularly limited, but it is usually 6.5 or more, preferably 7.0 or more, from the viewpoint of ensuring volatilization of tobacco content components such as nicotinic acid and mostly amines , more preferably 7.5 or more, and usually 11.0 or less, preferably 10.0 or less. In addition, the pH is easily determined mainly by the type and amount of the above-mentioned flavor development aids, but may be changed for other materials.

Although the pH of the tobacco material used in general cigarettes or non-combustion heating cigarettes varies depending on the type of tobacco used or the type of flavoring ingredients added, it is 4 depending on the contribution of various organic acids contained in it. To about 6, but in the case of such a small pH, that is, in the case of an acidic environment, most of the tobacco content components belonging to amines are difficult to volatilize. In this regard, in general cigarettes and non-combustion heating cigarettes, since the heating temperature at the time of use is high, the desired volatilization amount of many tobacco content components belonging to amines is ensured. However, when the heating temperature during use is high, not only does the mist-generating substrate volatilize, but other components are also decomposed, resulting in easy generation of white tobacco vapor.

On the other hand, by setting the pH of the tobacco material to the above-mentioned range, the heating temperature at the time of use can be kept low, that is, the suppression of white tobacco vapor can be achieved, and at the same time, most of the amines can be ensured. the desired volatilization of the tobacco content components.

Hereinafter, the respective tobacco materials (A) and (B) will be specifically described, but unless otherwise specified, various conditions or preferable ranges described in the respective tobacco materials can also be applied to other tobacco materials.

<Tobacco material (A)>

The raw material of the tobacco material (A) is not particularly limited, but at least one of (a) pulverized tobacco material, (b) moisture, and (c) the group consisting of potassium carbonate and sodium bicarbonate can be mentioned. and (d) at least one binder selected from the group consisting of polytridextrose and hydroxypropyl cellulose.

The pulverized tobacco material (component (a)) contained in the raw material of the tobacco material (A) contains pulverized tobacco leaves or pulverized tobacco sheets, the tobacco material (B) described later, and the like. Tobacco species include Burleigh species, yellow species, and oriental species. The pulverized tobacco material is preferably pulverized to an average particle size of 30 μm or more and 300 μm or less. The average particle diameter can be measured using a particle size distribution analyzer (eg, Master sizer manufactured by Spectris).

The moisture (component (b)) contained in the tobacco material (A) is for maintaining the integrity of the tobacco particles.

The raw material mixture of the tobacco material (A) usually contains moisture in an amount of 3% by weight or more and 13% by weight or less. In addition, the tobacco material (A) can usually contain moisture in an amount of 5% by weight or more and 17% by weight or less in terms of weight loss on drying. The so-called drying loss refers to the time when a part of the sample is collected for measurement, and the sample is completely dried by evaporating all the water in the collected sample (for example, when drying at a certain temperature (105°C) for 15 minutes. ) before and after drying, specifically, refers to the amount of water contained in the sample and the amount of volatile components that volatilize under the above drying conditions. The ratio (% by weight) of the cumulative value of the amount to the weight of the sample. That is, the drying loss (weight %) can be represented by the following formula (1).

Drying loss (wt%) = {(weight of sample before complete drying)-(weight of sample after complete drying)}×100/weight of sample before complete drying (1)

As the flavor development adjuvant (component (c)) contained in the tobacco material (A), the types described above can be used. The flavor development adjuvant adjusts the pH of the tobacco material (A) to the alkaline side, thereby promoting the release of flavor components contained in the tobacco material (A) from the tobacco particles, thereby producing a flavor that can be satisfied by the user .

Volatile fragrances can use any fragrance as the temperature can be around 100℃ A spice that expresses the characteristic of spice at low temperature. The so-called flavor sense system means that when a non-combustion heating cigarette is used, the flavor derived from the flavor can be sensed. The fragrance ingredient can be selected from 1-menthol, natural vegetable fragrance (for example, cognac oil, orange oil, jasmine oil, spearmint oil, peppermint oil, anise oil, coriander oil) ), lemon oil, chamomile oil, labdanum oil, vetiver oil, rose oil, lovage oil), esters (for example, menthyl acetate, isoamyl acetate, Agaryl acetate, isoamyl propionate, butyl butyrate, methyl salicylate, etc.), ketones (eg, menthone, ionone, ethyl maltol, etc.), alcohols (eg, phenylethyl alcohol, anethole, cis-6-nonen-1-ol, oleyl alcohol, etc.), aldehydes (eg, benzaldehyde, etc.), lactones (eg, ω-pentadecanolide, etc.) A sort of. Particularly preferred volatile flavors contained in the tobacco material include 1-menthol, anethole, methyl acetate, schoololeol, ω-pentadecalactone, and cis-6-nonen-1-ol. Alternatively, the volatile flavoring system contained in the tobacco material may be used by mixing two or more selected from the above-mentioned group.

The volatile flavoring system contained in the tobacco material (A) can be used as a solid, or dissolved or dispersed in a suitable solvent such as ethanol, benzyl alcohol, and water. Preferably, a fragrance that is easily dispersed in a solvent by adding an emulsifier can be used. For example, a hydrophobic fragrance or an oil-soluble fragrance can be used. These fragrance ingredients may be used alone or in combination.

The raw material mixture of the tobacco material (A) can usually contain the above-mentioned flavor material in an amount of not less than 0.5% by weight and not more than 30% by weight. The above-mentioned fragrance material can be added to the above-mentioned components by directly kneading with the components (a), (b), (c), and (d), or can be added to a known inclusion host compound such as cyclodextrin ( host compound) to prepare the inclusion compound, which is combined with the above kneaded in separate parts to be added to the above-mentioned ingredients. Moreover, after producing the tobacco material (A) without adding the flavor material, the flavor material dissolved in the solvent may be added by spraying.

The content of the flavor in the tobacco material (A) obtained from the above-mentioned raw material mixture is not particularly limited, but from the viewpoint of imparting a good flavor, it is usually 100 ppm or more, preferably 1,000 ppm or more, more preferably 5,000 ppm or more, and , usually 100,000 ppm or less, preferably 40,000 ppm or less, and even more preferably 25,000 ppm or less.

Tobacco material (A) is to mix components (a), (c) and (d) and desired component (e), add component (b) to the mixture and knead it, and then use a wet extrusion granulator to granulate all of the components. After the obtained kneaded product is granulated (long columnar shape), it is granulated into a short columnar shape or a spherical shape to obtain it.

The extrusion pressure at the time of extrusion granulation can be arbitrarily set according to the viscosity of the kneaded product and the like. For example, an aspect in which the kneaded product is extruded at ambient temperature and a pressure of 2 kN or more can be mentioned. By extruding at such a high pressure, the temperature of the kneaded material at the outlet of the extrusion granulator suddenly rises sharply from the ambient temperature to, for example, 90°C or more and 100°C, and the moisture and volatile components are divided by 2 wt. % or more and 4% by weight or less are evaporated. Therefore, when performing extrusion granulation in this manner, it is required to make the water prepared for the kneaded product to be larger than the desired amount of water in the obtained tobacco granules by the above-mentioned evaporation amount.

To adjust the moisture, the tobacco granules obtained by extrusion granulation can be refrigerated as required. For example, when the drying loss of tobacco particles obtained by extrusion granulation is measured, which is higher than the desired drying loss (for example, 5 wt % or more and 17 wt % or less), in order to obtain the desired drying loss Tobacco particles can be dried again if desired to be reduced in drying. In order to obtain the drying conditions (temperature and time) of the desired drying weight loss, the drying conditions (temperature and time) necessary for reducing the drying weight loss by a predetermined value can be determined in advance and set according to the conditions.

<filter part>

The non-combustion heating type cigarette of this embodiment has a first filter part and a second filter part, but there is no difference between them, and either filter part is used as the suction side or the heater side can be used according to the following The form of the electrically heated cigarette product used at the time of use is arbitrarily determined by the user. In the following description of the filter part, unless otherwise stated, it is applicable to either the first filter part or the second filter part. Moreover, the structure of a 1st filter part and the structure of a 2nd filter part may be different from the range which can be used, and may be the same.

The filter part includes the part of the filter described later, and it is not particularly limited as long as it has the function of a general filter. For example, it may be composed of only a single segment composed of a filter, or a combined filter and other members. composed of plural segments.

Moreover, the filter part which contains the additive release container mentioned later can be used as a filter part.

The sizes of the first filter portion and the second filter portion are not particularly limited, and can be appropriately set according to the shape of the non-combustion heating cigarette used during use or the shape of the electrically heated cigarette product used during use, but for example , can take the following form. In the filter portion, the length in the longitudinal direction of the non-combustion heating cigarette is referred to as the "height".

From the viewpoint of ensuring good ventilation resistance, the height of each filter portion is usually 3 mm or more, preferably 4 mm or more, and usually 15 mm or less, preferably 10 mm or less.

When the non-combustion heating cigarette is a columnar body, the filter part also becomes a columnar body, but its diameter (width) is theoretically smaller than the width w of the bottom surface of the columnar body of the non-combustion heating cigarette. The value of twice the thickness of , plus the width of the filter portion of the columnar body is used as the width w of the bottom surface of the columnar body of the non-combustion heating cigarette.

As the material of the filter, a cellulose ethyl acetate bundle is processed into a cylindrical shape. Compared with general combustion cigarettes, the non-combustion heating cigarette according to the embodiment of the present invention preferably has a smaller amount of tobacco vapor removed in the filter portion. From such a viewpoint, in the case of a non-combustion heating type cigarette with a circumference of 24.5 mm, the monofilament fineness of the cellulose ethyl acetate bundle is 5 g/9000 m or more and 20 g/9000 m or less, preferably 5 g/9000 m or more and 12 g/9000 m or less. The total fineness is 12000g/9000m or more and 35000g/9000m or less, preferably 12000g/9000m or more and 28000g/9000m or less. Further, the fiber packing density is preferably 0.09 g/cc or more and 0.12 g/cc or less. The cross-sectional shape of the fiber of the cellulose ethyl acetate bundle may be a Y cross section or an R cross section. In the case of a filter filled with cellulose ethyl acetate bundles, in order to increase the filter hardness, 5 wt % or more and 10 wt % or less of triacetin may be added relative to the weight of the cellulose ethyl acetate bundle.

Moreover, as the method of processing the cellulose ethyl acetate bundle into a cylindrical shape, the method of winding up the cellulose ethyl acetate bundle with the winding paper for a filter can also be used. The physical properties of the filter winding paper are not particularly limited, but, for example, a high-air-permeability paper having an air permeability of 1000 C.U. or more or a low-air permeability paper having an air permeability of less than 100 C.U. is used. In addition, as the filter wrapping paper, a wrapping paper used for a normal cigarette filter can be used, for example, one having a basis weight of 30 to 100 g/m ² and a thickness of 30 to 100 μm can be used. Such a high air permeability paper is not particularly limited, but LPWS-OLL (air permeability 1300 C.U., basis weight 26.5 gsm, thickness 48 μm), P-10000C (air permeability 10000 C.U., basis Weight 24.0gsm, thickness 60μm), or, plain paper (air permeability 0C.U., basis weight 24gsm, thickness 32μm).

Moreover, in addition to the filter which consists of bundles, such as the ethyl acetate bundle mentioned above, the form of the filter which fills the paper which contains pulp as a main component, or a nonwoven fabric sheet may be sufficient.

In the manufacture of the filter material, the adjustment of the ventilation resistance and the addition of additives (known sorbents, fragrances, fragrance-retaining materials, etc.) can be appropriately designed.

As described above, the first filter portion and the second filter portion may be constituted by a single segment, respectively, or may be constituted by a plurality of segments. When the first filter part and/or the second filter part is composed of a plurality of segments, the above-mentioned winding paper is wound around these to constitute a non-combustion heating type cigarette.

When the first filter part and/or the second filter part is constituted by a single segment, for example, the filter part may be constituted only by a filter filled with cellulose ethyl acetate bundles, or only by a filter filled with pulp. The form of a filter made of paper or non-woven fabric as the main component. Moreover, the aspect in which the additive release container mentioned later is contained in these filters can also be mentioned.

One aspect in which the first filter part and/or the second filter part is composed of plural segments can be an aspect in which the plural segments are composed of plural identical or different filters. In this case, the filter may be filled with the above-mentioned ethyl acetate bundle, may be filled with a paper or nonwoven sheet mainly composed of pulp, or may include an additive release container described later.

Moreover, another aspect which the 1st and 2nd filter part consists of a plurality of segments is an aspect which consists of a filter and other members. The above-mentioned "members other than those" are not particularly limited, but for example, a paper tube obtained by processing a cardboard into a cylindrical shape can be mentioned. For example, in order to extend the length of the non-combustion heating type cigarette in the long axis direction, if the length of the tobacco filling section (space part) is increased, it is necessary to arrange If the tobacco material is more than necessary, if the length of the filter is increased, the ventilation resistance of the filter part will increase, which will affect the ease of inhalation. At this time, if a paper tube is used, the length in the longitudinal direction of the non-combustion heating cigarette can be adjusted without the above-mentioned influence.

Either of the first filter portion and the second filter portion may contain a breakable additive release container (eg, a capsule) comprising a breakable shell of pectin or the like. At this time, the filter portion containing the additive release container becomes the suction port side. If the capsule is destroyed by the user of the non-combustion heated cigarette before, during, or after use, the liquid or substance (usually, the flavouring material) contained in the capsule is released, which then releases the liquid or substance contained in the capsule. The smoke delivered to the tobacco during use of the non-combustion heated cigarette is delivered to the surrounding environment after use.

The shape of the additive release container is not particularly limited, and for example, it may be a capsule such as a fragile capsule, and the shape of the container is preferably a sphere. The additive contained in the additive release container may contain any of the above-mentioned additives, but in particular, it is preferable to contain a fragrance material or activated carbon. In addition, as an additive, one or more kinds of materials that contribute to filtering smoke may be added. The form of the additive is not particularly limited, but is usually liquid or solid. Also, the use of capsules containing additives is well known in the art. Fragile capsules and methods of making the same are well known in the art.

As a flavor material system, menthol, spearmint, peppermint, fenugreek (Fenugreek), cloves, etc. may be sufficient, for example. Fragrances can be used alone, or a combination of these can be used.

<additional segment>

As shown in FIGS. 2A and 2B , the above-mentioned non-combustion heating cigarette 1 can be attached to the paper 26 and the additional segment provided adjacent to the first filter portion 21 and/or the second filter portion 22 by an additional segment. 25 are packaged together. By providing additional segments 25, further functionality can be added to the non-combustion heated cigarette.

The form of the additional segment is not particularly limited, for example, it can be a filter or a paper tube. By having a filter as an additional segment, ventilation resistance can be increased. In addition, from the viewpoint that the distance between the electrically heated cigarette product into which the non-combustion heating cigarette is inserted and the mouth of the user is better to ensure a certain length, the filter portion on the side of the suction mouth is provided with a paper tube as a function. The additional segment can improve the ease of operation during use, such as the ease of smoking.

Furthermore, when a filter is provided as an additional segment in the filter portion on the suction side, an additive release container may be provided inside the filter.

The aspects of the filter, the paper tube, and the additive release container are similarly applicable to the aspects described in the above-mentioned filter section, and the effects thereof are as described in the above-mentioned filter section.

The additional segment bonding paper is not particularly limited as long as it can join the non-combustion heated cigarette and the additional segment, but for example, tipping paper (Tipping paper or Tip paper, also known as tipping paper) can be used.

The shape of the tipping paper is not particularly limited, and known tipping papers can be used.

The form of the tipping paper when wrapping is not particularly limited. For example, as shown in FIG. 2A , it may be wrapped so as to cover a part of the non-combustion heated cigarette and the entirety of the additional segment. , as shown in FIG. 2B , may also be a form of wrapping so as to cover a portion of the non-combustion heated cigarette and a portion of the additional segment.

<Nozzle>

The non-combustion heated cigarette may be fitted with a mouthpiece. Even if the mouthpiece is not used, the non-combustion heated cigarette can be used, but at this time, since the non-combustion heated cigarette will be in direct contact with the user's mouth, the Cigarettes, especially the filter on the suction end side, are prone to wetting. Therefore, there arises a problem that the ventilation resistance increases, and also a problem that the touch feeling deteriorates. In order to improve these problems, it is preferable to use a suction nozzle.

In addition, in terms of ease of handling during use, such as ease of smoking, it is preferable to ensure a certain length of distance between the electrically heated cigarette product into which the non-combustion heated cigarette is inserted and the user's mouth. Therefore, in this regard, it is better to use a suction nozzle.

In addition, the mouthpiece may be directly engaged with the non-combustion heating cigarette, but may be indirectly engaged through the above-mentioned additional segment.

The material of the suction nozzle is not particularly limited, and may be any of a polymer material such as resin or rubber, a metal material, or an inorganic material, but is preferably a resin from the viewpoint of ease of manufacture and light weight.

The shape of the suction nozzle is not particularly limited as long as it is a flow path s2 that can ensure the circulation of the tobacco vapor that the user sucks. From the point of view, it is better to taper on the side of the suction port, as shown in FIG. 4, it is not uniformly thinned, and it is preferable to be in line with the shape of the user's lips, and the long axis direction of the side of the suction port is positive. The shape of the intersecting section becomes thinner in such a way that it becomes a flat shape.

The part is fitted here, but from the viewpoint of preventing the suction nozzle from falling out during use, the fitted form is preferable.

In addition, as described above, by providing a protrusion or the like on the suction nozzle, the engagement between the non-combustion heating type cigarette and the suction nozzle is enhanced. Electric heating devices are preferred since non-combustion heating cigarettes and mouthpieces are removed. Specifically, it is preferable that the static frictional force acting between the mouthpiece and the non-combustion heating cigarette is greater than the static frictional force acting between the inner wall of the electric heating device and the non-combusting heating cigarette.

The electrically heated cigarette product may have other structures than the above-mentioned structures, and the other structures include, for example, a temperature sensor, a gas component concentration sensor (chemical sensor), and the like.

The same flow rate was carried out) to confirm the tobacco vapor generated from the oral cavity of the sensory examiner, and from the starting point, the smoking and the confirmation of the tobacco vapor were repeated once every 30 seconds. Visual confirmation of smoking and tobacco vapour terminated the trial. Finally, the visibility of tobacco vapor was evaluated according to the following evaluation criteria. The evaluation results are shown in Table 1.

(assessment benchmark)

0: No tobacco vapor is seen.

1: Tobacco vapor is vaguely visible.

2: No tobacco vapor is seen at all.

[Table 1]

In Examples 1 and 2 below % by weight, compared with Comparative Example 1 in which the concentration was 30% by weight, the cumulative value of the evaluation value of the visibility of the tobacco vapor of all the sensory inspectors was low.

In addition, it can be seen that in Example 1 in which the amount of glycerin (mist generating base material) added to the tobacco material was 0% by weight, the tobacco vapor could not be visually recognized at all at any of the heater temperatures of 180°C and 190°C. .

<Experiment II; Determination of Particle Count in Tobacco Vapor>

Using the non-combustion heating cigarette of Example 1, the number concentration of particles in the tobacco vapor was measured according to the test system shown in FIG. 7 . For the measuring device, use APS SPECTROMETER model 3321 (manufactured by TSI Corporation) with a measurable particle diameter range of 0.5 or more and 20 μm or less, and a measurable particle concentration of 0.001 particles/cc or more and 1000 particles/cc or less. After that, it is measured rapidly (0 to 2 seconds), and the number concentration of particles is calculated from the volume frequency distribution (volume ratio).

Specifically, after 3 minutes had elapsed from the time when the temperature of the non-combustion heating cigarette was raised to 120° C. (the time of temperature increase), smoking was started, and a single discarding puff (55 ml/2sec, and the following puffs were the same) 3 minutes and 30 seconds have elapsed from the heating time point (the evaluation start time point) to perform suction once, to measure the number of particles in the tobacco vapor, and repeat every 30 seconds from the start time point The puff and the measurement of the number of particles in the tobacco vapor were performed once, and the fifth puff and the measurement of the number of particles in the tobacco vapor were completed.

The measurement results of the three measurements are shown in FIG. 8 , and Table 2 shows the results of calculating the average value of each suction for these measurement results.

[Table 2]

From Table 2 and FIG. 8, it can be seen that the content of particles with a particle diameter of 0.5 μm or more and 20 μm or less in the tobacco vapor is at most 160 particles per puff, and the content of particles of 5 μm or more and 20 μm or less was not observed. Therefore, it was found that the content of the mist in the tobacco vapor was 160 pieces/puff or less. In addition, most of the particles in the tobacco vapor have a particle size of 1 μm or more and less than 2.5 μm.

In Example 1, since the mist generating substrate was not externally added, the generated mist was considered to be derived from the mist generating component contained (internally) contained in the raw material of the original tobacco material.

It can be seen that the average of the total number of particles obtained in the five suction measurements described above is about 100 particles/suction. From this situation, the results of the number per cc volume were calculated and shown in Table 3. In addition, the number and concentration of "paper-rolled cigarettes" in Table 3 are cited and described in the prior art document (sheet Shan et al.: "Measurement of changes in properties of mainstream tobacco smoke obtained by laser light scattering, J. Aerosol Res., 20 (4), 345-351 (2005)) value.

[table 3]

From Table 3, it can be seen that the number concentration of particles in the tobacco vapor of Example 1 using the non-combustion heating cigarette of the present embodiment is extremely lower than the number concentration of particles in the tobacco vapor of the paper cigarette.

From the above Experiments I and II, it can be seen that by using the non-combustion heating cigarette according to the present embodiment, visible suppression of tobacco vapor can be achieved by a method different from the method of limiting the heating temperature during use.
