Description

Technical Field

[0001] The invention relates to a non-combustion heating smoking article and a non-combustion heating smoking system. Background Art

[0002] Common combustion smoking articles (tobacco) for smoking by burning have a tobacco-containing segment formed by rolling tobacco filler into a cylindrical shape with a paper packaging material, and a mouthpiece segment formed by rolling fibers formed of cellulose acetate or the like or paper with pleats into a cylindrical shape with a paper packaging material, wherein the above-mentioned tobacco filler is obtained by adding flavoring, moisturizing agent and appropriate moisture to dry tobacco leaves cut into a width of about 1 mm. The above-mentioned tobacco-containing segment and the above-mentioned mouthpiece segment are connected together by lining paper. The smoker ignites the end of the above-mentioned tobacco-containing segment with a lighter, etc., and draws from the end of the above-mentioned mouthpiece segment to smoke. The front end of the above-mentioned tobacco-containing segment burns at a temperature exceeding 800°C.

[0003] As an alternative to such conventional combustion smoking articles, non-combustion heating smoking articles and non-combustion heating smoking systems that utilize heating instead of combustion have been developed (e.g., patent documents 1 to 6). The heating temperature is lower than the combustion temperature in the combustion smoking article, for example, the heating is performed at a temperature below 400°C. In the non-combustion heating smoking article, the tobacco filler containing the tobacco segment contains an aerosol generating substrate such as glycerin, propylene glycol (PG), triethyl citrate (TEC), and triacetin. The aerosol generating substrate is vaporized by heating, and moves to the cooling section in the mouthpiece section by inhalation, and generates aerosol more reliably after cooling. When inhaling from the filter section at the end of the suction port side provided in the mouthpiece section, the aerosol is also inhaled together, thereby ensuring the smoker's satisfaction.

[0004] The non-combustion heating smoking system generally comprises: a cylindrical non-combustion heating smoking article having a shape similar to that of a normal combustion smoking article, and a heating device including a battery, a controller, a heater, etc. The heater may be a heater using a resistor, or a heater using IH. As a heating method using a heater using a resistor, there may be a method of heating the non-combustion heating smoking article from the outside with a heater; a method of inserting a needle-shaped or blade-shaped heater from the front end of the non-combustion heating smoking article into a tobacco-containing segment containing a tobacco filler to heat the article, etc.

[0013] Problems to be solved by the invention

[0014] As described above, the aerosol-generating substrate (hereinafter also referred to as the aerosol vaporized component) vaporized by heating is cooled mainly in the cooling section, and condensation from vapor to particles occurs to form an aerosol. Here, the aerosol vaporized component is required to be sufficiently cooled to allow the smoker to inhale from the filter section provided at the end of the mouth-side. As a cooling section for non-combustion heated smoking articles, for example, Patent Document 4 discloses the following structure: perforations are provided on the outer periphery of a hollow cylindrical portion, and external air is introduced from the perforations during inhalation, so that the aerosol vaporized component contacts the external air and is cooled.

[0015] However, the smoker's lips also feel hot when smoking. That is, even if the temperature of the vaporized components of the aerosol is lowered by cooling, the smoker will feel uncomfortable when the temperature of the mouthpiece is transmitted to the lips. Therefore, in order to obtain a satisfying smoking feeling, the smoker must feel a temperature suitable for smoking at the lips. In view of the above situation, the object of the present invention is to provide a non-combustion heating smoking article in which the smoker's lips feel a temperature suitable for smoking when smoking, and a non-combustion heating smoking system equipped with the non-combustion heating smoking article.

[0063] [Non-combustion heat-to-smoking articles]

[0064] The non-combustion heating smoking article of the present invention comprises: a tobacco-containing segment including tobacco and an aerosol generating substrate, a cylindrical cooling segment having perforations on the outer circumference, and a filter segment. The filter segment comprises: a filler, an inner filter plug forming paper wrapped around the filler, and an outer filter plug forming paper wrapped around the filler, wherein at least one of the inner filter plug forming paper and the outer filter plug forming paper has a unit area weight of 40 g / m 2Paper having a thickness of 100 μm or more. Figure 1 The outline of the present invention is shown. Figure 1 In the figure, 1 is a tobacco-containing segment, 3 is a cooling segment, 5 is a filter segment, 5in is an inner filter plug forming paper, and 5out is an outer filter plug forming paper. The gasified aerosol component generated in the tobacco-containing segment 1 is cooled in the cooling segment 3 to become an aerosol, and is introduced into the filter segment 5. In the present invention, the packaging material constituting the filter segment 5 has a specific unit area weight and thickness, and therefore exhibits excellent heat insulation. Therefore, the smoker's lips feel a temperature suitable for smoking.

[0065] Figure 2 A preferred embodiment of the non-combustion heat-and-smoking article of the present invention is shown. In the figure, 20 is a non-combustion heat-and-smoking article, 1 is a tobacco-containing segment, and 2 is a mouthpiece segment. The mouthpiece segment 2 includes: a cooling segment 3, a center hole segment 4, and a filter segment 5. Sometimes the center hole segment 4 and the filter segment 5 are combined and referred to as a "filter portion". When smoking, the tobacco-containing segment 1 is heated and inhaled from the end of the filter segment 5.

[0066] The tobacco-containing segment 1 comprises: a tobacco filler 6 containing tobacco and an aerosol-generating substrate, and a tubular packaging material 7 that wraps the tobacco filler 6. The tobacco filler 6 may further contain volatile flavoring components and water. The size of the tobacco used as the filler and its preparation method are not limited. For example, the dried tobacco leaves can be cut into shredded tobacco with a width of 0.8 to 1.2 mm. When cut into the above-mentioned width, the length of the shredded tobacco is about 5 to 20 mm. In addition, the dried tobacco leaves can be crushed to an average particle size of about 20 to 200 μm and homogenized for sheet processing, and cut into shredded tobacco with a width of 0.8 to 1.2 mm. When cut into the above-mentioned width, the length of the shredded tobacco is about 5 to 20 mm. In addition, the tobacco processed into the above-mentioned sheets can also be collected and processed for use as a filler without being cut. In addition, a plurality of cylindrical sheets can be arranged in concentric circles. When the dried tobacco leaves are cut and used, in the same manner, when the tobacco leaves are used in the form of pulverized and homogenized sheets, various types of tobacco can be used as the tobacco filler. Yellow, white rib, oriental, local, and other Nicotiana tabacum and Nicotiana rustica varieties can be appropriately mixed to achieve the target taste. The details of the above tobacco varieties are disclosed in "Tobacco Dictionary, Tobacco Comprehensive Research Center, 2009.3.31".

[0067] There are several existing methods for crushing tobacco and processing it into homogenized sheets. The first is a paper-made sheet made by papermaking technology, the second is a cast sheet made by mixing with a suitable solvent such as water and homogenizing it, casting it on a metal plate or metal strip into a thin homogenized product, and drying it, and the third is a rolled sheet obtained by mixing with a suitable solvent such as water and homogenizing it, and then extruding it into a sheet. Details of the types of the above-mentioned homogenized sheets are disclosed in "Tobacco Encyclopedia, Tobacco Comprehensive Research Center, 2009.3.31".

[0068] The filling density of the tobacco filler 6 is not particularly limited, but is generally 250 mg / cm 3 from the viewpoint of ensuring the performance of the non-combustion heat-and-smoking article 20 and imparting a good smoking taste. 3 Above, preferably 320 mg / cm 3 Above, in addition, usually 520mg / cm 3 Below, preferably 420 mg / cm 3 Specifically, in the case of a tobacco-containing segment 1 having a circumference of 22 mm and a length of 20 mm, the content of the tobacco filler 6 in the tobacco-containing segment 1 can be set to 200 to 450 mg per tobacco-containing segment, preferably 280 to 400 mg.

[0069] The aerosol generating substrate is a material that can generate an aerosol by heating, and is not particularly limited, and examples thereof include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1,3-butylene glycol, etc. These may be used alone or in combination of two or more.

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

[0071] The content of the aerosol generating substrate in the tobacco filler 6 is not particularly limited, but is generally 5 to 50% by mass, preferably 10 to 20% by mass, from the viewpoint of sufficiently generating aerosol and imparting a good inhalation taste. In the case where the tobacco filler 6 contains a volatile flavor component, the content of the volatile flavor component in the tobacco filler is not particularly limited, but is generally 10,000 ppm or more, preferably 20,000 ppm or more, more preferably 25,000 ppm or more, relative to the mass of the tobacco filler, from the viewpoint of imparting a good inhalation taste, and is generally 50,000 ppm or less, preferably 40,000 ppm or less, more preferably 33,000 ppm or less.

[0072] The method of filling the tobacco filler 6 into the packaging material 7 is not particularly limited. For example, the tobacco filler 6 may be wrapped with the packaging material 7, or the tobacco filler 6 may be filled into the cylindrical packaging material 7. When the shape of the tobacco has a longitudinal direction like a rectangle, the tobacco may be filled in such a manner that the longitudinal direction of the tobacco becomes an unspecified direction in the packaging material 7, or may be filled in such a manner that the tobacco is arranged in the axial direction of the tobacco-containing segment 1 or in a direction perpendicular to the axial direction. By heating the tobacco-containing segment 1, the tobacco components, aerosol-generating substrate, and water contained in the tobacco filler 6 are vaporized, and moved to the mouthpiece segment 2 by inhalation.

[0073] The cooling section 3 is composed of a cylindrical member 8. The cylindrical member 8 can be, for example, a paper tube obtained by processing thick paper into a cylindrical shape. The cylindrical member 8 and the later-described cigarette holder lining paper 15 can be provided with perforations 9 that penetrate the two. Through the perforations 9, air is introduced from the outside into the cooling section 3 during inhalation. As a result, the aerosol gasification component generated by heating the tobacco-containing section 1 contacts the external air, and its temperature is reduced, thereby liquefying to form an aerosol. The diameter (diameter length) of the perforation 9 is not particularly limited, and can be, for example, 0.5 to 1.5 mm. The number of perforations 9 is not particularly limited, and can be one or more than two. For example, a plurality of perforations 9 can be provided on the periphery of the cooling section 3. Relative to the overall volume of the gas inhaled by the smoker, the amount of external gas introduced from the perforations 9 is preferably less than 85% by volume, and more preferably less than 80% by volume. The lower limit is preferably more than 55% by volume, and more preferably more than 60% by volume. By setting the ratio of the external air amount to be within this range, it is possible to sufficiently suppress a reduction in the aroma and taste due to dilution with the external air.

[0074] The center hole segment is formed by a filling layer having a hollow portion, and an inner filter rod forming paper covering the filling layer. For example, the center hole segment 4 is composed of a first filling layer 10 having a hollow portion, and a first inner filter rod forming paper 11 covering the first filling layer 10. The center hole segment 4 also has the function of increasing the strength of the mouthpiece segment 2. The first filling layer 10 is filled with, for example, cellulose acetate fibers at a high density, and a plasticizer containing triacetin can be added at 6 to 20% by mass relative to the mass of cellulose acetate to solidify it into a hollow rod. The filling density of the fibers of the first filling layer 10 is high, so during inhalation, air and aerosol only flow in the hollow portion and hardly flow in the first filling layer 10. The first filling layer 10 inside the center hole segment 4 is a fiber filling layer, so the touch from the outside rarely makes the smoker feel uncomfortable during use. It is preferred to further wrap the center hole segment 4 with an outer filter rod forming paper 14. As Figure 2 As shown, the outer plug wrap 14 can be wrapped around the central hole segment 4 and the filter segment 5 at the same time.

[0075] The structure of the filter segment in the present invention is not particularly limited, for example Figure 2 Like the filter tip segment 5, the second filling layer 12 and the second inner filter plug forming paper 13 ( Figure 1 5in), and an outer filter plug forming paper 14 ( Figure 1 In the filter segment 5, the second filling layer 12 exists until the end of the mouthpiece, so the end has the same appearance as a common smoking article.

[0076] At least one of the inner filter plug forming paper 13 and the outer filter plug forming paper 14 has a unit area weight of 40 g / m 2 The paper is made of a material having a thickness of 100 μm or more and a weight per unit area of ​​60 g / m2 or more. Such paper has a relatively large weight per unit area and is relatively thick, so it has good heat insulation properties, and when smoking, the smoker's lips will feel a temperature suitable for smoking. From this point of view, it is preferred that both the inner filter rod forming paper and the outer filter rod forming paper are made of the above-mentioned paper. The weight per unit area is more preferably 60 g / m2. 2 The upper limit is not limited, but preferably 150 g / m 2 Below, more preferably 130g / m 2 The thickness is more preferably 110 μm or more, and there is no upper limit, preferably 150 μm or less, and more preferably 130 μm or less. When the weight per unit area and the thickness are within this range, the manufacture of non-combustion heating smoking articles also becomes easy. In order to further improve the insulation efficiency, it is preferred that one or both of the inner filter rod forming paper 11 or the outer filter rod forming paper 14 constituting the center hole segment 4 are also composed of the above-mentioned paper. The center hole segment 4 and the filter tip segment 5 can be connected together with a sheet of outer filter rod forming paper 14.

[0077] The circumference of the filter segment 5 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and further preferably 21 to 23 mm. Figure 2 The length of the filter segment 5 in the horizontal direction is not particularly limited, and is preferably 3 to 15 mm, and more preferably 5 to 10 mm. The shape of the cross section of the filter segment 5 is not particularly limited, and may be, for example, circular, elliptical, polygonal, or the like.

[0078] The tobacco-containing segment 1 and the cooling segment 3, as well as the connected center hole segment 4 and the filter segment 5 are connected together through the cigarette end lining paper 15. They can be connected by, for example, applying a paste such as vinyl acetate paste on the inner side of the cigarette end lining paper 15, inserting the above three segments and winding them.

[0079] The axial direction of the non-combustion heating smoking article of the present invention, i.e. Figure 2 The length in the horizontal direction is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and further preferably 50 mm to 60 mm. In addition, the circumference of the non-combustion heating type smoking article is preferably 16 mm to 25 mm, more preferably 20 mm to 24 mm, and further preferably 21 mm to 23 mm. For example, the length of the tobacco-containing segment 1 is 20 mm, the length of the cooling segment 3 is 20 mm, the length of the center hole segment 4 is 8 mm, and the length of the filter segment 5 is 7 mm. The length of the filter segment 5 can be selected within the range of 4 to 10 mm, and the ventilation resistance of each segment of the filter segment 5 can be selected to be 15 to 60 mmH. 2 O / seg. The lengths of these segments can be appropriately changed according to manufacturing suitability, required quality, etc. In addition, even if the center hole segment is not used and only the filter segment is arranged on the downstream side of the cooling segment, it can also function as a non-combustion heating smoking article.

[0080] [Non-combustion heating smoking system]

[0081] The non-combustion heating smoking system of the present invention comprises: the non-combustion heating smoking article of the present invention, and a heating device for heating the tobacco-containing segment. The above-mentioned non-combustion heating smoking system comprises the non-combustion heating smoking article of the present invention, so that the aerosol vaporized component can be fully cooled without impairing the aroma and taste. The non-combustion heating smoking system of the present invention is not particularly limited as long as it comprises the non-combustion heating smoking article of the present invention and the above-mentioned heating device, and may also have other structures.

[0082] An example of the non-combustion heating smoking system of the present invention is shown in Figure 3 . Figure 3The illustrated non-combustion heat-and-smoking system includes: a non-combustion heat-and-smoking article 20 of the present invention, and a heating device 21 for heating the tobacco-containing segment of the non-combustion heat-and-smoking article 20 from the outside. Figure 3 (a) shows the state before the non-combustion heating smoking article 20 is inserted into the heating device 21, Figure 3 (b) shows a state where the non-combustion heat-to-smoking article 20 is inserted into the heating device 21 and heated. Figure 3 The heating device 21 shown includes: a main body 22, a heater 23, a metal tube 24, a battery unit 25, and a control unit 26. The main body 22 has a cylindrical recess 27, and the heater 23 and the metal tube 24 are arranged on the inner side surface of the recess 27 at a position corresponding to the tobacco-containing segment of the non-combustion heated smoking article 20 inserted into the recess 27. The heater 23 can be a heater using resistance, and the heater 23 is heated by instructions from the control unit 26 that controls the temperature and by supplying power using the battery unit 25. The heat released from the heater 23 is transferred to the tobacco-containing segment of the non-combustion heated smoking article 20 through the metal tube 24 with high thermal conductivity. Figure 3 (b) is schematically illustrated, so there is a gap between the outer periphery of the non-combustion heat-smoking article 20 and the inner periphery of the metal tube 24, but in fact, for the purpose of efficient heat conduction, it is more desirable that there is no gap between the outer periphery of the non-combustion heat-smoking article 20 and the inner periphery of the metal tube 24. It should be noted that the heating device 21 can heat the tobacco-containing section of the non-combustion heat-smoking article 20 from the outside or from the inside.

[0083] The heating temperature by the heating device is not particularly limited, but is preferably 400° C. or less, more preferably 150° C. or more and 400° C. or less, and further preferably 200° C. or more and 350° C. or less. The heating temperature refers to the temperature of the heater of the heating device.

[0084] Example

[0085] [Example 1 and Comparative Examples 1 and 2]

[0086] Prepared as Figure 2 The non-combustion heat-and-smoking article shown is a 55 mm long heat-and-smoking article made by sequentially joining a tobacco-containing segment, a cooling segment, a center hole segment, and a filter segment. The dimensions of each segment are shown in Table 1.

[0087] [Table 1]

[0089] Containing tobacco segment Cooling section Center hole section Filter segment Length(mm) 20 20 8 7 Outer diameter(mm) 7.0 6.9 6.9 6.9 Inner diameter(mm) - 6.5 4.0 -

[0090] On the periphery of the cooling section, 15 perforations are arranged in a row around the periphery. The perforations are arranged at equal intervals so that Vf becomes about 70% by volume. Vf is defined by the amount of external gas introduced from the perforation 9 / the total amount of gas inhaled by the user. The distance from the joint surface of the cooling section and the center hole section to the perforation is set to 2 to 4 mm.

[0091] The non-combustion heat-and-smoke smoking article was heated, and a smoking test was conducted by a fully trained panel of five people for sensory evaluation of the smoking article. The temperature felt on the lips was evaluated according to the following criteria.

[0092] 1: Very suitable for smoking

[0093] 2: Very suitable for smoking

[0094] 3: Suitable for smoking

[0095] 4: Slightly suitable for smoking

[0096] 5: Not suitable for smoking

[0097] Specifically, a panel of five people smoked existing commercially available burning tobacco, and the sensory temperature felt by the lips at this time was set as "1: very suitable for smoking" to achieve a unified standard, and then the non-combustion heating smoking articles of each example were evaluated.

[0098] The filter segment of the non-combustion heated smoking article is connected to the smoking machine through a tube. A thermocouple is attached to the outer periphery of the tube, and the front end of the thermocouple is 7 mm away from the mouthpiece end and is arranged on the surface of the non-combustion heated smoking article. The tobacco-containing segment of the above-mentioned non-combustion heated smoking article is heated by a heater, and inhaled by the above-mentioned smoking machine. The heating by the heater is maintained at 230°C for 50 seconds, and after being maintained at 200°C for 130 seconds, it is maintained at 170°C. The inhalation is carried out as follows: Based on the CIR method (Canadian mandatory smoking conditions method), the average suction is set to 55ml / 2 seconds (30 seconds between each suction, that is, 2 seconds of suction and 28 seconds of standby), and a total of three suctions are performed. The maximum temperature from the temperature of each suction is recorded as the tipping paper (tip) temperature. The results are shown in Table 2.
