Description

Non-combustion heating smoking articles and non-combustion heating smoking system

The present invention relates to a non-combustion heating smoking article and a non-combustion heating smoking system.

The usual burning smoking article (tobacco) that uses burning to smoke is: the tobacco is made by adding fragrance, humectant and moderate moisture to the dried tobacco leaves cut to about 1mm width by using paper roll paper The filler roll is a cylindrical tobacco-containing segment, and the fiber composed of cellulose acetate or the paper roll after pleating treatment is packed into a cylindrical interface segment by a paper roll. The aforementioned tobacco-containing segment and the aforementioned interface segment are connected by a backing paper. The user ignites the end of the tobacco-containing segment with a lighter or the like, and inhales from the end of the interface segment, thereby smoking. The front end of the aforementioned tobacco-containing section is burned at a temperature exceeding 800°C.

At present, non-combustion heating smoking articles and non-combustion heating smoking systems that use heating instead of combustion have been developed as substitutes for such conventional burning smoking articles (for example, Patent Documents 1 to 6). The heating temperature is lower than the burning temperature in the burning smoking article, for example, heating is below 400°C. Among non-combustion heating smoking articles, tobacco fillers containing tobacco segments contain glycerin, propylene glycol (PG: Propylene Glycol), triethyl citrate (TEC: Triethyl Citrate), Aerosol (also known as aerosol) such as glycerol triacetate generates a substrate. The mist generating substrate is vaporized by heating, moves to the cooling section in the interface section by inhalation, and is cooled to generate mist more reliably. When inhaling from the filter segment at the end of the mouth side provided in the interface segment, since the mist is also inhaled, the user's satisfaction can be ensured.

Generally speaking, a non-combustion heating smoking system is provided with a cylindrical non-combustion heating smoking article having a shape similar to a normal burning smoking article, and a heating device including a battery, a controller, and a heater. The heater can be a heater based on the resistance method or a heater based on the IH method. The heating method of the heater based on the resistance method can include: heating the smoking article from the outside of the non-combustion heating by the heater, or inserting a needle-shaped or scraper-shaped heater from the tip of the non-combustion heating smoking article Methods of heating in tobacco-containing segments containing tobacco fillers, etc.

[Non-combustion heating smoking articles]

The non-combustion heating smoking article of the present invention includes a tobacco-containing section containing tobacco and a mist generating substrate, a cylindrical cooling section with perforations on the periphery, and a filter section. Here, while closing the perforation and heating the tobacco-containing section with the following temperature distribution, smoking is performed for 5 puffs according to the HCI Act (Canadian Compulsory Smoking Conditions Act) 40 seconds after the heating starts At the time, the mass increase of the aforementioned filter segment after smoking relative to the aforementioned filter segment before smoking (hereinafter also simply referred to as "mass increase") is 4.0 to 7.9 mg.

In the present invention, by smoking for 5 puffs under the aforementioned conditions, the mass of the filter segment after smoking relative to the mass of the aforementioned filter segment before smoking is increased to 4.0 to 7.9 mg, which does not impair the aroma and taste. The vaporized components of the mist are sufficiently cooled. The aforementioned mass increase can be presumed to be caused by mist or water vapor being trapped in the filter segment. In the present invention, by increasing the aforementioned mass to 4.0 mg or more, since mist or water vapor can be sufficiently captured in the filter segment, heat can also be captured together. In addition, the captured mist or water vapor shows a cooling effect. Therefore, a higher cooling effect can be obtained in the filter segment. In addition, by increasing the mass to 7.9 mg or more, it is possible to prevent the mist from being unnecessarily captured, and the tobacco components or flavor components contained in the mist can be sufficiently supplied to the user, so the aroma will not be impaired. Furthermore, even in the case of cooling by external air introduced from the perforation provided in the cooling section, since the cooling effect is obtained in the filter segment, the amount of external air introduced from the perforation can be reduced. Get a full smell. The details of the present invention will be described below.

In the present invention, the aforementioned mass increase is 4.0 to 7.9 mg, preferably 5.0 to 7.5 mg, and more preferably 6.0 to 7.0 mg. The aforementioned mass increase is described later, and can be appropriately adjusted according to, for example, the material of the filler filled in the filter segment, the filling amount, the air permeability resistance of the filter segment, etc. whole. In addition, as in the aforementioned case, the aforementioned mass increase can be presumed to be caused by the trapping of mist or water vapor in the filter segment. As the number of suctions increases, the aforementioned mass increase becomes larger.

The aforementioned mass increase can be measured according to the following method. The filter section of the non-combustion heating smoking article after the perforation of the cooling section is closed is connected to the smoking machine through the pipe. The tobacco-containing section of the non-combustion heating smoking article is heated by a heater, and the smoking machine is used for smoking. The heating by the heater was maintained at 230°C for 50 seconds, and then at 200°C for 130 seconds, and then at 170°C. In addition, these temperatures indicate the set temperature of the heater. The inhalation system starts 40 seconds after the heating starts. According to the HCI Act (Canadian Compulsory Smoking Conditions Act), each puff is set to 55ml/2 seconds (a puff is 30 seconds interval, that is, puff 2 2 seconds and standby for 28 seconds) A total of 5 suctions were performed. Remove the filter segment from the non-combustion heating smoking article after 5 puffs, and measure its quality. Subtract the mass of the filter segment of the non-combustion heating smoking article before smoking from the aforementioned mass, and calculate the mass increase. For the HCI law, it is the method shown by the Canadian Ministry of Insurance and is recorded in Haelth Canada-Tobacco Reporting Regulation SOR/20000-273. In addition, the reason for the evaluation test by closing the perforation is to exclude the cooling caused by the air introduced from the perforation, and to evaluate the cooling capacity of the filter segment alone. In addition, in the HCI method, the perforation is closed for the absorption system. It is stipulated as one of the conditions.

Figure 1 shows an example of the non-combustion heating smoking article of the present invention. The non-combustion heating smoking article 20 shown in FIG. 1 includes a tobacco-containing section 1 and an interface section 2. The interface section 2 includes a cooling section 3, a center hole section 4, and a filter section 5. When smoking, the tobacco-containing segment 1 is heated, and the end of the filter segment 5 is sucked. In addition, the cooling section 3 and The positions of the central hole section 4 are interchangeable, and the positions of the central hole section 4 and the filter section 5 are also interchangeable. In addition, the interface section 2 may not have the central hole section 4.

The tobacco-containing section 1 has: a tobacco filler 6 containing tobacco and a mist generating substrate, and a cylindrical roll paper 7 covering the tobacco filler 6. The tobacco filler 6 may further contain volatile flavor components and water. There are no particular restrictions on the size of the tobacco used as a filler and its preparation method. For example, the tobacco leaf after drying can be shredded to a width of 0.8 to 1.2 mm. When the cut wire has the aforementioned width, the length of the wire is approximately 5 to 20 mm. In addition, it can also be used: the dried tobacco leaves are crushed to an average particle diameter of about 20 to 200 μm and are homogenized for sheet processing, and the shredded tobacco leaves are cut to a width of 0.8 to 1.2 mm. When the cut wire has the aforementioned width, the length of the wire is approximately 5 to 20 mm. Furthermore, instead of shredding the sheet processed above, those processed by wrinkling may be used as the filler. A plurality of sheets formed into a cylindrical shape may be arranged concentrically. Regardless of whether the dried tobacco leaves are shredded for use, or used as pulverized and homogenized sheets, various types of tobacco contained in the tobacco filler can be used. In order to become the intended fragrance, it can be appropriately blended with yellow species, Burley species, oriental species, existing species, and other Nicotiana Tabacum varieties or Nicotiana Rustica varieties. The details of the aforementioned tobacco varieties are disclosed in "Tobacco History, Tobacco Research Center, 2009.3.31".

There are several previous methods for pulverizing and processing tobacco into uniform flakes. The first type is a sheet made using a papermaking process, and the second type is mixing a suitable solvent such as water and homogenizing, then casting the homogenized thinly on a metal plate or a metal strip and drying it The resulting cast sheet, the third type is to mix in a suitable solvent such as water And the homogenizer is extruded into a thin rolled sheet. The types of the aforementioned homogenized flakes are disclosed in detail in "Tobacco History, Tobacco Research Center, 2009.3.31".

The filling density of the tobacco filler 6 is not particularly limited, but from the viewpoint of ensuring the performance of the non-combustion heating smoking article 20 and imparting a good smoking taste, it is usually 250 mg/cm ³ or more, preferably 320 mg/cm ³ Above, in addition, it is usually 520 mg/cm ³ or less, preferably 420 mg/cm ³ or less. Specifically, in the case of the tobacco-containing section 1 with a circumference of 22mm and a length of 20mm, the content range of the tobacco filler 6 in the tobacco-containing section 1 may be 200 to 450 mg per tobacco-containing section 1 It is preferably 280 to 400 mg.

The mist generating substrate is a material that can generate mist by heating, and is not particularly limited. Examples include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1,3-butane Glycol and so on. These can be used singly or in combination of two or more.

The content of the mist generating substrate in the tobacco filler 6 is not particularly limited. From the viewpoint of sufficient mist generation and good taste, it is usually 5 to 50% by weight, preferably 10 to 20% by weight . In the case where the tobacco filler 6 contains volatile flavor components, the content of the volatile flavor components in the tobacco filler is not particularly limited. From the viewpoint of imparting a good taste, it is usually 10,000 ppm relative to the mass of the tobacco filler Above, it is preferably 20,000 ppm or more, more preferably 25,000 ppm or more, and in addition, it is usually 50,000 ppm or less, preferably 40,000 ppm or less, and particularly preferably 33,000 ppm or less.

The method of filling the tobacco filler 6 in the roll paper 7 is not particularly limited. For example, the tobacco filler 6 can be covered by the roll paper 7, or the tobacco filler 6 can be filled in a cylindrical roll. Paper 7. When the shape of the tobacco has a long side direction like a rectangle, the tobacco can be filled in such a way that the long side direction in the roll paper 7 becomes a non-specific direction, or it becomes the axial direction of the tobacco-containing segment 1 or The way perpendicular to the axial direction is neatly arranged and filled. By heating the tobacco-containing section 1, the tobacco components, the mist generating base material and the water contained in the tobacco filler 6 are vaporized and moved to the interface section 2 by inhalation.

The cooling section 3 is composed of a cylindrical member 8. The cylindrical member 8 may be, for example, a paper tube in which thick paper is processed into a cylindrical shape. In the cylindrical member 8 and the interface paper 15 described later, a perforation 9 can be provided to penetrate both. Due to the existence of the perforation 9, external air is introduced into the cooling section 3 during inhalation. Thereby, the vaporized components of the mist generated by heating the tobacco-containing segment 1 are brought into contact with the outside air, and the temperature is reduced and liquefied to generate mist. The diameter (diameter length) of the perforation 9 is not particularly limited, and may be 0.5 to 1.5 mm, for example. The number of perforations 9 is not particularly limited, and may be one or two or more. For example, multiple perforations 9 can be provided around the cooling section 3. The amount of external air introduced from the perforation 9 is preferably 85% by volume or less, and more preferably 80% by volume or less relative to the total volume of the gas inhaled by the user. By making the ratio of the amount of the aforementioned external air to be 85% by volume or less, it is possible to sufficiently suppress the decrease in the aroma and taste due to the dilution of the external air. From the viewpoint of cooling properties, the lower limit of the range of the ratio of the amount of outside air is preferably 55% by volume or more, and more preferably 60% by volume or more.

5.0至

1.0mm的桿。由於第一填充層10之纖維的填充密度高，所以於吸嚐時空氣或霧氣僅於中空部流動，於第一填充層10內幾乎不流動。由於中心孔節段4內部的第一填充層10為纖維填充層，所以於使用時從外側接觸的觸感帶給使用者之差異感較少。此外，中心孔節段4亦可不具有第一內管捲紙11，而是藉由熱成型來保持該形狀。 The central hole segment is composed of a filling layer with one or more hollow parts and an inner tube roll paper covering the filling layer. For example, the central hole section 4 is composed of a first filling layer 10 having a hollow portion and a first inner tube roll paper 11 covering the first filling layer 10. The central hole section 4 has the function of increasing the strength of the interface section 2. The first filling layer 10 may be configured, for example, to be filled with cellulose acetate fibers at a high density, and 6 to 20% by weight of a plasticizer containing triacetin relative to the mass of the cellulose acetate is added and hardened to form an inner diameter.

5.0 to

1.0mm rod. Due to the high packing density of the fibers of the first packing layer 10, air or mist only flows in the hollow portion during inhalation, and hardly flows in the first packing layer 10. Since the first filling layer 10 inside the central hole section 4 is a fiber filling layer, the tactile touch from the outside during use brings less difference to the user. In addition, the central hole section 4 may not have the first inner tube roll paper 11, but maintain the shape by thermoforming.

The configuration of the filter segment of the present invention is not particularly limited, but for example, the filter segment 5 shown in Figure 1 is composed of a second filling layer 12 and a second inner tube paper roll 13 covering the second filling layer 12 constitute. In the filter segment 5, since the second filling layer 12 exists up to the end, the end has the same appearance as a normal burning smoking article.

The material of the filler in the second filling layer 12 can be appropriately selected so as to increase the aforementioned quality within the scope of the present invention. The material of the aforementioned filler includes, for example, a cellulose acetate fiber bundle to which a plasticizer (triacetin) is added, and paper made of pulp as a main raw material. One type of filler of these materials may be used, or two or more types may be used in combination.

The air permeability resistance of each of the filter segments 5 can be appropriately selected so as to increase the aforementioned mass within the scope of the present invention. When the aforementioned air permeability resistance is high, the filter segment 5 can better capture mist or water vapor, so the aforementioned mass increase will be greater. The air permeability resistance of each of the aforementioned segments is preferably 15 to 60 mmH ₂ O/seg, more preferably 20 to 40 mmH ₂ O/seg, and even more preferably 25 to 30 mmH ₂ O/seg. For example, when the length of the filter segment 5 in the axial direction (the horizontal direction in Figure 1) is 7 mm, the air permeability resistance of each segment is preferably 15 to 60 mmH ₂ O/7 mm. The air permeability resistance of each of the aforementioned segments can be appropriately changed according to the amount and material of the filler filled in the filter segment 5. For example, when the filler is a cellulose acetate fiber bundle, if the amount of the cellulose acetate fiber bundle filled in the filter segment 5 is increased, the air permeability resistance can be increased. When the filler is a cellulose acetate fiber bundle, the packing density of the cellulose acetate fiber bundle may be 0.13 to 0.18 g/cm ³ . In addition, the aforementioned air permeability resistance is a value measured with an air permeability resistance measuring device (trade name: SODIMAX, manufactured by SODIM).

(Measurement of mass increase of filter segment before and after smoking and evaluation of cooling performance)

A filter section that closes the perforated non-combustion heating smoking article provided in the cooling section is connected to the smoking machine through a pipe. In addition, thermocouples are placed before and after the filter segment. The tobacco-containing section of the non-combustion heating smoking article is heated by a heater, and the smoking machine is used for smoking. The heating by the heater is maintained at 230°C for 50 seconds, 200°C for 130 seconds, and then at 170°C. Puffing starts 40 seconds after heating, and according to the HCI Law (Canadian Compulsory Smoking Conditions Act), each puff is set to 55ml/2 seconds (1 puff is a 30-second interval, that is, 2 puffs. Wait for 28 seconds after 2 seconds), and perform 5 suctions in total.

Remove the filter segment from the non-combustion heating smoking article after 5 puffs, and measure its quality. The mass of the filter segment of the non-combustion heating smoking article before smoking is subtracted from the aforementioned mass, and the mass increase of the filter segment before and after smoking is calculated. The results are shown in Table 1.

In order to evaluate the cooling performance, in each suction, the maximum temperature (T _a ) detected by the thermocouple placed before the filter segment is subtracted from the thermoelectric placed after the filter segment. Even the detected maximum temperature (T _b ) is the value ΔT (=T _a -T _b ). The results are shown in Figure 3. Furthermore, Table 1 shows the ΔT of the first puff, that is, the value of ΔT ₁ . In addition, the temperature of the mist temperature of the first suction is the highest, and therefore, it is preferable that ΔT _{1 be} larger.

(Sensory evaluation)

With 4 fully trained testers, the non-combustion heating smoking article with the filter segment with the perforation provided in the cooling segment opened at the same smoking interval as the aforementioned mass increase measurement, and Carry out sensory evaluation (evaluation of smell and sensory temperature). The sensory evaluation was conducted based on the following criteria.

A: Both the aroma and the sensory temperature are suitable for smoking.

B: Although it is suitable for smoking at the sensory temperature, the smell is slightly weak.

C: Although it is suitable for smoking in terms of smell, the sensory temperature is slightly unsuitable.
