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

Common burning smoking articles (cigarettes) that use burning to smoke have: a paper roll will add fragrance, moisturizer and moderate to the dried leaves of tobacco (also called tobacco) cut to a width of about 1 mm Tobacco fillers containing moisture, etc., are rolled into cylindrical tobacco-containing segments, and fibers made of cellulose acetate, etc., or pleated paper rolled into cylindrical joints by paper rolls Segments. 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), and triethyl citrate (TEC: Triethyl Citrate), glycerol triacetate and other mist (aerosol, also known as aerosol) generate 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.

[Non-combustion heating smoking articles]

The non-combustion heating smoking article of the present invention is provided with: a tobacco-containing section containing tobacco and a mist generating substrate; a cylindrical cooling section with perforations on the periphery; and a cylinder having an inner diameter smaller than the cooling section A member; wherein the end of the cooling section in the suction direction is joined to the member, and the perforation is provided at a position 2 to 4 mm from the joint surface. The distance is the distance between the center of the perforation and the joint surface. Figure 1 shows the outline of the present invention. In Figure 1, 1 is a tobacco-containing section, 3 is a cooling section, 4 is a cylindrical member with an inner diameter smaller than that of the cooling section, 9 is a perforation, and O is the joint surface of the cooling section 3 and the member 4. , T is the distance between the joint surface O and the center of the perforation. The vaporized components of the mist generated in the tobacco-containing section 1 are cooled in the cooling section 3 and become mist, and are introduced into the component 4. At this time, the mist is mixed with the air introduced from the perforation 9 to be further cooled. Because the inner diameter is downstream from the joint surface O toward the suction port (in order to Below, also referred to as "downstream") sharply shrinks, thus causing the flow of the mixed flow of mist and air (hereinafter, also referred to as "mixed flow") to change. In the present invention, the through hole 9 is provided at a specific position from the joint surface O. The perforation 9 can improve the mixing efficiency of the mist and the aforementioned air. From such a viewpoint, the upper limit of t is 4 mm or less. On the other hand, if the perforation 9 is too close to the joint surface O, the strength of the non-combustion heating smoking article will decrease. From such a viewpoint, the lower limit of t is 2 mm or more. Therefore, t is in the aforementioned range, whereby the balance between cooling efficiency and strength can be optimized. Furthermore, in the present invention, since there is no need to introduce a large amount of air from the perforation 9 excessively, the effect of effectively cooling the mist without reducing the aroma and odor is achieved. From such a viewpoint, t is preferably 2.5 to 3.5 mm.

From the viewpoint of rapidly changing the flow of the mixed flow from the boundary of the joint surface O, when the inner diameter of the member 4 is set to d and the inner diameter of the cooling section 3 is set to D, d/D is optimally 0.4 to 0.7 , Particularly preferably 0.5 to 0.7. If d/D is in this range, it is possible to change the flow of the mixed flow from laminar flow to turbulent flow (turbulent flow) starting from the border of the joint surface O. The inner diameter d is not limited, but it is usually preferably 2.8 to 4.8 mm.

In the non-combustion heating smoking article of the present invention, other members such as a filter segment may be provided downstream of the member 4. Therefore, the distance from the suction port end to the center of the perforation 9 will vary depending on the size of the component arranged downstream, but in one aspect, the distance is preferably 17 to 19 mm.

The component 4 is preferably a central hole segment, and the downstream of the component 4 is preferably a filter segment. Figure 2 shows a preferred aspect of the non-combustion heating smoking article of the present invention.

In Figure 2, 20 is a non-combustion heating smoking article, 1 is a tobacco-containing section, and 2 is an interface section. The interface section 2 is equipped with: cooling section 3; center hole section as the aforementioned component Section 4'; and filter section 5. When smoking, the tobacco-containing segment 1 is heated, and the end of the filter segment 5 is sucked.

The tobacco-containing segment 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 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 cylindrical sheets 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".

Regarding the method of crushing and processing tobacco into uniform flakes, there are a plurality of previous methods. 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 third type of cast sheet is mixed with water, etc. It is extruded into a thin rolled sheet after homogenization. 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 can be set to be 200 to 450 mg per tobacco-containing section 1 It is preferably 280 to 400 mg.

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 into the roll paper 7 is not particularly limited. For example, the tobacco filler 6 may be covered by the roll paper 7, or the tobacco filler 6 may be filled in a cylindrical shape. Roll of 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 non-specific directions, or it can also be 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. Through 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 section 1 are brought into contact with external air, and the temperature is reduced and liquefied to form 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, more preferably 80% by volume or less; preferably 55% by volume or more, particularly preferably 60% by volume relative to the total volume of the gas inhaled by the user Above volume %. The ratio of the aforementioned amount of external air is within this range, thereby sufficiently suppressing the decrease in aroma and odor caused by the dilution of external air.

The central hole segment is composed of a filling layer with a hollow part 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. For example, the first filling layer 10 may be configured 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 a hollow的杆体。 Body. Due to the fiber of the first filling layer 10 The packing density is high, so air or mist only flows in the hollow part during inhalation, and hardly flows in the first packing layer 10. Since the first filling layer 10 inside the central hole segment 4'is a fiber filling layer, the tactile touch from the outside during use brings less difference to the user. The central hole section 4'is preferably further wrapped with an outer tube roll paper 14. As shown in Figure 2, the outer tube roll paper 14 can also be wound with the central hole section 4'and the filter section 5 at the same time.

The configuration of the filter segment of the present invention is not particularly limited. For example, the filter segment 5 in FIG. 2 is composed of a second packing layer 12 and a second inner tube paper roll 13 covering the second packing layer 12. In the filter segment 5, since the second filling layer 12 exists up to the end of the mouthpiece, this end has the same appearance as a normal burning smoking article. At least one of the inner tube roll paper 13 or the outer tube roll paper 14 is preferably paper having a basis weight of 40 g/m ² or more and a thickness of 100 μm or more. Such paper has a relatively large weight per unit area and is relatively thick, so the heat insulation becomes good, and when smoking, the lips of the smoker can feel the temperature suitable for smoking. From such a viewpoint, it is preferable that both the inner tube roll paper and the outer tube roll paper are composed of the paper. The weight per unit area is particularly preferably 60 g/m ² or more, and the upper limit is not limited, and it is preferably 150 g/m ² or less, and particularly preferably 130 g/m ² or less. The thickness is particularly preferably 110 μm or more, and the upper limit is not limited, and it is preferably 150 μm or less, and particularly preferably 130 μm or less. If the weight per unit area and the thickness are within this range, the production of non-combustion heating smoking articles also becomes easy. In order to further improve the heat insulation efficiency, it is preferable that one or both of the inner tube roll paper 11 or the outer tube roll paper 14 constituting the central hole segment 4'is formed of the aforementioned paper. The central hole section 4'and the filter section 5 can also be connected by a sheet of outer tube roll paper 14.

The length around the filter segment 5 is not particularly limited, and is preferably 16 to 25 mm, particularly preferably 20 to 24 mm, and more preferably 21 to 23 mm. The length of the filter segment 5 in the axial direction (the horizontal direction in FIG. 2) is not particularly limited, and is preferably 3 to 15 mm, and particularly preferably 5 to 10mm. The cross-sectional shape of the filter segment 5 is not particularly limited, and may be, for example, a circle, an ellipse, a polygon, or the like.

As mentioned above, the central hole section 4'and the filter section 5 can also be connected by a sheet of outer tube roll paper 14. The tobacco-containing section 1 and the cooling section 3 are connected with the connected central hole section 4'and the filter section 5 by an interface paper 15. For these connections, for example, glue such as vinyl acetate-based glue can be applied to the inner surface of the interface liner 15, and the aforementioned three segments can be loaded and then rolled to connect.

[Example]

[Examples 1 to 3]

As shown in Figure 2, a non-combustion heating smoking article with a total length of 55 mm formed by joining the tobacco section, the cooling section, the center hole section, and the filter section is prepared as shown in Figure 2. And in the first table shows the size of each segment.

[Table 1]

On the outer periphery of the cooling section, fifteen perforations are continuously arranged in a circle around the periphery. Perforations are arranged at equal intervals so that Vf is about 70% by volume. The so-called Vf is defined by: the amount of outside air introduced from the perforation 9/the overall amount of gas inhaled by the user. The distance from the joint surface of the cooling section and the central hole section to the perforation is set to 2 to 4 mm.

The filter segment of the non-combustion heating smoking article is connected to the smoking machine through a pipe. In addition, a thermocouple was inserted from the outer periphery of the tube, and the tip of the thermocouple was arranged 5 mm from the mouth end and on the central axis of the non-combustion heating smoking article. 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. Inhalation is based on the CIR Law (Canadian Compulsory Smoking Condition Act), each puff is set to 55ml/2 seconds (1 puff is a 30-second interval, that is, wait for 28 seconds after inhaling for 2 seconds), for a total of 5 Puffs. Record the maximum temperature among the temperatures of each suction as the packaging paper temperature (tipping paper temperature). The results are shown in Table 2.
