Description

The present invention relates to non-combustion heating smoking articles and non-combustion heating smoking systems.

Ordinary combustible smoking articles (tobacco) that use combustion to smoke are made by adding tobacco fillers, such as flavoring agents, moisturizing agents, and moderate moisture, to dried tobacco leaves that are chopped to a width of about 1 mm. A tobacco-containing segment cylindrically wrapped with a wrapper made of cellulose acetate or the like, and a mouthpiece segment cylindrically wrapped with a paper wrapper made of fiber or pleated paper made of cellulose acetate or the like. The tobacco-containing segment and the mouthpiece segment are connected by lining paper. A smoker ignites the end of the tobacco-containing segment with a lighter or the like, and smokes by inhaling from the end of the mouthpiece segment. The tobacco-containing segment tips burn at temperatures above 800°C.

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 (eg, US Pat. The heating temperature is lower than the combustion temperature in the combustion smoking article, for example below 400°C. In non-combustion heated smoking articles, the tobacco filler of the tobacco-containing segment comprises an aerosol-generating substrate such as glycerin, propylene glycol (PG), triethylcitrate (TEC), triacetin, and the like. The aerosol-generating substrate is vaporized by heating, moved by suction to a cooling segment within the mouthpiece segment, and cooled to further ensure aerosol generation. When inhaling from the filter segment provided at the mouthpiece-side end of the mouthpiece segment, the aerosol is also inhaled, so that the smoker's satisfaction can be ensured.

A non-combustion heating smoking system generally comprises a cylindrical non-combustion heating smoking article having a shape similar to a conventional combustion smoking article, and a heating device including a battery, controller, heater, or the like. The heater may be a heater by electrical resistance or a heater by IH. Heating methods using electrical resistance include a method in which a heater is used to heat the non-combustion heating smoking article from the outside, and a needle-shaped or blade-shaped heater is placed from the tip of the non-combustion heating smoking article into the tobacco-containing segment containing the tobacco filler. The method of inserting and heating, etc. are mentioned.

Patent No. 5292410 Patent No. 5771338 Japanese Patent Publication No. 2013-507906 WO2017/198838 Patent No. 5877618 Japanese Patent Publication No. 2016-506729

As described above, the aerosol-generating substrate vaporized by heating (hereinafter also referred to as the aerosol vaporization component) is mainly cooled in the cooling segment to cause condensation of the vapor into particles to form an aerosol. Here, the aerosol vaporization component is required to be sufficiently cooled so that the smoker can inhale through the filter segment provided at the end on the mouthpiece side. As a cooling segment for a non-combustible heating smoking article, for example, Patent Document 4 discloses that perforations are provided on the outer periphery of a hollow cylindrical portion, and outside air is introduced through the perforations at the time of inhalation, and the aerosol vaporized component and the outside air are brought into contact with each other for cooling. A configuration is disclosed.

By the way, smokers also perceive heat on their lips when smoking. That is, even if the temperature of the aerosol vaporization component is lowered by cooling, if the temperature is transferred to the lips at the mouthpiece, the smoker will feel uncomfortable. Therefore, in order to obtain a satisfying smoking experience, the smoker needs to feel an appropriate smoking temperature on his/her lips. In view of such circumstances, the object of the present invention is to provide a non-combustion heating smoking article that allows a smoker to feel a temperature suitable for smoking on their lips when smoking, and a non-combustion heating smoking system comprising the non-combustion heating smoking article. .

The tobacco-containing segment 1 has a tobacco filling 6 containing tobacco and an aerosol-generating substrate, and a tubular wrapper 7 covering the tobacco filling 6 . Tobacco filling 6 may further contain volatile flavor components and water. There are no restrictions on the size of the tobacco used as the filling or the preparation method thereof. For example, dried tobacco leaves chopped into widths of 0.8 to 1.2 mm may be used. When it is chopped to the above width, the chopped length is about 5 to 20 mm. Alternatively, dried tobacco leaves may be pulverized to have an average particle diameter of about 20 to 200 μm, homogenized, processed into sheets, and cut into pieces having a width of 0.8 to 1.2 mm. . When it is chopped to the above width, the length of the chop is about 5 to 20 mm. Furthermore, the above-mentioned sheet-processed material may be gathered without being chopped and used as the filling material. Also, a plurality of cylindrical sheets may be arranged concentrically. Whether the dried tobacco leaves are chopped and used, or the tobacco is pulverized and used as a homogenized sheet, various types of tobacco can be used in the tobacco filling. Yellow variety, burley variety, orient variety, native variety, and other Nicotiana tabacum and Nicotiana rustica varieties can be blended as appropriate to obtain the desired taste. Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Research Center, March 31, 2009".

There are several conventional methods for pulverizing tobacco into homogenized sheets. One is a paper-making sheet made using a papermaking process, and the other is a homogenized product mixed with an appropriate solvent such as water, then thinly cast on a metal plate or a metal plate belt, and dried. The third is a rolled sheet obtained by mixing an appropriate solvent such as water and homogenizing it and extruding it into a sheet. The types of the homogenizing sheet are disclosed in detail in "Encyclopedia of Tobacco, Tobacco Research Center, March 31, 2009".

Moreover, these volatile fragrance components may be used alone or in combination of two or more.

The content of the aerosol-generating base material in the tobacco filling 6 is not particularly limited, and is usually 5 to 50% by mass, preferably 10 to 50% by mass, from the viewpoint of sufficiently generating an aerosol and imparting a good smoking taste. 20% by mass. When the tobacco filling 6 contains a volatile flavoring component, the content of the volatile flavoring component in the tobacco filling is not particularly limited, and from the viewpoint of imparting a good smoking taste, it is usually 10000 ppm relative to the amount of the tobacco filling substance. above, preferably 20000 ppm or more, more preferably 25000 ppm or more, and usually 50000 ppm or less, preferably 40000 ppm or less, more preferably 33000 ppm or less.

The method of filling the tobacco filling 6 into the wrapper 7 is not particularly limited, but for example, the tobacco filling 6 may be wrapped in the wrapper 7 or the tobacco filling 6 may be filled in the cylindrical wrapper 7 . When the shape of the tobacco has a longitudinal direction such as a rectangular shape, the tobacco may be packed so that the longitudinal direction is in an unspecified direction within the wrapper 7, and may be in the axial direction of the tobacco-containing segment 1 or in the longitudinal direction. They may be aligned and filled 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 filling 6 are vaporized and transferred to the mouthpiece segment 2 by suction.

The cooling segment 3 is composed of a tubular member 8 . The cylindrical member 8 can be a paper tube formed by processing cardboard into a cylindrical shape, for example. The tubular member 8 and a mouthpiece lining paper 15, which will be described later, are provided with perforations 9 penetrating both. Through the perforations 9 air is introduced into the cooling segment 3 from the outside during suction. As a result, the vaporized aerosol component generated by heating the tobacco-containing segment 1 comes into contact with the outside air and liquefies due to the decrease in temperature to form an aerosol. The diameter (spanning length) of the perforations 9 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 9 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 9 may be provided on the circumference of the cooling segment 3 . The amount of outside air introduced through the perforations 9 is preferably 85% by volume or less, more preferably 80% by volume or less, relative to the total volume of the gas inhaled by the smoker. The lower limit is preferably 55% by volume or more, more preferably 60% by volume or more. When the ratio of the amount of outside air is within this range, it is possible to sufficiently suppress reduction in flavor and taste due to dilution by outside air.

The center hole segment is composed of a filling layer having a hollow portion and an inner plug wrapper 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 plug wrapper 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 can be, for example, a hollow rod filled with cellulose acetate fibers at a high density and hardened by adding a plasticizer containing triacetin in an amount of 6 to 20% by mass based on the mass of cellulose acetate. can. Since the first packed layer 10 has a high packing density of fibers, air and aerosol flow only in the hollow portion and hardly flow in the first packed layer 10 during suction. Since the first filling layer 10 inside the center hole segment 4 is a fiber filling layer, the feeling of touch from the outside during use hardly causes a smoker to feel uncomfortable. Preferably, the center hole segment 4 is further wrapped with an outer plug wrapper 14 . As shown in FIG. 2, the outer plug wrapper 14 may wind the center hole segment 4 and the filter segment 5 at the same time.

Although the configuration of the filter segment in the present invention is not particularly limited, for example, like the filter segment 5 in FIG. 5in) and an outer plug wrapper 14 (5out in FIG. 1) covering this. Due to the presence of the second fill layer 12 up to the tip end of the filter segment 5, the end has an appearance similar to that of a normal combustion smoking article.

At least one of the inner plug wrapper 13 and the outer plug wrapper 14 is paper having a basis weight of 40 g/m ² or more and a thickness of 100 μm or more. Since such paper has a relatively large basis weight and is thick, it has good heat insulating properties, and when smoking, the smoker feels a temperature suitable for smoking on his/her lips. From this point of view, both the inner plug wrapper and the outer plug wrapper are preferably made of the paper. The basis weight is more preferably 60 g/m ² or more, and although the upper limit is not limited, it is preferably 150 g/m ² or less, more preferably 130 g/m ² or less. The thickness is more preferably 110 μm or more, and although the upper limit is not limited, it is preferably 150 μm or less, more preferably 130 μm or less. This range of basis weight and thickness also facilitates the manufacture of non-combustion heated smoking articles. In order to further improve the heat insulation efficiency, it is preferable that one or both of the inner plug wrapper 11 and the outer plug wrapper 14 constituting the center hole segment 4 are also made of the paper. The center hole segment 4 and filter segment 5 may be connected by one outer plug wrapper 14 .

Although the length of the circumference of the filter segment 5 is not particularly limited, it is preferably 16 to 25 mm, more preferably 20 to 24 mm, even more preferably 21 to 23 mm. The length of the filter segment 5 in the axial direction (horizontal direction in FIG. 2) is not particularly limited, but is preferably 3 to 15 mm, more preferably 5 to 10 mm. The cross-sectional shape of the filter segment 5 is not particularly limited, but may be, for example, circular, elliptical, or polygonal.

The tobacco-containing segment 1 , cooling segment 3 , connected center hole segment 4 and filter segment 5 are connected by mouthpiece lining paper 15 . These connections can be made, for example, by applying glue such as vinyl acetate glue to the inner surface of the mouthpiece lining paper 15, inserting the three segments, and winding them.

The length of the non-combustion heating smoking article according to the present invention in the axial direction, that is, the horizontal direction in FIG. is more preferable. In addition, the circumference of the non-combustion heating smoking article is preferably 16 mm to 25 mm, more preferably 20 mm to 24 mm, even more preferably 21 mm to 23 mm. For example, the tobacco-containing segment 1 has a length of 20 mm, the cooling segment 3 has a length of 20 mm, the center hole segment 4 has a length of 8 mm, and the filter segment 5 has a length of 7 mm. The length of the filter segment 5 can be selected within the range of 4-10 mm, and the ventilation resistance of the filter segment 5 is selected to be 15-60 mmH ₂ O/seg per segment. These individual segment lengths can be changed as appropriate according to manufacturability, required quality, and the like. Furthermore, even if only the filter segment is arranged downstream of the cooling segment without using the center hole segment, it is also possible to function as a non-combustion heated smoking article.
