Description

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

Ordinary combustible smoking articles (tobacco) that smoke using combustion are made of dried tobacco leaves carved to a width of about 1 mm, and a paper filling with a fragrance, a moisturizer, and an appropriate amount of water added. It has a tobacco-containing segment wrapped in a columnar shape with a wrapper made of paper, and a mouthpiece segment made of fibers made of cellulose acetate or the like or pleated paper wrapped in a columnar shape with a paper wrapper. The tobacco-containing segment and the mouthpiece segment are connected by a lining paper. Smoking is performed by a smoker igniting the end of the tobacco-containing segment with a lighter or the like and sucking from the end of the mouthpiece segment. The tip of the tobacco-containing segment burns at a temperature exceeding 800 ° C.

As an alternative to such ordinary combustion smoking articles, non-combustion heating smoking articles and non-combustion heating smoking systems that utilize heating instead of combustion have been developed (for example, Patent Documents 1 to 6). The heating temperature is lower than the combustion temperature of the burning smoking article, for example, 400 ° C. or lower. In non-combustion heated smoking articles, the tobacco filling of the tobacco-containing segment contains an aerosol-forming substrate such as glycerin, propylene glycol (PG), triethylcitrate (TEC), triacetin. The aerosol-forming substrate is vaporized by heating and transferred by suction to the cooling segment within the mouthpiece segment, where it is cooled to further ensure aerosol formation. When suction is performed from the filter segment provided at the end on the mouthpiece side in the mouthpiece segment, the aerosol is also sucked together, so that the smoker's satisfaction can be ensured.

A non-combustion-heated smoking system generally comprises a columnar non-combustion-heated 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, and the like. Examples of the heater include a heater by electric resistance and a heater by IH. As a method of heating the heater by electric resistance, a method of heating with a heater from the outside of the non-combustion heated smoking article, or a needle-shaped or blade-shaped heater is placed in the tobacco-containing segment containing the tobacco filling from the tip of the non-combustion heated smoking article. Examples thereof include a method of inserting and heating.

As described above, the aerosol-forming substrate (hereinafter, also referred to as an aerosol vaporization component) vaporized by heating is mainly cooled in the cooling segment, and condensation occurs from vapor to particles to become an aerosol. Here, the aerosol vaporization component is required to be sufficiently cooled so that the smoker can suck it from the filter segment provided at the end on the mouthpiece side. As a cooling segment for non-combustion heating smoking articles, for example, in Patent Document 4, a perforation is provided on the outer periphery of a cylindrical portion of a cavity, outside air is introduced from the perforation at the time of suction, and the aerosol vaporization component and the outside air are brought into contact with each other for cooling. The configuration is disclosed.

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

The content of the aerosol-forming base material in the tobacco filling 6 is not particularly limited, and is usually 5 to 50% by mass, preferably 10 to 10% by mass, from the viewpoint of sufficiently producing an aerosol and imparting a good taste. It is 20% by mass. When the tobacco filling 6 contains a volatile flavor component, the content of the volatile flavor component in the tobacco filling is not particularly limited, and from the viewpoint of imparting a good taste, 10000 ppm with respect to the amount of the usual tobacco filling substance. It is more than that, preferably 20000 ppm or more, more preferably 25000 ppm or more, and usually 50,000 ppm or less, preferably 40,000 ppm or less, and more preferably 33000 ppm or less.

The method of filling the tobacco filling 6 in the wrapper 7 is not particularly limited. For example, the tobacco filling 6 may be wrapped in the wrapper 7, or the tubular wrapper 7 may be filled with the tobacco filling 6. When the shape of the tobacco has a longitudinal direction such as a rectangular shape, the tobacco may be filled so that the longitudinal direction is an unspecified direction in the wrapper 7, and the tobacco-containing segment 1 may be filled in the axial direction or the tobacco-containing segment 1. The tobacco may be aligned and filled so as to be perpendicular to the axial direction. When the tobacco-containing segment 1 is heated, the tobacco component, aerosol-forming base material and water contained in the tobacco filling 6 are vaporized, and these are transferred to the mouthpiece segment 2 by suction.

The cooling segment 3 is composed of a tubular member 8. The tubular member 8 can be, for example, a paper tube obtained by processing thick paper into a cylindrical shape. The tubular member 8 and the mouthpiece lining paper 15, which will be described later, are provided with a perforation 9 penetrating both of them. The perforations 9 introduce air into the cooling segment 3 from the outside during suction. As a result, the aerosol vaporization component generated by heating the tobacco-containing segment 1 comes into contact with the outside air, and the temperature drops, so that the aerosol is liquefied to form an aerosol. The diameter (crossing length) of the perforation 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 periphery of the cooling segment 3. The amount of outside air introduced from the perforation 9 is preferably 85% by volume or less, more preferably 80% by volume or less, based on the total volume of the gas sucked 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 in this range, it is possible to sufficiently suppress the reduction of flavor and taste due to dilution by the outside air.

The center hole segment is composed of a packed layer having a hollow portion and an inner plug wrapper covering the packed 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 that covers the first filling layer 10. The center hole segment 4 also has a function of increasing the strength of the mouthpiece segment 2. The first packed bed 10 may be, for example, a hollow rod packed with cellulose acetate fibers at a high density and hardened by adding 6 to 20% by mass of a plasticizer containing triacetin to the mass of cellulose acetate. can. Since the first packed layer 10 has a high fiber filling density, air and aerosol flow only in the hollow portion at the time of suction, and hardly flow in the first packed layer 10. 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 is less likely to cause discomfort to the smoker. The center hole segment 4 is preferably 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.

The configuration of the filter segment in the present invention is not particularly limited, but as shown in the filter segment 5 of FIG. 2, for example, the second packing layer 12 and the second inner plug wrapper 13 covering the second packing layer 12 (FIG. 1). 5in) and an outer plug wrapper 14 (5out in FIG. 1) covering the outer plug wrapper 14 (5in). Since the second filling layer 12 exists up to the end of the mouthpiece in 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, the heat insulating property is good, and the smoker feels a temperature suitable for smoking on the lips when smoking. From this point of view, it is preferable that both the inner plug wrapper and the outer plug wrapper are made of the paper. The basis weight is more preferably 60 g / m ² or more, and the upper limit thereof is not limited, but is preferably 150 g / m ² or less, and more preferably 130 g / m ² or less. The thickness is more preferably 110 μm or more, and the upper limit thereof is not limited, but is preferably 150 μm or less, and more preferably 130 μm or less. When the basis weight and the thickness are in this range, the non-combustion heated smoking article can be easily manufactured. 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 the filter segment 5 may be connected by one outer plug wrapper 14.

The peripheral length of the filter segment 5 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and 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 shape of the cross section of the filter segment 5 is not particularly limited, but may be, for example, a circular shape, an elliptical shape, a polygonal shape, or the like.

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

The axial length of the non-combustion heated smoking article according to the present invention, that is, the length in the horizontal direction in FIG. 2 is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and more preferably 50 mm to 60 mm. Is more preferable. 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 even more 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 1 can be selected within the range of 4 to 10 mm, and the ventilation resistance of the filter segment 1 at that time is selected so as to be _{15 to 60 mmH 2 O / seg per segment.} The length of each of these individual segments can be appropriately changed according to manufacturing suitability, required quality, and the like. Furthermore, even if only the filter segment is arranged on the downstream side of the cooling segment without using the center hole segment, it can function as a non-combustion heated smoking article.
