Description

Non-combustion heated smoking article and non-combustion heated smoking system

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

A normal burning smoking article (cigarette) that smokes by using combustion is made of paper with a tobacco filler made by adding a flavoring agent, a moisturizing agent, and an appropriate amount of water to dry tobacco leaf carved into a width of about 1 mm The cigarette-containing segment is wound into a cylindrical shape with a wrapper made of paper, and the mouthpiece segment is obtained by winding a fiber or pleated paper made of cellulose acetate or the like into a cylindrical shape with a paper wrapper. The tobacco-containing segment and the mouthpiece segment are connected by a lining paper. Smoking is performed by the 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 tobacco-containing segment tip burns at a temperature above 800 ° C.

As a substitute for such ordinary burning smoking articles, non-burning heating smoking articles and non-burning heating smoking systems that utilize heating instead of burning have been developed (for example, Patent Documents 1 to 6). The heating temperature is lower than the combustion temperature in the burning smoking article, for example, it is heated at 400 ° C. or lower. In non-combustion heated smoking articles, the tobacco fill of the tobacco-containing segment comprises an aerosol-forming substrate such as glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin. The aerosol-generating substrate is vaporized by heating and moved by suction to a cooling segment in the mouthpiece segment, where it is cooled to more reliably produce an aerosol. When performing inhalation from the filter segment provided at the mouth end side end portion in the mouthpiece segment, the aerosol is also inhaled, so that the smoker's satisfaction can be secured.

The non-combustion heating smoking system generally includes 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, and the like. Examples of the heater include a heater based on electric resistance and a heater based on 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 heating smoking article, a needle-like or blade-shaped heater from the tip of the non-combustion heating smoking article into a tobacco-containing segment containing a tobacco filler. Examples include a method of inserting and heating.

Moreover, these volatile fragrance | flavor components may be used individually by 1 type or in combination of 2 or more types.

The content of the aerosol-generating base material in the tobacco filler 6 is not particularly limited, and is usually 5 to 50% by mass, and preferably 10 to 10% from the viewpoint of sufficiently generating the aerosol and imparting a good taste. It is 20% by mass. When the tobacco filler 6 contains a volatile flavor component, the content of the volatile flavor component in the tobacco filler is not particularly limited, and is usually 10000 ppm with respect to the amount of the tobacco filler, from the viewpoint of imparting a good taste. Or more, preferably 20,000 ppm or more, more preferably 25,000 ppm or more, and usually 50,000 ppm or less, preferably 40,000 ppm or less, more preferably 33,000 ppm or less.

The method for filling the tobacco filling 6 into the wrapper 7 is not particularly limited, but for example, the tobacco filling 6 may be wrapped with the wrapper 7, or the tubular wrapper 7 may be filled with the tobacco filling 6. When the shape of the cigarette has a longitudinal direction such as a rectangular shape, the tobacco may be filled so that the longitudinal direction is in an unspecified direction in the wrapper 7, and the tobacco is contained in the axial direction of the tobacco-containing segment 1 or It may be filled with being aligned so as to be a direction perpendicular to the axial direction. By heating the tobacco-containing segment 1, the tobacco component, the aerosol-forming base material and the 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 cardboard into a cylindrical shape. The tubular member 8 and the mouthpiece lining paper 15 described below are provided with perforations 9 penetrating both. The perforations 9 allow air to be introduced into the cooling segment 3 from the outside during suction. As a result, the aerosol-vaporized component generated by heating the tobacco-containing segment 1 comes into contact with the outside air, and its temperature lowers, so that it is liquefied and an aerosol is formed. The diameter (passage 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, and more preferably 80% by volume or less with respect to 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 the outside air is within this range, it is possible to sufficiently suppress the reduction of the flavor and taste due to the dilution with the 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 includes 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 filling layer 10 may be, for example, a hollow rod in which cellulose acetate fibers are filled at a high density and a plasticizer containing triacetin is added in an amount of 6 to 20% by mass based on the mass of cellulose acetate and cured. it can. Since the first packed bed 10 has a high fiber packing density, air and aerosol flow only through the hollow portion during suction, and hardly flow inside the first packed bed 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 rarely gives a smoker a feeling of strangeness. The center hole segment 4 is preferably further wound 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 structure of the filter segment in the present invention is not particularly limited, but as in the filter segment 5 of FIG. 2, for example, the second filling layer 12 and the second inner plug wrapper 13 that covers the second filling layer 12 (see FIG. 1). 5 in) and an outer plug wrapper 14 (5 out in FIG. 1) covering the same. In the filter segment 5, the second packing layer 12 exists up to the end of the mouthpiece, so that the end has an appearance similar to that of a normal burning 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 a paper has a relatively large and thick basis weight, it has a good heat insulating property, and the smoker feels a temperature suitable for smoking on the lips during smoking. From this viewpoint, 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 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 the upper limit thereof is not limited, but preferably 150 μm or less, more preferably 130 μm or less. When the basis weight and the thickness are within this range, it is easy to manufacture a non-combustion heated smoking article. In order to further improve the heat insulating efficiency, it is preferable that one or both of the inner plug wrapper 11 and the outer plug wrapper 14 that form 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 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. 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 circle, an ellipse, a polygon, 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 an adhesive such as vinyl acetate adhesive on the inner surface of the mouthpiece lining paper 15, and inserting and winding the three segments.

The length of the non-combustion heated smoking article according to the present invention in the axial direction, that is, 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 peripheral length 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 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 1 can be selected in the range of 4 to 10 mm, and the ventilation resistance of the filter segment 1 is selected to be 15 to 60 mmH ₂ O / seg per segment. The length of each of these segments can be appropriately changed depending on the manufacturing suitability, the required quality, and the like. Furthermore, it is also possible to function as a non-combustion heated smoking article by disposing only the filter segment on the downstream side of the cooling segment without using the center hole segment.
