Description

Non-combustion heated tobacco and electric heated tobacco products

This disclosure relates to non-combustion heated tobacco and electrically heated tobacco products.

In recent years, as an alternative to cigarettes (cigarettes), non-combustion heat-not-burn tobacco that is used by inserting it into an electrically heated device has been developed (Patent Document 1). The non-combustion heat-not-burn tobacco generally includes a tobacco rod in which a material for producing tobacco nicks and flavor components is wrapped with rolling paper, a mouthpiece for sucking components generated from the tobacco rod by heating, and these. Equipped with a tip paper to wrap.
Generally, in an electrically heated tobacco product, a non-combustion heated tobacco is inserted into an electrically heated device, and then the heater member is heated to heat the tobacco rod starting from a point in contact with the heater member. The generated ingredients are delivered to the user.

For non-combustion heat-not-burn tobacco, fragrance may be added to the tobacco rod for the purpose of adding fragrance to the mainstream smoke. When producing such non-combustion heat-not-burn tobacco, a method of adding a fragrance solution to dried tobacco leaves is generally adopted. This method has an advantage that the perfume can be easily added to the dried tobacco leaves by spraying the perfume solution.

Japanese Patent Publication No. 2015-508676

However, in the conventional non-combustion type heated tobacco, an excessive amount of fragrance is released in the early stage of smoking, and the amount of fragrance released decreases rapidly as the puff progresses, so that the flavor is stable from the early stage to the late stage of smoking. However, there remains the problem that the flavor of the late smoking period deteriorates.

<Non-combustion heating type cigarette>
The non-combustion heat-not-burn tobacco (also simply referred to as "non-combustion heat-not-burn tobacco") according to an embodiment of the present invention is a rod-shaped non-combustion heat-not-burn tobacco provided with a tobacco rod portion and a mouthpiece portion. The mouthpiece portion includes a cooling segment and a filter segment containing a filter filter medium, and the cooling segment and the filter segment are adjacent to each other, and the tobacco rod portion includes dried tobacco leaves (dried tobacco leaves). A non-combustion heat-not-burn tobacco that contains a fragrance-containing material in which a fragrance is contained in a gel of polysaccharides.
A suitable example of the non-combustion heat-not-burn tobacco according to the present embodiment will be described with reference to FIG.

The non-combustion heat-not-burn tobacco 10 shown in FIG. 1 is a rod-shaped non-combustion heat-not-burn tobacco having a tobacco rod portion 11, a mouthpiece portion 14, and a chip paper 15 wrapped around these, and the mouthpiece. The unit 14 includes a cooling segment 12 and a filter segment 13 including a filter filter medium, and the cooling segment 12 is the tobacco with respect to the axial direction (also referred to as “long axis direction”) of the non-combustion heat-not-burn tobacco 10. The rod portion 11 and the filter segment 13 may be sandwiched adjacent to each other, and holes V may be provided concentrically in the circumferential direction of the cooling segment 12.

The opening V provided in the cooling segment 12 of the non-combustion heat-not-burn tobacco 10 shown in FIG. 1 is usually a hole for promoting the inflow of air from the outside due to the suction of the user, and the inflow of the air causes the inflow of tobacco. The temperature of the components and air flowing in from the rod portion 11 can be lowered.
The opening V that may be provided in the present embodiment may be described as being present in a region of 4 mm or more in the direction toward the cooling segment from the boundary between the cooling segment 12 and the filter segment 13. With this configuration, it is possible to improve the cooling capacity for lowering the temperature of the components and air generated by heating, and further suppress the retention of the components and air in the cooling segment, which in turn suppresses the delivery of the components. The amount can be improved.
Examples of the component produced by heating include a flavor component derived from a fragrance; nicotine and tar derived from tobacco leaves; an aerosol component derived from an aerosol base material; and the like. In the present specification, the aerosol base material is a base material for producing an aerosol.

The rod-shaped non-combustion heat-not-burn tobacco 10 preferably has a columnar shape satisfying a shape having an aspect ratio of 1 or more as defined below.
Aspect ratio = h / w
w is the width of the bottom surface of the columnar body (in the present specification, the width of the bottom surface on the tobacco rod portion side), h is the height of the columnar body, and h ≧ w is preferable. In the present specification, the long axis direction is defined as the direction indicated by h. Therefore, even if w ≧ h, the direction indicated by h is referred to as the major axis direction for convenience. The shape of the bottom surface is not limited and may be a polygon, a polygon with rounded corners, a circle, an ellipse, or the like, and the width w is a diameter when the bottom surface is circular, a major axis when the bottom surface is elliptical, or a polygon or rounded corners. If it is a polygon, it is the diameter of the circumscribed circle or the major axis of the circumscribed ellipse.
The length h in the major axis direction of the non-combustion heat-not-burn tobacco 10 is not particularly limited, and is, for example, usually 40 mm or more, preferably 45 mm or more, more preferably 50 mm or more, and usually 100 mm. It is less than or equal to, preferably 90 mm or less, and more preferably 80 mm or less.
The width w of the bottom surface of the columnar body of the non-combustion heat-not-burn tobacco 10 is not particularly limited, and is, for example, usually 5 mm or more, preferably 5.5 mm or more, and usually 10 mm or less, 9 mm or less. It is preferably present, and more preferably 8 mm or less.
The ratio of the length of the cooling segment and the length of the filter segment (cooling segment: filter segment) to the length in the major axis direction of the non-combustion heating type tobacco 10 is not particularly limited, but the delivery amount of the fragrance and the appropriate aerosol temperature are not particularly limited. From the viewpoint of the above, it is usually 0.60 to 1.40: 0.60 to 1.40, preferably 0.80 to 1.20: 0.80 to 1.20, and 0.85 to 1. It is more preferably 15: 0.85 to 1.15, further preferably 0.90 to 1.10: 0.90 to 1.10, and 0.95 to 1.05: 0.95 to 1.15. It is particularly preferably 1.05.
By setting the ratio of the lengths of the cooling segment and the filter segment within the above range, the cooling effect, the effect of suppressing the loss due to the adhesion of the generated vapor and aerosol to the inner wall of the cooling segment, and the air volume and flavor of the filter. The adjustment function of is well-balanced, and good flavor and strength of flavor can be realized. In particular, if the cooling segment is long, atomization of aerosols and the like is promoted and a good flavor can be realized, but if it is too long, the passing substances will adhere to the inner wall.

The aeration resistance in the long axis direction per non-combustion heat-not-burn cigarette 10 is not particularly limited, but from the viewpoint of ease of sucking, it is usually 8 mmH ₂ O or more, preferably 10 mmH ₂ O or more, preferably 12 mmH. It is more preferably ₂ O or more, and usually 100 mmH ₂ O or less, preferably 80 mmH ₂ O or less, and more preferably 60 mmH ₂ O or less.
Ventilation resistance is measured according to the ISO standard method (ISO 6565: 2015), for example, using a filter aeration resistance measuring instrument manufactured by Cerulean. The ventilation resistance is a predetermined air flow rate (17.5 cc / min) from one end face (first end face) to the other end face (second end face) in a state where air is not permeated on the side surface of the non-combustion heat-not-burn tobacco 10. ) Refers to the pressure difference between the first end face and the second end face when the air is flowed. The unit is generally expressed in mmH ₂ O. It is known that the relationship between the aeration resistance and the length of non-combustion heat-not-burn tobacco is proportional in the length range (length 5 mm to 200 mm) that is usually carried out, and if the length is doubled, it is not. The ventilation resistance of combustion-heated cigarettes is doubled.

[Mouthpiece part]
The configuration of the mouthpiece portion 14 includes a cooling segment 12 and a filter segment 13 including a filter filter medium, and the cooling segment 12 is the tobacco rod portion 11 and the filter segment 13 with respect to the axial direction of the non-combustion heat-not-burn tobacco 10. There is no particular limitation as long as it is configured to be sandwiched adjacent to and. Hereinafter, the filter segment and the cooling segment will be described in detail.

(Filter segment)
The filter segment 13 is not particularly limited as long as it includes a filter filter medium and has a function as a general filter. For example, a tow made of synthetic fibers (also simply referred to as “tow”) or a material such as paper can be used. Those processed into a columnar shape can be used. The general functions of the filter include, for example, adjustment of the amount of air mixed when sucking aerosol, etc .; reduction of flavor; reduction of nicotine and tar; etc., but it is not possible to have all of these functions. I don't need it. In addition, in the case of electrically heated tobacco products, which produce less components than cigarette products and tend to have a lower filling rate of tobacco filling, the tobacco filling can be dropped while suppressing the filtration function. Preventing is also one of the important functions.

The shape of the filter segment 13 is not particularly limited, and a known shape can be adopted, and usually a columnar shape can be adopted, and the following aspects can be used.
Further, the filter segment 13 may be provided with a cavity (center hole or the like) or a recess or the like having a hollow cross section in the circumferential direction.

The cross-sectional shape of the filter segment 13 in the circumferential direction is substantially circular, and the diameter of the circle can be appropriately changed according to the size of the product, but is usually 4.0 mm or more and 9.0 mm or less. It is preferably 5 mm or more and 8.5 mm or less, and more preferably 5.0 mm or more and 8.0 mm or less. If the cross section is not circular, the diameter in the circle is applied when the above diameter is assumed to be a circle having the same area as the area of the cross section.
The circumferential length of the cross-sectional shape of the filter segment 13 in the circumferential direction can be appropriately changed according to the size of the product, but is usually 14.0 mm or more and 27.0 mm or less, and 15.0 mm or more and 26.0 mm or less. It is preferably 16.0 mm or more, and more preferably 25.0 mm or less.
The axial length of the filter segment 13 can be appropriately changed according to the size of the product, but is usually 15 mm or more and 35 mm or less, preferably 17.5 mm or more and 32.5 mm or less, and 20.0 mm. As mentioned above, it is more preferable that it is 30.0 mm or less. The shape and dimensions of the filter filter medium can be appropriately adjusted so that the shape and dimensions of the filter segment 13 are within the above range.

The ventilation resistance per 120 mm of the axial length of the filter segment 13 is not particularly limited, but is usually 40 mmH ₂ O or more and 300 mmH ₂ O or less, preferably 70 mmH ₂ O or more and 280 mmH ₂ O or less, and 90 mmH. It is more preferably ₂ O or more and 260 mmH ₂ O or less.
The above ventilation resistance is measured according to the ISO standard method (ISO6565), for example, using a filter ventilation resistance measuring instrument manufactured by Cerulean. The ventilation resistance of the filter segment 13 is a predetermined air flow rate (17.5 cc /) from one end face (first end face) to the other end face (second end face) in a state where air is not permeated on the side surface of the filter segment 13. min) Refers to the difference in air pressure between the first end face and the second end face when air is flowed. The unit is generally expressed in mmH ₂ O. It is known that the relationship between the ventilation resistance of the filter segment 13 and the length of the filter segment 13 is proportional to the length range (length 5 mm to 200 mm) that is normally carried out, and if the length is doubled, it is known. , The ventilation resistance of the filter segment 13 is doubled.

As the filter filter medium constituting the filter segment 13, for example, one manufactured by a manufacturing method described later may be used, or a commercially available product may be used.
Further, the embodiment of the filter segment 13 is not particularly limited, and may be a plain filter including a single filter filter medium; a multi-segment filter including a plurality of filter filter media such as a dual filter and a triple filter; and the like.

The filter segment 13 can be produced by a known method. For example, when a synthetic fiber such as cellulose acetate tow is used as a material for a filter filter medium, a polymer solution containing a polymer and a solvent is spun and crimped. It can be manufactured by the method. As the method, for example, the method described in International Publication No. 2013/067511 can be used.
In the production of the filter segment 13, it is possible to appropriately design the adjustment of the aeration resistance and the addition of additives (known adsorbents and fragrances (for example, menthol), granular activated carbon, fragrance holders, etc.) to the filter filter media.

The mode of the filter filter medium constituting the filter segment 13 is not particularly limited, and a known mode may be adopted. For example, a cellulose acetate tow processed into a columnar shape can be mentioned. The single thread fineness and total fineness of the cellulose acetate tow are not particularly limited, but in the case of a mouthpiece portion having a circumference of 22 mm, the single thread fineness is 5 g / 9000 m or more, 12 g / 9000 m or less, and the total fineness is 12000 g / 9000 m or more, 35000 g. It is preferably / 9000 m or less. Examples of the cross-sectional shape of the cellulose acetate tow fiber include a circular shape, an elliptical shape, a Y-shape, an I-shape, and an R-shape. In the case of a filter filled with cellulose acetate tow, triacetin may be added in an amount of 5% by weight or more and 10% by weight or less based on the weight of the cellulose acetate tow in order to improve the hardness of the filter. Further, instead of the acetate filter, a paper filter filled with sheet-shaped pulp paper may be used.

The density of the filter media is not particularly limited, but is usually 0.10 g / cm ³ or more and 0.25 g / cm ³ or less, and preferably 0.11 g / cm ³ or more and 0.24 g / cm ³ or less. , 0.12 g / cm ³ or more, more preferably 0.23 g / cm ³ or less.

In addition to synthetic fibers such as cellulose acetate tow, the filter filter medium may include a crushable additive release container (eg, a capsule) containing a crushable outer shell such as gelatin. The embodiment of the capsule (also referred to as "additive release container" in the art) is not particularly limited and known embodiments may be adopted, for example, crushable additive release containing a crushable outer shell such as gelatin. It can be a container. In this case, when the capsule is destroyed before, during or after use by the user of the tobacco product, it releases the liquid or substance (usually a flavoring agent) contained in the capsule and then the liquid or The substance is transmitted to tobacco smoke during use of the tobacco product and to the surrounding environment after use.
The form of the capsule is not particularly limited, and may be, for example, a easily destructible capsule, and the shape thereof is preferably a sphere. The additive contained in the capsule may contain any of the above-mentioned additives, but it is particularly preferable to include a flavoring agent and activated carbon. Also, as an additive, one or more materials that help filter smoke may be added. The form of the additive is not particularly limited, but is usually liquid or solid. The use of capsules containing additives is well known in the art. Destructible capsules and methods for producing them are well known in the art.

The filter segment 13 may further include a center hole segment having one or more hollow portions. The center hole segment is usually arranged closer to the cooling segment than the filter filter medium, and preferably adjacent to the cooling segment.

The center hole segment is composed of a packed bed having one or more hollow portions and an inner plug wrapper (inner roll paper) covering the packed bed. For example, the center hole segment is composed of a packed bed having a hollow portion and an inner plug wrapper covering the packed bed. The center hole segment has a function of increasing the strength of the mouthpiece portion. The packed bed has, for example, an inner diameter of φ1.0 mm or more and φ5. The rod can be 0 mm or less. Since the packed bed has a high packing density of fibers, air and aerosol flow only in the hollow portion during suction, and hardly flow in the packed bed. Since the packed layer inside the center hole segment is a fiber-filled layer, the feeling of touch from the outside during use does not cause a sense of discomfort to the user. The center hole segment may not have an inner plug wrapper and its shape may be maintained by thermoforming.

The center hole segment and the filter filter medium may be connected by, for example, an outer plug wrapper (outer winder). The outer plug wrapper can be, for example, cylindrical paper. Further, the tobacco rod portion 11, the cooling segment 12, and the connected center hole segment and filter filter medium may be connected by, for example, a mouthpiece lining paper. For these connections, for example, the inner surface of the mouthpiece lining paper is coated with glue such as vinyl acetate glue, and the tobacco rod portion 11, the cooling segment 12, and the connected center hole segment and filter filter medium are put and wound. You can connect with. It should be noted that these may be connected in a plurality of times by a plurality of lining papers.

From the viewpoint of improving the strength and the structural rigidity, the filter segment 13 may include a winding paper (filter plug winding paper) for winding the above-mentioned filter filter medium and the like. The aspect of the roll paper is not particularly limited and may include a seam containing one or more rows of adhesive. The adhesive may include a hot melt adhesive, further the hot melt adhesive may contain polyvinyl alcohol. When the filter segment 13 is composed of two or more segments, it is preferable that the roll paper is wound by winding these two or more segments together.
The material of the roll paper is not particularly limited, and a known material can be used, and a filler such as calcium carbonate may be contained.
The thickness of the roll paper is not particularly limited, and is usually 20 μm or more and 140 μm or less, preferably 30 μm or more and 130 μm or less, and more preferably 30 μm or more and 120 μm or less.

Due to the presence of the opening V, air flows into the cooling portion from the outside during use, and the temperature of the components and air flowing in from the tobacco rod portion 11 can be lowered. Further, by setting the position where the cooling segment 12 is provided within the region of 4 mm or more in the direction toward the cooling segment from the boundary between the cooling segment 12 and the filter segment 13, not only the cooling capacity is improved but also the cooling segment 12 is generated by heating. It is possible to suppress the retention of the component in the cooling segment and improve the delivery amount of the component.
When an aerosol base material is used for the tobacco rod portion 11, the vapor containing the aerosol base material and the tobacco flavor component generated by heating the tobacco rod portion 11 comes into contact with the air from the outside and the temperature drops. This can liquefy and promote the formation of aerosols.
Further, when the open holes V existing concentrically are treated as one open hole group, the open hole group may be one or two or more. When there are two or more openings, the area less than 4 mm from the boundary between the cooling segment 12 and the filter segment 13 in the direction toward the cooling segment is opened from the viewpoint of improving the delivery amount of the component generated by heating. It is preferable not to provide a group of holes.

It is preferable that the opening is provided at a position directly above the opening V. When producing such a non-combustion heat-not-burn tobacco 10, a chip paper 15 having an opening that overlaps with the opening V may be prepared and wound, but from the viewpoint of ease of manufacture, the opening may be made. After producing the non-combustion heat-not-burn tobacco 10 using the cooling segment 12 having no V, it is preferable to make a hole through the cooling segment 12 and the chip paper 15 at the same time.

The opening V is the air inflow ratio from the opening when sucked at 17.5 ml / sec by an automatic smoking machine (air flowing in from the opening when the ratio of the air sucked from the mouthpiece end is 100% by volume). The volume ratio) is preferably 10 to 90% by volume, preferably 50 to 80% by volume, more preferably 55 to 75% by volume, and for example, the number of holes V per opening group. Can be selected from the range of 5 to 50, the diameter of the opening V selected from the range of 0.1 to 0.5 mm, and can be achieved by a combination of these selections.
The above air inflow ratio can be measured by a method compliant with ISO9512 using an automatic smoking machine (for example, a single-barreling automatic smoking machine manufactured by Borgwald).

The region where the opening V exists is not particularly limited, but from the viewpoint of improving the delivery of the component generated by heating, a region of 2 mm or more in the direction toward the cooling segment from the boundary between the cooling segment 12 and the filter segment 13. It is preferably a region of 3 mm or more, more preferably a region of 4 mm or more, particularly preferably a region of 5 mm or more, and most preferably a region of 5.5 mm or more.

(Fragrance-containing material)
The perfume-containing material is a material in which the perfume is contained in the gel of the polysaccharide, and by blending the perfume-containing material in the tobacco rod portion 11, variation in the perfume delivery amount for each puff is suppressed from the early stage to the late stage of smoking. , Good flavor can be continuously obtained. The present inventors speculate that the reason is as follows. First, the non-combustion heating type tobacco is inserted into an electric heating type device, and smoking is started after preheating for a certain period of time. Since it volatilizes and most of it is delivered in the early stage of smoking, it is considered that the amount of perfume delivered is insufficient in the late stage of smoking. On the other hand, when the perfume-containing material is blended in the tobacco rod portion 11, since the perfume is coated with the gel of the polysaccharide, the volatilization of the perfume during the preheating is suppressed, and the perfume gradually increases during smoking. It is released. Therefore, it is presumed that a sufficient amount of fragrance delivery can be secured even in the late smoking period.

The same method as in Example 1 was applied except that the one to which menthol was added was used as the tobacco filler, and the non-combustible heat-not-burn tobacco of Comparative Example 1 was prepared. The amount of non-combustion heat-not-burn tobacco flavor delivered was evaluated in the same manner as in Example 1. The results are shown in Table 1 and FIG. 7 below.

From Table 1 and FIG. 7 above, in Comparative Example 1 in which the fragrance menthol was directly added to the tobacco chopped, most of the menthol was delivered in the first to fourth puffs, and the amount of menthol delivered in the subsequent puffs. It turned out to be significantly reduced. On the other hand, in Example 1 in which the tobacco rod portion contains tobacco nicks and a fragrance-containing material, the amount of menthol delivered for each puff is small from the early stage to the late stage of smoking, and a sufficient amount of menthol is delivered even in the late stage of smoking. Was confirmed.

From the above experimental results, it was shown that the present invention can provide non-combustion heat-not-burn tobacco with little variation in the amount of perfume delivered for each puff from the early stage to the late stage of smoking.
