Description

The present invention relates to a cartridge for smoking articles.

2. Description of the Related Art In recent years, there have been widely known tobacco products in which vaporized tobacco components are inhaled by heating a tobacco cartridge containing tobacco components without using a flame. In addition, due to the diversification of tastes, cartridges for enjoying the aroma and flavor of plants containing no tobacco components without using flames, like cigarettes, are beginning to become known. Such a cartridge or the like is used by being attached to a heating type smoking article.

As heating-type smoking tools, for example, a blade-heating type and an induction-heating type are known. Patent Document 1, for example, discloses a configuration of a cartridge used in an induction heating smoking tool. In the tobacco product described in Patent Document 1, a tobacco sheet (aerosol-forming substrate) containing an aerosol-forming body and susceptor particles is folded into a rod shape and wrapped with a wrapper. When this tobacco product is attached to an induction-heating smoking tool and the switch is turned on, an alternating current flows through a coil built into the smoking tool, thereby generating an alternating magnetic field. As a result, an induced current flows through the susceptor particles and the susceptor particles are heated by induction. Then, heat is transferred from the susceptor particles to the aerosol-forming body, thereby heating the aerosol-forming body and generating an aerosol.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view of a smoking article cartridge according to this embodiment, and FIG. 2 is a cross-sectional view taken along line II-II of FIG.

As shown in FIGS. 1 and 2 , the smoking article cartridge 1 according to this embodiment includes a heated body 20 , a mouthpiece 30 , and an exterior member 40 . The heated body 20 is formed in a cylindrical shape and arranged along the central axis C of the smoking article cartridge 1 . The mouthpiece 30 is arranged side by side on one end side of the object to be heated 20 in the axial direction. The exterior member 40 is a sheet-like member made of paper, for example, and wraps and integrates the heated body 20 and the mouthpiece 30 .

Here, the smoking implement cartridge 1 shown in FIG. 1 is formed to have a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm, for example. Of course, the smoking implement cartridge 1 may be formed in other dimensions.

The object to be heated 20 is formed by winding a plurality of aerosol-forming base materials 23 , which are fillers, with a sheet-like packaging member 25 . The diameter of the heated body 20 is, for example, about 7 mm. The thickness of the packaging member 25 is, for example, about 1.5 mm, and the inner diameter of the packaging member 25 (the diameter of the plurality of aerosol-forming substrates 23) is, for example, about 4 mm.

The object to be heated 20 has a cylindrical central portion 20a extending in its axial direction and a cylindrical outer peripheral portion 20b arranged so as to cover the central portion 20a. It covers around the portion 20b. The central portion 20a consists of a plurality of first aerosol-forming substrates 23a. The outer peripheral portion 20b consists of a plurality of second aerosol-forming substrates 23b different from the plurality of first aerosol-forming substrates 23a. The diameter of the central portion 20a is approximately half the inner diameter of the packaging member 25 (for example, 2 mm). The inner diameter of the outer peripheral portion 20 b is approximately equal to the diameter of the central portion 20 a , and the outer diameter of the outer peripheral portion 20 b is approximately equal to the inner diameter of the packaging member 25 .

One axial end of the heated body 20 is in contact with the mouthpiece 30 . On the other hand, one end of the object to be heated 20 and the other end on the opposite side are not covered with a cover member (for example, paper), and the aerosol-forming substrate 23 is exposed. The packaging member 25 is made of paper, for example, but any material can be used as long as it is a sheet-shaped member.

The plurality of aerosol-forming substrates 23 (first aerosol-forming substrate 23a, second aerosol-forming substrate 23b) consists of a number of members made from tobacco plants or non-tobacco plants. Each aerosol-forming substrate 23 is composed of a strip-shaped member, and arranged in a bundle such that the longitudinal direction of each member is along the central axis C. As shown in FIG. Also, the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b contain a susceptor made of a metallic material. The susceptor is induction-heated by generating an alternating magnetic field. Although the details will be described later, the susceptor content is different between the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b.

The mouthpiece 30 is a part that constitutes the mouthpiece of the smoking device cartridge 1, and is formed using paper or the like, for example. Mouthpiece 30 may also include a cellulose acetate filter or the like that removes particulates. Part of the fine particles in the water vapor and aerosol generated by the heated body 20 is filtered by the filter of the mouthpiece 30 .

Next, detailed configurations of the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b will be described with reference to FIGS. 3 and 4. FIG. FIG. 3 is a schematic diagram showing the first aerosol-forming substrate 23a, and FIG. 4 is a schematic diagram showing the second aerosol-forming substrate 23b.

As shown in FIG. 3, the first aerosol-forming substrate 23a is strip-shaped and contains a first susceptor 27a and a non-tobacco material 28. As shown in FIG. The first susceptor 27a is made of a magnetic metal material and is formed into a granular shape. Magnetic substances are roughly classified into ferromagnetic substances, paramagnetic substances, and diamagnetic substances. A ferromagnetic material is a material that strongly assumes magnetism in the same direction as the external magnetic field when an external magnetic field is applied and remains strong magnetism even when the external magnetic field is zero. Examples include iron, nickel, cobalt, and ferritic stainless steel. be done. The relative magnetic permeability of a ferromagnetic material is much greater than 1. For example, iron is about 5000, nickel is about 600, cobalt is about 250, and ferritic stainless steel is about 250. It is about 1000-1800.

On the other hand, a paramagnetic material is a material that becomes weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and loses its magnetism when the external magnetic field is reduced to zero. Examples thereof include aluminum, platinum, and manganese. The relative permeability of a paramagnetic material is slightly greater than 1. For example, aluminum is about 1.000021, platinum is about 1.000265, and manganese is about 1.000830. A diamagnetic material is a material that becomes weakly magnetized in the direction opposite to the external magnetic field when an external magnetic field is applied, and loses its magnetism when the external magnetic field is reduced to zero. Examples thereof include copper, graphite, and bismuth. The relative magnetic permeability of a diamagnetic material is slightly less than 1. For example, copper is about 0.999990, graphite is about 0.99980, and bismuth is about 0.999834. .

In ferromagnetic metal materials, when an alternating magnetic field is generated, an induced current flows and Joule heat is generated. Induction heating is easier than with a diamagnetic metal material, and the aerosol-forming substrate 23 can be sufficiently heated.

In addition, the ferromagnetic metal material has a high Curie temperature, for example, about 358° C. for nickel. Therefore, even when the smoking device cartridge 1 is heated at a high temperature of, for example, 200° C., the heating temperature does not reach the Curie temperature, the property as a ferromagnetic material can be maintained, and the aerosol-forming base material 23 can be stabilized. Can be heated. Therefore, in the present embodiment, nickel, which is a ferromagnetic metal material, is used as the material of the first susceptor 27a, and nickel particles formed in granular form are used as the first susceptor 27a. In addition to nickel particles, iron particles, cobalt particles, ferritic stainless steel particles, or a combination of these metal particles may be employed. Also, the first susceptor 27a may be configured to contain the magnetic metal material described above, and may employ an alloy containing, for example, 60% or more, preferably 80% or more. Even in this case, the aerosol-forming substrate 23 can be sufficiently heated by inductively heating the ferromagnetic metal material. A paramagnetic metal material or a diamagnetic metal material may be used instead of the ferromagnetic metal material. Even in this case, induction heating itself is possible. However, from the viewpoint of shortening the heating time and reducing power consumption, it is preferable to use a ferromagnetic metal material. The grain size of the first susceptor 27a is generally within the range of 200 μm to 500 μm. The non-tobacco material 28 is linearly formed.

On the other hand, as shown in FIG. 4, the second aerosol-forming substrate 23b is strip-shaped and contains a second susceptor 27b and a non-tobacco material . The second susceptor 27b is also made of the same metal material (nickel particles) as the first susceptor 27a.

As shown in FIGS. 3 and 4, a first content of the first susceptor 27a included in the first aerosol-forming substrate 23a and a second content of the second susceptor 27b included in the second aerosol-forming substrate 23b. different from Specifically, the second content is greater than the first content, the second content is 60-70% by mass, and the first content is 30-40% by mass.

The shape of the first susceptor 27a and the second susceptor 27b is not limited to granular, and may be linear, for example.

Next, specific examples of tobacco plants or non-tobacco plants that are raw materials used as aerosol-forming substrates 23 (first aerosol-forming substrate 23a, second aerosol-forming substrate 23b) will be described. The first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b are each composed of any one or a combination of raw materials shown below.

Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts and processed products can also be used. The forms of the extract include liquid, starch syrup, powder, granules, solution and the like.

Aerosol formers as raw materials for the aerosol-forming substrate 23 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, citric acid. triethyl acid, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate and the like. Among them, glycerin and propylene glycol are preferred.

Microcrystalline cellulose as a raw material for the aerosol-forming substrate 23 is obtained, for example, by partially depolymerizing α-cellulose obtained from fibrous plant pulp with an acid, and a soluble portion is extracted from the cellulose. is removed and the insoluble portion is crystallized accordingly.

The microcrystalline cellulose may be used as a powder, or may be dispersed in a solvent such as water and used as a liquid suspension. In this case, a high-speed stirrer, a high-pressure homogenizer, or the like can be used for dispersion in the solvent.

Furthermore, a flavor additive for adding flavor is preferably used as a raw material for the aerosol-forming substrate 23 as necessary. Examples of flavor additives include mint, cocoa, coffee, black tea extract, catechin powder of tea extract, and the like. As the preservative, those used in foods are preferred, and examples thereof include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate and the like.

The aerosol-forming substrate 23 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to those obtained from natural products, and may be synthetic products. Mint, mint, peppermint oil, and others containing menthol may also be used.

Flavor additives are applied to the mouthpiece 30 , for example by impregnating the walls of the mouthpiece 30 . The aspect in which the flavor additive is provided in the mouthpiece 30 is not limited to this aspect. A flavor additive may be provided at 30 . Alternatively, a flavor additive may be arranged between the mouthpiece 30 and the heated body 20 . When the flavor additive is enclosed in a capsule, the smoker can break the capsule by pressing the capsule with a finger, and can volatilize the aromatic component of the flavor additive at a desired timing. Become.

Furthermore, when the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided on the heated body 20 .

(Method for producing aerosol-forming substrate)
The method for manufacturing the aerosol-forming base material 23 described above will be described in each step. The manufacturing process of the aerosol-forming base material 23 includes a drying/pulverizing step of drying/pulverizing a tobacco plant or non-tobacco plant as a main raw material and weighing, etc., and a preparatory step of pre-treating other raw materials, weighing, etc. , a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition.

In the drying and pulverizing step, the used parts of tobacco plants or non-tobacco plants (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.), which are the main raw materials, are processed into predetermined pulverized products in order to make compositions. . In this case, it is preferable to adjust the water content to be convenient for absorbing or supporting the aerosol former, water and other components to be added later. In drying, the temperature is preferably 60°C or higher and 80°C or lower. By setting it in this range, it is easy to reach the desired amount of water while avoiding the dissipation of the required flavor component. Furthermore, the drying/pulverizing step can be provided with a sieving step for sieving the pulverized material, and the pulverized material can be adjusted to a desired particle size and fed to the mixing step.

In the preparation step, raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. For example, nickel particles with a particle size of 200 μm to 500 μm are prepared as the first susceptor 27a and the second susceptor 27b. In addition, the aforementioned microcrystalline cellulose is weighed in the preparatory step and put into the mixing step.

A normal mixer can be used in the mixing step. For example, it is preferable to use a form in which the raw materials in the mixing tank are mixed with a stirring blade while applying a shearing force. When producing the composition that serves as the base of the first aerosol-forming substrate 23a, the composition is mixed with various raw materials while containing 30 to 40% by mass of nickel particles, for example. In addition, when producing the composition that serves as the base of the second aerosol-forming substrate 23b, the composition is mixed with various raw materials while containing, for example, 60 to 70% by mass of nickel particles.

In the filling forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form strip-shaped aerosol-forming substrates 23 . In this embodiment, a three-roll mill is prepared to obtain a thin sheet. When a three-roll mill is used, it is possible to form a sheet of a desired thickness with a doctor blade while performing kneading, dispersion, etc. by compression by being pushed between narrow rolls and shearing by the difference in roll speed. preferable. Moreover, it can also be manufactured using a press roller or a press machine.

Other means may be used in the filling molding step, such as molding the composition through an orifice under pressure. In addition, in the filling molding step, if necessary, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be further added, and water etc. may be added. Also good.

The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut into a predetermined width by a cutter, a rotary cutter of rotary blade type, or the like.

Here, in the case of imparting adhesiveness to the surface of the strip-shaped aerosol-forming substrate 23, there is no particular limitation as long as it is a means capable of imparting adhesiveness. It should be attached.

(Manufacturing method of heated body)
Next, a method for manufacturing the heated body 20 by wrapping the aerosol-forming substrate 23 produced by the above steps with the packaging member 25 will be described with reference to FIG. 5A and 5B are diagrams showing the manufacturing process of the object to be heated 20. FIG.

As shown in FIG. 5, the packaging member 25 is placed on the opening/closing portion 61 of the pedestal 60, and a predetermined amount of the second aerosol-forming substrate 23b is placed on the packaging member 25. As shown in FIG. At this time, the plurality of second aerosol-forming substrates 23b are arranged flat. Next, a predetermined amount of the first aerosol-forming substrate 23a is placed on these second aerosol-forming substrates 23b. At this time, the plurality of first aerosol-forming substrates 23a are stacked near the central portion of the plurality of second aerosol-forming substrates 23b. The pair of opening/closing parts 61 provided on the pedestal 60 is configured to be movable in directions away from each other.

Next, the pair of opening/closing sections 61 are moved in a direction away from each other to form a recess (not shown) into which the packaging member 25 falls, and the aerosol-forming substrate 23 is cylindrically wrapped with the packaging member 25 that has fallen into the recess. At this time, a plurality of second aerosol-forming substrates 23b are arranged along the inner peripheral surface of the packaging member 25, and a plurality of first aerosol-forming substrates 23a are arranged inside these second aerosol-forming substrates 23b. be. Then, both ends of the packaging member 25 are adhered to fill the interior of the packaging member 25 with the aerosol-forming substrate 23 . Thus, the object to be heated 20 is completed.

(Method of using cartridge for smoking device)
Next, a method of using the smoking implement cartridge 1 will be described with reference to FIG. FIG. 6 is a cross-sectional view of the smoking article cartridge 1 inserted into the smoking article 70. As shown in FIG.

As shown in FIG. 6, the smoking article cartridge 1 is used by being attached to an induction heating smoking article 70 . The smoking implement 70 includes an insertion portion 71 for inserting the cartridge 1 for smoking implements, a coil 72 incorporated so as to be cylindrically wound around the insertion portion 71, and an alternating current being controlled to flow through the coil 72. a circuit board (not shown) including a CPU that When the smoking implement cartridge is inserted into the insertion portion 71 , the heated body 20 is placed inside the coil 72 . In this state, when the smoking tool 70 is turned on, an alternating current flows through the coil 72 under the control of the CPU, and an alternating magnetic field is generated so as to penetrate the plurality of aerosol-forming substrates 23 of the heated body 20 . As a result, an induced current flows through the first susceptor 27a of the first aerosol-forming substrate 23a and the second susceptor 27b (see FIGS. 3 and 4) of the second aerosol-forming substrate 23b to generate Joule heat and hysteresis. Since heat is generated by the loss, the first susceptor 27a and the second susceptor 27b are heated by induction. Heat is transferred from the susceptors 27a and 27b to the aerosol-forming substrates 23, thereby heating the aerosol-forming substrates 23 and generating aerosols. At this time, since the second content rate of the second susceptor 27b is higher than the first content rate of the first susceptor 27a, the heating temperature of the outer peripheral portion 20b can be substantially equal to the heating temperature of the central portion 20a. In this state, when the smoker holds the mouthpiece 30 in his mouth and inhales, the aerosol flows through the mouthpiece 30 and into the smoker's mouth.

According to the smoking implement cartridge 1 according to the present embodiment configured in this way, the following effects can be obtained.

The first aerosol-forming substrate 23a arranged in the central portion 20a of the object to be heated 20 contains the first susceptor 27a at a first content, and the second aerosol-forming substrate 23b arranged in the outer peripheral portion 20b contains the first susceptor 27a. contains the second susceptor 27b at a second content different from the first content. Therefore, by appropriately adjusting the first content rate and the second content rate, it is possible to reduce the difference in heating temperature between the central portion 20a and the outer peripheral portion 20b, thereby suppressing uneven heating of the aerosol-forming substrate 23. . In addition, if the second content rate is larger than the first content rate as in the present embodiment, the heating temperature of the outer peripheral portion 20b can be substantially equal to the heating temperature of the central portion 20a, and the aerosol-forming substrate 23 heating unevenness can be reliably suppressed.

In addition, since the first susceptor 27a and the second susceptor 27b are formed in the form of granules, the susceptors 27a and 27b can be easily and evenly distributed over the aerosol-forming base material 23 in the manufacturing stage, thereby heating the smoking device cartridge 1. Sometimes heat can be evenly transferred across each aerosol-forming substrate 23 . Furthermore, if the first susceptor 27a and the second susceptor 27b are linearly formed, the susceptors 27a and 27b can be in sufficient contact with the aerosol-forming substrate 23, and heat can be efficiently transferred.

Next, various modifications of the cartridge for smoking articles will be described.

(Modification 1)
In the smoking implement cartridge according to Modification 1, the first susceptor 27a is made of a granular metal material (for example, nickel particles), and the second susceptor 27b is made of a linear metal material (for example, nickel wire). It differs from the above embodiment in that The linear second susceptor 27b is attached to the surface of the second aerosol-forming substrate 23b via an adhesive. The second susceptor 27b has a diameter of, for example, 0.9 mm and a length of, for example, 12 mm. In order to sufficiently heat the second aerosol-forming substrate 23b, it is preferable to attach a plurality of (for example, four) second susceptors 27b having such a size to the surface of the second aerosol-forming substrate 23b. According to the smoking implement cartridge having such a configuration, a sufficient contact area can be secured between the second aerosol-forming substrate 23b and the second susceptor 27b in the outer peripheral portion 20b of the heated body 20, and the heating temperature is low. The outer peripheral portion 20b, which tends to become brittle, can be sufficiently heated in the same manner as the central portion 20a. Therefore, uneven heating of the aerosol-forming substrate 23 can be more reliably suppressed. In addition, since the linear second susceptor 27b is more easily induction-heated than the granular second susceptor 27b, the second aerosol-forming substrate 23 can be effectively heated.

The shape of the second susceptor 27b is not limited to linear, and may be strip-shaped, for example. In this case, a strip-shaped second susceptor 27b is attached to the surface of the second aerosol-forming substrate 23b via an adhesive. The thickness of the strip-shaped second susceptor 27 b is, for example, 0.1 mm, and the vertical and horizontal lengths are substantially the same as those of the second aerosol-forming substrate 23 . According to the smoking implement cartridge having such a configuration, a sufficient contact area between the second aerosol-forming base material 23b and the second susceptor 27b can be ensured in the outer peripheral portion 20b of the heated body 20 . Moreover, since the strip-shaped second susceptor 27b is more easily induction-heated than the granular or linear second susceptor 27b, the second aerosol-forming substrate 23 can be heated more effectively.

(Modification 2)
The smoking implement cartridge according to Modification 2 differs from Modification 1 in that the first susceptor 27a and the second susceptor 27b are made of linearly formed metal material (for example, nickel wire). According to the smoking implement cartridge having such a configuration, not only the second susceptor 27b but also the first susceptor 27a are linearly formed, thereby forming the first aerosol contained in the central portion 20a of the heated body 20. Both the substrate 23a and the second aerosol-forming substrate 23b included in the peripheral portion 20b can be uniformly heated. As in Modification 1, the shape of the second susceptor 27b is not limited to linear, and may be strip-shaped, for example. Even in this case, the same effects as described above can be obtained.

(Modification 3)
The smoking implement cartridge according to Modification 3 differs from the above embodiment in that each of the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b includes a susceptor having a different shape. Specifically, the first susceptor 27a is formed in a granular shape and contained in the first aerosol-forming substrate 23a, and is formed in a linear shape and adhered to the surface of the first aerosol-forming substrate 23a. . The second susceptor 27b is also formed in a granular shape and contained in the second aerosol-forming substrate 23b, and is also formed in a linear shape and adhered to the surface of the second aerosol-forming substrate 23b. According to the smoking implement cartridge having such a configuration, the surfaces of the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b are heated by the linearly formed first susceptor 27a and second susceptor 27b. The inside of the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b can be heated by the first susceptor 27a and the second susceptor 27b, which are formed into granules. Therefore, the first aerosol-forming substrate 23a and the second aerosol-forming substrate 23b can be evenly heated. As in Modification 1, the linear first susceptor 27a and the linear second susceptor 27b may be formed into strips, for example. Alternatively, one of the first susceptor 27a and the second susceptor 27b may be formed in a linear shape, and the other may be formed in a strip shape. Even in this case, the same effects as described above can be obtained.

(Modification 4)
The smoking implement cartridge according to Modification 4 differs from the above embodiment in that the first susceptor 27a is not included in the first aerosol-forming substrate 23a. That is, in this smoking device cartridge, the first content of the first susceptor 27a is 0% by mass. According to the smoking implement cartridge having such a configuration, the first aerosol-forming substrate 23a can be heated by inserting, for example, a blade-shaped heating body. Therefore, the smoking implement cartridge 1 can be used not only for induction heating smoking implements 70 but also for blade heating smoking implements. Therefore, it is possible to provide a smoking implement cartridge that can meet the preferences of smokers.

(Modification 5)
The smoking implement cartridge according to Modification 5 differs from the above embodiment in that a support member for supporting the aerosol-forming substrate 23 is provided between the heated body 20 and the mouthpiece 30 . The support member has a channel that transfers the aerosol generated by the heated body 20 to the mouthpiece 30 . Aerosol passing through the channel is cooled by the support member. According to the smoking article cartridge having such a configuration, even if the first susceptor 27a and the second susceptor 27b are induction-heated at a high temperature by an induction-heating smoking article, the aerosol generated at a high temperature is dissipated by the support member. Sufficient cooling allows the smoker to smoke comfortably.
