JP7595165B2 - Flavor molded body for non-combustion heating type flavor inhaler, manufacturing method thereof, and non-combustion heating type flavor inhaler - Google Patents

Description

The present invention relates to a flavor molded body for a non-combustion heating type flavor inhaler and a method for producing the same, as well as a non-combustion heating type flavor inhaler.

In a combustion type flavor inhaler (cigarette), a flavor is obtained by burning a tobacco filler containing tobacco leaves. As an alternative to the combustion type flavor inhaler, a non-combustion heating type flavor inhaler has been proposed, which heats a flavor source containing tobacco material instead of burning it to obtain a flavor. The heating temperature of the non-combustion heating type flavor inhaler is lower than the combustion temperature of the combustion type flavor inhaler, for example, about 400°C or less. Since the heating temperature of the non-combustion heating type flavor inhaler is thus low, in order to increase the amount of smoke, an aerosol generating agent such as glycerin is added to the flavor source in the non-combustion heating type flavor inhaler. The aerosol generating agent is vaporized by heating to generate an aerosol. The aerosol is supplied to the user together with flavor components such as tobacco components, so that the user can obtain a sufficient flavor. For example, Patent Document 1 discloses a flavor source for a combustion type flavor inhaler. Patent Document 2 discloses a flavor source for a non-combustion heating type flavor inhaler.

However, flavor sources for non-combustion heating type flavor inhalers have the following problems. When the flavor source for a non-combustion heating type flavor inhaler is in powder form, it is necessary to fill the pot or rolling paper with the flavor source when using it, and since the flavor source is usually sticky, it is desirable to improve the ease of handling. On the other hand, when the flavor source for a non-combustion heating type flavor inhaler is a tobacco sheet, the tobacco sheet is filled in the tobacco rod part and heated when using it, but after use (after heating), the strength decreases and it cannot maintain its shape and becomes tattered, making post-processing difficult. Furthermore, it is desirable for the flavor source for a non-combustion heating type flavor inhaler to volatilize the flavor components stably throughout the entire use.

The present invention aims to provide a flavor molded body for a non-combustion heating type flavor inhaler that is easy to handle, has high strength even after use, and from which flavor components volatilize stably throughout use, a method for producing the same, and a non-combustion heating type flavor inhaler.

[Flavor molded body for non-combustion heating type flavor inhaler]
The flavor molded body for a non-combustion heating type flavor inhaler according to the present embodiment (hereinafter also referred to as the flavor molded body) includes a tobacco powder raw material, an adsorbent that adsorbs a volatile flavor component, and an aerosol source. Here, the compression breaking strength of the flavor molded body by a stake-shaped plunger measured using a tablet hardness tester is 10 N or more.

The flavor molded body according to this embodiment has a certain size and shape as a molded body, so that stickiness is suppressed, and since it has high strength, it is easy to handle as it is, and there is no need to fill it into a pot or wrapping paper. In addition, the flavor molded body according to this embodiment forms a carbonized layer on the heated surface, improving the breaking strength, so that it has high strength even after use (after heating). Therefore, the shape of the molded body can be sufficiently maintained even after use, and it is easy to post-process. Furthermore, in the flavor molded body according to this embodiment, the volatile flavor components are adsorbed to an adsorbent such as activated carbon, so that the volatile flavor components are gradually released from the adsorbent by heating, and the flavor components volatilize stably throughout the entire use. In addition, since the amount of moisture in the molded body can be suppressed by being adsorbed to the adsorbent, it is easy to mold during molding.

(Tobacco powder raw material)
Examples of tobacco powder raw materials include tobacco leaves, tobacco veins, stems, roots, flowers, etc., which have been chopped into powder form. The type of tobacco leaf is not particularly limited, and may be, for example, flue-cured, burley, native, oriental, or fermented leaves thereof. These tobacco powder raw materials may be used alone or in combination of two or more.

The average particle size of the tobacco powder raw material is not particularly limited, but is preferably 100 μm or less. By having the average particle size of 100 μm or less, a flavor molded body with higher strength can be obtained. The average particle size is preferably 5 to 80 μm, more preferably 10 to 60 μm, and even more preferably 20 to 50 μm. The average particle size is measured using a light scattering method.

(volatile fragrance ingredients, adsorbents)
Examples of volatile fragrance components include, but are not limited to, phenethyl acetate, ethyl hexanate, isoamyl acetate, benzyl acetate, ethyl octanate, ethyl oleate, phenethyl alcohol, acetoanisole, benzaldehyde, benzyl alcohol, menthol, carvone, cinnamic acid, cinnamaldehyde, cinnamyl alcohol, vanillin, ethyl vanillin, citronellol, 2,5-dimethylpyrazine, limonene, furaneol, cyclotene, decanoic acid, ethyl isovalerate, valeric acid, palmitic acid, ethyl salicylate, geraniol, guaiacol, β-ionone, linalool, linalyl acetate, nerolidol, piperonal, sotolone, α-terpineol, megastigmatrienone, damascenone, neophthaldiene, etc. These volatile fragrance components may be used alone or in combination of two or more.

The volatile flavor component is adsorbed to the adsorbent. That is, the volatile flavor component is held in the adsorbent, and can be adsorbed and held in the pores of the adsorbent. Examples of the adsorbent include activated carbon, silica gel, ion exchange resin, molecular sieve, zeolite, etc. These adsorbents may be used alone or in combination of two or more. Among these, activated carbon is preferred as the adsorbent, because it can adequately hold the volatile flavor component, and when the non-combustion heating type flavor inhaler is a microwave heating type flavor inhaler or an induction heating type flavor inhaler as described below, it can generate heat when heated and increase the amount of volatilization of the flavor component in the initial stage of use. Note that activated carbon is not usually used in flavor sources for combustion type flavor inhalers, because it may generate carbon monoxide when burned.

From the viewpoint of being able to sufficiently retain the volatile flavor component, the specific surface area of the adsorbent is preferably 500 to 3000 m ² /g, and more preferably 700 to 2500 m ² /g. The specific surface area is measured by the BET method. The amount of the volatile flavor component adsorbed by the adsorbent is preferably 1 to 20 parts by mass, and more preferably 5 to 10 parts by mass, per 100 parts by mass of the adsorbent. The amount of the adsorbent adsorbing the volatile flavor component contained in the flavor molded body is preferably 5 to 40 parts by mass, and more preferably 10 to 30 parts by mass, per 100 parts by mass of the tobacco powder raw material.

In this embodiment, it is preferable that the adsorbent is composed of a plurality of particles, and two or more of the particles are contained in the flavor molded body. By containing two or more adsorbent particles in the flavor molded body, the adsorbent particles are dispersed in the flavor molded body, and the amount of flavor component volatilized in each puff is more stabilized. The average particle size of the adsorbent particles is not particularly limited, but can be, for example, 0.3 to 2.0 mm. The average particle size is measured using a dry sieve method.

In this embodiment, it is preferable that the adsorbent is not exposed on the surface of the flavor molded body. If the adsorbent is not exposed on the surface of the flavor molded body, the appearance is good, and when the flavor molded body is molded, the adsorbent such as activated carbon does not adhere to the molding machine, improving manufacturing efficiency. For example, by covering the surface of a flavor molded body containing an adsorbent with a component of a flavor molded body that does not contain an adsorbent, a flavor molded body can be obtained in which the adsorbent is not exposed on the surface. It is possible to visually confirm that the adsorbent is not exposed on the surface of the flavor molded body.

(Aerosol Source)
Examples of the aerosol source include glycerin, propylene glycol, etc. These aerosol sources may be used alone or in combination of two or more. The amount of the aerosol source contained in the flavor molded product is preferably 5 to 30 parts by mass, more preferably 10 to 20 parts by mass, per 100 parts by mass of the tobacco powder raw material.

(Other ingredients)
The flavor molded body of this embodiment may contain, in addition to the tobacco powder raw material, the adsorbent that adsorbs the volatile flavor component, and the aerosol source, for example, cellulose powder, tea powder, Lamiaceae plant powder, Umbelliferae plant powder, etc.

(Physical properties, shape, etc. of flavor molded body)
The flavor molded body according to this embodiment has a compression breaking strength of 10 N or more measured by a stake-type plunger using a tablet hardness tester. The compression breaking strength of 10 N or more provides good handleability and high strength even after use. The compression breaking strength is preferably 10 to 200 N, more preferably 20 to 150 N, and even more preferably 30 to 120 N. The compression breaking strength is specifically a value before heating measured by the method described below.

The shape of the flavor molded body according to this embodiment is not particularly limited, but may be, for example, a tablet shape, a plate shape, a cylindrical shape, a rod shape, a sphere shape, a hollow shape, a porous shape, etc., and from the viewpoint of ease of use and maintaining strength, a tablet shape is preferable. When the flavor molded body is in a tablet shape, its size may be, for example, a diameter of 5 to 15 mm and a height of 5 to 10 mm.

[Method for manufacturing a flavor molded body for a non-combustion heating type flavor inhaler]
The method for producing a flavor molded body for a non-combustion heating type flavor inhaler according to the present embodiment includes the following steps: a step of mixing a tobacco powder raw material, an adsorbent that adsorbs a volatile flavor component, ethanol, and an aerosol source to form a mixture (hereinafter also referred to as a "raw material mixing step"); a step of compression molding the mixture (hereinafter also referred to as a "compression molding step"); and a step of removing at least a portion of the ethanol from the mixture (hereinafter also referred to as an "ethanol removal step"). The method according to the present embodiment allows the flavor molded body according to the present embodiment to be produced efficiently and simply.

In particular, in the method according to the present embodiment, by adding ethanol in the raw material mixing step, a resin composition derived from the tobacco powder raw material migrates to the surface of the tobacco powder raw material, and the tobacco powder raw material and the like are bonded to each other via the resin composition, so that it is presumed that a flavor molded body having high strength is obtained. In addition, it is presumed that the addition of ethanol dehydrates some of the hydroxyl groups of the cellulose contained in the tobacco powder raw material and condenses with nearby cellulose, so that a flavor molded body having high strength is obtained. In this way, in the method according to the present embodiment, it is not necessary to use a general binding agent (binder) during molding, and most of the ethanol used is removed, so that a flavor molded body having high strength can be obtained without affecting the flavor.

Each step in the method according to this embodiment will be described below, but the method according to this embodiment may include steps other than the raw material mixing step, the compression molding step, and the ethanol removal step. In addition, the ethanol removal step may be performed during the compression molding step, as long as it is performed after the raw material mixing step, or may be performed after the compression molding step.

(Raw material mixing process)
In this step, a mixture is formed by mixing tobacco powder raw material, an adsorbent that has adsorbed a volatile flavor component, ethanol, and an aerosol source. The amount of ethanol mixed is preferably 1 to 20 parts by mass per 100 parts by mass of tobacco powder raw material. By mixing 1 part by mass or more of ethanol per 100 parts by mass of tobacco powder raw material, a flavor molded body having higher strength can be obtained. Furthermore, by mixing 20 parts by mass or less of ethanol per 100 parts by mass of tobacco powder raw material, compression molding can be easily performed. In this step, it is more preferable to mix 3 to 17 parts by mass of ethanol per 100 parts by mass of tobacco powder raw material, and even more preferable to mix 5 to 15 parts by mass of ethanol.

In this process, in addition to the tobacco powder raw material, the adsorbent that adsorbs the volatile flavor components, the ethanol, and the aerosol source, other components such as cellulose powder, tea powder, Lamiaceae plant powder, and Umbelliferae plant powder can be further mixed. In particular, cellulose powder can further improve the strength of the flavor molded body. The method of mixing the raw materials is not particularly limited, but they can be mixed using a general mixer such as a V-type mixer.

(Compression molding process)
In this step, the mixture obtained in the raw material mixing step is compression molded. The compression molding machine used for compression molding is not particularly limited, but examples thereof include rotary tablet presses. The conditions for compression molding are not particularly limited, but it is preferable to mold at a compression pressure of 2 kN or more. As described above, at least a part of the ethanol may be removed by natural drying, for example, during compression molding.

(Ethanol removal process)
In this step, at least a portion of the ethanol is removed from the mixture. As described above, the removal of at least a portion of the ethanol may be performed on the mixture during the compression molding step, or on a molded body obtained after the compression molding step.

In this process, it is preferable to remove at least a part of the ethanol at 10 to 40°C. By removing at least a part of the ethanol at 10°C or higher, the ethanol can be sufficiently removed. In addition, by removing at least a part of the ethanol at 40°C or lower, the influence of heating on the flavor can be suppressed. The temperature when removing at least a part of the ethanol is more preferably 15 to 35°C, and even more preferably 20 to 30°C. When removing at least a part of the ethanol at 10 to 40°C, for example, by drying at 10 to 40°C for 30 to 180 minutes, at least a part of the ethanol can be removed. At least a part of the ethanol can be removed, for example, by using an electric oven, hot air drying, a tunnel dryer, natural drying, etc. In addition, it is preferable to remove the ethanol in an open state, not in an enclosed space.

By this process, it is preferable that 90% or more by weight of the ethanol contained in the mixture (molded body) is removed, more preferably 95% or more by weight, even more preferably 99% or more by weight, and it is particularly preferable that all of the ethanol is removed.

[Non-combustion heating type flavor inhaler]
The non-combustion heating type flavor inhaler according to the present embodiment includes a flavor source container that contains the flavor molded body according to the present embodiment, a power supply unit that includes a power supply unit, and a heating unit that receives power from the power supply unit to heat the flavor molded body in the flavor source container. Since the non-combustion heating type flavor inhaler according to the present embodiment includes the flavor molded body according to the present embodiment, the flavor component can be stably supplied to the user throughout the entire use. In addition, the flavor molded body has good handleability and is strong even after use, making post-processing easy.

The non-combustion heating type flavor inhaler is preferably a microwave heating type flavor inhaler or an induction heating type flavor inhaler. When the non-combustion heating type flavor inhaler is a microwave heating type flavor inhaler or an induction heating type flavor inhaler, the adsorbent contained in the flavor molded body can be activated carbon. When the non-combustion heating type flavor inhaler is a type that uses a heater to heat by heat transfer, it takes some time for the flavor source to reach the temperature required for aerosol generation in the early stages of use, so the amount of volatilization of the flavor components in the early stages of use is small. However, when the non-combustion heating type flavor inhaler according to this embodiment is a microwave heating type flavor inhaler or an induction heating type flavor inhaler and the adsorbent contained in the flavor molded body is activated carbon, the activated carbon itself generates heat when heated, so that the activated carbon becomes hotter more quickly even in the early stages of use, and the amount of volatilization of the flavor components in the early stages of use increases. Therefore, the flavor components can be volatilized more stably throughout the entire use.

An example of an induction heating type flavor inhaler according to this embodiment is shown in Figure 1. The induction heating type flavor inhaler 1 shown in Figure 1 (a) comprises a flavor source container 3 that contains a flavor molded body 2 according to this embodiment, a power supply unit 4 equipped with a power supply unit, a heating unit 6 that receives power from the power supply unit and induction heats the flavor molded body 2 in the flavor source container 3, and a control unit 5 that controls the temperature of the heating unit 6. The flavor source container 3 is detachable within a chamber 7 of the heating unit 6, and when in use, the flavor source container 3 is inserted into the chamber 7 of the heating unit 6. Power is supplied to the heating unit 6 from the power supply unit of the power supply unit 4 in response to an instruction from the control unit 5, and the flavor molded body 2 is heated by induction heating.

1(b) shows an enlarged view of the heating unit 6 of the induction heating type flavor inhaler 1 shown in FIG. 1(a). The induction coil 8 of the heating unit 6 is embedded in a mold 9 made of a heat-dissipating non-magnetic material with high thermal conductivity. A shielding layer 10 for shielding electromagnetic wave leakage is formed on the outer periphery of the mold 9. Although not shown in FIG. 1(b), a heat-resistant resin layer such as PEEK may be formed on the inside of the mold 9. The flavor source container 3 also has a flow path 11 that can flow from the end face of the flavor source container 3 on the non-suction end side to the end face on the suction end side. The flavor source container 3 is inserted into the chamber 7 of the heating unit 6, and the flavor molded body 2 is heated by induction heating in the heating unit 6 to generate an aerosol containing flavor components, and the aerosol and flavor components can be supplied to the user by the user inhaling the aerosol through the flow path 11. The heating temperature by induction heating is preferably 150 to 400° C., and more preferably 200 to 350° C. The heating temperature refers to the temperature of the heating part.

Another example of the non-combustion heating type flavor inhaler according to the present embodiment is shown in FIG. 2. The non-combustion heating type flavor inhaler 12 shown in FIG. 2 includes a raw material chamber 18 in which the flavor molded body 2 according to the present embodiment can be placed, a battery 14, a heater 15 that receives power from the battery 14 to heat the flavor molded body 2, a control unit 13 that controls the temperature of the heater 15, and a mouthpiece 19. In the raw material chamber 18, the flavor molded body 2 is fixed by a raw material position adjustment jig 17. The flavor molded body according to the present embodiment is suppressed from becoming sticky, has high strength, and is easy to handle, so there is no need to fill it in a pot or wrapping paper, and it can be directly fixed and placed in the raw material chamber, for example, as shown here. The heater 15 is heated by power being supplied from the battery 14 to the heater 15 according to an instruction from the control unit 13. The heat from the heater 15 is transmitted to the flavor molded body 2 through the metal plate 16, and the flavor molded body 2 is heated. Heating the flavor molded body 2 generates an aerosol containing flavor components, and the aerosol and flavor components are supplied to the user by the user inhaling through the mouthpiece 19. The heating temperature is preferably 150 to 400° C., and more preferably 200 to 350° C. The heating temperature refers to the temperature of the heater.

The present embodiment will be described in detail below with reference to examples, but the present embodiment is not limited to these examples. The measurements of compressive breaking strength before and after heating, the measurements of TPM amount over time, and the sensory evaluation were performed by the following methods.

[Measurement of compressive breaking strength before and after heating]
The compression breaking strength of the prepared flavor molded body was measured before and after heating using a tablet hardness tester with a stake-type plunger. Regarding the measurement before heating, specifically, a stake-type plunger (product name: tablet hardness tester TH-1, manufactured by AS ONE) was gradually lowered against the flavor molded body at room temperature (22 ° C.), and the strength when the flavor molded body was compressed and broken was measured three times using a tablet hardness tester (product name: tablet hardness tester TH-1, manufactured by AS ONE). The average value of the three measurements was taken as the compression breaking strength (N). Regarding the measurement after heating, specifically, the flavor molded body was heated at 40 ° C. for 2 hours, cooled to room temperature, and the compression breaking strength was measured in the same manner as the measurement before heating. In addition, the stake-type plunger has a conical shape on the contact side with the measurement sample, and since the measurement sample is pressed at the apex of the cone shape, a high pressure can be applied to one point.

[Measurement of TPM amount over time]
For the prepared flavor molded bodies, the amount of TPM over time was measured using an external heating type flavor inhaler and an induction heating type flavor inhaler by the following method.

(1) Externally heated flavor inhaler The prepared flavor molded body was filled into the raw material chamber of an externally heated flavor inhaler, PAX (trade name, manufactured by PAX Labs), and the flavor molded body was heated from the outside by heat transfer when the PAX was turned on. The aerosol generated by heating was collected at regular intervals, and the mass of the collected matter (total particulate matter (TPM) amount) was measured and evaluated.

(2) Induction heating type flavor inhaler The flavor molded body prepared was placed in an aluminum cup 20 as shown in FIG. 3. Here, a plurality of minute vent holes were provided in the bottom of the cup 20, and an aluminum plate (not shown) was placed on the bottom of the cup 20, and the flavor molded body 2 was placed on top of it. The mass of the flavor molded body placed in the cup 20 was the same as the mass of the flavor molded body filled in the raw material chamber in the external heating type flavor inhaler of (1). The cup 20 was placed in an induction heating device equipped with an induction coil 8, and the flavor molded body 2 was heated by induction heating. The aerosol generated by induction heating was collected at regular intervals and evaluated by measuring its mass (total particulate matter (TPM) amount).

[Sensory evaluation]
300 mg of the prepared flavor molded body was filled into the raw material chamber of an externally heated flavor inhaler PAX3 (trade name, manufactured by PAX Labs), and the flavor molded body was heated from the outside by heat transfer by turning on the PAX. The aerosol generated by heating was inhaled by seven expert evaluation panels, and sensory evaluation was performed by freely providing comments at 1-10 puffs (early use), 11-25 puffs (early use), 26-40 puffs (late use), and 41-50 puffs (late use). The seven expert evaluation panels were fully trained in sensory evaluation of non-combustion heating flavor inhalers, and it was confirmed that the evaluation thresholds were equal and unified among the expert evaluation panels.

[Example 1]
1 g of KURARAY COAL (trade name, manufactured by Kuraray Co., Ltd., granular activated carbon, specific surface area: 500-2500 m2/g) was added to 10 ml of a fragrance component solution having a fragrance composition (concentration ratio) (phenethyl acetate: 613 ppm by mass, ethyl hexanate: 341 ppm by mass, isoamyl acetate: 560 ppm by mass, benzyl acetate: 350 ppm by mass, ethyl octanate: 632 ppm by mass, ethyl oleate: ⁶³⁵ ppm by mass) and the mixture was shaken for 30 minutes. The recovered activated carbon was placed on an aluminum dish and dried for 60 minutes with a ceramic heater set at 60°C. In this way, activated carbon adsorbing a volatile fragrance component (fragrance-adsorbed activated carbon) was prepared. The amount of the volatile fragrance component adsorbed by the activated carbon was 3 parts by mass relative to 100 parts by mass of activated carbon.

1 part by mass of ethanol and 20 parts by mass of glycerin were added to 100 parts by mass of tobacco powder raw material (leaf tobacco, Brazilian flue-cured tobacco) having an average particle size of 30 μm, and the mixture was lightly mixed with a spatula and shaken for 30 minutes. Furthermore, 30 parts by mass of activated carbon adsorbing the volatile flavor components was added to 100 parts by mass of the tobacco powder raw material and mixed to obtain a mixture. The obtained mixture was molded into a tablet shape at a compression pressure of 3 kN using a compression molding machine (product name: TDP 0, manufactured by LFA Machines Oxford Ltd). The obtained molded body was dried at 40 ° C for 3 hours, and the ethanol contained in the molded body was removed to obtain a flavor molded body. The compression breaking strength of the flavor molded body before and after heating was measured by the above method. The results are shown in Table 1.

[Example 2]
Except for changing the amount of ethanol to 10 parts by mass per 100 parts by mass of the tobacco powder raw material, a flavored molded product was produced in the same manner as in Example 1, and the compression breaking strength was measured before and after heating. The results are shown in Table 1.

[Example 3]
A flavor molded body was produced in the same manner as in Example 1, except that the amount of ethanol added was changed to 20 parts by mass of ethanol per 100 parts by mass of tobacco powder raw material, and the compression breaking strength was measured before and after heating. The results are shown in Table 1. The amount of TPM over time was also measured for the obtained flavor molded body using the method described above. The measurement results using the external heating type flavor inhaler are shown in Figure 4, and the measurement results using the induction heating type flavor inhaler are shown in Figure 5. Furthermore, the obtained flavor molded body was subjected to a sensory evaluation using the method described above. The results are shown in Table 2.

As shown in Table 1, it was confirmed that the compression breaking strength of the flavor molded body according to this embodiment does not decrease after heating, but rather improves. Also, as shown in Table 2, it was confirmed that the flavor components volatilize stably throughout the entire use of the flavor molded body according to this embodiment. This can also be understood from Figures 4 and 5. In particular, as shown in Figure 5, when an induction heating type flavor inhaler is used as a non-combustion heating type flavor inhaler, the amount of flavor components volatilized increases, especially in the early stages of use, compared to when an external heating type flavor inhaler shown in Figure 4 is used, and the flavor components can be volatilized more stably throughout the entire use.
