Description

The technical field to which the invention belongs

[0001]

The present invention relates to an aroma-producing article to be heated, an aroma cartridge, which is installed in a chamber provided with an electrically controlled heating element of a heated smoking device so as to be in contact with the heating element, and which can emit smoke and an aroma component of an aerosol formed during heating the heating element; and a manufacturing method and apparatus for manufacturing a flavor-producing article to be heated.

State of the art

[0002]

In recent years, tobacco cessation has become widespread in indoor environments, including workplaces, restaurants, etc., where people of all ages gather, and although the number of flame-burning tobacco smokers is rapidly declining, the number of electronic tobacco cartridge smokers is rapidly increasing. having an aerosol-producing article comprising an aerosol former that generates an aerosol by means of heat using a heated smoking device having an electrically controlled heating element in the chamber. Accordingly, various electronic tobacco products for enjoying heated smoking have been sold. The reason for this is that such heating-type smoking reduces the inhalation of harmful components resulting from the thermal decomposition and combustion of conventional tobacco. Therefore, the development of e-tobacco product technologies (eg, Patent Documents 1 to 5) is being actively pursued.

[0003]

Although the mechanism of such heated smoking varies depending on the shape of the heated smoking device or electronic tobacco cartridge and the like, a typical example is shown below. When an electronic tobacco cartridge with an aerosol-generating article at one end and a mouthpiece at the other end is mounted and heated so that the aerosol-producing article is in contact with the heat source of the heating smoking device, the volatiles containing the aerosol former are released from the aerosol-generating article, and the volatiles are drawn in towards the mouthpiece at the other end along with air by simultaneous tightening by the smoker. During the transport process, the volatile components of the aerosol former are cooled and condensed to form a smoke-like aerosol. Along with this, other volatile substances create flavor in the mouth and nose of the smoker. As a result, the smoker can enjoy smoking. Thus, in the case of heated smoking, it has been shown that smoking is possible at a temperature of about 200 to 350°C, at which an aerosol former such as glycerol or propylene glycol contained in an aerosol-producing article can volatilize, i.e. at a temperature at which the thermal decomposition of tobacco leaves begins.

[0004]

On the other hand, in the case of conventional flame smoking in which tobacco is burned with a flame, combustion requires a temperature exceeding at least 600°C, and a maximum smoking temperature may reach 900°C. It is generally believed that the amount of harmful substances formed increases with increasing temperature. It follows from this that the amount of harmful substances formed during heating-type smoking is extremely small.

[0005]

In addition, the content of tobacco leaves in the aerosol-producing article is low, and an appropriate material design is employed. Tobacco stalk, leaf pieces and tobacco dust, and the like obtained in a conventional tobacco manufacturing process may also be used. The result is an efficient use of materials and reduced material costs.

[0006]

However, in the case of cigarette tobacco, as described in Patent Document 6, a tobacco wrapping method and apparatus capable of forming a gas flow path suitable for smoking have been developed. The tobacco wrapping device includes a draw portion for air conveying the supplied cut tobacco upwards, a suction portion supplied with negative pressure for air conveying the cut tobacco upward in the draw portion, and an endless tobacco belt stretched between the draw portion and the suction portion, which is driven into action synchronously with the stringer tape. The device for wrapping tobacco includes a cutting device. The cut feeder draws the cut tobacco to the bottom surface of the tobacco belt at the suction portion. Thereafter, the tobacco strip drawing in the cut tobacco is formed into a rod shape by a plurality of guides, and the rod-shaped cut tobacco is transported to the wrapping tube portion. The tobacco wrapper also includes a stringer band that is fed and driven at a controlled speed. The tobacco wrapping device also includes a wrapping tube (paper wrapping part) on a stringer belt that continuously wraps the rod-shaped cut tobacco supplied from the cut feeding device into a long wrapping paper continuously supplied from a roll. This device can be used to produce a large quantity of tobacco having a gas flow path suitable for smoking.

[0007]

The éclater disc, which is provided in the middle of a plurality of guides in the path of the tobacco web from the draw portion of the cutter to the wrapper tube to remove any excess cut tobacco drawn into the tobacco web, plays an important role in controlling the amount of filler of the rod-shaped cut tobacco being wrapped by the wrapper. tubular part. Thereafter, the rod-shaped tobacco wrapped in wrapping paper in the wrapping tubular portion is cut to the desired length in the cutting module and fed to the filter head in the next process. In the case of cigarette tobacco, cut tobacco has completely different shapes, is bulky and elastic. Thus, it is believed that such a tobacco wrapping method and apparatus has been developed.

[0008]

On the other hand, the electronic tobacco cartridge includes an aerosol producing article. The aerosol-producing article is heated by a heating element. The aerosol-producing article includes a composition that contains at least an aerosol former, such as glycerin or propylene glycol, and a tobacco plant and/or non-tobacco plant, as well as a binding agent. An aerosol-producing article is obtained by wrapping an aerosol-producing substrate with paper, which is obtained by cutting a sheet that is formed and processed from the composition. Therefore, the following problems arise. In order to solve these problems, it is necessary to optimize the shape and size of the aerosol-producing substrate, as well as to optimize the distribution and filling degree of the aerosol-producing substrate in an aerosol-producing article, etc., and to find a method and apparatus for wrapping the aerosol-producing substrate with paper with optimum hardness, and although various studies have been carried out (for example, Patent Documents 3, 4 and 7), a solution has not yet been found.

[0009]

First, unlike cigarette tobacco, there is a problem that it is extremely difficult to form a gas flow path suitable for smoking. An aerosol-producing substrate constituting an aerosol-producing article is obtained by cutting a sheet treated with a liquid aerosol former at room temperature, which is an essential component thereof, of a tobacco plant and/or a non-tobacco plant, as well as a binding agent, etc., into a rod shape, strip form, powder form, granule form, bead form, fine flake form, sheet form and fiber form. Therefore, when the aerosol-producing substrate is compared with cut tobacco constituting cigarette tobacco, it is due to characteristics such as high shape uniformity, small volume for the same weight, and plastic material with poor elasticity.

[0010]

Second, in the case of an electronic tobacco cartridge, it must not burn when the aerosol-forming substrate and the heating element come into contact and puff. Therefore, there is a problem that the temperature of the air flow at the time of suction cannot be raised excessively.

[0011]

Thirdly, the electronic tobacco cartridge is attached to and detached from the heating type smoking device. Therefore, it is necessary that the aerosol-producing article can be easily inserted into the heating element, and it is necessary to remove the aerosol-producing article from the heating element without dropping the tobacco-forming substrate.

Disclosure of the essence of the invention

Technical problem

[0013]

The aerosol-producing article is heated by a heating element. The aerosol-producing article includes a composition that contains at least an aerosol former, such as glycerin or propylene glycol, and a tobacco plant and/or non-tobacco plant, as well as a binding agent. An aerosol-producing article is obtained by wrapping an aerosol-producing substrate with paper, which is obtained by cutting a sheet that is formed and processed from the composition. Therefore, there is a problem that it is difficult to increase the filling ratio while maintaining the gas flow path due to the shape uniformity of the aerosol-producing substrate material, high volume specific gravity, and poor elasticity. When a comfortable smoking gas flow path is formed, the filling degree of the aerosol-producing substrate tends to be low, and there is a possibility that there is a problem of ignition during suction and falling out during attachment/detachment. On the contrary, in order to solve the problem of ignition during suction and dropout during attachment/disconnection, when the filling degree of the aerosol-producing substrate of the aerosol-producing article is increased, the gas flow rate inside the aerosol-producing article is reduced. Because of this, smokers cannot perform comfortable inhalation. In addition, the number of puffs per cigarette may increase and may exceed the proper number of puffs per cigarette because the volume of inhalation at a time is reduced. In addition, it becomes difficult to insert the aerosol-producing article into the heating element.

[0014]

Thus, the inventor of the present invention has found a method and apparatus for optimizing the shape and size of the aroma-producing substrate to be heated, optimizing the distribution and filling degree of the aroma-producing substrate to be heated in the aroma-producing article to be heated, and the like, and wrapping of the aroma-producing substrate to be heated with paper of optimal hardness to solve the conflicting problems as described above and to increase the degree of filling while maintaining the gas flow path, and has reached the completion of the present invention.

[0015]

Thus, it is an object of the present invention to provide an aroma producing article to be heated for an aroma cartridge and an aroma cartridge that optimizes the gas flow path and the filling degree, provides comfortable smoking, can provide an appropriate number of puffs, and allows the aroma producing article to be inserted easily. heating, into the heating element of the heated aroma device without the problem of ignition during puffing and falling off during attachment/disconnection, as well as a manufacturing method and apparatus for manufacturing a flavor-producing article to be heated.

[0016]

In the present invention, an aerosol-producing substrate, an aerosol-producing article, an electronic tobacco cartridge, and a heating-type smoking device are, respectively, an aroma-producing substrate to be heated, an aroma-producing article to be heated, an aroma cartridge, and a heated aroma device, based on the fact, that smoking in the present invention is not limited to enjoying smoking an aerosol produced by heating an aerosol-producing substrate containing a tobacco component and an aerosol-producing article obtained by wrapping an aerosol-producing substrate with paper, but smoking in the present invention includes enjoying the aroma of an aerosol produced by heating an aerosol-producing article that does not contain a tobacco component; and an aerosol-producing article. A cartridge referred to as "e-tobacco compatible cartridge" is simply defined as "a cartridge that can be used interchangeably (compatible) with an electronic tobacco cartridge containing a tobacco component", whether or not they contain a tobacco component.

[0017]

That is, "smoking" generally means the inhalation of smoke containing nicotine, tar, etc., which is generated by burning or heating tobacco leaves of Solanaceae tobacco or a material containing a tobacco component. However, in the present invention, "smoking" means "enjoying smoke", "tasting smoke", and "satisfied with smoke", and smoke elements are not limited to elements containing tobacco leaves or tobacco components, and only non-tobacco materials or non-tobacco components are also used. "Smoke" in the present invention also includes "what appears to be smoke" and "what is smoky" such as, for example, droplets dispersed in the air, such as an aerosol. In addition, the term "flavor" in the present invention means "good flavor" and includes a smell (fragrant) coming from the material itself, a smell (aroma) escaping into space when heated, and a smell (aroma) passing into the mouth when inhalation, and the like.

Solution of problems

[0018]

The present invention is an aroma-producing article to be heated, which is inserted into an electrically controlled heating element provided in a chamber of a heated aroma device and provided in an aroma cartridge, includes an aroma-producing substrate to be heated, wherein the aroma-producing substrate to be heated produces smoke and aromas when heated in contact with the heating element and wrapped with packing material. The aroma-producing substrate to be heated includes at least an aerosol former, a tobacco plant and/or a non-tobacco plant, and a binding agent. The aroma-producing substrate to be heated has a gas flow path formed by collecting the heated aroma-producing substrates into primary fills and a gas flow path consisting of voids formed by collecting the aroma-producing substrate to be heated and its the primary filler into the secondary filler, wherein the gas flow path from the voids formed by the aroma-producing substrate to be heated and its primary filler are in contact with the packaging material. These gas passages have a deformed gas flow passage which extends into the aroma-producing article to be heated. In an aroma-producing article to be heated having such a deformed gas flow path, the gas flow path is sufficiently protected. Therefore, the problem of ignition of the aroma-producing substrate to be heated during puffing can be solved, and the smoke and aroma of a sufficient amount of aerosol can be comfortably inhaled, and it can be easily inserted into the heating element of the aroma device to be heated. On the other hand, since the filling degree of the aroma-producing substrate to be heated is high, an appropriate number of puffs can be ensured, and the problem of the aroma-producing substrate to be heated can also be avoided when the aroma cartridge is attached/disconnected.

[0019]

In addition, in such a deformed gas flow path, when the central region and the outer peripheral region are evenly divided in area in a cross section perpendicular to the longitudinal direction of the aroma-producing article to be heated, it is preferable that the central region has a higher porosity than the outer peripheral region. to achieve the above effects.

[0020]

The flavor-producing substrate to be heated constituting such a flavor-producing article to be heated has a uniform shape in a cross section perpendicular to the longitudinal direction, and the ratio of the length of the long axis and the length of the short axis in the cross section perpendicular to the longitudinal direction is preferably from 1:1 up to 30:1, more preferably from 2:1 to 20:1 and even more preferably from 5:1 to 20:1. However, when the ratio of the length of the long axis and the length of the short axis is greater than 30:1, it is difficult to provide a gas flow path.

[0021]

As can be understood from this relationship, the cross-sectional shape perpendicular to the longitudinal direction of the aroma-producing substrate to be heated is not particularly limited, and may be an isotropic regular triangle, a square, a regular polygon such as a regular pentagon, and a circle. However, the ratio is preferably 2:1 or more, and is preferably approximately rectangular and approximately elliptical to provide a deformed gas flow path.

[0022]

Particularly, most preferably, the aroma-producing substrate to be heated has a cross-sectional shape of a substantially rectangular parallelepiped so that a gap can be formed and a gas flow channel provided. In particular, the length of the short axis of the cross section perpendicular to the longitudinal direction of such a cuboid shape is preferably 0.1 to 1.0 mm, more preferably 0.1 to 0.5 mm. The long axis length of the cross section perpendicular to the longitudinal direction of the cuboid shape is preferably 0.5 to 3.0 mm, more preferably 0.5 to 2.0 mm.

[0023]

Most preferably, the cross-sectional shape perpendicular to the longitudinal direction of the aroma-producing substrate to be heated is uniform in the longitudinal direction in order to ensure uniformity in the longitudinal direction of the aroma-producing article to be heated, in which the aroma-producing substrate to be heated is wrapped in packaging. material so that the gas flow path extends into the aroma-producing article to be heated.

[0024]

On the other hand, the relationship between the length of the short axis and the length in the longitudinal direction in the cross section perpendicular to the aroma-producing substrate to be heated constituting the aroma-producing article to be heated depends on the size of the chamber or the like of the heated aroma device in which the aroma cartridge is used. . Therefore, the causal relationship with the porosity in the cross section perpendicular to the longitudinal direction of the flavor-producing article to be heated is poor. However, in order to obtain a pleasant puff using a flavor-producing article to be heated having a deformed gas flow path according to the present invention, it is preferable that there is an appropriate length and the ratio between the length in the long axis direction and the length in the short axis direction is from 10:1 up to 700:1. The specific length in the longitudinal direction of the most preferred shape of a substantially rectangular parallelepiped as the aroma-producing substrate to be heated is also preferably 10 to 70 mm.

[0025]

In such a heated flavor-producing article to be heated having anisotropy in the shape of a cross section perpendicular to the longitudinal direction, the surface in the long axis direction in the cross section perpendicular to the longitudinal direction is more often in contact with the surface of the long axis direction in the cross section perpendicular to the longitudinal direction. of the adjacent aroma-producing substrate to be heated than the surface of the short axis direction of the cross section perpendicular to the longitudinal direction of the adjacent aroma-producing substrate to be heated. Therefore, the degree of filling can be increased while providing a channel for gas flow.

[0026]

In addition, in such a flavor-producing article to be heated having anisotropy in the cross-sectional shape perpendicular to the longitudinal direction, the number of flavor-producing substrates to be heated, where the direction of the long axis of the cross-section is perpendicular to the longitudinal direction of the flavor-producing substrate to be heated, is located in the tangential direction of the periphery of the aroma-producing substrate to be heated is greater than the number of heated aroma-producing substrates whose long axis direction coincides with the normal direction of the periphery of the aroma-producing article to be heated. Therefore, it is possible to increase the degree of filling while providing a channel for gas flow.

[0027]

Accordingly, when smoking an aroma cartridge provided with such an aroma-producing article to be heated by a heated aroma device, at the same time as performing pleasant smoking of the aerosol and inhaling the aroma, the filling degree of the aroma-producing substrate to be heated is increased, an appropriate number of puffs is provided, and the problem can be solved. igniting the aroma-producing substrate to be heated during puffing, and falling out of the aroma-producing substrate to be heated during attaching/detaching the aroma cartridge. Therefore, the fragrance cartridge can be easily inserted into the heating element provided in the chamber of the heated fragrance device.

[0028]

Then, in the aroma cartridge provided with the aroma-producing article to be heated, the mouthpiece preferably uses an element whose single filter extends continuously in the longitudinal direction together with the aroma-producing article to be heated. More preferably, however, the aroma cartridge comprises a support member configured to pass an airflow in the longitudinal direction connected to the aroma producing article to be heated in the longitudinal direction, and a filter connected in the longitudinal direction of the support element. The support member prevents the aroma-producing article to be heated from moving to the suction side. The filter filters the smoke and flavor of the aerosol to prevent fine particles and dust from the flavor-producing substrate being heated from entering the oral cavity. Thus, the smoker can enjoy a more comfortable smoking experience.

[0029]

Although the support member according to the present invention is not particularly limited, it is composed of a gas flow passage and a support portion. The support member is present at least on the outermost periphery and prevents the aroma-producing article to be heated from moving to the drawing side without preventing the drawing and maintains the shape of the aroma cartridge. The material is a general purpose polymer such as a polyolefin resin such as polyethylene or polypropylene, or a polyester resin. On the other hand, a commonly used cellulose acetate fiber filter can be used.

[0030]

However, both the conventional support element and the filter are also made from poorly biodegradable polymers. Therefore, there is a problem with the generation of an environmental pollutant such as microplastics. Therefore, the support element and filter according to the present invention are those made from biodegradable aliphatic polyester and biodegradable polymers based on starch and cellulose. In particular, polyethylene adipate (PEA), poly (ε-caprolactone) (PCL), poly (3-hydroxybutyrate) (PHB), poly (β-propiolactone) (PPL), poly (butylene succinate) can be preferably used as the aliphatic polyester. ) (PBS), poly(L-lactide) (PLA), and poly(p-dioxanone) (PPDO).

[0031]

Despite the high degree of filling of the aroma-producing substrate to be heated, the manufacturing method of the aroma-producing article to be heated plays an important role in forming the aroma-producing article to be heated having a deformed gas flow path in which the gas flow path is provided.

[0032]

Thus, the method for manufacturing an aroma-producing article to be heated according to the present invention includes: a first step of cutting a heated aroma-producing sheet containing at least an aerosol former, non-tobacco plants and/or tobacco plants, and a binding agent, to obtain an aroma-producing an elongate-shaped substrate to be heated, in which the shape, in a cross section perpendicular to the longitudinal direction, is uniform in the longitudinal direction and more than twice the length of the aroma-producing article to be heated; the second step of maintaining a predetermined amount of the elongate-shaped aroma-producing substrate to be heated with the belt, and placing the aroma-producing substrate of the elongated-shape to be heated on the packaging material web of the aroma-producing article to be heated having a predetermined width, being conveyed so that the aroma-producing the elongate-shaped substrate to be heated is parallel to the longitudinal direction of the packaging material web of the flavor-producing article to be heated; a third step of wrapping the elongate-shaped aroma-producing substrate to be heated with a web of packaging material of the aroma-producing article to be heated, so that the elongate-shaped aroma-producing substrate to be heated has a cylindrical shape in the longitudinal direction by bending the tape; a fourth step of linearly gluing the packaging material web of the aroma-producing article to be heated to the rod-shaped aroma-producing article to be heated produced in the third step along the longitudinal direction; and a fifth step of slicing the rod-shaped flavor-producing article to be heated, manufactured in the fourth step, into predetermined lengths.

[0033]

The third step of the method for manufacturing the aroma-producing article to be heated is the most important step in forming the deformed gas flow path in the aroma-producing article to be heated. In this step, the aroma-producing substrate of an elongated shape to be heated is aligned in the longitudinal direction of the aroma-producing article to be heated, placed in the longitudinal direction of the packaging material web of the aroma-producing article to be heated, supported and transported by the belt, and the long rod-shaped aroma-producing article to be heated is heating, is formed so that the aroma-producing substrate of an elongated shape to be heated is columnar in the longitudinal direction by the packaging material web of the aroma-producing product to be heated by bending the tape, and the internal structure of the aroma-producing product to be heated is determined. The reason for the formation of a deformed gas flow path with high porosity is that the primary filler collected by the movement of the elongated aroma-producing substrate to be heated forms a cavity due to the bending of the belt, and the secondary filler collected by the movement of the single elongate-shaped aroma-producing substrate article, to be heated, or its primary fill, form a cavity, and they form a deformed channel for gas flow, which passes into the aroma-producing article to be heated, and a single aroma-producing article of the elongated substrate to be heated, its primary fill and packaging material form a cavity , and this forms a deformed gas flow path which passes into the elongated flavor-producing article to be heated. On the other hand, the reason for increasing the filling ratio is that when the belt is bent at a later period of this step, the elongate-shaped aroma-producing substrate to be heated is rounded by the packaging material in the direction perpendicular to the longitudinal direction, and a cylindrical long rod-shaped aroma-producing article is formed, to be heated. Therefore, the closer the rod-shaped flavor-producing article to be heated approaches the cylindrical shape, the more the flavor-producing substrate of the elongated shape to be heated constituting the primary fill and the secondary fill of the flavor-producing substrate of the elongate shape to be heated moves as it slides, and the frequency at which the surface in the long axis direction in the cross section perpendicular to the elongate shaped aroma-producing substrate to be heated contacts the surface in the long-axis direction in the cross section perpendicular to the adjacent elongate shaped aroma-producing substrate to be heated increases, and the amount of aroma-producing substrates an elongated shape to be heated, in which the direction of the long axis is located in the tangential direction of the cylinder periphery, also increases. The filled state of the elongated flavor-producing substrate to be heated in the region of the outer periphery forms a stable and solid structure. In contrast, the central region of the rod-shaped flavor-producing article to be heated leaves bulk primary fillers and secondary fillers as described above. Therefore, the deformed gas flow path formed in the primary filler and the secondary filler remains, and the porosity of the central region becomes higher than that of the outer peripheral region. An aroma-producing article to be heated used for an aroma cartridge is obtained by cutting a rod-shaped aroma-producing article to be heated, the internal structure of which is thus formed. The aroma-producing article to be heated has exactly the same internal structure as this internal structure.

[0034]

That is, an elongate-shaped aroma-producing substrate to be heated, which is longer than the length in the longitudinal direction of the aroma-producing product to be heated, and has substantially the same cross-sectional shape, is placed in the longitudinal direction of the packaging material web of the aroma-producing product, to be heated, which has the shape of a roll and is rounded to have a columnar shape in the longitudinal direction. For this reason, the deformed gas flow path of the rod-shaped flavor-producing article to be heated becomes a through hole, and in the rounding process, since the flavor-producing substrate of the elongated shape to be heated forms a cylinder, a primary filler and a secondary filler are formed, a deformed channel is formed therein. for gas flow, and a deformed gas flow path may also be formed between the rod-shaped flavor-producing article to be heated and the packaging material. In this process, the primary filler and the secondary filler remain in the central region of the cylindrical rod-shaped flavor-producing substrate to be heated. However, in the outer periphery region, the contact frequency of the long axis direction in the perpendicular cross-section of the elongate-shaped aroma-producing substrate to be heated with the long-axis direction in the perpendicular cross-section of the adjacent elongate-shaped aroma-producing substrate to be heated increases, and the arrangement ratio in the tangential direction of the periphery cylinder increases and the degree of filling increases.

[0035]

In order to control this behavior, the shape of the elongated flavor-producing substrate to be heated is important, and it is preferable that the flavor-producing substrate of the elongated shape to be heated to be cut in the first step has a ratio of the length of the long axis and the length of the short axis of the cross section perpendicular to the longitudinal direction, from 1:1 to 30:1, and the ratio of the length of the longitudinal direction and the length of the short axis from 40:1 to 3600:1. In particular, the ratio of the length of the long axis and the length of the short axis is more preferably 2:1 to 20:1, and more preferably 5:1 to 20:1. These relationships are closely related to mobility, when the aroma-producing substrate of an elongated shape to be heated, located in the longitudinal direction, is formed into a columnar shape so that it can be wrapped in the longitudinal direction and the perpendicular direction, and the degree of filling can be increased while maintaining the channel for gas flow. Therefore, when the ratio of the lengths of the long axis and the lengths of the short axis in the cross section perpendicular to the longitudinal direction exceeds 30:1, and the ratio of the lengths in the longitudinal direction and the lengths of the short axis exceeds 3600:1, the frequency with which the aroma-producing product of the elongated shape to be heat, comes into contact with the surface in the direction of the long axis, increases, the mobility is extremely reduced, and it becomes difficult to form the primary filler and the secondary filler. In the case where the ratio of the length of the long axis to the length of the short axis is 1:1, the elongated flavor-producing article to be heated may be arranged similarly to the close-packed structure depending on the production conditions.

[0036]

The cross-sectional shape perpendicular to the longitudinal direction in the elongated flavor-producing substrate to be heated may be an isotropic triangle, a square, a regular polygon such as a regular pentagon, and a circle. However, it is more preferable that the cross-sectional shape is rectangular and elliptical, having a short axis and a long axis, and furthermore, it is preferable that the cross-section is substantially rectangular in order to form an anisotropic gas flow channel.

[0037]

From the foregoing, it is clear that the third step of rounding the aroma-producing substrate of the elongated shape to be heated according to the present invention into a cylinder in the longitudinal direction is characterized by providing a guide provided with a groove configured to gradually bend the tape into a cylindrical shape, together with the tape, passes through an elongated flavor-producing substrate to be heated, which is supported and transported onto a belt and onto a packaging material. This tape may also use a stringer tape such as described in, for example, Patent Document 8, which is used in cigarette tobacco.

[0038]

As can be seen from the above, in a cross section perpendicular to the longitudinal direction of the rod-shaped aroma-producing article to be heated, when the central region and the outer peripheral region are evenly divided in area, it is possible to increase the porosity of the central region compared to the porosity of the outer peripheral region. Thus, this state is reflected as it is in the aroma-producing article to be heated in the aroma cartridge.

[0039]

This is closely related to the fact that in the process of wrapping the aroma-producing substrate of an elongated shape to be heated having anisotropy in the shape of a cross section perpendicular to the longitudinal direction into the packaging material, and forming the primary filler and the secondary filler, the surface in the long axis direction in the transverse the cross section perpendicular to the longitudinal direction of the elongated flavor-producing substrate to be heated has a higher frequency of contact with the surface in the long axis direction in the cross section perpendicular to the longitudinal direction of the adjacent elongate flavor-producing substrate to be heated than the surface in the short axis direction in the transverse a section perpendicular to the longitudinal direction of the adjacent elongate shaped aroma-producing substrate to be heated. In addition, in this process, there is a close relationship in the fact that the number of elongate-shaped aroma-producing substrates to be heated, in which the direction of the long axis in a cross section perpendicular to the longitudinal direction in the elongate-shaped aroma-producing substrate to be heated, is located in the tangential direction. of the periphery in the rod-shaped aroma-producing article to be heated can be made larger than the number of elongate-shaped aroma-producing substrates to be heated in which the long axis direction is located in the normal direction of the periphery in the rod-shaped aroma-producing article to be heated.

[0040]

As described above, the shape of the elongate-shaped aroma-producing substrate to be heated has a great influence on the structure of the cross-section perpendicular to the longitudinal direction of the rod-shaped aroma-producing article to be heated. However, it is possible to control the cross-sectional structure perpendicular to the length direction of the rod-shaped flavor-producing article to be heated by the conveying speed of the belt, the shape of the guide, and the like.

[0041]

In addition, in order to easily perform longitudinal linear bonding of the heated flavor-producing packaging material, it is preferable to add the step of applying a predetermined amount of a hot melt adhesive to a predetermined position of the heated flavor-producing web of packaging material in parallel with the first step, and provide a heating means in the fourth step.

[0042]

Then, the manufacturing method of the aforementioned aroma-producing article to be heated can be continuously carried out with the following apparatus. In other words, an apparatus for manufacturing an aroma-producing article to be heated according to the present invention includes a feeder for an elongate-shaped aroma-producing substrate cut from a heated aroma-producing sheet containing at least an aerosol former, non-tobacco plants and/or tobacco plants, and binding agent; a feeder for a web of packaging material of a flavor-producing article to be heated; an endless belt drive system supporting and conveying the web of packaging material of the flavor-producing article to be heated; a guide including a plurality of grooves provided in the conveyance path of the endless belt; an adhesive device for a web of packaging material of a flavor-producing article to be heated; and a slicing machine for the rod-shaped aroma-producing article to be heated, wherein the rod-shaped aroma-producing article to be heated is made by wrapping the aroma-producing substrate to be heated with a web of packaging material of the aroma-producing article to be heated, all of which are continuously actuated.

Description of the embodiment

[0048]

In the following description, the present invention will be described in more detail using one embodiment, but the present invention is not limited thereto, and within the scope of legal protection that does not deviate from the gist of the present invention, various modifications can be made, and the present invention is limited only by the technical idea. described in the claims.

[0049]

fig. 1 is a schematic cross-sectional view of an aroma cartridge 1 provided with an aroma-producing article 2 to be heated having a deformed gas flow path, the cartridge 1 being cut in a longitudinal direction through a central axis. In the aroma cartridge 1, the aroma-producing article 2 to be heated and the mouthpiece 3 consisting of the support member 31 and the filter 32 are connected in the longitudinal direction. The aroma-producing article 2 to be heated is given a substantially cylindrical shape by bonding the aroma-producing substrate 21 to be heated with the packaging material of the aroma-producing article 22 to be heated. The support member 31 has a gas flow channel (1) 311 and a support portion (1) 314. As shown in FIG. 1, the fragrance-producing article to be heated 2 and the support member 31 are connected in the longitudinal direction by means of a coupling member 4 of the fragrance-producing article to be heated/support member. In addition, the cylindrical filter 32, which is a sponge porous material, is integrated as an aroma cartridge 1 in the longitudinal direction of the support member 31 via the aroma cartridge outer member 5, but the present invention is not limited to this.

[0050]

The aroma-producing substrate 21 to be heated includes at least an aerosol former, a tobacco plant and/or a non-tobacco plant, and a binding agent, which will be described in detail below.

[0051]

Those produced using PLA, which is a biodegradable plastic, are used as raw materials for the support element 31 and the filter 32, so that the fragrance cartridge 1 does not become an environmental pollutant.

[0052]

Aroma cartridge 1 from FIG. 1 has a maximum outer diameter of 6.5 to 7.5 mm and a length of 40 to 49 mm. The length of the aroma-producing article 2 to be heated is shortened to 11-13 mm. However, since these dimensions are determined depending on the chamber of the flavoring device to be heated, they are not limited thereto.

[0053]

fig. 2 is a cross-sectional view showing the usage diagram of the aroma cartridge 1. FIG. 2 is a schematic cross-sectional view of the aroma cartridge 1 shown in FIG. 1 and a heated aroma device 6, which are shown in a section in the longitudinal direction through the central axis. The heated fragrance device 6 includes an electrically controlled heating element 62 in the chamber 61. The fragrance cartridge 1 is inserted into the heated fragrance device 6. The fragrance cartridge 1 is inserted into the chamber 61 of the heated fragrance device 6.

In other words, the above average particle diameter refers to the diameter corresponding to the mass of 50% by integrating the mass from the larger hole with respect to the multi-sieve test result. In this case, it is more preferable that the average particle diameter is such that the residue on the 250 µm sieve is 8% by mass or less, and the residue on the 75 µm sieve is 45% by mass or more. In the case where the residue on the 250 µm sieve is 8% by mass or less, the sieved microcrystalline cellulose has the effect of preventing the sheet from being aggregated. In the case where the residue on the 75 µm sieve is 45% by mass or more, adhesion between the sheet and the metal roll can be prevented.

[0083]

The weight average molecular weight (Mw) of microcrystalline cellulose is preferably 10,000 to 200,000, more preferably 10,000 to 100,000, and even more preferably 20,000 to 60,000. excellent. When the amount is 100,000 or less, in addition to the effect of suppressing the aggregation of the sheet, the adhesion of the sheet and the metal roll can be effectively prevented.

[0084]

The molecular weight of cellulose can be measured using gel permeation chromatography (GPC). For example, the measurement method described in Japanese Patent Laid-Open Publication No. 6-109715 is used. If necessary, polyethylene glycol, etc. is used as a standard.

[0085]

Next, a manufacturing process of an elongate-shaped aroma-producing substrate 23 to be heated as a raw material for the production of an aroma-producing article to be heated will be described. An elongated flavor-producing substrate 23 to be heated is produced by a drying and pulverizing step of drying and pulverizing a non-tobacco plant serving as a main raw material and performing weighing, etc., a preparation step of performing pre-treatment, weighing, etc. .P. other raw materials, a mixing step for mixing the raw materials into a mixture, a shaping step in which the mixture is formed into a heated flavor-producing sheet, and a cutting step of cutting the sheet to obtain an elongated flavor-producing substrate 23 to be heated.

[0086]

In the drying and grinding step, since the site of use of the non-tobacco plant serving as the main raw material (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.) is used as a mixture, it is heated, dried and processed into a crushed product of a given size. In this case, the ground product is brought to a moisture content suitable for suspending (dispersing, absorbing and distilling) the aerosol former, water and other components to be added later. Therefore, drying is preferably carried out at a temperature of 60 to 80°C, more preferably 65 to 75°C. By drying the ground product in this temperature range, the desired amount of moisture can be achieved while avoiding dispersion of the desired aroma component. That is, if it is below 60°C, it takes a long time to reach the desired amount of moisture, and if it exceeds 80°C, the necessary aroma component is dissipated. Then, the moisture content of the non-tobacco plant after drying and grinding is preferably set to 0.1 to 5% by mass, more preferably 0.1 to 3% by mass or less. At least a constant amount of water is required because affinity for water or the like is required for suspension. The provision of a screening step for screening the ground product in the drying and grinding step not only further facilitates suspension, but also allows the suspension to be obtained in a preferred state.

[0087]

In the preparation step, aerosol former, microcrystalline cellulose, cross-linked polyvinylpyrrolidone, β-cyclodextrin, thickener, flavoring agent, antibacterial preservative, water, alcohol, etc., which are raw materials other than non-tobacco plant, necessary for the production of aroma-producing substrate 23 of an elongated shape to be heated is weighed and introduced into the mixing stage. As the water in the present embodiment, water obtained by sterilization or removal of microorganisms, pure water obtained by ion exchange or reverse osmosis film, and the like is used.

[0088]

The mixing step is wet mixing. For example, in the mixing step, a conventional wet mixer is preferably used in which the raw material in the mixing tank is mixed with a mixing paddle under shear force, such as a Henschel mixer or the like. In the case of high viscosity, it is preferable to use a Banbury rotor mixer, paddle kneader or the like.

[0089]

In the molding step in the present embodiment, a method for molding and processing a rectangular elongate-shaped aroma-producing substrate 23 to be heated, which is long in the longitudinal direction and is used as a raw material for manufacturing the aroma-producing product to be heated 2, will be described as a representative example. However, the shape of the elongated flavor-producing substrate to be heated is not limited thereto. The molding method described below is also an example and is not limited to this method.

[0090]

First, a mixture in which various raw materials are mixed is formed into a thin sheet in a three-roll mill. The three-roll mill can produce a desired sheet thickness with a doctor blade while kneading and dispersing or the like. due to the compressive force transmitted between the narrow rolls and the shear force due to the difference in the speed of the rolls. A three-roll mill is preferred as a slurry forming processing machine in which various raw materials such as the present invention are dispersed into a sheet. For this finishing, a pressure roll or a press machine can be used. The three-roll mill is capable of not only shaping, but also kneading and dispersing. For this reason, it is also possible to further add a non-tobacco plant, an aerosol former, a binding agent, a fragrance, an antibacterial preservative, water or the like, if necessary, and to form a desired heat-producing fragrance-producing sheet by adjusting the viscosity and mixing amount. As described above, the method of forming and processing into a sheet is not limited to this, and it is also preferable to use the method of forming a slurry by passing through a pressure hole.

[0091]

The thickness of the heated aroma producing sheet to be molded in the molding step is preferably in the range of 0.1 to 1.0 mm, more preferably in the range of 0.1 to 0.5 mm.

[0092]

The heat-produced aroma-producing sheet thus prepared is cut to a predetermined width by a cutter, rotary knife cutter or the like. in the slicing step, and an elongated flavor-producing substrate 23 to be heated is obtained.

[0093]

In the present embodiment, cutting of a 0.3 mm thick heated aroma-producing sheet will be described as an example. First, the formed heated aroma-producing sheet is cut into a rectangle having a length of 150 mm and a width of 240 mm. The rectangular heated aroma-producing sheet is fed to a rotary cutter to obtain a sheet-cut material having a shape of 1.5 mm in length and 240 mm in width, that is, an elongated-shaped aroma-producing substrate 23 to be heated supplied for the production of aroma-producing article 21, to be heated. An elongated flavor-producing substrate 23 to be heated is shown in FIG. 3(B). In this case, the length X of the short axis of the cross-section perpendicular to the longitudinal direction of the elongate-shaped aroma-producing substrate 23 to be heated is 0.3 mm, the length Y of the long axis is 1.5 mm, and the length Z in the longitudinal direction is 240 mm. The ratio of long axis length to short axis length in the elongate-shaped aroma-producing substrate 23 is Y:X=5:1, and the lengthwise to short axis length ratio is Z:X=800:1.

[0094]

However, the elongate-shaped aroma-producing substrate 23 to be heated is not limited to the substantially rectangular shape shown in FIG. 3(B). The perpendicular cross section of the elongated flavor-producing substrate 23 to be heated may be substantially square, that is, the ratio between the short axis length and the long axis length may be 1:1.

[0095]

As shown in FIG. 4(A) and 4(B), it is also possible to use an elongated flavor-producing substrate 23 to be heated having a circular cross section and an elliptical cross section, respectively. However, in the case of such a shape, a heated aroma producing sheet can be used and produced by extrusion molding using a round die and an elliptical die, as well as an extruded elongate forming machine or the like.

[0096]

As shown in FIG. 5, fifty heat-producing aroma-producing articles 23 of an elongated shape having the shape shown in FIG. 3(B) and having Y:X=5:1 and Z:X=800:1 were used to manufacture the aroma-producing article 21 to be heated provided in the aroma cartridge 1 as shown in FIG. one.

[0097]

A flowchart of a method for manufacturing a fragrance-producing article to be heated 21 using such an elongated-shaped fragrance-producing article 23 to be heated, and a manufacturing apparatus, are schematically shown in FIG. 6. This method and apparatus for manufacturing a fragrance-producing article to be heated 21 by arranging an aroma-producing substrate 23 of an elongated shape to be heated, which is formed by cutting a heated fragrance-producing sheet in the longitudinal direction of a packaging material web of the fragrance-producing article to be heated 712, continuously wrapping the flavor-producing substrate 23 of an elongated shape to be heated, and cutting the wrapped rod-shaped flavor-producing article 25 to be heated.

[0098]

The aroma-generating substrate 23 of an elongated shape to be heated, formed by cutting a heat-producing aroma-producing sheet, was placed on the conveyor 81 of the supply unit 8 of the flavor-producing substrate of an elongated shape to be heated, so that the longitudinal direction of the aroma-producing substrate 23 of an elongated shape to be heated is and the direction of movement of the conveyor 81 were parallel to each other. In this case, through the conveyor 81 and the conveying device of the elongated aroma-producing substrate 82 to be heated, the aroma-producing substrate 23 of the elongated shape to be heated is transferred to the packaging material web of the aroma-producing product to be heated 712 in the receiving module of the aroma-producing substrate 730 of the elongated shape to be heated of the wrapping module 7 so that the longitudinal direction of the packaging material web of the aroma-producing article to be heated 712 supplied from the packaging material of the aroma-producing article to be heated supply module 71 becomes parallel to the longitudinal direction of the aroma-producing substrate 23 of the elongated shape to be heated. heating. The web of packaging material of the flavor-producing article 712 to be heated is supported and transported by an endless stringer belt 721 supplied from the stringer belt supply unit 72. Thus, the aroma-producing substrate 23 of an elongated shape to be heated, which is placed on the packaging material web of the aroma-producing article 712 to be heated, and supported and transported by the stringer belt 721, passes through the wrapping guides (1) to (4) which are included in a groove in which the stringer tape 721 is bent in a direction perpendicular to the conveyance direction together with the heated aromatic biogenic packaging material web 712. The aroma-producing substrate 23 of an elongated shape to be heated is wrapped to form a cylindrical, rod-shaped aroma-producing article 25 to be heated. The cylindrical rod-shaped aroma-producing article 25 to be heated is cut to a predetermined length by the cutting module 9, and the aroma-producing article 2 to be heated is manufactured. The method of linearly gluing the packaging material of the rod-shaped flavor-producing article 25 to be heated in the transport direction is performed by first applying a hot-melt adhesive to a predetermined position of the packaging material web of the aroma-producing article to be heated 712, wrapping it, and then passing it through the heating and gluing module 74.

[0099]

Filling structure of the aroma-producing substrate 21 to be heated inside the aroma-producing article 2 to be heated packed in the packaging material of the aroma-producing article to be heated 22, which is thus manufactured, that is, a deformed gas flow path, is formed by passing a web of packaging material aroma-producing article 712 to be heated, on which the aroma-producing substrate 23 of an elongated shape to be heated, together with the stringer tape 721, is placed through the wrapping guides (1) 731 to (4) 734, which are installed in the wrapping module 7 and have different depths grooves.

[0100]

In FIG. 6(A) to 6(E) show a state in which a deformed gas flow path of the aroma-producing substrate to be heated 21 is formed inside the aroma-producing article to be heated 2 packaged in the packaging material of the aroma-producing article to be heated 22. The wrapping guides (1) 731 to (4) 734 are shaped in a cross section perpendicular to the conveying direction, and the groove depth becomes larger. The aroma-producing substrate 23 of an elongated shape to be heated is completely wrapped in the wrapping guide (4) 731 in accordance with the direction of transport.

[0101]

In FIG. 6(A) shows the state in which the flavor-producing stretched-shaped substrate 23 to be heated is conveyed from the conveyor 81 by the transport device for the flavor-producing stretched-shaped substrate 82 to be heated to the wrapping web of the stretched-shaped flavor-producing product 712 to be heated. , the receiving module of the aroma-producing substrate 730 of an elongated shape to be heated of the wrapping module 7, so that the longitudinal direction of the packaging material web of the aroma-producing product to be heated 712 supplied from the packaging material of the aroma-producing product to be heated supply module 71 becomes parallel to the longitudinal direction an elongated flavor-producing substrate 23 to be heated. In fact, although not clearly shown in FIG. 6(A), an elongate-shaped aroma-producing substrate 23 to be heated is stacked in a substantially aligned manner.

[0102]

In FIG. 6(B) shows a state in which the aroma-producing substrate 23 of an elongated shape to be heated passes through the wrapping guide (1) 731 having a shallow crescent-like groove. When the flavor-producing substrate 23 of an elongated shape to be heated, which is aligned and stacked on the packaging material web of the flavor-producing product 712 to be heated, passes through the groove along with the stringer tape 721, the stringer tape 721 and the packaging material web of the aroma-producing product 712, to be heated is bent along the groove in a direction perpendicular to the conveying direction, the primary fill 232 of the elongated flavor-producing substrate to be heated is formed so that the elongate-shaped flavor-producing substrate 23 to be heated is compressed and a flow channel begins to form. a gas formed by the primary filler of an elongated flavor-producing substrate to be heated.

[0103]

In FIG. 6(C) shows a state in which an elongate-shaped aroma-producing substrate 23 to be heated passes through a groove wrapping guide (2) 732 having a depth of about half a moon disc. The stringer belt 721 and the web of packaging material of the aroma-producing article 712 to be heated are substantially curved along the grooves in the direction perpendicular to the conveyance direction, and elongate-shaped aroma-producing substrate primary fillers 232 are successively formed. Each of them is formed by a number of gas flow channels formed by primary fillings of an elongated flavor-producing substrate 233 to be heated. At the same time, pairs of primary fillers 232 of the elongate-shaped aroma-producing substrate to be heated, or the primary filler of the elongated-shaped aroma-producing substrate 232 to be heated, and the single product 231 of the elongated-shaped aroma-producing substrate to be heated, etc., form a secondary a filler 234 of an elongated shape of the flavor-producing substrate to be heated. A large gas flow path formed by the secondary fill 235 of the elongate shaped aroma-producing substrate to be heated begins to form between the primary fill 232 of the elongate-shaped aroma-producing substrate to be heated and between the primary fill 232 of the aroma-producing substrate to be heated and the single product. 231 aroma-producing substrate of an elongated shape to be heated. In the outer peripheral region, the gas flow path formed by the packaging material web 241 of the aroma-producing article to be heated is also formed between the single product 231 of the elongate-shaped aroma-producing substrate to be heated and the primary fill 232 of the elongate-shaped aroma-producing substrate to be heated, and web 712 of packaging material producing flavor of the article to be heated.

[0104]

In addition, as shown in FIG. 6(D), when the aroma-producing substrate 23 of an elongated shape to be heated passes through the nearly full moon-shaped groove wrapping guide (3) 733, the state shown in FIG. 6(C) progresses so that the stringer belt 721 and the packaging material web 712 of the flavor-producing article to be heated form a circle in the direction perpendicular to the conveying direction along the groove. In its outer circumferential region, the aroma-producing elongate-shaped substrate 23 to be heated, constituting the primary filler 232 of the elongate-shaped aroma-producing substrate to be heated, and the secondary filler 234 of the elongate-shaped aroma-producing substrate to be heated, moves while sliding. As the frequency with which the surface in the long axis direction in the cross section perpendicular to the elongated flavor-producing substrate 23 to be heated is increased with the surface in the long-axis direction in the perpendicular cross section of the adjacent flavor-producing elongate shape substrate 23 to be heated, the amount of the elongate-shaped flavor-producing substrates 23 to be heated, in which the long axis direction is tangential to the circumference, also increases, and the filling degree of the elongated-shaped aroma-producing substrate 23 to be heated in the outer peripheral region starts to increase. On the other hand, the primary fill 232 of the elongate-shaped aroma-producing substrate to be heated and the secondary fill 234 of the elongate-shaped aroma-producing substrate to be heated remain in the central region. Therefore, the gas flow path formed by the elongated flavor-producing substrate primary fill 233 and the gas flow path formed by the elongate-shaped flavor-producing substrate secondary fill 235 are not greatly reduced, and the number of voids starts to become larger than in the outer periphery.

[0105]

Then, as shown in FIG. 6(E), the stringer belt 721 and the packaging material web 712 of the flavor-producing article to be heated are completely wrapped along the grooves in the direction perpendicular to the conveyance direction, and the rod-shaped flavor-producing article 25 to be heated is formed. In this state, the state shown in FIG. 6(D) progresses and the internal structure of the rod-shaped aroma-producing article 25 to be heated is fixed. That is, in the central region of the rod-shaped aroma-producing article 25 to be heated, a volumetric primary filler 232 of an elongated shape of the aroma-producing substrate to be heated, and a secondary filler 234 of the aroma-producing substrate to be heated, and a gas flow channel formed by the primary filler 233 remain. of an elongate-shaped, heated aroma-producing substrate, and a gas flow path formed by the secondary filler 235 of an elongated-shaped aroma-producing substrate to be heated, formed therein have a high porosity, and a deformed gas flow path is created. On the other hand, the outer peripheral region also defines a gas flow path formed by the packaging material web 241 of the aroma-producing article to be heated between the single product 231 of the aroma-producing substrate material of elongated shape and the primary filler 232 of the aroma-producing substrate of elongated shape and the web 712 of packaging material. aroma-producing article to be heated. However, the elongate-shaped aroma-producing substrate 23 constituting the elongated-shaped aroma-producing substrate material primary fill 232 and the elongated-shaped aroma-producing substrate material secondary fill 234 to be heated move while sliding. Therefore, as the contact frequency increases between the surface in the long axis direction of the cross section perpendicular to the elongated flavor-producing substrate 23 to be heated and the surface in the long axis direction of the perpendicular cross-section of the adjacent flavor-producing elongate shape substrate 23 to be heated, the amount of the elongate-shaped flavor-producing substrates 23 to be heated, in which the long-axis direction is located in the circumferential tangential direction, is also large, and the filling degree of the elongated-shaped aroma-producing substrate 23 to be heated in the outer peripheral region is increased. Thus, a stable and durable structure is formed.

[0106]

The internal structure of the rod-shaped aroma-producing article 25 to be heated is a structure with a cross-section perpendicular to its longitudinal direction and a cross-section perpendicular to the longitudinal direction of the elongate-shaped aroma-producing substrate 23 to be heated is formed uniformly in the longitudinal direction, so that the structure in cross-section perpendicular to the longitudinal direction of the rod-shaped flavor-producing article 25 to be heated is uniform, and deformed gas flow channels, such as the gas flow channel formed by the primary fill 233 of the elongate-shaped aroma-producing substrate to be heated, the gas flow channel formed by the secondary assembly 235 of the aroma-producing substrate of an elongated shape, and the gas flow path formed by the packaging material web 241 of the aroma-producing article to be heated extends in the longitudinal direction a rod-shaped aroma-producing article 25 to be heated. Accordingly, the internal structures of the aroma-producing article 2 to be heated obtained by cutting the rod-shaped aroma-producing article 25 to be heated and the rod-shaped aroma-producing article to be heated 25 are the same.

[0107]

In FIG. 7 shows an enlarged cross-sectional view perpendicular to the longitudinal direction of the flavor-producing article 2 to be heated. This is exactly the same as the sectional view of FIG. 6(E), and has the same structure. Accordingly, when smoking is performed using the flavor cartridge 1 provided with the flavor-producing article 2 to be heated, the problem of the conventional flavor cartridge is eliminated, and the smoke and flavor of the aerosol can be sufficiently drawn into the smoker's mouth so that comfortable smoking can be achieved. In addition, the filling degree of the aroma-producing substrate to be heated in the outer peripheral region is higher than that in the central region, thereby forming a strong structure against pressure from the end portion and the outer peripheral portion of the aroma-producing article to be heated. Therefore, the aroma-producing substrate to be heated does not fall out when the aroma cartridge is attached/disconnected, and an appropriate number of puffs per piece of tobacco is provided, and there is no problem of the aroma-producing substrate to be heated being ignited during puffing. In addition, the lower filling ratio in the central region facilitates insertion of the aroma cartridge into the heating element of the heated aroma device.
