There is also a limit to the amount of liquid that can be contained in the tobacco medium.

In addition to the cigarette containing the cigarette medium, a liquid is stored in a separate atomizer to generate additional aerosol, so that when the user inhales the cigarette, the aerosol derived from the liquid is inhaled through the cigarette (so-called'hybrid type') However, it is difficult to manage the liquid contained in the cartomizer (expiration date, deterioration, etc.), and condensation may occur due to condensation in the airflow path through which the aerosol generated in the cartomizer moves.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

Hereinafter, a gel-type aerosol-generating cartridge that can be inserted into an electrically heated smoking article capable of generating an aerosol by heating according to a preferred embodiment of the present invention, and an electrically-heated smoking comprising such a gel-type aerosol-generating cartridge The article will be described with reference to the accompanying drawings, and for convenience of description, each of the components of the electrically heated smoking article will be described, and the gel aerosol-generating cartridge included therein will be described. Here, the electric heating type smoking article refers to a form in which an aerosol is generated from a smoking article and the user inhales and uses the aerosol by heating the smoking article by an electric resistance heating method or an induction heating method. Such a smoking article contains an appropriate amount of aerosol-generating substrate and/or tobacco sheath inside the smoking article to perform a similar number of inhalation acts as one cigarette cigarette, and after the aerosol is generated by a predetermined amount, it is no longer It does not generate an aerosol and will be discarded by the user after one use.

The electrically heated smoking article according to the present invention is an aerosol-generating substrate and includes a gel-like aerosol-generating substrate comprising a liquid composition, such as conventional tobacco kerosene and glycerin, as described below. An electrically heated smoking article 50 according to one preferred embodiment of the present invention includes a tobacco body 58 containing tobacco cuttlefish as an aerosol-generating substrate at an upstream end, and a liquid composition as another aerosol-generating substrate immediately below it The gel-like aerosol-generating substrate (56) has a structure in which a paper tube (54) providing an aerosol movement passage immediately downstream thereof and a filter (52) functioning as a mouthpiece are stacked, and they are attached to the wrapping paper (60). Wrapped by. The relative positions of the gel-like aerosol-generating cartridge 56 by the liquid composition and the tobacco body 58 by tobacco cuts may be reversed.

The gel-like aerosol-generating substrate cartridge according to the present invention exists as a gel, semi-solid or solid phase (hereinafter, also simply referred to as'gel phase') in a first temperature range (eg, a temperature range of 50° C.) including room temperature. And a liquid aerosol in a second temperature range including 70° C. (for example, a temperature range of 50-100° C.) and vaporizing with an aerosol in a temperature range of 150 to 400° C., a gel aerosol containing glycerin and gelatin. Development substrate; A gel receptor 56a in which a gel-like aerosol-generating substrate is accommodated; And a wrapping paper 61, which wraps the side surfaces of the gel receptor 56a in a cylinder shape having a length of 7 to 20 mm and a diameter of 5 to 8 mm. The cylinder shape having a length of 7 to 20 mm and a diameter of 5 to 8 mm is a size that conforms to the standard of a conventional tobacco or electric heated smoking article currently in use, and a gel aerosol-generating cartridge having such a specification is an electric heated smoking article. When inserted into the 50 and wrapped with a separate wrapping paper 60, from the user's point of view, there is no difference from a conventional cigarette or an electrically heated smoking article.

Tobacco kerosene 58a cannot maintain its shape with only cigarette kerosene, so it is wrapped with a separate wrapping paper 62 to form a cigarette body 58, and has the same size (diameter) as the gel-like aerosol-generating substrate cartridge 56. An electrically heated smoking article as shown in FIG. 1 by wrapping the filter 52, the paper tube 54, the gel-like aerosol-generating cartridge 56, and the tobacco body 58 with the wrapping paper 60 as described above. 50) can be obtained.

Specifically, the gel-like aerosol-generating substrate is a mixture of glycerin and gelatin. For example, glycerin PG (Proplylene Glycol) or VG (Vegetable Glycerine), or PG and VG mixture is heated for 30 minutes and stirred for 30 minutes to lower the viscosity. By adding 10-50% by weight of a possible additive, gelatin and/or water, the mixture is stirred until the additive is dissolved in glycerin, and a mixture of glycerin and gelatin and/or water can be obtained. The mixture maintains a gel, semi-solid, or solid phase in a first temperature range including room temperature (a temperature range of less than about 50° C.) and is heated to a second temperature range including 70° C. (temperature range of 50 to 100° C. In ), it changes to a liquid phase and exists as a liquid phase, and when heated further, generates an aerosol at about 150°C or higher.

As described above, the gel-like aerosol-generating substrate may additionally include one or more of water, agar, thickener, starch powder, celluloses, carboxymethyl ethers, natural food flavors, or fruit extracts. In addition, the content of glycerin in the gel-like aerosol-generating substrate is preferably 50% by weight or more. When water is included, the time to form a gel-like aerosol-generating mixture by reducing the gelatin can be reduced. In addition, the mixture may additionally contain an agar, and in this case also advantageously forms a gel-like aerosol-generating substrate mixture. In addition to this, the gel aerosol-generating substrate mixture may include a thickener, starch powder, celluloses, and carboxymethyl ethers as additives. In addition, the gel-like aerosol-generating substrate mixture may further include natural food flavorings or fruit extracts. In this case, it is possible to add various flavors to the user through the generated aerosol. In any case, the content of glycerin in the gel-like aerosol-generating substrate mixture is preferably 50% by weight or more, thereby minimizing the burnt taste in the aerosol generated. Additionally, the gel-like aerosol-generating mixture may or may not contain nicotine.

Here, the gel aerosol generating substrate, by weight, comprises a liquid composition consisting of 80 to 100% glycerin VG, 0 to 20% glycerin PG, 60 to 80% liquid composition and 20 to 40% water volume It contains gelatin in a weight of 1 to 6 g compared to 100 ml of the mixture mixed in proportion, and optionally includes a flavoring agent added to 10% or less based on the total weight of the liquid composition. The liquid composition is preferably contained in the amount of 70 to 120 mg in the gel receptor. This numerical range refers to the amount of a liquid composition that can provide aerosols derived from the liquid composition together when a user inhales the aerosol from the tobacco body 58 by tobacco sheath provided in a single ratio of electrically heated smoking articles. When a liquid composition having a lower value (70 mg) or less is included as a gel-like aerosol-generating substrate in the gel receptor 56a, a user may use an aerosol derived from the tobacco body 58 caused by tobacco sheath provided to the electrically heated smoking article. Since the aerosol derived from the liquid composition may be insufficient during the inhalation process, the liquid composition included in the gel aerosol-generating substrate cartridge 56 should be at least the lower limit value (70 mg). When the liquid composition exceeding the upper limit (120 mg) is included in the gel receptor 56a, the volume of the gel aerosol-generating substrate that is a mixture may be too large, so that the gel receptor in the gel aerosol-generating substrate cartridge 56 having the above specification is a liquid composition. It can be difficult to hold. Therefore, the liquid composition included in the gel-like aerosol-generating cartridge should be less than or equal to the upper limit (120 mg). The preferred range is 80 to 110 mg, and the more preferred range is 90 to 105 mg.

Another feature of the present invention is that the gel aerosol-generating substrate may exist or may exist in a liquid state in the manufacturing process as described below. Even if it is liquefied, the gel receptor 56a in the gel-like aerosol-generating substrate cartridge having the above specification is The liquid composition having a compositional range has a sufficient moisture absorption rate to be maintained in the gel-like aerosol-generating cartridge. That is, the liquid composition remains absorbed by the gel receptor 56a in the gel-like aerosol-generating cartridge, and does not flow out of the gel-like aerosol-generating substrate. Here, the moisture absorption indicates that the gel receptor is wet by the liquid composition, but this does not flow out. As described later, the filter 52-the paper tube 54-the gel-like aerosol-generating cartridge 56-the cigarette body 58 is wrapped with a wrapping paper 60 to form an electrically heated smoking article 50, The gel-like aerosol-generating substrate cartridge 56 is in direct contact with the cigarette body 58, the paper tube 54, or the filter 52 without a separate member toward the upstream or downstream sides, and the gel receptor in the gel-like aerosol-generating cartridge 56 The liquid composition absorbed by (56a) is absorbed and stored in the gel receptor and does not flow toward the tobacco body 58 or the paper tube 54 or the filter 52. To this end, the liquid composition is desirably absorbed by the gel receptor in an amount of 0.13 to 0.32 mg/mm ³ per unit volume of the gel receptor. The reason for the numerical limitation is similar to the numerical limitation for the amount of the liquid composition absorbed by the gel receptor 56a of the present invention. That is, when the lower limit value (0.13 mg / mm ³ ) is less, the amount of the liquid composition absorbed by the gel receptor 56a is insufficient, so that the user inhales the aerosol derived from tobacco cuts provided to the electrically heated smoking article. Since the aerosol derived from the gel-like aerosol-generating substrate may be insufficient, the liquid composition absorbed by the gel-like aerosol-generating cartridge should be at least the lower value (0.13 mg/mm ³ ). When the liquid composition exceeding the upper limit (0.32 mg/mm ³ ) is absorbed by the gel receptor, the gel composition in the gel aerosol-generating cartridge having the above specification may be difficult to maintain the liquid composition while absorbing the liquid composition. The liquid composition can flow out of the gel-like aerosol-generating cartridge 56.

The'gel-like aerosol-generating substrate cartridge' used in the present invention exists as a gel at room temperature and is liquefied in a temperature range of 50 to 100°C, including 70°C, for example, and then, for example, a temperature of about 150 to 350°C through additional heating It refers to a cartridge 56 containing a gel-like aerosol-generating substrate that vaporizes with an aerosol in the range. In one example, the gel-like aerosol-generating substrate is present in the form of a gel in a first temperature range including room temperature, and a liquid phase such as glycerin VG (optionally containing glycerin PG) that changes to a liquid state in a second temperature range including 70°C. It is a gel mixture of the composition, gelatin, and water, and is heated by an electric induction or resistance heating method by a separate aerosol-generating device, so that the gel-like aerosol-generating substrate is changed into a liquid phase, and the liquid composition generates an aerosol through additional heating. According to one preferred embodiment of the present invention, the liquid composition is weight %, 100% glycerin VG, and according to another preferred embodiment, the liquid composition is weight %, 80% glycerin VG, 20% glycerin PG.

According to another preferred embodiment, heat is given to the liquid composition as described above and stirred for 30 minutes to lower the viscosity, and an additive that can be gelled is added to gelatin and/or water, stirred until the additive dissolves in glycerin, and glycerin and It is possible to obtain a gel-like mixture of gelatin and/or water. In this case, 60 to 80% of the liquid composition and 20 to 40% of the volume ratio of water were mixed to contain 1 to 6 g of gelatin compared to 100 ml of the mixture.

According to another preferred embodiment, 1 g, 1.5 g, and 2 g of gelatin are respectively added to 10 ml of cold water to call gelatin, and 50 ml of a liquid composition in which 80% of glycerin VG and 20% of glycerin PG are mixed by weight% is obtained. After mixing and dissolving, it was left at room temperature for 6 hours or more. The gelation proceeded well even when left at room temperature, and the gelation progressed better as the amount of gelatin increased. At 1 g or more and 1.5 g or less of gelatin, the viscosity increased and the gelation was weak.

According to another preferred embodiment, 5 g of gelatin is poured into 50 ml of cold water for 30 minutes, and 100 ml of a liquid composition in which 80% of glycerin VG and 20% of glycerin PG are mixed in weight% is added thereto for 90 minutes at 75°C. It was possible to obtain a gel-like aerosol-generating substrate by stirring and heating.

The gel-like aerosol-generating substrate maintains a gel phase in the first temperature range (below about 50°C) including room temperature, and is heated to change into a liquid phase in the second temperature range (70°C to 100°C) including 70°C. Therefore, when it is present in the liquid phase and is further heated, aerosol is generated at about 120°C or higher. As described below, in order to inject the gel-like aerosol-generating substrate into the gel receptor 56a, during the manufacturing process, the gel-like aerosol-generating substrate is heated to a second temperature range to liquefy, and the liquid is sprayed onto the gel receptor 56a or by a needle or the like. The liquid is absorbed into the gel receptor 56a by injection. Thereafter, the liquid is kept at a low temperature, for example, at about 4° C. for 5 to 10 minutes, or at room temperature for 1 hour or more, so that the liquid absorbed by the gel receptor 56a is changed into a gel, and the surface and pores in the gel receptor 56a , It becomes a shape in which fine grains are dispersed in a network or the like.

On the other hand, since the gel receptor has sufficient hygroscopicity to the liquid composition of the liquefied aerosol-generating substrate, the liquid composition does not flow out from the gel receptor. As described above, the gel-like aerosol-generating substrate is mainly composed of glycerin and gelatin, but it is preferable to further include water. When water is included, it is possible to reduce the time to form the gel-like aerosol-generating substrate by softening the gelatin. In addition, the gel-like aerosol-generating substrate may additionally include an agar, and in this case also advantageously forms a gel phase. In addition to this, the gel-like aerosol-generating substrate may include a thickener, starch powder, celluloses, and carboxymethyl ethers as additives. In addition, the gel-like aerosol-generating substrate may further include natural food flavorings or fruit extracts. In this case, it is possible to add various flavors to the user through the generated aerosol. In either case, the content of glycerin in the gel-like aerosol-generating substrate is preferably 50% by weight or more, thereby minimizing the burnt taste in the aerosol generated.

As described above, the liquid composition comprises 80% to 100% of glycerin VG, and 0 to 20% of glycerin PG in weight%, and further includes a flavoring agent added to 10% or less based on the total weight of the liquid composition thus obtained. Includes. According to one preferred embodiment, the present invention uses a liquid composition consisting of 100% glycerin VG by weight. According to another preferred embodiment, the present invention uses a liquid composition consisting of 80% glycerin VG and 20% glycerin PG by weight. According to another preferred embodiment, the present invention further comprises a flavoring agent added to 10% or less based on the total weight of the liquid composition thus obtained. For example, flavoring agents are licorice, sucrose, fructose syrup, isosweetener, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon Oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee. In addition, the liquid composition may or may not contain nicotine.

According to the present invention, gel receptors 56a of various materials can be applied. According to FIGS. 1 and 2, the gel receptor 56a is illustrated as being rolled up, but this is expressed for convenience of illustration, and is not limited to the configuration of the gel receptor 56a. Several types of gel receptors 56a may be considered as follows, and basically, the gel receptors 56a are bent or rolled to one side of the pipe structure 40 shown in FIG. 3, and the cross section is somewhat narrowed from the other side. The gel receptor rod 57 can be obtained by wrapping with wrapping paper 61 while extruding. Before being introduced into the pipe structure 40, the liquefied gel aerosol-generating substrate is absorbed into the gel receptor 56a through a liquid injection part such as a needle, and the gel receptor 56a passes through the pipe structure 40 to generate a liquefied gel aerosol. The substrate is wetted or immersed, and is immediately wrapped by the wrapping paper 61 on the other side of the pipe structure 40 to be cut to a suitable length, for example, about 80 mm or 140 mm to form the gel receptor rod 57. That is, the gel-like aerosol-generating substrate mixture is heated to a second temperature range including 70° C. to make it a liquid state, and is injected into the gel receptor 56a through an injection portion such as a needle to be absorbed by the gel receptor 56a. It may be subjected to an appropriate cooling process before cutting with the gel receptor rod 57, and since the gel receptor 56a has sufficient hygroscopicity against the liquid phase gel-like aerosol-generating substrate, an appropriate time at room temperature after cutting, for example, 1 hour To maintain or to maintain a low temperature, for example, 5 to 10 minutes at 4° C., the gel-like aerosol-generating substrate in the liquid state introduced into the gel receptor 56a is gelated and subsequently processed (cutting with a cartridge or wrapping with a smoking article) During operation), the liquid composition can be prevented from being minimized or minimized from flowing out from the gel receptor 56a. That is, the gel receptor rod 57 may be provided in a state in which the gel aerosol-generating substrate is wrapped in a liquid state with the gel receptor 56a wrapped with the wrapping paper 61, and the gel receptor may be provided by providing an appropriate cooling structure to the pipe structure. The rod 57 may be wrapped with the wrapping paper 61 while the gel-like aerosol-generating substrate is present in the gel receptor 56a in a gel form. Alternatively, the gel receptor rod 57 can be held by gelling a mixture containing an aerosol-generating substrate introduced into the gel receptor by simply maintaining it in a first temperature range including room temperature for a predetermined time as described above. As it is cut to a size that can fit into the individual smoking article 50.

This configuration is a generalized process in the existing cigarette manufacturing line, and has the advantage of using the existing cigarette manufacturing process and equipment as it is. In other words, the above process is applied as it is in the manufacture of conventional filters, paper tubes, and tobacco kerosene, and the cartridge 56 can be obtained using such current equipment and processes.

The gel-like aerosol-generating substrate is introduced into the gel receptor in a liquid state in a second temperature range of 50 to 100°C, for example, including 70°C, so that it can be easily absorbed into the gel receptor, which will be described later. In the first temperature range of less than 50°C, the gel receptor is present in the gel phase in the space between the surfaces, pores, and networks present in the gel receptor. Therefore, when the gel-like aerosol-generating cartridge is maintained in the first temperature range including room temperature, the possibility that the liquid composition contained in the gel-like aerosol-generating substrate flows out or leaks from the gel-like aerosol cartridge is minimized.

So as to be wrapped in a cylinder shape. Accordingly, the aluminum foil may eliminate or minimize the possibility that the gel-like aerosol-generating substrate in the liquid state contained in the gel receptor 56a flows through the side of the gel-like aerosol-generating cartridge 56. That is, as can be seen from the configuration of the gel-like aerosol-generating substrate shown in FIGS. 1 and 2, the gel receptor 56a is a separate wrapping paper 61 before being wrapped by the wrapping paper 60 for forming a smoking article. Wrapped by, in this case, the wrapping paper 61 may be provided in the form of aluminum foil attached to the paper, it is preferable that the aluminum foil is wrapped in a cylindrical shape to contact the gel receptor 56a.

The tobacco body 58 may include a solid material based on tobacco raw materials such as plate-shaped tobacco, cut filler, and reconstituted tobacco. In one embodiment, the cigarette body 58 may be filled with a corrugated plate leaf sheet. The leaflet sheet may be wrinkled by being curled, folded, compressed, or shrunk substantially in the horizontal direction of the cylinder axis. Porosity can be determined by adjusting the bone spacing, etc., of the corrugated leaf lobe sheet.

In another embodiment, the tobacco body 58 may be filled with tobacco cuts. Here, tobacco cuts can be produced by finely cutting the tobacco sheet (or slurry leaflet sheet). In addition, the cigarette body 58 may be formed by a plurality of tobacco strands in the same direction (parallel) or randomly combined. Specifically, the tobacco body 58 is formed by combining a plurality of tobacco strands, and a plurality of channels in the longitudinal direction through which the aerosol can pass may be formed. At this time, depending on the size and arrangement of the tobacco strands, the longitudinal channels may be uniform or non-uniform.

The tobacco body 58 may further include at least one of ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the tobacco body may further include glycerin and propylene glycol.

In addition, the tobacco body 58 may contain other additives such as flavoring agents and/or organic acids. For example, flavoring agents are licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, Vanilla, lemon oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee. Meanwhile, the tobacco medium accommodating parts 11a and 11b may partially include glycerin or propylene glycol.

In some cases, the liquid composition may contain nicotine without a tobacco body made of tobacco kerosene, and a tube and a filter may be sequentially stacked in a gel-like aerosol-generating cartridge and wrapped with wrapping paper to produce an electrically heated smoking article.

The electrically heated smoking article 50 according to the present invention may include a paper tube 54 that provides an aerosol moving passage, as shown in FIGS. 1 and 2, in which a PLA is inserted into the tube to control the temperature of the aerosol. It can also be lowered to prevent the user from being burned when inhaling the aerosol. The paper tube 54 can also be wrapped by a separate wrapping paper (not shown). In this case, the wrapping paper for the paper tube 54 is sufficient with paper, that is, paper.

The filter 52 serving as a mouthpiece serves to prevent the aerosol passing and the liquid inflow as shown in FIGS. 1 and 2. As described above, the gel-like aerosol-generating substrate held in the gel receptor 56a is maintained in the gel receptor 56a in a gel form or the like in a first temperature range including room temperature, but the surrounding environment in which smoking articles are stored is at a second temperature. Some liquid compositions may flow out in an abnormal environment, such as when it reaches a range or when an excessive external force acts only on the gel-like aerosol-generating cartridge 56 in this situation, in which case the filter serves to prevent the liquid from entering. Perform (paper tubes can function similarly). The filter can be made of pulp, and can be made in the form of a cylinder or tube. On the other hand, the filter can improve the user's satisfaction by including a flavor component. Flavoring ingredients include, for example, licorice, sucrose, fructose syrup, isosweetener, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon Oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander or coffee.

Essentially, the above-described gel-like aerosol-generating cartridge 56 may be made using the same process and equipment for incorporating flavor components in the filter 52 as above. In this case, existing processes and equipment are used as they are, so there is no great difficulty in meeting mass production and quality control.

The electrically heated smoking article 50 is usually wrapped with a plurality of layers of lapping

papers

60, 61, and 62, the first lapping paper 61 surrounding the portion where the gel aerosol-generating substrate is located, the gel aerosol downstream or upstream A second wrapping paper 62 that wraps the generator substrate cartridge and the tobacco body by tobacco keratin together, a third wrapping paper that wraps the tube together thereon (not shown), over which all parts of the electrically heated smoking article are wrapped. Like the fourth wrapping paper 60, it can be wrapped with multiple layers of wrapping paper. The electric heating type smoking article may be obtained through various steps of lapping, and in some cases, a process of forming a gel-like aerosol-generating cartridge may be performed separately or may be performed through a continuous line.

Alternatively, to reduce manufacturing time and to reduce manufacturing costs, wrap the padding of different materials or different thicknesses on the inside of the outermost wrapping paper wrapping all parts of the electrically heated smoking article. It is also possible to do.

1 and 2, the gel-type aerosol-generating cartridge 56 according to an embodiment of the present invention wraps the gel receptor 56a containing the gel-like aerosol-generating substrate containing a liquid composition as a housing The paper 61 is wrapping. In addition, a paper tube 54 and a filter 52 are sequentially stacked at the downstream end of the gel-like aerosol-generating cartridge 56. The filter and tube are wrapped by a wrapping paper 60 with a gel-like aerosol-generating cartridge.

The gel aerosol-generating substrate in the gel-like aerosol-generating cartridge 56 is maintained in a gel-like aerosol-generating substrate cartridge 56 in the form of a gel at a gel receptor in a first temperature range, and a liquid composition contained in the gel-like aerosol-generating substrate is a gel-like aerosol-generating substrate It does not flow out of the cartridge 56, but is vaporized by heating and generates an aerosol.

The wrapping paper (60, 61, 62) is preferably made of a material that is not deformed by contact with high heat and liquid or does not generate harmful components to the human body. Alternatively, the wrapping paper may be made of a metal thin film or a metal foil, or may be in the form of a metal thin film or a thin metal sheet overlaid or laminated to a paper-like wrapping paper as described above. According to a preferred embodiment of the present invention, the wrapping paper 61 serving as a housing for the gel-like aerosol-generating cartridge 56 is composed of a lamination of paper and aluminum foil, and the aluminum foil is in contact with the gel receptor 56a. When the gel receptor 56a is placed in the second temperature range during the manufacturing process or during storage, the gel aerosol-generating substrate is changed to a liquid state, thereby preventing the gel-like aerosol-generating substrate 56 from flowing to the side.

The filter 52 on the downstream side of the gel-like aerosol-generating substrate cartridge may have a hollow portion for airflow formation, but a filter having no hollow portion may be used. The filter may be composed of at least one segment, and may include, for example, at least one of a tube filter, a cooling structure, and a recess filter. The tube filter has a shape including a hollow inside. The tube filter and recess filter can be made of cellulose acetate, and the tube serving as a cooling structure can be made of pure polylactic acid or a combination of other degradable polymers and polylactic acid.

More specifically, the filter 52 may be made of a material such as acetate, paper, or PP, and the filter wrapper (wrapping paper) surrounding the filter is made of plain paper, perforated paper, perforated paper, NWA (Non Wrapped Acetate), etc. Can be classified. In addition, the shape of the filter can be classified into a mono filter consisting of one segment and a composite (double, triple, etc.) filter consisting of several segments. The filter may be made of acetate tow, plasticizer, activated carbon, X-DNA, paper. Acetate tow refers to an aggregate of continuous filaments of cellulose acetate, and plays a decisive role in determining suction resistance, the most important characteristic of a filter. The properties of acetate tow are determined by Denia.

The plasticizer softens and softens the cellulose acetate fibers to form bonds at the contact points between the fibers, making the fiber bundles more rigid. Triacetin is used as a plasticizer for cigarette filters.

Activated carbon, which is one of the adsorbents, is a substance mainly composed of carbon, and can be classified according to particle size and properties. Raw materials used for activated carbon are vegetable raw materials, such as wood, sawdust, and fruit flakes (palm shell, bamboo, peach seeds).

X-DNA refers to functional particles processed after being extracted from seaweeds and concentrated. Compared to activated carbon, which is mainly used for cigarette filters, it does not affect the taste of cigarettes, and it has excellent removal function of various carcinogens.

The function of the wrapping paper (wrapping paper) maintains the shape of the filter floc when the filter is manufactured. In the manufacture of the winding paper, properties such as porosity, tensile strength, elongation, thickness, and pasteability must be satisfied.

For example, the length of the gel-like aerosol-generating cartridge 56 is 14.0 mm, the length of the filter 52 or the tube 54 is 2.5 mm each, and the length of the cigarette body 58 including tobacco cuts is 9.0 mm. Can. Alternatively, for example, the filter 52 may be 10 mm, the paper tube 54 may be 16 mm, the gel aerosol-generating cartridge 56 may be 10 mm, and the cigarette body 58 may be 12 mm.

The relative lengths of the filter 52, the paper tube 54, the gel-like aerosol-generating cartridge 56, and the tobacco body 58 and the relative arrangement of the gel-like aerosol-generating cartridge 56 and the tobacco body 58 are described later. It may be related to the temperature of the aerosol in the process of the user inhaling the aerosol generated in the electrically heated smoking article by the aerosol-generating device 100. The temperature of the aerosol generated from the gel-like aerosol-generating substrate cartridge 56 is different from the temperature of the aerosol generated from the cigarette body 58, and as the length of the paper tube 54 increases, the high-temperature aerosol can be further cooled. Therefore, considering the temperature of the aerosol generated from the gel-like aerosol-generating cartridge 56 and the tobacco body 58 and the relative arrangement of the gel-like aerosol-generating cartridge 56 and the tobacco body 58, the gel-like aerosol-generating substrate cartridge The relative length and arrangement of the liquid composition and the amount of tobacco cuts depending on the volume of the 56 and the cigarette body 58 and the heating method of the aerosol-generating device described later may be changed. It will not be difficult for a person having ordinary skill in the art to meet the above various conditions while manufacturing an electrically heated smoking article in the same size as the size of a commercially available electrically heated smoking article.

As described above, according to an exemplary embodiment for manufacturing the gel-like aerosol-generating substrate 56 shown in FIG. 3, first, the gel-like aerosol-generating substrate is heated to a second temperature range to make a liquid, and then the pipe structure 40 ) Before the gel receptor 56a formed in a cylinder shape is introduced into the pipe structure 40, passes through a liquid injection part such as a spray equipment or a needle, and the liquid is sufficiently sprayed or injected to provide the liquid into the gel receptor 56a. The gel receptor 56a passes through the pipe structure 40 and either retains the liquid or becomes wet by the liquid. Thereafter, the liquid-absorbed gel receptor is wrapped with a wrapping paper of, for example, paper (or aluminum foil-laminated paper), cut into necessary lengths (eg 140 mm, 100 mm or 80 mm) and gelled. The receptor rod 57 is formed. The gel receptor rod 57 is cut into a gel aerosol-generating cartridge 56 of a desired length (e.g., 14 mm, 10 mm, 8 mm), as described below, followed by segments of other electrically heated smoking articles (tubes, filters) , Tobacco body) can be made of an electrically heated smoking article 50 for aerosol generation by packing (wrapping) together. As described above, the liquid introduced into the gel receptor 56a passes through the pipe structure 40 or is stored after being cut with the gel receptor rod 57, or after the cutting end with the gel-like aerosol-generating cartridge 56 As it is stored, it is gelled while being maintained in the first temperature range, and is dispersed in the form of fine grains on the surface, pores, and networks inside the gel receptor 56a.

4 is a view schematically showing a cutting process of cutting the gel receptor rod 57 to produce a gel-like aerosol-generating substrate 56 according to another preferred embodiment of the present invention. As described above, for example, the gel receptor rod 57 having a length of 140 mm, 100 mm, or 80 mm flows into the groove of the index table 70 and moves to the conveyor belt 90 according to the rotation of the index table. At this time, a rotary blade 80 is disposed on a path that moves along the index table 70, and the gel receptor rod 57 is 10 by a desired length, for example, 14 mm, 10 mm, or 80 mm by the rotating blade. It is cut into two gel-like aerosol-generating cartridges 56. 10 rotating blades 80 are arranged at equal intervals, cutting the 140 mm gel receptor rod 57 into 10 14 mm gel-like aerosol-generating cartridges 56, or cutting 100 mm gel receptor rod 57 The 10 mm gel-like aerosol-generating cartridge 56 may be cut, or the 80 mm gel-receiving rod 57 may be cut into ten 8 mm gel-like aerosol-generating cartridges 56. As described above, the above process and equipment are used as they are in the case of incorporating a flavoring component or the like in a filter in conventional cigarette manufacturing, so there is no great difficulty in satisfying mass production and quality control.

According to one preferred embodiment of the present invention, a filter 52 functioning as a mouthpiece is located at the downstream end of the gel aerosol-generating substrate 56, and the tobacco agar is included in the upstream end of the gel-like aerosol-generating cartridge 56. The cigarette body 58 is located. Each of these segments (filter, gel-like aerosol-generating cartridge, tobacco body) can be packed together to produce an electrically heated smoking article for generating aerosols. As described above, between the filter 52 and the gel-like aerosol-generating substrate 56, a tube 54 providing a moving passage of the aerosol may be positioned, if necessary. Each of these segments, filters, tubes, liquid cartridges, and tobacco bodies are arranged side by side and packed together to obtain an electrically heated smoking article 50 for aerosol generation. In an actual manufacturing line, these can be arranged in a set of 10 or more in parallel and then cut into several electrically heated smoking articles after lapping is performed.

In any case, the liquid composition that is the aerosol-generating substrate contained in the gel-like aerosol-generating cartridge 56 is gelled and dispersed in fine grains on the surface, pores, networks, etc. of the gel receptor in the gel-like aerosol-generating cartridge, even if it is liquefied. Since it is absorbed by the gel receptor 56a, it does not flow out of the gel-like aerosol-generating substrate cartridge, but because of the high temperature or physical pressure applied to the gel-like aerosol-generating cartridge during the process of manufacturing the electrically heated smoking article or after completing the electrically heated smoking article. It is possible to consider the case where the composition flows out or vaporizes with aerosol and comes out. First, according to a preferred embodiment of the present invention, since the filter is positioned downstream of the gel-like aerosol-generating cartridge, the filter body is located downstream of the gel-like aerosol-generating cartridge, so that a high temperature is applied to the gel-like aerosol-generating cartridge or physical pressure is applied from the outside. Even if it does, it is unlikely that the liquid composition will flow out through the filter or tobacco body. The gel-like aerosol-generating substrate is liquefied in a second temperature range including 70°C, and the liquid composition starts to generate aerosol at about 120°C or higher, so the process control in lapping or manufacturing process of the gel-like aerosol-generating cartridge is 100°C or lower, The loss of the liquid composition during the manufacturing process can be prevented by setting it to the first temperature range of preferably less than 50°C. Inevitably, if a high temperature above the starting temperature of vaporization of the liquid composition is required in the manufacturing process, the amount of the liquid composition lost during the process is estimated, and the amount expected to be lost is added to the required amount, and the liquid composition can be additionally absorbed and managed. have.

Hereinafter, embodiments of the aerosol-generating device 100 capable of generating an aerosol by heating the electrically heated smoking article 50 according to the present invention will be described. The aerosol-generating device 100 described below includes an aerosol-forming substrate, such as a liquid composition or a tobacco sheath, inside the smoking article, such as the electrically heated smoking article 50 described in the present invention, and is wrapped in a conventional cigarette form as wrapping paper. The wrapped electrically heated smoking article 50 has a cavity into which the aerosol-forming substrate of the smoking article inserted into the cavity is heated by a heater provided in the aerosol-generating device to form an aerosol, which is grippable and portable. It is an aerosol-generating device of size. The heater may be provided by a resistance heating method or an induction heating method, as described below. For example, the heater is heated to a temperature of 100 to 400° C., and is provided inside the electrically heated smoking article 50 inserted into the cavity of the aerosol-generating device. The aerosol-forming substrate is heated to generate an aerosol. According to a preferred example, the target temperature may be in the range of 200 to 350 °C, and according to a more preferred example, the target temperature may be in the range of 250 to 320 °C (eg, 280 °C as the target). May be). In some cases, the target temperature may be in the range of 150 to 250°C (for example, 180°C may be set as the target temperature). This is whether the object to generate an aerosol is a liquid composition (such as glycerin) or a cigarette. Or it may vary depending on whether the liquid composition such as glycerin is a moistened tobacco body. In any case, since the aerosol generated in the electrically heated smoking article 50 is sucked into the user's mouth through the tube 54 and the filter 52, the temperature of the generated aerosol is excessive even when considering cooling during the inhalation process If it is high, the target temperature of the heating element should be determined in advance in consideration of this point because it may cause discomfort to the user or burns, and excessive aerosol may occur, which may cause multiple puffs. In addition, the upper limit of the target temperature of the heating element is limited as described above.

According to a preferred embodiment, the temperature at which the generated aerosol passes through the tube 54 and the filter 52 may be measured as the mouth end temperature. In order to not cause discomfort to the user, the temperature of the aerosol is 50°C. It should be less than, preferably, at a temperature of 45° C. or less. The preferred aerosol mouth end temperature has a temperature range of 25 to 45 °C, and the more preferred aerosol mouth end temperature has a temperature range of 30 to 40 °C.

The aerosol-generating device 100 includes a rechargeable battery 110 that is provided in the device and functions as a DC power source, and a control unit 120 that controls the output from the battery 110. The conceptual diagram of the aerosol-generating device 100 is shown in FIG. 5 together with the electrically heated smoking article 50, and is schematically illustrated in cross-section for the purpose of explaining the heating method for each embodiment. For convenience of explanation, the electrically heated smoking article 50, which is a smoking article, is basically arranged in the order of a filter 52-a tube 54-a gel-like aerosol-generating cartridge 56-a cigarette body 58, and wrapping paper It will be described based on the configuration wrapped in (60). It has been already described that the relative positions of the gel-like aerosol-generating substrate 56 and the cigarette body 58 in each case may be interchanged.

In addition, the following descriptions are provided for illustrative purposes only and are not limited to the scope of the present invention. Those of ordinary skill in the art to which the present invention pertains may be able to construct an aerosol-generating system that falls within the scope of the present invention by partially deleting, adding some, or combining with other devices from the configuration of the aerosol-generating device illustrated below. You will find it easy.

5 is a view schematically showing a cross-section of an aerosol-generating device 100 according to a first embodiment of the present invention, with a conceptual diagram of an example aerosol-generating system to which the present invention can be applied, as described above.

The aerosol-generating system includes an aerosol-generating device 100 and an electrically heated smoking article 50. Here, the electrically heated smoking article 50, which is a smoking article, has a filter 52, a paper tube 54, a gel-like aerosol-generating cartridge 56, and a cigarette body 58 wrapped by the wrapping paper 60 as described above. And is inserted into the hollow provided in the aerosol-generating device 100.

The aerosol-generating device 100 heats the liquid composition absorbed in the gel-like aerosol-generating cartridge 56 to heat the pipe heater 130b by electrical resistance to generate an aerosol, and the tobacco kerosene of the cigarette body 58. It includes an invasive heater (130a) by electrical resistance to generate an aerosol. In addition, it includes a battery 110 for supplying power to these

heaters

130a, 130b, and a control unit 120 configured to control power supply from the battery 110 to the

heaters

130a, 130b.

The intrusive heater 130a according to the first embodiment described above may be a blade shape in which a heater pattern is printed on the outside, or may be a rod-shaped shape. In any case, a temperature sensor pattern is also provided along with a heater pattern so that the temperature at the surface of the intrusive heater 130a is sensed and power supply to the intrusive heater 130a can be controlled according to the sensed value. As in the first embodiment, when the intrusive heater is inserted into the cigarette body 58 to heat the cigarette body 58 to form an aerosol inside the cigarette body 58, it is in contact with the cigarette body 58 and is heated immediately. It can help generate aerosols. Since the gel-like aerosol-generating substrate cartridge 56 is formed by crumpling or rolling materials physically connected to each other as described above, when the intrusion heater 130a is not properly inserted or inserted, the gel receptor may not be properly separated when removed again. Since there is, the intrusion heater 130a is preferably inserted only up to the cigarette body 58.

The pipe heater 130b according to the first embodiment described above is also a pipe in which a heater wire or a planar heating element pattern is printed or provided on the outside. The pipe heater 130b is provided with a temperature sensor pattern as in the intrusion heater 130a, so that the temperature is sensed and the power supply to the pipe heater 130b can be controlled according to the sensed value. The pipe heater 130b heats the gel aerosol-generating substrate cartridge 56 from the side surface of the gel-type aerosol-generating cartridge 56 of the electrically heated smoking article 50, so that the aerosol-generating substrate present in the gel form in the gel-like aerosol-generating cartridge It is heated to generate an aerosol.

The aerosol may be generated by heating the aerosol-generating substrate to a temperature range of 150-350 °C by the above heater, and the aerosol generated by the user's inhalation passes through the paper tube 54 and the filter 52 through the user's mouth. Is inhaled. For example, the intrusive heater 130a may generate aerosols derived from tobacco cuts by heating the tobacco cuts of the tobacco body 58 to a temperature range of 150-250°C, and the pipe heaters 130b may generate a gel-like aerosol. The gel receptor of the cartridge 56 can be heated to a temperature range of 250-350°C to generate an aerosol derived from the liquid composition of the gel receptor. The above temperature conditions may be opposite to each other. Even if heated to the above temperature range, the wrapping paper is not burned and a part of the wrapping paper may be leaked.

Of course, the heater pattern of each

heater

130a, 130b, the sensing unit and the control unit are electrically connected, respectively, and the battery and the control unit are also electrically connected.

6 is a view schematically showing a cross-section of an aerosol-generating system according to a second embodiment of the present invention.

The configuration of the electrically heated smoking article 50 is the same as in the case of the first embodiment.

The aerosol-generating device 100 according to the second embodiment is a case in which a gel-type aerosol-generating cartridge 56 and a pipe heater 132 of one resistance heating method corresponding to the cigarette body 58 are provided. Like the pipe heater 130b according to the first embodiment described above, a heater wire or a planar heating element pattern is a pipe printed or provided on the outside. A temperature sensor pattern is also provided to the pipe heater 132 according to the second embodiment to allow temperature to be sensed and to control power supply to the pipe heater 132 according to the sensed value.
