Description

[Technical Field]

[0001] The present invention uses a dedicated heating device to generate aerosols containing an aerosol former (but The aerosol (gas) produced by heating the outer surface of the tobacco plant (which does not contain tobacco plants) The smoking cartridge is a type that is inhaled by a cigarette, and the heat from the outer surface of the paper tube is absorbed by the inside of the paper tube. A smoking cartridge configured to smoothly transmit the aerosol to the packing that constitutes the aerosol generating member. It relates to the technology that provides the product. [Background technology]

[0002] In recent years, with the health consciousness and in consideration of the health hazards of nicotine, there are now many people who are looking to replace traditional cigarettes with tobacco. Non-tobacco plants and aerosols that do not contain tobacco leaves are used to provide the pleasure of smoking. Aerosol generating components such as formers are heated with a dedicated heating device, and the generated aerosol (gas) The development and use of heated tobacco products, which are smoked by smoking a cigarette, is progressing. The device is called a heated smoking device or heating device, and is inserted into the heated smoking device. Smoking devices that generate aerosols by heating are called "smoking cartridges." Smoking cartridges are essential consumables for heated smoking devices. Unlike cigarettes, which are burned and smoked, the aerosol generated by heating is inhaled. Although smoking involves inhaling tobacco, it is referred to as "smoking" in this specification.

[0003] As mentioned above, heated tobacco is a smoking device that is completely different from conventional cigarettes. Recently, by using various materials that do not contain tobacco leaves as aerosol generating materials, Beyond its role as a substitute for conventional cigarettes, it is a product that meets health-conscious needs and offers a unique Various smoking cartridge products with rich tastes have been developed (see Patent Document 1, etc.), and many Many of these are now commercially available and in use.

[0004] Here, there has been no heating device for heating the aerosol generating member in the past. As this is a new product, various heated smoking devices with excellent design and functionality have been developed. These methods have a significant impact on the generation of aerosols. There are two main types of heating systems, and both types of heating appliances are commercially available. That is, the aerosol filling inside the aerosol generating member is injected from the outer periphery of the aerosol generating member through the outer substrate. The method of heating the filling material that generates the aerosol and the method of heating the filling material inside the aerosol generating element One method involves inserting a heater or similar device to directly heat the filler contained within the exterior base material. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6371928 Summary of the Invention [Problem to be solved by the invention]

[0006] In the case of any of the above types of heating appliances, the insert provided in the heated smoking device Inserting a smoking cartridge through the inlet and heating the aerosol-generating member inside the heating device; Hold the heated smoking device in your hand and release the aerosol from the outer end of the device while heating it. A filter is generally provided on the end of the cigarette that is closest to the mouth.

[0007] The outer shape of the smoking cartridge depends on the shape of the insertion part provided in the heated smoking device. As mentioned above, heated smoking devices are new products, so they are designed to be highly sophisticated. Various types of products are known, and product differentiation is being sought. The function is to heat the aerosol generating material inserted inside the smoking device and generate aerosol. The heating method is the two types mentioned above, and the insertion port of the smoking cartridge is The size of the inner diameter is not different for each product, but is almost standardized. Since there is an unlimited number of raw materials that can be used as aerosol generating materials, Although various smoking cartridge products that provide different smoking tastes are available, The thickness of the edges is almost the same.

[0008] Smoking cartridges, like cigarettes, burn a filler that is an aerosol-generating material. It does not cause a smoking problem, and does not require a large amount of filling material to generate a smoking aerosol. Since the proposed product is not intended to be used for heating smoking devices and is intended to be used for highly designed heated smoking devices, The heated tobacco smoking cartridge products available on the market are relatively The thickness is relatively thin. And the smoking cartridge, which is a consumable item for heated tobacco, is Any device capable of smoking an aerosol generated by heating an aerosol generating member may be used. As mentioned above, the thickness of the product is almost the same, so it can be used with any of the various smoking cartridge products. It is also possible to insert this into the two types of heated smoking devices mentioned above.

[0009] Here, the smoking cartridge products currently offered are the insert part of the heated smoking device. Products with significantly different lengths are available to accommodate different shapes. As a product for application to the heating method (hereinafter also referred to as peripheral heating), for example, There are two types: a long type with a length of 75mm and a short type with a total length of 55mm. A method of heating by inserting a heating blade or the like into the filler of the sol-generating material (hereinafter referred to as the heating blade method) The product for application to the circumferential heating is about 50 mm in total length. According to the inventor's investigation, the total length applied to the peripheral heating is 75 In the long type smoking cartridge, the filling material for generating aerosol is The length of the heated area is about 35 mm, and the total length is 55 mm. The length of the heating area of ​​the heater is about 20 mm. A smoking cartridge with a total length of about 50 mm is filled with the filling material to generate the aerosol. The length of the filled part (heated area) is short, about 12 mm. The heating area required for the smoking cartridge when inserted varies depending on the heating method of the heated smoking device. The difference is that the smoking cartridges that are used for the peripheral heating method are different from the heated blade method. It occupies a wider area in the length direction than the smoking cartridge that is applied to There is a difference.

[0010] Furthermore, according to the inventor's investigation, a smoking cartridge for use in the peripheral heating method has been developed. The product is a smoking cartridge product for use with a heating blade method, with its exterior substrate. The thickness of the outer substrate, such as paper, is thinner than that of the outer substrate. The exterior base material is made of paper with a thickness of about 0.01 mm to 0.05 mm. The reason is that in the case of peripheral heating type heated smoking devices, the heating blade type heated smoking devices Unlike conventional heating systems, it is necessary to heat a wide area and even the inside of the packing through the outer substrate. However, it is difficult to heat the inside of the filling by heating from the outside. This is thought to be due to the need to reduce the thickness of the paper used as the base material. In the case of smoking cartridges for heated smoking devices, the filling material is fitted with a heating blade, etc. Since the heat is applied while the contents are inserted, the outer substrate used must be strong enough to withstand the expansion of the contents. The strength required is to make the material thicker to a certain extent. Thick paper about 0.1 mm thick is used, which is made by laminating layers to increase its strength. In this way, in the development of smoking cartridges, when applied to heated smoking devices, It is necessary to consider the impact on smoking cartridges caused by differences in heating methods.

[0011] That is, in the case of a peripheral heating type heated smoking device, the aerosol generating member, the filling The contents are heated through the exterior substrate that constitutes the cartridge, so the exterior substrate is It is desirable to make the thickness of the paper or other material used as thin as possible, but this makes the cartridge The strength of the cigarette itself decreases. Conventional cigarette outer packaging materials include 0. However, the thickness of the paper is 0.2mm to 0.5mm. In the case of smoking cartridge products intended for use in smoking, the thickness of the outer substrate increases with the increase in aerosol generation. The range of usable paper thicknesses is limited because the thermal conductivity to the raw material is low. It cannot be too thick. Specifically, the outer substrate is preferably 0.01 mm to 0.05 mm. In the case of paper tubes made of thinner paper, usually 0.03 mm or less, good thermal conductivity is obtained. However, the strength is weak, and especially the heated part after smoking turns brown due to the heat, and in some cases According to the study by the inventor, the outer packaging base paper tube is 0.1 mm thick. If the paper is made of thicker paper than this, it will be strong and there will be no risk of the paper tube breaking after heating. However, this results in poor thermal conductivity and insufficient heat reaching the center. It is possible to increase the heating temperature, but this will result in significant burning and a worsening of the smoking taste. This creates a problem of adverse effects on the

[0012] In addition, during the course of the study, the inventor Unlike smoking cartridges that use a heated blade, The length of the aerosol-generating element filled with the filling material for generating aerosols is 20 m. Because the heating area is large, even if the outer substrate is thin, the heating area is large. However, it is not easy to heat the filling material uniformly and in a good condition from the outer peripheral surface through the outer substrate. Specifically, the smoking cartridge is a heated smoking device that uses a peripheral heating method. When the heated filling material is inserted into the outer shell and heated, the outer shell and the central part It is expected that a temperature difference will occur between the two locations due to heating, which will cause uneven aerosol generation. Therefore, in smoking cartridges that are heated by the peripheral heating method, A heated smoking device that is designed to heat the filling sufficiently to the center. It is thought that...

[0013] The inventor observed the smoking cartridge after heating using the peripheral heating method. The exterior base material has turned brown, and there are also some heavily burnt areas in the filling material inside the exterior base material. This is because the smell of burnt tobacco mixed with the aerosol during normal smoking is In such cases, the smoking experience may be affected by the burnt parts. Furthermore, regarding the uniform heating in the heating area, the smoking cartridge after heating was When observing the state of the packing, it was found that the packing near the end opposite the filter was heated. It was also found that the filling was insufficient and not heated properly throughout. I put it out.

[0014] Therefore, an object of the present invention is to provide an aerosol powder stored in a paper tube that is an exterior substrate. The aerosol generating element, which is made of a filling material containing aerosols, is heated from the outer surface of the paper tube. In a smoking cartridge of the type in which the aerosol (gas) generated from the filling is inhaled, The heat from the aerosol-generating element is transferred through the paper tube, which is the outer base material, to the center as well as the outer shell of the aerosol-generating element. The temperature is then smoothly transferred to a suitable state for generating aerosols within minutes, and the heat is distributed as uniformly as possible. This smoking can has been improved so that the strength of the paper tube after heating is not a major problem. Another object of the present invention is to provide a cartridge product heated by a peripheral heating method. This can reduce the occurrence of burnt contents in the outer packaging, and is expected to improve the smoking experience. The present invention aims to provide a smoking cartridge product that can be used in a variety of ways. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0022] A preferred embodiment of the smoking cartridge of the present invention will now be described with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0023] The smoking cartridge of the present invention is heated by heating the filling material, which is an aerosol-generating member, from the outer periphery. It is intended to be inserted into a heated smoking device that uses a method of heating an object (peripheral heating). The filter member is disposed on one end of the cigarette that is the mouth side when smoking. The other end of the nozzle is equipped with an aerosol former that generates aerosol by heating using a peripheral heating method. an aerosol-generating member (but not including a tobacco plant) is disposed, and the filter section The aerosol-generating member and the aerosol-generating member are housed inside a cylindrical outer substrate and integrated together. The smoking cartridge of the present invention has the above-mentioned basic configuration. In addition, the first invention and the second invention are characterized in that the cylindrical exterior substrates each have the following configuration: This includes the second invention.

[0024] [First invention] The first smoking cartridge of the present invention (hereinafter also referred to as the first cartridge of the present invention) is The outer packaging substrate is a paper tube made by wrapping paper having a thickness of 0.1 mm to 0.6 mm, At least the paper tube has a perforated hole in the packing portion where the aerosol-generating member is housed. The film is characterized by having one or more holes. These through holes (hereinafter referred to as through holes) As shown in FIGS. 1 and 2, the outer packaging substrate 5a is a paper tube, and the outer packaging substrate 5a is a paper tube. As mentioned above, it is preferable that a plurality of the filling The smoking cartridge is inserted into a heated smoking device that heats the outer periphery of the object. The material is made of thin paper with a thickness of about 0.01mm to 0.05mm. The first cartridge 10 has an exterior substrate 5 or 5a with a thickness of 0.1 mm or more and 0.6 mm or less. One of the features of this product is that it is made of thick paper underneath. The same applies to the second smoking cartridge (hereinafter also referred to as the second cartridge of the present invention). Hereinafter, the first cartridge and the second cartridge will be collectively referred to as the cartridge of the present invention. Also called.

[0025] With the above-described configuration, the first cartridge of the present invention provides the following effects: As described above, the paper tube constituting the exterior base material of the cartridge of the present invention is thick. It is made of paper, so it is different from the thin paper that makes up conventional smoking cartridges. Compared to a paper tube, the heat conduction to the packing, which is the aerosol generating member, is inferior. In this case, the heat transfer to the center of the packing through the paper tube will be poorer. In contrast, in the first cartridge 10 of the present invention, one or more through holes 1 are formed in a paper tube whose outer periphery is heated. In addition, preferably a plurality of holes are provided, so that there is no difference in heat conduction between the hole portion and the non-hole portion. The aerosol-generating member 3 of the smoking cartridge 10 is filled through a paper tube. When heating the heater, the heat conduction to the center and the outer periphery is uniform, resulting in Therefore, the unevenness in the generation of aerosols is reduced, and the generated aerosols can be stabilized. It becomes possible.

[0026] More specifically, as defined in the first cartridge 10 of the present invention, the outer substrate 5 or 5 When a through hole 1 is provided in the part of the paper tube where the filling material is accommodated, The heat that passes through the paper tube is quickly transferred to the inside of the filling 3. The heating state of the outer part of the packing 3 in contact with the surface of the packing 3 is the same as the heating state of the center part of the packing 3. Therefore, it is preferable to provide a plurality of through holes. By providing the holes, more uniform and even heating is possible. At least one is provided in the part of the cylinder where the filler, which is the aerosol generating member, is stored. The positions of the other through holes are not particularly limited. When the product is heated and the heating condition is tested, the filling near the end opposite the filter Because the heating was insufficient, for example, the through-holes were As such, at least in the above cases where it was confirmed that conventional products were not heated sufficiently, For example, it is preferable to provide one or more in the vicinity of the end portion. It is preferable to provide one or more through holes in the insulating layer.

[0027] In addition, when a plurality of through holes are provided in the paper tube, the arrangement of the through holes may be, for example, in a mutually aligned manner. The electrodes may be provided in a uniform or scattered state. For example, as shown in Figure 1B, there are several The through holes may be arranged so that their horizontal positions are the same. In that case, As shown in (a) and (b), two through holes are arranged opposite each other with the center point of the paper tube in between. It is also preferable to provide the device in a position facing the sensor. There are two through holes at the same horizontal position on the paper tube, facing each other across the center point of the paper tube. In the example (b), there are four sets (eight through-holes) of combinations in which In the example shown in FIG. 1B(c), three through holes are provided at the same horizontal position on the paper tube. The size of each through hole is not particularly limited. A thickness of around 0.2mm to 0.5mm is preferable.

[0028] When a plurality of through holes are provided, they are arranged at the same horizontal position on the paper tube as exemplified above. As shown in FIG. 1A and FIG. 4(c), a plurality of through holes may be formed in a paper tube. When the through holes are inserted, they are arranged in a spiral shape in the longitudinal direction. As mentioned above, the case where a plurality of through holes are provided at the same horizontal position is also preferable. In this case, depending on the number and size of the holes, the first cartridge may break at that horizontal position. Therefore, when multiple through holes are provided in a paper tube, they should be placed at the same horizontal position. It is preferable to design the substrate so that there are not many through holes in the substrate.

[0029] When a plurality of through holes are provided, as shown in FIG. 1A or FIG. 4(c), the outer substrate 5 or 5 In addition to the part of the paper tube a where the filling 3 is stored, the through hole 1 is The hollow area where the generated aerosol flows and the temperature of the generated aerosol are suitable for smoking. It is also preferable to provide the cooling member 2, which is designed to be cooled, in the area where the cooling member 2 is accommodated. It is a good form.

[0030] As described above, at least the filler 3, which is the aerosol generating member, is contained in the paper tube. By providing one or more through holes in the portion where the first card of the present invention is inserted, According to the cartridge 10, the heat generated by the outer peripheral heating is quickly transferred through the through holes 1 provided in the paper tube. The heat is transferred to the inside of the filling 3, and the outer part of the filling that comes into contact with the paper tube and the center part The heating condition can be made uniform and even. Thickness is 0.1mm to 0.6mm The present invention is characterized in that the outer substrate 5 or 5a is a paper tube having a diameter of 100 mm or less and has one or more through holes. A smoking cartridge using a paper tube of the above thickness without a through hole is provided for the first cartridge. In the case of a cartridge (not shown), as described above, the outer portion of the filler 3 that contacts the paper tube, A temperature difference occurs between the contact area and the central area, causing uneven heating and Furthermore, partial burning may occur. When using a filling material, the heat conductivity is poor and the center of the filling may not be heated. If the heating temperature is too high for this problem, the outer packaging paper tube and part of the contents inside may be burned. This can cause problems such as fading.

[0031] As described above, the first cartridge 10 of the present invention is a paper tube that is an exterior base material 5 or 5a. By providing the through holes 1, the heat is transferred to the inside of the filling 3 more quickly through the through holes 1. This allows the thickness of the exterior base material 5 or 5a forming the paper tube to be increased. This can improve the strength of the smoking cartridge. The outer packaging substrate 5 or 5a is a paper tube having a thickness of 0.1 mm or more and 0.6 mm or less, The paper thickness is thicker than that of conventional products. The cartridge 10 can be designed to smoothly feed the filling material 3 by appropriately designing the number and arrangement of the through holes 1. Good heat transfer can be achieved, which gives the aerosol generation the desired characteristics. This shows that it is possible to design the first cartridge 10 of the present invention in this way. There is no particular limitation on the method of forming the through holes in the paper tube constituting the present invention. A paper material with holes at desired positions is wound into a paper tube either in a single layer or in a spiral. In the final step of manufacturing the first cartridge 10, a desired mark is applied to the paper tube by a laser or the like. For example, holes of a desired size are provided at desired positions.

[0032] As described above, the exterior substrate 5 or 5a characterizing the first cartridge 10 of the present invention is At least the aerosol-generating member is housed in the paper tube that is the exterior substrate 5 or 5a. The material of the paper tube is not particularly limited as long as there is one or more through holes in the part of the filling that is being filled. For example, if it is a material that has been used as cigarette paper, there is no problem. In this regard, the second invention of the present invention will be described below. The same is true for the cartridge.

[0033] The first cartridge 10 of the present invention is made up of a member other than the exterior base material 5 or 5a. The aerosol generating member (filler) 3 containing the aerosol former and the filter at the mouth The member 4 and the cooling member 2 provided as needed are those described in the prior art etc. These points are not particularly limited and can be appropriately used. The same is true for "Tridge."

[0034] FIG. 5A shows a method for measuring aerosol particles using the first cartridge 10 of the present invention having the configuration shown in FIG. 2(c). The fuel generating member (filler) 3 is heated by peripheral heating, and a constant amount of fuel is intermittently sucked in using a tool. As shown in Figure 5A, the temperature and flow rate were constant. The suction force and negative pressure each show a pulse. I checked that it was alive.

[0035] The first cartridge used in the test had an outer diameter of 6 mm and a total length of 7 mm, as shown in Figure 2(c). 5 mm, the length of the filling of the aerosol-generating member 3 is 35 mm, and the length of the filter member 4 is 1 7 mm, and the hollow space between the aerosol generating element and the filter element is 23 mm. The aerosol generating material 3 was a non-tobacco leaf and aerosol forming material such as glycerin. The thickness of the paper tube in which the filling material is contained is 0.6 mm. In the first cartridge used in the test, the 5 Eight through-holes with a diameter of 0.5 mm were formed at equal intervals at the position of 0.5 mm using a laser (Fig. 2(c)).

[0036] For comparison, a first cartridge having the above-described configuration used in the test was provided with no through-holes. A smoking cartridge for comparison was prepared with the same shape as above, except that the Figure 5B shows the time course of the taste elements for the comparative smoking cartridge. 5A and 5B are graphs showing the results of examining the time transition. In the case of Cartridge 10, the smoke density increases early on when suction begins, and smoke continues for a long period of time. In contrast, a test using a control smoking cartridge showed an increase in the concentration of As shown in Figure 5B, there was no increase in smoke concentration in the early stages of inhalation. It was confirmed that aerosols were not generated immediately after the test. After the aerosol-generating component was inspected, the discoloration of the packing and paper tube was observed. As a result, in the first cartridge 10 of the present invention in which a through hole is provided in the paper tube, It was confirmed that the heat was uniform, including the surrounding area. In the comparative smoking cartridge without the nozzle, the heating near the tip was insufficient. In addition, compared to the first cartridge 10 of the present invention, there are more burnt parts and the burnt smell is stronger. Confirmed.

[0037] [Second Invention] The second smoking cartridge (second cartridge) of the present invention is a cartridge having an exterior substrate of 0 A paper tube made by wrapping paper with a thickness of 0.1 mm or more and 0.6 mm or less, and at least The paper tube is formed in a portion of the paper tube where the filler, which is the aerosol generating member, is stored. It is characterized by having one or more thin areas that are thinner than the thickness of the paper it is made of.

[0038] The thickness of the paper tube constituting the second cartridge of the present invention is thinner than that of the paper tube. The thickness of the hand area is, for example, about 1 / 2 to 1 / 6 of the thickness of the paper that forms the paper tube. It is preferable to design it so that the ratio is about 1 / 5. If the thickness of the paper tube is 0.1 mm, the thickness of the thin area should be about 0.02 to 0.05 mm. In addition, if the thickness of the paper tube is 0.6 mm, the thickness of the thin area is It is preferable to design the thickness of the paper tube to be about 0.1 to 0.3 mm. The thin area provided in the portion where the filler, which is the sol generating member, is stored has a total area of The area of ​​the paper tube containing the above-mentioned contents must be between 10% and 50% of the total area. preferable.

[0039] The thin area 7 or 8 constituting the second cartridge 20 of the present invention is shown in FIG. As shown in FIG. 3 and FIG. 4(b), the electrodes may be provided in a scattered state at a plurality of locations. As shown in the figure, the thin region may be provided in a continuous band shape. The following methods are available. For example, as shown in Figure 3(a), A strip-shaped (tape-shaped) paper 5a (exterior substrate) having a continuous thin area 7 in the center of the hand direction. A method of forming a continuous thin region 7 on a paper tube by spirally winding a paper tube made of a material. For example, as shown in FIG. 3(b), a strip of paper 5a (exterior substrate) is When forming a paper tube by spirally winding, a thin strip of paper 5a having a uniform thickness is used. By wrapping the tape-shaped paper so that the longitudinal ends overlap, the overlapping parts become thicker. In this case, a thin section is formed on the paper tube, and a continuous thin region 7 is formed on the paper tube.

[0040] The thin area constituting the second cartridge 20 of the present invention is as shown in FIG. In addition, when forming a paper tube by wrapping the exterior substrate 5a in a single layer, as in the case of conventional paper cigarettes, By using a rectangular piece of paper on which the hand area 7 is scattered in multiple places, the thin area is scattered As shown in FIG. 4(b), it is also possible to obtain a paper tube having the outer substrate 5a. When the paper is wound once to form a paper tube, thin regions 8 are formed in stripes in the longitudinal direction. By using paper having a thickness of 1000 MPa, a paper tube having a configuration in which a plurality of thin regions 8 are continuously formed in the longitudinal direction can be obtained. Although not shown, it is possible to place another paper on a part of the thin paper continuously or The thin regions are present in a scattered state even when the thin regions are stacked in a scattered state. Alternatively, a paper tube having a structure in which thin regions exist continuously can be obtained. [Explanation of symbols]
