Description

[Technical field]

[0001] The present invention uses a dedicated heating device to generate aerosols including an aerosol former (but The aerosol (gas) produced by heating the outer surface of a tobacco plant (not including tobacco plants) The present invention relates to a smoking cartridge for smoking a cigarette, and more specifically, to a smoking cartridge for smoking a cigarette, the heat from the outer periphery of the paper tube is absorbed in the paper tube. A smoking cartridge configured to smoothly transmit the aerosol to the packing that constitutes the aerosol generating member. This document relates to the technology that provides these products. [Background technology]

[0002] In recent years, with the health consciousness and the health hazards of nicotine, the use of tobacco as an alternative to conventional cigarettes has become more common. Non-tobacco plants that do not contain tobacco leaves and aerosols that provide the enjoyment of smoking The aerosol generating components such as the former 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 a heating device, and is used by inserting it into the heated smoking device. Smoking devices that generate aerosol by heating are called "smoking cartridges." Smoking cartridges are essential consumables for heated smoking devices. Unlike cigarettes, which are burned and smoked, the aerosols produced by heating are inhaled. Although the term "smoking" refers to inhaling tobacco, it is used in this specification.

[0003] As mentioned above, heated tobacco products are smoking devices that are 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 traditional cigarettes, it is a product that meets the health consciousness and is also a product that has never been seen before. A variety of smoking cartridge products with rich tastes have been developed (see Patent Document 1, etc.). Many of these are commercially available and are becoming more widely used.

[0004] Here, there has been no heating device for heating the aerosol generating member in the past. Since it is a new product, various heated smoking products with excellent design and functionality have been developed. These methods have a large impact on the generation of aerosols. There are two main types of heating systems, and both types of heating devices are available on the market. That is, the aerosol filling the inside of 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 applying a heating blade to the filling material inside the aerosol generating component One method is to insert a heater or the like 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 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. The end of the cigarette that is closest to the mouth is generally fitted with a filter.

[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, since heated smoking devices are new products, they are expected to have high design quality. 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. This is sufficient, so the heating method is the two types mentioned above, and the insertion port for the smoking cartridge The size of the inner aperture 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 various smoking tastes are available, The thickness of the edges is almost the same.

[0008] Smoking cartridges, like cigarettes, burn aerosol-generating fillers. It does not cause smoking, and does not require a large amount of filling material to generate the smoking aerosol. The proposal is not intended to be used for a heated smoking device with a high level of design. The number of heated tobacco smoking cartridge products available is comparatively low compared to conventional cigarettes. The thickness is relatively thin. And the smoking cartridge, which is a consumable item for heated tobacco, is an air 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 these into the two types of heated smoking devices mentioned above.

[0009] The smoking cartridge products currently offered are the insertion parts of heated smoking devices. Products with significantly different lengths are available to suit different shapes. Examples of products that can be applied to the heating method (hereinafter also referred to as peripheral heating) include There are two types: a long one with a length of 75mm and a short one with a total length of 55mm. A method in which a heating blade or the like is inserted into the packed material of the sol generating material to heat it (hereinafter referred to as the heating blade method) The product for application to the 3-phase type is about 50 mm in length and is suitable for peripheral heating. 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 filled 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 heating blade method 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 by the smoking cartridge when inserted into the device depends on the heating method of the heated smoking device. The difference is that the cartridges for the peripheral heating method are different from those for the heating blade method. It occupies a larger area in the length direction than the smoking cartridges used in There is a difference.

[0010] In addition, according to the inventor's research, a smoking cartridge for use in the peripheral heating method The product is a smoking cartridge product for use with the heating blade method, with its exterior substrate being The thickness of the outer packaging material, such as paper, is smaller than that of the outer packaging material. In this case, 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 are different. Unlike conventional heating, it is necessary to heat a wide area and to heat the inside of the filling through the exterior substrate. However, it is difficult to heat the inside of the filling by heating it 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 use in heated smoking devices, the filling material is fitted with a heating blade, etc. Since the material is heated while inserted, the exterior base material used must be strong enough not to break even if the filling expands. The strength required for the material is such that it needs to be thick to a certain extent. For example, thin paper Thick paper about 0.1 mm thick is used, which is made by laminating layers to increase its strength. Thus, in the development of smoking cartridges, the following points were considered when applying them to heated smoking devices: It is necessary to take into consideration the effects 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 material, 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 and other materials used as thin as possible, but this makes the cartridge The strength of the cigarette itself decreases. Conventional cigarette exterior materials include 0. However, the paper is suitable for peripheral heating type heated smoking devices. In the case of smoking cartridge products for use in smoking, the thickness of the exterior substrate increases with the increase in aerosol generation. The range of usable paper thicknesses is limited because of the low thermal conductivity of the raw material. It cannot be made too thick. Specifically, the exterior substrate is preferably 0.01 mm to 0.05 mm thick. In the case of paper tubes made of thinner paper, usually less than 0.03 mm, good thermal conductivity is obtained. However, the strength is weak, and especially after smoking, the heated part turns brown due to heat and in some cases According to the inventor's research, the outer packaging paper tube is 0.1 mm thick. If the paper is thicker than this, it will be stronger and there will be no risk of the paper tube breaking after heating. This can be suppressed, but the thermal conductivity is poor, and sufficient heat does not reach the center. It is possible to increase the heating temperature, but this will result in more burning and a worsening of the flavor. This creates a problem of adverse effects on the

[0012] In addition, the inventors have been investigating the smoking car used in the peripheral heating type heated smoking device. Unlike smoking cartridges that use a heated blade, The length of the aerosol generating component filled with the filling material for generating aerosols is 20 m. Since the length is 35 mm, the heating area is wide, and the exterior substrate is thin. However, it is not easy to heat the filling material uniformly and satisfactorily 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 filling material is inserted into the container and heated, the heated filling material is divided into two parts: the outer part that is in contact with the exterior substrate 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. For this reason, in smoking cartridges that use a 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 it with the peripheral heating method. The exterior base material has turned brown, and there are also some severely burnt areas in the filling material inside the exterior base material. This is because, in normal smoking, the aerosol contains a burnt odor. In such cases, the smoking taste may be affected by the burnt parts. Furthermore, the heating area was heated uniformly, and the smoking cartridge after heating was When the condition of the packing was observed, it was found that the packing near the end opposite the filter was heated. It was also found that the filling was insufficient and that the entire filling was not heated properly. I put it out.

[0014] Therefore, an object of the present invention is to provide an aerosol powder that is contained in a paper tube that is an exterior substrate. The aerosol generating member, which is made of a filling material including aerosols, is filled by heating the outer periphery of the paper tube. In a smoking cartridge that inhales the aerosol (gas) generated from the filling, The heat from the aerosol-generating member is absorbed through the paper tube, which is the outer base material, and reaches not only the outer periphery of the aerosol-generating member but also the center The air is heated smoothly and uniformly for up to 10 minutes to produce an aerosol. The smoking case 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 will reduce the occurrence of burning in the filling material inside the outer substrate, 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 situations. [Means for solving the problem]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, preferred embodiments of the smoking cartridge of the present invention will 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 side which is the mouth side when smoking. The other end of the device 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 in the filter section. The aerosol generating member and the aerosol generating member are housed inside a cylindrical exterior 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 base material has 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 exterior base material is a paper tube wound with paper having a thickness of 0.1 mm to 0.6 mm, At least the portion of the paper tube in which the aerosol-generating member is stored is provided with a pierced hole. The film is characterized by having one or more holes. These through holes (hereinafter referred to as through holes) As shown in FIG. 1 and FIG. 2, the outer packaging substrate 5a is a paper tube. The ... As described above, it is preferable that a plurality of the filling members are provided. The smoking cartridge is inserted into a heated smoking device that heats the outer periphery of the product. The material is made of thin paper with a thickness of about 0.01mm to 0.05mm. The first cartridge 10 has an exterior base material 5 or 5a having 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. 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] As configured as above, the first cartridge of the present invention provides the following effects: As described above, the paper cylinder constituting the exterior base material of the cartridge of the present invention is thick. Since it is made of paper, it is different from the thin paper that constitutes conventional smoking cartridges. The heat transfer to the packing, which is the aerosol generating material, is inferior to that of the paper tube. In this case, the heat transfer through the paper tube to the center of the packing is poorer. In contrast, in the first cartridge 10 of the present invention, the outer periphery of the heated paper tube has one or more through holes 1. In addition, since a plurality of holes are preferably provided, a difference in heat conduction occurs 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 heat conduction to the outer periphery are uniform. 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 exterior substrate 5 or 5 In the case where a through hole 1 is provided in the part of the paper tube where the filling material is stored, the through hole 1 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 wall and the heating state of the center part of the packing 3 are the same. Therefore, it is preferable to provide a plurality of through holes. By providing the through holes, more uniform heating is possible. At least one is provided in the part of the cylinder where the filling material, which is the aerosol generating member, is stored. The positions of the other through holes are not particularly limited. When the product was heated and the heating condition was tested, For example, the through holes shown in FIG. 1B and FIG. 2 were insufficiently heated. As such, at least in the above cases where it was confirmed that heating was insufficient in conventional products, For example, at a position 3 mm to 10 mm from the end. 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 is, for example, aligned with each other. The electrodes may be provided in a uniform manner or in a scattered manner. For example, as shown in FIG. 1B, the part of the paper tube where the filling is stored has multiple The through holes may be arranged so that their horizontal positions are the same. In that case, as shown in FIG. 1B 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 a preferred embodiment to provide the ion exchange film 100 in a position facing the ion exchange film 100. 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 of (b), there are four combinations (eight through holes) of which the through holes are arranged. In the example of (c), there are two combinations (four through holes). 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. For example, Approximately 0.2mm to 0.5mm is preferable.

[0028] When multiple 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 into the grooves, the through holes are arranged in a spiral shape relative to each other in the longitudinal direction. As described above, the embodiment in which 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), In addition to the part of the paper tube (a) in which the filling 3 is stored, the through hole 1 is also filled with smoke when smoking. The hollow space through which the generated aerosol flows and the temperature at which the generated aerosol is heated are suitable for smoking. It is also preferable to provide the cooling member 2, which is designed to be cooled, in the portion housing the cooling member 2. This is a good form.

[0030] In the manner described above, at least the packing 3, which is the aerosol generating member, is stored 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 hole 1 provided in the paper tube. The heat is now transferred to the inside of the filling 3, and the outer and central parts of the filling that are in contact with the paper tube are heated. The heating condition can be made uniform and homogenous. Thickness is 0.1mm to 0.6mm The present invention is a paper tube having a diameter of 1.0 mm or less and an exterior substrate 5 or 5a having one or more through holes. For the first cartridge, a smoking cartridge using a paper tube of the above thickness without a through hole is used. In the case of a cartridge (not shown), as described above, the outer portion of the filling 3 that contacts the paper tube and A temperature difference occurs between the contact area and the center area, causing uneven heating of the filling 3. In particular, when the thick paper tube is used as the outer packaging, When using this material, the thermal conductivity is poor, and the center of the filling may not be heated. If the heating temperature is increased, the outer packaging paper tube and some of the contents inside may burn. This can cause the product to become loose.

[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 hole 1, heat is transferred to the inside of the filling 3 more quickly through the through hole 1. This allows the exterior base material 5 or 5a forming the paper tube to be thicker. This can improve the strength of the smoking cartridge. The exterior base material 5 or 5a constituting the above is a paper tube having a thickness of 0.1 mm or more and 0.6 mm or less, The first smoking car of the present invention is characterized by having a thicker paper than conventional products. The cartridge 10 can be designed to have a smooth flow of the through holes 1 into 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 such a manner. There is no particular limitation on the method of forming the through holes in the paper tube constituting the present invention. The paper material with the through holes at the desired positions is wound in a single layer or spirally to form a paper tube. In the final step of the method or manufacturing the first cartridge 10, a desired mark is applied to the paper tube by a laser or the like. A method of providing holes of a desired size at a desired position can be given.

[0032] The exterior substrate 5 or 5a characterizing the first cartridge 10 of the present invention is, as described above, At least the aerosol-generating member is housed in the paper tube which is the exterior substrate 5 or 5a. The material of the paper tube does not need to be special, as long as there is at least one through hole 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 respect, the second aspect of the present invention described below can be easily used. The same is true for the cartridge.

[0033] The first cartridge 10 of the present invention is constituted by a member other than the above-mentioned 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, which is provided as necessary, are described in the prior art cited above. These points are described in detail in the "Second Card of the Invention" below. The same is true for the "Tridge" case.

[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 pulp generating member (filler) 3 is heated by peripheral heating, and a constant amount of the pulp 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. The taste is determined by the smoke concentration in the airflow. I confirmed 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 made of non-tobacco leaves and aerosol formers such as glycerin. The filling material used was a paper tube containing cellulose. The thickness of the paper tube in which the filling material was contained was 0.6 mm. In the first cartridge used in the test, the 5 At the position of 1.5 mm, eight through holes with a diameter of 0.5 mm were formed at equal intervals using a laser (Figure 1 2(c)).

[0036] For comparison, a first cartridge having the above-mentioned configuration used in the test was provided with no through-hole. A smoking cartridge for comparison was prepared with the same shape as above, except that the The time course of the taste elements was examined. 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 the Cartridge 10, the smoke concentration increases early on in the inhalation process, and smoke continues to accumulate for a long period of time. In contrast, a comparison test using a smoking cartridge showed that As shown in Figure 5B, there was no increase in smoke concentration in the early stages of inhalation. It was confirmed that aerosol generation by heating did not occur immediately after the test. The state of discoloration of the packing and the paper tube of the aerosol-generating component after the aerosol-generating component was observed. As a result, in the first cartridge 10 of the present invention, which has a through hole in the paper tube, It was confirmed that the heat was uniform, including the surrounding area. In the comparative smoking cartridge, which does not have the nicotine, the heating near the tip is insufficient. In addition, compared to the first cartridge 10 of the present invention, there were more burnt parts and a stronger burnt smell. 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 winding paper having a thickness of .1 mm to 0.6 mm, and at least A paper tube is formed in a portion of the paper tube in which a filling material, which is an aerosol generating member, is stored. The sheet is characterized by having one or more thin regions that are thinner than the thickness of the paper it is made of.

[0038] The thickness of the paper is thinner than that of the paper tube constituting the second cartridge of the present invention. 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 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 total area of ​​the thin region provided in the portion in which the filler, which is the sol generating material, is The area of ​​the paper tube in which the contents are stored must be no less than 10% and no more than 50% of the total area of ​​the paper tube. 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 insulating layer 11 may be provided in a scattered state at a plurality of positions. As shown in FIG. 1, the thin region may be provided in a continuous band shape. The methods are as follows. For example, as shown in FIG. 3(a), A strip-shaped (tape-shaped) paper 5a (outer packaging 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 material (material) around the paper tube. 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-like paper so that the ends in the longitudinal direction overlap, the overlapping parts are thicker. In this case, a thin portion is formed on the paper cylinder, and then a continuous thin region 7 is formed on the paper cylinder.

[0040] The thin area constituting the second cartridge 20 of the present invention is as shown in FIG. In addition, in the same manner as in conventional paper cigarettes, when forming a paper cylinder by wrapping the exterior base material 5a in a single layer, By using a rectangular piece of paper on which the hand area 7 is provided in a scattered manner, the thin area is scattered As shown in FIG. 4(b), the outer base material 5a can be 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 100 mm or less, a paper tube having a plurality of continuous thin regions 8 in the longitudinal direction can be obtained. Although not shown in the figure, it is possible to apply another paper to a part of the thin paper continuously or in a continuous manner. The thin regions are also present in a scattered state by laminating the thin regions in a scattered state. Alternatively, a paper tube having a structure in which thin regions exist continuously can be obtained. [Explanation of symbols]
