Description

The present invention relates to a smoking cartridge of the type in which aerosol (gas) generated by heating an aerosol-generating member (but not including tobacco plant) including an aerosol former using a dedicated heating device on the outer peripheral surface thereof is sucked. More specifically, the present invention relates to a technique for providing a smoking cartridge product configured such that heat from the outer peripheral surface of a paper tube is smoothly transmitted to the filler that constitutes the aerosol generating member inside the paper tube.

Considering the health hazards caused by nicotine in recent years, we have developed a special aerosol-generating material, such as a non-tobacco plant that does not contain tobacco leaves, and an aerosol former, as an alternative to conventional cigarettes to provide the enjoyment of smoking. The development and use of heated cigarettes that are heated with a heating device and inhale the generated aerosol (gas) are progressing. In this specification, the dedicated heating device is referred to as a heating smoking device or a heating device, and a smoking device that generates aerosol by heating, which is used by being inserted into the heating device, is a smoking device. called a cartridge. Smoking cartridges are essential consumables for heated smoking articles. It should be noted that the smoking cartridge does not inhale smoke when it is burned like a cigarette, but inhales an aerosol produced by heating, which is referred to herein as "smoking".

As described above, heated tobacco is a completely different type of smoking device from conventional cigarettes. Beyond their role as a substitute for cigarettes, various smoking cartridge products have been developed that meet health-consciousness and have unprecedented palatability (see Patent Document 1, etc.), and many of them are commercially available. , is coming into use.

Here, since the heating device for heating the aerosol-generating member is also a new product that did not exist at all in the past, various heat-type smoking device products with excellent design and functionality have been developed and are commercially available. It has been developed and is becoming more popular. There are roughly two types of heating methods that greatly affect the generation of aerosol, and heating devices for both heating methods are commercially available. That is, one method heats the aerosol-generating filling that is filled inside the aerosol-generating member from the outer periphery of the aerosol-generating member via the exterior base material, and the other method heats the filling that generates the aerosol inside the aerosol-generating member, and inserts a heating blade or the like into the filling inside the aerosol-generating member to heat the exterior. There is a method of directly heating the filling contained in the base material.

Japanese Patent No. 6371928

In the case of any of the heating devices described above, the smoking cartridge is inserted through the insertion opening provided in the heating device, the aerosol generating member is heated inside the heating device, and the heating device is heated. and smoke the aerosol from the end located outside the heating device while heating. A filter is generally provided on this end side, which is the mouth side.

The outer shape of the smoking cartridge depends on the shape of the insert provided in the heated smoking article. As mentioned above, since the heating type smoking article is a new product, various types of products with high design properties are known, and the products are being differentiated. On the other hand, the function of a heating smoking article is sufficient if it can generate an aerosol by heating the aerosol generating member inserted inside the smoking article. The size of the insertion opening and the diameter of the inside does not differ for each product, and is almost standardized. For this reason, since there is an infinite number of raw materials that can be used as aerosol-generating members, various smoking cartridge products have been provided that provide a variety of smoking tastes, but the thickness of the smoking cartridges is almost the same. .

The smoking cartridge does not burn the filling, which is an aerosol-generating member, like a cigarette, nor does it require a large amount of filling to generate smoking aerosol. Because of their application in heated smoking devices with high volatility, the provided heated tobacco smoking cartridge products are relatively thin in thickness as compared to conventional cigarettes. The smoking cartridge, which is a consumable item for heated cigarettes, may be any cartridge that can smoke the aerosol generated by heating the aerosol generating member. Any of a wide variety of smoking cartridge products can be inserted into heated smoking articles of the two types described above.

Here, currently available smoking cartridge products are provided with products that differ greatly in length according to the difference in shape of the insertion portion of the heating type smoking article. As a product to be applied to the method of heating the filling from the outer circumference (hereinafter also referred to as outer circumference heating), there are, for example, a long type with an overall length of 75 mm and a short type with an overall length of 55 mm. The total length of the product to be applied to the method of heating by inserting a heating blade or the like into the filling of the aerosol generating member (hereinafter also referred to as the heating blade method) is about 50 mm. shorter than According to studies by the present inventors, in a long-type smoking cartridge with a total length of 75 mm, which is applied to the outer circumference heating, the length of the portion (heating region) filled with the filling for generating aerosol is 35 mm. A short type with a total length of 55 mm has a heating area of about 20 mm. On the other hand, in a smoking cartridge having a total length of about 50 mm for application to a heating blade system, the length of a portion (heating region) filled with a filling for generating an aerosol is as short as about 12 mm. That is, the heating area required by the smoking cartridge when it is inserted into a heating smoking article differs depending on the heating method of the heating smoking article. The difference is that it occupies a wider area in the longitudinal direction than that of a smoking cartridge that applies to

Further, according to the studies of the present inventors, in the smoking cartridge product for applying the outer circumference heating method, the covering material such as paper constituting the smoking cartridge product for applying the heating blade method is used as the exterior base material. Thin ones are used compared to the thickness of the base material. Specifically, the exterior base material is made of paper having a thickness of about 0.01 mm to 0.05 mm. The reason for this is that, unlike heating blade type heating smoking tools, in the case of peripheral heating type heating smoking tools, it is necessary to heat the inside of the filling over a wide area through the exterior base material. On the other hand, since it is difficult to heat the inside of the filling by heating from the outer periphery, it is considered that the thickness of the paper that is the exterior base material needs to be reduced. On the other hand, in the case of a smoking cartridge that is applied to a heating-type smoking device using a heating blade method, the filling is heated while a heating blade or the like is inserted. Since the required strength is required and the thickness must be increased to some extent, a thick paper with a thickness of about 0.1 mm is used, for example, by laminating thin papers to increase the strength. Thus, in the development of smoking cartridges, it is necessary to take into consideration the effects on smoking cartridges caused by differences in heating methods when applied to heating-type smoking tools.

That is, in the case of a heating type smoking article that uses an outer peripheral heating method, the filler, which is the aerosol generating member, is heated via the exterior base material that constitutes the cartridge. It is desirable to make the thickness of the material as thin as possible. Paper with a thickness of 0.02 mm to 0.5 mm is used as a material for the outer base material of conventional cigarettes and other cigarettes. However, in the case of a smoking cartridge product for use with a heating smoking device that uses a peripheral heating method, the thicker the outer base material, the lower the heat transfer to the aerosol generating member. The thickness range is limited and cannot be too thick. Specifically, when the exterior base material is a paper cylinder formed of paper having a thickness of 0.01 mm to 0.05 mm, preferably 0.03 mm or less, good thermal conductivity can be obtained, but strength It is weak, especially after smoking, the heated part turns brown with heat and sometimes breaks. According to the studies of the present inventors, when the paper cylinder of the outer base material is formed of thick paper having a thickness of 0.1 mm or more, the strength is excellent and the paper cylinder can be prevented from breaking after heating. It has poor conductivity and does not allow enough heat to reach the core. On the other hand, it is conceivable to raise the heating temperature.

In addition, in the course of the study, the present inventors found that, in the case of a smoking cartridge used in a heating smoking device of the peripheral heating method, unlike the case of the smoking cartridge used in the heating blade method, the aerosol is generated. Since the length of the aerosol generating member filled with the filler is as long as 20 mm to 35 mm, the heating area that requires heating is wide, and even if the outer base material is made thin, the filling can be transferred through the outer base material. It was recognized that it was not easy to heat uniformly and in a good condition from the outer peripheral surface. Specifically, when a smoking cartridge is inserted into a heating smoking device that heats the outer periphery and is heated, there is a difference in the temperature of the heated filling between the outer shell portion in contact with the exterior base material and the central portion due to heating. This is expected to cause unevenness in aerosol generation. For this reason, it is considered that the smoking cartridge heated by the outer circumference heating method is designed so that the central portion of the filling is sufficiently heated by the outer circumference heating type heating smoking implement.

When the present inventor observed the smoking cartridge after heating by the peripheral heating method, it was found that the outer base material was discolored to brown and that the filling in the outer base material was also strongly burnt. Found it. From this, it was recognized that there is a possibility that a burnt odor may be generated by being mixed with the aerosol in ordinary smoking, and in such a case, the burning taste will be affected. Furthermore, regarding the uniform heating in the heating area, when the appearance of the filling of the smoking cartridge after heating was observed, it was found that the heating of the filling near the end opposite to the filter was insufficient. It was also found that there was no good heating throughout the fill.

Accordingly, an object of the present invention is to heat an aerosol-generating member composed of a filler containing an aerosol former and the like housed in a paper tube serving as an exterior base material from the outer peripheral surface of the paper tube to generate an aerosol. In a smoking cartridge of the type that sucks (gas), the heat from the outer periphery is in a state suitable for generating aerosol not only to the outer shell portion of the aerosol generating member but also to the central portion through the paper tube that is the exterior base material. To provide a smoking cartridge product which is improved so that it can be smoothly transmitted and heated as uniformly as possible, and which does not have a big problem in the strength of a paper tube after heating. Another object of the present invention is to provide a smoking cartridge product that can reduce the occurrence of scorching in the filling inside the exterior base material after heating by the peripheral heating method, and that can be expected to improve the smoking taste. .

Preferred embodiments of the smoking cartridge of the present invention are described below with reference to the drawings. However, the present invention is not limited to the following embodiments.

The smoking cartridge of the present invention is used by inserting it into a heating type smoking tool in which the heating is performed by heating the filling, which is the aerosol generating member, from the outer periphery (peripheral heating). Then, a filter member is arranged on one end side which is the mouth side during smoking, and an aerosol generating member including an aerosol former that generates an aerosol by heating with a peripheral heating method on the other end side (however, the tobacco plant is used. not included) are disposed, and the filter member and the aerosol generating member are housed inside a cylindrical exterior base material and integrated. The smoking cartridge of the present invention includes the first invention and the second invention, characterized in that, in addition to the basic structure described above, the cylindrical exterior base material has the following structure.

[First Invention]
In the first smoking cartridge of the present invention (hereinafter, also referred to as the first cartridge of the present invention), the exterior base material is a paper cylinder formed by winding paper having a thickness of 0.1 mm or more and 0.6 mm or less. At least one or more holes are provided through the paper tube in a filling portion in which the aerosol generating member is accommodated. As shown in FIGS. 1 and 2, a plurality of these through holes (hereinafter referred to as through holes) 1 are provided in a row or scattered in the paper tube that is the exterior base material 5a. It is preferable to have a configuration that As described above, conventional smoking cartridges that are used by inserting them into heating-type smoking tools that heat the outer periphery of the filling are formed of thin paper with a thickness of about 0.01 mm to 0.05 mm for the outer base material. On the other hand, one of the characteristics of the first cartridge 10 of the present invention is that the exterior base material 5 or 5a is made of thick paper having a thickness of 0.1 mm or more and 0.6 mm or less. This point also applies to the second smoking cartridge of the present invention (hereinafter also referred to as the second cartridge of the present invention), which will be described later. Hereinafter, the first cartridge and the second cartridge are collectively referred to as the cartridge of the present invention.

With the configuration as described above, the following effects can be obtained according to the first cartridge of the present invention. As described above, the paper cylinder constituting the exterior base material of the cartridge of the present invention is formed using thick paper, so it is different from the paper cylinder formed of thin paper constituting the conventional smoking cartridge. The heat transfer to the filling, which is the aerosol generating member, is inferior in comparison. Therefore, when the outer circumference is heated, the heat conduction to the central portion of the filling through the paper tube becomes poorer. On the other hand, in the first cartridge 10 of the present invention, one or more through-holes 1, preferably a plurality of through-holes 1 are provided in the paper tube whose outer circumference is heated. A difference occurs in heat conduction, and in heating the filling, which is the aerosol generating member 3 of the smoking cartridge 10, through the paper tube, the heat conduction to the central portion and the heat conduction to the outer shell portion are made uniform. As a result, unevenness in aerosol generation is reduced, and the generated aerosol can be stabilized.

More specifically, as defined in the first cartridge 10 of the present invention, when the through hole 1 is provided in the portion of the paper tube, which is the exterior base material 5 or 5a, in which the filler is accommodated, the through hole 1 is provided. Since the heat that has passed through the holes 1 is quickly transmitted to the inside of the filler 3, the heating state of the outer shell portion of the filler 3 that is in contact with the paper tube that is the outer base material 5 and the central portion of the filler 3 can be made the same. Therefore, it is preferable to provide a plurality of through holes. By providing a plurality of through-holes, more uniform and uniform heating becomes possible. At least one through-hole may be provided in the portion of the paper tube containing the filler, which is the aerosol generating member, and the position of the other through-holes is not particularly limited. As mentioned above, when the conventional product was heated and the heating state was tested, the heating of the filling near the end on the opposite side of the filter was insufficient. As shown in 1B and FIG. 2, it is preferable to provide at least one or more in the vicinity of the end portion where it has been confirmed that conventional products are insufficiently heated. For example, it is preferable to provide one or more through holes at positions 3 mm to 10 mm from the end.

Also, when a plurality of through holes are provided in the paper tube, the through holes may be arranged, for example, so as to be aligned with each other or to be scattered. Specifically, for example, as schematically shown in FIG. 1B, a plurality of through-holes may be arranged so that their horizontal positions are the same in the portion of the paper tube where the filler is stored. good. In that case, as shown in (a) and (b) of FIG. 1B, it is also preferable to provide two through-holes at positions facing each other across the center point of the paper cylinder. be. In the example of (a) shown in FIG. 1B, there are four combinations (through hole 8 holes), and two sets (four through holes) in the example of (b). Further, in the example shown in FIG. 1B(c), three through holes are arranged at equal intervals in the same horizontal position of the paper tube. The size of each through hole is not particularly limited, and for example, a hole diameter of about 0.2 mm to 0.5 mm is preferable.

When a plurality of through-holes are provided, the arrangement is not limited to arranging them at the same horizontal position of the paper tube illustrated above. As shown in FIG. 1A and FIG. It is also preferable to provide the through-holes at positions such that the through-holes are arranged spirally in the longitudinal direction when the paper tube is formed. As described above, when a plurality of through-holes are provided at the same horizontal position, there is a concern that the first cartridge may break at that horizontal position, depending on the number and size of the holes. be. Therefore, when providing a plurality of through-holes in the paper cylinder, it is preferable to design so that many through-holes do not exist at the same horizontal position.

When providing a plurality of through-holes, as shown in FIG. 1A and FIG. is also provided in the hollow part through which the generated aerosol flows when smoking, and in the part where the cooling member 2, which is devised to make the generated aerosol at a temperature suitable for smoking, is accommodated. is also a preferred form.

As described above, the first cartridge of the present invention is provided with one or more through holes in at least the portion of the paper tube containing the filler 3, which is the aerosol generating member. According to 10, the heat from the outer circumference heating is quickly transferred to the inside of the filling 3 through the through holes 1 provided in the paper tube, and the heating state of the outer shell portion and the central portion of the filling in contact with the paper tube. can be made uniform and homogenized. The first cartridge of the present invention, which is a paper tube having a thickness of 0.1 mm or more and 0.6 mm or less, and which essentially includes an exterior base material 5 or 5a having one or more through holes, has no through holes. In the case of a smoking cartridge using a paper tube having the above thickness (not shown), as described above, there is a temperature difference due to heating between the outer shell portion of the filler 3 in contact with the paper tube and the central portion far from the contact portion. As a result, the filling 3 may be heated unevenly or even partially scorched. In particular, when the thick paper tube described above is used as the exterior base material, the heat conductivity is poor, and the central portion of the filling may not be heated. If the heating temperature is raised to address this problem, the paper tube of the outer base material and part of the filling contained therein may be scorched.

As described above, the first cartridge 10 of the present invention has the through holes 1 provided in the paper tube, which is the exterior base material 5 or 5a, so that heat can be transferred more quickly to the inside of the filler 3 through the through holes 1. Therefore, it becomes possible to increase the thickness of the exterior base material 5 or 5a forming the paper tube, and the strength of the smoking cartridge can be improved. The exterior base material 5 or 5a that constitutes the first cartridge 10 of the present invention is a paper tube having a thickness of 0.1 mm or more and 0.6 mm or less, and is characterized in that the thickness of the paper is thicker than that of conventional products. do. Also, in the first smoking cartridge 10 of the present invention, by appropriately designing the number and arrangement of the through-holes 1, it is possible to realize smooth and good heat transfer to the filling 3. This demonstrates the possibility of designing the first cartridge 10 of the present invention to have the desired characteristics of aerosol generation. The method of forming the through-holes provided in the paper cylinder constituting the present invention is not particularly limited. For example, a method in which a paper material having through holes provided at desired positions is wound in a single layer or spirally to form a paper tube; A method of forming a hole having a desired size at a desired position using a laser or the like can be used.

As described above, the exterior base material 5 or 5a that characterizes the first cartridge 10 of the present invention is a paper tube that is the exterior base material 5 or 5a, and at least the aerosol-generating member of the paper tube is accommodated. The material of the paper tube is not particularly limited as long as one or more through-holes are provided in the portion of the filler. For example, any paper that has been conventionally used as tobacco paper can be used without any problem. This point is the same for the "second cartridge" provided by the second aspect of the present invention described below.

The aerosol generating member (filler) 3 including an aerosol former, which is a member other than the exterior base material 5 or 5a described above, and the filter member 4 at the mouth, which constitute the first cartridge 10 of the present invention, are provided as necessary. The cooling member 2 is not particularly limited, and any one described in the above-mentioned prior art may be appropriately used. These points are the same for the "second cartridge of the present invention" described later.

FIG. 5A shows the use of the first cartridge 10 of the present invention having the configuration shown in FIG. It is the result of examining the temporal transition of the taste factor. As shown in FIG. 5A, the temperature and flow rate remain constant, and the suction force and negative pressure each show pulses. Regarding the smoking taste, we confirmed the state of smoke concentration in the airflow.

As shown in FIG. 2(c), the first cartridge used in the test had an outer diameter of 6 mm, a total length of 75 mm, a filling length of the aerosol generating member 3 of 35 mm, a length of the filter member 4 of 17 mm, A configuration in which the hollow portion between the aerosol-generating member and the filter member was 23 mm was used. As the aerosol-generating member 3, a filling containing non-tobacco leaves and an aerosol former such as glycerin was used. The thickness of the paper cylinder in which the filler was accommodated was as thick as 0.6 mm. Then, in the first cartridge used for the test, eight through-holes with a diameter of 0.5 mm were formed at equal intervals using a laser at a position 5 mm from the end of the aerosol-generating member (Fig. 2(c) )reference).

For comparison, a smoking cartridge for comparison of the form was prepared in the same manner as described above except that no through-hole was provided for the first cartridge of the form used in the test. checked the progress. FIG. 5B is a graph of the results of examining the temporal transition of the smoking taste factor of the smoking cartridge for comparison. From a comparison between FIGS. 5A and 5B, in the case of the first cartridge 10 of the present invention, the smoke density increased from an early stage of inhalation, and the smoke density increased over a long period of time. On the other hand, in a test using a smoking cartridge for comparison, as shown in FIG. 5B, no increase in smoke density was observed in the early stages of inhalation, indicating that aerosol generation due to heating did not occur quickly. was confirmed. In addition, after the test, when observing the state of discoloration occurring in the filler and the paper tube in the portion of the aerosol-generating member after being heated, the first cartridge 10 of the present invention in which the paper tube was provided with a through-hole: It was confirmed that the tip was uniformly heated, including the vicinity of the tip. On the other hand, in the comparative smoking cartridge in which the paper tube was not provided with the through-hole, the heating in the vicinity of the tip portion was insufficient, and more burnt portions were observed than in the first cartridge 10 of the present invention. , it was confirmed that the burnt smell was also strong.

[Second Invention]
The second smoking cartridge (second cartridge) of the present invention is a paper tube in which the exterior base material is a rolled paper having a thickness of 0.1 mm or more and 0.6 mm or less. 3, the portion in which the filler, which is the aerosol-generating member, is accommodated is provided with one or more thin regions having a thickness thinner than the thickness of the paper forming the paper tube.

The thickness of the thin region, which is thinner than the thickness of the paper forming the paper tube constituting the second cartridge of the present invention, is, for example, 1/2 to 1/2 the thickness of the paper forming the paper tube. It is preferable to design so as to be about 1/6. More preferably, it should be about 1/5. Specifically, when the thickness of the paper of the paper cylinder is 0.1 mm, the thickness of the thin region is preferably about 0.02 to 0.05 mm. Further, when the thickness of the paper of the paper cylinder is 0.6 mm, it is preferable to design the thickness of the thin region to be about 0.1 to 0.3 mm. In addition, the total area of the thin region provided in the portion of the paper tube containing the filler, which is the aerosol generating member, is 10% of the total area of the paper tube containing the filler. It is preferable that it is 50% or less.

Further, the thin regions 7 or 8 constituting the second cartridge 20 of the present invention may be provided scattered at a plurality of locations as shown in FIG. As shown in 4(b), it may be provided so as to form a continuous strip. As a method of providing a continuous belt-like thin region, there are the following methods. For example, as shown in FIG. 3A, a band-shaped (tape-shaped) paper 5a (exterior base material) provided with a continuous thin region 7 in the center in the longitudinal direction is spirally wound to form a paper cylinder. A method of forming a continuous thin region 7 in a paper tube can be mentioned. Further, for example, as shown in FIG. 3B, when forming a paper tube by spirally winding a strip of paper 5a (exterior base material), the thin strip of paper 5a with a uniform thickness and winding the tape-shaped paper so that the ends in the longitudinal direction are overlapped to form a thick portion in the overlapped portion and form a continuous thin region 7 in the paper tube. .

In addition, as shown in FIG. 4(a), the thin region constituting the second cartridge 20 of the present invention is formed into a paper cylinder by winding the exterior base material 5a in a single layer, similar to conventional paper cigarettes. In this case, by using a rectangular sheet of paper in which the thin regions 7 are scattered at a plurality of locations, it is possible to obtain a paper tube having a structure in which the thin regions are scattered. Further, as shown in FIG. 4(b), when forming a paper cylinder by winding the exterior base material 5a in a single layer, by using paper in which the thin regions 8 are formed in stripes in the longitudinal direction, It is possible to obtain a paper cylinder having a plurality of thin regions 8 continuous in the longitudinal direction. In addition, although not shown in the figure, by laminating another paper continuously or in a scattered state on a part of the thin paper, the thin regions exist in a scattered state. Alternatively, it is possible to obtain a paper tube having a configuration in which thin areas are continuously present.
