Description

Cigarette filler polymer and electronic cigarette case

The present invention relates to a cigarette filler polymer obtained by polymerizing a long-shaped cigarette filler made of tobacco plants or non-tobacco plants into a bundle, and an electronic cigarette case having the cigarette filler polymer.

In recent years, in order to adapt to the smoking ban of cigarettes, electronic cigarette products have begun to spread. Instead of using flames, they smoke cigarettes that have been vaporized by heating electronic cigarette cases containing cigarette components to enjoy cigarettes. As a method of manufacturing a cigarette filler filled in such an electronic cigarette case, there is a method of pulverizing tobacco leaves into a water slurry and then turning the sheets into sheets, adding oil or glycerin to the sheets and drying them ( (See Patent Document 1: Japanese Patent Publication No. 2010-520764).

In addition, an article for smoking by inserting an electronic cigarette case and heating it is disclosed. The electronic cigarette case has a cigarette filler polymer obtained by polymerizing a cigarette filler at an end (refer to Patent Document 2: Japanese Special Table 2015 -519915). In the electronic cigarette, the heating body included in the main body of the electronic cigarette is inserted into the cigarette filler polymer to heat the cigarette filler.

In order to sufficiently generate a smoking component containing an aerosol by heating, the cigarette filler is filled at a certain filling rate or more. On the other hand, if the filling rate of the cigarette filler is increased, when the heating body included in the main body of the electronic cigarette is inserted into the polymer of the cigarette filler, the resistance is large and it is difficult to insert. In addition, if the filling rate of the cigarette filler is too high, the fluidity of the air flow inside the polymer of the cigarette filler is reduced, making it difficult for the user to inhale. Since the amount of air flow that can be inhaled is reduced, the number of cigarettes per cigarette increases. The possibility of exceeding the appropriate number of smoking. Therefore, it is required to ensure that the filling rate of the entire cigarette filler polymer is more than a fixed value, and to improve the airflow fluidity inside the cigarette filler polymer.

In addition, in the cigarette filler polymer, when the electronic cigarette case is inserted into the electronic cigarette main body or when smoking is ended and the electronic cigarette case is taken out from the electronic cigarette main body, etc., a part of the cigarette filler may come off when the user performs an operation Possibility. As a result, there is a possibility that the inside of the electronic cigarette main body will be contaminated and the electronic cigarette main body will be defective. Therefore, it is required that the cigarette filler is filled in the cigarette filler polymer in such a way that it is difficult to fall off.

Microcrystalline cellulose is obtained, for example, as a substance formed by partially depolymerizing α-cellulose obtained from the bulbs of fibrous plants with acid, for example, and the soluble portion is removed from cellulose and the insoluble portion is appropriately crystallized And got it.

As a result of various studies, the following is known about the cigarette filler 20 containing non-tobacco plants, aerosol precursors, and microcrystalline cellulose. If the cigarette filler 20 is placed under dry conditions, even if the filler containing the non-tobacco plant and the aerosol precursor loses water, the cellulose crystallites will maintain the structure of the filler and suppress volume shrinkage, etc. Structural changes. Such effects are obtained by using microcrystalline cellulose.

The microcrystalline cellulose can maintain the state of the powder, or can be dispersed in a solvent such as water and input as a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used for dispersion into the solvent.

The standard of the added amount of microcrystalline cellulose is that the content of the cigarette filler 20 is 1% or more and 15% or less. It is preferably 3% or more and 12% or less, and more preferably 5% or more and 10% or less.

The addition of microcrystalline cellulose is effective for improving the moldability, improving the workability during kneading by a roller crusher, etc., and particularly suppressing the shrinkage and volume change of the cigarette filler 20, and is also effective in the electronic cigarette case 1 The quality management and sense of homogeneity of use are effective.

The average particle diameter of the microcrystalline cellulose used in the present invention is preferably 30 μm to 200 μm, more preferably 50 μm to 150 μm, and still more preferably 70 μm to 120 μm.

When the average particle diameter of the microcrystalline cellulose is 30 μm or more, the effect of suppressing the shrinkage of the cigarette filler 20 is excellent, and when the average particle diameter of the microcrystalline cellulose is 150 μm or less, the moldability can be improved in addition to the above-mentioned shrinkage suppression effect. good.

The average particle size of microcrystalline cellulose is determined by a sieving method. The above average particle diameter can be obtained by the method described in JIS K 0069:1992. In addition, the average particle diameter refers to the diameter of the test results performed by a plurality of sieves, for example, the mass is accumulated from the larger sieve hole, and corresponds to 50% of the mass. Furthermore, preferably, the mass of the residue after passing through the 250 μm sieve accounts for 8% or less of the total mass of the microcrystalline cellulose subjected to sieving, and the mass of the residue after passing through the 75 μm sieve accounts for the microcrystalline fiber subjected to sieving. More than 45% of the total mass of the element.

When the mass of the residue after passing through the 250 μm sieve accounts for 8% or less of the total mass of the microcrystalline cellulose subjected to the screening, the screened microcrystalline cellulose has the effect of suppressing the shrinkage of the cigarette filler 20. When the mass of the residue after passing through the 75 μm sieve accounts for 45% or more of the total mass of the microcrystalline cellulose subjected to sieving, the formability of the cigarette filler 20 can be improved.

The mass average molecular weight (Mw) of microcrystalline cellulose is preferably 10,000 or more and 200,000 or less. More preferably, it is 10,000 or more and 100,000 or less. If it is 10,000 or more, the effect of suppressing the shrinkage of the cigarette filler 20 is excellent, and if it is 100,000 or less, the moldability can be improved in addition to the effect of suppressing the shrinkage. It is particularly preferably 20,000 or more and 60,000 or less. The molecular weight of cellulose can be measured by gel permeation chromatography (GPC). For example, a measurement method as described in Japanese Patent Laid-Open No. 6-109715 can be used, and polyethylene glycol or the like can be suitably used as a standard material.

The manufacturing process of the cigarette filler 20 will be described. The manufacturing process of the cigarette filler 20 includes: a drying and crushing process of drying, crushing, and weighing the non-tobacco plant as the main raw material; a preparation process such as weighing and pre-processing of other raw materials; mixing raw materials to form a combination Mixing procedures for materials; and filling shaping procedures for shaping the composition.

In the dry pulverization process, in order to form a composition of the use site (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.) of the non-tobacco plant as the main raw material, a predetermined pulverized product is processed. At this time, it is preferable to adjust to an appropriate water content in order to absorb or carry other components such as an aerosol precursor and water added afterwards. In the drying procedure, the temperature is preferably 60°C or more and 80°C or less. By adopting this range, it is possible to prevent the required fragrance from being dispersed, and it is easy to achieve the desired water content. In addition, when it is 65° C. or higher, the desired water content can be more easily achieved, and when it is 75° C. or lower, the desired fragrance can be further prevented from being dispersed.

It is preferable that the water content of the dried and pulverized composition is 5% or less of the total mass of the dried and pulverized composition. By doing this, pulping will become easier in subsequent procedures. More preferably, the water content of the composition after drying and grinding is 3% or less of the total mass of the composition after drying and grinding. In addition, if the water content of the composition after drying and pulverization is 0.1% or more of the total mass of the composition after drying and pulverization, it is possible to maintain a state of good affinity with water and the like. Furthermore, a sieving program for sieving the pulverized product can also be provided in the drying and pulverizing process, so that it can be adjusted to a desired particle size and be put into the mixing process.

In the preparation procedure, the raw materials required when preparing the cigarette filler 20 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation procedure and put into the mixing procedure.

In the mixing procedure, a general mixer can be used. For example, it is preferable to adopt a form in which a stirring blade is used to apply a shearing force to the raw materials in the mixing tank to mix.

In the filler forming procedure, after the composition obtained by mixing various raw materials is formed into a thin sheet shape, the cigarette filler 20 is formed by cutting. In this embodiment, in order to form a thin sheet, three roller crushers are prepared. When using three roller crushers, it is preferable to perform kneading, dispersion, etc. by the compression due to being pressed into the narrow rollers and the shearing due to the difference in roller speed, and the desired shape can be formed by the scraper The thickness of the sheet. In addition, it can also be produced using a press roll or a press.

In the filler forming process, other methods such as forming the composition through the orifice plate by pressurization may also be used. In addition, in the filler forming process, non-tobacco plants, aerosol precursors, adhesives or thickeners, flavor additives, preservatives, etc. may be further added as needed, and water or the like may also be added.

In the present embodiment, it is preferable to use water that has been sterilized or microorganisms removed, and it is preferable to use pure water obtained by reverse osmosis membrane, ion exchange, or the like.

The thickness of the sheet obtained by the filler forming procedure is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut to a predetermined width by a cutter, a rotary cutter of a rotary knife system, or the like.

In the present embodiment, an example of cutting a sheet with a thickness of 0.3 mm will be described. First, the formed sheet is cut into a rectangle with a length of 150 mm and a width of 240 mm, for example. This rectangular sheet was fed to a rotary cutter and cut into a shape of 1.5 mm in length and 240 mm in width to obtain a cut sheet material. Thus, the dimension a of the cigarette filler 20 in the longitudinal direction is 1.5 mm, and the dimension b in the short direction is 0.3 mm. Fifty cut pieces of the sheet were wound around the package 25 to form a wound article having an outer shape of about 6.9 mm. The wound product was cut into a length of 12.0 mm with a cutter, and a cigarette filler polymer 10 can be obtained. The mass of the cigarette filler polymer 10 was 0.29 g. When the ratio of the volume of the cigarette filler 20 to the volume of the cigarette filler polymer 10 is defined as the volume filling rate, the volume filling rate of the cigarette filler polymer 10 of the present embodiment is approximately 0.60. In addition, the density of the cigarette filler polymer 10 is 1.07 g/cm ³ .

Thereby, the cigarette filler 20 having the elongated shape of the cigarette filler polymer 10 is polymerized into a bundle shape along the longitudinal direction.

The arrangement state of the cigarette filler 20 of the cigarette filler polymer 10 will be described in detail. FIG. 4 shows a front view of the cigarette filler polymer 10. FIG. 4 shows a typical arrangement example of the cigarette filler 20. In the cigarette filler polymer 10, the cigarette filler 20 is in a dense state in contact with the package 25 or other cigarette filler 20.

Among the cigarette fillers 20, the cigarette filler 20 at the outermost peripheral portion in contact with the package 25 is oriented substantially in the circumferential direction toward the longitudinal direction. In FIG. 4, one of the long sides of the cigarette filler 20 a is in contact with the package 25 as a whole. In addition, the two short sides of the cigarette filler 20a are in contact with the cigarette fillers 20b and 20c adjacent in the circumferential direction, respectively. The long sides of the cigarette fillers 20b and 20c also contact the package 25, respectively. Similarly, the cigarette fillers 20 located at the outermost peripheral portion are all along the circumferential direction toward the long side direction, and are in contact with each other on the short side. As a result, in the outermost peripheral portion, the filling rate of the cigarette filler 20 is high, and the positions of the cigarette fillers 20 hardly shift due to the mutual contact with each other in the circumferential direction.

Among the cigarette fillers 20, many of the cigarette fillers 20 that are in contact with the inner peripheral side of the cigarette filler 20 in the outermost portion are oriented substantially in the circumferential direction in the longitudinal direction. In FIG. 4, one of the long sides of the cigarette filler 20 d on the outer peripheral side is in contact with the cigarette filler 20 a at the outermost portion, and the long-side direction is substantially along the circumferential direction. Although the longitudinal direction of a part of the cigarette filler 20e is along the radial direction as shown in the cigarette filler 20e, the longitudinal direction of the cigarette filler 20 in contact with the inner peripheral side of the cigarette filler 20 at the outermost peripheral portion is substantially along the circumferential direction The number of cigarette fillers 20 is greater than the number of cigarette fillers 20 in the longitudinal direction along the direction other than the circumferential direction. Therefore, in a region close to the outermost peripheral portion, the filling rate of the cigarette filler 20 is also high, and the position of the cigarette filler 20 is hard to shift.

The surface of the cigarette filler 20 in the longitudinal direction is in contact with the surface of the adjacent cigarette filler 20 in the longitudinal direction, or the surface in the longitudinal direction is in contact with the surface of the adjacent cigarette filler 20 in the short direction. As described above, in the outer peripheral portion, the surface of the cigarette filler 20 in the longitudinal direction is often in contact with the surface of the adjacent cigarette filler 20 in the short direction, but as a whole, the surface in the longitudinal direction is adjacent to the adjacent The surface of the cigarette filler 20 in the longitudinal direction is often in contact. Therefore, in the center of the cigarette filler polymer 10, many of the cigarette fillers 20 form a filler group 21 in which the longitudinal surfaces contact each other.

A plurality of filler groups 21 are formed in the cigarette filler polymer 10, and in each filler group 21, the long side of the cigarette filler 20 and the long side of the adjacent cigarette filler 20 are in contact with each other. Since the cigarette fillers 20 in the filler group 21 are in contact with each other on the long side, there is not much gap, but it is easy to form a void 22 between the filler groups 21. In the outer peripheral portion of the cigarette filler polymer 10, the cigarette filler 20 is substantially along the circumferential direction as described above, so it is difficult to form the void portion 22, and in the central portion of the cigarette filler polymer 10, in the filler group 21 The gap 22 is easily formed between. In the cross section of the cigarette filler polymer 10 orthogonal to the longitudinal direction, the porosity of the central region α as the central region obtained by dividing the area in the radial direction is higher than the void of the peripheral region β as the peripheral region rate.

Since the cigarette filler 20 has a long-side direction and a short-side direction in a cross section perpendicular to the longitudinal direction, the above-mentioned configuration makes it easy to realize the following two arrangements at the same time. 1) The cigarette filler 20 in the outermost portion Arrangement along the circumferential direction; 2) Arrangement of the filler group 21 and the void portion 22 having the cigarette filler 20 in the central portion.

Since the porosity of the central region α is high, it is easy to insert the heating portion 50 included in the electronic cigarette body 2 into the cigarette filler polymer 10. In addition, the air flow containing the aerosol generated by the heating of the heating portion 50 can easily flow in the cigarette filler polymer 10. On the other hand, since the porosity of the peripheral region β is low, the overall filling rate of the cigarette filler polymer 10 can be increased, and a sufficient amount of aerosol can be generated.

In addition, since the filling rate of the outer peripheral region β is high, the cigarette filler polymer 10 can structurally hold the cigarette filler 20 firmly. Therefore, when the user performs the operation, the fall of the cigarette filler 20 can be reduced.

The arrangement of the cigarette filler 20 changes according to the degree of winding by the package 25, and therefore it is different for each one. FIG. 5 shows a front view of another cigarette filler polymer 10. As shown in this figure, a part of the cigarette filler 20 disposed at the outermost peripheral portion may be directed in a direction other than the circumferential direction. However, even in this case, in the outermost peripheral portion, the number of cigarette fillers 20 in the longitudinal direction substantially along the circumferential direction is larger than the cigarettes in the direction other than the longitudinal direction substantially along the circumferential direction The number of fillers 20 can obtain the same effect as in the case of FIG. 4. The same is true for the cigarette filler 20 that is in contact with the inner peripheral side of the cigarette filler 20 in the outermost portion. In addition, although the arrangement of cigarette fillers 20 arranged more centrally than this is different from FIG. 4, it is different from FIG. 4 in that many filler groups 21 are formed and voids 22 are formed between the filler groups 21. Is the same. Thus, in the state of FIG. 5, the porosity of the central region α is relatively higher than the porosity of the peripheral region β.

When the user inhales while the cigarette filler polymer 10 is being heated by the heating unit 50, the air flow containing the aerosol flows toward the mouthpiece 14 side. As described above, the porosity of the central region α is higher than the porosity of the peripheral region β, so the airflow is collected from the outer peripheral side to the central side and flows in the longitudinal direction. In this case, a large amount of aerosol is generated from the outer peripheral portion with a high filling rate, which can flow smoothly.

FIG. 6 shows a front view showing the procedure for winding the cigarette filler 20 from the package 25. FIG. As shown in FIG. 6( a ), when winding the cigarette filler 20, first, the cigarette filler 20 is placed on the package 25. The package 25 is placed on the opening and closing portion 41 provided on the base 40. The opening/closing part 41 can move in a direction to separate from each other. At this time, it is desirable to place the cigarette filler 20 so that the long side of the cigarette filler 20 contacts the package 25 as much as possible.

Next, as shown in FIG. 6( b ), the opening and closing parts 41 are moved away from each other to form a recess 42 into which the packaging body 25 falls, and the cigarette filler is wrapped with the packaging body 25 falling into the recess 42 20. Finally, as shown in FIG. 6(c), the package 25 is closed to form the cigarette filler polymer 10. In the procedure of wrapping by the package 25, by adjusting the speed or the like, it is possible to arrange a large number of cigarette fillers 20 in the outermost peripheral portion substantially along the circumferential direction. In addition, during the period in which the cigarette filler 20 is wrapped by the package 25 and closed, by adjusting the force for pressing the cigarette filler 20 into the package 25, the porosity of the central region α can be set to an appropriate range.

The arrangement of the cigarette filler 20 described here is brought about by the following: the cross-sectional shape of the cigarette filler 20 formed into an elongated shape is a substantially rectangular shape having a long side direction and a short side direction, and an outermost peripheral portion The majority of cigarette fillers 20 and adjacent cigarette fillers 20 are arranged substantially along the circumferential direction. The applicant of the present application changed the shape or arrangement of the cigarette filler 20, and verified the amount of aerosol and the number of inhalable aerosols that can be inhaled through one experiment through experiments. The conditions and results are shown in Table 1. Condition 1 is that the cross-sectional shape of the cigarette filler 20 is set to a square (0.60±0.10 mm in length and 0.60±0.10 mm in width). Conditions 2 to 6 are that the cross-sectional shape of the cigarette filler 20 is set to be rectangular (1.50±0.10 mm in length and 0.28±0.02 mm in width). Condition 2 is the technical solution of this embodiment.

(Table 1)

From the viewpoint of the amount of aerosol and the number of puffs, conditions 2, 3, and 5 are preferable. In addition, the ease of inserting the heating portion 50 of the electronic cigarette body 2 into the cigarette filler 20 is good under the conditions 2 and 3.

In the conditions 2 to 6, the arrangement of the cigarette filler 20 differs depending on the arrangement of the cigarette filler 20 before the package 25 is wound or the manner in which the package 25 winds the cigarette filler 20. The cigarette filler 20 is most easily wound under the condition 2 which is the technical solution of the present embodiment, and the second conditions 3 and 5 are the technical solution that the cigarette filler 20 is easily wound. Conditions 4 and 6 are technical solutions that make it difficult to wind the cigarette filler 20. Therefore, from the viewpoint of ease of manufacturing, the conditions 2, 3, and 5 are preferable, and the condition 2 is particularly preferable.

Under Condition 1 in which the cross-sectional shape of the cigarette filler 20 is square, it is difficult to shape the shape of the cigarette filler 20 in this way, and the cigarette filler 20 is more likely to come off than in the case of a rectangular cross-sectional shape. Moreover, the amount of air flow generated during heating is also small.

As described above, from the viewpoint of ease of manufacturing and both of the air flow rate and the number of puffs, Condition 2 as the technical solution of the present embodiment can be said to be the most preferred technical solution.

FIG. 7 shows a front view of the support member 12.

The support member 12 may have other shapes. As shown in FIG. 7( b ), it may have four circumferential edge portions 34 that protrude in the radial direction from the central portion, and the flow path portion 35 is formed between the circumferential edge portions 34. In addition, as shown in FIG. 7( c ), the flow path portion 37 may be formed on the center side of the peripheral edge portion 38, and the flow path portion 37 may be divided into two parts by the partition wall portion 39. In either case, the peripheral edge portion of the support member 12 can be in contact with the packaging member 16 on the outer peripheral surface, and can be in contact with the cigarette filler 20 in the longitudinal direction on the end surface.
