Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)
FIG. 1 is a cross-sectional view of a cartridge 1 for smoking equipment according to the first embodiment of the present invention. As shown in FIG. 1, the smoking equipment cartridge 1 according to the first embodiment includes a heated body 20, a support member 30, and a mouthpiece 40. The heated body 20, the support member 30, and the mouthpiece 40 are arranged side by side on the central axis C1. The heated body 20, the support member 30, and the mouthpiece 40 are wound and integrated by a sheet-shaped exterior member 10. The exterior member 10 is made of, for example, paper.

Here, the smoking equipment cartridge 1 shown in FIG. 1 is formed, for example, having a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. Further, the heated body 20 has a length of 10 to 25 mm. Of course, the cartridge for smoking equipment may be formed in other dimensions.

The body 20 to be heated is formed by winding an aerosol-forming base material 23, which is a filling material, around a sheet-shaped packaging member 25 to form a cylindrical shape, and the aerosol-forming base material 23 is exposed at both ends thereof. That is, both ends of the heated body 20 are not covered with a lid member (for example, paper). The packaging member 25 is made of, for example, paper, but the material may be any as long as it is a sheet-shaped member.

The aerosol-forming base material 23 is composed of a smoking material made from a tobacco plant or a non-tobacco plant, which will be described in detail later. The aerosol-forming base material 23 is, for example, configured by bundling strip-shaped members, and is arranged so that its longitudinal direction is along the central axis C1.

When the aerosol forming base material 23 is composed of a strip-shaped member, the cross section orthogonal to the central axis C1 is substantially rectangular, and the ratio of the long side to the short side of the cross section is, for example, 1.5: 1 to 30 :. It is preferably in the range of 1. Further, it is preferable that the length of the aerosol-forming base material 23 is substantially the same as the length of the object to be heated 20. To give an example of the dimensions of the aerosol-forming base material 23, the long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

Of course, the aerosol-forming base material 23 is not limited to the strip-shaped member. For example, it may be a rod-shaped member or a powdery granular member. Further, the aerosol forming base material 23 is a combination of a strip-shaped member and a powder-granular member, a combination of a strip-shaped member and a rod-shaped member, a combination of a rod-shaped member and a powder-granular member, or a strip-shaped member. It may be configured by a combination of a rod-shaped member and an aerosolized member. In these cases, it is preferable that at least a part of the raw materials of each member is different because the aroma and taste are improved.

The mouthpiece 40 is a portion constituting the mouthpiece of the cartridge 1 for smoking equipment, and is formed by using, for example, paper or the like. Further, the mouthpiece 40 may include a cellulose acetate filter or the like for removing fine particles. A part of the water vapor generated by the heated body 20 and the fine particles in the aerosol is filtered by the filter of the mouthpiece 40.

The support member 30 includes a first wall portion 31 and a shaft portion 34. The support member 30 is made of, for example, silicone, and the first wall portion 31 and the shaft portion 34 are integrally formed. Of course, both may be formed separately. When the shaft portion 34 is provided separately from the first wall portion 31, for example, a rolled paper or a crimped polymer sheet can be used as the configuration of the shaft portion 34.

The first wall portion 31 is formed in a disk shape. The diameter of the first wall portion 31 is substantially equal to the diameter of the aerosol-forming substrate 23. Here, "substantially equal" means the case where the diameter is equal to the diameter of the aerosol-forming base material 23 and the dimension including the thickness of the packaging member 25 in the diameter of the aerosol-forming base material 23, that is, the diameter of the heated body 20. It is a concept that includes equal cases. The diameter of the first wall portion 31 may be smaller than the diameter of the aerosol-forming base material 23. The first wall portion 31 is arranged at a position facing the aerosol-forming base material 23, and the end face of the first wall portion 31 is in contact with the end portion (end face) of the aerosol-forming base material 23.

The shaft portion 34 is formed in a columnar shape. The shaft portion 34 extends from the first wall portion 31 coaxially with the central axis C1 toward the mouthpiece 40. The end portion 34a of the shaft portion 34 is in contact with the end surface of the mouthpiece 40.

The first wall portion 31 abuts on the aerosol-forming base material 23, and the end portion 34a of the shaft portion 34 abuts on the mouthpiece 40, thereby restricting the axial movement of the aerosol-forming base material 23.

FIG. 2 is a cross-sectional view taken along the line II-II of the first wall portion 31 shown in FIG. As shown in FIG. 2, the first wall portion 31 has a plurality of (four in this embodiment) through holes (first through holes) 32. The four through holes 32 are arranged at equal intervals (90 degree intervals) along the circumferential direction. These four through holes 32 form a first flow path through which the aerosol generated by heating the aerosol-forming base material 23 flows. The diameter of the through hole 32 is a size suitable for the aerosol to flow.

Further, the space S1 between the shaft portion 34 and the exterior member 10 is a flow path through which the aerosol flows. The space S1 functions as an alternating current portion where the aerosol flowing through each through hole 32 interacts, and also functions as a cooling portion for cooling the aerosol. That is, the support member 30 guides the aerosol generated by the heated body 20 to the mouthpiece 40. At that time, the aerosol is exchanged and cooled by the space S1 between the shaft portion 34 and the exterior member 10, and is sucked into the smoker's mouth through the mouthpiece 40.

Here, the thickness of the first wall portion 31 can be in the range of about 1/3 to 1/10 of the length of the shaft portion 34. This is because the strength of the support member 30 can be ensured while having the effects of alternating current and cooling of the aerosol by the space S1.

Next, a specific example of the raw material used as the aerosol forming base material 23 will be described. The aerosol-forming substrate 23 is composed of any one or a plurality of combinations of the raw materials shown below.

It has a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition.

In the drying / crushing step, since the part of the tobacco plant or non-tobacco plant used as the main raw material (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.) is used as a composition, it is processed into a predetermined crushed product. .. At that time, it is preferable to adjust the amount of water to be convenient for absorbing or supporting the aerosol former, water and other components to be added later. In drying, the temperature is preferably 60 ° C. or higher and 80 ° C. or lower. Within this range, it is easy to reach the desired water content while avoiding the dissipation of the required flavor component. Further, the drying / crushing step may be provided with a sieving step for sieving the crushed product, and the pulverized product can be adjusted to a desired particle size and put into the mixing step.

In the preparation step, the raw materials necessary for producing the aerosol-forming base material 23 can be prepared. The microcrystalline cellulose described above is weighed in the preparatory step and charged into the mixing step.

In the mixing step, a normal mixer can be used. For example, a form in which the raw materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used.

In the filler forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form a strip-shaped or rod-shaped aerosol-forming base material 23. In this embodiment, a three-roll mill is prepared to make a thin sheet. By using a three-roll mill, it is possible to obtain a sheet of a desired thickness by a doctor blade while performing kneading, dispersion, etc. by compression by being pushed between narrow rolls and shearing by a difference in roll speed. preferable. It can also be manufactured using a press roller or a press machine.

Further, in order to obtain a powdery or granular aerosol-forming substrate 23, it is preferable to appropriately grind or classify the above composition. The average particle size of the powdery or granular aerosol-forming substrate 23 is preferably, for example, 0.1 to 3.0 mm, more preferably 0.5 mm or less. The average particle size is determined by, for example, the sieving method described in JIS K 0069: 1992. That is, this average particle diameter refers to a diameter corresponding to 50% of the mass obtained by integrating the masses of the test results using a plurality of sieves from the one having the largest opening. Further, the particle size at an integrated value of 50% in the particle size distribution obtained by the laser diffraction / scattering method may be used as the average particle size.

In the filling molding step, other means such as molding the composition by passing it through an orifice by pressurization may be used. Further, in the filling molding step, if necessary, flavor additives and preservatives such as non-tobacco plants, aerosol formers, binders or thickeners may be further added, or water or the like may be added. Is also good.

The thickness of the sheet obtained in the filler molding step is preferably in the range of 0.1 mm to 1.0 mm, 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 blade type rotary cutter, or the like.

Here, the case of imparting adhesiveness to the surface of the aerosol-forming base material 23 is not particularly limited as long as it is a means capable of imparting adhesiveness, but the above-mentioned binder may be attached to at least a part thereof. By imparting adhesiveness, when the strip-shaped or rod-shaped aerosol-forming base material 23 is combined with the powder-shaped or granular aerosol-forming base material 23, the surface of the strip-shaped or rod-shaped aerosol-forming base material 23 is powdered or powdered. The granular aerosol-forming base material 23 can be stably held.
