- A smoking device cartridge comprising a cylindrical heated body and a mouthpiece positioned at one end of the heated body in the axial direction, which is used when attached to an induction heating type smoking device, The object to be heated is A central part comprising a first aerosol-forming substrate that extends in the axial direction and contains a first susceptor at a first content, It has an outer peripheral portion which is made of a second aerosol-forming substrate that is arranged to cover the central portion and contains a second susceptor at a second content, The second content is greater than the first content. The first aerosol-forming substrate and the second aerosol-forming substrate are formed in a strip shape, The first susceptor is made of a metal material formed in a linear or strip-like shape. The second susceptor is made of a metal material formed in a linear or strip-like shape. The mouthpiece includes a cellulose acetate filter. A cartridge for smoking accessories characterized by the following features.
Description
This invention relates to a cartridge for smoking accessories. In recent years, tobacco products that heat tobacco cartridges containing tobacco components without using a flame, allowing users to inhale the vaporized tobacco components, have become widely known. Furthermore, due to the diversification of preferences, cartridges that allow users to enjoy the aroma and flavor of plants without tobacco components, similar to tobacco but without using a flame, are also becoming known. These cartridges are used by being attached to heated tobacco devices. As heated smoking devices, for example, blade heating type and induction heating type are known. As an example of the configuration of a cartridge used in induction heating type smoking devices, Patent Document 1 is known. In the tobacco product described in Patent Document 1, a tobacco sheet (aerosol-forming substrate) containing an aerosol-forming body and susceptor particles is folded into a rod shape and wrapped in a wrapper. When this tobacco product is attached to an induction heating type smoking device and the switch is turned on, an alternating current flows through a coil built into the smoking device, generating an alternating magnetic field. As a result, an induced current flows through the susceptor particles, and the susceptor particles are inductively heated. Then, heat is transferred from the susceptor particles to the aerosol-forming body, which is heated and an aerosol is generated. Patent No. 6165275 A cross-sectional view of a cartridge for a smoking device according to this embodiment.Cross-sectional view along line II-II in Figure 1.A schematic diagram showing the first aerosol-forming substrate placed in the center of the object to be heated, as shown in Figure 2.A schematic diagram showing a second aerosol-forming substrate arranged on the outer periphery of the object to be heated, as shown in Figure 2.A schematic diagram showing part of the manufacturing process for cartridges used in smoking accessories.A schematic diagram showing a smoking cartridge installed in an induction heating smoking device. The embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a cross-sectional view of a smoking device cartridge according to this embodiment, and Figure 2 is a cross-sectional view taken along line II-II in Figure 1. As shown in Figures 1 and 2, the smoking device cartridge 1 according to this embodiment comprises a heating element 20, a mouthpiece 30, and an outer casing member 40. The heating element 20 is formed in a cylindrical shape and is arranged along the central axis C of the smoking device cartridge 1. The mouthpiece 30 is arranged alongside one end of the heating element 20 in the axial direction. The outer casing member 40 is a sheet-like material made of, for example, paper, and encloses and integrates the heating element 20 and the mouthpiece 30. Here, the smoking device cartridge 1 shown in Figure 1 is formed, for example, with a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. Of course, the smoking device cartridge 1 may be formed with dimensions other than these. The heated object 20 is formed by wrapping multiple aerosol-forming substrates 23, which are the filler material, with a sheet-like packaging member 25. The diameter of the heated object 20 is, for example, about 7 mm. The thickness of the packaging member 25 is, for example, about 1.5 mm, and the inner diameter of the packaging member 25 (the diameter of the multiple aerosol-forming substrates 23) is, for example, about 4 mm. The heated object 20 has a cylindrical central part 20a extending in its axial direction and a cylindrical outer peripheral part 20b arranged to surround the central part 20a, with the packaging member 25 surrounding the outer peripheral part 20b. The central part 20a consists of a plurality of first aerosol-forming substrates 23a. The outer peripheral part 20b consists of a plurality of second aerosol-forming substrates 23b, which are different from the plurality of first aerosol-forming substrates 23a. The diameter of the central part 20a is approximately half the inner diameter of the packaging member 25 (for example, 2 mm). The inner diameter of the outer peripheral part 20b is approximately equal to the diameter of the central part 20a, and the outer diameter of the outer peripheral part 20b is approximately equal to the inner diameter of the packaging member 25. One axial end of the heated object 20 is in contact with the mouthpiece 30. On the other hand, the other end of the heated object 20, opposite to the one end, is not covered by a lid member (e.g., paper), and the aerosol-forming substrate 23 is exposed. The packaging member 25 is made of paper, for example, but any sheet-like material is acceptable. Multiple aerosol-forming substrates 23 (first aerosol-forming substrate 23a, second aerosol-forming substrate 23b) consist of numerous components made from tobacco plants or
