Definitions

  • the present invention relates to a tobacco filler assembly obtained by accumulating long tobacco fillers formed of a tobacco plant or a non-tobacco plant in a bundle and an electronic cigarette cartridge having the same.
  • an electric cigarette product for enjoying tobacco by heating an electronic cigarette cartridge containing a tobacco component without using a flame so as to inhale a vaporized tobacco component is beginning to spread.
  • a manufacturing method of a tobacco filler filing the electric cigarette cartridge there is a method of powdering a tobacco leaf, making the powdered tobacco leaf into an aqueous slurry, forming the aqueous slurry into a sheet, adding oil or glycerin to the sheet, and drying the sheet (refer to Patent Literature 1).
  • Patent Literature 2 an article which is smoked by inserting an electronic cigarette cartridge having a tobacco filler assembly, in which a tobacco filler is accumulated, at an end portion so as to heat the electronic cigarette cartridge.
  • a heating body having an electronic cigarette body is inserted into a tobacco filler assembly, and thus, the tobacco filler is heated.
  • Filling of a tobacco filler is performed at a certain filling rate or more in order to sufficiently generate an inhalation component including an aerosol by heating.
  • the filling rate of the tobacco filler increases, when a heating body provided in an electronic cigarette body is inserted into a tobacco filler assembly, a resistance increases, and the insertion is difficult.
  • the filling rate of the tobacco filler is too high, fluidity of an air flow inside the tobacco filler assembly decreases, and thus, it difficult for a user to inhale.
  • an amount of the air flow which can be inhaled at one time decreases, the number of smoke inhalations per cigarette increases, and there is a possibility that the number of proper smoke inhalations is exceeded. For this reason, it is required to improve the fluidity of the air flow inside the tobacco filler assembly while securing a certain filling rate or more for the tobacco filler assembly as a whole.
  • the tobacco filler assembly when handling of the user is performed such as when the electronic cigarette cartridge is inserted into the electronic cigarette body or when the electronic cigarette cartridge is extracted from the electronic cigarette body after the smoking is finished, there is a possibility that a portion of the tobacco filler falls. Accordingly, an inside of the electronic cigarette body may be soiled, and thus, there is a possibility that a failure of the electronic cigarette body occurs. Therefore, it is required to fill the tobacco filler assembly with the tobacco filler such that the tobacco filler does not easily drop out.
  • the present invention is made in consideration of the above-described problems, and an object thereof is to provide a tobacco filler assembly and an electronic cigarette cartridge which improve the fluidity of the air flow inside the tobacco filler assembly while securing a certain filling rate or more for the tobacco filler assembly as a whole, are easily inserted into the electronic cigarette body, and does not allow the tobacco filler to easily drop out.
  • a tobacco filler assembly which is obtained by accumulating long tobacco fillers in a bundle and whose outer peripheral portion is wound with a sheet-shaped package, in which each tobacco filler is formed such that a dimension in a long side direction is longer than a dimension in a short side direction in a cross section orthogonal to a length direction, and a long side direction of a tobacco filler of an outermost peripheral portion in contact with the package is directed in a direction approximately along a circumferential direction or the long side direction of the tobacco filler is directed in a direction other than the direction approximately along the circumferential direction, and the number of tobacco fillers whose long side directions are directed in the direction approximately along the circumferential direction is larger than the number of tobacco fillers whose long side directions are directed in the direction other than the direction approximately along the circumferential direction.
  • a filling rate of the tobacco fillers in the outer peripheral portion is high, a filling rate of the tobacco fillers in a center portion is relatively low, and thus, it is possible to insert a heating unit of an electronic cigarette body into the tobacco filler assembly while securing an amount of the tobacco fillers.
  • the tobacco fillers in the outer peripheral portion form a rigid structure, and thus, it is possible to allow the tobacco filler not to easily drop out when the electronic cigarette cartridge is handled.
  • a porosity of the central-side region is higher than that of the outer peripheral-side region.
  • the heating unit of the electronic cigarette body is easily inserted into the tobacco filler assembly, and it is possible to improve the fluidity of the air flow.
  • the number of tobacco fillers whose long side directions are directed in the direction approximately along the circumferential direction is larger than the number of tobacco fillers whose long side directions are directed in the direction other than the direction approximately along the circumferential direction.
  • the long side direction of the tobacco filler which is positioned on a second turn from the outermost periphery, is also approximately along the circumferential direction. Therefore, it is possible to increase the filling rate in the outer peripheral portion, and it is possible to further strengthen the structure of the tobacco filler to suppress dropping out of the tobacco filler while sufficiently securing the amount of the tobacco fillers.
  • a surface in the long side direction of the tobacco filler is in contact with a surface in a long side direction of an adjacent tobacco filler or is in contact with a surface in a short side direction of the adjacent tobacco filler, and the number of the tobacco fillers whose surfaces in the long side direction are in contact with the surfaces in the long side directions of the adjacent tobacco fillers is larger than the number of the tobacco fillers whose surfaces in the long side direction are in contact with the surfaces in the short side directions of the adjacent tobacco fillers.
  • a filler group in which the tobacco fillers overlap each other on the long sides is formed, and thus, a void portion can be formed between the filler groups.
  • the tobacco filler is formed of a non-tobacco plant.
  • an electronic cigarette cartridge including: the above-described tobacco filler assembly; a support member which is adjacent to the tobacco filler of the tobacco filler assembly in a length direction and through which an air flow along the length direction passes; and a mouthpiece.
  • the air flowing through the void portion of the tobacco filler assembly smoothly flows to the mouthpiece via the support member, and thus, a user can inhale an appropriate amount of air.
  • the support member has a support portion in at least an outermost peripheral portion, and the support portion is adjacent to the tobacco filler of the outermost peripheral portion, which is in contact with the package, in the length direction.
  • the support portion and the tobacco filler of the outermost peripheral portion are in contact with each other and are approximately along the circumferential direction, and thus, the tobacco filler of the outermost peripheral portion forming a rigid structure is supported by the support member in the length direction, and when the heating unit is inserted or the like, it is possible to prevent the tobacco filler from collapsing and dropping out.
  • a filling rate in an outer peripheral portion is high, and the filling rate for the tobacco filler assembly as a whole can increase. Accordingly, it is possible to sufficiently generate aerosol and improve a fluidity in a center portion, air easily flows, and thus, it is possible to appropriately set an amount of air flow and the number of inhalation in an electronic cigarette cartridge.
  • a porosity of the center portion is high, and thus, an insertion to the electronic cigarette body can be easily realized.
  • a rigid structure is formed by tobacco fillers along a circumferential direction in the outer periphery portion, and thus, it can be made difficult for the tobacco filler to drop out.
