Definitions

  • the present invention belongs to the technical field of heated cigarettes and in particular relates to a double-layer heated cigarette, and a preparation method and use thereof.
  • the heated non-burning cigarette produces smoke from the smoking section of the heated cigarette, which has a good acceptance of the taste of the smoke.
  • the commercialized heated non-burning cigarette mainly includes the smoking section, the hollow support section, the cooling section and the filter tip section.
  • the forms of tobacco in the smoking section include: reconstituted tobacco leaf flakes, cut tobacco, granular tobacco substances, block tobacco substances, etc. filled in order or disorder.
  • the essence, spice and smoke agent loaded on the tobacco are evaporated to produce smoke.
  • the inventor found that the existing technology usually uses tobacco particles to fill the smoking particle segment of the cigarette or cigarette cartridge with cigarette particles, for example, the end of the smoking particle segment far away from the lip is sealed by a sealing film/sealing sleeve and the other end is sealed by a perforated sealing piece.
  • This setting will bring some problems: in order to facilitate the filling of tobacco particles, the granular cigarette directly uses an empty tube as the outermost drum.
  • the sealing film/sealing sleeve is fixed on the end of the empty tube of the cigarette by the adhesive or extrusion. The side end of the sealing film/sealing sleeve is exposed to the outside.
  • US 2019 0 373 948 A1 discloses a cigarette structure for heat-not-burn cigarettes comprising: an envelope that is cylindrical and hollow, a cleaning isolation sleeve disposed at a front end of the envelope, and a smoking article zone and a cooling and filtration zone sequentially disposed in the envelope.
  • the first aspect of the present invention provides a double-layered heated cigarette including an empty tube 2 and an aesthetic paper layer 3 wrapped on the outer layer of the empty tube 2, an end of the empty tube 2 far away from the lip being sealed with a sealing piece 1, and a lateral end of the sealing piece 1 being wrapped by the aesthetic paper layer 3.
  • the inside of the empty tube 2 includes a smoking segment 4, a limiting segment 5, a hollow cooling segment 7, and a filter segment 8 in sequence from the end far away from the lip to the end in contact with the lip.
  • the inside of the smoking segment 4 includes granular smoke-emitting substances.
  • the sealing piece 1 is a puncturable sealing film, a breathable sealing film, a puncturable sealing sleeve or a breathable sealing sleeve; or a heat generating element insertion hole is arranged in the sealing piece 1; or a gas hole is arranged in the sealing piece 1.
  • At least two rows of vent holes are arranged on the empty tube 2 and the aesthetic paper layer 3 axially corresponding to the hollow cooling section 7 to connect a hollow cavity of the hollow cooling section 7 with the outside.
  • the limiting segment 5 is a perforated cylinder
  • the hollow cooling segment 7 is a cavity
  • the filter segment 8 is a polymer fiber tow segment.
  • the second aspect of the invention provides the use of the double-layer heated cigarette according to the first aspect for avoiding fall-off of the sealing piece 1.
  • the third aspect of the invention provides a method of preparing the double-layer heated cigarette according to the first aspect, including the steps of: sealing a sealing piece 1 at an end far away from the lip of an empty tube 2 and then wrapping an aesthetic paper layer 3 at the outermost layer such that a lateral end of the sealing piece 1 is wrapped by the aesthetic paper layer 3.
  • the aesthetic paper layer is wrapped on the outer layer of the empty tube and the aesthetic paper layer wraps the lateral end of the sealing piece 1, at the moment, the lateral end of a sealing film/sealing sleeve is not exposed to the outside, which prevents the sealing film/sealing sleeve from falling off the empty tube when the lateral end of the sealing film/sealing sleeve is forced during transport or filling of the cigarette.
  • the cigarette empty tube is generally a stiffer paper tube and cannot be printed with a pattern. After the outer layer of the empty tube is wrapped with the aesthetic paper layer, the pattern is easily printed and the cigarette becomes more aesthetic.
  • a list of reference signs 1, sealing piece, 2, empty tube, 3, aesthetic paper layer, 4, smoking segment, 5, limiting segment, 6, vent hole, 7, hollow cooling segment, 8, filter segment.
  • a plurality means two or more.
  • the orientation or state relationship indicated by the terms “inside”, “up”, “down”, etc. is based on the orientation or state relationship shown in the attached drawings. It is only for the convenience of describing the invention and simplifying the description, but not for indicating or implying that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore cannot be interpreted as limiting the present invention.
  • connection can be fixed connection, removable connection, or integrated connection; the connection can be mechanical connection or electrical connection; the connection can be direct connection or indirect connection through an intermediate medium.
  • a double-layer heated cigarette including an empty tube 2 and an aesthetic paper layer 3 wrapped on the outer layer of the empty tube 2, an end of the empty tube 2 far away from the lip being sealed with a sealing piece 1, and a lateral end of the sealing piece 1 being wrapped by the aesthetic paper layer 3.
  • the inside of the empty tube 2 includes a smoking segment 4, a limiting segment 5, a hollow cooling segment 7, and a filter segment 8 in sequence from the end far away from the lip to the end in contact with the lip.
  • the inside of the smoking segment 4 includes granular smoke-emitting substances.
  • the sealing piece 1 is a breathable sealing film. At least two rows of vent holes are arranged on the empty tube 2 and the aesthetic paper layer 3 axially corresponding to the hollow cooling section 7 to connect a hollow cavity of the hollow cooling section 7 with the outside.
  • the limiting segment 5 is a perforated cylinder or a perforated disc, the hollow cooling segment 7 is a cavity and the filter segment 8 is a polymer fiber tow segment.
  • a heated cigarette which differs from Embodiment 1 only in that the empty tube 2 is not wrapped with the aesthetic paper layer 3.
  • a batch of 200 double-layer heated cigarettes of Embodiment 1 and a batch of 200 heated cigarettes of Comparative Example 1 were prepared, respectively, and dispensed into cigarette cases and shipped to the preparation site. The cigarette cases were then opened and checked, The fall-off rate of the sealing pieces 1 of the double-layer heating cigarettes in Embodiment 1 is 0, and the fall-off rate of the sealing pieces 1 of the heating cigarettes in Comparative Example 1 is 5%.
  • the technical solution of the present invention makes it possible to significantly reduce the fall-off rate rate of the sealing piece 1.
