Definitions

  • reduced-risk or modified-risk devices also known as aerosol generating devices or vapour generating devices
  • vapour generating devices Various devices and systems are available that heat or warm aerosol generating substances to generate an aerosol for inhalation by a user.
  • the aerosol generating article is for use with an aerosol generating device for heating the aerosol generating substrate, without burning the aerosol generating substrate, to volatise at least one component of the aerosol generating substrate and thereby generate a heated vapour which cools and condenses to form an aerosol for inhalation by a user of the aerosol generating device.
  • the aerosol generating device is a hand-held, portable, device.
  • a method of manufacturing an aerosol generating article for use with an aerosol generating device comprising:
  • the aerosol generating article may include a distal end, a mouth end and a longitudinal axis which may extend between the mouth end and the distal end.
  • the mouth end is located at an opposite end of the aerosol generating article to the distal end. More particularly, the mouth end is located downstream of the distal end with respect to an airflow direction through the aerosol generating article, e.g., during use of the aerosol generating article in an aerosol generating device.
  • the at least one channel-forming strip may extend in a first direction which may be substantially parallel to the longitudinal axis. Thus, the airflow channel formed by melting the meltable material also extends in the first direction.
  • a single channel-forming strip may be positioned internally within the aerosol generating substrate, for example in a substantially central position within the cross-section of the aerosol generating substrate.
  • a plurality of channel-forming strips may be positioned internally within the aerosol generating substrate, and the channel-forming strips may be arranged side by side, e.g., in a second direction perpendicular to the first direction (longitudinal direction).
  • the aerosol generating substrate may comprise a plurality of aerosol generating strips which may extend in a first direction, e.g., parallel to the longitudinal axis, and may be arranged intermittently in a second direction which may be substantially perpendicular to the first direction.
  • the aerosol generating article may comprise a plurality of said channel-forming strips and one of said channel-forming strips may be positioned between each pair of intermittently arranged aerosol generating strips. With this arrangement, the channel-forming strips can be easily positioned in the aerosol generating substrate during manufacture of the aerosol generating article, for example by spacing apart the aerosol generating strips in the second direction to form spaces for positioning the channel-forming strips.
  • the aerosol generating article can also be manufactured efficiently and mass produced with relative ease.
  • the aerosol generating substrate may comprise an aerosol generating material for generating an aerosol when heated by an aerosol generating device, and more particularly when heated by a heating element of an aerosol generating device.
  • the aerosol generating substrate may comprise a non-liquid aerosol generating material, for example any type of solid or semi-solid material.
  • Example types of aerosol generating solids include powder, granules, pellets, shreds, strands, particles, gel, strips, loose leaves, cut leaves, cut filler, porous material, foam material or sheets.
  • the aerosol generating substrate may comprise plant derived material and in particular, may comprise a tobacco. It may advantageously comprise reconstituted tobacco, for example including tobacco and any one or more of cellulose fibres, tobacco stalk fibres and inorganic fillers such as CaCO3.
  • the aerosol generating device with which the aerosol generating articles are intended for use may be referred to as a “heated tobacco device”, a “heat-not-burn tobacco device”, a “device for vaporising tobacco products”, and the like, with this being interpreted as a device suitable for achieving these effects.
  • the features disclosed herein are equally applicable to devices which are designed to vaporise any aerosol generating substrate.
  • the heating element of the aerosol generating device may comprise a resistive heating element.
  • the heating element may alternatively comprise an inductively heatable susceptor, and the aerosol generating device may further comprise an electromagnetic field generator, e.g., comprising an induction coil, for inductively heating the susceptor.
  • the aerosol generating substrate may release volatile compounds.
  • the volatile compounds may include nicotine or flavour compounds such as tobacco flavouring.
  • FIG. 1 is a diagrammatic longitudinal cross-sectional view of a first example of an aerosol generating article having a plurality of channel-forming strips:
  • FIG. 3 is a diagrammatic cross-sectional view similar to FIG. 2 , after the channel-forming strips have melted:
  • FIG. 4 is a diagrammatic cross-sectional view similar to FIG. 2 of a second example of an aerosol generating article having a plurality of channel-forming strips:
  • FIG. 9 is a diagrammatic cross-sectional view of an aerosol generating system comprising an aerosol generating device and an aerosol generating article according to the present disclosure.
  • FIGS. 1 to 3 there is shown a first example of an aerosol generating article 1 for use with an electrically-operated aerosol generating device 102 , an example of which will be described later in this specification with reference to FIG. 9 .
  • the aerosol generating article 1 is substantially planar and has a distal end 10 and a mouth end 12 (or proximal end) at the opposite end of the aerosol generating article 1 .
  • the mouth end 12 is downstream of the distal end 10 with respect to an airflow direction through the aerosol generating article 1 as represented in FIG. 1 by the three arrows.
  • airflow through the aerosol generating article 1 shown in FIG. 1 is initially substantially prevented by channel-forming strips 40 , as will be described in more detail below.
  • a longitudinal axis extends between the distal end 10 and the mouth end 12 to define a longitudinal direction of the aerosol generating article 1 .
  • the aerosol generating article 1 comprises a substantially planar aerosol generating substrate 14 .
  • the aerosol generating substrate 14 comprises a bulk or mass of aerosol generating material and has a flat rectangular shape with a pair of oppositely disposed main surfaces 14 a , 14 b .
  • the aerosol generating article 1 is a consumable, or disposable, article in which the aerosol generating substrate 14 may comprise tobacco or a tobacco material.
  • grooves 18 are shown in the example of FIGS. 1 to 3 , but it will be understood that any suitable number of grooves 18 can be provided, for example depending on the desired resistance-to-draw of the aerosol generating article 1 . It should also be noted that the grooves 18 may have any suitable cross-sectional shape including, but not limited to, square as illustrated in FIGS. 2 and 3 , rectangular, trapezoidal, or semi-circular.
  • the aerosol generating substrate 14 is heated without burning to release one or more volatile components.
  • the volatile components are entrained in the air flowing through the grooves 18 thereby forming a vapour.
  • the vapour cools and condenses as it flows through the grooves 18 to form an aerosol which is inhaled by a user through the mouthpiece 118 of the aerosol generating device 102 .
  • the meltable material does not itself comprise any active agents, e.g., nicotine, aerosol former, flavourants, or the like, that are capable of releasing volatile components into the generated aerosol when the meltable material is heated by the heater 104 .
