Definitions

  • the present disclosure relates generally to aerosol generating articles, and more particularly to an aerosol generating article for use with an aerosol generating device for heating the aerosol generating article to generate an aerosol for inhalation by a user.
  • Embodiments of the present disclosure also relate to a method of manufacturing an aerosol generating article.
  • the present disclosure is particularly applicable to aerosol generating articles for use with a portable (hand-held) aerosol generating device.
  • 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.
  • a commonly available reduced-risk or modified-risk device is the heated substrate aerosol generating device, or so-called heat-not-bum device.
  • Devices of this type generate an aerosol or vapour by heating an aerosol generating substrate to a temperature typically in the range 150°C to 300°C. Heating the aerosol generating substrate to a temperature within this range, without burning or combusting the aerosol generating substrate, generates a vapour which typically cools and condenses to form an aerosol for inhalation by a user of the device.

  • a method of manufacturing an aerosol generating article for use with an aerosol generating device comprising: providing a plurality of aerosol generating strips extending in a first direction and arranging the plurality of aerosol generating strips intermittently in a second direction perpendicular to the first direction; providing a plurality of elongate support elements extending in the first direction along the plurality of aerosol generating strips and arranging the plurality of elongate support elements alternately in the second direction with the plurality of aerosol generating strips; and wrapping the plurality of aerosol generating strips and the plurality of elongate support elements with a wrapping member to form a substantially planar aerosol generating article.
  • 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.
  • vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapour can be condensed to a liquid by increasing its pressure without reducing the temperature
  • aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas.
  • the elongate support elements help to maintain the structural rigidity and cross- sectional shape of the aerosol generating article, in particular by resisting or preventing deformation of the aerosol generating strips.
  • the elongate support elements By providing a plurality of elongate support elements extending in the first direction, the risk of deformation of the aerosol generating article during processing and/or storage and/or handling of the aerosol generating article, for example as a result of crushing or compression of the aerosol generating article, is minimised.
  • the risk of an airflow route for example provided by an airflow channel, becoming obstructed during processing and/or storage and/or handling of the aerosol generating article is also minimised.
  • the vapour and/or aerosol generated during use of the aerosol generating article in an aerosol generating device flows internally within the article, along an airflow route such as an airflow channel, before it is inhaled by a user. This may help to ensure that the greatest possible quantity of vapour and/or aerosol is delivered to the user, and that the delivered vapour and/or aerosol has optimal characteristics.
  • the elongate support elements may comprise a material which has a greater strength or rigidity or stiffness than the aerosol generating strips. Deformation of the aerosol generating strips is thereby resisted or prevented by the elongate support elements.
  • the elongate support elements may comprise any one of paper, moulded pulp, metal, a woven fabric (e.g., cloth), a non-woven fabric, or flame retardant wood. Each of these materials may provide a number of advantages.
  • paper provides advantages including light weight, low cost, processability, temperature resistance, and low risk of generating unwanted volatile components (i.e., controllable generation); moulded pulp provides advantages including light weight, processability, temperature resistance, and strength (compared to normal paper); metal provides advantages including temperature resistance, high thermal conductance, and low risk of generating unwanted volatile components (i.e., controllable generation); a woven fabric or a non- woven fabric provides advantages including low cost, temperature resistance, and low risk of generating unwanted volatile components (i.e., controllable generation); flame retardant wood provides advantages including processability, temperature resistance and strength (compared to normal paper).
  • the aerosol generating article may include a distal end, a mouth end (or mouth-end portion) and a longitudinal axis which may extend between the mouth end and the distal end.
  • the mouth end (or mouth-end portion) is located at an opposite end of the aerosol generating article to the distal end. More particularly, the mouth end (or mouth end portion) 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, i.e., when, in use, a user inhales through the mouth end (or mouth-end portion).
  • the mouth end (or mouth-end portion) constitutes a downstream portion of the aerosol generating article.
  • the first direction may be substantially parallel to the longitudinal axis.
  • the support members may extend in a direction substantially parallel to the longitudinal axis, between the distal end and the mouth end. Air flows through the aerosol generating article, from the distal end to the mouth end, during use of the aerosol generating article thereby ensuring that a maximum amount of volatile components are released into the air from the heated aerosol generating strips. This in turn ensures that the greatest possible quantity of vapour and/or aerosol is generated and delivered to the user during use of the aerosol generating article.
  • the elongate support elements may be longer than the aerosol generating strips in the first direction.
  • the elongate support elements may extend beyond an end of the aerosol generating strips to form a mouth-end portion (or mouth end) of the aerosol generating article. This may help to improve the rigidity and structural integrity of the aerosol generating article at the mouth-end portion (or mouth end), where the aerosol generating article is engaged by a user’s lips.
  • the wrapping member may form a pair of major surfaces which may have a substantially flat shape, at least one of the major surfaces may be spaced from the aerosol generating strips to form a gap between the major surface and the aerosol generating strips, and the gap may extend in the first direction along the aerosol generating strips to form an airflow channel.
  • the airflow channel provides a route for aerosol and/or vapour to flow internally within the aerosol generating article. The formation of condensed matter on the internal surfaces of the aerosol generating device is thereby substantially eliminated, or at least minimised.
  • One of the major surfaces of the wrapping member may contact the plurality of elongate support elements to space it from the aerosol generating strips and thereby form said gap.
  • the gap, and hence the airflow channel, is, thus, readily formed at the time of manufacture of the aerosol generating article due to the contact between the major surface of the wrapping member and the elongate support elements.
  • One of the major surfaces of the wrapping member may contact the plurality of aerosol generating strips and the plurality of elongate support elements. This may help to facilitate correct positioning of the wrapping member with respect to the aerosol generating strips and the support elements.

  • the wrapping member may comprise a pair of rectangular sheets which may be attached, respectively, to the pair of main surfaces.
  • the aerosol generating article may have a pleasing aesthetic appearance due to the flat rectangular shape of the aerosol generating substrate formed by the plurality of aerosol generating strips.
  • the aerosol generating strips forming the aerosol generating substrate may be readily covered by the wrapping member, thereby ensuring that a user does not directly touch the aerosol generating strips during handling of the aerosol generating article.
  • the flat rectangular shape may also facilitate packaging and storage of multiple aerosol generating articles.
  • the aerosol generating article may comprise a support member which may form a mouth-end portion of the article.
  • the support member may have a tubular form, e.g., a rectangular tubular form, to receive a downstream end of the aerosol generating strips and the elongate support elements.
  • the support member may be self-supporting and may, for example, comprise cardboard or a plastics material.
  • the support member may advantageously deliver vapour and/or aerosol generated during use of the article directly to a user’s mouth.
  • the support member may allow heated vapour generated during use of the aerosol generating article to cool and condense to form an aerosol with optimal characteristics for inhalation by a user.
  • the wrapping member may comprise a material which is substantially non-electrically conductive and non-magnetically permeable and may, for example, comprise a paper wrapper.
  • a paper wrapper may facilitate manufacture and handing of the aerosol generating article and may enhance aerosol generation.
  • the wrapping member may have a porous inner surface which may face towards the aerosol generating substrate, and more particularly towards the aerosol generating strips, for absorbing condensation.
  • the porous inner surface may help to ensure that the formation of condensed matter on the internal surfaces of the aerosol generating device is substantially eliminated, or at least minimised.
  • the wrapping member may have an anti-stick outer surface which may face away from the aerosol generating substrate, and more particularly away from the aerosol generating strips.
  • the wrapping member may comprise an anti-stick coating on the outer surface.
  • the anti-stick outer surface may help to ensure that the wrapping member does not stick to surfaces of the aerosol generating device when it has been heated. Together, the porous inner surface and the anti-stick outer surface may help to reduce residue build-up within the aerosol generating device, thus reducing the number of cleaning and maintenance operations that a user of the device may have to perform.
  • the aerosol generating substrate and more particularly the aerosol generating strips, may comprise a non-liquid aerosol generating material, for example any type of solid or semi-solid material.
