Definitions

  • the present disclosure relates generally to a cartridge for a vapour generating system configured to heat a vapour generating liquid to generate a vapour which cools and condenses to form an aerosol for inhalation by a user of the system.
  • Embodiments of the present disclosure relate in particular to a method of filling a cartridge for a vapour generating system with a vapour generating liquid.
  • vapour generating system refers to a handheld electronic device that is intended to simulate the feeling or experience of smoking tobacco in a traditional cigarette.
  • Electronic cigarettes work by heating a vapour generating liquid to generate a vapour that cools and condenses to form an aerosol which is then inhaled by the user. Accordingly, using e-cigarettes is also sometimes referred to as “vaping”.
  • the vapour generating liquid usually comprises nicotine, propylene glycol, glycerine, and flavourings.
  • Typical e-cigarette vaporizing units i.e. systems or sub-systems for vaporizing the vapour generating liquid, utilize a cotton wick and heating element to produce vapour from liquid stored in a capsule or tank.
  • a heating element When a user operates the e-cigarette, liquid that has soaked into the wick is heated by the heating element, producing a vapour which cools and condenses to form an aerosol which may then be inhaled.
  • cartridges are often used. These cartridges are often configured as “cartomizers”, which means an integrated component formed from a liquid store (reservoir), a liquid transfer element (e.g. a wick) and a heater.
  • Electrical connectors may also be provided to establish an electrical connection between the heating element and a power source.
  • Such cartridges may be disposable, i.e. not intended to be capable of reuse after the supply of liquid in the reservoir has been exhausted. Particularly in the case of disposable cartridges, but also in the case of refillable cartridges, it is desirable to reduce the number and complexity of the cartridge components, thereby reducing waste and making the manufacturing process simpler and cheaper.

  • the vapour generating liquid may comprise polyhydric alcohols and mixtures thereof such as glycerine or propylene glycol.
  • the vapour generating liquid may contain nicotine and may, therefore, be designated a nicotine-containing liquid.
  • the vapour generating liquid may contain one or more additives, such as a flavouring.
  • 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
