Definitions

  • the present invention is directed to electronic cigarettes; more specifically, the present invention is directed to a consumable container for filling e-liquid into a heating cavity of an aerosol generation device, the aerosol generation device, a refillable aerosol generation system thereof and a method for using the refillable aerosol generation system.
  • An aerosol generation device or e-cigarette, is now a mainstream product to simulate a traditional tobacco cigarette.
  • the operation method of the aerosol generation device is to contain an aerosol generation carrier inside and to heat it.
  • One type of the e-cigarette evaporates an e-liquid to form vapor which the user can inhale, so using such an e-cigarette is usually called “vaping”.
  • E-liquid is well-known as a type of mixture solution used in vapor systems.
  • E-liquid usually contains nicotine, and may also contain propylene glycol, glycerin, flavorings, additives, and/or other kinds of vaping containments.
  • There are different subtypes of this kind of e-cigarette such as a closed tank system and an open tank system.
  • the open tank system comprises a fixed heating chamber in the device, which allows users to refill the device with any e-liquid without the need of attaching another element thereon, giving them maximum scope for personalization and individual control.
  • the refilling of the open tank system can be achieved by using specific containers.
  • WO 2013/060827 At relates to kits for supplying a cartridge of an open-tank inhaler article with liquid tobacco extract. More specifically, spray or bottle types of kits are disclosed to deliver the liquid tobacco extract to the cartridge.
  • a mixture of cut tobacco and propylene glycol is provided in the bottle through a spray nozzle.
  • the user squeezes the deformable bottle, and drops of tobacco extract are absorbed onto the cartridge.
