Definitions

  • the present invention concerns a cartridge for storing a vaporizable material for an aerosol generating device.
  • aerosol generating devices comprise a storage portion for storing a vaporizable material, also known as aerosol forming precursor, which can comprise for example a liquid or a solid.
  • a heating system is formed of one or more electrically activated resistive elements arranged to heat said precursor to generate the aerosol.
  • the aerosol is released into a flow path extending between an inlet and outlet of the device.
  • the outlet may be arranged in a mouthpiece, through which a user inhales for delivery of the aerosol.
  • the aerosol generating devices comprise generally a battery able to power the heating system.
  • the powering may be controlled by a control module connecting the heating system to the battery via an electric circuit.
  • the precursor is stored in a removable cartridge.
  • the cartridge can be easily removed and replaced.
  • One of the aims of the present invention is to propose a cartridge making it possible to be recycled after being used. This can notably reduce the carbon dioxide production due to cartridge manufacturing.
  • the invention relates to a cartridge for storing a vaporizable material for an aerosol generating device, the cartridge comprises a cartridge body defining an internal surface; the cartridge further comprising a coating covering the internal surface of the cartridge body and being extractable from the cartridge body before recycling the cartridge body.
  • the internal surface of the cartridge is not directly in contact with the vaporizable material. Hence, after using the cartridge, and extracting the coating covering the internal surface of the cartridge body, said cartridge body can be recycled in a simple manner.
  • the coating is extractable from the cartridge body with at least one internal element of the cartridge body having been in contact with the vaporizable material.
  • the coating covers at least one internal element of the cartridge body different from the internal surface.
  • said internal element is chosen in the group comprising:
  • the coating is extractable using a removal process comprising at least one operation chosen in the group comprising:
  • the coating is extractable using a simple removal process.
  • the mentioned techniques are easy to implement in a manufacturing context.
  • the coating comprises a foil or film.
  • the coating can be particularly thin since the foil, or film, ensures a relatively small thickness.
  • the coating does not substantially reduce the storing volume of the cartridge.
  • the coating is impermeable or water repellent.
  • the coating comprises a peelable tie or seal layer.
  • the vaporizable material is liquid.
  • the internal surface delimits a storage portion of the cartridge adapted to store the vaporizable material.
  • the most important surface area intended to be normally in contact with the vaporizable material is isolated by the coating from it.
  • the cartridge body is made of polypropylene or PET.
  • aerosol generating device or “ device” may include a vaping device to deliver an aerosol to a user, including an aerosol for vaping, by means of aerosol generating unit (e.g. an aerosol generating element which generates vapor which condenses into an aerosol before delivery to an outlet of the device at, for example, a mouthpiece, for inhalation by a user).
  • the device may be portable.
  • “Portable” may refer to the device being for use when held by a user.
  • the device may be adapted to generate a variable amount of aerosol, e.g. by activating a heating system for a variable amount of time (as opposed to a metered dose of aerosol), which can be controlled by a trigger.
  • the trigger may be user activated, such as a vaping button and/or inhalation sensor.
  • the inhalation sensor may be sensitive to the strength of inhalation as well as the duration of inhalation to enable a variable amount of vapor to be provided (so as to mimic the effect of smoking a conventional combustible smoking article such as a cigarette, cigar or pipe, etc.).
  • the device may include a temperature regulation control to drive the temperature of the heater and/or the heated aerosol generating substance (aerosol pre-cursor) to a specified target temperature and thereafter to maintain the temperature at the target temperature that enables efficient generation of aerosol.
  • aerosol may include a suspension of precursor as one or more of: solid particles; liquid droplets; gas. Said suspension may be in a gas including air. Aerosol herein may generally refer to/include a vapor. Aerosol may include one or more components of the precursor.
  • vaporizable material or " aerosol-forming precursor" may refer to one or more of a: liquid; solid; gel; mousse; foam or other substances.
  • the vaporizable material may be processable by the heating system of the device to form an aerosol as defined herein.
  • the vaporizable material may comprise one or more of: nicotine; caffeine or other active components.
  • the active component may be carried with a carrier, which may be a liquid.
  • the carrier may include propylene glycol or glycerin.
  • a flavoring may also be present. The flavoring may include Ethylvanillin (vanilla), menthol, Isoamyl acetate (banana oil) or similar.
  • a solid aerosol forming substance may be in the form of a rod, which contains processed tobacco material, a crimped sheet or oriented strips or shreds of reconstituted tobacco (RTB).
