Definitions

  • the following disclosure relates to devices for generating an aerosol which is inhaled by a user, such as electronic cigarettes.
  • the disclosure relates to aerosol generation devices where the aerosol is generated by heating an aerosol substrate.
  • Aerosol generation devices consume an aerosol substrate in order to generate an aerosol.
  • a user of the device must replace the aerosol substrate periodically in order to generate more of the aerosol.
  • aerosol generation devices often include a mouthpiece through which the user may inhale the generated aerosol.
  • the mouthpiece must be kept clean to maintain hygiene. It is desirable to make it easy for the user to use the device. The simplest way to achieve this is to make the entire device disposable, such that the user replaces the aerosol substrate and provides a clean mouthpiece, by replacing the entire device.
  • the consumable aerosol substrate can be packaged in a container configured to interface with the device, such that the user can replace the container without having to directly handle the aerosol substrate.
  • the mouthpiece may be provided as a part of the container.
  • the present disclosure provides an aerosol generation device comprising: a power supply module comprising an electrical power supply; a substrate module comprising a container for an aerosol substrate; and a heater module configured to detachably engage with the power supply module, the heater module comprising: a mouthpiece; a heating element configured to receive power from the electrical power supply and heat the aerosol substrate to generate an aerosol; and a receiving means configured to detachably engage with the substrate module and bring the heating element and the aerosol substrate together for generating the aerosol, wherein: the container of the substrate module is sealed prior to engaging with the heater module, and the heater module is configured to break the sealing of the container upon or after engaging with the substrate module, the heater module is adapted to partly enclose the substrate module when engaged therewith, and the power supply module is adapted to partly enclose the heater module when engaged therewith.
  • the power supply module, substrate module and heater module can be individually replaced only as often as necessary. Furthermore, each module can be made of entirely different materials and manufactured separately before being assembled into the device. The assembly of modules to form the complete aerosol generation device can be performed by the end user and/or performed as an additional industrial manufacturing stage.
  • the aerosol substrate is a liquid or gel.
  • Liquid or gel substrates are particularly difficult for a user to handle directly, and the benefits of providing a container for the substrate are greater than for a solid substrate.
  • the substrate module comprises a fluid transfer element configured to transfer liquid from the container to the heating element.
  • a fluid transfer element configured to operate with the heater module makes handling a liquid substrate easier and more reliable to increase aerosol generation and decrease wastage of the substrate.
  • the receiving means comprises a closure component arranged to open for receiving the substrate module and to close for aerosol generation.
  • a closure component By providing a closure component, the substrate module can be entirely contained within the receiving means during aerosol generation, meaning that the conditions for aerosol generation can be more precisely controlled, and the quality of generated aerosol can be improved.
  • the receiving means is a clam-shell container or a container comprising a housing closed by a closing door.
  • a clam-shell container or housing-and-door container configuration each provide a specific closure component that is simple to operate and robust.
  • the sealing of the container comprises a first layer that is not soluble in the aerosol substrate and a second layer that is soluble in the aerosol substrate.
  • the soluble layer comprises a polysaccharide, starch or protein-based material or biodegradable polyvinylalcohol (PVA) film.
  • PVA polyvinylalcohol
  • the sealing of the container comprises a foil seal layer comprising a moisture barrier. This has the effect of improving hygiene and reducing moisture exchange between the substrate module and an environment.
  • the container and/or sealing of the container comprises a polymer film comprising a gas barrier and/or moisture barrier layer or coating and at least one support layer.
  • the gas and/or moisture barrier layer is EVOH, PVOH, SiOx, or natural wax or combinations thereof.
  • the support layer comprises: paper, polylactic acid (PLA), poly(glycolic acid) (PGA), bio-PET, PBAT, polymer(s) of cellulose-derived or starch-derived biodegradable polymers (BPs), chitosan or microbially synthesized polyesters.
  • PLA polylactic acid
  • PGA poly(glycolic acid)
  • PBAT poly(s) of cellulose-derived or starch-derived biodegradable polymers
  • BPs cellulose-derived or starch-derived biodegradable polymers
  • chitosan or microbially synthesized polyesters chitosan or microbially synthesized polyesters.
  • the receiving means comprises a piercing element configured to pierce or cut the sealing of the container.
  • a piercing element configured to pierce or cut the sealing of the container.
  • the sealing of the container is configured to break upon melting, burning or decomposing upon heating by the heating element and the heating element is configured to melt, burn or decompose the sealing of the container.
  • the heater module is configured to open the sealing of the container upon commencing aerosol generation.
  • This has the advantage of not opening the substrate module until the user wishes to perform aerosol generation, allowing the user to store a substrate module in the device without any risk of a leak and, in the general case where multiple different aerosol substrates can be used in the device, allowing the user to change their mind about which aerosol substrate should be used by swapping the substrate module even after the substrate module has engaged with the receiving means.
  • the substrate module is biodegradable or compostable (according to EN1342 Standard). This reduces the environmental impact of the device, particularly because the part of the device that is expected to be replaced most frequently has reduced environmental impact.
  • the container and/or the sealing of the container comprise a polysaccharide, starch or protein-based material, paper, polylactic acid (PLA), poly(glycolic acid) (PGA), bio-PET, PBAT, polymer(s) of cellulose-derived or starch-derived biodegradable polymers (BPs), chitosan or microbially synthesized polyesters.
  • PLA polylactic acid
  • PGA poly(glycolic acid)
  • PBAT polymer(s) of cellulose-derived or starch-derived biodegradable polymers
  • BPs cellulose-derived or starch-derived biodegradable polymers

  • the heating element is detachable from the heater module. This improves the adaptability of the device such that parts can be replaced only as frequently as necessary. For example, some users may wish to improve hygiene by replacing the mouthpiece with the heater module more often than they replace the heating element.
  • the mouthpiece can be cleaned or covered to remain hygienic for longer, and the heating element may have a shorter lifetime than the rest of the heater module. Additionally or alternatively, the heating element may be detached for the purpose of cleaning to extend its lifetime.
  • the electrical power supply is detachable from the power supply module.
  • the device may be used continuously by swapping the electrical power supply.

  • the aerosol substrate 121 can be drawn out of the substrate module 12 and the aerosol can be generated.
  • the sixth example of a heater module 13 may be configured to only move the moveable fluid transfer element 1371 into the extended position when the user is ready for aerosol generation. This means that the sealing 122 is not broken prior to commencing aerosol generation, and the risk of a leak is reduced when the substrate module 12 is stored assembled in the device 1.
  • the aerosol generation device 1 may be distributed in various forms.
  • the aerosol generation device 1 may be distributed as a fully formed device having a power supply module 11 , a substrate module 12 and a heater module 13.
  • the device 1 may also be distributed as a kit comprising a power supply module 11 , one or more substrate modules 12 and one or more heater modules 13.
  • the substrate module 12 will be replaced more frequently than the heater module 13 or the power supply module 11 , and the substrate module 12 may be distributed as a package of one or more substrate modules 12.
  • Fig. 9 is a schematic block diagram of a package 2 of replaceable modules for an aerosol generation device.
  • a plurality of substrate modules 12 may be distributed in a form where they are attached to a cardboard support 21.
  • the cardboard support 21 may, for example, be an open cardboard sheet, a pair of open cardboard sheets between which the substrate modules are arranged, or a cardboard enclosure surrounding the substrate modules 12.
  • Each substrate module 12 may be attached to the cardboard support 21 using a dot of glue.
  • Using a cardboard support has the advantage that, if the substrate modules 12 are biodegradable as described above, then the whole package is biodegradable.
  • the substrate module 12 and heater module 13 can be distributed accordingly in a package with multiple substrate modules 12 per heater module 13.
  • the number of substrate modules 12 per heater module 13 may typically be in the range of six to twenty.
  • Each of the substrate modules 12 and the heater module 13 may be wrapped, for example in a foil pack such as flow wrap, for hygiene and to protect the module before use.
  • the heater module 13 is recommended to be replaced after every six substrate modules 12 have been used, and the package 2 comprises one heater module 13 and six substrate modules 12 mounted on or enclosed in a cardboard support 21.
  • the heating element 132 may be detachable from the heater module 13.
  • the heating element 132 may be detachable from the heater module 13.
  • the heater module 13 comprises a cradle 1321 adapted to receive the heating element 132 via the receiving means 133. More specifically, when the closure component 1331 is in an open position, and no portion 2 of aerosol generating substrate is present, the receiving means 133 may provide access to the cradle 1321 for inserting the heating element 132.
  • the heating element 132 may for example be a disposable resistive element adapted to engage with electrical contacts in the cradle 1321 , and the cradle may consist of supports for two opposite ends of the heating element, each support having an electrical contact.
