Definitions

  • the present disclosure relates to a cartridge for an aerosol-generating device and an aerosol generating device accommodating such a cartridge. It further relates to a method of replacing said cartridge in the aerosol-generating device and a method of re-filling the cartridge.
  • Aerosol-generating devices otherwise known as aerosol-generating devices, vapes, or Heat- not-Burn devices, are becoming a popular alternative to smoking traditional tobacco cigarettes.
  • Tobacco vapour (T-vapour) devices are a type of aerosol-generating device which heat tobacco at a lower temperature compared to traditional cigarettes. These devices are often referred to as heat not burn devices.
  • the vaporisable material is usually provided in the form of sticks of aerosol generating material, usually a tobacco-containing material. These sticks are designed to be heated and not combusted as standard cigarettes are. A part of the stick comprising the aerosol-generating material can be inserted into a heating chamber of the aerosol-generating device which includes a heater for heating the inserted part of the stick. After consumption the stick can be removed and disposed of until a next consumption of a fresh stick by a user.
  • a further issue is that the tobacco stick is typically held together by a thin binding outer layer.
  • the tobacco material may become dislodged from the stick and become stuck within the heating chamber of the device. This can lead to the performance of the device being affected, as the dislodged tobacco may affect the efficiency of heat transfer from the device to the tobacco. This places the burden on the user to ensure that the device is regularly cleaned.
  • What is required is a way of providing tobacco material for a T-vapour device that reduces the amount of heat radiated to the outer casing of the device, whilst also preventing the leakage of tobacco material, or any aerosol-generating material or substrate in general, into the device.
  • a cartridge for use in an aerosol-generating device comprising: a tubular outer body; an internal compartment for accommodating a solid or semi-solid aerosol-generating substrate; first and second air- permeable end caps configured to retain the aerosol-generating substrate and to allow an airflow in the internal compartment; and at least one heating member configured to extend within the internal compartment and to heat the aerosol-generating substrate contained therein, wherein the heating member is fixedly connected to one of the first and second end cap or to the tubular outer body.
  • the heating member is rod-shaped.
  • the heating member has a length, in the direction in which it extends in the internal compartment, longer than its width.
  • This type of heater may commonly be known as a rod, needle or blade heater.
  • the heating member is configured to extend within the internal compartment and to be in direct contact, and thereby heat, the aerosol-generating substrate contained therein.
  • the heating member is in direct contact with the aerosol-generating substrate. This ensures that heat is supplied at the location where it is needed, through directly heating the aerosol-generating substrate, thereby minimising heat transfer to the external cavity of the vapour generating device.
  • the cartridge is provided with its own heating member rather than relying on a heating member external to the cartridge in the aerosol-generating device.
  • the first and second end caps act to seal the aerosol-generating substrate within the cartridge along with the heating member. This ensures that the aerosol-generating substrate is fully contained within the cartridge when inserted for use into the aerosol-generating device. This avoids the leakage of aerosol-generating substrate from the cartridge into the aerosol-generating device which may affect its performance, and ultimately require cleaning.
  • the heating member may be further connected to an electrical connector arranged at an outer surface of said one of the first and second end caps or to the tubular body.
  • the electrical connector is configured to provide an electrical connection between the cartridge and the aerosol-generating device.
  • the electrical connector may be configured to provide an electrical connection between the heating member and an electrical power source. This enables the heating member to receive electrical power from the aerosol-generating device to generate heating.
  • the electrical connector may comprise at least a first terminal and a second terminal electrically insulated from one another. The first terminal and the second terminal may be configured to contact a corresponding terminal on the aerosol-generating device.
  • the first terminal may be a positive terminal and the second terminal may be a negative terminal.
  • the electrical connector is integral with the heating member.
  • the heating member may form the electrical connector. This enables the electrical connection to be applied directly to the heating member.
  • the electrical connector may be separate components to the heating member.
  • the heating member may comprise an electrical resistor that can be electrically heated when electricity is supplied through the electrical connector.
  • the electrical resistor can provide heat through Ohmic heating. In this way, the heat is generated by the heating member within the internal compartment. This means that the heat is applied directly to the aerosol-generating substrate, and minimises the heat that is radiated to the outer portions of the aerosol-generating device.
  • the heating member may comprise an inductively energizable susceptor material.
  • a susceptor material heating of the heating member can be provided through the application of electromagnetic energy. In this way, direct contact between the inductor and the heating member is not required. This means that the heating member does not require physical connectors to transfer energy from the aerosol-generating device in order to cause it to heat.
  • the amount of heat that is radiated to the outer casing of the aerosol-generating device can be kept low.
  • the tubular outer body may comprise a thermal insulator. Having a heat resistant tubular outer body can reduce the heat that is radiated out from the cartridge to the aerosol-generating device when the cartridge is in use. This is advantageous as it prevents the aerosol generating device becoming too hot for the user to hold. It also increases the efficiency of the device. This is because the heat is not lost to the surroundings as the insulator ensures that the heat remains in the cartridge.
  • the thermal insulator may be a glass. Alternatively, the thermal insulator may be a plastic or ceramic material.
  • the heating member extends along a substantial length of the internal compartment between the first and second air-permeable end caps. In some arrangements it may extend along more than a third of the length of the internal compartment between the first and second air-permeable end caps. In other arrangements, the heating member may extend along more than half of the length of the internal compartment between the first and second air permeable end caps. This enables the heating member to be in contact with a large proportion of the aerosol-generating substrate along the length of the internal compartment. This can ensure that the heat is distributed to the maximum amount of the aerosol-generating substrate, and helps to provide uniform heating to the entire aerosol-generating substrate. In other arrangements, the heating member may extend along the entire length of the internal compartment between the first and second caps. Alternatively, it may extend only down a portion of the length of the internal compartment.
  • the cartridge may comprise the aerosol-generating substrate contained within the internal compartment.
  • the aerosol-generating substrate may comprise tobacco.
  • the aerosol generating substrate may be solid or semi-solid.
  • the aerosol-generating substrate is preferably aerated tobacco mousse or equivalent foamy tobacco substrate. This may include those described in WO 2020/002607 A1 which is incorporated herein by reference. For instance, they may be formed by mixing of tobacco with aerosol formers (PG, VG, 1.3 PDO). It may also be formed by mixing the tobacco and aerosol formers with flavours and/or binders. Other tobacco materials for use in a heat-not-burn system may be used. For instance those formed from reconstituted tobacco blend material mixed with aerosol formers.
  • the either of the end caps are removable to allow access to the internal compartment for removal and replacement of the aerosol-generating substrate. This enables the cartridge to be recycled for use multiple times. Having a refillable cartridge provides environmental advantages as the cartridge can be used multiple times. This also enables the end caps to be replaced without having to dispose of the rest of the cartridge. This is beneficial as the end caps, and/or the heating member, may become damaged requiring replacement.
  • the first or second end cap may comprise a thread and the tubular outer body may comprise a corresponding complementary thread for attaching the first or second end cap to the outer body. Having a threaded connection may ensure that the cap is securely fastened to the tubular outer body. This avoids the cap from accidently becoming detached from the tubular outer body when in use which may cause the aerosol-generating substrate to spill into the aerosol-generating device.
  • a different attachment between the end caps and the tubular outer body may be used. For instance, an interference or press fit may be used, where the end cap has a similar circumference as the tubular outer body.
  • only one of the end caps may be removable. In other arrangements both end caps may be removable.
  • first and second end caps may be fixed in place so that access to the internal compartment is prevented. This may prevent a user from removing the end caps and exposing the heating member. This may be desirable for health and safety reasons preventing the user handling the heating member when hot. In this way, the device is fully disposable. This may be when the aerosol-generating substrate has run out, and/or when the heating member is no longer functioning correctly.
  • an aerosol-generating device comprising: a housing; a cartridge of the aspect described above, wherein the cartridge is removably receivable in a compartment of the housing; and an airflow channel arranged in the housing to allow an airflow from outside the housing into the internal compartment of the cartridge through at least one of the first and second end caps; a power source, wherein the power source is configured to supply energy to the heating member and thereby generate an aerosol by heating the aerosol-generating substrate,; and a mouthpiece through which a user can inhale the generated aerosol, wherein the mouthpiece is fluidly connected to the internal compartment of the cartridge and the airflow channel.
  • the energy supplied by the power source is electrical energy, which can be supplied to the heating member for it to heat the aerosol-generating substrate in the cartridge resistively (Joule effect).
  • the power source may comprise an electrical connector configured to contact the electrical connector of the cartridge when the cartridge is arranged in said compartment of the housing.
  • the electrical connector of the power source may comprise at least a first and second terminal for contacting the first and second terminals on the cartridge.
  • the terminals may be a positive and a negative terminal.
  • the electrical connector of the power source provides a connection that supplies electrical current to the electrical connector of the cartridge. In other arrangements, there may be multiple electrical connectors and/or terminals to match the number of electrical connectors and their terminals on the cartridge.
  • the aerosol-generating device further comprises an inductor electrically connected to the power source, wherein the inductor is configured to energize the susceptor in the cartridge to generate an aerosol through heating of the aerosol-generating substrate contained in the cartridge.
  • the electrical energy supplied by the power source may be converted into inductive energy through the inductor.
  • the inductive energy is preferably electromagnetic energy. The electromagnetic energy causes the susceptor material in the cartridge to generate heat.
  • the aerosol-generating device may comprise a resistive heating portion electrically connected to the power source, the resistive heating portion configured to contact the heating member connector(s) to conductively heat the heating member.
  • the power source provides electrical energy to the resistive heating portion causing it to generate heat through Ohmic heating.
  • the heat generated by the resistive heating portion is transferred to the heating member through conduction.
  • the heating member connector(s) are not necessarily electrically conductive. Instead, they are thermally conductive.
  • a method of replacing a cartridge in an aerosol generating device wherein the cartridge is the cartridge described in the above aspect, and the method comprises the steps of removing the cartridge and replacing it with a fresh cartridge.
  • a method of re-filling a cartridge as defined in the above aspect, wherein the method comprises the steps of: removing the first and/or second end cap; removing the aerosol-generating substrate contained in the internal compartment; inserting a fresh aerosol-generating substrate into the internal compartment; and replacing the first and/or second end cap to retain the fresh aerosol-generating substrate in the internal compartment.
