As used herein, the term “aerosolisable material” includes materials that provide volatile components upon heating, typically in the form of steam or aerosol. “Aerosolizable material” can be a non-tobacco-retaining material or a tobacco-retaining material. "Aerosolizable material" includes, for example, the tobacco itself, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco extract, homogenised tobacco, or the like. It may contain one or more of tobacco substitutes. Aerosolizable materials include ground tobacco, cut rag tobacco, expanded tobacco, recycled tobacco, recyclable aerosolizable materials, liquids, gels, gelled sheets, powders or aggregates Or the like. “Aerosolizable material” may also include other non-tobacco products that may or may not contain nicotine, depending on the product. "Aerosolizable material" may include one or more humectants, such as glycerol or propylene glycol.

As used herein, the term “sheet” refers to an element having a width and length substantially greater than its thickness.

As used herein, when a sheet is said to be “free of aerosolizable material”, it is either the sheet itself does not contain an aerosolizable material or is not composed of an aerosolizable material, coated with an aerosolizable material, or It means that it is not impregnated. However, this does not mean that the sheet may or may not be adhering (directly or indirectly) to the sheet comprising an aerosolizable material.

As used herein, the term "gathered" may be wrinkled, folded, cresed, or otherwise convoluted in a regular or irregular manner. ) Includes the shape. Correspondingly, as used herein, the term “gathering” includes shapes that wrinkle, fold, fold, or otherwise wrap in a regular or irregular manner.

As used herein, the term “crimped” includes having therein a plurality of substantially parallel corrugations, or ridges and troughs.

As used herein, the terms “heating material” or “heater material” refer to a material that can be heated by penetration by a variable magnetic field.

Induction heating is the process in which an electrically conductive object is heated by a variable magnetic field penetrating the object. This process is described by Faraday's law of induction and Ohm's law. The induction heater may include an electromagnet and a device for passing a variable current such as alternating current through the electromagnet. When the electromagnet and the object to be heated are appropriately positioned such that the resulting variable magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated inside the object. The object has a resistance to the flow of currents. Thus, when such eddy currents are generated on an object, the eddy current flow to the electrical resistance of the object causes the object to heat. This process is called Joule, ohm or resistive heating. Objects that can be induction heated are known as susceptors.

It has been found that when the susceptor is in the form of a closed electrical circuit, the magnetic coupling between the susceptor and the electromagnet in use is enhanced, which results in greater or improved Joule heating.

Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by a variable magnetic field penetrating the object. Magnetic materials can be considered to include many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles are aligned with the magnetic field. Therefore, when a variable magnetic field, for example an alternating magnetic field generated by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes by the applied variable magnetic field. Such magnetic dipole redirection causes heat to be generated in the magnetic material.

If the object is both electrically conductive and magnetic, penetrating the object with a variable magnetic field can cause both joule heating and magnetic hysteresis heating to the object. Moreover, the use of a magnetic material can strengthen the magnetic field, which can strengthen joule and magnetic hysteresis heating.

In each of the above processes, since the heat is generated inside the object itself rather than by an external heat source due to heat conduction, rapid temperature rise and more uniform heat distribution in the object, in particular, suitable object materials and geometries. The selection, and suitable variable magnetic field size and orientation to the object can be achieved. Moreover, since induction heating and magnetic hysteresis heating do not require a physical connection to be provided between the source and the object of the variable magnetic field, the control and design freedom for the heating profile can be greater, and the cost can be lower. have.

1 and 2, a schematic side view and a cross-sectional view of an example of an aerosolizable structure according to an embodiment of the present invention are shown. The aerosolizable structure 1 is for use with an apparatus for heating an aerosolizable material to volatilize at least one component of the aerosolizable material, such as the article 100 shown in FIG. 8 and described below. It is for use in.

The aerosolizable structure 1 is substantially cylindrical with a substantially circular cross-section (see FIG. 2), but in other embodiments, the aerosolizable structure 1 has an oval or elliptical cross-section, or may not be cylindrical. have. In some embodiments, the aerosolizable structure 1 can have, for example, a polygon, square, rectangle, square, triangle, star or irregular cross section. In this embodiment, the aerosolizable structure 1 is a rod. In some other embodiments, the aerosolizable structure can be tubular with a hollow interior region.

In this embodiment, the aerosolizable structure 1 is elongated and has a longitudinal axis (A-A). The length of the aerosolizable structure 1 in the direction of the longitudinal axis A-A can be in the range of 40 millimeters to 150 millimeters, such as 70 millimeters to 120 millimeters. In other embodiments, the aerosolizable structure 1 may not be elongated. In some such other embodiments, the aerosolizable structure 1 still has an axial direction A-A perpendicular to the cross section of the aerosolizable structure 1 shown in FIG. 2. The width of the aerosolizable structure 1 perpendicular to the axial direction A-A can be in the range of 4 millimeters to 10 millimeters, such as 5 millimeters to 8 millimeters. The circumference of the aerosolizable structure 1 perpendicular to the axial direction A-A may be in the range of 12 millimeters to 30 millimeters, for example 16 millimeters to 25 millimeters.

The aerosolizable structure 1 includes a layered structure 10. FIG. 3 shows a schematic partial sectional view of the layered structure 10 of the aerosolizable structure 1. The layered structure 10 includes a first sheet 11 and a second sheet 12. In some embodiments, layered structure 10 is a laminate. In some embodiments, the first sheet 11 is bonded to the second sheet 12, such as by adhesive or chemical bonding. Examples of adhesives are polyvinyl acetate (PVA) and ethylene-vinyl acetate (EVA). In other embodiments, the first sheet 11 may not be bonded to the second sheet 12.

In this embodiment, the first sheet 11 comprises an aerosolizable material. The aerosolizable material of the first sheet 11 can be any of the aerosolizable materials discussed herein, such as in the form of a regenerated aerosolizable material (eg, recycled tobacco) or gel. The first sheet 11 may include a substrate such as paper impregnated or coated with an aerosolizable material such as a gel. The aerosolizable material of the first sheet 11 may be a cellulosic aerosolizable material.

In this embodiment, the second sheet 12 includes a heating material that can be heated by penetration by a variable magnetic field. More specifically, the heating material can be heated by infiltration by a variable magnetic field to heat the aerosolizable material of the first sheet 11. That is, the heating material is in thermal contact with the aerosolizable material. Since the first and second sheets 11 and 12 are part of the same layered structure 10, heat generated in the second sheet 12 due to penetration by a variable magnetic field is close to the first sheet 11 Thus, relatively efficient heating of the aerosolizable material of the first sheet 11 can be achieved. In some embodiments, the aerosolizable material of the first sheet 11 is in surface contact with the heating material of the second sheet 12. Thus, heat can be conducted directly from the heating material to the aerosolizable material. This can help further increase the heating efficiency of the aerosolizable material of the first sheet 11. In other embodiments, the heating material may not be in surface contact with the aerosolizable material. For example, in some embodiments, a thermally-conductive barrier without a heating material and an aerosolizable material can separate the heating material from the aerosolizable material. In some embodiments, the thermally conductive barrier can be a coating on the first sheet 11 or the second sheet 12. Providing such a barrier can be beneficial to help dissipate heat to alleviate hot spots in the heating material.

In some embodiments where the aerosolizable material of the first sheet 11 is in the form of a regenerated, cellulosic or gel, the aerosolizable structure 1 is a regenerated, cellulosic or gel of the first sheet 11 There may be no aerosolizable material between the aerosolizable material and the heating material of the second sheet 12. In some embodiments, the advantage of this is that a greater proportion of the heat generated in the second sheet 12 can be used to heat the aerosolizable material of the first sheet 11 by penetrating the heating material by a variable magnetic field. will be.

In this embodiment, the heating material is aluminum, and the second sheet 12 is a sheet of aluminum foil. However, in other embodiments, the heating material can be any one or more of those described herein, and/or the sheet 12 comprising the heating material can take any of the forms described herein.

In this embodiment, the second sheet 12 is free of aerosolizable material. In some embodiments, the second sheet 12 is composed of only heating material. In other embodiments as described below with reference to FIGS. 5 and 6, this may not be the case. In some embodiments, the advantage of omitting the aerosolizable material from the second sheet 12 in this manner is that a greater proportion of the heat generated in the second sheet 12 by penetrating the heating material by a variable magnetic field is the first. It can be used to heat the aerosolizable material of the sheet 11.

2, the layered structure 10 of the aerosolizable structure 1 is a corrugated layered structure 10. In other words, the layered structure 10 is corrugated. Exemplary methods for forming wrinkles in the layered structure 10 are described in more detail below. Such corrugation of the layered structure 10 is, for example, wrapping a second sheet 12 comprising a heating material around a plug of aerosolizable material or just outside the corrugation, or a heating material Compared to positioning the blade or bar of the aerosolizable material in a plug or corrugation in a relatively concentrated manner, a larger proportion of the second sheet 12 comprising the heating material will be heated It allows close proximity to the first sheet 11 comprising an aerosolizable material. Thus, improved heating efficiency of the aerosolizable material of the first sheet 11 can be achieved. Moreover, a sheet comprising an aerosolizable material can have a relatively high surface area to volume ratio, and corrugating a sheet comprising an aerosolizable material exposes a large proportion of the sheet surface area for release of aerosols in use. can do. In addition, the corrugated sheet may define one or more flow paths through which aerosols generated in use may escape from the aerosolizable structure.

In a variation on the embodiment of FIGS. 1 to 3, the layered structure can be crimped. 4 shows a schematic partial cross-sectional view of an example of a corrugated layered structure of another aerosolizable structure according to one embodiment of the invention, in which the layered structure is crimped. The corrugated layered structure 20 of FIG. 4 is again heated by infiltration by a variable magnetic field to heat the first sheet 21 comprising the aerosolizable material, and the aerosolizable material of the first sheet 21 And a second sheet 22 comprising possible heating material. In addition, there is no aerosolizable material in the second sheet 22 again. In some embodiments, the second sheet 22 is composed of only heating material. In some variations of this embodiment, the first and second sheets 21, 22 are described herein in relation to the first and second sheets 11, 12 shown in FIGS. 2 and 3. Can have any optional or alternative features.

Such crimping can help wrinkle the layered structure 20 and/or during manufacture of the aerosolizable structure, can affect how the layered structure 20 is wrinkled. For example, the distance by which the layered structure 20 is crimped can help determine the path taken by the convolutions of the layered structure 20 when corrugated, and the resulting corrugated layered structure 20 It can help determine porosity. Additionally or alternatively, such crimping can further increase the proportion of the second sheet 22 proximate to the first sheet 21, which in turn uses an aerosolizable material of the first sheet 21. It helps to increase the efficiency of heating at the time. Some, most or all of the plurality of substantially parallel corrugations or ridges and troughs present in the layered structure 20 as a result of crimping, the axial direction (AA) of the aerosolizable structure in which the layered structure 20 is included ).

In each of the embodiments shown in FIGS. 1 to 3 and 4 and described herein, the corrugated layered structure 10, 20 includes two sheets 11, 12, 21, 22. However, in some embodiments, the corrugated layered structure can include more than two sheets. 5 shows a schematic partial cross-sectional view of an example of a corrugated layered structure 30 of another aerosolizable structure according to one embodiment of the present invention.

The corrugated layered structure 30 of FIG. 5 has a first sheet 31, a second sheet 32 and a third sheet 33. The second sheet 32 is positioned between the first sheet 31 and the third sheet 33. Each of the first and second sheets 31, 33 includes an aerosolizable material. The aerosolizable material of the first sheet 31 can be in the form of any of the aerosolizable materials discussed herein, such as recycled tobacco or gel. Similarly, the aerosolizable material of the third sheet 33 can be in the form of any of the aerosolizable materials discussed herein, such as recycled tobacco or gel. One or each of the first and third sheets 31 and 33 may be a cellulosic aerosolizable material.

The second sheet 32 comprises a heating material that is heatable by infiltration by a variable magnetic field to heat the aerosolizable material of the first and third sheets 31, 33. Positioning the second sheet 32 between the first and third sheets 31, 33 is a sheet 31 in which a greater proportion of the total area of the surfaces of the second sheet 32 comprises an aerosolizable material. , 33). Eventually, this causes heat energy to be released from both surfaces of the second sheet 32 in use to heat the aerosolizable material of the layered structure 30.

In some embodiments, the second sheet 32 is free of aerosolizable material. In some embodiments, the second sheet 32 is composed of only heating material. However, in other embodiments, the second sheet 32 itself may, for example, provide a coating of an aerosolizable material, or impregnation or interweaving the second sheet 32 with an aerosolizable material. ), an aerosolizable material may be included. In some variations of this embodiment, one or each of the first and third sheets 31, 33 is any described herein in connection with the first sheet 11 shown in FIGS. 2 and 3. Can have optional or alternative features. In some variations of this embodiment, the second sheet 32 can have any optional or alternative features described herein with respect to the second sheet 12 shown in FIGS. 2 and 3. .

The corrugated layered structure 40 of FIG. 6 is the same as the corrugated layered structure 30 of FIG. 5, except that the corrugated layered structure 40 of FIG. 6 is crimped. The layered structure 40 of FIG. 6 again comprises first and third sheets 41, 43 comprising aerosolizable material, again between the first and third sheets 41, 43, And a second sheet 42 comprising a heating material heatable by penetration by a variable magnetic field to heat the aerosolizable material of the first and third sheets 41, 43. Any of the possible variations described herein for the embodiment of FIG. 5 can be made to the embodiment of FIG. 6 to form additional embodiments.

During use, the wrapper 51 can also help direct the flow of air into and through the corrugated layered structure 50, and through the corrugated layered structure 50 and corrugated It can help direct the flow of vapor or aerosol out of the layered structure 50.

In this embodiment, the wrapper 51 is wrapped around the corrugated layered structure 50 such that the free ends of the wrapper 51 overlap each other. The wrapper 51 may form all or most of the outer circumferential surface of the aerosolizable structure 5.

The adhesive may include, for example, one or more of gum arabic, natural or synthetic resins, starches and varnishes. The adhesive helps prevent the overlapping free ends of the wrapper 51 from separating. In other embodiments, the adhesive can be omitted, or the wrapper 51 can take a different shape than described. Either of these types of wrappers can be applied to other aerosolizable structures described or illustrated herein to form additional embodiments.

Broadly speaking, the apparatus 500 includes a heating zone 511 for receiving the article 200, and a variable magnetic field for penetrating the heating material of the article 200 when the article 200 is positioned in the heating zone 511. It includes a magnetic field generator 512 for generating.

More specifically, the device 500 of the present embodiment includes a body 510 and a mouthpiece 520. The mouthpiece 520 can be made of any suitable material such as plastic material, cardboard, cellulose acetate, paper, metal, glass, ceramic or rubber. The mouthpiece 520 defines a channel 522 therethrough. The mouthpiece 520 is positionable relative to the body 510 to cover the opening into the heating zone 511. When mouthpiece 520 is so positioned relative to body 510, channel 522 of mouthpiece 520 is in fluid communication with heating zone 511. In use, the channel 522 acts as a passageway to allow the volatile material to pass from the aerosolizable material of the article inserted into the heating zone 511 to the outside of the device 500.

In other embodiments, the heating zone 511 can be sized to accommodate only a portion of the article 200.

In this embodiment, the magnetic field generator 512 is a device 516 for passing a variable current such as an alternating current through an electrical power source 513, coil 514, coil 514. , A controller 517, and a user interface 518 for user operation of the controller 517.

The power source 513 of this embodiment is a rechargeable battery. In other embodiments, the power source 513 is other than a rechargeable battery, such as a non-rechargeable battery, a capacitor, a battery-capacitor hybrid, or a connection to a mains electricity supply. It may be.

The coil 514 can take any suitable form. In this embodiment, coil 514 is a helical coil of an electrically conductive material such as copper. In some embodiments, magnetic field generator 512 may include a magnetically permeable core on which coil 514 is wound. Such a magnetically permeable core concentrates the magnetic flux generated by coil 514 in use to create a stronger magnetic field. The magnetically permeable core can be made of iron, for example. In some embodiments, the magnetically permeable core can only extend partially along the length of the coil 514, concentrating the magnetic flux only in certain areas. In some embodiments, the coil can be a flat coil. That is, the coil can be a two-dimensional spiral. In this embodiment, coil 514 surrounds heating zone 511. The coil 514 extends along a longitudinal axis substantially aligned with the longitudinal axis of the heating zone 511. Aligned axes coincide. In a variant of this embodiment, the aligned axes can be parallel or oblique to each other.

In this embodiment, device 516 for passing a variable current through coil 514 is electrically connected between power source 513 and coil 514. In this embodiment, controller 517 is also electrically connected to power source 513 and communicatively coupled to device 516 to control device 516. More specifically, in this embodiment, controller 517 is for controlling device 516 to control power supply from power source 513 to coil 514. In this embodiment, the controller 517 includes an integrated circuit (IC), such as an IC on a printed circuit board (PCB). In other embodiments, the controller 517 can take other forms. In some embodiments, an apparatus can have a single electrical or electronic component that includes device 516 and controller 517.

The user interface 518 may include a push-button, a toggle switch, a dial, a touchscreen, and the like. In other embodiments, the user interface 518 can be remote and can be connected wirelessly, such as via Bluetooth, to the rest of the device.

In this embodiment, operation of the user interface 518 by the user causes the controller 517 to cause the device 516 to pass an alternating current through the coil 514. This causes coil 514 to generate an alternating magnetic field. The coil 514 and the heating zone 511 of the device 500 are used to heat the material 200 of the variable magnetic field generated by the coil 514 when the article 200 is positioned in the heating zone 511. It is properly positioned relative to penetrate. In this embodiment, the heating material is an electrically conductive material, so such penetration causes the generation of one or more eddy currents in the heating material. The flow of eddy currents in the heating material against the electrical resistance of the heating material causes the heating material to be heated by Joule heating. When the heating material is made of a magnetic material, the orientation of the magnetic dipoles in the heating material changes with the change in the applied magnetic field, which causes heat to be generated in the heating material.

The device 500 of this embodiment includes a temperature sensor 519 for sensing the temperature of the heating zone 511. The temperature sensor 519 is communicatively connected to the controller 517 so that the controller 517 can monitor the temperature of the heating zone 511. Based on one or more signals received from the temperature sensor 519, the controller 517 allows the device 516 to adjust the characteristics of the variable or alternating current passing through the coil 514 as needed, thereby heating zone ( It can be ensured that the temperature of 511) is maintained within a predetermined temperature range. The characteristic can be, for example, amplitude or frequency or duty cycle. Within a predetermined temperature range, in use, the aerosolizable material in the article located within the heating zone 511 is sufficiently heated to volatilize at least one component of the aerosolizable material without burning the aerosolizable material. do. Accordingly, controller 517 and apparatus 500 are generally arranged to heat the aerosolizable material to volatilize at least one component of the aerosolizable material without burning the aerosolizable material.

In some embodiments, the temperature range is from about 170 °C to about 220 °C. In other embodiments, the temperature range may be outside this range. In some embodiments, the upper limit of the temperature range may be higher than 300 °C. In some embodiments, temperature sensor 519 can be omitted. In some embodiments, the heating material may have a Curie point temperature selected based on the maximum temperature desired to heat the heating material, thereby further heating above that temperature by induction heating the heating material.
