Description

Technical Field

[0001] The present disclosure relates to an adapter sleeve comprising a susceptor into which a non-combustion heating (HNB) stick is inserted, and the combined non-combustion heating stick and sleeve are configured to be used with an induction heating device to generate an aerosol to be inhaled.

Background Art

[0002] The description of "Background Art" provided herein is for the purpose of generally presenting the context of the present disclosure. To the extent described in this section, the research of the presently named inventors, as well as aspects of the description that may not be eligible as prior art at the time of filing, are not admitted as prior art to the present invention, either expressly or implicitly.

[0003] Both vaping and HNB are alternatives to tobacco smoking that allow users to inhale nicotine and other flavors in a way that is less damaging to health than smoking. HNB is a term that involves heating a herbal material or other non-liquid material to a temperature sufficient to form an aerosol using air that passes through a material that allows the components of the aerosol to be inhaled. However, the temperature is kept below the temperature at which the material ignites or burns. The material may be tobacco, but it may also be other herbal materials or artificially synthesized materials. Typically, in currently commercially available HNB sticks, most of the material is derived from the tobacco plant, but components such as glycerin are added thereto. Examples of other herbal materials may include herbal medicines such as some traditional Chinese medicines or herbs containing cannabidiol, or materials derived from medicinal plants such as cannabis if it is legal.

[0004] Heating herb materials using induction heating has advantages, which include the ability to more uniformly disperse heat by distributing susceptor material within the herb material and low power consumption due to the heat being delivered within the volume of the herb material such that the heated volume can be thermally isolated, both of which result in reduced heat loss.

SUMMARY OF THE INVENTION

[0005] The present disclosure relates to an adapter sleeve for a non-combustion heating type (「HNB」) device. The adapter sleeve includes a sleeve body including a proximal body end, a distal body end, and a sleeve wall defining a sleeve internal space, and a peripheral susceptor disposed around the outside of the sleeve internal space and defining a heating zone. The sleeve body is configured to receive an HNB stick inserted into the sleeve internal space through the distal body end and to position the HNB stick within the sleeve internal space such that a heating portion of the HNB stick is positioned within the heating zone. The adapter sleeve is configured to be inserted into, attached to, or otherwise connected to an induction heating device to form an HNB device.

[0006] The present disclosure also relates to an HNB aerosol generation system comprising the above-described adapter sleeve, an HNB stick including an aerosol generation substrate, and an induction heating device configured to heat susceptor material present within the HNB adapter sleeve. The induction heating device is configured to inductively heat a peripheral susceptor present within the adapter sleeve, which heats the aerosol generation substrate to generate an aerosol to be inhaled.

[0007] In the following description, other embodiments may be utilized and structural and operational changes may be made without departing from the scope of the embodiments disclosed herein.

[0008] As used herein, terms such as 「a」 and 「an」 have the meaning of 「one or more」.

[0009] As used herein, the term "optional" or "optionally" means that the event or circumstance described below may or may not occur, or that the component described below may or may not be present (e.g., 0 weight %).

[0010] According to a first aspect, the present disclosure provides an adapter sleeve for a non-combustion heating ("HNB") device. The adapter sleeve includes a sleeve body including a proximal body end, a distal body end, and a sleeve wall defining a sleeve internal space, and a peripheral susceptor disposed around the outside of the sleeve internal space and defining a heating zone. The sleeve body is configured to receive an HNB stick inserted into the sleeve internal space through the distal body end and to position the HNB stick within the sleeve internal space such that a heated portion of the HNB stick is positioned within the heating zone. The adapter sleeve is configured to be inserted into, attached to, or otherwise connected to an induction heating device to form an HNB device. Such an HNB device allows a user to inhale nicotine and / or other chemicals from the material within the HNB stick while preventing direct contact between the adapter sleeve and the induction heating device.

[0011] In some embodiments, the sleeve body has a substantially tubular shape. That is, the sleeve body has an elongated length with a hollow portion (sleeve internal space) extending substantially along the elongated length and surrounded by the material forming the sleeve body (sleeve wall). Generally, the tubular shape can have any suitable cross-sectional shape. Examples of such suitable cross-sectional shapes include, but are not limited to, a circle, an ellipse, an oblong in a plane, and polygons such as a triangle, a square, a rectangle, a rhombus, a pentagon, a hexagon, etc. It should be understood that this tubular shape and cross-sectional shape refer to the overall shape of the sleeve body itself (e.g., the shape of the outer surface or periphery of the sleeve body) and are not intended to describe the shape of the sleeve internal space, which may have its own shape as described below.

[0012] In some embodiments, the sleeve body may have a shape (e.g., a cross-sectional shape) that is substantially constant throughout the length of the sleeve body. That is, the sleeve body has a single shape throughout its length. In some embodiments, the sleeve body may have a shape that is not constant throughout the length of the sleeve body. That is, there may be a portion of the sleeve body having one shape and another portion of the sleeve body having a different shape. In some embodiments, the sleeve body includes a first sleeve body portion having a first sleeve body shape and a second sleeve body portion having a second sleeve body shape. For example, the sleeve body may have a first sleeve body portion that includes a proximal body end and has a square cross-sectional shape, and a second sleeve body portion that includes a distal body end and has a circular cross-sectional shape. The shape of the first sleeve body portion that includes the proximal body end may be configured to fit snugly with the induction heating device described below. Having two or more sleeve body shapes may be advantageous to facilitate or enable a secure or convenient interaction between the first sleeve body portion that includes the proximal body end and the induction heating device, while at the same time allowing the second sleeve body portion that includes the distal body end to have a more aesthetically pleasing shape or a shape that is better configured to secure the HNB stick described below.

[0013] In some embodiments, the sleeve body may have a continuous transition in shape from the first sleeve body portion to the second sleeve body portion. That is, there may be a shape transition body portion disposed between the first sleeve body portion and the second sleeve body portion. The shape transition body portion can have a shape that changes gradually along the length of the shape transition body portion. The shape of the shape transition body portion can change from matching the first shape of the first sleeve body portion to matching the second shape of the second sleeve body portion. For example, the shape transition body portion may have a smooth and gradual change from a first sleeve body portion having a square cross-sectional shape to a second sleeve body portion having a circular cross-sectional shape.

[0014] In some embodiments, the sleeve body may have a discontinuous transition in shape from a first sleeve body portion to a second sleeve body portion. That is, there may be a sharp change in shape from the first sleeve body portion to the second sleeve body portion without a shaped transition body portion disposed therebetween.

[0015] Generally, there is no limit to the number of different shaped sleeve body portions that the sleeve body can comprise. For example, there may be a stepwise transition in shape from the proximal body end to the distal body end through any suitable number of sleeve body portions, each having a distinct sleeve body portion shape.

[0016] Having a difference in shape between the proximal body end and the distal body end can be advantageous in ensuring that the adapter sleeve is properly seated within the induction heating device. For example, the adapter sleeve may have a change in shape such that the proximal end of the adapter sleeve is seated at an appropriate depth within the heating device. That is, the first sleeve body portion has a shape configured to fit within the induction heating device and a second sleeve body portion having a shape that is prevented from being seated within the induction heating device. In this way, the shape of the adapter sleeve itself prevents the adapter sleeve from being pushed too far into the induction heating device. This is advantageous in ensuring that there is an appropriate airflow within and / or around the adapter sleeve and / or the HNB stick to ensure that the susceptor wire described below is properly positioned within the induction heating device, to prevent damage to the contact between the adapter sleeve and the induction heating device, or for a combination of these.

[0017] In some embodiments, the sleeve body has a size that is substantially constant along the length of the sleeve body. That is, the sleeve body has a single, unchanging size. In some embodiments, the sleeve body has a size that is not substantially constant along the length of the sleeve body. In some embodiments, the sleeve body has a tapered shape. That is, the sleeve body has a larger size at one end (e.g., the distal body end) than at the other end. In some embodiments, the tapered shape is configured such that the proximal body end has a larger extent (size) than the distal body end. In some embodiments, the tapered shape is configured such that the distal body end has a larger outer extent (size) than the proximal body end. That is, there can be a portion of the sleeve body having one size and another portion of the sleeve body having a different size. In some embodiments, the sleeve body includes a proximal body end and has a first sleeve body portion having a first size and a second sleeve body portion including a distal body end and having a second size. The first sleeve body portion having the first size may be the same portion as the first sleeve body portion having the first cross-sectional shape described above, or may be a different portion from the first sleeve body portion having the first cross-sectional shape described above. Similarly, the second sleeve body portion having the second size may be the same portion as the second sleeve body portion having the second cross-sectional shape described above, or may be a different portion from the second sleeve body portion having the second cross-sectional shape described above. That is, the first and second sleeve body portions of the sleeve body may differ in size, shape, or both, or may not differ at all.

[0018] In some embodiments, the sleeve body may have a continuous transition in size from a first sleeve body portion to a second sleeve body portion. That is, there may be a transition body portion disposed between the first sleeve body portion and the second sleeve body portion. The transition body portion can have a size that varies gradually along the length of the transition body portion. The size of the transition body portion can change from conforming to a first size of the first sleeve body portion to conforming to a second size of the second sleeve body portion. For example, the transition body portion can have a smooth and gradual change from a first sleeve body portion having a larger size to a second sleeve body portion having a smaller size.

[0019] In some embodiments, the sleeve body may have a discontinuous transition in size from a first sleeve body portion to a second sleeve body portion. That is, there may be a sudden change in size from the first sleeve body portion to the second sleeve body portion with no size transition body portion disposed therebetween.

[0020] Having a size difference between the proximal body end and the distal body end can be advantageous in ensuring that the adapter sleeve is properly seated within the induction heating device. For example, the adapter sleeve can have a size change such that the proximal end of the adapter sleeve is seated at an appropriate depth within the heating device. That is, the first sleeve body portion has a size configured to fit within the induction heating device and a second sleeve body portion that is too large to fit within the induction heating device. In this way, the size of the adapter sleeve itself prevents the adapter sleeve from being pushed too far into the induction heating device. This is advantageous in ensuring that there is an appropriate airflow within and / or around the adapter sleeve and / or the HNB stick to ensure that the susceptor wire described below is properly positioned within the induction heating device, in preventing damage to the contact between the adapter sleeve and the induction heating device, or for combinations thereof.

[0021] Generally, there is no limit to the number of sleeve body portions of different sizes that the sleeve body can include. For example, there can be a gradual transition in shape from the proximal body end to the distal body end through any suitable number of sleeve body portions, each having a separate sleeve body portion shape, sleeve body portion size, both, or neither.

[0022] The sleeve body is substantially hollow. That is, the sleeve wall defines an internal sleeve space. Generally, the internal sleeve space can have any suitable shape. Examples of such suitable cross-sectional shapes include, but are not limited to, a circle, an ellipse, an oblong in a plane, and polygons such as a triangle, a square, a rectangle, a rhombus, a pentagon, a hexagon, etc. In some embodiments, the internal sleeve space has the same cross-sectional shape as the cross-sectional shape of the sleeve body. In some embodiments, the internal sleeve space has a cross-sectional shape different from the cross-sectional shape of the sleeve body.

[0023] In some embodiments, the internal sleeve space can have a substantially constant shape throughout the length of the internal sleeve space. That is, the internal sleeve space has a single shape throughout its length. In some embodiments, the internal sleeve space can have a shape that is not constant throughout the length of the internal sleeve space. That is, there can be a portion of the internal sleeve space having one shape and another portion of the internal sleeve space having a different shape. In some embodiments, the internal sleeve space includes a first internal sleeve space portion having a first internal sleeve space shape and a second internal sleeve space portion having a second internal sleeve space shape. For example, the internal sleeve space can have a first internal sleeve space portion located near the proximal body end and having a square cross-sectional shape, and a second internal sleeve space portion located near the distal body end and having a circular cross-sectional shape. The shape of the second internal sleeve space portion located near the distal body end can be configured to secure the HNB stick described below.

[0024] In some embodiments, the internal space may have a continuous transition in shape from the first sleeve internal space portion to the second sleeve internal space portion. That is, there may be a shape transition internal space portion disposed between the first sleeve internal space portion and the second sleeve internal space portion. The shape transition internal space portion can have a shape that varies gradually along the length of the shape transition internal space portion. The shape of the shape transition internal space portion can change from conformity to the first shape of the first sleeve internal space portion to conformity to the second shape of the second sleeve internal space portion. For example, the transition internal space portion can have a smooth and gradual change from a first sleeve internal space portion having a square cross-sectional shape to a second sleeve internal space portion having a circular cross-sectional shape.

[0025] In some embodiments, the sleeve body may have a discontinuous transition in shape from the first sleeve internal space portion to the second sleeve internal space portion. That is, there may be a sudden change in shape from the first sleeve internal space portion to the second sleeve internal space portion with no transition internal space portion disposed therebetween.

[0026] Generally, there is no limit to the number of different shaped sleeve internal space portions that the sleeve internal space can include. For example, there can be a stepwise transition in shape from the proximal body end to the distal body end through any suitable number of sleeve internal space portions, each having a distinct sleeve internal space portion shape.

[0027] Having a difference in shape between the sleeve internal space at the proximal body end and the sleeve internal space at the distal body end can be advantageous in ensuring that the HNB stick is properly seated and / or fixed within the adapter sleeve. For example, the sleeve internal space may have a shape change such that the HNB stick cannot be inserted through to a particular depth. That is, the first sleeve internal space portion has a shape configured to allow entry of the HNB stick and a second sleeve internal space portion having a shape that does not allow entry of the HNB stick. In this way, the shape of the sleeve internal portion itself prevents the HNB stick from being pushed too far into the adapter sleeve. This is to ensure that the HNB stick is properly positioned with respect to the susceptor wire described below, to ensure that there is an appropriate airflow within and / or around the adapter sleeve and / or the HNB stick, to prevent damage to the contact between the adapter sleeve and the HNB stick, to properly position the HNB stick within the adapter sleeve and / or with respect to the induction heating device, to hold the HNB stick firmly, or for combinations thereof, which can be advantageous.

[0028] In some embodiments, the inner sleeve space has a size that is substantially constant along the length of the inner sleeve space. That is, the inner sleeve space has a single, unchanging size. In some embodiments, the inner sleeve space has a size that is not constant along the length of the inner sleeve space. In some embodiments, the inner sleeve space has a tapered shape. That is, the inner sleeve space has a larger size at one end (e.g., the end near the distal body end) than at the other end (e.g., the end near the proximal body end). In some embodiments, the tapered shape is configured such that the end of the inner sleeve space near the proximal body end has a larger inner extent (size) than the end of the inner sleeve space near the distal body end. In some embodiments, the tapered shape is configured such that the end of the inner sleeve space near the distal body end has a larger inner extent (size) than the end of the inner sleeve space near the proximal body end. In some embodiments, the inner sleeve space has a first inner sleeve space portion located near the proximal body end and having a first size, and a second inner sleeve space portion located near the distal body end and having a second size. The first inner sleeve space portion having the first size may be the same as the first inner sleeve space portion having the first cross-sectional shape described above, or may be different from the first inner sleeve space portion having the first cross-sectional shape described above. Similarly, the second inner sleeve space portion having the second size may be the same as the second inner sleeve space portion having the second cross-sectional shape described above, or may be different from the second inner sleeve space portion having the second cross-sectional shape described above. That is, the first and second inner sleeve space portions of the inner sleeve space may differ with respect to both size and shape, or may not differ at all.

[0029] Similarly, the first sleeve internal space portion having the first size and / or the first cross-sectional shape may be the same as the first sleeve body portion having the first size and / or the first cross-sectional shape described above, or may be different from the first sleeve body portion having the first size and / or the first cross-sectional shape described above. That is, the first sleeve internal space portion can be located at the same location or a different location from the first sleeve body portion. Further, the first sleeve internal space portion may have a length (or range) similar to or different from that of the first sleeve body portion. That is, the first sleeve internal space portion and the first sleeve body portion of the sleeve body can be different in terms of range and / or position. Similarly, the second sleeve internal space portion having the second size and / or the second cross-sectional shape may be the same as the second sleeve body portion having the second size and / or the second cross-sectional shape described above, or may be different from the second sleeve body portion having the second size and / or the second cross-sectional shape described above. The second sleeve internal space portion can be located at the same location or a different location from the second sleeve body portion. Further, the second sleeve internal space portion may have a length (or range) similar to or different from that of the second sleeve body portion. That is, the second sleeve internal space portion and the second sleeve body portion of the sleeve body can be different in terms of range and / or position.

[0030] In some embodiments, the sleeve internal space may have a continuous transition in size from a first sleeve internal space portion to a second sleeve internal space portion. That is, there may be a transition internal space portion disposed between the first sleeve internal space portion and the second sleeve internal space portion. The transition internal space portion can have a shape that gradually changes along the length of the transition internal space portion. The size of the transition internal space portion can change from matching the first size of the first sleeve internal space portion to matching the second size of the second sleeve internal space portion. For example, the transition internal space portion can have a smooth and gradual change from a first sleeve internal space portion having a larger size to a second sleeve internal space portion having a smaller size. The sleeve internal space can have a cross-sectional size that decreases or increases over the entire length of the sleeve internal space moving from the proximal body end to the distal body end.

[0031] In some embodiments, the sleeve internal space may have a discontinuous transition in internal space size from a first sleeve internal space portion to a second sleeve internal space portion. That is, there may be a sudden change in size from the first sleeve internal space portion to the second sleeve internal space portion with no transition internal space portion disposed therebetween.

[0032] Having a size difference between the end of the sleeve internal space near the proximal body end and the sleeve internal space near the distal body end can be advantageous in ensuring that the HNB stick is properly seated and / or secured within the adapter sleeve. For example, the sleeve internal space may have a size variation such that the HNB stick cannot be inserted through to a particular depth. That is, the first sleeve internal space portion has a size configured to allow entry of the HNB stick and a second sleeve internal space portion having a size that does not allow entry of the HNB stick (e.g., if the sleeve internal space is too small). In this way, the size of the sleeve internal portion itself prevents the HNB stick from being pushed too far into the adapter sleeve. This is to ensure that the HNB stick is properly positioned with respect to the susceptor wire described below, to ensure that there is an appropriate air flow within and / or around the adapter sleeve and the HNB stick, to prevent damage to the contact between the adapter sleeve and the HNB stick, to properly position the HNB stick within the adapter sleeve and / or with respect to the induction heating device, to hold the HNB stick firmly, or for combinations thereof.

[0033] Generally, there is no limit to the number of sleeve internal space portions of different sizes that the sleeve internal space can comprise. For example, there can be a gradual transition in shape from the end of the sleeve internal space near the proximal body end to the end of the sleeve internal space near the distal body end through any suitable number of sleeve internal space portions, each having a separate sleeve internal space portion shape, sleeve internal space portion size, both, or neither.

[0034] As described above, the sleeve wall forms the sleeve body and defines the internal space of the sleeve. The sleeve wall can be constructed from a suitable heat-resistant material. The sleeve wall, and thus the adapter sleeve itself, can be rigid, semi-rigid, or non-rigid. For example, the sleeve wall can be formed from a heat-resistant polymer such as silicone, silicone elastomer, glass, ceramic, PEEK, PFTE, PVDF polyethylene, polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyetherimide, polyamideimide, or polyimide, or a combination thereof.

[0035] In some embodiments, the sleeve wall has a uniform thickness around the width of the sleeve body. For example, if the sleeve body tubular shape has a circular cross-section and the internal sleeve space has a circular cross-section, the sleeve wall can have a uniform thickness around the perimeter of the sleeve body. In this example, the internal sleeve space can be substantially centered within the sleeve body tubular shape or concentric with the center of the sleeve body tubular shape. In another example, if the sleeve body tubular shape has a square cross-section and the internal sleeve space has a square cross-section, the sleeve wall can have a uniform thickness on each side of the sleeve body tubular shape cross-section. Similar to the previous example, the internal sleeve space can be substantially centered within the sleeve body tubular shape or concentric with the center of the sleeve body tubular shape. In some embodiments, the sleeve wall does not have a uniform thickness around the width of the sleeve body. Such non-uniform thickness can be due to or associated with different cross-sectional shapes of the sleeve body tubular shape and the internal sleeve space. For example, if the sleeve body tubular shape has a circular cross-section and the internal sleeve space has an elliptical cross-section, the sleeve wall may be thinner in the region corresponding to the major axis of the ellipse of the internal sleeve space and thicker in the region corresponding to the minor axis of the ellipse of the internal sleeve space.

[0036] In some embodiments, the sleeve wall has a uniform thickness along the length of the sleeve body. In some embodiments, the sleeve wall does not have a uniform thickness along the length of the sleeve body. In some embodiments, the sleeve wall has a uniform thickness along the length of a portion of the sleeve body (e.g., the first sleeve body portion described above). In some embodiments, the sleeve wall has an increasing thickness along the length of the sleeve body moving from the proximal body end to the distal body end. In some embodiments, the sleeve wall has a decreasing thickness along the length of the sleeve body moving from the proximal body end to the distal body end. Such increases and / or decreases can be associated with and / or caused by an increase and / or decrease in the size of the sleeve body and / or the sleeve inner space (e.g., by the tapered tubular shape described above). For example, the sleeve body can have a constant outer extent (size), and the sleeve inner space can have a decreasing tapered shape moving from the proximal body end to the distal body end. Such a decrease in the size of the sleeve inner space can be associated with or caused by an increase in the thickness of the sleeve wall.

[0037] In some embodiments, the sleeve wall includes internal protrusions disposed on the inner surface of the sleeve wall and protruding into the sleeve inner space. These internal protrusions can be advantageous for positioning, holding, or fixing the HNB stick within the sleeve inner space. The internal protrusions can be further useful for reducing the surface area of the inner surface of the sleeve wall in contact with the HNB stick and / or for providing channels or spaces for promoting the airflow between the sleeve wall and the HNB stick. Generally, the internal protrusions can be of any suitable shape, such as knobs, ridges, waves, undulations, lines, or combinations thereof. In some embodiments, the internal protrusions define an airflow channel between the inner surface of the sleeve wall and the HNB stick, and air can pass through this to facilitate the use of the adapter sleeve in generating an aerosol for the user to consume.

[0038] In some embodiments, the adapter ferrule further comprises a sleeve inner lining disposed on the inner surface of the sleeve wall. The sleeve inner lining may be disposed such that the sleeve inner lining covers the entire inner surface of the sleeve wall. The sleeve inner lining may optionally cover the peripheral susceptor. In embodiments where the peripheral susceptor is covered by a peripheral susceptor sheath as described below, the sleeve inner lining can cover the peripheral susceptor sheath or can be arranged not to cover the peripheral susceptor sheath.

[0039] The sleeve inner lining can be constructed from a suitable heat-resistant material. The sleeve inner lining can be rigid, semi-rigid, or non-rigid. For example, the sleeve inner lining can be formed from a heat-resistant polymer such as silicone, silicone elastomer, glass, ceramic, PEEK, PFTE, PVDF polyethylene, polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyetherimide, polyamideimide, or polyimide, or combinations thereof.

[0040] The distal body end is open. The distal body end is not assumed to be closed in any embodiment. That is, the distal body end is unobstructed to allow insertion of the HNB stick into the adapter sleeve. In some embodiments, the distal body end includes a stick retention structure. The stick retention structure can be a groove, clip, ridge, protrusion, recess, or other similar structure configured to interact with a portion of the HNB stick. The stick retention structure can be useful for fixing the HNB stick within the adapter sleeve, ensuring proper alignment or orientation of the HNB stick, or both. For example, the stick retention structure can be a protrusion disposed on the inner surface of the sleeve wall at a particular location. The protrusion can be configured to interact with a corresponding groove on the outer surface of the HNB stick such that the protrusion aligns with the groove opening for HNB stick insertion. When the HNB stick is inserted into the adapter sleeve, the protrusion can move within the groove. Upon reaching a particular depth, the groove can rotate or curve such that the HNB stick cannot be further inserted but can be twisted. Such twisting of the HNB stick allows the protrusion to be seated within the locking portion of the groove such that only a particular untwisting (optionally with another movement such as axial extrusion) unlocks the HNB stick from the adapter sleeve for removal.

[0041] In some embodiments, the proximal body end is open. That is, the proximal body end is not completely blocked, and the tubular shape of the sleeve body is open at both ends. In such embodiments, air can flow into the inner space of the sleeve through the open proximal body end during aerosol generation / user inhalation. In some embodiments, the proximal body end is closed. In some embodiments, the adapter sleeve further comprises an end cap disposed on the distal body end of the sleeve body. The end cap may or may not be removable. The end cap can be formed from any suitable heat-resistant material as described above. The end cap may be formed from the same material as the sleeve wall or from a different material than the sleeve wall. In some embodiments, the end cap is integral with the sleeve wall. That is, the sleeve wall closes across the proximal body end such that the sleeve wall and the end cap are formed from a single continuous piece. In some embodiments, the end cap is not integral with the sleeve wall. In such embodiments, the end cap can be fixed to the sleeve wall using any suitable method or technique such as adhesion, melt forming, ultrasonic welding, or combinations thereof, or can be fixed through the use of features or structures such as threads, fasteners, clips, grooves, press fits, interference fits, or combinations thereof. In some embodiments, the end cap is removable and is connected to the sleeve wall via a threaded connection.

[0042] In some embodiments, the end cap is solid. That is, there are no openings or vents in the end cap through which air can pass into the inner space of the sleeve. In some embodiments, the end cap has an opening or vent that allows air to pass into the inner space of the sleeve during aerosol generation / user inhalation.

[0043] In some embodiments, the adapter sleeve includes a sleeve retention structure. The sleeve retention structure can be a groove, a clip, a ridge, a protrusion, a recess, or other similar structures configured to interact with a portion of the induction heating device. The sleeve retention structure can be useful for securing the proper alignment or orientation of the adapter sleeve within the induction heating device, or both. In some embodiments, the sleeve retention structure is disposed on or located at the proximal body end. In some embodiments, the sleeve retention structure is disposed on or located at the central portion of the adapter sleeve. For example, the sleeve retention structure can be located where the induction heating device begins when the adapter sleeve is inserted to an appropriate depth within the induction heating device. In one example, the sleeve retention structure can be a wedge-shaped protrusion disposed on the outer surface of the adapter sleeve at the proximal body end. This wedge-shaped protrusion can be configured to be held by a corresponding clip structure of the induction heating device. For example, a spring-activated lever or a press-fit structure. The wedge-shaped protrusion allows insertion of the sleeve but does not allow removal of the sleeve. A button or similar release mechanism disposed on the induction heating device can activate a corresponding clip structure (e.g., a spring-activated lever or a press-fit structure) to allow removal of the adapter sleeve from the induction heating device. In this way, the adapter sleeve can be firmly held within the induction heating device. In some embodiments, the method, mechanism, or sequence of operations for removing the HNB stick from the adapter sleeve is different from the method, mechanism, or sequence of operations for removing the adapter sleeve from the induction heating device. This can be advantageous for selectively disassembling the combination of the HNB stick, the adapter sleeve, and the induction heating device.

[0044] In some embodiments, the adapter sleeve comprises a peripheral susceptor. The peripheral susceptor is disposed around the outside of the internal space of the sleeve. In some embodiments, the peripheral susceptor is disposed on the inner surface of the sleeve wall (the "inner surface of the sleeve wall"). That is, the peripheral susceptor is not embedded within the sleeve wall itself. In some embodiments, the entire thickness of the peripheral susceptor protrudes from the inner surface of the sleeve wall. This protrusion may be within the internal space of the sleeve.

[0045] In some embodiments, the peripheral susceptor is disposed partially embedded within the sleeve wall. That is, the sleeve wall covers a portion of the thickness of the peripheral susceptor, but does not cover or enclose the entire thickness of the peripheral susceptor. In some embodiments, the peripheral susceptor is disposed partially embedded within the sleeve wall such that a portion of the thickness of the peripheral susceptor protrudes into the internal space of the sleeve and the remaining portion of the thickness of the peripheral susceptor is disposed within the sleeve wall. In some embodiments, the peripheral susceptor is disposed partially embedded within the sleeve wall such that the surface of the peripheral susceptor is coplanar with the inner surface of the sleeve wall. That is, the partially embedded peripheral susceptor does not protrude from the inner surface of the sleeve wall, but the sleeve wall does not completely enclose the peripheral susceptor. In some embodiments, the peripheral susceptor is partially embedded within a groove or channel disposed within the inner surface of the sleeve wall. In some embodiments, the groove or channel has a depth such that the partially embedded peripheral susceptor protrudes from the inner surface of the sleeve wall into the internal space of the sleeve. In some embodiments, the groove or channel has a depth such that the partially embedded peripheral susceptor is coplanar with the inner surface of the sleeve wall.

[0046] In some embodiments, the peripheral susceptor is disposed completely embedded within the sleeve wall such that a portion of the sleeve wall exists between the peripheral susceptor and the inner sleeve space. In some embodiments, the peripheral susceptor is disposed completely embedded within the sleeve wall such that the inner surface of the sleeve wall has a raised or bulged portion within the region of the peripheral susceptor. That is, the inner surface of the sleeve wall has a contour that reflects the presence of the underlying peripheral susceptor. The presence of the peripheral susceptor may cause a detectable disruption or change in the inner surface of the sleeve wall near the peripheral susceptor. Such contours, rises, bulges, or bulged portions may exist for any portion of the length of the peripheral susceptor. In some embodiments, the peripheral susceptor is disposed completely embedded within the sleeve wall such that the inner surface of the sleeve wall is not changed by the presence of the peripheral susceptor. That is, the presence of the peripheral susceptor does not cause a detectable disruption or change in the inner surface of the sleeve wall near the peripheral susceptor.

[0047] In some embodiments, the peripheral susceptor is disposed on the outer surface of the sleeve wall. That is, the sleeve wall and the inner sleeve space are encompassed by the peripheral susceptor. In general, the peripheral susceptor can be made of any suitable material having the ability to be heated by induction heating.

[0048] Induction heating involves the use of an alternating electromagnetic field that induces magnetization or eddy currents within a surrounding susceptor. The susceptor may be heated as a result of hysteresis losses or induced eddy currents, which heat the susceptor through ohmic or resistive heating. In order to have the ability to be heated by induction heating, a material should be electrically conductive. Examples of materials that can be heated by induction heating include, but are not limited to, metals and metal alloys such as iron, brass, aluminum, copper, and steel, as well as semiconductors such as silicon carbide, carbon, or graphite. The metal or metal alloy can be magnetic or non-magnetic. In some embodiments, the surrounding susceptor is formed from a ferromagnetic material. The surrounding susceptor may be in the form of a continuum such as a solid wire, a hollow wire, a rod, a mesh, or a metal foam, or a discontinuum formed from a plurality of susceptor particles such as granules, flakes, fragments, blades, or rods that are positioned in contact with one another.

[0049] In some embodiments, the surrounding susceptor may have a heat loss greater than 0.05 joules / kilogram, preferably greater than 0.1 joules / kilogram. Heat loss is the capacity of the susceptor to transfer heat to the surrounding material.

[0050] In some embodiments, the peripheral susceptor may be formed from a susceptor material having a Curie temperature, which allows the heating process due to hysteresis loss only up to a specific maximum temperature. The susceptor may have a Curie temperature of about 200 degrees Celsius to about 450 degrees Celsius, preferably about 240 degrees Celsius to about 400 degrees Celsius, for example about 280 degrees Celsius. When the susceptor material reaches its Curie temperature, its magnetism changes. The susceptor material changes from a ferromagnetic phase to a paramagnetic phase at the Curie temperature. At this point, the heating based on the energy loss due to the orientation of the ferromagnetic regions stops. Thereafter, further heating is mainly based on the formation of eddy currents such that the heating process is automatically reduced when the Curie temperature of the susceptor material is reached. The susceptor material and its Curie temperature are preferably adapted to the composition of the aerosol generation substrate in order to achieve an optimal temperature and temperature distribution within the aerosol generation substrate for optimal aerosol generation. The use of a susceptor material having the Curie temperature described herein can be advantageous for preventing or reducing overheating of the susceptor wire.

[0051] In some embodiments, the peripheral susceptor is made of ferrite. Ferrite is a ferromagnetic material having a high magnetic permeability and is particularly suitable as a susceptor material. The main component of ferrite is iron. Other metal components (e.g., zinc, nickel, manganese) or non-metal components (e.g., silicon) may be present in various amounts. In some embodiments, the peripheral susceptor comprises fully sintered ferrite powders such as FP160, FP215, and FP350 by PPT, Indiana, USA.

[0052] In some embodiments, the peripheral susceptor sheath is disposed on the peripheral susceptor. The peripheral susceptor sheath may be a structure in which the peripheral susceptor is seated therein (e.g., the sheath is self-supporting), or may be a coating on the peripheral susceptor (e.g., the sheath is not self-supporting). The peripheral susceptor sheath may conform to the peripheral susceptor (e.g., there is no gap between the peripheral susceptor and the sheath), or may not conform to the peripheral susceptor (e.g., there is a gap between the peripheral susceptor and the sheath). Such gaps may be uniform or non-uniform throughout the length of the peripheral susceptor sheath. The peripheral susceptor sheath may be constructed from a suitable heat-resistant material. The peripheral susceptor sheath may be rigid or semi-rigid. For example, the peripheral susceptor sheath may be formed from a heat-resistant polymer such as glass, ceramic, PEEK, PFTE, PVDF polyethylene, polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyetherimide, polyamideimide, or polyimide, or combinations thereof. The peripheral susceptor sheath may be advantageous in providing additional thermal mass useful for heating the HNB stick and / or preventing contact between the HNB stick and the peripheral susceptor. The peripheral susceptor sheath may also be advantageous in providing additional mechanical integrity to the peripheral susceptor, particularly to prevent damage during cleaning.

[0053] The peripheral susceptor defines a heating zone. This heating zone can be part of the adapter sleeve that reaches a specific minimum temperature, such as the temperature required for aerosol formation from the HNB stick. In some embodiments, the peripheral susceptor is configured to define a heating zone such that the heating zone is substantially cylindrically symmetric. In some embodiments, the peripheral susceptor is configured to define a heating zone such that the heating zone is not cylindrically symmetric. In some embodiments, the peripheral susceptor is configured to extend around the entire outer perimeter of the inner space of the sleeve. That is, the heating zone is surrounded by the peripheral susceptor. Such a configuration can be advantageous for ensuring a uniform heat distribution to the HNB stick. This can prevent the formation of hot spots and allow a portion of the HNB stick to burn or remain at too low a temperature for aerosol formation. In some embodiments, the peripheral susceptor is configured to extend over the entire length of the heating zone. That is, the heat from the peripheral susceptor does not extend significantly in the proximal or distal direction along the length of the adapter sleeve from the peripheral susceptor. This heat distribution can be due to rapid cooling or inefficient heat transfer from the peripheral susceptor to the HNB stick or sleeve wall outside the heating zone.

[0054] The peripheral susceptor can have any suitable shape for defining a heating zone. For example, the peripheral susceptor can have a zigzag shape, a sinusoidal shape, a coil shape, or a combination thereof. The peripheral susceptor is preferably configured such that the length of the peripheral susceptor is oriented at an angle of less than 75°, preferably less than 70°, preferably less than 65°, preferably less than 60°, preferably less than 55°, preferably less than 50°, preferably less than 45°, preferably less than 40° with respect to the length of the sleeve body. Such an orientation can be advantageous for ensuring efficient inductive heating by a preferred alignment of the length of the peripheral susceptor with the magnetic field generated by the inductive heating device.

[0055] In some embodiments, the adapter sleeve comprises a central susceptor. The central susceptor is disposed within the inner space of the sleeve. In some embodiments, the central susceptor is disposed over the entire length of the heating zone. In some embodiments, the central susceptor is not disposed over the entire length of the heating zone. For example, the central susceptor may end before the heating zone ends. That is, the central susceptor is shorter than the heating zone. In some embodiments, the central susceptor is positioned substantially centrally within the inner space of the sleeve. Such positioning can be achieved by using a central susceptor support. The central susceptor support can be attached to the central susceptor and the sleeve wall such that the central susceptor is supported away from the inner surface of the sleeve wall. The central susceptor support can be formed from any suitable heat-resistant material described above. The central susceptor support is preferably rigid. The rigidity of the central susceptor support can be advantageous in keeping the central susceptor centered during insertion and / or removal of the HNB stick.

[0056] In some embodiments, the central susceptor is attached to an end cap. In embodiments where the end cap is removable, the central susceptor can also be removed. That is, removal of the end cap results in removal of the central susceptor. Removability can be advantageous for cleaning the central susceptor, the sleeve wall, or both.

[0057] The central susceptor can be made of any suitable material capable of being heated by induction heating as described above. In some embodiments, the peripheral susceptor is formed from a ferromagnetic material. The peripheral susceptor may be in the form of a continuous body such as a solid wire, a hollow wire, a rod, a mesh, or a metal foam, or a discontinuous body formed from a plurality of susceptor particles such as granules, flakes, fragments, blades, or rods positioned in contact with each other. In some embodiments, the central susceptor is formed from a pair of wires. The pair of wires can be twisted around a central axis of twist.

[0058] In some embodiments, the central susceptor sheath is disposed on the central susceptor. Generally, the central susceptor sheath can be constructed from a suitable heat-resistant material. The central susceptor sheath may be a structure in which the central susceptor is stationary therein (e.g., the sheath is self-supporting), or it may be a coating on the central susceptor (e.g., the sheath is not self-supporting). The central susceptor sheath may be rigid or semi-rigid. For example, the central susceptor sheath can be formed from a heat-resistant polymer such as glass, ceramic, PEEK, PFTE, PVDF polyethylene, polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyetherimide, polyamideimide, or polyimide, or a combination thereof. The central susceptor sheath can be advantageous in providing additional thermal mass useful for heating the HNB stick, particularly during heating, and / or preventing contact between the HNB stick and the central susceptor. The central susceptor sheath can also be advantageous in providing additional mechanical integrity to the central susceptor, particularly for preventing damage during cleaning or insertion / removal of the HNB stick. In some embodiments, the central susceptor sheath conforms to the central susceptor. For example, in embodiments where the central susceptor is formed from a pair of wires twisted about a central torsional axis, the central susceptor sheath can conform to the pair of wires to form a screw-like shape. Such a screw-like shape can be advantageous in facilitating insertion of the HNB stick into the adapter sleeve, particularly by facilitating penetration of the aerosol-generating substrate by the central susceptor. In some embodiments, the central susceptor sheath does not conform to the central susceptor (e.g., there is a gap between the central susceptor and the sheath). Such gaps can be uniform or non-uniform over the entire length of the central susceptor sheath.

[0059] In some embodiments, the adapter sleeve comprises both a peripheral susceptor and a central susceptor as described above. In some embodiments, the adapter sleeve comprises a peripheral susceptor but does not include a central susceptor. Such embodiments may be particularly advantageous when the HNB stick includes a susceptor such as a susceptor located at its center. In such situations, the central susceptor of the adapter sleeve may interfere with, displace, or damage the susceptor of the HNB stick. Thus, it may be advantageous to provide an adapter sleeve that does not include a central susceptor. In some embodiments, the central susceptor from the adapter sleeve may be removable from the adapter sleeve. For example, if the central susceptor is attached to or disposed on a removable end cap, the removable end cap can be removed, and the adapter sleeve can be used without the end cap or the central susceptor attached thereto, and can be inserted or attached into the adapter sleeve. That is, the end cap having the central susceptor can be replaced with an end cap without a central susceptor.

[0060] In some embodiments, the adapter sleeve comprises a central susceptor but does not include a peripheral susceptor. Such embodiments may be particularly advantageous when the HNB stick includes a susceptor such as a susceptor located at its periphery. It may be disadvantageous to bring the HNB stick susceptor into proximity or contact with the adapter sleeve peripheral susceptor. Thus, for an HNB stick having its own susceptor, an adapter sleeve lacking a peripheral susceptor but having a central susceptor can be used.

[0061] In some embodiments, the adapter sleeve does not include either a peripheral susceptor or a central susceptor. Such embodiments may be referred to by terms such as "empty sleeve", "susceptorless sleeve", "susceptacle-free sleeve", or other similar terms. Such embodiments may be particularly advantageous when the HNB stick includes a susceptor. It may be disadvantageous to bring the HNB stick susceptor into proximity or contact with the adapter sleeve peripheral susceptor and / or the adapter sleeve central susceptor. Such close contact can result in damage to the HNB stick, damage to the adapter sleeve, combustion of the aerosol-generating substrate, overheating, wicking, other unpleasant user experiences, or combinations thereof. Thus, in some situations, such as with an HNB stick having its own susceptor, an adapter sleeve lacking both a peripheral susceptor and a central susceptor can be used.

[0062] In some embodiments, the adapter sleeve further comprises an insulating layer. The insulating layer is preferably disposed outside the peripheral susceptor. The insulating layer may be advantageous for reducing heat loss from the peripheral susceptor in a direction away from the aerosol-generating substrate, protecting the induction heating device from damage caused by heat transfer from the adapter sleeve, or both. In some embodiments, the insulating layer is disposed within the sleeve wall. In some embodiments, the insulating layer is disposed on the outer surface of the sleeve wall. In some embodiments, the peripheral susceptor is disposed within the insulating layer. For example, the insulating layer may be disposed on the outer surface of the sleeve wall, and the peripheral susceptor may be embedded within the insulating layer such that the peripheral susceptor contacts the outer surface of the sleeve wall.

[0063] In some embodiments, the adapter sleeve includes an identifier. In some embodiments, the identifier is an electronic identifier such as a radio frequency identification (RFID) device, a near field communication (NFC) device, etc. In some embodiments, the identifier is an optical identifier such as a barcode, a 2D barcode such as a QR code (registered trademark), etc. The identifier can store or encode information corresponding to the adapter sleeve and / or the HNB stick compatible with the adapter sleeve. For example, the identifier can store or encode information related to the optimal and / or maximum operating temperature of the adapter sleeve, the magnetic properties and / or resonance frequency of the susceptor (peripheral susceptor, central susceptor, or both), or a combination thereof. The identifier can be configured to be readable by an induction heating device to provide the information stored or encoded by the identifier.

[0064] The adapter sleeve is configured to allow air to flow into the adapter sleeve through the distal body end. The HNB stick inserted into the adapter sleeve through the distal body end should allow for an air flow between the outside of the HNB stick and the inner surface of the sleeve wall. The HNB stick should not form a sealing seal that prevents air from flowing. The inner protrusion and / or the peripheral susceptor (or, where applicable, the peripheral susceptor sheath) can contact the HNB stick in some areas, but should not contact the entire perimeter or periphery of the HNB stick in such a way that a seal is formed that obstructs the air flow. In embodiments where the proximal body end is open and / or the end cap has an opening or vent hole, air can flow into the sleeve internal space through the open proximal body end or the opening / vent hole. The air flowing into the sleeve internal space can pass into the HNB stick and optionally through the aerosol generating substrate. The air can then flow through the HNB stick in the direction of the distal body end of the adapter sleeve (i.e., away from the induction heating device) for inhalation by the user.

[0065] One distinct advantage of the adapter sleeve of the present application is that the adapter sleeve prevents contact between the HNB stick (and the aerosol generating substrate contained therein) and the induction heating device. The HNB stick typically leaves a residue near the end of the stick during use. This residue can be unsightly, affect the flavor, affect the performance of the induction heating device, or a combination of these. Typically, the residue needs to be removed. However, the use of the adapter sleeve can deposit the residue on the adapter sleeve itself rather than on the induction heating device. In this way, the induction heating device can be kept clean. Further, the adapter sleeve can be easily removed from the induction heating device, allowing the user to use a new or unused adapter sleeve or to easily clean a soiled adapter sleeve. In a preferred embodiment, the adapter sleeve can be immersed in water or other solvents or cleaning fluids without adverse effects. Further, in embodiments where the adapter sleeve comprises a removable end cap, the end cap can be removed to enhance ease of cleaning.

[0066] The present disclosure also relates to an HNB aerosol generation system comprising the above-described HNB adapter sleeve, an HNB stick comprising an aerosol generating substrate, and an induction heating device configured to heat susceptor material present within the HNB adapter sleeve. In some non-limiting embodiments, the HNB stick comprising the aerosol generating substrate is inserted into the HNB adapter sleeve, and then the combined stick and sleeve are inserted into the induction heating device to form the device. In other non-limiting embodiments, an HNB adapter sleeve suitable for the HNB stick being used is first inserted into the induction heating device, and then the HNB stick is inserted into the combined HNB adapter sleeve and induction heating device to form the HNB device. The HNB device is configured to heat susceptor material present within the HNB adapter sleeve to generate an aerosol to be inhaled.

[0067] As used herein, the terms "non-combustible heated stick" and "HNB stick" refer to aerosol-generating articles containing a non-liquid aerosol-generating substrate. Although typically substantially tubular in shape, there are no general restrictions on the shape that an HNB stick can take. An HNB stick can include, or can comprise, a stick body that contains, holds, or secures the aerosol-generating substrate. The stick body can be configured to allow air or other gas to flow through or around the aerosol-generating substrate. Such an air flow can be advantageous for the delivery of the generated aerosol to the user. An HNB stick can include, or can comprise, the susceptor described above. Such a susceptor can be located centrally (e.g., substantially centrally disposed within the stick body, such as concentric and coaxial within a cylindrical HNB stick) or peripherally (e.g., disposed substantially adjacent to or along the outer periphery of the HNB stick, such as just inside the outer surface of a cylindrical HNB stick). An HNB stick can include either or both of a peripherally located susceptor and a centrally located susceptor.

[0068] The aerosol generating substrate may be tobacco, or may contain tobacco, but may also be other herbal materials and synthetic materials, or may contain them. The typical aerosol generating substrate used in HNB sticks is non-liquid. That is, the aerosol generating substrate is not liquid, but can be in the form of a solid, gel, paste, bingham plastic, or a combination thereof. The aerosol generating substrate can be in the form of an integrated mass, granule, fragment, chip, particle, or other suitable shape, or a combination thereof. Typically, in currently commercially available HNB sticks, most of the aerosol generating substrate is derived from the tobacco plant, but components such as glycerin are added. Examples of other herbal materials may include herbal medicines such as some traditional Chinese medicines or herbs containing cannabidiol, or materials derived from medicinal plants such as cannabis if it is legal. The aerosol generating substrate generates an aerosol when heated.

[0069] The following examples are intended to further illustrate the construction of the adapter sleeve and the protocol for the construction and use of the HNB aerosol generating system, and are not intended to limit the scope of the claims.

[0070] When numerical limits or ranges are described herein, the endpoints are included. Also, all values and sub-ranges within the numerical limits or ranges are specifically included as if they were explicitly described.

[0071] Of course, numerous modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, it should be understood that the present invention may be practiced in ways other than specifically described herein.

[0188] Here, the embodiments will be further described with reference to the drawings.

[0189] FIG. 1 shows a non-limiting exemplary embodiment of the adapter sleeve of the present application. The exemplary adapter sleeve 101 is designed to be used with an HNB stick having a diameter of approximately 7 mm and a plug of an aerosol generation substrate having a length of approximately 10 mm. The adapter sleeve of FIG. 1 is partially transparent so that the components can be seen. FIG. 1 shows a proximal body end 102, a distal body end 103, and a sleeve wall 104. Also shown are a peripheral susceptor 110 in the form of a zigzag wire disposed within the sleeve wall 104 and defining a heating zone 120, and a central susceptor 111 shown as a pair of twisted wires. The adapter sleeve is shown having a single stick holding structure 130 shown as a protrusion into the sleeve internal space located at the distal body end 104, and a single sleeve holding 140 structure shown as an outward protrusion disposed on the proximal body end 103.

[0190] Figures 2A - 2C show three views of an exemplary HNB stick 201 and an HNB adapter sleeve 101. In Figure 2A, the HNB stick 201 includes an aerosol - generating substrate 202 and a non - substrate portion 203. The HNB stick 201 has not yet been inserted into the adapter sleeve 101. In Figure 2B, the HNB stick 201 is inserted into the HNB adapter sleeve to form an assembly 210 that is ready to be inserted into an induction heating device. As shown, the aerosol - generating substrate 202 is positioned within the heating zone 120. Figure 2C shows a cross - section of the combined HNB adapter sleeve and HNB stick. In this non - limiting embodiment, the peripheral susceptor is in the form of a zig - zag wire that extends beyond the end of the aerosol - generating substrate 202 that is vaporized within the HNB stick, while the central susceptor, in the form of a pair of twisted wires, is not. The entire heating zone 120 is defined by the peripheral susceptor and extends beyond the aerosol - generating substrate 202.

[0191] Figure 3 shows a non - limiting embodiment of an induction heating coil 301 with an HNB adapter sleeve 101 inserted therein. In some embodiments, the coil shape is configured to efficiently heat the susceptor material. In other embodiments, using a larger - diameter coil to enable the use of a wider HNB stick with different HNB adapter sleeve diameters and then configuring to accommodate different HNB sticks may sacrifice heating efficiency. The induction heating coil is shown as the only component, but is understood to be part of a complete induction heating device. For example, as shown in Figure 5, the coil is housed inside the induction heating device and may surround the HNB adapter sleeve.

[0192] Figure 4A shows an exemplary central susceptor formed from a pair of twisted wires encapsulated by a central susceptor sheath formed from an inert material such as glass or ceramic. Figure 4B shows an exemplary peripheral susceptor in the form of a zigzag susceptor wire. Figure 4C shows an exemplary peripheral susceptor in the form of a sinusoidal wire having rounded corners rather than sharp corners present in the zigzag susceptor shown in Figure 4B.

[0193] Figure 5 shows the HNB stick 201 and the HNB adapter sleeve 101 that are inserted into and combined within the induction heating device 501 to form the HNB device 510. The use of the HNB adapter sleeve can be implemented in different ways in different non-limiting embodiments. For example, the HNB adapter sleeve can be inserted into the induction heating device and held within the device by a sleeve retention structure such as a groove around an end cap. Then, several HNB sticks of the same type can be consumed before the HNB adapter sleeve is removed, for cleaning or to replace it with a different adapter sleeve for use with a different HNB stick type. In another non-limiting embodiment, the adapter sleeve is configured to fit closely around the HNB stick such that the HNB stick is first inserted into the HNB adapter sleeve and then the combined HNB sleeve and HNB adapter stick are inserted into the induction heating device. After each HNB stick is consumed, the used stick and the HNB adapter sleeve are then removed together again.
