DETAILED DESCRIPTION OF THE INVENTION

[0101] As used herein, an "aerosol-generating material" is a material that can generate an aerosol when excited, for example, by heating, irradiation, or in some other way. The aerosol-generating material may be in the form of a solid, liquid, or gel, which may or may not contain, for example, an active agent and / or flavoring. In some embodiments, the aerosol-generating material may comprise an "amorphous solid," alternatively referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that retains a fluid, such as a liquid, within its interior. In some embodiments, the aerosol-generating material comprises from about 50 wt%, 60 wt%, or 70 wt% amorphous solid to about 90 wt%, 95 wt%, or 100 wt% amorphous solid.

[0102] The aerosol-generating material may include one or more active agents and / or flavorants, one or more aerosol-forming materials, and one or more other functional materials, if desired.

[0103] In some embodiments, the aerosol-generating material may comprise tobacco material, which is any material containing tobacco or a derivative thereof. The tobacco material may include one or more of powdered tobacco, tobacco fiber, cut tobacco, extruded tobacco, tobacco stem, reconstituted tobacco, and / or tobacco extract. In some embodiments, the aerosol-generating material may comprise a tobacco substitute.

[0104] As used herein, a "consumable" is an item containing or consisting of an aerosol-generating material, some or all of which is intended to be consumed by a user upon use. A consumable may also include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transport component, an aerosol-generating area, a housing, a wrapper, a mouthpiece, a filter, and / or an aerosol modifier. A consumable may also include an aerosol generator, such as a heater, that radiates heat so that the aerosol-generating material generates an aerosol upon use.

[0105] As used herein, a "susceptor" is a material that can be heated by the penetration of a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material such that the penetration of the varying magnetic field results in induction heating of the heating material. The heating material may be an electrically conductive material such that the penetration of the varying magnetic field results in magnetic hysteresis heating of the heating material. The susceptor may be both electrically conductive and magnetic, such that the heating material can be heated by both heating mechanisms.

[0106] When a susceptor is integrated into a consumable, heat is generated within the susceptor itself, rather than by conduction from an external heat source, resulting in a faster temperature rise and more uniform heat distribution within the consumable. This can be achieved, among other things, by the appropriate choice of material and geometry, and the appropriate magnitude and orientation of the varying magnetic field relative to the susceptor. Furthermore, because induction heating and magnetic hysteresis heating do not require a physical connection between the source of the varying magnetic field and the susceptor, material deposits on the susceptor, such as residue or condensation, are not an issue, allowing for greater design freedom and control over the heating regime, as well as lower costs.

[0107] During the manufacture of consumables, such as those for use in non-combustion aerosol delivery devices, an aerosol-generating material, such as tobacco, is placed in contact with paper. The paper is then wrapped around the aerosol-generating material, enclosing it to form a rod. The rod is cut to a desired length, and a filter is then attached (usually at one end of the cut rod) to form the consumable.

[0108] A susceptor may be provided within such a consumable to allow the consumable to be heated in any of the above-described ways. Conventional consumables may not include a susceptor, and therefore, cutting equipment used to cut the rod to a desired length is typically configured to completely cut through the aerosol-generating material (e.g., tobacco) and one or more layers of paper. However, if the susceptor is provided as a continuous, uniform piece (e.g., a long piece of metal with uniform dimensions and material properties) throughout the rod before it is cut to a desired length, this can cause damage to existing cutting equipment used to cut the rod to a desired length online. Furthermore, not only are the equipment unsuitable for cutting susceptors in terms of strength / robustness, but the time required to cut the rod is increased when a continuous susceptor is present, thereby affecting the production rate (and quality) of the consumable that can be produced.

[0109] FIG. 1 shows a schematic diagram of a susceptor apparatus 1 for use in a method for manufacturing a consumable for use in a non-combustion aerosol delivery device according to one embodiment. The susceptor apparatus 1 includes susceptor portions 2 and connectors 3 that join the susceptor portions 2 together. The apparatus thus shows a series of susceptor portions 2 that are physically connected to one another. The physical connection can be direct (e.g., the susceptor portions 2 are integrally formed with the connectors 3) or indirect (e.g., the susceptor portions 2 are not physically connected to one another). The susceptor portions 2 are spaced apart by the connectors 3. The connectors 3 serve several functions, such as maintaining the susceptor portions 2 at a predetermined distance from one another, allowing for easier handling of the susceptor portions 2 as a single item during manufacturing, and maintaining a uniform structure for the susceptor portions 2. For example, the connectors 3 reduce the degree to which the susceptor portions 2 can twist relative to one another so that each is positioned in roughly the same position and orientation during manufacturing of the consumable.

[0110] The term "susceptor portion" herein should be understood to mean the portion of the susceptor assembly that functions primarily or exclusively as a susceptor (or heater) when the consumable containing the susceptor portion is exposed to a varying magnetic field. In some instances, the terms "susceptor" or "individual susceptor" are used instead of susceptor portion to indicate that these are portions of the susceptor device 1 that function primarily as heaters. As discussed below, the connector 3 in some embodiments includes or consists of a material that heats when exposed to a varying magnetic field, although generally the connector's primary function is not to function as a primary heat source in some implementations.

[0111] Two susceptors 2 are shown in Figure 1. However, the susceptor apparatus 1 may be configured with any suitable number of susceptors 2, for example, 2, 3, 4, 5, or 6 susceptors 2. The susceptor apparatus 1 may include an alternating row of susceptors 2 and connectors 3. The susceptor apparatus 1 may be wound on a reel or the like for convenient storage of the susceptor apparatus 1.

[0112] As shown in Figure 1, the susceptor device 1 includes susceptors 2 and weakened regions 4 of the device 1 between the susceptors 2. The connectors 3 include or consist of the weakened regions 4. The weakened regions 4 allow the susceptors 2 to be easily separated from one another when necessary. This reduces the risk of damage to any cutting equipment used to cut the susceptor device 1 during consumable manufacturing, as described below.

[0113] The weakened region 4 may be a relatively weaker region than each of the susceptors 2. For example, the weakened region 4 may be a region of the susceptors 2 that is easier to cut than each of the susceptors 2.

[0114] Generally, the or each weakened region is a region of the susceptor device 1 that has particular characteristics that make it easier to cut the weakened region relative to other regions of the susceptor device (and particularly regions containing the susceptor). In some embodiments, the weakened region 4 is formed by providing perforations in the susceptor device 1. That is, in these embodiments, the amount of material cut in the weakened region is reduced relative to other regions of the susceptor device. Alternatively or additionally, the weakened region 4 may have different geometric characteristics (e.g., width and / or length) than the susceptor 2, as shown, for example, in FIG. 3. That is, in these embodiments, the amount of material cut in the weakened region is reduced relative to other regions of the susceptor device. In other embodiments, the weakened region 4 may alternatively or additionally comprise a different material than the susceptor 2.

[0115] 1, in some embodiments, the susceptor 2 is integrally formed with the weakened region 4. Alternatively, the susceptor 2 and connector 3 may be formed as separate components and then connected together.

[0116] FIG. 2 shows a schematic diagram of a susceptor apparatus 1 according to one embodiment. As shown in FIG. 1, the susceptor apparatus 1 includes an individual susceptor 2 and a connector 3. In the embodiment of FIG. 2, the connector 3 includes a support 5 to which the susceptor 2 is secured. The susceptor 2 may be secured to the support 5 by any suitable means, such as, but not limited to, gluing or welding. The type of securing mechanism may be selected based on the material of the support 5 and the material of the susceptor 2. In some embodiments, the susceptor 2 may be crimped to the support 5 using any suitable method, effectively securing the susceptor 2 to the support 5. In some embodiments, the susceptor 2 may be encapsulated by or embedded within the support 5. For example, the support 5 may include two layers (such as two sheets of paper) that are stuck together to capture the susceptor 2 therebetween. The support 5 helps prevent the susceptor 2 from twisting or warping and keeps the susceptor 2 flat. In some embodiments, the susceptor 2 may not be flat. The support 5 helps to maintain the shape of the susceptor 2.

[0117] In some embodiments, the susceptor device 1 has markings on at least one surface thereof. For example, markings may be provided on at least one surface of the support 5. The markings aid in monitoring the movement of the support 5 and / or the susceptor device 1 during the manufacturing process. For example, the markings may be used to determine how far the support 5 should be positioned on the consumable and / or to adjust the timing of the movement of the support 5. In some embodiments, the support 5 may be provided on or wound around a bobbin.

[0118] In some embodiments, the support 5 comprises a heating material heatable by penetration with a fluctuating magnetic field. Alternatively, the support 5 does not comprise a heating material heatable by penetration with a fluctuating magnetic field. The support 5 may comprise one or more of paper, paper, metal foil, metal alloy foil, and an aerosol-generating material. In the embodiment of FIG. 2, a single support 5 is shown. In other embodiments, more than one support 5 may be utilized. For example, two supports 5 may be secured to opposing sides of the susceptor 2 such that the susceptor 2 is sandwiched between the supports 5.

[0119] The susceptor 2 and / or heating material may comprise one or more materials selected from the group consisting of an electrically conductive material, a magnetic material, and a magnetically conductive material. In some embodiments, the susceptor and / or heating material comprises a metal or metal alloy. In some embodiments, the susceptor and / or heating material comprises one or more materials selected from the group consisting of aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, steel, plain carbon steel, mild steel, stainless steel, ferritic stainless steel, molybdenum, silicon carbide, copper, and bronze.

[0120] Figure 3 shows a schematic diagram of a susceptor apparatus 1 according to one embodiment. The susceptor apparatus 1 includes a susceptor 2 and a connector 3. The connector 3 includes a support 5. As shown in Figure 3, the support may include a weakened region along line X, which is formed by changing the geometric characteristics of the support 5.

[0121] 4 is a flowchart of a method 10 for manufacturing a consumable for use in a non-combustion-based aerosol delivery device according to one embodiment. The method 10 includes providing 11 a susceptor apparatus 1 including individual susceptors 2 and connectors 3 joining the susceptors 2 to one another. The susceptor sections 2 are spaced apart by the connectors 3. The method 10 also includes forming 12 an assembly including the susceptor apparatus 1 and an aerosol-generating material, and dividing 13 the assembly. Dividing 13 includes dividing the connectors 3 and the aerosol-generating material.

[0122] In some embodiments, dividing 13 includes using a cutter to cut the connector. The cutter may be an online component of the consumable manufacturing system or may be separate from the consumable manufacturing system. The cutter may be the same cutter used to cut the consumable to a desired length.

[0123] In some embodiments, forming 12 includes at least partially burying the susceptor device 1 in the aerosol-generating material. Forming 12 may also include completely burying the susceptor device 1 in the aerosol-generating material.

[0124] In some embodiments, forming 12 includes combining the susceptor device 1 with the aerosol-generating material on a wrapper and wrapping the wrapper around the susceptor device 1 and the aerosol-generating material. The susceptor device 1 may be placed on the wrapper before the aerosol-generating material. Alternatively, the aerosol-generating material may be placed on the wrapper before the susceptor device 1.

However, it should be recognized that other relative positions of the susceptor portions 2A, 2B are possible. For example, FIG. 9 is a cross-sectional view of another embodiment in which a first susceptor portion 2A is disposed about and spaced apart from the central axis of the assembly 50. Similarly, a second susceptor portion (not shown in FIG. 9) is disposed about and spaced apart from the central axis of the assembly 50. Such a configuration of susceptor portions helps to uniformly heat the aerosol-generating material. Optionally, each susceptor portion 2A, 2B may be curved so that it extends partially around the central axis of the assembly 50. However, in other embodiments, one, more than one, or each susceptor portion may be substantially flat.

[0150] It should be appreciated that a susceptor apparatus 1 including a plurality of first susceptor portions 2A and a plurality of second susceptor portions 2B may include any of the features of the susceptor apparatus described herein (including any of the embodiments of FIGS. 1-6), but may also include features adapted to include a plurality of first susceptor portions and a plurality of second susceptor portions.
