As used herein, the term "aerosolisable material" includes materials that give off volatile components upon heating, usually in vapor or aerosol form. An "aerosolizable material" may be a non-tobacco-containing material or a tobacco-containing material. "Aerosolizable materials" include, for example, one or more of tobacco per se, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco extracts, homogenized tobacco, and tobacco substitutes. Aerosolizable materials can be in the form of ground tobacco, cut rag tobacco, extruded tobacco, reconstituted tobacco, reconstituted aerosolizable materials, liquids, gels, gelled sheets, powders, or chunks. "Aerosolizable material" also includes other non-tobacco products, which 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 whose width and length are substantially greater than its thickness.

In this document, when a sheet is referred to as "not comprising an aerosolizable material," this means that the sheet itself neither comprises nor consists of an aerosolizable material, nor does the sheet contain an aerosolizable material. It means neither coated nor impregnated with an aerosolizable material. However, it does not mean that the sheet cannot be adjacent to (directly or indirectly) or attached to the sheet containing the aerosolizable material.

As used herein, the term "gathered" includes wrinkled, creased, folded, or rolled in shape, whether regular or irregular. Correspondingly, as used herein, the term "gathering" includes wrinkling, creasing, folding, or rolling into shapes, whether regular or irregular.

As used herein, the term "crimped" includes having a plurality of substantially parallel pleats, peaks and valleys.

As used herein, the term "heating material" or "heater material" refers to a material that can be heated by the impingement of a varying magnetic field.

Induction heating is the process by which an electrically conductive object is heated by the impingement of a varying magnetic field. This process is described by Faraday's Law of Induction and Ohm's Law. The induction heater may comprise an electromagnet and a device for passing a varying current, such as alternating current, through the electromagnet. One or more eddy currents are generated inside the object when the electromagnet and the object to be heated are preferably relatively positioned such that the resulting varying magnetic field generated by the electromagnet penetrates the object. . Objects have resistance to the flow of electric current. Thus, when such eddy currents are generated in an object, the flow against the object's electrical resistance heats the object. This process is referred to as joule heating, ohmic heating, or resistive heating. An object that can be heated by induction is known as a susceptor.

It has been found that when the susceptor is in the form of a closed circuit, the magnetic coupling between the susceptor and the electromagnet in use is enhanced, increasing or enhancing Joule heating.

Magnetic hysteresis heating is the process by which an object composed of magnetic material is heated by the penetration of a varying magnetic field. Magnetic materials are believed to include many atomic scale magnets or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipole coincides with the magnetic field. Therefore, when a varying magnetic field, such as an alternating magnetic field such as that generated by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the application of the varying magnetic field. This reorientation of the magnetic dipoles generates heat in the magnetic material.

Both Joule heating and magnetic hysteresis heating can occur in the object if the object is both electrically conductive and magnetic, due to the penetration of the fluctuating magnetic field into the object. In addition, Joule heating and magnetic hysteresis heating can be increased due to the stronger magnetic field due to the use of magnetic materials.

In each of the above processes, heat is generated inside the body itself rather than by heat transfer from an external heat source, and thus by selection of suitable body materials and shapes and suitable varying magnetic field magnitudes and orientations relative to the body, among other things. , rapid heating and more even heat distribution in the object can be achieved. In addition, induction heating and magnetic hysteresis heating do not require a physical connection between the source of the varying magnetic field and the object, allowing greater design flexibility and control over the heating profile and potentially lower costs.

Reference is made to Figures 1 and 2, which are schematic side and cross-sectional views of an example of an aerosolizable structure, according to one embodiment of the present invention. Aerosolizable structure 1 is for use in articles used in conjunction with apparatus for heating the aerosolizable material to volatilize at least one component of the aerosolizable material, such as article 100 shown in FIG. 8 and described below. is.

Although the aerosolizable structure 1 is substantially cylindrical with a substantially circular cross-section (see Figure 2), in other embodiments the aerosolizable structure 1 has an oval or elliptical cross-section. It may have a shape other than a cylindrical shape. In some embodiments, the aerosolizable structure 1 may have a polygonal, square, rectangular, square, triangular, star-shaped, or irregular cross-section, for example. In this embodiment the aerosolizable structure 1 is a rod. In some other embodiments, the aerosolizable structure may be tubular with a hollow interior region.

In this embodiment, the aerosolizable structure 1 is elongate and has a longitudinal axis AA. The length of the aerosolizable structure 1 in the direction of the longitudinal axis AA may 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 other such embodiments, the aerosolizable structure 1 still has an axial direction AA perpendicular to the cross section of the aerosolizable structure 1 shown in FIG. The width of the aerosolizable structure 1 perpendicular to the axial direction AA may be in the range of 4 to 10 millimeters, such as 5 to 8 millimeters. The circumference of the aerosolizable structure 1 perpendicular to the axial direction AA may be in the range of 12 millimeters to 30 millimeters, such as 16 millimeters to 25 millimeters.

Aerosolizable structure 1 comprises a laminated structure 10 . FIG. 3 is a partial schematic cross-sectional view of the laminate structure 10 of the aerosolizable structure 1. FIG. Laminate structure 10 includes a first sheet 11 and a second sheet 12 . In some embodiments, laminate structure 10 is a lamina. In some embodiments, first sheet 11 is bonded to second sheet 12, such as by an adhesive or chemical bond. Exemplary adhesives are polyvinyl acetate (PVA) and ethylene vinyl acetate (EVA). In other embodiments, first sheet 11 may not be bonded to 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 reconstituted aerosolizable material (eg, reconstituted tobacco) or gel form. The first sheet 11 may comprise 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 comprises a heating material that can be heated by impingement of a varying magnetic field. More specifically, the heating material can be heated by impingement with a varying magnetic field, heating 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, 12 are part of the same laminated structure 10, the heat generated in the second sheet 12 due to the penetration of the fluctuating magnetic field is closer to the first sheet 11 and Relatively efficient heating of the aerosolizable material of sheet 11 can be achieved. In some embodiments, the aerosolizable material of first sheet 11 is in surface contact with the heating material of second sheet 12 . As such, heat can be transferred directly from the heated material to the aerosolizable material. This may help further improve the efficiency of heating the aerosolizable material of the first sheet 11 . In other embodiments, the heating material may be kept out of surface contact with the aerosolizable material. For example, in some embodiments, a heat transfer barrier free of heating material and aerosolizable material may separate the heating material from the aerosolizable material. In some embodiments, the heat transfer barrier may be a coating on first sheet 11 or second sheet 12 . Providing such a barrier is advantageous as heat dissipation can help mitigate hot spots in the heated material.

In some embodiments where the aerosolizable material of the first sheet 11 is a regenerated aerosolizable material, a cellulosic aerosolizable material, or a gel form of the aerosolizable material, the aerosolizable structure 1 comprises a first sheet 11 of regenerated aerosolizable material, cellulosic aerosolizable material, or gel form of the aerosolizable material and the heating material of the second sheet 12 without any aerosolizable material. good. In some embodiments, the benefit of this is that a greater proportion of the heat generated in the second sheet 12 due to the penetration of the fluctuating magnetic field into the heated material is used to heat the aerosolizable material of the first sheet 11. It is possible.

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 is any one or more of the heating materials described herein and/or the sheet 12 containing the heating material is in any of the forms described herein. It is possible.

In this embodiment, the second sheet 12 does not contain an aerosolizable material. In some embodiments, the second sheet 12 consists solely of heating material. In other embodiments, such as those described below with reference to FIGS. 5 and 6, this may not be the case. In some embodiments, the benefit 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 due to the penetration of the fluctuating magnetic field into the heated material is can be used to heat the aerosolizable material of the first sheet 11 .

As best seen in FIG. 2, the layered structure 10 of the aerosolizable structure 1 is an aggregated layered structure 10 . In other words, the laminate structure 10 is assembled. Exemplary methods for gathering the laminate structure 10 are described in more detail below. This assembly of laminated structure 10 allows, for example, a second sheet 12 containing heating material only to be coated on the outside of a mass or assemblage of aerosolizable material, or a blade or bar of heating material to the aerosolizable material. A greater proportion of the second sheet 12 containing the heating material is located in the first sheet 11 containing the aerosolizable material to be heated compared to being relatively concentrated in the mass or clump of can be close to Therefore, the efficiency of heating the aerosolizable material of the first sheet 11 may be improved. Further, the sheet containing the aerosolizable material has a relatively large surface area to volume ratio, and by gathering the sheet containing the aerosolizable material together, a greater percentage of the surface area of the sheet is available for aerosol emission during use. can be exposed. Additionally, the gathering sheet may define one or more flow paths along which an aerosol generated in use exits the aerosolizable structure.

In one variation of the embodiment of FIGS. 1-3, the laminated structure may be corrugated. FIG. 4 is a partial schematic cross-sectional view of an example of an aggregated laminate structure of another aerosolizable structure, in which the laminate structure is corrugated, according to an embodiment of the present invention. Again, the assembled laminate structure 20 of FIG. 4 comprises a first sheet 21 comprising an aerosolizable material and heatable by impingement of a varying magnetic field to heat the aerosolizable material of the first sheet 21. and a second sheet 22 containing a heating material. Furthermore, again, the second sheet 22 does not contain an aerosolizable material. In some embodiments, the second sheet 22 consists solely of heating material. In some variations of this embodiment, the first and second sheets 21,22 are optionally or alternatively described herein with respect to the first and second sheets 11,12 shown in FIGS. may have any of the following characteristics:

Such corrugation may help and/or affect the gathering of the laminated structure 20 in the fabrication of the aerosolizable structure. For example, the distance that the laminated structure 20 corrugates can help determine the path required for winding of the laminated structure 20 during gathering and can help determine the porosity of the resulting gathered laminated structure 20 . Additionally or alternatively, such corrugation provides a higher proportion of the second sheet 22 near the first sheet 21 to reduce heating of the aerosolizable material of the first sheet 21 during use. can help improve the efficiency of Some, most or all of the plurality of substantially parallel pleats or peaks and valleys present in the laminated structure 20 as a result of corrugation are aligned in the axial direction A- of the aerosolizable structure in which the laminated structure 20 is included. It may be parallel to A.

In each of the embodiments shown in FIGS. 1-3 and 4 and described herein, the assembled laminate structure 10,20 includes two sheets 11,12,21,22. However, in some embodiments, the assembled laminate structure may include more than two sheets. FIG. 5 is a partial schematic cross-sectional view of an example of an aggregated laminate structure 30 of another aerosolizable structure, in accordance with one embodiment of the present invention.

The jumbled laminate structure 30 of FIG. 5 has a first sheet 31 , a second sheet 32 and a third sheet 33 . The second sheet 32 is arranged between the first sheet 31 and the third sheet 33 . First and second sheets 31, 33 each comprise an aerosolizable material. The aerosolizable material of the first sheet 31 can be any of the aerosolizable materials discussed herein, such as reconstituted tobacco or gel form. Similarly, the aerosolizable material of the third sheet 33 can be any of the aerosolizable materials discussed herein, such as reconstituted tobacco or gel form. One or both of the first and third sheets 31, 33 may be a cellulosic aerosolizable material.

The second sheet 32 is heatable by impingement with a varying magnetic field and comprises a heating material that heats the aerosolizable material of the first and third sheets 31,33. By placing the second sheet 32 between the first and third sheets 31, 33, the total area of the surface of the second sheet 32 is greater than that of the sheets 31, 33 containing the aerosolizable material. ratio can be approximated. This in turn allows the aerosolizable material of the laminate structure 30 to be heated by thermal energy emitted from both sides of the second sheet 32 during use.

In some embodiments, second sheet 32 does not include an aerosolizable material. In some embodiments, the second sheet 32 consists solely of heating material. However, in other embodiments, the second sheet 32 itself comprises an aerosolizable material, such as by providing a coating of the aerosolizable material or impregnating or mixing the second sheet 32 with the aerosolizable material. You can In some variations of this embodiment, one or both of the first and third sheets 31, 33 are optionally or alternatively described herein with respect to the first sheet 11 shown in FIGS. may have any of the following characteristics: In some variations of this embodiment, the second sheet 32 has any of the optional or alternative features described herein with respect to the second sheet 12 shown in FIGS. may

In one variation of the embodiment of FIG. 5, the laminated structure may be corrugated. FIG. 6 is a partial schematic cross-sectional view of an example of an aggregated laminate structure of yet another aerosolizable structure, according to an embodiment of the present invention. The patchwork laminate structure 40 of FIG. 6 is the same as the patchwork laminate structure 30 of FIG. 5, except that the patchwork laminate structure 40 of FIG. 6 is corrugated. Again, the laminated structure 40 of FIG. 6 comprises first and third sheets 41, 43 comprising an aerosolizable material, between which are heatable by the penetration of a varying magnetic field, the first and third sheets 41, 43 It includes a second sheet 42 containing a heating material for heating the aerosolizable material of the third sheets 41,43. Any of the possible variations described herein to the embodiment of FIG. 5 may be made to the embodiment of FIG. 6 to form another embodiment.

FIG. 7 is a schematic cross-sectional side view of an example of another aerosolizable structure, according to an embodiment of the present invention; Again, the aerosolizable structure 5 of Figure 7 is substantially cylindrical with a substantially circular cross-section and a longitudinal axis AA. The length and/or width of the aerosolizable structure 5 may be, for example, any one of those discussed herein with respect to the aerosolizable structure 1 of FIGS. 1-3. In other embodiments, the aerosolizable structure 5 may have a different cross-section, such as any of the cross-sections discussed herein, may be other than cylindrical, or may not be elongated.

The aerosolizable structure 5 of FIG. 7 comprises a patchwork laminate structure 50 . The assorted laminate structure 50 may be the same as any one of the assorted laminate structures 10, 20, 30, 40 described above or any of the variations thereof discussed herein.

The aerosolizable structure 5 also includes a wrapper 51 overlaid on the assembled laminate structure 50 . The wrapper 51 surrounds the assembled laminate structure 50 and may help avoid or prevent loosening or unraveling of the laminated structure 50 and helps protect the assembled laminate structure 50 from damage during shipping and use. The wrapper 51 may also help guide the flow of air through the bunched-up laminate structure 50 in use, as well as help direct the flow of vapor or aerosol through the bunched-up laminate structure 50 and out. .

In this embodiment, the wrapper 51 is wrapped in the jumbled laminate structure 50 such that the free ends overlap each other. The wrapper 51 may constitute all or most of the outer circumferential surface of the aerosolizable structure 5 . Wrapper 51 may be constructed of any suitable material, such as paper, cardboard, recycled aerosolizable material (e.g., recycled tobacco), or heating material (e.g., metal or alloy foil such as aluminum foil). . The wrapper 51 may also include an adhesive (not shown) that adheres the overlapping free ends of the wrapper 51 together. Adhesives 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 wrapper 51 from separating. In other embodiments, the adhesive may be omitted and the wrapper 51 may be of a different form than described above. Any one of these types of wrappers may be applied to other aerosolizable structures described or illustrated herein to constitute another embodiment.

Either one of the structures may be adapted to be employed as such. However, in other embodiments, the article may include an aerosolizable structure in conjunction with one or more separate components.

For example, FIG. 8 is a schematic cross-sectional side view of an example article, in accordance with one embodiment of the present invention. Article 100 of FIG. 8 includes aerosolizable structure 1 of FIGS. 1-3. However, in other embodiments, the aerosolizable structure of the article may be, for example, any other one of the aerosolizable structures described herein.

Article 100 is substantially cylindrical with a substantially circular cross-section, although in other embodiments it may have an oblong or elliptical cross-section, or be non-cylindrical. . In some embodiments, article 100 may have a polygonal, square, rectangular, square, triangular, star-shaped, or irregular cross-section, for example. In this embodiment, article 100 is a rod. In some other embodiments, the article may be tubular with a hollow interior region.

In this embodiment, article 100 is elongated and has a longitudinal axis BB. Longitudinal axis BB of article 100 coincides with longitudinal axis AA of aerosolizable structure 1 . The length of article 100 in the direction of longitudinal axis BB may be in the range of 40 millimeters to 150 millimeters, such as 70 millimeters to 120 millimeters. In other embodiments, article 100 may not be elongated. In some other such embodiments, the article 100 still has an axial direction BB perpendicular to the cross-section of the article 100 .
