A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucolyptol, WS-3.Aerosol-Generating Material

[0048] Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, be in the form of a solid, liquid or semi-solid (such as a gel) which may or may not contain an active substance and / or flavorants.

[0049] The aerosol-generating material may comprise one or more active substances and / or flavors, one or more aerosol-former materials, and optionally one or more other functional material.

[0050] The aerosol-generating material may comprise a binder, such as a gelling agent, and an aerosol former. Optionally, a substance to be delivered and / or filler may also be present. Optionally, a solvent, such as water, is also present and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. In some embodiments, the aerosol-generating material is substantially free from botanical material. In particular, in some embodiments, the aerosol-generating material is substantially tobacco free.

[0051] The aerosol-generating material may comprise or be in the form of an aerosol-generating film. The aerosol-generating film may comprise a binder, such as a gelling agent, and an aerosol former. Optionally, a substance to be delivered and / or filler may also be present. The aerosol-generating film may be substantially free from botanical material. In particular, in some embodiments, the aerosol-generating material is substantially tobacco free.

[0052] The aerosol-generating film may have a thickness of about 0.015 mm to about 1 mm. For example, the thickness may be in the range of about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm.

[0053] The aerosol-generating film may be continuous. For example, the film may comprise or be a continuous sheet of material. The sheet may be in the form of a wrapper, it may be gathered to form a gathered sheet or it may be shredded to form a shredded sheet. The shredded sheet may comprise one or more strands or strips of aerosol-generating material.

[0054] The aerosol-generating film may be discontinuous. For example, the aerosol-generating film may comprise one or more discrete portions or regions of aerosol-generating material, such as dots, stripes or lines, which may be supported on a support. In such embodiments, the support may be planar or non-planar.

[0055] The aerosol-generating film may be formed by combining a binder, such as a gelling agent, with a solvent, such as water, an aerosol-former and one or more other components, such as one or more substances to be delivered, to form a slurry and then heating the slurry to volatilize at least some of the solvent to form the aerosol-generating film.

[0056] The slurry may be heated to remove at least about 60 wt %, 70 wt %, 80 wt %, 85 wt % or 90 wt % of the solvent.

[0057] The aerosol-generating material may comprise an aerosol former, a binder, optionally a filler and optionally an active and / or a flavorant.

[0058] The aerosol-former material may comprise one or more constituents capable of forming an aerosol. In some embodiments, the aerosol-former material may comprise one or more of glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0059] The one or more other functional materials may comprise one or more of a pH regulators, coloring agents, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0060] The aerosol generating material may be present on or in a support, the support forming a substrate. The support may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or either side of the material.

[0061] A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

[0062] An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavor, acidity or another characteristic of the aerosol. The aerosol-modifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent

[0063] The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavorant, a colorant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0064] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol.

[0065] FIG. 1 illustrates a consumable 100 for use with a non-combustible aerosol provision device, such as the non-combustible aerosol provision device 200 schematically illustrated by FIG. 4. The consumable 100 comprises a core 101 comprising a twisted rope-like structure of at least two strands 102 of material. At least one of the strands 102 of material comprises aerosol generating material 105.

[0066] The non-combustible aerosol provision device 200 comprises an area 201 for receiving the consumable 100 and an aerosol generator 202. The aerosol generator 202 is configured to heat the aerosol generating material 105 of the consumable 100 when it is received in the area 201 to generate an aerosol for inhalation by a user, as will be explained further below.

[0067] FIGS. 2a to 2e show example consumables 100 in cross section. Each cross section is projected onto a plane that bisects the consumable 100 perpendicular to its longitudinal axis. In each example, the core 101 of each consumable 100 comprises three strands 102, though it will be appreciated any of the examples may comprise only two strands 102 or more than two strands 102, such as four or five strands 102. It will also be appreciated that, while the illustrated strands 102 comprise a circular cross section, other cross sectional shapes may be used as long as the resulting strands can be twisted together to form a rope-like structure. In some examples described herein, the diameter of each strand 102 is between 0.1 mm and 5 mm, or between 1 mm and 3 mm. In one example, the diameter of each strand 102 is about 2 mm.

[0068] In the example of FIG. 2a, each strand is formed from an absorbent material 104. The absorbent material 104 is provided with an aerosol generating material 105. For example, the aerosol generating material 105 may be provided as an additive to the absorbent material 104. In some examples, the absorbent material 104 may be doped with the aerosol generating material 105 in a liquid form so that the aerosol generating material 105 is absorbed by the absorbent material 104. The absorbent material 104 may be any material for suitable for absorbing aerosol generating materials 105 described herein. The absorbent material 104 may be a fibrous material and may be plant based. In one example the absorbent material 104 is a crimped and gathered paper. The aerosol generating material 105 may comprise an aerosol former material, as defined above. Therefore, when the consumable 100 is heated in use, the aerosol former material evaporates to form an aerosol for inhalation by a user. The aerosol generating material 105 may also comprise one or more active substances, one or more flavors and / or one or more other functional materials, as defined above. In one example, the absorbent material 104 is provided with an aerosol generating material 105 that comprises an aerosol former material comprising glycerol, a flavor and an active substance comprising nicotine. Optionally, the absorbent material 104 is a reconstituted tobacco material that is formed as an absorbent tobacco paper. Therefore, the absorbent material 104 additionally provides flavor to the aerosol former material when the consumable is heated during use.

[0069] Where strands 102 of reconstituted tobacco material are used, the strands 102 may be provided in strips of reconstituted tobacco material. The reconstituted tobacco strands can be longitudinal strips. The reconstituted tobacco material can be, for example, band cast reconstituted tobacco material or paper reconstituted tobacco material. In some embodiments, the strands are provided as flat strips of reconstituted tobacco. The strips may have a width of between 0.25 mm and 2 mm; a thickness of 30 to 1000 μm, or 30 to 300 μm; and a density in the range of about 20 to 250 grams per square meter. The strips may have a ratio of the width to the thickness of between 0.25 and 70, or between 1 and 10.

[0070] To form the core 101, the strips are arranged in parallel and collected in a bundle before being twisted into a rope like structure in accordance with the method 60 described below with reference to FIG. 6. Any number of strands may be used, but in some examples, between 100 and 300 number of strands may be used to form the core. In some examples, the core may have a density of between 0.1 g / cm3 and 0.9g / cm3.

[0071] An advantage of twisting strips of reconstituted tobacco material into a rope like structure is that the strips become interlocked, making them less easily displaced. This is particularly beneficial when the consumable is used with a non-combustible aerosol provision device 200 comprising a pin or blade-like heater that extends into the area 201 for receiving the consumable 100. A pin or blade-like heater is configured to penetrate the consumable 100 along its axis to heat the aerosol generating material 105. It has been found that consumables comprising strands of reconstituted tobacco material that are not formed into a twisted rope like structure tend to be displaced by such heaters, leaving debris with the area 201 for receiving the consumable. During longer term use of the device, this debris can accumulate to the detriment of heater efficiency and hygiene.

[0072] In another example illustrated by FIG. 2b, each strand comprises a homogenized structure 106 of aerosol generating material 105, wherein the aerosol generating material 105 comprises an aerosol former, a binder, optionally a filler, and optionally an active and / or a flavorant. In the illustrated example, each strand 102 is a monolithic solid. That is to say, each strand is cast as single piece. For example, each strand 102 may be an extruded section of the aerosol generating material 105. When the consumable 100 is heated in use, volatile constituents of the aerosol generating material 105 evaporate to form an aerosol for inhalation by a user.

[0073] The example consumable 100 illustrated by FIG. 2c is the same as the example of FIG. 2b with the exception that each strand 102 further comprises a material 107 heatable by penetration with a varying magnetic field, herein referred to as a susceptor 107. In the illustrated example, a susceptor 107 is embedded in each strand 102 of the consumable 100. Such example consumables 100 are configured for use with a device 200 comprising an aerosol generator 202 configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100, as explained further below. Therefore, when the consumable 100 is used with such a device 200, the susceptor 107 of each strand 102 is heated by the varying magnetic field to heat the aerosol generating material 105 and form an aerosol for inhalation by the user. In the illustrated example, the susceptor 107 of each strand 102 comprises a twisted rope-like structure. However, it will be appreciated that the susceptors 207 may take any form suitable for their integration into the strands 102. Therefore, the susceptors 207 are preferably formed of a resiliently flexible material that allows them to follow the helical path of the strands 102 in which they are embedded. In the illustrated example, each susceptor 107 is embedded substantially centrally within a strand 102. Such example consumables 100 may be formed by extruding a strand 102 of aerosol generating material 105 around a continuous length of susceptor 107. Each strand 102 is then cut to length and twisted about at least one other such strand 102 to form the rope-like structure of the core 101, as will be explained further below.

[0074] In another unillustrated example, each strand 102 comprises a susceptor 107 embedded in a strand 102 formed from a material other than a homogenized structure 106 of aerosol generating material 105. It will be appreciated that a susceptor 207 may be embedded in any of the strands 102 described herein. For example, a susceptor 207 may be embedded in strands 102 of absorbent material, such as the strands 102 described in connection with FIG. 2a. Such example strands 102 may be formed by gathering absorbent material 104 around a continuous length of susceptor 107. Each resulting strand 102 is then cut to length and twisted about at least one other such strand 102 to form the rope-like structure of the core 101, as will be explained further below with reference to the method of FIG. 6.

[0075] The example consumable illustrated by FIG. 2d further comprises an outer wrapping material 108 that circumscribes the core 101. The illustrated strands 102 are representative of any of the strands 102 described above, including strands 102 of absorbent material 104 and strands of comprising a homogenized structure 106 of aerosol generating material 105. In such examples the consumable 100 is provided with a smooth, generally cylindrical appearance. The outer wrapper 108 forms an outer surface of the consumable 100. Therefore, wrapping the core 101 in an outer wrapper 108 prevents the user from having to handle the core 101 directly. This may be beneficial to stop the user getting any of the aerosol generating material 105 on them where they touch the consumable 100. A further advantage of the outer wrapper108 is that air flow channels 109 are formed between the outer wrapper 108 and the core 101. The air flow channels 109 follow the helical groove formed between strands 102 of the rope-like structure. The air flow channels 209 form a helical air flow pathway that extends from a distal end 100″ of the consumable to a mouth end 100′. On account of their helical shape, the length of the helical air flow pathway formed by the air flow channels 209 is greater than if the air flow pathway were straight. That is to say, the length of the helical air flow pathway is greater than a straight air flow pathway that extends over the same axial length of the consumable 100. Therefore, the residence time of air drawn through the consumable 100 is greater than if the air flow pathway were straight. This allows more of the constituent parts of the aerosol formed during use to be entrained into the air drawn along the air flow pathway. Another effect of the helical airflow pathway is that the pressure drop across the consumable is greater than if the airflow pathway were straight.

[0076] It will be appreciated that the length of the airflow pathway can be affected by the pitch P of the helix formed by each strand 102 of the core 101. The pitch P of the helix formed by each strand 102 of the core is defined as the length of one complete turn of the strand 102, measured parallel to the longitudinal axis X-X of the consumable 100. FIG. 1 illustrates the pitch P of a three strand 102 core 101. Increasing the pitch P will reduce the pressure drop of the consumable 100 and the residence time of air drawn through the consumable. In one example, the pitch P is between 0.2 and 1.5 times the diameter D of the helix formed by each strand 102.

[0077] The outer wrapper 108 may extend along the entire length of the core 101 or may extend only partially along the length of the core 101, as illustrated in FIG. 5. In the example of FIG. 5, the outer wrapper extends 108 from the mouth end 100′ of the consumable 100 over a portion of the length of the core 101. The mouth end 101′ of the consumable 100 is herein defined as the part of the consumable 100 placed between the lips of a user to allow the user to draw on the consumable 100. Therefore, the user's lips do not come into contact with the aerosol generating material 105 during use. Alternatively, the device 200 may be provided with a mouthpiece (not shown) which moveably encloses the area 201 for receiving the consumable 100. In such examples, when a consumable 100 is inserted into said area 201, the mouthpiece is moved to enclose said area 201 and can be placed between the lips of the user to allow the user to draw on the mouthpiece and inhale the aerosol generated during use of the device 200. Advantageously, the outer wrapper 108 may be omitted completely from consumables 100 configured for use with a device 200 comprising a mouthpiece. The consumable 100 may be sized to tightly abut a wall 207 of the area for receiving the consumable 100 so that airflow channels are instead formed between the core 101 of the consumable 100 and the wall 207 when the consumable is inserted into said area 201.

[0078] The outer wrapper 108 may be made of any suitable wrapping material, such as cigarette paper.

[0079] The example consumable 100 illustrated by FIG. 2e is the same as the example of FIG. 2d with the exception that the outer wrapper 108 is a laminate comprising first and second layers 110, 111. The first layer is an outer layer 110 and comprises paper, such as cigarette paper. The second layer 111 is an inner layer and comprises a material heatable by penetration with a varying magnetic field. The inner layer is herein referred to as a susceptor 111. Such example consumables 100 are configured for use with devices 200 comprising an aerosol generator 202 configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100, as explained further below. Therefore, when the consumable 100 is used with such a device 200, the susceptor 111 is heated by the varying magnetic field to heat the aerosol generating material 105 of the adjacent strands 102 and form an aerosol for inhalation by the user.

[0080] In examples described herein, the pitch circle diameter PCD of the strands 102 is between about 4 mm and 12 mm, or between about 5 mm and 11 mm, or between about 6 mm and 9 mm. In one example, the pitch circle diameter PCD of the strands 102 is about 7 mm, or about 8 mm, or about 9 mm, or about 10 mm.

[0081] By ‘pitch circle diameter PCD’ it is meant the diameter of a circle that passes through the center C of each strand 102. This is illustrated schematically in FIG. 7. By ‘center C of each strand’, it is meant a centerline C that follows the helical path of each strand 102. By selecting a pitch circle diameter PCD in accordance with the above examples, it can be ensured that the consumable provides an appropriate draw resistance during use and that the above discussed helical airflow pathway is sized to allow the generation of an appropriate quantity of aerosol therein when the consumable is heated.

[0082] The consumable 100 may comprise any number of additional components 90 for attachment to any of the cores 101 of twisted rope-like structure described above. Alternatively, the consumable 100 may consist of only the core 101 (for example, where the consumable 100 is configured for use with a device 200 comprising a mouthpiece). Where the consumable 100 comprises an additional component 90, the additional component 90 may be, for example, a filter component 91, as shown in the example consumable 100 of FIG. 3. Other components 90 may comprise cooling sections or other sections containing aerosol generating material, as is known in the field. The filter component 91 may be a paper filter component or a cellulose filter component. Preferably, any additional component 90 comprises an outside diameter substantially the same as the core 101 to which it is to be attached. Therefore, the additional component 90 may be attached by an overlapping layer of wrapping material, such as the outer wrapping material 108.

[0083] Including a filter component 91 advantageously allows for finer control of the closed pressure drop—or draw resistance—of the consumable 100. For example, the closed pressure drop may be controlled by setting the density of filter material in the filter component, or by increasing or decreasing the axial length of the filter component 91. The filter component 91 may be attached to either the mouth end 100′, as illustrated in FIG. 3, or to the distal end 100″.

[0084] In one example, the closed pressure drop of the consumable 100 is in the range of about 30 to 90 mmWg. In another example, the closed pressure drop of the consumable 100 is in the range of about 40 to 60 mmWg.

[0085] FIG. 6 schematically illustrates a method 60 of forming the consumables 100 of the examples discussed herein. The method comprises providing 61 at least two strands 102 of material, at least one of the strands comprising aerosol generating material 105; and forming 62 a twisted rope-like structure of the at least two strands of material 102. In some examples, the method further comprises wrapping 63 the twisted rope-like structure 101 in a wrapping material 108.

[0086] In some examples, providing 61 the at least two strands 102 of material comprises providing at least two strands of absorbent material 104 and doping 64 each strand of the absorbent material with aerosol generating material. The doping 64 may comprise doping 64 with a liquid aerosol generating material so that the absorbent material 104 absorbs the liquid aerosol generating material 105.

[0087] In some examples, providing 61 the at least two strands 102 comprises extruding 65 strands 102 of aerosol generating material 105 comprising an aerosol former, a binder, optionally a filler and optionally an active and / or a flavorant. In such examples, the aerosol generating material 105 may be a homogenized structure 106 of aerosol generating material 105.

[0088] In some examples, forming 62 the twisted rope-like structure comprises laying the strands 102 alongside each other in a bundle and twisting ends of the bundle to form helical strands 102 that extend around each other. It shall be appreciated that such twisted rope-like structures are distinct from other common rope like structures such as braided structures. A braided structure is distinct from a twisted structure in that the individual strands are woven in a braided structure, but not woven in a twisted structure. It would be further appreciated that a braided structure would not provide the helical flow path discussed above. Any such flow path would be broken up by the weave of such a braided structure.

[0089] FIG. 4 illustrates a system comprising the consumable 100 and a non-combustible aerosol provision device 200. The device comprises a power source 203, a controller 204 and a puff sensor 205. In use, a user inserts a consumable 100 into the area 201 for receiving the consumable and activates the aerosol generator 202 to generate an aerosol for inhalation. The user may then draw on the consumable 100 or, alternatively, on a mouthpiece (not shown) of the device 200 to inhale the aerosol. In the illustrated example, the consumable 100 and device 200 are configured so that mouth end 100′ of the consumable 100 protrudes from the area 201 for receiving the consumable 100 when fully inserted into the device 200. Therefore, the consumable 100 is available for placing between the lips of the user while the user holds the device 200.

[0090] The puff sensor 205 is configured to detect when a user is drawing on the consumable 100 within the device 200 and to send a signal to the controller 204 to activate the aerosol generator 202. Therefore, aerosol is generated concurrently with the user inhaling on the consumable 100. Alternatively, the device 200 may be provided with a user interface—such as a button (not shown)—that the user may interact with to cause activation of the aerosol generator 202.

[0091] The area 201 for receiving the consumable 100 is provided with an inlet (not shown) to allow air into the area 201 for passing through the consumable 100 when a user inhales on the mouth end 100′ of the consumable 100. Therefore, a flow of air is directed through the consumable 100 when a user draws on the consumable 100. More particularly, the flow of air is directed along the airflow pathway of the consumable 100. The flow of air entrains the aerosol generated by the aerosol generating material 105 of the consumable 100 when heated by the aerosol generator 202.

[0092] The aerosol generator 202 comprises any suitable means for heating the aerosol generating material 105 of a consumable received in said area 201 of the device 200. Power for the aerosol generator 202 is provided by the power source 203, which in the illustrated example is an electrical power source 203, such as a battery 203.

[0093] In one example, the aerosol generator 202 comprises a magnetic field generator configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100. The varying magnetic field heats a susceptor 107, 111 that is placed within the area 201 for the receiving the consumable 100 by magnetic hysteresis. This example may be used, therefore, with a consumable 100 comprising a material heatable by a varying magnetic field, as described above. Therefore, when such a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a varying magnetic field penetrates said material of the consumable 100 and causes heating of aerosol generating material 105 in thermal contact with said material, generating an aerosol for inhalation by a user.

[0094] In another example, the aerosol generator 202 comprises a susceptor in thermal contact with the area 201 for receiving the consumable; and a magnetic field generator for generating a varying magnetic field that penetrates the susceptor. The varying magnetic field heats the susceptor by magnetic hysteresis. The susceptor in turn heats the area 201 for receiving the consumable. Therefore, when a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a varying magnetic field penetrates the susceptor and causes heating of area 201 in which the consumable 100 is received. The heat is transferred to the aerosol generating material 105 of the consumable 100, generating an aerosol for inhalation by the user. In such embodiments, the susceptor may be the wall 207 of the area 201 for receiving the consumable 100 and the consumable 100 may be configured for direct contact with the wall 207 for efficient heat transfer.

[0095] In another example, the aerosol generator 202 comprises a material heatable by electrical conduction, the material being provided in thermal contact with the area 201 for receiving the consumable 100. Therefore, when a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a current is passed through the material to heat area 201 in which the consumable 100 is received. The heat is transferred to the aerosol generating material 105 of the consumable 100, generating an aerosol for inhalation by the user. In such embodiments, the material may be the wall 207 of the area 201 for receiving the consumable 100 and the consumable 100 may be configured for direct contact with the wall 207 for efficient heat transfer.

[0048] Aerosol-generating material is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, be in the form of a solid, liquid or semi-solid (such as a gel) which may or may not contain an active substance and / or flavorants.

[0049] The aerosol-generating material may comprise one or more active substances and / or flavors, one or more aerosol-former materials, and optionally one or more other functional material.

[0050] The aerosol-generating material may comprise a binder, such as a gelling agent, and an aerosol former. Optionally, a substance to be delivered and / or filler may also be present. Optionally, a solvent, such as water, is also present and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. In some embodiments, the aerosol-generating material is substantially free from botanical material. In particular, in some embodiments, the aerosol-generating material is substantially tobacco free.

[0051] The aerosol-generating material may comprise or be in the form of an aerosol-generating film. The aerosol-generating film may comprise a binder, such as a gelling agent, and an aerosol former. Optionally, a substance to be delivered and / or filler may also be present. The aerosol-generating film may be substantially free from botanical material. In particular, in some embodiments, the aerosol-generating material is substantially tobacco free.

[0052] The aerosol-generating film may have a thickness of about 0.015 mm to about 1 mm. For example, the thickness may be in the range of about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm.

[0053] The aerosol-generating film may be continuous. For example, the film may comprise or be a continuous sheet of material. The sheet may be in the form of a wrapper, it may be gathered to form a gathered sheet or it may be shredded to form a shredded sheet. The shredded sheet may comprise one or more strands or strips of aerosol-generating material.

[0054] The aerosol-generating film may be discontinuous. For example, the aerosol-generating film may comprise one or more discrete portions or regions of aerosol-generating material, such as dots, stripes or lines, which may be supported on a support. In such embodiments, the support may be planar or non-planar.

[0055] The aerosol-generating film may be formed by combining a binder, such as a gelling agent, with a solvent, such as water, an aerosol-former and one or more other components, such as one or more substances to be delivered, to form a slurry and then heating the slurry to volatilize at least some of the solvent to form the aerosol-generating film.

[0056] The slurry may be heated to remove at least about 60 wt %, 70 wt %, 80 wt %, 85 wt % or 90 wt % of the solvent.

[0057] The aerosol-generating material may comprise an aerosol former, a binder, optionally a filler and optionally an active and / or a flavorant.

[0058] The aerosol-former material may comprise one or more constituents capable of forming an aerosol. In some embodiments, the aerosol-former material may comprise one or more of glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0059] The one or more other functional materials may comprise one or more of a pH regulators, coloring agents, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0060] The aerosol generating material may be present on or in a support, the support forming a substrate. The support may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or either side of the material.

[0061] A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

[0062] An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavor, acidity or another characteristic of the aerosol. The aerosol-modifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent

[0063] The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavorant, a colorant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0064] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol.

[0065] FIG. 1 illustrates a consumable 100 for use with a non-combustible aerosol provision device, such as the non-combustible aerosol provision device 200 schematically illustrated by FIG. 4. The consumable 100 comprises a core 101 comprising a twisted rope-like structure of at least two strands 102 of material. At least one of the strands 102 of material comprises aerosol generating material 105.

[0066] The non-combustible aerosol provision device 200 comprises an area 201 for receiving the consumable 100 and an aerosol generator 202. The aerosol generator 202 is configured to heat the aerosol generating material 105 of the consumable 100 when it is received in the area 201 to generate an aerosol for inhalation by a user, as will be explained further below.

[0067] FIGS. 2a to 2e show example consumables 100 in cross section. Each cross section is projected onto a plane that bisects the consumable 100 perpendicular to its longitudinal axis. In each example, the core 101 of each consumable 100 comprises three strands 102, though it will be appreciated any of the examples may comprise only two strands 102 or more than two strands 102, such as four or five strands 102. It will also be appreciated that, while the illustrated strands 102 comprise a circular cross section, other cross sectional shapes may be used as long as the resulting strands can be twisted together to form a rope-like structure. In some examples described herein, the diameter of each strand 102 is between 0.1 mm and 5 mm, or between 1 mm and 3 mm. In one example, the diameter of each strand 102 is about 2 mm.

[0068] In the example of FIG. 2a, each strand is formed from an absorbent material 104. The absorbent material 104 is provided with an aerosol generating material 105. For example, the aerosol generating material 105 may be provided as an additive to the absorbent material 104. In some examples, the absorbent material 104 may be doped with the aerosol generating material 105 in a liquid form so that the aerosol generating material 105 is absorbed by the absorbent material 104. The absorbent material 104 may be any material for suitable for absorbing aerosol generating materials 105 described herein. The absorbent material 104 may be a fibrous material and may be plant based. In one example the absorbent material 104 is a crimped and gathered paper. The aerosol generating material 105 may comprise an aerosol former material, as defined above. Therefore, when the consumable 100 is heated in use, the aerosol former material evaporates to form an aerosol for inhalation by a user. The aerosol generating material 105 may also comprise one or more active substances, one or more flavors and / or one or more other functional materials, as defined above. In one example, the absorbent material 104 is provided with an aerosol generating material 105 that comprises an aerosol former material comprising glycerol, a flavor and an active substance comprising nicotine. Optionally, the absorbent material 104 is a reconstituted tobacco material that is formed as an absorbent tobacco paper. Therefore, the absorbent material 104 additionally provides flavor to the aerosol former material when the consumable is heated during use.

[0069] Where strands 102 of reconstituted tobacco material are used, the strands 102 may be provided in strips of reconstituted tobacco material. The reconstituted tobacco strands can be longitudinal strips. The reconstituted tobacco material can be, for example, band cast reconstituted tobacco material or paper reconstituted tobacco material. In some embodiments, the strands are provided as flat strips of reconstituted tobacco. The strips may have a width of between 0.25 mm and 2 mm; a thickness of 30 to 1000 μm, or 30 to 300 μm; and a density in the range of about 20 to 250 grams per square meter. The strips may have a ratio of the width to the thickness of between 0.25 and 70, or between 1 and 10.

[0070] To form the core 101, the strips are arranged in parallel and collected in a bundle before being twisted into a rope like structure in accordance with the method 60 described below with reference to FIG. 6. Any number of strands may be used, but in some examples, between 100 and 300 number of strands may be used to form the core. In some examples, the core may have a density of between 0.1 g / cm3 and 0.9g / cm3.

[0071] An advantage of twisting strips of reconstituted tobacco material into a rope like structure is that the strips become interlocked, making them less easily displaced. This is particularly beneficial when the consumable is used with a non-combustible aerosol provision device 200 comprising a pin or blade-like heater that extends into the area 201 for receiving the consumable 100. A pin or blade-like heater is configured to penetrate the consumable 100 along its axis to heat the aerosol generating material 105. It has been found that consumables comprising strands of reconstituted tobacco material that are not formed into a twisted rope like structure tend to be displaced by such heaters, leaving debris with the area 201 for receiving the consumable. During longer term use of the device, this debris can accumulate to the detriment of heater efficiency and hygiene.

[0072] In another example illustrated by FIG. 2b, each strand comprises a homogenized structure 106 of aerosol generating material 105, wherein the aerosol generating material 105 comprises an aerosol former, a binder, optionally a filler, and optionally an active and / or a flavorant. In the illustrated example, each strand 102 is a monolithic solid. That is to say, each strand is cast as single piece. For example, each strand 102 may be an extruded section of the aerosol generating material 105. When the consumable 100 is heated in use, volatile constituents of the aerosol generating material 105 evaporate to form an aerosol for inhalation by a user.

[0073] The example consumable 100 illustrated by FIG. 2c is the same as the example of FIG. 2b with the exception that each strand 102 further comprises a material 107 heatable by penetration with a varying magnetic field, herein referred to as a susceptor 107. In the illustrated example, a susceptor 107 is embedded in each strand 102 of the consumable 100. Such example consumables 100 are configured for use with a device 200 comprising an aerosol generator 202 configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100, as explained further below. Therefore, when the consumable 100 is used with such a device 200, the susceptor 107 of each strand 102 is heated by the varying magnetic field to heat the aerosol generating material 105 and form an aerosol for inhalation by the user. In the illustrated example, the susceptor 107 of each strand 102 comprises a twisted rope-like structure. However, it will be appreciated that the susceptors 207 may take any form suitable for their integration into the strands 102. Therefore, the susceptors 207 are preferably formed of a resiliently flexible material that allows them to follow the helical path of the strands 102 in which they are embedded. In the illustrated example, each susceptor 107 is embedded substantially centrally within a strand 102. Such example consumables 100 may be formed by extruding a strand 102 of aerosol generating material 105 around a continuous length of susceptor 107. Each strand 102 is then cut to length and twisted about at least one other such strand 102 to form the rope-like structure of the core 101, as will be explained further below.

[0074] In another unillustrated example, each strand 102 comprises a susceptor 107 embedded in a strand 102 formed from a material other than a homogenized structure 106 of aerosol generating material 105. It will be appreciated that a susceptor 207 may be embedded in any of the strands 102 described herein. For example, a susceptor 207 may be embedded in strands 102 of absorbent material, such as the strands 102 described in connection with FIG. 2a. Such example strands 102 may be formed by gathering absorbent material 104 around a continuous length of susceptor 107. Each resulting strand 102 is then cut to length and twisted about at least one other such strand 102 to form the rope-like structure of the core 101, as will be explained further below with reference to the method of FIG. 6.

[0075] The example consumable illustrated by FIG. 2d further comprises an outer wrapping material 108 that circumscribes the core 101. The illustrated strands 102 are representative of any of the strands 102 described above, including strands 102 of absorbent material 104 and strands of comprising a homogenized structure 106 of aerosol generating material 105. In such examples the consumable 100 is provided with a smooth, generally cylindrical appearance. The outer wrapper 108 forms an outer surface of the consumable 100. Therefore, wrapping the core 101 in an outer wrapper 108 prevents the user from having to handle the core 101 directly. This may be beneficial to stop the user getting any of the aerosol generating material 105 on them where they touch the consumable 100. A further advantage of the outer wrapper108 is that air flow channels 109 are formed between the outer wrapper 108 and the core 101. The air flow channels 109 follow the helical groove formed between strands 102 of the rope-like structure. The air flow channels 209 form a helical air flow pathway that extends from a distal end 100″ of the consumable to a mouth end 100′. On account of their helical shape, the length of the helical air flow pathway formed by the air flow channels 209 is greater than if the air flow pathway were straight. That is to say, the length of the helical air flow pathway is greater than a straight air flow pathway that extends over the same axial length of the consumable 100. Therefore, the residence time of air drawn through the consumable 100 is greater than if the air flow pathway were straight. This allows more of the constituent parts of the aerosol formed during use to be entrained into the air drawn along the air flow pathway. Another effect of the helical airflow pathway is that the pressure drop across the consumable is greater than if the airflow pathway were straight.

[0076] It will be appreciated that the length of the airflow pathway can be affected by the pitch P of the helix formed by each strand 102 of the core 101. The pitch P of the helix formed by each strand 102 of the core is defined as the length of one complete turn of the strand 102, measured parallel to the longitudinal axis X-X of the consumable 100. FIG. 1 illustrates the pitch P of a three strand 102 core 101. Increasing the pitch P will reduce the pressure drop of the consumable 100 and the residence time of air drawn through the consumable. In one example, the pitch P is between 0.2 and 1.5 times the diameter D of the helix formed by each strand 102.

[0077] The outer wrapper 108 may extend along the entire length of the core 101 or may extend only partially along the length of the core 101, as illustrated in FIG. 5. In the example of FIG. 5, the outer wrapper extends 108 from the mouth end 100′ of the consumable 100 over a portion of the length of the core 101. The mouth end 101′ of the consumable 100 is herein defined as the part of the consumable 100 placed between the lips of a user to allow the user to draw on the consumable 100. Therefore, the user's lips do not come into contact with the aerosol generating material 105 during use. Alternatively, the device 200 may be provided with a mouthpiece (not shown) which moveably encloses the area 201 for receiving the consumable 100. In such examples, when a consumable 100 is inserted into said area 201, the mouthpiece is moved to enclose said area 201 and can be placed between the lips of the user to allow the user to draw on the mouthpiece and inhale the aerosol generated during use of the device 200. Advantageously, the outer wrapper 108 may be omitted completely from consumables 100 configured for use with a device 200 comprising a mouthpiece. The consumable 100 may be sized to tightly abut a wall 207 of the area for receiving the consumable 100 so that airflow channels are instead formed between the core 101 of the consumable 100 and the wall 207 when the consumable is inserted into said area 201.

[0078] The outer wrapper 108 may be made of any suitable wrapping material, such as cigarette paper.

[0079] The example consumable 100 illustrated by FIG. 2e is the same as the example of FIG. 2d with the exception that the outer wrapper 108 is a laminate comprising first and second layers 110, 111. The first layer is an outer layer 110 and comprises paper, such as cigarette paper. The second layer 111 is an inner layer and comprises a material heatable by penetration with a varying magnetic field. The inner layer is herein referred to as a susceptor 111. Such example consumables 100 are configured for use with devices 200 comprising an aerosol generator 202 configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100, as explained further below. Therefore, when the consumable 100 is used with such a device 200, the susceptor 111 is heated by the varying magnetic field to heat the aerosol generating material 105 of the adjacent strands 102 and form an aerosol for inhalation by the user.

[0080] In examples described herein, the pitch circle diameter PCD of the strands 102 is between about 4 mm and 12 mm, or between about 5 mm and 11 mm, or between about 6 mm and 9 mm. In one example, the pitch circle diameter PCD of the strands 102 is about 7 mm, or about 8 mm, or about 9 mm, or about 10 mm.

[0081] By ‘pitch circle diameter PCD’ it is meant the diameter of a circle that passes through the center C of each strand 102. This is illustrated schematically in FIG. 7. By ‘center C of each strand’, it is meant a centerline C that follows the helical path of each strand 102. By selecting a pitch circle diameter PCD in accordance with the above examples, it can be ensured that the consumable provides an appropriate draw resistance during use and that the above discussed helical airflow pathway is sized to allow the generation of an appropriate quantity of aerosol therein when the consumable is heated.

[0082] The consumable 100 may comprise any number of additional components 90 for attachment to any of the cores 101 of twisted rope-like structure described above. Alternatively, the consumable 100 may consist of only the core 101 (for example, where the consumable 100 is configured for use with a device 200 comprising a mouthpiece). Where the consumable 100 comprises an additional component 90, the additional component 90 may be, for example, a filter component 91, as shown in the example consumable 100 of FIG. 3. Other components 90 may comprise cooling sections or other sections containing aerosol generating material, as is known in the field. The filter component 91 may be a paper filter component or a cellulose filter component. Preferably, any additional component 90 comprises an outside diameter substantially the same as the core 101 to which it is to be attached. Therefore, the additional component 90 may be attached by an overlapping layer of wrapping material, such as the outer wrapping material 108.

[0083] Including a filter component 91 advantageously allows for finer control of the closed pressure drop—or draw resistance—of the consumable 100. For example, the closed pressure drop may be controlled by setting the density of filter material in the filter component, or by increasing or decreasing the axial length of the filter component 91. The filter component 91 may be attached to either the mouth end 100′, as illustrated in FIG. 3, or to the distal end 100″.

[0084] In one example, the closed pressure drop of the consumable 100 is in the range of about 30 to 90 mmWg. In another example, the closed pressure drop of the consumable 100 is in the range of about 40 to 60 mmWg.

[0085] FIG. 6 schematically illustrates a method 60 of forming the consumables 100 of the examples discussed herein. The method comprises providing 61 at least two strands 102 of material, at least one of the strands comprising aerosol generating material 105; and forming 62 a twisted rope-like structure of the at least two strands of material 102. In some examples, the method further comprises wrapping 63 the twisted rope-like structure 101 in a wrapping material 108.

[0086] In some examples, providing 61 the at least two strands 102 of material comprises providing at least two strands of absorbent material 104 and doping 64 each strand of the absorbent material with aerosol generating material. The doping 64 may comprise doping 64 with a liquid aerosol generating material so that the absorbent material 104 absorbs the liquid aerosol generating material 105.

[0087] In some examples, providing 61 the at least two strands 102 comprises extruding 65 strands 102 of aerosol generating material 105 comprising an aerosol former, a binder, optionally a filler and optionally an active and / or a flavorant. In such examples, the aerosol generating material 105 may be a homogenized structure 106 of aerosol generating material 105.

[0088] In some examples, forming 62 the twisted rope-like structure comprises laying the strands 102 alongside each other in a bundle and twisting ends of the bundle to form helical strands 102 that extend around each other. It shall be appreciated that such twisted rope-like structures are distinct from other common rope like structures such as braided structures. A braided structure is distinct from a twisted structure in that the individual strands are woven in a braided structure, but not woven in a twisted structure. It would be further appreciated that a braided structure would not provide the helical flow path discussed above. Any such flow path would be broken up by the weave of such a braided structure.

[0089] FIG. 4 illustrates a system comprising the consumable 100 and a non-combustible aerosol provision device 200. The device comprises a power source 203, a controller 204 and a puff sensor 205. In use, a user inserts a consumable 100 into the area 201 for receiving the consumable and activates the aerosol generator 202 to generate an aerosol for inhalation. The user may then draw on the consumable 100 or, alternatively, on a mouthpiece (not shown) of the device 200 to inhale the aerosol. In the illustrated example, the consumable 100 and device 200 are configured so that mouth end 100′ of the consumable 100 protrudes from the area 201 for receiving the consumable 100 when fully inserted into the device 200. Therefore, the consumable 100 is available for placing between the lips of the user while the user holds the device 200.

[0090] The puff sensor 205 is configured to detect when a user is drawing on the consumable 100 within the device 200 and to send a signal to the controller 204 to activate the aerosol generator 202. Therefore, aerosol is generated concurrently with the user inhaling on the consumable 100. Alternatively, the device 200 may be provided with a user interface—such as a button (not shown)—that the user may interact with to cause activation of the aerosol generator 202.

[0091] The area 201 for receiving the consumable 100 is provided with an inlet (not shown) to allow air into the area 201 for passing through the consumable 100 when a user inhales on the mouth end 100′ of the consumable 100. Therefore, a flow of air is directed through the consumable 100 when a user draws on the consumable 100. More particularly, the flow of air is directed along the airflow pathway of the consumable 100. The flow of air entrains the aerosol generated by the aerosol generating material 105 of the consumable 100 when heated by the aerosol generator 202.

[0092] The aerosol generator 202 comprises any suitable means for heating the aerosol generating material 105 of a consumable received in said area 201 of the device 200. Power for the aerosol generator 202 is provided by the power source 203, which in the illustrated example is an electrical power source 203, such as a battery 203.

[0093] In one example, the aerosol generator 202 comprises a magnetic field generator configured to generate a varying magnetic field that penetrates the area 201 for receiving the consumable 100. The varying magnetic field heats a susceptor 107, 111 that is placed within the area 201 for the receiving the consumable 100 by magnetic hysteresis. This example may be used, therefore, with a consumable 100 comprising a material heatable by a varying magnetic field, as described above. Therefore, when such a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a varying magnetic field penetrates said material of the consumable 100 and causes heating of aerosol generating material 105 in thermal contact with said material, generating an aerosol for inhalation by a user.

[0094] In another example, the aerosol generator 202 comprises a susceptor in thermal contact with the area 201 for receiving the consumable; and a magnetic field generator for generating a varying magnetic field that penetrates the susceptor. The varying magnetic field heats the susceptor by magnetic hysteresis. The susceptor in turn heats the area 201 for receiving the consumable. Therefore, when a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a varying magnetic field penetrates the susceptor and causes heating of area 201 in which the consumable 100 is received. The heat is transferred to the aerosol generating material 105 of the consumable 100, generating an aerosol for inhalation by the user. In such embodiments, the susceptor may be the wall 207 of the area 201 for receiving the consumable 100 and the consumable 100 may be configured for direct contact with the wall 207 for efficient heat transfer.

[0095] In another example, the aerosol generator 202 comprises a material heatable by electrical conduction, the material being provided in thermal contact with the area 201 for receiving the consumable 100. Therefore, when a consumable 100 is placed within the device 200 and the aerosol generator 202 is activated, a current is passed through the material to heat area 201 in which the consumable 100 is received. The heat is transferred to the aerosol generating material 105 of the consumable 100, generating an aerosol for inhalation by the user. In such embodiments, the material may be the wall 207 of the area 201 for receiving the consumable 100 and the consumable 100 may be configured for direct contact with the wall 207 for efficient heat transfer.
