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 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 flavourants.

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

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. The aerosol-generating material may comprise or be in the form of an aerosolgenerating 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 maybe substantially free from botanical material. In particular, in some embodiments, the aerosolgenerating material is substantially tobacco free.

The aerosol-generating film may have a thickness of about 0.015 mm to about 1 mm. The aerosol-generating film may be up to 0.5mm thick, preferably 0.05mm to 0.5mm microns thick. 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.

Aerosol generating films described herein may comprise an aerosol former, a binder, optionally a filler and optionally an active and/or a flavourant.

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 maybe gathered to form a gathered sheet or it maybe shredded to form a shredded sheet. The shredded sheet may comprise one or more strands or strips of aerosol-generating material. The aerosol-generating film may be discontinuous. For example, the aerosolgenerating film may comprise one or more discrete portions or regions of aerosolgenerating 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.

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 volatilise at least some of the solvent to form the aerosol-generating film. The slurry may be heated to remove at least about 60 wt%, 70 wt%, 80 wt%, 85 wt% or 90 wt% of the solvent.

The aerosol-generating material may comprise or be an “amorphous solid”. In some embodiments, the aerosol-generating material comprises an aerosol- generating film that is an amorphous solid. The amorphous solid may be a “monolithic solid”. The amorphous solid may be substantially non-fibrous. In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the amorphous solid may, for example, comprise from about 50wt%, 6owt% or 70wt% of amorphous solid, to about 90wt%, 95wt% or ioowt% of amorphous solid.

The amorphous solid may be substantially free from botanical material. The amorphous solid may be substantially tobacco free. 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.

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

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. 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.

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, flavour, 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 aerosolmodifying agent

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 flavourant, a colourant, 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.

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.

Fig. 1 illustrates a consumable too for use with a non-combustible aerosol provision device, such as the non-combustible aerosol provision device 200 schematically illustrated by Fig. 15. The non-combustible aerosol provision device 200 comprises an area 201 for receiving the consumable too and an aerosol generator 202. The aerosol generator 202 is configured to heat aerosol generating material of the consumable too when it is received in the area 201 to generate an aerosol for inhalation by a user, as will be explained further below.

The consumable too is elongate and comprises a mouth end 101 and a distal end 102 opposite the mouth end 101. The distal end 102 is defined as a portion 102 of the consumable too configured for insertion into the area 201 of the aerosol provision device 200. In some examples described herein, the distal end 102 is shaped for insertion into said area 201 in at least one predetermined orientation about a longitudinal axis X-X of the consumable too. By ‘predetermined orientation’ it is meant at least one rotational position about the longitudinal axis X-X of the consumable too relative to the device 200. Additionally or alternatively, in other examples described herein, the mouth end

101 is shaped to prevent insertion into the area 201 for receiving the consumable. In other words, the cross sectional profile of the mouth end 101 is different to the cross sectional profile of the distal end 102 in size, shape or both. An example of this is illustrated by Figs. 1 and 2. Fig. 2 is an end on view of the consumable of Fig. 1. In this example, it can be seen that mouth end 101 comprises an oval cross sectional profile, while the distal end 102 comprises a circular cross sectional profile. The width W of the oval cross sectional profile of the mouth end 101 is greater than the diameter D of circular cross sectional profile of the distal end 102. Therefore, the consumable too is configured for use with a device 200 having an area 201 for receiving the consumable too in which the cross sectional profile of said area 201 is substantially the same in size and shape as the cross sectional profile of the distal end 102 of the consumable too.

This means that the distal end 102 of the consumable too can be inserted into said area 201, but the mouth end 101 cannot. An advantage of this is that a user cannot inadvertently insert the mouth end 101 into said area 201.

A cross section taken through Fig. 1 is shown in Fig. 3. The cross section is projected onto a plane that bisects the consumable too perpendicular to its longitudinal axis X-X. The cross section is taken through the distal end 102 of the consumable too. It can be seen that the distal end 102 comprises a rod 103 formed of a cylindrical support 104 that surrounds an air gap 106. Aerosol generating material 105 is provided as a film on an inner surface of the support 104 such that the aerosol generating material 105 forms an inner surface of the rod 103. The aerosol generating material 105 may be an amorphous solid comprising a binder, gelling agent and an aerosol former, as described above. In use, when the consumable too and device 200 are combined and the aerosol generating material 105 is heated by the aerosol generator 202, the aerosol generating material 105 forms an aerosol in the air gap 106 for inhalation by a user. In the example illustrated by Fig. 3, the support 104 is a laminate comprising a first and second layers 107, 108. The second layer 108 is disposed in between the first layer 107 and the aerosol generating material 105 and comprises a material heatable by penetration with a varying magnetic field. Said material heatable by penetration with a varying magnetic field is herein referred to as a susceptor 108. Such consumables too 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 too, as explained further below. However, it will be appreciated that the susceptor 108 is optional and that, in some examples, the support 104 comprises only a single layer and aerosol generating material 105 provided directly on said single layer. In addition to the optional susceptor 108, the support 104 may comprise a card or paper based material that is spirally wound into the hollow tube 103 during manufacturing of the consumable too in the usual way, for example, about a mandrel. The aerosol generating material 105 maybe added to the support prior to being wound into the rod 103, or after.

The mouth end 101 of the example of Fig. 1 maybe a moulded fibrous material. In some such examples, the mouth end 101 may be cellulose acetate. Such a mouth end 101 is air permeable to allow a user to place their lips around the mouth end 101 and draw air through the distal end 102 in use. Alternatively or additionally, the mouth end 101 may comprise an aperture (not shown) configured to allow air to pass through the mouth end 101 in use. The mouth end 101 maybe attached to the distal end 102 by a wrapping material that overlaps the mouth end 101 and distal end 102 to hold the two together. The mouth end 101 may comprise an end with circular profile, opposite the end with the oval profile. This enables the wrapping material to extend over at least a portion of the mouth end 101 and be flush with the distal end 102. In one example, the mouth end 101 is formed from a cylindrical plug of fibrous material with the same external diameter as the distal end 102 to allow the wrapping material to overlap at least a portion of the mouth end 101 and the distal end 102 to attach the two 101, 102 together. The oval shape may then be provided by compressing the mouth end 101 opposite to where it is attached to the distal end 102. Plasticizer or another hardening solution can then be applied to the compressed section of the mouth end 101 so that it retains the oval shape. Another example consumable too is illustrated by Fig. 4. The consumable too of Fig. 4 may be the same as the consumable too of Fig. 1 with the exception that the consumable of Fig. 4 comprises a differently shaped mouth end 101 to the mouth end 101 of the example of Fig. 1. In the example of Fig. 4, the mouth end 101 is the same shape as the distal end 102, but has a greater diameter. Therefore, the consumable too is configured for use with a device 200 having an area 201 for receiving the consumable too in which the cross sectional profile of said area 201 is substantially the same in diameter as the cross sectional profile of the distal end 102 of the consumable too. As in the example of Fig. 1, this means that the distal end 102 of the consumable too of Fig. 4 can be inserted into said area 201, but the mouth end 101 cannot. A cross section of the mouth end 101 of the example of Fig. 4 is shown in Fig. 5. The cross section is projected onto a plane that bisects the consumable too perpendicular to its longitudinal axis X-X. The mouth end 101 comprises an outer sheath 109. The outer sheath 109 is a cylindrical component that may be push fit onto the distal end 102 of the consumable to form the mouth end 101. The outer sheath 109 may be formed of a fibrous material such as card, paper or cellulosed acetate.

It will be appreciated that, while the examples of Figs. 1 and 4 comprise distal ends 102 with an air gap 106, in other examples the distal ends 102 may be filled with aerosol generating material. For example, the distal ends 102 may comprise cut or crimped reconstituted tobacco paper that fills the rod 103. In particular, such distal ends 102 may be formed by gathering cut or crimped aerosol generating material 105 on a garniture and thereafter wrapping the aerosol generating material 105 with the support 104 in the conventional way. The support 104 may be a cigarette paper or similar. Fig. 6 shows an example consumable too comprising a distal end 102 shaped for insertion into the device 200 in at least one predetermined orientation about a longitudinal axis X-X of the consumable too. The distal end 102 of the consumable too comprises an outer wrapper 110 that is wrapped about the distal end 102 so that edges 114 of the outer wrapper form a fin seal 111. By ‘fin seal 111’ it is meant that edge- adjacent portions 112 of the outer wrapper 110 abut to upstand radially away from the outer surface 113 of the outer wrapper 110. While not illustrated, the example consumable of Fig. 6 may further comprise an oval shaped mouth end 101 attached to the distal end 102 by the outer wrapper 110 in the manner described above. Therefore, the outer wrapper 110 forming the fin seal 111 also serves as the wrapping material for attaching the mouth end 101.

Fig. 9 shows an end view of an example device 200 configured to accept the consumable of Fig. 6 in said predetermined orientation. In particular, the area 201 for receiving the consumable is defined by a wall 207 with a cross sectional profile substantially the same in size and shape as the cross sectional profile of the distal end

102 of the consumable too of Fig. 6. Due to the fin seal 111, the cross sectional profile of the distal end 102 of the consumable too has a rotational symmetry of order 1. This means that there is only one predetermined orientation of the consumable too relative to the device 200 in which the distal end 102 of the consumable is insertable into said area 201.

A cross section taken through Fig. 6 is shown in Fig. 10. The cross section is projected onto a plane that bisects the distal end 102 of consumable too perpendicular to its longitudinal axis X-X. It can be seen that, in the present example, the aerosol generating material 105 comprises a crimped and gathered tobacco paper 105 that fills the outer wrapper 110. However, it will be appreciated that an outer wrapper 110 comprising a fin seal 111 maybe provided in other examples, such as around the rod 103 of the example of Fig. 3. In the example of Fig. 6, the distal end 102 further comprises a material heatable by penetration with a varying magnetic field. Said material is herein referred to as a susceptor 115. The susceptor 115 is flat strip that extends along the longitudinal axis X-X of the consumable. Such consumables too 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 too. The example consumable too of Fig. 6 enables the design of a more efficient device 200 and consumable too system. As the consumable too can only be inserted into the device 200 in one predetermined orientation, it is possible to design the consumable too so that the susceptor 115 orientation relative to the aerosol generator 202 is known. In particular, by orienting the susceptor 115 within the consumable too in a predetermined orientation relative to the fin seal 111 it is possible to determine the susceptor’s 115 orientation relative to the device 200 and, therefore, relative to the aerosol generator 202. This means that an aerosol generator 202 can be used that generates only the magnetic field required for penetrating the susceptor 115 in the single predetermined orientation. In turn, the aerosol generator 202 may generate a smaller magnetic field than would otherwise be required and, therefore, the aerosol generator 202 may consume less power for a given level of heating. It follows that such devices 200 will consume less electrical energy during heating of the consumable too. It will be appreciated that this effect can be extended to other example consumables. What is important is that the distal end 102 of the consumable too comprises rotational symmetry of order 1 or order 2 and the susceptor 115 comprises a flat strip in a predetermined orientation relative to the distal end 102. Example consumables falling within this description are illustrated by Figs. 7 and 8.

Fig. 7 shows another example consumable too comprising a distal end 102 shaped for insertion into the device 200 in single predetermined orientation relative to the device

200. The distal end 102 of the consumable too comprises an outer wrapper 110 that is wrapped about the distal end 102 so that edges 114 of the outer wrapper 110 form a lap seam 116. By ‘lap seam 116’ it is meant that the edges 114 of the outer wrapper 110 overlap. This creates a lip 117 in the outer surface 113 of the distal end 102 equivalent to the thickness of the outer wrapper 110. While not illustrated, the example consumable of Fig. 7 may again further comprise an oval shaped mouth end 101 attached to the distal end 102 by the outer wrapper 110 in the manner described above. Therefore, the outer wrapper 110 forming the lap seam also serves as the wrapping material for attaching the mouth end 101.

The outer wrapper 110 of the example of Fig. 7 is required to have a thickness sufficient to enable the lip 117 to serve as a guide for orientation of the consumable. It will be appreciated that the thickness of the outer wrapper 110 equates to the height of the lip 117. In one example, the outer wrapper 110 comprises a thickness of greater than 0.7mm. In another example, the thickness of the outer wrapper is greater than 0.9mm.

In another example, the thickness of the outer wrapper is between 0.7mm and 1.2mm.

Fig. 11 shows an end view of an example device 200 configured to accept the consumable of Fig. 7 in said predetermined orientation. In particular, the area 201 for receiving the consumable is defined by a wall 207 with a cross sectional profile substantially the same in size and shape as the cross sectional profile of the distal end 102 of the consumable 100 of Fig. 7. Due to the lip 117, the cross sectional profile of the distal end 102 of the consumable 100 has a rotational symmetry of order 1. This means that there is only one predetermined orientation of the consumable too relative to the device 200 in which the distal end 102 of the consumable is insertable into said area

201.

A cross section taken through Fig. 7 is shown in Fig. 12. The cross section is projected onto a plane that bisects the distal end 102 of consumable too perpendicular to its longitudinal axis X-X. It can be seen that, in the present example, as in the example of

Fig. 6, the aerosol generating material 105 comprises a crimped and gathered tobacco paper 105 that fills the outer wrapper 110. However, it will be appreciated that an outer wrapper 110 comprising a lap seam maybe provided in other examples, such as around the rod 103 of the example of Fig. 3. The distal end 102 further comprises a susceptor 115 in a predetermined orientation relative to the lip 117 such that the consumable too of Fig. 7 affords the same advantages in system design as discussed above. In particular, the system may use an aerosol generator 202 that generates a smaller magnetic field than would otherwise be required if the susceptor were not in said predetermined orientation and, therefore, the aerosol generator 202 may consume less power for a given level of heating.

Fig. 8 shows another example consumable too comprising a distal end 102 shaped for insertion into the device 200 in single predetermined orientation relative to the device 200. The distal end of the consumable too comprises an oval cross section. Therefore, the cross section of the distal end 102 comprises rotational symmetry of order two.

Fig. 13 shows an end view of an example device 200 configured to accept the consumable of Fig. 8 in said predetermined orientation. In particular, the area 201 for receiving the consumable is defined by a wall 207 with a cross sectional profile substantially the same in size and shape as the cross sectional profile of the distal end 102 of the consumable too of Fig. 8. As the cross sectional profile of the distal end 102 of the consumable too has a rotational symmetry of order two, there are two predetermined orientations of the consumable too relative to the device 200 in which the distal end 102 of the consumable is insertable into said area 201. A cross section taken through Fig. 8 is shown in Fig. 13. The cross section is projected onto a plane that bisects the distal end 102 of consumable too perpendicular to its longitudinal axis X-X. It can be seen that, in the present example, as in the examples of Figs. 6 and 7, the aerosol generating material 105 comprises a crimped and gathered tobacco paper 105. However, it will be appreciated that consumable too may instead comprise a hollow oval section comprising a film of aerosol generating material coated on its inner surface. In such examples, the consumable too would instead comprise an air gap in which aerosol is generated when the aerosol generating material is heated in use. In the illustrated example, the distal end 102 further comprises a susceptor 115 in a predetermined orientation relative to oval cross section. It is important that the susceptor 115 lies in a plane P that is coincident with the long axis of the oval cross section. Therefore, irrespective of whether the consumable too is in either of the two predetermined orientations when inserted into the device 200, the orientation of the susceptor 115 relative to the device will be the same. This means that the consumable too of Fig. 7 affords the same advantages in system design as discussed above. In particular, the system may use an aerosol generator 202 that generates a smaller magnetic field than would otherwise be required if the susceptor were not in said known orientation and, therefore, the aerosol generator 202 may consume less power for a given level of heating.

Fig. 15 illustrates a system comprising the consumable too 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 too 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 too or, alternatively, on a mouthpiece (not shown) of the device 200 to inhale the aerosol. In the illustrated example, the consumable too and device 200 are configured so that mouth end 101 of the consumable too protrudes from the area 201 for receiving the consumable too when fully inserted into the device 200. Therefore, the consumable too is available for placing between the lips of the user while the user holds the device 200. The puff sensor 205 is configured to detect when a user is drawing on the consumable too 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 too. Alternatively, the device 200 maybe 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.

The area 201 for receiving the consumable too is provided with an inlet (not shown) to allow air into the area 201 for passing through the consumable too when a user inhales on the mouth end 101 of the consumable too. Therefore, a flow of air is directed through the consumable too when a user draws on the consumable too. The flow of air entrains the aerosol generated by the aerosol generating material 105 of the consumable too when heated by the aerosol generator 202.

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.

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 too. The varying magnetic field heats a susceptor 107, 115 that is placed within the area 201 for the receiving the consumable too by magnetic hysteresis. This example may be used, therefore, with a consumable too comprising a material heatable by a varying magnetic field, as described above. Therefore, when such a consumable too is placed within the device 200 and the aerosol generator 202 is activated, a varying magnetic field penetrates said material of the consumable too and causes heating of aerosol generating material 105 in thermal contact with said material, generating an aerosol for inhalation by a user. 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 too 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 too is received. The heat is transferred to the aerosol generating material 105 of the consumable too, 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 too and the consumable too may be configured for direct contact with the wall 207 for efficient heat transfer.

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 too. Therefore, when a consumable too 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 too is received. The heat is transferred to the aerosol generating material 105 of the consumable too, 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 too and the consumable too may be configured for direct contact with the wall 207 for efficient heat transfer. Fig. 16 schematically illustrates an example device 200 in which 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 aerosol generator 202 of Fig. 16 is configured to generate only the magnetic field required for penetrating the susceptor 115 in a predetermined orientation. It will be appreciated that, if the susceptor could be received within the device in any orientation, the aerosol generator would be required to surround the area for receiving the consumable. Instead, because the susceptor 115 is received within the device 200 in a predetermined orientation, the aerosol generator 202 may extend only around a portion of the area 201 for receiving the consumable. In the present example, the aerosol generator 202 comprises two induction heaters 208 disposed on opposite sides of the area 201 for receiving the consumable too. Fig. 17 shows elements 209 of the induction heaters 208 and their position relative to the susceptor 115 in its predetermined orientation. Other details of the device have been omitted from Fig. 17 for clarity. Each element 209 comprise a flat spiral shaped coil that lies in a plane parallel to a plane in which the susceptor 115 lies in its predetermined orientation. During activation of the device 200, a current is induced in each element causing a magnetic field to penetrate the susceptor 115 and heat it by magnetic hysteresis. Each element comprises connection points 210 for electrical connection to the battery 203. The receiving area 201 of the example of Fig. 6 may be replaced by the receiving areas of the examples of Figs. 9 and 11.

The particular example of Fig. 16 illustrates a device 200 comprising a receiving area 201 for use with the consumable of Fig. 14 (i.e. a device 200 comprising a receiving area shaped as illustrated in Fig. 13), however it will be appreciated that the teaching of the example of Fig. 16 can be extended to devices 200 with receiving areas 201 shaped as illustrated in Fig. 9 or Fig. 11 for receiving the consumables too of Fig. 10 and Fig. 12, respectively. The susceptor 115 will be effectively heated as long as each of the two elements 209 lie in a plane parallel to a plane in which the susceptor 115 lies in its predetermined orientation. This is illustrated by Fig. 18 and 19 which show the relative position of the elements 209 and the susceptor 115 for systems configured for use with the consumables of Figs. 6 and 7, respectively.
