This may help prevent deterioration of the material of the support element 11 when exposed to heat during use with the non-flammable aerosol providing device 100 (described below).

The material of the support element 11 is advantageously biodegradable to enable or enhance recycling of the consumable article 10 after use. The support element 11 made of cardboard or card advantageously improves the biodegradability of the article 10 . Advantageously, the material of the support element 11 complies with the European biodegradability standard EN 13430. Advantageously, the material of the support element 11 is compostable and can be decomposed aerobically via composting and complies with the European biodegradation standard EN 13432.

Any suitable material may be used for the construction of the support element 11 , and is not necessarily limited to cards, and instead, paper, cardboard, corrugated cardboard, plastic material, ceramic material, composite material, glass, metal, or metal alloy metal, or any combinations thereof.

The material of the support element 11 is advantageously resistant to oil or grease penetration. This may advantageously help to prevent leaching of components of the portions of the amorphous solid material 13 into the material of the support element 11 , which may If the components are partially dispersed from the amorphous solid material 13 , it may make the article 10 less effective in use. Such oil or high penetration resistance can be provided by the material of the support element 11 comprising a laminar construction, wherein one layer of material comprises a fluid-impermeable layer. In one embodiment, at least one of the first and second layers 11a, 11b may comprise a layered structure comprising a fluid-impermeable layer, and in one embodiment, the first and second layers 11a, 11b; 11b) both may comprise a layered structure comprising a fluid-impermeable layer.

5 and 6 show a non-flammable aerosol providing device 100 (hereinafter, for brevity, “device” 100 ) in which the article 10 of FIGS. 1-4 can be used as a non-flammable aerosol providing system. . The device 100 includes a housing 101 having an inlet 102 and an outlet 103 . An inlet 102 is provided at a first end of the device 100 and an outlet 103 is formed in the mouthpiece 104 at a second end of the device 100 opposite the first end. A first end of the device includes a slot 105 into which a consumable article 10 may be inserted to be received and retained within the device 100 for use of the device 100 .

6 shows a schematic diagram of the components within the housing 101 of the device 100 . 6 also shows the consumable article 10 received and held within the device 100 in a position for use of the device 100 . Device 100 includes a heater 106 comprising a plurality of heating elements 106a. Each of the heating elements 106a is positioned to correspond to the position of the respective region 12 of the amorphous solid material 13 of the consumable article 10 when the consumable article 10 is also received and held within the device 100 . it is decided In use, the device 100 is configured such that the heater 106 is capable of controllably heating at least one portion of the plurality of portions of the amorphous solid material 13 to generate an aerosol for inhalation. Each heating element 106a may be in direct contact with a respective portion of the amorphous solid material 13 , or may be in direct contact with a respective portion of the amorphous solid material 13 to heat the respective portion of the amorphous solid material 13 . It can be arranged closely adjacent but spaced apart.

Each of the heating elements 106a provides thermal energy to a specific portion of the amorphous solid material 13 to enable aerosolization of individual portions of the amorphous solid material 13 or from a portion of the amorphous solid material 13 . It may release one or more volatile substances to form an aerosol or entrain the aerosol. During use of the device 100 , one or more of the heating elements 106a may be activated to generate an aerosol/release volatiles from one or more of the portions of the amorphous solid material 13 .

The device 100 includes a power source 107 for supplying power to the heater 106 . Device 100 also includes a controller 108 , which is operable to control operation of heating elements 106a , coupled to power source 107 and heater 106 . A user interface 109 is provided on the housing 101 and coupled to the controller 108 . A user may enter operational commands into the device controller 108 to selectively control operation of the device 100 via the user interface 109 . The user command(s) may be received by the controller 108 via a wired or wireless interface, such that the device 100 may be operated via, for example, Bluetooth® or LAN or a smartphone or other such device. have. User interface 109 includes one or more manually actuable actuators, such as regions or buttons of a touch-sensitive screen, for manual actuation of device 100 and for a user to select a desired actuation of device 100 . can do.

In one example, the controller 108 is arranged to control the activation of certain heating elements 106a of the heater 106 to generate an aerosol. The selective activation of the heating elements 106a results in selective heating of portions of the amorphous solid material 13 such that a personalized aerosol is generated. Thus, the user can select materials that contribute to heating to generate the aerosol, thereby providing a personalized aerosol. Thus, "personalized aerosol" is used herein to mean that the user selects or at least is tailored to the user's needs in some way.

An airflow passageway 110 extends through the device 100 from an inlet 102 to an outlet 103 , and the consumable article 10 occupies when received and held within the device 100 . It is in fluid communication with a region within the housing 101 .

To use the non-combustible aerosol delivery system 1 described herein, a user inserts the consumable article 10 into the slot ( 105) is inserted. In the fully inserted position, portions of the amorphous solid material 13 lie opposite or proximate the respective heating elements 106a of the heaters 106 . The user then drives the device 100 through the user interface 109 to provide operational commands to the controller 108 to effect activation of specific heating elements 106a of the heater 106 . The heating elements 106a heat one or more of the regions of the amorphous solid material 13 of the article 10 to generate an aerosol and portion(s) of the amorphous solid material 13 for entrainment in the aerosol. ) releases one or more volatile substances from The user inhales the mouthpiece 104 , and ambient air is drawn into the airflow passageway 110 through the inlet 102 , through the airflow passageway 110 , and through the outlet 103 , into the user's mouth to be inhaled. drawn by The aerosol generated from the portion(s) of the amorphous solid material 13 is entrained in the airflow to be inhaled by the user.

In some embodiments, some or all of the portion of the amorphous solid material 13 may include one or more perforations 15 as illustrated in the second exemplary embodiment of the consumable article 10 illustrated in FIG. 7 . can In embodiments of non-flammable aerosol providing systems 1 in which portions of amorphous solid material 13 are disposed close to or in contact with heating elements 106a, gas and/or vapor are It may be possible to create from the surface of the amorphous solid material 13 adjacent to 106a). This may create or widen a gap between the surface of the heating element 106a and individual portions of the amorphous solid material 13 . Such a gap may be detrimental to the heating efficiency of the amorphous solid material 13 by the individual heating elements 106a. The perforations 15 advantageously direct any gas and/or vapor generated between the surface of the heating element 106a and the adjacent surface of the portion of the amorphous solid material 13 away from the heating element 106a. Venting through the portion of the material 13 may help prevent the portion of the amorphous solid material 13 from being forced away from the heater element 106a.

The perforations may be of any suitable size and number, and may advantageously comprise a single perforation disposed substantially centrally on the portion(s) of the amorphous solid material 13 , or as illustrated in FIG. 7 . It may include a plurality of perforations disposed in an array across the portion(s) of the amorphous solid material 13 . The amorphous solid material 13 may be perforated by a dermoabrasion roller or any other suitable means, and may be perforated during manufacture of the amorphous solid material or during manufacture of the consumable article 10 .

In the embodiment of the article 10 shown in FIGS. 1-4 , the apertures 14 extend completely through the support element. This can be beneficial for heating efficiency because the heat from the heating element 106a is transferred directly to the amorphous solid material 13 without other portions of the article 10 being significantly heated or absorbing thermal energy. Such a configuration may further be advantageous because the material of the support element 11 is not significantly heated during use or the material of the support element 11 is heated less. This may help to reduce or avoid unwanted aerosols, odors or flavors imparted by the material of the support element, such as, for example, avoiding a perceptible cardboard odor if the support material is made of cardboard. However, the scope of the present invention is not intended to be limited to this configuration of the article 10 in which the apertures 14 extend completely through the support element 11 .

An alternative configuration of a consumable article 10 of a third embodiment is illustrated in the cross-sectional view of FIG. 8 . The article 10 of Figure 8 appears in a front view similar to the article of the first embodiment shown in Figure 2, comprising six zones 12 of substantially uniform size and shape, arranged in two rows of three ( 1-4, any arrangement/number/size of zones may be provided within the scope of the present invention).

The difference from the article 10 of FIG. 8 is that the support element 11 is a one ply component comprising a single layer 11c. Six regions 12 of amorphous solid material 13 are provided in a cavity in the form of recesses 14c formed in the thickness of a single layer 11c. The recesses 14c extend partially but not completely through the thickness of the single layer 11c. The recesses 14c may be formed by any suitable method, for example by laser or mechanical cutting, milling, reaming, or by compressing selected areas of the layer 11c that will become regions 12 of amorphous solid material. have. The amorphous solid material may be provided in the recesses 14c by means of a sheet of solid material cut into appropriately sized sections and sections disposed within the recesses 14c or, for example, the recesses 14c ) can be provided to the recesses 14c in liquid form by pipetting into the recesses 14c and subsequently solidified within the recesses 14c. The solidifying step may include applying a setting agent to the liquid material in the recesses 14c.

The use of the article 10 of the third embodiment in the non-combustible aerosol providing system 1 would be the same as described above with reference to the first embodiment of the consumable article 10 . The heating elements 106a heat selected regions of the single layer 11c corresponding to the recesses 14c, and the heat passes through the material of the single layer 11c to individual regions of the amorphous solid material 13. is transmitted to Although the heating elements 106a must transfer heat through the material of the single layer 11c instead of directly heating the amorphous solid material 13, the single layer 11c is more in the regions of the recesses 14c. It is thin and therefore has less resistance to heat transfer through the thickness of the single layer 11c than if the heat had to be transferred through the entire thickness of the single layer 11c. Accordingly, the recesses 14c of the third embodiment of the consumable article 10 help prevent a decrease in the efficiency of heat transfer to the amorphous solid material.

A consumable article 10 of a fourth embodiment is shown in the schematic cross-sectional view of Fig. 9 and shown in a front view similar to the article of the first embodiment shown in Fig. 2, comprising six zones 12 of substantially uniform size and shape. and arranged in two rows of three (although mentioned with reference to the embodiment of the article in FIGS. 1 to 4 , any arrangement/number/size of zones may be provided within the scope of the present invention).

The support element 11 of the article 10 of FIG. 9 comprises a two-ply component comprising a first layer 11a and a second layer 11d. The first layer 11a includes a plurality of apertures 14a extending entirely through the thickness of the first layer 11a. The difference from the consumable article 10 of the fourth embodiment is that the second layer 11d does not include apertures extending through its thickness. Instead, the second layer 11d comprises a carrier or substrate on which discrete regions 12 of amorphous solid material 13 are formed. The first and second layers 11a, 11d are bonded together to form a two-ply support element 11 and portions of the amorphous solid material 13 are located within respective apertures 14a of the first layer 11a. do. The layers 11a, 11d may be joined by any suitable bonding agent such as PVA or other adhesive, or may be bonded by non-adhesive means such as welding or other mechanical fixing method.

The amorphous solid material 13 may be provided on the second substrate layer 11d before the first and second layers 11a and 11d are bonded together. In this embodiment, the amorphous solid material 13 may be sandwiched between the second substrate layer 11d and the first layer 11a. Alternatively, the amorphous solid material 13 may be provided in the apertures 14a after the first and second layers 11a, 11d are bonded together. In the latter case, the amorphous solid material 13 may be provided by a solid material sheet cut into appropriately sized sections and sections disposed within the apertures 14a, or the apertures in liquid form. may be provided at 14a and subsequently solidified within the apertures 14a. The solidifying step may include applying a coalescing agent to the liquid material in the apertures 14a.

The use of the article 10 of the fourth embodiment in the non-flammable aerosol providing system 1 will be the same as described above with reference to the first embodiment of the consumable article 10 . The heating elements 106a heat a selected region of the second substrate layer 11d that corresponds to the regions 12 of the solid amorphous material 13 , and the heat passes through the material of the second substrate layer 11d to the amorphous It is delivered to the individual zones of solid material 13 . The heating elements 106a should transfer heat through the material of the second substrate layer 11d instead of directly heating the amorphous solid material 13 , however, the second layer 11d is the total amount of the support element 11 . thinner than the thickness, and thus less resistance to heat transfer through the thickness of the second single layer 11d than would be the case if heat had to be transferred through the entire thickness of the support element. In addition, the second substrate layer 11d may be formed of a material having good thermal conductivity, for example, a metal to increase heat transfer and heating efficiency from the heating elements 106a to the amorphous solid material 13 . In some embodiments, the second substrate or carrier layer 11d may include a metal foil such as aluminum foil.

A consumable article 10 of a fifth embodiment is shown in the schematic cross-sectional view of FIG. 10 and appears similar to the article of the first embodiment shown in FIG. 2 in a front view, and has six regions 12 of substantially uniform size and shape. and arranged in two rows of three (although mentioned with reference to the embodiment of the article in FIGS. 1 to 4 , any arrangement/number/size of zones may be provided within the scope of the present invention).

However, the difference from the article 10 of the sixth embodiment is that the substrate layer 11d is a multi-ply material comprising a primary substrate layer 11d' and a secondary substrate layer 11d''. ) is included.

The first and second layers 11a, 11d are bonded together as described above to form the support element 11 and portions of the amorphous solid material 13 are separated into the respective apertures 14a of the first layer 11a. ) is located in The amorphous solid material 13 is disposed on the primary substrate layer 11d'. The substrate layer 11d may comprise a two-layer material, such as a foil-backed card, and the primary substrate layer 11d' may include a metallic foil layer, such as an aluminum layer, 2 The tea base layer 11d'' may include a layer of other material such as a card or cardboard. This may provide increased structural strength to the article 10 .

The use of the article 10 of the sixth embodiment in the non-flammable aerosol providing system 1 would be the same as described above with reference to the fourth embodiment of the consumable article 10 . The heat from the heating elements 106a heats selected regions of the second substrate layer 11d corresponding to the regions 12 of the solid amorphous material 13 as with the article 10 of the fourth embodiment. . Heat is transferred to the individual regions of the amorphous solid material 13 through the material of the second substrate layer 11d. Again, advantageously, the second layer 11d is generally thinner than the total thickness of the support element 11 , so that the second single layer ( less resistance to heat transfer through the thickness of 11d). In embodiments where the second substrate layer 11d comprises a layer formed of a material with good thermal conductivity, for example a metal, heat transfer from the heating elements 106a to the amorphous solid material 13 and the heating efficiency will be increased. can Also, in a system that may use induction heating (discussed in more detail below), the primary substrate layer 11d' is such that the regions 12 of the amorphous solid material 13 are separated from the primary substrate layer 11d'.

The consumable articles 10 of the second to sixth embodiments, together with the advantages described above with respect to the article 10 of the first embodiment, include a plurality of discrete portions of the amorphous solid material 13 spaced apart from each other. include

The consumable article 10 of the seventh embodiment is shown in the exploded perspective view of Fig. 12 and, in a front view, similar to the article of the first embodiment shown in Fig. 2, comprising six zones 12 of substantially uniform size and shape. and arranged in two rows of three (although mentioned with reference to the embodiment of the article in FIGS. 1 to 4 , any arrangement/number/size of zones may be provided within the scope of the present invention).

The support element 11 of the article 10 of Fig. 11 is similar to the article 10 of the first embodiment shown in Figs. 1-4, and similar features retain the same reference numerals. The difference from the consumable article 10 of the seventh embodiment is that the amorphous solid material 13 is provided as a single sheet sandwiched between the first and second layers 11a, 11b. This may enable a simpler and more cost-effective method of manufacturing the article since only one portion of the amorphous solid material is required per consumable article 10 .

The sheet of amorphous solid material 13 may optionally include an array of dividing holes 16 bounding discrete regions 12 of amorphous solid material. These split holes are illustrated in FIG. 11 . These split holes may serve to reduce heat transfer by conduction through the amorphous solid material 13 from one zone 12 to an adjacent zone. This may mean that, for example, one zone 12 of the amorphous solid material 13 is selectively heated by one heating element 106a but an adjacent zone 12 of the amorphous solid material 13 is not intended to be heated. can be advantageous when This may be advantageous in precisely controlling the composition of the personalized aerosol generated by the device 100 by preventing aerosol or volatile generation from regions 12 that are not intended to be activated.

In an embodiment where the different regions 12 of the amorphous solid material 13 contain different compositions, the dividing holes 16 may additionally or alternatively be formed in one region 12 of the amorphous solid material 13 . It may help to reduce unwanted transfer of components to adjacent regions 12 of the amorphous solid material 13 . Different compositions may tend to diffuse into adjacent regions 12 due to concentration gradients within the amorphous solid material 13 , and dividing holes 16 may prevent or at least reduce the ability for such diffusion to occur.

This can be provided. In this case, applying the same heating patterns to different consumable articles 10 may result in different aerosol mixtures, all of which may be undesirable, and thus optionally, the composition of the current consumable article 10 may be It will be appreciated that the controller 108 controlling the heating must be notified so that the proper mixture can be produced.

Thus, in an embodiment of the present invention, the composition of portions of a given consumable article 10 may be obtained via the identification element 18 and the sensor 111 . Once identified, the composition of the parts on the consumable article 10 can be determined by, for example, preset mixtures, vaporization temperatures for different part materials, and/or (eg, to avoid undesirable mixtures). may be obtained from local or remote storage, along with any other configuration information regarding any limits or correlations between the parts, and the like.

Embodiments of the consumable articles 10 illustrated and described herein include planar planar elements. This can be advantageous for simplicity and thus for ease and cost of manufacture, and also for space efficiency of packaging. However, the present invention is not intended to be limited to this configuration. For example, the article 10 may be “V” or “U” shaped in cross-section, or may be of any other suitable configuration, and the slot 105 of the device is correspondingly shaped to receive the article 10 . This can be determined It is noted that in such alternative embodiments, the heater 106 in the device 100 may advantageously be suitably configured to align with the regions 12 of the amorphous solid material 13 of the associated consumable article 10 . will be understood

As used herein, the term “cavity” is intended to include apertures extending completely through the thickness of the element, and also recesses including cutouts, depressions or other features that extend partially through the thickness of the element. do.

In embodiments of the article 10 described herein, the aerosol generating material is described as being within at least one cavity. This is an aerosol generating material that is offset with respect to the thickness or plane of the support element or part thereof but is aligned with at least one cavity so as to be accessible therethrough, and also an aerosol generating material disposed within a cavity in the thickness or plane of the support element or part thereof. It is intended to include material.

In the examples described the heater 106 may be an electrically resistive heater 106 . However, in other examples, heater 106 may be a chemically activated heater that may or may not operate through exothermic reactions or the like. The heater 106 may be part of an induction heating system, wherein the heater 106 is an energy source for induction heating, such as a copper wire coil, and a support comprising one or more of its layers 11a, 11b, 11c, 11d. Element 11 or other component within device 100 may be or retain a susceptor or the like. The susceptor may be a metallic sheet, for example a sheet such as aluminum foil. In one example, the heating elements 106a are not all the same type of heating element. In one example, at least one heating element 106a of the heater 106 is an electrically resistive heater, the other heating element 106 is optionally a chemically activated heater, and the other heating element 106a is optionally an induction heater. to be.

The heater may comprise one or more electrically resistive heaters, including, for example, one or more nichrome resistive heater(s) and/or one or more ceramic heater(s). The heater may comprise one or more induction heaters comprising an arrangement comprising one or more susceptors capable of forming a chamber into which an article comprising an aerosol-capable material is inserted or otherwise positioned in use. Alternatively or additionally, one or more susceptors may be provided in the aerosolizable material. Also, other heating arrangements may be used.

The power source 107 may be, for example, a battery, such as a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (eg, lithium ion batteries), nickel batteries (eg, nickel-cadmium batteries) and alkaline batteries. The battery is electrically coupled to the heater 106 to supply electrical power when needed under the control of the controller 108 .

In one example, the plurality of regions 12 and the plurality of heating elements 106a of the amorphous solid material 13 may be different in number. For example, one heating element 106a may heat two zones 12 of amorphous solid material 13 if it is desired to always be heated together. Conversely, two heating elements 106a may be used for individual regions 12 of amorphous solid material 13 in one example, while in another example a larger region of amorphous solid material 13 . (12) can be used in concert to heat (eg, a major component of an aerosol, or more frequently consumed). Alternatively or additionally, the support element may be physically movable relative to the heater 106 to newly position one or more different regions 12 of the amorphous solid material 13 over the respective heater element 106a. , thereby enabling a new mixing palette. In one example, the plurality of zones 12 of the amorphous solid material 13 may be a sample or reservoir of aerosolable material, which may include nicotine and nicotine containing materials.

In use, the heating elements 106a may be activated simultaneously or may be activated with a delay between activations. This can be used to make certain notes of the aerosol more or less prevalent in the entire aerosol or smoking session. In one example, the specific heating element 106a may first heat a specific region 12 of the amorphous solid material 13 , eg a tobacco portion, to generate a tobacco aerosol for inhalation. This may be briefly followed by a different heating element 106a which heats the menthol zone 12 of the amorphous solid material 13 a second time to follow the tobacco aerosol with the menthol aerosol the user wishes to end the smoking session.

Various heating profiles may be supplied to the plurality of zones 12 of the amorphous solid material 13 to provide a personalized aerosol. Complex combinations of profiles can be utilized to generate very specific combinations of mixing and release times, so that the aerosol can be highly personalized.

In one example, the first heating element 106a heats the first region 12 of the amorphous solid material 13 for a first amount of time, and the second heating element 106a heats for a second amount of time. The second zone 12 of the amorphous solid material 13 is heated, wherein the first amount of time and the second amount of time are different. This allows for greater personalization of the aerosol. This also enables the generation of aerosols with different notes during the smoking session.

In one example, the first heating element 106a heats the first region 12 of the amorphous solid material 13 at a first power level, and the second heating element 106a heats the amorphous solid material at a second power level. Heats a second region 12 of material 13 , wherein the first power level and the second power level are different power levels. This further enables greater personalization of the generated aerosol. Because the emitted aerosol may be related to the power at which the heater 106a operates, the flavors may be released at different times of the session, leading to a level of control over the generation of different notes within the smoking session as above.

In the examples, the amorphous solid material 13 has a thickness of 1 mm. In alternative embodiments, the amorphous solid sheet material may have a thickness of 0.2 mm to 2 mm, or 0.4 mm to 1.8 mm, or 0.8 mm to 1.2 mm. However, the amorphous solid material may have any suitable thickness as described herein.

In some embodiments, the support or carrier comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or both sides of the material.

An aerosol modifying agent is a substance capable of modifying an aerosol during use. Aerosol modifiers may modify the aerosol in a manner that produces a physiological or sensory effect in the human body. Examples of aerosol modifiers are flavorants and sensates. Sensory agents produce sensoriceptive sensations that can be perceived through senses, such as a cool or sour sensation.

The aerosol-forming material may promote the generation of an aerosol by facilitating initial vaporization and/or condensation of the gas into an inhalable solid and/or liquid aerosol. In some embodiments, the aerosol-forming material may improve delivery of flavor from the aerosol-generating material.

In one embodiment, the aerosol generating component is capable of generating an aerosol from an aerosol-capable material without heating. For example, the aerosol-generating component may generate an aerosol from an aerosol-capable material without the application of heat, eg, via one or more of vibration, mechanical, pressurization, or electrostatic means.

In one embodiment, the aerosol-capable material may comprise an active material, an aerosol-forming material and optionally one or more functional materials. The active ingredient may include nicotine (optionally retained in tobacco or tobacco derivatives) or one or more other non-olfactory physiologically active ingredients. A non-olfactory physiologically active material is a material that is incorporated into an aerosol-capable material to achieve a physiological response other than olfactory perception.

In some cases, the amorphous solid sheet material may have a mass per unit area of 30 to 120 g/m 2 . In some embodiments, the amorphous solid sheet material may have an areal density of about 30 to 70 g/m 2 , or about 40 to 60 g/m 2 . In some embodiments, the amorphous solid may have an areal density of about 80 to 120 g/m 2 , or about 70 to 110 g/m 2 , or particularly about 90 to 110 g/m 2 .

In some examples, the amorphous solid in the form of a sheet may have a tensile strength of from about 200 N/m to about 900 N/m. In some examples, such as the amorphous solid does not include a filler, the amorphous solid can have a tensile strength of 200 N/m to 400 N/m, or 200 N/m to 300 N/m, or about 250 N/m.

In some examples, such as where the amorphous solid comprises a filler, the amorphous solid can have a tensile strength of 600 N/m to 900 N/m, or 700 N/m to 900 N/m, or about 800 N/m.

In some cases, the support element may also function as a flavor carrier, eg, the support element may be impregnated with a flavoring agent or tobacco extract.

In one case, the surface of the support element in contact with the amorphous solid may be porous. For example, in some cases the support element comprises paper. Porous support elements may be particularly suitable for making strong bonds with amorphous solid materials. The amorphous solid is formed by drying the gel, and without being limited by theory, when the slurry from which the gel is formed partially impregnates the porous support element, and thus the gel hardens and forms cross-links, It is believed that the support element is partially bound to the gel. However, in alternative embodiments, the support element may comprise a non-porous material as described above.

Moreover, the surface roughness may contribute to the bonding strength between the layers of the amorphous solid material and/or the support element. The paper roughness may suitably be in the range of 50 to 1000 Bekk seconds, suitably 50 to 150 Bekk seconds, suitably 100 Bekk seconds (measured over an atmospheric pressure interval of 50.66 to 48.00 kPa). (Beck smoothness tester is a tool used to determine the smoothness of a paper surface that leaks air at a specified pressure between a smooth glass surface and a paper sample, and the time (in seconds) for a fixed volume of air to seep between these surfaces is called "Beck smoothness" "lim)

In one particular case, the support element may comprise a paper-backed foil; The paper layer is brought into contact with the amorphous solid and the properties discussed in the previous paragraphs are provided by this contact. Alternatively, the foil layer may abut the amorphous solid. The foil backing is substantially impermeable and can also serve to conduct heat to the amorphous solid. In addition, the foil can prevent the water provided on the amorphous solid from being absorbed into the paper and weakening its structural integrity.

In other instances, paper and greaseproof paper laminates have also been found to be particularly useful in the present invention. The paper layer is in contact with the amorphous solid, and the sticky amorphous solid does not readily stick to the oil-resistant paper carrier backing.

In some cases, one or more of the surfaces of the support element other than the surface other than the layer attached to the first surface of the amorphous solid may be treated to prevent adhesion of the sticky amorphous solid once the amorphous solid has cured and dried. For example, the surfaces may be treated with PTFE (polytetrafluoroethylene) and/or other non-stick materials.

In some cases, the amorphous solid may have a thickness of from about 0.005 mm to about 1.0 mm. Suitably, the thickness may range from about 0.05 mm to about 0.2 mm, and may be about 0.09 mm.

A susceptor is a material that can be heated by penetration by a changing magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material, such that its penetration by a changing magnetic field causes inductive heating of the heating material. Since the heating material may be a magnetic material, its penetration by a changing magnetic field causes magnetic hysteresis heating of the heating material. The susceptor can be both electrically conductive and magnetic, so that the susceptor can be heated by both heating devices. A device configured to generate a changing magnetic field is referred to herein as a magnetic field generator.

Induction heating is a process in which an electrically conductive object is heated by impregnating the object with a changing magnetic field. This process is described by Faraday's law of induction and Ohm's law. An induction heater may include an electromagnet and a device for passing a changing current, such as alternating current, through the electromagnet. When the electromagnet and the heated object are relatively properly positioned so that the resulting changing magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are created inside the object. An object has resistance to the flow of currents. Thus, when these eddy currents are created in an object, their flow against the object's electrical resistance causes the object to heat up. This process is called Joule, ohmic or resistance heating. An object that can be inductively heated is known as a susceptor.

Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by impregnating the object with a changing magnetic field. A magnetic material may be considered to include many atomic-scale magnets or magnetic dipoles. When a magnetic field penetrates these materials, the magnetic dipoles align with the magnetic field. Thus, when a changing magnetic field, for example an alternating magnetic field as generated by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes with the varying magnetic field applied. This magnetic dipole reorientation causes heat generation in the magnetic material.

When an object is both electrically conductive and magnetic, penetrating the object with a changing magnetic field can cause both Joule heating and hysteresis heating in the object. Moreover, the use of magnetic materials may intensify the magnetic field, which may aggravate Joule heating.

In each of the above processes, heat is generated inside the object itself rather than by an external heat source by heat conduction, so the rapid change of the object, particularly through the selection of suitable object materials and geometries, appropriate varying magnetic field magnitudes and orientations for the object, A temperature rise and a more uniform heat distribution can be achieved. Moreover, induction heating and magnetic hysteresis heating do not need to provide a physical connection between the source of the changing magnetic field and the object, so design freedom and control over the heating profile can be greater and the cost can be lowered.
