Description

Consumable for use with an aerosol supply device
Technical Field
The present disclosure relates to the field of non-combustible aerosol supply systems, in particular to consumables for use with aerosol supplies, methods for manufacturing consumables for use with aerosol supplies, and aerosol supply systems comprising consumables and aerosol supplies.
Background
Smoking articles such as cigarettes, cigars, and the like burn tobacco during use to produce tobacco smoke. Alternatives to these types of articles release inhalable aerosols or vapors by heating without burning the release compound from the substrate material. These may be referred to as non-combustible smoking articles, aerosol-generating assemblies or aerosol-supplying devices.
One example of such a product is a heating device that releases a compound by heating without burning an aerosolizable material, which may be referred to as a solid aerosol-generating material. In some cases, the solid aerosol-generating material may contain tobacco material. Heating volatilizes at least one component of the material, typically forming an inhalable aerosol. These products may be referred to as heated non-combustion devices, tobacco heating devices, or tobacco heating products. Various arrangements for volatilizing at least one component of a solid aerosol-generating material are known.
Another example is a mixing device. These mixing devices contain a liquid source (which may or may not contain nicotine) which is vaporized by heating to produce an inhalable vapor or aerosol. The device additionally contains a solid aerosol-generating material (which may or may not contain tobacco material) and components of the material are entrained in an inhalable vapor or aerosol to produce an inhaled medium.

Detailed Description
The consumable of the present specification may alternatively be referred to as an article.
In some embodiments, the consumable comprises an aerosol generating material. The consumable may include an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol generator, an aerosol-generating area, a housing, a wrapper, an aerosol modifier, one or more active ingredients, one or more flavourings, one or more aerosol-former materials, and/or one or more other functional materials.
The device for heating the aerosol-generating material to be used with the consumable is part of a non-combustible aerosol supply system. The non-combustible aerosol supply system releases compounds from aerosol-generating material without burning the aerosol-generating material, such as electronic cigarettes, tobacco heating products, and hybrid systems that use a combination of aerosol-generating materials to generate an aerosol.
According to the present disclosure, a "non-combustible" aerosol provision system is a system in which the constituent aerosol-generating materials of the aerosol provision system (or components thereof) are not combusted (combust) or are not combusted (burn) in order to facilitate delivery of at least one substance to a user.
In some embodiments, the delivery system is a non-combustible sol supply system, such as a powered (powered) non-combustible sol supply system.
In some embodiments, the non-combustible aerosol supply system is an electronic cigarette, also referred to as an electronic cigarette device (VAPING DEVICE) or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosol-generating material is not required.
In some embodiments, the non-combustible sol supply system is an aerosol generating material heating system, also referred to as a heated non-combustion system. One example of such a system is a tobacco heating system.
In some embodiments, the non-combustible aerosol supply system is a hybrid system that uses a combination of aerosol-generating materials to generate an aerosol, one or more of which may be heated. Each aerosol-generating material may be in the form of a solid, liquid or gel, for example, and may or may not contain nicotine. In some embodiments, the mixing system comprises a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may comprise, for example, a tobacco or non-tobacco product.
In general, a non-combustible aerosol supply system may include a non-combustible aerosol supply device and a consumable for use with the non-combustible aerosol supply device.
In some embodiments, the present disclosure relates to a consumable comprising an aerosol-generating material and configured for use with a non-combustible aerosol supply device. Throughout this disclosure, these consumables are sometimes referred to as articles of manufacture.
In some embodiments, a non-combustible sol supply system, such as a non-combustible sol supply device thereof, may include a power source and a controller. For example, the power source may be an electric power source, an exothermic power source, or the like. In some embodiments, the exothermic power source comprises a carbon substrate that can be energized to distribute power in the form of heat to the aerosol-generating material or a heat transfer material proximate the exothermic power source.
In some embodiments, the non-combustible aerosol supply system may include a region for receiving a consumable, an aerosol generator, an aerosol generating region, a housing, a mouthpiece, a filter, and/or an aerosol modifier.
In some embodiments, a consumable for use with a non-combustible aerosol supply device may include an aerosol generating material, an aerosol generating material storage area, an aerosol generating material delivery component, an aerosol generator, an aerosol generating area, a housing, a wrapper, a filter, a mouthpiece, and/or an aerosol modifier.
According to a first aspect of the present disclosure, there is provided a consumable for use with an aerosol supply device. The consumable comprises a support, an aerosol-generating material and a substance to be delivered that can be caused to volatilize. The support supports the aerosol-generating material and the substance to be delivered volatilizes when the support or the aerosol-generating material is heated.
The consumable of the present disclosure has the advantage that the aerosol generating material and the substance to be delivered are separated from each other, as although they may, but need not, be physically close to each other, they may be located at different locations on or in the consumable, which may be handled differently or exhibit different behaviour during manufacture, storage and/or use of the consumable. The aerosol-generating material and the substance to be delivered may be different from each other and have different characteristics, such as an optimal temperature range for vaporization or aerosol formation, chemical composition of the vapor or aerosol derived from the aerosol-generating material and the substance to be delivered, storage characteristics, volatility, and speed and/or rate of volatilization. This may be advantageous when using the consumable, during storage of the consumable before use of the consumable, and/or when manufacturing the consumable.
References to a substance to be delivered in this disclosure should be understood to include references to a single substance or a mixture of two or more substances.
In some of the above embodiments, the support comprises a sorbent material and the sorbent comprises a substance to be delivered.
It should be understood that in this disclosure, discussion of an adsorbent comprising a substance to be delivered refers to a substance to be delivered that is absorbed into or onto an adsorbent material. This includes the following situations, in which:
The substance to be delivered enters the pores or interstices of the adsorbent material, but does not chemically interact with the adsorbent material,
The substance to be delivered enters the adsorbent material and chemically interacts with the adsorbent material,
The substance to be delivered forms a film of the substance to be delivered on the adsorbent material, but does not chemically interact with the adsorbent material, or
-The substance to be delivered forms a film of the substance to be delivered on the adsorbent material and chemically interacts with the adsorbent material to form an adsorbate (adsorbate).
In some embodiments of any of the above embodiments, the substance to be delivered is located or absorbed/adsorbed in one or more discrete regions of the adsorbent material and is not located outside of those discrete regions. In other embodiments, the substance to be delivered is located or absorbed/adsorbed in one or more discrete regions of the sorbent material at a higher concentration than the concentration of the substance to be delivered in portions of the sorbent material not in those discrete regions.
In some embodiments, the substance to be delivered is absorbed into or onto the adsorbent material by applying the substance to be delivered to the surface of the adsorbent material and allowing the substance to be delivered to be absorbed or adsorbed into the adsorbent material. The application may be, but is not limited to, via spraying, brushing, via roller application, or known printing techniques such as inkjet or valve jet printing.
The use of separate aerosol-generating materials and substances to be delivered has one or more advantages. One such advantage is that the substance to be delivered may be selected such that it forms an aerosol faster and/or at a lower temperature than an aerosol from the aerosol-generating material. This allows the user to experience the inhalation (puff) of aerosol faster than would be experienced with a consumable comprising only aerosol-generating material.
A further advantage is that the aerosol-generating material and the substance to be delivered may be selected to provide the user with a puff having the same taste throughout the puff, or the aerosol-generating material and the substance to be delivered may be selected to provide a puff having an initial first taste from the substance to be delivered followed by a second taste from the aerosol-generating material.
A further advantage is that the substance to be delivered may have a sufficiently low aerosol-forming temperature such that this temperature may be achieved by using heat dissipated from the aerosol-generating material or using heat that is not directed to/absorbed by the aerosol-generating material when the aerosol-generating material is heated. This increases the total amount or volume of aerosol (from the substance to be delivered and aerosol-generating material) that can be generated per unit of thermal energy applied to the consumable compared to a consumable comprising only aerosol-generating material.
The support may be a material suitable for forming the substrate. For example, the support may be or include paper, cardboard, paperboard, reconstituted material, plastic material, ceramic material, composite material, glass, metal or metal alloy. In some embodiments, the support comprises a susceptor (susceptor). In some embodiments, the susceptor is embedded within the material of the support. In some alternative embodiments, the susceptor is located on or attached to one or both sides (EITHER SIDE) or surfaces of the material.
The sorbent material is an absorbent or sorbent associated with the substance to be delivered and is a material suitable for use in a non-combustible sol supply system. Suitable materials for the adsorbent material are, but are not limited to, porous materials, dry gels (aerogel, xerogel, cryogel (cryogel)), fibrous materials (natural or synthetic), paper, cardboard, ceramics, wood, aerogel, activated carbon, porous polymers, sponges. In the consumables of the present disclosure, the sorbent material has a desired substance to be delivered that is absorbed or adsorbed into the structure of the sorbent material.
The adsorbent material may be heated to cause aerosolization of the substance to be delivered that is absorbed or adsorbed therein or thereon. The adsorbent material may be selected based on its thermal conductivity and the rate at which the substance to be delivered may be aerosolized and the aerosol exits the adsorbent material.
In some embodiments of any of the above embodiments, the at least one substance absorbed or adsorbed into/onto the adsorbent material comprises one or more of the following: a flavor, an active, a flavor mixture, an active mixture, a mixture of one or more flavors and one or more active, one or more solvents, and/or one or more aerosol generator or aerosol former materials.
In some embodiments of any of the above embodiments, the substance to be delivered may have an aerosolization temperature of 60 degrees celsius or greater.
In some of any of the above embodiments, the support may comprise a sorbent material. In some of any of the above embodiments, the support may be formed from a sorbent material.
The aerosol generator or aerosol former material may comprise one or more components capable of forming an aerosol. In some embodiments, the aerosol former material may include one or more of the following: glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1, 3-butanediol, erythrose, meso-erythrose, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixtures, benzyl benzoate, glycerol tributyrate, lauryl acetate, lauric acid, myristic acid and propylene carbonate.
In some of any of the above embodiments, the support comprises a sorbent material. In some embodiments, the support is a laminate comprising at least a first substrate and a second substrate, and at least one of the substrates is formed of a sorbent material. In some embodiments, there may be another substrate of the laminate for structural purposes, in particular to provide the desired handling characteristics to the consumable, for example to provide a degree of elastic rebound energy for deformation of the consumable, and/or to provide rigidity.
In some of any of the above embodiments, the sorbent material forms one or both of the first surface or the second surface of the support. In some embodiments, one surface of the support is composed of an adsorbent material and the other surface of the support is composed of a material that is a non-adsorbent material.
In some of any of the above embodiments, the surface of the support is formed of an impermeable material.
In some of any of the above embodiments, one of the surfaces of the support is formed by a susceptor.
In some embodiments of any of the above embodiments, the support is a laminate comprising at least three substrates, and the substrate that does not form the first surface or the second surface of the support is a susceptor.
Susceptors are materials that are heatable by penetration with a changing magnetic field (e.g., an alternating magnetic field). The susceptor may be an electrically conductive material such that penetration of the varying magnetic field therethrough causes inductive heating of the susceptor by resistive heating generated by eddy currents. The susceptor may be a magnetic material such that penetration of a varying magnetic field through it causes hysteresis heating of the susceptor. The susceptor may be electrically conductive and magnetic such that the susceptor is heatable by two heating mechanisms. The device configured to generate a varying magnetic field is referred to as a magnetic field generator.
The susceptor may comprise a ferromagnetic metal such as iron or an iron alloy, for example steel or an iron-nickel alloy. Some example ferromagnetic metals are 400 series stainless steel, such as grade 410 stainless steel, or grade 420 stainless steel, or grade 430 stainless steel, or similar grade stainless steel. Or the susceptor may comprise a suitable non-magnetic, in particular paramagnetic, electrically conductive material, such as aluminium. In paramagnetic conductive materials, induction heating is performed only by resistance heating caused by eddy currents. Or the susceptor may comprise a non-conductive ferrimagnetic material, such as a non-conductive ferrimagnetic ceramic. In this case, heat is generated only by hysteresis loss. Susceptors may include commercial alloys such as Phytherm 230 (composition (wt.% = wt.%) 50 wt.% Ni, 10 wt.% Cr and the rest of Fe) or Phytherm 260 (composition 50 wt.% Ni, 9 wt.% Cr and the rest of Fe).
In some of any of the above embodiments, the susceptor may be a metal foil, optionally an aluminum or ferrous foil. Or in some of any of the above embodiments, the susceptor may be any conductor capable of being sprayed or vapor deposited on the material forming the support.
In some of any of the above embodiments, the sorbent material forms a first surface and a second surface of the support.
In some of any of the above embodiments, the support is formed entirely of the adsorbent material.
In one embodiment of any of the above embodiments, the support comprises a base of support material, and the support material comprises one or more of: paper, cardboard, paperboard, reconstituted material, plastic material, ceramic material, composite material, glass, metal or metal alloy.
In one embodiment of any of the above embodiments, the support comprises a plastic material capable of withstanding temperatures typically encountered in a non-combustible sol supply device. In some embodiments, the support comprises Polyetheretherketone (PEEK). Such an embodiment has the following advantages: the support is reusable and is less susceptible to any condensation in the non-flammable sol supply device than a consumable comprising a support comprising an adsorbent material for structural purposes.
In some of any of the above embodiments, the aerosol-generating material is supported on a surface of a support that is not a sorbent material. This arrangement has the following effects: during manufacture, subsequent storage and use of the consumable, the aerosol-generating material, as well as any components of the aerosol-generating material, are not adsorbed/absorbed into the support or adsorbent material.
In some of any of the above embodiments, the aerosol-generating material is supported on a surface of a support formed from the adsorbent material.
In some of any of the above embodiments, the substance to be delivered is supported on a surface of a support.
In some of any of the above embodiments, the consumable further comprises a sorbent material that is not part of the support, is supported on the support, and comprises a substance to be delivered.
In some of any of the above embodiments, the aerosol-generating material is supported on a first surface of the support body and the sorbent material is supported on one or both of the first surface and the second surface of the support body. In these embodiments, the adsorbent material is not part of the support, but is supported on the surface of the support. This arrangement has the following advantages: the adsorbent material may be supported on the support only at locations where the adsorbent material to be positioned is required.
In some of any of the above embodiments, the aerosol-generating material and the adsorbent material are both located on the consumable such that heating the aerosol-generating material causes at least one component of the aerosol-generating material to aerosolize as well as heating at least a portion of the adsorbent material. The heating of at least a portion of the adsorbent material may be by heat conduction from the aerosol-generating material and/or a support portion supporting the aerosol-generating material. Such heating of the adsorbent material may be considered as indirect heating.
Such indirect heating may result in the adsorbent material being heated to a temperature below the temperature at which the aerosol-generating material is heated, but to a temperature sufficient to cause the substance to be delivered to volatilize. In some embodiments, the heating properties of the adsorbent material may be affected by the shape of the adsorbent material and its proximity to the aerosol-generating material.
In some of any of the above embodiments, the support may include or support means (means) for regulating or facilitating heat transfer from the aerosol-generating material and/or the support portion supporting the aerosol-generating material to the sorbent material.
In some of any of the above embodiments, the sorbent material comprises at least one discrete region. Each discrete region is a volume of adsorbent material that can be positioned relative to the aerosol-generating material such that heating the aerosol-generating material causes at least one component of the aerosol-generating material to aerosolize resulting in the adsorbent material in the discrete region being heated to a sufficiently high temperature to cause volatilization or aerosolization of at least one substance absorbed or adsorbed therein. The adsorbent material may comprise one or more discrete regions.
In some of any of the above embodiments, the substance to be delivered volatilizes for a period of time PS after the start of heating the support or aerosol-generating material, the aerosol-generating material is configured to release the aerosol for a period of time PA after the start of heating the support or aerosol-generating material, and the period of time PS is less than or equal to PA. In some embodiments, the period PS is less than PA.
In some embodiments of any of the above embodiments, the sorbent material comprises one or more discrete regions, and the concentration of the substance to be delivered in the discrete region sorbent material may be made greater (in some embodiments significantly greater) than those not in the discrete region sorbent material portion. The relative concentration of the substance to be delivered in the discrete region and outside the discrete region may be determined by the location where the substance to be delivered is absorbed/adsorbed into the adsorbent material.
In some of any of the above embodiments, the discrete regions are identifiable only by relative location on the consumable and/or by concentration of the substance to be delivered in the discrete region sorbent material.
In other alternative embodiments, the discrete region has a shape and size at least partially defined by an adsorbent material surrounding the discrete region, the surrounding adsorbent material having a reduced ability to adsorb at least one substance to the adsorbent material relative to the ability to adsorb at least one substance to be delivered into the discrete region adsorbent material.
In some embodiments, the ability of the sorbent material at least partially surrounding the discrete region to adsorb the substance to be delivered may be affected by adsorbing/absorbing the non-volatile substance into the sorbent material at least partially surrounding the discrete region. In some other embodiments, the surface of the sorbent material at least partially surrounding the discrete regions may be treated to limit the permeability of the surface to the substance to be delivered to less than the permeability of the surface of the discrete regions. In some embodiments, at least 50%, at least 60%, at least 70%, at least 80%, or at least 90% less than the surface of the discrete region.
Preventing or limiting the extent to which the substance to be delivered is adsorbed into the adsorbent material in areas of the adsorbent material where it is not desirable to include the substance to be delivered may result in a reduction in the substance to be delivered used in the manufacture of the consumable product, thereby saving costs. Such prevention or restriction may also make use of the consumables of the present disclosure more consistent than would be achieved if the location of the substance to be delivered in the sorbent material was not controlled.
In some embodiments of any of the above embodiments, there are at least two discrete regions, and at least two of the discrete regions comprise different substances to be delivered or different mixtures of substances to be delivered.
In some of any of the above embodiments, the aerosol-generating material is supported on the support in one or more discrete portions, and at least one discrete region is associated with each discrete portion of the aerosol-generating material.
In some of any of the above embodiments, the surface of the support on which the discrete portions of aerosol-generating material are supported comprises or supports a sorbent material comprising discrete regions and the discrete regions substantially surround the discrete portions of aerosol-generating material. This arrangement has the following advantages: when the discrete portions of aerosol-generating material are heated, the adsorbent material of the discrete regions is indirectly heated by the discrete portions of aerosol-generating material.
In some of any of the above embodiments, the consumable comprises discrete portions of aerosol-generating material located on a first surface of the support and discrete regions of adsorbent material are located on a second surface of the support, and the discrete portions and the discrete regions of aerosol-generating material are located in respective positions on their respective surfaces. By the respective positions, it will be appreciated that when one of the discrete portions and discrete regions of the aerosol-generating material is viewed from a position perpendicular to the surface on which it is located, the one of the discrete portions and discrete regions of the aerosol-generating material substantially covers the other of the discrete portions and discrete regions of the aerosol-generating material.
In some of any of the above embodiments, the shape of the discrete portions of aerosol-generating material and the shape of the discrete regions in the plane of the first and second surfaces of the support are substantially the same.
In some of any of the above embodiments, the discrete portion of aerosol-generating material covers a first region on the surface of the support supporting it, the discrete region covers a second region on the surface of the support supporting it, and one of the first region and the second region is larger than the other of the first region and the second region.
In some of any of the above embodiments, the consumable includes one or more perforations (perforation) extending at least between the first surface and the second surface of the support. This arrangement has the following advantages: when the consumable is in use, aerosol generated on one side of the support or from a first surface of the support may pass through the perforations to the other side or second surface of the support. This is advantageous because in some embodiments it allows aerosol generated from aerosol-generating material on one side or surface of the support to be mixed with aerosol generated from adsorbent material on the other side or surface of the support. As a result, the two aerosols may be mixed before inhalation by the user and then delivered to the mouthpiece.
It should be understood that in this disclosure, the term "numerical value" is intended to mean zero, one, or more than one.
In some of any of the above embodiments, the one or more perforations extend at least between one of the first side or surface of the support and a face of the consumable adjacent the other side or surface of the support. In such embodiments, the perforations extend through the support and, for example, a portion of the aerosol-generating material supported on the surface of the support, or in alternative examples, through the support and through a portion of the sorbent material supported on the surface of the support.
In some embodiments of any of the above embodiments, the one or more perforations extend between a face of the consumable adjacent the first side or surface of the support and a face of the consumable adjacent the second side or surface of the support. In such embodiments, the perforations may extend through the support, a portion of the aerosol-generating material, and a portion of the adsorbent material.
In some of any of the above embodiments, the at least one perforation has a blind first end within the consumable and the other end opens through a surface of one of the support, the substance to be delivered, the aerosol-generating material, or the surface of the consumable. The blind end is the end in the material, so that the end of the perforation is closed by the material.
In some of any of the above embodiments, the perforations have a cross-sectional area of at least 0.01mm 2, at least 0.05mm 2, at least 0.1mm 2, at least 0.5mm 2, at least 1mm 2, at least 2mm 2, or at least 3mm 2.
In one embodiment of any of the above embodiments, the aerosol-generating material supported on the support body is positioned such that there is a support band on both surfaces of the support body that extends a predetermined distance onto the support body from an edge of the support body that is free of aerosol-generating material. The strip may extend the same distance from the support edge over the entire length of the support edge. The tape may facilitate handling of the consumable during use and/or packaging. The band may be continuous along the entire length of the support edge or it may be discontinuous. The strip may extend to different distances onto the support surface at different locations around the edge of the support.
According to a second aspect of the present invention there is provided a method of manufacturing a consumable for use with an aerosol provision device, wherein the consumable comprises a support, an aerosol generating material and at least one substance, wherein the method comprises the steps of:
a) Providing a support;
b) A slurry of aerosol-generating material is applied to the surface of the consumable,
C) The applied aerosol-generating material is dried and,
D) At least one substance is applied to the adsorbent material of the consumable surface.
An advantage of the method of the second aspect of the present disclosure is that the application of the aerosol-generating material and the substance to be delivered to the support may be performed separately in time and space. This capability overcomes the known problems of manufacturing consumables for use with aerosol supplies.
It is known in the manufacture of consumables for use with aerosol provision devices to form a slurry of aerosol-generating material comprising a solvent which causes the aerosol-generating material to become a slurry and one or more different substances or groups of substances (e.g. one or more physiologically active materials and one or more flavourings or flavourings) which will form part of an aerosol when the consumable is used and the aerosol-generating material is aerosolized. However, solvents and those materials may have different evaporation rates at any given temperature.
In the manufacture of consumables, a slurry of aerosol generating material is applied to a surface of a support or sheet of material which is then cut to form a plurality of supports. The slurry is then dried to form or substantially fix the size of the aerosol-generating material on the surface on which it is supported. In some embodiments, the aerosol-generating material dries to form an aerosol-generating gel or aerosol-generating film. During the drying process, the solvent of the slurry evaporates, as does some of the material that forms part of the aerosol when the consumable is used. It has been found that during the drying of the slurry, the different evaporation rates of the solvent of the aerosol generating material and the various substances to be aerosolized have the following effects: it may be difficult to precisely control the amount of material that is to form part of the aerosol in the dry aerosol material. This can result in difficulty in achieving a consistent, predictable, and repeatable commercial product. Further effects are: a significant amount of the active substance incorporated into the slurry is lost before the slurry dries sufficiently to form a substantially fixed size aerosol-generating material, aerosol-generating gel or aerosol-generating film.
The method of the present disclosure allows the slurry to be formulated to include only those materials that do not evaporate in undesirable amounts during drying of the slurry. Those materials may be those that evaporate at a rate higher or significantly higher than the evaporation rate of the solvent under conditions where the slurry is dry.
In some embodiments of any of the above embodiments, the material that has heretofore evaporated in an undesirable amount during drying of the slurry may comprise all or some of the material of the present disclosure to be delivered. This reduces the amount of those materials lost by evaporation during the manufacturing process, which increases the efficiency of use of those materials and reduces the environmental problems of evaporation of those materials during the consumable manufacturing process.
A further advantage of the method of the present disclosure may be that the slurry may be subjected to a drying process involving higher temperatures than previously possible, thereby reducing the manufacturing time of the consumable.
In some of any of the above embodiments, step (b) is performed at any time after step (a), step (b) is followed by step (c), and step (d) is performed at any time after step (c). For example, there may be a period of days, weeks or months between steps (a) and (b) and/or between steps (c) and (d).
In some of any of the above embodiments, the method further comprises step (e) comprising providing a sorbent material.
In some embodiments of any of the above embodiments, step (e) is performed prior to step (d), and step (d) comprises applying the substance to be delivered to the sorbent material to form a sorbent material comprising the substance to be delivered, and if the support does not comprise a sorbent material, applying the sorbent material comprising the substance to be delivered to the consumable.
In some embodiments of any of the above embodiments, the sorbent material may be secured to the consumable at any time during the manufacturing process. It will be appreciated that the adsorbent material may be such that it is not affected by the drying process of the slurry of aerosol-generating material. In some embodiments, the sorbent material is secured to the support.
In some embodiments of any of the above embodiments, the support of step (a) comprises a sorbent material.
In some of any of the above embodiments, step (e) comprises applying a paste to the consumable and subsequently drying the paste, the paste drying to form the adsorbent material. Such method steps may allow the adsorbent material to be applied to only predetermined portions of the support. In some embodiments, the drying of the paste is simultaneous with step (c).
In some of any of the above embodiments, step (e) comprises forming the adsorbent material in a desired shape, and securing the adsorbent material in the desired shape to a desired location on the consumable. This method of shaping and then securing the adsorbent to the support allows the adsorbent material to be molded or cut from larger units of adsorbent material (e.g., sheets of adsorbent material).
In some of any of the above embodiments, steps (e) and (d) comprise providing a sheet of sorbent material, applying an adhesive on the first surface and covering the adhesive with a removable carrier sheet, applying the substance to be delivered to another surface of the sorbent material and allowing the substance to be delivered to absorb into or onto the sorbent material, and cutting the sorbent material into one or more desired shapes.
The adhesive may be a releasable adhesive, a repositionable adhesive, a low tack adhesive, or other suitable adhesive.
The sorbent material may then be stored or transported to the consumable, the carrier sheet peeled off the sorbent material, and the sorbent material may then be adhered to the desired location of the consumable. The sorbent material may adhere to the consumable during manufacture of the consumable.
Or a user of the consumable may adhere the adsorbent material to the consumable prior to use of the consumable. This would allow a user to obtain one or more portions of the adsorbent material containing different substances to be delivered (e.g. flavours), select the flavouring they wish to use and apply the flavouring to the consumer product. This embodiment facilitates the user's selection and control of their experience, and facilitates the manufacturer that they can manufacture a limited range of consumables, but these consumables can be used with a wider range of substances to be delivered.
In some of any of the above embodiments, step (d) is performed prior to the sorbent material being secured to the consumable. This may have the following advantages: the absorption/adsorption of the substance to be delivered into the adsorbent material may be performed at a location remote from the manufacturing location of the consumable of the present disclosure.
In some embodiments of any of the above embodiments, steps (b) and (c) are repeated one or more times before step (d). In some embodiments, repetition of steps (b) and (c) may allow the aerosol-generating material to aggregate on the consumable. In some embodiments, those layers may be formed of aerosol-generating materials of different compositions.
In some embodiments of any of the above embodiments, the aerosol-generating material may be applied to one or more discrete regions of the consumable. In some embodiments, at least two of the different discrete regions of the consumable may be formed of aerosol-generating materials of different compositions to each other, and steps (b) and (c) may be repeated for each different composition of aerosol-generating material.
In some of any of the above embodiments, step (c) comprises using one or more of time, conduction heat, radiant heat, or air movement across the exposed surface of the aerosol-generating material.
In some of any of the above embodiments, the method comprises an additional step (f) comprising providing a susceptor and securing the susceptor to the support. This step is included when heating the aerosol-generating material using magnetic induction techniques or a combination of magnetic induction techniques and resistive heating techniques. In the case where only resistive heating techniques are used to heat the consumable, the susceptor need not be provided, but may be present.
In some embodiments of any of the above embodiments, step (f) is performed after step (a) and the susceptor is fixed to the first surface of the support, step (b) is performed after step (f), and the slurry of aerosol-generating material is applied at least partially to the susceptor. In some embodiments, the susceptor is a metal foil and all aerosol-generating material is applied to the susceptor.
In some embodiments of any of the above embodiments, the support is a sheet of material and the method includes step (h) comprising cutting the support into two or more consumables. This method is advantageous because it facilitates handling of the support during manufacture, because sheets of material having larger material dimensions than are typically required for forming consumables for handheld aerosol supplies can be handled more easily. The support may be cut to form consumables of any desired shape, such as square, rectangular or circular.
In some of any of the above embodiments, the method includes step (i) comprising perforating at least the support to form one or more perforations. One or more of those perforations may extend at least between the first surface and the second surface of the support, one or more of those perforations may extend at least between one of the first surface or the second surface of the support and a face of the consumable adjacent to the other of the first surface or the second surface of the support, one or more of those perforations may extend between a face of the consumable adjacent to the first surface of the support and a face of the consumable adjacent to the second face of the support, one or more of those perforations may extend at least through the sorbent material, one or more of those perforations may extend at least through the aerosol-generating material, or one or more of those perforations may extend between a blind first end within the consumable and another end of the surface opening through one of the support, the substance to be delivered, the aerosol-generating material, or the face of the consumable.

The aerosol-generating material may be formed by: (a) forming a slurry comprising components of the aerosol-generating material or a precursor thereof, (b) forming a slurry layer, (c) setting the slurry to form a gel, and (d) drying to form the aerosol-generating material.
(B) Forming the slurry layer typically includes spraying, casting, or extruding the slurry. In an example, the slurry layer is formed by electrospraying a slurry. In an example, the slurry layer is formed by casting a slurry.
In some examples, (b) and/or (c) and/or (d) are performed at least partially simultaneously (e.g., during electrospraying). In some examples, (b), (c), and (d) are performed sequentially.
In some examples, the slurry is applied to a support. The layer may be formed on the support.
In an example, a slurry includes a gelling agent, an aerosol former material, and an active substance. The slurry may comprise any of these components in any of the proportions given herein with respect to the composition of the aerosol-generating material. For example, the slurry may comprise (on a dry weight basis):
-a gelling agent and optionally a filler, wherein the amount of gelling agent and filler add up to about 10 to 60wt% of the slurry;
-an aerosol former material in an amount of about 40 to 80wt% of the slurry; and
-Optionally an active substance in an amount of up to about 20wt% of the slurry.
Setting (c) the gel may include supplying a setting agent to the slurry. For example, the slurry may contain sodium, potassium or ammonium alginate as a gel precursor, and a setting agent containing a calcium source (e.g., calcium chloride) may be added to the slurry to form a calcium alginate gel.
In examples, the setting agent comprises or consists of calcium acetate, calcium formate, calcium carbonate, calcium bicarbonate, calcium chloride, calcium lactate, or a combination thereof. In some examples, the setting agent comprises or consists of calcium formate and/or calcium lactate. In certain examples, the setting agent comprises or consists of calcium formate. The inventors have found that in general, the use of calcium formate as a coagulant results in an aerosol-generating material having greater tensile strength and greater elongation resistance.
The total amount of coagulants such as calcium sources may be 0.5-5wt% (dry weight basis). Suitably, the total amount may be from about 1wt%, 2.5wt% or 4wt% to about 4.8wt% or 4.5wt%. The inventors have found that adding too little coagulant may result in the aerosol-generating material being unable to stabilize the aerosol-generating material components and in these components exiting from the aerosol-generating material (drop out). The inventors have found that the addition of too much coagulant results in the aerosol-generating material being very viscous and thus having poor operability.
When the aerosol-generating material is free of tobacco, a higher amount of coagulant may need to be applied. In some cases, therefore, the total amount of coagulant may be 0.5 to 12wt%, such as 5 to 10wt%, on a dry weight basis. Suitably, the total amount may be from about 5wt%, 6wt% or 7wt% to about 12wt% or 10wt%. In this case, the aerosol-generating material is generally free of any tobacco.
In an example, supplying the coagulant to the slurry includes spraying the coagulant onto the slurry, e.g., a top surface of the slurry.
Alginate is a derivative of alginic acid and is typically a high molecular weight polymer (10-600 kDa). Alginic acid is a copolymer of β -D-mannuronic acid (M) and α -L-guluronic acid (G) units (blocks) linked together by (1, 4) -glycosidic bonds to form a polysaccharide. Upon addition of the calcium cations, the alginate crosslinks to form a gel. It has been found that alginates with a high G monomer content form a gel more readily upon addition of a calcium source. Thus, in some cases, the gel precursor may comprise alginate, wherein at least about 40%, 45%, 50%, 55%, 60% or 70% of the monomer units in the alginate copolymer are alpha-L-guluronic acid (G) units.
In examples, drying (d) removes about 50wt%, 60wt%, 70wt%, 80wt%, or 90wt% to about 80wt%, 90wt%, or 95wt% (WWB) of water in the slurry.
In an example, drying (d) reduces the casting material thickness by at least 80%, suitably 85% or 87%. For example, the thickness of the slurry casting is 2mm, and the thickness of the resulting dried aerosol-generating material is 0.2mm.
In some examples, the slurry solvent consists essentially of or consists of water. In some examples, the slurry comprises about 50wt%, 60wt%, 70wt%, 80wt%, or 90wt% solvent (WWB).
In examples where the solvent consists of water, the dry weight content of the slurry may be matched to the dry weight content of the aerosol-generating material. Thus, the discussion herein relating to solid compositions is explicitly disclosed in connection with the slurry aspects of the present invention.
The aerosol-generating material may comprise a flavour. Suitably, the aerosol-generating material may comprise up to about 80wt%, 70wt%, 60wt%, 55wt%, 50wt% or 45wt% flavour. In some cases, the aerosol-generating material may comprise at least about 0.1wt%, 1wt%, 10wt%, 20wt%, 30wt%, 35wt% or 40wt% of the flavouring (all on a dry weight basis). For example, the aerosol-generating material may comprise 1 to 80wt%, 10 to 80wt%, 20 to 70wt%, 30 to 60wt%, 35 to 55wt% or 30 to 45wt% flavour. In some cases, the flavoring comprises, consists essentially of, or consists of menthol.
The aerosol-generating material may comprise a filler.
In some embodiments, the aerosol-generating material comprises less than 60wt% filler, for example 1wt% to 60wt%, or 5wt% to 50wt%, or 5wt% to 30wt%, or 10wt% to 20wt%.
In other embodiments, the aerosol-generating material comprises less than 20wt%, suitably less than 10wt% or less than 5wt% filler. In some cases, the aerosol-generating material comprises less than 1wt% filler, and in some cases, no filler.
In some such cases, the aerosol-generating material comprises at least 1wt% filler, for example at least 5wt%, at least 10wt%, at least 20wt%, at least 30wt%, at least 40wt% or at least 50wt% filler. In some embodiments, the aerosol-generating material comprises from 5 to 25wt% filler.
The filler, if present, may comprise one or more inorganic filler materials, such as calcium carbonate, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, magnesium carbonate, and suitable inorganic adsorbents such as molecular sieves. The filler may comprise one or more organic filler materials such as wood pulp, cellulose and cellulose derivatives (e.g., methylcellulose, hydroxypropyl cellulose, and carboxymethyl cellulose (CMC)). In certain cases, the aerosol-generating material does not comprise calcium carbonate, such as chalk.
In embodiments that include a filler, the filler is fibrous. For example, the filler may be a fibrous organic filler material such as wood pulp, hemp, cellulose or cellulose derivatives (e.g., methylcellulose, hydroxypropyl cellulose, and carboxymethyl cellulose (CMC)).
Without wishing to be bound by theory, it is believed that including fibrous fillers in the aerosol-generating material may increase the tensile strength of the material. This may be particularly advantageous in examples where the aerosol-generating material is provided as a sheet, for example when the sheet of aerosol-generating material surrounds a rod of aerosolizable material.
In some embodiments, the aerosol-generating material does not comprise tobacco fibers. In a specific embodiment, the aerosol-generating material does not comprise a fibrous material.
In some embodiments, the aerosol-generating material does not comprise tobacco fibers. In a specific embodiment, the aerosol-generating material does not comprise a fibrous material.
The aerosol-generating material may comprise one or more active substances and/or flavourings, one or more aerosol former materials, and optionally one or more other functional materials.
In some embodiments, the aerosol-generating material further comprises an active substance. For example, in some cases, the aerosol-generating material additionally comprises tobacco material and/or nicotine. In some embodiments, the aerosol-generating material comprises powdered tobacco and/or nicotine and/or tobacco extract.
In some cases, the aerosol-generating material may comprise from 5 to 60wt% (dry weight basis) of tobacco material and/or nicotine. In some cases, the aerosol-generating material may comprise from about 1wt%, 5wt%, 10wt%, 15wt%, 20wt% or 25wt% to about 70wt%, 60wt%, 50wt%, 45wt%, 40wt%, 35wt% or 30wt% (on a dry weight basis) of active substance.

For example, the aerosol-generating material may comprise from 10 to 50wt%, from 15 to 40wt% or from 20 to 35wt% of tobacco material. In some cases, the aerosol-generating material may comprise from about 1wt%, 2wt%, 3wt%, or 4wt% to about 20wt%, 18wt%, 15wt%, or 12wt% (on a dry weight basis) nicotine. For example, the aerosol-generating material may comprise from 1 to 20wt%, from 2 to 18wt% or from 3 to 12wt% nicotine.
In some cases, the aerosol-generating material comprises an active substance, such as a tobacco extract. In some cases, the aerosol-generating material may comprise from 5 to 60wt% (by dry weight) of the tobacco extract. In some cases, the aerosol-generating material may comprise from about 5wt%, 10wt%, 15wt%, 20wt%, or 25wt% to about 60wt%, 50wt%, 45wt%, 40wt%, 35wt%, or 30wt% (on a dry weight basis) of the tobacco extract. For example, the aerosol-generating material may comprise 10 to 50wt%, 15 to 40wt% or 20 to 35wt% of the tobacco extract. The tobacco extract may contain a concentration of nicotine such that the aerosol-generating material comprises 1wt%, 5wt%, 2wt% or 2.5wt% to about 6wt%, 5wt%, 4.5wt% or 4wt% (on a dry weight basis) nicotine. In some cases, the aerosol-generating material may be free of nicotine other than the nicotine produced by the tobacco extract.
In some embodiments, the aerosol-generating material does not comprise tobacco material, but comprises nicotine. In some such cases, the aerosol-generating material may comprise from about 1wt%, 2wt%, 3wt% or 4wt% to about 20wt%, 18wt%, 15wt% or 12wt% (on a dry weight basis) nicotine. For example, the aerosol-generating material may comprise from 1 to 20wt%, from 2 to 18wt% or from 3 to 12wt% nicotine.
In some cases, the total content of active and/or flavoring may be at least about 0.1wt%, 1wt%, 5wt%, 10wt%, 20wt%, 25wt%, or 30wt%. In some cases, the total content of active and/or flavoring may be less than about 90wt%, 80wt%, 70wt%, 60wt%, 50wt%, or 40wt% (all on a dry weight basis). In some cases, the total content of tobacco material, nicotine, and flavoring may be at least about 0.1wt%, 1wt%, 5wt%, 10wt%, 20wt%, 25wt%, or 30wt%. In some cases, the total content of active and/or flavoring may be less than about 90wt%, 80wt%, 70wt%, 60wt%, 50wt%, or 40wt% (all on a dry weight basis).
The aerosol-generating composition may comprise one or more active substances. In an example, the aerosol-generating material comprises one or more active substances, for example up to about 20wt% of the aerosol-generating material. In examples, the aerosol-generating material comprises the active in an amount of about 1wt%, 5wt%, 10wt% or 15wt% to about 20wt%, 15wt% or 5wt% of the aerosol-generating material.
The active substance may comprise a physiologically and/or olfactory active substance which is comprised in the aerosol-generating composition in order to achieve a physiological and/or olfactory response.
The tobacco material may be present in the aerosol-generating composition in an amount of about 50 to 95wt%, or about 60 to 90wt%, or about 70 to 90wt%, or about 75 to 85 wt%.
The tobacco material may be present in any form, but is typically fine cut (e.g., cut into narrow filaments). The fine cut tobacco material may advantageously be blended with an aerosol-generating material to provide an aerosol-generating composition having the tobacco material and aerosol-generating material uniformly dispersed throughout the aerosol-generating composition.
In examples, the tobacco material includes one or more of ground tobacco, tobacco fibers, cut tobacco, extruded tobacco, tobacco stems, reconstituted tobacco, and/or tobacco extracts. Surprisingly, the inventors have found that relatively large amounts of lamina tobacco (lamina tabacco) can be used in aerosol generating compositions and still provide acceptable aerosols when heated by a non-combustible aerosol delivery system. Lamina tobacco generally provides superior organoleptic properties. In examples, the tobacco material comprises lamina tobacco in an amount of at least about 50wt%, 60wt%, 70wt%, 80wt%, 85wt%, 90wt%, or 95wt% of the tobacco material. In specific examples, the tobacco material comprises cut tobacco in an amount of at least about 50wt%, 60wt%, 70wt%, 80wt%, 85wt%, 90wt%, or 95wt% of the tobacco material.

In some embodiments, the aerosol-generating material is a hydrogel and comprises less than about 20wt% water based on wet weight. In some cases, the hydrogel may comprise less than about 15wt%, 12wt%, or 10wt% water, calculated on a wet weight basis. In some cases, the hydrogel may comprise at least about 1wt%, 2wt%, or at least about 5Wt% Water (WWB).
The aerosol-generating material may have any suitable water content, for example from 1wt% to 15wt%. Suitably, the water content of the aerosol-generating material is from about 5wt%, 7wt% or 9wt% to about 15wt%, 13wt% or 11wt% (WWB), most suitably about 10wt%. The water content of the aerosol-generating material may be determined, for example, by karl fischer titration or gas chromatography with a thermal conductivity detector (GC-TCD).
In some cases, the aerosol-generating material may consist essentially of or consist of a gelling agent, water, an aerosol-generating agent, a flavoring, and optionally an active substance.
In some cases, the aerosol-generating material may consist essentially of or consist of a gelling agent, water, an aerosol-generating agent, a flavoring, and optionally a tobacco material and/or a nicotine source.
In an example, the aerosol-generating material consists essentially of or consists of a gelling agent, an aerosol-generating agent, an active substance and water.

-1-50wt% of a gelling agent;
-0.1-50wt% of an aerosol generator; and
-30-60Wt% of a flavouring;
Wherein these weights are on a dry weight basis.
In an alternative embodiment of the aerosol-generating material, the aerosol-generating material comprises:
-1-60wt% of a gelling agent;
-5-60wt% of an aerosol generator; and
-10-60Wt% of a tobacco extract;

In some cases, the aerosol-generating material may consist essentially of or consist of glycerin, alginate and/or pectin, tobacco extract, and water.
In some embodiments, the aerosol-generating material may have the following composition (DWB): a gelling agent (preferably comprising an alginate) in an amount of about 5wt% to about 40wt%, or about 10wt% to 30wt%, or about 15wt% to about 25 wt%; tobacco extract in an amount of about 30wt% to about 70wt%, or about 40wt% to 55wt%, or about 45wt% to about 50 wt%; an aerosol generating agent (preferably comprising glycerol) (DWB) in an amount of about 10wt% to about 50wt%, or about 20wt% to about 40wt%, or about 25wt% to about 35 wt%.
In one embodiment, the aerosol-generating material comprises about 20wt% alginate gelling agent, about 48wt% tobacco virginia extract, and about 32wt% glycerin (DWB).
The "thickness" of the aerosol-generating material describes the shortest distance between the first surface and the second surface. In embodiments in which the aerosol-generating material is in the form of a sheet, the thickness of the aerosol-generating material is the shortest distance between a first planar surface of the sheet and a second planar surface of the sheet opposite the first planar surface of the sheet.
In some cases, the layer of aerosol-forming aerosol-generating material has a thickness of from about 0.015mm to about 1.5mm, suitably from about 0.05mm to about 1.5mm or from 0.05mm to about 1.0 mm. Suitably, the thickness may be in the range of from about 0.1mm or 0.15mm to about 1.0mm, 0.5mm or 0.3 mm.
In some cases, the aerosol-generating material may have a thickness of about 0.015mm to about 1.0 mm. Suitably, the thickness may be in the range of about 0.05mm, 0.1mm or 0.15mm to about 0.5mm or 0.3 mm.
A material having a thickness of 0.2mm is particularly suitable. The aerosol-generating material may comprise more than one layer and the thicknesses described herein refer to the total thickness of those layers.
It has been observed that if the aerosol-generating material is too thick, the heating efficiency may be compromised. This adversely affects the power consumption in use. Conversely, if the aerosol-generating material is too thin, it is difficult to manufacture and handle; very thin materials are more difficult to cast and can be brittle, which compromises aerosol formation in use.
The thickness specified herein is the average thickness of the material. In some cases, the aerosol-generating material thickness may vary by no more than 25%, 20%, 15%, 10%, 5%, or 1%.
In some examples, the aerosol-generating material in sheet form may have a tensile strength of about 200N/m to about 900N/m. In some examples, the aerosol-generating material may have a tensile strength of 200N/m to 400N/m, or 200N/m to 300N/m, or about 250N/m, for example, where the aerosol-generating material does not include a filler.
Such tensile strength may be particularly suitable for embodiments in which the aerosol-generating material is formed into a sheet and then shredded and incorporated into an aerosol-generating article. In some examples, for example where the aerosol-generating material comprises a filler, the aerosol-generating material may have a tensile strength of 600N/m to 900N/m, or 700N/m to 900N/m, or about 800N/m. Such tensile strength may be particularly suitable for embodiments in which the aerosol-generating material is included in the aerosol-generating article/fitting as a rolled sheet, suitably in the form of a tube.
In some examples, the aerosol-generating material in sheet form may have a tensile strength of about 200N/m to about 2600N/m. In some examples, the aerosol-generating material may have a tensile strength of 600N/m to 2000N/m, or 700N/m to 1500N/m, or about 1000N/m. Such tensile strength may be particularly suitable for embodiments in which the aerosol-generating material is formed and incorporated as a sheet into an aerosol-generating consumable.
The aerosol-generating material may have any suitable areal density (mass per unit area), for example from 30g/m 2 to 120g/m 2. In some cases, the sheet may have a mass per unit area of 80-120g/m 2, or about 70 to 110g/m 2, or particularly about 90 to 110g/m 2, or suitably about 100g/m 2 (so that it has a density similar to that of cut tobacco and a mixture of these substances does not readily separate). In some cases, the sheet may have a mass per unit area of about 30 to 70g/m 2, 40 to 60g/m 2, or 25-60g/m 2, and may be used to encase an aerosolizable material such as tobacco.
All weight percentages (expressed as wt%) described herein are on a dry weight basis unless explicitly stated otherwise. All weight ratios are also on a dry weight basis. The weight quoted on a dry weight basis refers to all extracts or slurries or materials other than water and may include components that are themselves liquid at room temperature and pressure, such as glycerin. Conversely, weight percentages based on wet weight refer to all components including water.
The aerosol-generating material may comprise a colourant. The addition of a colorant may alter the visual appearance of the aerosol-generating material. The presence of a colorant in the aerosol-generating material may enhance the visual appearance of the aerosol-generating material. By adding a colorant to the aerosol-generating material, the aerosol-generating material may be color matched with other components of the article comprising the aerosol-generating material.
Depending on the desired color of the aerosol-generating material, a variety of colorants may be used. The colour of the aerosol-generating material may be, for example, white, green, red, violet, blue, brown or black. Other colors are also contemplated. Natural or synthetic colorants, such as natural or synthetic dyes, food grade colorants, and pharmaceutical grade colorants, may be used. In certain embodiments, the colorant is caramel, which may impart a brown appearance to the aerosol-generating material. In such embodiments, the color of the aerosol-generating material may be similar to the color of other components in the aerosol-generating material (e.g., tobacco material).
The colorant may be incorporated during formation of the aerosol-generating material (e.g. when forming a slurry comprising the material forming the aerosol-generating material) or may be applied to the aerosol-generating material after formation of the aerosol-generating material (e.g. by spraying it onto the aerosol-generating material).
In some of any of the above embodiments, talc powder, calcium carbonate powder or other powder is applied to the exposed surface of at least one discrete portion of the aerosol-generating material. This may reduce the tack or adhesion level of the aerosol-generating material.
In the following discussion of the figures, like reference numerals are used throughout for more than one embodiment when like elements are present, and like reference numerals (like numerals plus multiples of 100) are used when like elements are present.
Referring to fig. 1, the aerosol provision device 2 comprises a housing 4, and a heater apparatus 6 is located within the housing 4. The heater device 6 is composed of a heating chamber 8 and a heater 10. The heater 10 may be a resistive heater or a magnetic field generator for use with a susceptor.
The heating chamber 8 defines an opening or mouth 12 at a first end of the heating chamber 8. At the opposite end of the heating chamber 8 is an aperture 14. The aperture 14 is in fluid communication with the mouthpiece 16 via a conduit 18.
Also located within the housing 4 is a controller 20, the controller 20 being in electronic communication with the heater 10 and controlling the functions of the heater 10. The controller 20 may include a memory (not shown) in which one or more tables relating to the operation of the heater 10 may be stored. The heater 10 and controller 20 are powered by a power source 22. The power source 22 is a rechargeable battery. In other embodiments, the power source may be other suitable power sources.
The aerosol provision device 2 is suitable for use with a consumable 24. The consumable 24 is comprised of one or more discrete portions of the aerosol-generating material 26 supported on the first surface 30 of the support 28. Discrete portions of aerosol-generating material 26 are supported on the support 28 in a square grid pattern. Other not shown embodiments of the consumable 24 may include more or less discrete portions of the aerosol-generating material 26 than shown in fig. 1, including individual portions of the aerosol-generating material 26, and these portions may be distributed in any pattern over the surface of the support 28. The discrete portions of aerosol-generating material 26 are shown in fig. 1 as having an approximately circular shape, in other embodiments they may have other shapes.
Referring to fig. 2, the support 28 is a laminate having three substrates or layers 34, 36, 38. Layer 34 forms first surface 30 and is comprised of a layer of aluminum foil. When the consumable 24 is used, the layer 34 may act as a susceptor and heat discrete portions of the aerosol-generating material 26. In other not shown embodiments, the susceptor layer 34 may be formed of other susceptor materials. In this embodiment, the susceptor layer 34 is impermeable.
Layer 36 of support 28 is a support layer and is present to give consumable 24 sufficient strength so that consumable 24 does not deform or bend during normal use. Layer 28 may be formed from card or plastic materials such as Polyetheretherketone (PEEK). It should be understood that layer 36 may comprise other materials.
The layer 38 of the support 28 is composed of a material that is an adsorbent (i.e., absorbent or adsorbent) for at least one substance 40 to be delivered. The substance to be delivered 40 is a substance that is desired to be included in the aerosol generated when the aerosol-generating material 26 is heated and the user draws from the aerosol-supply device 2. The sorbent layer 38 forms the second surface 32 of the support 48.
In some embodiments, the substance 40 to be delivered is applied to the sorbent layer 38 on the second surface 32 in locations corresponding to locations of the discrete portions of the aerosol-generating material 26 on the first surface 30 of the support, and the substance to be delivered is only allowed to diffuse within the sorbent layer 38. In other embodiments, and with reference to fig. 3, on the second surface 32 of the support 28, one or more discrete areas 42 are each defined by a boundary 44 (represented by a line 44). The boundary 44 helps retain the substance 40 to be delivered within the discrete region 42.
The boundary 44 is located at the interface of the adsorbent material inside the discrete region 42 having the first absorbency/adsorbtion level (X) and the adsorbent material outside the discrete region 42 having the second absorbency/adsorbtion level (Y), and X is greater than Y. The absorbency/adsorptivity level Y of the adsorbent material outside of the discrete areas 42 is a result of treating the adsorbent material to reduce its absorbency/adsorptivity level.
In some embodiments, not shown, the boundaries 44 of the discrete regions 42 may have the same shape as the discrete portions of the aerosol-generating material 26. In some embodiments, they may surround a region of the second surface of the support that is different from a region of the first surface of the support that is covered by the discrete portions of the aerosol-generating material 26.
The substance 40 to be delivered comprises one of the following: a flavoring, an active, a mixture of flavoring, a mixture of active, or a mixture of one or more flavoring and one or more active. In one embodiment of the consumable 24 shown in fig. 3, the substance 40 to be delivered in each discrete region 42 has the same composition as in each other discrete region 42. In alternative embodiments, the substances 40 to be delivered in at least two discrete regions 42 have compositions that are different from one another.
One or more perforations 46 extend through the support 28 and discrete portions of the aerosol-generating material 26. These perforations 46 are sized so that aerosol generated from one surface of the support can travel along the perforations to the other side of the support. This may help to obtain a mixture of aerosols before they leave the mouthpiece 16 when the user draws from the aerosol supply device 2. Perforations 46 may have a cross-sectional area of at least 0.01mm 2, at least 0.05mm 2, at least 0.1mm 2, at least 0.5mm 2, at least 1mm 2, at least 2mm 2, or at least 3mm 2.
The aerosol provision device 2 for use with the consumable 24 of fig. 2 has a heater 10, the heater 10 being comprised of one or more magnetic field generators (not shown). The distribution of the magnetic field generators in the heater 10 is such that each magnetic field generator will independently heat portions of the susceptor supporting discrete portions of the aerosol-generating material 26. This allows one or more discrete portions of the aerosol-generating material to be heated at a time. When the consumable 24 is placed in the heating chamber 8 via the heating chamber mouth 12, each discrete portion of aerosol-generating material 26 covers the magnetic field generator. The controller 20 determines which discrete portion or portions of the aerosol-generating material 26 are to be heated and causes the appropriate magnetic field generator or generators to generate a varying magnetic field. This causes one or more portions of the susceptor layer 34 that intersect those varying magnetic fields to be heated, which in turn heats one or more discrete portions of the aerosol-generating material 26.
As the or each discrete portion of aerosol-generating material 26 is heated, some of the heat generated in the susceptor layer 34 is conducted away from the susceptor layer 34 by the support layer 36 and into the adsorbent layer 38. This heat causes the volatile material 40 to aerosolize, the volatile material 40 being absorbed or adsorbed into the or each portion of the adsorbent layer 38 corresponding to the or each heated discrete portion of the aerosol-generating material 26.
In some embodiments, not shown, portions of the support layer 36 corresponding to discrete portions of the aerosol-generating material 26 may be modified to increase or decrease the thermal conductivity of those portions. This will increase or decrease the rate of heating of the adsorbent layer 38 and the temperature to which the adsorbent layer 38 is heated.
Referring to fig. 4 and 5, the consumable 124 is comprised of a support 128 with one or more discrete portions of the aerosol-generating material 26 supported on the support 128. The support 128 is a laminate having a first substrate/layer 34 and a second substrate/layer 36. The first layer 34 is a susceptor in the form of an aluminum foil layer.
Layer 36 of support 128 is a support layer and is present to give consumable 124 sufficient strength so that consumable 124 does not deform or bend during normal use. Layer 36 may be formed from card or plastic materials such as Polyetheretherketone (PEEK). It should be understood that layer 36 may comprise other materials.
Supported on the impermeable surface of the susceptor layer 34 are one or more discrete portions of aerosol-generating material 26 and an equal number of portions of adsorbent material 50. Each portion of the adsorbent material 50 has an annular form and each portion of the adsorbent material 50 is supported on the first surface 30 of the support 128 in a position such that it surrounds discrete portions of the aerosol-generating material 26 in the plane of the first surface of the support 128.
Each portion of the adsorbent material 50 includes at least one substance that is absorbed/adsorbed into the adsorbent material. The substance to be delivered that is absorbed/adsorbed into the adsorbent material may be different for one or more portions of the adsorbent material 50.
Consumable 124 is used in a similar manner to consumable 24 of fig. 2 and 3, except that the heating of portions of adsorbent material 50 is by direct conduction from susceptor 34 and/or discrete portions of aerosol-generating material 26.
Referring to fig. 6, the consumable 224 is comprised of a support 228 on which one or more discrete portions of the aerosol-generating material 26 are supported. The support 228 is a laminate having a first substrate/layer 34 and a second substrate/layer 36. The first layer 34 is a susceptor in the form of an aluminum foil layer.
Layer 36 of support 128 is a support layer and is present to give consumable 224 sufficient strength so that consumable 224 does not deform or bend during normal use. Layer 36 may be formed from card or plastic materials such as Polyetheretherketone (PEEK). It should be understood that layer 36 may comprise other materials.
Supported on the impermeable first surface 30 of the susceptor layer 34 are one or more discrete portions of the aerosol-generating material 26. One or more portions of the adsorbent material 150 are supported on the second surface 32 in locations corresponding to discrete portions of the aerosol-generating material 26 on the first surface 30. The number of portions of the adsorbent material 150 is equal to the number of discrete portions of the aerosol-generating material 26. Each portion of the adsorbent material 150 has the same shape as the discrete portions of the aerosol-generating material 26 and covers a larger area than the discrete portions of the aerosol-generating material 26.
Each portion of the adsorbent material 150 includes at least one substance that is absorbed/adsorbed into the adsorbent material. The substance to be delivered that is absorbed/adsorbed into at least a portion of the adsorbent material 110 may be different from other portions of the adsorbent material 150.
Consumable 224 is used in a similar manner to consumable 24 of fig. 2 and 3.
Referring to fig. 7, the consumable 324 is comprised of a support 328 on which one or more discrete portions of the aerosol-generating material 26 are supported. The support 328 is a laminate having a first substrate/layer 36 and a second substrate/layer 38. The first layer 36 of the support 328 is a support layer and is present to give the consumable 324 sufficient strength so that the consumable 324 does not deform or bend during normal use. Layer 36 may be formed from card or plastic materials such as Polyetheretherketone (PEEK). It should be understood that layer 36 may comprise other materials.
The second layer 38 of the support 328 is a layer of adsorbent material. The second layer 38 forms the first surface 30 of the support 328.
Supported on the adsorbent surface of the adsorbent layer 38 are one or more discrete portions of the aerosol-generating material 26. The sorbent layer 38 includes one or more discrete regions 342, the discrete regions 342 having boundaries 344 represented by lines. The number of discrete regions 342 is equal to the number of discrete portions of the aerosol-generating material 26, and each discrete region 342 surrounds a discrete portion of the aerosol-generating material 26 in the plane of the first surface of the support 328.
The boundary 344 is located at the interface of the sorbent material inside the discrete region 342 having the first absorbency/adsorbtion level (X) and the sorbent material outside the discrete region 342 having the second absorbency/adsorbtion level (Y), and X is greater than Y. The absorbency/adsorptivity level Y of the adsorbent material outside of the discrete regions 342 is a result of treatment to reduce its absorbency/adsorptivity level.
Each discrete region 342 includes at least one substance to be delivered that is absorbed/adsorbed into the adsorbent material of the discrete region. For one or more discrete regions 342, the substance to be delivered that is absorbed/adsorbed into the adsorbent material may be different relative to other discrete regions 342.
Consumable 324 is used in a similar manner to consumable 24 of fig. 2 and 3, except that the heating of consumable 324 is by a resistive heater. The resistive heater may comprise one or more separate heating zones, which may be heated one at a time, to allow individual discrete portions of the aerosol-generating material 26 to be heated.
In a further embodiment of the consumable 324 of fig. 7, not shown, the support may be a single piece of adsorbent material 38. The remaining details of this embodiment are the same as the embodiment of fig. 7.
Referring to fig. 8, consumable 424 is comprised of a support 428. One or more discrete portions of the aerosol-generating material 26 are supported on the first face 30 of the support 428. The support 428 is formed of an adsorbent material. Consumable 424 is adapted to be heated by an external heating source (not shown), such as a resistive heater that emits radiant heat.
The substance 40 to be delivered is absorbed or adsorbed into the second face 32 of the support 428 in regions of the second face 32 corresponding to discrete portions of the aerosol-generating material 26. One or more perforations 446 extend through the discrete portion of the aerosol-generating material 26, the support 428, and the substance 40 to be delivered.
Referring to fig. 9, an exemplary method of manufacturing a consumable is shown, wherein the method comprises the steps of:
A support 28 comprising a susceptor layer 34, a support layer 36, and a sorbent layer 38 is provided in step 60.
In step 62, a slurry of aerosol-generating material is provided, the slurry comprising a solvent for the aerosol-generating material and one or more desired active substances.
In step 64, a slurry of aerosol-generating material 26 is applied to one or more areas on the surfaces 30, 32 of the support 28.
In step 66, the applied slurry is dried to form a solid or gel of aerosol-generating material on the surface of the support. The drying process may be to allow the solvent for the aerosol-generating material to evaporate at ambient conditions. Or the drying process may be accelerated by heating the slurry to a temperature below the temperature at which the aerosol-generating material begins to aerosolize to promote evaporation of the solvent. Heating may be by conduction or radiant heating methods. Alternatively or additionally, step 66 may include exposing the aerosol-generating material to a high airflow through the aerosol-generating material to facilitate evaporation of the solvent from the aerosol-generating material.
Step 66 may include a drying technique that will cause some of the desired active ingredients to evaporate from the aerosol-generating material if present in the slurry of aerosol-generating material at a rate sufficient so that once drying is complete, the remaining aerosol-generating material will not include the active ingredients in the slurry amount.
Once step 66 is completed, a determination may be made at step 68 as to whether further application of the slurry of aerosol-generating material is required. If the answer to the question in step 68 is "yes", steps 64 to 68 are repeated. The second or subsequent application of the slurry may be the same slurry application as the first application or a slurry of a different composition than at least the first application.
Once the answer to the question in step 68 is "no," one or more substances 40 to be delivered are applied to the adsorbent material 38 in step 70. These substances to be delivered may have a high volatility. However, they are not subjected to the conditions of the drying step 66, and thus the amount of material that needs to be applied to the adsorbent region may be much less than if they were subjected to the drying step 66. The substance to be delivered is applied to the surface of the adsorbent material 38 and then absorbed or adsorbed into the adsorbent material 38.
At step 72, at least the support 28 is perforated by the perforation means.
In step 74, the support is cut into two or more individual consumables that are ready for use or packaging and distribution to the user.
Referring to fig. 10, a second exemplary method of manufacturing a consumable is shown, wherein the method comprises the following steps. Steps identical to those in the method of fig. 7 have the same reference numerals and are not described again below.
The support 28 including the support layer 36 is provided in step 76.
Steps 62 to 68 are as in the manufacturing method of fig. 9.
Once the answer to the question in step 68 is no, one or more portions of the adsorbent material 50, 150 are secured to the support 28 in step 78. The sorbent material may be applied to a preformed support and wherein one or more substances 40 to be delivered have been absorbed/adsorbed into the sorbent material portions 50, 150. Or after the portion of the sorbent material 50, 150 is secured to the support, the portion of the sorbent material 50, 150 may have a substance to be delivered applied to the portion of the sorbent material 50, 150. In this alternative, the substance to be delivered is then allowed to be absorbed or adsorbed.
Step 78 is followed by steps 72 and 74.
Referring to fig. 11, a third exemplary method of manufacturing a consumable is shown, wherein the method comprises the following steps. Steps identical to those in the method of fig. 9 or 10 have the same reference numerals and are not described below.
Step 76 is followed by steps 62 and 64.
In step 80, it is determined whether a paste that dries to form the adsorbent material 50, 150 is applied to the support 28.
If the answer to step 80 is "yes", the paste is provided and applied to the support in step 82. The process then proceeds to a drying step 66.
If the answer to step 80 is "no," the process proceeds to a drying step 66.
Then steps 68, 70, 72 and 74 follow.
Consumer products as a result of the present disclosure have been found to have advantageous storage characteristics because the substance to be delivered has been found to maintain a substantially consistent flavor profile for at least 90 days after consumer product manufacture.
The long-term flavor profile of the material to be delivered in the form of a citrus flavor composition was investigated. In testing, a consumer product comprising a card support covered with a layer of aluminum foil was manufactured. A layer of aerosol-generating material (consisting of a binder and an aerosol-former (glycerin)) is applied on the face of the support formed by the aluminum layer and the aerosol-generating material is solidified. Once the aerosol-generating material has solidified, 0.34mg of the citrus flavour composition is applied to the face of the consumer product formed from the card using a pipette, in a position corresponding to the predetermined heating zone. The consumable will be heated in the predetermined heating zone.
The samples were subjectively evaluated five time periods (T) after application of the citrus flavor composition to the consumer product.
For evaluation during time period T, the following procedure was followed:
two days prior to time period T, control samples were prepared using the same techniques and supports as the test samples were prepared.
During time period T, one of the predetermined heating zones on the test consumable is heated using an aerosol provision device comprising a heater, a chamber in which an aerosol is formed when heated, and a mouthpiece. The test person then performs a sensory evaluation of the aerosol received from the mouthpiece. After cleaning the aerosol supply device, this operation was repeated for the control sample.
The evaluation results are shown in the following table 1:
/>
as can be seen from table 1, there was little loss of flavoring in the 90 day study.
Consumer studies of the response to various flavors were performed as indicated in table 2 below.
The sample was then heated as above and the aerosol generated was sampled by the tester. These flavors were found to be cleaner tasting than cigarettes and did not include any ashes or burnt tastes (note).
The test person also found that the level of aerosol/particulate matter seen when the inhaled aerosol was exhaled was below the level experienced with the cigarette and that little or no aroma was left in the test chamber after testing.
