Description

Aerosol-generating composition comprising nicotine and acid or nicotine salt

The present invention relates to aerosol-generating compositions comprising an aerosol-generating material; Consumables for use within a non-flammable aerosol delivery system, the consumables comprising an aerosol generating composition; and non-flammable aerosol delivery systems.

Smoking articles such as cigarettes, cigars, etc. produce tobacco smoke by burning tobacco during use. Alternatives to these types of articles release the compounds from the substrate material by heating rather than burning, thereby releasing an inhalable aerosol or vapor. These may be referred to as non-flammable smoking articles, aerosol generating assemblies or non-flammable aerosol delivery systems.

One example of such a product is a heating device, which releases compounds by heating but not burning aerosolizable solid materials. This aerosolizable solid material may, in some cases, contain tobacco material. Heating volatilizes at least one component of the material, typically forming an inhalable aerosol. These products may be referred to as non-combustible heating devices, tobacco heating devices or tobacco heating products (THP). Various other arrangements are known for volatilizing at least one component of an aerosolizable solid material.

Another example is e-cigarette/cigarette heating product hybrid devices, also known as electronic cigarette hybrid devices. These hybrid devices have a liquid source (which may or may not contain nicotine) that is vaporized by heating to generate an inhalable vapor or aerosol. The device further contains an aerosolizable solid material (which may or may not contain tobacco material) whose components are entrained in an inhalable vapor or aerosol to generate an inhalation medium.

Various colorants may be used depending on the desired color of the aerosol generating material. The color of the aerosol-generating material may be, for example, white, green, red, purple, blue, brown or black. Other colors are also envisioned. Natural or synthetic colorants may be used, such as natural or synthetic dyes, food-grade colorants, and pharmaceutical-grade colorants. In certain embodiments, the colorant is caramel, which can impart the aerosol generating material with a brown appearance. In such embodiments, the color of the aerosol-generating material may be similar to the color of other components of the aerosol-generating composition comprising the aerosol-generating material (e.g., tobacco materials). In some embodiments, the addition of a colorant to the aerosol-generating material renders the aerosol-generating material visually indistinguishable from other components of the aerosol-generating composition.

The colorant can be incorporated during forming the aerosol-generating material (e.g., when forming a slurry comprising the materials forming the aerosol-generating material) or while forming the aerosol-generating material (e.g., by spraying onto the aerosol-generating material). It may later be applied to aerosol-generating materials.

other functional materials

One or more other functional ingredients may include one or more of pH adjusters, preservatives, stabilizers, and/or antioxidants.

In some embodiments, the aerosol-generating material is formed as a sheet. In some cases, the aerosol generating material may be incorporated into a non-flammable aerosol delivery system or consumable in sheet form. Sheets of aerosol-generating material may be flat sheets, gathered or bundled sheets, crimped sheets, or rolled sheets (i.e. in the form of tubes) or strips (e.g., cutting the sheet into longitudinal strips). formed by doing so) can be integrated. In some such cases, the aerosol-generating material of these embodiments may be included in the system/consumable as a sheet, such as a sheet surrounding a rod of aerosol-capable material (eg, tobacco). For example, a sheet of aerosol-generating material can be formed on a wrapping paper surrounding an aerosol-enabled material, such as a cigarette. In other cases, the sheet may be shredded and then incorporated into the assembly, suitably mixed into an aerosol-enabled material such as cut rag tobacco.

In some cases, the aerosol-generating material may be in the form of a sheet or layer having a thickness of about 0.015 mm to about 1.0 mm. Suitably, the thickness may range from about 0.05 mm, 0.1 mm or 0.15 mm to about 0.5 mm or 0.3 mm, for example 0.1 to 3 mm or 0.15 to 3 mm. Materials with a thickness of 0.2 mm may be particularly suitable. The aerosol-generating material may include more than one layer, and the thickness described herein refers to the collective thickness of these layers.

If the aerosol-generating material is too thick, heating efficiency may be impaired. This adversely affects power consumption during use. Conversely, if the aerosol generating material solid is too thin, it is difficult to manufacture and handle; Very thin materials are difficult to cast and brittle, which can adversely affect aerosol formation when used.

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 can have a tensile strength of about 200 N/m to about 2000 N/m. In some examples, the aerosol-generating material in sheet form can have a tensile strength of about 200 N/m to about 900 N/m. In some instances, such as when the aerosol-generating material does not include a filler, the aerosol-generating material has a force of about 200 N/m to about 400 N/m, or about 200 N/m to about 300 N/m, or about 250 N/m. It can have a tensile strength of m. These tensile strengths may be particularly suitable for embodiments where the aerosol-generating material and/or aerosol-generating composition is formed into a sheet and then shredded and incorporated into the consumable. In some instances, such as when the aerosol-generating material includes a filler, the aerosol-generating material has a weight of between about 600 N/m and about 900 N/m, or between about 700 N/m and about 900 N/m, or about 800 N/m. It can have a tensile strength of These tensile strengths may be particularly suitable for embodiments in which the aerosol-generating material and/or aerosol-generating composition are included in the article/non-flammable aerosol delivery system as rolled sheets, suitably in the form of a tube.

The aerosol-generating composition comprising the aerosol-generating material may have any suitable areal density, such as from 30 g/m2 to 120 g/m2. In some cases, the aerosol-generating material has a density similar to cut rag tobacco, and such that mixtures of such materials do not readily separate) from 80 to 120 g/m2, or from about 70 to 110 g/m2. It may have a mass per unit area of g/m2, or in particular about 90 to 110 g/m2, or suitably about 100 g/m2. These areal densities may be particularly suitable when the aerosol-generating composition is included in a consumable/system when assembled in sheet form or as shredded sheets (discussed further below). In some cases, the aerosol-generating composition can have a mass per unit area of about 30 to 70 g/m2, 40 to 60 g/m2, or 25 to 60 g/m2 and can be used to wrap an aerosol-enabled material such as a cigarette. there is.

In some embodiments, the aerosol-generating material is formed as a film on a support. The aerosol-generating membrane may be a continuous membrane or a discontinuous membrane, such as an arrangement of individual portions of the membrane on a support. In some cases, the aerosol-generating membrane does not include filler.

Aerosol-generating materials for use in aerosol generation can be present on or within a support to form a substrate. The support may be or include, for example, paper, card, paperboard, cardboard, reconstituted material, plastic material, ceramic material, composite material, glass, metal, or metal alloy. You can. In some embodiments, the support includes (or is) a susceptor. In some embodiments, the susceptor is an aluminum sheet. 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.

The aerosol-generating composition may include a carrier on which the aerosol-generating material is provided. The carrier functions as a support on which the aerosol generating material is layered, facilitating manufacturing. The carrier may provide tensile strength to the aerosol generating material layer, facilitating handling.

In some cases, the carrier may be formed of materials selected from metal foil, paper, carbon paper, oil-resistant paper, ceramics, carbon allotropes such as graphite and graphene, plastic, cardboard, wood or combinations thereof. . In some cases, the carrier may include or be comprised of tobacco material, such as a sheet of reconstituted tobacco. In some cases, the carrier may be formed from materials selected from metal foil, paper, cardboard, wood, or combinations thereof. In some cases, the carrier itself may be a laminate structure comprising layers of materials selected from the previous lists. In some cases, the carrier may also function as a flavor carrier. For example, the carrier may be impregnated with flavoring agent or tobacco extract.

In some cases, the carrier may be magnetic. This functionality can be used to fasten the carrier to a non-flammable aerosol presentation device in use or can be used to create specific aerosol generating material shapes. In some cases, the aerosol-generating composition may include one or more magnets that can be used to fasten the material to the induction heater when in use.

In some cases, the carrier may be substantially or entirely impermeable to gases and/or aerosols. This prevents aerosols or gases from passing through the carrier layer, thereby controlling the flow and ensuring delivery to the user. It may also be used to prevent condensation or other deposition of gases/aerosols in use, for example on the surface of a heater provided in an aerosol generating assembly. Accordingly, consumption efficiency and hygiene may be improved in some cases.

In some cases, the surface of the carrier that engages the aerosol-generating material may be porous. For example, in one case, the carrier includes paper. Porous carriers such as paper have been found to be particularly suitable; The porous (eg, paper) layer is adjacent to the aerosol-generating material layer to form a strong bond. The aerosol-generating material may be formed by drying a gel, without being limited by theory, such that the slurry forming the gel partially impregnates a porous carrier (e.g., paper), such that when the gel hardens, the carrier adheres to the gel. It is thought to be partially combined. This provides a strong bond between the gel and the carrier (and between the dried gel and the carrier).

In some embodiments, the aerosol generating material may be laminated to the carrier as a paper sheet.

In some embodiments, when the aerosol-generating material is formed from a slurry as described herein, the slurry layer may be formed on a carrier, such as a paper sheet.

Additionally, surface roughness can contribute to the bond strength between the aerosol-generating material and the carrier. The paper roughness (relative to the surface in contact with the carrier) is suitably 50 to 1000 Bekk sec, suitably 50 to 150 Bekk sec, suitably 100 Bekk sec (over an atmospheric pressure interval of 50.66 to 48.00 kPa). was found to be in the range of (Beck Smoothness Tester is an instrument used to determine the smoothness of a paper surface where a specified pressure of air leaks between a smooth glass surface and a paper sample; the time (in seconds) it takes for a fixed volume of air to seep between these surfaces is called "Beck Smoothness") "lim)

Conversely, the surface of the carrier facing away from the aerosol-generating material can be arranged to contact the heater, with a smoother surface providing more efficient heat transfer. Accordingly, in some cases, the carrier is arranged to have a rougher side facing the aerosol-generating material and a smoother side facing away from the aerosol-generating material.

In one particular case, the carrier may be a paper-backed foil; The paper layer is brought into contact with the aerosol generating material layer and the properties discussed in the previous paragraphs are provided by this contact. The foil backing is substantially impermeable and provides control of the aerosol flow path. The metal foil backing can also serve to conduct heat to the aerosol generating material.

In other cases, the foil layer of the paper-backed foil abuts the aerosol generating material. The foil is substantially impermeable, thereby preventing water provided to the aerosol-generating material from being absorbed into the paper, which could weaken its structural integrity.

In some cases, the carrier is formed of or includes a metal foil, such as aluminum foil. Metal carriers may allow better conduction of thermal energy to the aerosol generating material. Additionally or alternatively, the metal foil can function as a susceptor in an induction heating system. In certain embodiments, the carrier includes a metal foil layer and a support layer such as cardboard. In these embodiments, the metal foil layer may have a thickness of less than 20 μm, such as about 1 μm to about 10 μm, suitably about 5 μm.

In some cases, the carrier may have a thickness of about 0.010 mm to about 2.0 mm, suitably about 0.015 mm, 0.02 mm, 0.05 mm, or 0.1 mm to about 1.5 mm, 1.0 mm, or 0.5 mm.

In some embodiments, the present disclosure relates to consumables comprising an aerosol generating composition and configured for use with non-flammable aerosol presentation devices. These consumables are sometimes referred to as articles throughout this disclosure.

The consumables may be used with any suitable non-flammable aerosol delivery device.

A consumable is an article that includes or consists of an aerosol-generating composition, some or all of which is intended to be consumed during use by a user.

The consumable may include one or more other components, such as an aerosol-generating composition storage region, an aerosol-generating composition delivery component, an aerosol-generating region, a housing, a wrapper, a mouthpiece, a filter, and/or an aerosol modifier. The consumable may also include an aerosol generator, such as a heater, that emits heat to cause the aerosol generating composition to generate an aerosol upon use. The heater may comprise, for example, a combustible material, a material heatable by electrical conduction, or a susceptor.

In some embodiments, the consumable includes a single aerosol-generating composition. That is, the consumable includes an aerosol-generating composition as defined herein and does not include other aerosol-generating ingredient(s), active agent(s), agent(s) or composition(s).

In some embodiments, the consumables are substantially free of tobacco. “Substantially free” means that the material contains less than 1% by weight tobacco, such as less than 0.5% by weight tobacco. In some embodiments, the consumable is cigarette-free. In some embodiments, the consumable product does not include tobacco fibers.

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. The heating material may be a magnetic material, such that 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 mechanisms. A device configured to generate a changing magnetic field is referred to herein as a magnetic field generator.

Aerosol modifiers are substances, typically located downstream of the aerosol generating area, that are configured to modify the produced aerosol, for example by altering the taste, flavor, acidity or other properties of the aerosol. The aerosol modifier may be provided in an aerosol modifier release component operable to selectively release the aerosol modifier.

Aerosol modifiers may be, for example, additives or adsorbents. Aerosol modifiers may include, for example, one or more of flavorants, colorants, water, and carbon adsorbents. Aerosol modifiers may be solid, liquid or gel, for example. Aerosol modifiers may be in powder, thread or granular form. The aerosol modifier may be free of filtration material.

An aerosol generator is a device configured to produce an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol-generating material to release one or more volatile substances from the aerosol-generating composition to form an aerosol. In some embodiments, an aerosol generator is configured to generate an aerosol from an aerosol-generating composition without heating. For example, an aerosol generator can be configured to apply one or more of vibration, increased pressure, or electrostatic energy to the aerosol generating composition.

Non-flammable aerosol delivery system

According to another aspect of the disclosure, a non-flammable aerosol delivery system is provided comprising the consumables described herein and a non-flammable aerosol delivery device.

According to the present disclosure, a "non-combustible" aerosol delivery system comprises a component aerosol generating material of the aerosol delivery system (or a component thereof) to facilitate delivery of at least one substance to a user. It is a system that neither combusts nor burns.

In some embodiments, the delivery system is a non-flammable aerosol delivery system, such as a powered non-flammable aerosol delivery system.

In some embodiments, the non-flammable aerosol provision system is an aerosol generating material heating system, also known as a heat-not-burn system. One example of such a system is a tobacco heating system.

In some embodiments, the non-flammable aerosol delivery device is a heat-not-burn device.

In some embodiments, the non-flammable aerosol delivery system is a hybrid system that generates an aerosol using a combination of aerosol generating materials, one or more of which may be heated. In some embodiments, a hybrid system includes an aerosol-generating material described herein comprising or consisting of an aerosol-generating material and an additional liquid or gel aerosol-generating material.

In some embodiments, the non-flammable aerosol delivery device is an electronic cigarette hybrid device.

Typically, a non-flammable aerosol delivery system may include a non-flammable aerosol delivery device and consumables for use with the non-flammable aerosol delivery device.

In some embodiments, a non-flammable aerosol delivery system, such as a non-flammable aerosol delivery device thereof, can include a power source and a controller. The power source may be, for example, an electric power source or an exothermic power source. In some embodiments, the heating power source includes a carbon substrate capable of supplying energy to distribute power in the form of heat to an aerosol generating material or heat transfer material proximate to the heating power source.

In some embodiments, a non-flammable aerosol delivery system, such as a non-flammable aerosol delivery device thereof, may include a region for receiving consumables, an aerosol generator, an aerosol generation region, a housing, a mouthpiece, a filter, and/or an aerosol modifier.

A non-flammable aerosol delivery system or device can include a heater configured to heat but not combust the aerosol generating substrate. The heater may in some cases be a thin film, electrically resistive heater. In other cases, the heater may include an induction heater, etc. Also in further cases, the heater may be a combustible heat source or a chemical heat source that undergoes an exothermic reaction to generate heat when used.

In some cases, the heater can heat the aerosol-enabled material(s) without burning them from 120° C. to 350° C. when in use. In some cases, the heater can heat the aerosol-enabled material(s) to 140° C. to 250° C. without burning when in use. In some cases, when in use, substantially all of the aerosol-generating material is less than about 4 mm, 3 mm, 2 mm, or 1 mm from the heater. In some cases, the solid is positioned about 0.017 mm to 2.0 mm, suitably about 0.1 mm to 1.0 mm from the heater. These minimum distances may, in some cases, reflect the thickness of the carrier supporting the aerosol-generating material. In some cases, the surface of the aerosol generating material may directly contact the heater.

In some cases, a heater may be built into the aerosol-generating material. In some such cases, the heater may be an electrically resistive heater (including exposed contacts for connection to an electrical circuit). In such other cases, the heater may be a susceptor embedded in an aerosol-generating material that is heated by induction.

Non-flammable aerosol delivery systems may further include cooling elements and/or filters. The cooling element (if present) may serve or function to cool the gaseous or aerosol components. In some cases, the cooling element may serve to cool the gas components such that they condense to form an aerosol. The cooling element may also serve to keep very hot parts of the device away from the user. The filter (if present) may include any suitable filter known in the art, such as a cellulose acetate plug.

In some cases, the non-flammable aerosol delivery system may be a heat-not-burn system. That is, it can hold solid materials (and aerosol-capable materials without liquid). A non-combustion heating device is disclosed in WO 2015/062983 A2, incorporated by reference in its entirety.

In some cases, a non-flammable aerosol delivery system may include an electronic cigarette hybrid device. That is, it can hold solid aerosol-capable materials and liquid aerosol-capable materials. The separate aerosolizable materials can be heated by separate heaters, the same heater, or in one case, the downstream aerosolizable material can be heated by the hot aerosol generated from the upstream aerosolizable material. An electronic cigarette hybrid device is disclosed in WO 2016/135331 A1, which is incorporated by reference in its entirety.

Alternatively, consumables may be referred to herein as cartridges. The consumables may be configured for use in a THP, electronic cigarette hybrid device, or other aerosol generating device. In some cases, the consumable may further include a filter and/or cooling element, as previously described. In some cases, the consumable may be surrounded by wrapping material, such as paper.

The consumable may additionally include ventilation apertures. These may be provided on the side walls of the article. In some cases, ventilation apertures may be provided in the filter and/or cooling element. These apertures may allow cooling air to be drawn into the article during use, which may mix with heated volatile components thereby cooling the aerosol.

Aeration enhances the production of visible heated volatilized components from the article when the article is heated in use. The heated volatilized components become visible by a process of cooling the heated volatilized components such that supersaturation of the heated volatilized components occurs. The heated volatilized components are then subjected to droplet formation - otherwise known as nucleation - and eventually the size of the aerosol particles of the heated volatilized components decreases. It increases by further condensation of the heated components and coagulation of newly formed droplets from the heated volatilized components.

In some cases, the ratio of cooling air to the sum of cooling air and heated volatilized components (known as aeration ratio) is at least 15%. An aeration ratio of 15% allows heated volatilized components to be visualized by the method described above. The visibility of the heated volatilized ingredients allows the user to identify that the volatilized ingredients have been produced and adds to the sensory experience of the smoking experience.

In another example, the aeration ratio is 50% to 85% to provide additional cooling to the heated volatilized components. In some cases, the aeration ratio may be at least 60% or 65%.

1 and 2, a partial cutaway cross-sectional and perspective view of an example of consumable product 101 (“article”) is shown. Article 101 is configured for use with a device having a power source and heater. The article 101 of this embodiment is particularly suitable for use with the device 1 shown in Figures 5 to 7, described below. In use, the article 101 can be removably inserted into the device shown in FIG. 5 at the insertion point 20 of the device 1 .

One example article 101 is in the form of a substantially cylindrical rod comprising a rod-shaped filter assembly 105 and a body of the aerosol-generating composition 103. Aerosol-generating materials include aerosol-generating materials described herein. In some embodiments, the aerosol generating material may be included in sheet form. In some embodiments, the aerosol generating material may be included in the form of shredded sheets. In some embodiments, the aerosol-generating materials described herein may be incorporated in sheet form and shredded form.

Filter assembly 105 has three segments; It includes a cooling segment (107), a filter segment (109) and a mouth end segment (111). The article 101 has a first end 113, also known as the mouth end or proximal end, and a second end 115, also known as the distal end. The body of the aerosol-generating composition 103 is positioned toward the distal end 115 of the article 101. In one example, the cooling segment 107 is positioned adjacent the body of the aerosol-generating composition 103 between the body of the aerosol-generating composition 103 and the filter segment 109 such that the cooling segment 107 is positioned adjacent to the body of the aerosol-generating composition 103. It is in an abutting relationship with the composition 103 and the filter segment 109. In other examples, there may be a gap between the body of the aerosol-generating composition 103 and the cooling segment 107 and between the body of the aerosol-generating composition 103 and the filter segment 109. Filter segment 109 is positioned between cooling segment 107 and mouth end segment 111. Mouth end segment 111 is positioned toward proximal end 113 of article 101 adjacent filter segment 109. In one example, filter segment 109 is in abutting relationship with mouth end segment 111. In one embodiment, the overall length of filter assembly 105 is between 37 mm and 45 mm, and more preferably, the overall length of filter assembly 105 is 41 mm.

In one example, the rod of aerosol-generating composition 103 is 34 mm to 50 mm in length, suitably 38 mm to 46 mm in length, and suitably 42 mm in length.

In one example, the overall length of article 101 is between 71 mm and 95 mm, suitably between 79 mm and 87 mm, suitably around 83 mm.

The axial end of the body of the aerosol-generating composition 103 is visible at the distal end 115 of the article 101. However, in other embodiments, the distal end 115 of the article 101 may include an end member (not shown) that covers the axial end of the body of the aerosol-generating composition 103.

The body of the aerosol-generating composition 103 is coupled to the filter assembly 105 by an annular tipping paper (not shown), the tipping paper substantially surrounding the filter assembly 105 ( It is located around the circumference of the aerosol-generating composition (105) and extends partially along the length of the body of the aerosol-generating composition (103). In one example, the tipping paper is made from 58GSM standard tipping base paper. In one example, the tipping paper has a length between 42 mm and 50 mm, suitably about 46 mm.

In one example, cooling segment 107 is an annular tube, positioned around an air gap and defining the air gap within the cooling segment. The voids provide a chamber through which heated and volatilized components generated from the body of the aerosol-generating composition 103 flow. The cooling segment 107 is hollow to provide a chamber for aerosol accumulation, but is capable of absorbing axial compressive forces and bending moments that may occur during manufacturing and while the article 101 is being inserted into the device 1 in use. It has sufficient rigidity to withstand. In one example, the wall thickness of cooling segment 107 is approximately 0.29 mm.

Cooling segment 107 provides physical displacement between aerosol generating composition 103 and filter segment 109. The physical displacement provided by cooling segment 107 will provide a thermal gradient over the length of cooling segment 107. In one example, the cooling segment 107 has a temperature of at least 40° C. between the heated volatilized component entering the first end of the cooling segment 107 and the heated volatilized component exiting the second end of the cooling segment 107. It is configured to provide a temperature difference of In one example, the cooling segment 107 has a temperature of at least 60° C. between the heated volatilized component entering the first end of the cooling segment 107 and the heated volatilized component exiting the second end of the cooling segment 107. It is configured to provide a temperature difference of This temperature difference over the length of the cooling element 107 protects the temperature sensitive filter segment 109 from high temperatures of the aerosol-generating composition 103 when the aerosol-generating composition 103 is heated by the device 1 . If no physical displacement is provided between the filter segment 109 and the body of the aerosol-generating composition 103 and the heating elements of the device 1, the temperature sensitive filter segment 109 will be damaged during use, and so the It will not be able to perform the required functions effectively.

In one example, the length of cooling segment 107 is at least 15 mm. In one example, the length of the cooling segment 107 is 20 mm to 30 mm, more particularly 23 mm to 27 mm, more particularly 25 mm to 27 mm, suitably 25 mm.

The cooling segment 107 may be made of paper, provided that the cooling segment 107 is composed of a material that does not produce compounds of interest, for example toxic compounds, when the cooling segment 107 is in use adjacent to the heater of the device 1. means that In one example, the cooling segment 107 is made from a spirally wound paper tube that provides a hollow internal chamber but maintains mechanical rigidity. Helically wound paper tubes can meet the stringent dimensional accuracy requirements of high-speed manufacturing processes with respect to tube length, outer diameter, roundness and straightness.

In another example, cooling segment 107 is a recess created from stiff plug wrap or tipping paper. The rigid plug wrap or tipping paper is manufactured with sufficient rigidity to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article 101 is being inserted into the device 1 in use.

Filter segment 109 may be formed of any filter material sufficient to remove one or more volatilized compounds from the heated volatilized components from the aerosol generating material. In one example, filter segment 109 is made from a mono-acetate material, such as cellulose acetate. Filter segment 109 provides cooling and irritation-reduction from heated volatilized components without depleting the amount of heated volatilized components to levels unsatisfactory to the user.

In some embodiments, a capsule (not shown) may be provided in the filter segment 109. This may be positioned substantially in the center of the filter segment 109 over the filter segment 109 diameter and along the length of the filter segment 109 . In other cases, one or more dimensions may be offset. The capsule, if present, may in some cases retain volatile ingredients such as flavor or aerosol former materials.

The density of the cellulose acetate tow material of the filter segment 109 controls the pressure drop across the filter segment 109, which in turn controls the draw resistance of the article 101. Accordingly, material selection of the filter segment 109 is important in controlling the resistance to attraction of the article 101. Additionally, the filter segments perform a filtration function in the article 101.

In one example, the filter segment 109 is made of grade 8Y15 filter tow material, which provides a filtration effect on the heated volatilized material while reducing the size of condensed aerosol droplets resulting from the heated volatilized material. .

The presence of the filter segment 109 provides an insulating effect by providing additional cooling to the heated volatilized components exiting the cooling segment 107. This additional cooling effect reduces the contact temperature of the user's lips on the surface of the filter segment 109.

In one example, filter segment 109 is between 6 mm and 10 mm in length, more suitably about 8 mm.

Mouth end segment 111 is an annular tube located circumferentially and defining a void within mouth end segment 111 . The voids provide a chamber for heated volatilized components flowing from the filter segment 109. The mouth end segment 111 is hollow to provide a chamber for aerosol accumulation, but to withstand axial compressive forces and bending moments that may occur during manufacturing and while the article is being inserted into the device 1 in use. Has sufficient rigidity. In one example, the wall thickness of mouth end segment 111 is approximately 0.29 mm. In one example, the length of the mouth end segment 111 is between 6 mm and 10 mm, suitably about 8 mm.

The mouth end segment 111 can be manufactured from a helically wound paper tube that provides a hollow inner chamber but maintains critical mechanical rigidity. The helically wound paper tubes have It can meet the stringent dimensional accuracy requirements of high-speed manufacturing processes.

The mouth end segment 111 provides the function of preventing any liquid condensation accumulated at the outlet of the filter segment 109 from coming into direct contact with the user.

In one example, mouth end segment 111 and cooling segment 107 may be formed of a single tube, with filter segment 109 located within that tube separating mouth end segment 111 and cooling segment 107. It must be understood that

3 and 4, a partial cutaway cross-sectional view and perspective view of an example of article 301 are shown. The reference signs shown in FIGS. 3 and 4 are the same as the reference signs shown in FIGS. 1 and 2 but are increased by 200.

In the example of article 301 shown in FIGS. 3 and 4 , a ventilation zone 317 is provided in article 301 to allow air to flow from the exterior of article 301 to the interior of article 301. . In one example, ventilation zone 317 takes the form of one or more ventilation holes 317 formed through the outer layer of article 301. Ventilation holes may be located in the cooling segment 307 to assist in cooling the article 301. In one example, the ventilation zone 317 includes one or more rows of holes, preferably each row of holes having an article (301) in a cross-section substantially perpendicular to the longitudinal axis of the article (301). 301) They are arranged in a circumferential direction around the perimeter.

In one example, there are between one and four rows of vent holes to provide ventilation for the article 301. Each row of ventilation holes may have 12 to 36 ventilation holes 317. The ventilation holes 317 may have a diameter of, for example, 100 to 500 μm. In one example, the axial separation between the rows of ventilation holes 317 is between 0.25 mm and 0.75 mm, preferably 0.5 mm.

In one example, the ventilation holes 317 are uniform in size. In another example, the vent holes 317 vary in size. The vent holes may be manufactured using any suitable technique, for example, one or more of the following techniques: laser technology, mechanical drilling of the cooling segment 307, or allowing the cooling segment 307 to be inserted into the article 301. Pre-drilling of cooling segments 307 prior to formation. Ventilation holes 317 are positioned to provide effective cooling to article 301.

In one example, the rows of vent holes 317 are located at least 11 mm from the proximal end 313 of the article, suitably the vent holes are between 17 mm and 20 mm from the proximal end 313 of the article 301. is located in The positions of the ventilation holes 317 are positioned so that the user does not block the ventilation holes 317 when the article 301 is used.

Providing rows of ventilation holes 17 mm to 20 mm from the proximal end 313 of the article 301 allows the article 301 to be fully inserted into the device 1, as can be seen in FIGS. 6 and 7 . When done, the ventilation holes 317 can be located on the outside of the device 1. By locating the vent holes on the outside of the device, unheated air can enter the article 301 from the outside of the device 1 through the vent holes and help cool the article 301.

The length of the cooling segment 307 is such that when the article 301 is fully inserted into the device 1 , the cooling segment 307 is partially inserted into the device 1 . The length of the cooling segment 307 has the first function of providing a physical gap between the heater arrangement of device 1 and the thermally sensitive filter arrangement 309, with vent holes 317 located in the cooling segment, It also provides a second function that allows the article 301 to be positioned on the outside of the device 51 when fully inserted into the device 1 . As can be seen in FIGS. 6 and 7 , most of the cooling elements 307 are located within device 1 . However, there is a portion of the cooling element 307 that extends outside the device 1 . It is this part of the cooling element 307 that extends out of the device 1 where the ventilation holes 317 are located.

Referring now in more detail to Figures 5-7, a device arranged to heat an aerosol-generating composition to volatilize at least one component of the aerosol-generating material, typically to form an aerosol that can be inhaled. An example of (1) is shown. Device 1 is a heating device, which releases compounds by heating the aerosol-generating material without burning it.

The first end 3 is sometimes referred to herein as the mouth or proximal end 3 of the device 1 and the second end 5 is sometimes referred to herein as the distal end 5 of the device 1 do. The device 1 has an on/off button 7 that allows the entire device 1 to be switched on and off as desired by the user.

Device 1 includes a housing 9 for positioning and protecting the various internal components of device 1. In the example shown, the housing 9 has a top panel 17 generally defining the 'top' of the device 1 and a top panel 17 generally defining the 'bottom' of the device 1. It comprises a uni-body sleeve (11) surrounding the perimeter of the device (1) capped by a bottom panel (19). In another example, the housing includes, in addition to top panel 17 and bottom panel 19, a front panel, a rear panel, and a pair of opposing side panels.

The top panel 17 and/or the bottom panel 19 may be removably secured to the single-body sleeve 11 to allow easy access to the interior of the device 1, or the single-body sleeve 11 ) can be “permanently” fixed, for example, preventing the user from accessing the interior of the device 1. In one example, panels 17 and 19 are made of a plastic material, including glass-filled nylon formed, for example, by injection molding, and are formed into a single-body sleeve. (11) is manufactured from aluminum, although other materials and other manufacturing processes may be used.

The top panel 17 of the device 1 has an opening 20 at the mouth end 3 of the device 1 through which the article 101 containing the aerosol-generating material in use is exposed. , 301) can be inserted into and removed from the device 1 by the user.

The housing 9 positions or secures the heater arrangement 23, control circuitry 25 and power source 27 therein. In this example, heater arrangement 23, control circuitry 25, and power source 27 are positioned side by side, with control circuitry 25 generally positioned between heater arrangement 23 and power source 27. Although directionally adjacent (i.e., adjacent when viewed from one end), other positions are possible.

Control circuitry 25 may include a controller, such as a microprocessor arrangement, constructed and arranged to control heating of the aerosol-generating material within articles 101, 301, as discussed further below.

The power source 27 may be a battery, which may be, for example, a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium-ion batteries, nickel batteries (e.g., nickel-cadmium batteries), alkaline batteries and/or the like. Battery 27 is electrically connected to heater arrangement 23 to supply power as needed and heats the aerosol-generating material in the article under control of control circuitry 25 (as discussed, the aerosol-generating material Volatilizes aerosol-generating materials without burning them).

The advantage of locating power source 27 laterally adjacent to heater arrangement 23 is that a physically large power source 27 can be used without unduly lengthening device 1 overall. As will be understood, in general, a physically larger power source 27 has a greater capacity (i.e. the total electrical energy that can be supplied, often measured in Amp-hours, etc.) and therefore has a greater capacity for device 1. Battery life will be longer.

In one example, heater arrangement 23 is generally in the form of a hollow cylindrical tube having a hollow internal heating chamber, within which articles 101, 301 containing an aerosol-generating composition are stored. It is inserted for heating when in use. Different arrangements for the heater arrangement 23 are possible. For example, heater arrangement 23 may comprise a single heating element or may be formed of a plurality of heating elements aligned along the longitudinal axis of heater arrangement 23. The or each heating element may be annular or tubular, or at least partially-annular or partially-tubular, around its circumference. In one example, the or each heating element may be a thin film heater. In another example, the or each heating element may be made from a ceramic material. Examples of suitable ceramic materials include alumina and aluminum nitride and silicon nitride ceramics, which can be deposited and sintered. Other heating, including, for example, inductive heating, infrared heater elements that heat by emitting infrared radiation, or resistive heating elements formed, for example, by resistive electrical winding. Arrays are possible.

In one particular example, heater arrangement 23 is supported by a stainless steel support tube and includes a polyimide heating element. The heater arrangement 23 is such that when the article 101, 301 is inserted into the device 1, substantially the entire body of the aerosol-generating composition 103, 303 of the article 101, 301 is in the heater arrangement 23. ) The dimensions are determined to be inserted into the inside.

The or each heating element may be arranged such that selected zones of aerosol-generating material can be heated independently, eg sequentially (over time) or together (simultaneously), as desired.

In this example the heater arrangement 23 is surrounded along at least part of its length by a thermal insulator 31 . The insulation 31 helps reduce heat passing from the heater arrangement 23 to the outside of the device 1 . Insulation helps lower power requirements for heater arrangement 23 because it generally reduces heat loss. The insulation 31 also helps keep the exterior of the device 1 cool during operation of the heater arrangement 23 . In one example, the insulation 31 may be a double-walled sleeve that provides a low pressure zone between the two walls of the sleeve. That is, the insulation 31 may be, for example, a “vacuum” tube, i.e. a tube that is at least partially evacuated to minimize heat transfer by conduction and/or convection. Other arrangements for the insulation 31 are possible, including, for example, using insulating materials including suitable foam type materials in addition to or instead of a double wall sleeve.

The housing 9 may further comprise various internal support structures 37 to support the heating arrangement 23 as well as all internal components.

The device 1 has a collar 33 extending around the opening 20 and protruding from the opening 20 into the interior of the housing 9 and positioned between the collar 33 and one end of the vacuum sleeve 31. It further includes a generally tubular chamber 35. Chamber 35 further comprises cooling structures 35f, in this example spaced apart along the outer surface of chamber 35 and circumferentially around the outer surface of chamber 35. Each includes a plurality of arranged cooling fins (fins) 35f. When inserted into the device 1 over at least a portion of the length of the hollow chamber 35 , an air gap 36 exists between the hollow chamber 35 and the articles 101 , 301 . The void 36 is around the entire circumference of the article 101 , 301 over at least a portion of the cooling segment 307 .

The collar 33 is arranged circumferentially around the perimeter of the opening 20 and includes a plurality of ridges 60 protruding into the opening 20 . The ridges 60 are such that the open span of the opening 20 at the locations of the ridges 60 is smaller than the open span of the opening 20 at the locations without the ridges 60. Occupies space within the opening 20. Ridges 60 are configured to engage with articles 101 , 301 inserted into device 1 to assist in securing the device within device 1 . Open spaces (not shown in the figures) defined by adjacent pairs of ridges 60 and articles 101, 301 form ventilation paths around the exterior of articles 101, 301. These vent paths allow hot vapors escaping from the articles 101, 301 to exit the device 1 and cool air to exit the device 1 around the articles 101, 301 in the voids 36. Allow it to flow within.

In operation, the articles 101, 301 are removably inserted into the insertion point 20 of the device 1, as shown in FIGS. 5-7. In particular, referring to Figure 6, in one example:

The body of the aerosol-generating composition (103, 303) positioned towards the distal end (115, 315) of the article (101, 301) is completely contained within the heater arrangement (23) of device (1). The proximal ends 113, 313 of the articles 101, 301 extend from the device 1 and serve as a mouthpiece assembly for the user.

In operation, heater arrangement 23 will heat the article 101, 301 to volatilize at least one component of the aerosol-generating composition from the body of aerosol-generating material 103, 303.

The primary flow path for the heated volatilized components from the body of the aerosol-generating composition 103, 303 is axially, through the article 101, 301, and inside the cooling segment 107, 307. through the chamber, through the filter segments 109, 309, and through the mouse end segments 111, 311 to the user. In one example, the temperature of the heated volatilized components resulting from the body of the aerosol-generating material is between 60° C. and 250° C., which may exceed the inhalation temperature acceptable to the user. As the heated volatilized components move through the cooling segments 107, 307, they cool and some of the volatilized components will condense on the inner surfaces of the cooling segments 107, 307.

In the examples of article 301 shown in FIGS. 3 and 4 , cooling air may enter cooling segment 307 through vent holes 317 formed in cooling segment 307 . This cooling air will mix with the heated volatilized components and provide additional cooling to the heated volatilized components.

About 1 to about 30 weight percent nicotine salt;

About 45 to about 80 weight percent gelling agent;

About 10 to about 54 weight percent aerosol former material; and

optionally comprising a filler,

These weight percent values are calculated on a dry weight basis,

This method:

(a) providing a slurry comprising nicotine salt, gelling agent, aerosol former material, acid, solvent, and any optional additional ingredients of aerosol generating material;

(b) forming a layer of slurry;

(c) optionally curing or crosslinking the slurry layer; and

(d) drying the slurry to form an aerosol-generating material.

A further aspect of the invention provides a method of manufacturing a consumable product or system as described above. The method includes methods of manufacturing the aerosol-generating material and incorporating the aerosol-generating material into a consumable or system. The method includes (a) forming a slurry comprising components of an aerosol generating material or precursor thereof, (b) forming a slurry layer, and (c) optionally curing or crosslinking the slurry, (d) drying the aerosol-generating material, and (e) incorporating the resulting aerosol-generating material into a consumable or system.

In step (a), nicotine or nicotine salt is first dissolved in the aerosol former material and the resulting solution can be added to the other components of the slurry.

Forming the slurry layer in step b) of the method may include, for example, spraying, casting or extruding the slurry. In some cases, the layer is formed by electrospraying the slurry. In some cases, the layer is formed by casting the slurry.

In some cases, steps (b) and/or (c) and/or (d) may occur at least partially simultaneously (eg, during electrospraying). In some cases, these steps may occur sequentially.

In some cases, a curing agent or crosslinking agent (such as a calcium source) may be added to the slurry before or during step (b). This is suitable where gelation occurs relatively slowly (e.g. using alginate gelling agents), so that the slurry can be cast, for example after the hardener has been added.

In other cases, step (c) of curing or crosslinking the slurry may include adding a curing agent or crosslinking agent to the slurry layer. The curing agent or crosslinking agent can, for example, be sprayed onto the slurry or preloaded onto the surface on which the slurry is to be deposited.

For example, a curing agent or crosslinking agent comprising a calcium source (e.g., calcium chloride or calcium citrate) can be added to a slurry containing alginate and/or pectin to form a calcium crosslinked alginate/pectin gel. In some cases where gelation occurs quickly (for example, when using pectin gelling agents), calcium must be added after casting (since the slurry may be too viscous to cast).

The total amount of curing agents or crosslinking agents, such as calcium sources, may be 0.5 to 5% by weight (calculated on a dry weight basis). It has been found that adding too little curing agent or crosslinking agent can result in a gel that does not stabilize any optional flavor and results in the gel being flavorless. It has also been found that if too much hardener or cross-linker is added, the gel becomes very sticky or brittle and consequently has poor handling properties.

Alginate salts are derivatives of alginic acid and are typically high molecular weight polymers (10 to 600 kDa). Alginic acid is a copolymer of β-D-mannuronic acid (M) and α-L-guluronic acid (G) units (blocks) linked together with (1,4)-glycosidic bonds to form a polysaccharide. am. By adding calcium cations, the alginate crosslinks to form a gel. Alginate salts with high G monomer content can more easily form a gel upon addition of a calcium source. Accordingly, in some cases, the gel-precursor is an alginate wherein at least about 40%, 45%, 50%, 55%, 60% or 70% of the monomer units in the alginate copolymer are α-L-guluronic acid (G) units. May contain salt.

In some cases, the slurry may be warmed before and during casting. This can slow gelation, improve handling, and ease the casting process. Furthermore, warming the slurry may melt optional flavor ingredients (e.g., menthol) to facilitate handling.

In some cases, menthol or other optional flavors may be distributed through the slurry in powder form. In some cases, menthol or other flavors may be melted into the slurry (where it is warm). In these cases, an emulsifier such as acacia gum can be added to disperse the molten menthol in the slurry.

In some cases, the slurry may be cast onto a bandcast sheet. The sheet may be filled with a releasing agent, such as lecithin, which can aid in the separation of the bandcast and aerosol-generating material.

In another aspect, there is provided a slurry comprising:

About 1 to about 30% nicotine by weight;

About 15 to about 80 weight percent gelling agent;

About 10 to about 60 weight percent aerosol former material;
