DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] As used herein, the term "aerosol-generating material" is a material that can generate an aerosol when, for example, heated, irradiated, or energized in any other manner. The aerosol-generating material may be, for example, in the form of a solid, liquid, or gel that may or may not contain active substances and / or flavorings. The aerosol-generating material may include any plant-based material, such as a tobacco-containing material, and may include, for example, one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The aerosol-generating material may also include other non-tobacco products that may or may not contain nicotine depending on the product. The aerosol-generating material may be, for example, in the form of a solid, liquid, gel, wax, etc. The aerosol-generating material may also be, for example, a combination or mixture of materials. The aerosol-generating material may also be known as a "smokable material."

[0028] The aerosol-generating material may include a binder and an aerosol-forming agent. Optionally, an active agent and / or a filler may also be present. Optionally, a solvent, such as water, is also present, and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. In some embodiments, the aerosol-generating material is substantially free of plant material. In some embodiments, the aerosol-generating material is substantially free of tobacco.

[0029] An aerosol-generating material may include or be an "amorphous solid." An amorphous solid may be a "monolithic solid." In some embodiments, an amorphous solid may be a dry gel. An amorphous solid is a solid material that can hold some fluid therein, such as a liquid. In some embodiments, an aerosol-generating material may include, for example, about 50%, 60%, or 70% amorphous solid by weight, up to about 90%, 95%, or 100% amorphous solid by weight.

[0030] The aerosol-generating material may include an aerosol-generating film. The aerosol-generating film may include or be a sheet that may optionally be shredded to form a shredded sheet. The aerosol-generating sheet or shredded sheet may be substantially free of tobacco.

[0031] According to the present disclosure, a "non-combustion" aerosol delivery system is one in which the constituent aerosol-generating materials (or components thereof) of the aerosol delivery system are not combusted or burned to facilitate delivery of at least one substance to a user.

[0032] In some embodiments, the delivery system is a non-combustion aerosol delivery system, such as a powered non-combustion aerosol delivery system.

[0033] In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also known as a 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 a requirement.

[0034] In some embodiments, the non-combustion aerosol delivery system is an aerosol-generating material heating system, also known as a non-combustion heating system. One example of such a system is a tobacco heating system.

[0035] In some embodiments, the non-combustion 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. Each of the aerosol-generating materials may be, for example, in solid, liquid, or gel form and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product.

[0036] Typically, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and a consumable item for use with the non-combustion aerosol delivery device.

[0037] In some embodiments, the present disclosure relates to consumables that include aerosol-generating materials and are configured for use with non-combustion aerosol delivery devices. These consumables may be referred to as articles throughout this disclosure.

[0038] In some embodiments, the non-combustion aerosol delivery system, e.g., the non-combustion aerosol delivery device, may include a power source and a controller. The power source may be, for example, an electrical power source or a heat generating power source. In some embodiments, the heat generating power source includes a carbon substrate that can be energized to deliver power in the form of heat to an aerosol generating material or a heat transfer material proximate to the heat generating power source.

[0039] In some embodiments, the non-combustion aerosol delivery system may include an area for receiving a consumable, an aerosol generator, an aerosol-generating area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0040] In some embodiments, consumables for use with non-combustion aerosol delivery devices may include aerosol generating materials, aerosol generating material storage areas, aerosol generating material transfer components, aerosol generators, aerosol generating areas, housings, packaging materials, filters, mouthpieces, and / or aerosol modifiers.

[0041] The aerosol generating device can receive an article that includes an aerosol-generating material for heating. An "article" in this context is a component that includes or contains, in use, an aerosol-generating material that is heated to volatilize the aerosol-generating material, and optionally other components in use. A user may insert the article into the aerosol generating device before the article is heated to generate an aerosol, which the user then inhales. The article may be of a predetermined or specific size, for example, configured to be placed in a heating chamber of the device sized to receive the article.

[0042] FIG. 1 illustrates an example of an aerosol generating system 100. The system 100 includes an aerosol generating device 102 for generating an aerosol from an aerosol generating material, and a consumable item 105. The consumable item 105 includes an article 104 including an aerosol generating material, and a filter element 106 for filtering air passing through the article 104. The article 104 and the filter element 106 are separate elements. The article 104 functions as an aerosol generating element. The article 104 is replaceable. The filter element 106 is replaceable. Although described herein as a consumable item 105, it will be understood that the article 104 and the filter element 106 may be provided separately and may be replaceable separately. The filter element 106 may be replaceable after a different number of uses than the article 104. The filter element 106 is interchangeable with another filter element 106. The article 104 is interchangeable with another article 104. The filter element 106 protrudes from the device for receipt in a user's mouth. When the user is not using the article 104 as a mouthpiece, the article may be fully received in the device 102. In an embodiment, the article 104 protrudes from the device for ease of insertion and removal.

[0043] The device 102 is a non-combustion aerosol generating device 102. The device 102 can be used to heat an article 104 containing an aerosol-forming material to generate an aerosol or other inhalable material that can be inhaled by a user of the device 102. The device 102 includes an aerosol generator for heating the article 104 containing the aerosol-forming material. It will be appreciated that the device 102 may include other components not shown in FIG.

[0044] The device 102 comprises a body 103 defining a longitudinal axis 108 along which the articles 104 and filter element 106 extend when received within the device 102. The device 102 is configured such that airflow through the device 102 enters one end 110 of the body 103 and exits the other end 112 of the body 103, traveling generally along the longitudinal axis 108. The device 102 is elongated and has two ends 110, 112.

[0045] The first end 110 is capable of receiving the article 104 and the second end 112 is capable of receiving the filter element 106. A receptacle 114 for receiving the article 104 is defined at the first end 110. The receptacle 114 serves as an article receptacle. The receptacle 114 defines a heating area. A cavity 116 for receiving the filter element 106 is located at the second end 112. The cavity 116 serves as a filter cavity. Both ends 110, 112 of the device are flat and the device 102 presents a generally tubular profile that is generally oval in cross section. However, an elongated shape may alternatively be provided and the ends 110, 112 may not be flat.

[0046] The body 103 comprises an end surface of the device 102. A second end 112 of the device 102 closest to the cavity 116 may be considered the proximal end 112 (or mouth end) of the device 102 because it is closest to the user's mouth during use. During use, the user inserts the filter element 106 into the cavity 116 and operates the aerosol generator to initiate heating of the aerosol-generating material within the article receptacle 114 and inhale the aerosol generated within the device 102. This causes the aerosol to flow through the device 102 along a flow path towards the proximal end 112 of the device 102.

[0047] The other, first end 110 of the device 102, furthest from the cavity 116, may be understood as the distal end 110 of the device 102, as it is the end furthest from a user's mouth during use. When a user inhales the aerosol generated within the device 102, the aerosol flows in a direction towards the proximal end 112 of the device 102. The terms proximal and distal as applied to features of the device 102 are described by reference to the relative positioning of such features with respect to one another in the proximal-distal direction along the longitudinal axis 108.

[0048] 2 is a longitudinal cross-sectional view of the device 102 illustrated in FIG. 1. The cross-section of the receptacle 114 is generally cylindrical. The receptacle 114 extends into the device 102 at the distal end 112. The central axis of the receptacle 114 extends along the longitudinal axis 108 of the device 102. In other embodiments, the receptacle may not be cylindrical, but may exhibit, for example, an oval or rectangular cross-section. The receptacle 114 is shaped to complement or match the shape of the replaceable article such that the article 104 fits into the receptacle 114. The receptacle 114 is open at the first end 110 of the device to allow the replaceable article 104 to be placed therein.

[0049] The cavity 116 is also generally cylindrical in shape. The central axis of the cavity 116 coincides with the longitudinal axis 108 of the device 102 and is open at the second or proximal end 112 to allow the filter element 106 (not shown) to be disposed therein. The cavity 116 is shaped to complement or match the shape of the filter element 106 such that the filter element 106 fits into the cavity 116. The diameter of the cavity 116 is small compared to the diameter of the receptacle 114. However, the diameters of the cavity 116 and the receptacle 114 may be the same, or the diameter of the cavity 116 may be larger than the diameter of the receptacle 114.

[0050] The device 102 includes a flow passage 118 extending between the receptacle 114 and the cavity 116. The flow passage 118 provides a path for air flow through the device 102. The device 102 includes a converging portion 122 between the receptacle 114 and the flow passage 118. The converging portion 122 gradually decreases in cross-sectional area from the receptacle 114 to the flow passage 118. This may help avoid increased turbulence. In other embodiments, there is no converging portion.

[0051] The flow passage 118 extends directly from the receptacle 114 to the cavity 116. However, in other embodiments, the flow passage 118 may not extend directly from the receptacle 114 to the cavity 116, and there may be other components or passages therebetween. The flow passage 118 is in fluid communication with both the receptacle 114 and the cavity 116 to allow air to flow from the receptacle 114 to the cavity 116.

[0052] The flow passage 118 is elongated in shape. The flow passage 118 functions to space the cavity 116 from the receptacle 114. The flow passage 118 increases the distance and flow passage length between the cavity 116 and the receptacle 114 (as will be described in more detail in connection with FIG. 4).

[0053] The illustrated flow passage 118 is cylindrical in shape. However, other elongated shapes may be provided, for example elongated shapes exhibiting elliptical or square cross sections. While the illustrated flow passage 118 has a central axis that is straight, in other embodiments, the central axis is not straight and the flow passage 118 follows a non-linear path. The flow passage 118 may have a length to diameter ratio of at least 5, and in embodiments, a ratio of at least 10. The cross-sectional area of ​​the flow passage 118 is smaller than the cross-sectional areas of both the receptacle 114 and the cavity 116. This may help the flow passage 118 provide resistance (by friction) to the air flow therethrough. In other embodiments, the cross-sectional area of ​​the flow passage 118 may be the same as or larger than the cross-sectional areas of both the receptacle 114 and the cavity 116. Although one flow passage 118 is shown in this embodiment, multiple flow passages 118 are provided in other embodiments.

[0054] The flow passage 118 increases the length of the air flow path through the device 102. This means that the first end 110 can be spaced further away from the second end 112. It also means that the air must travel further from the receptacle 114 to the cavity 116. This configuration has various advantages, as will be explained in more detail below.

[0055] The flow passage 118 is defined by a tubular member 120 within the device. As air flows through the passage 118, the inner surface of the tubular member 120 exerts a frictional force on the airflow in a direction opposite to the direction of the airflow. This frictional force can be felt by a user upon inhalation, as described in more detail in connection with FIG. 4. In other embodiments, the device 102 does not include a tubular member 120, and instead the passage 118 is defined by a hole formed in the body 103.

[0056] The device 102 has a shoulder 124 between the passage 118 and the cavity 116. The shoulder 124 acts as a stop for the filter element 106 (not shown in FIG. 2 ) when inserted into the cavity 116, limiting the insertion of the filter element 106 into the cavity 116. In other embodiments, the stop for the filter element 106 is provided in the form of a flange or other protrusion. The stop is configured such that the filter element 106 protrudes from the cavity 116. The protruding portion can be used as a mouthpiece. In an embodiment, the device 102 comprises a mouthpiece. In such an embodiment, the cavity 116 may be configured to fully receive the filter element 106.

[0057] The device 102 may include user-operable controls (not shown), such as buttons or switches, that when operated, e.g., pressed, activate the device 102. For example, a user may activate the device 102 by pressing a switch.

[0058] The device 102 includes an aerosol generator for heating an exchangeable article 104 that includes an aerosol-generating material. The aerosol generator includes a heating assembly 126. The device further includes a controller 128 and a power source 130. The heating assembly 126 is configured to heat an aerosol-generating material inserted into the device 102 such that an aerosol is generated from the aerosol-generating material. The power source 130 provides electrical power to the heating assembly 126, which converts the provided electrical energy into thermal energy for heating the aerosol-generating material.

[0059] The illustrated power source 130 is a battery, which may be rechargeable or non-rechargeable. Examples of suitable batteries include, for example, lithium batteries (such as lithium ion batteries), nickel batteries (such as nickel cadmium batteries), and alkaline batteries.

[0060] Power supply 130 may be electrically coupled to heating assembly 126 to provide power to heat the aerosol-generating material when needed and under the control of controller 128. Control circuitry may be configured to activate and deactivate heating assembly 126 based on manipulation of control elements by a user. For example, controller 128 may activate heating assembly 126 in response to manipulation of a switch (not shown) by a user.

[0061] The heating assembly 126 may comprise various components for heating the aerosol-generating material of the article 104 via an induction heating process. Induction heating is a process of heating an electrically conductive heating element (such as a susceptor) by electromagnetic induction. The induction heating assembly may comprise an induction element, for example one or more inductor coils, and a device for passing a variable current, such as an alternating current, through the induction element. The variable current in the induction element generates a varying magnetic field. The varying magnetic field penetrates a heating element suitably positioned relative to the induction element, generating eddy currents within the heating element. The heating element is also known as a susceptor. The heating element has an electrical resistance to eddy currents, and thus the flow of eddy currents against this resistance causes the susceptor to heat by Joule heating. If the heating element comprises a ferromagnetic material, such as iron, nickel, or cobalt, heat may also be generated by magnetic hysteresis losses in the susceptor, i.e., by the varying orientation of magnetic dipoles in the magnetic material resulting from alignment with the varying magnetic field. Induction heating generates heat inside the heating element, allowing for faster heating than, for example, heating by conduction, and does not require any physical contact between the induction element and the heating element, allowing for greater freedom of construction and application.

[0062] The device 102 includes a heating element 132. The heating element 132 is in the form of an elongated member that protrudes into the receptacle 114. The elongated member may be configured as, for example, a pin or blade. The heating element 132 extends into the article 104 when the article 104 is inserted into the device 102. The heating element 132 functions as an internal heating element. The heating element 132 functions to heat the article 104. In other embodiments, the heating element 132 may be an external heating element. The heating element in an embodiment surrounds the article 104, or the device 102 may include both internal and external heating elements. The external heating element surrounds the heating area. In an embodiment, the heating element defines the heating area. The heating element forms at least a portion of the receptacle 114.

[0063] In other embodiments, the features functioning as heating elements 132 may not be limited to being inductively heated. The features functioning as heating elements may be, for example, heatable by electrical resistance. The aerosol generator 200 may include electrical contacts for electrical connection with an instrument for electrically activating the heating element by passing a flow of electrical energy through the heating element.

[0064] The receptacle 114 functions as a heating chamber and is configured and dimensioned to receive the item 104 to be heated. FIG. 3 is a plan view of the first side 110 of the device 102 without the item 104 inserted in the receptacle 114. The receptacle 114 is open at the first end 110 of the device and is closed at the inner end of the receptacle 114 by a bottom wall 134. The wall 134 acts as a stopper when the item 104 is inserted. The wall 134 has four holes 136 formed therein to allow air flow from the receptacle 114 to the passageway 118. The number of holes may vary or may be a single hole. The wall may have various configurations and may be a fluid permeable member. The holes 136 may provide additional resistance to air flow through the device 102. In other embodiments, the device 102 does not have the wall 134, and instead the receptacle 114 is open at its inner end. The shoulder in the embodiment is provided between the receptacle 114 and the flow passage 118. Also shown is a heating element 132 extending or protruding into the receptacle 114 from a wall 134. The wall 134 serves as a receptacle base. The device 102 may also have a connector 138 for connecting to a power source and / or for data transfer.

[0065] FIG. 4 illustrates the system 100 in use. As shown, the article 104 is disposed within the receptacle 114. The filter element 106 is disposed within the cavity 116. The filter element 106 protrudes from the second end 112 of the device 102. This protruding portion can be used as a mouthpiece for a user. In use, the user heats the article 104 by turning on the device 102. Once the article 104 is sufficiently heated so that the device 102 begins to generate aerosol-generating material, the user can inhale the aerosol-generating material using the filter element 106 as a mouthpiece. This inhalation causes air to flow from the first end 110 into the receptacle 114, as illustrated by the arrows. There, the air combines with the aerosol generated within the article 104. The aerosol then passes through the device 102 and through the filter element 116 toward the user. The air flow path is defined by holes 136 in wall 134, converging portion 122, passageway 118, and filter element 106. As the aerosol travels along this path, it may be inhaled by a user, allowing the user to ingest the aerosol produced by article 104.

[0066] The filter element 106 acts as a filter to prevent the user from inhaling certain sizes and / or types of particles. The amount and type of filtration can be selected depending on the device at hand and the user's preferences.

[0067] FIG. 5 illustrates a consumable 105 comprising an aerosol generating element or article 104 and a filter element 106. The aerosol generating element 104 may be suitable for disposing in a receptacle 114 in the device 102 described above. The filter element 106 may be suitable for disposing in a cavity 116 in the device 102 described above. The consumable 105 has a joint 107 between the aerosol generating element 104 and the filter element 106. The joint 107 has a line of weakness such that the aerosol generating element 104 and the filter element 106 are separable along the joint 107. The line of weakness allows a user to manually separate the aerosol generating element from the filter element 106, for example, by pulling the aerosol generating element 104 apart. The aerosol generating element 104 and the filter element 106 illustrated in FIG. 5 have the same diameter. However, in other embodiments, the aerosol generating element 104 and the filter element 106 may have different diameters.

[0068] The passageway 118 functions to space the receptacle 114 from the cavity 116. This may help to reduce the temperature of the air ingested by the user, as the air cools as it travels through the passageway 118. This may reduce the "hot puff" phenomenon and avoid harm to the user from high temperatures.

[0069] The presence of the passageway 118 allows for a more elongated shape of the device 102. By more elongated, it is meant that the ratio of the length of the device to the width or height of the device can be higher than a device that does not have the passageway 118. For example, an elongated device 102 may have a length to width or height ratio of at least 3, or at least 6. Providing a more elongated device 102 may help improve the ergonomics of the device, as it may be easier to hold. An elongated device may also be more familiar to a user, for example, as it may more closely resemble the shape of a cigarette.

[0070] The passageway 118 serves to provide additional resistance to the airflow through the device 102. This is because as the airflow moves through the passageway 118, it experiences frictional forces from the walls of the passageway 118. This resistance to flow may be experienced by the user when inhaling. This may serve to improve the user experience, which may be more similar to a cigarette, for example, and therefore more familiar to the user.

[0071] The device 102 having the passageway 118 also allows the article 104 containing the aerosol-generating material to be separated from the filter element 106. This means that the filter element 106 can be replaced at a different frequency than the article 104. This is advantageous because the filter element 106 does not need to be replaced as frequently as the article 104. Thus, because the article 104 and the filter element 106 are separate, the article 104 can be replaced without replacing the filter element 106. This can help reduce costs and waste because the filter element 106 is not replaced prematurely and unnecessarily, as is the case with consumables that have an integrated article and filter.

[0072] In any of the described embodiments, the apparatus 102 may be configured to heat the article by generating a varying magnetic field configured to heat a susceptor heating element disposed within the article. That is, the article itself may comprise a heating element. When positioned in the heating zone, the heating element disposed within the article generates heat in the presence of the varying magnetic field, thereby heating the article and generating aerosolized material from the aerosol-generating material.
