[0012] As used herein, the term “aerosol-generating material” refers to a material that can generate an aerosol when, for example, heated, irradiated, or otherwise energized. Aerosol-generating materials may be in the form of a solid, liquid, or gel, which may or may not contain active substances and / or flavorings. Aerosol-generating materials may also include any plant-based material, such as tobacco-containing material, and may include one or more of the following: tobacco, tobacco derivatives, expanded tobacco, recombined tobacco, or tobacco substitutes. Aerosol-generating materials may also include other non-tobacco products, which may or may not contain nicotine, depending on the product. Aerosol-generating materials may be in the form of, for example, a solid, liquid, gel, or wax. Aerosol-generating materials may also be, for example, a combination or blend of materials. Aerosol-generating materials may also be known as “smoked material.”

[0013] The aerosol-generating material may include a binder and an aerosol-forming agent. Optionally, an active substance and / or filler may be present. Optionally, a solvent such as water may also be 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-based materials. In some embodiments, the aerosol-generating material is substantially free of tobacco.

[0014] The aerosol-generating material may include or may be an amorphous solid. The amorphous solid may be a monolithic solid. In some embodiments, the amorphous solid may be a dry gel. The amorphous solid is a solid material capable of holding some fluid, such as a liquid, within the amorphous solid. In some embodiments, the aerosol-generating material may include, for example, about 50% by weight, 60% by weight, or 70% by weight of amorphous solid, or about 90% by weight, 95% by weight, or 100% by weight of amorphous solid.

[0015] The aerosol-generating material may include an aerosol-generating film. The aerosol-generating film may include, or may be, a sheet that can be optionally shredded to form shredded sheets. The sheet may be a crimped sheet. The aerosol-generating sheet or shredded sheet may not substantially contain tobacco.

[0016] According to this disclosure, a “non-combustible” aerosol supply system is a system in which the aerosol-generating materials (or their components) that make up the aerosol supply system are not burned or incinerated in order to facilitate the delivery of at least one substance to the user.

[0017] In some embodiments, the delivery system is a non-combustible aerosol supply system, such as a powered non-combustible aerosol supply system.

[0018] 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), but it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0019] In some embodiments, the non-combustion aerosol supply system is an aerosol-generating material heating system, also known as a non-combustion heating system. An example of such a system is a cigarette heating system.

[0020] In some embodiments, the non-combustible aerosol supply system is a hybrid system that generates an aerosol using a combination of one or more aerosol-generating materials that can be heated. Each of the aerosol-generating materials may be, for example, in the form of a solid, liquid, or gel, 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.

[0021] Typically, a non-combustion aerosol supply system may comprise a non-combustion aerosol supply device and an article for use with the non-combustion aerosol supply device, generally a consumable.

[0022] In some embodiments, the present disclosure relates to consumables that comprise an aerosol-generating material and are configured to be used with a non-combustion aerosol supply device. These consumables may sometimes be referred to as articles throughout the present disclosure.

[0023] In some embodiments, a non-combustion aerosol supply system, such as its non-combustion aerosol supply device, may comprise a power source and a controller. The power source may be, for example, a power source or a heat-generating power source. In some embodiments, the heat-generating power source comprises a carbon-based substrate that can be energized to distribute power in the form of heat to an aerosol-generating material or a heat transfer material in proximity to the heat-generating power source.

[0024] In some embodiments, the non-combustion aerosol supply system may comprise an area for receiving a consumable, an aerosol generator, an aerosol generation area, a housing, a suction port, a filter, and / or an aerosol modifier.

[0025] In some embodiments, consumables for use with a non-combustion aerosol supply device may comprise an aerosol-generating material, an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generator, an aerosol generation area, a housing, a packaging material, a filter, a suction port, and / or an aerosol modifier.

[0026] An aerosol generating device can accept an article containing an aerosol generating material for heating. In this context, “article” means the aerosol generating material that is heated during use to volatilize, and optionally other components that are included or contain other components during use. The user may insert the article into the aerosol generating device before the article is heated to generate an aerosol, after which the user inhales the aerosol. The article may be of a predetermined or specific size, for example, configured to be placed in a heating chamber of a device sized to accept the article.

[0027] Referring to Figure 1, the aerosol supply system 10 comprises an aerosol supply device 100 for generating an aerosol from an aerosol-generating material. The aerosol supply system 10 further comprises a replaceable article 110 containing the aerosol-generating material. Schematically, the aerosol-forming device 100 may be used to heat the article 110 to generate an aerosol or other inhalable medium to be inhaled by a user of the device 100.

[0028] The aerosol forming device 100 comprises a main body 102. The housing 202 surrounds and accommodates various components of the main body 102. An article opening 104 is formed at one end of the main body 102, into which an article 110 can be inserted for heating by the aerosol generator 200.

[0029] Device 100 may also include a user-operable control element 150, such as a button or switch, which operates Device 100 when pressed. For example, a user may turn on Device 100 by operating the switch 150.

[0030] The aerosol generator 200 defines a longitudinal axis that aligns with the axis of the article 110.

[0031] During use, article 110 may be fully or partially inserted into the aerosol generator 200 and may be heated by one or more components of the aerosol generator 200.

[0032] Device 100 includes an apparatus for heating an aerosol-generating material. The apparatus includes an aerosol-generating assembly, a controller (control circuit), and a power source. The apparatus forms part of the main body 102. The aerosol-generating assembly is configured to heat the aerosol-generating material of an article 110 inserted through an article opening 104 so that an aerosol is generated from the aerosol-generating material. The power source supplies power to the aerosol-generating assembly, which converts the supplied electrical energy into thermal energy for heating the aerosol-generating material. The power source may be a battery, such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries.

[0033] The power source is electrically connected to the aerosol generation assembly and can supply power to heat the aerosol generation material under the control of the controller when needed. The control circuit may be configured to start and stop the aerosol generation assembly based on user input. User input may be a button press or the opening of a device door (e.g., a door covering a consumable receiving receptacle). The control circuit may be configured to start and stop automatically, for example, when an item is inserted.

[0034] An aerosol generation assembly may comprise various components for heating an aerosol-generating material through an induction heating process. Induction heating is a process of heating a conductive heating element (such as a susceptor) by electromagnetic induction. An 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 fluctuating magnetic field. The fluctuating magnetic field penetrates a susceptor (heating element) appropriately positioned relative to the induction element, generating eddy currents inside the susceptor. The susceptor has electrical resistance to eddy currents, and therefore, the flow of eddy currents against this resistance heats the susceptor by Joule heating. If the susceptor contains a ferromagnetic material such as iron, nickel, or cobalt, heat can also be generated by magnetic hysteresis losses within the susceptor, i.e., by a change in the orientation of magnetic dipoles in the magnetic material as a result of alignment with the fluctuating magnetic field. Compared to heating by conduction, for example, induction heating generates heat inside the susceptor and allows for rapid heating. Furthermore, since no physical contact is required between the inductive element and the susceptor, it becomes possible to increase the degree of freedom in construction and application.

[0035] Referring to Figure 2, the aerosol supply device 10 comprises a housing 202 and a cover 204. The aerosol supply device 10 has a mouthpiece end 205 from which a user can inhale aerosol. The aerosol supply device 10 also has a distal end 207 opposite the mouthpiece end 205. The aerosol supply device 10 has an elongated shape that defines its longitudinal direction.

[0036] The housing 202 comprises a cavity. The cavity may be a compartment for housing an energy storage compartment, such as a battery (not shown). The aerosol supply device 10 may be electrically coupled to the cavity so that the energy storage device housed within the cavity can be used to supply electrical energy to operate the aerosol supply device 10. The housing 202 comprises an opening 203 that provides access to the cavity for inserting and / or removing, for example, a battery. In this embodiment, the opening 203 is located at the distal end 207 of the aerosol supply device 10. The housing 202 further comprises a housing connector 206 configured to engage with the cover 204 to hold the cover 204 in place. The housing connector 206 is located within the opening 203. The housing connector 206 extends inward from the housing 202 toward the center of the opening 203.

[0037] The cover 204 is configured to close the opening 203. The cover 204 includes a cover connector 208 that can engage with a housing connector 206 so that the cover 204 can be removably attached to the housing 202. The cover 204 is movable relative to the housing 202 between a connected position and a disconnected position. In the connected position, the cover connector 208 engages with the housing connector 206 to resist relative movement between the housing 202 and the cover 204. In the connected position, the cover 204 closes at least a portion of the opening 203. In the disconnected position, the cover connector 208 is separated from the housing connector 206 (i.e., not engaged with the housing connector 206) so that the cover 204 can move relative to the housing 202. In the disconnected position, the cover 204 can be removed from the opening 203, thereby allowing access to a cavity through the opening 203. Usefully, this configuration provides a simple and / or efficient way to selectively access and cover a cavity, such as a battery compartment. Therefore, the time and effort required for battery replacement, repair, or recycling are reduced by the configuration described above.

[0038] In this embodiment, the housing connector overlaps the opening and covers a portion of it. In other embodiments, the housing connector does not overlap the opening. In some embodiments, the cover completely closes the opening. In other embodiments, the cover does not close the entire opening; for example, the cover may be configured to close a limited portion of the opening. In this embodiment, the movement of the cover from a connected position to a disconnected position involves rotation of the cover relative to the housing about the longitudinal direction. In other embodiments, the movement of the cover from a connected position to a disconnected position does not involve rotation of the cover relative to the housing about the longitudinal direction; for example, the movement may include linear movement.

[0039] Referring to Figures 3A and 3B, the housing connector 206 comprises two housing collars 302. Each of the housing collars 302 can be considered a projection, lip, or flange. The housing collars 302 extend radially inward from the inner wall of the cavity of the housing 202.

[0040] The cover connector 208 comprises two cover rims 304. The cover rims 304 extend radially outward from the cover 204. Each of the cover rims 304 defines its respective channel. Each of the channels can be thought of as a slot, groove, or flange. Each of the channels is sized to receive its respective housing collar 302. Each of the housing collars 302 has a shape complementary to its respective channel. Each of the housing collars 302 may be received within its respective channel. In the connection position (shown in Figure 3B), each of the housing collars 302 is positioned within its respective channel, thereby preventing the cover 204 from moving longitudinally relative to the housing 202. In the connection position, the cover rims 304 are inside the cavities.

[0041] At the connection position, each of the housing collars 302 abuts against and / or engages with the cover rim 304 in the longitudinal direction to prevent movement that could cause the cover 204 to separate from the housing 202.

[0042] The housing connector 206 and cover connector 208 extend circumferentially with respect to the opening 203. As will be described in more detail below, the total circumferential extent of the housing connector 206 and cover connector 208 is smaller than the circumference of the opening 203.

[0043] The internal radial separation distance between the two housing collars 302 is smaller than the distance between the radial outer edges of the two cover rims 304. Thus, once each housing collar 302 is received within its respective channel, the cover rim 304 cannot move beyond the housing collar 302 through the opening 203, and the cover 304 is held in place by the housing 202. The housing collars 302 and the cover rims 304 overlap at the connection point.

[0044] The diameter of the opening 203 is substantially the same as or greater than the distance between the radial outer edges of the two cover rims 304. The internal radial separation distance between the two housing collars 302 is substantially the same as or greater than the outer distance between the opposing portions of the cover 202 where the two cover rims 304 are absent.

[0045] To removably attach the cover 202 to the housing 204, the cover 202 is initially positioned so that the cover rim 304 aligns with the portion of the housing that does not have a housing collar 304, and / or the housing collar 304 aligns with the portion of the cover 204 that does not have a cover rim 304. In this configuration, the cover 204 can move longitudinally into and / or through the opening 203. This is possible because the circumferential range of the housing connector and cover connector is smaller than the circumference of the opening. The circumferential spacing between the housing collars 302 is greater than the circumferential range of each cover rim 304.

[0046] Next, the cover 204 is rotated around its longitudinal axis such that the cover rim 304 engages with and / or abuts against the housing collar 302 and the housing collar 302 is received within its respective channel. In this position, the cover 204 is held in place relative to the housing 202. Usefully, this configuration ensures that the opposing edges of the cover 204 are securely fixed to the housing 202, thereby improving the retention of the cover 204 relative to the housing 202.

[0047] To remove the cover 202 from the housing 204, the cover 202 is rotated in the opposite direction so that the cover rim 304 aligns with the portion of the housing 202 that does not have the housing flange 304, and / or the housing flange 304 aligns with the portion of the cover 204 that does not have the cover rim 304. In this configuration, the cover 204 can move through and / or through the opening 203.

[0048] In this embodiment, the cover is substantially circular in shape. In other embodiments, the cover may not be circular, for example, it may have a square or rhombus shape. In this embodiment, the cover connector has two channels, each configured to receive its respective flange. In other embodiments, the cover connector does not have two channels, for example, it may have only one channel, or it may have a flange instead. In some embodiments, the channels may be located on adjacent sides of the cover. In this embodiment, the housing connector has two flanges. In other embodiments, the housing connector does not have two flanges, for example, it may have only one flange, or it may have a channel instead. In some embodiments, the flanges may be located on adjacent sides of the housing.

[0049] Referring to Figures 4 and 5, the cover 204 includes a cover limiter 402. The housing 202 includes a housing limiter 502. The cover limiter 402 is configured to contact the housing limiter 502 on the housing 202 to restrict the movement of the cover 204 beyond the connection position. In other words, the cover limiter 402 engages with the housing limiter 502 at the connection position to prevent the cover 204 from rotating further relative to the housing 202 (in either direction). In the embodiment shown in Figure 4, the cover limiter 402 includes two posts. Each post extends along a direction perpendicular to the plane defined by the cover 402, i.e., longitudinally. Each post is configured to engage with the corresponding housing limiter 502 to hold the cover in place when it is in the connection position.

[0050] In this embodiment, the cover limiter comprises two posts. In other embodiments, the cover limiter does not comprise two posts; for example, the cover limiter may comprise only one post, or it may comprise a flexible arm. In some embodiments, the cover limiter may comprise a projection.

[0051] Referring to Figure 5, in some embodiments, the housing 202 includes a housing limiter 502. The housing limiter 502 is configured to engage with the cover limiter 402 to restrict the movement of the cover 204 beyond its connection position. In the embodiment shown in Figure 5, the housing limiter 502 includes two deformable arms 503. Each of the arms 503 is configured to engage with the respective posts of the cover limiter 402. Each of the arms 503 is sized such that, as the posts rotate, each of its posts exerts a force on the arm 502, thereby deforming the arm 502. The force applied to the arm 503 may be circumferential and / or radial. Each of the arms 503 includes a recess 504 where its respective post is located at the connection position. The recess 504 is formed by an arm 503 including a radially extending bump that contacts the post. The recess 504 can be considered a stopper and / or fastener for the cover limiter 402. When moving from the unconnected position to the connected position, the post on the cover 204 moves over the bump on the housing limiter 502. While in the connected position, the cover 204 is locked in place relative to the housing 202.

[0052] In this embodiment, the housing limiter 502 comprises two deformable arms 503. In other embodiments, the housing limiter 502 does not comprise two deformable arms; for example, the housing limiter 502 may comprise only one arm, or the housing limiter 502 may instead comprise one or more posts.

[0053] In other embodiments, the cover limiter and housing limiter are reversed, with the post included in the housing limiter and the arm included in the cover limiter.

[0054] In other embodiments, the cover connector and housing connector are reversed, with the cover connector having a lip extending radially inward and the housing connector having a lip extending radially outward. In such embodiments, the cover can be mated to the distal end of the housing.

[0055] Usefully, the above arrangement of the housing and cover limiter helps prevent the cover from moving unintentionally from its connection position. This provides a cover that is movable relative to the housing between the connection and disconnection positions. Furthermore, the cover connector engages with the housing connector when the cover moves to the connection position, and the cover connector and housing connector connect the cover to the housing when the cover is in the connection position. In addition, the cover limiter is provided to contact the housing limiter to restrict the cover from moving beyond the connection position. Thus, a removable cover can be achieved without resulting in structural weaknesses or reduced usability.

[0056] Referring to Figure 6, a tool 602 may be provided for rotating the cover 204 to attach the cover 204 to the housing 202, or for removing the cover 204 from the housing 202. The cover 204 is provided with an engagement opening 604. The engagement opening 604 may be a tool engagement component. The engagement opening 604 has a shape consisting of a central circle and two opposing wings positioned at the edge of this circle.

[0057] The tool 602 comprises a head portion and a handle portion. The head portion includes an engaging projection 606 having a shape complementary to the shape of the engaging opening 604. The engaging projection 606 is fittable into the engaging opening 604. The handle portion extends from the head portion. The handle portion has length in its extension direction so that the handle portion can be held or grasped by a human hand. When the engaging projection 606 is positioned inside the engaging opening 604, the cover 204 rotates by rotating the tool 602 around the head portion, for example by rotating the handle portion around the head portion. The rotation of the cover 204 may cause the cover 204 to be attached to / detached from the housing 202.

[0058] Usefully, the tool 602 makes it easier to attach and detach the cover 204. Usefully, the tool 602 makes the cover 204 lighter and / or more compact, thereby making the aerosol supply device 10 smaller and / or lighter. For example, since the rotation of the cover 204 is provided by the engagement opening, there is no need to add parts to the cover 204 to facilitate its rotation. Furthermore, the engagement opening 604 removes material from the cover 204, thereby making the cover 204 lighter. Usefully, the wing-shaped engagement opening 604 and / or engagement projection 606 can further facilitate the rotation of the cover 204.

[0059] In this embodiment, a tool is provided. In other embodiments, no tool is provided. In this embodiment, the shape of the engagement opening and / or engagement projection is a central circle having two opposing wings positioned at the edge of the circle. In other embodiments, the shape of the engagement opening and / or engagement projection is not a central circle having two opposing wings positioned at the edge of the circle, but for example, the shape of the engagement opening and / or engagement projection may be a line, or two separate circles, or an ellipse, or an irregular shape. In this embodiment, the shapes of the engagement opening and the engagement projection are the same. In other embodiments, the shapes of the engagement opening and the engagement projection are not the same, for example, the engagement opening is larger than the engagement projection. In some embodiments, a limited portion of the engagement projection is complementary to a limited portion of the engagement opening. In this embodiment, the cover has an engagement opening and the tool has an engagement projection. In other embodiments, the cover does not have an engagement opening and the tool does not have an engagement projection; for example, the cover has an engagement projection and the tool has an engagement opening.
