Description

Technical Field

[0001] The present disclosure relates to an aerosol generating device including a first housing part and a second housing part movable relative to the first housing part. The present disclosure also relates to an aerosol generating article including a first mouthpiece element at a first end of the aerosol generating article and a second mouthpiece element at a second end of the aerosol generating article. The present disclosure also relates to an aerosol generating article including a wrapper and a plurality of spaced-apart marks on an outer surface of the wrapper.

Background Art

[0002] Numerous electrically-operated aerosol generating systems have been proposed in the art that use an electrical heater to heat an aerosol-forming substrate such as a tobacco plug. The aerosol generating substrate may be provided as part of an aerosol generating article inserted into a cavity of the aerosol generating device.

[0003] Typically, an aerosol generating device comprises a housing defining a cavity for receiving the aerosol generating article. The housing may have a shape intended to provide ergonomic benefits to the user, but typically the size and shape of the housing are determined by the need to accommodate the cavity, the electrical heater, the power source, and the control electronics. Thus, known aerosol generating devices often have a size and shape that can provide only limited ergonomic benefits to the user.

Summary of the Invention

Problems to be Solved by the Invention

[0004] It is desirable to provide an aerosol generating device that can provide improved ergonomic benefits to the user.

[0005] Aerosol generating articles typically include an aerosol-forming substrate, such as a cigarette plug, and a mouthpiece downstream of the cigarette plug. The mouthpiece typically includes a filter element. Such aerosol generating articles may offer user-specific options to customize the user experience. Therefore, some users may attempt to use the aerosol generating article in a manner not intended by the manufacturer. For example, a user may attempt to heat only a portion of the aerosol-forming substrate by using the aerosol generating article without fully inserting it into the aerosol generator. However, as a result, the portion of the aerosol-forming substrate will not be heated and will therefore be wasted. Furthermore, using the aerosol generating article in this manner may reduce the consistency from one user experience to the next. Other users may remove a portion of the aerosol-forming substrate by cutting the aerosol generating article before inserting it into the aerosol generator. This results in a further problem of reduced pull resistance, which can also negatively impact the user experience.

[0006] It is desirable to provide aerosol generating articles that can easily customize the user experience. [Means for solving the problem]

[0007] According to one aspect of the present disclosure, an aerosol generator is provided. The aerosol generator may comprise a first housing portion. The first housing portion may define a cavity for receiving an aerosol generating article. The aerosol generator may comprise a second housing portion. The second housing portion may extend from the first housing portion. The second housing portion may be movable relative to the first housing portion. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] According to another aspect of the present disclosure, an aerosol generator is provided, comprising a first housing portion defining a cavity for receiving an aerosol-generating article, and a second housing portion extending from the first housing portion. The second housing portion is movable relative to the first housing portion.

[0010] Advantageously, providing a second housing portion that is movable relative to the first housing portion makes it possible to provide an aerosol generator having at least one of variable size and shape. Advantageously, moving the second housing portion relative to the first housing portion allows the user to position the second housing portion in a way that improves or optimizes user comfort when holding the aerosol generator. Users may have different preferred positions of the second housing portion relative to the first housing portion. Advantageously, a movable second housing portion can accommodate different user preferences.

[0011] The second housing portion may be rotatable around the first housing portion. Advantageously, a rotatable second housing portion can facilitate movement of the second housing portion over a range of typically preferred positions of the second housing relative to the first housing portion.

[0012] The aerosol generator may include at least one shaft portion, and a second housing portion is movable and connected to a first housing portion by at least one shaft portion.

[0013] At least one shaft portion can be integrally formed with the first housing portion. At least one shaft portion can be formed separately from the first housing portion and may be fixed to the first housing portion. The second housing portion may include at least one bearing portion, and at least one shaft portion may be rotatably received within at least one bearing portion. At least one bearing portion may include at least one opening within the second housing portion, and at least one shaft portion may be rotatably received within at least one opening.

[0014] At least one shaft portion can be integrally formed with the second housing portion. At least one shaft portion can be formed separately from the second housing portion and may be fixed to the second housing portion. The first housing portion may include at least one bearing portion, and at least one shaft portion may be rotatably received within at least one bearing portion. At least one bearing portion may include at least one opening within the first housing portion, and at least one shaft portion may be rotatably received within at least one opening.

[0015] The second housing portion may be movably connected to the first housing portion by a ball and socket joint. At least a portion of the first housing portion may include a first curved surface. The first curved surface may form the ball portion of the ball and socket joint. At least a portion of the second housing portion may include a second curved surface. The second curved surface may form the socket portion of the ball and socket joint.

[0016] Preferably, the cavity includes a first cavity end and a second cavity end opposite the first cavity end, and the cavity defines a first direction extending between the first cavity end and the second cavity end.

[0017] The first housing portion may define a first opening at the first cavity end and a second opening at the second cavity end. In other words, the cavity may be a through-cavity, and the aerosol-generating article may be inserted into the cavity at the first cavity end or the second cavity end.

[0018] Advantageously, providing a through-cavity can facilitate removal of the aerosol-generating article from the cavity. For example, the user may push on an end of the aerosol-generating article such that the aerosol-generating article is pushed out of the cavity at the opposite end. Advantageously, removing the aerosol-generating article by pushing it through the cavity rather than pulling it out of the cavity can reduce or minimize the risk that a portion of the aerosol-forming substrate remains in the cavity.

[0019] Advantageously, providing a through-cavity can facilitate use of an aerosol-generating device having an aerosol-generating article with a length greater than the length of the cavity. For example, during use, the aerosol-generating article may protrude from the cavity at the first cavity end, the second cavity end, or both the first cavity end and the second cavity end.

[0020] Advantageously, providing a through-cavity can facilitate cleaning of the cavity. For example, a brush or other cleaning tool can be pushed through the cavity, thereby facilitating removal of debris and other contaminants from the cavity.

[0021] Advantageously, providing a through-cavity can facilitate a single airflow path through the aerosol-generating device during use. In particular, air may flow directly through the aerosol-generating article received in the cavity without requiring a dedicated airflow inlet or outlet for the aerosol-generating device.

[0022] Preferably, the cavity has a circular cross-sectional shape. Advantageously, the circular cross-sectional shape facilitates the use of aerosol generators having aerosol generating articles having a circular cross-sectional shape. Advantageously, the circular cross-sectional shape may allow the user to insert the aerosol generating article into the cavity in any rotational orientation.

[0023] In an embodiment in which the first housing portion defines the first opening and the second opening, it is preferable that the inner diameter of the first opening is the same as the inner diameter of the second opening.

[0024] The aerosol generator may include a first closing member positioned to selectively block at least a portion of the first opening.

[0025] The first closing member may be configured to engage the aerosol-generating article when the article is received into the cavity. Advantageously, the first closing member may hold the aerosol-generating article within the cavity.

[0026] The first closure member may be positioned to selectively close substantially all of the first opening. Advantageously, the first closure member can selectively provide a surface to which the aerosol-generating article is received when the aerosol-generating article is inserted into the cavity through the second opening. Advantageously, the first closure member can facilitate the correct positioning of the aerosol-generating article within the cavity.

[0027] The first closing member may be arranged to slide relative to the first housing portion. The first closing member may be arranged to rotate relative to the first housing portion.

[0028] The first closing member may be movable between an open position in which the first opening is not blocked and a closed position in which the first closing member blocks at least a portion of the first opening. In embodiments in which the first closing member is positioned to selectively block substantially all of the first opening, preferably the first closing member blocks substantially all of the first opening when the first closing member is in the closed position.

[0029] The aerosol generator may include a first biasing member arranged to bias the first closing member toward the closed position. The first biasing member may include a spring.

[0030] The aerosol generator may include a first retainer configured to engage with the first closure member to hold the first closure member in the closed position.

[0031] The aerosol generator may include a second closing member positioned to selectively block at least a portion of the second opening.

[0032] The second closing member may be configured to engage with the aerosol-generating article when the article is received into the cavity. Advantageously, the second closing member may hold the aerosol-generating article within the cavity.

[0033] The second closing member may be positioned to selectively close substantially all of the second opening. Advantageously, the second closing member can selectively provide a surface to which the aerosol-generating article is received when the aerosol-generating article is inserted into the cavity through the first opening. Advantageously, the second closing member can facilitate the correct positioning of the aerosol-generating article within the cavity.

[0034] The second closing member may be positioned to slide relative to the first housing portion. The second closing member may be positioned to rotate relative to the first housing portion.

[0035] The second closing member may be movable between an open position in which the second opening is not blocked and a closed position in which the second closing member blocks at least a portion of the second opening. In embodiments in which the second closing member is positioned to selectively block substantially all of the second opening, it is preferable that the second closing member blocks substantially all of the second opening when it is in the closed position.

[0036] The aerosol generator may include a second biasing member positioned to bias the second closing member toward the closed position. The second biasing member may include a spring.

[0037] The aerosol generator may include a second stopper configured to engage with the second closing member and hold the second closing member in the closed position.

[0038] Preferably, the second housing portion has an elongated shape and comprises a first housing end connected to the first housing portion for movement relative to the first housing portion, and a second housing end opposite to the first housing end.

[0039] The term “elongated” is used herein to refer to a shape having a length and a width perpendicular to the length, where the length-to-width ratio is at least 1.5 to 1.

[0040] Advantageously, the elongated second housing portion can facilitate the user's use of it as a handle. In other words, the user may hold the aerosol generator by the second housing portion while using the aerosol generator.

[0041] The second housing portion may define a second direction extending between the first housing end and the second housing end, and the second housing portion is movable relative to the first housing portion to a position where the second direction is perpendicular to the first direction. Advantageously, the position where the second direction defined by the second housing portion is perpendicular to the first direction defined by the cavity can facilitate the use of the second housing portion as a handle.

[0042] Preferably, the second housing portion is rotatable relative to the first housing portion through an angular range between the first and second directions. The angular range preferably includes an angle of 90 degrees between the first and second directions. The second housing portion may also be rotatable relative to the first housing portion from a first position to a second position.

[0043] The aerosol generator may include at least one mark on at least one of the first housing portion and the second housing portion, the at least one mark being positioned to indicate the position of the second housing portion relative to the first housing portion.

[0044] The aerosol generator may include a locking mechanism configured to selectively prevent the movement of the second housing portion relative to the first housing portion. Advantageously, the locking mechanism can prevent undesirable movement of the second housing portion relative to the first housing portion during use of the aerosol generator.

[0045] The locking mechanism may include a ratchet mechanism. Advantageously, the ratchet mechanism can facilitate the movement of the second housing portion to one or more predetermined positions relative to the first housing portion.

[0046] Preferably, the aerosol generator comprises an electric heater, a power supply, and a controller configured to supply power from the power supply to the electric heater. Advantageously, during use, the electric heater may heat the aerosol-forming substrate of the aerosol-generating article received in the cavity.

[0047] It is preferable to position the electric heater within the first housing portion.

[0048] Advantageously, positioning the electric heater within the first housing portion facilitates the heating of the aerosol-generating article received within the cavity defined by the first housing portion.

[0049] Advantageously, positioning the electric heater within the first housing portion can reduce or minimize heating of the second housing portion during use of the aerosol generator. Furthermore, reducing or minimizing heating of the second housing portion can improve user comfort when the user holds the aerosol generator by the second housing portion during use.

[0050] Preferably, when an aerosol-generating article is inserted into the cavity, the electric heater extends around at least a portion of the cavity so that at least a portion of the aerosol-generating article is received within the electric heater. In an arrangement where the aerosol-generating article is received within the electric heater, the electric heater may be referred to as an “external heater.” An external heater may be particularly advantageous in embodiments where the cavity is a through-cavity.

[0051] Preferably, at least one of the power supply and the controller is located within the second housing portion. Preferably, both the power supply and the controller are located within the second housing portion.

[0052] Advantageously, positioning the power supply and controller within the second housing portion can reduce or minimize heat transfer from the electric heater to the power supply and controller during use of the aerosol generator. Advantageously, reducing or minimizing heating of the power supply and controller can reduce, minimize, or prevent thermal damage to the power supply and controller.

[0053] Advantageously, positioning the power supply and controller within the second housing portion allows the center of mass of the aerosol generator to be located within the second housing portion. Advantageously, positioning the center of mass of the aerosol generator within the second housing portion can enhance user comfort when the user holds the aerosol generator within the second housing portion during use.

[0054] The electric heater may include an induction heating element. During use, the induction heating element inductively heats the susceptor material, thereby heating the aerosol-generating article received in the cavity. The susceptor material may form part of the aerosol generator. The susceptor material may also form part of the aerosol-generating article. The induction heating element may include at least one inductor coil extending around at least a portion of the cavity so that at least a portion of the aerosol-generating article is received within the inductor coil when the aerosol-generating article is inserted into the cavity.

[0055] The electric heater may include a resistance heating element. During use, an electric current is supplied to the resistance heating element to generate heat by resistance heating. The resistance heating element may include a foil heater. Preferably, the foil heater is wrapped around at least a portion of the cavity so that at least a portion of the aerosol generating article is received within the foil heater when the aerosol generating article is inserted into the cavity.

The power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery. Suitable lithium batteries may include lithium-cobalt batteries, lithium iron phosphate batteries, and lithium polymer batteries. The power source may also include other forms of charge storage devices, such as capacitors. The power source may require recharging. The power source may have a capacity that allows for sufficient energy storage to use the aerosol generator with one or more aerosol generating articles.

[0057] Each of the first and second housing portions may contain any suitable material or combination of materials. Examples of suitable materials include metals, alloys, plastics, or composite materials containing one or more of these materials, or thermoplastic resins suitable for food or pharmaceutical applications, such as polypropylene, polyetheretherketone (PEEK), and polyethylene. The material is preferably lightweight and not brittle.

[0058] Another aspect of the present disclosure provides an aerosol generating article comprising at least one aerosol-forming substrate, and an aerosol generating system comprising an aerosol generating device according to the present disclosure.

[0059] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming substrate that releases a volatile compound capable of forming an aerosol when heated.

[0060] The aerosol generating article may comprise at least one mouthpiece element. The at least one mouthpiece element may be adjacent to the aerosol forming substrate. The at least one mouthpiece element may be spaced apart from the aerosol forming substrate. The aerosol generating article may comprise at least one additional element positioned between the aerosol forming substrate and the at least one mouthpiece element. The at least one additional element may comprise an aerosol cooling element.

[0061] The aerosol-generating article may include a wrapper. Preferably, the wrapper is wrapped around the aerosol-forming substrate and, if present, consists of at least one mouthpiece element and at least one additional element.

[0062] According to another aspect of the present disclosure, an aerosol-generating article is provided. The aerosol-generating article may comprise a first mouthpiece element, which may be located at a first end of the aerosol-generating article. The aerosol-generating article may comprise a second mouthpiece element, which may be located at a second end of the aerosol-generating article. The aerosol-generating article may comprise at least one aerosol-forming substrate, which may be located between the first and second mouthpiece elements.

[0063] In another aspect of the present disclosure, an aerosol generating article is provided, comprising a first mouthpiece element positioned at a first end of the aerosol generating article and a second mouthpiece element positioned at a second end of the aerosol generating article. The aerosol generating article also comprises at least one aerosol-forming substrate positioned between the first and second mouthpiece elements.

[0064] Advantageously, providing first and second mouthpiece elements at the first and second ends of the aerosol generating article can facilitate the use of both ends of the aerosol generating article as “mouth-side ends” that are received in the user’s mouth during use.

[0065] Advantageously, by providing an aerosol generating article having two mouth-side ends, it may be possible for the user to insert the aerosol generating article into the aerosol generating device in different orientations.

[0066] Advantageously, an aerosol generating article having two mouth ends may be particularly suitable for an aerosol generating device that includes a through cavity for receiving the aerosol generating article. In such an arrangement, the aerosol generating article may be inserted into the through cavity with its first mouth end protruding from the first end of the through cavity and its second end protruding from the second end of the through cavity.

[0067] Advantageously, providing an aerosol generating article having two mouthpiece ends can facilitate heating a first portion of at least one aerosol-forming substrate and drawing in the aerosol generated through the first mouthpiece element, and then heating a second portion of at least one aerosol-forming substrate and drawing in the aerosol generated through the second mouthpiece element. In other words, by providing an aerosol generating article having two mouthpiece ends, two user experiences can be facilitated with a single aerosol generating article.

[0068] At least one aerosol-forming substrate may be a single aerosol-forming substrate positioned between the first mouthpiece element and the second mouthpiece element.

[0069] The aerosol generating article may include a first susceptor element positioned within an aerosol-forming substrate and a second susceptor element also positioned within the aerosol-forming substrate. Advantageously, positioning the first and second susceptor elements within the aerosol-forming substrate facilitates separate induction heating of the first and second portions of the aerosol-forming substrate. For example, the aerosol generating article may be inserted into an aerosol generator such that only one of the first and second susceptor elements is positioned within the inductor coil. Advantageously, this facilitates heating of different portions of the aerosol-forming substrate during different user experiences.

[0070] Preferably, the aerosol-generating article defines a longitudinal axis extending between a first end and a second end, and the first susceptor element and the second susceptor element are spaced apart from each other in the longitudinal axis direction.

[0071] At least one aerosol-forming substrate may include a first aerosol-forming substrate and a second aerosol-forming substrate. Advantageously, by providing the first and second aerosol-forming substrates separately, it is possible to enable heating of the first aerosol-forming substrate during the first user experience and heating of the second aerosol-forming substrate during the second user experience.

[0072] The first aerosol-forming substrate may be positioned between the first mouthpiece element and the second aerosol-forming substrate. The first aerosol-forming substrate may be in contact with the second aerosol-forming substrate. The first aerosol-forming substrate may be spaced apart from the second aerosol-forming substrate.

[0073] Preferably, the aerosol-generating article defines a long axis extending between the first end and the second end. The first aerosol-forming substrate and the second aerosol-forming substrate may be spaced apart from each other in the long axis direction.

[0074] The aerosol generating article may include a first susceptor element positioned within a first aerosol-forming substrate and a second susceptor element positioned within a second aerosol-forming substrate. Advantageously, providing the first susceptor element within the first aerosol-forming substrate and the second susceptor element within the second aerosol-forming substrate facilitates separate induction heating of the first and second aerosol-forming substrates. For example, the aerosol generating article may be inserted into an aerosol generator such that only one of the first and second aerosol-forming substrates is positioned within the inductor coil. Advantageously, this facilitates heating of each aerosol-forming substrate during different user experiences.

[0075] According to another aspect of the present disclosure, an aerosol-generating article is provided. The aerosol-generating article may comprise at least one aerosol-forming substrate. The aerosol-generating article may comprise at least one mouthpiece element. The aerosol-generating article may comprise a wrapper. The wrapper may be wrapped around at least one aerosol-forming substrate and at least one mouthpiece element. The aerosol-generating article may include a plurality of marks on the outer surface of the wrapper. The aerosol-generating article may include a first end, a second end, and a longitudinal axis extending between the first end and the second end. The plurality of marks may be spaced apart from each other in the longitudinal axis direction.

[0076] According to another aspect of the present disclosure, an aerosol-generating article is provided, comprising at least one aerosol-forming substrate, at least one mouthpiece element, and a wrapper wound around the at least one aerosol-forming substrate and the at least one mouthpiece element. The aerosol-generating article also includes a plurality of marks on the outer surface of the wrapper. The aerosol-generating article includes a first end, a second end, and a longitudinal axis extending between the first end and the second end. The plurality of marks are spaced apart from each other in the longitudinal axis direction.

[0077] Advantageously, multiple spaced-out marks can provide the user with a visual indication of how far the aerosol-generating article has been inserted into the cavity of the aerosol generator. For example, the user may insert the aerosol-generating article into the cavity of the aerosol generator until the selected mark aligns with a portion of the housing of the aerosol generator. This may be particularly advantageous in arrangements in which the aerosol-generating article can be inserted into the aerosol generator in multiple different positions or orientations to facilitate selective heating of a portion of a single aerosol-forming substrate for selective heating of separate aerosol-forming substrates.

[0078] Multiple signs can include any appropriate number of signs. For example, multiple signs can include two, three, four, five, or six signs.

[0079] Preferably, each mark surrounds a portion of the wrapper. Advantageously, providing marks surrounding a portion of the wrapper can facilitate the visibility of each mark regardless of the rotational orientation of the aerosol-generating article.

[0080] The marks may be substantially identical to each other.

[0081] Preferably, at least two of the marks include at least one of different sizes, different shapes, different colors, and different motifs. Preferably, each of the marks includes at least one of different sizes, different shapes, different colors, and different motifs. Advantageously, providing the marks with at least one of different sizes, different shapes, different colors, and different motifs may help the user distinguish between different marks.

[0082] The distance along the long axis between adjacent marks can be 5 to 10 millimeters.

[0083] The aerosol-generating article may also be an aerosol-generating article according to any of the embodiments described herein or any other aspect of the disclosure. In other words, the aerosol-generating article may include any combination of features from one or more other aspects of the disclosure.

[0084] Each of the aerosol-forming substrates described herein may comprise a tobacco plug.

Optionally, the tobacco plug may also comprise capsules containing, for example, additional tobacco or non-tobacco volatile flavor compounds. Such capsules may melt during heating of the tobacco plug. Alternatively, or additionally, such capsules may be crushed before, during, or after heating of the tobacco plug. Optionally, the tobacco plug may comprise one or more plant components.

[0085] If the tobacco plug contains homogenized tobacco material, the homogenized tobacco material may be formed by agglutinating particulate tobacco. The homogenized tobacco material may be in the form of a sheet. The homogenized tobacco material may have an aerosol-forming content greater than 5 percent by dry weight. Alternatively, the homogenized tobacco material may have an aerosol-forming content of 5 to 30 percent by weight by dry weight. The homogenized tobacco material sheet may be formed by agglutinating particulate tobacco obtained by crushing one or both of tobacco leaf laminas and tobacco leaf stems, or by other means of fine crushing, and alternatively, or additionally, the homogenized tobacco material sheet may contain one or more of the following: tobacco dust, tobacco fines, and other particulate tobacco by-products formed during tobacco processing, handling, and transport. The homogenized tobacco material sheet may contain one or more intrinsic binders (i.e., endogenous tobacco binders), one or more exogenous binders (i.e., exogenous tobacco binders), or a combination thereof, to assist in agglutinating particulate tobacco. Alternatively, or additionally, the homogenized tobacco material sheet may contain other additives, including but not limited to tobacco and non-tobacco fibers, aerosol formers, wetting agents, plasticizers, flavoring agents, fillers, aqueous and non-aqueous solvents, and combinations thereof. The homogenized tobacco material sheet is preferably formed by a casting process of a type that generally includes casting a slurry containing particulate tobacco and one or more binders onto a conveyor belt or other support surface, drying the cast slurry to form a homogenized tobacco material sheet, and removing the homogenized tobacco material sheet from the support surface.

[0086] Each cigarette plug may have a length of 10 to 18 millimeters. Each cigarette plug may have a length of 12 to 16 millimeters.

[0087] Each cigarette plug may have a diameter of 5 mm to 12 mm.

[0101] Herein, embodiments of the present disclosure will be described, for illustrative purposes only, with reference to the attached drawings.

[0102] Figure 1 shows a cross-sectional view of an aerosol generator 10 according to an embodiment of the present disclosure. The aerosol generator 10 comprises a first housing portion 12 and a second housing portion 14 extending from the first housing portion 12. As illustrated by comparing Figures 1 and 4, the second housing portion 14 is connected to the first housing portion 12 such that the second housing portion 14 can be rotated relative to the first housing portion 12. During use of the aerosol generator 10, the user may use the second housing portion 14 as a handle for holding the aerosol generator 10. Thus, the user can rotate the second housing portion 14 to an ergonomically comfortable position.

[0103] The first housing portion 12 defines a cavity 16 for receiving an aerosol-generating article. The first housing portion 12 also defines a first opening 18 at the first end of the cavity 16 and a second opening 20 at the second end of the cavity 16. The first and second openings 18 and 20 are sized so that the aerosol-generating article can be inserted into the cavity 16 through the first opening 18 or the second opening 20.

[0104] The aerosol generator 10 also includes a first closing member 22 that is slidably mounted on the first housing portion 12 and biased toward the closed position shown in Figure 1, where the first closing member 22 covers the first opening 18. The first closing member 22 may be moved to the open position shown in Figure 4, where the first opening 18 is not closed.

[0105] The aerosol generator 10 also includes a second closing member 24 that is slidably mounted on the first housing portion 12 and biased toward the closed position shown in Figure 1, where the second closing member 24 covers the second opening 20. The second closing member 24 may be moved to the open position shown in Figure 4, where the second opening 20 is not blocked.

[0106] The electric heater 26 is located within the first housing portion 12 and includes an inductor coil extending around the central portion of the cavity 16. A power supply 30, comprising a controller 28 and a battery, is located within the second housing portion 14. The controller 28 is configured to supply power from the power supply 30 to the inductor coil in order to inductively heat the aerosol-generating article received within the cavity 16.

[0107] Figures 2 and 3 show an aerosol generating article 50 according to a first embodiment of the present disclosure. The aerosol generating article 50 includes a first mouthpiece element 52 at a first end 54 of the aerosol generating article 50 and a second mouthpiece element 56 at a second end 58 of the aerosol generating article 50. The first and second mouthpiece elements 52 and 56 are each filter elements. An aerosol forming substrate 60 including a cigarette plug is positioned in the center of the aerosol generating article 50 between the first mouthpiece element 52 and the second mouthpiece element 56. An optional first aerosol cooling element 62 is positioned between the first mouthpiece element 52 and the aerosol forming substrate 60. An optional second aerosol cooling element 64 is positioned between the second mouthpiece element 56 and the aerosol forming substrate 60.

[0108] The aerosol generating article 50 also includes a first susceptor element 66 located within a first portion of the aerosol forming substrate 60 and a second susceptor element 68 located within a second portion of the aerosol forming substrate 60. The first and second susceptor elements 66 and 68 are spaced apart from each other in the longitudinal axis direction 70 of the aerosol generating article 50.

[0109] The wrapper 72 is wrapped around the first and second mouthpiece elements 52, 56, the aerosol-forming substrate 60, and the first and second aerosol cooling elements 62, 64. A plurality of marks are provided on the outer surface of the wrapper 72, and the plurality of marks include a first mark 74, a second mark 76, and a third mark 78 that are spaced apart from each other in the longitudinal direction 70. Each mark includes a printed line extending around the wrapper 72. In the illustrated embodiment, each mark includes a different printed line to help the user distinguish between different marks. However, it will be understood that the marks may be substantially identical to each other. For example, the first, second, and third marks 74, 76, 78 may include three identical printed lines spaced apart from each other in the longitudinal direction 70.

[0110] Figures 4-9 show an aerosol generating system 100 comprising the aerosol generator 10 of Figure 1 and the aerosol generating article 50 of Figures 2 and 3. The first and second closing members 22, 24 are moved to their open position to allow insertion of the aerosol generating article 50 into the cavity 16 defined by the first housing portion 12. Advantageously, the biasing of the first and second closing members 22, 24 to their closed position biases the first and second closing members 22, 24 relative to the aerosol generating article 50, thereby holding the aerosol generating article 50 within the cavity 16.

[0111] Advantageously, the first and second mouthpiece elements 52, 56, the first, second, and third marks 74, 76, 78, and the first and second susceptor elements 66, 68 facilitate the use of the aerosol generating article 50 having the aerosol generating device 10 in a number of different configurations.

[0112] In the first configuration shown in Figures 4 and 5, the user inserts the aerosol generating article 50 into the cavity 16 until the first mark 74 aligns with the edge of the first housing portion 12. In this configuration, the entire aerosol forming substrate 60, as well as both the first and second susceptor elements 66, 68, are positioned within the inductor coil. Thus, in the first configuration, the electric heater 26 heats the entire aerosol forming substrate 60, and the user may inhale the generated aerosol through either the first mouthpiece element 52 or the second mouthpiece element 56.

[0113] In the second configuration shown in Figures 6 and 7, the user inserts the aerosol generating article 50 into the cavity 16 until the second mark 76 aligns with the edge of the first housing portion 12. In this configuration, only the first portion of the aerosol forming substrate 60 and the first susceptor element 66 are positioned within the inductor coil. Therefore, in the second configuration, the electric heater 26 heats only the first portion of the aerosol forming substrate 60, and the user may inhale the generated aerosol through the first mouthpiece element 52.

[0114] In the third configuration shown in Figures 8 and 9, the user inserts the aerosol generating article 50 into the cavity 16 until the third mark 78 aligns with the edge of the first housing portion 12. In this configuration, only the second portion of the aerosol forming substrate 60 and the second susceptor element 68 are located within the inductor coil. Therefore, in the third configuration, the electric heater 26 heats only the second portion of the aerosol forming substrate 60, and the user may inhale the generated aerosol through the second mouthpiece element 56.

[0115] In the second and third configurations, the user can use the aerosol generating article 50 for two user experiences, but in each experience, only half of the aerosol forming substrate 60 is used. The user may use the third configuration after the second configuration. Alternatively, the user may use the second configuration after the third configuration.

[0116] Figures 10-11 show an alternative aerosol-generating article 150 according to a second embodiment of the present disclosure. The aerosol-generating article 150 is substantially the same as the aerosol-generating article 50 shown in Figures 2 and 3, and similar reference numerals are used to indicate similar parts.

[0117] The aerosol generating article 150 differs from the aerosol generating article 50 in the arrangement of the aerosol forming substrate. In particular, the aerosol generating article 150 includes a first aerosol forming substrate 160, which includes a first cigarette plug on which a first susceptor element 66 is positioned, and a second aerosol forming substrate 161, which includes a second cigarette plug on which a second susceptor element 68 is positioned. Those skilled in the art will understand that the separate first and second aerosol forming substrates 160, 161 correspond to the first and second parts of the single aerosol forming substrate 60 of the aerosol generating article 50. Thus, the aerosol generating article 150 can be used with the aerosol generating device 10, just like the aerosol generating article 50.

[0118] Figures 12 and 13 show an aerosol generating article 250 according to a third embodiment of the present disclosure. The aerosol generating article 250 includes a mouthpiece element 52 at a first end 54 of the aerosol generating article 250. The mouthpiece element 52 is a filter element. The first end 54 forms the mouth end or downstream end of the aerosol generating article 250. An optional porous element 256 is located at a second end 58 of the aerosol generating article 250. The second end 58 forms the upstream end of the aerosol generating article 250. An aerosol forming substrate 60, including a cigarette plug, is located between the mouthpiece element 52 and the porous element 256. An optional aerosol cooling element 62 is located between the mouthpiece element 52 and the aerosol forming substrate 60. A susceptor element 66 is located within the aerosol forming substrate 60 and extends along the long axis 70 of the aerosol generating article 250.

[0119] The wrapper 72 is wrapped around the mouthpiece element 52, the porous element 256, the aerosol-forming substrate 60, and the aerosol cooling element 62. Marks 74, including printed lines, are provided on the outer surface of the wrapper 72.

[0120] Figures 14-16 show different configurations of the aerosol generating system 300, including the aerosol generator 10 of Figure 1 and the aerosol generating article 250 of Figures 12 and 13. The first and second closing members 22, 24 are moved to their open positions to allow insertion of the aerosol generating article 250 into the cavity 16 defined by the first housing portion 12. Advantageously, biasing the first and second closing members 22, 24 to the closed position biases the first and second closing members 22, 24 relative to the aerosol generating article 250, and holds the aerosol generating article 250 within the cavity 16.

[0121] In each configuration of the aerosol generating system 300, the user inserts the aerosol generating article 250 into the cavity 16 until the mark 74 aligns with the edge of the first housing portion 12. In this position, the entire aerosol forming substrate 60 and the susceptor element 66 are positioned within the inductor coil. Thus, the electric heater 26 heats the entire aerosol forming substrate 60, and the user can inhale the generated aerosol through the mouthpiece element 52.

[0122] As illustrated with reference to Figure 1, the second housing portion 14 of the aerosol generator 10 functions as a handle and may be rotated relative to the first housing portion 12. Therefore, advantageously, the user may rotate the second housing portion 14 to an ergonomically comfortable position. For example, Figure 14 shows a first configuration in which the second housing portion 14 extends substantially perpendicular to the longitudinal axis of the aerosol generating article 250 received within the cavity 16 of the first housing portion 12. Figure 15 shows a second configuration in which the second housing portion 14 is angled away from the mouth end of the aerosol generating article 250. Figure 16 shows a third configuration in which the second housing portion 14 is angled toward the mouth end of the aerosol generating article 250. It should be understood that the configurations shown in Figures 14, 15, and 16 are merely illustrative, and the user may rotate the second housing portion 14 to any ergonomically comfortable position relative to the first housing portion 12.
