    [001] The invention relates to an aerosol generating device with an external cross section defined by a shape that has at least 5 sides. The invention also relates to a system comprising the aerosol generating device and a charging device for receiving the aerosol generating device.
    [002] Aerosol generating articles in which an aerosol deformation substrate, such as a tobacco-containing substrate, is heated rather than being burned as is known in the art. The purpose of such heated aerosol generation articles is to reduce the known harmful smoke constituents produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes. Typically, in such heated aerosol generating articles, an inhalable aerosol is generated by transferring heat from a heat source to a physically separate substrate or aerosol-forming material, which can be located inside, around or downstream of the heat source. During consumption, volatile compounds are released from the aerosol-forming substrate by transferring heat from the heat source and entrained in the extracted air through the aerosol generating article. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    [003] A series of prior art documents presented aerosol generation devices for the consumption of heated aerosol generation articles. Such devices include, for example, heated smoking systems and electrically heated smoking systems and smoking articles that contain a tobacco-based aerosol-forming substrate consumed when using such systems.
    [004] It would be desirable to provide an aerosol generating device that is ergonomic to maintain in use. It would also be desirable to provide a device such that it remains stationary when not in use, for example, an aerosol generating device that resists rolling when supported on a flat surface.
    [005] It is also known in the prior art to provide a secondary device for charging the aerosol generating device while the aerosol generating device is not in use, indicated herein as a charging device or secondary device. The provision of such a loading device allows the aerosol generating device to be smaller and lighter. The loading device may also provide a means for storing information related to the use of the aerosol generating device that is discharged from the aerosol generating device when coupled with the loading device. If the connections between the connections of an aerosol generating device are incorrectly coupled to the contacts of a secondary device, such as a charging device, damage to the electronic components within one or both devices may occur.
    [006] It would be desirable to provide an aerosol generating system that comprises an aerosol generating device and a secondary device for charging the aerosol generating device that reduces the possibility of incorrectly connecting the aerosol generating device to the secondary device.
    [007] As used herein, an 'aerosol generating device' refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol forming substrate can be part of an aerosol generating article, for example, part of a smoking article. An aerosol generating device may comprise one or more components used to supply energy from a power source to an aerosol-forming substrate to generate an aerosol. For example, an aerosol generating device may be a heated aerosol generating device. An aerosol generating device may be an electrically heated aerosol generating device or a gas heated aerosol generating device. An aerosol generating device can be a smoking device that interacts with an aerosol forming substrate of an aerosol generating article to generate an aerosol that is directly inhaled into a user's lungs through the user's mouth.
    [008] As used herein, the term 'aerosol-forming substrate' refers to a substrate with the ability to release volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. As an alternative to heating or combustion, in some cases volatile compounds can be released by a chemical reaction or by a mechanical stimulus, such as ultrasound. An aerosol-forming substrate can be solid or liquid or can comprise solid and liquid components. An aerosol-forming substrate can be adsorbed, coated, impregnated, or else loaded onto a carrier or support. An aerosol-forming substrate can conveniently make part of an aerosol generating article or a smoking article.
    [009] An aerosol-forming substrate may comprise nicotine. An aerosol-forming substrate may comprise tobacco, for example, it may comprise a tobacco-containing material that contains volatile tobacco flavor compounds, which are released from the aerosol-forming substrate upon heating. In preferred embodiments, an aerosol-forming substrate may comprise homogenized tobacco material, for example, molded sheet tobacco. An aerosol-forming substrate may comprise at least one aerosol former, such as propylene glycol or glycerin.
    [0010] As used herein, the terms 'aerosol generating article' and 'smoking article' refer to an article comprising an aerosol-forming substrate that has the ability to release volatile compounds that can form an aerosol . For example, an aerosol generating article may be a smoking article that generates an aerosol that is directly inhaled into a user's lungs through the user's mouth. An aerosol generating article may be disposable. The term ‘aerosol generation article’ is used in general from now on.
    [0011] Preferably, an aerosol generating article is a heated aerosol generating article, which is an aerosol generating article comprising an aerosol forming substrate that is intended to be heated rather than burned in order to to release volatile compounds that can form an aerosol. The aerosol formed by heating the aerosol-forming substrate may contain less known harmful constituents than must be produced by combustion or by the pyrolytic degradation of the aerosol-forming substrate. An aerosol generating article may be or may comprise a tobacco rod.
    [0012] In one aspect, an elongated aerosol generating device is provided in which at least part of the device has an external cross section defined by a shape having at least five sides. It is preferred that the aerosol generating device has a high aspect ratio and that a substantial proportion of the length has a defined cross section. The entire length of the device can have a defined cross section.
    [0013] The external cross section can be a polygonal cross section. The polygon comprises at least five sides. The polygon can comprise at least six sides.
    [0014] The device can be more than 60 mm in length. The device can be less than 150 mm in length. For example, the device can be between 80 mm and 120 mm in length. The device can be between 90 mm and 110 mm in length.
    [0015] An external circumference of the cross-sectional shape may have a diameter of more than 10 mm. An external circumference of the cross-sectional shape can have a diameter of less than 20 mm. An external circumference of the cross-sectional shape can have a diameter between 12 mm and 16 mm. The cross section of a polygon can be defined by the line that passes from one edge of the polygon, through the center of the polygon, and up to an opposite edge. The length of this line can be between 10 mm and 20 mm, preferably between 12 mm and 15 mm. A polygon with equal sides can have a line in cross section that passes from a flat face of the polygon to an opposite flat face of the polygon. This distance can be, for example, between 12 mm and 14 mm. A polygon with equal sides can have a line in cross section that passes from one corner of the polygon to an opposite corner of the polygon. This distance can be, for example, between 12 mm and 14 mm. The cross section from corner to corner will be slightly longer than the face to face cross section.
    [0016] All sides of the shape in cross section can be the same length. The sides of the cross-sectional shape can be of different lengths. Preferably, one or more sides are more than 2 mm in length, preferably more than 3 mm or more than 4 mm. It may be advantageous for one or more sides to be more than 5 mm long. The length of one side of the cross-sectional shape can be the same as the width of a facet of the three-dimensional device. For example, if the device is substantially cylindrical and has a cross section that is an equilateral hexagon with sides 5 mm long, the device will have six longitudinal facets 5 mm wide.
    [0017] The cross-sectional shape preferably has at least five corners joined by straight or curved lines to form the shape that has at least five sides. Where corners are joined by curves, it is preferable that the curves have a large radius compared to the length of the side so that the side only deviates slightly from the linear and gives the appearance of being almost flat.
    [0018] The aerosol generating device can be substantially cylindrical. The term cylindrical as used herein describes a three-dimensional shape that has substantially parallel sides and a base defined by a two-dimensional shape. The two-dimensional shape is that defined for the cross section, that is, a shape that has at least five sides. The term cylinder as used herein can be equivalent to the term prismatic. Substantially parallel means that the sides do not have to be precisely parallel. For example, the sides can be within about 5 degrees from the true parallel.
    [0019] A part of the aerosol generating device can be molded as an elongated truncated pyramid that has converging sides and a base defined by a two-dimensional shape. The two-dimensional shape is that defined for the cross section, that is, a shape that has at least 5 sides.
    [0020] Preferably, each side of the two-dimensional shape that define the cross section corresponds to an elongated face on an external surface of the device.
    [0021] With the provision of an aerosol generating device with such a shape in a multifaceted cross section, the surface area of the device is increased compared to a device that has a circular cross section. For example, a device that is substantially cylindrical and has a polygon-shaped cross section with at least 5 sides advantageously provides a user with a more ergonomic feel, while increasing the stability of the device when it is placed on a surface while not in use. in use. It is anticipated that a user may wish to place the device on a flat surface, for example, a table. If the device has to roll, this may be inconvenient for the user. A device that understands the characteristics of the shape that help to stabilize the device and resist rolling will be advantageous.
    [0022] The shape in cross section, for example, a polygon, can comprise between 6 and 16 sides, preferably between 7 and 12 sides. In a preferred embodiment, the shape is a polygon that comprises 10 sides.
    [0023] The polygon can be a regular polygon. The term polygoregular refers to a polygon that is equiangular, in which all angles are equal, and equilateral, on all sides are of the same length. The sides can be straight or slightly curved. The angles can be formed by sharp corners or rounded corners. The aerosol generating device may have a regular polygonal cross section along its entire length. Alternatively, the aerosol generating device may have a regular polygonal cross section that extends over only a part of its length. For example, the cross section of the aerosol generating device may change due to the presence of a button. Such a button can be adapted to activate the device in use. The position of the button can be chosen to facilitate the presentation of the button on a higher surface regardless of the shape of the device.
    [0024] As used herein, the term "length" refers to the dimension in the longitudinal direction. The term "longitudinal" refers to the main axis of the elongated aerosol generating device. As used herein, the term "transverse" refers to a direction perpendicular to the longitudinal direction.
    [0025] At least one end of the aerosol generating device can be tapered. Alternatively, both ends of the aerosol generating device can be tapered. Preferably, the radius of or each end face of the tapered end is at least 50% of the maximum radius of the aerosol generating device. The radius of a polygon is measured from the centroid of the polygon to a vertex of it.
    [0026] Where at least one end of the aerosol generating device is tapered, preferably at least one end of the aerosol generating device is tapered over at least about 5% of the length of the device. More preferably, at least one end of the aerosol generating device is tapered over at least about 7% of the length of the device. Even more preferably, at least one end of the aerosol generating device is tapered over at least about 7.5%.
    [0027] Where at least one end of the aerosol generating device is tapered, the taper can be linear or curved. The presence of a taper can be particularly advantageous where one end of the device is configured to be inserted into and coupled with another device. For example, one or more electrical contacts can be located at or near a first end of the device in such a way that they can be placed in contact with the electrical contacts located within a receiving cavity of another device. A tapered end of the device, together with a coupling receiving part, allows the device to be coupled quickly and easily by a user. The taper guides the device to a correct position within the receiving cavity. Due to the guide effect provided by the taper, it is possible for a user to couple the device to another device, for example, a load unit, without looking at the device to align the contacts. This can be advantageous, since the act of attaching the device to another device can be performed in the dark or when a user is engaged in a conversation.
    [0028] The user of an aerosol generating device may want to support the device on a surface while consuming an aerosol generating article. It may be undesirable to support the device when one end of the mouth of the article can then come in close contact with the surface, which can be unhygienic. It may be preferable to tilt the device in such a way that the mouth end of the article is raised from the surface. Advantageously, the presence of a taper can facilitate the inclination of the device in contact with the surface and the stationary object raised above the surface. The taper, in conjunction with a formed cross section, causes a large surface area to come into contact with the surface when the device is tilted at an appropriate angle. This can increase the stability of the device when it is tilted at an angle. The ideal tilt angle may depend on the taper angle. An ideal angle of inclination can, for example, be between 25 degrees and 60 degrees in relation to the surface.
    [0029] Preferably, the elongated aerosol generating device comprises an outer shell that has a substrate receiving cavity adapted to receive an aerosol generating article that includes an aerosol forming substrate, an adapted heating element to heat an aerosol forming substrate to generate an aerosol, and a power source adapted to supply energy to the heating element. The device may also comprise a controller for controlling the energy supplied from the power supply to the heating element.
    [0030] Where the aerosol generating device comprises a substrate receiving cavity, a support may be provided within the cavity. The support is adapted to maintain an aerosol forming substrate adjacent to the end of the aerosol generating device that has the cavity. The aerosol forming substrate itself is preferably a component part of an aerosol generating article that can be received on the support.
    [0031] The external shape of the device can be defined by an enclosure. The housing may form a housing that holds the component parts of the device. The housing can have an internal cross section that is the same shape as its external cross section. The housing may have an internal cross section that is circular. The housing may have an internal cross section that is non-circular and of a different shape than the external cross section.
    [0032] Where the device comprises a support adapted to hold an aerosol generating article that includes an aerosol-forming substrate, a plurality of air inlets that lead to a plurality of air channels within the device can be formed by a space between the support and the outside of the enclosure. For example, the support may have a circular outer cross section and the enclosure may have a decagonal inner cross section. If the support is fitted inside the enclosure in such a way that an external part of the support contacts each of the ten internal faces of the inner surface of the enclosure, ten openings are defined by spaces between the corners of the decagon and the support. These openings can act as air intakes. The area of the air inlets can be controlled by selecting the internal shape of the enclosure, or by selecting the internal shape of the enclosure in the part of the enclosure that defines the substrate receiving cavity.
    [0033] The air channels can diverge away from the air inlets inside the device since the outer shell diverges with the taper. The provision of such air channels can improve air entrainment within the device. In addition, entrained air can improve the insulation between the aerosol-forming substrate and the outer shell.
    [0034] The substrate receiving cavity can be adapted to receive an aerosol generating article which has an end of the mouth and a distal end, and an aerosol forming substrate which is located at the distal end. The distal end of the aerosol generating article is inserted into the substrate receiving cavity.
    [0035] In use, a user inserts an aerosol generating article into the substrate receiving cavity of the device, activates the device, applies his lips to the mouth end of the aerosol generating article, and inhales. Air and any aerosol generated within the device are extracted through the mouth end of the aerosol generating article to be inhaled by the user. When the user inhales, air and aerosol move through the aerosol generating article from the distal end to the mouth end. In some embodiments, air can be drawn into the device by extremally shaking the device proximal to the aerosol generating article. In some embodiments, air can be drawn into the device through a side wall. In other embodiments, air can be drawn into the device through a combination of the proximal end of the device and a side wall of the device.
    [0036] The aerosol generating article may be substantially cylindrical in shape. The aerosol generating article can be substantially elongated. The aerosol generating article may also have a length and circumference substantially perpendicular to the length. The aerosol generating article may be received in the cavity of the aerosol generating device in such a way that the length of the aerosol generating article is substantially parallel to the direction of the air flow in the aerosol generating device.
    [0037] Where the aerosol generating device has a wrap, the wrap can be an elongated wrap that has a length between 60 mm and 150 mm. The enclosure can have a wall thickness between 0.2 mm and 1 mm. If the enclosure is made of a metallic material, the wall thickness is preferably between 0.2 mm and 0.4 mm. If the shell is made of a polymer, the wall thickness is preferably between 0.5 mm and 1 mm, for example, between 0.6 mm and 0.8 mm, or about 0.75 mm.
    [0038] The outer casing of the aerosol generating device may be manufactured from two, four or more parts. The parts are preferably joined to each other along a cross section of the device, and can be adapted to be joined around one or more buttons protruding from the device. Where the outer shell comprises four parts, the parts may be two tapered end parts, and two substantially cylindrical center parts. In some embodiments, a first part of the housing may define the external shape of a first end of the device and a second part of the housing may define the external shape of a second end of the device. Two adjacent parts of the enclosure can meet at a junction located about halfway along the length of the device. Two parts of the housing can meet at a junction that is closer to one end of the device than the other. Preferably, the parts of the housing are separable, for example, a first part of the housing can be separated from a second part of the housing by sliding the parts of the housing away from each other in a longitudinal direction. Access to an internal part of the device can be obtained by removing one or more parts of the housing.
    [0039] It may be preferable for the aerosol generating device to comprise a part of the housing that is attached to the internal components of the device, and cannot be removed from the device, and an additional part of the housing that can be removed from the device. It may be preferable that one end of the device comprising the substrate receiving cavity can be removable from the device. Any support within the substrate receiving cavity can be removed with the housing part. Removing a part of the housing may be desirable in order to access the internal component parts of the device, for example, to clean the device. The movement of a part of the wrapper, or the removal of a part of the wrapper, may also be desirable in order to assist in the removal of aerosol generating articles after using the device.
    [0040] Where a part of the enclosure is removable from the device, it may be desirable that the part of the enclosure can only be attached to the device in a specific orientation. The removable part of the housing can, for example, slide over a substantially cylindrical internal part of the device. In such circumstances, an inner surface of the enclosure may define a notch or protuberance that engages with a corresponding protuberance or notch on the inner part to ensure that the enclosure part can only be coupled to the aerosol generating device in a specific orientation.
    [0041] Where a part of the casing is slidable with respect to the internal components of the device, it may be advantageous that the part of the casing can be retained in one or more stable positions. For this purpose, the inner surface of the housing part may comprise protrusions that mate with a defined protrusion in an internal part of the device to act as compressors. For example, two longitudinally spaced protrusions on the inner surface can couple with a protrusion on the inner part of the device to locate the housing part. Preferably, the protrusion on the inside protrudes in such a way that it can be caused to pass the protrusions in the enclosure with the application of a force. It can be particularly advantageous that the inner surface of the enclosure has a non-circular cross-sectional shape, for example, a polygonal shape. With the location of the protuberances on the corners of the inner surface of the enclosure, it is possible to control the properties of the compressors to optimize their function. A removable part of the enclosure may have a set of compressors that hold the part of the enclosure in an entirely closed position adjacent to a second part of the enclosure. There may be a second set of compressors that retain the part of the housing in a second position that is slidably removed from the first position, but still attached to the device. The relative strength of different compressor sets can be varied.
    [0042] Where an outer casing comprises two or more separate parts, the visual appearance of the device can be damaged if the two or more parts do not align accurately. For example, if the device is in the shape of a cylinder that has a polygonal base, any mismatch or misalignment between adjacent parts of the enclosure will be immediately apparent when the parts of the enclosure are put together. This can be a result of light reflecting at different angles to the substantially flat longitudinal faces defined on the outer surface of the enclosure. If the longitudinal faces are not perfectly flat, however, the visual problem may not be as visible. For example, if the device has a polygonal cross section, and the polygon faces are very slightly curved outward, the longitudinal faces of the device will have a slightly transverse curvature. This slight curvature produces an optical effect that can disguise imperfect alignments between adjacent parts of the enclosure, which may not be as visible as if the faces were perfectly flat. Although some curvature may be desirable, it is preferable that no convex curvature is not sufficient to facilitate the rolling of the device. Thus, it is preferable that any curve that delineates a face in the external cross section of the device has a radius that is substantially greater than the distance across the face. In this way, the device can be both aesthetically pleasing, have a pleasant ergonomic feel, and have an external shape that provides stability against the bearing.
    [0043] The outer shell of the aerosol generation system can be manufactured from any material or appropriate combination of materials. Examples of suitable materials include, but are not limited to, metallic materials and metals, alloys, polymers and plastics, or composite materials containing one or more of these materials, or thermoplastics that are suitable for food or pharmaceutical applications, for example example, polypropylene, polyether ether ketone (PEEK) and polyethylene. Preferred materials can include aluminum and aluminum alloys, acrylonitrile butadiene and styrene (ABS), and polycarbonate (PC). When a metal, metallic material, or composite material comprising a metal is used, the surface can be anodized or otherwise treated to improve the appearance and provide a scratch-resistant surface for the device housing. Similarly, when the material does not comprise a metal, a metallic material or a composite material, the materials can be selected to optimize the appearance and functionality, for example, scratch resistance, of the shell.
    [0044] In an additional aspect, an aerosol-generating system is also provided. The system comprises an elongated aerosol generating device as described above, and a loading device comprising a cavity having an appropriate opening for receiving the aerosol generating device.
    [0045] Preferably, the aerosol generating device comprises a means for coupling the aerosol generating device to the receiving cavity of the loading device. The coupling means can comprise at least one notch to receive at least one corresponding protuberance in the aerosol generating device. At least one bump can be a button adapted to activate the aerosol generating device. Alternatively, the button on the device itself can function as the protrusion that facilitates coupling. The aerosol generating device receiving the cavity may have a cross-sectional shape that corresponds to the cross-sectional shape of the aerosol generating device. The coupling means can then result from an enhanced orientation relationship between the aerosol generating device and the receiving cavity.
    [0046] In an embodiment in which the aerosol generating device comprises at least one tapered end, the tapered end allows the device to be inserted more easily into the cavity of the loading device.
    [0047] As used herein, the means plus the characteristics of the function can be expressed alternatively in terms of their corresponding structure.
    [0048] Any feature related to one aspect can be applied to other aspects, in any appropriate combination. In particular, aspects of the method can be applied to aspects of the apparatus, and vice versa. In addition, any, some or all of the characteristics in one aspect can be applied to any, some or all of the characteristics in any other aspect, in any appropriate combination.
    [0049] It should also be appreciated that the particular combinations of the various characteristics described and defined in all aspects of the invention can be implemented or provided or used independently.
    [0050] These and other aspects of the apparatus will become apparent from the following exemplary modalities that are described with reference to the following Figures, in which:
    [0051] Figure 1 shows a perspective view of an embodiment of an aerosol generating device;
    [0052] Figure 2 shows a side view of the aerosol generating device shown in Figure 1;
    [0053] Figures 3 (a) and 3 (b) show end views of the aerosol generation device shown in Figures 1 and 2;
    [0054] Figures 4 (a) and 4 (b) illustrate a schematic diagram of the air flow through the aerosol generating device shown in Figures 1, 2 and 3;
    [0055] Figure 5 shows an exploded view of the aerosol generating device shown in Figures 1, 2 and 3;
    [0056] Figures 6 (a) and 6 (b) illustrate a charging device adapted to receive and charge the aerosol generating device shown in Figures 1 to 5;
    [0057] Figure 7 shows a schematic side view of a second embodiment of an aerosol generating device;
    [0058] Figure 8 illustrates the decagonal-convex external cross section of the device of Figure 7;
    [0059] Figures 9A and 9B are schematic diagrams that illustrate the use of compressors defined on an internal surface of a part of the enclosure to retain the part of the enclosure in the device;
    [0060] Figure 10 is a schematic cross-sectional illustration of an internal surface of a part of the housing showing the circumferential position of the compressors of Figure 9; and
    [0061] Figure 11 is a schematic illustration showing a tapered aerosol generating device that is inserted into a cavity in a charging device to make an electrical connection between the contacts located on the aerosol generating device and the charging device, respectively.
    [0062] Figure 1 shows a perspective view of an embodiment of an aerosol generating device 100. The device 100 is elongated and comprises two opposite polygonal end faces 102 and 104, respectively. The device 100 also comprises a button 106 adapted to activate the aerosol generating device when pressed. The operation of the device is described in more detail below. As can be seen, the outer casing of the device 100 comprises four parts joined in the coupling lines 108, 110 and 112, respectively. The outer shell is made of an aluminum alloy that has a wall thickness of about 0.3 mm. The four parts are, respectively, a first tapered end part 114 joined to a first central part 116, a second tapered end part 120 joined to a second central part 118. The four parts fit together around an inner housing (not shown) in a manner described below.
    [0063] Device 100 has a regular polygonal cross section over most of its length. However, in the 106 button region the cross section is no longer a regular polygon, but remains a simple polygon.
    [0064] Figure 2 shows a side view of the aerosol generating device 100 shown in Figure 1. As can be seen, button 106 projects from the surface of the device so that the user can more easily push the button to activate the device in use.
    [0065] Figures 3 (a) and 3 (b) show the polygonal end faces 102 and 104 of the device 100, respectively. As can be seen, the polygon in this modality has ten sides, and this results in a device that has ten faces extended longitudinally. The button 106 has a triangular cross section and protrudes from one side of the housing. This means that there is a flat face on the opposite side of the device for the button and the device can therefore be supported with the button 106 at the highest point. It should be noted that if the device has to have a cross section defined by a polygon with an odd number of sides, it may be preferable for the button to be defined between the faces in such a way that it can be the highest when the device is supported on a surface.
    [0066] Figure 3 (a) shows the end face 102 of the coupling part with five connectors or contacts 300. The connectors 300 can include one or more electrical connectors or one or more data connectors or a combination of electrical connectors and connectors of data. The end face is part of an internal component of the device that is retained within the housing. The electrical connectors are adapted to connect with a secondary charging device which is described in more detail below. As can be seen, the provision of a polygonal cross section allows the five electrical connectors 300 to be more easily positioned on the end face 102 of the aerosol generating device 100.
    [0067] Figure 3 (b) shows the end face 104. A support 402 defining a cavity 302 is provided to accept an aerosol generating article comprising an aerosol forming substrate (not shown).
    [0068] Figures 4A and 4B show a schematic representation of the air flow through the device. It should be noted that these Figures do not accurately illustrate the relative range of the device elements, for example, the input channels. As can be seen in this embodiment, when an aerosol generating article 304 is received inside the cavity 302 of the device 100 (Figure 4B), the air drawn into the device passes around the outside of an aerosol generating support 402 of the article located inside the cavity 302. The support 402 has a circular cross section. The extracted air proceeds to the aerosol forming substrate at the distal end of the smoking article adjacent to a heating plug 404 of a blade-shaped heating element 406 provided in cavity 302. The extracted air continues through the substrate, dragging the aerosol, and then to the mouth end of the smoking article. The air intakes 408 formed between the outer shell and the support 402 allow air to be drawn more efficiently and assist in the isolation of the heated aerosol generating article from the outer shell. Air intakes 408 can be seen schematically in Figure 3 (b). It should be noted that the entries may not be circular, but are illustrated as circular in Figure 3 (b) for clarity.
    [0069] Figure 5 shows an exploded view of the aerosol generating device 100. The device comprises a first outer part 500 of the housing comprising the first tapered end part 114 and the first central part 116. The device also comprises a second outer part 502 of the housing comprising the second tapered end part 120 and the second central part 118. The device also comprises an inner housing 504. The device also comprises a power supply in the form of a battery 506, a controller 508 adapted to control the energy supplied by battery 506 to a heating element (not shown) contained in an internal section 510 of the housing. The button 106 is located in the central part 504 of the enclosure, and couples with the controller 508 to allow the user to activate the device.
    [0070] In use, a user inserts an aerosol generating article 516 which comprises an aerosol forming substrate 512 into cavity 302 of the aerosol generating device 100. The aerosol forming substrate 512 couples with the heating element 406 When the user activates the device by pushing the button 106, battery power 506 is applied to the heating element 406 through the controller 508. The heating element 406 heats the aerosol forming substrate 512 to generate an aerosol and the aerosol it is dragged into the air flow while the user extracts at the mouth end 514 of the aerosol generating article 516.
    [0071] Figure 6A shows a perspective view of a loading device 600 adapted to receive and load the aerosol generating device 100. The loading device comprises a cavity 602 adapted to receive the aerosol generating device 100, a power supply in the form of a battery 604, and a controller 606. When device 100 requires charging or data must be communicated between devices 100 and 600, device 100 is inserted into cavity 602, and connections 300 they are coupled to the corresponding contacts 608 of contact plate 610 at the bottom of cavity 602. Figure 6B is a schematic diagram illustrating contact plate 610 of the loading device, which is located at the bottom of cavity 602. The contact plate can be seen as having five contacts 608, which correspond to the five contacts 300 in the aerosol generating device.
    [0072] The cavity 602 has a polygonal cross section that corresponds to the cross section of the aerosol generating device 100. The cavity may alternatively have a substantially circular cross section with a diameter sufficient to receive the device. In addition, the cavity is provided with a notch 612 that allows the button 106 of the device to be located within the cavity 602. The button 106 on the device 100 allows the device to be coupled to the loading device 600 in such a way that the device 100 can only be inserted into the loading device 600 in one orientation. With the provision of such a coupling means, the user is prevented from inserting device 100 incorrectly, and thus the correct connections 300 of device 100 and contacts 610 are made each time device 100 is inserted into device 600. In addition , the tapered end portion 114 of the aerosol generating device 100 allows the user to more easily insert the device into cavity 602.
    [0073] Figure 7 shows a projection of an embodiment of an aerosol generating device 1000. The device comprises a first part 1010 of the housing and a second part 1020 of the housing. Both parts of the housing are substantially elongated tubes that have a decagonal cross section. When assembled, the first housing part and the second housing part are at a junction 1005. Junction 1005 can alternatively be placed in other positions, such as the positions indicated by lines 1007 or 1009, shown in Figure 7. With the provision of junction 1005 in positions 1007 or 1009, additional flexibility in relation to the size of the first and second housing parts 1010 and 1020 is provided.
    [0074] A 1030 button extends through the housing. The 1030 button is connected to the internal electronic components and allows a user to operate the device. The projections 1012, 1022 extend from each part of the housing adjacent to the button. These projections accentuate the position of the 1030 button, thereby allowing a user to operate the device without looking to see the position of the button. These projections 1012, 1022 also perform a coupling function when the device 1000 is coupled to a secondary unit. These projections 1012, 1022 also help to protect the button and prevent accidental activation of the device. These projections 1012, 1022 also contribute to the stability of the device by acting as barriers to the rolling of the device. As will now be apparent to an element versed in the technique, the inclusion of projections 1012 and 1022 is optional, since button 106 can provide equivalent functionality, as discussed in relation to Figures 1, 2, 3 (a) and 3 (b) above.
    [0075] An end end of the first casing part 1010 is tapered 1011. An end end of the second casing part 1020 is tapered 1021. The casing parts are made of injection molded polycarbonate (PC) which has a wall thickness of about 0.75 mm. The injection molds were produced with injection points at one end of the mold and flow lines of the injected polymer that extend along the longitudinal axis of each part of the casing. The total length of the device is about 94 mm.
    [0076] The external cross section of each part of the enclosure is decagonal. The faces of Decagon 1100 are slightly curved so that the cross section is a convex decagon. This is illustrated schematically in Figure 8 where the dotted lines represent a perfect decagon, and the solid lines represent a convex decagon. It should be noted that the curvature shown in Figure 8 has been greatly exaggerated for illustrative purposes.
    [0077] When the device 1000 is mounted and the first part 1010 of the enclosure adjoins the second part 1020 of the enclosure at junction 1005, the slightly curved decagonal faces 1100 produce an optical effect that does not accentuate any mismatch or misalignment in the two parts of the enclosure.
    [0078] The first casing part 1010 defines a substrate receiving cavity as described above with respect to the embodiment of Figure 1. That casing part 1010 can be slidably separated from the second casing part 1020 by sliding in a longitudinal direction . The first part 1010 of the housing can be removed from the device 1000 completely.
    [0079] An inner surface 1200 of the first part 1010 of the casing may have a decagonal cross section or, alternatively, it may be substantially cylindrical in shape. This inner surface 1200 engages with an inner part 1300 of the device body which is substantially cylindrical in shape. The first part 1010 of the housing is retained in device 1000 by means of compressors 1400 (see the regions outlined by circles in Figure 9). Compressors 1400 comprise a combination of protrusions 1410 located on an internal surface of the housing part with protruding protrusions 1310 or 1320 located on an external surface of an internal body. The inner surface 1200 of the first part 1010 of the enclosure has four pairs of longitudinally spaced protrusions 1410 that are spaced circumferentially within the inner surface 1200. These pairs of protrusions 1410 mate with the protruding protrusions 1310, 1320 protruding from the inner body 1300 When the first part of the casing 1010 abuts the second part 1020, the protruding pairs 1410 mate with a first set of protruding protrusions 1310. The first part 1010 of the casing is thus retained against the second part 1020 of the casing.
    [0080] With the application of a force in a longitudinal direction, compressors 1400 are decoupled when the protrusions 1410 in the first part 1010 of the enclosure decouple with the first set of protruding protrusions 1310 and the first part 1010 of the enclosure can slide freely in one longitudinal axis. In order to retain the first part 1010 of the casing in a second position, spaced longitudinally from the first position, the protrusions 1410 can couple with the second protruding protrusions 1320 located on the inner body 1300 and the compressors 1400 are re-coupled with the combination of protrusions 1410 and 1320. The second protruding protrusions 1320 are spaced longitudinally from the first protruding protrusions 1310. Protruding protrusions 1310, 1320 can be projected by cantilever springs.
    [0081] As discussed above, it may be advantageous for an aerosol generating device to comprise at least one tapered end. Figure 11 is a schematic illustration of an end of an aerosol generating device 2005 that has an example connection 2000 located on an end face 2010. The connection 2000 on the aerosol generating device 2005 is attachable to a contact 2030 located in an end face 2040 of a device receiving cavity 2050 from a loading device 2060. An inner wall 2045 of the device receiving cavity 2050 is tapered to bring the tapered surface 2015 closer to the aerosol generating device 2005. Since the aerosol generating device is inserted into cavity 2050, the tapered surfaces 2015, 2045 collide and guide connection 2000 and contact 2030 in alignment. It will now be apparent to an expert in the art that connection 2000 and contact 2030 may comprise one of connections 300 and one of contacts 608 discussed with respect to Figure 3 (b) above, and that such connections and contacts may facilitate the transfer of electrical or data charge between the aerosol generating device and the charging device discussed here.
    [0082] Other details of the construction and use of this modality are the same as those described above with respect to the modality of Figure 1.
    [0083] Naturally, it should be understood that the specification should not be restricted to the details of the above modalities which are described by way of example only.
