    [0001] The present invention relates to a smoking article comprising an aerosol-forming substrate for generating an inhalable aerosol when heated by an internal heating element of an aerosol generating device. The specification also refers to a method for using such an article for smoking.
    [0002] Several smoking articles in which the tobacco is heated rather than burned have been proposed in the art. An objective of such "heated" smoking articles is to reduce the known harmful smoke constituents of the type produced by combustion and pyrolytic degradation of tobacco in conventional cigarettes.
    [0003] Typically in such heated smoking articles, an aerosol is generated by transferring heat from a heat source to a physically separate aerosol-forming substrate or material, which can be located inside, around or downstream of the heat source. During smoking, volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and dragged into the air, swallowed through the smoking article. As the released compounds cool, they condense to form an aerosol that is inhaled by the user.
    [0004] Various prior art documents describe aerosol-generating devices for consuming or smoking heated smoking articles. Such devices include, for example, electrically heated aerosol generating devices, in which an aerosol is generated by transferring heat from one or more electrical heating elements of the aerosol generating device to the aerosol forming substrate of a smoking article. heated. An advantage of such electrical smoking systems is that they significantly reduce side smoke, while allowing a user to selectively suspend and resume smoking.
    [0005] An example of an electrically heated cigarette used in an electrical smoking system is described in the document in U.S. 2005/01722976 A1. In one embodiment, the electrically heated cigarette comprises a tobacco rod and a filter tip joined by tip paper. The tobacco rod includes a tobacco rod folded in a tubular shape over a free flow filter at one end and a tobacco rod at the other end. An empty space is between the free flow filter and the tobacco chunk. The empty space is an unfilled portion of the tobacco rod and is in fluid communication with the filter tip through the free flow filter. The electrically heated cigarette is built to be inserted in and a cigarette receiver from a reusable lighter from an electrical system for smoking. The lighter includes a power supply that provides power for a heater apparatus that includes a plurality of electrically resistant heating elements, which are arranged to slide the cigarette in, so that the heating elements are positioned along the cigarette.
    [0006] As described above, the electrically heated cigarette described in U.S. 2005/01722976 A1 is for use in an electrical smoking system comprising a plurality of external heating elements. As well as electrical smoking systems comprising aerosol generating devices with external heating elements, electrical smoking systems comprising aerosol generating devices with internal heating elements are also known. In use, the internal heating elements of the aerosol generating devices of such electrical smoking systems are inserted into the aerosol-forming substrate of a heated smoking article, so that the internal heating elements are in direct contact with the heating-forming substrate. aerosol.
    [0007] Direct contact between an internal heating element of an aerosol generating device, and the aerosol-forming substrate of a heated smoking article can provide an effective means of heating the aerosol-forming substrate to form an inhalable aerosol. In such a configuration, the heat from the internal heating element can be transported almost instantly to at least a portion of the aerosol-forming substrate, when the internal heating element is actuated, and this can facilitate the rapid generation of an aerosol. In addition, the total heating energy required to generate an aerosol may be less than would be the case in a smoking system that comprises an external heating element in which the aerosol-forming substrate does not directly contact the external heating element, and the Initial heating of the aerosol-forming substrate occurs by convection or radiation. Where an internal heating element of an aerosol generating device is in direct contact with an aerosol-forming substrate, initial heating of portions of the aerosol-forming substrate which is in direct contact with the internal heating element will be carried out by conduction.
    [0008] However, as well as the potential advantage described above, there are also potential advantages associated with the use of electrical smoking systems that comprise aerosol generating devices with internal heating elements.
    [0009] When inserting a heated smoking article into an aerosol-generating device comprising an internal heating element, a user may be required to apply significant force in order to overcome the resistance of the aerosol-forming substrate of the smoking article heated to insert the internal heating element of the aerosol generating device. This can damage one or both the heated smoking article and the internal heating element of the aerosol generating device.
    [00010] Furthermore, the application of significant force during the insertion of the internal heating element of the aerosol generating device in the aerosol-forming substrate of the heated smoking article can displace the aerosol-forming substrate within the smoking article. heated. This can result in the internal heating element not being fully inserted into the aerosol-forming substrate, which can lead to ineffective and irregular heating of the aerosol-forming substrate of the heated smoking article.
    [00011] For example, inserting an electrically heated cigarette, as described in US 2005/01722976 A1, into an aerosol generating device with an internal heating element will result in displacement of the tobacco chip towards the flow filter free space in the empty space between the free flow filter and the tobacco lump.
    [00012] WO2008 / 015441 publishes a device for delivering volatile materials. The device includes a heat transfer device, such as a thermal tube. In some embodiments, the heat transfer device must penetrate the source of a volatile material such as tobacco.
    [00013] EP 2 395 520 A1 describes a smokeless smoking tool comprising a thin heater that has a sharp end that is inserted directly into a commercially available cigarette or cigar to directly heat the tobacco leaves of the cigarette or cigar. The document in EP 2 395 520 A1 discloses that to allow a smoker to gently insert the heater into a standard filter cigarette that has a diameter of 8 mm, the heater diameter is required to be 2.3 mm or smaller and that attempts to insert heaters that have a diameter greater than 2.3 mm in a standard filter cigarette that has a diameter of 8 mm result in deformation of the filter cigarette contour or tearing of the filter cigarette paper.
    [00014] However, although it reduces the diameter of an internal heating element, as described in the document in EP 2 395 520 A1, and facilitates the insertion of the internal heating element in the aerosol-forming substrate of a heated smoking article, there are also potential advantages associated with the use of electrical smoking systems that comprise aerosol generating devices with thin internal heating elements.
    [00015] Reducing the diameter of the internal heating element, in relation to the diameter of the aerosol-forming substrate of the heated smoking article, adversely affects the heat dissipation through the aerosol-forming substrate, which is critical for the generation of a satisfactory aerosol .
    [00016] The present specification refers to a smoking article and a method for using a smoking article. In particular, the present specification relates to a smoking article which comprises an aerosol-forming substrate for generating an inhalable aerosol when heated by an internal heating element of an aerosol generating device. The specification also refers to a method for using such an article for smoking with an aerosol generating device that comprises an internal heating element.

    [00018] According to another aspect, there is provided a method for using a smoking article, according to the first aspect, with an aerosol generating device, in which the method comprising the steps of: inserting a heating element of an aerosol generating device on the aerosol-forming substrate of the smoking article, wherein the heating element has a diameter between approximately 40 percent and approximately 70 percent of the diameter of the aerosol-forming substrate; raising the temperature of the heating element of the aerosol generating device to heat the aerosol-forming substrate of the smoking article to generate an aerosol; and removing the heating element from the aerosol generating device from the aerosol-forming substrate of the smoking article.
    [00019] In another aspect, an aerosol generating system has been provided which comprises: an aerosol generating device comprising a heating element; and a smoking article for use with the aerosol generating device, wherein the smoking article comprises: an aerosol forming substrate located at an extreme upstream end of the smoking article, wherein the aerosol forming substrate is penetrable by the element heating the aerosol generating device; and a support element located immediately downstream of the aerosol-forming substrate, where the support element is adjacent to the aerosol-forming substrate, where the heating element of the aerosol-generating device has a diameter between approximately 40 percent and approximately 70 percent of the aerosol-forming substrate diameter. The aerosol forming substrate is configured to be penetrable by the heating element without substantial deformation of the smoking article.
    [00020] In accordance with an additional aspect, there is provided a method for producing a smoking article for use in an aerosol generating device, wherein the method comprises: providing an aerosol-forming substrate; providing a support element immediately downstream of the aerosol-forming substrate; and wrapping the aerosol-forming substrate and the supporting element in an outer wrap to form a smoking article, so that the aerosol-forming substrate is located at an extreme upstream end of the smoking article and the supporting element is contiguous aerosol-forming substrate. The aerosol forming substrate is configured to be penetrable by a heating element of an aerosol generating device having a diameter between approximately 40 percent and approximately 70 percent of the diameter of the aerosol forming substrate without substantial deformation of the smoking article.
    [00021] As used herein, the term "aerosol-forming substrate" is used to describe a substrate that is capable of releasing volatile compounds, which can form an aerosol, upon heating. Aerosols generated from the aerosol-forming substrate of smoking articles, described in this document, may be visible or invisible and may include vapors (for example, fine particles of substances, which are in a gaseous state, which are generally liquid or solid at room temperature) as well as liquid drops and condensed vapors gases.
    [00022] As used in this document, the terms "upstream", "downstream", "proximal" and "distal" are used to describe the relative positions of the elements or portions of the elements, aerosol generating devices and the generating system aerosols of smoking articles according to the invention.
    [00023] Smoking articles, as described in this document, comprise a proximal end through which, in use, an aerosol leaves the aerosol generating article. The proximal end can also be referred to as the mouth end. In use, a user brings the mouth or proximal end of the smoking article in order to inhale an aerosol generated by the smoking article. The smoking article comprises a distal end opposite the mouth or proximal end. The mouth or proximal end of the smoking article can also be referred to as the downstream end and the distal end of the smoking article can also be referred to as the upstream end. The components, or portions of components, of the smoking article can be described as being upstream or downstream of another based on their positions, relative between the proximal or downstream end and the distal or upstream end of the smoking article .
    [00024] As used herein, the term "extreme upstream end" is used to describe the outermost or furthest upstream portion of the smoking article.
    [00025] As used in this document, the term "diameter" is used to refer to the maximum transverse dimension of the elements, or portions of the elements, of aerosol generating devices and the aerosol generating system of smoking articles, in accordance with with the invention. For the avoidance of doubt, as used in this document, the term "diameter" can refer to the "width" of the elements or portions of the elements, of aerosol generating devices and the aerosol generating system of smoking articles, according to non-circular cross-section invention.
    [00026] As used herein, the term "longitudinal" is used to describe the direction between the proximal or downstream end and the distal upstream or opposite end of smoking articles, aerosol generating devices and the aerosol generating system , according to the invention and the term "transverse" is used to describe the direction perpendicular to the longitudinal direction.
    [00027] For the avoidance of doubt, in the following description the term "heating element" is used to mean one or more heating elements.
    [00028] The inclusion of a support element immediately downstream of and in contiguity with the aerosol-forming substrate of the smoking article provides several advantages.
    [00029] In preferred embodiments, the support element is configured to resist movement downstream of the aerosol forming substrate during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [00030] The insertion force experienced by the smoking article, as it is inserted into the aerosol generating device by a user, can be divided into three parts: friction force, penetration force and crushing force.
    [00031] As the smoking article is initially inserted into the aerosol generating device and anterior to the heating element of the aerosol generating device which is inserted into the aerosol forming substrate of the smoking article, the insertion force is dominated by the force required to overcome friction due to interference between the outer surface of the smoking article and the inner surface of the aerosol generating device. As used herein, the term "friction force" is used to describe the maximum insertion force before the heating element of the aerosol generating device is inserted into the aerosol-forming substrate of the smoking article.
    [00032] As the smoking article is then inserted into the aerosol generating device, and before the smoking article reaches a maximum insertion position, the insertion force is dominated by the force required to overcome the resistance of the article's aerosol-forming substrate to smoke when inserting the internal heating element of the aerosol generating device.
    [00033] As used herein, the term "penetrating force" is used to describe the maximum insertion force during insertion of the heating element into the aerosol-forming substrate of the smoking article, and before the smoking article reaches a maximum insertion position.
    [00034] Once the smoking article reaches a maximum insertion point, the insertion force is dominated by the force required to deform the smoking article. In the maximum insertion position, the extreme upstream end of the smoking article may come into contact with a surface, for example, a lower or rear surface, of the aerosol generating device, which prevents the smoking article from being inserted into the device later. aerosol generator.
    [00035] As used in this document, the term "grinding force" is used to describe the maximum insertion force after the smoking article reaches a maximum insertion point.
    [00036] The support element of the smoking article resists the penetrating force experienced by the smoking article during the insertion of the internal heating element of the aerosol generating device in the aerosol forming substrate.
    [00037] The insertion force required to insert a heating element into an aerosol-forming substrate where the heating element has a diameter between approximately 40 percent and approximately 70 percent of the diameter of the aerosol-forming substrate is greater than the insertion force required to insert a heating element into an aerosol-forming substrate where the heating element has a smaller diameter in relation to the diameter of the aerosol-forming substrate.
    [00038] In one embodiment, the support element is configured to withstand a penetrating force of at least 2.5 N during insertion of the heating element of the aerosol generating device into the aerosol-forming substrate. The support element can be configured to withstand a penetration force of between approximately 2.5 N and approximately 10 N, during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [00039] In another embodiment, the support element is configured to withstand a penetrating force of at least 4 N during the insertion of the heating element of the aerosol generating device in the aerosol forming substrate. The support element can be configured to withstand a penetrating force of between approximately 4 N and approximately 10 N during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [00040] The support element of the smoking article resists movement downstream of the aerosol forming substrate within the smoking article during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [00041] This can help to ensure that the heating element of the aerosol generating device is fully inserted into the aerosol-forming substrate and thus preventing ineffective and irregular heating of the aerosol-forming substrate of the heated smoking article.
    [00042] In one embodiment, the supporting element has a breaking force of at least 40 N, for example, a breaking force of at least 45 N or at least 50 N. The breaking force is measured by conditioning the support element for at least 24 hours at 22 ± 2 degrees Celsius and 50 ± 5% relative humidity and then compressing the support element to break at a constant compression rate using an Instron® 5565 series or an equivalent tensile testing machine with a 100 N charged cell. The test starts when a 0.5 MPa preload is measured and ends when the load has dropped to 60% of the maximum load. The breaking force is the maximum force recorded during the test.
    [00043] The support element can be formed from any suitable material or combination of materials. For example, the support element can be formed from one or more materials selected from the group consisting of: cellulose acetate; cardboard; wrinkled paper, such as heat-resistant wrinkled paper or wrinkled parchment paper; and polymeric materials, such as low density polyethylene (LDPE). In one embodiment, the support element can be formed from cellulose acetate.

In certain embodiments, the support element can have an internal diameter of approximately 3 millimeters and approximately 4 millimeters. In one embodiment, the support element can have an internal diameter of approximately 3.3 millimeters. In other embodiments, the support element can have an internal diameter of between approximately 6.5 mm and approximately 7.5 mm. In one embodiment, the support element may have an internal diameter of approximately 6.9 mm.
    [00050] The support elements comprising a hollow tubular element allow volatile compounds released from the aerosol-forming substrate by heat transfer from the heating element of the aerosol generating device to pass downstream through the hollow tubular element while resisting also to a movement downstream of the aerosol forming substrate during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [00051] Where the support element comprises a hollow tubular element, the aerosol velocity that passes downstream through the support element is dependent on the inner diameter of the hollow tubular element.
    [00052] As further described below, the smoking article may comprise a transfer element comprising an aerosol cooling element or heat exchanger located between the support element and a nozzle located at the extreme downstream end of the smoking article. The speed of the aerosol passing downstream through the support element can affect the effectiveness of the heat exchange between the aerosol and the cooling element by aerosol or heat exchanger.
    [00053] Where the support element comprises a hollow tubular element, the inner diameter of the hollow tubular element can be between approximately 35 percent and approximately 98 percent of the outer diameter of the hollow tubular element. In certain embodiments, the inner diameter of the hollow tubular element can be between approximately 35 percent and approximately 55 percent of the outer diameter of the hollow tubular element. In other embodiments, the inner diameter of the hollow tubular element can be between approximately 90 percent and approximately 98 percent of the outer diameter of the hollow tubular element.
    [00054] The aerosol forming substrate is configured to be penetrable by a heating element of an aerosol generating device that has a diameter between approximately 40 percent and approximately 70 percent of the diameter of the aerosol forming substrate.
    [00055] The aerosol forming substrate is configured to be penetrable by a heating element of an aerosol generating device that has a diameter between approximately 40 percent and approximately 70 percent of the diameter of the aerosol forming substrate without substantial deformation of the article. to smoke.
    [00056] As used herein, the term "substantial deformation" is used to describe one or more of the curvature of the smoking article by more than approximately 7 degrees with respect to the longitudinal axis of the smoking article and tearing or tearing of a external wrap of the article for smoking.
    [00057] In preferred embodiments, the support element is resistant to the maximum temperature to which it is exposed at an interface when using the article to smoke in an aerosol generating device. As used herein, the term "interface" is used to describe a plane or point of contact that adjoins an end of the support element.
    [00058] In the exemplary embodiment illustrated in Figure 1, a first interface 82 is the plane between the upstream end of support element 30 and the downstream end of aerosol forming substrate 20, and a second interface 84 is the plane between the the downstream end of the support element 30 and the upstream end of the transfer section 40.
    [00059] In the exemplary embodiment illustrated in Figure 5, a first interface 82 is the plane between the upstream end of support element 30 and the downstream end of aerosol-forming substrate 20, and a second interface is the plane between the end downstream of support member 30 and the upstream end of the smoking article residue 200.
    [00060] In certain embodiments, the support element is resistant to exposure to a temperature of at least approximately 100 ° C for a period of at least approximately 5 minutes. In preferred embodiments, the support element is resistant to exposure to a temperature of at least approximately 120 ° C, for a period of at least approximately 5 minutes. In particularly preferably preferred embodiments, the support element is resistant to exposure to a temperature of at least approximately 150 ° C for a period of at least approximately 6 minutes.

    [000106] Figure 6 is a schematic view of the support element of the smoking article according to the embodiment illustrated in Figure 5.
    [000107] Figure 1 illustrates an article for smoking 10 according to a modality. The smoking article 10 comprises four elements arranged in coaxial alignment: an aerosol forming substrate 20, a support element 30, a transfer section 40, and a nozzle 50. These four elements are arranged sequentially and are circumscribed by an outer wrap 60 to form the smoking article 10. The smoking article 10 has a mouth end 70, in which a user inserts into his mouth during use, and a distal end 80 located at the opposite end of the article for smoke 10 to the mouth end 70.
    [000108] In use, air is sucked through the smoking article by a user from the distal end 80 to the mouth end 70. The distal end 80 of the smoking article can thus also be described as the upstream end of the smoking article. smoking article 10 and the mouth end 70 of the smoking article 10 can also be described as the downstream end of the smoking article 10. Elements of the smoking article 10 located between the mouth end 70 and the distal end 80 can be described as being upstream of the mouth end 70 or, alternatively, downstream of the distal end 80.
    [000109] The aerosol forming substrate 20 is located at the extreme distal end or upstream of the smoking article 10. In the embodiment illustrated in Figure 1, the aerosol forming substrate 20 comprises a blade collected from wrinkled material of homogenized tobacco circumscribed by a wrap. The wrinkled blade of homogenized tobacco material comprises comprising glycerin as an aerosol former.
    [000110] The support element 30 is located immediately downstream of the aerosol-forming substrate 20 and adjoins the aerosol-forming substrate 20 along a first interface 82, which is the plane between the upstream end of the support element 30 and the downstream end of aerosol-forming substrate 20.
    [000111] In the embodiment shown in Figure 1, the support element is a hollow cellulose acetate tube. The support element 30 locates the aerosol forming substrate 20 at the opposite distal end 80 of the smoking article 10 so that it can be in contact with an internal heating element of an aerosol generating device. As further described below, the support element 30 acts to prevent the aerosol forming substrate 20 from being forced downstream into the smoking article 10 towards the transfer element 40 when an internal heating element of an aerosol generating device is inserted into the aerosol forming substrate 20. The support element 30 also acts as a spacer to space the transfer element 40 of the smoking article from the aerosol forming substrate 20.
    [000112] Transfer element 40 is located immediately downstream of support element 30 and adjoins support element 30 along a second interface 84, which is the plane between the downstream end of support element 30 and the upstream end of the transfer element 40. In use, volatile substances released from the aerosol-forming substrate 20 pass along the transfer section 40 towards the mouth end 70 of the smoking article 10. Volatile substances can cool within the section transfer 40 to form an aerosol which is inhaled by the user. In the embodiment illustrated in Figure 1, the transfer element 40 is an aerosol cooling element comprising a corrugated and collected polylactic acid sheet enclosed by a wrap 90. The corrugated and collected polylactic acid sheet defines a plurality of longitudinal channels that extend along the length of the aerosol cooling element 40.
    [000113] The nozzle 50 is located immediately downstream of the transfer section 40 and is adjacent to the transfer section 40. In the embodiment illustrated in Figure 1, the nozzle 50 comprises a conventional cellulose acetate tow filter of low filtration efficiency .
    [000114] To assemble the smoking article 10, the four elements described above are aligned and tightly wrapped inside the outer wrapper 60. In the embodiment illustrated in Figure 1, the outer wrapper is a conventional cigarette paper. As shown in Figure 1, a row of perforations is provided in a region of the outer casing 60 that circumscribes the support element 30 of the smoking article 10.
    [000115] The smoking article shown in Figure 1 is designed to engage with an aerosol generating device that comprises an internal heating element in order to be smoked or consumed by a user. In use, the internal heating element of the aerosol generating device heats the aerosol-forming substrate 20 of the smoking article 10 to a temperature sufficient to form an aerosol, which is sucked down through the smoking article 10 and inhaled by the user.
    [000116] Figure 2 illustrates a portion of an aerosol generating system 100 comprising an aerosol generating device 110 and a smoking article 10 according to the embodiment described above and illustrated in Figure 1.
    [000117] The aerosol generating device comprises an internal heating element 120. As shown in Figure 2, the heating element 120 is mounted inside a smoking article receiving chamber of the aerosol generating device 100. In use, the user inserts the smoking article 10 into the smoking article receiving chamber of the aerosol generating device 110 so that the internal heating element 120 is inserted into the aerosol forming substrate 20 of the smoking article 10 as shown in Figure 2. In As shown in Figure 2, the internal heating element 120 of the aerosol generating device 110 is a heating paddle.
    [000118] The aerosol generating device 110 comprises a power supply and electronics (not shown) that allow the internal heating element 120 to be activated. Such actuation may be manually operated or may occur automatically in response to a user sucking a smoking article 10 inserted into the smoking article receiving chamber of the aerosol generating device 110. A plurality of openings are provided in the aerosol generating device for allowing air to flow into the smoking article 10; the air flow direction is illustrated by arrows in Figure 2.
    [000119] Figure 3 illustrates an embodiment of an aerosol generating device 110 comprising an internal heating element 120 for use with the smoking article 10 according to the embodiment described above and illustrated in Figure 1. The aerosol generating device. 110 comprises a power supply and electronics (not shown) that allow the internal heating element 120 to be actuated. Such actuation can be manually operated or can occur automatically in response to a user who sucks a smoking article inserted into the aerosol generating device 110. In the embodiment shown in Figure 3, the internal heating element 120 is a pin heater.
    [000120] In use, the user inserts the smoking article 10 into a first open end 130 of the aerosol generating device 110 so that the internal heating element 120 is inserted into the aerosol forming substrate 20 of the smoking article 10.
    [000121] As discussed above, the insertion force experienced by the smoking article 10 as it is inserted into the aerosol generating device 110 by the user is divided into three parts. First, as the smoking article 10 is initially inserted into the aerosol generating device 110, the smoking article experiences a frictional force due to the interference between the outer surface of the smoking article and the inner surface of the aerosol generating device. Second, as the smoking article 10 is further inserted into the aerosol generating device 110, the smoking article experiences a penetrating force due to the insertion of the internal heating element of the aerosol generating device 110 into the aerosol forming substrate. 20 of the smoking article 10. Finally, as the smoking article 10 is further inserted into the aerosol generating device 110, the smoking article experiences a grinding force due to the distal end 80 of the smoking article in contact with one another. second closed end 140 of the aerosol generating device 110 opposite the first open end thereof.
    [000122] The support element 40 of the smoking article 10 resists the penetrating force experienced by the smoking article 10 during insertion of the internal heating element 120 of the aerosol generating device 110 into the aerosol forming substrate 20. The support element 40 of the smoking article 10 thus resists movement downstream of the aerosol forming substrate within the smoking article 10 during insertion of the heating element of the aerosol generating device into the aerosol forming substrate.
    [000123] Once the internal heating element 120 is inserted into the actuated aerosol-forming substrate 10 of the smoking article 10 and actuated, the aerosol-forming substrate 20 of the smoking article 10 is heated to a temperature of about 375 degrees Celsius by the internal heating element 120 of the aerosol generating device 110. At this temperature, volatile compounds are developed from the aerosol-forming substrate 20 of the smoking article 10. As a user sucks at the mouth end 70 of the smoking article 10, the volatile compounds developed from the aerosol-forming substrate 20 are sucked downstream through the smoking article 10 and condensed to form an aerosol which is sucked through the mouthpiece 50 of the smoking article 10 into the user's mouth.
    [000124] As the aerosol passes downstream through the transfer element 40, the temperature of the aerosol is reduced due to the transfer of thermal energy from the aerosol to the aerosol cooling element. When the aerosol enters the aerosol cooling element, its temperature is about 60 degrees Celsius. Due to the cooling inside the aerosol cooling element, the temperature of the aerosol as it leaves the aerosol cooling element is about 40 degrees Celsius. EXAMPLE
    [000125] The insertion force required to insert smoking articles according to the modality illustrated in Figure 1 to an aerosol generating device according to the modality shown in Figure 3 was measured and used to evaluate the frictional force, penetration and crushing force experienced by smoking articles. MATERIALS & METHODS
    [000126] Materials: Ten smoking articles according to the modality illustrated in Figure 1 with the dimensions given in Table 1 and an aerosol generating device according to the modality illustrated in Figure 3 with the dimensions identified A, B, C, D, E and F in Figure 3 given in Table 2 were used in the measurements.
    TABLE 1
    TABLE 2
    [000127] Methods: The smoking articles were inserted into the aerosol generating device through the first open end of the same at a rate of 800 mm / min using an INSTRON 5565 tensile testing machine with adaptation retention equipment. The insertion force as a function of the insertion distance of the first open end of the aerosol generating device was measured and recorded.
    [000128] Results: Figure 4 shows a graph of the insertion force measured as a function of the insertion distance for each of the ten smoking articles.
    [000129] At an insertion distance of 5 mm, the smoking articles reach a first constriction in the internal diameter of the aerosol generating device and the insertion force begins to increase due to the friction between the outer surface of the smoking articles and the surface interior of the cigarette aerosol generating device as shown in Figure 4. The friction resulting from the first constriction dominates the insertion force up to an insertion distance of about 18 mm. At that insertion distance, the insertion force decreases slightly before the smoking articles reach a second constriction in the internal diameter of the aerosol generating device at an insertion distance of 18 mm and the insertion force begins to increase due to the friction between the outer surface of the smoking articles and the inner surface of the cigarette aerosol generating device.
    [000130] At an insertion distance of 20 mm, the pin heater of the aerosol generating device begins to penetrate the smoking article and the insertion force also increases due to the resistance of the aerosol-forming substrate of the smoking article to the insertion of the pin heater of the aerosol generating device. The resistance of the aerosol-forming substrate to the insertion of the pin heater dominates the insertion force up to an insertion distance of about 31.5 mm. As shown in Figure 4, at that insertion distance the insertion force increases rapidly due to the distal end or upstream of the smoking articles in contact with the second closed end of the aerosol generating device. After the smoking articles begin to deform and the insertion force both decreases slightly and continues to increase during the deformation of the smoking articles.
    [000131] For each measured smoking article, the frictional force was assessed as the maximum insertion force measured up to an insertion distance of 20 mm. The average frictional force for the ten smoking articles measured is given in Table 3.
    [000132] For each measured smoking article, the penetration force was assessed as the maximum insertion force measured up to an insertion distance of 31.5 mm. The average penetration force for the ten smoking articles measured is given in Table 3.
    TABLE 3
    [000133] Figure 5 illustrates the aerosol forming substrate 20 and support element 30 of a smoking article 200 according to another embodiment. The aerosol forming substrate 20 is located at the extreme distal end or upstream of the smoking article 200. In the embodiment illustrated in Figure 5, the aerosol forming substrate 20 is 18 mm long and 7.2 mm in diameter and comprises a blade collected from wrinkled material of homogenized tobacco circumscribed by a wrap. The wrinkled blade of homogenized tobacco material comprises comprising glycerin as an aerosol former.
    [000134] The support element 30 is located immediately downstream of the aerosol-forming substrate 20 and adjoins the aerosol-forming substrate 20 along a first interface 82, which is the plane between the upstream end of the support element 30 and the downstream end of the aerosol forming substrate 20. In the embodiment shown in Figure 5, the support element is a hollow cellulose acetate tube and is 8 millimeters long. As shown in Figure 6, the support element has an internal diameter of 3.3 mm and an external diameter of 7.2 mm.
    [000135] The support element 30 adjoins the remainder of the smoking article 200 along a second interface 84, which is the plane between the downstream end of the supporting element 30 and the upstream end of the remainder of the smoking article 200.
    [000136] Although the support elements of the smoking article according to the modalities described above and illustrated in Figures 1 and 6 are formed from cellulose acetate, it will be appreciated that this is not essential and that smoking articles according to other modalities they may comprise support elements formed from other materials or an appropriate combination of materials.
    [000137] Similarly, although the smoking article according to the mode described above and illustrated in Figure 1 comprises a transfer element comprising an aerosol cooling element comprising a wrinkled and collected polylactic acid blade, it will be appreciated that this is not essential and that smoking articles according to other modalities may comprise other transfer elements or may not comprise a transfer element.
    [000138] Furthermore, although the smoking article according to the modality described above and illustrated in Figure 1 has four elements circumscribed by an external wrap, it will be appreciated that this is not essential and that smoking articles according to other modalities can comprise additional elements or fewer elements.
    [000139] It will also be appreciated that although the four elements of the smoking article according to the modality described above and illustrated in Figure 1 are circumscribed by an external wrapping of conventional cigarette paper, this is not essential and that the elements of articles for smoking according to other modalities can be circumscribed by other external wraps.
    [000140] It will be further appreciated that the dimensions provided for the elements of the smoking articles according to the modalities described above and illustrated in Figures 1 and 5 and parts of the aerosol generating device according to the embodiment described above and illustrated in Figure 3 they are merely exemplary, and what suitable alternative dimensions can be chosen.
    [000141] The exemplary modalities described above are not limiting. Other modalities consistent with the exemplary modalities described above will be evident to those skilled in the art.
