Description

Technical Field

[0001] The present invention relates to a consumable set for an aerosol generating device. Such a consumable set particularly comprises a tobacco article configured to operate with an aerosol generating device.

[0002] Particularly, the tobacco article comprises a tobacco substrate that can form an aerosol when heated by an aerosol generating device. Thus, such types of aerosol generating devices, also known as non-combustion heating devices, are adapted to heat rather than burn to generate an aerosol for inhalation.

Background Art

[0003] The popularity and use of risk reduction devices or risk modification devices (also known as vaporizers) have been rapidly increasing in recent years as an aid to assist habitual smokers who wish to quit smoking conventional tobacco products such as cigarettes, cigars, cigarillos, and roll-your-own tobacco. In contrast to burning tobacco in conventional tobacco products, various devices and systems for heating or warming a vaporizable substance are available.

[0004] Commonly available risk reduction or risk modification devices are substrate-heated aerosol generators or non-combustion-heated devices. These types of devices generate aerosols or vapors by heating an aerosol substrate, usually contained in separate consumables. Such aerosol substrates typically include moist tobacco leaves or other suitable vaporizable materials at temperatures ranging from 150°C to 350°C. By heating the aerosol substrate rather than burning or incinerating it, an aerosol is released that contains the components desired by the user but is free from toxic and carcinogenic by-products resulting from combustion and incineration. Furthermore, because aerosols generated by heating tobacco or other vaporizable materials typically do not contain the burnt or bitter taste resulting from combustion and incineration, which can be unpleasant to the user, the substrate does not require sugars and other additives typically added to such materials to make the smoke and / or vapor more palatable to the user's mouth.

[0005] Tobacco articles usable with such aerosol generating devices can take various forms. Some may be elongated sticks, or other suitable shapes such as flat plates. Generally, such tobacco articles are at least partially contained within a heating chamber of a device that includes one or more heaters for heating the tobacco articles.

[0006] Once at least partially received into the heating chamber, the tobacco article is configured to generate an aerosol that is delivered to the user via the mouthpiece. In some known devices, the mouthpiece is part of the device. However, in this case, it may need to be cleaned periodically. For example, for hygienic reasons, the outer surface of the mouthpiece may need to be cleaned each time before using the device, and at least occasionally, the inner surface of the mouthpiece may need to be cleaned to remove condensation that forms during vaping. In some other devices, the mouthpiece may be formed by the aerosol-generating article itself. Therefore, cleaning can be avoided, but its use may be difficult for the user, especially if the dimensions of the tobacco article are reduced. In addition, such a mouthpiece may become too hot to touch the user's lips, and special cooling measures may be required. [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] One of the objectives of the present invention is to propose a consumable set that provides a mouthpiece that does not require cleaning and can be easily used even with articles whose dimensions have decreased. [Means for solving the problem]

[0008] For this purpose, the present invention is a consumable set for an aerosol generating device, - A tobacco article comprising a base material portion and a cooling portion that extends along the article axis and is continuously arranged with respect to the base material portion along the article axis, - A mouthpiece comprising a recess configured to receive the cooling portion of a tobacco product, The cooling section relates to a consumable set, whose boundaries are defined by a wrapper extending around the item axis.

[0009] While possessing these characteristics, the mouthpiece becomes part of a consumable set, i.e., a set that can be purchased and replaced independently of the aerosol generating device. This set also includes one or more tobacco products, so that users can purchase it naturally when purchasing tobacco products according to their habits. Therefore, the mouthpiece is used with its or each tobacco product in the set, and can then be replaced with another mouthpiece when the user purchases another set. In other words, like tobacco products, the mouthpiece can also form a disposable consumable product that can be replaced after being used with one or more tobacco products.

[0010] According to different embodiments of the present invention, a mouthpiece can be associated with each tobacco article in a set. Therefore, when a tobacco article is used up, the mouthpiece is replaced along with the tobacco article. According to another embodiment, a single mouthpiece can be associated with several tobacco articles. In this case, the number of tobacco articles can be between 5 and 25, preferably between 10 and 20. According to this embodiment, when a tobacco article is used up, the mouthpiece can be used with another tobacco article until all tobacco articles in the consumable set are used up.

[0011] Advantageously, mouthpieces with consumable sets do not require cleaning, as they can be easily replaced by purchasing another consumable set. Furthermore, when tobacco products have reduced dimensions (e.g., flat), the mouthpieces in consumable sets are ergonomically designed and better fitted to the user's lips / mouth compared to some tobacco products that are suitable for use as mouthpieces themselves.

[0012] In addition, if a mouthpiece is lost, a new mouthpiece can be purchased along with the tobacco product. Furthermore, if the aerosol generating device is shared among multiple users, each user may have their own mouthpiece to improve hygiene.

[0013] According to some embodiments, the mouthpiece may be equipped with a flavoring substance related to the tobacco article in the consumable set. This flavoring substance can enhance the flavoring of the tobacco article in the consumable set. Therefore, if a user uses a consumable set with tobacco articles that have a different flavor, he / she can also replace the mouthpiece with one that better suits the new flavor. In other words, the flavoring substance of the mouthpiece can be selected to match the flavor of the tobacco article in the same consumable set.

[0014] According to some embodiments, the mouthpiece is made of at least partially biodegradable material. Therefore, the mouthpiece can be easily recycled after use.

[0015] In addition, the cooling portion of the tobacco article can be adapted to be received by the mouthpiece. For example, if the cooling portion is bounded by a wrapper, the outer surface of the wrapper can come into contact with the inner surface of the mouthpiece. Thus, leakage of the flow between the mouthpiece and the tobacco article can be avoided. In other words, the mouthpiece can ensure that it provides a seal. In some embodiments, the mouthpiece may be further provided with a sealing member, for example, designed to extend around the wrapper when the cooling portion is received by the mouthpiece.

[0016] Advantageously, once the cooling portion is received by the mouthpiece, the mouthpiece prevents the wrapper from folding inward.

[0017] In some embodiments, the wrapper is made of paper.

[0018] The paper can be the same as that used as tip paper in conventional tobacco products. In the modified example, the paper is different from one of the conventional tobacco products.

[0019] In some embodiments, the cooling portion is hollow overall.

[0020] The term "hollow overall" is understood to mean that the cooling portion is a void, and only the wrapper defines the volume boundary that constitutes the cooling portion. In this case, the wrapper can be provided as a single or multilayer sheet that can be associated with one or more support elements that extend at least partially along the sheet in some embodiments. Each of these support elements can at least partially overlap the wrapper to support its structure that forms the cooling portion.

[0021] The overall hollow cooling section can be particularly efficient when it is necessary to cool the aerosol generated by the substrate without causing a significant pressure drop. In addition, since the cooling section is received by the mouthpiece, the mouthpiece can prevent the wrapper from folding inward, even if it is supplied without support.

[0022] According to some embodiments, the base material portion has a flat plate shape, each having a suitably rectangular cross-section.

[0023] The shape of the base material is particularly advantageous in ensuring a rapid preheating phase for the tobacco article. Therefore, the article may be ready to generate vapor in just a few seconds (e.g., 5 seconds, or 15 seconds, or 20 seconds) after the heating is activated.

[0024] In some cases, the entire tobacco article can be defined as a flat plate. For example, the cooling portion can have approximately the same cross-sectional shape as the base material portion.

[0025] By virtue of at least one of the tobacco article or a part thereof being “flat plate-shaped”, it extends between two first parallel longitudinal planes and two second parallel longitudinal planes perpendicular to the first parallel longitudinal planes, and it is understood that the distance between the second parallel longitudinal planes is at least 3 times, preferably 5 times, more preferably 10 times greater than the distance between the first parallel longitudinal planes.

[0026] According to some embodiments, the mouthpiece further defines a flow channel that extends a recess.

[0027] The flow channel can thus be used to deliver an aerosol that is formed in the base portion of the tobacco article and cooled in the cooling portion of the article.

[0028] According to some embodiments, the recess and the flow channel form a through-hole that extends between two opposing surfaces of the mouthpiece in the mouthpiece.

[0029] In other words, the mouthpiece presents a through-hole suitable for inserting the cooling portion of the tobacco article at one end and delivering the aerosol at the other end.

[0030] According to some embodiments, the mouthpiece further forms a stop in the transition zone between the recess and the flow channel to prevent the tobacco article from entering the flow channel.

[0031] With these features, the tobacco article can be accurately positioned with respect to the mouthpiece, and advantageously with respect to the device. Thereby, the risk of leakage and heat loss can be further reduced. The stop can be formed by a protrusion or a shoulder. The shoulder can be formed in the transition zone between the base portion and the cooling portion. For example, the cross-sectional area of the cooling portion can be made at least slightly smaller than the cross-sectional area of the base portion, and thus a shoulder is formed in the transition zone.

[0032] According to some embodiments, the recess has a shape complementary to the shape of the cooling portion.

[0033] Therefore, the recess can be precisely fitted to the outer shape of the cooling section, minimizing the gap between the cooling section and the mouthpiece. This further reduces vapor leakage.

[0034] In some embodiments, tobacco articles from the same consumable set may have a specific cross-sectional shape in the corresponding cooling portion. In this case, the mouthpiece comprising the consumable set has a recess that fits into this specific cross-sectional shape of the cooling portion. In other words, in some embodiments, mouthpieces from different consumable sets cannot be interchanged.

[0035] According to some embodiments, the recess or cooling portion comprises at least one inner wall that forms one or more airflow channels when the cooling portion is received within the recess. In some embodiments, the airflow channels or each of them extend along the axis of the article.

[0036] The inner walls can be used to support the wrapper that defines the boundary of the cooling area. For example, if one or more inner walls are formed in the cooling area, these walls can extend between opposing walls of the cooling area, thus preventing the wrapper from folding inward while it is inserted into the mouthpiece. If one or more inner walls are formed in the cooling area, a gap can be provided between these walls and the inner surface of the wrapper that defines the boundary of the recess. This gap allows the wrapper of the tobacco article to be inserted so that the inner walls are received by the cooling area. In some cases, the tobacco article may be guided by the gap while it is inserted into the recess of the mouthpiece.

[0037] According to some embodiments, the mouthpiece is formed by injection molding.

[0038] This method can be advantageously used to form the mouthpiece, since the mouthpiece is already used to form at least some parts of the tobacco article and / or in the packaging. Therefore, the mouthpiece can be formed in an efficient and inexpensive way.

[0039] According to some embodiments, the mouthpiece is formed from an absorbent material.

[0040] This material, such as paper, can be used to absorb the vapor that forms inside the mouthpiece. This minimizes leakage of the vapor stream during or after a vaping session.

[0041] According to some embodiments, the mouthpiece is made of paper.

[0042] Paper is a good absorbent material that allows for minimizing flow leakage during or after a vaping session. Paper also does not conduct heat by nature; its thermal conductivity can be as low as approximately 0.05 W / (m·K). With these characteristics, the mouthpiece can remain relatively cool, even when the base material is heated and generating aerosols. Finally, paper is relatively inexpensive and easily recyclable.

[0043] The texture of the paper used to form the mouthpiece can be the same as that of conventional tobacco products, for example, it can be the same as one of the tip papers used as a wrapper in conventional tobacco products. This gives the user a more natural feel.

[0044] According to several embodiments, the consumable set comprises a plurality of tobacco articles and at least one mouthpiece adapted to receive the cooling portion of each tobacco article. The number of tobacco articles can be between 5 and 25, preferably between 10 and 20.

[0045] According to some embodiments, the consumable set forms a pack of tobacco articles. In other words, the consumable set is a pack of tobacco articles.

[0046] In this case, it may comprise a box adapted to accommodate, for example, multiple tobacco articles and at least one mouthpiece. The box may comprise a lid and an internal liner to retain the flavor of the tobacco articles and / or mouthpiece. Special compartments may be designed inside the box to accommodate, for example, one or more mouthpieces.

[0047] The present invention and its advantages are given as non-limiting embodiments and will be better understood by reading the following description, which is made with reference to the accompanying drawings. [Brief explanation of the drawing]

[0048] [Figure 1] This is a schematic diagram of an aerosol generating assembly comprising an aerosol generating device and a consumable set according to the present invention, the consumable set comprising a tobacco article and a mouthpiece. [Figure 2] Figure 1 is a perspective view of a tobacco product. [Figure 3] Figure 1 shows cross-sectional views of several embodiments of the tobacco article. [Figure 4] Figure 1 shows different schematic diagrams of the tobacco article and the mouthpiece that engages with / disengages from it. [Figure 5] Figure 1 is a schematic diagram of a tobacco product pack comprising multiple tobacco products and at least one mouthpiece. [Modes for carrying out the invention]

[0049] Before describing the present invention, it should be understood that the present invention is not limited to the structural details described below. It will be apparent to those skilled in the art who are interested in this disclosure that other embodiments are possible and that the present invention can be implemented or carried out in various ways.

[0050] As used herein, the terms “aerosol generating device” or “device” may include a vaping device that delivers an aerosol to a user, including an aerosol for vaping, using a heater element, which is described in more detail below. The device may be portable. “Portable” may mean a device intended for use when held by a user. The device may be adapted to generate a variable amount of aerosol (as opposed to a fixed amount of aerosol) by, for example, activating a heater element over a variable amount of time. The variable amount of aerosol may be controlled by a trigger. The trigger may be user-activated, such as a vaping button and / or an inhalation sensor. The inhalation sensor may be highly sensitive to inhalation intensity and duration, and may enable the provision of a variable amount of vapor (to mimic the smoking effect of conventional flammable smoking articles such as cigarettes, cigars, or pipes). The device may include a temperature control unit for driving the temperature of the heater and / or heated aerosol generating material (aerosol precursor) to a specific target temperature, and then maintaining the temperature at the target temperature to enable efficient aerosol generation.

[0051] As used herein, the term "aerosol" may include suspended matter of a vaporizable material as one or more solid particles, droplets, or gases. The suspended matter may be in a gas, including air. In general, aerosols as used herein may refer to / include vapors. Aerosols may include one or more components of a vaporizable material.

[0052] As used herein, the terms “vaporizable material” or “precursor” may refer to a smokeable material and an aerosol-forming agent, which may, for example, comprise nicotine or tobacco. Tobacco may take the form of various materials such as shredded tobacco, granular tobacco, tobacco leaves, and / or reconstituted tobacco. Suitable aerosol-forming agents include polyols (e.g., sorbitol, glycerol, and glycols such as propylene glycol or triethylene glycol), non-polyols (e.g., monohydric alcohols, acids such as lactic acid, glycerol derivatives, esters such as triacetin, triethylene glycol diacetate, triethyl citrate, glycerin, or vegetable glycerin). In some embodiments, the aerosol-generating agent may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. The substrate may also comprise at least one of a gelling agent, a binder, a stabilizer, and a humectant.

[0053] Figure 1 shows an aerosol generating assembly 10 comprising an aerosol generating device 11 and a consumable set 12. The consumable set 12 comprises a tobacco article 13 and a mouthpiece 14. The tobacco article 13 is intended to work with the aerosol generating device 11 and is shown in more detail in Figure 2.

[0054] Referring to Figure 1, the aerosol generating device 11 comprises a device body 15 extending along the device axis Y between a closed end 16 and an open end 17. The open end 17 provides an opening into which a tobacco article 13 can be inserted into the aerosol generating device 11. The device body 15 defines the boundary of the internal space of the aerosol generating device 11, which accommodates various elements designed to perform different functions of the aerosol generating device 11. This internal space can accommodate, for example, a battery for powering the aerosol generating device 11, a control module for controlling the operation of the aerosol generating device 11, a heating chamber 60 for heating the tobacco article 13, and so on. In the embodiment of Figure 1, only the heating chamber 60 is shown. In particular, the heating chamber 60 is designed to at least partially accommodate the tobacco article 13. In the embodiment of Figure 1, the heating chamber 60 may be located, for example, adjacent to the opening formed by the open end 17 of the device body 15. The heating chamber 60 may, for example, extend along the device axis Y and have a cup shape. The heating chamber 60 may include a heater designed to heat at least a portion of the tobacco article 13. The heater may include, for example, a pair of heating plates facing each other and designed to heat opposing walls of the tobacco article 13, as will be described in more detail below. According to other embodiments, the heater may include any other means suitable for heating the tobacco article, such as heating blades or magnetic coils.

[0055] In the embodiment shown in Figure 2, the tobacco article 13 is flat. In other words, in this embodiment, the tobacco article 13 is a flat rectangular parallelepiped extending along the article axis X between the inlet end 18 and the outlet end 19, having external dimensions L × W × D. In a typical embodiment, the length L of the article 13 along the article axis X is approximately equal to 33 mm, while its width W and depth D are approximately equal to 12 mm and 1.2 mm, respectively. According to a different embodiment, the values ​​L, W, and D can be selected within, for example, a range of ±40%. The depth D of the tobacco article 13 is formed by a pair of parallel walls 23A, 23B, hereafter referred to as side walls 23A, 23B, and the width W of the tobacco article 13 is formed by a pair of parallel walls 24A, 24B, hereafter referred to as wider walls 24A, 24B. In the embodiment shown in Figure 2, the tobacco article 13 is flat, so that each wider wall 24A, 24B is at least 5 times, and preferably 10 times, wider than, for example, each side wall 23A, 23B. The flatness of the tobacco article 13 is therefore defined by the ratio between each wider wall 24A, 24B and each side wall 23A, 23B being greater than 5, and preferably greater than 10. In some embodiments, the edges between the wider walls and the side walls 23A, 23B, 24A, 24B can be rounded. According to other embodiments, the tobacco article 13 can have any other suitable shape, for example, a cylindrical shape with a circular or elliptical cross-section.

[0056] The tobacco article 13 comprises a base portion 25 and a cooling portion 26 arranged along the article axis X. The base portion 25 may be slightly longer than, for example, the cooling portion 26. For example, the length L2 of the base portion 25 along the article axis X may be approximately equal to 18 mm, and the length L1 of the cooling portion 26 along the article axis X may be approximately equal to 15 mm. The base portion 25 defines the inlet end 18 of the article 13, and the cooling portion 26 defines the outlet end 19 of the article 13. The base portion 25 and the cooling portion 26 may be fixed to each other by a wrapper 31 extending around the article axis X. In this case, the wrapper 31 forms the side walls and wider walls 23A, 23B, 24A, 24B of the tobacco article 13. In some embodiments, the wrapper 31 is formed from the same wrapping sheet. In some other embodiments, the wrapper 31 is formed from separate wrapping sheets that wrap the portions 25, 26 separately, with one fixed to the other by any other preferred means. The wrapper 31 may include, for example, paper and / or nonwoven fabric and / or aluminum foil. The wrapper 31 may be porous or air-impermeable. In some embodiments, if the wrapper 31 includes aluminum, the aluminum can wrap only the tobacco substrate to prevent condensation leakage and / or vapor leakage. In one embodiment, the wrapper is a laminate of paper and aluminum extending along the entire length of the article axis X. In addition, the aluminum allows for better heat transfer.

[0057] The base material portion 25 of the tobacco article 13 is designed to be received into the heating chamber 60 of the aerosol generating device 11 (for example, through an opening formed by the device body 15) such that the article and the device axes X and Y coincide, as shown in Figure 1. The respective wider wall portions 23A and 23B corresponding to the base material portion 25 of the article 13 are designed to be heated by the heating chamber 60 of the aerosol generating device 11. In particular, each of these portions is designed to be in contact with a heating plate that forms a heater, as described above. In some embodiments, the corresponding portion of only one of the wider walls 23A and 23B is designed to be heated by the heater. The base material portion 25 comprises a tobacco base material containing a vaporizable material as defined above. The vaporizable material can be compressed, for example, to form a solid structure that can release an aerosol when heated. This solid structure can form, for example, a rectangular parallelepiped shape. In some embodiments, the solid structure forms aerosol channels on its surface that guide the aerosol formed by the vaporizable material. In some embodiments, the solid structure may have a corrugated shape in each cross-section. In these embodiments, the corrugated shape defines a plurality of valley regions, each valley region forming an aerosol channel as described above.

[0058] The cooling section 26 is intended to function as a cooler that cools the vapor before it is inhaled by the user. In the embodiment shown in Figure 2, the cooling section 26 is advantageously hollow overall. In other words, in this embodiment, the cooling section 26 is bounded only by a wrapper, e.g., the wrapper 31 described above, which extends around the article axis X. According to other embodiments, the cooling section 26 comprises at least one inner wall that extends along the article axis X and forms one or more airflow channels. For example, the inner wall may be entirely adjacent to the inner surface of the wrapper 31, or it may extend between a pair of lateral or wide walls 23A, 23B, 24A, 24B. In this last case, several airflow channels can be formed within the cooling section 26. The inner wall may also be formed by a core inserted into the cooling section 26. In some embodiments, the core may function as a filter element.

[0059] Figure 3 shows different embodiments of the non-hollow cooling portion 26.

[0060] In Embodiment A, the inner wall 37 is formed parallel to the side walls 23A and 23B formed by the wrapper 31. This inner wall 37 is positioned, for example, approximately midway between the side walls 23A and 23B, and divides the cooling portion 26 into two airflow channels.

[0061] In Example B, two inner walls 37A and 37B are formed parallel to the side walls 23A and 23B. In addition, two inner walls 37C and 37D are formed parallel to the wide walls 24A and 24B. Inner wall 37C extends between the side wall 23B and inner wall 37A, and inner wall 37D extends between the side wall 23A and inner wall 37B. In this case, five airflow channels are formed in the cooling section 26.

[0062] In Example C, a core formed by two tubular elements 37A and 37B is inserted into the cooling section 26. Each tubular element 37A and 37B extends along the article axis X and forms, for example, a circle in cross-section. Each tubular element 37A and 37B can come into contact with the wide walls 24A and 24B.

[0063] In Example D, a core 37 made of corrugated cardboard is inserted into the cooling section 26. The core 37 may be formed into a stable shape by an extrusion and / or rolling process. Advantageously, the core 37 is positioned inside the cooling section 26 so as to be in contact with the wide walls 24A, 24B.

[0064] Figure 4 shows different diagrams of a mouthpiece 14 fitted to engage with a tobacco article 13. The mouthpiece 14 is made from paper, for example, by injection molding. In particular, as shown in Figure 4, the mouthpiece 14 defines a recess 40 on its rear surface 38 that is fitted to receive the cooling portion 26 of the tobacco article 13. For this purpose, the recess 40 has a shape complementary to the shape of the cooling portion 26. Thus, the recess 40 may have a substantially rectangular cross-section similar to one of the tobacco articles 13. In some embodiments, the recess 40 may include a sealing member configured to engage with the outer surface of the cooling portion 26. As shown in part C of Figure 4, the recess 40 is fitted to receive the cooling portion 26 of the tobacco article 13 substantially in its entirety, lacking a base material portion 25. The recess 40 is extended by a channel 41 that opens to the front surface 39 of the mouthpiece 14, opposite the rear surface 38 of the mouthpiece 14. In other words, the recess 40, together with the flow path 41, forms a through-hole for the mouthpiece 14 that extends between the rear surface 38 and the front surface 39.

[0065] The mouthpiece 14 may further define a stopper in the transition zone between the recess 40 and the flow path 41. The stopper prevents the tobacco article 13 from traversing the entire mouthpiece 14 while it is being inserted from the rear surface 38. The stopper may be formed by the flow path 41 having a cross-section slightly different from that of the recess 40. For example, the cross-sectional area of ​​the flow path 41 may be smaller than that of the recess 40. Thus, a shoulder can be formed between the recess 40 and the flow path 41. The exit end 19 of the tobacco article 13 can therefore abut against the shoulder, preventing it from traversing the flow path 41. According to another embodiment, the stopper is formed by a projection in the transition zone.

[0066] In the embodiment shown in Figure 4, the recess 40 is hollow overall. In some other embodiments, the recess 40 may have one or more inner walls similar to the inner walls described with reference to Figure 3 (i.e., 37, 37A-37D). In this case, the cooling portion 26 of the tobacco article 13 may be hollow overall or may have inner walls positioned so as not to interact with or collide with the inner walls of the recess 40. In addition, the inner walls of the recess 40 form a gap with the sides that define the boundary of the recess 40 so that the wrapper 31 of the tobacco article 13 can be inserted into the gap while the tobacco article 13 is inserted into the recess 40. For this purpose, the inner walls of the recess 40 may be fitted into the transition zone between the recess 40 and the flow path 41. In this way, the inner walls of the recess 40 can support (i.e., hold open) the cooling portion 26 of the tobacco article 13, which may be hollow overall or partially as described above. In some embodiments, the inner wall of the recess 40 can extend to the flow path 41 of the mouthpiece 14, and / or the flow path 41 itself can form an additional cooling zone independent of the tobacco article 13.

[0067] Figure 5 schematically shows a pack of tobacco articles 50 comprising multiple tobacco articles 13 and individual mouthpieces 14. The mouthpieces 14 can be used with each of the tobacco articles 13. In particular, the recesses 40 of the mouthpieces 14 are adapted to receive the cooling portions 26 of each of the tobacco articles 13 in the pack of tobacco articles 50. According to other embodiments, two or more mouthpieces 14 are included in the pack of tobacco articles 50.

[0068] When using the product, the user can purchase a pack of tobacco articles 50, for example, as shown in Figure 5. The user then removes the mouthpiece 14 and tobacco article 13 from the pack of tobacco articles 50. The user then inserts the cooling portion 26 of the tobacco article 13 into the recess 40 from the rear surface 38 of the mouthpiece 14. The user then inserts the base portion 25 of the tobacco article 13 into the aerosol generating device 11. The rear surface 38 of the mouthpiece 14 closes the open end 17 of the device body 15, and the aerosol generating device 11 is ready for use. After the vaping session, the mouthpiece 14 can be detached from the tobacco article 13 and stored in the pack of tobacco articles 50 until it is used with another tobacco article 13.
