Description

Technical Field

[0001] This invention relates to the tobacco industry, and specifically to rod-shaped multi-segment articles that define or are intended to define smoking articles or articles for generating aerosols. More specifically, this invention relates to a multi-segment article that can be penetrated by a heating element (e.g., pin-shaped or needle-shaped) of a heating device (e.g., an electronic cigarette).

[0002] In other words, the present invention relates to the field of heated non-burning (HNB) smoking devices. Background Technology

[0003] Typically, articles of this type include an aerosol-generating segment near the relevant end, which releases aerosols upon heating. This aerosol-generating segment may contain, for example, tobacco strips or tobacco-flavored or nicotine-based materials, or may contain rolled-up tobacco sheets or tobacco-flavored or nicotine-based materials. Alternatively, the aerosol-generating segment may be formed from tobacco fragments or contain tobacco-flavored or nicotine-based materials, or may contain cut tobacco. Generally, aerosol-generating segments capable of releasing aerosols upon heating can comprise substrates of any organic origin, particularly plant-derived substrates (e.g., tobacco, cotton, flax, canola, cellulose, alginate, paper).

[0004] In the field of reference of this invention, in order to generate a user-inhalable aerosol, the prior art teaches that a heating element of a heating device (e.g., an electronic cigarette) is used to pass through the aerosol generating segment.

[0005] Therefore, once aerosol generation is complete, it is necessary to remove the heating element from the aerosol generation segment. However, extraction may cause portions of the aerosol generation segment (e.g., powder, tobacco fractions, ash) to be pulled and subsequently dispersed into the environment outside the article. This dispersion is enhanced if the aerosol generation segment includes gathered tobacco fragments or cut tobacco or tobacco strips (or those containing tobacco flavor or nicotine-based flavor) that are compressed where necessary but not anchored in any way to the outer packaging of the article.

[0006] To limit potential dispersion that could harm the electronic heating device and annoy the user, an end segment is provided in the article according to the invention. This end segment is positioned at the end of the article near the aerosol-generating segment and can also be penetrated by the heating element of the heating device. In particular, the end segment is configured to retain any portion of the aerosol-generating segment that is pulled out during the removal of the heating element from the article.

[0007] In particular, it is known to manufacture end segments with holes or slots throughout their cross-section, in which the heating element of the heating device can be slidably inserted / removed, such that the removal of the heating element through the holes or slots greatly limits the dispersion (entry into the environment outside the article) of the aerosol-generating segment. This approach is known from patent EP2797450B1. Summary of the Invention

[0008] The applicant has found that this approach can be further improved, particularly in terms of production simplicity. The production of end segments with holes or slots requires a considerably high level of precision, as the holes or slots must be positioned and sized in a manner compatible with the heating device and, in particular, with the positioning of the corresponding heating element. In other words, complex and unconventional machinery is required, which, if necessary, must be integrated into the production line, thereby increasing processing time and costs.

[0009] Therefore, the object of the present invention is to provide an article having an end segment that replaces the prior art, which allows for simplified production and improved efficiency.

[0010] The applicant has found that including an insert in the end segment, defined by at least one gathered sheet or web, preferably but not necessarily obtained by folding and / or embossing and / or rolling the sheet or web, greatly simplifies production because conventional continuously operating machines, especially those with shaped beams, can be used for this production.

[0011] Therefore, the indicated technical objective and the specified objective are achieved by a multi-segment article of article including the technical features described in claim 1 and / or in one or more dependent claims. Attached Figure Description

[0012] The present invention will now be described with reference to the accompanying drawings, which illustrate non-limiting embodiments of the invention, wherein:

[0016] - Figures 9 to 11Cross-sections of different embodiments of the insert included in the rod-shaped multi-segment article according to the invention are shown.

[0017] In the accompanying drawings, the number 1 indicates the entire rod-shaped multi-segment article according to the invention. Detailed Implementation

[0018] The term "bar-shaped multi-segment article" refers to a bar-shaped article that is divided into multiple segments and is defined or intended to define a smoking article, particularly one that is suitable for forming a smoking article that can generate an aerosol by heating.

[0019] like Figures 1 to 4 As shown, article 1 extends along the corresponding extension axis “X” between its opposite ends 1a and 1b.

[0020] refer to Figures 1 to 4 Article 1 includes a plurality of segments 2, 3, 4, 5 continuously positioned along an extension axis “X”, and an outer wrapping 6 positioned around the extension axis “X” and in contact with the segments 2, 3, 4, 5 to wrap them and connect them to each other.

[0021] refer to Figures 1 to 4 The outer wrapping 6 is made of a single wrapping material sheet. According to a variant embodiment not shown, the outer wrapping 6 may be formed of multiple wrapping material sheets, each wrapping material sheet wrapping around a portion of segments 2, 3, 4, 5 and having overlapping areas; for example, a first wrapping material sheet may wrap segments 2, 5, 4, and a second wrapping material sheet may wrap segment 3 and a portion of segment 4 (overlapping with the first wrapping material sheet). According to another example, the first wrapping material sheet may wrap segments 3, 4, 5, and the second wrapping material sheet may connect a set of segments 3, 4, 5 wrapped by the first wrapping material sheet to segment 2; therefore, according to this embodiment, the second wrapping sheet wraps around segment 2 and overlaps with the first wrapping sheet (the overlapping area may vary).

[0022] According to the illustrated embodiment, the article 1 is at least divided into a filter segment 2, an end segment 3, and additional segments 4 and 5 inserted between the filter segment 2 and the end segment 3, designed for forming and processing aerosols. These additional segments include an aerosol-generating segment 4 made of a material suitable for generating aerosols by heating, and preferably include at least one tubular segment 5. Thus, the filter segment 2, the end segment 3, the aerosol-generating segment 4, and the tubular segment 5 are continuously positioned along an extending axis “X”.

[0023] More specifically, the end segment 3 and the filter segment 2 define the ends 1a and 1b of the article 1.

[0024] The aerosol generating segment 4 is positioned close to the end segment 3; in other words, the aerosol generating segment 4 is positioned close to the end 1a of the article 1 defined by the end segment 3.

[0025] At least one tubular segment 5 is inserted between the aerosol generating segment 4 and the filter segment 2.

[0026] The aerosol-generating segment 4 may comprise a general material suitable for releasing aerosols upon heating, such as a tobacco stick or material containing a tobacco flavor or nicotine-based flavor, or comprising a rolled-up tobacco sheet or containing a tobacco flavor or nicotine-based flavor. According to another example, the aerosol-generating segment 4 may comprise cut tobacco or tobacco fragments or containing a tobacco flavor or nicotine-based flavor. Typically, the aerosol-generating segment 4 may comprise a substrate of any organic origin, particularly a plant-based substrate (e.g., tobacco, cotton, flax, canola, cellulose, alginate, paper).

[0027] On the other hand, at least one tubular segment 5 can serve as a spacer between the filter segment 2 and the aerosol generating segment 4, and / or serve as a cooling element suitable for limiting the temperature reduction of the aerosol generated by the user's suction and by heating the aerosol generating segment 4.

[0028] Alternatively, the tubular segment 5 is a spacer followed by a cooling segment with a non-tubular structure.

[0029] according to Figures 1 to 4 In the embodiment shown, the tubular segment 5 is divided into a pair of parts 5a and 5b, which are respectively adapted to perform the functions of a spacer element and a cooling element.

[0030] The article 1 manufactured in this way can be inserted into the heating device 300, thereby defining... Figures 1 to 4 The aerosol generation system 200 is schematically shown in the figure.

[0031] Specifically, the heating device 300 includes a cylindrical housing 301 configured to at least partially receive the article 1, and a heating element 302 positioned within the cylindrical housing 301. The end segment 3 and the aerosol generating segment 4 can be penetrated by the heating element 302, such that the heating element 302 contacts and heats the material of the aerosol generating segment 4, thereby generating an aerosol (which can be inhaled by a user).

[0032] Therefore, the heating element 302 has an axial extension for preferably being inserted into the end segment 3 and the aerosol generating segment 4 along the extension axis "X" of the article 1. Thus, in the usage configuration, the article 1 is inserted into the cylindrical housing 301, and the heating element 302 is inserted into the end segment 3 and the aerosol generating segment 4.

[0033] To ensure proper insertion into the end segment 3 and the aerosol generating segment 4, the heating element 302 has an elongated shape and is preferably made in the form of a needle or pin. Alternatively, it can be in the shape of a flat plate.

[0034] According to an alternative embodiment not shown, the heating device 300 may include two or more heating elements 302 that extend axially and are preferably parallel to each other (and parallel to the extension axis X). Thus, in a configuration of use, the article 1 is inserted into the cylindrical housing 301, and the plurality of heating elements 302 are inserted into the end segment 3 and the aerosol generating segment 4.

[0035] According to an advantageous aspect of the invention, the end segment 3 includes an outer tubular element 3a and an insert 3b defined by at least one folded sheet or web positioned inside the outer tubular element 3a, thereby allowing for simplified production that can be performed using conventional machines.

[0036] The techniques used to manufacture the insert 3b and the outer tubular element 3a (such as the production of gathered sheets or webs and the production of tubular elements) are widely used in the tobacco industry, allowing the end segment 3 to be advantageously manufactured entirely through an efficient production process, which can be performed continuously by conventional machines with forming beams. In other words, there is no need to integrate “specific” machines optimized for the production of the end segment 3 into the production line of article 1. Gathering can be performed by conventional machines equipped with devices for feeding the webs and, for example, devices for gathering in the form of converging elements.

[0037] Preferably, and according to the illustrated embodiment, the insert 3b is defined by a single gathered web or sheet. Alternatively, the insert 3b may be defined by two or more gathered webs or sheets.

[0038] In detail, the insert 3b is made of at least one sheet or web, which includes a predetermined pattern on its surface to weaken creases in order to facilitate the folding of the sheet or web.

[0039] The term "predetermined pattern" refers to a predetermined geometric shape, particularly a geometric shape that repeats along the surface of a sheet or web, such as a series of longitudinally arranged, continuous, or discontinuous notches (preferably not through notches). In particular, the predetermined pattern defined on the sheet or web of material is intended to facilitate the subsequent closing of the web or sheet to form the insert 3b.

[0040] Preferably, the predetermined pattern is obtained by subjecting the sheet or web to folding, curling, and / or embossing operations. In other words, the insert 3b is formed from at least one sheet or web of material that is folded, curled, and / or embossed, and then gathered.

[0041] The term curling and / or embossing operation refers to the process of treating a sheet or web of material (e.g., using a pair of rollers) to define the aforementioned predetermined pattern on the surface of the sheet or web.

[0042] It should be understood that the predetermined pattern may be obtained only on a portion of the surface of the web or sheet; in this case, some areas of the web or sheet will lack the pattern, i.e., they will not undergo any curling and / or embossing operations. Preferably, these untreated areas can be used as areas for anchoring the insert 3b to the outer tubular element 3a, as described in more detail below.

[0043] If the insert 3b is defined by two or more gathered webs or sheets, they may all have the same predetermined weakening pattern or include different predetermined weakening patterns; alternatively, some webs or sheets may have the predetermined weakening pattern, while others may not have the predetermined weakening pattern.

[0044] For more details, see the reference. Figure 5 and Figure 6 The insert 3b has adjacent portions that are bent or folded relative to each other, and is shaped to at least partially occupy the cross-section of the outer tubular element 3a. Thus, the cross-section of the end segment 3 specifically includes the area occupied by the insert 3b and the area not occupied by the insert 3b, which preferably does not contain any other type of filler.

[0045] In other words, insert 3b can define blank spaces, which are defined by walls or partitions defined by the gathered sheet or web. However, in the case of highly compacted gathering, these blank spaces may be essentially non-existent.

[0046] The term "cross section" refers to a section obtained in a plane perpendicular to the extension axis "X".

[0047] More specifically, the adjacent portions of the gathered sheet or web that are bent or folded relative to each other are positioned in contact with each other, and at least around the central region 30 positioned around the extending axis "X", are positioned at a distance of less than 3 mm from each other. Thus, the sheet or web can be gathered in a loose manner, i.e., not fully compressed within the outer tubular element 3a.

[0048] Specifically, the insert 3b (i.e., the gathered web or sheet) is shaped such that the end segment 3 can be penetrated by the heating element 302 (or multiple heating elements 302) positioned parallel to the extension axis "X" of the article 1 through the radial deformation and / or movement of the gathered web or sheet, thereby ensuring convenient insertion / removal of the heating element 302.

[0049] More specifically, the end segment 3, particularly the insert 3b, is shaped to interfere with or contact the heating element 302 (or multiple heating elements 302) which is coaxially inserted with the extension axis “X” and has a lateral dimension between 0.2 mm and 5 mm, such that the insertion of the heating element 302 determines the redistribution of the gathered web or sheet within the cross-section of the end segment 3 by radial deformation and / or movement.

[0050] The deformation and / or radial movement are located at least in the central portion 30 of the insert 3b, with the extended axis “X” passing through the central portion 30.

[0051] Therefore, in the usage configuration of article 1, that is, when article 1 is inserted into the cylindrical housing 301 of heating device 300, heating element 302 is at least partially in contact with insert 3b.

[0052] Specifically, refer to Figure 5 and Figure 6 Insert 3b defines a shape with at least a partial random tendency in the cross-section.

[0053] For example, if the insert 3b is made by inserting a web or sheet into the converging element, its convergence (and therefore its cross-sectional shape once inserted into the outer tubular element 3a) is unpredictable or cannot be repeated in a precisely controllable manner in any case.

[0054] According to one aspect of the invention, the insert 3b has a predominantly curved shape in cross-section, and preferably a fully curved shape. This choice is particularly possible from previously unrolled or folded sheets.

[0055] The term "main" refers to the majority of insert 3b.

[0056] More specifically, the insert 3b includes a series of curvatures having convex and concave surfaces, which are preferably oriented in an alternating manner.

[0057] For example, according to Figure 6 and Figure 8 In the embodiment shown, the insert 3b has a shape in cross-section that is mainly formed by multiple rings.

[0058] On the other hand, according to Figure 5 and Figure 7 In the illustrated embodiment, the insert 3b has a shape in cross-section primarily defined by fold lines having multiple fold lines "P" that define corresponding folded surfaces "F" of the sheet or web. Preferably, the folded surfaces "F" are at least partially separated from each other, thereby partially occupying the cross-section of the outer tubular element 3a.

[0059] The insert 3b may also have a hybrid structure defined by at least a portion equipped with a ring and at least a portion mainly defined by a broken line. According to Figures 9 to 11 In the variant embodiment shown, the insert 3b may be shaped such that it does not interfere with (or at least substantially does not interfere with) the insertion of the heating element 302, in particular such that the heating element 302 does not come into contact with the insert 3b after the heating element 302 is inserted, or in any case, the insert 3b is not damaged / deformed by the heating element 302.

[0060] according to Figures 9 to 11 In the variant embodiment shown, the insert 3b may have a three-dimensional shape that is confined to an annular region spaced apart from the extension axis “X”. This annular region defines a central region without the shaped insert (3b) and preferably has a diameter between 3 mm and 6 mm (preferably equal to about 4 mm) and / or a minimum lateral dimension between 3 mm and 6 mm.

[0061] like Figures 9 to 11 As shown, the insert 3b has an annular extension that is shaped to avoid interfering with or coming into contact with the heating element 302 (or multiple heating elements 302) that is inserted coaxially with the extension axis "X".

[0062] In fact, such as Figures 9 to 11 As shown, the gathered sheet or web of the defining insert 3b is configured to define an unobstructed central space extending around the extension axis "X", such that the gathered web does not interfere with or come into contact with at least one heating element 302 inserted coaxially with the extension axis "X".

[0063] In other words, the insert 3b is shaped such that the central region 30 of the cross-section of the end segment 3, positioned around the extension axis "X", is unobstructed. Therefore, the cross-section of the end segment 3 specifically includes the region occupied by the insert 3b and the region coinciding with the central region 30 that is not occupied by the insert 3b, which preferably does not contain any other type of filler.

[0064] According to one aspect of the invention, the insert 3b may have a plurality of contact areas 31 with the external tubular element 3a (in Figure 5 and Figure 8 (As shown in the image).

[0065] Preferably, the contact areas are distributed at an angle around the extending axis “X” and / or spaced apart from each other (in particular in a manner that is at least partially random), each defined by the cross-sectional shape adopted by the insert 3b.

[0066] Preferably, the contact area 31 defines an attachment area between the insert 3b and the outer tubular element 3a, more preferably by adhesive bonding. In particular, the contact area 31 contacts the inner wall 100 of the outer tubular element 3a and is preferably adhesively bonded to the inner wall 100.

[0067] Therefore, the outer tubular element 3a and the insert 3b are connected to each other and are integral (e.g., glued together), thereby ensuring the stability of the end segment 3 when the heating element 302 is withdrawn from the article 1. This results in the robustness of the end segment 3 and effectively retains portions of the aerosol-generated segments 4 pulled by the heating element 302 when the heating element 302 is withdrawn from the article 1 (through the insert 3b acting as a barrier for these portions).

[0068] according to Figure 7 and Figure 8 In the preferred embodiment shown, the contact area 31 may be defined by the lateral end edges 32 of the gathered sheet or web, which are preferably bent to adhere to the inner wall 100 of the outer tubular element 3a. The insert 3b formed in this way may be made using a converging element provided with grooves configured to exclude the lateral end edges of the sheet or web from the gathering.

[0069] refer to Figure 7 The insert 3b is formed of a sheet or web that undergoes the formation of a longitudinal weakening line (i.e., curling) at least at the central longitudinal strip of the sheet or web. At the side longitudinal strip, next to the central longitudinal strip, the sheet or web defines a side end edge 32, which has no weakening line, and adhesive is applied to the side end edge 32 to secure the side end edge 32 to the inner wall 100 of the outer tubular element 3a.

[0070] refer to Figures 9 to 11 Insert 3b is configured such that it defines a shape with an ordered and repeating tendency around the extending axis “X” in the cross section.

[0071] Preferably, according to Figures 9 to 11 In one embodiment, the insert 3b is formed from a sheet or web of material that undergoes the formation of longitudinal weakening lines (i.e., curling) and / or the formation of pre-shaped material over the entire width of the sheet or web, for example, placed in a planar manner with protrusions and recesses corresponding to the radial trend of the insert.

[0072] refer to Figure 9 The sheet or web has a generally triangular wavy profile in cross-section, with multiple tops appearing successively in succession. In this case, the outward-facing tops define a contact area 31 between the insert 3b and the tubular element 3a.

[0073] The contact areas 31 are distributed at an angle around the extended axis "X" and are spaced apart from each other.

[0074] The contact area 31 defines an attachment area between the insert 3b and the outer tubular element 3a, more preferably by adhesive bonding.

[0075] Specifically, the contact area 31 contacts and is preferably glued to the inner wall 100 of the outer tubular element 3a. According to a first possibility, an adhesive material (e.g., vinyl glue) is applied to the top of the insert 3b intended to be fixed to the inner wall 100 of the outer tubular element 3a. Alternatively, instead of applying glue to each top of the insert 3b, glue can be applied evenly to the entire inner wall 100 of the outer tubular element 3a, such that each top is glued to the inner wall 100 in any case.

[0076] refer to Figure 10 The sheet or web has a substantially square wave profile in its cross-section, in which multiple substantially straight sections appear successively in succession. In this case, these sections define the contact area 31 between the insert 3b and the tubular element 3a.

[0077] The contact areas 31 are distributed at an angle around the extended axis "X" and are spaced apart from each other.

[0078] The contact area 31 defines an attachment area between the insert 3b and the outer tubular element 3a, more preferably by adhesive bonding.

[0079] Specifically, the contact area 31 contacts and is preferably glued to the inner wall 100 of the outer tubular element 3a. According to a first possibility, an adhesive material (e.g., vinyl glue) is applied to the portion of the insert 3b intended to be fixed to the inner wall 100 of the outer tubular element 3a. Alternatively, instead of applying glue to each of the aforementioned portions of the insert 3b, glue can be applied uniformly to the entire inner wall 100 of the outer tubular element 3a, such that each portion is glued to the inner wall 100 in any case.

[0080] refer to Figure 11 The sheet or web has essentially two substantially continuous straight sections in cross-section, with an alternating profile of edges or tops. In this case, the substantially straight sections define the contact area 31 between the insert 3b and the tubular element 3a.

[0081] The contact areas 31 are distributed at an angle around the extended axis "X" and are spaced apart from each other.

[0082] The contact area 31 defines an attachment area between the insert 3b and the outer tubular element 3a, more preferably by adhesive bonding.

[0083] Specifically, the contact area 31 contacts and is preferably glued to the inner wall 100 of the outer tubular element 3a. According to a first possibility, an adhesive material (e.g., vinyl adhesive) is applied to a substantially straight portion of the insert 3b intended to be fixed to the inner wall 100 of the outer tubular element 3a. Alternatively, instead of applying adhesive to each substantially straight portion of the insert 3b, adhesive can be applied uniformly to the entire inner wall 100 of the outer tubular element 3a, such that each top is glued to the inner wall 100 in any case. Preferably, the insert 3b has a single-layer structure. However, the insert 3b may have a multi-layer structure.

[0084] Preferably, at least the insert 3b is made of organic material, thereby ensuring the sustainability of article 1.

[0085] Preferably, at least the insert 3b is made of a material that does not release substances when heated (i.e., when the heating element 302 of the heating device 300 is inserted into the article 1, particularly into the end segment 3 and the aerosol generating segment 4), thereby ensuring the health and safety of the user.

[0086] Preferably, at least the insert 3b is made of a material that can be heated to 350°C to resist combustion or that, when heated within this temperature range, cannot release substances considered harmful or toxic, thereby ensuring the health and safety of the user.

[0087] Additionally or alternatively, according to embodiments not shown, heating element 302 (or multiple heating elements 302) may include a portion of insulating material intended to be axially positioned at the end segment 3 during use. In this way, only the aerosol-generating segment 4 is heated by the heating element 302.

[0088] More preferably, at least the insert 3b is made of a physically heat-resistant material that does not burn, incinerate or break when heated, thus significantly limiting the intake of any powder and / or material into the environment outside the article by removing the heating element 302 from the article.

[0089] Preferably, at least the insert 3b is made of a biodegradable and / or compostable material, thereby ensuring the sustainability of the product 1.

[0090] For example, at least the insert 3b is made of a material selected from: paper, cellulose, cellulose derivatives, alginate, plastic materials, metals (e.g., aluminum or steel), carbon compounds, and non-metallic materials (e.g., ceramics). In the case of ceramic materials, the insert 3b is obtained by techniques other than folding, embossing, and curling.

[0091] According to possible implementations, the insert 3b and the outer tubular element 3a are made of the same cellulose-based material (in the form of sheets or webs). In this case, nicotine or other flavorings are also added to the material intended to form the insert.

[0092] In other words, the outer tubular element 3a and the insert 3b are made of the same material, and only in the case of the insert 3b is nicotine or other flavorings added to the material.

[0093] Alternatively, both the outer tubular element 3a and the insert 3b can be made of tobacco-based or cellulose-based sheets or webs to which nicotine or other flavorings can be added.

[0094] According to one aspect of the invention, the sheet or web forming the insert 3b may have a plurality of longitudinal lines of an adhesive material (e.g., vinyl ester adhesive) such that when the sheet or web is gathered to form the actual insert 3b, some portions thereof are bonded together at the lines, thereby imparting strength and rigidity to the insert 3b. According to one aspect of the invention, the longitudinal lines may be formed on the sheet or web before the formation of longitudinal weakening lines (if present), or they may be formed on the sheet or web after the formation of the longitudinal weakening lines.

[0095] Product 1 can be based on Figures 1 to 4 The different embodiments shown are manufactured.

[0096] according to Figure 1 In the first embodiment of the product 1 shown, the end segment 3 is positioned to contact the aerosol generating segment 4.

[0097] More specifically, according to the first embodiment, the outer tubular element 3a is positioned to contact the aerosol generating segment 4, while the insert 3b extends the entire axial dimension of the end segment 3, that is, extends along the extension axis "X" of the end segment 3. Preferably, the insert 3b is also positioned to contact the aerosol generating segment 4.

[0098] The external tubular element 3a and / or insert 3b can also preferably be anchored to the aerosol-generating segment 4 and / or the outer covering 6 by gluing and / or fixing.

[0099] Preferably, the insert 3b is also positioned flush with the end 1a of the article 1.

[0100] according to Figure 2In the second embodiment of the illustrated article 1, the end segment 3 is positioned to contact the aerosol-generating segment 4 at the outer tubular element 3a, while the insert 3b (shorter in the axial direction) is spaced apart from the aerosol-generating segment 4, thereby defining a gap region 7 between the insert 3b and the aerosol-generating segment 4. Thus, the gap region 7 is defined radially (i.e., around the extending axis "X") by the outer tubular element 3a and axially (i.e., along the extending axis "X") by the insert 3b and the aerosol-generating segment 4. The outer tubular element 3a can also be anchored to the aerosol-generating segment 4 and / or the outer covering 6 by gluing and / or fixing.

[0101] Preferably, the insert 3b is also positioned flush with the end 1a of the article 1.

[0102] according to Figure 3 In the third embodiment of the article 1 shown, both the outer tubular element 3a and the insert 3b are spaced apart from the aerosol generating segment 4, such that a gap region 7' ​​is defined between the end segment 3 and the aerosol generating segment 4. Furthermore, the outer tubular element 3a and the insert 3b have the same axial length. Therefore, the gap region 7' ​​is defined radially (i.e., around the extension axis "X") only by the outer covering 6, and axially (i.e., along the extension axis "X") by the end segment 3 and the aerosol generating segment 4. Preferably, the insert 3b is also positioned flush with the end 1a of the article 1.

[0103] like Figure 3 As shown, the length of the spacer region 7' ​​(measured along the extension axis X) is substantially equal to the length of the terminal segment 3 (measured along the extension axis X). According to a variant embodiment, the length of the spacer region 7' ​​(measured along the extension axis X) is less than the length of the terminal segment 3 (measured along the extension axis X).

[0104] according to Figure 4 The fourth embodiment shown includes a tubular or annular spacer segment 8 inserted between the terminal segment 3 and the aerosol generating segment 4. The spacer segment 8 is preferably adjacent (i.e. in contact) to at least one of the aerosol generating segment 4 and the terminal segment 3, and more preferably adjacent to both.

[0105] The spacer segment 8 can also preferably be anchored to the external tubular element 3a and / or insert 3b and / or aerosol-generated segment 4 and / or outer covering 6 by gluing and / or fixing.

[0106] More specifically, the spacer segment 8 is hollow, meaning it has an unfilled cross-section.

[0107] More specifically, the spacer segment 8 is formed in the form of a tubular or annular element and has a blank cross-section, that is, it is not occupied by the inner wall or components.

[0108] For example, the diameter of the spacer segment 8 is preferably equal to the diameter of the other segments, while the thickness of the tubular wall defining the spacer segment is between 0.1 mm and 2 mm (or even more preferably between 0.1 mm and 1 mm).

[0109] Therefore, the spacer segment 8 acts as a reinforcement for the outer covering 6, without any type of filler, thus giving the article 1 greater stability and strength.

[0110] like Figure 4 As shown, the length of the spacer segment 8 (measured along the extension axis X) is substantially equal to the length of the terminal segment 3 (measured along the extension axis X). According to a variant embodiment, the length of the spacer segment 8 (measured along the extension axis X) is less than the length of the terminal segment 3 (measured along the extension axis X). Preferably, the spacer segment 8 is a loop with a length between 1 mm and 8 mm.

[0111] Furthermore, preferably, also in the fourth embodiment, the insert 3b has the same axial length as the outer tubular element 3a and is positioned flush with the end 1a of the article 1.

[0112] The present invention achieves the above-mentioned objectives by eliminating the disadvantages of the prior art: in this regard, it should be noted that the outer tubular element 3a and the insert 3b ensure improved production efficiency because they can be manufactured using conventional machines. Therefore, the present invention allows for reductions in the production time and cost of article 1.
