The term "aerosol-generating article" refers to a smoking article. Which generates an aerosol that is directly inhalable into the user's lungs through the user's mouth. Alternatively, the aerosol-generating article may be a tobacco article which generates a nicotine-containing aerosol which is directly inhalable into the lungs through the mouth of the user.
An "aerosol-generating device" in embodiments of the present invention is used to describe a device that interacts with an aerosol-forming substrate of an aerosol-generating article to generate an aerosol. The aerosol-generating device may be a smoking article, the aerosol-forming substrate of the remaining aerosol-generating articles interacting to generate an aerosol which is inhalable directly into the user's lungs through the user's mouth. The aerosol-generating device may be for a holder of a smoking article. And, for the avoidance of doubt, the term "heating element" is intended to mean one or more heating elements.
Compared with the prior art, the aerosol-forming substrate containment device provided by the present invention has the following advantages:
in the above-described solution, since the distal end of the heated non-combustible aerosol-generating article is provided with the wrapping member, in other words, the wrapping member spans the distal end and is adapted to partially or fully wrap an end face of the aerosol-forming substrate near the distal end, it is possible to limit the inability of the aerosol-forming substrate to leave the packaging structure of the aerosol-generating article or the aerosol-generating article before being used, and thus it is possible to keep the aerosol-forming substrate free from contamination while holding the aerosol-forming substrate. In addition, since the wrapper member is arranged to include regions of differing ease of rupture, it is relatively more labour-saving and convenient for a user to use the wrapper member in a region of relatively greater ease of rupture at the start of use of the aerosol-generating article, and at the end of use, i.e. when separating the heating element from the aerosol-forming substrate, it is also possible to wipe the heating element clean with the edges of the region of relatively lesser ease of rupture, making the heating element cleaner for further use. In addition, since the relatively difficult to break region is not punctured when the aerosol-generating article is in use, aerosol-forming substrate that falls off during heating and during separation of the heating element may be carried to prevent the aerosol-forming substrate from falling into the aerosol-generating device.
In order that the foregoing and other objects, features, and advantages of the invention will be readily understood, a preferred embodiment of the invention will be hereinafter described in detail with reference to the accompanying drawings.

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. While the invention will be described in conjunction with the preferred embodiments, it is not intended that features of the invention be limited to these embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
Through a great deal of experimental research of the inventor, the problems of low convenience and low cleanness of the existing heating non-combustion aerosol generating product are found.
For the reasons the inventors have found to solve the above problems, embodiments of the present invention provide a distal end provided with a cladding member that can secure an aerosol-forming substrate whilst keeping the aerosol-forming substrate free of contamination. Moreover, the broken edge can be used for wiping and cleaning the heating element, so that the heating element is cleaner and is convenient to use next time. In addition, it is also possible to carry a falling aerosol-forming substrate to prevent the aerosol-forming substrate from falling into the aerosol-generating device.
For a better understanding and enabling disclosure to those of ordinary skill in the art, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Figure 1 shows a longitudinal section through a heated, non-combustible aerosol-generating article in an embodiment of the invention, and as can be seen with reference to figure 1, in a three dimensional view, the packaging structure 1 of the heated, non-combustible aerosol-generating article also takes the form of a column or cartridge, as the aerosol-generating article may take the form of a column or cartridge, and the aerosol-generating article comprises: a mouth end 12 and a distal end upstream of the mouth end 12, and the aerosol-generating article has an aerosol-forming substrate (not shown) located upstream of the mouth end 12 within the column or cartridge. In particular, the mouth end 12 is the end at which a user draws on, and a section near the distal end is arranged to receive an aerosol-forming substrate.
Also, in a specific implementation, with continued reference to fig. 1, the distal end is provided with a wrapping member 11, the wrapping member 11 spanning the distal end and being adapted to partially or fully wrap an end face of the aerosol-forming substrate proximate the distal end, and the wrapping member 11 together with members wrapping other parts of the aerosol-generating article may constitute a packaging structure 1. It should be noted that the covering member 11 may be a completely enclosed structure, or may be an approximately enclosed structure, for example, an entirely enclosed structure with a hollow-out middle portion. The cover member 11 is arranged to include regions of different ease of rupture, i.e. the cover member 11 does not exhibit the same strength throughout, but rather has regions of greater ease of rupture, and regions of lesser ease of rupture, and a user may employ the rupture element to rupture the regions of greater ease of rupture when using or applying heat to a non-combustible aerosol-generating article, with relatively more effort and convenience to effect or facilitate heating of the aerosol-forming substrate by the heating element to produce an aerosol for the user to apply. When the use is finished, i.e. when the heating element is separated from the aerosol-forming substrate, the user may also wipe the heating element clean with the edge of the region that is more difficult to break, making the heating element cleaner for the next use. In other words, after the tobacco rod has been used up, the user may scrape the heating element with the distal, damaged crack edge, preventing the heating element from sticking to the aerosol-forming substrate, keeping it clean.
In addition, since the more difficult to break region may remain unbroken during use of the aerosol-generating article, the more difficult to break region may carry aerosol-forming substrate that falls off during heating and during separation of the heating element to prevent the aerosol-forming substrate from falling off into the aerosol-generating device.
In a specific embodiment, the packaging structure 1 may be a hollow cylinder, in which the end filled with the aerosol-forming substrate is the covering member 11 and the mouthpiece end is open. By cylindrical it is meant that the overall outer shape of the packaging structure 1 is cylindrical, or may be approximately cylindrical, and the hollow structure of the packaging structure 1 is used to encase or fill aerosol-forming substrates and other components of aerosol-generating articles. Furthermore, the aerosol-forming substrate may be an outer wall or wrapper structure that is wrapped and then filled into the aerosol-generating article, or may be directly filled into the outer wall or wrapper structure of the aerosol-generating article. The term "post" as used herein may refer to an element having a substantially cylindrical or near-cylindrical shape or other cylindrical shape. The term "cartridge" as used herein may mean a structure having an outer wall that is substantially cylindrical, an interior that has a space filled with an aerosol-forming substrate and an element that has a cooling, filtering, etc. effect. And the posts or cartridges in embodiments of the invention may be manufactured in different sizes depending on their intended user.
It should be noted that, in the embodiment of the present invention, the number of the regions with different degrees of difficulty in being ruptured is not limited, and a person skilled in the art may set a specific number according to actual needs, for example, three regions with different degrees of difficulty in being ruptured may be set, or four regions with different degrees of difficulty in being ruptured may be set, and a certain number of regions with the same degree of difficulty in being ruptured may exist in the three regions or the four regions, and the setting positions of the regions with different degrees of difficulty in being ruptured may be symmetrical or asymmetrical.
For easy understanding, referring to fig. 2, three regions are provided on the covering member 11, which are the region 211, the region 212 and the region 213, the region 213 is a region of the whole covering member 11 except the region 211 and the region 212, the regions 211 and 212 are broken with the same difficulty, the regions 213 and 211 and 212 are broken with different difficulty, the regions 211 and 212 are easier to be broken by a user using a breaking element with respect to the region 213, and the regions 211 and 212 are symmetrically arranged.
Referring to fig. 3, the covering member 11 is provided with four regions, which are a region 311, a region 312, a region 313 and a region 314, the region 314 is a region of the whole covering member 11 except the region 311, the region 312 and the region 313, the regions 311, the region 312 and the region 313 are broken with the same difficulty, the region 314 is different from the regions 311, the region 312 and the region 313 in the difficulty, the regions 311, the region 312 and the region 313 are more easily broken by a user using a breaking element with respect to the region 314, and the regions 311, the region 312, the region 313 and the region 314 are not symmetrically arranged.
In order to take into account the complexity and convenience of the structure, in an embodiment of the invention, the covering member 11 may include two regions that are different in the ease of being ruptured, which are respectively referred to as a first region and a second region for convenience of description, the first region being more easily ruptured relative to the second region, and the first region being a region suitable for rupturing by the rupturing element, i.e. a user may rupture the first region with the rupturing element so that the heating element may heat the aerosol-forming substrate, while at the same time the second region may remain unbroken.
In other words, the first region may be referred to as a breakable region and the second region may be referred to as a non-breakable region. The breakable region can be easily pierced or broken by the heating element of the aerosol-generating device without damaging the heating element, the breakable region is not pierced when it is pierced, and the breakable region is prevented from being torn. The frangible region may be weaker than the non-frangible region. The closure of the wrapping member 11 of the outer wall of the packaging structure 1 is not absolute and allows air to enter, which may allow for a smoother air path for the aerosol-generating article when it is being smoked, but the outer wall of the aerosol-generating article should not allow the aerosol-forming substrate to leak through the outer wall of the packaging structure 1 before and during use.
In one embodiment, the first region is rupturable by the rupturing element with a force below a predetermined first threshold, and the rupturing element is not damaged during the rupturing process, i.e., the user can puncture the first region with a small force, which does not damage the rupturing element, thereby improving the convenience of the aerosol-generating article.
Those skilled in the art may employ a variety of arrangements to impart different degrees of ease of fracture to the first and second regions.
For example, in terms of thickness, in an embodiment of the present invention, the first region and the second region are made of the same material, but the first region is thinner than the second region. For easy understanding, referring to fig. 4, the first region 412 and the second region 411 have the same thickness, but the strength of the material of the first region 412 is lower than that of the material of the second region 411.
For example, in another embodiment of the present invention, the first region and the second region have the same thickness in terms of strength, but the material strength of the first region is lower than the material strength of the second region. Referring to fig. 5, the first region 512 and the second region 512 are made of the same material, but the first region 511 is thinner than the second region 512.
For example, the first region and the second region are made of different materials, and the first region and the second region are different in thickness, but the balance between the materials and the thicknesses is still that the first region is more easily broken than the second region. For easy understanding, referring to fig. 6, the first region 612 and the second region 611 are made of different materials, and the first region 612 and the second region 611 have different thicknesses.
In addition, in the implementation, for various reasons such as cost, it is also possible to refer to fig. 7, and the first region 712 and the second region 711 are made of different materials, and the first region 712 and the second region 711 are different in thickness, so that although the material of the second region 711 is more easily broken, the balance between the material and the thickness is still that the first region 712 is more easily broken than the second region 711.
In particular implementations, one skilled in the art may also use structural arrangements to achieve that the first region is more easily ruptured than the second region. For example, in an embodiment of the invention, the first region is recessed deeper relative to the second region towards the location of the aerosol-forming substrate, the bottom end of the recessed surface is the first region, and the depth of the recess can be set by a person skilled in the art according to actual needs, for example, can be 2 mm.
The deeper depression in the embodiment of the present invention means that the first region is recessed more deeply into the position where the aerosol-forming substrate is disposed than the second region, that is, the first region is recessed inward of the wrapping member than the second region, when viewed from the outside of the packaging structure.
Thus, it is now easier for the user to perform the act of rupturing the first region and, as the first region is recessed deeper, may also serve as a guide for the user to rupture the first region for use of the aerosol-generating article, i.e. the end-recessed wrapper member may guide the aerosol-generating article to align the heating element with the first region more easily when the aerosol-generating article is inserted into the aerosol-generating device.
For the sake of understanding, fig. 8-14 show schematic diagrams of the covering members with various concave arrangements in the embodiment of the present invention, the area enclosed by the dotted circle represents the first area, and the second area is the area except the first area in the covering member 11, and the second area is not numbered due to the arrangement of the concave structure, so the second area is not numbered in the drawings. As shown in fig. 8, the first region 811 is recessed in an arc shape toward the inside of the sheathing member 11.
As shown in fig. 8, the first region 811 is recessed in an arc shape toward the inside of the sheathing member 11. As shown in fig. 9, the first region 911 is recessed in a funnel shape toward the inside of the covering member 11. As shown in fig. 10, the first region 1011 is recessed toward the inside of the covering member 11 in a normal circular arc shape. As shown in fig. 11, the first region 1111 is recessed in a funnel shape toward the inside of the covering member 11. As shown in fig. 12, the first region 1211 is recessed in a funnel shape toward the inside of the cover member 11. As shown in fig. 13, the first region 1311 is recessed in a funnel shape toward the inside of the cover member 11. As shown in fig. 14, the first region 1411 is recessed in a funnel shape toward the inside of the cover member 11. Therefore, the person skilled in the art can arrange the recessed structure according to actual needs.
In addition, in another embodiment of the present invention, the connection relationship between the first region and the peripheral region thereof may be weaker than the connection relationship between the second region and the peripheral region thereof in the configuration. Since the ease with which a region is broken is related to the closeness of the connection with the peripheral region, it is also easier for the user to break the first region that is less connected with the peripheral region. For example, the first region may be provided as a small opening to facilitate the opening through which the rupture element passes.
It is noted that the skilled person may set the parameters of the first region in correspondence with the properties of the rupture element, thereby improving the applicability of the aerosol-generating article. In particular, in embodiments, the shape of the first region may be related to the shape of the rupturing element, which is typically needle, cylinder, sword or blade shaped, so that the shape of the first region may be circular, oval, rectangular or other irregular shape, or may be a gap which is closed before the aerosol-forming substrate is used, or which is not large enough to allow the aerosol-forming substrate to fall therethrough, and which may itself be circular, oval, rectangular or other irregular shape.
The specification of the first region and the specification of the rupture element may be related to each other, and for example, the first region may be provided to have the same area as the cross-sectional area of the leading end of the rupture element. If a plurality of regions with different rupture difficulties are required, different positions of the different regions in the sheathing member may also be associated with the rupture element, for example if the rupture structure has two rupture surfaces, two portions that are relatively easily ruptured may be provided correspondingly, and further if the two rupture surfaces are structurally symmetrical, two portions that are relatively easily ruptured may also be provided symmetrically.
In a particular implementation, the broken outline of the first region after being pierced should more closely conform to a heating element that may heat the aerosol-forming substrate to facilitate scraping of the heating element as the aerosol-generating article leaves the aerosol-generating device, but the fit should not be too tight to affect the smoothness of the air path during use of the aerosol-generating article.
It should be noted that the person skilled in the art can arrange the first region at any position of the whole cladding member, and the arrangement of the position does not set any limit to the scope of protection of the present application. In an embodiment of the invention, the first region is arranged in the centre of the cover member, thereby providing more convenience for a user to use the aerosol-generating article.
For ease of understanding, fig. 15-25 show schematic end views of various cladding components in embodiments of the present invention, in which the solid lines in the end views represent cut-through end faces, the solid line geometry represents a hollow-out geometry in the middle, and the dashed lines represent half-cut-through, indicating that the region at the dashed lines is less connected to the peripheral region and is vulnerable to damage by the heating element. Referring to fig. 15, the first region 1511 is a slit, and the shape of the slit is circular. Referring to fig. 16, the first region 1611 is a slit, and the shape of the slit is an ellipse. Referring to fig. 17, the first region 1711 is a slit, and the shape of the slit is an ellipse. Referring to fig. 18, the first region 1811 is a slit.
Referring to fig. 19, the first area 1911 is half-cut connected to the second area 1912, the first area 1911 is relatively weaker in connection with the peripheral area, i.e., the second area 1912, and the first area 1911 is circular. Referring to fig. 20, the first area 2011 is half-cut through to the second area 2012, the connection between the first area 2011 and its peripheral area, i.e., the second area 2012, is weaker than the connection between the second area 2012 and other components of the cover member 11, and the first area 2011 is vertical. Referring to fig. 21, the first region 2111 is two intersecting slits. Referring to fig. 22, the first region 2211 is two crossed hollow slits, and each hollow slit is connected to the peripheral region, i.e., the second region 2012, relatively weakly. Referring to fig. 23, the first region 2311 is a hollow gap, and the center of the hollow gap is a hollow gap. Referring to fig. 24, the first region 2411 may be disposed at the upper left corner of the sheathing member 11. Referring to fig. 25, the first region 2511 may be disposed at a lower right corner of the cover member 11.
In order to improve the user experience, in specific implementation, a breakable identifier may be further disposed on the first area. It should be noted that, a person skilled in the art may set the identification information in various ways to guide the user, and in an embodiment of the present invention, different colors may be used to distinguish the first area from the second area, for example, the first area is black, and the second area is white. In another embodiment of the present invention, a breakable symbol may be disposed on the first area, and the breakable symbol may be a text or a special symbol. In another embodiment of the present invention, the first region and the second region may be distinguished by different colors, and at the same time, the easily breakable mark may be provided at the first region.
In a specific implementation, the covering member or the entire packaging structure 1 may be made of a material that is air-permeable and resistant to high temperature. The material is required to be non-combustible, non-ignitable, non-meltable, non-deformable and not significantly damaged at a temperature of at least 300 ℃. For example, paper materials made of wood pulp, straw pulp, hemp pulp, reed pulp, bamboo pulp and the like of different natural fibers can be adopted, and metal sheets made of metal such as aluminum and the like can also be adopted. Specifically, the covering member or the entire packaging structure may be made of one or a mixture of pulp material and aluminum foil. Besides, the paper pulp material has the advantages of less peculiar smell and higher safety compared with other materials, and besides the paper pulp material, the whole packaging structure or the coating component can also be made of other safe materials which do not deform after being heated. The pulp material may be formed into a packaging structure in a single step, for example, in a single step, or may be formed by splicing, for example, by forming a paper tube and then assembling paper sheets at one end of the paper tube to form a structure with one end closed or semi-closed, so as to partially or completely cover the end surface of the aerosol-forming substrate near the distal end.
To enable a person skilled in the art to better understand and implement the present invention, figure 26 shows a heated non-combustible aerosol-generating article in the practice of the invention, which may comprise the wrapper member 11 of the heated non-combustible aerosol-generating article of any of the embodiments described above, as can be seen with reference to figure 26.
Also, the heated non-combustible aerosol-generating article may comprise an aerosol-forming substrate 21 disposed upstream of the mouth end in the column or cartridge, a filter segment disposed between the aerosol-forming substrate 21 and the filter segment, and a cooling segment disposed within the packaging structure 1 proximate the mouth end 12. In addition to these features, decorative paper may be attached to the outside of the heated non-combustible aerosol-generating article and may also be wrapped with tipping paper specific to a cigarette to give the heated non-combustible aerosol-generating article an appearance that more closely resembles a conventional cigarette. Moreover, in order to improve the taste, a plurality of filtering sections can be arranged, and can be respectively arranged in the packaging structure 1 near the mouth end 12 and near the far end.
In a specific implementation, the total length of the cooling section and the filtering section is not less than 30mm, and if the total length is too short, the temperature reduction is easy to be insufficient, and the air containing the aerosol is overheated.
The cooling and filtering sections described above are a combined structure whose primary function is to filter part of and cool the air containing the aerosol, the function of the filtering also including blocking the aerosol-forming substrate 21 from moving towards the mouth end on draw. With continued reference to FIG. 26, the cooling and filter segments may include a solid plug 22, a hollow plug 24, and a cavity 23. Wherein: the cavity 23 may be of other temperature reducing material, with the solid plug 22 being disposed between the cavity 23 and the aerosol-forming substrate 21 and the hollow plug 24 being disposed between the cavity 23 and the mouth end 12. In practice, the filter and cooling sections may also have different combinations of cooling or filtering materials and the different combinations must be such that the air and aerosol-forming substrate 21 can pass through the filter section smoothly when heated, i.e. such that a person can draw the aerosol-generating article on a regular basis.
In order to subsequently cooperate with the heating element, the different forms of the combination must also be able to confine the aerosol-forming substrate 21 to a range that can be heated by the heating element, avoiding the aerosol-forming substrate 21 passing through the cooling and filtering sections into the mouth of the smoker, and therefore include at least one section of a solid filter rod or have a material or structure that blocks the passage of the aerosol-forming substrate 21. In an embodiment of the invention, this blocking member is preferably located at an end of the cooling section adjacent the aerosol-forming substrate 21.
The cooling section and the filter section may comprise at least one section with a barrier against the aerosol-forming substrate 21, and other sections may be selected according to the actual requirements. Generally, those skilled in the art may employ solid filter rods, hollow filter rods, cooling materials, cavities or paper tubes, and the like.
In particular embodiments, the solid filter plug 22 is a filter plug similar to a conventional cigarette, preferably a solid filter plug is used as a component for blocking the aerosol-forming substrate 21, or a multi-segment solid filter plug may be used; the solid filter rod 22 can entrap smoke, so the solid filter rod 22 with low entrapment efficiency is preferably selected, and the entrapment efficiency can be realized by controlling the denier of tows or the length of the solid filter rod 22. In order to avoid the solid filter rod 22 being too short, as the components are too small to facilitate the production operation during assembly of the aerosol-generating article, the solid filter rod 22 may preferably be at least 3mm in length.
The hollow filter rod 24 has a cavity 23 which has less influence on the passage of air containing the aerosol, has a better supporting effect and can assist in increasing the strength of the aerosol-generating article, and preferably the hollow filter rod 24 is placed on the mouth end side better. The hollow filter rod 24 should also not be too short, since the components are too small to facilitate the production operation during assembly of the aerosol-generating article, and preferably the hollow filter rod 24 is at least 3mm in length.
The temperature reducing material is a material having a certain heat absorbing capacity, and when air containing aerosol passes through the material, heat of the air containing aerosol is partially absorbed by the temperature reducing material, so that the temperature of the air containing aerosol is reduced. When the cooling material works, substances which are toxic and harmful to human bodies are generated, and the related limit requirements are met.
In specific implementation, the cavity 23 does not have a filtering effect, but the cavity 23 can extend the aerosol generating product, so as to extend the movement stroke of the air containing the aerosol, and play a role in cooling the air containing the aerosol, so that the temperature of the air containing the aerosol is not too high when the air enters the mouth of a person, thereby avoiding scalding, and the length of the cavity 23 can adjust the temperature of the air containing the aerosol, so as to influence the suction feeling. The cavity 23 may be formed directly by hollowing out a section of the packaging structure 1 without filling any parts, or by filling a section of paper tube in the packaging structure 1 in close proximity to the packaging structure 1, which paper tube may assist in increasing the strength of the overall aerosol-generating article.
In the specific implementation, the cooling section and the filtering section may be wrapped into a whole and then filled into the packaging structure 1, or several parts of the structures constituting the cooling section and the filtering section may be respectively filled into the packaging structure 1.
In a specific embodiment, the cooling section and the filter section may be fixed to the packaging structure 1 by means of an adhesive which is safe to heat and has no or little off-taste. The cooling section and the filtering section can also be fixed together with the packaging structure 1 by the tension of the cooling section and the filtering section, and the relative positions of the cooling section and the filtering section and the packaging structure 1 are kept unchanged in the using process.
To enable those skilled in the art to better understand and implement the present invention, embodiments of the present invention also provide a heated, non-combusting aerosol-generating system, which may include: a heated non-combustible aerosol-generating article of any of the embodiments described above, and an aerosol-generating device having a heating element, the aerosol-generating device comprising a rupturing element for rupturing a relatively weaker region of the cover member to allow air to be drawn through the aerosol-generating article when a smoker draws on the mouth end.
In a particular implementation, the rupturing element is a heating element arranged to be inserted into the distal end when the heated non-combustible aerosol-generating article is engaged with the aerosol-generating device to rupture a relatively weaker region of the cover member and heat the aerosol-forming substrate to form an aerosol.
In a specific implementation, in use, the aerosol-generating article is inserted into a non-combustible, heated aerosol-generating device, and when inserted, a heating element of the aerosol-generating device pierces an easily pierceable region of an outer wall of the aerosol-generating article, the heating element contacts with an aerosol-forming substrate, the aerosol-generating device is activated, the heating element generates heat, the aerosol-forming substrate is heated, and components such as nicotine, aroma substances, added essence, and smoke agent glycerin in the aerosol-forming substrate are released and pass through a cooling section and a filtering section in the aerosol-generating article in sequence, for example, pass through a solid filter stick, a cooling material, a cavity, and a hollow filter stick in sequence, and enter the mouth of a smoker. The particles of the aerosol-forming substrate do not enter the mouth of the smoker because of the obstruction of the solid filter rod. After the draw is complete, the aerosol-generating device is deactivated and the aerosol-generating article is withdrawn, and during withdrawal the pierceable region is pierced to form a profile which can scrape the heating element without leaving residual aerosol-forming substrate attached thereto.
Thus, embodiments of the invention may limit the egress of the aerosol-forming substrate from the aerosol-generating article prior to use, and may wipe the heating element with the edges of the regions that are pierceable and non-pierceable after use of the aerosol-generating article as the aerosol-generating article exits the heating element, by designing the structure of the outer wall of the packaging structure near one end of the aerosol-forming substrate as a wrapper component, so that the heating element is cleaner and less susceptible to re-use, and may also prevent the aerosol-forming substrate from falling into the aerosol-generating article or aerosol-generating device as the aerosol-generating article exits the heating element.
In a specific implementation, the material of the aerosol-forming substrate may comprise tobacco, which may be, for example, natural tobacco, homogenised, reconstituted tobacco, may be in the form of tobacco rod, flakes, powder or granules, and which may release volatile compounds to form an aerosol when heated.
In particular implementations, the term "upstream" is used to describe the relative position of an element or portion of an element of an aerosol-generating article with respect to the direction in which a user draws on the aerosol-generating article during use thereof, as will be appreciated by those skilled in the art.
In summary, the above-mentioned embodiments are provided only for illustrating the principles and effects of the present invention, and not for limiting the present invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
