[0037] As used herein, the term "aerosol - generating material" is a material that is capable of generating an aerosol when heated, irradiated, or otherwise stimulated. The aerosol - generating material can be, for example, in the form of a solid, liquid, or gel, which may or may not contain active substances and / or flavorants. The aerosol - generating material can comprise any plant - based material, such as tobacco - containing materials and can, for example, comprise one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The aerosol - generating material can also comprise other non - tobacco products, depending on whether the product may or may not contain nicotine. The aerosol - generating material can be, for example, in the form of a solid, liquid, gel, wax, etc. The aerosol - generating material can also be, for example, a combination or blend of materials. The aerosol - generating material can also be referred to as "puffable material".
[0038] The aerosol - generating material can include a binder and an aerosol - forming agent. Optionally, active substances and / or fillers may also be present. Optionally, a solvent such as water is also present, and one or more other components of the aerosol - generating material may or may not be soluble in the solvent. In some embodiments, the aerosol - generating material is substantially free of plant material. In some embodiments, the aerosol - generating material is substantially free of tobacco.
[0039] The aerosol - generating material can include an "amorphous solid" or can be an amorphous solid. The amorphous solid can be a "monolithic solid". In some embodiments, the amorphous solid can be a dry gel. An amorphous solid is a solid material in which some fluid (such as a liquid) can be retained. In some embodiments, the aerosol - generating material can, for example, include from about 50 wt%, 60 wt%, or 70 wt% of amorphous solid to about 90 wt%, 95 wt%, or 100 wt% of amorphous solid.
[0040] The aerosol - generating material can include an aerosol - generating film. The aerosol - generating film can include a sheet or can be a sheet, which can optionally be shredded to form shredded sheets. The aerosol - generating sheet or shredded sheets can be substantially free of tobacco.
[0041] According to the present disclosure, a "non - combustible" aerosol supply system is an aerosol supply system in which the aerosol - generating material that constitutes the aerosol supply system (or its components) does not ignite or burn in order to deliver at least one substance to the user.
[0042] In some embodiments, the delivery system is a non - combustible aerosol supply system, such as an electric non - combustible aerosol supply system.
[0043] In some embodiments, the non-flammable aerosol supply system is an electronic cigarette, also known as an e-cigarette device or an electronic nicotine delivery system (ENDS), but it should be noted that the presence of nicotine in the aerosol-forming material is not necessary.
[0044] In some embodiments, the non-flammable aerosol supply system is an aerosol-forming material heating system, also known as a heat-not-burn system. An example of such a system is a tobacco heating system.
[0045] In some embodiments, the non-flammable aerosol supply system is a hybrid system that uses a combination of aerosol-forming materials to produce an aerosol, and one or more of these aerosol-forming materials can be heated. Each of the aerosol-forming materials can be in the form of, for example, a solid, a liquid, or a gel, and can contain or can not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-forming material and a solid aerosol-forming material. The solid aerosol-forming material can include, for example, tobacco or non-tobacco products.
[0046] Typically, the non-flammable aerosol supply system can include a non-flammable aerosol supply device and a consumable used with the non-flammable aerosol supply device.
[0047] In some embodiments, the present disclosure relates to a consumable that includes an aerosol-forming material and is configured to be used with a non-flammable aerosol supply device. These consumables are sometimes referred to as articles throughout the present disclosure.
[0048] In some embodiments, the non-flammable aerosol supply system (such as its non-flammable aerosol supply device) can include a power source and a controller. The power source can be, for example, an electrical power source or an exothermic power source. In some embodiments, the exothermic power source includes a carbon matrix that can be energized to distribute power in the form of heat to the aerosol-forming material or a heat transfer material near the exothermic power source.
[0049] In some embodiments, the non-flammable aerosol supply system can include an area for receiving a consumable, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.
[0050] In some embodiments, a consumable used with the non-flammable aerosol supply device can include an aerosol-forming material, an aerosol-forming material storage area, an aerosol-forming material transfer component, an aerosol generator, an aerosol generation area, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.
[0051] An aerosol generating device can receive an article comprising an aerosol generating material for heating. In this context, an "article" is a component that contains or holds an aerosol generating material in use and is heated in use to volatilize the aerosol generating material and optionally other components. A user can insert the article into the aerosol generating device, after which the article is heated to produce an aerosol that the user then inhales. The article can, for example, have a predetermined or specific size configured to be placed within a heating chamber of the device, the size of the heating chamber being designed to receive the article.
[0052] Figures 1A to 1C A perspective view of an aerosol supply device 10 in three different operating configurations is shown, where an "operating configuration" can occur because of a user operating at least one of certain components of the device 10 or inserting an article into the device 10.
[0053] In Figures 1A to 1C the same reference numerals indicate identical, substantially identical, functionally equivalent or similar components and will be described together hereinafter. For the sake of brevity, repeated explanations are omitted.
[0054] The aerosol supply device 10 is configured to generate an aerosol from an aerosol generating article, which is not shown in Figure 1A and Figure 1B and is shown in Figure 1C and referred to by the reference numeral 20.
[0055] The aerosol supply device 10 is an elongated structure extending along a longitudinal axis. The aerosol supply device 10 has a proximal end 10a and a distal end 10b, the proximal end being closest to the user (e.g., the user's mouth) when the user uses it to inhale the aerosol generated by the aerosol supply device 10, and the distal end being farthest from the user in use. The proximal end 10a can also be referred to as the "mouth end" or "tip end". As further explained below, the proximal end 10a of the aerosol supply device 10 is formed by a top unit, which is also referred to as the "drawer" 11.
[0056] The aerosol generating article 20 can be inserted into the aerosol supply device 10 in use. For this purpose, the aerosol supply device 10 includes an opening 14 that leads to a receiving portion discussed below, as Figure 1B shown, into which the aerosol generating article 20 can be inserted, and the receiving portion is provided as a heating chamber, which is not fully shown for clarity. In some embodiments, the aerosol supply device 10 and the article 20 can be understood as part of an aerosol generating system (referred to by the reference numeral 100 in Figure 1C ).
[0057] The aerosol supply device 10 also correspondingly defines a proximal direction which, in use, points towards the user. Further, the aerosol supply device 10 also defines a distal direction which, in use, points away from the user. The terms "proximal" and "distal" applied to the features of the device 10 will be described by reference to the relative positioning of these features relative to each other in the proximal-distal direction along a longitudinal axis, which is not shown for the sake of brevity.
[0058] The aerosol supply device 10 includes a slidable cover unit 12. When the aerosol supply device 10 is not in use, the slidable cover unit 12 can be closed to cover the opening 14 leading to the receiving portion of the aerosol supply device 10, as Figure 1A shown. The slidable cover unit 12 can be held in certain positions by magnets associated with the cover unit 12 and / or with the body of the device 10 below the cover unit 12. As Figure 1B and Figure 1C shown, the cover unit 12 can be opened to allow access to the opening 14 leading to the receiving portion, and the extractor 11 includes a generally flat base 13 that extends in a plane.
[0059] One or more user-operable control elements 17 (such as buttons, sliders, etc.) that can be used to operate the aerosol supply device 10 can be provided on one side of the aerosol supply device 10.
[0060] Figures 2A to 2F Illustrated Figures 1A to 1C are the desired and undesired positions of the cover unit 12 in the aerosol supply device 10 shown. More specifically, the extractor 11 shown above is shown in each of Figures 2A to 2F in a state removed from the remaining elements of the aerosol supply device 10. As can be seen from Figures 2A to 2F , the above-mentioned receiving portion is formed by an outer peripheral wall and is denoted by the reference numeral 15. The receiving portion 15 is an integral part of the extractor 11 into which the article 20 can be introduced for heating. The cap portion (also referred to as the covering unit 16 elsewhere in this text) is also part of the extractor 11, as are the other parts described below.
[0061] Figure 2A and Figure 2D illustrate the cover unit 12 in the open state corresponding to Figure 1B (see Figure 2A ) and the closed state corresponding to Figure 1A (see Figure 2D ) of the desired positions. In these desired positions, the cover unit 12 (i.e., the upper surface of the cover unit) is arranged to be substantially parallel to the upper surface of the extractor 11. In contrast, in Figure 2B , Figure 2C ,Figure 2E and Figure 2F shows an undesirable position in which the lid unit 12 is tilted. This is disadvantageous, especially since, for example, items in the user's pocket (such as keys, handkerchiefs, part of a wallet or cloth) may be under the lid, lift the lid, and in the worst case tear off the lid.
[0062] The embodiments disclosed herein solve these problems as shown below by providing a guiding structure in which a part of the lid unit 12 can be lifted to avoid tilting (as shown previously).
[0063] Figures 3A to 3C The extractor 11 as discussed previously is shown in an enlarged perspective view. More specifically, the extractor 11 is shown with the lid unit 12 in a position corresponding to Figure 1B the open state (see Figure 3A ) and a position corresponding to Figure 1A the closed state (see Figure 3B ). Figure 3C The extractor 11 is shown with the lid unit 12 removed to expose the underlying components, namely the guiding arrangement, which is configured to guide the lid unit 12 when it slides between the positions shown in Figure 3A and Figure 3B and when it is in these positions, which are referred to herein as the "first" and "second" positions.
[0064] As can be seen especially in Figure 3B and Figure 3C , the guiding arrangement includes the flat base 13 extending in a plane as already shown in Figure 1A , and a lifting structure in the form of a projection 18, the projection being arranged at an edge of the base 13 parallel to the sliding direction. In the projection 18, only one projection 18 is visible in Figure 3B and Figure 3C , while the other projection is hidden by an edge of the covering structure 16. The projection 18 projects from the base 13 in the proximal direction according to the definition given above, and is configured to lift a part of the lid unit 12 in the first and second positions. The lifting structure 18 is arranged at the central section of the two edges of the base 13, as shown and explained further below.
[0065] Certain elements of the extractor 11 are shown further below, and the details and functions of certain parts are explained. As discussed, the guiding structure is formed using the projection 18 already mentioned or additional or alternative projections, which is configured to perform at least one of lifting at least a part of the lid unit 12 and pressing down at least a part of the lid unit 12 when the lid unit 12 is in the first position, in the second position, or moving between the first and second positions.
[0066] In this regard and for this purpose, Figure 4 shows an enlarged perspective view of the base subunit of the extractor 11 including the base 13 shown previously, Figure 5 shows an enlarged top view of the cover carrier slide 19 which can form part of the cover unit 12, Figure 6 shows Figure 5 the cover carrier slide 19 shown Figure 4 and an enlarged combined top view of the base subunit shown, Figure 7 shows Figure 5 the cover carrier slide 19 shown, Figure 4 the base 13 of the cover guiding arrangement shown, and an enlarged combined top view of the covering unit 16 shown previously, Figure 8 shows an enlarged bottom view of the covering unit 16, and Figure 9 shows an enlarged perspective view of the covering unit 16.
[0067] will be described together Figures 4 to 9 and will further use the same reference numerals as above, where, for clarity, some reference numerals will be used only in certain figures, but this does not mean that the corresponding elements do not exist in other figures either. It should be noted that Figures 4 to 7 the views of Figures 1A to 1C are from above, i.e., from the viewing point at the top of Figure 8 and Figure 9 the views of Figures 1A to 1C are from below, i.e., from the viewing point at the bottom of
[0068] As can be seen from Figure 4 and similar to Figures 3A to 3C , the protrusions 18 protruding from the base 13 can be arranged at the opposite edges 13a and 13b of the base 13 extending parallel to the sliding direction of the cover unit 12. Figure 5 The cover carrier slide 19 shown is specifically configured to carry the slide cover exposed to the user and may include a structure configured to carry holding means such as magnets. The slideways 19a and 19b are part of the cover carrier slide 19, and the slideways are configured to cooperate with corresponding grooves formed between the base and the cover unit when the base 13 and the covering unit 16 assume an operating configuration such as Figure 7 and Figure 8 shown. As can be clearly seen from the figure, the cover carrier slide 19 and thus the cover unit 12 are partially lifted as a whole when sliding between the first position and the second position along the sliding direction, thus avoiding Figure 2B , Figure 2C , Figure 2Eand Figure 2F the unwanted tilt shown in
[0069] As can be seen from Figure 8 and Figure 9 On the other hand, the covering unit 16 may include a pressing-down structure, i.e., protrusions 16a to 16d, which may be formed as an integral part of the covering unit 16 and are used to press down a part of the lid unit 12 at the first position and the second position to closely attach to the base 13.
[0070] Figures 10A to 10C A side view schematically shows some elements of the aerosol supply device, wherein the covering unit is partially shown and indicated by 16 as described above, and some protrusions are indicated by 16a, 16b and 18. As discussed in more detail in connection with the foregoing figures, one of the slides of the carrier slide 19 is indicated by 19a.
[0071] As can be seen from Figure 10A and Figure 10B it can be seen that the protrusion 18 includes sections 18a and 18b having opposing inclined surfaces, with or without an intermediate section 18c parallel to the plane of the base 13 or the lid unit 12. In Figure 10C the alternative configuration shown, the protrusion 18 may be provided in a curved or straight shape in a cross-sectional view orthogonal to the plane of the base 13.
[0072] As Figures 10A to 10C shown, in other words, a first protrusion arrangement in the form of protrusions 16a and 16b spaced apart by a protrusion distance is provided at the covering unit 16, and a second protrusion 18 having a maximum height may be arranged at the base at a position within the protrusion distance, and the lid unit 12 or the slide 19a is arranged between these protrusions 16a, 16b and 18.
[0073] Figures 11A to 11C A side view schematically shows some elements of the aerosol supply device, similar to Figures 10A to 10C the view shown in
[0074] As Figures 11A to 11C shown, the covering unit 16 is not provided with protrusions, but the lid unit 12 or the slide 19a is provided with protrusions, as indicated by 12a and 12b. In this way, an effect similar to the above can be provided, which includes generating a guiding structure including protrusions 12a, 12b and 18, which is configured to perform at least one of lifting at least a part of the lid unit 12 and pressing down at least a part of the lid unit 12 when the lid unit 12 is in the first position, in the second position and / or moving between the first position and the second position.
[0075] In addition, Figures 12A to 12CA side view of certain elements of the aerosol supply device is shown schematically, similar to Figures 10A to 10C and in particular Figures 11A to 11C the view shown.
[0076] As Figures 12A to 12C shown, the covering unit 16 is not provided with protrusions as before, but the lid unit 12 or the slide 19a is provided with protrusions, as indicated by 12c and 12d, but compared with Figures 11A to 11C the configuration shown, the protrusions are provided at the opposite faces of the lid unit 12 or the slide 19a. Similarly, an effect similar to the above can be provided in this way, which has been repeatedly explained above.
[0077] Figures 13A to 13C A side view of certain elements of the aerosol supply device is shown schematically, similar to Figures 10A to 10C , more particularly Figures 11A to 11C , especially Figures 12A to 12C the view shown.
[0078] As Figures 13A to 13C shown, the covering unit 16 is provided with protrusions. However, the protrusions are arranged in a shape similar to the shape of the protrusions 18 provided at the base 13 according to Figures 10A to 10C , Figures 11A to 11C and Figures 12A to 12C shown. For further details and effects, reference is made to the explanations above regarding Figures 10A to 10C , Figures 11A to 11C and Figures 12A to 12C .
[0079] Figures 14A to 14C , Figures 15A to 15C and Figures 16A to 16C show further configurations, to which the explanations substantially the same as those for the previous Figures 10A to 10C , Figures 11A to 11C , Figures 12A to 12C and Figures 13A to 13C apply. For the sake of brevity, further explanations are omitted.
[0080] Figure 17A and Figure 17B are shown in a separated view ( Figure 17A ) and an assembled view ( Figure 17B)Shows certain parts of the device 10 and the article 20, which parts have essentially been shown in the previous figures. The extractor 11, shown again here, forms part of a removal mechanism that serves to assist in extracting the article 20 by pulling the article from the heater 125, or more specifically from the pin-shaped portion 125a of the heater, in a reliable manner. The pin-shaped element 125a projects from the body of the device shown previously into the chamber of the receiving portion 15 that receives the extractor 11. The pin stands in the extractor 11 passing through a hole in the base of the receiving portion 15, as becomes clear in the Figure 17A and Figure 17B schematic views.
