DETAILED DESCRIPTION
As used herein, the term "aerosol-generating material" is a material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosol-generating material may, for example, be in the form of a solid, liquid or gel which may or may not contain an active substance and/or flavourants. Aerosol-generating material may include any plant based material, such as tobacco-containing material and may, for example, include one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco or tobacco substitutes. Aerosol-generating material also may include other, non-tobacco, products, which, depending on the product, may or may not contain nicotine. Aerosol-generating material may for example be in the form of a solid, a liquid, a gel, a wax or the like. Aerosol-generating material may for example also be a combination or a blend of materials. Aerosol-generating material may also be known as "smokable material".
The aerosol-generating material may comprise a binder and an aerosol former. Optionally, an active and/or filler 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 from botanical material. In some embodiments, the aerosol-generating material is substantially tobacco free.
The aerosol-generating material may comprise or be an "amorphous solid". The amorphous solid may be a "monolithic solid". In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosol-generating material may, for example, comprise from about 50wt%, 60wt% or 70wt% of amorphous solid, to about 90wt%, 95wt% or 100wt% of amorphous solid.
The aerosol-generating material may comprise an aerosol-generating film. The aerosol-generating film may comprise or be a sheet, which may optionally be shredded to form a shredded sheet. The aerosol-generating sheet or shredded sheet may be substantially tobacco free.
According to the present disclosure, a "non-combustible" aerosol provision system is one where a constituent aerosol-generating material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery of at least one substance to a user.
In some embodiments, the delivery system is a non-combustible aerosol provision system, such as a powered non-combustible aerosol provision system.
In some embodiments, the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosol-generating material is not a requirement.
In some embodiments, the non-combustible aerosol provision system is an aerosol-generating material heating system, also known as a heat-not-burn system. An example of such a system is a tobacco heating system.
In some embodiments, the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosol-generating materials, one or a plurality of which may be heated. Each of the aerosol-generating materials may be, for example, in the form of a solid, liquid or gel and may or may not contain nicotine. In some embodiments, the hybrid system comprises a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may comprise, for example, tobacco or a non-tobacco product.
Typically, the non-combustible aerosol provision system may comprise a non-combustible aerosol provision device and a consumable for use with the non-combustible aerosol provision device.
In some embodiments, the disclosure relates to consumables comprising aerosol-generating material and configured to be used with non-combustible aerosol provision devices. These consumables are sometimes referred to as articles throughout the disclosure.
In some embodiments, the non-combustible aerosol provision system, such as a non-combustible aerosol provision device thereof, may comprise a power source and a controller. The power source may, for example, be an electric power source or an exothermic power source. In some embodiments, the exothermic power source comprises a carbon substrate which may be energised so as to distribute power in the form of heat to an aerosol-generating material or to a heat transfer material in proximity to the exothermic power source.
In some embodiments, the non-combustible aerosol provision system may comprise an area for receiving the consumable, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter and/or an aerosol-modifying agent.
In some embodiments, the consumable for use with the non-combustible aerosol provision device may comprise aerosol-generating material, an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generator, an aerosol generation area, a housing, a wrapper, a filter, a mouthpiece, and/or an aerosol-modifying agent.
An aerosol generating device can receive an article comprising aerosol generating material for heating. An "article" in this context is a component that includes or contains in use the aerosol generating material, which is heated to volatilise the aerosol generating material, and optionally other components in use. A user may insert the article into the aerosol generating device before it is heated to produce an aerosol, which the user subsequently inhales. The article may be, for example, of a predetermined or specific size that is configured to be placed within a heating chamber of the device which is sized to receive the article.
Figures 1A to 1C show perspective views of an aerosol provision device 10 in three different operational configurations, wherein an "operational configuration" may result from at least one of certain components of device 10 being operated by a user or an article being inserted into the device 10.
In Figures 1A to 1C, like reference numerals indicate the same, essentially the same, functionally identical, or similar components and will be described together hereinbelow. Repeated explanations are omitted for reasons of conciseness.
The aerosol provision device 10 is configured to generate aerosol from an aerosol generating article, which is not shown in Figures 1A and 1B and which is shown and referred to with reference numeral 20 in Figure 1C.
The aerosol provision device 10 is an elongate structure, extending along a longitudinal axis. The aerosol provision device 10 has a proximal end 10a, which will be closest to the user (e.g. the user's mouth) when in use by the user to inhale the aerosol generated by the aerosol provision device 10, as well as a distal end 10b which will be furthest from the user when in use. The proximal end 10a may also be referred to as the "mouth end" or "top end". As further explained below, the proximal end 10a of the aerosol provision device 10 is formed by a top unit, also referred to as an "extractor" 11.
The aerosol generating article 20 may be inserted, in use, into the aerosol provision device 10. For this purpose, the aerosol provision device 10 comprises an opening 14 to a receptacle discussed below, as shown in Figure 1B, into which the aerosol generating article 20 may be inserted, and which is provided as a heating chamber which is not fully shown for reasons of clarity. In certain embodiments, or the aerosol provision device 10 and the article 20 may be understood as parts of an aerosol generating system as referred to with reference numeral 100 in Figure 1C.
The aerosol provision device 10 also accordingly defines a proximal direction, which is directed towards the user when in use. Further, the aerosol provision device 10 also likewise defines a distal direction, which is directed away from the user when in use. The terms proximal and distal as applied to features of the device 10 will be described by reference to the relative positioning of such features with respect to each other in a proximal-distal direction along a longitudinal axis which is not shown for reasons of conciseness.
The aerosol provision device 10 includes a slidable lid unit 12. When the aerosol provision device 10 is not in use, the slidable lid unit 12 may be closed so as to cover the opening 14 to the receptacle of the aerosol provision device 10 as shown in Figure 1A. The slidable lid unit 12 may be held in certain positions by magnets associated with the lid unit 12 and/or a body of the device 10 beneath the lid unit 12. As shown in Figures 1B and 1C, the lid unit 12 may be opened to provide access to the opening 14 to the receptacle, and the extractor 11 comprises a generally flat base 13 extending in a plane.
One or more user-operable control elements 17, such as buttons, sliders or the like which can be used to operate the aerosol provision device 10, may be provided on a side of the aerosol provision device 10.
Figures 2A to 2F show desired and undesired positions of lid unit 12 in the aerosol provision device 10 shown in Figures 1A to 1C. More specifically, the extractor 11 already shown above is shown in each of Figures 2A to 2F in a state being removed from the rest of the elements of the aerosol provision device 10. As visible from Figures 2A to 2F, the receptacle mentioned above is formed by a peripheral wall and referred to with reference numeral 15. The receptacle 15 is an integral part of the extractor 11, into which an article 20 can be introduced to be heated. A cap part, also referred to as covering unit 16 at other places herein, is also part of the extractor 11, as well as further parts described below.
Figures 2A and 2D show desired positions of the lid unit 12 in an open state corresponding to Figure 1B (see Figure 2A) and a closed state corresponding to Figure 1A (see Figure 2D). In these desired positions, the lid unit 12, i.e. an upper surface thereof, is arranged essentially parallel to the upper surface of the extractor 11. In contrast, in Figures 2B, 2C, 2E and 2F show undesired positions in which the lid unit 12 is tilted. This is disadvantageous particularly because items, e.g., in a pocket of a user, such as keys, handkerchiefs, parts of a wallet or cloth may get under the lid, lift it up, and in a worst case tear it off.
Embodiments as disclosed herein solve these problems as indicated below by providing a guiding structure in which parts of the lid unit 12 may be lifted to avoid tilting as shown before.
Figures 3A to 3D show an extractor 11 as discussed before in an enlarged perspective view. More specifically, the extractor 11 is shown with the lid unit 12 in an open state corresponding to Figure 1B (see Figure 3A) and a closed state corresponding to Figure 1A (see Figure 3B). Figure 3C shows the extractor 11 with the lid unit 12 removed to expose the underlying components, i.e., a guiding arrangement configured to guide the lid unit 12 when slid between the positions shown in Figures 3A and 3B, which are referred to as a "first" and a "second" position herein, and in these positions.
As particularly seen in Figures 3B and 3C, the guiding arrangement includes the flat base 13 already shown in Figure 1A, which extends in a plane, and lifting structures in the form of protrusions 18 arranged at edges of the base 13 parallel to the sliding direction. Of the protrusions 18, only one protrusion 18 is visible in Figures 3B and 3C while the other is hidden by a rim of covering structure 16. The protrusions 18 protrude from the base 13 in the proximal direction according to the definition given above and are configured to lift a part of the lid unit 12 in the first position and in the second position. The lifting structures 18 are arranged at central sections of two edges of the base 13, as further illustrated and explained below.
Certain elements of extractor 11 are further illustrated below, and details and functions of certain parts are explained. As discussed, using the protrusions 18 already mentioned or additional or alternative protrusions form guiding structures configured to at least one of lift and depress at least a part of the lid unit 12 when the lid unit 12 is in the first position and in the second position or moved therebetween
In this connection, and for this purpose, Figure 4 shows an enlarged perspective view of a base subunit of the extractor 11 comprising the base 13 which was already shown before, Figure 5 shows an enlarged top view of a lid carrier sled 19 which may form part of the lid unit 12, Figure 6 shows an enlarged combined top view of the lid carrier sled 19 shown in Figure 5 and the base subunit shown in Figure 4, Figure 7 shows an enlarged combined top view of the lid carrier sled 19 shown in Figure 5, the base 13 of the lid guiding arrangement shown in Figure 4, and the covering unit 16 shown before, 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.
Figures 4 to 9 will be described together and the same reference numerals as above will be used further, wherein certain reference numerals will, for reasons of clarity, be used in certain Figures only without thereby indicating that corresponding elements are not present in the other Figures as well. It should be noted that the views of Figures 4 to 7 are from above, i.e. from a viewing point which would be at the top of Figures 1A to 1C, or "a user view" which a user would have from the device 10 when using the device 10, and the views of Figures 8 and 9 are from below, i.e. from a viewing point which would be at the bottom of Figures 1A to 1C, or a "device view" from the device towards the user of the device 10.
As can be seen from Figure 4, similarly to Figures 3A to 3C, the protrusions 18 protruding from the base 13 may be arranged at opposite edges 13a and 13b of the base 13 extending in parallel to a sliding direction of lid unit 12. The lid carrier sled 19 shown in Figure 5 in particular is configured to carry a sled cover which is exposed to a user, and may include structures configured to carry holding means such as magnets and the like. Skids 19a and 19b are part of the lid carrier sled 19 which are configured to mate with corresponding grooves formed between the base 13 and the covering unit 16 when they are brought into an operational configuration such as shown in Figures 7 and 8. As can clearly be seen from the Figures, the lid carrier sled 19, and therefore the lid unit 12 as a whole, is partly lifted when slid along the sliding direction between the first and second position, so that the unwanted tilting shown in Figures 2B, 2C, 2E and 2F is avoided.
As can be seen from Figures 8 and 9, the covering unit 16, on the other hand, may comprise depressing structures, i.e. protrusions 16a to 16d, which may be formed as integral parts of the covering unit 16, and which serve to depress a part of the lid unit 12 to closely attach to the base 13 in the first and second position.
Figures 10A to 10C show side views of certain elements of an aerosol provision device in a schematized manner, where the covering unit is partly illustrated and indicated, as above, with 16, and certain protrusions are indicated with 16a, 16b, and 18 as discussed in more detail in connection with the preceding Figures and one of the skids of the carrier sled 19 is indicated 19a.
As can be seen from Figures 10A and 10B, the protrusions 18 comprise sections 18a and 18b of opposite slopes, with or without an intermediate section 18c parallel to the plane of the base 13 or the lid unit 12. In an alternative configuration shown in Figure 10C, the protrusions 18 may be provided in a curved or straight shape in a sectional view orthogonal to the plane of the base 13.
As shown in Figures 10A to 10C, in other words, first protrusions in the form of protrusions 16a and 16b spaced apart by a protrusion distance are arranged at the covering unit 16 and second protrusions 18 comprising a maximum height at a position within the protrusion distance may be arranged at the base, and between these protrusions 16a, 16b and 18 the lid unit 12 or skids 19a are provided.
Figures 11A to 11C show side views of certain elements of an aerosol provision device in a schematized manner, similarly to the views shown in Figures 10A to 10C.
As shown in Figures 11A to 11C, the covering unit 16 is provided without protrusions, but the lid unit 12, or the skids 19a, are provided with such, as indicated with 12a and 12b. A similar effect as above can be provided in this way, which comprises that guiding structures are generated including the protrusions 12a, 12b and 18, which are configured to at least one of lift and depress at least a part of the lid unit 12 when the lid unit 12 is in the first position and in the second position and or moved therebetween.
Also Figures 12A to 12C show side views of certain elements of an aerosol provision device in a schematized manner, similarly to the views shown in Figures 10A to 10C and particularly Figures 11A to 11C.
As shown in Figures 12A to 12C, the covering unit 16 is, as before, provided without protrusions, but the lid unit 12, or the skids 19a, are provided with such, as indicated with 12c and 12c, but at opposite faces of the lid unit 12, or the skids 19a as compared to the configurations shown in Figures 11A to 11C. Again, a similar effect as above can be provided in this way, which was repeatedly explained above.
Figures 13A to 13C show side views of certain elements of an aerosol provision device in a schematized manner, similarly to the views shown in Figures 10A to 10C, more particularly Figures 11A to 11C, and specifically Figures 12A to 12C.
As shown in Figures 13A to 13C, the covering unit 16 is provided with protrusions which are, however, provided in a similar shape as discussed for protrusions 18 which are arranged at the base 13 according to the configurations shown in Figures 10A to 10C, 11A to 11C, and 12A to 12C. As to further details and effects, reference is made to the explanations above regarding Figures 10A to 10C, 11A to 11C, and 12A to 12C.
Further configurations are shown in Figures 14A to 14C, 15A to 15C, and 16A to 16C wherein essentially the same explanations as to the previous Figures 10A to 10C, 11A to 11C, 12A to 12C, and 13A to 13C, apply. Further explanations are omitted for reasons of conciseness.
Figures 17A and 17B show certain parts of the device 10 and the article 20 essentially shown in the previous Figures already in a drawn-apart view (Figure 17A) and in an assembled view (Figure 17B). The extractor 11, which is shown here again, forms part of a removal mechanism which is used to aid extraction of the article 20 by pulling the article off a heater 125, or, more specifically, a pin-shaped part 125a thereof in a reliable way. The pin-shaped element 125a protrudes from a main body of the device shown before into a chamber in which the receptacle 15 of the extractor 11 is received. The pin upstands in the extractor 11 through a hole in the base of the receptacle 15, as becomes clear in a synoptic view of Figures 17A and 17B.
