DETAILED DESCRIPTION
[0016] 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".
[0017] 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.
[0018] 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.
[0019] 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.
[0020] 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.
[0021] In some embodiments, the delivery system is a non-combustible aerosol provision system,
such as a powered non-combustible aerosol provision system.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
