Technical Field

The present invention relates to a receptacle section, and more particularly to a receptacle section for an aerosol provision article.

Background

Smoking articles such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternatives to these articles that burn tobacco by creating products that release compounds without burning.

Examples of such products are heating devices which release compounds by heating, but not burning, the material. The material may be for example tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol provision articles such as so-called e-cigarette devices. These devices typically contain a liquid which is heated to vaporise the liquid to produce an inhalable vapour or aerosol. The liquid may contain nicotine and/or flavourings and/or aerosol- generating substances, such as glycerol. The known e-cigarette devices typically do not contain flavourings other than those in the liquid.

Detailed Description

Referring to Figure 1, a schematic of an example aerosol provision article 100 is illustrated. The aerosol provision article 100 is an inhalation device (i.e. a user uses it to inhale an aerosol provided by the device). The aerosol provision article is handheld. In this example, the article 100 is an electronic cigarette device 100. In broad outline, the device 100 volatilises a liquid to form a vapour or an aerosol which passes through an activatable element 124 received in a receptacle section 102 of the device 100. In this example the receptacle section 102 is a mouthpiece of the device 102. The activatable element 124, once activated, modifies a property of the vapour or aerosol passing through the mouthpiece 102 for inhalation by a user. For example, the activatable element 124 may be a breakable flavour element 124 which, once broken, imparts a flavour to the vapour or aerosol passing through the mouthpiece 102 for inhalation by a user.

In this respect, first it may be noted that, in general, a vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that for example the vapour can be condensed to a liquid by increasing its pressure without reducing the temperature. On the other hand, in general, an aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas. A colloid is a substance in which microscopically dispersed insoluble particles are suspended throughout another substance. Returning to Figure 1, the device 100 comprises an outer body 106 housing a liquid container 122 containing liquid 116, an atomiser 108, and a battery portion 112. The atomiser 108 is (electrically) connected to the battery portion 112. The mouthpiece 102, in this example, is removably connected to the outer body 106. The mouthpiece 102 may be removed from the outer body 106, for example to allow access to the liquid container 122, for example to refill the liquid 116 held in the liquid container 122. The mouthpiece 102 has a channel 132 running there through that defines a flow path for a flow of vapour or aerosol. The mouthpiece 102 has removably received in the channel 132 a breakable flavour element 124 for imparting, once broken, a flavour to said flow of aerosol or vapour that passes through the mouthpiece 102 in use.

The breakable flavour element 124 may comprise flavoured materials that, once the breakable flavour element is broken (e.g. crushed, pierced mechanically activated), may be used to create a desired taste or aroma, or other properties, such as nicotine content. In this example, the breakable flavour element 124 comprises a breakable flavour capsule 126 for releasing, when broken for example by a user, a flavourant such as a liquid and/or a gel for imparting a flavour to a flow of at least one of a vapour and an aerosol. In this example, the breakable flavour element 124 comprises a breakable favour capsule 126 wrapped or embedded in a carrier material. The carrier material may comprise a material that allows vapour or aerosol to pass there through. The carrier material may comprise a material that holds the liquid and/or gel released from the breakable flavour capsule 126 when it is broken. The carrier material may be any suitable material, for example, cellulose acetate. When the breakable flavour element 124, and hence the flavour capsule 126, is broken (e.g. crushed, pierced, mechanically activated), the flavourant such as a liquid and/or gel contained in the flavour capsule 126 is released into the carrier material so as to flavour vapour or aerosol passing there through.

The breakable flavour element 124 may be porous, for example so as allow vapour or aerosol to pass through it. The breakable flavour element 124 may be self- supporting, so as to be easily handled by a user (for example easily inserted and/or removed from the mouthpiece 102). For example the breakable flavour element 124 may comprise material wrapped partially or wholly in a wrapper, and/or the breakable flavour element 124 may be supported in a resilient housing, for example a plastic housing (not shown). As mentioned above, the breakable flavour element 124 may comprise, for example, a carrier material, such as cellulose acetate or the like. This carrier material may itself be flavoured. The breakable flavour element 124 may be cylindrical, and/or comprise a cylindrical portion, so as to fit easily and/or tightly into a corresponding cylindrical channel 132 of the mouthpiece 102.

The device 100 is arranged so that, in use, as the liquid 116 is volatilised so as to produce an aerosol of liquid droplets or sufficiently heated to produce a vapour, at least some and preferably all or substantially all of the aerosol or vapour passes through the breakable flavour element 124 received in the mouthpiece 102 for example so as to entrain constituents of the flavour element 134 therein. In some examples, a vapour is produced that then at least partly condenses to form on aerosol before exiting the device 100.

The liquid container 122 is provided generally centrally of the outer body 106. The liquid container 122 is annular in shape and defines a channel 104 running through the length of the liquid container 122. The liquid container 122 may be formed of rigid, watertight and airtight materials, such as metal, suitable plastics, etc. It will be appreciated that the liquid container 122 may have a different shape, such as conical, frustroconical, or combination of these, etc.

The atomiser 108 is provided with a heater 110 and a wick (not shown) in (thermal) contact with the heater 110. The orientation of the heater 110 is shown schematically and for example the heater 110 may be a coil having its longitudinal axis perpendicular or parallel to the longitudinal axis of the liquid container 108. The wick (not shown) is in contact with the liquid 116. This may be achieved by for example by the wick (not shown) being inserted through a through hole (not shown) in an end wall 122b of the liquid container 122. Alternatively or additionally, the end wall 122b may be a porous member which allows liquid to pass through from the liquid container 122, and the wick (not shown) may be in contact with the porous end wall 122b. The end wall 122b may be for example in the form of a porous ceramic disk. A porous end wall 122b of this type helps to regulate the flow of liquid onto the wick (not shown). The wick (not shown) is generally absorbent and acts to draw in liquid 116 from the liquid container 122 by capillary action (shown in Fig. 1 by arrows A). The wick is preferably non- woven and may be for example a cotton or wool material or the like, or a synthetic material, including for example polyester, nylon, viscose, polypropylene or the like, or a ceramic material.

The atomiser 108 is (electrically) connected to a battery in the battery portion 116 to enable the heater 110 to be powered. When the heater 110 is powered (which may be instigated for example by the user operating a button (not shown) of the device 100 or by a puff detector (not shown) of the overall device 100, as is known per se, liquid 116 is drawn (shown in Figure 1 by arrows A) in from the liquid container 122 by the wick and is heated by the heater 110 to volatilise or vaporise the liquid, so as to generate at least one of a vapour and an aerosol.

As the user draws on the mouthpiece 102, air is drawn through an air inlet 118. The liquid 116 is volatised or vaporised by the heater 110 into air from the air inlet 118 thereby to produce a flow of one of a vapour and an aerosol. The flow of vapour or aerosol is drawn through the channel 104 of the liquid container 122, into the channel 132 of the mouthpiece 102, through the flavour element 134 received in the mouthpiece 102, and out from the device 100 for inhalation by a user (shown by arrow B in Fig. 1). The vapour or aerosol picks up (entrains) flavour (and/or other constituents) from the breakable flavour element 124 (for example once the breakable flavour element 124 is broken). One or more constituents of the breakable flavour element 124 is thereby mixed with the flow of at least one of a vapour and an aerosol. In examples where the breakable flavour element 124 contains or includes nicotine, the vapour or aerosol may thereby also contain nicotine entrained from the breakable flavour element 124. A one way valve (not shown) may be provided, for example at or near an upper end 122a of the liquid container 122, so that the vapour or aerosol can only exit the channel 104 and cannot back-flow to the heater 110 or the electronics (not shown) of the device 100. The breakable flavour element 124 may be or comprise material that may be used to impart a flavour (and/or one or more other constituents) to the aerosol or vapour. In some examples, the one or more constituents of the breakable flavour element 124 may comprise constituents inherent to the material itself. The material may for example consist of or comprise tobacco. As the aerosol or vapour passes through and over the tobacco, the aerosol or vapour entrains organic and other compounds or constituents from the tobacco that lend tobacco its organoleptic properties, thus imparting the flavour to the aerosol or vapour. It will be understood however that materials other than tobacco may be used to impart different flavours (and/or one or more other constituents) to the aerosol or vapour flow. The flavour element 124 may comprise constituents added to a material of the flavour element 124.

Nicotine may be provided in the liquid 116. Accordingly, where it is intended that the device 100 provides nicotine for the user, the nicotine may be provided in the liquid 116, may be obtained from the flavour element 124, or any combination of these. Likewise, flavourings may be added to the flavour element 124 (whether or not the flavour element 124 is or includes tobacco) and/or to the liquid 116. A material of the flavour element 124 may be a solid material, or be a mixture of solid materials, one or more of each comprising one or more constituents that can be mixed with the flow of vapour or aerosol. It will be appreciated that the flavour element 124 may comprise one or more other constituents that are not entrained into the aerosol or vapour passing there through. It will also be appreciated that the flavour element 124 may comprise a portion that does not impart any flavour and/or release any constituents into the flow of a vapour or an aerosol.

Various receptacle sections for use with an aerosol provision article (e.g. device 100 in Figure 1) will now be described. In broad overview, the various receptacle sections are arranged for receiving therein a breakable flavour element for releasing, once broken, a flavourant for imparting flavour to a flow of at least one of a vapour and an aerosol generated by an overall aerosol provision article in use. For example, the flavour may be imparted by the flow of at least one of an aerosol or vapour passing through the breakable flavour element installed in the receptacle section in use. The various receptacle sections each comprise at least one breaking element operable to break, after an installation of the breakable flavour element in the receptacle section by a user, the breakable flavour element installed in the receptacle section in use. The various receptacle sections therefore provide a convenient way for a user to break a breakable flavour element after the breakable flavour element has been installed in an overall aerosol provision article (e.g. device 100 in Figure 1) with which the receptacle section is being used. This allows, for example, a user to quickly and easily control, for example during use, whether the vapour or aerosol for inhalation is not flavoured by a flavour of the breakable flavour element (i.e. when the breakable flavour element is in a non-broken state), or whether the vapour or aerosol for inhalation is flavoured by a flavour of the breakable flavour element (i.e. when the breakable flavour element is in a broken (activated) state).

For reasons of convenience, as used herein the term aerosol should be taken as encompassing an aerosol, a vapour or a mixture of an aerosol and vapour.

Turning first to Figure 2, there is illustrated schematically a perspective view of a part of a device 200 that comprises an example receptacle section 202. In this example, the receptacle section 202 is a mouth-end section 202 of the device 200, that is, the receptacle section 202 is located toward an end of the device 200 for receipt into a user' s mouth in use. In some examples, the mouth-end section 202, or at least a portion thereof, is a mouthpiece 202. In other examples, the receptacle section 202 may at a different location in the overall device 200, for example intermediate of the body and the mouthpiece. For brevity, features in Fig. 2 and the functioning thereof that are the same or similar to those features already described with reference to Figure 1 are given similar reference numerals to as in Figure 1 but increased by 100, and will not be described in detail again.

The mouth-end section 202 is generally cylindrical in shape. The mouth-end section 202 is removably connected to a body 206 of the overall device 200, via a connecting means 228. The connecting means 228 may be, for example, a threaded connection or the like, for example the mouth-end section 202 may have a male thread connectable to a corresponding female thread of the body 206. The mouth-end section 202 comprises a removable mouth portion 202a for receipt into a user's mouth (not shown). The mouth-end section 202 defines a channel 232 internal thereof. The channel 232 extends from an opening (not shown in Figure 2) for fluid connection with an aerosol flow path 204 of the overall device (e.g. device 100 of Figure 1) to an opening 234 of the mouth portion 202a for outlet of aerosol for inhalation by a user. A breakable flavour element 224, comprising a breakable flavour capsule 226, is received in the channel 232. The mouth-end section comprises a breaking element 250. In this example, only one breaking element 250 is shown in Figure 2, but it will be appreciated that more than one breaking elements may be used, for example, any number of breaking elements. The breaking element 250 is moveable between a first position (as illustrated in Figure 2) and a second position. The first position is for allowing installation of the breakable flavour element 224 in the mouth-end section 202 by a user. For example, when the breaking element 250 is in the first position (as illustrated in Figure 2), the breaking element 250 does not extend into the channel 232, and hence the channel 232 is clear for installation of a breakable flavour element 234 therein, for example via the opening 234 of the mouth portion 202a. The second position (not shown) is for breaking the flavour element 234 installed in the mouth-end section 202 in use. Movement (arrow C) of the breaking element 250 from the first position to the second position breaks the breakable favour element 234 installed in the mouth-end section 202 in use.

Specifically, the movement of the breaking element 250 comprises movement of the breaking element 250 along an axis substantially perpendicular to a longitudinal axis P-P of the mouth-end section 202. In this example, the breaking element 250 is an elongate rod. The mouth-end section 202 defines an opening 231 in a side wall 230 of the mouth-end section 202 that extends from an outer surface of the mouth-end section 202 to the channel 232 defined by the mouth-end section 202. The breaking element 250 is received in the opening 231 of the side wall 230, and thereby slidably mounted through the side wall 230 of the mouth-end section 202. The breaking element 250 is longer than the side wall 230 is thick, and hence in the first position (as shown in Figure 2) protrudes out of the opening 231 away from the channel 232. The breaking element 250 is operable by a user to slide (arrow C) between the first position (as shown in Figure 2) and the second position (not shown), i.e. to slide through the side wall 230 and into the channel 232. In the second position the breaking element 250 extends into the channel 232 thereby to break the breakable flavour element 224 received in the channel 232 in use. The breaking element 250 breaks the breakable flavour element 250 laterally.

The breaking element 250 narrows at one end 250a for breaking the breakable flavour element 224. The narrowing at the end 250a of the breaking element 250 increases the pressure exerted on the breakable flavour element 224 by the breaking element 250 for a given force applied by a user. This increases the ease with which a user may break the breakable flavour element 224. In use, for example when the mouth-end section 202 is connected to the rest of the device (e.g. as shown schematically for device 100 in Fig. 1), a user may install a breakable flavour element 224 into the mouth-end section 202. At some later time, user may then operate the breaking element 250 to break the breakable flavour element 224. When a user draws on the mouth-end section 202, air is drawn in through an air inlet (120 in Fig. 1), and a heater (110 in Fig. 1) volatises liquid (116 in Fig. 1) held in the liquid container (122 in Fig. 1) into the inlet air to generate a flow of aerosol. The flow passes through the channel (104 in Fig. 1) in the liquid container (122 in Fig. 1), into the channel 232 of the mouth-end section 202, through the (broken) breakable flavour element 234, and exits from the outlet 234 of the mouth portion 202a for inhalation by the user. The flow of aerosol through the (broken) breakable flavour element 234 thereby entrains one or more of the constituents released by the broken flavour element 234 in the flow. This use description is applicable also to the other examples described herein, and so will not be described in detail again. Referring now to Figures 3a and 3b, there is illustrated schematically cross sections of another part of an aerosol provision device 300 comprising an example receptacle section 302 in different configurations. The cross sections in Figures 3a and 3b are taken in a plane perpendicular to the longitudinal axis P of the receptacle section 302. In this example, the receptacle section 302 is again a mouth-end section 302. For brevity, features in Figure 3 and the functioning thereof that are the same or similar to those features already described with reference to Figure 2 are given similar reference numerals to as in Figure 2 but increased by 100, and will not be described in detail again.

The mouth-end section 302 illustrated in Figures 3a to 3c is similar to the mouth- end section 202 illustrated in Figure 2. A breakable flavour element 324 comprising a breakable flavour capsule 326 is received in a channel 322 of the mouth-end section 302. A first breaking element 350 that narrows at one end 350a is received through an opening 331 in a side wall 330 of the mouth-end section 302, and is thereby operable between first and second positions as described above with respect to the breaking element 250 described above with reference to Figure 2 .

However, the mouth-end section 302 illustrated in Figures 3a to 3c comprises a second breaking element 351. The second breaking element 351 is essentially the same as the first breaking element 350. The second breaking element 351 is an elongate rod that narrows at one end 351a, and is received through a second opening 333 in the side wall 330 of the mouth-end section 302 thereby to be slidably mounted through the side wall 330 of the mouth-end section 302. Similarly to the first breaking element 350, the second breaking element 351 is operable by a user to slide between a first position (as in Figure 3a) in which the breaking element 351 does not extend into the channel 332, and a second position (as in Figure 3b) in which it does.

In this example, both the first breaking element 350 and the second breaking element 351 are arrow like in cross section. Respective ends 350a, 351a take the form of an arrow head on the end of a main rod like body 350b, 351b. The breaking elements 350, 351 therefore each comprise a respective step 350c, 351c in width between the respective ends 350a, 351a and respective bodies 350b, 351b. The respective bodies 350b, 351b are received through the respective openings 331, 333. The width of the respective ends 350a, 351a at the respective steps 350c, 351c, being larger than that of the respective openings 331, 333, prevents the respective breaking elements 350, 351 from being removed entirely radially outwardly through the respective openings 331, 333. The second opening 333 and the second breaking element 351 are located on an opposite side of the channel 332 to the first opening 331 and the first breaking element 350. The second opening 333 and the second breaking element 351 are located at the same position along the longitudinal axis P-P of the mouth-end section 302 to the first opening 331 and the first breaking element 350. The first breaking element 350 and the second breaking element 351 are thereby operable by a user to slide towards each other along an axis substantially perpendicular to a longitudinal axis P-P of the mouth-end section 302. A breakable flavour element 324 received in the channel 332 of the mouth- end section 302 may therefore be broken between the narrow ends 350a, 351a of the first breaking element 350 and the second breaking element 351 respectively. There being two operable breaking elements 350, 351 reduces the force required per breaking element 350, 351 to break the breakable flavour element 224 in the channel 332 there between. The two breaking elements 350, 351 being opposing allows for convenient manual operation of the breaking elements 350, 351, for example using a thumb and an index finger of a user's hand, respectively.

The mouth-end section 302 illustrated in Figures 3a and 3b comprises a first reshaping element 370 and a second reshaping element 371 each extending along a portion of the channel 332 on opposite sides of the channel 332. The reshaping elements 370, 371 are internal of the side wall 330 of the mouth-end section 302. The reshaping elements 370, 371 are moveable in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 302. Specifically, the first reshaping element 370 comprises at least one elongate slot 397 for receiving a pin 396 of the mouth-end section 302. Similarly, the second reshaping element 371 comprises at least one elongate slot 397a for receiving a pin 396a of the mouth-end section 302. The elongate slots 397, 397a extend radially of the longitudinal axis P-P of the mouth-end section 302, hence allowing sliding movement of the respective reshaping elements 370, 371 relative to the mouth-end section 302 in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 302. The reshaping elements 370, 371 are oriented substantially at right angles about the longitudinal axis P-P relative to the breaking elements 350, 351. Movement of the reshaping elements is therefore along an axis substantially at right angles to the axis along which the breaking elements 359, 351 are moveable.

The reshaping elements 370, 371 each contact the breaking elements 350, 351 at their respective narrowing ends 350a, 351a. The reshaping elements 370, 371 are shaped so that a surface of the reshaping element 370, 371 for contacting the breaking element 350, 351 lies in a plane substantially parallel to a plane defined by the narrowing end 350a, 351a of the breaking element 350, 351. When the breaking elements 350, 351 are pushed radially inwardly towards the channel 332, for example so as to break a breakable flavour element 324 received therein, the respective narrowing ends 350a, 351a therefore exert a force on the reshaping elements 370, 371 that causes the reshaping elements 370, 371 to slide radially outwardly away from the channel 332.

The mouth end section 302 comprises a first biasing means 399, for example a spring 399, which biases the first reshaping element 370 away from an inner surface of the side wall 330 and towards the channel 332. Similarly, the mouth end section 302 comprises a second biasing means 398, for example a spring 398, which biases the second reshaping element 371 away from an inner surface of the side wall 330 and towards the channel 332. The reshaping elements 370, 371 may therefore be slid back radially inwardly towards the channel 332, under the force of the respective biasing means 398, 399.

The reshaping elements 370, 371 are oriented at or near a right angles about the longitudinal axis P-P of the mouth-end section 302 with respect to the breaking elements 350, 351. When the breaking element 350 breaks (e.g. crushes) the breakable flavour element 324 laterally, the breakable flavour element 324 may deform so at to reduce in width along the breaking axis (i.e. the axis along which the breaking elements 350, 351 slide), and to increase in width along an axis perpendicular to the breaking axis. The reshaping elements 370, 371 being oriented at right angles to the breaking elements 350, 351 allows the reshaping elements 370, 371 to apply, via the biasing means 399, 398, a returning (squeezing) force along an axis substantially perpendicular to the breaking axis. This reduces the width of the breakable flavour element 324 along the axis perpendicular to the breaking axis, and increases the width of the breakable flavour element 324 along the breaking axis, thereby returning the breakable flavour element towards its original shape prior to breaking.

The reshaping elements 370, 371 thereby allow reshaping of the breakable flavour element 324 received in the channel 332 after a deformation of the breakable flavour element 324 due to breaking of the breakable flavour element 324 in use. This reshaping reduces the increase in pressure drop in the breakable flavour element 324 that may result from breaking of the breakable flavour element 324. The reshaping therefore allows for a consistent delivery of aerosol from the overall device 300 whether or not the breakable flavour element 324 has been broken.

Referring now to the sequence shown in Figures 3a and 3b, in Figure 3a, a breakable flavour element is received in the channel 332, and the first breaking element 350 and the second breaking element 351 are each in the first position, i.e. away from the breakable flavour element 324. A user may wish to break the breakable flavour element 324, for example, so as to change a flavour of the aerosol produced by the device 300. A user may therefore push the first breaking element 350 and the second breaking element 351 radially inwards towards each other, i.e. slide the first breaking element 350 and the second breaking element 351 to the second position (Figure 3b). The breakable flavour element 324 is thereby broken (e.g. crushed) between the first breaking element 350 and the second breaking element 351, and being broken (e.g. crushed), releases a flavour to flavour the aerosol passing there through. In being broken (e.g. crushed), the breakable flavour element 324 is deformed such that its width along an axis perpendicular to the breaking axis increases. The movement of the first breaking element 350 and the second breaking element 351 radially inwards causes the reshaping elements 370, 371 to move radially outwards away from the channel along the axis perpendicular to the breaking axis, hence energising the biasing means 398, 399. (Figure 3b). A user may then cease pushing on the breaking elements 350, 351. The biasing means 398, 399 cause the reshaping elements 370, 371 to return radially inwardly to their original positions, and in so doing reshapes the breakable flavour element 324 towards its original form. The movement of the reshaping elements 370, 371 radially inwardly causes the breaking elements to slide radially outwardly to the first position (Figure 3a).

Although the description of the other example receptacle sections herein does not refer explicitly to a 'reshaping elements' or 'reshaping' of a breakable flavour element, it will be readily appreciated that this feature can be applied equally to the other examples.

Referring now to Figures 4a to 4c, there is illustrated schematically cross section of part of an aerosol provision article 400 with another example receptacle section 402 in different configurations. In this example, the receptacle section 402 is again a mouth- end section 402. For brevity, features in Figure 4 and the functioning thereof that are the same or similar to those features already described with reference to Figure 3a to 3c are given similar reference numerals to as in Figure 3 but increased by 100, and will not be described in detail again.

As in the mouth-end section 202 illustrated in Figures 2, the mouth-end section 402 illustrated in Figures 4a to 4d defines a channel 432 for having a breakable flavour element 424 comprising a breakable flavour capsule 426 installed therein. The mouth- end section 402 comprises a removable mouth portion 202a defining an outlet 434 for inhalation of aerosol produced by the overall device 400. When the mouth portion 402a is removed, an opening 444 of the channel is exposed, allowing installation of a breakable flavour element 424 therein. The mouth-end section 402 comprises a connecting means 428 for releasably connecting the mouth-end section 402 to a body 406 of the overall device 400. The mouth-end section 402 comprises a breaking element 450 moveable along an axis substantially perpendicular to the longitudinal axis P-P of the mouth-end section 402 between a first position (see Figure 4a) for allowing installation of the breakable flavour 424 element in the channel 432, and a second position (see Figure 4b) for breaking said breakable flavour element 424 installed in the channel 432.

However, in this example, the breaking element 450 comprises a resilient member 450 extending along a portion of the channel 432 of the mouth-end section 402, i.e. extending along the channel 432 in a direction substantially parallel to the longitudinal axis P-P of the mouth-end section 402. The resilient member 450 is operable by a user to bend or flex between the first position (see Figure 4a) and the second position (see Figure 4b). In the first position (Figure 4a) the resilient member 450 lies substantially parallel with the channel thereby allowing insertion of a breakable flavour element 424 therein. In the second position (see Figure 4b) a portion 450a of the resilient member 450 protrudes into the channel 432, thereby to break (e.g. crush) the breakable flavour element 424 received in the channel 432. In this example, the resilient member 450 forms part of the side wall 430 of the mouth-end section 402 defining the channel 432. One end 453 of the resilient member 450 is free to move relative to the side wall 430. The end 453 of the resilient member 450 is therefore bendable relative to the remainder of the side wall 430 into the channel 432, thereby to break the breakable flavour element 424 received in the channel 432. The breakable flavour element 424 is supported in the channel 432 by a support member 456.

The resilient member 450 comprises, at the end 453 of the resilient member 450 that is free to move, an inward protruding portion 450a protruding from the resilient member 450 towards the channel 432. The inward protruding portion 450a is for contacting the breakable flavour element 424 received in the channel 432, thereby to break said breakable flavour element 424 received in the channel 432 when the resilient member 450 is bent to the second position. The inward protruding portion 450a increases the pressure exerted on the breakable flavour element 424 when the resilient member 450 is bent to the second position for a given lateral force exerted on the resilient member 450 by a user. The inward protruding portion 450a therefore increases the ease with which a user may break the breakable flavour element 424 received in the channel 432. Although this 'inward protruding portion' feature is not explicitly mentioned in every example described herein, it will be appreciated that this feature may be applied equally to those other examples. The mouth-end section 402 comprises a reacting element 458 extending along a portion of the channel 432 of the mouth-end section 402, i.e. extending along the channel 432 in a direction substantially parallel to the longitudinal axis P-P of the mouth-end section 402. The reacting element 458 is positioned on an opposite side of the channel 432 to the resilient member 450, and hence reacts the force exerted on the breakable flavour element 426 by the resilient member 450 when operated by the user. The breakable flavour element 426 is therefore broken (e.g. crushed) between the resilient member 450 operable by the user and the reacting element 458. Similarly to the resilient member 450, the reacting element 458 comprises an inward protruding portion 458a that protrudes into the channel 432, and which is opposed to the inward protruding portion 450a of the resilient member 450. This (further) increases the pressure exerted on the breakable flavour element 424 when the resilient member 450 is operated by a user, hence (further) increasing the ease with which a user may break a breakable flavour element 424 received in the channel 432. Referring to the sequence illustrated in Figures 4a to 4c, in Figure 4a, the mouth portion 402a is removed from the mouth-end section 402, thereby to allow an insertion, removal or replacement of the breakable flavour element 424 into the channel 432. A user may replace the mouth portion 402a into the mouth-end section 402. In Figure 4a, a breakable flavour element 424 is received in the channel 432, and the resilient member 450 is in the first portion, i.e. substantially parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 402. At some later stage, a user may wish to break (activate) the breakable flavour element so that aerosol inhaled from the device 400 is flavoured there by. A user may therefore push (arrow I) laterally (i.e. in a direction perpendicular to the longitudinal axis P-P of the mouth-end section 402) against the resilient member 450. This causes the resilient member 450 to bend so that the inward protruding portion 450a protrudes into the channel 432 and breaks (activates) the breakable flavour element 424 between the inward protruding portion 450a of the resilient member and the inward protruding portion 458a of the resisting element 458, thereby releasing flavour from the breakable flavour capsule 426. The resilient member 450 is now in the second position (see Figure 4b). When a user ceases to push on the resilient member 450, due to its resilience (natural springiness), the resilient member 450 returns to the first portion, i.e. returns so as to be substantially parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 402.

Referring now to Figures 5a to 5d, there is illustrated schematically cross sections of a part of an aerosol provision article 500 with another example receptacle section 502 in different configurations. In this example, the receptacle section is again a mouth-end section 502. For brevity, features in Figures 5a to 5d and the functioning thereof that are the same or similar to those features already described with reference to Figure 4a to 4c are given similar reference numerals to as in Figures 4a to 4d but increased by 100, and will not be described in detail again.

The mouth-end section 502 illustrated in Figures 5a to 5d is similar to the mouth-end section 402 illustrated in Figures 4a to 4c. A breakable flavour element 524 comprising a breakable flavour capsule 526 is received in a channel 532 of the mouth- end section 502. A first resilient member 550 is bendable along an axis parallel to the longitudinal axis of the mouth-end section 502, and is thereby operable between first and second positions as described above with respect to the resilient member 450 described above with reference to Figure 4.

However, the mouth-end section 502 illustrated in Figures 5a to 5d comprises a second resilient member 551. The second resilient member 551 is essentially the same as the first resilient member 550 described above, and so will not be described in detail. Similarly to the first resilient member 550, the second resilient member 551 is operable by a user to bend between a first position (as in Figure 5b) in which the resilient member 551 does not extend into the channel 532, and a second position (as in Figure 5c) in which it does. The second resilient member 551 is located on an opposite side of the channel 532 to the first resilient member 550. The second resilient member 551 is located at the same position along the longitudinal axis P-P of the mouth-end section 502 to the first resilient member 550. The first resilient member 550 and the second resilient member 551 are thereby operable by a user to bend towards each other. A breakable flavour element 524 received in the channel 532 of the mouth-end section 502 may therefore be broken (e.g. crushed) between the first resilient member 550 and the second resilient member 551. There being two operable resilient members 550, 551 reduces the force required per resilient member 550, 551 to break (e.g. crush) the breakable flavour element 524 in the channel 532 there between. The two breaking elements 550, 551 being opposing allows for convenient manual operation of the resilient member 550, 551, for example using a thumb and an index finger of a user's hand, respectively.

The mouth-end section 502 comprises a resilient outer portion 553. The resilient outer portion 553 is generally annular in shape and surrounds the side wall 530, and the resilient members 550, 551 of the mouth-end section 502. The resilient outer portion 553, similarly to the resilient members 550, 551 is resilient in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 502. The resilient outer portion 553 comprises ribbing on its outer surface to facilitate a user's grip when squeezing laterally on the mouth-end section 502 to bend the resilient members 550, 551 when breaking (activating) the breakable flavour element 524 received in the channel 532. The resilient outer portion 553 is connected (e.g. fixedly connected) to the resilient members 550, 551 to bias the resilient members 550, 551 to the first position. It will be appreciated that the resilient outer portion 553 may have similar functionality as the reshaping elements 370, 371 described above with respect to Figure 3, and this functionality will not be described again in detail. Suffice to say that the resilient outer portion 553 may help reshape the breakable flavour element after breaking by exerting a reshaping force along an axis perpendicular to the breaking axis. Referring to the sequence illustrated in Figures 5a to 5d, in Figure 5a, the mouth portion 502a is removed from the mouth-end section 502, thereby to allow an insertion (arrow J) of the breakable flavour element 524 into a receiving portion 580 of the mouth portion 502a. A user may push (arrow K) the mouth portion 502a into the channel 532 of the mouth-end section 502, thereby installing the breakable flavour element 524 into the channel 532. In Figure 5b, the breakable flavour element 524 is received in the channel 532, and the resilient members 551, 553 are in the first portion, i.e. parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 502. At some later stage, a user may wish to break (activate) the breakable flavour element 524 so that aerosol inhaled from the device 500 is flavoured there by. A user may therefore push (arrows L) laterally (i.e. in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 502) against the resilient members 550, 551, via the resilient outer portion 553. This causes the resilient members 550, 551 to bend inwards towards each other so as to protrude into the channel 532 and break the breakable flavour element 524, thereby releasing flavour from the breakable flavour capsule 526. The resilient member 550 is now in the second position (see Figure 5c). When a user ceases to push on the resilient members 550, 551, due to the resilience (natural springiness) of the resilient members 550, 551, (or alternatively or additionally due to the resilience of the resilient outer portion 553 to which the resilient members 550, 551 are connected), the resilient members 550, 551 return to their respective first positions, i.e. return so as to be parallel (unbent) with respect to the longitudinal axis P- P of the mouth-end section 502 (Figure 5d).

Referring now to Figures 6a to 6c, there is illustrated schematically cross sections of a part of an aerosol provision article 600 with another example receptacle section 602 in different configurations. In this example, the receptacle section is again a mouth-end section 602. For brevity, features in Figure 6 and the functioning thereof that are the same or similar to those features already described with reference to Figure 5a to 5d are given similar reference numerals to as in Figure 5 but increased by 100, and will not be described in detail again.

The mouth-end section 602 of Figures 6a to 6d is similar to the mouth-end section 502 illustrated in Figures 5a to 5d. The mouth-end section 602 comprises resilient members 650, 651 on opposite sides of a channel 632 that has a breakable flavour element 624 comprising a breakable flavour capsule 626, received therein. The resilient members 650, 651 are operably bendable into the channel 632, from the first position to the second position as described above with respect to Figures 5a to 5d, thereby to break the breakable flavour element 624. However, in this example, the resilient members 650, 651 each comprise a respective inwardly protruding portion 650a, 651a that protrudes radially inwardly toward the channel 632, for breaking a breakable flavour element 624 received therein.

In this example, the resilient members 650, 651 are received in a mouth portion 602a for receipt into a user's mouth. The mouth portion 602a defines an opening 634 to allow a user to inhale aerosol from the device 600, via the channel 632. The mouth portion 602a is removable from the mouth-end section 602, thereby to expose the resilient members 650, 651, to allow a breakable flavour element 624 to be received there between. The mouth portion 602a is connected (tethered, leashed) to the mouth- end section 602 by a flexible leash 657. This leash 657 helps prevent the mouth portion 602a from being misplaced when removed from the mouth-end section 602.

A side wall 642 of the mouth portion 602a comprises a resilient portion 642a. The resilient portion 642a is generally annular in shape, and when the mouth portion 602a is connected to the mouth-end section 602 such that the resilient members 650, 651 are received in the mouth portion 602a, the resilient portion surrounds the resilient members 650, 651. Similarly to the resilient members 650, 651, the resilient portion 642a is resilient in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 602.

Referring to the sequence illustrated in Figures 5a to 5c, in Figure 6a, the mouth portion 602a is removed from the mouth-end section 602, thereby to allow an insertion (arrow Q) of the breakable flavour element 624 into the channel 632, between the resilient members 650, 651. A user may manipulate (arrow R) the mouth portion 602a over the resilient members 650, 651 so as to connect the mouth portion 602a to the mouth-end section 602, thereby installing the breakable flavour element 624 into the mouth end section 602 (see Figure 6a). At some later stage, a user may wish to break (activate) the breakable flavour element 624 so that aerosol inhaled from the device 600 is flavoured there by. A user may therefore push (squeeze) (arrows S) laterally (i.e. in a direction substantially perpendicular to the longitudinal axis P-P of the mouth-end section 602) against the resilient members 650, 651, via the resilient portion 642a of the mouth portion 602a. This causes the resilient members 650, 651 to bend inwards towards each other so as to protrude into the channel 632 and break, via the respective inward protruding portions 650a, 651a, the breakable flavour element 624, thereby releasing flavour from the breakable flavour capsule 626. The resilient members 650, 651 are now in the second position (see Figure 6b). When a user ceases to push on the resilient members 650, 651, due to the resilience (natural springiness) of the resilient members 650, 651, the resilient members 650, 651 return to their respective first positions, i.e. return so as to be parallel (unbent) with respect to the longitudinal axis P- P of the mouth-end section 502 (Figure 6c). Referring now to Figures 7a to 7d, there is illustrated schematically cross sections of a part of an aerosol provision article 700 with another example receptacle section 702 in different configurations. In this example, the receptacle section is again a mouth-end section 702. For brevity, features in Figure 7 and the functioning thereof that are the same or similar to those features already described with reference to Figure 6a to 6c are given similar reference numerals to as in Figure 6 but increased by 100, and will not be described in detail again.

The mouth-end section 702 of Figures 7a to 7d is similar to the mouth-end section 502 illustrated in Figures 6a to 6c. The mouth-end section 702 comprises resilient members 750, 751 on opposite sides of a channel 732 that has a breakable flavour element 724 comprising a breakable flavour capsule 726, received therein. The resilient members 750, 751 are operably bendable into the channel 732, from the first position to the second position as described above with respect to Figures 6a to 6c, thereby to break the breakable flavour element 724.

However, unlike the resilient members 650, 651 described with reference to Figures 6a to 6c, the resilient members 750, 751 are not bent together laterally by a user applying a lateral squeezing force to the resilient members 750, 751, but are bent together by the sliding of an operation element 759 substantially parallel to the longitudinal axis P-P of the mouth-end section 702. Specifically, the mouth portion 702a of the mouth-end section 702, when installed in the mouth-end section 702, is a housing 702a in which the resilient members 750, 751 and the breakable flavour element 724 is housed. The operation element 759 is slidably mounted to the mouth portion 702a thereby allowing sliding movement of the operation element 759 relative to the mouth portion 702a substantially parallel to the longitudinal axis P-P of the mouth-end section 702. In this example, the operation element 759 is generally annular in shape and is arranged around a circumference of the mouth portion as a collar 759.

The resilient members 750, 751 each comprise an outward protruding portion 750b, 751b. The outward protruding portion 750b, 751b protrude out from the respective resilient member 750, 751 away from the channel 732, and are for contacting the operation element 759 of the mouth-end section 702.

The operation element 759 is operable by a user to slide between a first operation element position (see Figure 7b) and a second operation element position (see Figure 7c). In the first operation element position (Figure 7b) the operation element 759 is positioned relatively away from (i.e. axially distant from) the outward protruding portion 750b, 751b of the resilient member 750, 751. In this position, the operation element 759 does not exert any radially inward force on the resilient member 750, 751, and the resilient member 750, 751 remains in the first position. In the second operation element position (Figure 7c) the operation element 759 is positioned relatively towards (i.e. axially proximal to) the outward protruding portion 750b, 751b of the resilient member 750, 751. In this position, the operation element 759 displaces the outward protruding portion 750b, 751b and hence the resilient member 750, 751 radially inwardly towards the channel 732, i.e. to the second position. Sliding of the operation element 759 relative to the mouth portion 702a substantially parallel to the longitudinal axis P-P of the mouth-end section 702, from the first operation element position (Figure 7b) to the second operation element position (Figure 7c), thereby causes bending of the resilient member 750 from the first position to the second position, thereby breaking said breakable flavour element 724 received in the channel 732. The operation element 759 comprises an inward protruding portion 759a protruding out of the operation element 759 towards the resilient member 750, 751. When the operation element 759 is in the second operation element position (Figure 7b), the inward protruding portion 759a of the operation element 759 is longitudinally (axially) aligned with the outward protruding portion 750b, 751b of the resilient member 750, 751. The inward protruding portion 759a of the operation element 759 thereby increases the displacement (bending) of the resilient members 750, 751 into the channel 732, and thereby provides efficient breaking of the breakable flavour element 724 received in the channel 732. The operation element 759 is slidable beyond the second operation element position to a third operation element position (see Figure 7d). In the third operation element position, the inward protruding portion 759a of the operation element 759 is slid beyond, and hence longitudinally (axially) misaligned with the outward protruding portion 750b, 751b of the resilient member 750, 751. In this position, as with the first operation element position, the operation element 759 does not exert any radially inward force on the resilient member 750, 751, and the resilient member 750, 751 returns again by virtue of its resilience (natural springiness) to the first position. In this example, the operation element 759 in the third operation element position closes off a gap 754 in the mouth portion 702a, thereby to seal the flow path through the mouth-end section 702 from the body 706 of the overall device 700 to the outlet 734 of the mouth portion 734.

Referring to the sequence illustrated in Figures 7a to 7d, in Figure 7a, the mouth portion 702a is removed from the mouth-end section 702, thereby to allow an insertion of the breakable flavour element 724 between the resilient members 750, 751. A user may attach the mouth portion 702a to the mouth-end section 702, thereby housing the resilient members 750, 751 and the breakable flavour element 724 in the mouth portion 702a (see Figure 7b). In Figure 7b, the operation element 759 is in the first operation element position, and hence the resilient members 751, 750 are in the first position, i.e. parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 702. At some later stage, a user may wish to break (activate) the breakable flavour element 724 so that aerosol inhaled from the device 700 is flavoured there by. A user may therefore push, pull, or otherwise manipulate the operation element 759 relative to the mouth-end section 702 towards the body 706 of the device 700 in a direction substantially parallel to the longitudinal axis P-P of the mouth-end section 702. This causes the inward protruding portions 759a of the operation element 759 to push against the outward protruding portion 750b, 751b of the resilient members. This pushing results in a radially inward force that causes the resilient members 750, 751 to bend inwards towards each other so as to protrude into the channel 732 and break the breakable flavour element 724, thereby releasing flavour from the breakable flavour capsule 726 (see Figure 7c). The operation element 759 is now in the second operation element position, and the resilient members 750, 751 are now in the second position (see Figure 7c). A user may continue to push, pull, or otherwise manipulate the operation element 759 relative to the mouth-end section 702 further towards the body 706 of the device 700 in a direction substantially parallel to the longitudinal axis P-P of the mouth-end section 702, until the operation element 759 is in the third operation element position (Figure 7d). The resilient members 750, 751 are therefore no longer displaced by the operation element 759. Due to the resilience (natural springiness) of the resilient members 750, 751, the resilient members 750, 751 return to their respective first positions, i.e. return so as to be substantially parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 702 (Figure 7d).

Referring now to Figures 8a to 8e, there is illustrated schematically cross sections of a part of an aerosol provision article 800 with another example receptacle section 802 in different configurations. The cross sections of Figures 8c and 8e correspond to the cross sections of Figures 8b and 8c respectively, but the cross sections 8c and 8e are taken in a plane perpendicular to the plane in which Figures 8b and 8c are presented, respectively. In this example, the receptacle section 802 is again a mouth- end section 802. For brevity, features in Figure 8 and the functioning thereof that are the same or similar to those features already described with reference to Figure 7a to 7d are given similar reference numerals to as in Figures 7a to 7d but increased by 100, and will not be described in detail again. The mouth-end section 802 of Figures 8a to 8e is similar to the mouth-end section 702 illustrated in Figures 7a to 7d. The mouth-end section 702 comprises resilient members 850, 851 on opposite sides of a channel 832 that has a breakable flavour element 824 comprising a breakable flavour capsule 826, received therein. The resilient members 850, 851 are operably bendable by an operation element 890 into the channel 832, from the first position to the second position as described above with respect to Figures 8a to 8d, thereby to break the breakable flavour element 824. The resilient members 850, 851 each comprise an outward protruding portion 850b, 851b protruding out from the respective resilient member 850, 851 away from the channel 832 for contacting the operation element 890.

However, unlike the resilient members 750, 751 described with reference to Figures 7a to 7d, the resilient members 850, 851 are not bent together laterally by the sliding of an operation element 759 substantially parallel to the longitudinal axis P-P of the mouth-end section 702, but are bent together laterally by the rotation of an operation element 890 about the longitudinal axis P-P of the mouth-end section 802.

Specifically, the mouth portion 802a of the mouth-end section 802, when installed in the mouth-end section 802, is a housing 802a in which the resilient members 850, 851 and the breakable flavour element 824 is housed. The operation element 890 is rotatably mounted to the mouth portion 802a thereby allowing rotation of the operation element 890 relative to the mouth portion 802a about the longitudinal axis P- P of the mouth-end section. In this example, the operation element 890 is generally annular in shape and is arranged around a circumference of the mouth portion as a collar 890.

The operation element 890 defines a first inner radial dimension Dl and a second, smaller inner radial dimension D2 (best seen in Figures 8c and 8e). The operation element 890 is operable by a user to rotate relative to the moth portion 802a about the longitudinal axis P-P of the mouth-end section 802 between a first operation element orientation (see Figures 8b and 8c)) and a second operation element orientation (see Figures 8d and 8e). In the first operation element orientation (Figure 8b and 8c) the first inner radial dimension D 1 is rotationally aligned with the resilient member 850, 851. In this orientation, the resilient members 850, 851 experience the larger inner radial dimension Dl of the operation element. The inner radial dimension is larger than the distance between the outward protruding portions 850b, 851b of the respective resilient members 850, 851 when substantially parallel to the longitudinal axis P-P of the mouth-end section 802, and so the operation element 890 does not displace the resilient members 850, 851. The resilient members 850, 851 therefore remain in the first position. In the second operation element orientation (Figure 8d and 8e) the second inner radial dimension D2 is rotationally aligned with the resilient member 850, 851. In this orientation, the resilient members 850, 851 experience the smaller inner radial dimension D2 of the operation element 890. The second inner radial dimension D2 is smaller than the distance between the outward protruding portions 850b, 851b of the resilient members 850, 851 when substantially parallel to the longitudinal axis P-P of the mouth-end section 802, and so the operation element 890 displaces the resilient members 850, 851 inwardly towards the breakable flavour element 824. The resilient members 850, 851 are therefore forced to the second position, and inwardly protruding portions 850a, 851a of resilient members 850, 851 contact and break the breakable flavour element 824 received there between. Rotation of the operation element 890 relative to the mouth portion 802a about the longitudinal axis P-P of the mouth-end section 802, from the first operation element orientation (Figure 8b and 8c) to the second operation element orientation (Figure 8d and 8e), thereby causes bending of the resilient members 850, 851 from the first position to the second position, thereby breaking said breakable flavour element 824 received in the channel 832.

The first radial dimension Dl is oriented at right angles about the longitudinal axis P-P of the mouth-end section 802 with respect to the second radial dimension D2. In this case, in order to change from the first operation element orientation to the second operation element orientation, a user rotates the operation element 890 a quarter turn (i.e. by 90°) about the longitudinal axis P-P of the mouth-end section 802.

As best seen in Figures 8c and 8e, the inner radial dimension of the operation element 890 varies gradually from the first inner radial dimension Dl to the second inner radial dimension D2. That is, there is not a step change in the inner radial dimension of the operation element 890, but rather a gradual increase from small to large at successive points around the circumference of the operation element 890. This gradual increase (or 'gearing') provides a reduction in the degree to which the resilient members 850, 851 are bent for a given degree of rotation of the operation element 890 about the longitudinal axis. This 'gearing' can reduce the torque required to be exerted on the operation element 890 to break the breakable flavour element 824, and hence provides for easy and convenient breaking of a breakable flavour element 824 installed into an overall device 800.

Referring to the sequence illustrated in Figures 8a to 8e, in Figure 8a, the mouth portion 802a is removed from the mouth-end section 802, thereby to allow an insertion of the breakable flavour element 824 between the resilient members 850, 851. A user may attach the mouth portion 802a to the mouth-end section 802, thereby housing the resilient members 850, 851 and the breakable flavour element 824 in the mouth portion 802a (see Figure 8b). In Figures 8b and 8c, the operation element 890 is in the first operation element orientation, and hence the resilient members 851, 850 are in the first position, i.e. parallel (unbent) with respect to the longitudinal axis P-P of the mouth- end section 802. At some later stage, a user may wish to break (activate) the breakable flavour element 824 so that aerosol inhaled from the device 800 is flavoured there by. A user may therefore rotate (arrow M) the operation element 890 relative to the mouth- end section 802 about the longitudinal axis P-P of the mouth-end section 802 by 90°. This causes the inner surface of the operation element 890 at the second radial dimension D2 to push against the outward protruding portion 850b, 85 lb of the resilient members. This pushing results in a radially inward force that causes the resilient members 850, 851 to bend inwards towards each other so as to protrude into the channel 832 and break the breakable flavour element 824, thereby releasing flavour from the breakable flavour capsule 826 (see Figures 8d and 8e). The operation element 890 is now in the second operation element orientation, and the resilient members 850, 851 are now in the second position (see Figure 8d and 8e). A user may continue to rotate the operation element 890 (or alternatively rotate the operation element back) until the operation element 890 is back in the first operation element orientation (as in Figures 8b and 8c). The resilient members 850, 851 are therefore no longer displaced by the second inner radial dimension D2 of the operation element 890. Due to the resilience (natural springiness) of the resilient members 850, 851, the resilient members 850, 851 return to their respective first positions, i.e. return so as to be parallel (unbent) with respect to the longitudinal axis P-P of the mouth-end section 802 (as in Figures 8b and 8c).

Although in the examples described above the various receptacle sections 102, 202, 302, are generally described as being arranged to break a breakable flavour element 124, 224, 324 etc. by crushing a flavour capsule 126, 226, 326 etc., it will be appreciated that there are other ways in which a flavour element 124, 224, 324 etc. may be broken. For example, alternatively or in addition, the receptacle sections 102, 202, 302 may break a flavour element 124, 224, 324 etc. by piercing, puncturing, cutting, or slicing a flavour capsule 126, 226, 326 etc. of a flavour element 124, 224, 324 etc. For example, breaking elements (such as for example resilient members 250, 251, 350, 351, etc. or inwardly protruding portions 560, 660 etc.) may comprise a spike or other sharp protrusion for piercing or puncturing a flavour capsule 126, 226, 326, or an edge for cutting or slicing a flavour capsule 126, 226, 326 etc. of a flavour element 124, 224, 324 etc. for example.

Although in the examples described above the various receptacle sections 102, 202, 302, were described as being arranged to break a breakable flavour element 124, 224, 324 etc. after an installation of the breakable flavour element 124, 224, 324 etc. into the receptacle section, this is not essential, and the various receptacle sections 102, 202, 302 may be arranged to activate any suitable activatable element 124, 224, 324 etc. by applying a force to activate the activatable element 124, 224, 324 etc. after an installation of the activatable element 124, 224, 324 etc. into the receptacle section 102, 202, 302 etc. In other words, rather than at least one breaking element operable to break a breakable flavour element, the receptacle section may comprise at least one activating element operable to apply, after an installation of said activatable element in the receptacle section by a user, a force to the activatable element to activate the activatable element.

In some examples, the activatable element may comprise a reservoir of flavourant (for example in the form of a liquid and/or gel). The reservoir may be wrapped or embedded in a suitable carrier material, such as cellulose acetate. The reservoir may have resilient or deformable walls. The reservoir may have an aperture allowing flavourant to be released from the reservoir to the carrier material. When a force is applied to the activatable element by an activating element of a receptacle section as described in detail in any one of the various above examples (for example via breaking elements such as resilient members 250, 350, 351, 450 etc.), the reservoir is squeezed (deformed) and the flavourant is thereby forced from the reservoir through the aperture into the carrier material. The receptacle section thereby activates an activatable flavour element by applying a force, after an installation of the activatable flavour element into the receptacle section, to the activatable element. In some examples, the activatable element may comprise flavour material, for example solid material, which when ground, exposed, or otherwise suitably physically activated, releases a flavourant. The flavour material may be, for example, ground tobacco. The flavour material may be for example wrapped partially or wholly in a wrapper, and/or the flavour material may be supported in a resilient housing, for example a plastic housing, or may be held or embedded in a suitable carrier material such as cellulose acetate. When a force is applied to the activatable element by a receptacle section as described in detail in any one of the various above examples above (for example via resilient members 250, 350, 351, 450 etc.), the solid material is exposed or otherwise suitably physically activated, and a flavourant (or an increase and/or change in flavourant) is released thereby to impart a flavour (or increased and/or different flavour) to the aerosol flow. The receptacle section thereby activates an activatable flavour element by applying, after an installation of the activatable flavour element into the receptacle section, a force to activate the activatable element.

Although in the examples described above, the activatable element 124, 224, 324 etc. received in the various receptacle sections 202, 302, 402 etc. is a flavour element 124, 224, 324 etc. and is for releasing a flavourant to impart a flavour to the aerosol when the aerosol flows through the flavour element 124, 224, 324 etc., this is not essential and instead (or in addition) the activatable element 124, 224, 324 etc. may be for modifying a property of the aerosol other than (or in addition) to flavour, for example comprise a substance for modifying a property of the aerosol other than (or in addition) to flavour.

In some examples, the element 124, 224, 324 etc. may comprise a substance that modifies one or more other organoleptic properties of the aerosol (e.g. modifying the feel or smell or look of the aerosol to the user).

In some examples, the element 124, 224, 324 etc. may comprise a substance that modifies the PH of the aerosol by either lowering or raising the PH (e.g. modifying the acidity or the basicity of the aerosol).

In some examples, the element 124, 224, 324 etc. may comprise a substance that modifies (e.g. reduce) the amount of aldehydes in the aerosol.

In some examples, the element 124, 324, 324 etc. may comprise a substance that modifies different combinations of two or more of these or indeed other properties of the aerosol.

Although in the above described examples, the device 100, 200, 300 etc. generates the aerosol by heating a liquid (the device is of type commonly referred to as an e-cig), this is not essential and in other examples, the device may generate the aerosol by heating, but not burning (combusting), a material, for example comprising a solid material, that may contain for example tobacco (e.g. a device sometimes referred to as a Tobacco Heating Product (THP) device).

In the above examples, the liquid container 122 was cylindrical in shape and defined a cylindrical channel 104 running through the length of the liquid container 122. However, in other examples, the liquid container may not be annular in shape, and/or the liquid container may comprise an outer shell that defines an annular channel between the liquid container and the outer shell through which vapour or aerosol may also, or instead, pass.

Indeed, it will be readily appreciated that there are many configurations of aerosol provision articles such as so called e-cigarette devices (some of which not having refillable liquid containers integral to the device as such, but rather, for example, replaceable cartridges, for example comprising integral atomisers, i.e. so called "cartomizers") and that the above examples may also be applied to these or other configurations or to other aerosol provision articles.

In use, the material of the flavour element may be heated by vapour or aerosol with a temperature higher than the temperature of the material. It will be appreciated that any temperature above ambient temperature of the material and/or above the ambient temperature of the device as a whole will improve release of constituents from the solid material.

As used herein, the terms "flavour" and "flavourant" may refer to materials which, where local regulations permit, may be used to create a desired taste or aroma in a product for adult consumers. They may include extracts (e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha), flavour enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example, oil, liquid, solid, or powder. For example, a liquid, oil, or other such fluid flavourant may be impregnated in a porous solid material so as to impart flavour and/or other properties to that porous solid material.
