AEROSOL-GENERATING DEVICE WITH CARTRIDGE RELEASE SYSTEM

Description

[0001] This disclosure relates to aerosol-generating devices and to systems for gripping and releasing cartridges containing an aerosol-forming substrate for use in aerosol-generating devices. This disclosure also relates to systems for removing and discarding cartridges used in aerosol-generating devices. More particularly, this disclosure relates to gripping and releasing systems that can be used to remove and discard cartridges used in shisha devices.

[0002] Traditional shisha devices are used to smoke tobacco and are configured such that vapor and smoke pass through a water basin before inhalation by a consumer. Shisha devices may include one outlet, or more than one outlet so that the device may be used by more than one consumer at a time. Use of shisha devices is considered by some to be a leisure activity and a social experience. An example of prior art is given by the patent documentation WO 2017/178931 A1, which discloses an aerosol-generating element comprising a body and a receptacle for receiving a cartridge comprising an aerosol-forming substrate;a vessel having a liquid fill level and defining a head space outlet above the liquid fill level;a conduit for conveying airflow from the receptacle to the vessel; and a cap engageable with the body.

[0003] Typically, traditional shishas are used in combination with a substrate, sometimes referred to in the art as hookah tobacco, tobacco molasses, or simply as molasses. Traditional shisha substrates are relatively high in sugar (in some cases, up to ~50 % vs. the ~20 % typically found in conventional tobacco substrates, such as in combustible cigarettes). The tobacco used in shisha devices may be mixed with other ingredients to, for example, increase the volume of the vapor and smoke produced, to alter flavor, or both.

[0004] Traditional shisha devices employ charcoal, such as charcoal pellets to heat and sometimes combust the tobacco substrate to generate an aerosol for inhalation by a user. Using charcoal to heat the tobacco may cause full or partial combustion of the tobacco or other ingredients. Additionally, charcoal may generate harmful or potentially harmful products, such as carbon monoxide, which may mix with the shisha vapor and pass through the water basin to the outlet.

[0005] One way to reduce the production of carbon monoxide and combustion by-products is to employ e-liquids rather than tobacco. Shisha devices that employ e-liquids eliminate combustion by-products but deprive shisha consumers of the traditional tobacco-based experience.

[0006] Other shisha devices have been proposed that employ electric heaters to heat, but not combust, tobacco. Such electrically heated heat-not-burn shisha devices heat the tobacco substrate to a temperature sufficient to produce an aerosol from the substrate without combusting the substrate, and therefore reduce or eliminate by-products associated with combustion of tobacco.

[0007] Shisha devices may employ a cartridge for housing an aerosol-forming substrate. The cartridge may be filled with such aerosol-forming substrate. The aerosol-forming substrate may comprise tobacco, preferably shisha substrate, such as molasses-a mixture of tobacco, water, sugar, and other components, such as glycerine, flavors, etc. The heating system of the electrically heated shisha device heats the contents of the cartridge to generate aerosol, which is conveyed through an airflow path to a user.

[0008] In order to facilitate airflow through the cartridge and the flow of the aerosol from the cartridge, a shisha cartridge may have one or more holes through one or more walls. Prior art cartridges typically have one or more openings on at least one of the walls of the cartridge, such as in one or both of the top and bottom walls. At least some of the holes or openings in the top and bottom walls may be closed by a removable (for example, peelable) sealing layer, such as a film, sticker, or liner, during storage. The removable layer may protect the contents (for example, the molasses) from exposure to air and oxygen. The removable layer may be removed (for example, pulled or peeled off) by a user prior to first use of the cartridge.

[0009] After use of the shisha device, the cartridge may be removed and discarded. However, the cartridge may still contain material, such as used aerosol-forming substrate. The cartridge may also still be hot if it has not had time to cool down. According to embodiments of the present disclosure, a system is provided for removing and discarding the cartridge.

The cap may advantageously be used to grip the cartridge and to remove the cartridge from the receptacle. This allows a user to remove the cartridge without having to come directly into contact with the used cartridge. The cap with grip member may be used with a disposal vessel. This allows a user to discard the cartridge without having to come directly into contact with the used cartridge. The devices and systems of the present disclosure may help avoid direct contact with a hot cartridge. The devices and systems of the present disclosure may also help prevent leaks and messes from an open cartridge.

[0039] The cap may comprise an outer frame. The outer frame may have any suitable shape. In some embodiments, the outer frame is formed by a cylindrical outer wall extending between a first end wall and an open second end. The first end wall may be a top wall. The outer frame may be open at the bottom. The outer frame may define a cavity for housing the grip member. The cap and grip member may define a longitudinal axis. The longitudinal axis may be a center axis. The longitudinal axis may be coaxial with the hollow tube of the stem pipe.

[0040] According to an embodiment, the cap comprises a grip member configured to grip the cartridge. The grip member may include a ring member and one or more grip fingers extending from the ring member. The one or more grip fingers may be configured to abut against a flange of the cartridge.

[0042] According to an embodiment, the cap includes an outer shroud defining a cavity. The outer shroud may comprise a cylindrical outer wall extending between a first end wall and an open second end. The outer shroud may define a cavity for housing an inner shroud.

[0043] According to an embodiment, the cap includes an inner shroud. The inner shroud may be constructed to at least partially fit within the cavity of the outer shroud. The inner shroud may have an outer wall comprising a first part and a second part. The first and second parts may be cylindrical elements with different diameters. The first part may be a cylindrical wall with a first diameter, and the second part may be a cylindrical wall with a second diameter. The second diameter may be greater than the first diameter. The second part may be coaxial with and below the first part such that a shoulder is formed at the transition between the first and second parts. The shoulder may support a compression spring. The compression spring may fit around the first part. The compression spring may extend from the shoulder to the first end wall of the outer shroud.

[0044] The outer wall of the inner shroud may extend between a first end wall and an open second end. The inner shroud may define a cavity for receiving the cartridge and for housing the grip member.

[0045] The grip member may be disposed inside a cavity of the cap. In some embodiments, the grip member is positioned within the inner shroud. The grip member may be oriented with the one or more grip fingers pointing upward from the ring member. The one or more grip fingers may be slanted radially inward toward the longitudinal (center) axis. When a cartridge is received in the inner shroud, the ring member may circumscribe the cartridge body. The one or more grip fingers may be configured such that the ends of the grip fingers abut against an upper flange of the cartridge. The one or more grip fingers may have a length that is less than the height of the cartridge. The inside diameter of the ring member may be greater than the greatest diameter of the cartridge. When the cap is removed from the aerosol-generating device, the cartridge is removed (for example, lifted up) with the cap due to the grip fingers abutting against the flange, and thus preventing the cartridge from falling out of the cavity.

[0046] The cap may optionally include a piercing assembly (for example, a top piercing assembly). The cap may include an outer shroud and a piercing element on the inside wall of the outer shroud. The piercing element may extend axially downward inside the cavity of the outer shroud. The piercing element may be oriented toward a cartridge placed within a receptacle of the shisha device. The piercing element may be integral with the outer shroud or may be attached to the inside of the first end wall of the outer shroud.

[0047] The inner shroud may have an opening at its first end wall. The opening may be configured to receive the piercing element. The opening may further include one or more recesses or channels for facilitating airflow through the first end wall of the inner shroud while the piercing element is received in the opening.

[0048] The cap may comprise an outer frame. The outer frame may comprise a protrusion extending into the cavity of the outer frame from the inside of the first end wall. The protrusion may be configured for pressing on the outer shroud. The protrusion may serve to leave a gap between the cap outer frame and the outer shroud.

[0049] The top piercing element may have any suitable shape for piercing a wall of the cartridge. For example, the top piercing element may comprise one or more piercing edges or piercing points. The piercing edges or piercing points are configured to pierce a wall (for example, top wall) of the cartridge. The number of piercing points or edges is not particularly limited. The piercing element may have only a single piercing point or edge. The piercing element may have a plurality of piercing points or edges. For example, the piercing element may have 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, or 8 or more piercing points or edges. The piercing element may have 20 or fewer, 15 or fewer, 12 or fewer, 10 or fewer, or 8 or fewer piercing points or edges. In one embodiment, the piercing element is shaped like an inverted crown with multiple piercing points extending downward. The inverted crown may have from 4 to 10 or from 6 to 8 piercing points or edges.

[0050] The outer and inner shrouds may include a track and pin system to guide the movement of the outer and inner shrouds relative to one another. The outer shroud may be vertically, horizontally, or both vertically and horizontally movable. The inner shroud may be vertically, horizontally, or both vertically and horizontally movable. In one embodiment, the inner shroud defines the track and the outer shroud comprises one or more pins. Alternatively, the track may be defined in the outer shroud and the one or more pins may be on the inner shroud. In one embodiment, the outer shroud comprises one or more pins extending radially inwardly from its cylindrical outer wall. The inner shroud may include one or more tracks corresponding to the one or more pins. The one or more tracks may be disposed on the second (lower) part of the inner shroud. The one or more tracks may define multiple positions of the outer shroud. For example, the one or more tracks may define a first position that is a rest position, a second position that is a piercing position, and a third position that is a use position. When the outer shroud is in the second position, the compression spring biases the outer shroud upward. The one or more tracks may also define a fourth position that is a release position of the cap. The release position may be used to release the cap from the aerosol-generating device. When the outer shroud is in the fourth position, the compression spring biases the outer shroud upward. As the compression spring biases the outer shroud upward, it also biases the cap outer frame upward.

[0051] The outer shroud may be pressed down (for example, by a user pressing on the cap outer frame) from the first position to the second position. In entering the second position, the piercing element engages and pierces the cartridge. When pressure is released from the outer shroud, the compression spring returns the outer shroud upward to a third position. In the third position, an airflow path is open through the openings formed in the cartridge. The airflow path may be open between an exterior of the aerosol-generating device (for example, shisha device) and the vessel. The user may use the aerosol-generating device by drawing on the mouthpiece. To release and remove the cap, the user may again press on the outer shroud (for example, by pressing on the cap outer frame), causing the outer shroud to move to the fourth position. From the fourth position, the compression spring returns the outer shroud to the initial first position (the rest position). In this position, the top of the cap may extend above the top edge of the aerosol-generating element and can be gripped by a user. While the cap outer frame and the outer shroud move between the various positions, the cartridge may remain gripped by the grip member in at least some of the positions. The cartridge remains gripped by the grip member at least in the cap release position where the cap may be released from the aerosol-generating device.

[0052] The bottom of the cap outer frame may be attached to a support plate. The support plate may be configured to hold the various parts (for example, grip member, outer shroud, and inner shroud) inside the cavity of the outer frame. The support plate may be a substantially round plate with a center hole extending through the plate. The hole may be sized to accommodate the cartridge. The hole may also be sized to accept the receptacle that may house the cartridge. The hole may have an angled inner edge tapered inward at its upper side. The angled inner edge may aid in engaging the cap with the aerosol-generating element and receiving the cartridge in the cap. The support plate may be attached in any suitable manner, such as by an adhesive or by a coupling element, such as screws, clips, a threaded coupling, snap fit, or friction fit.

[0053] The various parts of the cap and the grip member may be made from any suitable material. Suitable materials include plastic, metal, ceramic, glass, and combinations thereof. Different parts of the system may be made from different materials. For example, some parts, such as the outer shroud and inner shroud may be made of plastic, while other parts, such as the spring may be made of metal. Other combinations are possible. The grip member is preferably made from a material that is capable of flexing. For example, the grip member may be made from metal, plastic, or a combination thereof.

[0054] The shisha device may also optionally include a piercing assembly (for example, a bottom piercing assembly). The bottom piercing assembly may be disposed at the upper end of the stem pipe, below the cartridge. The bottom piercing assembly may extend from the base of the receptacle into the receptacle in a direction away from the base of the receptacle (for example, upward). When the cap is pressed down, the cartridge may also be pressed against the bottom piercing assembly. The cap may be pierced by both piercing assemblies. The piercing assemblies may pierce the top and bottom walls of the cartridge.

[0055] The cartridge may be released from the grip member using a release mechanism. The release mechanism may be part of a disposal system. The disposal system may include a cartridge release member. The cartridge release member may be configured to flex the grip fingers radially outwardly. The cartridge release member may be configured to push the grip fingers outward to release the cartridge.

[0068] In some examples, the aerosol-forming substrate is in the form of a suspension. For example, the aerosol-forming substrate may include molasses. As used herein, "molasses" means an aerosol-forming substrate composition comprising about 20 % or more sugar. For example, the molasses may include at least about 25 % by weight sugar, such as at least about 35 % by weight sugar. Typically, the molasses will contain less than about 60 % by weight sugar, such as less than about 50 % by weight sugar.

[0069] Any suitable amount of aerosol-forming substrate (for example, molasses or tobacco substrate) may be disposed in the cavity. In some preferred embodiments, about 3 g to about 25 g of the aerosol-forming substrate is disposed in the cavity.

The cartridge may include up to 15 g, up to 12 g; up to 11 g, or up to 10 g of aerosol-forming substrate. Preferably, from about 7 g to about 13 g of aerosol-forming substrate is disposed in the cavity.

[0070] The aerosol-forming substrate may be provided on or embedded in a thermally stable carrier. The term "thermally stable" is used herein to indicate a material that does not substantially degrade at temperatures to which the substrate is typically heated (e.g., about 150 °C to about 300 °C). The carrier may comprise a thin layer on which the substrate deposited on a first major surface, on second major outer surface, or on both the first and second major surfaces. The carrier may be formed of, for example, a paper, or paper-like material, a non-woven carbon fiber mat, a low mass open mesh metallic screen, or a perforated metallic foil or any other thermally stable polymer matrix. Alternatively, the carrier may take the form of powder, granules, pellets, shreds, spaghettis, strips or sheets. The carrier may be a non-woven fabric or fiber bundle into which tobacco components have been incorporated. The non-woven fabric or fiber bundle may comprise, for example, carbon fibers, natural cellulose fibers, or cellulose-derivative fibers.

[0071] The body of the cartridge may include one or more walls. In some embodiments, the body includes a top wall, a bottom wall, and a sidewall. The sidewall may be cylindrical or frustoconical, extending from the bottom to the top. The body may include one or more parts. For example, the sidewall and the bottom wall may be an integral single part. The sidewall and the bottom wall may be two parts configured to engage one another in any suitable manner. For example, the sidewall and the bottom wall may be configured to engage one another by threaded engagement or interference fit. The sidewall and the bottom wall may be two parts joined together. For example, the sidewall and the bottom wall may be joined together by welding or by an adhesive. The top wall and sidewall may be a single integral part.

For example, the sidewall and the top wall may be joined together by welding or by an adhesive. The top wall, sidewall and bottom wall may all be a single integral part. The top wall, the sidewall, and the bottom wall may be three separate parts configured to engage one another in any suitable manner. For example, the top wall, the sidewall, and the bottom wall may be configured to engage by threaded engagement interference fit, welding, or an adhesive.

[0072] One or more walls of the body may form a heatable wall or surface. As used herein, "heatable wall" and "heatable surface" mean an area of a wall or a surface to which heat may be applied, either directly or indirectly. The heatable wall or surface may function as a heat transfer surface through which heat may be transferred from outside of the body to the cavity or to an internal surface of the cavity.

[0073] Preferably, the body of the cartridge has a length (for example, an axial length along a vertical center axis) of about 15 cm or less. In some embodiments, the body has a length of about 10 cm or less. The body may have an inside diameter of about 1 cm or more. The inside diameter of the body may be about 1.75 cm or more. The cartridge may have a heatable surface area in the cavity from about 25 cm² to about 100 cm², such as from about 70 cm² to about 100 cm². The volume of the cavity may be from about 10 cm³ to about 50 cm³; preferably from about 25 cm³ to about 40 cm³. In some embodiments, the body has a length in a range from about 3.5 cm to about 7 cm. The inside diameter of the body may be from about 1.5 cm to about 4 cm. The body may have a heatable surface area in the cavity from about 30 cm² to about 100 cm², such as from about 70 cm² to about 100 cm². The volume of the cavity may be from about 10 cm³ to about 50 cm³; preferably from about 25 cm³ to about 40 cm³. Preferably, the body is cylindrical or frustoconical.

[0074] The cartridge body may include one or more openings or ventilation holes through one or more walls of the body. The ventilation holes may be inlets, outlets, or both. The ventilation holes may be disposed at the bottom wall, top wall, sides, or a combination thereof, of the cartridge. In some embodiments, the cartridge does not include any preformed openings or ventilation holes. In some embodiments, the cartridge includes preformed openings or ventilation holes only in one wall. For example, the cartridge may include openings or ventilation holes in the bottom wall only. In some embodiments, one or more inlets or one or more outlets are formed in the cartridge walls by the piercing assembly to allow air to flow through the aerosol-forming substrate when the cartridge is used with a shisha device. In some embodiments, one or more inlets and outlets are formed in the cartridge walls by the piercing assembly to allow air to flow through the aerosol-forming substrate when the cartridge is used with a shisha device. In some embodiments, the bottom wall of the cartridge may define one or more openings to form the one or more outlets of the cartridge. Preferably, the one or more inlets and outlets are sized and shaped to provide a suitable resistance to draw (RTD) through the cartridge. In some examples, the RTD through the cartridge, from the inlet or inlets to the outlet or outlets, may be from about 10 mm H₂O to about 50 mm H₂O, preferably from about 20 mm H₂O to about 40 mm H₂O. The RTD of a specimen refers to the static pressure difference between the two ends of the specimen when it is traversed by an air flow under steady conditions in which the volumetric flow is 17.5 milliliters per second at the output end. The RTD of a specimen may be measured using the method set out in ISO Standard 6565:2002.

[0075] The one or more openings, once formed, on the body may cover 5 % or greater, 10 % or greater, 15 % or greater, 20 % or greater, or 25 % or greater of the area of the wall the openings are on. For example, if the openings are on the top wall, the openings may cover at least 5 % of the area of the top wall. The one or more openings on the body may cover 75 % or less, 50 % or less, 40 % or less, or 30 % or less of the area of the wall the openings are on.

[0076] The cartridge may further include a seal or layer covering one or more preformed openings prior to use. The cartridge may include a first removable seal covering the one or more inlets and a second removable seal covering the one or more outlets. The first and second seals are preferably sufficient to prevent air flow through the inlets and outlets to prevent leakage of the contents of the cartridge and to extend shelf life. The seal may comprise a peelable label of sticker, foil, or the like. The seal may comprise a pierceable label of sticker, foil, or the like. The label, sticker, or foil may be affixed to the cartridge in any suitable manner, such as with an adhesive, crimping, welding, or otherwise being joined to the container. The seal may comprise a tab that may be grasped to peel or remove the label, sticker, or foil from the cartridge.

[0077] In some embodiments the cartridge is a shisha cartridge that may be used with any suitable shisha device. Preferably, the shisha device is configured to sufficiently heat the aerosol-forming substrate in the cartridge to form an aerosol from the aerosol-forming substrate but not to combust the aerosol-forming substrate. For example, the shisha device may be configured to heat the aerosol-forming substrate to a temperature in a range from about 150 °C to about 300 °C; more preferably from about 180 °C to about 250 °C or from about 200 °C to about 230 °C.

[0078] The shisha device may include a receptacle for receiving the cartridge. The shisha device may include a heating element configured to contact or to be in proximity to the body of the cartridge when the cartridge is received in the receptacle. The heating element may form at least part of the receptacle. For example, the heating element may form at least a portion of the surface of the receptacle. The shisha cartridge may be configured to transfer heat from the heating element to the aerosol-forming substrate in the cavity by conduction. In some embodiments, the heating element includes an electric heating element. In some embodiments, the heating element includes a resistive heating component. For example, the heating element may include one or more resistive wires or other resistive elements. The resistive wires may be in contact with a thermally conductive material to distribute heat produced over a broader area. Examples of suitable conductive materials include aluminum, copper, zinc, nickel, silver, and combinations thereof. The heating element may form at least a portion of the surface of the receptacle.

[0079] The shisha device may include control electronics operably coupled to the heating element. The control electronics may be configured to control heating of the heating element. The control electronics may be configured to control the temperature to which the aerosol-forming substrate in the cartridge is heated. The control electronics may be provided in any suitable form and may, for example, include a controller or a memory and a controller. The controller may include one or more of an Application Specific Integrated Circuit (ASIC) state machine, a digital signal processor, a gate array, a microprocessor, or equivalent discrete or integrated logic circuitry. Control electronics may include memory that contains instructions that cause one or more components of the circuitry to carry out a function or aspect of the control electronics. Functions attributable to control electronics in this disclosure may be embodied as one or more of software, firmware, and hardware.

[0080] The electronic circuitry may include a microprocessor, which may be a programmable microprocessor. The electronic circuitry may be configured to regulate a supply of power. The power may be supplied to the heater element in the form of pulses of electrical current.

[0081] In some examples, the control electronics may be configured to monitor the electrical resistance of the heating element and to control the supply of power to the heating element depending on the electrical resistance of the heating element. In this manner, the control electronics may regulate the temperature of the resistive element.

[0082] The shisha device may include a temperature sensor, such as a thermocouple. The temperature sensor may be operably coupled to the control electronics to control the temperature of the heating element. The temperature sensor may be positioned in any suitable location. For example, the temperature sensor may be configured to insert into the cartridge when received within the receptacle to monitor the temperature of the aerosol-forming substrate being heated. In addition or alternatively, the temperature sensor may be in contact with the heating element. In addition or alternatively, the temperature sensor may be positioned to detect temperature at an aerosol outlet of the shisha device or a portion thereof. The sensor may transmit signals regarding the sensed temperature to the control electronics. The control electronics may adjust heating of the heating elements in response to the signal to achieve a suitable temperature at the sensor.

[0083] The control electronics may be operably coupled to a power supply. The shisha device may include any suitable power supply. For example, a power supply of a shisha device may be a battery or set of batteries. The batteries of the power supply may be rechargeable, removable and replaceable, or rechargeable and removable and replaceable. Any suitable battery may be used. For example, heavy duty type or standard batteries existing in the market, such as used for industrial heavy-duty electrical power-tools. Alternatively, the power supply may be any type of electric power supply including a super or hyper-capacitor. Alternatively, the assembly may be connected to an external electrical power source, and electrically and electronically designed for such purpose. Regardless of the type of power supply employed, the power supply preferably provides sufficient energy for the normal functioning of the assembly for at least one shisha session until aerosol is depleted from the aerosol-forming substrate in the cartridge before being recharged or needing to connect to an external electrical power source. Preferably, the power supply provides sufficient energy for the normal functioning of the assembly for at least about 70 minutes of continuous operation of the device, before being recharged or needing to connect to an external electrical power source.

[0084] In one example, a shisha device includes an aerosol-generating element that includes a cartridge receptacle, a heating element, an aerosol outlet, and an air inlet. The cartridge receptacle is configured to receive a cartridge according to the present disclosure containing the aerosol-forming substrate. The heating element may define at least part of a surface of the receptacle.

[0085] The shisha device includes an air inlet channel in fluid connection with the receptacle. In use, when the substrate inside the cartridge is heated, aerosol former components in the substrate vaporize. Air flowing from the air inlet channel through the cartridge becomes entrained with aerosol generated from the aerosol former components in the cartridge.

[0086] Some electrically heated shisha devices employ pre-heated air and typically employ an airflow path such that the air travels in the vicinity of the heat source upon puffing. Further, some electrically heated shisha devices employ elements that increase radiation heat transfer by increasing the heated surface area.

[0087] The air inlet channel may include one or more apertures through the cartridge receptacle such that air from outside the shisha device may flow through the channel and into the cartridge receptacle through the one or more apertures. If a channel includes more than one aperture, the channel may include a manifold to direct air flowing through the channel to each aperture. Preferably, the shisha device includes two or more air inlet channels.

[0088] As described above, the cartridge includes one or more openings (such as inlets or outlets) formed in the body, allowing air to flow through the cartridge. If the receptacle includes one or more inlet apertures, at least some of the inlets in the cartridge may align with the apertures in the top of the receptacle. The cartridge may include an alignment feature configured to mate with a complementary alignment feature of the receptacle to align the inlets of the cartridge with the apertures of the receptacle when the cartridge is inserted into the receptacle.

[0089] Air that enters the cartridge may flow across or through, or both across and through the aerosol-forming substrate, entraining aerosol, and exiting the cartridge and receptacle via an aerosol outlet. From the aerosol outlet, the air carrying the aerosol enters a vessel of the shisha device via the stem pipe.

[0090] The shisha device may include any suitable vessel defining an interior volume configured to contain a liquid and defining an outlet in the headspace above a liquid fill level. The vessel may include an optically transparent or opaque housing to allow a consumer to observe contents contained in the vessel. The vessel may include a liquid fill demarcation, such as a liquid fill line. The vessel housing may be formed of any suitable material. For example, the vessel housing may include glass or suitable rigid plastic material. Preferably, the vessel is removable from a portion of the shisha assembly comprising the aerosol-generation element to allow a consumer to fill, empty or clean the vessel.

[0091] The vessel may be filled to a liquid fill level by a consumer. The liquid preferably includes water, which may optionally be infused with one or more colorants, flavorants, or colorants and flavorants. For example, the water may be infused with one or both of botanical and herbal infusions.

[0092] Aerosol entrained in air exiting the aerosol outlet of the receptacle may travel through a conduit positioned in the vessel. The conduit may be coupled to the aerosol outlet of the aerosol-generating element and may have an opening below the liquid fill level of the vessel, such that aerosol flowing through the vessel flows through the opening of the conduit, then through the liquid, into headspace of the vessel and exits through a headspace outlet, for delivery to a consumer.

[0093] The headspace outlet may be coupled to a hose comprising a mouthpiece for delivering the aerosol to a consumer. The mouthpiece may include an activation element, such as a switch activatable by a user, a puff sensor arranged to detect a user puffing on the mouthpiece, or both a switch activatable by the user and a puff sensor. The activation element is operably coupled to the control electronics of the shisha device. The activation element may be wirelessly coupled to the control electronics. Activation of the activation element may cause the control electronics to activate the heating element, rather than constantly supplying energy to the heating element. Accordingly, the use of an activation element may serve to save energy relative to devices not employing such elements to provide on-demand heating rather than constant heating.

[0094] For purposes of example, one method for using a shisha device as described herein is provided below in chronological order. The vessel may be detached from other components of the shisha device and filled with water. One or more of natural fruit juices, botanicals, and herbal infusions may be added to the water for flavoring. The amount of liquid added should cover a portion of the conduit but should not exceed a fill level mark that may optionally exist on the vessel. The vessel is then reassembled to the shisha device. The cartridge may be placed into the receptacle. The cap may be placed onto the receptacle and cartridge such that the cartridge is received in the cavity inside the cap. The grip member grips the cartridge as the grip fingers slide below the top of the cartridge. The user may press the cap down against the cartridge such that the piercing element (for example, the top piercing assembly, the bottom piercing assembly, or both the top and bottom piercing assemblies) engages the cartridge to pierce one or more walls of the cartridge. The device may then be turned on. Turning on the device may initiate a heating profile of a heating element, to heat the aerosol-forming substrate to a temperature at or above a vaporization temperature but below a combustion temperature of the aerosol-forming substrate. The aerosol forming compounds of the aerosol-forming substrate vaporize, generating an aerosol. The user may puff on the mouthpiece as desired. The user may continue using the device as long as desired or until no more aerosol is visible or being delivered. In some embodiments, the device may be arranged to automatically shut off when the cartridge or a compartment of the cartridge is depleted of usable aerosol-forming substrate. The user may press on the cap to release the cap. The top of the cap may rise above the top level of the aerosol-generating element's body, allowing the user to grip the top of the cap. The user may remove the cap, removing also the cartridge that is gripped by the grip member. In some embodiments, the consumer may refill the device with a fresh cartridge after, for example, receiving the cue from the device that the aerosol-forming substrate in the cartridge is depleted or nearly depleted. The shisha device may be turned off at any time by a consumer by, for example, switching off the device. The user may discard the cartridge by contacting the grip member with a release member of a disposal device, or by actuating a release mechanism on the cap.

[0095] The shisha device may have any suitable air management. In one example, puffing action from the user will create a suction effect causing a low pressure inside the device which will cause external air to flow through an air inlet of the device, into the air inlet channel, and into the receptacle. The air may then flow through the cartridge in the receptacle and become entrained with aerosol produced from the aerosol-forming substrate. The air with entrained aerosol then exits the aerosol outlet of the receptacle, flows through the conduit to the liquid inside the vessel. The aerosol will then bubble out of the liquid and into head space in the vessel above the level of the liquid, out the headspace outlet, and through the hose and mouthpiece for delivery to the consumer. The flow of external air and the flow of the aerosol inside the shisha device may be driven by the action of puffing from the user.

[0097] FIG. 1 is a schematic sectional view of an example of a shisha device 100. The device 100 includes a vessel 17 defining an interior volume configured to contain liquid 19 and defining a headspace outlet 15 above a fill level for the liquid 19. The liquid 19 preferably includes water, which may optionally be infused with one or more colorants, one or more flavorants, or one or more colorants and one or more flavorants. For example, the water may be infused with one or both of botanical infusions and herbal infusions.

[0098] The device 100 also includes an aerosol-generating element 130. The aerosol-generating element 130 includes a receptacle 140 configured to receive a cartridge 200 comprising an aerosol-forming substrate. The aerosol-generating element 130 may also include a heating element 160. The heating element 160 may form at least one surface of the receptacle 140. In the depicted embodiment, the heating element 160 defines the side surfaces of the receptacle 140. The aerosol-generating element 130 also includes an air inlet channel 170 that draws air into the device 100. In some embodiments, portion of the air inlet channel 170 is formed by the heating element 160 to heat the air before the air enters the receptacle 140. The pre-heated air then enters the cartridge 200, which is also heated by heating element 160, to carry aerosol generated by the aerosol former and the aerosol-forming substrate. The air exits an outlet of the aerosol-generating element 130 and enters a conduit 190.

[0099] The conduit 190 carries the air and aerosol into the vessel 17 below the level of the liquid 19. The air and aerosol may bubble through the liquid 19 and exit the headspace outlet 15 of the vessel 17. A hose 20 may be attached to the headspace outlet 15 to carry the aerosol to the mouth of a user. A mouthpiece 25 may be attached to, or form a part of, the hose 20.

[0100] An exemplary air flow path of the device, in use, is depicted by thick arrows in FIG. 1.

[0101] The mouthpiece 25 may include an activation element 27. The activation element 27 may be a switch, button or the like, or may be a puff sensor or the like. The activation element 27 may be placed at any other suitable location of the device 100. The activation element 27 may be in wireless communication with the control electronics 30 to place the device 100 in condition for use or to cause control electronics to activate the heating element 160; for example, by causing power supply 35 to energize the heating element 160.

[0102] The control electronics 30 and power supply 35 may be located in any suitable position of the aerosol-generating element 130, including locations other than the bottom portion of the element 130 as depicted in FIG. 1.

[0103] Referring now to FIGS. 2A and 2B, various embodiments of the cartridge body 210 are shown. The body 210 may include a side wall 212, a top wall 215, and a bottom wall 213 defining a cavity 218. The side wall 212 may be cylindrical or frustoconical, as shown. FIG. 2A shows the body 210 with a portion of the top 215 removed, showing the cavity 218 inside the body. The body 210 may define a center axis A extending through the body 210. The top may comprise a flange 219 that extends from the sidewall 212 as shown in FIG. 2B.

[0104] Referring now to FIGS. 3A and 3B, one or both of the top 215 and bottom 213 of the body may have a plurality of apertures 217, 216 to allow air flow through the cartridge when the cartridge is in use. Some or all of the apertures 217, 216 may be formed by a piercing assembly. For example, the apertures 217 of the top 215 may be formed by a top piercing assembly 401. The apertures 216 of the bottom 213 may be formed by a bottom piercing assembly 301. The cartridge 200 may also or alternatively include apertures along the sidewall 212.

The one or more grip fingers may be configured to abut against the flange 219 of the cartridge 200 when the cartridge 200 is received in the receptacle and the cap 400 is placed over the cartridge 200.

[0106] The cap 400 may optionally include a piercing assembly 401 (for example, a top piercing assembly). The cap 400 may include an outer shroud 420 and a piercing element 440 on the inside wall of the outer shroud 420. In some embodiments, such as those illustrated for example, the piercing element 440 may be disposed on the inside end wall 421. The piercing assembly 401 may further include an inner shroud 430 at least partially disposed within the outer shroud. The piercing element 440 may be oriented toward a cartridge 200 placed within a receptacle of the shisha device 100. The shisha device 100 may also optionally include a piercing assembly 301 (for example, a bottom piercing assembly) at the upstream end of the stem pipe 190.

[0107] An example of a cap 400 and grip member 450 is shown in FIGS. 5A and 5B. Detailed views of each of the elements of the cap 400 and grip member 450 are shown in FIGS. 6-11. The cap 400 and grip member 450 may define a longitudinal axis A. The longitudinal axis A may be a center axis. When the cap 400 is arranged on the shisha device 100, the longitudinal axis A may be coaxial with the hollow tube of the stem pipe 190.

[0108] The cap outer frame 410, shown in FIG. 6, may comprise a cylindrical outer wall 413 extending between a first end wall 411 and an open second end 412. The outer frame 410 may define a cavity 419 for housing the piercing assembly 401. The first end wall 411 may have a protrusion 414 extending from the inside wall.

The end of the compression spring 470 may be supported on the shoulder 435, so that the spring may be compressed against the shoulder 435. The outer wall of the inner shroud 430 may extend between a first end wall 431 and an open second end 432. The inner shroud 430 may define a cavity 439 for housing the grip member 450 and for receiving a cartridge 200. The inner shroud 430 may have an opening 437 at the first end wall 431. The opening 437 may be configured to receive the piercing element 440. The opening 437 may further include one or more channels 438 for facilitating airflow through the inner shroud 430 while the piercing element 440 is received in the opening 437.

[0113] The outer frame 410 may optionally include screw holes 462 configured for fastening a support plate 460 (FIG. 10) to the bottom of the outer frame 410. Alternatively, the support plate 460 may be fastened by other means, such as by an adhesive. The support plate 460 may be a substantially round plate with a center hole 461 extending through the plate. The support plate 410 may be sized to hold the outer and inner shrouds 420, 430 inside the cavity 419 of the outer frame 410, as shown in FIG. 5A. The support plate 410 may also hold the grip member 450 inside the cavity 419 of the outer frame 410.

[0114] The outer and inner shrouds 420, 430 may include a track and pin system to guide the movement of the outer and inner shrouds 420, 430 relative to one another. The outer shroud 420 may comprise one or more pins 425 extending radially inwardly from its cylindrical outer wall 423. The inner shroud 430 may include one or more tracks 436 corresponding to the one or more pins 425. An exemplary track 436 and the path guided by the track 436 are shown in FIGS. 13A-13D. The positions of the track 436 and pin 425 may define the relative positions of the outer and inner shrouds 420, 430. At first, the cap outer frame 410 and the outer shroud 420 are in a first position P1. That is, the pin 425 is in the first position P1 within the track 436. The first position P1 may be considered a rest position. The guide track may comprise a first portion and a second portion. The guide track may comprise a second position P2, which may be a piercing position of the piercing element. The first portion may define a first distance between the first position P1 and a second position P2. The first portion may define a third position P3. The third position P3 may be a use position. The second portion may define a second distance between the third position P3 and a fourth position P4. The second distance may be shorter than the first distance. The first portion may guide the track pin in an axial direction and in a radial direction.

[0115] In the first position P1, the grip member 450 engages the cartridge 200. For example, the upper ends 453 of the grip fingers 452 may slide past (below) the flange 219 of the cartridge when the cap is placed into the first position P1. Alternatively, the grip member 450 may engage the cartridge 200 later as the cap 400 is pushed down. A force may be applied to the cap outer frame 410 and the outer shroud 420, for example, the cap 400 may be pressed down (for example, by a user) to move the pin from the first position to the second position P2 (see arrow in FIG. 13A). In the second position P2, the piercing element 440 may also engage and pierce the cartridge 200. When force is removed, for example when pressure is released from (for example, the user lets go of) the cap outer frame 410 and the outer shroud 420, the compression spring 470 returns the cap outer frame 410 and the outer shroud 420 up to a third position P3. The movement of the cap during the initial pushing down of the cap to pierce the cartridge and the release of the cap to allow the cap to return to the third (use) position is defined by the first portion of the track. In the third position P3, the grip member 450 remains engaged with the cartridge 200. In the third position P3, an airflow path is open through the openings formed in the cartridge 200, and is open between an exterior of the shisha device and the vessel. To release and remove the cap 400, the user may again press on the cap outer frame 410, causing the cap outer frame 410 and the outer shroud 420 to move to a fourth position P4, from where the compression spring 470 returns the cap outer frame 410 and the outer shroud 420 to the initial first position P1. The movement of the cap during the second instance of pushing down of the cap to release the cap is defined by the second portion of the track. When the cap returns to the first position P1, the grip member 450 remains engaged with the cartridge 200, lifting the cartridge 200 upward with the cap. The top of the cap 400 may be raised above the top edge of the aerosol-generating element. The user may then remove (for example, lift) the cap from the aerosol-generating element, thus removing the cartridge 200 with the cap.

[0116] In some embodiments, a disposal system 600, shown in FIGS. 14A and 14B, may be used with the shisha device 100 and the cap 400. The disposal system 600 may be used to remove and optionally dispose of the cartridge 200. The disposal system 600 may comprise a cartridge disposal device 601. The cartridge disposal device 601 may comprise a cartridge release member 610. The cartridge release member 610 may be a pressure ring. The cartridge release member 610 may be constructed to mate with the grip member 450. The cartridge release member 610 (for example, a pressure ring or rim) may have a diameter D610 that is smaller than an inside diameter D451 of the ring member 451 of the grip member 450, but larger than the greatest diameter of the cartridge 200.

[0117] The grip fingers 452 of the grip member 450 may be biased toward a default position. Contacting the grip member 450 with the cartridge release member 610 may push the grip fingers 452 outward, away from the default position. Contacting the grip member 450 with the cartridge release member 610 may comprise engaging the cartridge release member 610 between the cartridge 200 and the ring member 451 of the grip member 450 to flex the one or more grip fingers 452, releasing the cartridge 200 from the grip member 450.

[0118] The disposal system 600 may comprise a disposal vessel 620 with an opening 621. The shape of the disposal vessel 620 is not particularly limited, and is shown in dashed lines. The cartridge release member 610 may be disposed at the opening 621. In some embodiments, the cartridge release member 610 comprises a rim or mouth of the opening 621. Contacting the grip member 450 with the cartridge release member 610 may comprise engaging the rim of the cartridge disposal device 601 between the cartridge 200 and the ring member 451 of the grip member 450.

[0119] The operation of the shisha device 100 and the cap 400 and the removal of the cartridge 200 using a disposal system 600 are schematically shown in FIG. 15. The shisha device 100 includes an aerosol-generating element 130 with a receptacle 140 configured to receive a cartridge 200 comprising an aerosol-forming substrate. The aerosol-generating element 130 may also include a heating element 160. The heating element 160 may form a part of the receptacle 140. A user may begin by placing the cartridge 200 in the receptacle 140 (step 1) and placing the cap 400 onto the cartridge 200 (step 2) such that the cartridge 200 is received in the inner shroud 430 and the grip member 450 slides past the top of the cartridge 200 such that the grip fingers 452 grip the cartridge 200. If the cap includes a piercing assembly, the user may push on the cap to pierce the cartridge 200 (step 3). After letting go of the cap 400, the spring 470 pushes the cap frame 410 and outer shroud 420 up into the operating position (step 4). In the operating position, the air path through the cartridge 200 is open, and the user may use the shisha device as usual. The grip member 450 remains engaged with the cartridge 200. After using the shisha device, the user may push on the cap 400 again to release the cap (step 5). The track-and-pin system will guide the motion of the cap 400, allowing the spring 470 to return the cap 400 to its beginning position (step 6). The grip member 450 remains engaged with the cartridge 200, lifting the cartridge 200 upward with the cap 400. The user may then remove the cap 400 from the device (step 7). The cartridge 200 is held in the inner shroud 430 by the grip member 450. The cartridge 200 may be removed by contacting the grip member 450 with a cartridge release member 610 of a cartridge disposal device 601 (step 8). The cartridge release member 610 may be configured to flex the grip fingers 452. The cartridge release member 610 may be configured to push the grip fingers 452 radially outward to release the cartridge 200.

[0120] Alternatively, the cartridge 200 may be removed by actuating a release mechanism on the cap 400 that causes the grip fingers 452 to release the cartridge 200.

[0121] Thus, systems for gripping and releasing cartridges for shisha devices are described. Various modifications and variations of the invention will be apparent to those skilled in the art without departing from the scope of the invention.

[0122] The cartridge 200 may be removed by contacting the grip member 450 with a cartridge release member 610 of a cartridge disposal device 601 (step 8).
