Description

Technical Field

[0001] The present invention relates to an inhalation device. More specifically, it relates to a foam inhalation device, particularly a battery-operated foam inhalation device (apparatus). Furthermore, the present invention also relates to a foam inhalation device that allows a user to inhale foam, and is also related to a substitute or alternative for tobacco. It is also related to a non-electric inhalation cartridge, and a method and an inhalation device for increasing the duration of an inhalation activity. The device according to the present invention is described as an inhalation device, but it may also be considered as a food or beverage utensil.

Background Art

[0002] Inhalation devices are typically for a user to inhale or ingest a substance or compound. Such substances can bring various effects to the user, such as a medicinal effect, a therapeutic effect, a stimulating effect, a relaxing effect, or a pleasurable effect. For example, a user may inhale a drug or a tobacco component such as nicotine.

[0003] Conventional techniques for consuming or inhaling a compound such as nicotine rely on burning tobacco and directly inhaling the smoke generated therefrom, such as in a cigarette, or inhaling the smoke that has passed through water, such as in a shisha or hookah. However, due to health concerns regarding the inhalation of smoke, there is a need for a substitute for smokers to inhale a compound.

[0004] Typical substitutes include vaporizers and e-cigarettes. These are devices that heat a substance to generate vapor. However, health concerns have been pointed out regarding vaporizers.

[0005] Medical inhalers are well-known. However, such inhalers rapidly push an aerosol into the user's respiratory system, and thus provide a completely different experience from the smoking behavior that is gradually repeated over a long period by the user inhaling through the device.

[0006] Therefore, it is desirable to provide a means of producing a substance for consumption or ingestion that does not require the use of a vaporizer or combustion and can be inhaled through the user's breath over a long period of time. Such alternative means can find applications not only in the food and beverage industry but also in the pharmaceutical, health, and sports fields.

[0007] The present invention aims to provide solutions to these problems.

[0008] According to a first aspect of the present invention, a battery-operated foam inhalation device is provided, comprising: a cartridge having a liquid for generating foam and a foam outlet for the cartridge; a stirring means (comprising an electric motor and a battery for energizing the electric motor) for stirring the liquid to generate foam; a carrier having a receiving section for receiving the cartridge, a carrier foam inlet for fluid communication with the foam outlet of the cartridge when the cartridge is received in the receiving section, a carrier foam outlet for distributing foam to the user, and a conduit between the carrier foam inlet and the carrier foam outlet.

[0009] This device allows users to inhale foam into their mouths and consume it. Because the foam has a long lifespan (is stable), users can inhale it for extended periods. Since it can be consumed in a similar manner to cigarettes, it serves as a substitute or alternative to cigarettes. The foam may be electrically or mechanically generated by a stirring mechanism. This allows users to repeatedly and control the generation of foam as needed.

[0010] Preferably, the device may further include a check valve (one-way valve) to allow the movement of foam from the cartridge foam outlet to the carrier foam outlet and to prevent or restrict the movement of fluid from the carrier foam outlet to the cartridge foam outlet. This prevents or limits the disturbance of the foam inside the device when the user blows back.

[0011] Advantageously, the device may further include a pressure sensor for detecting when negative pressure is applied to the carrier foam outlet.

[0012] As a beneficial configuration, a pressure sensor may be communicatively connected to the stirring means to activate the stirring means to agitate the liquid and generate foam when it detects negative pressure. This allows for easy foam generation. Furthermore, since the user does not need to press, for example, another button to operate the stirring means, it may provide a user experience similar to conventional smoking.

[0013] In a preferred embodiment, the carrier may further include a carrier air inlet. The carrier air inlet may be configured to draw in air from outside the device to help generate bubbles.

[0014] Optionally, the cartridge may include a cartridge air inlet, the carrier may include an air conduit from the carrier air inlet for connection to the cartridge air inlet, and the agitation means may include an air transfer means driven by an electric motor for moving air from the air inlet to the cartridge. Such an arrangement allows air to be moved from outside the apparatus to the cartridge for mixing with the foam-generating liquid.

[0015] Furthermore, the air transport means may consist of an air pump.

[0016] Preferably, the cartridge includes an air injection conduit extending from the cartridge air inlet into the interior of the cartridge, and air may be injected into the cartridge through at least one opening of the air injection conduit. This allows liquid located away from the cartridge air inlet to come into contact with air, thereby improving foam formation. This also prevents or limits the amount of unmixed liquid remaining in the cartridge.

[0017] In this example, the air injection conduit is either attached to the cartridge or is part of the cartridge. However, it should be understood that it may actually be part of the carrier and extend into the cartridge through the cartridge air intake.

[0018] Preferably, the air injection conduit may have multiple openings. More openings allow more liquid to be exposed to the air, which can speed up foam formation.

[0019] Furthermore, there may be at least five openings.

[0020] Preferably, the air injection conduit is elongated, and multiple openings may be spaced apart along its longitudinal range. This may allow for more uniform bubble generation.

[0021] Preferably, the at least one opening is located closer to the end of the cartridge opposite the cartridge air inlet than to the cartridge air inlet. This further improves foam generation and further prevents or limits the retention of unmixed liquid in pockets within the cartridge.

[0022] Optionally, the cartridge foam outlet and the cartridge air inlet may each be provided with a seal, at least a portion of the carrier conduit may be configured to perforate the seal of the cartridge foam outlet, and at least a portion of the air conduit may be configured to perforate the seal of the cartridge air inlet. This seal allows the cartridge to remain liquid-tight during transport, and since the conduit is configured to perforate the seal, fluid communication between the cartridge and the conduit can be easily achieved when needed.

[0023] Preferably, the carrier conduit and the air flow conduit protrude from the receiving portion so as to allow for the perforation of the cartridge foam outlet and cartridge air inlet, respectively.

[0024] In a preferred embodiment, each seal is flexible so that it can seal the cartridge foam outlet to the carrier conduit and seal the cartridge air inlet to the air flow conduit. This may prevent leakage from the cartridge.

[0025] Optionally, the apparatus may have a cartridge presence sensor configured to detect that the cartridge is received in the cartridge receiving portion, and the stirring means is configured to operate only when the cartridge presence sensor detects the cartridge in the cartridge receiving portion. In this way, battery consumption can be suppressed by preventing or restricting the unintended operation of the stirring means. Such a sensor is sometimes called a switch.

[0026] Preferably, the liquid may further contain at least one of nicotine, cannabis components, pharmaceuticals, dietary supplements, foods or beverage substances.

[0027] Preferably, the apparatus has an elongated shape with a length of 150 mm or less and a width of 50 mm or less. Such dimensions facilitate holding and using the apparatus and may provide a user experience similar to smoking.

[0028] According to a second aspect of the present invention, there is provided a foam inhalation device for inhaling foam therefrom with the user's breath, the foam inhalation device comprising the following components: A container for containing a liquid for generating foam (having a container foam outlet for discharging foam and a container air inlet for receiving air). Electrically energizable air moving means for moving air from outside the apparatus to the container air inlet. A power source for supplying power to the electrically energizable air moving means. A mouthpiece in fluid communication with the foam outlet so that the user can aspirate the foam. A pressure sensor in fluid communication with the mouthpiece for detecting that a negative pressure has been applied to the mouthpiece. A processor configured to operate the electrically energizable air moving means when the pressure sensor detects that a negative pressure has been applied to the mouthpiece.

[0029] According to a third aspect of the present invention, there is provided a foam inhalation device comprising: a liquid for generating foam, and a cartridge having a cartridge foam outlet; stirring means for stirring the liquid to generate foam; a receiving portion for receiving the cartridge, a carrier foam inlet that is in fluid communication with the cartridge foam outlet when the cartridge is received in the receiving portion, a carrier foam outlet for dispensing foam to a user, a conduit between the carrier foam inlet and the carrier foam outlet, and a carrier having a carrier air inlet.

[0030] According to a fourth aspect of the present invention, there is provided a stable foam inhalation device for discharging stable foam inhaled by a user over a long period of time, the inhalation device comprising: a foam generating element receiving portion; a stable foam generating element for generating the stable foam (the stable foam generating element being receivable in the foam generating element receiving portion and at least one of the components being separated from the other of the components by an openable barrier); an outlet for discharging the stable foam to the user; and a fluid flow path fluidly connecting the foam generating element receiving portion and the outlet (when the barrier is opened, the components interact to generate stable foam, which flows through the fluid flow path to the outlet and is inhaled by the user over a long period of time).

[0031] In contrast to the use of substances that disperse in a short period of time or inhalants that are rapidly inhaled, stable foam allows the user to slowly consume or inhale the substances contained in the foam over a long period of time and with multiple inhalations. This can provide the user with a sense of satisfaction and pleasure. The partitioning member spatially separates the foam generating element from the outlet of the cartridge, thereby allowing the foam to expand into the space therebetween. Such a space is defined by an expansion chamber. The partitioning member maintains the separation between the components and can break the partitioning member to permit the generation of foam when the user attempts to inhale the foam.

[0032] The foam generating element receiving portion may also be referred to as a foam generating element receptacle, port, dock, chamber.

[0033] Preferably, at least one of the stable foam generating elements may be housed in a non-electric inhalation cartridge. A non-electric inhalation cartridge can reduce or eliminate the need for electrical charging. The cartridge provides a convenient way to load the stable foam generating components into the instrument, allowing the rest of the instrument to be reused with additional cartridges.

[0034] As an advantageous configuration, at least one of the stable foam generating elements may be composed of a liquid received in the liquid receiving chamber of a non-electric inhalation cartridge.

[0035] A favorable configuration may be one in which the liquid is discharged from the liquid receiving chamber by manual pressure applied to the chamber. Manual operation is convenient and eliminates or minimizes the need for complex mechanisms.

[0036] In a preferred embodiment, at least one of the stable foam generating elements may include a solid that is received in a solid receiving chamber of a non-electric suction cartridge.

[0037] Furthermore, a retractable barrier may be provided between the solid receiving chamber and the liquid receiving chamber.

[0038] Preferably, there may be two stable foam-generating elements, each receiving a stable foam-generating element in a separate chamber, with one chamber located on the path between the other chamber and the outlet, so that the stable foam-generating elements are mixed in the other chamber. This promotes the mixing of the stable foam-generating elements, reduces the amount of unreacted material, and consequently reduces waste.

[0039] In an advantageous configuration, the cartridge may further include an openable / closable barrier at or adjacent to its end, which is capable of fluid communication with the fluid channel, allowing foam, or at least one stable foam-generating element, to flow into the fluid channel when the openable / closable barrier is opened. When the cartridge is not inserted into the carrier, the presence of an additional barrier may help contain the stable foam component.

[0040] For a beneficial configuration, each openable barrier may be a flat seal.

[0041] In a preferred embodiment, each openable / closable barrier may be made of foil. Foils such as metal foil provide a high degree of airtightness between components, which can extend the shelf life of the device, while also allowing for easy perforation or opening when needed.

[0042] Optionally, at least a portion of the outlet and fluid passage may be defined by a carrier for a non-electric suction cartridge.

[0043] Preferably, the fluid flow path may include a conduit located at or adjacent to the outlet, and an expansion chamber provided between the foam-generating element receiving section and the conduit. The expansion chamber may provide space for the foam to expand and may allow the foam to be stored for a short period before being drawn in.

[0044] Advantageously, the expansion chamber may be defined by the carrier. In this case, since the expansion chamber is not part of the disposable cartridge, waste is eliminated.

[0045] In a preferred embodiment, the conduit may have an inlet opening that is off-center relative to the expansion chamber. This arrangement allows the suction port to be located at a lower position during use. In this case, as the foam is consumed and the foam level in the expansion chamber decreases, the remaining foam will occupy the lower part of the expansion chamber due to gravity, thus allowing a larger total amount of foam to be utilized.

[0046] Beneficiently, the conduit may have an inlet opening and a longitudinal range that positions the inlet opening closer to the foam-generating element receiving area than the outlet. This allows foam to be drawn in from the end of the cartridge. That is, foam is drawn from a more central region of the expansion chamber to the outlet, which may improve the uniformity of the foam at the outlet.

[0047] Preferably, the device may further include a projection for assisting in the dispensing of one of the stabilizing foam-generating elements. The projection may be pointed and needle-shaped and may assist in puncturing the barrier.

[0048] Furthermore, the projections may be for perforating an openable and closable barrier, and may include passages to allow the passage of foam or stable foam-forming elements. By providing passages such as bores or channels, it is possible to prevent the holes or perforations formed by the projections from being blocked.

[0049] Optionally, the projection may be configured to perforate both openable and closable barriers.

[0050] A favorable configuration may include two protrusions: a second protrusion configured to project into one chamber and a first protrusion configured to project into at least the other chamber. By spacing these protrusions apart, the components can be mixed more efficiently.

[0051] Beneficiently, the device may further include a check valve to allow the movement of foam from the foam-generating element receiving section to the outlet and to prevent or restrict the movement of fluid from the outlet to the foam-generating element receiving section.

[0052] In a preferred embodiment, the stabilizing foam-generating element may contain a carbonate and an acid together. This allows foaming to be produced by generating carbon dioxide through a chemical reaction. The chemical reaction offers greater manufacturing convenience compared to, for example, releasing a pressurized container. While carbonates have been described, more generally, the stabilizing foam component may consist of both a base and an acid. Alternatively, the stabilizing foam-generating element may consist of any chemical gas-generating means, particularly a carbon dioxide-generating means. It should be understood that the stabilizing foam-generating element may, for example, consist of a sugar and a component for converting the sugar into carbon dioxide, such as yeast.

[0053] Additionally, at least one of the carbonate and the acid may be in powder form. Since powders have a larger surface area than other solids, foam may form more quickly.

[0054] Preferably, the barrier can be opened by being destroyed.

[0055] As an advantageous configuration, one of the stable foam generating elements may include a stabilizer.

[0056] Furthermore, one of the foam-stabilizing elements may include a thickening agent.

[0057] A fifth aspect of the present invention provides a method for increasing the duration of inhalation activity, the method comprising the following steps: providing the apparatus described in any of the above; opening a barrier so that a foam-generating element reacts to produce stable foam, which flows through a fluid channel to an outlet; and inhaling the stable foam multiple times.

[0058] According to a sixth aspect of the present invention, a nicotine inhalation device is provided for dispensing stable foam that can be inhaled by a user over a long period of time, the inhalation device having the following configuration: a foam-generating element receiving section; a non-electric inhalation cartridge having stable foam-generating elements for generating stable foam (the components are receivable in a component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the components that generate stable foam contains nicotine); an outlet for providing stable foam to the user; and a fluid channel fluidically connecting the foam-generating element receiving section and the outlet (the components interact to generate stable foam when the barrier is opened, and the foam flows through the fluid channel to the outlet for inhalation by the user over a long period of time).

[0059] According to a seventh aspect of the present invention, a cannabis component inhalation device is provided for dispensing a stable foam that can be inhaled by a user over a long period of time, the inhalation device having the following configuration: a foam-generating element receiving section; a non-electric inhalation cartridge having a stable foam-generating element for generating stable foam (the component is receivable in the component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the stable foam-generating components contains a cannabis component); an outlet for providing stable foam to the user; and a fluid channel fluidically connecting the foam-generating element receiving section and the outlet (the components interact to generate stable foam when the barrier is opened, which flows through the fluid channel to the outlet for inhalation by the user over a long period of time).

[0060] According to an eighth aspect of the present invention, a supplement inhalation device is provided for dispensing stable foam that can be inhaled by a user over a long period of time, the inhalation device comprising: a foam-generating element receiving section; a non-electric inhalation cartridge having stable foam-generating elements for generating stable foam (the components are receivable in a component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the components that generate stable foam includes a supplement); an outlet for providing stable foam to the user; and a fluid channel fluidically connecting the foam-generating element receiving section and the outlet (the components interact to generate stable foam when the barrier is opened, and flow through the fluid channel to the outlet for inhalation by the user over a long period of time).

[0061] According to a ninth aspect of the present invention, a food and beverage inhalation device is provided for dispensing stable foam that can be inhaled by a user over a long period of time, the inhalation device having the following configuration: a foam-generating element receiving section; a non-electric inhalation cartridge having stable foam-generating elements for generating stable foam (the components are receivable in a component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the components that generate stable foam includes food and beverage); an outlet for providing stable foam to the user; and a fluid channel fluidically connecting the foam-generating element receiving section and the outlet (the components interact to generate stable foam when the barrier is opened, and the foam flows through the fluid channel to the outlet for inhalation by the user over a long period of time).

[0062] According to a tenth aspect of the present invention, an inhalation device is provided for dispensing a stable foam that is inhaled by a user over a long period of time, the inhalation device having the following configuration: a foam-generating element receiving section; a non-electric inhalation cartridge having a stable foam-generating element for generating stable foam (the components are receivable in a component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the components that generate stable foam contains an inhalant); an outlet for providing stable foam to the user; and a fluid channel fluidically connecting the foam-generating element receiving section and the outlet (the components interact to generate stable foam when the barrier is opened, and flow through the fluid channel to the outlet for inhalation by the user over a long period of time).

[0063] According to an eleventh aspect of the present invention, a stable foam inhalation device is provided for dispensing a stable foam that is inhaled by a user over a long period of time, the inhalation device having the following configuration: a cartridge receiving section; a cartridge receivable in the cartridge receiving section (including at least one chamber for receiving foam-generating elements and a perforable barrier that is in fluid communication with the chamber); a non-electric inhalation cartridge having a stable foam-generating element for generating stable foam (the components are receivable in a component receiving section, at least one of the components is separated from the other by an openable and closable barrier, and at least one of the components that generate stable foam includes an inhalant); an outlet for providing stable foam to the user; a fluid channel that fluidically connects the foam-generating element receiving section and the outlet (to allow components to interact when the barrier is opened to generate stable foam, which flows through the fluid channel to the outlet for inhalation by the user over a long period of time); and a projection located at or adjacent to the cartridge receiving section for perforating the barrier. A fluid channel that fluidly connects the cartridge receiving portion and the outlet so that the chamber is in fluid communication with the outlet when the barrier is perforated by the projection.

[0064] According to an eleventh aspect of the present invention, a stable foam inhalation device is provided for discharging a stable foam that is inhaled by a user over a long period of time, the inhalation device comprising: a first chamber (containing a liquid foam generating element) having a wall that is at least partially flexible; a second chamber having a further foam generating element; an openable and closable barrier between the first chamber and the second chamber; the flexible wall operable to release the liquid foam generating element from the first chamber to the second chamber so that a stable foam is generated and discharged from the outlet when the barrier is opened.

[0065] According to an eleventh aspect of the present invention, a stable foam inhalation device is provided for dispensing stable foam that is inhaled by a user over a long period of time, the inhalation device comprising: a first chamber (including a liquid foam generating element) having a wall that is at least partially flexible; a second chamber having a further foam generating element; a liquid foam generating element and a further foam generating element that are interactable to generate stable foam; at least one outlet attached to a cartridge for dispensing foam or at least one of the foam generating elements from the cartridge; the flexible wall being operable so that foam or liquid foam generating elements are discharged from the outlet.

[0066] According to a fourteenth aspect of the present invention, a liquid discharge device is provided, the discharge device having the following configuration: a container containing a liquid (at least a portion of the container includes a flexible wall for manually applying pressure to the liquid); a wall including an opening for releasing the liquid from the container when pressure is applied to the liquid by hand, or a perforated portion into which an opening can be formed for releasing the liquid from the container when pressure is applied to the liquid by hand.

[0067] According to a fifteenth aspect of the present invention, a cartridge for a stabilizing foam inhalation device is provided for dispensing stabilizing foam consumed by a user. The cartridge for the inhalation device has no electrical means of conduction and comprises the following elements: a flexible mixing chamber having a first receiving portion for slidingly receiving a first foam-generating element and a second receiving portion for slidingly receiving a second foam-generating element (wherein the flexible mixing chamber, an access opening is located at the first end and closed at the second end opposite to the first end, and the access opening is sized to penetrate and receive the first and second foam-generating elements); and an expansion chamber fluidly communicating with the access opening of the flexible mixing chamber via a partition member (wherein the partition member has one or more mixing members for stirring the consumable foam generated by the first and second foam-generating elements as it passes from the mixing chamber to the expansion chamber). A discharge member located at or adjacent to one end of the expansion chamber and having an outlet to allow the user to inhale ingestible foam from the expansion chamber (where the discharge member includes an inlet opening and a discharge conduit connecting the inlet opening and the discharge outlet, the discharge conduit having a longitudinal range that positions the inlet opening closer to the partition member than the discharge outlet).

[0068] In contrast to substances that dissipate quickly or inhalants that are rapidly inhaled, stable foam allows the user to slowly consume or inhale the substance contained within the foam over a long period and multiple inhalations. This can provide the user with satisfaction and pleasure. Cartridges without electrical elements reduce or eliminate the need for charging. Flexible mixing chambers provide a convenient method, for example, when manually activating the foam-generating element. Partition members spatially separate the foam-generating element from the cartridge outlet, thereby allowing the foam to expand into the space between them. Such a space is defined by the expansion chamber. Mixing members (mixing arms) provided by the partition members define an opening for the foam to move through. The movement of the foam through the opening may generate vortices that help mix the foam with unreacted foam-generating elements to improve the homogeneity of the foam. Outlets with discharge conduits allow the foam to be drawn away from one end of the cartridge. In other words, the foam can be drawn from the central region of the cartridge towards the outlet to improve the homogeneity of the foam at the outlet.

[0069] Although the mixing chamber is described as flexible, it does not necessarily have to be. For example, if a non-manual activation means is considered, or if the mixing chamber and expansion chamber are integrally formed, the mixing chamber may not have an access opening for that purpose.

[0070] The second end of the mixing chamber may be formed integrally with the rest of the mixing chamber, or a detachable end cap may be used.

[0071] Partition members are listed, but they are not essential. Furthermore, even if partition members are present, mixing members are not essential.

[0072] Although a discharge conduit is described in the discharge member, this may be omitted. Alternatively, even if a discharge conduit is present, its longitudinal range may be such that the inlet opening is closer to the outlet opening than to the partition element.

[0073] Although the cartridge is described as lacking an electrical means of supplying power, it may include one. For example, the cartridge may include an electric motor for agitating the liquid to generate foam and a battery for powering the electric motor.

[0074] While the device is described as being for stable foam, it may be used in conjunction with other inhalants or consumables.

[0075] Preferably, the flexible mixing chamber may be made of a thermoplastic elastomer. The thermoplastic elastomer can provide a food-safe, durable, and sufficiently flexible material for the mixing chamber.

[0076] Preferably, the inlet opening may be off-center relative to the expansion chamber. In a preferred embodiment, the inlet opening may be located on or adjacent to the side wall of the expansion chamber. This arrangement allows the inlet opening to be located below the device in use. This allows for the utilization of more foam, as even as foam is consumed and the amount of foam in the expansion chamber decreases, the remaining foam will occupy the lower part of the expansion chamber due to gravity.

[0077] Preferably, the partition member includes a stop, and the access opening and expansion chamber can be connected to the partition member on both sides of the stop. This allows the mixing chamber and expansion chamber to be pressed against the sealing surface of the partition member until they reach the stop, thus facilitating the assembly of the cartridge.

[0078] In a preferred embodiment, the stop may be a raised portion extending around the partition member.

[0079] Preferably, the partition member includes an axially extending projection that extends into the flexible mixing chamber to contact a first or second foam-generating element. This may provide a small area in contact with the first or second foam-generating element, for example, to help drain liquid from there.

[0080] Optionally, the passage through the partition member may widen from the flexible mixing chamber toward the expansion chamber. Widening the passage may encourage the movement of foam from the mixing chamber toward the expansion chamber.

[0081] Furthermore, the passageway may be widened via steps. This could potentially simplify the manufacturing method for widening the passageway.

[0082] Preferably, the cartridge for the inhalation device may further include a first foam-generating element and a second foam-generating element.

[0083] Preferably, the second foam-generating element may include a liquid container. The liquid allows the first foam-generating element to dissolve.

[0084] In a preferred embodiment, the liquid may be water. Water is an ingestible liquid and can be used in a variety of container materials. Other liquids may be used as solvents.

[0085] Furthermore, the liquid may be dispensed from the container via manual pressure applied to the container. This allows the user to conveniently dispense the liquid from the container without tools.

[0086] Optionally, the container may be rupturable via the manual pressure. A fragile (easily burstable, easily crushed) container usually allows for the dispensing of liquid from a sealed container.

[0087] Preferably, the container may include holes in its outer wall that block or restrict the passage of liquid when no manual pressure is applied to the container, and allow the liquid to be discharged when manual pressure is applied to the container. This has the advantage of eliminating the need to break the container to discharge the liquid.

[0088] Preferably, the container may be oriented so that the holes face the first foam-generating element. In this way, the liquid is dispensed directly toward the first foam-generating element, which can reduce or eliminate the need, for example, to shake the cartridge to better distribute the liquid.

[0089] Preferably, the container may be made of a thermoplastic elastomer. Thermoplastic elastomers can provide a food-safe, durable, and sufficiently flexible material.

[0090] Preferably, the first foam-generating element consists of a carbonate and an acid. This enables foaming by generating carbon dioxide through a chemical reaction. The chemical reaction can generate foam more easily than, for example, releasing a pressurized container.

[0091] In a preferred embodiment, the carbonate consists of sodium bicarbonate and the acid consists of citric acid. These two components are highly ingestible and food-safe, but other components may be used.

[0092] Preferably, the first foam-generating element includes a stabilizer. The stabilizer enables the conversion of short-term foam dissipation into stable foam.

[0093] The stabilizers may consist of lectins or xanthan gum. Other stabilizers or thickeners may also be used.

[0094] According to a sixteenth aspect of the present invention, a stable foam inhalation device is provided for dispensing stable foam for a user to ingest. The inhalation device comprises a cartridge and a carrier as described in any one of the preceding paragraphs, the carrier comprising the following elements: a carrier body; a receiving section for receiving a cartridge within the carrier body; a carrier inlet for fluid communication with the outlet of a discharge member when the carrier is received in the receiving section; a carrier outlet for distributing stable foam to the user; and a conduit between the carrier inlet and the carrier outlet, passing through the carrier body.

[0095] By separating the carrier and cartridge, disposable cartridges and reusable carriers can be used. This provides the convenience of a pre-loaded cartridge, even though the entire instrument is not disposable. Furthermore, because the carrier is reusable, it can include additional functions and be designed to be ergonomically sized without significant concerns about material waste.

[0096] The cartridge discharge conduit may extend through at least a portion of the carrier. In practice, the discharge conduit may extend only through the carrier and not necessarily through the expansion chamber.

[0097] Preferably, the stable foam inhalation device may further include a check valve in the conduit to allow the movement of foam from the carrier inlet to the carrier outlet and to prevent or restrict the movement of fluid from the carrier outlet to the carrier inlet. This allows the user to consume or inhale foam while preventing or limiting exhaling into the device and disrupting the foam distribution within the device.

[0098] Preferably, the check valve may be a duckbill valve.

[0099] Preferably, the suction device for stable foam may further include an indicator element to show that foam is being suctioned. This indicates to the user or bystander that the device is in use.

[0100] Furthermore, the display element may include a light-emitting element for illumination when the foam is being inhaled. Illumination is a less intrusive signal compared to, for example, sound. The light-emitting element does not interfere with the primary function of the inhalation device; that is, the user can inhale the foam whether the light is present and working or not.

[0101] Preferably, the display element may include a pressure sensor, which allows the device to detect when the user is inhaling.

[0102] Optionally, the pressure sensor may be independent of the conduit and located in a sub-conduit that can communicate fluidly with the conduit. In this case, the pressure sensor may be located away from the outlet, which may be convenient for the electrical arrangement of the device.

[0103] Preferably, the carrier body includes a receiving portion, where a portion of the carrier body is movable relative to the rest of the carrier body in order to securely hold the cartridge. The size of the receiving portion can be changed by the movable member of the carrier body. In other words, the movable member can be moved to enlarge or extend the receiving portion so that a cartridge can be placed therein. The movable member can then be returned to its predetermined position to secure the cartridge in place.

[0104] Preferably, the stable foam inhalation device may further include biasing means for biasing the portion of the carrier body toward the receiving portion. The biasing means allows the movable portion to automatically retract toward the cartridge and can hold the cartridge in place with bias force. This would be advantageous for users who have difficulty with fine motor skills, such as those with arthritis.

[0105] Preferably, the biasing means may be a spring.

[0106] Optionally, the movable part may be located at or adjacent to the carrier entrance.

[0107] Preferably, the carrier body may include at least one side wall, which may contain an access opening for visual or tactile access to the cartridge. The access opening can, for example, allow the cartridge to be directly engaged and moved. For example, it may allow the foam-generating element to be manually operated through the wall of the mixing chamber. Furthermore, allowing the cartridge to move through the access opening may help to release the cartridge from the receiving section. Alternatively or additionally, the access opening may allow the user to visually inspect the amount or level of foam remaining in the cartridge. Using the access opening allows access to the cartridge, while the side wall extends further upward from the side of the cartridge, allowing the cartridge to be more securely held in place laterally. The access opening also contributes to facilitating removal from the receiving section by applying leverage to the underside of the cartridge.

[0108] Preferably, the carrier body may have two side walls, each side wall having an access opening. The access opening in each side wall allows the cartridge to be grasped between the fingers.

[0109] Preferably, the carrier body and each access opening or each access opening may be elongated, and the longitudinal range of each access opening or each access opening coincides with the longitudinal range of the carrier body. This makes a larger portion of the cartridge visible.

[0110] Furthermore, the access opening may extend toward the biasing means. This may allow the cartridge to be easily moved toward the biasing means.

[0111] In a preferred embodiment, the access opening or each access opening may be tapered.

[0125] First, referring to Figures 1 to 6, the foam intake device (foam extraction device) is equipped with a carrier (672) as shown in Figures 1 to 3, and a cartridge (610) as shown in Figures 4 to 6 is received therein. This device operates electrically, and in this case, it is powered by a battery (760), so it is battery-operated, but please understand that other power sources are also possible.

[0126] The foam is generated by agitating the liquid with an agitator, which includes at least a motor (762) and a battery (760). The agitator is sometimes also called an agitator.

[0127] Referring particularly to Figures 1 to 3, the carrier (672) preferably has a carrier body (676) that houses a motor (762) and a battery (760). The carrier (672) further includes a receiving portion (678) on or within the carrier body (676) for receiving a cartridge (610). Here, the receiving portion (678) is a recess or open-end chamber defined by the carrier body (676) and having a size therefor to receive at least a portion of the cartridge (610). Preferably, the receiving portion (678) receives only a portion of the cartridge (610) therefor, with the end of the cartridge (610) protruding from the end of the receiving portion (678).

[0128] The carrier (672) further includes a carrier foam inlet (680) for receiving foam from the cartridge (610) when the cartridge (610) is received in the receiving section (678). The carrier (672) also includes a carrier foam outlet (682) for discharging foam to the user, as defined by the mouthpiece (764) in this example. A carrier foam conduit (684) (passage, flow path) connects the carrier foam inlet (680) and the carrier foam outlet (682).

[0129] At least one end of the carrier foam conduit (684) adjacent to the carrier foam inlet (680) preferably protrudes into the receiving portion (678) so that the carrier foam conduit (684) can penetrate the cartridge (610). However, this may not be necessary, and the conduit may not protrude and instead be connected adjacent to the cartridge (610).

[0130] The carrier foam conduit (684) may include a chamber (684a) adjacent to the mouthpiece (764). However, it should be understood that this may be omitted.

[0131] A check valve may be present in the carrier foam conduit (684) to allow the movement of foam from the carrier foam inlet (680) to the carrier foam outlet (682) and to prevent or restrict the movement of fluid from the carrier foam outlet (682) to the carrier foam inlet (680).

[0132] Furthermore, the carrier further comprises a carrier air inlet (690) and an air conduit (766) extending from the carrier air inlet (690) and terminating at a carrier air outlet (768) located inside or adjacent to the receiving portion (678). The carrier air inlet (690) is open to the outside of the carrier (672) during use and is separate from the carrier foam outlet (682), preferably located away from the carrier foam outlet (682). For example, the carrier foam outlet 682 is preferably positioned so as not to be covered by the user's mouth when the user is drawing from the carrier foam outlet (682). Preferably, the carrier air inlet (690) is located at the base of the carrier (672). Similar to the carrier foam conduit (684), the air conduit (766) preferably protrudes into the receiving portion (678) to allow penetration into the cartridge (610).

[0133] The air conduit (766) and carrier air outlet (768) are located below the carrier foam conduit (684) and carrier foam inlet (680) during use.

[0134] The stirring means is preferably driven by an electric motor (762) and includes an air moving means for moving air from a carrier air inlet (690) to a carrier air outlet (768). The air moving means may be an air pump (770). For example, the air pump (770) may be a fan or impeller rotatable by the electric motor (762), but may take other forms.

[0135] The apparatus preferably includes a pressure sensor (712), in this example the pressure sensor (712) is housed in a carrier (672). The pressure sensor (712) is in fluid communication with the carrier bubble outlet (682) to detect when negative pressure is applied to the carrier bubble outlet (682). Here, the pressure sensor (712) is located adjacent to or within the chamber (684a) which is in close proximity to the mouthpiece (764).

[0136] The device includes a processor, which in this example is located on or provided by a printed circuit board (772), which is again housed in a carrier (672). A battery (760), a motor (762), and a pressure sensor (712) are connected to the printed circuit board 772. When the pressure sensor (712) detects negative pressure, the processor draws power from the battery (760) to operate the motor (762), which in turn drives the air pump (770).

[0137] The motor (762) is preferably a brushless electric motor.

[0138] The battery (760) may be rechargeable, and for that purpose, a power terminal for enabling charging may be present. Additionally, or alternatively, the battery (760) may be removable from the carrier (672) to allow for replacement. The battery (760) may be replaceable or not rechargeable, in which case it may be necessary to discard the carrier (672) after the battery (760) has been discharged.

[0139] Referring specifically to Figures 4 to 6, the cartridge (610) has a cartridge foam outlet (654) and defines a container for holding liquid to generate foam via agitation.

[0140] The liquid may contain at least one foaming agent, surfactant, stabilizer, thickener, or a combination thereof to enable foam generation by stirring. This may include lectins, xanthan gum, or both. The foaming agent, and the liquid as a whole, should be food-safe to allow human consumption.

[0141] The liquid may contain acids such as citric acid or sodium bicarbonate, carbonates, or both. If acids and carbonates were present in the cartridge, they may have already produced bubbles, carbon dioxide, or both, and the resulting salts, such as sodium citrate, may be present in the cartridge (610) before use of the apparatus. Even while the cartridge (610) is sealed, if carbon dioxide is produced by such reactions, bubbles may spontaneously form when the cartridge (610) is opened, as the pressure decreases and dissolved carbon dioxide is released. However, even in this case, the method of bubble formation is primarily by agitation.

[0142] The cartridge (610) is preferably elongated or substantially tubular. In this example, the cartridge (610) has a flat end containing a cartridge foam outlet (654) and a rounded end opposite the flat end.

[0143] It should be understood that the cartridge (610) may be made of a flexible material to allow manual operation, or it may be made of a rigid material.

[0144] The cartridge (610) preferably also includes a cartridge air inlet (774). The cartridge air inlet (774) is preferably located at or adjacent to the cartridge foam outlet (654), for example, at a flat end, but it should be understood that it may be located elsewhere. The cartridge air inlet (774) is preferably located below the cartridge foam outlet (654) when in use.

[0145] The cartridge (610) preferably has an air injection conduit (776) extending from a cartridge air inlet (774) into the interior (778) of the cartridge (610) for injecting air into the cartridge (610) through at least one opening (780) of the air injection conduit (776). Preferably, the air injection conduit (776) is elongated and has a plurality of openings (780) therein that are spaced apart from each other over the longitudinal range of the air injection conduit (776).

[0146] The air injection conduit (776) may have at least one opening (780) on two opposing sides. Preferably, the openings (780) on both sides are aligned with each other.

[0147] Each opening (780) may be circular. Preferably, there are at least five openings (780), and in this example, there are seven openings (780) on each of the opposing sides of the air injection conduit (776).

[0148] Alternatively, each opening (780) may have the shape of a partial circle or a semicircle. In this case, each side of the air injection conduit (776) may have multiple pairs of openings (780), and each pair of openings (780) is spaced apart from each other in the lateral direction of the conduit. Preferably, there are seven pairs of openings (780) on both sides of the conduit.

[0149] The cartridge air inlet (774) and the cartridge foam outlet (654) are each closed by a perforated or otherwise openable seal. For example, in this example, each of the cartridge air inlet (774) and the cartridge foam outlet (654) has a perforated seal that is also flexible, preferably such as a silicone seal.

[0150] The carrier foam conduit (684) and air flow conduit (766) of the carrier (672) are positioned to perforate the cartridge foam outlet (654) and cartridge air inlet (774), respectively, when the cartridge (610) is received in the receiving section (678) of the carrier (672). This is achieved by making the conduits protrude into the receiving section (678), as previously described. Furthermore, the width (diameter) of each conduit is sized to fit within their respective outlets and inlets. To reduce leakage of liquid or foam, flexible seal boundaries may form seals with each conduit. Additionally, or alternatively, the conduits may be sized to seal and engage with the periphery of the outlet or inlet.

[0151] The cartridge (610) and carrier (672) are configured such that when the cartridge (610) is received in the receiving section (678), the cartridge air inlet (774) is connected to the carrier air outlet (768) and the cartridge foam outlet (654) is connected to the carrier foam inlet (680). Although not shown, to reduce the risk of misconnection between the carrier air outlet (768) and the cartridge foam outlet (654), and between the cartridge air inlet (774) and the carrier foam inlet (680), the cartridge (610), the receiving section (678), or both may be shaped to allow the cartridge (610) to be received only in the correct direction. For example, the cartridge (610) may have a projection and the carrier (672) may have a recess or groove so that the cartridge (610) and carrier (672) are correctly positioned relative to each other. Alternatively, the inlet and outlet may be arranged asymmetrically so that they can be connected in only one direction.

[0152] The device may be configured to operate the stirring means only when the cartridge (610) is received in the carrier (672). To achieve this, the carrier (672) is preferably configured to detect when the cartridge (610) is received in the receiving part (678). The carrier (672) may have a switch that operates when the cartridge (610) is received in the receiving part (678). For example, the carrier (672) may have exposed electrical contacts or terminals, and the cartridge (610) may have a conductive portion placed on the cartridge (610), and the conductive portion may be configured to connect the electrical contacts when the cartridge (610) is received in the receiving part (678). Alternatively, the carrier (672) may have a manual or pressure-sensitive switch or button that is pressed down when the cartridge (610) is received in the receiving part (678). Either switch may be connected to the processor on the printed circuit board (772) so that the processor can recognize the presence of the cartridge (610) when the cartridge (610) is received by the carrier (672). In this way, the processor can operate the stirring means only when the cartridge (610) is detected and when suction is detected in the mouthpiece (764) by a pressure sensor or airflow sensor. This is to prevent the battery (760) from being drained by unintentionally operating the motor.

[0153] When the user wishes to consume foam during use, a pre-filled cartridge (610) is inserted into the receiving section (678). The carrier foam conduit 684 and the air flow conduit 766 perforate or penetrate the cartridge foam outlet (654) and the cartridge air inlet (774), respectively. The cartridge (610) operates a switch so that the processor detects the presence of the cartridge (610).

[0154] The user then inhales (sucks in) through the mouthpiece (764) of the carrier (672). This creates negative pressure in the carrier foam conduit (684), which is detected by the pressure sensor (712). The processor recognizes the presence of the cartridge (610) and activates a motor powered by the battery (760) to operate the air pump (770). The air pump (770) draws air into the cartridge (610) from the carrier air inlet (690) along the air flow conduit (766) through the carrier air outlet (768). The air is injected into the liquid through the opening (780) of the air injection conduit (776). In this way, the liquid is effectively aerated and foamed with air, and this agitation transforms the liquid into foam.

[0155] The suction applied by the user draws the foam out of the cartridge (610) through the cartridge foam outlet (654) and along the carrier foam conduit (684). This allows the user to inhale the foam into their mouth through the carrier foam outlet (682). The user may stop inhaling and stop the agitation when they have inhaled a sufficient amount of foam. Suction into the mouthpiece (764) to generate foam via agitation may be repeated to allow the user to consume more foam until the liquid in the cartridge (610) is completely consumed.

[0156] Next, refer to Figures 7 to 9. A second embodiment of the cartridge (10) for a stable foam substance inhalation device is shown. The second embodiment of the cartridge (10) for a stable foam substance inhalation device includes a flexible mixing chamber (12), an expansion chamber (14), a partition member (16), and a discharge member (18).

[0157] The flexible mixing chamber (12) has an access opening (20) at a first end (22) and is closed at a second end (24) opposite to the first end (22). The access opening (20) is sized to receive through the first and second foam-forming elements (26, 28). The access opening (20) is circular or substantially circular in shape, but may be of other shapes such as square or triangular. Similarly, the flexible mixing chamber (12) preferably has a circular cross-section, but may be of other shapes. Preferably, the second end (24) is curved so as to be considered hemispherical. However, this is not mandatory, and the second end (24) may be planar.

[0158] The flexible mixing chamber (12) has a first receiving portion (30) for slidably receiving a first foam-generating element (26) and a second receiving portion (32) for slidably receiving a second foam-generating element (28). The first receiving portion (30) is distal to the access opening (20) compared to the second receiving portion (32), and in this example is located at or adjacent to the second end (24). The second receiving portion (32) is located at or adjacent to the access opening (20). Preferably, the flexible mixing chamber (12) is sized such that the sum of the lengths of the first receiving portion (30) and the second receiving portion (32) constitutes most of the length of the flexible mixing chamber (12), and more preferably, is substantially equal to the total length of the flexible mixing chamber (12).

[0159] Preferably, the flexible mixing chamber (12) is made of a thermoplastic elastomer that provides the desired flexibility. However, other flexible materials such as silicone or other elastomer materials, for example, rubber, or other flexible plastics may be used. The flexibility of the flexible mixing chamber (12) allows for manual operation or activation by compression of the first foam-forming element, the second foam-forming element, or both. However, if other operation or activation methods are employed, the flexible mixing chamber (12) does not necessarily have to be flexible. The flexible mixing chamber (12) may preferably be transparent or translucent.

[0160] The expansion chamber (14) is preferably cylindrical or substantially cylindrical and can be considered a tube, but may have other shapes. For example, the expansion tube may have a flattened circular cross-section, i.e., an elliptical cross-section. It may also have any other shape, such as a rectangle or a triangle. This can also be applied to the flexible mixing chamber (12), the partition member (16), and the discharge member (18). The expansion chamber (14) preferably has a proximal opening (34) of the mixing chamber and a proximal opening (36) of the discharge member. Here, the openings are identical, but do not necessarily have to be. The expansion chamber (14) is also formed from a flexible material such as a thermoplastic elastomer, but this is not necessarily required. The expansion chamber (14) may preferably be transparent or translucent.

[0161] The proximal opening (34) of the expansion chamber (14) is fluidically connected to the access opening (20) of the flexible mixing chamber (12) via a partition member (16). Preferably, the partition member (16) connects the expansion chamber (14) and the flexible mixing chamber (12) in a sealed manner. That is, the partition member (16) integrally connects and seals the expansion chamber (14) and the flexible mixing chamber (12) to prevent foam leakage.

[0162] To achieve a sealed connection, the partition member (16) has a mixing chamber sealing surface (38) and an expansion chamber sealing surface (40). Preferably, each sealing surface (38, 40) is annular or substantially annular. The diameters of the mixing chamber sealing surface (38) and the expansion chamber sealing surface (40) are substantially the same as or identical to the diameters of the access opening (20) and the proximal mixing chamber opening (34) of the expansion chamber (14), respectively. This is so that the sealing surfaces (38, 40) form an interference fit with the relevant opening (end portion) of the expansion chamber (14) or mixing chamber (12). This prevents or limits the leakage of components such as foam from either chamber. The sealing surfaces (38, 40) are received in contact with the inner wall within each chamber. The access opening (20) and the proximal mixing chamber opening (34) preferably have substantially the same or identical diameters, so as to allow either sealing surface to be used for either opening. However, the diameters of the access opening (20) and the opening of the expansion chamber (14) may be different.

[0163] The partition member (16) preferably includes an external stop (42), and the mixing chamber (12) and the expansion chamber (14) are connectable to the partition member (16) on either side of the external stop (42). The stop (42) here is a ridge-like portion that extends annularly around the partition member (16) and separates the two sealing surfaces (38, 42) from each other.

[0164] Refer to Figure 10 here. The partition member (16) further includes at least one hole (44) (through hole) for fluidly connecting the expansion chamber (14) and the access opening (20). Preferably, there are two separate holes (44), which are separated by at least one (two in this example) mixing member (46). The mixing member (46) may be thought of as an arm. Furthermore, the mixing member (46) may prevent or restrict the movement of the initial state foam-generating element from the flexible mixing chamber (12) to the expansion chamber (14). Preferably, the holes (44) are curved, and the openings of the holes (44) may be elongated in shape so as to be considered slots.

[0165] The partition member (16) may further include projections (48) extending axially within the flexible mixing chamber (12). Although one projection (48) is shown in the figure, there may be multiple projections (48). Furthermore, although the projections (48) are shown in the figure as being centered on the partition member (16), they may be off-center. The projections (48) are preferably tapered or pointed in shape. In some embodiments, the side walls of the mixing chamber may also include projections.

[0166] Refer again to Figures 7 and 8. The passage (50) through the partition member (16) is at least partially composed of holes (44) and widens from the mixing chamber sealing surface (38) toward the expansion chamber sealing surface (40). The widening of this passage (50) is at a steep angle and is preferably formed, for example, by a step (52).

[0167] The discharge member (18) is located at or adjacent to one end of the expansion chamber (14) and has a discharge port (54) for discharging or releasing foam. Here, the discharge member (18) closes the proximal opening (36) of the discharge member at the end of the expansion chamber (14). The discharge member (18) includes a sealing surface (56) that connects to and seals the expansion chamber (14) in the same or similar manner as the sealing surface of the partition member (16). That is, the sealing surface (56) of the discharge member (18) is annular or substantially annular and has the same or the same diameter as the proximal opening of the expansion chamber (14) into which it is received. The discharge member (18) further includes a stopper member (58) to prevent it from being inserted too far into the expansion chamber (14).

[0168] The inner surface (60) of the discharge member (18) is concave or substantially concave to assist in directing the direction of the foam. The outer surface (62) of the discharge member (18) is convex.

[0169] Preferably, the discharge port (54) protrudes from or is spaced apart from the outer surface of the main body of the discharge member (18). The discharge port (54) is off-center from the rest of the discharge member (18) and is located on or adjacent to the lower part of the discharge member (18) when in use.

[0170] The discharge member (18) further includes a discharge conduit (64) and an inlet opening (66), the discharge conduit (64) being interconnected such that the inlet opening (66) and the outlet (54) are in fluid communication. The discharge conduit (64) has a longitudinal extension that positions the inlet opening (66) closer to the partition member (16) than the outlet (54). Furthermore, the inlet opening (66) may be located off-center relative to the rest of the discharge member (18) or the expansion chamber (14). When in use, the inlet opening (66) is preferably located on or adjacent to the lower inner surface of the expansion chamber (14).

[0171] The flexible mixing chamber (12) includes first and second foam-generating elements (26, 28). These are positioned inside the mixing chamber (12) in corresponding receiving sections (30, 32). With the foam-generating elements (26, 28) received therein, a partition member (16) is connected to the mixing chamber (12), an expansion chamber (14) is connected to the partition member (16), and a discharge member (18) is connected to the expansion chamber (14). These components may be fixed together to prevent disassembly or separation. Furthermore, two or more components may be integrally formed.

[0172] When the substances constituting the first and second foam-generating elements (26, 28) react or interact, stable foam is generated. This is preferably achieved by the foaming of a foam that is stabilized, thickened, or both.

[0173] For example, the first foam-forming element (26) consists of a carbonate (e.g., sodium bicarbonate) and an acid (e.g., citric acid). Sodium bicarbonate and citric acid are preferred, but any other carbonate (e.g., calcium carbonate) or acid (e.g., tartaric acid) having any edibility or food safety may be used. The carbonate and acid are here in solid form, for example, powdered and compressed into the first foam-forming element. It will be understood that the first foam-forming element is therefore uncompressible and may simply be a powder, but may also be a tablet or granule. In the solid state, the carbonate and acid do not react. The first foam-forming element (26) further comprises a stabilizer, a thickener, or both. Stabilizers and thickeners such as lecithin and xanthan gum are used, but any other thickener or stabilizer may be used.

[0174] The cross-sections of the first and second foam-generating elements (26, 28) are preferably circular, corresponding to the cross-section of the flexible mixing chamber.

[0175] As shown in Figure 11, the second foam-generating element (28) preferably includes a liquid container (68). In this example, the second container (68) is a water container (68), but it may contain other liquids. The water may contain a coloring agent to aid in visual identification. The container (68) is hollow, sealed, and preferably has curved ends (for example, in this example the longitudinal cross-section of the container (68) has a stadium shape). However, it may have other shapes, such as a ball shape. Alternatively, the liquid and the first foam-generating element (26) may be separated by a planar seal without using such a container (68).

[0176] The container (68) is preferably flexible and may be formed from a thermoplastic elastomer, as with the other components, but other flexible materials may be used. In an example of a flexible container, the container (68) preferably includes a hole (70) therein, which allows liquid to be discharged from there when the container (68) is squeezed. The hole (70) is preferably small so that the surface tension of the liquid maintains the liquid inside the container (68) when no pressure is applied. For example, the diameter of the hole (70) may be between 0 and 1 millimeter, and more preferably substantially 0.5 millimeters (e.g., 0.45 millimeters). A flexible container (68) having a hole (70) may be called a squeeze ball. The hole (70) is ideally located at the end of the container and oriented to face the first foam-generating element (26).

[0177] However, the container (68) may not be flexible but be rigid. In the case of a rigid (non-flexible) container (68), at least a portion of the container (68) may preferably be fragile, burstable or shatterable by manual pressure applied thereto. The rupture of at least a portion of the container (68) may release the fluid therefrom. If the container (68) is rigid, holes (70) may be present, although they are not essential.

[0178] The liquid is preferably water or consists almost entirely of water, but may instead be an acidic solution or a carbonate solution, in which case the first foam-forming element (26) may lack the acid or carbonate.

[0179] The first foam-generating element (26), the second foam-generating element (28), or both may contain additional ingredients that the user may wish to consume or inhale. The first foam-generating element (26), the second foam-generating element (28), or both may contain fragrances to enhance the user experience. Further additional ingredients are described below.

[0180] For example, the first foam-forming element (26), the second foam-forming element (28), or both may include pharmaceuticals, medicines, or dietary supplements. This may include vitamins, supplements such as pre-exercise compositions, branched-chain amino acids, creatine, other supplements commonly taken during workouts for endurance enhancement, over-the-counter medications such as cough suppressants or pain relievers, and erectile dysfunction medications such as sildenafil. Compounds taken in small amounts as needed are particularly suitable.

[0181] The first foam-generating element (26), the second foam-generating element (28), or both may contain food or beverage substances or compounds thereof. This may include, for example, flavorings or ingredients of soft drinks such as electrolyte-type sports drinks or iced tea, both of which may conventionally exist in powder form. It may also be an alcoholic beverage, in which case alcohol may be used as the liquid in the container (68). Flavorings or ingredients of confectionery or desserts may also be considered, so that the user can experience confectionery or dessert without consuming the number of calories typically associated with it. The first foam-generating element (26), the second foam-generating element (28), or both may contain caffeine, for example, the total caffeine content of the first foam-generating element (26), the second foam-generating element (28), or both may be substantially equivalent to that of a conventional espresso shot.

[0182] The first foam-forming element (26), the second foam-forming element (28), or both may contain nicotine and provide an alternative to smoking. The first foam-forming element (26), the second foam-forming element (28), or both may contain tobacco or other components of tobacco itself.

[0183] The first foam-forming element (26), the second foam-forming element (28), or both may contain cannabis or cannabis components, such as tetrahydrocannabinol (THC) and / or cannabidiol (CBD), to provide psychoactive or medicinal effects as desired. It should be noted that while cannabis is described herein, references to cannabis and its components may be omitted from this specification as necessary, given the differing legal and moral status of cannabis worldwide.

[0184] As shown in Figures 12 and 13, the cartridge (10) is received in a carrier (72) (holder) of the second embodiment for forming a second embodiment of the inhalation device (74). The carrier (72) of the second embodiment consists of a carrier body (76), a cartridge receiving portion (78) for receiving the cartridge (10) within the carrier body (76), a carrier foam inlet (80), a carrier outlet (82), and a passage (84) (conduit) between the carrier foam inlet (80) and the carrier outlet (82) that passes through the carrier body (76).

[0185] The cartridge receiving portion (78) is, in this case, a hole (recess) within the carrier body (76) and is sized to hold the cartridge (10). The rear portion (86) of the carrier body (76) is detachably attached to the rest of the carrier body (76) to allow insertion of the cartridge (10).

[0186] The outlet (54) of the cartridge (10) is in fluid communication with the carrier foam inlet (80) of the carrier (72) and may be insertable therein. The carrier foam inlet (80) includes a seal (88) for sealing the outlet (54) of the cartridge (10). The seal (88) is preferably an O-ring and may be made of elastomer.

[0187] A carrier air inlet (90) is provided at or adjacent to the carrier foam inlet (80). The air inlet (90) allows for the addition of air to the foam or the entrainment of air into the foam. Preferably, the air inlet (90) is a channel or conduit that passes through the carrier body (76) to the outside of the device. Alternatively, the air inlet (90) may be able to conduct to the outside through a void within the carrier body (76).

[0188] The Venturi tube (92) is preferably fluidically conductive to the carrier bubble inlet (80) and also preferably fluidically conductive to the carrier air inlet (90). The Venturi tube (92) has a rear opening that is fluidically conductive to both inlets (80, 92). The passage through the Venturi tube (92) may be tapered to increase the velocity of the fluid flow, but this is not required. The head portion of the Venturi tube (92) has a tapered, preferably tufted conical shape. The Venturi tube (92) may help to mix the bubbles and air.

[0189] The carrier (72) further includes a check valve (96) between a carrier bubble inlet (80) and a carrier outlet (82). The check valve (96) is positioned to prevent the user from exhaling into the cartridge (10) or device and disturbing the distribution of bubbles therein. The check valve (96) is preferably a duckbill valve. The duckbill valve is made of a flexible material and has a conical or substantially conical shape and has an opening (98) at its base. The check valve (96) includes a cut (100) along or in part to the body of the check valve (96) from the tip (forward part). The cut (100) allows fluid to flow from the base to the outside of the tip. This is because the parts of the body partitioned by the cut (100) separate from each other to form a forward opening in the check valve (96) when subjected to outward pressure from inside the body of the valve. When the tip portion (104) is subjected to inward pressure from outside the valve body, the portion of the body partitioned by the cut (100) remains in contact, obstructing the flow of fluid.

[0190] The tapered end of the venturi tube (92) is preferably received through the opening (98) at the base of the check valve (96).

[0191] The front portion (106) of the carrier body (76) is preferably removable from the rest of the carrier body (76) or the central portion (108) of the carrier body (76), for example, to assist with cleaning. The front portion (106) may include a check valve (96) or a venturi tube (92), although not shown. The front portion (106) or the central portion (108) of the carrier body (76) may include a magnetic element for improved ease of attachment and detachment. The carrier body (72) may also include a sealing element between the front portion (106) and the central portion (108).

[0192] Referring particularly to Figures 14 to 16, a second embodiment of the inhalation device (74) may also include a signaling means or indicator element (110) for indicating (signaling) that the user is inhaling from the inhalation device (74). The indicator element (110) may include a pressure sensor (112) (flow sensor) for detecting when negative pressure is applied. As shown in Figure 14, the conduit (114) (channel) extends from the passage (84) between the carrier bubble inlet (80) and the carrier outlet (82) to the pressure sensor (112). The pressure sensor (112) is preferably located in or within the rear portion (86) of the carrier (72). However, in some embodiments, the pressure sensor (112) may be located directly in or within the passage.

[0193] The display element (110) further includes a light-emitting element (116), such as a light-emitting diode, configured to light up when negative pressure is detected by a pressure sensor (112). The light-emitting element (116) is preferably located within the carrier body (76) and situated on or adjacent to the cartridge (10). For example, it is located in or adjacent to the central region of the cartridge receiving portion (78) of the carrier body (72). To accommodate the light-emitting element (116) in this position, the rear portion (86) may include a projection (118) that protrudes from the body portion of the rear portion (86) and supports the light-emitting element (116) and wiring or electrical tracks. The central portion (108) of the carrier (72) may include a hole for receiving the projection (118).

[0194] The light-emitting element (116) is electrically, electronically, or communicatively connected to the pressure sensor (112). The display element (110) may include a controller configured to determine when the pressure sensor (112) has measured negative pressure and to instruct the light-emitting element (116) to light up.

[0195] The display element (110) preferably includes a light-emitting element (116) and a battery, if present, configured to supply power to a controller. The battery is preferably a rechargeable battery, and the carrier (72) includes electrical terminals (120) for charging the battery.

[0196] The display element (110) is not essential to the device for supplying foam and therefore may not be included in the device according to the present invention. For the purpose of supplying foam, the device according to the second embodiment of the present invention lacks electrical components and does not require energization. Needless to say, this is in contrast to the device of the first embodiment, which requires energization to generate foam.

[0197] Referring particularly to Figure 16, the rear portion (86) preferably includes part of the cartridge receiving portion (78). The rear portion (86) may include at least one magnetic element (122) for detachably coupling with a magnetic element on the central portion (108) of the carrier body (76). This is advantageous because the rear portion (86) is detachably attached to the central portion (108).

[0198] When in use, the cartridge receiving section (78) is opened by removing the rear section (86). The cartridge (10) is positioned inside the cartridge receiving section (78), and the cartridge receiving section (78) is closed by reattaching the rear section (86). When inside the cartridge receiving section (78), the discharge port (54) of the discharge member (18) is inserted (connected) to the carrier foam inlet (80) of the carrier (72).

[0199] Next, the user may apply pressure to the flexible mixing chamber (12) above the second foam-generating element (28). This deforms the flexible mixing chamber (12) and applies pressure to the second foam-generating element (28), thereby causing the liquid to be discharged from the container (68) through the holes (44). The projection (48) of the partition member (16) may assist in the discharge of the liquid from the container (68) by restricting the container (68) from deforming toward the partition member (16). The pressure applied by the projection (48) may create additional pressure in the container (68) to facilitate the discharge of the liquid.

[0200] The liquid dissolves the components or chemicals within the first foam-generating element (26). In this way, for example, a carbonate and an acid can react to produce carbon dioxide, which is then ejected. This ejected foam is stabilized into a stable foam by a stabilizer and thickened by a thickener.

[0201] To form stable bubbles, a stabilizer for stabilizing carbon dioxide bubbles is preferred, but other methods may be used. For example, nitrogen gas may be used to produce smaller, more stable bubbles than conventional carbon dioxide bubbles. Although chemical reactions are described as foaming and bubble generation, other methods of foaming or bubble generation may be considered. For example, a pressurized gas vessel (68) may be released, or the liquid may be stirred to generate bubbles.

[0202] Once foam is generated, it may exit the mixing chamber (12) and move to the expansion chamber (14) where the expansion of the foam is contained. The mixing arms of the partition member (16) mix the foam as it passes through the partition member (16). This mixing is achieved by the mixing arms generating vortices in the foam as it passes through the openings formed by the mixing arms. This mixing helps dissolve the first foam-generating element (26), thereby preventing or limiting the absorption of powder.

[0203] Next, the user can inhale from the carrier outlet (82). The negative pressure or suction applied by the inhalation opens the check valve (96), drawing the foam out of the expansion chamber (14) along the discharge conduit (64) into the carrier foam inlet (80). The foam is mixed with the air being drawn in through the carrier air inlet (90). The foam-air mixture passes through the venturi tube (92), through the opened check valve (96), and into the user's mouth via the carrier outlet (82).

[0204] The user inhales only a portion of the foam in a single inhalation. Because the foam is stable, multiple inhalations can be performed over a longer period. For example, the foam remains stable or present for 15 to 30 minutes, allowing for multiple inhalations of the foam, such as effectively 50 inhalations.

[0205] When the user draws in air from the carrier outlet (82), this creates a negative pressure that acts on the pressure sensor (112), which in turn illuminates the light-emitting element (116). This provides an indication to the user or others that the device is in use.

[0206] Once the foam has been fully utilized, the user can remove the cartridge (10) by removing the rear section (86). A new cartridge (10) may then be inserted into the cartridge receiver (78) as needed.

[0207] Figures 17 to 20 show a third embodiment of the carrier (272) for the stable foam inhalation device. The aforementioned cartridge, for example, the cartridge of the second embodiment, can be received within the carrier (272) to form the inhalation device. Reference numerals for elements identical or similar to those in the second embodiment are the same as those in the second embodiment plus 200. The carrier (272) of the third embodiment is preferably similar to the carrier (72) of the second embodiment and has at least some similar or identical features.

[0208] The carrier body (276) of the carrier (272) in the third embodiment includes a movable member (324) located on or adjacent to the cartridge receiving portion (278) and located on or adjacent to the carrier foam inlet (280). The end of the movable member (324) may constitute part of the cartridge receiving portion (278). The movable member (324) is preferably movable to further expand the receiving portion toward the carrier outlet (282), i.e., away from the center of the cartridge receiving portion (278). This expands (extends) the cartridge receiving portion (278). The carrier body (276) may include grooves, recesses, or both for accommodating the movement of the movable member (324) toward the carrier outlet (282). However, the movable member may be located in another position on or adjacent to the receiving portion, such as adjacent to the rear end of the carrier body. In this case, the movable member is movable toward the rear end away from the center of the receiving portion.

[0209] The movable member (324) is preferably biased toward the cartridge receiving portion (278) via a biasing means. This may be achieved through the use of a spring. For example, a coil spring may be installed between the movable member (324) and the rest of the carrier body (276) so as to forcibly bias the movable member (324) toward the cartridge receiving portion (278). The carrier body (276) may include a stopper for the movable member (324) to maintain the position of the movable member (324) when a cartridge is not received in the cartridge receiving portion (278).

[0210] The movable member (324) may include an opening (326) for connection to the cartridge outlet. The opening (326) of the movable member (324) may actually constitute a carrier foam inlet (280). Alternatively, the cartridge outlet may be received below the movable member, with the carrier foam inlet positioned below the movable member.

[0211] The movable member (324) preferably includes a recess (328) that corresponds to the shape of the expansion chamber of the cartridge.

[0212] The use of the movable member (324) may result in the elimination of the removable rear member (286) as described in the second embodiment, since the capsule can be inserted without removing any part of the carrier body (276). However, the removable rear member may still be used if it is necessary to improve ease of use.

[0213] The carrier body (276) preferably includes a side wall (330) at or adjacent to the cartridge receiving portion (278). At least one, preferably both, side walls (330) have an access opening (332) therein. The access opening (332) is elongated and aligned in the longitudinal direction of the carrier body (276). The access opening (332) extends toward the movable portion (324). This may allow the cartridge to be moved toward the movable portion (324) by a user's finger when the cartridge is received in the cartridge receiving portion (278), thereby releasing the cartridge.

[0214] The access opening (332) is tapered, so that the larger portion of the opening is located near the rear member (286) or part of the carrier body (276). The proximity of the larger portion of the access opening (332) to the rear portion (286) allows for easy application of manual pressure to the foam-generating element to activate it and allows for the application of a large lever force from below to assist in the removal of the cartridge.

[0215] The carrier body (276) may form a gap (334) that opens to the access opening (332) below the cartridge when the cartridge receiving portion (278) receives the cartridge. Such a gap (334) is easily understood by looking at Figure 19, which shows the curved portion (336) (seat) that receives the second end of the mixing chamber. The gap (334) may be below a line extending from the seat or curved portion (336) to the carrier foam inlet (280). The gap (334) may assist in the removal of the cartridge, for example, by allowing a lever to be placed under the cartridge. The carrier (272) of the third embodiment may be used in the same or identical manner as the carrier (72) of the second embodiment, except for the insertion and removal of the cartridge and the position of application of manual pressure applied to the foam generating element. The movable member (324) moves toward the carrier outlet (282) in the direction of arrow A, expanding the receiving portion (278). The movable member (324) may be moved, for example, by being pushed together with the cartridge. The cartridge is then positioned within the cartridge receiving portion (278), and the movable member (324), under the influence of the biasing means, may move toward its original position, holding the cartridge in place.

[0216] The foam-generating element may be activated by manually applying pressure to the mixing chamber through the access opening (332). The foam is then generated and drawn in the same or similar manner as described above.

[0217] After use, the cartridge can be moved toward the carrier exit (282) by gripping the cartridge through the access opening (332) and moving the movable member (324) to enlarge the cartridge receiving section (278). The cartridge can then be removed from the cartridge receiving section (278) by applying leverage to the cartridge through the gap (334) as needed.

[0218] An access opening is described, but there is no upper wall (rib) defining the recess, and the opening may simply be a cut-out section.

[0219] In the third embodiment, an access opening and a movable part are described, but either or both of these features may be omitted.

[0220] Next, refer to Figures 20 to 23. A fourth embodiment of the stabilizing foam inhalation device (474) is shown. Reference numerals similar to or identical to those in the second or third embodiment are used as reference numerals, with 400 or 200 added to them, respectively.

[0221] The fourth embodiment of the stabilized foam inhalation device (474) has similar features to the stabilized foam inhalation device (74) of the second and third embodiments, and the description of the similar features of the second and third embodiments is considered relevant to the fourth embodiment as well.

[0222] A fourth embodiment of the stable foam inhalation device (474) includes a third embodiment of a carrier (472) and a cartridge (410), the cartridge (410) being receivable by the carrier (474). The carrier (410) includes a cartridge receiving portion (478) for receiving the cartridge (410), the cartridge receiving portion (478) may be considered to be a foam-generating element receiving portion of the carrier (472). The carrier (472) further includes an outlet (482) for discharging stable foam from the device (474) to be consumed or inhaled by the user.

[0223] The cartridge (410) is preferably non-electric, meaning it does not contain electrical components, in order to achieve its primary function of dispensing stable foam or stable foam generating elements. However, the cartridge (410) may include electrical components for auxiliary functions such as lighting.

[0224] As shown in Figures 21 and 22, the cartridge (410) contains foam-generating elements (426, 428) (or components). Here, there are two foam-generating elements (426, 428), i.e., components that interact to form stable foam when combined. The first foam-generating element (426) contains an acid and carbonate powder or tablet, as previously described. The second foam-generating element (428) contains a liquid such as water or another solvent, as previously described. However, it should be understood that the foam-generating elements may differ from those described above, as explained in the embodiments described above.

[0225] The foam-generating elements (426, 428) are received in separate chambers (412, 468) (containers) of the cartridge (410). A movable barrier is between them to prevent or limit the mixing or interaction of the foam-generating elements (426, 428) until desired. The powder (426) is received in the first chamber (412), and the liquid is received in the second chamber (468). The first and second chambers (412, 468) can be considered as the foam-generating element receiving sections of the cartridge (410).

[0226] The second chamber (468) includes a tube having an open end (538) and a closed end (540). At least a portion of the wall of the second chamber (468) is made of a flexible material so that pressure can be manually applied to the liquid received in the chamber (468). The first chamber (412) is preferably configured to seal or close the open end (538) of the second chamber (468). Here, it should be understood that the first chamber (412) is at least partially accommodating inside the second chamber (468), but may not be. The first chamber (412) preferably includes a stop (542) (here, a flange) having a diameter matching or larger than the diameter of the opening at the open end (538) of the second chamber (468) in order to prevent or limit the excessive insertion of the first chamber (412) into the second chamber (468). The flange (542) may provide support to the first chamber (412).

[0227] The first chamber (412) includes perforated walls (544, 546) (seals) at each end. The seals are preferably planar. At the first end, which forms an openable and closable barrier (544) between the foam-generating elements (426, 428), the first perforated wall (544) is preferably made of a metal foil, such as aluminum foil. However, other materials, sheets, or membranes may be used for the first perforated wall. The metal foil (544) can provide adequate sealing force and extend the cartridge shelf life.

[0228] At the second end of the first chamber (412), which can form a barrier between the cartridge (410) and the carrier (472), the second perforable wall (546) may be made of a flexible sheet or membrane, such as a sheet of food-grade silicone. However, other materials, sheets, foils, etc., may be used, and they do not necessarily have to be flexible. It should be understood that the seal at the second end of the first chamber may not be strictly necessary, for example, if the first foam-generating element is a tablet. Nevertheless, the second perforable wall (546) can contribute to providing the cartridge (410) with a long shelf life.

[0229] The second perforated wall (546) preferably forms only a portion of the second end of the first chamber (412), thereby allowing a more rigid material or structure to be used for the rest of the second end, thus contributing to maintaining the structural integrity of the first chamber and cartridge. However, it should be understood that in some configurations, the entire second end may be perforated. The second perforated wall (546) may be a sheet of a different material from the rest of the second end, or alternatively, the second perforated wall (546) may be merely a region of the second end with a thinner wall thickness to assist in perforation.

[0230] The second perforable wall (546) is preferably elongated (for reasons to be explained later in this specification).

[0231] Referring next to Figure 23, the cartridge receiving portion (478) is preferably located at or adjacent to the rear of the carrier (472), and may be an opening or recess of the carrier (472). The recess (478) may be sized to accommodate at least a large portion of the cartridge (410) inserted therein. The cartridge receiving portion (478) includes a wall (548) to prevent the cartridge (410) from being overinserted into the carrier (472). The cartridge (410) preferably closes the opening of the cartridge receiving portion (478) to prevent bubbles from escaping therefrom.

[0232] At least one, preferably two, protrusions (448a, 448b) (projections) are provided on or adjacent to the cartridge receiving portion (478), here projecting from the wall (548). The protrusions (448a, 448b) are configured to perforate the first perforable wall (544), the second perforable wall (546), or both of the cartridge (410) when it is received by the carrier (472).

[0233] The projections (448a, 448b) may be pointed to assist in perforating the perforable wall, but it should be understood that this is not always necessary. Each projection (448a, 448b) preferably also includes a passage that helps allow fluid to flow through the perforation made in the perforable wall (544, 546) by the projection (448a, 448b).

[0234] The two protrusions (448a, 448b) are spaced apart from each other. The first protrusion (448a) protrudes from the lower part of the wall (548), and the second protrusion (448b) protrudes from the upper part of the wall (548). The spacing between the protrusions (448a, 448b) facilitates proper mixing of the foam-generating elements (426, 428).

[0235] The first projection (448a) has a longer projection than the second projection (448b). In this way, the first projection (448a) is configured to extend along the lower part of the elongated second perforable wall (546), and through the first perforable wall (544) and through the first chamber (412). The first projection (448a) defines an open-top channel (550) to prevent the perforation of the first perforable wall (544) from being blocked by the first projection (448a).

[0236] The second projection (448b) is configured to partially extend within the first chamber (412). The second projection (448b) includes a bore (552) through which bubbles can flow or expand. The bore (552) extends through the second perforable wall (546). The diameter of the second projection (448b) is larger than the diameter of the second projection (448a), which may be beneficial in allowing bubbles to pass through it.

[0237] The carrier (472) preferably includes an expansion chamber (414) and a conduit (484) located between the cartridge receiving section (478) and the outlet (482). The expansion chamber (414) and conduit (484) may together be considered as a passage (fluid flow path) between the cartridge receiving section (478) and the outlet (482). The expansion chamber (414) preferably exists at or adjacent to the bore (552) of the second projection (448b) and the receiving section (478). The bore (552) may have an expansion (554) at or adjacent to the end of the expansion chamber (414) that may promote foaming. The expansion chamber (414) is so named because it provides a space for the foam to expand.

[0238] The expansion chamber (414) may be transparent so that bubbles can be seen during use. However, it should be understood that this may not always be necessary. The expansion chamber (414) may be flexible to allow for its manual operation, but again, it should be understood that this may not always be necessary.

[0239] The conduit (484) preferably extends from the outlet (482) into the expansion chamber (414). The conduit (484) preferably has an inlet opening (480) in the expansion chamber (414) for receiving foam. The inlet opening (480) of the conduit (484) is preferably off-center relative to the expansion chamber (414) at the bottom or lower part of the expansion chamber (414) during use. This allows for greater foam consumption in the expansion chamber (414) as the foam may sink to the bottom due to gravity. Additionally or alternatively, the inlet opening (480) is located proximal to the cartridge receiver (478) compared to the outlet (482). In this case as well, greater foam consumption in the expansion chamber (414) may be possible, for example, if the device is used in an inclined orientation such that the cartridge receiver (478) is lower than the outlet (482).

[0240] The conduit (484) may preferably include drops, steps, or turns (556), in which case the conduit (484) is not linear, but it should be understood that this is not mandatory. The conduit (484) may include a check valve, a venturi tube, or both, as described in the previous embodiments.

[0241] The outlet (482) (mouthpiece) is preferably cruciate or substantially cruciate, but it should be understood that other shapes may be considered. The outlet (482) may also be a flared portion of a conduit (484) from which foam can be expelled, either additionally or alternatively.

[0242] The carrier may include a holder (558) that receives the expansion chamber (414) and can define at least a portion of the conduit (484). The holder (558) may be formed of a material that is more rigid than the expansion chamber (414), for example. It should be understood that a fourth embodiment of the device (474) may include a sensor, a seal, lighting, an acoustic means, or a combination thereof, as previously described in the earlier embodiments.

[0243] In use, the fourth embodiment of the apparatus (474) may function in the same or identical manner as the second and third embodiments. The cartridge (410) is inserted into the cartridge receiving section (478). This action causes the first projection (448a) to first perforate the second perforated wall (546), extend through the first chamber (412), and then perforate the second perforated wall (544), opening the barrier between the foam-generating elements (426, 428). Similarly, the second projection (448b) may perforate the second perforated wall (546). The user can then apply pressure to the liquid by compressing the exposed end of the second flexible chamber (468), forcing it to flow into the first chamber (412) through the perforation and the channel (550) defined by the first projection (448a). This is shown by line A in Figure 23. In the first chamber (412), the foam-generating elements (426, 428) mix and interact to generate stable foam that flows (expands) into the expansion chamber (414) through the bore (552) of the second projection (448b), as indicated by arrow B. The expansion chamber (414) becomes filled or partially filled with stable foam. The stable foam may then be drawn into the user's mouth from the outlet (482) by the user's inhalation through the conduit (484) and inhaled (consumed). The stable foam may be consumed by multiple inhalations or prolonged inhalation.

[0244] As described above, it is possible to provide a device that generates stable foam, rather than a device intended only for short-term foaming or rapid inhalation of inhalants. This allows the user to ingest or inhale the substances contained in the foam over a long period of time through multiple puffs. This provides a smoking alternative or a tobacco substitute.

[0245] When used herein in connection with the present invention, the terms “comprises / comprising” and “having / including” are used to identify the presence of a described feature, integer, step, or component, but do not preclude the presence or addition of one or more other features, integers, steps, components, or groups thereof.

[0246] For clarity, it should be understood that certain features of the present invention described in the context of separate embodiments may be provided in combination in a single embodiment. Conversely, various features of the present invention described in the context of a single embodiment for the sake of brevity may also be provided separately or as any preferred subcombination.

[0247] The embodiments described above are provided for illustrative purposes only, and it will be apparent to those skilled in the art that various other modifications are possible without departing from the scope of the present invention as defined herein.
