Patent Description:
Drinking bottles, shaker bottles and other drink containers designed for sports and health enthusiasts require the manual introduction of powdered supplements such as protein powders, hydration salts, pre-workout powders, etc. via opening and closing of a particular powder's container lid, scooping the powder, and manually placing the desired powder amount into an open bottle. For correct mixing, bottles such as shaker bottles use a separate mechanical agitator to break down the powders and allow the supplements to dissolve entirely. Individuals that use these supplements and shaker devices need to separately carry their supplement powders (which often are stored in bulky containers, sealable bags, etc.) and drinking containers (which often include an independent shaker device or ball) to and from the gym, work, or school, to make use of their chosen regimen. Such a need to carry multiple containers can be a burden to the user and take up a large amount of space.

Moreover, supplements vary in their powder quantity per serving and in the amount of fluid (e.g., a liquid such as water) required to dissolve the supplement to provide the desired concentration of solution. As such, different volumes of fluid are required to accommodate proper blending of these supplements. Additionally, agitation devices may be needed to avoid clumping and ensure that the supplements being mixed with the fluid are fully dissolved.

Further still, supplements may need to be taken at different points in time relative to a workout. For example, a first supplement may be desirable prior to a workout, a second supplement may be most effective during a workout, and a third supplement may be most effective after a workout. Thus, due to the various ratios of fluid to supplement required and the potential of supplements needing to be taken at different points in time relative to a workout, a user may not be able to simply pre-mix multiple supplements together for use. Rather, these supplements must be maintained separate from one another.

Previous approaches for addressing the above problems additionally include supplement storage bottles that have external storage compartments for supplements. These supplement storage bottles with external storage compartments for supplements carry multiple supplement powders. For example, in such approaches, the storage containers and compartments are stacked below or above a fluid containing section of a drinking bottle in separate structures external to the fluid containing section.

However, such separate storage of the supplements requires several steps for use. For example, a user needs to remove the supplement storage container from the bottle, open a lid to the fluid containing section of the bottle, open a lid of the supplement storage container, add powder from the supplement storage container to the fluid containing section of the bottle, add a shaking device or ball to the fluid containing section of the bottle, and then close the bottle to use. These several steps result in use of the bottle being inefficient time-wise and an inefficient use of space. The external compartment solution further sacrifices liquid volume in order to accommodate the external compartments and retain a predetermined external dimension. The ability to store multiple supplements externally via external compartments to accommodate hydration, energy, and protein powders results in a large dimensioned bottle without the added equivalent gain in fluid volume. Moreover, one unexpected problem with the external compartment bottles is that the storage compartments are relatively close to the same diameter as the bottle itself. This makes the transfer of the powder from the compartment to the bottle challenging as powder supplements can spill outside of the diameter of the bottle with greater ease due to having no width variability with the fluid vessel thereby creating a loss in the powdered volume delivered and the subsequent concentration of solution.

Other previous approaches to address the above problems include supplement storage within the fluid containing section of the drinking bottle itself. For example, some previous approaches include a bottle that has a supplement storage container comprising a single chamber or container located inside a lid of the bottle to which supplements are added. In such designs, a shaker ball or other independent shaking device may serve as a locking mechanism for the supplement storage container and a fluid containing section containing a fluid such as water. When the user wants to use the supplement in such configurations, the user depresses a button that drops the shaker ball and supplement into the fluid containing section, where the fluid containing section is positioned below the supplement storage container. Further approaches may have a similar supplement storage container and shaking device configuration positioned at a bottom of the bottle instead of at a top of the bottle. For example, one powdered supplement may be stored inside a bottle and use the same supplement storage container and independent shaking device mechanism described above, except the powder container and shaker ball/lock are located at the base of the bottle rather than in the lid above.

However, only one supplement mixture may be used in the internal compartment solutions. Thus, users are only able to store one supplement at a time and those who consume multiple supplements are not able to benefit from the use of these bottle. Users further are not able to utilize a proper fluid to supplement ratio in a case where multiple supplements with different ratio requirements are users, and users are unable to use different supplements at different time points relative to a workout in such approaches. Moreover, these approaches are prone to leaking.

As discussed above, for supplement and liquid capacity, depending on the supplements used, the need for fluid capacity changes as well as the storage compartment size. Supplement and shaker bottles have a typical capacity of <NUM> (<NUM> ounces) of liquid volume or less. This may be sufficient volume to use hydration and energy supplements, but not enough fluid volume to dissolve protein powders adequately. Currently, manufacturers have a range of bottles with various fluid volumes from <NUM> (<NUM> ounces) to <NUM> (<NUM> ounces), and <NUM> (<NUM> ounces) versions and smaller. The available fluid volume is reduced in bottles designed to accommodate external storage compartments due to the desire to keep the external dimensions of the bottles intact as compared to non-storage type bottles.

For usability, previous approaches require users to manually remove a storage container and open a lid to add each supplement to a fluid container of the bottle if more than one supplement is needed or desired for a specific exercise regimen. In some examples, bottle bodies (a fluid container of a bottle) may be able to store one powder therein. However, as mentioned above, such approaches may be inefficient for a user to use from both a time and a space perspective. Furthermore, such approaches often come at the expense of reducing an amount of fluid that can be held by the container in order to maintain the external dimensions of the container compact.

As to previous approaches which include an independent agitator device such as a ball, there are several shortcomings. For example, one shortcoming is the probability of losing the part during washing, in kitchens, sinks, drawers, dishwashers, etc. Secondly, the independent agitator device such as a ball affects the volume of fluid available and changes the specific gravity of the fluid mixture which can result in supplements such as proteins not mixing well or clumping onto the independent agitator device. Adding to the issue of insufficient blending, the maj ority of shaker bottles on the market do not possess enough volume to accommodate a typical protein shake. As a result, protein shakes do not completely blend and end up with large clumps of supplement suspended in the fluid. For blending efficiency, some previous approaches do not include an agitator ball or independent shaking device and instead attach a fixed agitator apparatus to an underside of the lid, thereby eliminating the need for an independent shaking device or ball. The document <CIT> discloses a multi-chambered container.

The issues described above may be addressed by a container according to claim <NUM> and method of use thereof according to claim <NUM>. In this way, multiple supplements may be stored in a simple and compact manner which allows for efficient transportation and use. In particular, the container disclosed herein solves the above problems of enabling the storage of multiple powders and supplements into the same space as a liquid containing portion of the container. Moreover, the container described herein eliminates the need for an independent shaker device and streamlines a powdered supplement ingestion process via features which fit within a single drinking container with no independent shaker device or ball.

A shaft is included that connects the liquid chamber, first chamber, and second chamber to one another, where the liquid chamber, the first chamber, and the second chamber are independently rotatable about the shaft. Such features may help to avoid separate pieces which may be lost or forgotten by users. Moreover, via the chambers being independently rotatable about the shaft, individual access to the chambers may be easily achieved for filling the chambers with supplements, for example. In at least one example, a size and number of chambers may be varied to address the above-discussed challenges as to proper supplement to liquid ratios. Further, the issues described above may further be addressed via the method of claim <NUM>. In this way, a user may easily maintain separation between supplements stored in the first chamber and liquid stored in the liquid chamber and easily mix the supplements and the liquid together when desired.

It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description.

The following description relates to a multi-chamber container and methods. Via the multi-chamber container and methods discloses herein, convenient and efficient storage and use of liquid and liquid-mixable powder supplements from within a single bottle may be achieve, where these powder supplements may be exercise supplements. As discussed at method example <FIG>, the containers disclosed herein may include a plurality of chambers that are separated by dividers, where the dividers between the chambers may be opened and closed via rotation to mix various products loaded into the chambers. At least one of the chambers may be a liquid chamber, while remaining chambers may be for the storage of separate powdered supplements or other dry products. Thus, the dividers separating the chambers may be liquid tight. As seen in <FIG>, the dividers may be seals made of a flexible material framed with spokes, where these seals are opened and closed via rotation of external rings of the container that are coupled to the spokes. The ability to position the chambers about a shaft advantageously keeps the chambers together in a single unit while allowing positioning adjustments for purposes of loading the chambers. The locking of the container via the switch and the alignment mechanism may beneficially help to prevent leaks. In at least one example, the dividers may be rotatable disks that are rotated relative to one another to adjust an alignment of openings in the disks, as shown in <FIG>. When the openings are aligned, the disks allow communication of the chambers between which they are positioned. When the openings are offset, the disks prevent communication of the chambers between which they are positioned. The chambers may be directly coupled to one another via threaded rings, as also shown at <FIG>. In one or more examples, the dividers may include a nested cylindrical structure configuration, as shown at <FIG>. In this nested cylindrical structure configuration, a first cylindrical structure is positioned within a second cylindrical structure, and the first and second cylindrical assembly is positioned within a liquid chamber. The first cylindrical structure comprises a plurality of chambers for storing products such as powdered supplements. The second cylindrical structure comprises openings which are configured to only be able to expose one chamber of the first cylindrical structure at a time. Thus, in this nested cylindrical structure configuration, the first and second cylindrical structure may be rotated relative to one another to expose one chamber at a time to the liquid chamber within which the assembly is positioned. In one or more examples, the dividers may be opened and closed via a valve configuration, as shown at <FIG>. In such valve configurations, each chamber may have a corresponding valve and valve switch. By rotating a valve switch, the corresponding chamber may be transitioned into and out of communication with a liquid chamber positioned therebelow.

<FIG> show example configurations with relative positioning of the various components. It is noted that the example multi-chamber containers described are portable and handheld in size. If elements in <FIG> are shown directly contacting each other, or directly coupled, then such elements may be referred to as directly contacting or directly coupled, respectively, at least in one example. Similarly, elements shown contiguous or adjacent to one another may be contiguous or adjacent to each other, respectively, at least in one example. As an example, components laying in face-sharing contact with each other may be referred to as in face-sharing contact. As another example, elements positioned apart from each other with only a space there-between and no other components may be referred to as such, in at least one example. As yet another example, elements shown above/below one another, at opposite sides to one another, or to the left/right of one another may be referred to as such, relative to one another. Further, as shown in the figures, a topmost element or point of element may be referred to as a "top" of the component and a bottommost element or point of the element may be referred to as a "bottom" of the component, in at least one example. As used herein, top/bottom, upper/lower, above/below, may be relative to a vertical axis of the figures and used to describe positioning of elements of the figures relative to one another. As such, elements shown above other elements are positioned vertically above the other elements, in one example. As yet another example, shapes of the elements depicted within the figures may be referred to as having those shapes (e.g., such as being circular, straight, planar, curved, rounded, chamfered, angled, or the like). Further, elements shown intersecting one another may be referred to as intersecting elements or intersecting one another, in at least one example. Further still, an element shown within another element or shown outside of another element may be referred as such, in one example.

Common features and/or configurations may be shared in the various examples provided in <FIG>. Therefore, for purposes of discussion, <FIG> will be described collectively, with common elements being labeled similarly and not being reintroduced.

Turning to <FIG> shows a first view of a first example container <NUM> comprising multiple chambers, including a liquid chamber <NUM>, a first chamber <NUM>, a second chamber <NUM>, and a third chamber <NUM>. In at least one example, the first chamber <NUM>, the second chamber <NUM>, and the third chamber <NUM> may be used to store powdered supplements. The liquid chamber <NUM> may be used to store water or other suitable liquids.

A top surface <NUM> and an access point <NUM> of the liquid chamber <NUM> form a top surface of the first example container <NUM>. It is noted that access point <NUM> is shown with a lid positioned thereon in <FIG> and that access point <NUM> includes both the lid 112a and opening 112b illustrated in <FIG> or <FIG>, in at least one example. The opening 112b is a drinking opening for a user. The sidewall of the first example container <NUM> comprises liquid chamber sidewall <NUM>, first chamber sidewall <NUM>, second chamber sidewall <NUM>, and third chamber sidewall <NUM>, as well as locking mechanism <NUM>, first external ring <NUM>, second external ring <NUM>, and third external ring <NUM>.

Locking mechanism <NUM> of the first example container <NUM> includes shaft <NUM>, switch <NUM>, and alignment mechanism <NUM>, where the locking mechanism <NUM> extends from access point <NUM> to the first chamber <NUM>, and where the locking mechanism <NUM> is on a same side of the container as access point <NUM>. The shaft <NUM> of the locking mechanism may further extend to the second chamber <NUM>, and the third chamber <NUM>. Switch <NUM> is in an unlocked position in <FIG>, which permits rotation of shaft <NUM> to adjust a positioning of the chambers about shaft <NUM>. Shaft <NUM> of locking mechanism <NUM> extends in a direction parallel to a longitudinal axis (see shaft longitudinal axis <NUM> at <FIG>) of the first example container <NUM>. Shaft <NUM> of the first example container <NUM> is positioned within a shaft receiving opening (see shaft receiving opening <NUM> at <FIG>) included in each of the liquid chamber <NUM>, the first chamber <NUM>, the second chamber <NUM>, and the third chamber <NUM>. In this way, the shaft <NUM> couples the liquid chamber <NUM>, the first chamber <NUM>, the second chamber <NUM>, and the third chamber <NUM> to one another.

At least one of the chambers of liquid chamber <NUM>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> may be independently rotated about shaft <NUM>. In at least one example, each of the chambers may be independently rotated about shaft <NUM>. That is, each of liquid chamber <NUM>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> may be rotated about shaft <NUM> individually. In one or more examples, however, it is also possible that one or both of liquid chamber <NUM> and the third chamber <NUM> have a fixed position relative to shaft <NUM> and that only first chamber <NUM> and second chamber <NUM> are able to be pivoted independently about shaft <NUM>. Or, in at least one example, only one of the chambers may be rotated about shaft <NUM>.

Via a coupling in which at least one of the chambers is rotatable about shaft <NUM>, improved accessibility to the chambers may be achieved to improve overall efficiency in using the first example container. For example, as shown in <FIG>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> are all accessible due to a position of the first chamber <NUM> and the second chamber <NUM>. In particular, first chamber <NUM> and second chamber <NUM> have been independently rotated about shaft <NUM> so that the first chamber <NUM> and the second chamber <NUM> are positioned offset from the liquid chamber <NUM> and the third chamber <NUM>. The first chamber <NUM> and the second chamber <NUM> are further offset from one another. Such exemplary positioning as shown in <FIG> thus enables easy access to all of chambers. It is noted that a positioning of the chambers relative to one another may be adjusted as desired about the shaft <NUM>.

Looking to first chamber <NUM>, second seal <NUM> is positioned between first chamber <NUM> and second chamber <NUM> is in an open position. It is noted that a first seal similar to second seal <NUM> is positioned between first chamber <NUM> and liquid chamber <NUM> at first external ring <NUM>, though not shown in the view at <FIG>. Such a first seal may be seen at <FIG>. The features described in relation to second seal <NUM> also apply to all other seals of the container, including first seal (such as the first seal <NUM> shown in <FIG>) and third seal <NUM>.

Second seal <NUM> comprises a flexible and liquid tight material, such as rubber or silicon. In an open position, second seal <NUM> enables fluidic communication between first chamber <NUM> and second chamber <NUM>. Second seal <NUM> may be transitioned between the open position shown in <FIG>, and a closed position, where the closed position of second seal <NUM> is similar to the position of third seal <NUM> in <FIG>. Reference one of the first seal, second seal <NUM>, and third seal <NUM> being in a closed position refers to fully closed, such that a liquid seal is formed. Reference to one of the first seal, second seal <NUM>, and third seal <NUM> being in an open position refers to a position in which liquids may move past the seal. That is, in the open position, an opening such as opening <NUM> shown at a partial view of third example container <NUM> in <FIG>, formed by the seal.

Second seal <NUM> may be transitioned between an open position and a closed position via rotation of second external ring <NUM>. As the second external ring <NUM> is rotated, a plurality of spokes of the second seal <NUM> and a material of the second seal <NUM> are drawn in close to one another until in a closed position. In the closed position, a liquid tight seal is formed and the second seal <NUM> fully extends across the first example container to cover an area of the first example container <NUM> at the position of second external ring <NUM>. The inclusion of such spokes in the flexible material seals advantageously helps to provide a stronger seal and seals in a more efficient manner (with less twisting) compared to previous approaches such as by Frolin in <CIT>. Therein, flexible material seals are formed by twisting the material until a seal is formed. However, these seals do not include spokes as in the approach herein to assist in forming a tight seal or to improve an efficiency in forming the seal. Thus, the seal in Frolin would require more twisting than in the subject application and the seal ultimately formed would lack the sealing advantages which the structure from the spokes add.

As may be seen in <FIG>, second external ring <NUM> includes a geared-teeth shaping to improve an ability to grip second external ring <NUM> while rotating the second external ring <NUM>. Similarly, first external ring <NUM> and third external ring <NUM> also include geared-teeth shaping for improved gripping. Though a geared-teeth shaping is shown in <FIG>, other types of shaping to improve an ability of a user to grip the external rings is possible. For example, a dimpled texture, dotted texture, spline shaping, or vertical grooves and ridges may be included to improve gripping of the external rings. Moreover, in at least one example, each of the first external ring <NUM>, second external ring <NUM>, and third external ring <NUM> may include a lip which extends over a chamber positioned beneath the external ring to help improve sealing between the chambers. Additionally or alternatively, a gasket may be included between the external rings and the chambers to improve sealing. For example, first external ring <NUM> may be shaped with a lip and/or a gasket which fits with first chamber <NUM> in order to improve sealing between liquid chamber <NUM> and first chamber <NUM> when the first seal at first external ring <NUM> is open.

As discussed in greater detail herein, second seal <NUM> comprises a plurality of spokes. The plurality of spokes and the material of second seal <NUM> (such as rubber or silicon) may be coupled to an inner surface of second external ring <NUM>. That is, a portion of each of the spokes proximal the inner surface of second external ring <NUM> is coupled to the inner surface of second external ring <NUM>. The plurality of spokes comprises a flexible yet strong material. For example, the spokes may comprise wire or a metal ribbon, for example. The plurality of spokes may be at least slightly biased towards a closed position in which the spokes are pressed against each other. Further, the material of the second seal <NUM> may be pulled across the plurality of spokes. In this way, when in a closed position, the first seal, second seal <NUM>, and third seal <NUM> are liquid tight. Therefore, if the first seal is closed, liquid chamber <NUM> does not communicate with any of first chamber <NUM>, second chamber <NUM>, and third chamber <NUM>. The plurality of spokes may be transitioned from the closed position to an open position to open the second seal <NUM> by rotating the second external ring <NUM> to which the plurality of spokes is connected. As the second external ring <NUM> is adjusted, the ends of the spokes coupled to the inner surface of second external ring <NUM> are rotated. As the ends of the spokes are rotated, ends of the spokes not coupled to the inner surface of the second external ring <NUM> are pulled apart to form an opening.

By adjusting the first seal, second seal <NUM>, and third seal <NUM> between various combinations of open and closed positions, communication between the chambers of the container may be adjusted. Such an ability to adjust communication between the chambers of the container may be especially advantageous in cases where various supplements are of interest for a user. For example, in a case where a user may wish to use supplements a different times, a first supplement may be stored in the first chamber <NUM>, a second supplement may be stored in the second chamber <NUM>, and a third supplement may be stored in the third chamber <NUM>. For example, the first supplement may be a pre-workout supplement, a second supplement may be a supplement for during a workout, and a third supplement may be a post-workout supplement. In other examples, one or more of the first supplement, the second supplement, and the third supplement may be the same supplement, however.

In at least one example, a user may adjust a positioning of the chambers about shaft <NUM> as shown in <FIG>. Then, second seal <NUM> may be transitioned to a closed position via rotation of second external ring <NUM>, and the first supplement may be loaded into first chamber <NUM>. Once the first supplement is loaded into first chamber <NUM>, the second supplement may be loaded into second chamber <NUM>, and the third supplement may be loaded into third chamber <NUM>. The chambers may then all be positioned into alignment, such as shown at <FIG>. As the first seal, second seal <NUM>, and third seal <NUM> are all closed, the supplements may be maintained separate from one another. A liquid, such as water, may be loaded into liquid chamber <NUM> via the opening of access point <NUM>. When it is desired to mix the first supplement, first external ring <NUM> may be rotated to transition the first seal from a closed position into an open position. By opening the first seal between the liquid chamber <NUM> and the first chamber <NUM>, the first supplement (such as a pre-workout) supplement may mix with the liquid loaded into the liquid chamber <NUM>.

After consumption of the first supplement and liquid mixture, additional liquid may be added to the liquid chamber <NUM> and to the first chamber <NUM> via the opening of access point <NUM> (after removing the lid positioned thereon), as the first seal is still in an open position. Then, second external ring <NUM> may be rotated to transition the second seal <NUM> from the closed position to an open position. For example, to transition the second seal <NUM> from the closed position to the open position, the second external ring <NUM> may be rotated in a same direction as the first external ring <NUM> was rotated to transition the first seal from the closed position into an open position. By opening the second seal <NUM>, the second supplement (such as a supplement for during a workout) in the second chamber <NUM> may be mixed with the liquid stored in the space defined by liquid chamber <NUM> and the first chamber <NUM>.

After consumption of the second supplement and liquid mixture, additional liquid may be added to the liquid chamber <NUM>, the first chamber <NUM>, and the second chamber <NUM> via the opening <NUM> of access point (after removing the lid positioned thereon), as the first seal and the second seal <NUM> are in an open position. Then, third external ring <NUM> may be rotated to transition the third seal <NUM> from the closed position to an open position. By opening the third seal <NUM>, the third supplement (such as a supplement for after a workout) in the third chamber <NUM> may be mixed with the liquid in the space defined by the liquid chamber <NUM>, first chamber <NUM>, and second chamber <NUM>. In at least one example, as illustrated in <FIG>, third chamber <NUM> may hold a larger volume than the first chamber <NUM> and the second chamber <NUM>. This is because post workout supplements such as protein shakes are often a greater value than other supplements. Moreover, post workout supplements (particularly protein shakes) require more liquid volume than typical supplements used before and during workouts. Thus, the positioning as shown in <FIG> of third chamber <NUM> to be positioned below liquid chamber <NUM>, first chamber <NUM>, and second chamber <NUM>, is further advantageous as to ensuring increased capacity for liquid to ensure proper mixing.

Turning now to <FIG> shows a view of a second example container <NUM> in an aligned position. In one or more examples, second example container <NUM> may be first example container <NUM> in a second position. For example, the chambers of second example container <NUM> may be rotated about shaft <NUM> to transition from first example container <NUM> to second example container <NUM>. Switch <NUM> is in a locked position in <FIG>, thus preventing shaft <NUM> from rotating in the second example container <NUM> shown in <FIG>. As such, a positioning of the chambers of the second example container <NUM> (liquid chamber <NUM>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM>) are unable to be rotated about the shaft <NUM>. In order to permit such rotation of the chambers about shaft <NUM>, switch <NUM> must first be transitioned from the locked position shown in <FIG> to the unlocked position shown in <FIG>. That is, the switch <NUM> must be transitioned from a downward extending position which locks shaft <NUM> to an upward extending position which unlocks shaft <NUM>.

As may be seen in <FIG>, a shaft longitudinal axis <NUM> of shaft <NUM> extends in a direction parallel to a container longitudinal axis <NUM> of second example container <NUM>. Moreover, a housing <NUM> of the shaft is shown, where each of the liquid chamber <NUM>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> include a housing <NUM> for shaft <NUM> that includes an opening therein such as shaft receiving opening <NUM> shown in <FIG>. The housing <NUM> is a projection which surrounds a circumference of the shaft <NUM> for a height of the respective chamber. In between chambers, when overlapping with the first external ring <NUM>, second external ring <NUM>, and third external ring <NUM>, shaft <NUM> is exposed and not retained in a housing. The shaft <NUM> is thus protected in housing <NUM> at regions where shaft <NUM> overlaps with the chambers and is exposed at regions <NUM> where shaft overlaps with the external rings. In this way, the shaft <NUM> may be protected from degradation while still allowing for independent movement of the chambers.

Turning now to <FIG>, a fourth example container <NUM> is shown. It is noted that the fourth example container <NUM> may be a partial view of one of the containers shown in <FIG>. As seen at <FIG>, switch <NUM> is housed in a switch housing <NUM>. The switch housing <NUM> includes a groove in which the switch <NUM> is held. The groove of switch housing <NUM> streamlines the switch when in a locked position, such as at <FIG>. That is, the groove of switch housing <NUM> helps to keep switch <NUM> in a position such that switch <NUM> is not easily caught on objects incidentally.

Turning to <FIG>, a fifth example container <NUM> is shown. It is noted that fifth example container <NUM> may be an alternative view of one of the containers shown in <FIG> in at least one example. As is seen in <FIG>, a mixing element <NUM> comprising a spoke <NUM> and hub <NUM> configuration is fitted within liquid chamber <NUM>, adjacent first seal <NUM>. In particular, mixing element <NUM> is positioned immediately above first seal <NUM>. Via such positioning, where the first seal <NUM> is positioned between the mixing element <NUM> and first chamber <NUM>, mixing of supplements from any of the first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> with liquid from the liquid chamber <NUM> is passed through the mixing element <NUM> prior to being flowed through the opening of access point <NUM> formed in the top of liquid chamber <NUM> for drinking. In this way, technical advantages as to improved mixing are achieved. Further, the drawbacks of independent mixing devices, such as the need for a user to remember to bring such devices, are at least partially addressed.

The hub <NUM> of the mixing element <NUM> comprises an opening extending along a container longitudinal axis through the mixing element <NUM>. The spokes <NUM> of mixing element <NUM> extend from the hub <NUM> of mixing element <NUM> to an inner surface of sidewall <NUM> of the liquid chamber <NUM>. The openings formed between adjacent spokes <NUM> enable liquid that may be stored in liquid chamber <NUM> and supplements that may be stored in the chambers to mix. The inclusion of spokes <NUM> advantageously prevents clumping of supplements when mixing with liquid in the fifth example container <NUM>. Each of the spokes <NUM> may be shaped as parallel curved pieces, wherein adjacent spokes of the spokes <NUM> are spaced apart to form a plurality of openings between the spokes <NUM>. However, alternative shaping of the spokes <NUM> is possible. For example, each of the spokes <NUM> may be shaped as straight rods or a zigzag shape among other possibilities that extend from the hub <NUM> to the inner surface of sidewall <NUM>. Further, additionally or alternatively, materials such as a mesh material may be included in mixing element <NUM>. For example, a mesh or mesh-like material may extend in the openings formed between adjacent spokes, or in at least one example a mesh or mesh-like material may be used as an alternative to the spoke <NUM> and hub <NUM> configuration.

Turning now to <FIG> shows a view of a sixth example container <NUM>. In at least one example, sixth example container <NUM> may be an alternative view of one of the containers shown in <FIG>.

Sixth example container <NUM> shows a close-up view of the alignment mechanism <NUM> included between each chamber and an adjacent external ring. In particular, an alignment mechanism <NUM> is included between liquid chamber <NUM> and first external ring <NUM>, between first chamber <NUM> and second external ring <NUM>, and between second chamber <NUM> and third external ring <NUM>.

Each alignment mechanism <NUM> comprises an alignment projection 134a and an alignment notch 134b, where alignment projection 134a fits into alignment notch 134b. Alignment projection 134a may be a substantially rectangular projection, in at least one example. In at least one example, alignment projection 134a may include a gripping surface, so that alignment projection 134a may be easily gripped and slid vertically up and down in a direction parallel to a container longitudinal axis. Alignment notch 134b may be a groove recessed relative to an external surface sidewall of a chamber. For example, looking to liquid chamber <NUM> at <FIG>, alignment notch 134b is recessed relative to an external surface of the sidewall of liquid chamber <NUM>. A shaping of the alignment projection 134a may substantially correspond to a shaping of alignment notch 134b in order to allow a friction fit to hold the alignment projection 134a within alignment notch 134b, in at least one example. Additionally or alternatively, a latching mechanism may also be included to hold the alignment projection 134a within alignment notch 134b.

An unlocked position of alignment mechanism <NUM> may be a position in which alignment projection 134a is fit completely within alignment notch 134b. In particular, alignment projection 134a and alignment notch 134b may be specifically sized so that when a top of alignment projection 134a is positioned against a top of alignment notch 134b, a bottom of alignment projection 134a does not overlap with any external ring of the container. That is, the alignment projection 134a only overlaps a chamber of corresponding alignment notch 134b when the alignment mechanism <NUM> is in a locked position. Put another way, alignment notch 134b has a first extreme end and a second extreme end, where the first extreme end is closer to the mouth of the water bottle than the second extreme end. When the alignment projection 134a touches the first extreme end of the alignment notch 134b in a first position, the alignment mechanism is unlocked and a corresponding ring may be rotated. When the alignment projection 134a touches the second extreme end of alignment notch 134b in a second position, the corresponding ring is prevented from rotating. When the alignment projection 134a is not in contact with the first or second extreme ends of alignment notch 134b in a third position, then ring is still block from rotating.

For example, liquid chamber <NUM> in <FIG> shows an example where alignment mechanism <NUM> is in an unlocked position. As may be seen in <FIG> at liquid chamber <NUM>, in an unlocked state of alignment mechanism <NUM>, alignment projection 134a is fit into alignment notch 134b. In this unlocked position of alignment mechanism <NUM>, the alignment projection 134a is fully above first external ring <NUM> and does not overlap first external ring <NUM>. The alignment projection 134a is held within alignment notch 134b via a friction coupling between the alignment projection 134a and the alignment notch 134b, in at least one example.

Looking to first chamber <NUM> at <FIG>, alignment mechanism <NUM> is in a locked position. It is noted that the alignment mechanisms <NUM> are in a locked position when the alignment projection 134a overlaps with an alignment notch 134b and overlaps with a corresponding external ring. As may be seen at the alignment mechanism <NUM> of first chamber <NUM>, the alignment projection 134a is partially positioned in a groove formed in second external ring <NUM> and partially positioned in alignment notch 134b. In at least one example, alignment projection 134a may have been transitioned from an unlocked position (such as shown at liquid chamber <NUM>) to the locked position via sliding of the alignment projection 134a towards the second external ring <NUM> in a downward direction.

Via such positioning of the alignment projection 134a at first chamber <NUM>, rotation of second external ring <NUM> is prevented.

Looking to second chamber <NUM> at <FIG>, alignment mechanism <NUM> is in a fully locked state, where a bottom of alignment projection 134a is substantially aligned with a bottom of third external ring <NUM>. That is, in the fully locked state, the alignment mechanisms <NUM> are partially positioned in alignment notch 134b while the bottom of the alignment projection 134a is substantially aligned with the bottom of a corresponding ring. In the fully locked state of one of the alignment mechanisms, the corresponding external ring is prevented from being rotated. Further, the corresponding chamber is prevented from being rotated about shaft <NUM>. Thus, in the fully locked position of the alignment mechanism <NUM> as shown at third chamber <NUM> in <FIG>, rotation of the third external ring <NUM> is prevented and rotation of second chamber <NUM> about shaft <NUM> is prevented. The fully locked state may be a stronger locked state than the locked state shown at first chamber <NUM> of <FIG>, in at least one example. Nonetheless, rotation of corresponding external rings and chambers may be prevented whether in a locked state as shown at first chamber <NUM> or the fully locked state as shown at second chamber <NUM>.

In at least one example, the alignment mechanisms <NUM> may be positioned such that the alignment mechanisms <NUM> may only be in a locked position (including a fully locked position) when a corresponding chamber is in an aligned position. It is noted that such an aligned positioning refers to positioning such as shown at <FIG>, where an overall aligned chamber formation is created. In at least one example, aligned positioning of each of the chambers results in a liquid tight seal being formed between all of the chambers. Thus, in such cases, by only allowing locking of the alignment mechanisms <NUM> when the chambers are in an aligned position, the technical effect of preventing leakage is achieved. Moreover, by preventing rotation of the external rings when the alignment mechanisms <NUM> are in the locked position, an unwanted repositioning of seals may be achieved.

Turning now to <FIG> shows a seventh example container <NUM>. In at least one example, sixth example container <NUM> may be an alternative view of one of the containers shown in <FIG>. As may be seen in <FIG>, a gasket <NUM> is positioned along a rim of a top edge of third chamber <NUM>. Though gasket <NUM> is only illustrated along the rim of the top edge of third chamber <NUM>, it is noted that similar gaskets may be included at remaining chambers, including liquid chamber <NUM>, first chamber <NUM>, and second chamber <NUM>. For example, a top rim of one or both of the first chamber <NUM> and the second chamber <NUM> may include a gasket positioned therein, similar to third chamber <NUM>. Additionally or alternatively, each of the external rings may include a gasket positioned along an inner rim. Such inclusion of one or more gaskets in these particular positions may achieve the technical effect of preventing leakage.

Turning now to <FIG> shows views of an eighth example container in a first position <NUM> and the eighth example container in a second position <NUM>. It is noted that the eighth example container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example.

Looking to the eighth example container in the first position <NUM>, the first position includes switch <NUM> in an unlocked position. In the unlocked position, the shaft <NUM> may rotate freely. Thus, chambers of the container may be more easily rotated. As seen in <FIG>, switch <NUM> extends in a direction substantially parallel to a container longitudinal axis (see <FIG>) in the unlocked position. Due to the switch <NUM> being positioned in the unlocked position, the switch <NUM> extends outside of housing <NUM>. In particular, the switch <NUM> extends above housing <NUM>. The switch <NUM> extending above housing <NUM> achieves the technical effect of providing a clear indication when the switch <NUM> is in the unlocked position. That is, the switch <NUM> positioning in the unlocked state is such that a user's attention may be drawn to the switch <NUM>. This is advantageous, as the user may be alerted that potentially unwanted rotation of the chambers is possible.

Looking to the eighth example container in the second position <NUM>, the second position includes switch <NUM> in a locked position. In the locked position, chambers of the container may be prevented from easily rotating, as the shaft <NUM> is prevented from rotating. The ability to prevent rotation of the shaft <NUM> is particularly advantageous in combination with the alignment mechanism described in detail at <FIG>, as two sets of locks may be included to prevent unwanted rotation of the chambers. It is noted that the switch <NUM> is received in a groove of housing <NUM> when in the locked position in such a manner that the switch <NUM> is not easily seen. That is, the configuration of the switch <NUM> in the locked position is not configured to draw a user's attention as to the locked position. Positioning of the switch <NUM> to fit within the groove of housing <NUM> provides an indication that enables a switch <NUM> to be quickly evaluated as in the locked position.

Turning now to <FIG> shows a ninth example container <NUM>. It is noted that the ninth example container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. In the ninth example container <NUM>, the access point <NUM> (such as at <FIG>) is shown with lid 112a removed from the opening 112b of access point <NUM>. The lid 112a may be coupled to a structure defining opening <NUM> via threading <NUM>. Additionally or alternatively, the lid 112a may be coupled to the opening 112b via a friction fit. In the ninth example container <NUM>, the opening 112b is a drinking opening, where a spout structure <NUM> defines a portion of the opening 112b. Additionally or alternatively, however, an entire top surface <NUM> may comprise a lid that is removable to provide access to liquid chamber <NUM>. Or, in at least one example, a straw structure may be utilized rather than a spout structure to define a passage for accessing contents within the liquid chamber <NUM>.

The opening 112b extends through spout structure <NUM> and through a top surface <NUM> into the liquid chamber <NUM>. Thus, contents positioned within liquid chamber <NUM> are accessible via opening 112b.

Turning to <FIG> shows a tenth example drinking container <NUM>. It is noted that the tenth example container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. The tenth example container <NUM> at <FIG> is in an aligned chamber formation.

Turning to <FIG> shows an eleventh example drinking container <NUM>. It is noted that the eleventh example container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. Spokes <NUM> of first seal <NUM> are shown in <FIG>. It is noted that first seal <NUM> is in a closed position at <FIG>. As such, in the first seal <NUM> is shown creating a liquid tight barrier in <FIG>.

Looking to <FIG> shows a twelfth example drinking container <NUM>. It is noted that the twelfth example container <NUM> at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. Mixing element <NUM> is illustrated above first seal <NUM>, where first seal <NUM> is in an open position.

Turning now to <FIG> shows an example cross-sectional view of a thirteenth example container <NUM>. It is noted that the thirteenth example container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. In particular, the cross-section view at <FIG> is of housing <NUM> and switch <NUM>.

As seen in <FIG>, switch <NUM> is in an unlocked position, such that teeth <NUM> at a head <NUM> of switch <NUM> are disengaged from teeth receiving grooves <NUM> formed into shaft <NUM>. A tail <NUM> of switch <NUM> is extended in such a manner that it is clearly visible beyond the housing. The tail <NUM> being clearly visible beyond the housing advantageously acts as a clear indicator to the user that the switch <NUM>, and thus shaft <NUM>, is in an unlocked state. Thus, shaft <NUM> may be free to rotate at <FIG>. It is noted that a sloped surface <NUM> of the housing allows for switch <NUM> to be hidden when it is in a locked position. Recess <NUM> formed directly below sloped surface <NUM> enables a user to more easily move switch <NUM> from a fully locked to position towards an unlocked position. In particular, recess <NUM> provides improved accessibility to tail <NUM> when switch is in the locked position, so that a user may move the switch <NUM> via tail <NUM>.

Looking to <FIG> shows an example cross-sectional view of a fourteenth container <NUM>. It is noted that the fourteenth container at <FIG> may be an alternative view of one of the containers shown in <FIG> in at least one example. In particular, fourteenth container <NUM> is the same container as shown in <FIG> but in a different position.

As seen in <FIG>, switch <NUM> is in locked position, where the locked position is a position in which at least one of teeth <NUM> is engaged with a corresponding one of the teeth receiving grooves <NUM>. In particular, compared to <FIG>, switch <NUM> has been rotated about a center of head <NUM> by tail <NUM> being moved in a downward direction so that one of the teeth <NUM> has engaged one of the teeth receiving grooves <NUM>. Via the engagement between one of the teeth <NUM> and one of the teeth receiving grooves <NUM> as shown in <FIG>, rotation of shaft <NUM> may be prevented. However, while <FIG> is considered to show a locked position, the position of switch <NUM> is not a fully locked position. Thus, tail <NUM> is positioned outside of housing to still provide an indication at <FIG>.

A fully locked position of switch <NUM> is a position in which tail <NUM> is positioned against sloped surface <NUM> and multiple sets of teeth <NUM> are engaged with the corresponding multiple teeth receiving grooves <NUM>. In the fully locked position, switch <NUM> is fully received in the housing for the switch <NUM>, and the switch <NUM> is not easily visible. In such a fully locked position of switch <NUM>, the locking position may be more secure and rotation of shaft <NUM> may be better prevented than in a position where the switch <NUM> (and thus shaft <NUM>) is not fully locked.

Via the tail <NUM> being visible unless switch <NUM> in the fully locked state, advantages as to a user being able to quickly evaluate a state of the shaft <NUM> are achieved. For example, a user may be able to quickly evaluate whether the shaft <NUM> is unlocked or locked by looking at switch <NUM>, as tail <NUM> of switch <NUM> is visible beyond the housing unless the switch <NUM> is in fully locked position.

Turning to <FIG>, a fifteenth example container <NUM>, sixteenth example container <NUM>, seventeenth example container <NUM>, eighteenth example container <NUM>, and nineteenth example container <NUM> are shown. It is noted that the containers at <FIG> may be the same container in different positions. In the examples at <FIG>, substantially similar features as in the previous example containers are included. However, no lid is shown at access point <NUM>, though a lid may be included in at least one example. Further, a shaft system and alignment mechanisms are not included. Rather, the chambers are coupled to one another via a coupling ring <NUM> which includes threaded coupling elements. For example, liquid chamber <NUM> and first chamber <NUM> may be coupled via coupling ring <NUM>. Similar coupling rings may be included between first chamber <NUM> and second chamber <NUM>, and between second chamber <NUM> and third chamber <NUM>. Each of first seal <NUM>, second seal <NUM>, and third seal <NUM> are shown in a closed position at <FIG>. At <FIG>, the first seal <NUM> is shown in a partially open position, while remaining second seal <NUM> and third seal <NUM> are shown still in a closed position. At <FIG>, the first seal <NUM> is completely open, while the second seal <NUM> and third seal <NUM> are shown still in the closed position. At <FIG>, the first seal <NUM> is still in the fully open position, the second seal <NUM> is partially open, and the third seal <NUM> is shown in a fully closed position. Though not illustrated, in at least one example, third seal <NUM> may also be transitioned to an at least partially open position. <FIG> shows a nineteenth example container <NUM> in a fully assembled state. That is, all of the chambers are coupled to one another in <FIG>.

Turning to <FIG>, an example side views <NUM>, <NUM>, and <NUM> are shown of a twentieth example container, and a twenty-first example container <NUM> are shown. It is noted that <FIG> may be alternative views of one of the containers shown in <FIG> in at least one example.

As illustrated, it can be seen in <FIG> that spokes <NUM> are engaged with an inner surface of external rings. For example, spokes <NUM> at first seal <NUM> are shown engaged with the inner surface of first external ring <NUM>. A material <NUM> of first seal <NUM> is coupled to the spokes <NUM>. Thus, upon rotation of first external ring <NUM>, the first seal <NUM> may be transitioned from a closed, liquid tight sealing position at <NUM> to an open position at <NUM>. The other seals, including second seal <NUM> and third seal <NUM>, may be configured similarly to include engagement between spokes <NUM> and an inner surface of corresponding external rings, with a material <NUM> of the seals coupled to spokes <NUM>. As can be seen, mixing is allowed to occur between liquid stored in liquid chamber <NUM> and supplements or other mixers stored in first chamber <NUM> when the first seal is transitioned to an open position at <NUM>.

Turning to <FIG> shows an alternative exterior for a twenty-second example container <NUM>. As can be seen with the alternative exterior at <FIG>, twenty-second example container <NUM> includes a lid <NUM> and a base <NUM> that differ from the previously introduced example containers. Lid <NUM> and base <NUM> are substantially circular in shape. Lid <NUM> comprises a first section 2202a, a second section 2202b, and a third section 2202c. The first section 2202a of lid <NUM> flares outward away from longitudinal axis <NUM> when moving in a direction away from base <NUM>. Longitudinal axis <NUM> is a longitudinal axis of twenty-second example container <NUM>. Thus, a circumference of first section 2202a at an end closest to base <NUM> is smaller than a circumference of the first section 2202a at an end furthest from base <NUM>. The second section 2202b of lid <NUM> is positioned between the first section 2202a and the third section 2202c. The second section 2202b has a substantially constant circumference. The side walls of the second section 2202b are substantially parallel to the longitudinal axis <NUM>. The circumference of second section 2202b is a same circumference as at the end of the first section 2202a furthest from base <NUM>. The third section 2202c of lid <NUM> tapers inward towards a longitudinal axis <NUM> when moving in a direction away from base <NUM>. Thus, a circumference of the third section 2202c at an end closest to base <NUM> is larger than a circumference of the third section 2202c at an end furthest from base <NUM>.

Base <NUM> flares outward away from longitudinal axis <NUM> when moving in a direction away from lid <NUM>. Base <NUM> includes a first section 2204a and a second section 2204b. The first section 2204a and the second section 2204b both flare out away from longitudinal axis <NUM> when moving in a direction away from lid <NUM>. Thus, a circumference at the end of base <NUM> which forms an end of the twenty-second example container <NUM> larger than the remainder of the base. It is noted that the second section 2204b is steeper than the first section 2204b. Twenty-second example container <NUM> further includes a second shaft <NUM> that extends parallel to the longitudinal axis <NUM>. Shaft <NUM> and second shaft <NUM> each are coupled to twenty-second example container <NUM> via a plurality of connection points <NUM>. The shaping of the alternative exterior shown at <FIG> may help to prevent tipping of the container.

Turning to <FIG> shows views <NUM>, <NUM>, and <NUM> for a twenty-third example container. As may be seen in view <NUM> of <FIG>, rather than utilizing seals as previously disclosed herein, stack separators may be included. These stack separators comprise a first disk <NUM> and a second disk <NUM> that are positioned between the chambers. The first disk <NUM> and the second disk <NUM> may be rotated relative to one another to adjust an amount of opening overlap (and thus amount of communication) allowed between chambers. In at least one example, an entire chamber may be rotated to rotate the first disk <NUM> relative to the second disk <NUM> included between each of the two adjacent chambers. For example, first chamber <NUM> may be rotated to adjust the disk positioning. Additionally, third chamber <NUM> may be rotated to adjust the disk positioning.

Turning to <FIG> shows a twenty-fourth example container <NUM> and <FIG> shows a twenty-fifth example container <NUM>. In at least one example, <FIG> may be alternative view of the same container. As seen in <FIG>, a stacking configuration is shown, where the chambers are coupled via coupling threads. Further, a lid <NUM> forms an entire top surface of the containers in <FIG>. External rings in <FIG> are included. In at least one example, the first external ring <NUM>, second external ring <NUM>, and third external ring <NUM> in <FIG> may rotate a first disk relative to a second disk to vary an alignment of openings in the disks and adjust communication between the chambers. The disks may be first disk <NUM> and second disk <NUM>, in at least one example.

Turning now to <FIG>, a twenty-sixth example container <NUM> is shown, and at <FIG>, a twenty-seventh example container in a first position <NUM> is shown and the twenty-seventh example container in a second position <NUM> is shown. The twenty-sixth example container <NUM> may be the same container as shown in <FIG> in at least one example. <FIG> are described together below.

As may be seen at <FIG>, first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> are vertically stacked within a first cylindrical structure <NUM>, with dividers dividing each of the chambers. Moreover, an opening <NUM> extends vertically across each of the chambers, the opening formed into the cylindrical structure. Additionally, a second cylindrical structure <NUM> is shown with a diameter that is slightly larger diameter of first cylindrical structure <NUM>. In this way, the first cylindrical structure <NUM> may be nested in the second cylindrical structure <NUM> with a relatively tight fit while still allowing rotation of the first cylindrical structure <NUM> relative to the second cylindrical structure <NUM>.

The second cylindrical structure includes a first opening <NUM>, a second opening <NUM>, and a third opening <NUM> (see <FIG>). Each of the first opening <NUM>, second opening <NUM>, and third opening <NUM> are sized and positioned such that, upon positioning first cylindrical structure <NUM> within second cylindrical structure <NUM>, the first opening <NUM>, second opening <NUM>, and third opening <NUM> align with first chamber <NUM>, second chamber <NUM>, and third chamber <NUM>, respectively.

A positioning tube <NUM> may extend from a top surface of the first cylindrical structure <NUM>. The chamber positioning tube <NUM> may fit into a lid positioning tube <NUM>, which extends downward from chamber adjustment mechanism <NUM>, which is positioned on the lid.

By positioning the first cylindrical structure <NUM> within the second cylindrical structure <NUM>, and coupling the chamber positioning tube <NUM> with the lid positioning tube <NUM>, rotation of the chamber adjustment mechanism <NUM> may result in rotation of first cylindrical structure <NUM> relative to second cylindrical structure <NUM>. As the first cylindrical structure <NUM> is rotated relative to second cylindrical structure <NUM>, the chambers are exposed by openings in the second cylindrical structure <NUM> one at a time. In order to indicate which chamber is being exposed as the chamber adjustment mechanism is rotated, indicia <NUM> may be included on top of the lid. If the chamber adjustment mechanism <NUM> is rotated to point at "<NUM>," for example, then the cylindrical structures are positioned such that the third chamber <NUM> is exposed. It is noted that the first cylindrical structure <NUM> and second cylindrical structure <NUM> are positioned within a liquid chamber, such as a bottle (not shown). The lid is further coupled to the liquid chamber. Thus, exposure of the chambers enables mixing of any supplements that may be stored in the chambers with liquid that may be stored in the liquid chamber.

Thus, disclosed herein is a container and methods. The container may comprise a first chamber that is positioned between a liquid chamber and a second chamber, a first seal that is positioned between the first chamber and the liquid chamber, and a second seal that is positioned between the second chamber and the first chamber. By rotating a first external ring of the container that is positioned between the liquid chamber and the first chamber of the container a first liquid tight seal is opened to enable communication between the liquid chamber and the first chamber. The first external ring may be positioned at a first end of the liquid chamber that is opposite a second end of the liquid chamber that includes a drinking opening. Similarly, rotation of a second external ring positioned between the second chamber and the first chamber may open a second liquid tight seal to enable communication between the second chamber, the first chamber, and the liquid chamber.

Turning now to <FIG>, further example containers are shown, including twenty-eighth example container <NUM>, twenty-ninth example container <NUM>, and thirtieth example container <NUM>. In at least one example, the example containers shown in <FIG> may be various views of the same container.

<FIG> shows a twenty-eighth example container <NUM> including a lid <NUM> with an opening positioned therein. As seen at <FIG>, lid <NUM> includes threading for coupling purposes. In addition to lid <NUM>, <FIG> shows a top divider <NUM> which fits onto multi-chamber housing <NUM>, where multi-chamber housing <NUM> includes first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> contained therein. The first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> are separated via dividers positioned inside of multi-chamber housing <NUM>. It is further noted that top divider <NUM> includes projections on a bottom surface to create a tight fit with multi-chamber housing <NUM>. The projections on the bottom surface of top divider <NUM> are shown at least at <FIG>.

As seen in <FIG>, multi-chamber housing <NUM> includes a plurality of valves. In particular, each of first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> includes a valve positioned in a bottom thereof. In particular, first chamber <NUM> includes a first valve <NUM>, second chamber <NUM> includes a second valve <NUM>, and third chamber <NUM> includes a third valve <NUM>. The multi-chamber housing <NUM> further includes a shaft receiving opening <NUM> for receiving shaft <NUM> of chamber outer sleeve <NUM>, when multi-chamber housing <NUM> is positioned within chamber outer sleeve <NUM>. The first valve <NUM>, second valve <NUM>, and third valve <NUM> are accessible from an exterior of the container upon positioning the multi-chamber housing <NUM> within chamber outer sleeve <NUM>. The first valve <NUM>, second valve <NUM>, and third valve <NUM> may be used to adjust openings in a bottom of their respective chamber. For example, as seen in <FIG>, second valve <NUM> may be used to adjust a second chamber opening <NUM>. Third valve <NUM> may be used to adjust a third chamber opening <NUM>. Should one or more of the valves be used to transition a chamber opening to an open position, communication may be enabled between the chamber and liquid chamber <NUM>. It is noted that a mixing element <NUM> is positioned between the first chamber <NUM>, second chamber <NUM>, and third chamber <NUM> to improve mixing.

Turning now to <FIG>, an example method for a container comprising multiple chambers <NUM> is disclosed. Step <NUM> of method <NUM> includes closing inter-chamber seals. Closing the inter-chamber seals includes creating liquid tight inter-chamber seals, as has been discussed above. For example, the first seal <NUM>, second seal <NUM>, and third seal <NUM> may be closed via rotation of corresponding first external ring <NUM>, second external ring <NUM>, and third external ring <NUM>.

As another example, disks, such as first disk <NUM> and second disk <NUM>, may need to be rotated relative to one another to ensure their openings are not aligned to close the inter-chamber seals. As a further example, valves may need to be moved to a closed position to close the inter-chamber seals. For example, first valve <NUM>, second valve <NUM>, and third valve <NUM> may need to be set to a position which closes corresponding chamber openings (such as third chamber opening <NUM> and second chamber opening <NUM>). Alternatively, in cases where a first cylindrical structure is being fit within a second cylindrical structure to form seals (such as first cylindrical structure <NUM> being fit within second cylindrical structure <NUM>), inter-chamber seals may not need to be closed.

Following step <NUM>, method <NUM> may include loading dry and liquid products into separate chambers of a container at step <NUM>. In at least one example, loading the dry and liquid products into separate chambers may include rotating one or more chambers about a shaft to enable access to the chambers. Additionally or alternatively, a cover (such as a lid) of the chambers may need to be removed.

In one or more examples, the dry products may be multiple different supplements, and each of these multiple different supplements may be loaded into different chambers. For example, a first supplement may be loaded into a first chamber, a second supplement may be loaded into a second chamber, and a third supplement may be loaded into a third chamber. Liquid may further be loaded into a liquid chamber. The first chamber, second chamber, third chamber, and liquid chamber are all part of the same container. The first chamber, second chamber, third chamber, and liquid chamber may correspond to any one or more of the example containers disclosed herein. In at least one example, the supplements may be loaded into the chambers as discussed at <FIG>. As the inter-chamber seals have been closed, the dry products may be kept separate and dry from any liquids and other dry products within the container.

Loading the dry and liquid products into separate chambers may include aligning and locking the chambers in an aligned formation. For example, the chambers may be aligned such as shown in <FIG>, and the locking mechanisms <NUM> and/or the switch <NUM> may be transitioned to a locked stated.

It is noted that in a case where the container comprises the cylindrical configuration discussed above, loading the dry and liquid products into separate chambers of the container may include loading supplements into each of the first chamber, second chamber, and third chamber of the first cylindrical structure. Then, the first cylinder is positioned within the second cylindrical structure such that all openings of the second cylindrical structure are offset from the opening exposing the chambers of the first cylindrical structure. The nested first and second cylindrical structures are then positioned within a liquid chamber and coupled to the lid of the container via positioning tubes, where the liquid chamber contains liquid therein.

Once the dry and liquid products are loaded into separate chambers of the container, a first seal is opened via rotation to enable communication between a liquid chamber and a first chamber at step <NUM>. In at least one example, rotation may include rotation of a first external ring, as discussed at <FIG>. By rotating the first external ring, the first seal between the liquid chamber and first chamber is transitioned from a closed position to an open position. In at least one example, a pre-workout supplement may be loaded in the first chamber. Thus, the liquid chamber and the pre-workout supplement in the first chamber may be mixed via opening the first seal.

In one or more examples, rotation may include rotation of a chamber itself, such as in the disk configuration. In at least one example, rotation may include rotation of a valve for a first chamber. In one or more examples, one of a first cylindrical structure and a second cylindrical structure may need to be rotated in order to open a first seal to enable communication between a liquid chamber and the first chamber.

At <NUM>, method <NUM> includes opening a second seal via rotation to enable communication between the liquid chamber and a second chamber. In one or more examples, a supplement to be taken during a workout may be stored in the second chamber.

Rotation to open the second seal may include rotation of a second external to open a second seal, as discussed above. In one or more examples, rotation may include rotation of a chamber itself, as in the disk configuration. In at least one example, rotation may include rotation of a valve for a second chamber. In one or more examples, one of a first cylindrical structure and a second cylindrical structure may need to be rotated further in order to open a second seal and enable communication between a liquid chamber and the second chamber.

In cases where the first chamber is positioned between the second chamber and the liquid chamber, the seal opened to enable communication between the first chamber and the liquid chamber may be maintained open at step <NUM>.

At <NUM>, method <NUM> includes opening a third seal via rotation to enable communication between the liquid chamber and a second chamber. In one or more examples, a supplement to be taken post-workout may be stored in the third chamber.

Rotation to open the second seal may include rotation of a third external to open a third seal, as discussed above. In one or more examples, rotation may include rotation of a chamber itself, as in the disk configuration. In at least one example, rotation may include rotation of a valve for a third chamber. In one or more examples, one of a first cylindrical structure and a second cylindrical structure may need to be rotated further in order to open a third seal and enable communication between a liquid chamber and the third chamber.

In cases where the first chamber and second chamber are positioned between the third chamber and the liquid chamber, the seal opened to enable communication between the first chamber and the liquid chamber and the seal opened to enable communication between the second chamber and the liquid chamber are maintained open at step <NUM>.

In this way, the container disclosed herein enables easy and efficient use of multiple supplements at different points in time. Moreover, the technical effects of improved dry storage and compact dimensions of the multi-chambered container are achieved for the use of multiple, different supplements (especially supplements that are in powder form). Further, the container disclosed herein enable varied supplement to liquid ratios to be used, improving a flexibility and capacity of the disclosed container to create different supplement mixtures. Additionally, in examples where a mixing element may be included as disclosed herein, advantages as to improved mixing of supplements and liquids may be achieved.
