DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
(12) Referring now to the drawings of FIGS. 1-10, are the modes of the device 10 employed for the transport, containment, mixing and dispensing or drinking of a mixed-beverage of the liquid housed in a first compartment 12 of the container 11 and the mixture housed in a second compartment 14. FIG. 1 depicts the device 10 in one preferred embodiment that includes a first or liquid compartment 12 in operative engagement with a solute or second compartment 14. A communicating pathway therebetween is separated by a valve 16 to prevent the premature mixing of each compartment's respective contents.
(13) The valve 16 in this mode is shown seated within a resting structure 18 in a closed state blocking communication between the first and second compartment, and supported by an inverting spring 20. The inverting spring shown may be made of stainless steel, spring steel, or plastic in various forms. The inverting spring 20 may also be replaced by various shapes and forms as shown in FIG. 4 where it takes on the form of an inverting and amalgamating dome spring mechanism 22 to accomplish other goals such as the improved mixing of solutes 24 and liquids 26.
(14) The inverting spring 20 shown in FIGS. 1, 2, 3 and 5 enables the liquid compartment 12 to remain isolated from the solute compartment 14 until a time of desired mixing. The valve 16 may translate away from an aperture communicating with the first compartment 12 to fully and instantly open communication between both compartments, through an impact of the padded base 28 upon a surface.
(15) In some modes of the device, the valve 16 mechanism can be activated incrementally, and opened and sealed sequentially, by the squeezing and compressing of the first compartment walls 30 as shown in FIG. 2. Such compression causes a temporary pressurization increase in the first compartment 12 and opens the valve mechanism to allow a short duration of mixing of the fluid in the first compartment 12, with the mixture in the second compartment, allowing the user to determine the amount of mixture which is communicated back into the liquid in the first compartment 12 to make a stronger or weaker mix. This allows the device to be refilled once the original supply of fluid in the first compartment 12 has been consumed, and the process repeated in this sequential short mixing mode. In other modes the valve 16 may be included in an insertable cartridges 17 defining the second cavity 14 and would be replaced with each new cartridge 17 inserted.
(16) In the valve mechanism of FIGS. 1,2, 3 and 5 there is also illustrated a dampening component 32 located between the inverting spring 20 and the valve's resting structure 18. The dampening component 32 in FIGS. 1 and 5 appear compressed relative to other figures due to the valve 16 being closed and the corresponding inverting spring 20 pressing the dampening component 32 against the valve's resting structure 18.
(17) This dampening component 32 slows the closing and sealing action of the valve 16 after the liquid compartment walls 30 have been compressed and the valve 16 has been actuated as shown in FIG. 2. Shown in FIG. 2 is the dampening component 32 no longer compressed due to the increase in separation between the inverting flat spring 20 and the valve's resting structure 18. The compression or contraction of the dampening component 32 when the walls 30 are squeezed to impart pressure into the device, enables a slowed closing by providing a resistance bias to the inverting flat spring 20 as the dampening component 32 compresses, while also allowing a small amount of fluid which was squeezed through from the solute compartment, to return.
(18) The dampening and slow-closing action and expansion of the dampening component once compression to the sidewalls ceases, enables the device 10 as noted to “burp,” or sequentially mix small portions of the liquid 26 with small portions of solute 24. This “burping” or temporary mixing is shown in FIG. 2 and enables the user to obtain small amounts of the solute 24 in the liquid 26, which is desirable with concentrated additives. As noted, this action also enables a user to mix small amounts and consume them, and subsequently refill the liquid compartment 12 multiple times with an easily accessible fluid such as water before needing to replenish the solute 24 while still enjoying the solute flavors or supplement benefits.
(19) In all figures the device 10 is shown with a dispensing nozzle 34 affixed to the domed peak of a removable lid 36. This nozzle should be formed in such a way that an opening due to internal pressure will not occur during a compressive biasing of the compartment walls 30.
(20) FIG. 3 depicts the device 10 where the inverting spring 20 is inverted and the valve 16 mechanism is thereby locked open. This open-valve mode occurs after the base 28 has impacted a solid surface, thereby transferring the kinetic energy of the device through the liquid 26 and against the surface of the valve 16. That transfer of energy applies a significant biasing which is relational to the surface area of the valve 16 and overcomes the biasing force of the spring forcing the valve 16 to an open position. As expected in this mode, the dampening component 32 does not appear to be compressed as this is the maximum space allowable between the inverting flat spring 20 and the valve's resting structure 18. In this mode, the solute 24 and liquid 26 mix into a solution and become the desired mixed beverage that is ready for consumption.
(21) Shown in FIG. 4 is the device 10 with a replacement component for the inverting spring 20. In this embodiment, an inverting and amalgamating dome-spring mechanism 22 is present to provide resistance biasing to the valve 16 toward sealing the first chamber from the second, as well as facilitate the mixing of solutes 24 and liquids 26 upon impact and translation of the spring. In this embodiment, the dampening component 32 mentioned previously is not shown, but may take on the form of an air cushion-donut or ring-like gasket due to the shape of the inverting and amalgamating dome-spring mechanism 22. Also, the space between the webbing of the inverting and amalgamating dome-spring mechanism 22 allows fluid solutions to pass through while creating turbulence during device 10 shaking, thereby assisting in the amalgamation of the solute 24 and liquid 26. This action helps to prevent dry chunks from remaining in the solution when a powdered solute 24 is used.
(22) If the amalgamating properties of the inverting and amalgamating dome-spring mechanism 22 are only sometimes desired, an embodiment shown in FIG. 5 illustrates a removable amalgamating webbing 36 that may clip into the device 10. This amalgamating webbing 36 may be used in conjunction with the more simple inverting flat spring 20, and should accomplish the same mixing functions as the inverting and amalgamating dome-spring mechanism 22.
(23) FIG. 5 also depicts the device 10 with all components separated in an exploded view. This illustrates that different components may be mated through the employment of complimentary threaded surfaces 38, and the components should be interchangeable. This interchangeability enables a user to omit the valve 16 and solute compartment 14 by attaching the padded base 28 directly to the liquid or first compartment 12. It also shows that the solute housing second compartment 14 can be treated as an individual container if a mating lid is attached to its complimentary threaded surface. Padded base 28 components may act as a mating lid in this circumstance. This enables a user to carry multiple solute compartments 14 with different solutes 24 for attachment to a single liquid compartment 12.
(24) In FIG. 6 shown a particularly preferred mode of the device 10, having a second compartment 14 formed by a cartridge, which is removably engageable to the device 10 and later disposable. Such will allow users to buy the mixture prepackaged in the cartridge forming the second compartment 14 which would be provided sealed therein and will allow for commercial sales in stores and for instance in vending machines. The cartridges can be sold or dispensed having onboard valves 16 engaged to the cartridge defining the sealed second compartments 14, and may have any of a plurality of different mixes housed therein for different purposes when mixed with the liquid of the first compartment 12. Upon finishing use of the mixture in the cartridge defining second compartment 14, it may be disposed and replaced with another. Of particular note is that having the valve 16 engaged with the cartridge allows for replacement of the valve 16 with each cartridge change. Of course the second compartment 14 if formed of an engageable cartridge, might also be refilled and resealed.
(25) As shown, the pressure activated valve mechanism 16 in this mode employs a pressure activated dual flow valve 16 mechanism to provide communication of fluid between the second compartment 14 and first 12. The valve 16 engaged between the first and second compartment 14 is pressure activated to open and allow flow in either direction, but toward the compartment with lowest pressure until such is normalized. In this mode when force is imparted to the first compartment 12, fluid is forced into the removable second compartment 14 or cartridge. Upon cessation of compression of the first compartment 12, suction is generated by the collapsed walls returning to a normal position which helps cause the return of fluid mixed with concentrate in the second compartment 14 to the first compartment 12. Stored pressure can also be employed to induce the reverse flow from the second compartment 14 to the first in combination with the suction formed therein.
(26) As shown, a deformable wall 15 of the second compartment or cartridge may be elastic and employed to store pressure energy. Once pressure from the first compartment 12 ceases, and suction forms in the first compartment 12, the wall 15 contracts to an un-stretched position thereby imparting higher pressure into the second compartment 14 than the first, thereby causing communication of fluid therein to the first compartment 12 through the valve 16 mechanism. In this removable and replaceable cartridge mode of the second compartment 14, the valve 16 is continually replaced and helps avoid contamination from food or material which may become lodged in the valve 16. While it should be in now way considered limiting, shown in FIG. 6a is an example of a pressure-actuated dual-flow valve 16. While any such valve which substantially ceases communication between two compartments when pressure in both are substantially equal can be employed, the example in FIG. 6a shows the operation of such simple and inexpensive valves.
(27) The valve 16 has a first position shown as the closed mode where flaps formed by slits in a flexible plastic or polymeric sheet are substantially in contact with each other along perimeter edges. In first position or the closed mode, fluid communication is substantially prevented between the two compartments on either side of the valve 16. Also shown is a second position of the valve 16 allowing flow from the compartment with the highest pressure, toward the compartment with the lower pressure which as shown can be in either direction deponing on the relative pressure differential between the two compartments.
(28) The valve 16 in the mode of the device 10 with permanent first and second compartments may be engaged therebetween. In the preferred mode of the device 10 employing replaceable cartridges for the second compartment 14, the valve 16 may be engaged with the cartridge to allow the user to renew the valve 16 with each new cartridge which will be a significant improvement over current devices where internal valves can become contaminated with grime and germs and bacteria if left unwashed after use.
(29) By substantially prevented is meant that none or minor amounts, such as fractions of a milliliter, will communicate across the closed valve 16. The other two modes of the valve 16 show fluid flowing away from the valve in a direction away from the compartment with the higher pressure. Such will occur when the bottle is compressed to communicate fluid past the valve into the second compartment 14 or disposable cartridge.
(30) This flow will reverse when compression of the first compartment ceases, causing a suction to develop from the walls moving to the uncompressed position and dropping pressure, and pressure in the second compartment 14 or cartridge becoming higher, due to elastic walls of the disposable cartridge, or a flexible membrane in the second compartment 14 storing the pressure energy which rebounds upon cessation of compression of the first compartment. In this fashion a pressure actuated dual flow valve 16 providing the valve mechanism between the compartments, allows the fluid under higher pressure from the first compartment to mix with concentrate in the disposable cartridge or second compartment 14, and return the mixture to the fluid in the first compartment upon cessation of compression thereof which lowers the pressure in the first compartment lower than that of the second compartment 14.
(31) Of course those skilled in the art will realize, that any pressure actuated dual flow valve 16 can be employed to regulate the flow in the container 11 between the first compartment and second compartment 14, to allow more or less concentrate from a cartridge or second compartment 14 to be mixed with the fluid in the first compartment. As such, any such valve which will provide flow in-between the two compartments in a direction from higher pressure to lower pressure, and substantially eliminate such fluid communication when pressure between the two compartments is equal, is anticipated within the scope of this application and claims.
(32) There is seen in FIG. 7 a mode of the device 10 having another configuration of a container 11 having a replaceable and disposable second compartment 14 such as an engageable cartridge 17 as shown in FIGS. 7-10. As depicted for illustration purposes only, and in no manner limiting on dimensions or shape of the engageable second compartment 14, there is shown a “K-cup” dimensional configuration of a cartridge 17 which may be formed with elastic walls, which will be easily manufactured due to widespread use of such a configuration for coffee makers and the like. This mode may include the valve mechanism 16 such as in FIG. 6 if the body of the second compartment 14 is elastic in nature. Or, it may be configured to engage with a one way valve as shown, or with a valve 16 system positioned in an aperture in the cartridge itself which opens in reaction to fluid communication for a time duration, or pressure generated by compressing the sidewalls, or both.
(33) As shown in FIG. 8, the container 11 of the device 10 can employ cartridges 17 to provide an engageable second compartment 14 of the device 10 wherein the engageable cartridge 17 defining the second compartment 14 has a pressure-openable or liquid-openable seal engaged around an aperture 23 providing the valve 16. The aperture end of the cartridge 17 is positionable into the lower end of the first compartment 12 defining the fluid reservoir of a closeable container 11 housing. In this mode of the device 10, squeezing the flexible sidewalls will communicate pressure to the first compartment 12 and against the seal 16 in the cartridge 17 mode of the second compartment 14 such that it will either peel pack in its adhesive engagement, or rupture, or otherwise allow communication of fluid freely between both the first compartment 12 and the second compartment defined by the cartridge 17.
(34) FIG. 9 shows the device of FIG. 8 wherein pressure from squeezing the sidewalls, or communication with the fluid for a duration of time, has caused an opining between the body of the cartridge 17 and foil or aperture cover forming the valve 16 of the cartridge 17 defining the second compartment 14, such that the concentrate 21 within the cartridge 17 defining the second compartment 14, freely mixes with the fluid from the first compartment 12 through an open aperture 23. In all modes where a cartridge 17 is employed as the second compartment 14, it is engaged operatively through a passage, and/or positionable in a complimentary dimensioned cavity 39 within a removably engageable lower housing 41 or the like, to hold it in place until the valve 16 formed in the endwall of the cartridge 17 is ruptured, separated, or otherwise opened by one or a combination of pressure in the first compartment 12 or fluid communication which dissolves adhesive holding the closure 25 sealed over the aperture 23 in the cartridge 17 sidewall.
(35) FIG. 10 depicts the device 10 employing an open end fluid container 11 such as a glass or large cup, and showing the opened cartridge 17 aperture 23, caused by fluid communication therewith and/or pressure against the closure 25 of the aperture 23 from squeezing the flexible sidewalls forming the first compartment 12 of the container 11 with an engageable lid (not shown) attached to the edge at the open end. A complimentary cavity 39 is formed to accept and seal against the edge of the cartridge 17 to hold it in place as earlier shown and described. Deformable walls 26 can be formed in the sidewalls of the container 11 by positioning an air cavity 31 therein. Alternatively, the two-way valve 16 form FIGS. 6 and 8, may also be employed within the aperture 23 as with other modes of the device 10 herein using the closure 25, when a permanent opening is not desirable with continuous mixing, and where sequential mixing of fluid and concentrate based on compression of the first compartment is desirable to allow the user a means to increase or decrease the mix of concentrate 21 with the fluid based on the number of compressions.
(36) While all of the fundamental characteristics and features of the liquid mixing and transport device herein have been shown and described herein, with reference to particular embodiments thereof, a latitude of modification, various changes and substitutions are intended in the foregoing disclosure and it will be apparent that in some instances, some features of the invention may be employed without a corresponding use of other features without departing from the scope of the invention as set forth. It should also be understood that various substitutions, modifications, and variations may be made by those skilled in the art without departing from the spirit or scope of the invention. Consequently, all such modifications and variations and substitutions are included within the scope of the invention as defined by the following claims.
