Description




FIELD OF THE INVENTION




This invention relates to dilution systems and methods for concentrated detergents. More specifically, the invention relates to a system and method for dilution of a concentrated detergent independent of external power.




BACKGROUND OF THE INVENTION




Typical liquid detergents are purchased in diluted, ready-to-use form. The practice is convenient and customary for typical users. However, a significant portion of the purchase price of the ready-to-use detergent is due to the costs of the packaging, storage and shipping weight. The resulting costs become problematic as the distance increases from the manufacturing facility to a point of use.




Servicing remote areas are especially problematic. For example, the expense of transporting the bulk and weight of ready-to-use detergents to third world countries is sometimes prohibitive, especially when the standard of living is lower than the country from which the goods are manufactured. One solution is to manufacture the goods in the particular country. This option is often prohibitive in itself due to the costs of creating a manufacturing facility of tens or hundreds of millions of dollars. Even if the manufacturing is done in an industrial area in that country, transporting the ready-to-use detergents to remote areas of the particular country can still be expensive.




Therefore, there remains a need to supply ready-to-use detergents that minimizes the bulk and weight to the user, but also allows transporting the detergent in a concentrated form to avoid the shipment of large quantities of water.




SUMMARY OF THE INVENTION




The present invention provides a solution to the problem of reducing the bulk and weight of detergents for delivery to users by providing in at least one embodiment an in situ, discrete, batch mixing method and system for a diluent and concentrated detergent at a point of dispense. While some systems are designed to mix diluents and detergents, those systems are typically designed for continuous flow, for example, in a manufacturing facility. The present invention provides for mixing the diluent and detergents in discrete batches sized for a user at the point of dispense, using a method and system that can be located even in remote areas without an external power supply. The system and method only needs diluent line pressure in at least one embodiment. Further, the method and system controls access to the batch quantity so that multiple batches are not unintentionally extracted. The method and system can be used with vending machines placed on site.




The present invention provides in at least one embodiment a batch quantity system with a filling machine for mixing and dispensing a super concentrated detergent with a diluent, comprising a diluent supply having a line pressure; a detergent container containing concentrated detergent to form a detergent supply; a control valve adapted to control a flow of a batch quantity of the diluent supply, the concentrated detergent, or a combination thereof, the valve operated independent of an external power supply; an eductor coupled to the diluent supply and the concentrated detergent supply and adapted to receive the pressurized diluent and cause a corresponding flow of the concentrated detergent to form a combined flow of the diluent and the detergent; a static inline mixer coupled to the eductor to mix the combined diluent and detergent; a fill container disposed downstream of the eductor to receive a predetermined quantity of the combined diluent and detergent; and an outlet of the fill container adapted to flow the combined diluent and detergent into a removable container.




The present invention also provides in at least one embodiment a method for mixing and dispensing a batch quantity of super concentrated detergent with a diluent, comprising providing a diluent at a pressure to create a diluent supply; providing a detergent container containing concentrated detergent to create a detergent supply; coupling a flow of each of the diluent supply and detergent supply to an eductor; flowing a quantity of the diluent and the detergent through the eductor to create a combined flow of diluent and detergent; flowing the combined flow through a static inline mixer; flowing the combined flow into a fill container to create a predetermined quantity of the combined diluent and detergent; stopping the combined flow of the diluent supply and detergent supply into the fill container; and dispensing an output of the combined flow.




The present invention also provides a batch quantity system with a filling machine for mixing and dispensing a super concentrated detergent with a diluent, comprising a diluent supply having a line pressure; a detergent container containing concentrated detergent to form a detergent supply; a control valve adapted to control a flow of a batch quantity of the diluent supply, the concentrated detergent supply, or a combination thereof, the valve operated independent of an external power supply; an eductor coupled to the diluent supply and the detergent supply and disposed downstream of the control valve, the eductor adapted to receive the pressurized diluent and cause a corresponding flow of the concentrated detergent to form a combined flow of the diluent and the detergent; a static inline mixer coupled to the eductor to mix the combined diluent and detergent; a fill container disposed downstream of the eductor and adapted to receive a predetermined quantity of the combined diluent and detergent based on an automatic operation of the control valve and on a predetermined level of diluent and detergent in the fill container; an outlet of the fill container adapted to flow the combined diluent and detergent into a removable container; and an outlet valve coupled to the outlet and adapted to remain open after actuation until a quantity of the combined diluent and detergent flows out of the fill container and to automatically close after the quantity has flowed out.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

is a schematic perspective view of a discrete batch quantity system with a filling machine. In general, the batch quantity system


8


includes various internal and external elements, such as a filling machine


10


having a fill container


12


with a detergent container


14


coupled to the fill container


12


and various controls. The filling machine dispenses product in response to one or more selections that are input into the machine by a user. The filling machine


10


can be provided in the form of a “vending machine.” In this application, the term “vending machine” is meant to include a filling machine that can be operated by coin, token, card, or other suitable means of compensation or control.




The filling machine


10


can be disposed at a location that is accessible to a user and can mix the diluent and detergent on site at the point of dispense, that is in situ, to the user. As described below, the filling machine


10


can operate independent from an external power supply. Thus, the filling machine


10


can be located at remote sites that may not be supplied with such external power supply, that is, without electrical, solar, pneumatic, nuclear, or other common power sources. An “external power supply” does not include use of manual power such as from a human, line pressure from a diluent supply, or gravity, described below.




In addition to the detergent container


14


, the system


8


includes a diluent supply


16


fluidicly coupled to the fill container


12


with an outlet


18


coupled thereto. The outlet


18


is adapted to allow a quantity of the diluent and detergent mixture to exit the fill container


12


. The outlet


18


can dispense the mixture into a removable container


22


, such as provided by the filling machine or by a user. Advantageously, an opening


20


can be provided for the convenience of the user to insert the removable container


22


, if desired. The internal and external structures that are associated with the filling machine


10


in at least some embodiments are described in reference to

FIGS. 2-4

.




The system


8


can also include a start controller


24


which in at least one embodiment is a manually operated mechanical device. This feature further allows the system to operate independent of an external power supply. In other embodiments, the start controller


24


can be operated by a diversion of the diluent supply


16


with its line pressure and a switch (not shown) to control the start controller. The start controller


24


is coupled to various elements within the system


8


, to be described below that actuate the system. One or more compensation elements


26


, such as coins, tokens, cards, and other numismatic or control items can be used in connection with the start controller


24


to control the access and output of the mixture through the outlet


18


. Further, a selector controller


28


can be used to select various additives or other features in the combination of the diluent and the concentrated detergent.




Advantageously, the shipment of the detergent container


14


containing concentrated detergent reduces the bulk, weight, and therefore expense, of transporting diluted packaged liquid detergent to various locations, including remote areas. In at least one embodiment, the line pressure from the diluent supply


16


, controlled by manual actuation and supplemented by gravity, is the primary way to uniquely combine the flows into a relatively homogeneous mixture. Thus, the cost can be reduced in supplying ready-to-use detergent to the user with minimal external needs.





FIG. 2

is a schematic cross-sectional view of the discrete batch quantity system


8


. As described above, the system can include a fill container


12


, a detergent container


14


coupled thereto, and a diluent supply also coupled to the fill container


12


. The fill container


12


includes an outlet


18


disposed at an appropriate location on the fill container, so that a removable container


22


can receive a batch quantity of combined diluent and detergent. The term “coupled,” “coupling,” and like terms are used broadly herein and can include any method or device for securing, binding, bonding, fastening, attaching, joining, inserting therein, forming thereon or therein, communicating, or otherwise associating, for example, mechanically, magnetically, electrically, chemically, directly or indirectly with intermediate elements, one or more pieces of members together and can further include integrally forming one functional member with another. The coupling can occur in any direction, including rotationally.




The detergent container


14


generally includes a quantity of concentrate detergent


15


. The concentrated detergent can be a variety of formulations as may be suitable to the particular conditions in which the system is operated. For example, some formulations may be more suitable to colder climates. Without limitation, examples include mixtures containing a commercially available surfactant known as Neodol™ N45-7, commercial laundry detergents, generally in liquid form with low water content, and other formulations. Further, the detergents can include short chain alcohols and glycols, whitening agents, enzymes, and other components as should be known to those with ordinary skill in the art in the detergent field. Some formulations have gelling problems that are particularly associated with water mixed with detergent having high levels of surfactants. The embodiments described herein generally combine the diluent and detergent using an eductor and/or mixer to reduce the gelling problems.




The diluent supply


16


, generally water, can be provided at a given line pressure. The line pressure can vary from location to location. In at least one embodiment, it is believed that 30 pounds per square inch at gage (psig) can be used, although other line pressures, smaller and greater, can be used. The diluent supply


16


can include associated elements, such as a valve


32


, filter


34


, UV lamp


37


for disinfection, and pressure regulator


36


, known to those with ordinary skill in the art. For example, if the diluent supply is provided at 30 psig, the pressure regulated can reduce the pressure to 10 psig, for example and without limitation, and provide satisfactory mixing in at least one embodiment.




Similarly, the detergent container


14


can provide a detergent through a detergent supply


30


to the fill container


12


. The flow path between the detergent container


14


and the fill container


12


can also include similar elements as can be required for given installations, such as valves and filters (not shown). In general, the line pressure of the diluent supply


16


will be greater than the detergent supply


30


pressure, because generally the detergent supply will be operated by gravity in close proximity to the fill container


12


. Further, in other embodiments, the detergent container


14


can be located on level or below level of the fill container


12


, since the eductor described below creates a siphoning effect. It is anticipated that the detergent container


14


will be removably coupled to the fill container


12


as the detergent is replenished. Thus, it can be advantageous to include quick disconnect fittings and other appropriate elements between the detergent container


14


and the fill container


12


.




The diluent supply


16


and the detergent supply


30


from the detergent container


14


can be coupled to one or more control valves to control the respective flows into the fill container


12


. For example, the diluent supply


16


can be coupled to a control valve


38


and the detergent supply


30


can be coupled to a control valve


40


. However, it is to be understood that the control valves can function in unison and even be incorporated physically into a single unit. Still further, it can be useful to only control the flow of one of the fluids, while the other fluid responds to the first fluid flow. For example, the diluent supply can be controlled through the control valve and the detergent supply can respond to the diluent flow without a control valve for the detergent. Thus, the term “control valve” herein can include one or more valve units that control the diluent supply, the detergent supply, or a combination thereof.




One or more of the control valves can be selectively operated by an external input. In at least one embodiment, the external signal can be caused by a valve controller


42


, such as a float, that actuates a linkage


43


, to open and close the control valves


38


,


40


. The combined diluent and detergent


49


in the fill container


12


establishes a fluid level


48


at any given time. When the fluid level


48


rises to a predetermined level in the fill container


12


, the valve controller


42


rises to a point that shuts off one or more of the control valves


38


,


40


. For example, the control valves can operate to place a restriction over a seat (not shown) in the control valves.




An eductor


44


can be disposed in the system


8


downstream of the control valves


38


,


40


in at least one embodiment. The eductor allows diluent, such as water, to act as a siphoning mechanism to pull and entrain a dosage of detergent concentrate with the flow of diluent through an internal eductor cavity. The flow of diluent through the eductor causes a pressure drop as the fluid is forced through a venturi inside the eductor. The suction of the diluent siphons a dosage of detergent with each movement of the diluent through the venturi. The diluent's constant flow and suction allows a detergent concentrate to be dosed relatively rapidly and generally in a constant ratio of diluent-to-detergent, based on the diluent pressure and line restrictions.




Without limitation, eductors can be purchased from Fox Valve from Glover, N.J. in the United States. For example, a Fox liquid jet eductor part no. ½″ 121-WJE-CS has been found to provide 2.5 gallons per minute of water at 30 psig and 700° Fahrenheit to create a suction of up to 6 gallons per minute of detergent having a specific gravity of 1.1 at 0 psig and 70° Fahrenheit where the discharge was at 0.25 psig. It is to be understood that other eductors, other sizes, and other pressures are contemplated by the present invention and the above description is only exemplary.




Thus, in the embodiment shown, the diluent supply can be provided to one portion of the eductor and the detergent from the detergent supply provided to a second portion of the eductor. When the control valve


38


operates to allow the diluent to flow therethrough, the diluent also can flow through the eductor


44


. When the detergent supply is allowed to flow through the control valve


40


and into the eductor


44


, a generally consistent combination of diluent and detergent can exit therefrom.




One of the challenges in this art is a proper combination of the diluent and concentrate to avoid gelling and viscosity issues. To ensure a commercially satisfactory product, a static mixer


46


is generally included in the system


8


downstream of the eductor


44


. Generally, a static mixer does not require an external power supply to turn rotors and other movable parts. In some embodiments, static mixers use a stationary spiral winding. The diluent and detergent flow through the static mixer, and the winding causes a turbulent flow under force that relatively quickly breaks up the detergent concentrate gel into smaller particles which can rapidly dissolve in the diluent. Flow through the static mixer


46


can enter the fill container


12


and continue until a predetermined level is obtained, at which time one or more of the control valves


38


,


40


are closed.




It is to be understood that the sequence of the control valve(s), eductor, and mixer can be varied. For example, and without limitation, the control valve(s) can be located downstream of either the eductor


44


or the mixer


46


, so that flow through the eductor and mixer generally occurs when the valves are open.




The combined flow of diluent and detergent can be dispensed though the outlet


18


, described above. Some exemplary embodiments that can be used to dispense the diluent and detergent are shown in

FIGS. 2-4

. For example, in

FIG. 2

, the start controller


24


can be used to actuate the dispensing and can be manually operated. One or more linkages


50


,


52


,


54


and one or more pivot points


56


,


57


, as appropriate, couple the start controller


24


to an outlet valve


58


. The outlet valve


58


in the embodiment is disposed within the fill container


12


. However, it is to be understood that the outlet valve could be disposed external to the fill container


12


.




The outlet valve


58


can include a valve element


60


that can be raised and lowered in the fill container


12


. Advantageously, the outlet valve


58


can remain automatically open after actuation until a quantity of the combined diluent and detergent flows out of the container, independent of further actuation by the start controller


24


. The valve element


60


can automatically close after the quantity has flowed out of the fill container. In one embodiment, the valve element can include a flapper that would raise and remain in a raised position through flotation or other means until a quantity of the combined diluent and detergent flows out. The valve element


60


can be coupled, such as hingeably attached, to a support structure


62


, such as a post.




To further illustrate the actuation, a compensation element


26


, described in reference to

FIG. 1

, can be inserted into the start controller


24


. The start controller


24


can be manually actuated to move the linkages


50


,


52


and


54


. At least one of the linkages


50


,


52


,


54


raises the valve element


60


away from a sealing engagement with the outlet


18


. This action allows a quantity of the combined diluent and detergent to flow out of the outlet


18


and into the removable container


22


. The level


48


lowers in the fill container


12


until the valve element


60


can reseat itself on the outlet


18


. In the meantime, the start controller


24


can be reset independent of the status of the valve element


60


. Thus, it is advantageous for one or more of the linkages


50


,


52


, or


54


to be flexible or otherwise movable relative to the valve element


60


, so that the valve element


60


and the start controller


24


can be operated independently.




Optionally, additives can be supplemented to the diluent, detergent, or a combination thereof. Additives can include whiteners, fragrances, dyes, and other additional components. In some embodiments, it may be advantageous to include the additive in the flow stream prior to the static mixer


46


. In other embodiments, it can be suitable to supplement the additive into the combined flow after the static mixer, such as with additives that can rapidly disperse through an existing part of the fluid. Other places of supplementing the additives can also be determined depending on the particular application. In the embodiment shown, two separate lines are included, where one is added upstream of the static mixer


46


and the other downstream, although other positions and other quantities of lines could be used.




A selective controller


28


, also shown in

FIG. 1

, can be used to control the addition of the additives. For example, an additive actuator


64


can be actuated at a user's discretion to add certain additives. In one example, the additive actuator can include a push-button that traverses in or out from the selector controller


28


. Levers, toggles, and other actuators, known to those with ordinary skill in the art could be used. The additive actuators


64


can be coupled to a linkage


66


that is coupled to a dosing chamber


68


. For example and without limitation, the dosing chamber


68


can be an injector, a syringe, or other manual pump element. Advantageously, in consonance with other parts of system


8


, the dosing chamber


68


can be manually operated independent of an external power supply. An additive container


70


is coupled to the dosing chamber


68


. A one-way valve


72


, such as a check valve, can be disposed between the additive container


70


and the dosing chamber


68


. Alternatively, the one-way valve


72


can be incorporated into the additive container


70


or the dosing chamber


68


. Thus, when the dosing chamber


68


is actuated, the fluid contained in the dosing chamber is forced to go through an outlet


69


as opposed to returning through the inlet to the additive container


70


. The outlet


69


of the dosing chamber


68


can be coupled to a one-way valve


74


and in turn coupled to a conduit


76


. The conduit


76


can be coupled to the flow path of the diluent, detergent, or combined diluent and detergent.




A similar arrangement can be made for another additive. For example, an additive actuator


80


can be coupled to a linkage


82


, a dosing chamber


84


, and similarly to a second additive container


86


. The second additive container


86


can flow an additive through a one-way valve


88


into an inlet of the dosing chamber


84


. The dosing chamber


84


can pump a quantity of the additive through a one-way valve


90


into a conduit


92


and into the fill container


12


. Although not shown, it is to be understood that multiple additive containers can be included on one dosing chamber. If desired, the user can select between various additives by selective switches, diverter valves, and other selection means, known to those with ordinary skill in the art for such elements.





FIG. 3

is a schematic cross-sectional view of another embodiment of the system


8


. Similar elements are similarly numbered as described above. For example, the system


8


generally includes the fill container


12


coupled to a detergent container


14


and a diluent supply


16


. One or both of the diluent supply and detergent supply from the detergent container


14


can be controlled through one or more control valves


38


,


40


. The diluent and detergent can be combined by an eductor


44


and flow through a static mixer


48


to provide satisfactory mixing. Additives can be injected into one or more conduits


76


,


92


coupled to the fill container


12


or other portions of the system, as appropriate. The combined diluent and detergent can flow out of the fill container through the outlet


18


and into a removal container


22


.




An outlet valve


58


can control the dispensing of the combined diluent and detergent through the outlet


18


, similar to the outlet valve


58


described in reference to FIG.


2


. The outlet valve


58


includes a valve element


60


that can be translated axially comparing to rotatably, as previously above. The start controller


24


can actuate one or more linkages


50


,


52


, and


54


and one or more pivot points


56


,


57


. The linkage


54


can be comprised of multiple elements, such as linkages


54




a


and


54




b


. The linkages


54




a


and


54




b


may be slidably engaged with each other through a pin


96


and a slot


98


arrangement. For example, the slot can be formed in linkage


54




a


, and the pin


96


can be coupled to linkage


54




b


. The length of the linkage


54




a


,


54




b


can allow the pin to be disposed in the bottom portion of the slot


98


in an initially closed position of the valve


58


. When the linkage


54




a


is lifted by actuation of the start controller


24


, the linkage


54




a


can pull upward the linkage


54




b


. The movement can axially pull up the flapper element


60


of the valve


58


away from sealing engagement with the outlet


18


. The flapper element


60


can remain disengaged from the outlet


18


to allow the combined diluent and detergent


49


to flow through the outlet


18


into the removable container


22


. While the flapper element


60


is disengaged, the linkage


54




a


can be returned to a reset position, that is, lowered in the orientation shown in FIG.


3


. The lowering of the linkage


54




a


is independent of the position of the linkage


54




b


and the valve element


60


by allowing the pin


96


to slide in the slot


98


. A support structure


62


can be slidably coupled to the linkage


54




b


and the valve element


60


to provide lateral stability, if desired.





FIG. 4

is a schematic diagram of another embodiment of the system


8


. Similar elements are similarly labeled as described above and referenced in

FIGS. 1-3

. In this embodiment, some of the elements described above are external to the fill container


12


. For example, the detergent container


14


which includes a quantity of concentrated detergent


15


, is coupled to the eductor


44


external to the fill container


12


. Similarly, the diluent supply


16


is coupled to the eductor


44


also external to the fill container


12


. The fill container


12


can receive the combined flow of diluent and detergent from the eductor


44


to establish a predetermined quantity of combined diluent and detergent. In at least one embodiment, the predetermined quantity can be limited by the quantity that can flow into the fill container


12


. For example, a fill container


12


can be coupled to valve


17


that can function as an air release in combination with a fluid one-way valve, known to those with ordinary skill in the art for fluid systems. The valve


17


can allow air to enter and exit the fill container


12


. However, when the fluid rises to a certain level and seeks to exit the valve


17


, an internal float floats up to a seat to restrict the exit of the fluid. Thus, only a fixed quantity of the combined diluent and detergent can flow at any given time into the fill container


12


before the fill container is filled.




Further, the diluent supply


16


in an exemplary embodiment can be coupled to a valve


32


, a filter


34


, UV lamp


37


, a one-way valve


35


, a pressure regulator


36


, and the eductor


44


. In this embodiment, the valve


32


can function as a control valve


38


, described in reference to

FIGS. 2 and 3

. The valve


32


can be manually actuated in at least one embodiment.




The detergent container


14


can be used to flow detergent through a valve


102


into a prefill container


100


. The prefill container


100


provides a measured quantity of detergent prior to entrance into the eductor


44


. Further, valve


40


can be disposed downstream of the prefill container to act as a control valve for the entrance of the detergent into the eductor


44


. In at least one embodiment, the control valve


40


can be manually actuated.




A vent


104


can be coupled to either the detergent container


14


, the prefill container


100


, or both. The vent


104


can also be coupled to a drain line


106


. A valve


108


can be used to control the draining of the drain line


106


into the container


110


. Similar to the embodiment described above, one or more conduits


76


,


92


can be used to provide additives into the diluent, detergent, or both. In the embodiment shown, the diluent and detergent are combined through the eductor into the fill container


12


and the additives are provided subsequent thereto. Further, all the fluids are present prior to flowing through the static inline mixer


46


. The outlet of the combined diluent and detergent is controlled by outlet valve


58


. The outlet valve
