Description

BEVERAGE DISPENSER

FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to a beverage dispenser and, more particularly, but not exclusively, to a beverage dispenser for hot and cold beverages including multiple flavors.

Beverage dispensers are well known in the art.

European Patent No. 1831097 by Guerrero et al. teaches a beverage dispenser and method for preparing hot and cold beverages by mixing one or more additives with a base liquid. Geurrero teaches varying the proportion of the additives in order to improve mixing as the base liquid is dispensed.

International Publication WO 2011/163227 by Metropulos et al. teaches a beverage dispenser for mixing and dispensing liquids. The beverage dispenser has a mounting bracket with a carrier that is removably connected to the mounting bracket and a mixing bowl that is removably connected to the carrier. The beverage container also has a first set of fittings extending from the mounting bracket for receiving a first set of liquids and dispensing the first set of liquids into the mixing bowl. The beverage container also has a second set of fittings also extending from the mounting bracket for receiving a second set of liquids and dispensing the second set of liquids into the mixing bowl.

International Publication WO 2011/163233 by Metropulos describes a method and system for managing the dispensing of beverages from an automatic beverage dispensing unit. The beverages may be comprised of a single or multiple ingredients, including a first plurality of liquids, a second plurality of liquids, and/or a combination of one or more first and second plurality of liquids. The beverages are dispensed according to a pouring schema. The pouring schema may be a beverage recipe and may be preprogrammed by a system manager, or alternatively, be chosen by a consumer during operation of the system.

International Publication WO 03/091152 by Carhuff et al. describes a fluid or beverage dispensing device having self-cleaning dispensing nozzle. The device includes a body provided with a conduit having a first end to which a dispensing nozzle is connected, and a second end to which a fluid inlet line is intended to be connected. The device further includes a collector member that can move relative to the body between a first dispensing position in which the outlet of the nozzle is released from the collector member and a second cleaning position in which the collector member is placed in front of the nozzle outlet to collect any fluid that exits the outlet.

The present invention, in some embodiments thereof, further relates to a spout for a bag-in-box and, more particularly, but not exclusively, to a kit for aseptically dispensing contents from the bag-in-box.

Many systems dispense liquids or semi-solids from a disposable package consisting of a flexible collapsible bag in a box. Such a package is commonly referred to as a bag-in-box (BiB) dispensing package. Generally, these systems include a bag that is provided with a spout through which dispensing occurs. The BiB is typically purchased from a filling facility that receives the bag from a manufacturer as an empty pre-made bag, fills it with the desired content and packs it into a box. The pre-made typically includes a single spout and cap that is closed and sterilized. The filling process typically includes decontaminating the outer exposed area of the cap and spout, and then removing the cap, filling the bag through the spout and replacing the cap, all within a sterilized environment. In some known BiBs, the cap is installed with a tube through which contents of the bag can be dispensed. In such cases the tube is required to be relatively short so as to avoid obstructing the aseptic filling. Other known BiBs include two spouts, one with a simple standard cap for filling the bag and another that is used for dispensing.

The BiB has many common commercial applications. One exemplary common application is to supply syrup to a drink dispensing system, e.g. a soft drink fountain. Typically, drink dispensing systems include a plurality of BiBs each of which supply syrup to a fountain via a dedicated tube or hose connected between the BiB and valve in the fountain. Typically, the hose is reusable and is connected to the spout of the BiB on site of the fountain drink system. In such an application, the aseptic quality of the bag and its contents is lost as soon as the cap of the bag is opened for connecting the hose to the spout on the bag. Similarly, for a BiB that includes a manual tap, the aseptic quality of the bag and its contents is lost as soon as the tap is used to dispense the contents.

U.S. Patent No. 4,498,508 entitled "Container Filler," the contents of which is incorporated herein by reference, discloses a device for filing a container through a spout extending from the container. The device includes a sterile chamber having a wall opening therethrough for inserting the spout into the chamber. A cover inside the chamber is positioned over a base plate which encloses the wall opening to prevent the escape of sterile gas from the chamber when the spout is being inserted into and removed from the wall opening. A pair of jaws fit around the spout when the spout is in the wall opening to hold the spout in position for filling and to prevent contamination of the sterile chamber during the filling operation.

Japanese Patent Application No. JP2002160766, entitled "Bag for bag in box, bag in box, and bag for liquid," the contents of which is incorporated herein by references describes a method for solving the problem that an elastic tube obstructs aseptic filling. It is described that a bag for a bag in a box includes a liquid inlet on one side surface of the bag, and an outlet tube at a heat welded portion therearound. The liquid outlet tube is welded by heat to be sideways extended from the bag.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

An aspect of some embodiments of the invention relates to a beverage dispenser comprising a plurality of beverage components, wherein the beverage dispenser may be divided into a door and body and wherein at least one of the beverage components is positioned in the door and at least one of the beverage components is positioned in the body. In some embodiments, "beverage components" refers to containers including a beverage component. A container may be a bag in box or other container known in the art, for example water in a heating unit or ice bank. In some embodiments, the door of the beverage dispenser is movable between an open and closed state, wherein in the open state containers positioned in the body and door are accessible to a user while in the closed state of the door, containers positioned in door and body are not accessible to a user. In some embodiments, the door is divided into two or more parts, wherein each part is separately openable and closable.

In some embodiments of the invention, a depth of the door is between about 20- 60% of a depth of the body of the dispenser, for example about 50% thereof. In some embodiments, the weight of the door is between about 40-80% less than the weight of the body, for example between about 40-60% less, in order for the body not to fall over when the door is opened, and optionally leaned upon.

In some embodiments, beverage components include one or more diluent and one or more additives. Optionally, the diluent(s) are positioned in the body of the dispenser and one or more of the additives are positioned in the door of the dispenser. Optionally, one or more additives are also positioned in the body of the dispenser. For example, in some embodiments, water is positioned in the body of the dispenser and one or more flavors, acids and artificial sweeteners are positioned in the door of the dispenser. Optionally, sugar is positioned in the body of the dispenser.

In some embodiments, one or more of the beverage components are in liquid form. Optionally, all beverage components are in liquid form.

In some embodiments, beverage components stored in small containers are positioned in the door while beverage components stored in larger containers are positioned in the body. For example, a diluent may be positioned in the body of the dispenser whereas flavors or acids may be positioned in the door of the dispenser. Optionally, sugar is also positioned in the body of the dispenser. In some embodiments, containers weighing between 0-3kg are positioned in the door of the dispenser, for example, flavor containers weighing about 2kg may be positioned in the body of the dispenser. Optionally, containers weighing between 3- 10kg are not positioned in the door of the dispenser and may be positioned in the body of the dispenser, for example a container of sugar liquid weighing about 8kg may be positioned in the body of the dispenser. Optionally, heavier beverage components may be provided in the body of the dispenser, for example a water tank weighing between 20-50kg may be stored in the body of the dispenser.

In some embodiments, the dispenser further includes elements for processing beverage components. For example, the beverage dispenser may include one or more of a heating unit for heating liquids, a cooling unit, such as an ice bank for cooling liquids, a grinder for grinding coffee beans and a coffee brewer for extracting coffee from coffee grounds. In some embodiments, beverage components which are processed in the dispenser before dispensing are positioned in the body of the dispenser. For example, coffee beans or grounds or hot liquids may be positioned in the body of the dispenser.

In some embodiments of the invention, a cooling unit is provided for chilling beverage components positioned in door and body of the dispenser. In some embodiments, a cooling unit is provided in one of the body and door of the dispenser and cooling agent (gas or liquid) is transferred from the body of the dispenser to the door of the dispenser for chilling beverage components, or vice versa. Optionally, the cooling unit can be used to chill beverage components located both in the body and in the door at the same time. Chilling can reduce the temperature of the beverage components any desired temperature lower than the temperature in the machine, for example to between 1-25 degrees Celsius and more particular to between 18-20 degrees Celsius.

In some embodiments, tubes and nozzles connected to containers with beverage components are positioned along with the beverage components. For example, tubes and nozzles attached to beverage components positioned in the door of the dispenser are also positioned in the door of the dispenser. Optionally, pumps for dispensing beverage components are also positioned along with the beverage components, either in the body or door of the beverage dispenser.

An aspect of some embodiments of the invention relates to a pouring unit which can be separated into a body pouring unit and a door pouring unit. In some embodiments, the door and body pouring units are separated when opening a door of the dispenser and are united when closing the door of the dispenser on the body of the dispenser. In some embodiments, the door pouring unit includes nozzles attached to beverage components stored in the door of the dispenser whereas the body pouring unit includes nozzles attached to beverage components stored in the body of the dispenser. In some embodiments, when opening the door of the dispenser, no tubes are hanging in between the door and body of the dispenser.

In some embodiments, beverages are prepared by mixing beverage components dispensed from the door pouring unit with beverage components dispensed from the body pouring unit. Optionally, two or more beverage components are simultaneously dispensed.

In some embodiments, beverage components dispensed from the door pouring unit impinge on a stream formed by one or more beverage components dispensed from the body pouring unit. Optionally, the components impinge before reaching a beverage container in which the beverage is dispensed.

In some embodiments, adjusting or alignment elements are provided for ensuring accurate connection between door pouring unit and body pouring unit when the door of the dispenser is closed and the pouring units are united. For example, the alignment elements may ensure accurate direction of the nozzles so that components dispensed from the door pouring unit will impinge upon a stream dispensed from the body pouring unit, optionally at a desired angle. Optionally, the alignment elements are spring elements or the like. In some embodiments, one or more alignment elements are provided on the door pouring unit.

In some embodiments, one or more holders may be provided in the door of the dispenser for hanging tubes connected to the door pouring unit, optionally such that no tubes are hanging in between the door and body of the dispenser when the door is opened.

Optionally, one or more of the nozzles are fixed to the pouring unit and can be removed by unscrewing screws or the like. Alternatively or additionally, one or more of the nozzles are positioned in holders in the pouring unit and are easily removable. For example, nozzles can be positioned in suitable holes in the pouring unit and be removed by pulling the nozzle away from the hole. In some embodiments, all nozzles in the door pouring unit are removably positioned in the door pouring unit and no screws or the like are required for removing nozzles from the door pouring unit. Optionally, some of the nozzles are disposable and replaceable. Optionally some of the nozzles are interchangeable. For example, nozzles in the door pouring unit can be interchanged. Alternatively, some or all of the nozzles have specified positions in the pouring unit and cannot be interchanged.

An aspect of some embodiments of the invention relates to methods of mixing beverage components. Optionally, the beverage components are dispensed from a pouring unit as described herein. Alternatively, the beverage components are dispensed from other pouring units and nozzles known in the art.

In some embodiments, the beverage components include one or more diluents and one or more additives which are mixed together to form a beverage. A dispensing process starts with dispensing of a first component and ends when all components are dispensed in accordance with some embodiments of the invention. Optionally, some of the components are dispensed simultaneously. In some embodiments, diluent is dispensed along the entire dispensing process.

In some embodiments, the additives are dispensed towards the end of the dispensing process such that dispensing of the last additive ends the dispensing process.

The inventors of the present application have found that dispensing of the additives at the end of the process causes less foam to be formed in the container as opposed to dispensing of additives at the begin of or during the entire dispensing process.

In some embodiments, no full overlap of additive dispensing is provided, such that each additive either ends before or starts after dispensing of other additives. Accordingly, the starting point of additive dispensing depends on the number of additives dispensed and is calculated to ensure that dispense of the last additive will end the dispensing process. In other embodiments, one or more additives may be dispensed simultaneously, optionally with full overlap between the additives.

Additives optionally include one or more of flavors, acids, artificial sweeteners, nutritional additives and combinations thereof. In some embodiments, dispensing of flavors starts before dispensing of acids. Optionally, dispensing of acids starts before an artificial sweetener, if dispensed.

In some embodiments, a sweetener, such as liquid sugar, is dispensed during the entire dispense process and is not included in the additives defined above. Alternatively, dispensing of sweetener starts before and/or ends after dispensing of additives. The inventors have found that distributing dispensing of a sweetener along the entire or most of the dispensing process provides better mixing of the components. In some embodiments, sugar is dispensed along between 50%- 100% of the dispensing process such as between 60%-80% or about 70% of the dispensing process. Optionally, sugar is dispensed towards the end of the dispensing process and the dispensing process starts by dispensing of diluent only.

An aspect of some embodiments of the invention refers to impinging or mixing of beverage components after being dispensed from a beverage dispenser.

In some embodiments, one or more additives impinge on a diluent stream at a same impinging point along the diluent stream. In some embodiments, sugar impinges on the diluent stream at a point further downstream of the impinging point of the additives. The sweetener is thereby added to the diluent stream after all or most other additives are added. The inventors of the present application have found that adding sweetener (sugar) to the stream after other additives are added provides better mixing of the beverage components as opposed to adding sugar before or at the same impinging point as the additives. In addition, since the sweetener stream is often strong the diluent stream may move at the point of impingement of the sweetener stream on the diluent stream. Therefore providing a different impinging point for the sweetener stream may prevent deviation of impinging point between the additive streams and diluent.

An aspect of some embodiments of the invention refers to a milk nozzle for a beverage dispenser. In some embodiments, the milk nozzle is provided in a body pouring unit or a door pouring unit as described above. In other embodiments, the milk nozzle is provided in any pouring unit known in the art.

In some embodiments, a milk nozzle is movable between a dispensing position and a cleaning position, wherein in the dispensing position the milk nozzle is positioned above a beverage container (or shelf for beverage container) and in the cleaning position the milk nozzle is positioned above drainage or other internal container. In some embodiments, the milk nozzle is moved to the dispensing position only when milk is to be dispensed and is positioned in the cleaning position when no milk is dispensed. Keeping the milk nozzle in the cleaning position when no milk is dispensed prevents undesired dripping of milk from the milk nozzle into beverage containers. In some embodiments, a method for dispensing milk is provided, wherein the method includes moving the milk nozzle from a cleaning position to a dispensing position, dispensing milk and returning the milk nozzle to the cleaning position. Optionally, the milk nozzle is returned to the cleaning position immediately after dispensing milk by the nozzle. For example, the milk nozzle is returned to the cleaning position within less than 5sec, and more specifically within less than 1 second after dispensing milk by the nozzle.

In some embodiments, a tube for steam is attached to the milk nozzle for providing frothed milk.

In some embodiments, a milk tube connects between the milk nozzle and a milk container. Optionally, the milk tube is also connected to a hot water supply thereby enabling hot water to flow through the milk tube and milk nozzle and clean the milk tube and nozzle. Alternatively or additionally, the milk container may be replaced by a cleaning solution in order to clean the milk tube and nozzle. Optionally, cleaning is performed when the milk tube is in the cleaning position thereby flowing the hot water and/or cleaning solution into drainage.

In some embodiments, more than two positions are provided for a milk nozzle, for example the milk nozzle may include a cleaning position for cleaning the nozzle, a dispensing position for dispensing milk from the milk nozzle and a resting position when not used.

In some embodiments the milk nozzle may be used for other beverage components.

An aspect of some embodiments of the invention refers to a user interface for ordering beverages from a beverage dispenser. Optionally, the user interface is provided on a control panel, such as a touch screen, on a beverage dispenser. Alternatively or additionally, the user interface is provided as a mobile application or web page.

In some embodiments the user interface enables a user to select between different options for a beverage. In some embodiments, after a selection by the user additional options are displayed and the previous selection of the user is optionally highlighted. The options for a beverage may include one or more of, combination of the requested drink with additional flavors, type of sweetener, sweetening level and size of drink according to some embodiments of the invention. Optionally, information on the beverage is provided upon selection of the user. For example, nutritional information about the chosen beverage can be provided. Optionally, calories of the chosen drink may be presented, so as to enable a consumer to order a drink with the desired amount of calories or sugar. This may be especially useful for consumers on a diet or diabetic consumers. In addition, allergenic information may be presented for allergic consumers.

In some embodiments, a user may insert desired nutritional contents of the beverage and a suggested beverage is displayed. For example, a desired amount of calories, and optionally also a level of sweetness, may be inserted by a user, upon which a suggested amount of sugar and/or combination of sugar and artificial sweetener is suggested and displayed.

In some embodiments, the user may choose between a number of provided options, each represented by a separate icon, by touching/pressing the desired icon. Optionally, some of the options are provided as a dynamic animation and the user may choose between the options by moving one or more icons on the screen or other animation. In some embodiments, a user may choose amount of drink by filling a cup or jar to a desired amount or by indicating a number of consumers for the beverage by moving icons.

In some embodiments, a chart may be provided for indicating a ratio between two beverage components, such as sugar/artificial sweetener, flavor/sweetener or flavor/caffeine. A ratio between the components can be indicated by movement of an icon along an axis. Optionally, the axis represents a ratio between two beverage options, for example two ends of the axis may represent hot/cold and movement along the axis may indicate a desired temperature.

Optionally, the chart includes two axes (e.g. X and Y axes) for further indicating a level of beverage component or flavor. For example, a sweetener chart may comprise an X axis for indicating a ratio between sugar and artificial sweetener and a Y axis for indicating level of sweetness of the beverage. By moving a spoon or other icon on the chart, the amount and type of sweetener may be indicated. Optionally, the icon changes when moved along the chart. For example, the color of the icon may change to indicate the level of flavor/sweetness. Optionally, nutritional information displayed on the icon, or at another location on the screen, changes when the icon moves along the chart. For example, a number of calories or caffeine level may be displayed as the icon is moved along the chart.

In some embodiments, the user may select between about or more than 10, 100 or 1000 or infinite options when using a dynamic animation.

The user interface screens optionally also include animations for directions of use or for entertainment of the user. Optionally, animations are adjusted according to a selected beverage, season of the year and/or for specific markets. Optionally, advertisements are also provided on the screens.

An aspect of some embodiments of the invention relates to dynamic recipes for beverages. In some embodiments, recipes are stored in a memory either in the dispenser or remote from the dispenser. In some embodiments, recipes for one or more beverages may change according to beverage options chosen by a user. Optionally, selection of an amount of a first beverage component by a user affects an amount of a second beverage component in the beverage. For example, the amount of sugar in a beverage may affect the amount of acid dispensed for the same beverage.

In some embodiments one or more recipes for beverages include functions defining a relationship between two or more beverage components. For example, a beverage recipe may include a function for sugar relative to acid such that the amount of acid in a beverage is calculated according to the user's selection for amount of sugar.

An aspect of some embodiments of the invention relates to calibration of non- stepper motors. Optionally, the non-stepper motors activate pumps connected to beverage components, such as additives or sweetener.

In some embodiments, the pumps are provided in a beverage dispenser as described herein. Alternatively, the non-stepper motors are provided in other dispensers or apparatuses known in the art. Optionally, the non-stepper motors are regular DC motors as known in the art.

In some embodiments, calibration of non-stepper motor consists of initial calibration of a motor before use and ongoing calibration of the motor during use of the motor.

In some embodiments, an index for a motor is defined, optionally by a manufacturer of the motor or of the dispenser. Optionally a full or partial rotation is indicated as an index. In some embodiments, time between indexes of a motor is measured before intended use of the motor. In some embodiments, time between indexes is measured at different operation speeds of the motor and updated in an index table.

In some embodiments the measured time is used as a reference for controlling operation of the motor.

According to some embodiments of the invention, time between indexes is also measured during operation of the motor for activating a pump and the index table is updated accordingly. Optionally, time between indexes is measured during each operation of the motor. Alternatively, time between indexes is measured at some operations of the motor.

An aspect of some embodiments of the invention refers to power management of a beverage dispenser in order to keep the total power consumption below a capacity of the input power source or in order to save battery power. Optionally, the input power source is a standard power socket. In some embodiments, a dispenser includes a plurality of power consuming elements, for example a heater, a steamer, a cooling compressor, a grinder, pumps, controllers and more.

In some embodiments, power consuming elements of the dispenser are controlled according to power consuming rules in order to keep the total power consumption below a capacity of the input power source. Optionally, one or more of the rules define a number of power consuming elements that may not operate simultaneously. For example, a rule may define that a heater and a steamer may not operate simultaneously. Optionally, one or more of the rules define operation time or standby time of power consuming elements. Optionally, one or more of the rules define priority of power consuming elements. For example, in order for the rules not to interfere with ordinary use of the beverage dispenser, a rule defines that a heater will be prioritized to operate when hot drinks are ordered from the dispenser.

An aspect of some embodiments of the invention relates to a spout for a bag-in- box and, more particularly, but not exclusively, to a kit for aseptically dispensing contents from the bag-in-box.

The present inventor has found that while a BiB is installed in a dispensing system, e.g. a drink dispensing system, it contents become contaminated and/or altered over time due to exposure with the outside environment. Exposure, for example in a drink dispensing system, begins as soon as the cap of the bag in the BiB is opened for connecting the spout to the hose through which the content is dispensed. For systems in which the contents of the bag is typically dispensed over extended period of time, e.g. over weeks or months, the risk of damage to contents of the bag can be significant.

The present inventor has found that contamination of the contents of the bag can be prevented by pre-assembling an aseptic hose sealed on the bag and connecting the hose to a peristaltic pump prior to breaking a seal at a free end of the hose. The peristaltic pump provides for isolating the contents left in the bag from the outside environment and maintaining the aseptic quality of the bag and its contents.

Some known BiBs include a short aseptic hose, e.g. of up to 10 cm that is pre- assembled on a cap of the bag. The present inventor has found that this known solution for aseptically connecting a hose to the bag would not be suitable for a dispensing system that requires a longer tube, e.g. of between 30-300 cm or more.

During filling of the bag, the cap is required to be introduced into the filling apparatus, e.g. for sterilization, removal of the cap for filling of the bag and reinsertion of the cap when filling is completed. The present inventor has found that a long tube could potentially get caught and/or damaged in the filling apparatus and that the long tube can also potentially prevent proper sealing during sterilization and thereby compromise the sterility of the process. The addition of the long tube can also affect the needed volume of a sterilization chamber of the filling apparatus. In addition, a tube that is introduced into a sterilization chamber would have to be resistant to heat and/or chemicals used for sterilization. Such a requirement would typically be associated with increased costs.

Other known BiBs include an aseptic hose that is heat welded on a portion of a bag that is displaced from the spout through which the bag is filled. This solution although suitable may be associated with higher cost and more leakage problems. Yet another known BiBs include two sets of spout and cap at different positioning on the Bag- one cap for filling and one for dispensing. This solution although suitable may be associated with higher cost and increased volume needed to be packed in the box. The added volume can be a significant disadvantage for smaller bags where the volume added by the additional spout is relatively high compared to the total volume of the bag and its parts. According to some embodiments of the present invention, there is provided a spout for a BiB that can be used for aseptically filling the bag and also for maintaining the aseptic quality of the contents of the bag during dispensing. According to some embodiments of the present invention, the spout includes a dedicated outlet port and/or nozzle positioned on a portion of the spout that is not to be enclosed within a sterilization chamber of a filling apparatus during filling of the bag. According to some embodiments of the present invention an aseptic tube is connected to the outlet port on one end and aseptically sealed on the opposite end. Typically, the tube is connected to the output port in a bag manufacturing site so that the bag with tube is sterilized. The present inventors have found that by positioning the outlet port and the connected tube on a portion of the spout that is not to be enclosed within a sterilization chamber, any length tube can be aseptically connected to the bag. In addition, there is no need to sterilize the tube during filling. The BiB with spout as described herein may be used with known filling apparatuses. Typically, contents of the bag does not penetrate through the outlet port and/or tube during filling since the tube is sealed on its free end and the outlet port is typically significantly smaller than the spout used for filling. As such, the air is locked in the tube and prevents entry of content from the bag during filling.

According to some embodiments of the present invention, the outlet port is integral to the collar and is shaped as a nozzle extending out from a collar of the spout. According to some embodiments of the present invention, the outlet port is bored through a collar and/or wall of the spout and a tube fitting and/or nozzle for connecting a tube is introduced into the bore. According to some embodiments of the present invention, a bag is retrofitted with an adaptor and/or sleeve that is an extension of the spout and includes the dedicated outlet port as described herein from which an aseptic tube is connected.

According to some embodiments of the present invention, a BiB kit includes a bag fitted with a spout or spout adaptor including a dedicated outlet port as described herein, a cap for sealing the spout, and a tube that is sealed on one end. Optionally, the kit includes a nozzle and/or tube fitting that can be fitted into the outlet port of the spout or spout adaptor. Optionally the nozzle is integral to the spout or adaptor, e.g. extending out of a collar of the spout or adaptor. Typically, the tube fitting, nozzle and/or outlet port is sized to connect to the tube. Typically, the kit is fully assembled and then sterilized by Gamma radiation. The present inventor has found that by providing a dedicated output port on the spout of a bag, contamination of contents of the bag can be prevented without incurring large costs and/or without significantly increasing the volume of the BiB kit. The dedicated output port can be formed as part of the spout and/or retrofitted on an existing spout at relatively low costs. Moreover, the tube pre- assembled on the bag is typically a single use tube. Optionally, lower grade tubing can be used since the tubing is not required to be heat or chemical resistant as for tubes that require sterilization by heat or chemicals. Optionally, the diameter of the outlet port can range from 0.1 mm - 15 mm depending on parameters of the tube, parameters of the spout and parameters of the contents of the bag. Other sizes for outlet ports can be used as required. Typically, the outlet port has a smaller diameter than that of the spout. Typically, the diameter of the spout is in a range of 1-5 cm, although other spout sizes can be used.

For example, in some embodiments, a sweetener and sweetener nozzle may be provided in the door unit instead of or in addition to the sweetener in the body unit as described above. In some embodiments, no coffee and/or milk nozzle are provided. In some embodiments, one or more of the additives may be stored in the body instead of in the door as described. In some embodiments, additives may be stored in the door of the dispenser and connected to a nozzle in a body pouring unit of the dispenser or vice versa. Reference is now made to dispensing of beverage components through pouring unit 500 or other pouring units known in the art, in accordance with some embodiments of the invention.

FIGs. 5D and 5E illustrate different views of central pouring unit 500 when fluid is dispensed from nozzles in the unit in accordance with some embodiments of the invention.

FIG. 5D illustrates dispensing of milk 542 from milk nozzle 536 and coffee 544 from nozzle 526 into a container 560. In some embodiments, milk 542 and coffee 544 do not mix before entering into container 560. Optionally, sugar is also dispensed from nozzle 534 and/or one or more additives, such as artificial sweetener, are dispensed from one of nozzles 514. Optionally the sugar and additives do not mix with the coffee and milk before reaching container 560. Streaming of milk, coffee and diluent may occur simultaneously or consecutively in accordance with embodiments of the invention.

FIG. 5E illustrates dispensing of a cold or hot beverage into a container 560 in accordance with some embodiments of the invention. A diluent 552 is dispensed through diluent nozzle 522, optionally in a straight linear path. One or more additives 554 are optionally dispensed through nozzles 514 and mix with the diluent stream at an impinging or mixing point 555. Optionally, all components dispensed from nozzles 514 impinge on the diluent stream at the same point. Optionally, impinging point 555 is at between about 10°-75°, for example between 15°-55° of diluent 552.

A sweetener, such as sugar, 556 is optionally also dispensed through nozzle 534. Sweetener 556 hits the stream at an impinging mixing point 557 which is optionally located further downstream of impinging point 555. In some embodiments, impinging point 557 is at a same or similar angle to stream 552 as impinging point 555 of the additives. In these embodiments, nozzle 534 is positioned at a distance from nozzles 514, or lower than nozzles 514, to obtain a further downstream impinging point 557 for the sweetener.

In some embodiments, when dispensing cold or hot beverages all beverage components impinge on the diluent stream before the stream reaches the container.

In some embodiments, mixing of the components occurs in the dispensing stream and before reaching the container. Optionally, mixing is continued in the container by turbulence of the stream. In other embodiments, a mixing chamber (not shown) is provided for mixing all or some of the components before reaching the container.

Post-mixing of the components as taught, i.e. mixing of the components after they exit the dispenser, is advantageous since fewer parts of the dispenser get contaminated during use as opposed to pre-mixing devices, where the components are mixed in the dispenser. Post-dispenser mixing thus reduces cleaning requirements of dispenser parts. However, post dispenser mixing of the components may produce undesired foam in the container. In addition, it has been found that pre-mixing of the components usually provides better mixing of the components as opposed to post mixing. The present invention, in some embodiments thereof, provides a solution to the problem of undesired foam and/or a solution to obtain good mixing of the components.

FIGs. 9 A and 9B are diagrams showing methods of dispensing of different beverage components in accordance with some embodiments of the invention. The methods may be used by controller 180 with embodiments of the dispenser described above or with any other beverage dispenser known in the art. In some embodiments, the methods may be provided as source program, executable program, scripts or other form on computer implemented medium.

FIG. 9A illustrates an impinging or mixing point of various beverage component streams with a diluent stream 910. In some embodiments, the diluent is water. Optionally, the water is heated or chilled. Optionally, a combination of diluents forms a diluent stream. For example, hot and cold water may be dispensed simultaneously to obtain a beverage at ambient temperature. Optionally, the water is carbonated.

One or more additives 922 are optionally added to the diluent stream and impinge on the stream at point 912. Additives 922 may include, but are not limited to, flavors, acids, artificial sweeteners, nutritional additives, or combinations thereof.

Sweetener 924 may be added to diluent stream 910 at point 914. Sweetener 924 optionally comprises liquid sugar, for example at between 40-75Bx or at about 65Bx sugar-to-water ratio. Sweetener 924 preferably impinges on the diluent stream at a different point than additives 922. Impinging point 914 of sweetener 924 is preferably positioned further downstream of impinging point 912 of additives 922. Sweetener 924 is thereby added to the stream after all or most other additives are added. The inventors of the present application have found that adding sweetener to the stream after other additives are added provides better mixing of the beverage components. In addition, since the sweetener stream is often strong the diluent stream may move at the point of impingement of the sweetener stream on the diluent stream. Therefore providing a different impinging point of the sweetener stream may prevent deviation of impinging point between the additive streams and diluent.

In some embodiments, a distance between impinging points 912 and 914 can is between 2-20mm, or at least 2mm. optionally, a distance between impinging point 914 and a beverage container (not shown in FIG. 9A) is between 10- 100mm. optionally, when the diluent is carbonated water, the distance between impinging point and a beverage container is as short as possible in order to restrict loss of carbonation of the diluent during dispense. For example, the distance between impinging point 914 and a beverage container may be between 10- 15mm.

FIG. 9B is a time chart of the dispense process of FIG. 9A in accordance with some embodiments of the invention. Diluent 910 is optionally dispensed during the entire dispense process. Additives 922 are dispensed towards the end of the dispensing process, optionally such that dispensing of the last additive ends with the dispensing process. In some embodiments dispensing of the last additive ends between 10-500msec before or after ending dispensing of the diluent. Optionally, dispensing of the last additive ends before or after 1-3 seconds ending dispensing of the diluent. The inventors of the present application have found that dispensing of the additives at the end of the process causes less foam to be formed in the container.

In some embodiments, no full overlap of additive dispensing are provided, such that each additive either ends before or starts after dispensing of other additives. Accordingly, the starting point of additive dispensing depends on the number of additives dispensed. As shown in FIG. 9B, four separate additives are dispensed. The time of dispensing of the first additive is calculated such that dispensing of the other three additives will finish before the end of the diluent dispense. In other embodiments, one or more additives may be dispensed simultaneously, optionally with full overlap between the additives.

The order of dispensing of additives is optionally determined with respect to the characteristics of the dispensed additives in order to obtain minimal foam during dispense. In some embodiments, dispensing of flavors starts before dispensing of acids. Optionally, dispensing of acids starts before an artificial sweetener, if dispensed.

A sweetener, such as liquid sugar, is optionally also dispensed during the entire dispense process. Alternatively, dispensing of sweetener starts before and/or ends after dispensing of additives. The inventors have found that distributing dispensing of sweetener along the entire or most of the dispensing process provides better mixing of the components.

In some embodiments, dispensing of a beverage takes between about 4-12 seconds. Optionally, dispensing of an additive takes between 0.05-3 seconds.

As described above, in some embodiments, timing of the beverage components is important. For example, according to the dispense process shown in FIG. 9B, start and end time of dispensing of additives should be accurate. In addition, the amount of beverage component to be dispensed is fixed and any change can affect taste the dispensed beverage.

According to some embodiments of the invention, pumps of beverage components are activated by stepper motors which provide accurate operation and control of amount and timing of dispense. However, stepper motors are generally expensive and substantially raise the costs of the beverage dispenser. Accordingly, some embodiments of the invention use regular DC motors for activating pumps of beverage components, such as additives or sweetener. An aspect of some embodiments of the invention refers to calibration of DC motors to accurately control dispense amount and time of beverage components.

An index for a motor is defined, by a manufacturer of the motor or of the dispenser. Optionally a full or partial rotation of the motor is indicated as an index. According to the calibration method of some embodiments of the invention the time for a motor to run between indexes is accurately measured and used as a reference for controlling the operation time of the motor. Since the time between indexes can change, for example due to wear of DC motors, according to some embodiments of the invention time between indexes is measured during each operation of the motor. The calibration methods are described below with respect to a dispenser described herein. These calibration methods are suitable for calibration of any DC motor with the necessary changes. FIG. 10A is a flowchart of an exemplary calibration process according to some embodiments of the invention. At 1002 motor speed is adjusted. Motor speed is generally measured according to PWM, where 100% PWM is the maximum speed for the motor. The motor is then run and time between two indexes is measured. A table is then updated with the speed of the motor and time between indexes. FIG. 10B illustrates an exemplary table 1050 used for calibration of a DC motor according to some embodiments of the invention. 1002, 1004 and 1006 are repeated for different speeds of the motor until table 1050 is filled.

At 1008 a beverage component is dispensed by activation of the motor. During dispense, time between indexes is measured, at 1010. If the resulting index time is different than the time in table 1050, table 1050 is updated with the updated time. Optionally, table 1050 is updated with an average between last runs of the motor. Optionally, when the resulting time is substantially offset from the time on the table, e.g. more than 15%, the table is not updated and additional runs are first measured. Optionally, after a number of measurements exceeding 15% offset, the table is updated with the new measurements.

FIG. 12A is a schematic diagram 1200 of software modules of beverage dispenser 100 according to some embodiments of the invention.

A pair of grippers and/or jaws 31 is shaped to fit around spout 13 of a container 11, e.g. a bag for BiB kit.

During a filling operation, container 11 is brought near bottom plate 23 of sterile chamber 21 while cover 51 is positioned over opening 27. Spout 13 is inserted through the opening 27 while a pair of jaws 31 is slightly opened. Jaws 31 close and hold spout 13 in place and seal sterile chamber 21 from the outside environment. A sterilizing fluid, from source 54 sterilizes the volume under cover 51 and also sterilizes the exterior of spout 13 and cap 15. After spout 13 and cap 15 have been sterilized, cover 51 is moved away from spout 13 and cap 15. Cap 15 of the container 11 is removed from spout 13 by a well-known cap removing apparatus (not shown). Sterile chamber 21 is then moved upward, until nozzle 73 enters the spout 13 of the container 11. The product contained in filling tube 71 is then dispensed through nozzle 73 and spout 13, and into container 11. Once container 11 has been filled, sterile chamber 21 is lowered again to its initial position and cap 15 is again placed on spout 13 to seal container 11. Cover 51 is positioned over opening 27 and spout 13. Because the cover 51 is in place over opening 27 when the jaws 31 are opened, essentially no contamination from outside enters sterile chamber 21. After jaws 31 are opened, spout 13 is removed and filling apparatus 10 is then ready to receive another container 11.

It is noted that the invention is not limited to being practiced with the filling apparatus shown in FIG. 14. The invention may be practiced with other filling apparatuses, e.g. other filling apparatuses known in the art.
