Title: Beverage making device and a system for making a beverage

Description:
TECHNICAL FIELD 
     The present disclosure relates to a beverage making device, in particular but not limited to a beverage press device for making beverages. The present disclosure also relates to a system and method for making a beverage. 
     BACKGROUND 
     Coffee and tea are commonly made beverages. There are several commonly known devices and techniques of making coffee or tea using several devices. One technique of making these beverages involves brewing, in particular steeping ground coffee beans or tea leaves or ground tea leaves. Various beverage press devices can be used to brew beverages. Typically, beverage press devices include a container, a moveable plunger, and a filter. Water and other ground ingredients (e.g., ground coffee, tea leaves etc.) are mixed in the container and allowed to steep (i.e., brew) within the container. After a period of time of brewing (i.e., steeping), the plunger and filter are depressed toward the bottom of the container, through the mixed liquid to separate the particulates (i.e. ground ingredients) and the drinkable beverage. 
     The depressed plunger and filter keep contaminants (e.g., coffee grounds or tea leaves or other particulates etc.) away from the drinkable beverage that is above the filter. A common problem experienced by existing beverage press device users (e.g., French press users) is that the plunger may move upwards after it has been depressed due to natural resilience of the particulates (e.g., coffee grounds or tea leaves etc.) and/or due to pressure created in the liquid as the plunger is depressed. In turn, the contaminants may leak into or otherwise move into the drinkable beverage above, spoiling the taste of the beverage. 
     Another challenge when using beverage press devices (such as for example French press devices or Aero press devices etc.) is making beverages correctly. Users can often find it difficult to get the proportion of particulates (e.g., ground coffee beans or tea leaves etc.) and water. Further users can find it challenging to determine an appropriate brew time (i.e., time for particulates to steep within the water) to make a beverage.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     There are several commonly known devices and techniques of making coffee or tea using several devices. One technique of making these beverages involves brewing, in particular steeping ground coffee beans or tea leaves or ground tea leaves. Various beverage press devices can be used to brew beverages. A common problem is a plunger in beverage press devices is a plunger used to push the solids (e.g. ground coffee or tea leaves etc.) through the liquid can move away from a depressed position, thereby causing the solids to leak into the liquid. This can cause contamination or cause the liquid to become bad tasting or reduce time of steeping thereby reducing flavour. 
     The present invention relates to an improved beverage making device that can overcome one or more problems described earlier or provide the public with a useful alternative. The present invention relates beverage making device that comprises; a container that includes a base, a lid removably attached to the container and a plunger assembly. The plunger assembly comprises a filter, a first magnetic arrangement disposed on or within the plunger assembly, and the plunger assembly being moveable between a depressed position and an undepressed position. The beverage making device further comprises a second magnetic arrangement disposed on or within the container, wherein the first magnetic arrangement and the second magnetic arrangement retain the plunger assembly in the depressed position due to attraction forces between the first magnetic arrangement and the second magnetic arrangement. The retention of the plunger assembly in the depressed position helps to separate the particulates (i.e. solids such as ground coffee or tea leaves etc.) from the beverage in the container and prevents the particulates from contaminating the beverage made in the container. 
       FIG.  1    shows an example of a beverage making device  100 . The beverage making device  100  is a press type device. In one example the beverage making device  100  is an improved French press that may also be known as a cafetiere, cafetiere a piston, coffee press, coffee plunger or press pot or other such terms. The beverage making device  100  can be used to make coffee or tea or lemon water, fusion drinks, iced tea or other beverages where particulates (i.e. solids) are steeped within a liquid.

For example, the magnet chamber  226  may be screwed on to the base  202  or may be push fit or friction fit to the base  202 . Alternatively, the magnet chamber  226  is integrated into the container  200 . 
     The second magnetic arrangement  220  is disposed on an underside of the base  202  such that it is isolated from the contents of the chamber. This prevents the beverage in the chamber contacting the second magnetic arrangement  220  and spoiling the taste of the beverage. 
     The two magnets  222 ,  224  are disc shaped magnets and are spaced apart from each other in the magnet chamber  226 . In an alternative form, the second magnetic arrangement  220  may comprise one or more ferrous material sheet located within the magnet chamber  226 . In a further alternative form, the second magnetic arrangement may comprise a ferrous material sheet being attached to an underside of the base  202  or the base comprises a ferrous material. The ferrous material would be magnetically attracted to the magnets in the first magnetic arrangement  320 . 
     The magnets in the first magnetic arrangement are positioned and arranged to align with the magnets in the second magnetic arrangement. 
     In operation to make a beverage, particulates (e.g. ground coffee beans or tea leaves etc.) are added to the container, a liquid is poured into the container  200  and mixed together. The particulates are steeped in the liquid to brew a beverage. The plunger assembly  300  is then depressed. More specifically the plunger rod  310  is depressed such that the base plate  302  (cross plate), the filter  304  and the top plate  306  are moved through the container to filter out particulates (i.e. solids). The solids are collected as the plunger is depressed. The first magnetic arrangement  320  is attracted to the second magnetic arrangement  220  due to magnetic attraction between the magnets of opposite polarities. Alternatively, there is attraction between a magnet in a magnetic arrangement and ferrous material of the other magnetic arrangement. 
     The magnetic attraction retains the plunger assembly  300  in the depressed position. The magnetic attraction between the first magnetic arrangement  320  and the second magnetic arrangement  220 , pulls the base plate  302  in contact with the base  202  and retains the base plate  302  in contact with the base  202 . The plunger assembly  300  being retained in the depressed position separates the solids from the beverage above the top plate in the container. 
       FIGS.  6 A and  6 B  illustrate the attraction between first magnetic arrangement  320  and the second magnetic arrangement  220 .  FIG.  6 A  shows the base plate  302 , top plate  306  being brought close to the base  202  of the container. The magnetic attraction between the magnets  322 ,  324  of the first magnetic attraction and the magnets  222 ,  224  of the second magnetic arrangement causes the top plate  306  to be pulled into the recess and urges the base plate  302  toward the base  202  of the container. The final depressed position is shown in  FIG.  6 B . The magnetic attraction snaps the base plate and top plate into a depressed position and holds them in this depressed position. As shown in  FIG.  6 B  the spring  330  compresses as the top plate  306  is pulled into the recess  308 . The magnetic attraction between the first magnetic arrangement and the second magnetic arrangement retains the base plate  302  and top plate in a depressed position i.e. the plunger assembly is retained in the depressed position. The base plate  302  and the top plate  306  seal the contents below the base plate from the beverage above within the container. The seal is created by the sealing flange  314  against the inner surface of the container as seen in  FIG.  6 B . This seal prevents particulates under the base plate  302  from leaking into and contaminating the beverage. The magnetic arrangements are also advantageous because the beverage can be poured out of the beverage making device without requiring to hold down the plunger assembly. The plunger assembly is retained in the depressed position making pouring easier without contaminating the beverage. 
     The magnetic attraction retains the base plate  302  and top plate  306  in the depressed position, and prevents the top plate or base plate from moving away. The beverage making device is advantageous because the plunger assembly is retained in a depressed position due to the magnetic attraction between the first magnetic arrangement and second magnetic arrangement. This prevents the plunger assembly from moving out of the depressed position and reduces contamination of the prepared beverage by particulates escaping from below the plunger assembly. The strength of the magnets in the magnetic arrangements is sufficient to retain the plunger assembly in the depressed position, but this magnetic attraction can be overcome by a user pulling on the knob  312 . The plunger can be moved out of the depressed position by manually pulling on the knob  312 .

These components are implemented on PCBs with appropriate electronic components. 
     The system  400  is used to execute a method of making a beverage utilising the beverage making device  100  and the mobile communication device  410 . More specifically the mobile communication device executes the steps of: receiving a selection of a predetermined beverage recipe, determining, a ratio of liquid to particulates required to make the selected beverage; determining a required amount of solid and a required amount of liquid to make the selected beverage, determining, a required temperature of the liquid to make the selected beverage; determining a brewing time required to make the selected beverage, presenting the required amount of particulates, the required amount of liquid and the required temperature; receiving a mass of particulates added by a user from a sensor; receiving a mass of liquid added by a user from a sensor; presenting a timer that counts down or counts the determine brewing time; presenting a message to move a plunger assembly of a beverage making device to a depressed position within a container of the beverage making assembly, until a first magnetic arrangement associated with the plunger assembly is in proximity with a second magnetic arrangement located in a base of the container such that the plunger assembly is urged into and retained within the depressed position due to magnetic attraction between the first magnetic arrangement and second magnetic arrangement, such that when the plunger assembly is in a retained position the particulates are isolated from the prepared beverage within the container due to the plunger assembly being retained in the depressed position, and providing a message the selected beverage has been prepared. 
       FIGS.  8  to  12    illustrates screenshots presented on the mobile communication device  410  during a method of making beverage. The mobile communication device comprises a software application that is stored in its memory and executed by the processor  414 . The application when executed goes causes the mobile communication device  410  to execute a method of making a beverage. A particular beverage may be selected from a plurality of pre-stored recipes. 
     Referring to  FIG.  8   , the mobile communication device  410  can store multiple beverage recipes. The application automatically calculates a ratio of particulates and water for a selected beverage recipe. For example, for a particular coffee recipe the ratio of ground coffee to water is presented to the user on the graphical user interface (GUI)  418 . The various beverage recipes may be stored in memory. As seen in  FIG.  8   , a user is requested to input a cup size, the number of servings can be input, a coarseness of the ground and the required flavour are requested. The user can input these via graphical indicia or buttons or via the GUI. Once these parameters are received, the device  410  automatically calculates a ratio of coffee to water and an ideal temperature. This information is presented on the GUI  418 , as shown in  FIG.  8   . Favourite recipes can be stored by pressing the virtual “save recipe” button. Custom recipes may also be created. 
     Referring to  FIG.  9   , the mass of particulates added into the container  200  is measured by the load cell (or other weight sensor)  520 . The scale indicator  900  is filled to visually show a user the amount of particulates that are added to the container. Optionally an alarm, e.g. an audible and/or visual alarm, or any type of alert or message, may be raised, triggered or presented on the GUI  418  or another device if the mass of the particulates measured is greater than the required mass. In the illustrated example the particulates may be ground coffee beans. 
     Referring to  FIG.  10   , the amount of liquid (e.g. water) added to the container  200  is measured by the load cell  520 . The scale indicator  1000  is filled to visually show the amount of liquid added. An alarm may be raised and presented on the GUI if the mass of the liquid measured is greater than the required mass of liquid. The temperature of the contents of the container  200  are measured by the temperature sensor  510  and presented on the GUI. The real time temperature is presented in a temperature indicator  1010 . The temperature may be updated in real time or substantially real time based on information received at the mobile communication device  400  from the beverage making device  100 . 
     Referring to  FIG.  11   , a timer  1100  is presented on the GUI  418 . The timer may count to the requisite time. The requisite time may be pre-set based on the stored recipe. An alarm may be raised when the time has exceeded the requisite time. The temperature indicator  1010  may also be presented in conjunction to the timer  1100 . The timer relates to the amount of time the particulates (i.e. solids) are required to be steeped in the liquid to make the selected beverage. 
     Once the requisite time has been reached, a message is presented on the GUI  418 . The message indicates that the beverage needs to be plunged. As shown in  FIG.  12   , a message  1200  indicating that plunging is required is presented on the GUI  418 . The beverage making device is plunger assembly is depressed. The plunger assembly is retained in the depressed position due to magnetic attraction between the first magnetic arrangement and second magnetic arrangement. 
     The method of making a beverage and system for making a beverage is advantageous because the software application provides a step by step method of making beverage. The constituent ingredients amounts are calculated and presented, avoid guess work. The ingredients are measured thereby making the beverage more accurately. Furthermore, where chemical or electro-chemical sensors are used, nutrition or organic compounds such as fats, oils or caffeine, may also be detected and measured for the user. This provides improved taste and reduces approximations required by a user. The temperature is also measured in real time and therefore provides an improved beverage making process. The beverage making process helps to make a tastier beverage and provides a simplified step by step method for making beverages. 
     The method provides the parameters required to make a specific beverage. The described method is advantageous because it removes the guess work when trying to make the beverage. The method and system provides automated quantities and ratios of the ingredients to make a beverage. This again simplifies the beverage making process and allows for a more tasty beverage.
