         [0005]    To brew a decent cup of coffee or espresso using traditional methods not only requires a certain degree of skill, it is also often a lengthy and messy process. Conversely, recent advancements in cartridge-based single-serve coffee and espresso machine technology have made brewing these beverages quick, easy, and virtually mess-free. Because of this, approximately 20% of US households currently have a cartridge-based brewing system, and that figure has been growing annually. 
         [0006]    However, the exceptional convenience of these systems comes at a cost. First and foremost, a beverage brewed in a cartridge-based system costs 10-20 times more than the same beverage brewed using traditional methods. Secondly, there is a limited selection of coffee varieties available in cartridge form. Moreover, the amount of coffee in the cartridge is predetermined, so it always produces an average strength cup of average volume. 
         [0007]    Some brewing-machine models have attempted to fix this problem by allowing the user to select the volume, but even then you have no control over strength. In my experience, setting the volume to the highest setting over-extracts the grounds producing a watered-down bitter concoction, which forces me set the volume to the average setting and to use a second expensive cartridge for a larger beverage. 
         [0008]    There have been many attempts to resolve this shortcoming of cartridge-based brewing systems. One attempt is to create a re-useable cartridge that can be filled by the user with their selected beverage medium. An example of this type of device is described in US20020148358A1. In my experience, these re-useable cartridges are difficult to fill without spilling some of the beverage medium. Furthermore, they must be cleaned after each use, thereby undermining the convenience associated with the cartridge-based brewing system. 
         [0009]    Another attempt to resolve these issues is to create a partially or fully disposable cartridges that the consumer must fill and seal at home. Some examples include the Simple Cups™ and Fill &#39;n Brew™ systems. In my experience, using systems can be very time consuming and messy, again undermining the convenience associated with the cartridge-based brewing system. Furthermore, I have noticed that systems like these with disposable lids often leak out of the top, causing beverage medium (in my case coffee grounds) to end up in my beverage, which is quite unpleasant. This leak also seems to cause a lack of pressure inside the cartridge, as the beverage produced is very weak. 
         [0010]    The disclosed invention would allow for a consumer to have fully customizable coffee experience, all with the convenience of a cartridge-based brewing system. For example, in one embodiment, a consumer would simply approach a conveniently located (e.g. in a supermarket, mall, etc.) manufacturing and vending machine, enter their preferences into the user interface, insert their beverage medium (e.g. coffee grounds), and the machine would fill, seal, and dispense the cartridges automatically. One embodiment contains a beverage medium, allowing the consumer to purchase a beverage medium, fill, seal and receive customized cartridges all in one transaction. 
         [0011]    The disclosed invention thusly allows consumers full control over the type and amount of beverage medium in each cartridge. One embodiment even includes a grinder, to allow for an even fresher tasting beverage to be produced from the dispensed cartridges. Another embodiment includes a roaster and a grinder, to allow for even more control (e.g. coffee roast type) over the contents of their cartridge.

       Operation—FIG. 1 and FIG. 2 
       [0048]    As a consumer approaches a vending machine, the consumer observes the display monitor and the user interface. The user interface will make it clear to the consumer that they must have a beverage medium of appropriate fineness in order to proceed, unless the machine is equipped with a grinder. If the consumer has a suitable beverage medium, the consumer places their beverage medium on the scale and selects the type of container in which it is contained (e.g. paper bag, hard plastic container, metal container, etc.). The consumer then enters the appropriate commands at the user interface control system associated with the vending machine to select the quantity of cartridges to be dispensed and/or the type of beverage medium and/or the type of cartridge desired and/or the amount of beverage medium per cartridge. 
         [0049]    The user interface control system can employ simple menus and a fixed set of keys for the consumers to make their selections, it can employ break-resistant touch screens, or it can employ a combination of both. Once a selection has been made, the consumer would then merely commit to the purchase (receipt-based system), insert his/her magnetically encoded card into the card validator, or insert cash and/or coins into the bill validator and/or coin insert and, in response, the machine would prompt the consumer to pour the weighed beverage medium into the receptacle. Once the consumer is finished pouring, they will enter the appropriate command and the machine will manufacture and dispense the selected cartridges without the need for any further input by the consumer. 
         [0000]    Processing a Beverage Medium from an External Source— FIG. 3   
         [0050]    In the following three figures ( FIG. 3   a ,  FIG. 3   b , and  FIG. 3   c ), it is assumed that the consumer has obtained their beverage medium from an external source.

       a) The beverage medium is reweighed to correct for any consumer error, and either (i) the beverage medium is returned to the consumer through cartridge dispenser  42  (if the result of the second weighing close enough to the result of the first weighing) or (ii) the amount of beverage medium per cartridge is adjusted.   b) If the second weight obtained is within the tolerance, the beverage medium is sent through a grinding process which grinds the beverage medium to a fineness which is suitable for a particular cartridge-based brewing system. If equipment  44  is able to produce cartridges for more than one type of cartridge-based brewing systems, and those systems require different levels of fineness, the grinding process may adjust automatically to accommodate the required fineness level before grinding.   c) The beverage medium is packaged into cartridges in a suitable manner, and dispensed to the user through cartridge dispenser  42 .   d) Equipment  44  may or may not automatically clean itself for a suitably short amount of time. Cleaning may occur after every transaction is completed, after multiple transactions are completed, after a sensor is triggered, at another preset interval, or not at all.       
 
         [0060]    In one embodiment, shown as a diagram in  FIG. 3   c , the processes involved with cartridge manufacturing equipment  44  once the consumer has dumped their beverage medium into beverage medium receptacle  26  are as follows to make a cartridge. 
         [0061]    a) The beverage medium is reweighed to correct for any consumer error, and either (i) the beverage medium is returned to the consumer through cartridge dispenser  42  (if the result of the second weighing close enough to the result of the first weighing) or (ii) the amount of beverage medium per cartridge is adjusted.
       b) If the second weight obtained is within the tolerance, the beverage medium is sent through a roasting process (if roasting has been selected by the consumer).   c) The beverage medium is sent through a grinding process which grinds the beverage medium to a fineness which is suitable for a particular cartridge-based brewing system. If equipment  44  is able to produce cartridges for more than one type of cartridge-based brewing systems, and those systems require different levels of fineness, the grinding process may adjust automatically to accommodate the required fineness level before grinding.   d) The beverage medium is packaged into cartridges in a suitable manner, and dispensed to the user through cartridge dispenser  42 .   e) Equipment  44  may or may not automatically clean itself for a suitably short amount of time. Cleaning may occur after every transaction is completed, after multiple transactions are completed, after a sensor is triggered, at another preset interval, or not at all.
