- Not Applicable
- The dispenser disclosed herein relates to an automated single cup coffee dispenser.
- Today's coffee consumer desires both affordability and customization. Coffee shops offer the desired customization, but are expensive. Conversely, many home and office coffee makers can produce a pot of coffee relatively inexpensively, but offer no customization to each cup. This has led to single cup automated coffee dispensers for use in home and at the workplace. The typical version of these machines use small plastic cups which contain the ground coffee beans. There are certain deficiencies in current models of single cup automated coffee machines. For example, there are millions of plastic cups that re discarded everyday and fill up our landfills, and thus are not eco friendly.
- Accordingly, there is a need in the art for an improved coffee dispenser.
- Referring now to the drawings, a coffee dispenser for preparing coffee by mixing a liquid coffee extract and hot water is disclosed. The coffee dispenser may dispense a single serving of coffee. The coffee dispenser may have one or more ports for receiving one or more containers each having liquid coffee extract, flavoring and a creamer. These ports are in fluid communication with a mixing chamber or blending chamber which receives a single serving of liquid coffee extract and hot water as well as other flavors (e.g., flavors or creamers) desired by the consumer. The mixing chamber outputs the mixed ingredients to an outlet port valve into a cup below. One benefit of such a design is the elimination of single serving cups of coffee grounds, and the plastic waste associated with their use. The use of a coffee extract eliminates the need for a single serving cup of coffee grounds. A container of liquid coffee extract may contain from 10 to 300 servings, depending on the selected serving size. However, it is also contemplated that the container of liquid coffee extract may contain between 1 to 300 services. Further, by utilizing the liquid coffee extract, certain benefits may be achieved including but not limited to weight loss. Further, the chlorogenic acids in coffee extract can reduce blood pressure. For example, 140 mg of green coffee bean extract per day may reduce blood pressure. Finally, antioxidants found in coffee, which reduce free radicals in the body may reduce general cell damage and stress. Antioxidants, using the same process, may also reduce the proliferation of four kinds of cancer cells. Green coffee may be useful in preventing some types of cancer. Other coffee extracts may provide similar or additional benefits. By way of example and not limitation, these other extracts may include coffee bean extract, banana extracts, almond flavor extract, butter extract, cinnamon extract, coconut extract, hazelnut extract, maple extract, anise extract, lemon extract, lime extract, mint extract, orange extract, peppermint extract, raspberry extract, root beer extract, rum extract, strawberry extract or combinations thereof.

coffee dispenser 10 for preparing coffee by mixing a liquid coffee extract and hot water is disclosed. Thecoffee dispenser 10 may dispense a single serving of coffee. Thecoffee dispenser 10 may have one or more ports for receiving a container having liquid coffee extract, flavoring and a creamer. These ports may be in fluid communication with a mixing chamber or blending chamber 88 (seeFIGS. 4 and 5 ) which may receive a single serving of liquid coffee extract and hot water. The mixingchamber 88 may also optionally receive other flavors desired by the consumer. The mixingchamber 88 outputs the mixed ingredients to an outlet port valve 92 (seeFIG. 5 ) into acup 12 below. One benefit of such a design is the elimination of single serving cups used to store and deliver coffee grounds to consumers, and the plastic waste associated with their use. A container of liquid coffee extract may contain from 50 to 300 servings, depending on the selected serving size. Although the preferred embodiment utilizes a large container that can hold multiple servings, it is also contemplated that the container may store and deliver a single serving of coffee extract. In this regard, the container of liquid coffee extract may contain between 1 to 300 servings depending on the selected serving size. Further, by utilizing the liquid coffee extract, certain benefits may be achieved including but not limited to weight loss. Further, the chlorogenic acids in coffee extract can reduce blood pressure. by way of example and not limitation, 140 mg of green coffee bean extract per day may reduce blood pressure. Finally, antioxidants found in coffee, which reduce free radicals in the body may reduce general cell damage and stress. Antioxidants, using the same process, may also reduce the proliferation of four kinds of cancer cells. Green coffee may be useful in preventing some types of cancer. Other coffee extracts may provide similar or additional benefits. - Referring now to
FIG. 1 , acoffee dispenser 10, for dispensing a single serving ofcoffee 12 is shown. Thecoffee dispenser 10 may include ahousing 14 with anupper portion 16 and alower portion 18. Thelower portion 18 may be supported by abase 20 and may be defined by anarcuate wall 22 which supports theupper portion 16. Theupper portion 16 may have aflat side 24 that rests on top of thearcuate wall 22. Two controls, aserving size selector 26 and afroth level control 28 may be located on anexterior surface 30 of theupper portion 16 of thehousing 14. Awater reservoir 68 may surround thelower portion 18 and rests on thebase 20. - As shown, the
cup size selector 26 may be defined by arotatable knob 32 and two or morecup size icons 34. InFIG. 1 , threecup size icons 34 are shown for small, medium and large. The knob includes anindicator 36, which points to thecup size icon 34 that is currently selected by the servingsize selector 26. Instead of arotatable knob 32, the servingsize selector 26 may be a three button system, with one button for each of the cup sizes. Alternatively, the serving size selector may be integrated in to a touch panel control. In a further alternative, the serving size selector may be a toggle control in combination with an indicator or display. By way of example and not limitation, there may be three LED lights, one for each of the possible size selections. Also, instead of LED lights, a display may be provided which shows the selected cup size, either via a number or an icon, as a user toggles through the possible cup sizes. - The
froth level control 28 may be control by ahorizontal slider 38. Thehorizontal slider 38 may move from afirst end 39 of the slider's range of motion to a second end 40 of the slider's range of motion. The first end may correspond to a minimal amount of froth, and the second end may correspond to a maximum amount of froth or vice versa. The slider may be positioned at any number of positions between the two ends. - The
upper portion 16 may have three ports. Acoffee concentrate port 42 may also be disposed on theupper portion 16. Thecoffee concentrate port 42 may have a larger circumference than the other two ports in order to accommodate a correspondingly sizedcoffee concentrate container 44. Aflavor concentrate port 46 may be disposed on a left side of thecoffee concentrate port 42. Theflavor concentrate port 46 may accept a correspondingly sizedflavor concentrate container 48. On a right side of theupper portion 16, acream concentrate port 50 may be disposed. Thecream concentrate port 50 may accept a correspondingly sizedcream concentrate container 52. Although theport 42 have been described as having a different size compared to 46, 50, it is also contemplated that theports 42, 46, 50 may be all the same size, or each of theports 42, 46, 50 may be a different size from each other. Each of the containers may contain a liquid concentrate. The coffee concentrate may be an extract of a coffee bean. The cream concentrate may be a de-hydrated dairy product, and the flavor concentrate may be a liquid formulated to impart the flavor of a specified coffee beverage, such as cappuccino, mocha, espresso, or other flavors. As shown inports FIG. 2 , the 42, 46, 50 may use a threaded connection. However, other attachment methods are also contemplated. By way of example and not limitation, theports 42, 46, 50 may use a friction connection or a twist and lock connection, or a detent connection. Theports 42, 46, 50 may be located in other areas on the upper portion on elsewhere on theports coffee dispenser 10. The ports and the containers that hold the liquid flavors (i.e. coffee extract, flavor, creamer) may be disposed above the mixingchamber 88 so that the liquid may flow into the mixingchamber 88 by way of gravity. Other means of flowing the liquid flavors into the mixingchamber 88 are also contemplated including but not limited to providing a pump that actively forces the liquid flavor into the mixing chamber. In this case, the courts and the containers that holds the liquid flavors may be disposed below the mixingchamber 88. - As shown in
FIG. 2 , the ports may further include a 53, 54, 55. Each of thevalve coffee port valve 53,flavor port valve 54, andcream port valve 55 may include aconnection portion 58, aspike 60, and avalve portion 62. Theconnection portion 58 may have a thread, corresponding with athread 94 on thecoffee concentrate container 44,flavor concentrate container 48, and cream concentratecontainer 52. Thevalve portion 62 may include a spring-biasedvalve 64, and a sealingelement 66. The spring-biasedvalve 64 may be biased closed by and may seal against the sealingelement 66. The sealingelement 66 may be made of rubber or another elastomeric compound. The springbiased valve 64 may return to its original position once displaced. Thevalve 64 allows fluid to flow through thevalve 64 when displaced. It is also contemplated that the valve may be, for example, a ball valve, or a butterfly valve, or a needle valve, or any other valve that offers the required control while allowing sufficient flow. Thevalve 64 may be displaced either through an actuator controlled by the computer or by manually pressing the container downward. By way of example and not limitation, the user may press any one of the 44, 48, 52 once for a single serving of liquid contained in thecontainers 44, 48, 52. If additional servings of the liquid are desired, the user may depress any one of thecontainers 44, 48, 52 additional times.containers - The
water reservoir 68 may surround thelower portion 18 of thehousing 14. A bottom of the water reservoir may also rest on thebase 20. Thewater reservoir 68 may be generally U-shaped along its horizontal cross section. Thewater reservoir 68 may have an open top. The open top of the U-shape may be sufficiently wide to allow the water reservoir to surround thehousing 14 on three sides. Thewater reservoir 68 may be fabricated from a transparent material in order to allow a user to observe the water level therein, and alid 70, which is shown as being opaque. Removal of thelid 70 allows a user to fill thewater reservoir 68 with water. Thewater reservoir 68 interfaces with the base 20 at anintake 72 formed in the top of thebase 20, and located at a position on the base near the center-bottom of thewater reservoir 68. Thelid 70 may fits under theflavor concentrate port 46 and thecream concentrate port 50 as the ports extend outward from theupper portion 16 of thehousing 14. This configuration gives additional stability to thewater reservoir 68 by preventing vertical movement of thewater reservoir 68 once thewater reservoir 68 is installed in thecoffee dispenser 10. - It is contemplated that the
water reservoir 68 may be merely translucent, or may be opaque and have a transparent window to allow a user to gauge the water level in the container. Thelid 70 may be translucent or transparent to allow a user to more easily gauge the water level. Thelid 70 may havesides 74 which extend over the correspondingsides 76 of thewater reservoir 68 at anopen end 78 of thewater reservoir 68. Thelid 70 may include a sealing strip (not shown), made from rubber or a similar elastomer, which is located on an interior surface of thesides 74 of thelid 70, and extends inwardly to seal against the sides of thewater reservoir 68. It is also contemplated that thesides 74 of thelid 70 extend in to an interior of thewater reservoir 68 and include the sealing strip for sealing on an exterior surface of thesides 74 of thelid 70. In this configuration, the sealing strip extends outwardly, and seals against an interior surface of thesides 76 of the container 69 near the open end. - The operating systems, including the operating internal components of the
coffee dispenser 10, are shown schematically inFIGS. 4 and 5 . The primary difference between the schematics provided inFIGS. 4 and 5 is that thedispenser 10 shown inFIG. 4 dispenses the concentrate manually, whereas thedispenser 10 a shown inFIG. 5 dispenses the concentrate via a computer controlled valve. - The
froth level control 28 and servingsize selector 26 may be connected to thecomputer 84 via a wired 96 or wireless connection. Thewater reservoir 68 may be connected, through theintake 72, to apump 82 via tubing or piping 56. Thepump 82 may be electrically connected, either wired 96 or wirelessly, to thecomputer 84, which allows thecomputer 84 to turn thepump 82 on and off. Thepump 82 may be connected to aboil chamber 86 via piping ortubing 56. The boil chamber is a heater for heating water. Theboil chamber 86 may be connected to a mixingchamber 88 with piping ortubing 56. The boil chamber may be in communication with a computer either with awire 96 or wirelessly. Thecomputer 84 may turn theboil chamber 86 on and off in coordination with thepump 82. Based on the froth level control setting, the computer may set the temperature to which the boil chamber will heat the water therein. Thus, thewater reservoir 68, pump 82 andheater 86 are connected in line to the mixingchamber 88, and theboil chamber 86 and pump 82 have individual electronic connections to thecomputer 84. The boil chamber is computer controlled but may be controlled through other non computerized means including but not limited to an electronic circuit. - The flavor concentrate
42, 46, 50 may be connected to the mixingports chamber 88 with 53, 54, 55 placed in between to control the flow of concentrate. Thevalves flavor concentrate port 46 may be directly connected to the mixingchamber 88 or the flavor concentrate port may be connected to the mixing chamber via tubing or piping 56. As discussed above, avalve 54 may be disposed between theflavor concentrate port 46 and the mixing chamber. The flavor port valve may be operated manually or electrically connected to thecomputer 84 for operation. Thecoffee concentrate port 42 may be directly connected to the mixing chamber or the flavor concentrate port may be connected to the mixing chamber via tubing or piping. Acoffee port valve 53 may be disposed between the coffee concentrate port and the mixing chamber. The coffee port valve may be operated manually or electrically connected to the computer for operation. Thecream concentrate port 50 may be directly connected to the mixing chamber or the flavor concentrate port may be connected to the mixing chamber via tubing or piping. Acream port valve 55 may be disposed between the cream concentrate port and the mixing chamber. The cream port valve may be operated manually or electrically connected to the computer for operation. - In operation, a user may select the amount of froth desired in the serving of
coffee 12 using thefroth level control 28, and set the desired serving size using theserving size selector 26. In the embodiment shown inFIG. 4 , the user may also operate the 53, 54, 55 by pressing on the corresponding concentrate container in order to move the container toward the corresponding valve. As the user applies enough force, the bias in the valve is overcome, and the valve operates to allow concentrate through the valve. Each press of the concentrate container operates the valve to allow a predetermined quantity of flavor concentrate, coffee concentrate, and cream concentrate to enter the mixing or blendvalves chamber 88, where they come into contact, mixing to some degree. The 44, 48, 52 and corresponding valves are sized and shaped such that one press on the concentrate container corresponds with a small serving size set by the serving size selector. Two presses on either of the concentrate containers with introduce a predetermined quantity of concentrate to the mixing chamber corresponding to a medium serving of coffee. Three presses on either of the concentrate containers with introduce a predetermined quantity of concentrate to the mixing chamber corresponding to a large serving of coffee. However, each concentrate container may be pressed as many times as desired by a user to reach the user's desired flavor combination.concentrate containers - In the embodiment shown in
FIG. 5 , to begin the automated portion of the process of making a serving of coffee, the user presses the activation button orcontrol 90. The activation button may be a push button function built in to the serving sizeselector rotatable knob 32. Alternatively, the activation button may be a separate button or non-latching switch. Once the activation control is operated by the user, thecomputer 84 may operate thepump 82 to draw water from thewater reservoir 68 in to and through theboil chamber 86, which heats the water to a temperature determined by the froth level control and communicated to the boil chamber by the computer. The boil chamber may heat water to a temperature of 100 to 210 degrees Fahrenheit. Preferably, the boiler chamber heats water to a boiling temperature of 190° F. to 210° F. The boil chamber may steam water and send it to the mixing chamber at a temperature of 210 degrees Fahrenheit or more. Thus, the water that is introduced into the mixingchamber 88 may be at a temperature of about 100 degrees Fahrenheit to 210 degrees Fahrenheit in order to bring out the flavor of the liquid coffee extract. At temperatures of 190 degrees or more water will boil, and at 210 degrees or more, will change states to steam. As the water boils or changes phase from water to steam, the boil water or steam creates increasing degrees of froth, according to the froth setting selecting by the user via the froth level control, as described above. - After the
boil chamber 86 heats the water, thepump 82 then moves the water to the mixingchamber 88. The mixing chamber may be shaped as an inverted truncated pyramid in order to facilitate, via the force of gravity, the movement of the serving of coffee in the mixing chamber to an outlet port valve. The inverted truncated pyramid configuration is shown schematicallyFIG. 4 . However, the inverted truncated pyramid configuration may also be incorporated into the mixingchamber 88 shown inFIG. 5 . After mixing, the outlet port valve at a bottom of the mixing chamber opens to allow the coffee to flow out of the mixing chamber and in to a cup below. The outlet port valve, may be, for example, a spring loaded pressure valve, or any other type of pressure valve which would open the valve when the proper pressure inside the mixing chamber is reached. The outlet port valve may also include acooling element 100 which operates to cool liquid passing through the outlet port valve if the liquid is above a certain temperature such as 190 degrees Fahrenheit. The cooling element ensures that the liquid passing out of the outlet port valve is at or below the predetermined temperature. For example, the cooling element may ensure that the liquid passing out of the open valve between 170° F. and 190° F. if the heater or boiling chamber raises the liquid to a temperature that is too high (e.g. above 190° F.). - The embodiment shown in
FIG. 5 operates in a very similar manner to the embodiment shown inFIG. 4 except for how the concentrate is added to the mixingchamber 88. In particular, thecomputer 84 is connected toflavor port valve 54,coffee port valve 53, andcream port valve 55. After operation of thefroth level control 28 and servingsize selector 26, and subsequent operation of theactivation button 90 by a user, the computer using the selected serving size, operates the 53, 54, 55 to add a corresponding pre-determined amount of each type of concentrate based on a size indicated by the servingvalves size selector 26. The remainder of the operation is the same as that described for the embodiment ofFIG. 4 , above. - Although the embodiment shown in the figures illustrates a dispenser that can dispense more than one serving, it is contemplated that the dispenser can be configured to be a single serve dispenser with or without a container 69. If no container is used, then the water for the coffee will be inserted into a container having an open top that is filled each time the user wants to make a single serving of coffee.
- The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including various ways of configuring the stand. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein. Thus, the scope of the claims is not to be limited by the illustrated embodiments.
