A K-Cup coffee maker is made by Keurig, and is known for making single-serving cups of coffee. The coffee maker makes coffee by funnelling water through a K-Cup and makes a cup of coffee that can be either 8, 10 or 12 ounces in size, depending on the user's choice.
The K-Cup coffee machine functions using Keurig’s patented K-Cup technology, which is basically a small plastic container that contains both ground coffee and a small filter with a foil lid. When the K-Cup is placed inside the machine, two sharp devices at the top and bottom of the K-Cup holder puncture both the foil lid of the cup and the plastic bottom below the filter. Once the holes are made, the hot water that has been heated by the machine is pressured through the K-Cup and into whatever cup or mug placed below.
The K-Cup technology was originally developed for brewing coffee, but has since been expanded for making tea, hot chocolate and even fruit drinks. In order to give users the best choice of coffee, Keurig has also licensed its technology to other coffee companies, including Green Mountain Coffee, Van Houtte, Caribou Coffee, Coffee People, Newman’s Own and many others.
