Its actually magnetic rings. One ring molded into the cup, the other is a rubber magnet that is the stopper. When you push it onto the dispenser the rubber magnet lifts up and sticks to the dispenser, then when its full the magnet hits the bottom of the cup and makes a water tight seal. The magnet even has advertising or a team logo on it, and can be used as a fridge magnet when your done. These guys are gonna make a killing with this patent. The machine has a counter on it too, so no more free beers at the bar, .
