A Coffee Pot That Stops Brewing when the Pot is Removed

This automatic coffee pot is equipped with a “pause and serve” feature. The lid of the pot presses up on the button (shown below), releasing a valve that allows the coffee to pour into the pot.

If you remove the pot before brewing is finished, the valve closes so coffee is not spilled. (A friend who owns one of these reports that the valve leaks like a sieve. A good try nonetheless.)
