ABSTRACT:
A somewhat resilient stopper seals the throat of a conventional glass coffee-maker flask and is provided with a pouring passage. The passage is valved by a horizontally swingable blade spring-biased toward its passage-closing position but movable to its passage-opening position by a timer-controlled mechanism. The timer can be set for different time periods by a manually movable member which can either be normally fixed to the timer or be easily removable so that it can be retained at the coffee-making station to insure against purpose-defeating resetting.
