ABSTRACT:
A top assembly for substantially sealing the open mouth of a coffee pot to thereby prevent oxidation and evaporation of the coffee. The top assembly includes a single passageway for both introducing coffee into the pot and for pouring coffee from the pot. The passageway includes a plurality of substantially parallel sub passages. The sub passages form a liquid trap which prevents air from entering the passageway as well as preventing evaporation from the pot. The sub passages are interconnected to form a channel which is substantially U-shaped in cross-section. The inlet to the liquid trap from inside the coffee pot is at the base of the U-shaped channel so that when the coffee pot is tilted to pour coffee from the pot, there is a gravity flow through the liquid trap and the liquid head pressure insures that all coffee in the pot may be poured out.
