PROBLEM TO BE SOLVED: To obtain a percolating coffee maker. SOLUTION: This coffee maker is provided with a reversely conical cup 4 having a through-hole in a center, a lock board 5 having water stop parts 3 is fitted to the center of its base part, the water stop parts 3 are lowered by water pressure so as to tightly block the through-hole 43 of the cup 4 in addition to the lowering of the lock board 5 by its weight and coffee is steamed inside the cup. Since the lock board 5 is made to be provided with a proper sized diameter, the lock board 5 is elevated upward when the cup 4 is placed on a container with a different sized diameter so as to automatically separate the water stop parts from the through-hole 43 and percolated coffee is automatically poured into the container. |
