Abstract: A disposable coffee pot includes a lower section containing water which is heated by an external heat source. Pre-packaged ground coffee beans are located above and isolated from the water until the temperature of the water is elevated. When the bottom of the coffee pot is heated by a heat source, the water is allowed to boil increasing the pressure in the lower section causing that boiling water to rise out of the lower section. The heat applied to the coffee pot also ruptures a partition wall separating the water from the coffee beans, to allow the hot water to contact the beans and form a coffee extract. The coffee is extracted and then accumulated in an upper section through a pipe so that it is possible to collect and drink the coffee from the upper section.

Abstract: A disposable coffee pot includes a lower section containing water which is heated by an external heat source. Pre-packaged ground coffee beans are located in either the lower section or in a central section isolated from the water until the temperature of the water is elevated. When the bottom of the coffee pot is heated by a heat source, the water is allowed to boil increasing the pressure in the lower section causing that boiling water to rise out of the lower section. The hot water also ruptures a container for the ground coffee beans, or a valve separating the water from the coffee beans, to allow the hot water to contact the beans and form a coffee extract. The coffee is extracted and then accumulated in an upper section through a pipe so that it is possible to collect and drink the coffee from the upper section.
