A non-pressurized, self-sealing coffee maker and a method for using the coffee maker with microwave energy is provided. The coffee maker is vented such that there is no danger associated with steam pressure. The coffee maker uses a vented siphon system which allows discontinuance of microwave energy after the siphon action has been initiated. The apparatus itself also includes a gravity transfer device which allows water to drip directly on the ground coffee and prevents scorching.

A microwavable coffee maker comprising: a receptacle unit for receiving brewed coffee and which has a vertical axis, a peripheral wall and at least one vent means in said peripheral wall; a filter unit for passing water through ground coffee which is coaxially mounted on top of the receptacle unit and which has a bottom wall having a filter means for supporting ground coffee and having an inclining wall portion having a surface that inclines toward the filter means for deflecting water onto and around the ground coffee and having a peripheral wall and at least one vent means in said peripheral wall; a reservoir unit for containing the water during heating which is coaxially mounted on top of the filter unit and which has a bottom wall, peripheral wall, at least one vent means in said peripheral wall, a siphon means and a passage means; the passage means adapted to extend through the bottom wall of said reservoir unit and having an outlet disposed directly above the filter means for transferring by gravity a first portion of water from said reservoir onto the ground coffee to prevent scorching of the ground coffee prior to transfer of a second portion of water through the siphon means; the siphon means being disposed inside the upper reservoir and adapted to extend through and be supported by the bottom wall of the reservoir and said siphon means having an outlet disposed directly above the inclining wall portion of the filter unit and the siphon means being adapted for transferring a second portion of the water from the upper reservoir unit by hydraulic head to the inclining wall portion of the filter unit; and a lid adapted for placement over the reservoir unit and adapted to allow the reservoir to be in communication with air outside the coffee maker by means of a vent hole in the lid and by means of a straight tube having a top opening facing above the lid and a bottom opening adapted to be disposed below the surface of the water at a selective depth before applying microwave energy and to be disposed above the surface of the water as water is transferred during the preparation process.
