According to the present invention, water is placed in a water reservoir constructed of plastic microwave-transparent, pressure-resistant material. A funnel positioned on the upper surface of filter compartment is supported on the upper edges of the water reservoir with the spout extending downwardly into the water reservoir. A lower filter is placed into the filter compartment, and coffee grounds or other espresso particulate substance is placed on upper surface of the lower filter. An upper filter is then positioned on the upper surface of filter compartment to restrain the coffee grounds or other particular substance during brewing. A filtrate reservoir is placed over the funnel, and twisted, thereby engaging threads to join the water reservoir and the filtrate reservoir. A filtrate splash cover is attached to the upper edges of the filtrate reservoir. The assembled espresso device is placed into a microwave oven. As water in the water reservoir begins to boil, steam is generated, and boiling water is displaced upwards through the funnel and grounds, forming espresso. The filtrate splash cover provides for both venting and fluid retention during brewing. A resilient gasket, in conjunction with a plurality of vent passages, provides an additional path for pressure relief. The espresso is automatically emptied into the filtrate reservoir, which is designed to function as a drinking cup for individually-sized portions.

[ What is claimed is:] [1.] A device for making beverages, comprising:A. a fluid reservoir having an exterior and a fluid-receiving interior, wherein said interior is enclosed by a wall having inner and outer surfaces, said fluid reservoir having at least first and second separable wall portions, said first wall portion having a first sealing surface and said second wall portion having a second sealing surface;B. a resilient seal having a first seal portion mating with said first sealing surface and a second seal portion mating with said second sealing surface for normally forming seals between the respective seal portions and sealing surfaces to seal said fluid-receiving interior, said first seal portion having an exterior portion exposed to pressure outside of said fluid reservoir and an interior portion spaced from said exterior portion;C. at least one vapor passage communicating between said fluid-receiving interior and said first seal portion between said interior portion and said exterior portion, said at least one vapor passage transmitting fluid pressure from said fluid-receiving interior to said first seal portion, said vapor passage and seal defining a pressure relief valve such that when pressure in the fluid-receiving interior of the fluid reservoir exceeds a predetermined level, the seal will deform to complete a passageway from the interior via at least one said vapor passage to the exterior of the fluid reservoir; andD. a compartment for retaining a beverage ingredient in contact with fluid from said fluid reservoir.
