Abstract A microwave cooker capable of cooking an assortment of foods by a variety of methods while maintaining constant pressure. The cooker of the present invention boils and steams foods continuously without pressure build up and without the need to shut off the microwave oven. Food spattering and spillage are prevented by a unique internal baffle rib design and a mechanism that releaseably locks the top cover.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
284 words
A microwave cooker comprising: a cooking container member adapted to hold food to be cooked, said container having at least one sidewall defining an open top; an inner lid member adapted to be inserted into the open top of said container member for closing the container member open top, said inner lid member having at least one upwardly extending baffle rib inwardly spaced from the perimeter of said inner lid member, said inner lid member having at least one vent hole for permitting steam to escape from the container during cooking and a peripheral edge; formations on at least one of said members for supporting said inner lid member in position within said container member adjacent said open top; a top cover adapted to overlie and cover said inner lid member and to define with said inner lid member a space therebetween for the accumulation of steam and boiling-over food, said top cover having a downwardly dished central portion and at least one downwardly depending baffle rib spaced inwardly from the outer edges of said top cover and having at least one vent hole in said central portion, said top cover rib being in a spaced relationship to said inner lid baffle rib, and said top cover vent hole being laterally spaced from said inner lid member vent hole when said top cover is positioned in overlying relationship with said inner lid member; and a means for releasably locking said top cover to said cooking container member, whereby said inner lid member and said top cover will remain in place during cooking and effluent steam will have a tortuous path between said vent holes in said inner lid member and in said top cover.
Claim 2
Dependent Claim
284 words
A microwave cooker comprising: a cooking container member adapted to hold food to be cooked, said container having at least one sidewall defining an open top; an inner lid member adapted to be inserted into the open top of said container member for closing the container member open top, said inner lid member having at least one upwardly extending baffle rib inwardly spaced from the perimeter of said inner lid member, said inner lid member having at least one vent hole for permitting steam to escape from the container during cooking and a peripheral edge; formations on at least one of said members for supporting said inner lid member in position within said container member adjacent said open top; a top cover adapted to overlie and cover said inner lid member and to define with said inner lid member a space therebetween for the accumulation of steam and boiling-over food, said top cover having a downwardly dished central portion and at least one downwardly depending baffle rib spaced inwardly from the outer edges of said top cover and having at least one vent hole in said central portion, said top cover rib being in a spaced relationship to said inner lid baffle rib, and said top cover vent hole being laterally spaced from said inner lid member vent hole when said top cover is positioned in overlying relationship with said inner lid member; and a means for releasably locking said top cover to said cooking container member, whereby said inner lid member and said top cover will remain in place during cooking and effluent steam will have a tortuous path between said vent holes in said inner lid member and in said top cover.
