An universal gas permeable, vapor releasing cover for adapting cooking vessels for use in a microwave oven includes a patterned array of openings to permit venting of vapors and gases in a relatively flat microwave permeable cover designed to accommodate varying sized vessels of the general shape described by the lid. A set of such covers can serve all popular shapes of such vessels. The holes may be tapered to reduce clogging.

A universal microwave-permeable safety lid for use with an open top microwave heating vessel comprising: a substantially planar microwave permeable member which when placed on the open top of a microwave heating vessel forms a barrier except for a plurality of relatively small gas and vapor permeable openings therethrough which allow the vessel to retain an amount of heated vapors and gases within the lid at ambient pressure and to provide for the venting of vapors and gases, above ambient pressure; wherein the lid is in a shape describing a corresponding vessel geometry and the openings are in a pattern which distributes the venting over the cover area; wherein the lid is of a size large enough to accommodate a plurality of sizes of open vessels substantially of the geometry described by the lid, the opening pattern further being configured to accommodate the distributive venting of vessels of several sizes; the lid being further provided with at least one integral handle configured to extend beyond the side-wall of the vessel; and wherein the plurality of openings are configured in the shape of back-to-back frusto-conical sections, such that they are easily cleansed, the minimum diameter occurring central to the thickness of the lid.
