Abstract
Abstract A protective cover for a dish being heated in a microwave oven is formed of moisture-absorbent, microwave transparent material forming a top member and an encircling wall member depending downwardly from the periphery of the top member to completely cover the dish to protect the interior of the oven from any possible spattering of food particles during the heating. The cover is formed of absorbent material so that any escaping fluids and food particles may be captured or absorbed by the cover. The wall member is fluted to give the cover self-supporting rigidity, and an upper edge of each fluted portion coincides with a scalloped portion of the top member. The cover may be treated with a microwave safe resin to increase the rigidity of the cover.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A shroud to cover a dish in a microwave oven, the shroud formed of moisture-absorbent, microwave-transparent paper, and comprising: a top member having at least one vent hole to permit the escape of steam during heating of food in the dish, and a plurality of scallops around the edge of the top member, and a wall member depending downwardly from the periphery of the top member, the wall member having a plurality of fluted portions with an upper edge of each fluted portion coinciding with a scallop, and the fluted portions positioned in a manner to strengthen the wall member sufficiently that the wall member is self-supporting.
Claim 2
Dependent Claim
107 words
A shroud to cover a dish in a microwave oven, the shroud formed of moisture-absorbent, microwave-transparent paper, and comprising: a top member having at least one vent hole to permit the escape of steam during heating of food in the dish, and a plurality of scallops around the edge of the top member, and a wall member depending downwardly from the periphery of the top member, the wall member having a plurality of fluted portions with an upper edge of each fluted portion coinciding with a scallop, and the fluted portions positioned in a manner to strengthen the wall member sufficiently that the wall member is self-supporting.
