Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent a lid from being blown up high and thereby, ensure safety in cooking by arranging a penetration rod which penetrates into the yellow and white of an egg stored in an open vessel, on the lid. SOLUTION: The yellow and white W of an egg without a shell, of a single piece of an uncooked egg stored in an open vessel 1, are perforated with a tooth pick in such a manner that such a perforation takes place at a few spots on the surface. Then a lid 2 is fitted into the open vessel 1, and the open vessel 1 with the lid 2 on is placed in a microwave oven. The soft boiled yellow and white of the egg is ready after heating for a specified time. If the yellow and white W of the egg are not perforated, or the number of tiny holes is small, or the boiling time is a little longer, the penetration rod 3 serves to open tiny holes in the yellow and white W of the egg, when the lid 2 with the rod 3 is fitted into the open vessel 1 and the rod 3 penetrates into the yellow and white W stored in the open vessel 1. At the same time, the soft boiled yellow and white W of the egg stick to the penetration rod 3, so that the lid 2 is prevented from being blown up high, and instead, is, at the best, allowed to be open. Thus the safety in cooking is ensured.
