Claims

[Claims for Utility Model Registration] (1) A leakage radio wave preventer for microwave ovens made of polymethylpentene mixed and dispersed with ferrite and/or metal powder, carbon, and a softener. (2) A leakage radio wave prevention device for a microwave oven as set forth in claim 1 of the utility model registration claim, which uses soft ferrite or hard ferrite as the ferrite. (3) A leakage radio wave preventer for a microwave oven according to claim 1 or 2 of the utility model registration claim, which uses pure metal powder and/or an oxide of pure metal powder as the metal powder. (4) Ferrite and polymethylpentene from 20 to
A leakage radio wave preventer for a microwave oven according to claim 1, 2, or 3 of the utility model registration claim, which utilizes a mixture of 85% by weight and 80 to 15% by weight. (5) The leakage radio wave preventer for a microwave oven according to claim 1, wherein the ratio of polymethylpentene to softener is 1 part by weight to 0.05 to 0.20 part by weight. (6) An annular sheet made of polymethylpentene that is attached to at least one of the rim of the opening of the microwave oven or the inner surface of the lid that comes into contact with the rim of the opening, the entirety of which is approximately the same shape as the rim of the opening; A leakage radio wave preventer for a microwave oven according to claim 1, which utilizes hard ferrite dispersed and mixed in one of the inner circumferential portion and the outer circumferential portion and soft ferrite in the other. (7) An annular sheet made of polymethylpentene that is attached to at least one of the rim of the opening of the microwave oven or the inner surface of the lid that comes into contact with the rim of the opening, and whose entire shape is approximately the same as the rim of the opening; A leakage radio wave preventer for a microwave oven as set forth in claim 1, which is comprised of a magnet embedded in a suitable position to magnetically attach the mouth edge of the main body and the lid. (8) A leakage radio wave preventer for a microwave oven according to claim 1, which is a plate provided with a large number of ventilation holes and is used as an interior material attached to the inner surface of the main body.
