Casserole cover for kitchen utensil e.g. pan, has thin sheet fixed on non-disposable framework by folding outer edge on framework, where sheet resists specific temperature and has less thickness

摘要

The cover has a non-disposable framework (1) with indentations in its central zone to reduce surface and weight of the framework. A thin sheet (3) is fixed on the framework by folding its outer edge (4) on the framework and resists a temperature of the order of 120 degree Celsius. The thin sheet is made of aluminum foil with a thickness between 30 and 80 microns or of poly-tetra fluroethylene.
