Now a day’s having pressure cooker in kitchen is not only the fashion but also it becomes the important utensil of kitchen. Pressure cooker saves time & energy. From ancient time, researchers have been focusing on cooking. Their motto was to save thermal energy. The type of energy saving, may in electrical, solar etc. The save in energy may be direct or indirect. Some researchers gave various ways of direct energy saving & some were concentrated on indirect energy saving by change in design of pressure cooker. This change was in change in lid shape, size, material etc. The existing inner lid of pressure cooker is elliptical. The purpose of this shape is to lock & unlock the lid, ease of handling to working woman/man. The different alternatives for this shape were practiced. But due to manufacturing difficulties, designers concentrated on changes for lid shape of inner lid pressure cooker. The variations were started from circular to ellipse via various polygonal shapes. It is noted that elliptical shape has also some demerits. These demerits are overcome with hybrid lid having advantages of circular as well as elliptical lid. Formerly researchers followed different alternatives for the shape of lid; but this paper concentrate on modified lid i.e. circular shape having straight edges at periphery. This will be one of the best alternatives. This lid will also give better results in locking & increase in heat transfer area.
