A kitchen without pressure cooker is like a human being without sole. Because nowadays it is not only the fashion but also it works with hand in hand with the working woman. This is because of saving in time & energy. It means that the pressure cooker has become an inevitable item in the kitchen. Easier handling will increase the life of the pressure cookers. From the ancient time, there were always innovations about cooking. The researchers always give advice over wastage of energy during cooking. Saving energy is always need of the nation and an approach for saving energy leads to the change in shape of a pressure cooker. These changes were in size of a pressure vessel, the shape of the lid or may be the provision of the coating to cooker. During the changes, alternative sources such as electrical and solar were also played an important role in energy saving. The shape of inner lid of pressure cooker used is elliptical in shape. This elliptical shape is for locking & easy to handle. The different alternatives for the shape of inner lid of pressure cooker were arising. But due to different restrictions, designers concentrated on changes in lid shape from circular to an ellipse. Also, the demerits of elliptical inner lid shapes are overcome by the hybrid shape of circular and elliptical i.e. circular shape having straight edges at the edges, as one of the alternatives. The modification suggested here is also serving the all purposes elliptical pressure cooker. The advantages obtained here are also giving better results for locking, increase in heat transfer area, reducing locking angle position in a measurable way and saving in waiting for time for food than the elliptical inner lid.
