Some food will overflow the pot when we cooking. It will cause hurt by hot vapor of we open the lid that time. There is a rubber part attached to the Non-overflowing Lid, which can be pushed down into a concave to show holes around it, letting out vapor when it is boiling. This can avoid overflow and hurt as well. The rubber part can be pulled up again when there is not so much vapor and the food needs to be well cocked. This simple structure helps us out from troubles and hurts, bringing more fun to cooking.
