A NOVEL PRESSURE COOKER WITH REINFORCED SHORT LIP AND A PROCESS OF MAKING THE SAME

摘要

A novel pressure cooker having a reinforced short lip with a protrusion length from the inner body wall is in between 10 to 13mm and having thickness greater than the thickness of the input raw material. The enhanced density and strength of lip is achieved by drawing the material from the body side of the pressure cooker and adding the material at the lip before the lip formation stage.
