ABSTRACT:
A pressure cooker with a safety device to prevent the lid from turning includes a lid handle and a cooking pan handle. The safety device is built-in to the lid handle, and includes a locking mechanism, a vertical sliding pushbutton that actuates a locking member, a residual pressure valve, and a cooker closed condition indicator rod. The pushbutton exerts pressure on a rocker, which moves the locking member horizontally over two opposing slope ramps in the surface of the locking member.
