A pressure vessel which is suitable for use as a cooking utensil, autoclave, or like device. The vessel includes a container with a number of pivotal, threaded shanks, and a lid with pairs of supports between which the shanks pass. Wing nuts on the shanks can be tightened to secure the lid to the container. The supports have upturned ends which, when the wing nuts are slackened to a limited extent prevent pivotal disengagement of the shanks from the supports. |
