摘要:
An interlock structure for use with a pressure cooker is disclosed. The interlock prevents the pressurization of the vessel if the lid (28) is not securely attached to the pressure cooker body (30). The interlock also prevents the removal of the lid until the pressure within the vessel has dropped below a preset maximum.
