ABSTRACT:
A closure assembly10contains positive and/or vacuum pressure within a pressure vessel16having a neck12. A circumferential locking member22supported on a door20locks the door to the neck, and is radially moveable between an open position and a closed position. A seal26between the neck and the door maintains fluid-tight integrity. A lever or other hand powered operator may be used for moving the locking member between the open position and the closed position. The locking member may include locking segments interconnected to form the circumferential locking member.
