Abstract
A horizontal hinged closure with a large diameter track ring attached directly to the rear of a female threaded head. The threaded female head is designed to removably attach to a male threaded structure. A bearing ring with cam followers that engage the track ring to allow the threaded head to be rotated relative to the male threaded structure to attach and remove the threaded head there from. The bearing ring is attached to a hinge arm that allows the removed threaded head to be moved away from the male threaded structure and then rotated about a vertical axis. Direct attachment of the large diameter track ring to the rear of the threaded head moves the center of gravity forward, resulting in the threaded head remaining essentially vertical when it is removed from the male threaded structure and thereby making it easier to reattach to the male threaded structure.
