Abstract
A lid for a pressure vessel comprising an inner skin having a seal groove formed in the periphery thereof by pressing, and a reinforcing member which is contiguous with at least a portion of the inner skin. In one embodiment, the reinforcing member comprises an L-shaped annular ring which backs up the seal groove region of the inner skin. In another embodiment the reinforcing member completely covers the inner skin. In this embodiment the central section of the inner and outer skins are part spherical and are contiguous with one another. An air gap exists radially inwardly of the seal groove between the two skins. In another embodiment the inner and outer skins are spaced apart over their central section and on insulating may be disposed in the space so formed.
