Abstract
A pressure-type containment device with an improved lid sealing feature is disclosed. A lid disk seats on a shoulder along the interior wall of a container mouth and is held in place by a fastening ring adapted to fit into the container mouth. A resilient gasket, such as an O-ring, is wedged between the fastening ring and the lid disk along the interior wall of the mouth. The margin of the fastening ring confronting the gasket is tapered to urge the gasket against the interior wall. A pressure increase within the container expanding the lid disk causes compression of the gasket, enhancing the seal.
