Abstract
A fixture for holding a plastic or glass container and container closure member in a fixed position for measurement of the gases escaping through and around the closure member. A first clamp positions a closure cover over the closure member, and a second clamp positions a slidable yoke about the bottle neck, wherein the first and second clamps are sealably affixed together; the closure cover has a gas passageway for purging the gas from the chamber formed by the two clamps, and for collecting gas leaking through the closure member.
