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.
Claims10
An apparatus for sealably mounting a bottle having a fill ring and a closure cap fitted over a closure cap region above the fill ring, for measuring the gaseous leakage through the closure cap region, comprising:
- a) a fixture having respective horizontal and vertical braces thereon;
- b) an adjustable clamp mounted on each of said horizontal and vertical braces, each of said adjustable clamps having a movable plunger capable of being locked into a fixed positon;
- c) a positionable collar attached to one of said movable plungers, said collar having means for supporting the fill ring of said bottle;
- d) a closure cover attached to the other of said movable plungers, said closure cover being movable to completely overlie the closure cap of said bottle, and be movable to become sealably positioned against said positionable collar.
An apparatus for holding a container and container closure in fixed position for measuring gas leakage through the closure, comprising
- a) a container neck clamp which is positionable about the neck of said container, and lockable into a fixed position;
- and
- b) a closure cover movably positionable over said container closure and said container neck clamp, and lockable into a fixed position against said container neck clamp;
- and
- c) means for sealing said container neck clamp and said closure cover together, thereby to provide a sealed chamber for the collection of gases leaking through said closure and through the region between said closure and said neck.
