Abstract
A closure () for a container incorporates calcium hydride and a matrix material as a hydrogen-generating composition. In use, hydrogen is generated which reacts with oxygen permeating a container associated with the closure and a catalyst associated with the container catalyses reaction of the hydrogen and oxygen to produce water, thereby scavenging the oxygen. The composition of calcium hydride and matrix is also claimed.
