FIELD: chemistry.
SUBSTANCE: closure for a container contains calcium hydride and a matrix material as a hydrogen-generating composition. In the application generated is hydrogen, which reacts with oxygen, penetrating into the container, connected with the closure, and a catalyst, bound with the closure, and a catalyst, bound with the container, catalyses a reaction of hydrogen and oxygen, which results in getting water, with an absorption of oxygen.
EFFECT: invention provides the high rate of reaction and high ability to initiate absorption reaction in the process of the container filling.
