An improved closure for fragile containers substantially filled with a gassy liquid, said closure comprising a combination of a cap for the container and a volumetric member partially within said cap and partially extending into the interior of the container. The volumetric member displaces and contains free gas generated by the gassy liquid thereby substantially reducing or completely eliminating the explosive potential of the container. The volumetric member is characterized by means that facilitate drainage of the gassy liquid should the liquid enter the member such as by expansion caused by elevated temperatures or inversion or shaking of the container.

A volumetric member for insertion into a fragile container for gassy liquids, said member having a thimble-like shape and having at least two openings extending through the walls thereof, one opening being above the other, the lower of said openings being of a size sufficient to permit liquid within said member to drain therefrom by gravity and the upper of said openings being smaller than the lower of said openings and of a size sufficient to permit pressure equalization between said member and a sealed fragile container into which said member Is inserted.
