摘要： A cover assembly for a container includes: a cylinder base body with an axial bore therethrough, a lower portion for engaging an entry of the container, and an annular flange extending inwardly and radially into the axial bore; a shield mounted on an upper portion of the base body and having a central opening aligned with the axial bore of the base body; and a valve unit including a coil spring provided within the axial bore and placed on the annular flange, a hollow cylinder-shaped valve seat provided axially in the axial bore of the base body and inserted into the coil spring such that the valve seat can communicated with the container. The valve seat has an outwardly and radially extending press member which is biased by the coil spring toward the shield, and a blocking valve with a spherical external face and an axial hole extending therethrough. The blocking valve is provided resiliently between the valve seat and the shield and is connected pivotally to the shield such that the blocking valve is pivotable relative to the shield between a first position which permits access into the container and a second position which denies access into the container.
