A container cover for use with a container having a neck with a rim. The cover includes a lid, a skirt extending downward from the circumference of the lid, a concentric plug seal extending downward from the lid inside the skirt, a hinged lock and at least one non-hinged lock, each lock having an inwardly projecting wedge, which lock the cover in place on the container by engaging the bead ring. The non-hinged lock preferably includes a slot through the skirt and the locking wedge, to provide flexion and facilitate removing the lid. When the cover is locked on the container, the plug seal provides a seal against the inside of the container neck. An optional spout hole and spout door can be provided, wherein the spout door seals the spout hole when closed and prevents unlatching of the hinged lock when open.
