A unitary molded plastic cover for a container such as a medicament vial is disclosed in which a removable cap portion is attached by a severable tear strip. A pull ring is disposed around the cap portion and attached to the tear strip through torsion hinge sections which permit pivoting of the ring from its surrounding position to a raised access position for gripping and pulling to remove the tear strip and the cap.
