Abstract: A closing ring for a container and lid combination for securing the lid to the container includes a ring body having first and second free ends to be drawn together in order to secure the lid to the container. A link clevis and a lever clevis are welded to the free ends. A link is pivotally connected to the link clevis. A lever is pivotally connected to the lever clevis. The linkage arrangement is completed by connecting the link to the lever at a third pivot connection. A movable locking projection is assembled to the lever clevis for engaging the lever during an opening attempt wherein this engaging prevents the opening of the ring body until the movable locking projection is moved out of its engaging position relative to the lever.

Abstract: A composite closure for a container having a ring shaped cap with a ring shaped top and an annular skirt depending downwardly from the outer periphery of the top. The skirt is provided with internal threads for engaging external threads on the container neck. A disk shaped lid insert has its outer peripheral edge annularly received in an annular internal lid retaining groove in the cap which permits relative rotation between the lid insert and the threaded cap. An elastic annular seal is received in an annular groove provided in the bottom side of the lid insert for sealing the upper edge of a container.
