Closing ring for lid and container combination

摘要

A closing ring for a container and lid combination for securing the lid to the container includes a ring body (24) having first and second free ends (37, 38) to be drawn together in order to secure the lid to the container. A link clevis (32) and a lever clevis (34) are welded to the free ends. A link (33) is pivotally connected to the link clevis. A lever (35) is pivotally connected to the lever clevis. The linkage arrangement is completed by connecting the link to the lever at a third pivot connection (39a). A movable locking projection (36) is assembled to the lever clevis for engaging the lever during an opening attempt wherein the engaging prevents the opening of the ring body until the movable locking projection is moved out of its engaging position relative to the lever.
