Container and lid combination with closing ring assembly
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 link is connected to the lever at a third pivot connection that travels in a lever slot. The linkage arrangement is completed by the addition of a pair of closing links that are pivotally connected together and connected to the lever at the lever clevis location and to the lever at the third pivot connection.

13. The closing ring of claim 1 wherein said link is connected with the second end of said ring body by pivotal connection with a link clevis member that is joined to said second end.
14. The closing ring of claim 13 wherein the connection of said link member and said link clevis member includes a link pivot member that is inserted through said link clevis member and through said link member.
15. A closing ring for a container and lid combination for securing the lid to an open end of said container, said closing ring comprising:
a ring body having a first free end and a second free end, wherein said first and second free ends are drawn toward each other as part of manipulating said closing ring to secure said lid to said container;
a lever pivotally connected at a first end with said first free end of said ring body at a first pivot axis, said lever being constructed and arranged for opening and closing said ring body by pivoting about said first pivot axis;
a link member pivotally connected at a first end with said second end of said ring body and pivotally connected at a second end to said lever at a second pivot axis;
a first closing link having a first end and an opposite second end;
a second closing link having a first end and an opposite second end; and
wherein the first end of said second closing link is pivotally connected to the second end of said first closing link, the first end of said first closing link being pivotally connected with said lever and said link member at said second pivot axis, and the second end of said second closing link being pivotally connected with said lever at said first pivot axis.
16. The closing ring of claim 15 which further includes a spring-biasing structure used in combination with said first and second closing links.
17. The closing ring of claim 16 wherein said lever is connected with the first end of said ring body by pivotal connection with a lever clevis member that is joined to said first end.
