ABSTRACT:
An easy-opening closure for cans containing beverages and liquids which is actuated by means of a lever and spring fulcrum member affixed to a sliding closure member formed integrally with the can lid by sequential punching and die forming. In the two step opening sequence, the lever is first lifted to break the seal, form a vent, and allow the spring fulcrum element to engage a pivot groove formed in the can lid, after which downward force is applied on the lever to displace the sliding closure member toward the center of the can, guided, and retained by grooves in the side of the opening in the lid. The closure remains attached to the container lid after opening.
