Abstract
Abstract A container lid, by the steps of shear-coining over die surfaces to provide a fracture, and a swedging, comprises a peripherally dilated button portion which adequately resists internal fluid pressures, yet is disruptable by external finger pressure urging the button portion inwardly. The fracture terminates within a wall of the button portion, being sealed by surfaces preferably swedged into overlapping relation. The button may be provided with a non-disruptable or hinge portion, or formed to enable it to fall into the container, the button in either case not being separately disposable. No harmful closure edges are exposed.

Claim 9
Dependent Claim
78 words

Claim 10
Dependent Claim
26 words
A lid as in claim 6 wherein swedged metal from a peripheral wall of the indentation overlaps the fracture at said bottom face for sealing it.
Claim 11
Dependent Claim
97 words
A sheet metal container lid comprising an integral, disruptable pop-in type of button closure, the closure being largely defined by a continuous depression in the lid, and a bounding wall which, in section, is generally angularly related to the lid, a longitudinal indentation in the bounding wall, a fracture terminating interiorly of the wall substantially at the bottom of said indentation, and at least a portion of the metal adjacent to a peripheral face of the indentation being dilated to partly overlap the bottom surface of the indentation substantially at the interior terminal portion of said fracture.
Claim 12
Dependent Claim
97 words
A sheet metal container lid comprising an integral, disruptable pop-in type of button closure, the closure being largely defined by a continuous depression in the lid, and a bounding wall which, in section, is generally angularly related to the lid, a longitudinal indentation in the bounding wall, a fracture terminating interiorly of the wall substantially at the bottom of said indentation, and at least a portion of the metal adjacent to a peripheral face of the indentation being dilated to partly overlap the bottom surface of the indentation substantially at the interior terminal portion of said fracture.
Claim 13
