Abstract:
A sheet metal lid has a rim portion removably secured and sealed to a container and the lid includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. The flange portion of the button has a short arcuate score or shear line extending substantially into the sheet metal, and additional score lines extend into the flange portion at lesser depths to protect a coating on the inner surface of the lid. A resilient sealant material may be bonded to the inner surface of the vent button, and the opposing sheet metal portions of the score line form a small gap for releasing a vacuum or pressure from the container in response to a controlled downward pressure on the top wall portion of the vent button.

Claim (Index 11):
A method of adding a vacuum or pressure release button to a sheet metal lid having a vertical axis and a peripheral rim portion adapted to be secured to the top end portion of a container for a product and having a vacuum or gas pressure, the method comprising the steps of\n pressing a portion of the top wall of the lid downwardly to form an upwardly projecting vent button, forming the vent button with a top wall portion and a surrounding side wall portion extending to a flange portion projecting laterally outwardly from the side wall portion, forming a downwardly projecting bead within the flange portion adjacent the side wall portion of the vent button, shearing an arcuate portion of the flange portion between the side wall portion and the retention bead to form an arcuate shear line extending substantially through the metal thickness of the flange portion, compressing a top surface and a bottom surface of the flange portion along the shear line between opposing tooling members to select the downward force required on the top wall portion of the vent button to shear the sheet metal at the shear line, and bonding a sealant material to an inner surface of the vent button below the shear line and effective to define a vacuum or pressure release gap in response to depressing the top wall of the vent button above the shear line for releasing vacuum or gas pressure from the container.
