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 29):
A sheet metal lid having a vertical axis and including a top wall and a peripheral rim portion with a bonded sealant material, and adapted to be releasably secured to a container receiving a vacuum or pressure enclosed product, the lid comprising,\n a portion of the top wall defining a vent button having a top wall portion, a surrounding annular side wall portion with an outwardly projecting flange portion extending around the side wall portion below the top wall of the lid, the flange portion having a first score line extending into the flange portion adjacent the side wall portion of the button and projecting substantially into the thickness of the sheet metal forming the flange portion, a second score line within the flange portion and spaced radially outwardly from the first score line, the second score line extending into the flange portion at a depth less than the depth of the first score line, the first score line being effective to rupture without rupturing the second score line in response to a predetermined downward pressure on the top wall portion of the vent button to define a narrow gap along the first score line for releasing vacuum or pressure from the container, and a third score line extending into the flange portion at a depth less than the depth of the second score line and cooperating with the second score line to minimize distortion of the flange portion when the flange portion flexes downwardly before the first score line is ruptured.
