Abstract
A sheet metal lid has a rim portion with a resilient sealant for releasably coupling and sealing the lid to a glass or other container enclosing a vacuum food product. The lid is successively pressed with progressive dies to form an upwardly projecting and thinner dome-shape portion which is progressively formed into annular cavity surrounding a vacuum release vent button. The button has a sloping top wall with an upper edge portion connected to a substantially vertical arcuate wall portion adjacent an arcuate score line located in opposing relation to an arcuate reinforcing bead within the cavity. A sealant material is bonded to the inner surface of the button and overlies the score line. The vent button is preferably located below the rim both before and after the vacuum is released, and the sealant material reseats to cover the score line and protect the food product.
