Abstract
A closure for lids made of sheet metal and secured as by a folded seam to the container body of cans and the like comprises, formed on the lid, a circular line of weakening and a circular groove adapted for engagement by a teaspoon or the like, to pry open the can, the groove having a U-shaped cross-sectional configuration and the line of weakening being a substantially V-shaped nick formed in the groove bottom close to the inboard wall thereof. This closure affords easy-opening features for the can using a teaspoon for a lever, while making the can virtually break-proof against undesired opening due to incidental shocks in handling and in transit.
