Abstract: A litter free beverage can lid or top having an inseparable opening tab. The tab has an arcuate shape to provide a cut edge underlying the can top in order that the tab can be pressed downwardly only. A sealant on the bottom of the can top provides a seal until the tab is opened by pressing downwardly. Hinging of the tab extends between the ends of an arcuate cut edge and scoring on the bottom of the lid may be used to facilitate hinging and minimize tearing. A slight inward tapering of the ends of the arcuate cut edge toward the hinge line may also be employed to minimize tearing and facilitate hinging. An enlarged boss on the top of the lid closely surrounds the tab and serves as a protective barrier against accidental contact of the tab by foreign objects such as other cans or the like to avoid accidental contact against the tab and premature opening.
