Disclosed is apparatus for forming an opening in a sealed container. A score or weakening groove is formed in the container end to define a tab which includes a raised boss. An opening bar movable with respect to the container but affixed thereto is moved over the container end to contact the raised boss. The tab is thus depressed into the container and severed along the weakening groove to form an opening. The opening bar is positioned over the tab during shipment and during the initial opening procedure to protect the tab during shipment and to protect the user from the contents of the container during the initial opening procedure.

In a container end including a substantially flat disc-like body member having an outer major surface and an inner major surface and adapted to mate with a container body to form a sealed enclosure, the improvement comprising: (a) a partially severable tab defined by a weakening score line in said substantially flat member, said tab including at least one inclined boss projecting outwardly from said outer major surface; and (b) opening means comprising an elongated member disposed substantially diametrically across said end secured to said container adjacent said end and moveable in a plane substantially parallel with said outer major surface, said opening means covering said tab and said inclined boss; whereby movement of said opening means in said plane substantially parallel with said outer major surface causes said opening means to engage said inclined boss and depress said tab inwardly into said container by at least partially severing said tab from said end along said weakening score line.
