  • Patent number: 4397403
    Abstract: Disclosed is a container end with an integral opening apparatus which includes pull means for tearing a tab defined by a score line from the container end to form an opening. The score line is substantially U-shaped and the pull means is attached on the tab near the base of the U. Since the score line is U-shaped, the top of the U which defines one end of the tab is not severed from the container, thus the tab may be folded over the edge of the container end and maintained in a captured position out of the way of the user.

  • Patent number: 4345696
    Abstract: 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.
