ABSTRACT:
This disclosure has to do with an easy opening container end wherein substantially the entire end panel is removed. The removable panel portion has rigidly attached thereto a pull tab which is first utilized as a lever to obtain the initial rupture of the end panel and then as a handle to tear out the removable panel portion. The removable panel portion is provided with a weakening line immediately adjacent the connection between the pull tab and the removable panel portion for the purpose of first venting the interior of a container and then forming a hinge which will permit the necessary pivoting of the pull tab relative to the end panel.
