Abstract: An apparatus and method for forming integral domed can bodies for aerosol cans. The apparatus is in the form of plural sets of tools, each set of tools including an inside tool and an outside tool so related as progressively to reduce the diameter of an end portion of the tubular body and in doing so gradually increasing the axial extent of an intermediate frustoconical portion. Each frustoconical intermediate portion is increased in extent axially by seating the previously formed portion on the inside tool and then shaping the blank on that same surface, whereby there is no interruption or stepping of the formed frustoconical intermediate portion of the blank.

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.
