tear portion at locations on both sides of the hinge line.
According to a disclosed, preferred embodiment of the invention the pull tab includes a hingedly mounted attaching panel located intermediate the ends of the pull tab and extending away from the nose end thereof. The attaching panel is an integral part of the tab and is defined by a concavely shaped cut opening towards the nose end of the tab. The pull tab is connected to the tear portion of the container wall by at least one weld connecting the attaching panel of the tab to the tear portion of the container wall panel on the side of the hinge line away from the nose end of the tab and by at least one weld connecting the tabto the tear portion of the container wall panel on the side of the hinge line toward the nose end of the tab. The disclosed preferred embodiment of the method of the invention involves welding the tab to the container wall on both sides of the hinge line by means of a high energy density welding process wherein the energy density is at least 10.sup.6 watts/inch.sup.2 such as with laser welding.
By attaching the tab to the tear portion of the container wall at locations on both sides of the hinge line of the pull tab, the alignment of the tab on the container wall is maintained so that the nose end of the tab remains positioned adjacent the line of weakness in the container wall and at the
