Zusammenfassung:	A pull tab opener for a container having a push-in closure is articulated at a crease line behind the rivet connecting the tab to the container top surface. At least one protrusion extends upwardly from the base of the tab so that, when the rear lever portion is articulated about the crease line, to an amount at least in the range of 110° to 160°, and interference between the at least one protrusion and a cooperating face portion occurs, and the push-in closure is opened. There may also be cooperating protrusions. Another embodiment provides an undercut notch at each end of the crease line in the tubular peripheral edge of the pull tab opener.
