Abstract: A construction for a digitally openable container closure which includes at least one inwardly displaceable opening panel each of which is defined by a fracturable web forming a locus of separation of the opening panel from the adjacent portion of the closure, an integral deflectable portion projecting outwardly from the closure adjacent the fracturable web around each opening panel and weakening lines in the closure adjacent each opening panel extending across the closure between the opening panel and a central panel of the closure to facilitate displacement of the deflectable portion of the wall in response to digitally applied inwardly directed pressure to initiate fracture of the web and permit inwardly displacement of a separated opening panel.
