2109097 9219506 PCTABS00017 Easily removable press-on, pry-off closures having movable insert disks in an outer shell are disclosed. Pressing the shell (14) upward to remove it from a container (11) first pries a protrusion (28) inside the shell over a snap rib (22) around the container, then moves the shell upward relative to the disk (16) while the latter remains seated on the container, until a disk-lifting projection inside the shell engages the edge (48) of the disk and lifts the disk to break the seal. A tamper evidencing band (32), if included, is broken before either the shell is pried off or the disk is lifted. The invention can be used in both top load and bottom load embodiments. Also disclosed is a closure with a non-movable disk or integral top and a tamper-evidencing band which is broken by pry-off removal of the closure.
