  • Patent number: 4143788
    Abstract: An improved child resistant end closure wherein the pull tab for an easy opening end is mounted within a panel bead; the tab being fastened by the rivet to a tear-out portion of the end panel. The tear-out portion is adapted to be pulled outwardly about a hinge line which intersects the bead. The bead is reduced in depth at the intersection with the hinge line and formed to permit the bead to fold in such manner as to resist sudden flip-out of the tear-out portion which in the previous designs has caused splashing out of the contents in the container.

  • Patent number: 4084722
    Abstract: An improved child resistant end closure wherein most of the pull tab for an easy opening end is mounted within a bead formed on the end panel which obstructs access to the ring or lift portion of the tab and pevents grasping and lifting it. The tab and/or the end panel are slightly bowed in such manner that the tab upon fastening by the rivet to the end panel is sprung toward the end panel so that the ring portion of the tab is biased toward the panel below the bead. The shape of the bead and the ring or grasping portion provides a digitally operable structure which permits an adult to insert his nail between the tab and external bead to lift the ring while flexing the end panel so that the ring may be further lifted to break free the tab hinge and then break the score defining the openable segment of the end panel, or alternatively the lift portion may be pried up by a tool entered into a slot provided beneath the ring.
