Claims5
An easy opening container having a substantially tubular body and an easy-opening end closure seamed to one end of the body, the closure having a removable panel defined within a non-removable part of the closure by a line of weakness, wherein the improvement comprises a band bonded to the underside of the removal panel and arranged to span the weakening line and to underlie the non-rmovable part so as to mask the torn edge of the panel after removal of the panel from the closure, the combination further including a radially inwardly projecting fold formed integrally from the material of the closure and overlying said line of weakness to mask the torn edge of the said non-removable closure part on removal of the said removable panel.
An easy opening container comprising a tubular body and a closure secured to one end of said body by a seam, said closure including an end panel, said body having a circumferentially disposed continuous bead inwardly directed and underlying said end panel in closely spaced relation thereto, said closure being of the easy opening type and including a circumferential score formed in said end panel in overlying relation to said bead, said score dividing said end panel into a removable panel portion and a non-removable panel portion, said non-removable panel portion having an inner periphery overlying said bead, and a band bonded to said removable panel portion and extending across said score and overlapping said non-removable panel portion, at least a portion of said band being disposed between said bead and said non-removable panel portion, said band being arranged to mask the edge of said removable panel portion and said bead being arranged to mask the edge of the non-removable panel portion when said removable panel portion is removed.
