1. A combination of a full panel opening end closure adapted for interconnection to a neck of a container and a complementing removal tool, comprising: a peripheral curl adapted for double seaming to a neck of the container;a chuck wall interconnected to said peripheral curl and extending downwardly therefrom;a countersink having a safety fold interconnected to a lower portion of said chuck wall, at least a portion of the countersink comprising a bearing surface;an inner panel wall interconnected to said countersink;a removable end panel interconnected to said inner panel wall, wherein said inner panel wall and said removable end panel are separable from said countersink about a circular score line;a generally circular shaped opening device in communication with said bearing surface of said countersink and comprising a helical ramp for contacting a portion of the end panel and separating the entire end panel from the end closure. 2. The combination of claim 1, wherein the end panel is retained by the opening device after separation from the container. 3. The combination of claim 1, wherein the end panel is secured to the container body by a peripheral curl. 4. The combination of claim 1, wherein the end closure comprises a folded bearing surface for contacting a lower portion of the opening tool. 5. The combination of claim 4, wherein the end panel is retained by at least two protrusions on an internal surface of the opening device. 6. The combination of claim 1, wherein the opening device comprises at least two ramps and wherein separation of the score is achieved by not more than 180 degrees of rotation of the opening device. 7. The combination of claim 1, wherein the ramp comprises a helically extending protrusion along at least a portion of an internal surface of the opening device. 8. The combination of claim 1, wherein the end panel comprises at least eighty percent of the area defined by the peripheral curl.
