The design comprises the ring binder having spaced rings of opposed sections which in the closed position have an ovate or egg shape as seen in end view, being somewhat flattened at the top. Each ring section extends closely adjacent the associated edge of the central spine in both open and closed positions of the ring binder, the ring sections being bent tightly against the edge of the spine, but not passing through any notch in the spine.In the drawings:Figure 1 is a perspective view of the ring binder embodying the design, the rings being shown in closed position;Figure 2 is a view similar to Figure 1 showing the rings in open position;Figure 3 is a bottom plan view;Figure 4 is a top plan view;Figure 5 is an end view showing the rings in closed position; andFigure 6 is an end view showing the rings in open position.
