Abstract
A ring binder has an elongate body and rings. Each ring includes ring members moveable between open and closed positions. The ring members and body can suitably formed together as one piece from a moldable polymeric material. The binder suitably includes a retaining system operable to selectively and releasably hold the ring members in the closed position. When the ring members are in their open position, loose-leaf pages can be added or removed from the rings. Loose-leaf pages can also be moved from one ring member to another when the ring members are in their open position.

(canceled)
A ring binder for use in holding loose-leaf pages, the ring binder comprising:
- an elongate body having a longitudinal axis;
- rings for retaining loose-leaf pages, each ring including first and second ring members extending from and supported by the elongate body, the first and second ring members being moveable relative to one another between a closed position in which the first and second ring members together form a substantially continuous, closed loop for allowing loose leaf pages retained by the ring to be moved along the ring from one ring member to the other and an open position in which the first and second ring members form a discontinuous, open loop for adding or removing loose-leaf pages from the ring;
- wherein the rings and body are formed together as a one-piece unitary structure made of a moldable polymeric material, the first and second ring members having free ends that are offset from each other in opposite directions along the longitudinal axis of the body.
