Abstract

A ring-type binder for retaining loose-leaf sheets of paper is disclosed. The binder has base and top members which are slidably secured to each other. Mounted to each of these members along and projecting from an edge are a plurality of half-ring members. With this configuration the base and top members can be slid between an open position and a closed position in which the half-rings of the top member are mated with the half-rings of the base member.
