Abstract: This invention is directed toward a flat, washer-like key ring. In some embodiments, the key ring is substantially circular. It is distinct from prior art in that the key ring largely, or entirely, resides in a single plane, as opposed to being concentric circles overlapped one on top of the other. The key ring has a split line running through a portion of its body. The split line creates inner and outer segments along a portion of the plane of the body. The split line can be non-linear, in that it may not be a straight line. As such, the split line has protrusions and slots running along its length. These protrusions and slots interact mechanically to allow the key ring to remain securely closed, and endure greater radial forces, by coupling the inner and outer segments together. The inner and outer segments are also releasably attached so as to facilitate the addition or removal of a key.

Abstract: An identification system utilizes a plastic housing which is appropriately sized to hold either a key or a coin as well as an information sheet on which the user may place selected indicia referring to the key or to himself. Each embodiment utilizes a living hinge closure attachment to secure the key or coin and information sheet within the housing. Utilizing the housing and indicia for identifying the key minimizes the excess material and connections thereby simplifying the identification and storage problem, yet because the use of the housing with the key slightly increases the size of the key head, it provides a slightly greater moment arm for turning the key in a lock and gives a slightly larger gripping surface to be employed when so turning the key. These factors are significant when dealing with children and with elderly people who may not have the physical strength and dexterity required for some small headed keys.
