Abstract: An article hanger or keeper comprises a wire formed as a major portion of one turn of a geometric solenoid with two hook end portions having bent-back ends which include bends of approximately .pi. radians (180.degree.) around a radius approximating the diameter of the wire, to provide hangers which may be used singly or in series. The hangers are easy for a human to install and lock or unlock, without a need for any auxiliary tool, but very unlikely to become accidentally unlocked. One disclosed embodiment utilizes a slightly elliptical turn, which renders the hanger self-orienting to deter one type of accidental unlocking.
Abstract: An article container is formed by two generally interlocking wire sheet pieces which fold together in clamshell fashion to provide a container for articles to which access may be had.
