Abstract: An apparatus for securing a free edge of a security cover relative to a free edge of a finery case containing jewelry, precious metals and the like. The apparatus includes an elongate coupling member having first and second open channels formed therein. The free edge of the security cover is fastened within the first open channel. An elongate locking channel includes an elongate coupling edge and a J-shaped cross section, with the coupling edge fastened within the second open channel of the coupling member. The second open channel of the coupling member and the coupling edge of the locking channel include correspondingly-shaped cross sections having corners to enable the coupling edge to interlock within the coupling member. The locking channel is configured and dimensioned to interlock around the free edge of the finery case when the cover is placed against a sidewall of the case and further secured relative to the case, to thereby secure the free edge of the cover relative to the free edge of the case.

Abstract: A protective cover for finery cases containing jewelry, precious metals and the like. The cover is made of nontransparent plastic sheets which are hinged together. A J-shaped channel is disposed on the free edge of one of the sheets for interlocking around a lower lip of a jewelry case. The plastic sheets correspond in size to the walls of the jewelry case to permit the sheets to hingedly extend around the edge corners of the case so that each plastic sheet is coextensive with and covers an outer glass-paneled wall of the case. The free edge of the cover opposite the J-shaped channel is locked to the case to prevent removal of the cover, which renders the case nontransparent.
