Unitary holder for two CD boxes which can be combined with one or more identical holders for storing a plurality of CD boxes

A unitary holder device for holding two protective CD boxes in which compact discs are stored, wherein said device can be combined with one or more of the same devices to store a plurality of such protective CD boxes, with the CD boxes being positioned in a stack one upon the other such that hinges of the CD boxes are all located on one side of said stack and with the hinge on each respective CD box being in alignment with pivotable engagement means on the respective holder devices that hold the devices together in their operative position, and further wherein any individual box in the stack thereof can be pivoted open to gain access to a compact disc therein without removing that box from the stack of boxes and without opening any other boxes or removing any of the other boxes from the stack of boxes, said holder device comprising

• a pair of side rails that are substantially parallel with each other;
• means for spacing the side rails apart from each other such that a first CD box can be received and held between said side rails with the hinged end of said first CD box lying adjacent to a straight line between respective one ends of said pair of side rails;
• a first lip or tab that projects upwardly from one end of said device, said first lip or tab being formed between said one ends of said pair of side rails such that the first lip or tab extends away from a hinged end of a first CD box when said first CD box is received between said pair of side rails;
• a second lip or tab that projects upwardly from a second end of said device opposite said one end such that said second lip or tab extends away from an opposite end of a first CD box when said first CD box is received between said pair of side rails;
• said first and second lips or tabs being spaced such that a second CD box can be received and held between said first and second lips or tabs, with a hinged end of said second CD box lying above and next to the hinged end of a first CD box when said first CD box is received between said pair of side rails;
• and
• engagement means at the one ends of said pair of side rails for pivotally attaching a second holder device to said first holder device such that said first holder device can pivot about said second holder device.
