Abstract
Abstract A protective storage case for tape cassettes includes a rectangular parallelepipedic box with two perpendicular open edge faces adapted to be opened or closed by a pivoting flap member including means for supporting a cassette to be stored in the box and for preventing rotation of the two hubs of the cassette. When several cases form a side-by-side collection, cassettes can be removed and inserted without removing individual cases from the collection.
