A storage case for flat, uniformly shaped quadrilateral objects such as floppy disks includes a rectangular box like lid and base portions hinged to both sides of a central spine portion. Inside each of the base and lid portions two pair of ribs are provided for firmly gripping a floppy disk, or the like, inserted therein. The ribs may include a pressure applying first rib opposed to a top gripping second rib for added security. A central spine of the case includes additional ribs for grippingly engaging a third floppy disk which may thus be held separately from the disks inserted in the base and lid such that three disks may be securely held without rattling. The edges of the case are provided with three closing members corresponding to three engaging members to assure secure closure and, in addition, mating edges of the side wall portions may be formed at compatible angles which interlock in a closed condition of the case preventing plastic deformation thereof when the case is carried. Further, the base and/or lid may be hinged at a central portion thereof for allowing partial opening of the case while the main part thereof remains closed.
