Abstract
The following specification discloses a magnetic disk storage case that can be used for such disks, as well as other magnetic memory materials common to computers and word processing. The storage case is formed from a single molded piece of plastic, such as polypropylene in the form of a clamshell or book-like case, having a top and bottom cover. The top cover receives a support ledge having flexible barriers thereon to maintain the magnetic materials stored therebehind on the ledge. The bottom of the case receives the ledge and the magnetic disks therein within a surrounding wall. The entire top cover with the ledge and the disks therein can be accessed by means of a resilient living hinge that allows for the lid to be opened into a clamshell configuration and supported against a stop member, against one of the edge walls, or by means of a channeled arcuate groove in combination with a pin that functions therewith.
