Abstract
A case for flat objects (e.g., shells containing disc-shaped recording media) includes a pair of case walls, a bottom wall and opposed side walls attached to the case walls. The opposed side walls maintain the case walls in parallel separated relationship and establish an open end of the case opposite to the bottom wall. The side walls are provided with respective L-shaped cut-out regions having edges which establish respective resilient tabs. One end of each tab is connected to a respective one of the side walls while the opposite terminal end of each tab is unconnected to the side wall. The resilient tabs each include a notch formed in their end which is connected to the side wall. The notch thereby establishes a hinge region to allow the resilient tabs to be deflected inwardly of the case and thereby be in resilient contact with a lateral edge of a flat object within the case. The notch causes the resilient tab to be extended lengthwise so that the unconnected terminal end thereof is partially overlapped with a respective edge of the cut-out region. In such a manner, the unconnected terminal ends of the tabs are maintained inwardly of their respective side wall. Due to the resil…
