Container for holding flat, thin objects

Abstract

A data cartridge case has a generally rectangular base and cover joined to the rear wall of the base by a living hinge. Top edge of the base front wall is lower than top edge of the rear wall. The top edge of the base front wall and the bottom edge of the cover front wall have horizontal outer portions and chamfered inner portions. Cover side walls have half-thickness lower sections overlapping half thickness forward sections of the base side walls. Upper horizontal edges of the half thickness portions of the base side walls abut complementary lower ledges of the cover side walls. Central rectangular inward projection on each cover side wall half thickness portion fits in a rectangular recess in each base side wall half thickness portion. Notches in the cover front walls allow finger pressure to frictionally raise the cover and to snap the rectangular projections out of the recesses. A groove extends across the entire cover front wall at the height of the hinge for receiving a hinge of an adjacent container. Inner surfaces of the base and flat outer surfaces of the front and rear walls of the base are tapered. Other outer surfaces of the base are formed with no draft ridges to provide straight stacking and prevent sliding. Inner cover side walls and upper portions of base side walls have abutting downward and forward sloping rear edges and horizontal lower edges for aligning the cover precisely with the base in a closed position.
