ABSTRACT:
A plastic carrying case is constructed with a special elevated center divider and an inner depressed ledge portion and also with a special lower grooved portion that allows the center divider of a lower case to enter and be guided by the lower grooved portion of an upper case to facilitate movement of an upper case onto the ledge portion of the lower case. There is a special interrelationship between the center divider and the lower grooved portion of an adjacent case that assures rigidity yet facilitates intentional removal. The case walls are of thin construction for economy reinforced, however, by vertical beads through which compressive forces are transmitted.
