Abstract
Abstract Two main rectangularly-shaped panels, each of said panels having projections on all four of its edges; four upper and four lower pieces having two thin walls which are separated by a partition to form an inside cavity, each of the pieces having distal ends forming 90 degree angles with each other; a cavity is formed in each of the pieces; four upper and four lower cornerpieces, all of the corner pieces having projections at either distal lateral end thereof, said projections being at an angle of 90 degrees from each other and tightly fitting into the appropriate cavities so as to form a detachable case.

A detachable case comprising: (a) two main panels, each main panel being flat and rectangular in shape, and having a first protrusion on each of four edges thereof, respectively; (b) four upper pieces, including two upper side pieces and two upper end pieces, each of said upper pieces being formed of two thin walls with an upper partition therebetween near an upper distal end, each upper piece comprising a channel set at an upper distal end of each of said upper pieces for receiving one of said first protrusions of one of said main panels, and a second protrusion set at a lower distal end of each of said upper pieces; (c) for lower pieces, including two lower side pieces and two lower end pieces, each of said lower pieces being formed of two thin walls defining a wall cavity and having a middle partition at upper distal ends thereof and at lower partition at lower distal ends thereof, each of said lower pieces having a respective channel at a lower distal end thereof for receiving one of said first protrusions of one of said main panels, and each of said lower pieces also having a channel for receiving one of said second protrusions at the upper distal end thereof; and (d) eight corner pieces, including four upper corner pieces and four lower corner pieces, each of said corner pieces forming a substantially 90 degree angle between two distal ends thereof, and having two projections, one of said projections at each of said distal ends of said corner pieces for respectively engaging with the wall cavity of one said side pieces and one of said end pieces; whereby the upper pieces and said one main panel, when the case is erected, form an upper case half having an upper case cavity with a downwardly facing opening, and whereby the lower pieces and the other main panel, when the case is erected, form a lower case half having a lower case cavity with an upwardly facing opening adapted with the downwardly facing opening to provide an enclosure with the case.
