Tote box with corner enhancers and top rail

A tote box with a self-locking top rail comprising:

• a box formed from a foldable box blank of a uniform thickness, said box having a bottom, two opposed side walls and two opposed end walls, said side walls and end walls having upper edges defining a top edge of the box, at least two said walls having tabs on said upper edges thereof which are downwardly folded,
• four corner enhancers, each corner enhancer joining one of said end walls to one of said side walls, each corner enhancer having first and second open leg channels each formed between a pair of leg channel walls, each of said open leg channels having an uninterrupted width defined between planar inside surfaces of said leg channel walls, said width of said open leg channels being substantially the same as the thickness of said box blank so as to frictionally hold inside said first and second open leg channels one of said side walls and one of said end walls, and
• a top rail extending around the top edge of said box, said top rail having a downwardly open channel formed between a pair of channel side walls, said downwardly open channel being fitted over said upper edges of said side walls and said end walls, said downwardly open channel having a width of approximately twice the thickness of said box blank so as to fit over said downwardly folded tabs, and an upper portion of each of said corner enhancers,
• said side and end walls of said box being maintained in an assembled relationship solely by interengagement of said top rail with said tabs.

• a plurality of corner enhancers, each of said corner enhancers having first and second open leg channels, each of said open leg channels being formed between a pair of leg channel walls, one of said end walls being located inside one of said first and second open leg channels and one of said side walls being located inside the other of said first and second open leg channels, and
• a top rail extending around the top edge of said box, said top rail having a downwardly open channel formed between a pair of channel side walls, said downwardly open channel being fitted over said upper edges of said side walls and said end walls and an upper portion of each of said corner enhancers, said downwardly open channel having a width of approximately twice the thickness of said box blank so as to fit over said downwardly folded tabs of said side walls and said end walls, at least one of said channel side walls having an inwardly extending hook, each said hook engaging one of said tabs and locking said top rail over said upper edges of said end and side walls,
• said side and end walls of said box being prevented from separating from said corner enhancers solely by interengagement of said top rail with said side and end walls.
