Abstract
Abstract A sort tray characterized by two sorting sections hinged together along a common wall. The sorting sections, which are substantially mirror images of each other, can be folded together to allow compact storage of the sort tray. Sliding gates are provided at the mouths of the sorting sections to permit the contents of one of the sorting sections to be poured out without pouring out the contents of the other section.
