Abstract

Abstract A tray for a stack of note paper has an inclined bottom wall on which the stack rests. The tray has supports so that it can be placed on a flat surface. At the lower end of the bottom wall is an outwardly inclined end wall against which the lower end of the stack bears. The upper end wall of the bottom is spaced from the adjacent edge of the stack. Approximately midway of the bottom wall is a depression of substantial depth and formed by two downwardly inclined wall portions which meet at their lower edges. In order to free the upper sheet from the stack the stack is pressed downwardly by a thumb or finger into the depression, thereby bending the stack and causing the edge of the uppermost sheet to flex free and be grasped conveniently and peeled from the remainder.
