ABSTRACT:
A dispenser for a stack of sheets disposed in a stack with each of the sheets having a band of adhesive coated on a portion of its bottom surface adjacent one edge by which the sheet is releasably adhered to the top surface, of the adjacent sheet in the stack, the sheets being stacked with the bands of adhesive of adjacent sheets at alternate opposite sides of the stack. The dispenser includes normally generally planar top wall formed by a single layer of resiliently flexible polymeric material and having two opposed portions with a slot therebetween through which the uppermost sheet in the stack can be withdrawn, whereupon the top wall portion adjacent the band of adhesive on the uppermost sheet will flex away from the stack to form a surface adjacent the stack along which the sheet being withdrawn and the end of the second uppermost sheet in the stack to which the band of adhesive on the sheet being withdrawn is adhered can slide, and the top wall portion opposite the band of adhesive on the withdrawn uppermost sheet will place drag on the second uppermost sheet in the stack so that the force applied to withdraw the uppermost sheet will peel the uppermost sheet away from the end of the second uppermost sheet in the stack after it is withdrawn through the slot rather than fully withdrawing the second sheet through the slot.
