Abstract

The disclosure is of a stacked structure made up of a plurality of identical box-like units arranged one atop the other in a near vertical array in which each unit presents a front face angled to the vertical in such fashion that the front face of each unit forms a dihedral angle with its next lower and next upper unit. Each unit has a floor and a roof that diverge rearwardly relative to each other which causes each upward unit, resting via its floor on the roof of the next lower unit, to tilt forwardly so that its front face is at a lesser angle to the vertical than the angle between the front face of the next lower unit and the vertical. The configuration is such that the increments by which the angles decrease from bottom to top are equal. The units are basically transparent to expose the unit contents and each unit has a dispensing means in its rear part.
