Abstract

A method of assembling the storage unit is disclosed. The storage unit includes a unitary sheet of material folded into an enclosure about a plurality of grooves. A cap formed from a unitary sheet of material is mounted above the enclosure and configured to provide usual or physical access to the top of the storage unit. The method comprises applying heat to a groove separating a pair of walls to melt at least a portion of the plastic material, and pivoting the walls so that the surfaces of the groove contact and join as the melted plastic material solidifies.
