Abstract
A blow-molded unitary structure includes a panel having first and second panel walls and a generally hollow interior between the first and second panel walls. The structure also includes one or more different types of strengthening elements monolithically formed with the panel and across a substantial portion of the panel to enhance the strength of the structure. A strengthening element can be a depression recessing from the second panel wall toward an interior of the panel, a protrusion protruding from the second panel wall toward an exterior of the panel, a rib protruding outwardly toward the exterior of the panel and a trench formed by side walls of adjacent protrusions.

A blow-molded unitary structure comprising:
- a panel comprising a first panel wall and a second panel wall spaced apart from the first panel wall;
- a plurality of depressions monolithically formed with the panel, each recessing from the second panel wall toward an interior of the panel, wherein each depression in the plurality of depressions comprises:
- an open depression top at the second panel wall;
- a closed depression bottom opposite to the open depression top;
- and
- a depression side wall connecting the open depression top and the closed depression bottom;
- and
- a plurality of protrusions monolithically formed with the panel, each protruding from the second panel wall toward an exterior of the panel, wherein each protrusion in the plurality of protrusions comprises:
- an open protrusion base at the second panel wall;
- and
- a closed protrusion cover surrounding the open protrusion base;
- wherein depressions in at least a subset of the plurality of depressions are arranged alternately with protrusions in at least a subset of the plurality of protrusions across at least a portion of the panel, and wherein the plurality of depressions and the plurality of protrusions collectively enhance a strength of the blow-molded unitary structure.
