US Patent 6902061 Collapsible liquid box

A collapsible box for storing liquids, the box capable of being stacked while filled and then collapsed for convenient storage and return shipping when not filled. The box includes a base having a lip extending upwardly along the edges of the bottom panel. An upper sleeve is connected to the base by a base hinge, the upper panel being foldable by way of several other hinges to either an open or a closed position. A lid has a lip extending downwardly to selectively surround the top edges of the upper sleeve when the upper sleeve is in the open position, thereby forming an enclosure.
