Abstract
A stackable container assembly that is particularly suited for packaging heavy bulk products such as paint includes a container having a main body and a removable lid having an upstanding rim portion that has an upper surface. The container has a flexible bottom portion that has a lower surface that includes at least one support surface for supporting the container assembly on an underlying horizontal surface. The lower surface further includes at least one projection that is disposed radially inwardly from the support surface. The flexible bottom portion is advantageously configured so that the projection will flex radially downwardly and outwardly into a position that is adjacent to an upstanding rim portion of an underlying container assembly when the container assembly is stacked on top of another container assembly. This ensures accurate registration and positioning of the container assemblies during stacking.
