Abstract
A connector is used to securely attach two nested, stacked buckets so they may be easily transported using the handle on the upper bucket but also maintains an air gap between the sidewalls of the buckets when in a nested, stacked configuration, enabling the buckets to be easily separated. Each bucket connector includes a biasing arm extending downward from an apron formed on the buckets. The biasing arm includes a hook that automatically engages the upper lip onto a lower bucket when the upper bucket is stacked inside the storage cavity formed in the lower bucket. The biasing arm disengages the hook from the upper lip. Formed on the biasing arm is a stop surface configured to limit the downward movement of the upper bucket into the storage cavity. The stop surface forms an air gap between adjacent sidewalls when the upper bucket is stacked over the lower bucket.
