ABSTRACT:
A plastic bucket having a lip which defines means for engaging a bucket lid in sealing relation. The interior wall of the bucket defines an annular, inwardly projecting ridge spaced from the lip. The ridge extends around the inner circumference of the bucket, and defines an annular, inwardly pointed apex, to provide increased hoop strength to the bucket adjacent to its mouth and to provide an internal brush wiping member within the bucket.
