A plastic container and removable interlocking lid where the upper end of the container includes radially outer and radially inner upright annular flanges together with a bottom wall which forms a U-shaped annular rim defining an upwardly facing annular trough. The lid includes a first radially outer depending annular wall which fits down within the U-shaped annular rim and locks therein for removably locking the lid to the top of the container. The upwardly facing trough includes at least one annular groove the upper end of which is defined by a substantially flat surface which locks against a substantially flat annular shoulder formed on the first depending lid wall. In a preferred form, the base of the trough is formed of a plurality of sloping surfaces, and drain holes are located in the trough in communication with the interior of the container, the drain holes being located at the lower portions of the sloping surfaces.
