A plastic bucket lid is adapted for removable attachment adjacent its periphery to a bucket. The lid defines an annular open depression adjacent its periphery, and, positioned outwardly from the depression, an annular locking slot for receiving and holding the lip of a bucket. In accordance with this invention, radially-positioned reinforcing fins are carried by the lid within the annular, open depression to restrict the flexing of its outer wall. This, in turn, has been found to reduce the tendency of the lid to be knocked off of a bucket upon being dropped or the like. Preferably, an outwardly positioned annular projection is placed in the locking slot which defines an angle of 80°to 100°to the plane of the annular walls defining the locking slot for improved retention of the lid to the bucket.
