A bucket lid made of flexible plastic defines a gripping channel for receiving the bucket, and an annular inner channel made of the wall of the lid, projecting outwardly relative to an attached bucket. Manual depression of a point of the inner channel with the finger causes the outer wall of the gripping channel to disengage a bucket lip retained in the gripping channel. This permits the lid to be peeled off of the bucket for opening.
