A container and a method of forming a container having a locking closure and a method of forming the locking closure. The container includes bottom, side and top walls and at least one of the walls being an opening wall formed of panels which provide an opening to an interior of the container and which overlap to provide the locking a closure of the opening wall. In a closed condition of the container, a bottommost panel of the opening wall is partially overlapped by adjacent panels of the opening wall and a topmost panel of the opening wall located opposite the bottommost panel partially overlaps the adjacent panels and the bottommost panel. A tab of the bottommost panel is lifted upwardly to partially overlap the topmost panel to form the locking closure.
