The central opening has at least one locking flap disposed along a portion of the edge opposite the hinged mounting of the cover flap and the portion of the free edge of the cover flap within the area of the opening has slits extending from the edge, with the portion of the cover flap defined by the slits being pivotable out of the plane defined by the remainder of the cover flap.
