A plastic lid is coupled by a hinge to the ring, with the ring, the lid and the hinge being of one-piece integrally molded plastic construction. The lid has a skirt that is adapted releasably to be snapped to the ring in a closed position of the lid over the ring. The lid skirt may have an external bead that is adapted to be received by snap-fit within an internal channel on the ring in the closed position of the lid over the ring, and a conical internal surface on the ring may be provided to guide the bead on the lid into the channel on the ring.
