The lid is compression molded from a plastic material such as medium density polyethylene, and has a planar upper surface and a planar lower surface. In one embodiment, a plurality of generally parallel spaced apart recesses are formed in the lower surface. The recesses are spaced inward of the outer edges of the lid. The area of the lower surface of the lid is greater than the total area of the recesses in the plane of the lower surface. In another embodiment, an opening leading to a cavity is formed in the edge of the lid with a press fit passage for receiving a transponder device.
