The lid is used to cover a utility box which houses a meter such as a water meter. 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.

The invention claimed is: 1. A lid for a utility box, comprising: a member molded from a plastic material and having spaced apart upper and lower sides, said lower side comprising a lower surface having an outer edge, an opening formed in said outer edge of said member by wall structure and leading to a cavity for holding a transponder device, the transponder device is of the type having a stem extending from a housing, said opening having a portion for receiving the stem of the transponder device such that the housing may be located in said cavity by way of said opening with the stem extending through said portion of said opening, said opening having a passageway with a width normally less than the width of the stem which passageway may be expanded by pressure applied to said wall structure by the stem to allow the stem to be moved through said passageway to allow insertion and removal of the stem into and from said portion of said opening by way of said passageway, when the stem is located in said portion of said opening, the pressure applied to said wall structure is released such that said wall structure will hold the stem in said portion of said opening and hence the housing in said cavity. 2. The lid of claim 1, wherein: said passageway comprises a wall formed of plastic material having a thin portion of plastic material which extends into said passageway in an at rest portion to define a minimum width of said passageway and which can be moved to a position to expand the width of said passageway by pressure applied to said thin portion of plastic material by the stem of the transponder to allow passage of the stem through said passageway and when said pressure is released, said thin portion of plastic material returns to said at rest position. 3. The lid of claim 1, wherein: said passageway comprises two spaced apart wall portions formed of plastic material each of which comprises a thin portion of plastic material which extends into said passageway at an at rest position to define the minimum width of said passageway and which can be moved to a position to expand the width of said passageway by pressure applied to said thin portions of plastic material by the stem of the transponder to allow passage of said stem through said passageway and when said pressure is released said thin portions of plastic material return to said at rest positions. 4. The lid of claim 1, wherein: said outer edge extends around said member next to said lower side and which faces outward of said member, said lower surface is contiguous with said outer edge at least on two opposite sides of said outer edge. 5. The lid of claim 1, wherein: said outer edge comprises a first pair of spaced apart outer edges which face in opposite direction from each other outward from said member and a second pair of spaced apart outer edges which face in opposite directions from each other outward from said member, said first pair of outer edges are transverse to said second pair of opposite edges, said lower surface extends to and is contiguous with said first and second pairs of outer edges. 6. The lid of claim 1 in combination with a transponder of the type having a stem extending from a housing with said stem having a size sufficient for expanding said passageway when moved therethrough to allow insertion and removal of said stem into and from said portion of opening.
