Container lids

A container lid comprising:

• an upper member having, relative to an intended orientation when the container lid is placed on a container, a top surface and a bottom surface;
• a sidewall extending downwardly from the bottom surface of the upper member from a top joining the bottom surface to a bottom spaced apart therefrom;
• an opening formed extending through the top and bottom surfaces of the upper member adjacent to, and radially inward of the top of the sidewall;
• and
• at least one ring structure attached to the bottom of the sidewall, wherein at least a portion of the ring structure is embedded with fluorescent material;
• wherein the upper member has a skirt about its entire periphery extending radially beyond the sidewall such that a radial outer edge of the bottom surface of the upper member is located radially outward of the top of the sidewall and a portion of the radial outer edge forms a radial outer boundary of the opening;
• wherein all of the sidewall and of the upper member including the skirt are formed as a solid, co-molded transparent piece, such that illumination from the fluorescent material of the at least one ring structure remains visible through the upper member with the container lid placed on the container;
• and
• wherein a fluorescent portion is located on the radial outer edge of the bottom surface of the upper member at the portion forming the radial outer boundary of the opening such that illumination from the fluorescent portion is also visible through the upper member with the container lid placed on the container and the opening is easily viewed in a dark environment.
