Claim 13:
14. A kit comprising
(a) a first cap for closing an opening in a lid for a container wherein the first cap comprises
a generally planar circular top wall having a top surface and a bottom surface, wherein the top surface comprises a centrally disposed recess configured to receive a tool to rotate the cap; and
a cylindrical projection on the bottom surface comprising a screw thread configured to engage a complementary surface at the perimeter of the opening in the lid wherein the cylindrical projection comprises an outer surface comprising the screw thread;
wherein the top wall has a diameter greater than a diameter of the cylindrical projection and comprises a plurality of planar projections disposed circumferentially around the top wall and extending beyond the diameter of the top wall; and

(b) a second cap for closing an opening in a lid for a container wherein the second cap comprises
a generally circular top wall having a top surface and a bottom surface, wherein the top surface comprises a centrally disposed recess configured to receive a tool to rotate the cap; and
a cylindrical projection on the bottom surface comprising a screw thread configured to engage a complementary surface at the perimeter of the opening in the lid;
wherein the top wall has a diameter equivalent to a diameter of the cylindrical projection wherein the cylindrical projection comprises a central cylindrical recess defining a sidewall extending downward from the top wall comprising an inner surface of the cylindrical projection wherein the inner surface comprises the screw thread.
