The invention claimed is: 1. A seal removably mountable to the rim of an open container as a closure for said container, said seal comprising a base panel having an outer periphery with means for releasably engaging the seal to a container, said base panel having an upper face and a lower face, multiple upwardly directed protuberances on said upper face, said protuberances being spaced from each other and defining recesses therebetween, each recess being of a configuration substantially conforming to a protuberance on said lower face, whereby a second seal with duplicate protuberances and recesses will, when inverted and engaged with the first mentioned seal, engage the protuberances and recesses of said first seal, and wherein said seal further comprises means on each protuberance laterally directed toward adjacent recesses for releasable engagement with a recess received protuberance of a duplicate inverted seal. 2. The seal of claim 1 wherein the protuberances are peripherally spaced about the outer periphery of the base panel and converge inwardly from and relative to the outer periphery, said protuberances terminating at inner ends spaced from each other centrally of said base panel. 3. The seal of claim 2 wherein each protuberance is of a generally triangular configuration with a base edge at said outer periphery and an inner apex at the inner end of the protuberance. 4. The seal of claim 3 wherein each protuberance has an outer surface upwardly convex and arcing from said base edge to said apex, each said protuberance being of a maximum height between said base edge and said apex, each said recess being concave and complimenting the convex outer surface of a protuberance. 5. The seal of claim 4 wherein each protuberance has opposed side edges converging from said base edge to said apex, said means on each protuberance for releasable engagement comprising an undercut portion between the base edge and the apex, said undercut portion defining a groove with a locking lip upward of said groove, whereby each groove is adapted to receive a locking lip of an inverted duplicate seal upon engagement of the seals with the protuberances of each seal received within the complementary recesses of the other seal. 6. The seal of claim 5 wherein each protuberance side edge undercut portion is of a maximum height at a central portion along the side edge. 7. The seal of claim 6 wherein each undercut portion terminates short of the corresponding apex. 8. The seal of claim 7 wherein each apex is truncated. 9. The seal of claim 8 including a finger tab fixed to and projecting outwardly from said outer periphery of said base panel. 10. The seal of claim 9 wherein said tab extends generally at an angle downwardly relative to said base panel. 11. The seal of claim 10 wherein said tab, as an alignment means for overlying seals, aligns with one of said protuberance side edges. 12. The seal of claim 9 wherein said tab, as an alignment means for overlying seals, aligns with one of said protuberance side edges. 13. The seal of claim 3 wherein each protuberance has opposed side edges converging from said base edge to said apex, said means on each protuberance for releasable engagement comprising an undercut portion between the base edge and the apex, said undercut portion defining a groove with a locking lip upward of said groove, whereby each groove is adapted to receive a locking lip of an inverted duplicate seal upon engagement of the seals with the protuberances of each seal received within the complementary recesses of the other seal. 14. The seal of claim 1 wherein each protuberance has opposed side edges, said means on each protuberance for releasable engagement comprising a groove with an overlying locking bead, whereby each groove is adapted to receive a locking bead of an inverted duplicate seal upon engagement of the seals with the protuberances of each seal received within the complementary recesses of the other seal. 15. A seal removably mountable to the rim of an open container as a closure for said container, said seal comprising a base panel having an outer periphery, and upper face, and a lower face, said base panel having multiple upwardly directed protuberances on said upper face, said protuberances being spaced from each other and defining recesses therebetween, said recesses being configured to substantially conform to each protuberance on said upper face, wherein each protuberance is of a generally triangular configuration with a base edge at said outer periphery and apex at the inner end of the protuberance, and opposed side edges converging from said base edge to said apex. 16. The seal of claim 15 wherein each side edge, along a major portion of the length thereof between said base edge and said apex is undercut and defines an elongate groove therein with a bead defined outward of and along said groove. 17. The seal of claim 16 including a finger tab fixed to and projecting outwardly from the outer periphery of said base panel, said tab extending generally at an angle inclined outward and downward relative to said base panel.
