1. A lightweight overcap for a cylindrical container, said container having a beaded top and a closed bottom, said overcap comprising:a substantially planar covering portion having a flat central portion and a raised annular portion extending outwardly therefrom, said annular portion having an upper surface; a sidewall extending downwardly from the periphery of the raised annular portion and having an inner surface; intermittent arcuate shaped stacking lugs evenly disposed about the upper surface of the annular portion, said lugs aligned in a ring adapted to form a close fit with the bottom edge of a similarly configured container to facilitate stacking of containers with overcaps; intermittent, arcuate shaped nesting segments evenly disposed about the upper surface of the annular portion, said segments aligned longitudinally in a ring adapted to form a close fit with the inside of a similarly configured overcap to facilitate nesting of overcaps, the nesting ring and the stacking ring having different diameters; and locking detents evenly disposed about the inner surface of the sidewall and extending inwardly therefrom, said detents adapted to form a snap fit with the beaded top of the container to secure the overcap to the container.
