ABSTRACT:
A large volume container and a closure therefor interlock and form a gasketless seal which will withstand a substantial drop of the filled container assembly. A rim portion of the closure provides an annular recess which receives the upper rim of the container, and interlocking members of the rim portion and the rim effect a snap-fit of the closure to the container. A sealing bead projects upwardly of the container rim and a pair of annular sealing flanges depend from the upper end of the recess, and when the rim is received in the recess, the sealing bead extends between, spreads apart and seals with both the inner and outer sealing flanges.
