Plastic container and lid

A plastic container and a lid having a pre-installed position and an installed position, said container comprising a bottom, a body and an open end with a rim having an outer channel and said lid comprising an inner channel on its periphery, said outer and inner channels each having two interior walls and an exterior wall and all of said walls having projections therefrom, each of said projections being sized to slide by and engage one of said projections from the other channel to define said installed position, so that in said installed position three complementary pairs of said projections create a liquid tight fit and there is flexibility between the rim and the lid.

A plastic container and lid, said container comprising an open end with a rim on the top and a closed end on the bottom, said lid at its periphery comprising an inner channel facing toward the bottom and the rim comprising an outer channel slightly larger than the inner channel and facing in the same direction as the open end, the inner and outer channels each comprising a first and second interior wall and one exterior wall, each of the interior walls of the channels defining a first and a second interior space, and further comprising a projection from each of the three walls so that, when the inner and outer channels are pressed together, each of said projections on the inner channel slides past and engages a complementary projection on the outer channel, and each of said complementary pairs of projections produces three seal/latch combinations and an over-travel in the first and second interior spaces.
