As shown in Figures 1 and 2, the container [8] includes a
vessel [10] and cover [40]. The vessel [10] has a generally
flat, oval bottom [12] and a wall [14] extending substantially
vertically upward therefrom. A lip [18] runs along and

to vessel [10]. In order to provide a liquid tight seal for
the contents of vessel [10], the inside surface of the vessel

includes an annular ridge [52] which locks into mating recess
[54] when the cover is lowered onto the opening of vessel
[10].
