Claim:
A plastic container comprising: a generally cylindrical main body having a closed end defined by a bottom wall, and an open end defined by a circumferential lip at an upper end thereof; a rim assembly connected to the main body, the rim assembly including a continuous, annular channel defined along an outer edge by a channel sidewall and along an inner edge by a flexible finger having a locking tab including an inner peripheral surface and an outer peripheral surface to define a locking tab width, the channel sidewall being connected to an outer peripheral edge of the rim assembly by a generally horizontal connector portion, wherein the channel sidewall is spaced radially inward from the main body such that the channel sidewall does not contact the main body, the outer peripheral edge including a groove for receiving the lip of the main body; and a lid adapted to be connected to the rim assembly, the lid including a second continuous annular channel having a channel width less than the locking tab width, the second annular channel having a downward projection received in the first channel, the downward projection having an outer annular shoulder supported on the horizontal connector portion of the rim assembly when the downward projection is engaged in the first channel, wherein when the second annular channel receives the flexible finger, the locking tab on the rim assembly flexes such that the outer peripheral surface of the locking tab engages a locking notch and the inner peripheral surface engages an inner wall defining the second annular channel to form a liquid tight interference therebetween, wherein the bottom wall on the main body including structure for stacking containers one on top of the other, the bottom wall having an annular flange adapted to be received between an outer annular shoulder and an outer peripheral edge an outer, of another container when stacked thereon, the bottom wall further having a support leg which is adapted to rest upon the top surface of an outer peripheral edge of the container to provide support for the bottom wall.
