ABSTRACT:
A pail assembly including a plastic pail and a plastic lid which can be snap fit sealed to the top of the pail. To reduce excessive outward doming of the lid and the pail floor caused by internal pail pressures, due for example to chemical reactions of hazardous material contents, rib structures are formed on and extend across the interior surfaces of both the floor and the lid. To prevent this doming the floor is also formed to be bowed upwardly at its center with a small curvature radius. A large radius connection of the floor to the pail sidewall better distributes impact stresses. A locating ring channel is formed on the lid surface and is dimensioned to receive therein the feet of two different size pails when the pails are loaded and stacked. Ribs on the outside and inside of the channel resist the tipping of the pails of either size when alternatively stacked thereon.
