A pail assembly, preferably all plastic, is provided in which a pail has peripherally spaced pail lugs on its side wall adjacent the rim of the pail. The pail lugs have an inclined cam surface at one end and a bearing surface substantially parallel to the rim along a margin remote from the rim. A lid has an internal annular skirt on and integral with it, of a shape and outside diameter complementary to the inside surface of the pail side wall adjacent the rim so that the skirt and pail surface engage one another snugly when the lid is rotated into mounted condition on the pail. The lid has an annular flange integral with it, spaced radially outboardly of the skirt and defining with the skirt a channel having a closed bottom wall and an open mouth. A plurality of peripherally spaced, radially inwardly extending lugs are formed integrally with the flange. They are spaced axially outwardly from the closed bottom wall of the channel and are of a peripheral length less than the space between successive pail lugs with which the flange lugs are to engage. Sealing means, preferably an annular tubular gasket, are provided between the channel bottom wall and the rim of the pail, the sealing means being in compression when the pail lug bearing surface and flange lug bearing surface are engaged by a turn of the required number of degrees.

In a pail assembly including a pail having a side wall with a rim circular in top plan, and a plastic lid capable of being sealingly mounted on said pail, the improvement comprising an annular rib extending uninterruptedly around the pail rim, a plurality of peripherally spaced pail lugs on and integral with said side wall adjacent the said rim, each of said pail lugs having a rib parallel to, in the same plane with, and spaced outwardly radially from the uninterrupted rib of the rim, and, along its lower surface at one end an inclined cam surface tending away from said rim; said lid having an internal annular skirt on, integral at and along its upper edge with and depending from said lid, and of a shape and outside diameter complementary to the inside surface of the pail side wall adjacent said rim for engaging one another snugly when said lid is mounted on said pail, annular flange integral with said lid, spaced outwardly radially of said skirt and defining with said skirt a channel having a closed bottom wall and an open mouth, said bottom wall having an annular nose, projecting from the bottom wall toward the open mouth, which, when the lid is mounted, is positioned radially between the uninterrupted rim rib and the lug rib, a plurality of peripherally spaced radially inwardly extending flange lugs integral with said flange and spaced outwardly from said closed bottom wall toward said open mouth, of a peripheral length less than the space between successive pail lugs with which said flange lugs are to engage, said flange lugs having a bearing surface extending radially inwardly and shaped and positioned to engage a pail lug bearing surface, said nose, side walls of the flange and skirt bottom wall defining a gasket seat, and an annUlar gasket seated in said seat, said gasket being compressed between said nose and said ribs when the lid is mounted on the pail.
