Lid with sealing protuberances

Abstract

A pail includes a container and a lid. The container includes a base, a container sidewall extending upwardly from the base to an upper rim, and a sealing rib extending from the container sidewall adjacent to the upper rim. The lid includes a channel for receiving the upper rim of the container, the channel includes a channel base, a plurality of protuberances arranged spaced apart on an inner surface of the channel base and extending downwardly therefrom, a first channel sidewall, and a sealing shoulder that projects inwardly from the first channel sidewall. When the upper rim of the container is received by the channel of the lid, the protuberances abut the upper rim and the sealing rib engages the first channel sidewall and the sealing shoulder. The protuberances can urge the sealing rib downwardly against the sealing shoulder, to thereby form a seal.
