A pail consists of an open-top body and a lid applicable to the open-top to close it and be reliably secured thereon. The open-top is defined by an annular seating, and a circumferential array of cantilever locking lugs on the body adjacent but spaced from the seating, project radially beyond the seating. The lid has a depending skirt which encircles the seating, when applied, and extends downwardly below said lugs. A series of circumferentially extending locking apertures, equal in number and spacing to the lugs, are formed in the skirt, each having one enlarged end to freely admit one of the lugs and its other end formed as a stricture to take hold of an admitted lug upon fractional rotation of the lid following application to the open-top. A resilient sealing ring is housed in a groove in the lid so that when the lid is applied to the open-top, the ring is compressed between the lid and the body seating. |
