ABSTRACT:
A thin walled, plastic, disposable lid is provided having a generally circular closure wall including an integral peripheral skirt depending from the rim portion thereof. The closure wall is divided into a central portion and an annular outer portion with the annular outer portion lying in a plane below that of the central portion. The two portions are connected by way of a U-shaped recess which has a bottom wall lying in a plane below that of the annular outer portion. A plurality of lug members extend downwardly from the bottom wall and are positioned at predetermined segments of the bottom wall. The lug members also extend downwardly a predesigned distance so as to position the bottom wall of the recess of a first lid in a stack coplanar with the central portion of the lid on which the first lid rests. Also, the peripheral skirt includes a plurality of inwardly directed lands with a plurality of flutes of varying circumferential lengths positioned between the lands in order to space the lands about the skirt.
