A resilient plastic lid closure (10) for the upper rim (20) or a bowl (15) or the like, said lid having a downturned periphery (16) terminating in an outer rim flange (18) for snapping over the rim (20) when pressed downwardly at the medial portion (11) of the lid, thereby forming a tight seal with the outer surface of the bowl rim (20) when pressure on the medial portion (11) of the lid (10) is released.

A resilient plastic lid adapted to form a tight seal with the outer surface of the upper rim of a container, said lid having a top wall having a downturned periphery terminating in an outer rim flange for fitting over the container rim, the inner diameter of said rim flange being slightly less than the outer diameter of said container rim, said top wall having such resiliency and beam strength that when pressed downwardly at its medial portion said rim flange will flex outwardly and snap over the container rim with an audible click, and when released will draw said rim flange radially inward to tighten its sealing engagement with the container rim.
