Abstract
An improved linerless plastic closure for large mouthed bottles and jars includes a plurality of ribs, at least one of which is wavy, projecting downwardly from the undersurface of the closure so as to contact the upper edge of the bottle or jar mouth. The wavy ribs give better surface contact with the upper edge of the bottle than conventional circular ribs.
