Abstract

A liner for use with a threaded closure cap is formed of a relatively thin, flexible material having a central portion configured for placement in the cap abutting a top wall thereof. The liner has at least one tab extending therefrom. The tab has a leading edge portion that is formed so as to define an angle relative to a tangent line adjacent to a juncture of the tab and the central portion. The angle of the tab is configured to be the same as the angle of the threads in the closure cap so that the tab rests fully against the threads prior to application of the closure to an associated container.
