ABSTRACT:
A composite closure with a side seal proportioning lip is disclosed, with the closure including an outer plastic closure cap, and a plastic sealing liner positioned adjacent a top wall portion of the cap. The sealing liner includes a central disc-shaped portion, and an integral relatively thick, annular sealing bead portion. The closure is thus configured to effect a "top/side seal" with an associated container. The construction includes an annular liner-retaining lip having a relatively flexible annular inner edge portion which coacts with the sealing bead portion of the liner to self-adjust and proportion the degree of sealing engagement between the sealing bead portion of the liner and the associated container.
