Abstract
A liner disc for a bottle cap for sealingly closing a bottle includes an annular rim portion and a downwardly domed portion depending from the annular rim portion. The domed portion is convex toward the contents of the bottle. A seal layer is provided on the domed portion. Internal pressure of the contents of the bottle acts in a direction tending to flatten the domed portion which in turn expands an annular side wall of the domed portion outwardly to press the seal layer against the inside surface of the bottle to assist in effecting a seal between the bottle and the cap.
