ABSTRACT:
A closure having an inner retaining area for receiving a closure liner. The liner circumferentially contacts the land surface of the container to cover the mouth of the container upon application of the closure to the container. A well, formed around the outer peripheral edge on the inside of the closure is dimensioned to receive the land surface of the closure. The well includes an upper surface having integrally depending flexible teeth. The walls of the well together with the teeth provide a directional force against the liner causing the liner to wrap around the land surface to increase the amount of liner to land surface contact and thereby counter the effects of irregularities on the land surface. The teeth also provide a localized compression force down against the liner to further increase the sealing contact between the liner and the land surface.
