Abstract
A closure having an axially movable insert disk which is lifted by a bead around the inside of the closure shell to open a sealed container. When the closure is in sealing position on the container, the lifting bead lies below the top of external threading on the container, and at the top of cooperating internal threading of the closure skirt. The bead has an inside diameter greater than that of the closure threading, and can move upwardly past the external threading on the container. The overall heights of the closure and the container finish can thereby be reduced and less material used.
