Abstract: A container closure is disclosed which includes a shell attachable to a container around a container opening thereof. The shell has a shell opening in fluid communication with the container opening when the shell is attached to the container. A tip is received on the shell movable between a closed position sealing the shell opening and an open position. A cover is releasably attached to the shell in a manner indicative of the tip being positioned in the closed position when the cover is attached to the shell. Both the shell and the cover may be provided with tamper-evident bands. The present invention is particularly well adapted to be formed as a push-pull container closure for sports bottles and the like.

Abstract: In accordance with the instant invention, biaxially oriented polymer sheet is produced by continuously forging polymer feedstock between a pair of converging belts in an isochoric deformation region to form the sheet from the feedstock. The resulting sheet is immediately annealed after being formed and subsequently cooled after being annealed by passage through an isobaric region defined by a pair of opposed parallel belts backed by a pair of opposed parallel platens which interface with the belts via an oil seal so as to transfer heat from the sheet through the belts to the cooled platens. The resulting sheet has substantially uniform strain distribution over the width and length thereof as well as through the thickness thereof while maintaining its flatness after emerging from the apparatus.
