ABSTRACT:
A container for pancakes of recording tape has an L-shaped base, mandrels extending horizontally from the base on which pancakes are placed, and a cover which encloses the pancakes. A compression ring provides a compression load to hold the pancakes together. The compression ring is placed around and rotated onto the outside of the mandrel. The compression ring includes an inner ring and an outer ring which engage each other. The outer ring is rotated relative the inner ring to apply the pressure on the pancake cores. Alternatively, the compression load is applied by a callapsible, one-piece unit. Two retractable wings are mounted on the free end of the mandrel and extend to engage the pancake cores. Rotation of a shaft forces the wings toward the pancakes to apply the compression load.
