    Abstract: This disclosure depicts an improved shipping and/or storage container for television cathode ray tubes or funnels. The container has a base, a cap, and preferably one or more intermediate shelves. The base and the cap are separated by a plurality of rigid posts which give stacking strength to the container. The base defines a plurality of cavities configured and sized to snugly receive the faces of a plurality of facedown tubes (or funnels). Each shelf has openings configured and sized to permit the shelf to fit over the face-down tubes (or funnels) and other openings for receiving a plurality of face-up tubes (or funnels). Each shelf, when assembled, rests on the face-down tubes (or funnels) and supports the face-up tubes (or funnels) in space-conserving relationship between the face-down tubes (or funnels).
