Abstract

A CD package has a plastic tray with a central recess for receiving an holding a compact disc. Downward extensions on sides of the tray have inward projecting rails. A paper board has two panels and an intermediate spine separated by creases. One of the panel forms a base for permanent attachment to the tray. The base has side edges with recesses which cooperate with the downward extensions. Distance between opposite inner edges of the recesses is the same as distance between opposite inner surfaces of the downward extensions. The paper board and tray are permanently assembled by curving the paper board, bringing the paper board and tray into contact with the recesses in edges of the board aligned with the downward extensions of the side walls of the tray. Releasing the curvature of the board pops the board into place with the recesses engaging the downward extensions. Edges of the base lie along edges of the tray. The spine covers the back of the tray, and the second panel covers the tray. Multiple tray packages are created by enlarging and adding spines and panels and forming recesses in the side edges of each panel which will hold an identical tray.
