Abstract
A CD package including a CD holder and a foldable cover for the holder. The CD holder includes a tray and base in telescoping relationship, one of the tray and base being glued to the foldable cover. The CD holder includes edge projections and recesses which cooperate with edge projections and recesses of other CD holders to allow stacking of the CD holders to facilitate automated assembly. The base and tray also include ramped stops and cooperating projections, respectively, inward of the sides, to releasably lock the tray and base in the telescoped and untelescoped positions. Tabs are provided on the sides of the base to abut the tray and improve stability of the base relative to the tray in the untelescoped configuration. A transparent window is assembled on an end cap via a tongue and groove connection and then welded. Detents are added adjacent a recess formed on each side wall of the end cap, which recesses cooperate with a projection on the tray to connect the cap and tray. The detents reduce friction between the end cap and tray to ease opening of the cap. Finally, the base and end cap include a waffle-like texture to improve adhesion of these members to the foldable cover …
