Abstract
A protective carton for a substantially flat product such as an electrical printed circuit board includes not only parallel rectangular exterior top and bottom panels, parallel rectangular exterior side panels, and parallel rectangular exterior end panels but also rectangular interior top and bottom panels and at least a pair of rectangular interior end panels. Each of the interior end panels forms an acute angle with respect to the interior bottom panel in order to clamp the product securely in place on the interior bottom panel. Each interior end panel is formed by lateral extensions of the interior top and bottom panels, with the lateral extensions of the interior top panels locking the lateral extensions of the interior bottom panel in place. The entire carton may be made of a material such as corrugated cardboard in order to minimize cost and facilitate eventual disposal.
