Abstract
A paperboard box is intended for containing pop-up greeting cards and their envelopes. The box includes an additional front cover flap which folds away from the box's front panel section along a hinge line running up one side of the front panel of the box; pop-up figures rise from the box front and the inside surface of the cover flap when the cover flap is moved away from the front section. The cover flap and front panel are removably held together by a fastener, preferably a hook-and-loop fastener (such as VELCRO). The box and the front cover flap may mimic the front and insides of the pop-up greeting cards held by the box, so that buyers need not open the box or handle the cards to examine them. Preferably the front cover flap and the front of the box are both formed of doubled layers of paperboard, so that the pop-up figure cuts are not visible from either inside or outside the box when the cover is closed. The invention also includes a one-piece paperboard blank adapted to be folded and glued to make the box.
