摘要

The package has a rectangular shaped base panel (2) and two cover panels (3, 4) articulated around folding lines (4p) that are placed on sides of the base panel. Wedging units (10, 11) are placed on the base panel between the lines. The wedging units form bellows with upper walls (10s, 11s) that are set parallel to the base panel and two lateral walls (101, 102) deformable in height. The lateral walls include two wall elements articulated around edges (102c). The edges are rotated toward interior of the wedging units.
