摘要

The package is constituted by a frustum of a prism whose faces form an outer enclosure and have a prismatic opening or cavity having the same vertical axis. The faces of the cavity form an internal frame. The vertical faces of the prisms are parallel. The vertical faces are obtained by folding a blank of semi-rigid material such as corrugated cardboard. The vertical faces are connected by a combination of elements cut out from the faces so as to form an elastic connection.
