<p>Packaging consisting of a wrapping of flexible material, delimited by generally triangular walls (4, 6, 8, 10), so as to define an essentially tetrahedral containment volume, characterized in that it comprises mutual engagement means (14a, 14b) which are associated with the common sides (12) of a first pair of adjacent walls (4, 10) and which are designed to disengageably interconnect said walls in order to allow opening and closing of the containment volume and in that the common sides (24) of the other pair of adjacent walls (6, 8) are interconnected by a welding region (26) where end overlapped edges (27 and 29) of the walls of said other pair are welded together.</p> |
